Please can anyone give me hint what´s wrong
After half cutting the project
The z axis is going sporadically up and down in small steps
without going down and cutting
This happen suddenly.today
Hasn’t happened before
Check over your z axis wiring connections.
Also consider a wire may be broken internally without breaking the insulation.
Can you jog the z manually without issue?
