Hey guys, here are our September 2024 production updates!

AltMill

In August we received a lot of parts for building the AltMill. We’ve done a lot to continue ramping production up including:

• Building new carts and jigs to help with moving materials around and helping with assembly
• A much bigger and more stable tapping setup

We also ran into a few new issues:

• We found a number of the rail extrusions to be bent enough to have uneven machining. We do have enough for the time being to continue shipping, but we will have to make more to make up for the bad parts. We are currently in production for another batch of rails, so we are adding more rails to the new batch to make up for the bad ones.
• Over-sensitivity of closed-loop stepper motors and default acceleration settings, especially on the Z-axis causing false alarms for the first 50 AltMills. Updates to the firmware settings, which should be found now in the latest version of gSender adjust microstepping defaults, and any other outgoing AltMills have this issue already fixed.

In other news, we built a 2x4ft working area AltMill with some spare parts. It’s mostly for internal use so that we can do testing, but we suspect a lot of people are going to be interested in a slightly smaller AltMill as well. If you’re interested in this form factor, feel free to let us know!

We’ve also started making the assembly videos for the AltMill. We did the filming in the third week of August, and we expect to have videos coming out sometime in September.

We now have about 100 AltMills shipped, and we expect to ship another 50-100 in September and October. We should also be getting our Batch 2 AltMill parts in the next 2 months as well, so we expect to continue scaling production.

LongMill

LongMills continue to ship out smoothly, with most orders shipping out within a week.

One main update to share is with the T12 Spring Loaded Anti-Backlash Nut Blocks. We’ve initially made them from injection moulded blanks which were machined after, however, we found out that due to internal stresses, the threading would be inconsistent and require additional processing to machine properly.

We’ve now started machining them from cast blocks, which have lower internal stresses, which means that there is little to no deformation and changes to the overall shape of the blocks after threading. This method is more expensive, but improves the quality, saves time in re-machining, and reduces the number of rejected parts, which we believe is worth the tradeoff. Due to the time savings and other benefits, there is a good chance we’ll switch completely over to the new blocks and scrap most of the old ones that haven’t been QA’d.

Due to some variability in the tightness of the blocks, we’ve advised users to do a bit of break-in before starting their job. Our expectation for the new blocks will be that this break-in will not be necessary and we will be able to have much more consistency in the resistance in the blocks. We have completed testing for the new blocks and expect blocks to transition into production any day.

Vortex and LaserBeam

Both Vortex and LaserBeam orders are shipping out as usual.

Ikenna and Jen are currently working on new resources for LaserBeam and SuperLongBoard to bring new features and details on improvements and setup, so make sure to keep an eye out for that.

LaserBeam Livestreams are also coming to an end after 2 years of consistent episodes! Congrats to Ikenna and the team for running these livestreams.

More livestreams and content to come out soon with the UltraBeam, so keep an eye out for that.

One big update for the Vortex is that we are finalizing details for a close-loop Vortex kit that allows for full 4th-axis support. That means you’ll be able to control all of the axis (X, Y, and Z), plus the rotary (A) axis simultaneously. This is one of the big features we’ve been working on gSender and SLB for.

Please keep an eye out for news in the next few weeks!

Spindles

We have received another batch of 50 spindles which have been allocated for shipping AltMills. We currently have another 350 spindles on the way, but they are currently delayed in shipping. At the current timeline, we expect the spindles to arrive in the third week of September. Once those are received, we should be shipping the LongMill Spindle Kits shortly after.

If you’re interested in learning a bit more about spindle and router testing, make sure to check out our video here

We’ve also been experimenting with different size/voltage spindles since we know that the AltMill can handle more power. We’ve of course started with the 1.5KW 110V option since it makes things accessible for the typical hobbyist, we wanted to know where the limits of the AltMill are in case we start getting users that are more industrial or production-focused.

Here’s some testing with a 220V 4.5KW spindle.

It is important to point out that for most people, 1.5KW is still more than enough power for how fast hobbyists are comfortable pushing their machines, and the spindle is more than able to handle anything you throw at it if you slow down the machine to accommodate. Additionally, the 1.5KW spindle is the only option that can run safely on 110V power that comes out of your wall. Larger spindles will require higher voltage (220V) power.

I should also note that while we still recommend getting our AltMill Spindle and Dust Shoe Kit with your AltMill since it’s plug-and-play and will get you set up quickly, you can still also buy other spindles to put on yourself.

At least from our observations, we haven’t seen hobby users fully push the AltMill to its limit. However, we believe that people looking at the AltMill for industrial applications might be interested in a bigger, more powerful spindle, especially if they have power available in their shop.

Sprouter

We’ve continued to work on this project this past month. We are continuing to test:

• Bearing longevity and performance in different configurations
• Heat management
• Sound and motor tuning

We feel pretty confident in our motor design and construction. However, we’re still left with another frontier to tackle, which is the driver. Having a good driver is important as it allows us to properly and accurately control the speed, improve motor efficiency which in turn reduces heat, and makes the motor quieter.

We have been testing and working with the Chinese manufacturers of the motors to provide us with their drivers. However, while they are close to the performance we are looking for, they still lack the overall performance and speed control precision we want. We will continue to do testing and iron out as much as we can with these drivers, however, we are taking another approach of developing our own drivers.

Here are some pros and cons of going down this path.

• Developing our own drivers means we can tune and perfect every aspect of it. However, we require more advanced hardware and computing on board which adds to the cost.
• Some drivers are already safety certified since they are already used in different applications. Developing our own means we need to do the safety certification, which costs time and money. However, overall, a custom driver will likely be safer since we can use additional safety features like current control and stall detection to stop the device when there are issues.

We also have a first look of PWM control of the Makita router clone!

We are now working on next steps to figuring out ordering and production for the first batch so we can prepare for a launch near the end of the year.

gControl Panel computer

After a lot of digging, we’ve figured out a couple things with the Windows licensing.

• Our computer hardware can run Windows 11 Home and Pro, but it is very difficult for us to get it at a price better than retail.
• Different licenses are needed for different regions, which means that we need to differentiate between computers shipped to different countries.
• An alternative OS is Windows 11 IOT, which is a version of Windows 11 that focuses on systems that require high levels of stability and used in specific applications. For example, they are used in bank ATMs, kiosks, and industrial machines.

As described on the Microsoft Website:

Windows 11 IoT Enterprise LTSC is intended for fixed-function, special-purpose devices that require a long support lifecycle of 10 years. These devices are typically found in industries including banking, quick-service restaurants, healthcare, hospitality, manufacturing, and retail.

Windows IoT Enterprise LTSC is based on the same foundation as Windows Professional and Windows Enterprise, delivering the same compatibility, security and management capabilities required for commercial deployments. Windows 11 IoT Enterprise LTSC provides additional capabilities to lockdown the device experience for public facing or employee facing scenarios along with the ability to customize the operating system footprint.

Windows 11 IoT Enterprise LTSC is available for both x64 and ARM64 architecture.

For more information, see Windows 11 IoT Enterprise LTSC Evaluation.

This is great, because, while a retail Windows 11 Home or Pro license costs over $100, the IOT license is around $35USD. Additionally, these computers can be deployed around the world without the same restrictions as a retail license.

I feel that Windows 11 IOT also aligns with the use case of why we want to offer our own PC solution, which is to improve reliability of the CNC system overall, and reducing the number of variables effecting the reliability of the system is an important way of doing so.

We have those first 50 computers in production now, and are expecting them be ready to ship to customers in late October/early November. More details to come. Depending on popularity and interest, we’ll scale up production for a larger batch shortly after.

Hey guys, another busy month here for Sienci Labs. Here’s some news to share.

AltMill

We continued to ship machines out in July and we are excited to see people putting their machines together. Our first 50 or so folks should have received their machines and we are expecting to start shipping another 50 units at the start of August. The remaining parts for another 100 units will arrive around the end of August so that we can wrap up the first batch in September. As we typically do in these situations, we are full bore on the assembly of subcomponents, and we will be able to ship things rapidly once everything arrives.

While overall things went smoothly, there were a number of things we needed to improve on and change, or make adjustments to the manufacturing process as we continue to work towards starting shipping for the next 150 machines.

• A number of shipments arrived damaged and we have continually improved the packaging for the AltMill to address these issues. Since we did anticipate some issues to come up when we first start shipping, we’ve staggered some of the shipments to allow us to make sure we are able to fix things as we go along.
• We did also miss shipping the dust shields with the first 13 or so AltMills, which we’ve shipped out as soon as we found out.
• There are a number of improvements to quality we’ve addressed, such as the height of the bearing blocks, threading on the extrusions, and surface finish of some of the parts. These issues were manually fixed for the first 50 machines, of course, but additional QA checks and instructions have been passed down to manufacturers to have taken care of in the future batches.

Besides some of the issues, we’re glad to start getting positive feedback on the ease of assembly and overall quality and construction of the AltMill, and we believe that we will continue to improve this product in all aspects. Thank you to the first group of people who have provided us feedback and support!

Additionally, Batch 2 AltMills are now starting production. We are in the process of ordering 200 sets of parts for large components like extrusions and plates, and 400 sets of parts for smaller components, such as fasteners, bearing blocks, brackets, and couplers.

In other news, are working on a few more things including:

• Having replacement parts like bearings and linear guides up for sale on the store page
• Additional documentation for accessories, such as the dust shoe and Vortex
• Assembly video for the AltMill

LongMill MK2.5

LongMill MK2.5 pending orders have been caught up and new orders should ship within 1-2 weeks. We are now in Batch 9, with 1500 machines, which should keep us stocked for at least the next 4-6 months.

LongMill Spindle and Dust Shoe Kit

Due to the massive amount of interest from the LongMill community, we have now created a specific LongMill Spindle and Dust Shoe Kit! For those who might have already ordered one, the hardware is the same as the AltMill Spindle and Dust Shoe Kit, but with a 80mm router mount. You can find the kit on our store page.

These kits are coming with the AltMill Spindle and Dust Shoe Kits that are coming with Batch 1 and Batch 2 AltMills, and are expected to start shipping at the end of August or early September.

As with everything, we’ve done a lot of testing and research to make sure not only are we able to make sure that the kit is suitable for LongMill users but also to share testing data and our assessment. To read the full article, please check out our blog post.

Sprouter/Makita Router Clone/Spindles

We received another brushless DC motor sample to start another batch of testing. However, we have run into some minor issues and working on a few things such as:

• Making a new batch of motor and bearing mounts
• Improving the plastic sleeving for the motor

There still appear to be some speed-tuning issues we’re still trying to iron out. Development on the BLDC system continues to be a bit of a slow slog as we continue to work with and vet 2-3 different manufacturers.

We have some promising results with the Makita clone. Just for some context:

• We wanted to explore the option of selling our own version of the brushed AC router that other companies currently sell, like the Carbide Compact Router or the Openbuilds RoutER, and started talking with some companies that make them.
• We had done some testing on similar products in the past, as well as a deep dive into the construction of the Makita RT0701 and found some areas that we could improve.
• We could add a few features, such as using an ER collet system, better bearings, and PWM control

We have found that the overall power and speed control performance is acceptable and on-par with the RT0701.

Our next steps from here include:

• Creating a system for 5V input and a switch between manual and PWM control
• Safety and regulatory certification

Panel computer

I’ve been using one of the new panel computers and to this point, they have been fantastic. With regards to the hardware, they are solid and easy to work with. We’ve also tested a number of monitor mounts and designs and have settled on a pretty stable set up that should work well for LongMill and AltMill users.

Our main problem continues to be with trying to sort of a way to get access to Windows 11 licenses. Here’s a few things we’ve learned:

• There are a number of different types of Windows licenses. The one we want needs to allow us to install Windows on the customer’s behalf as a OEM or manufacturer. This means developing a relationship with Microsoft to set up an account. Even though we’ve tried, there doesn’t seem to be a straightforward way to make that happen since we’re way too small of a company it seems.
• As another way to do this, we’re in the process of talking with some solutions providers that partner with companies like Microsoft to implement IT solutions.
• Additionally, we’ve talked with some other, perhaps better known computer manufacturers that can sell us a similar type of touch screen computer.
• There are also some secondary markets for licenses that sell online for a reasonable cost. However, based on our research, buying from these sources do create some risks, such as the licenses stopping working after a while or arbitraged from countries that might not allow the licenses to be used in certain markets or North America. It is still an option to use this, but we are aware that there may be some risks and we are considering our first options as there are less risk of licensing issues.
