Extruder Heats Immediately when Turning on the Printer Until I get a Max Temp Error

Posted (edited) · Extruder Heats Immediately when Turning on the Printer Until I get a Max Temp Error

I have Ultimaker 2 Extended and It was working perfectly, until the filament broke while printing. I aborted the print and went to change the filament. I removed the Bowden tube and the printer turned off then on again (Electric Short). Now every time I turn on the printer the extruder heats immediately very fast until I get a max temp error.

I checked the thermocouple and the heater wires everything is connected from both ends. I tried the factory reset and noting happened, now I can't check anything or use the LCD screen because I need to do the initial setup but I can't because the heating is faster than the setup steps :)

    I removed the heat cartridge from the head and turned the printer on and it start heating up.

    Is it a firmware issue where there is a command letting the heat cartridge heats immediately?

    No. Test one more thing though... the reported temperature - click on MAINTENANCE ADVANCED then go to nozzle temperature and check what the reported temperature is. It should start off around 20C and quickly go up as the nozzle heats up. Do this with the heater inserted as you can destroy the heater within about 10 seconds but inside the aluminum block you have much more time - at least 30 seconds.

    If the temperature is negative then this *might* explain your problem but I doubt it will be negative. If the temperature looks correct (between 20C and 300c) then...

    Your circuit board is probably defective. The circuit board uses a part called a FET, specifically I think a MOSFET. That part commonly fails in two possible ways: always on, always off. Yours seems to have failed in the always on mode. This failure is unusual but can happen if you short out the heater briefly - then you have hundreds of watts going through a tiny part and it melts.

    Contact support.ultimaker.com and explain this and ask for a new PCB. They will most likely send you a new one for free. Alternatively if you have very good soldering skills (with surface mount parts - very tricky!) you could replace the part yourself - the schematics are all available.
