I can’t seem to get the correct Rotational Distance values for X,Y,Z. The original Modix config lists the Step_per_MM as X100 Y100 Z2000 and below is the hardware config.
1.8 degree Stepper motors on all
Microsteps = 16
Single Y Axis motor with a 16 Tooth pulley and GT2 (2mm Pitch) belt.
Dual X Axis motors with 16 Tooth pulleys and GT2 (2mm Pitch) belts.
Quad Z Axis motors with 16 to 40 Tooth pulleys (16 on stepper, 40 on ball screw)
Going on the formulas in the Klipper documentation I’ve calculated the values should be X=32, Y=32, Z=1.6. When I ask the printer to move say 100mm it only moves around half of that.
Out of curiosity (I know Klipper recommends against it) I did the measure and trim method the value that move the correct distance (accuracy aside) are X64, Y64, Z3.2
