X y and z were all working fine… did some practice, simple carves and with different bits… but now the x-axis will not jog to the left… It’s jogs a few times, then suddenly stops and will “click” if I try to jog it one more time. No issues with it going to the right, up, down or forward/backward?
After jogging it to the right a few times, I can jog it back to the left the same, few times, and then it clicks and won’t move. The stepper turns as though there’s nothing wrong, but the belt teeth doesn’t appear to be gripping the stepper teeth, and just spins underneath. Not sure how much more the belt can be tightened?
1000m…in my efforts to figure this out, I completely loosened the belt, and turned off the machine, so I can manually slide the x-axis housing by hand (and no strain on the stepper motor). I again, can roll the housing to the right, but as I roll it back to the left, it acts like a car bumping up to a shopping center concrete parking stop barrier? I cannot find anything in the way on the tracks. The wheels spin smoothly…?
I heard a vibe they other night, and couldn’t find where it was coming from. Fast-forward, while inspecting the top z-stepper & belt, I found the problem…
One of the z-stepper mounts/screws came lose/apart and dropped inside of the gantry track, where I couldn’t see. Found the bolt and flat washer inside my vacuum cannister. Had to remove bottom track wheels of the gantry to be able to get to the lost screw. Then put everything back together. My Lord what a lesson.
