Is there no alarm when the gcode XYZ values are outside the machines travel? I just had about 7-8 mm of the model clipped off on the back side. The Printer posted no error message or alarm. Octopi posted no errors or alarms. I didn't notice it because the section was printed while I was not baby sitting it. Once it was past it, it wasn't noticeable until removed from the bed.
