XYZ carve - X axis compressed movement


Hi Ben and cnc folk,

Mid job the machine froze. Now when I try and cut a lob the X is not right. Its only moving a fraction compared to the y axis. In other words if I try to cut a circle I end up with very compressed ellipse?

Any thoughts where I should turn my attention to resolve this problem?



To answer my own question… I replaced the x axis 4 stepper driver on the CNC shield with a spare and that fixed it. I did notice they are running quite hot. Is this normal?
