I have a relatively new Monoprice mini v2. We printed the cat, and I generated some gcode with Cura (3.1.0) which also printed OK. I generated another, and when I print it, the extruder and plate heat up, but just sits at the home location. The progress bar moves along as if it’s doing something, but it never does anything. The temps hit their settings, too.
So I went back and tried the cat again. It printed just fine.
I’ve resorted to copying the header parts of the gcode around from the two working ones, but that makes no difference.
Is there some way to see why it’s stalled, or any known codes that might cause this behavior?
