@theo said in Stop stepping motor:

Thanks for your answer A little bit disappointed by your solution. I am sure you feel that is not a clean way to work. Please update me once you have developed a better way to stop a motor . I have used Minitronics for years and stopping a motor is clean. Anyway many thanks for the time spent to study my request

I think it's a pretty good idea. It can all be done in a macro.

Thanks, you're right - it seems OK in Pronterface, so I can use that for hand-tuning the heater. Strange that only M307 seems to be affected, perhaps something to do with Octoprint's temperature polling.
