At 300IPM I noticed the carriage is getting stuck on the short axis as shown in the video below. I tried to lubricate the lead screw around the position where the motors get stuck but it didn’t help. The stuck issue seems to occur around the same spot.
Also, I noticed that at lower IPM this stuck issue does not show up. Is it possible that this is because lower IPM has higher torque?
Overall I am not sure what this issue is caused by
I believe today one of my cuts got screwed by this issue because the cuts along the short axis got shifted by an inch, as shown below. I suspect this was caused by this motor/axis stuck issue.
