OctoPrint error and print stops?
Posted: Mon Jan 12, 2015 3:59 pm
I have a puzzling problem with my OctoPi setup. I've got a Rostock MAX v2 and I've been printing from MatterControl on my PC just fine for weeks.
I'm finally able to begin a print from my Pi, but it stops suddenly mid-print. I get errors that timeouts and "expected line X" (sorry, I'll get specifics when I can). I've only tried one print so far (as in, one GCODE file), but I've tried it several times. The print freezes reliably at the exact same place in the print I've been attempting, which struck me as odd. I changed the bitrate to 57600, but this did not help. Additionally, the GCODE was created from KISSlicer, which I haven't used before. I also increased some of the timeout configuration settings in OctoPi, but that had no effect.
My most pressing need is some advice regarding how it fails. When it fails, the hot end is immobilized, and target temperatures are not changed, so the hot end starts melting the existing print and my build plate! I'm printing on BuildTak on top of glass. I don't have failures like this often (freezes), and I don't recall if I've had a failure that kept the hot end on like this. It has me very worried about creating a fire hazard. If this could be solved with better error-handling in OctoPrint, I'd definitely want to look into alternatives. Are failures of this nature typical? Should I even be worried about failures like this?
