I've got a Torchmate 5x10 that until recently was making accurate cuts. We had a situation where the y-axis rail got blocked and caused the table to bind and stop. We've readjusted the table, but now our y-axis cuts are not accurate ( a 96" y-axis cut is cutting at 95-5/8"). We've tried trouble shooting for a couple of days and have literally come up short. Slipping stepper motor? Worn out rack and/or pinion? Thoughts?
