I just received my Mini from Amazon on Thursday, and finally opened the box today. My rocktopus printed perfectly. A few hours later, I decided to print a Marvin. Unfortunately, the y-axis never moved, and the extruder tried to clean itself in mid-air. The print head ended up diving into the bed and leaving the mark seen in the attached photo - I’m assuming that’s bad. I’m not sure if that means I need a new PEI sheet or not.
I planned on installing a dampener once I was comfortable that the printer was working, so I figured it was a good excuse to check the motor itself. It turns out that one of the 4 pins in the motor power connector has fallen off and has now disappeared into the black hole that is my work area. Can anyone recommend a replacement for that plastic connector? I didn’t see anything on the parts list in the lulzbot store that looked remotely appropriate.
Also, what’s the right way to stop an obviously bad print from continuing? I hit cancel in Cura, but that didn’t seem to do what I expected.
