Open-source industrial servo motor

I recently discovered this kickstarter (no affiliation) for a closed-loop stepper retrofit controller. This is very interesting. Check it out!

Cute!

Shame they've capped it at 24V though, means it's kinda limited to the same gear that can be driven directly from a controller board with baby drivers on it.

If they'd gone for 48 or 70V support it would have been extremely cool for the CNC router crew.

yeah thats true, but could still be good for a 3d printer, should eliminate any z layer shifts due to plastic catching on the nozzle from time to time.

It will help fix prints, but with no way for it to keep the rest of it in the loop, then we could easily see it drawing a large section of a layer as garbage, and causing more issues as the print continues, so while it will eliminate large shifts, realistically the parts will still be flawed, although less obviously.

Well, if you look at the current smoothieboard and even the duet wifi coming out, there are plenty of digital I/O that can be used as a feedback. I feel like a little modification to the current firmware will address that issue.

If I am reading it write you can get torque feedback. That could be a simple way to find Z zero by just tapping the nozzle on the bed.
Or getting some feedback from the extruder about just how hard it is pushing.

Not torque so much as you can tell when it failed to move for whatever reason. Not quite the same thing.

exactly what I was thinking too, I will definitely be exploring the possibly of using these as a zprobe (I backed them). If they work, it would be quite accurate.
