How to calibrate the stepper motors for X & Y Axis on RuiDa Controllers using RD Works.
Create a square in RD Works 100x100mm
Cut from a piece of material using the cut settings for that material.
Now measure the X & Y axis.
Follow Directions in Video on how to change the Graph length and the actual measured length to calibrate your stepper motors.
Also shown is how to do this method on a rotary attachment using masking tape to measure each axis.
