Hi!
Today was running program and everything worked like always.
Suddenly the z axis did strange noise and whole machine vibrated when z axis did rapid motion.
With feed it also moves jerky and when rapids engage... Crazy vibration.
Belt seemed to run fine and servo motor did not hear / feel unusual. I was working alone and i need somebody to push rapid button to hear/feel the z axis motor.
A bearing failure?
How big job it is to remove the z axis ballscrew/thrust bearings?
How to approach the disassembly?
Belt is tightened and fixed in place with motor mounting bolts?
A short clip of the vibration:
