I thought I’d document the upgrade process for replacing my hot end/extruder on my mendel90. My printer is definitely showing it’s age as this will be my second replacement hotend. I’ve had it since high school and it’s served me very well. After years of abuse on an e3d v6 hot end that was hackily shoved onto it, it’s finally failed.
The first step is assembling the Titan Aero. This only took about an hour all up. There’s an excellent guide available here and it wasn’t too difficult.
