Pulled the sides off and checked the teeth on the belt and on the pulleys, all seem to be good. I also made sure the grub screws were in place and none were missing.
Tightened the Y motor, even though the tension on the belt seemed good. While I had the machine apart, I used your guide to oil the bearings (TY for the guide BTW).
Running another print now to see if it made any difference.
