Hi all ,

im new to the world of homebuild CNC , i purchased a cnc router a few years ago and all has been running fine until recently when i moved the machine. The z axis stepper motor seems to stop working at random intervals , ive attached a small clip of the issue as difficult to describe. ( wont let me upload )

The spindle attempts to turn however seems to jam up. It then almost jerks in random motions whilst making a whirring sounds.

Any ideas or help would be really appreciated

Thanks in advance
Adam
