My Y1 stepper will travel out 700mm and start to skip and not be in sync with the Y2 stepper. Does not do it all the time so is this a speed issue? Also when I auto home x or y all the steppers will skip and move slowly. My CNC is Primo using the Archim 1.0 and its 4’x4’. I did update the firmware so I am assuming the speed is preset? Any help would be appreciated.
