I’ve been printing happily for many months, but today my printer was maybe 5% through a 1 1/2 hr print, and has just stopped. No obvious reason. I clicked Abort print.
Computer is still connected, fan whirrs, but can’t move print head - Home Z, Home All do nothing.
I have checked that computer didn’t power down, and have unplugged and replugged the USB cable at each end.
Switched off printer and did something else for a while, thinking the printer had had a near-total hardware failure.
Went back, switched everything back on. Restarted Cura. Reconnected printer, and to see if ANYTHING was working, clicked on Preheat nozzle. The temperature started rising, so the computer was seeing the printer.
Everything suddenly sprang back to life.The printer homed to its Home All position. After cleaning some stuck ABS from the nozzle, I restarted the interrupted print, and it seems to be starting fine.
Should I put this down to a one-off glitch, or is it a sign of hardware problems that maybe I should try to diagnose further?
