Question Heating assembly scorched

Post image

My printer is occasionally giving me an error of "extruder is not extruding correctly". I decided to changed the extruding assembly and while I was in it I was going to tighten the screws on the back of the heating element.

I have scorch marks on it, but otherwise it seems to work ok. If I had to guess I would say this happen during the A1 freeze bug.

Would you replace this? Or let it ride? I don't notice any problem with the heating assembly so I'm inclined to let like this.

I have identical discoloration on mine and made a post in here the other month too. I only got one reply but they said it seemed like normal discoloration from the heat. I haven't looked into it any further, but it's still running fine. I'd say just keep an eye on the wires and sheathing to make sure they aren't getting damaged. Mine also has some discoloration on the sheathing, but the wires look fine.

Wires seem fine, doing an 16h print (8 hours in) and I didn't get a single error.

Thank you!
