Initializing problems

In the middle of a job, the bit started to plunge deep, so I stopped the program. When I tried to initialize the machine, it started bouncing up and down and then Carbide Motion turned itself off. What could be wrong? I think you can see a video of it here: This is what happens when I try to initialize the machine | By Glen | Facebook

Hi @GlenSpicer,

From the video it looks like it could the pulley slipping on the Z motor shaft (maybe it got loose after the plunge incident?). Can you try and look if you see the pulley turning normally while the Z axis itself dances up and down as it does in the video ? or does the pulley rattle back and forth too ? (which would rather indicate an electrical issue)

Either way you can also contact to troubleshoot the problem.

There is no slack at mall in the pulley nthat bI can see.

Allright, another possible culprit is a loose Z belt, which would then slip on the pulley. On a belt-driven Z axis that is a common thing to happen. The crash you had may have knocked off position the belt tensioning screw.
Check that? The belt should be tight.
