I was using my XXL this morning, and all was fine, right up until the completion of the job… Once the job finished, I powered-down the spindle, and was releasing the clamps for my piece as the gantry moved to the rear of the machine.
It was then that the issue occurred - for some reason the RHS y motor reached the end of it’s travel, but the LHS motor was still trying to move rearward… the belt sounded like it was grinding, so I immediately powered the entire machine down.
I moved the gantry forward slightly, powered everything back up, and started the homing process through CM… immediately the LHS y axis motor sounded ‘funky’ (as if the belt was trying to skip), and as if the gantry was out of alignment.
I slackened-off the y-axis belts, checked the gantry for square, and all was good… tightened the belts back up, went back through the homing process… same problem.
Any ideas on what might be causing this issue, and/or any possible remedies to the problem?
