February 2024 Production Updates

Hey everyone, welcome to our February 2024 Production Updates.

Media Room and Workshops

Since we’ve moved into our new space, we’ve dedicated an area as a “media room”. The idea is to build a space that allows us to make content more quickly with dedicated space, lights, and machines for filming and education. Additionally, we’ve gotten a lot of interest in doing workshops, and so we’re now looking into planning workshops in the space as well.

If you’d like to provide some feedback and let us know what sort of workshops and content you’d like to see, please check out https://sienci.com/2024/01/10/fill-out-our-cnc-workshop-survey/

LongMill MK2s

Production for the LongMill continues to move smoothly. Orders are shipping out within one week, however we are running low on controller boards. Lead times may get longer this month.

Injection-molded middle feet that are used for supporting the rails have finally completed production and are on the way to us. We expect these feet to arrive in early Feburary. For those who haven’t been following along on this change, we decided to start injection molding these parts since we make a lot of them using the print farm and we crossed the point where it would be faster and more economical to injection mold them. It should be noted that this change is to improve production efficiency and reduce costs, but won’t make a difference to the LongMill’s performance.

The bristles that we use for the LongMill dust shoes have come in earlier this year but we have been dealing with quality issues. We have been able to use some of the good bristles, but we’re also working on sourcing a new manufacturer to improve the quality.

We are now starting production on Batch 9 LongMill MK2s. We currently have around around 750 LongMills in stock, and expect to start shipping Batch 9 machines in the spring of 2024.

Spring Loaded Anti-Backlash Nut

Second batch of prototypes

I know a lot of people have been anxiously waiting for the spring-loaded anti-backlash nuts. While they seem simple, these have been a really fascinating but challenging project as we needed to make changes and considerations to the design and manufacturing process of the nut.

For more details about the process of design and making the nuts, I wrote another blog article. The first 200 sets of T12 and T8 nuts are expected to arrive in the first week of February. Please note that the blog article will include more updates once the first batch of prototype nuts arrives.

Vortex Rotary Axis and LaserBeam

Parts for the Rotary Axis have arrived and are being packed and assembled. We have another 300 units in stock now.

Ikenna and Abeiku are also working on a new magnetic mount design and also a riser mount to be used with the Vortex to allow for easier laser engraving on round objects soon, so make sure to keep an eye peeled for that.

AltMill

We have our major components arrived here and are working on putting together and testing the first prototype. Based on looking at the linear motion and extrusions, everything looks great and we’re excited to get everything in to start building the first batch.

Here are some other updates:

  • While we have received one set of extrusions, the full batch of 50 sets have had some QC issues and are being worked on now. We expect them to be finished in the next 2 weeks and get prepped for shipping
  • We have received a few additional closed-loop stepper motors for testing and will be working on having them set up for testing
  • We are working with Andrew at Expatria to figure out what modifications we need to make for the SLB to allow for use with AltMill.

Also, check out this new logo that Leandro made for the AltMill.

We are tentatively looking at a launch date for the end of March. We’ll keep people updates so make sure to follow along on the development through the blog and such.

CO2 Laser

Ikenna and his team have been continuing to work on the CO2 Laser. Here’s a photo of the mockup in progress.

I probably won’t be continuing to put updates for this project on the production updates here because Ikenna will make a separate post as updates come. Make sure to sign up for the CO2 mailing list for all updates as they come.

Sienci Router

Testing with the 400 watt motor looks to show that using BLDC is a promising technology and shows that power output even at 400 watts is comparible to the Makita router. However, we feel that to bring the most value to users, having a bit more power will be beneficial since:

  • Cutting using larger bits, such as the surfacing bit causes the Makita router to bog down
  • Additional headroom allows us to run the LongMill faster alongside other future improvements to speed and rigidity
  • Potential to be a viable option for higher-end machines and the AltMill.
  • Creates a differentiation between our router and the Makita router

Having a larger motor is more expensive, but still within our budget. Pricing is still yet to be determined, but we believe that if we have an option around the $250 mark will allow us to provide a tool that sits somewhere between a traditional router like the Makita RT0701 and a 3 phase spindle.

A second batch of motor samples are expected to ship in the first week of Feburary. We are also in the design and sourcing stage for the motor body and bearings.

SuperLongBoard

Development continues for the SLB and third version prototype is currently in testing. Here’s some news:

  • SLB resources continue to be developed ahead of shipping
  • E-stop injection molded case, buttons, and circuitry have arrived for testing, and have started on full scale production
  • Enclosure parts are getting prepared for shipping

Otherwise we are just working through general bug fixes and testing as usual.

Demand for the SLB has been strong, and we are expecting to sell out of the first batch before we start shipping, so we are working on
