So... Everything was working fine for about a week, I got my final tool up and running, and set my pre, and post parameters for pickup location in the config for this tool. Next time I hit home all, my coupler stepper rotates to home, and continues attempting to rotate, making a continuous popping sound. My guess, after adjusting all the stall limit settings to a much higher sensitivity, is that with the default value of 5, that my stepper stripped itself? I just ordered 2 more Coupler stepper motors, with the sound coming from the motor clicking, I don't think that's a stall, has anyone else had issues with their couplers?

i cant seem to get the stall to work on the coupler motor at all and now its stripped and doesnt move anymore, it was also getting really hot ant its set to 400ma in the config, been using duet boards on 4 machines for a few years now but having issues with this setup
have you figured out a solution yet? my new coupler motor is going to be here today and not trying to fuck this one up right away
I gave up trying to get stall detection working on the coupler motor. You can tune it to work when the motor is cold, but then it reports a stall immediately when the motor is hot. Or, if you increase the M915 S parameter so that it works when the motor is hot, it doesn't register a stall when the motor is cold. I reverted to Greg's C axis settings, or something like them. The motor does get hot if you run it continuously at 400mA; however Greg's settings keep the motor at lower current most of the time, and only increase it to 400mA when turning the motor. You can find my settings at https://github.com/Duet3D/RRF-machine-config-files/tree/master/E3D_Tool_Changer.
