Mistakes on the mill…

While waiting patiently for the mill to finish running a PCB isolation route job I stepped away for a few seconds to skip a song on my music playlist. As I was fiddling with the music I heard the spindle motor starting to bog down and turned around to see that the cutting tool had started cutting deeper and deeper into the PCB material, the MDF board it was resting on and the PVC mill table…

I quickly hit the emergency stop button, killed power to the spindle motor and raised the Z-axis. At first I thought that the program had decided to plunge into the table but it quickly became apparent that was not the case. The heat of the spindle motor had made it slip down in the motor mount, the Z axis stepper had stayed perfectly still the whole time. I tightened the screws that clamp down on the motor and all seems fine now.

No real damage done to the mill, it’s just a little bit annoying… Ahh well!!
