  Thanks for your suggestions! I will try to remove the wago connectors and solder the cables instead. (The wago connectors were only 6 month old.) I will replace the cable between the powersupply and the Duet and the Duex5. So I can exclude a cable break. The screws were very tight. This could not be the problem. Thanks to deckingman and Mr. Crocker.

  I don't know why it only occurs on a layer change. The DRV8825 datasheet says it requires 1.9us step pulse with, 1.9us setup pulse interval, and setup and hold times both 650ns. So you should use at least T1.9:1.9:0.65:0.65 in the M569 command. What's surprising is that it works at all if you don't extend the step pulse width. In practice, the values you specify in the T parameter get rounded up to the nearest multiple of the step pulse clock interval, which on the Arduino/RADDS is 1.52us.

  @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.
