I built a CNC Laser cutter a few years ago, it has been running fine until a few days ago.
First the X Axis failed and when I tried to cut something it just draw a line parallel to the Y Axis.
I replaced the motor controller and it worked just fine. A few days passed and it started to have some issues in the X Axis, this time there is some misalignment in complex cuts, I run some tests and the problem amplifies the more the axes are moved. I've tried every idea I had for the last week or so, like verifying every connection, replacing the motor, replacing the mach3 controller, I even reconstructed the axis in hope it was some mechanical issue and now it happens in both axes. I've run out of ideas.
Attached is a photo of the problem, I cut the rectangle then move both axis and rerun the gcode, but the cut is misaligned from the original.
If any of you guys have had the same issue or have some idea of what might be causing the problem, I would be extremely grateful if you share it with me.
