Hi All!

I tried to do a PETG print overnight. I woke this morning with a melted blob on the printhead. See picture. How do I get this off, please?

Ugh, just happened to me too, but not quite as bad. Generally, I heat the printhead to the appropriate temp, and then try to pull it off around the nozzle area. when it gets up higher like that, it's harder, and judicious application of a heat gun and tweezers/needle nose pliers to pull it off. Be careful not to melt/deform other plastic parts.

Thanks for your reply Kevin! The fact that its around the wiring is rather concerning.

those braided insulations are for the heat core and are heat resistant. They won't melt like plastic insulation. If you do see plastic insulation though, be careful. Mostly you want to get it soft and pick it to pieces with tweezers.

 You can also use something like flush cutters to cut away some of the plastic, but if you get it warm, it might be easier to just pull it off.

Thanks Kevin! Your comments are very helpful. I'm going to give it a shot this weekend.

if you have a hot knife or soldering iron you can also kindof cut through it. I would try general heat first though.

You can use a hair dryer to start. If you have a soldering hot air, you can direct it pretty specifically, but very high heat can be acheived. if you can get it just hot enough with a hair dryer, you may be able to soften it.
