⬢We are done here!
Before you move on, let's recap:
⬢Store or throw away all the old plastic parts, you won't need them.
⬢Keep both fans, hotend (with replaced PTFE), Nylon filament and the X-axis belt.
⬢Keep the motor and both Bondtech gears including bearings and the shaft.
⬢The disassembled filament sensor with the cable will be replaced with a new one. You can keep this one for your future projects ;)
⬢Fasteners are included in the upgrade kit. However, keep the ones from the extruder as a spare.
⬢Ready? It's time for: 3A. MK3 Extruder upgrade.
