I’m seeing a weird issue which maybe points to a faulty XY motor:
- I did a pencil test for line straightness and 90 degree corners.
- In the top central area, the sled jumps up producing visible notches. This happens only in the top middle of the work area, other places are OK.
- The jumps happen only when sled is moving left to right. When it is moving right to left the line is perfectly straight.
From my initial research, it could have been a chain skip, sled being too heavy, or issues with motor controller. I’ve checked for it and chain is definitely not skipping. The issue also happens without bricks on the sled so weight doesn’t seem to be a problem. Guess it’s the motor?
I’m attaching a few photos. Have anyone seen anything like that before? Any recommendations?
