      I've read in a thread that if sensorless homing (CoreXY) makes one axis moving in the other direction it means that the current of the motors is too low, so one motor rotates the other.
      My tests show that M913 behaves the other way around, as follows:

      • setting the current to "70" for both drives triggers the wrong direction movement behavior
      • setting the current to "30" for both drives hits harder than "50". The knock at the end is louder on both axes

      Is M913 reversed? (firmwre 2.0.1)
