All of a sudden my x drive goes into violent oscillations when printing. It starts printing OK but then starts oscillating sometimes intermittent sometimes non stop. It seems to start oscillating in the same areas. Cant find any interference's. It also continues to print but model shifts.

It dosent buzz when I try homing or jogging. Sometimes my display goes whacko at the same time. If I pause and then unpause it starts buzzing again. Any ideas?

I tried to tighten the x belt but I can't figure out how to release the clamp.

All ideas welcome
