      Marlin has M425 for backlash compensation. I have not seen anything like in Duet Firmware. Maybe I am missing something?

          Thanks, my printer runs with reciprocating ballscrews and Z being not so heavy I am not happy with.

              shouldnt gravity take care of backlash in Z direction?

                  @PCR unless you are running at 10,000mm/s^2 acceleration in z then I think gravity should still win right? Unless there is an awful lot of 'stiction' in the z bearings.

                  If it is from Z hop, surely you are always approaching the axis from the same direction (downwards), so backlash shouldn't be an issue? Or am I being naive and missing something...?
