Dale Hache, our first LongMill MK2 beta tester

A few weeks ago, Leandro, Scott, and I went over to visit Dale and interview him about his experience with the LongMill. It was a fantastic and fun trip for all of us, especially spending time with a fun character like Dale. Here’s our interview!

About the beta testing program

Just as a quick intro about the beta testing program, at the end of last year, we recruited three different people of different backgrounds and skill levels in our area to test the LongMill MK2. At this point, we were at the final stages of our development for the MK2 and were looking to iron out the rest of the kinks to finalize the production of a few of the parts. All beta testers paid for their machines, albeit with a small discount. Each beta tester volunteered their time and space to observe and interview them at each step of the process as well as testing prototype and production parts as they were made to update their machines.

Working with Dale

It has been so fun to work with Dale. Just as a background, we would consider Dale a “superuser”. Dale initially had the LongMill MK1 in his shop that was used regularly for his side business. You might also recognize him as a very helpful and active member of our Facebook Group as well.

Because we knew how much he was using his MK1 and how long and intricate many of his projects were, we knew that Dale would really put the MK2 through its paces. And this happened to be true, especially as he took this opportunity to transition from working a job for someone else and transitioning to working full time for himself.

As someone who’s more focused on building, engineering, and selling CNC machines, it’s really satisfying to meet people like Dale who’ve gone from working a regular 9-5 and being able to work for themselves and express their creativity in their craft using our machines.

Dale is now also beta testing the extension kit on his original MK1 machine. We’re looking forward to all the new creations that’ll be coming down his pipleline!

LongMill MK2 Configurator

A common query we get here at Sienci Labs is “What should I order with my LongMill?”.
We’ve created a new step-by-step configurator to help customers figure out what they should be ordering with the LongMill. The LongMill MK2 Configurator covers all of the add-ons and toolings that we feel are relevant for someone getting set up with a new machine, as well as providing better info and transparency of what each item does.

Why this matters to us

One of the interesting results of being in control of how the order page looks on our website is that it influences the purchasing decisions of our customers and changes what is and isn’t easily visible to the customer. The consequence of this is that most of our customers purchase all of the add-ons we have on the product page, even though some of these items may not be needed for most beginners.

For example, we typically do not recommend beginner users to use or install inductive sensors until they have gained some experience using the machine. For the dust shield, we also don’t feel it is required for most customers. However, more than 50% of customers choose these options as default. Although it means more money in our pocket at the end of the day, we would prefer customers to be able to purchase the things they need and have the best experience possible.

Another result of this layout is that there are some confusion and order changes that happen, as we don’t list all of our add-ons on the product page. For example, we have our regular touch plate on the list, but not our AutoZero touch plate. Many customers have ended up getting in touch with us to change their regular touch plate to the AutoZero touch plate. With an improved system like the configurator, we can lay out more options and give people the opportunity to compare their options more easily, as well as reduce the overall clutter of the page.

We’re hoping that this improves overall customer and ordering experience, while better informing customers on what they need with their machine.

Depending on the reception of the configurator, we may implement it on other products, like the LaserBeam and LongMill Extension kits. If you have any thoughts or feedback, feel free to reach out and let us know!

May 2022 Production Updates

Hey everyone, here’s our May 2022 production update.

Overall production continues to move along smoothly and machines are going out the door at a good pace. In a good way, we don’t have too much to report on.

Just as a reminder, if you’d like to get these updates as a weekly email newsletter, please subscribe here: https://sienci.us13.list-manage.com/subscribe/post?u=720f140325aaa668a8aa09916&id=e18d59a085

Lead times for LongMill MK2 12×30 and 30×30 orders

We’re excited to be getting through the rest of the queue on the LongMill MK2 12×30 and 30×30 orders sooner than expected. Patrik and the rest of the packing crew have now pushed out over 400 machines over the last four weeks, and are expecting to complete the rest of the queue sometime next week. This means that new orders should ship in 2-3 weeks placed today.

Incoming materials and production

Production has been moving along slowly without part shortages. Once the queue is complete, we are expecting to have enough parts to pre-pack and ship another 70 machines with the gantries and steel parts that we currently have. Another batch of these parts is expected to arrive in about 2 weeks, so we believe that we’ll be able to continue packing and shipping as orders come. After these parts arrive, we’ll have plenty of material to keep us busy for the next 2-3 months.

It’s been a while since this has happened, but we’re now at the point where our production capacity is exceeding our demand, and our goal is to get things packed up and ready to go as more folks get their machines and word on the LongMill MK2 continues to spread.

Some other general news

  • Our company is growing. We have a couple of new people joining our team in marketing, operations, and engineering! We’re also working on hiring new folks for software development and customer support.
  • The LongMill MK2 assembly video is being edited now and we are expecting it to go live in the next week or two.
  • Check out Dana’s latest video where he shows off his new MK2 and extended 48×30 MK1 machines! https://www.youtube.com/watch?v=Mi6Dqqvy-pI

Completed Order Emails and Tracking Notifications are Back Online

Hey everyone, just wanted to let everyone know that the completed order emails with the tracking information issue from last week have been resolved and the site is operating as normal. Customers should now continue to be getting emails with their tracking numbers as their orders are complete and shipped.

If you had an order during this time period, we sent the tracking order manually as they were shipped. If you didn’t get one, please feel free to contact us. You can check if your order has been shipped and where it is in the queue with our Order Status page.

Customers with order numbers 39363 and higher, or orders placed after April 28th, should see the tracking numbers emailed as normal automatically.

Thank you everyone for their patience, we’re glad this has now been resolved.

So what happened exactly

It appears that starting from April 14th, completed order emails for some orders (specifically for the ones that are for LongMill MK2s) were not being sent. We were not aware of the issue until we returned from our long Easter weekend. Our current system has been set up to send emails in several different stages:

  • When we receive your order: an email is sent to the customer when the order has been created and successfully paid for. If there is an issue with your payment you will get a different email to notify you.
  • When we complete and ship your order: an email is sent when the order is ready for pick up (which comes with instructions and times that your order can be picked up) or has been shipped (which comes with tracking info as well as additional info about duties and taxes).

In some cases, there may be additional emails, such as for software licenses and if we need to notify you of packing status.

At first, we checked the status of different plugins of the site, as updates were done on different areas to see if there were any changes to the site between the 14th and 18th. However, there were no changes to the plugins during this time, and reverting back to older versions of the plugins for testing did not fix the issue.

First, we received some error notifications from the site, citing some issues with the software license system. However, the issue was still not fixed after testing with the system disabled and rolled back.

Next, we also started receiving error notifications in parsing code in the code used to generate the emails. At first glance, the HTML was correct and was code that had been used previously for a long time. However, we found that the PHP version was updated on April 14th, which may be causing issues with parsing HTML in this case. Removing this code has fixed this issue, and the emails are now being sent without the parsing error.

We have reverted the email to the same format as previously through another method for customizing emails, which we expect will help keep the system working in future updates.

April 2022 Production Update Pt.2

Hey everyone, here’s just a quick update about the production here at Sienci.

By the way, we are having a livestream on Youtube tomorrow, if you’d like to be part of it, we’ll be live at noon (EST) on Friday April 22! This livestream will cover some of the development work happening at Sienci Labs as well as a bunch of stuff about the LongMill MK2.

Shipping

We’ve been working hard to get as many machines out the door as quickly as possible. Now, at the time of writing, we’ve just about shipped 250 machines. Our support team has been reporting that issues have been fairly low and comments about the machine have been overall very positive! If you’d like to follow along on our progress, feel free to check out our page here: https://sienci.com/order-status.

We’re expecting to keep up with packing as we are currently. Please make sure to stay tuned for more updates.

Email notification issues

UPDATE: As of April 28th, we have fixed the email notification issue and tracking information is now being sent automatically as orders are completed. For more info, please see our post here: https://sienci.com/2022/04/28/completed-order-emails-and-tracking-notifications-are-back-online/

We’ve recently run into an issue (since April 18th) where shipping notifications for LongMill MK2 orders are not being sent. All other email notifications for orders (parts, bits, and other products) are being sent, and the only orders that are being impacted are the ones with LongMill MK2s. In the meantime, we are sending out the notifications manually, so please keep an eye out for them. We are continually working on fixing this issue, and if your order is showing completed on our Order Status page, please get in touch with us for the tracking info.

We suspect that there may be some bugs with the system as there was some updates that happened around this time. We’ll continue monitoring the emails being sent out so that we can keep folks updated as best as we can.

We are also experiencing some issues with auto-syncing orders with the Order Status page, so we have been updating it throughout the day. Please note that there may be a bit of delay day to day on the status of the items on the page until we fix the system.

Incoming materials

We’ve now reached the first 500 machines sold for Batch 6, which means that we are now about a third of the way through. We currently are stocking 1500 machines worth of parts, with the exception of the rails and the gantries. We initially ordered 500 sets of rails and gantries to start the batch and we’ve placed another batch of those parts to come in soon.

Materials for rails which were slated for early June arrival have been completed early and are expected to be delivered to us soon. Some will be here tomorrow and some will be here next week. This also covers the rails we need for the 48×30 machines and extension kits, which means that we’ll be starting prepping and cutting for those orders as well.

Gantry plates and feet are in production currently, and we are expecting all of them to be cut, formed, and painted at the start to middle of May. Once those parts are available, these parts will be used for machines for the next 500 units.

Initially, we were expecting to start shipping machines after the first 500 in June, but it looks like we’ll be able to chug along with production without interruptions.

LaserBeam Drivers

If you didn’t see Ikenna’s update for the LaserBeam, please make sure to read it here: https://sienci.com/2022/04/14/laserbeam-driver-delay-update/

We are currently working with Bittele and other PCB manufacturers to work on getting drivers in as soon as we can.

April 2022 Production Update

Hey everyone, here is our April 2022 production update.

Just as a reminder, if you’d like to get these updates as a weekly email newsletter, please subscribe here: https://sienci.us13.list-manage.com/subscribe/post?u=720f140325aaa668a8aa09916&id=e18d59a085

I’m happy to announce that the LongMill MK2s are now shipping! We received our container last week and have started shipping since. Here’s some customer feedback from one of the first people to pick it up:

MK2 Production

At this current time, we now have enough materials on hand to ship around 500 machines. Our team continues to pack and assemble kits as quickly as we can. At the time of writing, we’ve gotten 48 machines shipped out since last Thursday.

For general updates on where your order is on the list, please see our Order Status page. An estimated time for shipping can also be found on the page. We are aiming to average around 50 machines shipped per week. Please note that this number can vary a lot depending on staff availability and production schedules. Please also note that this is an average we are shooting for, but the number may vary day-to-day, as some days we may be able to ship more than others. Because of this, we cannot provide exact dates on when machines will ship for each order, but an email will be sent the week before your order is ready to ship to let you prepare and let you know that things are heading your way.

I’ve updated the estimated time to completion on our Order Status page to reflect our expected delivery times. Please make sure to check it out for our latest estimate on when your machine will ship.

We are expecting the first week to be a little bit slower and for things to pick up as we keep packing since some of our new packing material which was designed to improve our packing speed has not arrived yet and we are using general off-the-shelf material in the meantime. The new packing material is expected to arrive this week, but it has previously been pushed back a few times and it hasn’t been clear the exact delivery date due to cardboard shortages.

Materials

We now currently have the material needed to build the next 500ish machines, which means that we have everything we need to cover all of the machines in queue currently. We are still waiting on some additional packing material to arrive, but for the time being, we’ve substituted final production packaging with some off-the-shelf materials we were able to use in the meantime.

After the first 500 units, we’ll be waiting on another batch of gantries and rails to arrive, which is expected to arrive between the end of April and the start of June. The arrival of these materials is likely to affect our lead times down the line.

Purchasing for materials for Batch 7 has also started, which should put us around August-September when we’ll start Batch 7.

LaserBeam

Power supplies and heatsinks for the LaserBeam have arrived, and we are currently packing and assembling kits. Here’s one of our staff putting together the laser and heatsinks.

We’re expecting to start shipping the kits out at the end of the week this week or the start of next week. Ikenna is waiting on Bittele to wrap up the PCB assembly to finish up the drivers on Thursday. There were some delays due to chip and parts shortages for the assembly, but the boards have started fabrication last week. We’ll have around 400 new drivers arriving to wrap up the production for the rest of the LaserBeams.

Other general updates

Chris has made a lot of progress in the assembly instructions for the MK2 machines. Make sure to check it out in the resources. Thank you Aleks for being part of this project as well!

I also wanted to share some pics of the new power supply:

You can see that when you cut it open (I used an angle grinder), it is completely encapsulated. Although this is pretty overkill, this construction will basically make the power supply impervious to dust and moisture.

Did you see our April Fools video?

Ikenna initially suggested the idea of making a lasergun using the LaserBeam. I thought that it was a great idea so I put one together.

Assembly of the Not-a-LaserGun

The Not-a-LaserGun was partially inspired also by the Not-a-Flamethrower, which was a flamethrower created by Elon Musk.

Basically, the Not-a-LaserGun takes the LaserBeam diode assembly and driver assembly and replaces the power supply with a 12V 8A battery to allow the user to use the laser on battery power. Everything was then put into a case that was 3D printed in multiple parts. An Arduino was used to generate an on-signal when the trigger is fired.

The result of this was basically a super-powerful laser pointer that can burn stuff.

Extension Kits and MK2 48x30s

We now have three people with the extension kits. Dale, Garrett, and Dana. These guys also all have MK2 machines as well, so they will be able to compare the MK1 and MK2 as well. So far, the response has been very positive, with very few issues with the overall setup. There are a few kinks to work out however which include

  • Proper defaults and integration on gSender
  • Testing and finalizing designs for wire management
  • Instructions and other resources for assembly and use

We’ve asked our users and testers to start extending their MK1 machines since…well this is what I said:

We also just got in the aluminum part to adapt the new T12 nuts for the T8 spacing (used on the MK1 machines).

Please keep an eye out for further development updates and other feedback!

March 2022 Production Update Pt2. – Saga of delayed container MAGU5348230

Hey everyone, this is an update for this month’s production update, covering the status of some of the parts that we are waiting on to have come in as well as other details.

If you’re learning about the LongMill MK2 for the first time, please check out this post for more info.

Just as a reminder, if you’d like to get these updates as a weekly email newsletter, please subscribe here: https://sienci.us13.list-manage.com/subscribe/post?u=720f140325aaa668a8aa09916&id=e18d59a085

The TL;DR

We now have a definitive answer on when the power supplies we need to start shipping LaserBeams and LongMills again will be arriving to us. The container of parts and materials has been loaded onto the train this past weekend (March 19) and are expected to arrive in Brampton at the end of the week (March 25). Unloading to the warehouse can take between a few days up to two weeks. So we are conservatively estimating that the first units will start shipping at the start of April.

When will the LongMill MK2s start shipping? The saga of delayed container MAGU5348230

The last time we had a “saga” was back when we were scrambling to figure out the v-wheel situation. 2021 and 2022 shipping delays, especially for that last batch of parts have been another epic saga in itself.

Around June last year, we started Batch 5. Knowing the current world situation with COVID and everything, we started production on Batch 6 in the first quarter part of the production of Batch 5. This was the earliest we ever started sourcing parts for a batch, as we typically wait for the middle of the batch to start ordering parts. Batch 6 is also the largest batch we’ve ever created, as we wanted to hedge having part shortages by keeping more inventory on hand. With the majority of parts produced for Batch 6 being produced between August and December of last year, we expected to have a lot of buffer between each batch.

Well, then things went gangbusters from August to the start of this year, throwing our projection that we were going to run out of machines at the start of 2022 straight out the window. Instead, we ran out of LongMills sometime in December.

Given that we saw this upward trend happening, we had ordered as much stuff as we could early in advance. But there were a couple of minor issues. One of the biggest that is having repercussions now would be the chip shortage.

Due to the chip shortage, our regular suppliers for power supplies were 1) significantly increasing their prices 2) had an extremely long lead time that couldn’t deliver on schedule for our production. It was also uncertain if the power supplies could even be made, as the estimates we were getting relied on whether the chips would actually come back in stock again. With this going on, we started vetting and testing power supplies from other suppliers. For many producers, it was a similar story of very high prices and being unable to ship quickly due to the lack of chips.

Luckily we were able to work out the production for the power supplies with another manufacturer that was able to provide a high-quality product with the proper certifications and also have everything completed and ready to ship by December 1, 2021. Materials were picked up from the factory and prepped for transport on a cargo ship.

Although it was cutting it tight, we let customers know that we were expecting to start shipping LongMills in February to end of March, which would have given us just about 4 months to wait for the arrival of the power supplies. Back before the pandemic, ocean shipping speeds were fairly consistent and reliable, typically taking around 6 weeks for materials to arrive from China. Most delays, if any would generally be with loading and unloading, as sometimes things would get held up with customs or waiting for the next ship to arrive. During the pandemic, we saw shipping times shoot up to 8 weeks, and near the end of 2021, get to 12 weeks.

The estimated time that the power supplies and other parts would be arriving was January 30th initially, and we first set up our timelines based on this initial estimate. However, that has shifted due to delays in shipping. There were a couple things we believe caused these delays.

First was the aggregation of three other shipments that were getting sent here from China. We had two other shipments that were leaving from the same shipping company. We suspect that the shipper aggregated them together to save costs, rather than creating three separate shipments. Although when done properly, this does not affect the shipping time and usually is a win-win for both parties if the savings are passed onto us as well, combining shipments generally creates longer shipping times as each batch of cargo needs to wait on each other and can cause customs complications. Because of this, we never ask our shippers to combine cargo, and this was done without our consent.

Unfortunately, if we were to cancel the shipment, the time it would have taken to rebook shipments would offset any potential time savings for the shipment, so we had to go ahead with the current shipment.

Next was the trajectory of APL Vancouver, the cargo ship our stuff was on. Cargo ships can either make a straight trip from one port to another, and some will pick up and drop off cargo from multiple ports. In this case, it was the latter. Due to port congestion happening in many ports, this also added total transit time for our shipment. We weren’t aware of this until it was halfway across the ocean as well.

And lastly, general port congestion in Prince Rupert and on the rail system further delayed the shipment. According to Vanterm, the location that the container finally arrived at in Canada, there have been railcar shortages delaying containers from moving out of the rail terminal. Although our shipment arrived on Feb 13, 2022, it had been sitting waiting for rail cars to arrive for over 4 weeks.

So where does that leave us now? We now have confirmation that the shipment is now on rail and is expected to arrive on March 25th. Once the cargo arrives in Brampton, which is where the next railyard is, it will be unloaded and placed in a warehouse for pickup. Then we can arrange a truck to pick our shipment up and we’ll have everything ready to go for shipping.

Based on estimates from the shipping company, it takes roughly two days for unloading the train and two days for it to arrive at the warehouse. We are working on arrangements for a truck to go pick up the parts now so that it will be here the same day it is released.

So in regards to everything else, once we have those power supplies, we can start shipping. We have all of the other parts here to start shipping (minus some final packing materials), so we’ve been packing and prepping everything to go as soon as possible. As Kye (inventory manager) would say…

I’m glad that the saga is coming to an end. In hindsight, there could have been a couple of things we could have done and a few things we learned. One of them would have been to express ship a small batch from the original batch of parts to have them on hand as an emergency. Second would have been to get more visability on the status of the shipment. One of the problems was that on the system, it was showing that our stuff would be arriving on time, but that was because our operator was not updating the system. We needed to find info out about the shipments by calling or emailing directly. If we were aware of the delays earlier, we may have been able to react faster and make other arrangements.

Status of materials

Front and back feet

In our last update, we talked about parts that were expected to arrive on the week of March 7th. I’m happy to announce that these parts have now arrived and are being packed and assembled:

  • X, Y, Z gantries
  • Dust shoe brackets
  • Drag chain brackets
  • Dust shields
  • V-wheels
  • Cables
  • Assorted packaging
  • 3D printer filament
  • Inductive sensors

Here are the parts that we are still waiting on:

  • Power supplies (1-3 weeks)
  • Dust shoe boxes (this week)
  • Rail boxes (this week)

Production and assembly

We’ve been making good headway into production and assembly, and materials needed to ship the first batch of machines that we have on hand have now been pre-packed.

Future lead times

Once container MAGU5348230 arrives, we will have 1500 or more units worth of components for the LongMill MK2 12×30 and 30×30 with some exceptions. The two major parts that will be our next bottlenecks are likely to be the aluminum extrusion and the steel parts (gantries, drag chain mounts, feet). Both the rails and steel parts were made at 500 units worth, so we can make tweaks to these parts after the first batch.

Even with delays, sales have continued to be strong. We currently have around 400 units accounted for, and are expecting 500 units sold in the next couple of weeks.

Currently, another batch of rails is expected to ship in early June for another 500 units. We may be looking at extending lead times once we sell the first 500 LongMills as we may be waiting for the next batch of rails to arrive. Almag has been good at getting things shipped out on time or early so there is a chance we might get these parts earlier.

Steel parts are now starting production. We’ve given the go-ahead for some parts that don’t need changes, but we are expecting to finish the tweaks this week. Nithside, our manufacturer for the steel parts has told us that they are shooting to finish the batch this time within 3 weeks, as they were able to streamline some of their processes during the last batch. Total turnaround time with cutting, forming, and coating is expected to be around 6 weeks.

Once we are a bit further into the production, we’ll update our pages with new lead times.

LaserBeam

I talked with Ikenna about the status of the pending LaserBeam orders. We were able to ship some once we had more power cables arrive, but we are now waiting on copper heatsinks and power adapters to arrive to complete the production. The parts that we need for shipping are in container MAGU5348230, so we are facing the same delays as the power supplies for the LongMills.

We are currently producing and stockpiling parts and assemblies for the driver enclosure and shields, and we also have received another batch of laser goggles, fans, and lenses to cover for the next batch.

LongMill MK2 48×30 and Extension Kits

We’ve now received the:

  • T12 lead screws
  • 6001 Flange Bearings
  • T12 Delrin nuts
  • T12 ACME nuts
  • Longer drag chains

To get prepped for shipping, we still need to get:

  • Extension cables and wiring
  • Y gantry plates
  • MK1 to MK2 Delrin nut adapter

We just received our sample batch of extension cables. These will let our customers extend the length of the motor cables and inductive sensors. One they have been checked and tested, we’ll order a batch. We’ll also sell these on the store as extras so that customers can extend their cables if they need.

I’ve been using our 48×30 machine here and it’s been great! Currently, it’s just been used for general projects both large and small. Here’s a subwoofer box that I was working on for my car.

One thing I realized that was actually super handy about the 48in width was the fact that I didn’t need to cut any material down to fit the machine. All I did was put some half sheets of MDF that we had on hand, and just moved the mounting for the material down the middle, so I could just reposition the material to the area I wanted to cut.

I also put together a prototype machine for the MK1 to MK2 extension kits. At first I had a lot of issues with it, as it was getting stuck in travel, but it turned out that I had used a bad batch of prototype plates that had offset the bearing spacing by 3mm, causing the machine to bind. Replacing them has fixed the issue.

We are now starting to work with our beta testers to get the larger machines in their hands. The first two beta testers will receive their machines this week. Watch out for more news!

Everything you need to know about the AutoZero Touchplate

We’re excited to share a new product, the AutoZero Touchplate! This has been a long and complicated project that has been in progress for more than a year, with lots of design and manufacturing hurdles to get over.

Introducing the product

The AutoZero has one main purpose, to find the origin point of rectangular pieces of material. One of the main drawbacks of using conventional touch plates however is 1)the inability to use non-straight bits such as v-bits, tapered bits, and ball nose bits 2) needing to specify the size or diameter of the end mill you are using for the probing sequence.

Some higher-end touch plates can calculate the diameter of the bit to assist with probing by touching off the inner wall of the touch plate to find the distance traveled across two surfaces.

However, the AutoZero Touchplate is unique since it also offers a chamfered surface that allows the tip of v-bits, tapered bits, and ball nose bits to be used.

Lastly, we’ve made some general improvements to the new touch plates including:

  • Improved designs for touch plate wires, resulting in more reliable connection at the magnet and touch plate ends.
  • Nickel plating to help with conductivity and improved asthetic finish.
  • Integration with gSender, to make the set-up process super easy.
  • Cutout design to make removing the touchplate easy and to help visually confirm accuracy.

Pricing and availablilty

We now have around 600-700 units in stock and ready to ship. Pricing will be $120CAD/$95USD. Now to discuss the elephant in the room, these new touch plates are a lot more expensive than the original basic touch plate. There are a couple of reasons for this.

  • The cost to manufacture the touch plate itself is substantially more expensive
  • The product times for this item is very long and unpredictable
  • The AutoZero provides features not found on any other touchplates

In essence, the pricing decision for this product comes down to the fact that these are expensive to make and we can’t make a lot of them quickly.

To also make sure we’re transparent about our pricing, we’ve also compared our prices with some of our other competitors, and the pricing for this touch plate is in line with other high-end touch plates which lack the functionality of the AutoZero. In terms of a value standpoint, we believe that the AutoZero offers more than any other touch plate currently on the market.

We are hoping that we can continue to improve the design and manufacturing process of this product to bring prices down and make it more accessible to our customers. However, we feel that this pricepoint still allows us to be competitive and still provides enough profit for us to invest in research and development, as well as lowering the chance that we’ll run out of stuff (a common trend the past two years).

In terms of recommending this product, this is a very nice-to-have but absolutely not a need-to-have. The original touch plate offers a great value at $35CAD/$27USD, and has many of the same features and functionality as the AutoZero. The AutoZero is not needed for general use.

The engineering that has gone into creating this project

It’s safe to say that a lot of research, thought, and design went into this product. Here’s just a small peek at some of the things that we went through with creating the AutoZero.

Physical design and functional improvements

Here’s an excerpt from Chris’ design documentation:


Desired Functional Improvements for V2

There are many things that the current touch plate does well but there are possibly more features that we could integrate into a newer design while retaining the existing functions:

  1. Stabilizing the touch plate when placed on stock material before & during probing
    • This can be accomplished by moving the plate’s COM (center of mass) to be further overtop the stock material, placing more of the plate’s mass overtop the stock material, or increasing the coefficient of friction between the touch plate and the stock material
    • This creates a more reliable probing operation where the plate’s position is less affected by the movement of the wire harness, the small force imparted from the bit onto the plate during the probing procedure, or by other mishaps like the user grazing their hand past the plate before running the probe sequence
  2. Probing without the need to specify end mill diameter
    • Touching off two known surfaces rather than just one can allow for bit size compensation during probing, removing an extra step for the user
    • This can be done most easily by using a circular or square cutout or extrude
    • Need to ensure that enough wall contact exists to catch the mill flute at its greatest distance from its centerline
      • With our biggest mills being ¼” and having a helix angle of 30°, the largest span between peaks, P, would be = πD * atan(90-β) ≈ 16.13mm
      • The pitch on the ⅛” bits however is about = 8.17mm
      • Smaller ⅛” bits can have a cutting length of only 12-17mm so finding the right wall height to accommodate full contact on ¼” bits but not hitting the collet nut on ⅛” bits is a close game (collet nut furthest dia = 24.98mm)
  3. Probing non-straight-style cutting tools
    • This can include v-bits, round groove bits, and tapered bits (no straight edge bits)
    • Although these geometries can be unpredictable to probe, all these bits have a cutting edge that leads down to a singular conductive tip which we could leverage to locate their XYZ positions
    • Using a very shallow geometry, we should be able to make contact only with the tool tip while still being able to infer the XY location. V-bits would require a 45° minimum for 90° v-bits and below, but tapered and round groove bits would require and even shallower tangent geometry
    • Possible probing sequence
      • Touch the bit to a top surface to find the initial Z height 
      • Using the Z height and locating the bit near the shallow geometry, touch off the bit point in two X locations and two Y locations
      • Using these 5 probed coordinates, we can locate the zero point of the cutting piece
  4. Ability to measure angling in the stock material
    • Touching off at two or more points could allow us to compensate gcode to accommodate stock material which hasn’t be mounted square to the machine
  5. Coating the aluminum to avoid any future issues with corrosion or reduced conductivity
    • Openbuilds probe leverages 2µm nickel coating

Ideal design will maintain:

  • Thin profile to not reduce z-travel needed for probing
  • High side walls for straight bits
  • Low chamfered profile for tapers and Vs
  • Same starting point for all bits
  • Bit goes to zero point once probing is complete
  • Good weight and COM distance from material edge
  • Plate places to bit rather than bit placing to plate

Over 8 different design concepts were created before landing on the current design. Here are a couple examples.

  1. Hole block

    Rough dimensions: 60x60x20mm
    Total weight: 147g
    COM from edge: X & Y= 19.89mm
  2. Leaf plate

    Rough dimensions: 60x60x20mm
    Total weight: 127g
    COM from edge: X & Y= 20.12mm
  3. Hole block

    Rough dimensions: 80x80x20mm
    Total weight: 206g
    COM from edge: X & Y= 28.04mm

Manufacturing and supply chain challenges

The new design also proved to have some design challenges as well. First of the design challenges was in creating the chamfered edge. The AutoZero uses a 170 degree chamfer at the bottom of the plate. Initial prototypes used a ball nose based 3D toolpath strategy to create the angle, but because of the scalloping, the surface was not smooth and consistent enough for use with. This was then changed to custom tooling to create the edge.

The other challenge was to get consistent nickel plating thickness. Since we were working with fairly high tolerances, the thickness of the coating and the variance in thickness would impact the overall dimensions of the block. So this meant that the manufacturer would need to control the coating thickness AND the tolerance of the milled block underneath.

And lastly, even though these parts were shipped at the end of November/early December, due to lots of shipping delays, the touch plates finally arrived just a few days ago, meaning that the transit time for these were just about 4 months.

Talking about the Crafters, Machinists, and Woodworkers End Mill Sets

Hey everyone. I’m happy to announce that we’ve now created a couple of new end mill sets!

Order them here: https://sienci.com/product-category/cutting-tools/end-mill-sets/

So why did we create these new sets? Well, a common question our support staff has always been getting has been “what end mills should I get?” and we wanted to create something that would let folks try out a couple of different bits at a great price and cater to different types of users that call in.

Every set comes pre-packed with a number of bits and end mills that offer a great starting point for each type of person. We also offer between a 15-20% discount for each set compared to the cost of purchasing each bit individually. Because a large part of the cost of selling bits is in order picking and shipping, selling more bits in packs is more efficient for us and we pass along the savings to the customer.

Do you have any other sets you want to see in our store? Let us know in the comments or by contacting us!

Woodworkers End Mill Set ($60CAD/$47USD):

Each set comes with:

1/4″ Flat Upcut End Mill – 2D cutting, such as for borders of signs, making boxes, and other simple shapes

1/8″ Flat Upcut End Mill – 2D cutting on smaller projects, as well as lettering and shape cutting

1/8″ Ball Upcut End Mill – 3D reliefs, such as topographical maps and other simple curved shapes

60-Degree V-Bit – V-carving signs and letters, as well as chamfer cuts

1/4″ to 1/8″ Collet Adapter – Useful for adapting 1/8″ bits for routers that have a 1/4″ shank

This set is a great starting point for rudimentary CNC techniques like 2D cutting, lower detail 3D reliefs, and v-carving/engraving. We believe this is a great starting point for beginner users who want to get a taste of different CNCing techniques with a set of bits that are durable, versatile, and forgiving to mistakes.

Crafters End Mill Set ($75CAD/$60USD):

Each set comes with:

1/2″ Round Groove Bit – Bowl and tray cutting, for rounded bottom edges on their projects

1/4″ Compression Bit – 2D cutting on materials like plywood which are prone to splintering

1/8″ Tapered Ball End Mill – Advanced and high detail 3D relief cutting

1/16″ Flat Downcut End Mill – High detail letter cutting and general high detail 2D and 3D CNC projects

The focus of this set was to offer bits that we would consider “advanced” and require a bit more care and experience to set up the right feeds and speeds, but with the proper use, can create stunning results. We recommend this set to experienced users who want to try advanced techniques such as super high detail 3D reliefs, lettering, and micro-CNCing.

Machinists End Mill Set ($85CAD/$67USD):

Each set comes with:

1/8″ Single Flute Upcut End Mill – 2D cutting on aluminum and plastics

1/4″ Single Flute Upcut End Mill – 2D cutting on aluminum and plastics

1/8″ Makita RT0701 Precision Collet – The best option for holding 1/8″ bits on your Makita RT0701 routers

If you want to get cutting aluminum and plastics, this is an excellent set to get going. We recommend using single flute bits on CNC routers like the LongMill as they can produce the largest and biggest chips that help with heat and chip evacuation. This is critical for materials that are prone to melt.

March 2022 Production Update

Hey everyone, here’s the latest production update. For previous updates, please read our blog.

Folks doing projects and testing in the workshop

Materials are arriving

We’ve received a large number of materials over the last couple of weeks including some of the steel parts, power and USB cables, packaging, dust shoe parts, end mills, and more. We’ve made good progress doing the packing and processing, with most of the materials we’ve gotten in prepared for shipping once we receive everything.

We’re also expecting 3D printing filament, gantries, control boards, and other steel parts, and v-wheels to arrive any day now, as transport has been booked and are awaiting delivery this week.

Waiting on materials to arrive

We continue to wait on the shipment of power supplies for the LongMill and LaserBeam and other parts that arrived on Feb 13 at Prince Rupert. Due to rail congestions, we are still waiting on these parts to arrive. According to our updated tracking info, it is expected to arrive in the next two weeks. However, due to the uncertainty with when these parts will be moved onto rail, as well as potential transit time for truck freight from the Mississauga warehouse, we would advise customers that this shipment may not reach our shop until the end of the month.

We are frustrated with the delays in these shipments, as this shipment was expected to arrive at the end of January. We are hoping that these items will arrive soon, and in the meantime, we are doing our best to pre-pack as much as we can so that we can ship machines out as quickly as we can when they do.

By the end of this week, we are expecting to have all of the materials ready to ship the MK2s with the exception of the power supplies, which will be our biggest bottleneck.

Given these delays, for new orders placed today and onwards, customers should expect to receive their machines in April/May.

Packing progress

Rails ready to ship

We’ve been processing materials as they come in. Most of the day-to-day packing isn’t super interesting but we did make a small modification to the printers in our print farm that some folks might find interesting. With the new MK2 dust shoes, the height of the hose comes out to be around 196mm. Unfortunately, the printing height of the Prusa Minis we have in the farm, which make up the majority of the printers we have, only print up to 185mm. Initially, we printed the hoses on some of the other printers we have in the farm, we weren’t able to keep up with the number of hoses we needed to print. So, we had the brilliant idea to just make the Prusa Minis a little bit taller. After making a small simple spacer, we’re now able to print the dust shoe hoses on the Prusa Minis!

Now with 6 of our printers converted, we can now print up to 18 dust shoe hoses per day, meaning that we should be caught up with the printing in the next two to three weeks.

We’re also excited to get our 3KG filament spools to replace the 1KG spools, which means that we’ll be able to reduce the number of filament changeovers by 2/3rds, improving our printing efficiency and the amount of manpower it takes to run the farm.

Assembling dust shoe hoses

Dimensioned drawings are now updated for all LongMill MK2s.

We’ve now updated the dimensioned drawings for all of the LongMill MK2s to include the 48×30 as well as overall width and heights of the machine so that customers can prep their work areas, enclosures, and tables.

Wrapping up the instruction manual

Chris and Aleks have been hard at work making the new instruction manual and working with our staff and beta testers to perfect the assembly manual. We’re excited to share a final draft of the MK2 assembly instructions. Please note that there are still some minor updates that we need to make to finalize the manual, including making a compressed version (right now the PDF is 107MB large) and updating links for the add-ons, but we just wanted to share this with everyone to get thoughts and feedback, as well as people can get an idea on what the assembly process for the MK2s are going to look like.

LaserBeam production

New batches of drivers and other components are currently in production. We are experiencing delays with driver manufacturing as we need to adapt to component and chip shortages. Based on these supply chain issues, customers are advised to expect delays when ordering the LaserBeam. We are also waiting on power supplies and copper heatsink housing parts to arrive with the large shipment delayed in Prince Rupert to arrive to complete currently pending orders.

While we wait on parts to arrive, we’ve completed the wiring and have been assembling other parts, such as the air assist and driver housing components to prepare for the arrival of the parts.

We have pushed orders that were scheduled to ship end of Feburary to end of March, and we are advising a 8 week lead time for new orders.
