I’ve noticed that my Left bushing holder always sits up from the bottom stop and that the right is always flush. With the power off and steppers free to move, I can push down on the left side so that it is flush but after and X-Level its high again. Today I noticed that the cable carrier is binding with the inside front of the frame and seems to be causing the problem.
Maybe remove a segment of cable carrier??
This must be from turning printer upside down and every which way fixing another problem. Fine now.
