I installed new upgraded stepper motors and belts. The install is complete. The machine worked as it should before the upgrade. I ran a square (cut at .1 deep) in the waste board to confirm that the assembly was square. I made this square 17”x17”. I cut the outline of the square from center. The machine did as I asked, but cut the square 21”x21”. I did this again for 12”x12” and it once again cut very evenly and straight, but larger than designed.
I have absolutely no idea why this is happening. HELP!!!
