X/Y Axis Vibration

Post by CaldwellAZ » Wed Jun 16, 2021 2:35 pm

Hi, We have an 80w Red & Black Chinese laser. We've had a lot of alignment issues and now I've noticed it is vibrating quite a bit when moving. We've added a beam combiner to get a better alignment, but if you look at the video: https://youtu.be/wlypiBAaZ3g, you can see the beam jumps all over the place when moving (especially along the Y axis). This is resulting in weak and dashed cut lines.
I've checked the belt tensions - no change between tighter or looser. It does the same thing. Tracks and bearings seem OK.
Has anyone seen this before or have any idea what to check?
Thanks in advance!
Scott & Mary
