Duet 3 RRF 3 Stepper motors pausing
-
This has been on ongoing issue. I will home the printer and during homing the motors will pause. Come to a full stop then continue on. I haven't seen anything that indicates what could be causing this.
-
Please post your config.g. XY stuttering can be caused by using mesh compensation and having a too low Z jerk value which causes the XY to pause to allow time for the Z axis to change height since it's a coordinated move. Increasing the Z axis jerk to at least 60mm/min is usually enough to solve it.
If that's not the case, please provide more details.

@Phaedrux I will check that when I get home from work and respond. Thank you.

@mrenz999 said in Duet 3 RRF 3 Stepper motors pausing:
M566 X900.00 Y900.00 Z12.00 E120.00 ; set maximum instantaneous speed changes (mm/min)
As I suspected.
-
@Phaedrux What should it be for the z ?
-
@mrenz999 a good place to start is doubling it. Then double again. Once it works you are good. Or try 60 as was suggested before.
