Solved - UM2 shuts off during heat up

Recommended Posts

Posted (edited) · Solved - UM2 shuts off during heat up

Okay weird problem here,

I removed my olsson heater tip and when I turned my UM2 on to heat it and put the tip back in the lights start flickering and the machine suddenly shuts off then restarts and sits at the home screen. If I try to heat up the nozzle at all it flickers and dies. I can heat up the buildplate no problem but if I set the nozzle even one degree up it flickers and dies. So is the problem most likely a short in the heater element or thermistor?

If anyone encounter this problem I found that the heater element wire was touching the back of the metal shroud for the fans. It burnt through the nylon wrapping and was shorting on the shroud. If you are luck not much damage will come to your wires and they will still be insulated. I bent the shroud back so it wasn't touching and now it works fine again. I guess next thing to look at it how to keep the shroud from getting hot/ touching the nozzle.

If your cables are damages, maybe you could use some silicone as insulator? Normally, silicone is heat resistant up to 220°C ... 250°C; but there may also be high-temp versions. Or use shrink wrapping for cables (not sure if that is the correct English term): the sort of black tubing that you put around cables and then shrink with heat from a heat gun or soldering iron.
