Great work mate, those hybrid steppers sound pretty nice, was interesting that you clicked on to the noise of "a poor tune" and solved it! I didn't realize that the stm32 have such a low clock rate, I heard you say that you had tried different crystals which I must say Is seriously under the bonnet. From my cheap seat have you looked into ESP32 by Espressif, they have an adjustable clock rate between 80-240Mhz and as you may already know incorporate wireless. I imagine there are other variables which will make for a good or bad motion controller like onboard cache, but that is getting above my pay grade. Respect your work and thanks for the upload
I am gearing up to make a cnc mill using ethercat drivers. Examples I've seen are using velocity command instead of position in LCNC. I guess that way the drives don't accelerate and decelerate to each position but rather small changes in velocity. I don't know much about this stuff just to be sure and I and very impressed by what you've done so far.
Really appreciate your work, for a while I keep thinking on controlling my lathe with ethercat, its just that beckhoff seemed a bit too expensive for experimenting and I was not sure how stable the ethercat master is

very nice , but can we add 4 encoders for the 4 stepgens?
