My X-Carve was working absolutely perfect for 4 years until recently. It would be in the middle of a carve and something would cause it to skip on the Y axis. This would cause the carving to be off. It would only happen on the Y axis so I replaced the stepper motors as suggested by another user. I still have the issue. I checked my V wheels and they are not tight at all. Just for testing purposed I swapped the X and Y axis now the “skipping” occurs on the X axis. Could this be the controller? Could it be a power issue? Any thoughts on this are GREATLY appreciated!
It is time to tram your cnc.
Set the v wheels correctly, one axis at a time.
Set your belt tension, one axis at a time to 3.5 to 5 lbs at a one inch deflection in the center of the belts
Check your Z axis for vertical movement and orientation.
Double check your steps per mm on each axis, one at a time.
Verify your wiring between the controller and each stepper motor with an ohm meter. (unit unplugged, wiring disconnected. should be less than 0.3 ohms on each wire to each axis.)
