Z-Axis stopped responding

Post by ZachKaplan » Sat Apr 19, 2014 5:59 pm

I was running a job and the Z-Axis stopped responding. I am not able to drive in with Gcode Sender either. I did some inspection and one of the wires on the Z was loose. I got a screw driver and tightened it but still nothing.

Does this mean I shorted the Z-axis stepper and I need a new G-shield?

Sounds likely. You could try swapping the wires to another motor and make sure it's not the stepper motor itself.

Good call. Looks like the stepper is fine and I broke the driver. I replaced the g-shield and I'm back up and running but when it steps down I get a weird knocking sound. When it steps up it sounds smooth. While doing an air job...

When it goes up it's got that nice smooth zing zing zing zing

When it steps down it goes thud thud thud thud
