This past July was a busy month. Here are August 2025 Production Updates!
AltMill 2×4 and 4×4
Probably the biggest news of the month: we had our batch of materials we were waiting on to continue shipping on time. It’s sort of funny how we talk about when a shipment is on schedule, because we’re so used to things being late, we say it’s “on time”. This is why were letting people know that there was a good chance that we would have to start shipping in August. However, given that all the materials came in July, we have already started shipping and customers may be seeing their machines a few weeks earlier starting July 11th. Over the last three weeks we’ve hit about a hundred machines shipping out per week.
Additionally, we have reduced our lead times down to around 5-7 weeks, and we’re expecting lead times to continue go down gradually as we clear the queue. If we’re on track with our shipping rates, we should get there at the end of August and for us to complete Batch 5 in the first week of October.
We’ve brought a few extra staff members and have continued to hire more people for production to prep materials to get out the door. Batch 6 production is now underway, with parts completing in October as well, hopefully in time for when we run out of parts in the previous batch.

We also recognize that we do have a couple housekeeping things that we need to tackle, including more resources for the AltMill maintenance and offering replacement parts on the store. Our team is continuing to work on that, especially as we continue to grow our community.
In other news, Mike has set up some automation in the print farm to help print the dust shoe parts with a little less human intervention. We’re currently working on the injection molded version to soon take over 3D printed shoes, but we expect the manufacturing process to take another few months to complete.
AltMill 4×8
Version 1 of the AltMill 4×8 was constructed this past month. This was to get a general idea of scale, assembly, and everything that we can’t from 3D modelling it on the computer. We took parts from the original AltMill 4×4 to build this prototype. We’re expecting to start testing the full machine in the next week or so. We’ll post some testing and project videos showing the new machine soon.
While the X axis of the AltMill 4×8 will be more or less the same as the 4×4, version 2 and the final version of the 4×8 will use different Y axis rails to support the rack and pinion hardware. Another set of dies and extrusions are being produced now and we are expecting these to be arriving sometime at the end of August. We also have some of the production version parts on order so that we can have potentially a small beta testing run before going into full production to iron out any bugs. Based on our current timelines, we should have these around the end of September.
We are also starting to work on how big our batches are going to be, since we’re expecting a lot of interest. However, we’re already quite packed in our current production space, so there’ll have to be a bit of extra planning involved.


AutoSpin T1
Due to some issues with working with our supplier, we are not certain of what direction we will be taking this project. Over the last few months working with this supplier, we had some general small communication issues, however, we ran into an issue with the the way the router was certified. One of the key aspects of the design is the control cable and electronics to allow CNC controllers to control the speed of the router. However, in the official certification documents, this was not included. From our perspective, this is a critical part of the product, and without this part included in the certification, we open ourselves up to additional liability.
There are a couple of ways forward from here:
- Let the current supplier properly certify with the correct specifications
- Find a new supplier to work with
- Put the project on the backburner
We’re still going back and forth with the supplier to determine how we want to move forward, but we expect the project to be delayed until we get this part back on track.
New (Larger) Bits Coming Soon
With the growing community of AltMill users, we’re also expecting to launch larger tooling soon. We are currently working on documentation and testing for a new batch of end mills that are more specifically designed for the AltMill. This includes larger diameter bits, surfacing tools, and more.
We are quite close to releasing a 2.2KW version of the spindle using ER20 collets, which will also play nicely with the new bits, more details for that to come as well.

New Spindles and VFDs
We have a couple new VFD and spindle kits coming down the pipeline. We’ll have a separate post and pricing for this in the next few weeks, but this includes:
- 220V – 2.2KW ER20 Spindles (AltMill only)
- 110V – 1.5KW ER20 Spindles (AltMill and LongMill)*
*We had initially stated that we didn’t recommend the ER20 spindles for the LongMill. The engineering team has let me know that we want to retract this statement, and also to provide some more context.
The spindle is NOT plug-and-play compatible for machines with the original LongBoard (MK1 and MK2). Support and resources are limited for implementing this set up. Please read this article for more details. Customers who have the LongMill MK2.5 can use the spindle.
These kits are currently only available for customers outside of Canada. Kits certified for Canada are coming soon. More updates to come.
The 1.5KW ER20 spindle kit for the LongMill can be found here.

Close Loop Stepper Motor Kit
As we talked about in the last blog post, we had gotten a lot of feedback for interest in a “close-loop stepper motor kit”. We got nearly 400 respondents with a strong interest in this type of kit. Given the interest, we believe that this would be a viable kit for us to make available.
There are a couple of practical considerations before we move forward with this sort of kit:
- There is a lot of documentation that needs to go into helping users set up their systems
- We need to buy more inventory, which eats into the capital that we are already allocating to our AltMill production currently
- We’re already working on several projects, including the ATC and the AltMill 4×8, which means that we need to consider how thin we’re spreading ourselves with the development
It’s likely that when we get to purchasing Batch 7 in around October, we’ll look again at ordering parts for the kit, or figure out some ways to work on this kit without overburdening our engineering resources in the meantime to get this kit available sooner rather than later.
Automatic Tool Changer
A lot of work continues to go into the ATC project, with a lot of focus in the software and user interface side of things.

We’ve also been ordering some more parts and doing some design work in July as well. We’ve ordered some more parts for this which should arrive in the coming weeks. We’ve now finalized the manifold design and electronics, leaving us with finalizing the design for the toolholder.


gControl Panel Computer
A small piece of exciting news, in July, we shipped our 1000th gControl Panel computer. Which was something that we were expecting to be a minor accessory has been a surprising success in our books. With the popularity, our team is working to offer more resources to help support users. If you haven’t checked out the latest video, here it is:
