Right now, I'm trying to decide if I want to make the boards available as a product or not. There is also the possibility of just selling the pre-programmed PIC-SERVO S3 controller chip. (Unfortunately, I can't open-source the controller chip firmware because it is based on proprietary code not owned by me.) Hopefully, I'll have my plans sorted out early next year and will make an announcement if the board or controller chip become available.

Well its an open source community. The stuff that is closed is then probably dead in the water, at least for me.

I'm definitely interested in testing your solution out. Does this cut down on resonance quite a bit?

As a potential bonus, it would be really nice to monitor the servo error of a closed-loop controlled stepper - you could detect stalling (very large error), stripped filament (very small error) and also loss of filament altogether (zero error).

Did this ever became a reality?
If so - where can i get some?
Can it be used with any stepper driver?
I'm building a fairly larger printer, and this would be nice for a week long print

PIC-SERVO S3 Firmware: You could release just the modification bits source code, and everyone could modify their firmware themselves?
I'm not sure how it works, but assuming since you have modified it, the source code can be acquired and hence modified by any interested party perhaps?
If not then this is a dead end
