Hello guys,
I had a blob during a print of PETG.
During the cleanup I broke the thermistor cable at the nozzle side and display of temperature gone to 0 - which is expected.
Removed the nozzle, removed the shroud and fan.
Removed the extruder motor assembly, then removed the heat assembly.
Replaced with new heating assembly being extra careful not to bend the cables unnecessarily.
Assembled back carefully, turned on the printer, but still no 0 at the temperature and the nozzle fan goes to full speed few seconds after the start of the printer once again.
The guide on the error says to swap a new heating assembly, but that I already did.
Topics say that there could be no communication problem to the TC board if temp is shown as 0, but that makes no logic as the problem occurred when the nozzle cable broke and it was fine before that.
Error on display is: HMS_0300-0200-0001-0002
