Overview

How it was Done

Well this took a lot longer to fix than I was hoping for. In this video I attempt to repair the annoying overly gunked up hotend.

If your gunked up hotend is not as bad as mine, you may just be able to heat it up to extrusion temperatures and carefully remove and clean everything. Unfortunately, that was not the case for me.

I ended up having to replace more parts than I was hoping near the beginning of the video. Below are the parts I used (affiliate links – no extra charge to you)
