The fan for my right extruder (CTC Bizer Dual) had started to run a little slowly so I replaced it. Did all the checks that I had rewired a new one (12V/40mm) properly. It ran ok during preheat and kicked in at 50’c like normal. Changed it to feed in the filament and the fan stopped even when it was over 150’c. Left it to cool down as I didn’t want any damage to the stepper motor etc. Tried again all seemed to be working, kicked in at 50’c even on filament feed but half way through feeding in filament it set itself on fire!!! I unfortunately have no more spare fans so can’t retry just yet. Could this just have been a faulty fan or a bigger issue??
