Lens Descriptions

Lens TypeDescription 
G2 Lens has the best efficiency (most power) and shortest focal length so it’s great for cutting and good for engraving 
3 Element Lens 3 Element has the cleanest beam profile (super detailed text, lines and image engraving)
G7 Lens has a good balance between the power of the G2 and the clean beam profile of the 3 Element.
G8 Lensis very similar to the G7 but it has a smaller focus length so you can engrave thicker material than the G8 because you would have more available Z axis travel. I will make a dedicated video for lenses but hopefully that gives you a bit of clarity until then.

June Production Updates

Hey everyone, this is our June production update. For previous production updates and other company news, please check our blog.

It’s continued to be a busy month for April, but as we talked a little bit in our previous update for April/May, we have continued to shorten our lead times. We’ve taken the time to train some of our staff on new responsibilities and reorganize and plan production for the coming months. We are near the end of our run of Batch 4 machines and are starting to prepare for shipping Batch 5 in June.

In terms of COVID, Ontario has slowly seen a decrease in cases and more of our staff are becoming vaccinated. We are fortunate to have had no cases so far, and hopefully none until the end of the pandemic.

blank
A new batch of motors, lead screws, and drag chains

Lead Times

Lead times are expected to average around 1-2 weeks for this month, however we are starting to face shortages in parts that will rely on the timely arrival to keep up with production. Some of these parts include:

  • E-stops
  • Touch plates
  • Arduinos
  • Delrin V-wheels

We expect these parts to arrive in 1-2 weeks. However, this may change if we face delays in transit. We will keep lead times updated on the product page to account for these changes.

Supply Chain

There have been some minor bumps along the way in terms of supply chain especially due to current worldwide events, but luckily with early planning and dedication from the manufacturers we work with, the supply chain process for Batch 5 has been relatively smooth.

One area that we’ve seen a large spike in prices have been with drivers and Arduinos. Due to the chip shortage, many of the components that go into the LongBoard controller have gone up in price. Most ICs that go into this production have doubled in price, and new products that we are working on that involve chips may be delayed due to the unavailability of chips. We have acquired parts for the next 500 controllers with approximately another 100 controllers in stock, but we may need to be cautious of continuing shortages for the rest of 2021.

On the topic of spiking prices, steel prices have gone up more than double since the start of the pandemic, affecting the price of gantries and other steel components that go into making the LongMill. On a lesser level, copper, tungsten carbide, and other raw materials have increased overall prices for many components as well such as E-stops and end mills. Cardboard shortages with our packaging manufacturer have also affected costs and lead times a few times over the last few months too.

Luckily due to improving processes and increasing batch sizes, we have been able to find other ways to save costs and so we don’t expect to have major changes in pricing for our products, however, it is a reality that we may need to face at some point that our company will have to account for changing material prices by increasing the prices of our products.

We have also been affected by the shipping fiascos that have been happening around the world as well. Although we weren’t directly involved in the Suez Canal crisis, we have experienced slowdown in some shipments due to this situation. At the time of writing, most of the parts that we need for Batch 5 production are in transit within Canada (by rail) or are in production with local manufacturers. A couple of parts that we are still waiting on that are in transit by sea include:

  • Router mounts
  • Couplers
  • Delrin nuts
  • 3D printer filament

The remaining components for Batch 5 are expected to arrive this month but won’t be complete for shipping until these parts arrive.

Manufacturing

There have been a few changes in manufacturing at Sienci Labs. Here are some of the things that have been going on.

One small change is the material that we have made the ACME nuts from, switching from stainless steel to brass. Brass has shown to be easier to work with in terms of manufacturing and forming threads. In previous manufacturing batches, a portion of nuts were rejected due to rough threading that made it difficult to thread onto the lead screws. The new brass nuts are of much better quality.

blank

As part of the transition from steel shoulder brackets and drag chain mounts, Batch 5 kits will use M8-16mm bolts instead of M8-25mm bolts to mount these parts. There is no functional change, as the longer bolts are a carryover from when longer bolts were needed on the 3D printed parts.

Next, we are switching to e-coating our gantries from powder coating. We believe that e-coating is an excellent alternative to powder coating as it provides a cleaner, more consistent surface which is important for our XZ gantry assemblies. In some of our recent batches of powder-coated steel, we were running into issues where paint contamination and dripping would either produce cosmetic defects or affect the assembly of the parts because of the unevenness of the surface. E-coating does have a thinner surface, which theoretically means that it offers less scratch resistance on parts. However, based on samples that we have been provided of our parts after being e-coated, we have seen significantly better resistance to chipping and surface quality, without much difference in scratch resistance. This change should decrease manufacturing costs while improving overall quality.

blank

In the last batch, we switched to using M3 screws with captive washers to help keep the screws from coming loose. For these screws, we have switched from stainless steel screws to Class 12.9 alloy, which is a much stronger screw that will prevent head stripping. Head stripping has been a minor inconvenience as removing stripped screws takes a while.

We’ve added three new CR30s (3D Print Mills), a belt based 3D printer. These machines will add additional 3D printing capacity with the benefit of being able to continually print repeated parts. We are currently in the stage of testing and tuning these machines, but we expect each printer to do the work of 4 standard 3D printers, increasing our print capacity by approximately 25%.

blank

Design

Batch 5 comes with some very minor design changes to the LongMill.

First to mention is that motor shafts on the X and Y will be fully round. This is due to a very small number of customers reporting their motor shafts breaking off. The engineers at LDO Motors and us have confirmed that the full shafts will prevent this.

blank

We are manufacturing a slightly modified 65mm router mount to eliminate the need to use M5-12mm screws. Because of the drill tap depth of the four mounting screws in the back of the router, shorter M5 screws were needed compared to the rest of the machine assembly. With the new router mounts, M5-25mm screws can be used on all parts of the router mount. We have also relocated the additional tapped holes that are used for mounting to the front of the mount for easier installation of accessories such as the LaserBeam.

blank

New ACME Delrin nuts have been manufactured without the counterbore, which were an unnecessary feature for our application.

Shipping

Shipping to US and Canada have been reliable overall and seems to have returned to pre-COVID speeds.

We had some delays with Canada Post shipments going to the US via US Air Parcel, so as an alternative we would recommend using UPS.

We have had several issues with customs for shipments going to Mexico this past month that are new. If you have an order that needs to go to Mexico, please let us know in case we need to make other arrangements.

What is a G-Code Sender or CNC Machine Interface?

Hey everyone. We get a lot of questions about software for CNC machines, part of which includes using a g-code sender or machine interface. If you’ve ever gotten technical support from us, there’s a good chance you might have talked to Kelly, who took some time to make this video to help answer the common questions and discuss common functionality in the software.

This video covers some of the basic features that are in g-code senders like UGS and our very own gSender.

gSender Surfacing Tool now available

gSender downloads are now public. Find downloads here: https://sienci.com/gsender/

Our development team have been working hard to continue making gSender better. Our latest update improves overall performance and reliability, as well as working on new features. The latest version now comes with a surfacing tool that makes it easy to surface your wasteboard using the built in tool.

blank

This tool lets you import your basic settings such as your tool size and speed to automatically generate the toolpaths to run on your machine. Not only can you use this to surface your machine, but you can also use it to surface other stock by changing the size on the tool.

If you aren’t on the latest version of gSender, your gSender program will have a green arrow to indicate an update is available on the upper left side where the gSender logo is.

Additional gSender Documentation continues to be in development. Feel free to check it out to learn more. Continue to stay tuned as more changes and updates come to gSender!

gSender BETA Public release is here!

blank

Hello all,

This is a really big milestone that I’m really excited to have reached! It’s not easy or inexpensive to be paying nearly 4 peoples salaries for coming up on 5 months just to develop a program that is being made available for free but we just really think that this labour of love is going to be something that benefits not just the LongMill community but the Hobby CNC community at large.

So I guess now is the time for me to answer the two big questions:

  1. Why now?
    Though the changes between our release last week and this week aren’t drastic it’s never really clear cut when something is ready to move onward. Since this was my call, I can say that I didn’t want to make gSender public until I was sure that we had all our bases covered. This included at least a couple of iterations on builds for every OS, less reports of crashing and bugs, fulfillment of the big-ticket item requests like jogging stability and keymapping, and some refinement in the overall design that was more of a gut feeling.
  2. How does this include the hobby CNC community as a whole?
    If you weren’t aware, the LongMill and many other machines such as: X-carve, Shapeoko, Bob’s. MillRight, OpenBuilds, 3018 CNCs, and more all run on the GRBL open-source firmware. This is what gSender has been built to support. This means that though gSender comes ready out-of-the-box to run a LongMill, it can also readily support many other kinds of CNCs and we’ve made it open-source and free across the board so that anyone can come on over, grab it, use it, and benefit from it. So yeah, tell your friends! No mater what CNC they use, if you’ve enjoyed using gSender then they probably will too 🙂

Alright so, of course I’ll do a quick recap of changes since the previous release and where to download, I just want to say a couple last things first:

  • With gSender now public, this will likely be one of the last communications made to this mailing list as all of you signed up for the duration of the closed Beta which is now concluding. Instead, I’ll likely be moving my communications over to a combination of our website blog and the Forum – we’ve got the regular Sienci Mailing list you can feel free to sign up for if you want to continue receiving development notifications
  • If you’ve enjoyed using gSender, I’d love it if you would take the time to respond back a review of how you find it. I don’t yet have a plan on how I’m going to use the reviews but at the least me and my dev team really grin ear-to-ear when we see you guys getting so much out of gSender so that would be some great feedback to hear
  • Lastly, thank you all so much for taking the time to provide your feedback – the feedback that’s brought gSender to what it is today. There will continue to be a page available for submitting gSender feedback here: https://sienci.com/gsender-feedback/ so keep it coming if you have more to say. I’m so grateful for the time and words from all of you

Okay, on to the normal stuff!

New changes:

  • Improvements to job handling
  • Tooltips created for data entry points
  • Splashscreen tweaks
  • Working PI build!?

Downloads:
All downloads are now available on the gSender page on our website, check them out here!
https://sienci.com/gsender/

There’s also now a documentation page underway, check out the beginnings of it here: https://sienci.com/gsender-documentation/

If anyone has any further questions or need assistance downloading the new version I’ll be keeping my ear to my inbox and the gSender forum category over the weekend 

👍

Cheers cheers cheers!

Talking about the Makita RT0701. Do I need a larger router for my CNC?

I decided to write this post to talk a bit about routers to use on hobby CNC machines like the LongMill. If you’ve done some research on this topic, you’ve probably seen a lot of machines use the same Makita router. Of course this isn’t a coincidence. We believe that the Makita RT0701 is a great option for a lot of reasons, including:

  • Good speed control from 10,000 to 30,000RPM
  • Simple round body which makes it easy to mount to a machine
  • Affordable price of around $100 to $150
  • Easy to find at most big box hardware stores
  • Ample power and performance

However, for a lot of people, especially woodworkers who use full size routers that have 1/2″ shanks and +2HP motors in their work , the Makita router looks a little bit dinky. If you’re one of those people who have this opinion, here are the reasons why the this router is more powerful than you might think.

Electronic speed control

By far the biggest reason the Makita punches above its weight is because of the electronic speed control built into the router. Simply put, when the Makita’s motor is under load, the electronics will boost power to the motor to compensate. This means that no matter how hard you’re pushing the router, the motor will continue to spin at a constant speed. For CNCing applications, this is an important feature as the speed of your router is closely tied with the speed and quality of your cut.

Although many routers now come with this feature, routers that do not have electronic speed control need to rely on their internal inertia to keep their RPMs stable. Although this works in an hand held application, CNC machines need to have a consistent speed through all of the cuts for the best results.

If you have a router that doesn’t have speed control, you’ll likely notice that your RPMs drop when you hit the material, and you have to adjust the pressure of your cut to keep cutting consistently. With a router like the Makita, the router will instantly compensate for the change in load and not allow the RPMs to drop.

Matching the performance of your router to the performance of the machine

With almost all hobby CNCs, the deflection of the structure of the machine is the limiting factor. To put simply, the machine will deflect far enough to ruin a cut before the router will begin to struggle to keep up, which means that there is no point in putting a larger router that will never see its full potential.

Our real life testing

Over the last couple years, we’ve heavily abused our Makita routers, such as by cutting large amounts of aluminum and wood at a time. We do run tests as well that involve crashing the machines while the Makita is still running to test the effects of changes in the electronics which can completely stall the router. We also have built custom industrial-focused machines that use the same router. Here’s an example of a project where we used a Makita router to cut aluminum.

Some of our tests include cutting through upwards of half an inch of hardwood using our 22mm surfacing bits to stall the router.

I hope this post provides a bit more confidence in the Makita routers and answers some questions on whether a larger router is needed for the LongMill.

Laser Pre-Order: May 14th 2021

Hey everyone, Ikenna here again for another laser update. Since my last update I have been testing supplier parts, finalizing our first PCB designs, testing suppliers and ordering parts for production. 

Designs:

  • Copper Heatsink: Design is finalized and sent to the manufacturer 
  • Aluminum Heatsink: Design is finalized and sent to the manufacturer
  • Lens Focus Ring: Design is finalized and sent to the manufacturer
  • Air Assist: I have updated the design but more fit testing is needed 
  • T-mount: Design is completed, if there is time I will redesign a magnetic mount
  • Laser Driver: I have our first 2 pcb driver designs. Will be ordering assembled prototypes this week
  • Laser Driver Enclosure: Now that I have a few pcb designs, I will begin designing an enclosure

blank

Supplier Testing:

  • Safety Goggles:Testing safety goggles is complete and I will be looking to place an order in the next week.  
    • To summarize the testing procedure: I used a laser power meter to measure optical power and then ran the same test with the safety goggle lens between the laser power meter and the laser. This effectively tested how much optical power made it through each lens of the safety goggle. Although most suppliers kept it under the FDA recommended limit of 5mw, there was one supplier that stood out. 

blank

  • Lenses: I have narrowed it down to 2 suppliers, will have a supplier selected by the end of this week
  • Fans: I have tested our fan supplier and am happy with the results. Our main fan selection needs more testing to find the perfect noise output to heat exhausting balance. Trying to make sure the main fan we select isn’t noisier than it has to be. 
  • Power supply: I am finalizing the connector type that is needed for the power supply. Will have samples ordered and tested next.  

blank

Supply Chain:

  • Laser Diodes: We placed our first order of diodes this week. I will continue to look for backup suppliers so that we can keep up with any future demand if needed.  
  • Aluminum Heatsink: Order has been placed for our very own aluminum heatsink design  
  • Copper Heatsink: Order has been placed for our very own copper heatsink design
  • Lens Focus Ring: Order has been placed for our very own lens focus ring design

Pre Order Launch: 

Our Pre order page will launch May 14th, price is set to $400CAD for the module + $60CAD for the safety goggles. Each laser will include 1 lens with the option to purchase more. Here are some of the things we still have to finalize: 

  1. Photorealistic product renders
  2. Finalizing a product name 
  3. Introductory resources so you may begin preparing to operate your laser module.

Just like this update, all future laser updates will be sent out directly to the mailing list as well as posted publicly to the Sienci blog & Facebook group

April/May Production Updates

Hi everyone, this is our April pt 2. and May production update.

If you’re looking to order a machine or waiting on one to show up, please read this update to find out what’s going on in our shop.

For previous production updates, please check our blog (https://sienci.com/blog/).

If you are looking for an update on where your order is on the waiting list, please check our list (https://forum.sienci.com/t/list-of-shipped-machines/1215)

Lead times for new orders

We’re happy to announce that lead times will be dropping from 3-5 weeks to 2-3 weeks!

*UPDATE – We have now cleared our backorder. New orders will ship within one week!*

This comes due to a flattening out in the number of orders we are getting, as well as the additional staff that we’ve brought on to continue packing and shipping machines. We are aiming to keep our lead times within two weeks, however, we are stating our lead time as 2-3 weeks to provide ourselves an additional 2-week buffer for any unforeseeable delays.

It’s exciting to finally get back down to our 2-3 week lead time, as we have seen a major backlog of orders since around June of last year and it wouldn’t have been possible without the hard work and dedication of the Sienci Labs team. As our production capacity meets the demand for the LongMill, this gives us the opportunity to dedicate more time to developing other parts of the company such as marketing, customer support, and technical development. We also expect to see improvements in the productivity and efficiency of our production, giving us more flexibility in the number of machines we can sell and ship.

At the time of writing, we have around 270 machines in stock. We expect to keep our lead times at around 2 weeks until we run out of this stock.

Batch 5 production

We are currently shipping machines for Batch 4 and are producing parts for Batch 5. Parts for Batch 5 will be arriving between May and June. Once we run out of parts for Batch 4, new customers will need to wait for all of the parts in Batch 5 to arrive for us to start shipping again.

Batch 5 will consist of 1000 LongMills.

Commonly asked questions

If you are interested in ordering a LongMill please read this section.

If I place an order today, how long will it take to ship?

2-4 weeks

Is there any way to skip the line/get my machine faster?

  • No. To keep things fair for all of our customers, we ship all orders based on when they were ordered. There are no exceptions. The only way to get a machine faster is to order one sooner. If we have updates to the lead time, they will be posted here and on the forum: https://forum.sienci.com/t/list-of-shipped-machines/1215If you want to see where you are in the queue for your order, please check the forum.

Does it make a difference in when I get my machine if I pick it up?

  • The only difference it will make will be that you will not have to wait for the shipping/transit time for the machine to ship. Typically, machines take around 1-3 days to ship within Ontario. Otherwise, there is no difference.

When do you charge my card/take payment for my order?

  • Your card will be charged at the time you place your order. This is to ensure your place in line, purchase parts ahead of time, and have the most accurate estimates on production and delivery.

How can I cancel my order?

  • You can cancel your order with no penalty any time before your order ships. Please contact us through our website or email us with your order number and a request to make a cancellation. A refund will be processed through your original method of payment.

Can I add other items to my order before it ships?

If you’ve ordered a LongMill and wish to add other items to your order afterwards before it ships, please choose “Local pickup” (for free shipping) and add your LongMill order number. Some items (such as the T-track sets) cannot be combined for shipping.

200 Review Milestone for the LongMill

When we first launched the LongMill on our website, Chris set up a system to let people post reviews about the LongMill. These reviews have been important to us so that we can continually collect feedback and have real-world testimonials from our customers on how they feel about the machine.

With both me and Chris having used CNC machines for a long time now, one of the things that we’re always conscious of is how we can relate to our customers that are using CNC machines for the first time. The review system has been one way we can keep in touch with customers and their feedback as they journey into the realm of CNCing.

The review system of course helps share real experiences that LongMill users have had so that they can recommend to other customers on whether they should get a LongMill or not. We send an email to users roughly two months after purchasing a LongMill to ask about their experience with Sienci Labs and their machine to make sure that they’ve had enough time to get to know their purchase.

blank

Here are some reoccurring positive points people have made in the reviews:

  • Excellent customer service
  • Price and value for money
  • Easy to assemble
  • Overall machine performance, quality, and rigidity

Here are some areas we could improve:

  • Missing parts and improving QA
  • Improving software support

Thank you for everyone who’s written a review for us. Your positive comments and support have been a great morale booster for us and the rest of the team!

Laser Development Update

Hey everyone, Ikenna here. Wanted to offer everyone a new update on the laser attachment and the progress on the development. I can break down what I’ve been doing into a few categories; design, samples and testing. 

Designs:

  • Copper Heatsink: Main design is completed, may make minor changes to offer better component fit.
  • Aluminum Heatsink: Main design is completed, may make minor changes to offer better component fit .
  • Lens Focus Ring: Main design is completed, testing fit with resin 3D printer before getting samples made.
  • Air Assist: Rough design is completed, will need to make major changes once heatsinks are finalized.
  • T-mount: Design is completed, if there is time I will redesign a magnetic mount.
  • Laser Driver: I have 2 PCB designers working on a laser driver design as we speak.

Samples:

  • Safety Goggles: I currently have samples from 3 different suppliers, I will test each one to ensure we are getting the optical density I need to ensure safe laser operation. Once I know which suppliers have the best quality safety goggles, we will place an order for a few hundred. 
  • Lenses: I currently have 3 sets of lenses from 3 different suppliers, I will test each one to ensure we are getting the best lens quality when compared to reputable North American lens suppliers. 
  • Fans: I have a sample set of fans from a very reputable overseas supplier being shipped this week. I am confident this fan supplier will provide high quality parts but if that is not the case, I’m in contact with a few other suppliers that I can work with. 

Testing: 

  • Software: Lightburn has been my software of choice, very simple, lots of features and reasonably priced. I will also begin using LaserGRBL for testing as it is a free option for customers and I’d like to be able to help with any issues that may arise with these 2 software options.
  • Laser Diode: I have been testing the quality of a particular 7W diode and am very pleased so far. I have been keeping current low when running tests but I will be running tests at full power going forward
  • Functionality: Currently I’ve been using mix parts from Amazon and North American laser suppliers as a proof of concept but as I get more into the supply chain the goal is to have a prototype that uses all parts from our final list of suppliers.
