TAZ3, Budaschnozzle 2.0c with 0.35mm nozzle.
So I noticed that the coating on the stock power resistor has / has started to melt off under normal use.
Is this cause for concern? Or is this totally normal and nothing to worry about?
It’s certainly not normal for that to be occurring. Have you applied the TAZ3 24v Marlin update with adjusted power settings for the hot end? More information can be found here: https://www.lulzbot.com/marlin-24v-heater-resistor-update. If this heater resistor needs to be replaced we can send a replacement (looks like it does), please send in the following information:
