I came in this morning to find my overnight print (which I have done many times before) stopped working mid print about 4-5 hours into a 10 hour print. Since the printer is in a school that is air conditioned, I do have a heater about 0.5m away from the right side (when looking at the lcd screen) of the printer that has kept the printer warm enough to not have layer delaminations.
When I came in there was a bunch of wigging of the filament near the top layers. The LCD screen was blank/off and unpowered. The D-Pad also was dead and unresponsive. The printer’s white light was on. Nothing was moving and nothing when back to it home position (this is similar to a power loss, but the breaker was good and the power brick still had its blue light on).
My first thought was it was overheaded, but I have done many 8-10 prints overnight with the fan without a problem. So I doubt it was a overheating issue, but I turned off the fan just in case.
Powered Down and UP: Then I turned the printer off, unplugged the power cable, waited a full 60 seconds and then plugged it back in and turned it on. This time the printer light did not come back on and still the LCD display is dead. The D-pad next to it always was dead. There were no startup beeping sounds. I have manually touched the stopper sensors and the small red LEDs do turn on which means there is power coming into the unit.
Possibly Related: Yesterday the Makerbot Print was updated to 2.8 and when we ran print jobs for anything circular, the extruder would shake/vibrate. I have read that there is an acceleration option in the printer’s menu but without a working LCD display, I can’t know for certain.
What could it be? Thoughts? HELP!!! Please
I think that it is either a motherboard replacement or motors have burnt out, but I am just guessing. How could I verify either before buying replacement parts?
