Hello, as seen/heard in the linked video two times. The extruder on my Zortrax M200 v4 has a thumping noise when in operation. I upgraded the hotend to all metal Micro Swiss upgrade and I’m having print quality troubles as well as clear stringy unmelted filament when removing material. Need help, this printer was great until this upgrade!
