⬢Release both M3 screws and remove the Extruder-cover so you can reach the hotend.
WARNING: Removing hotend from the extruder requires "special" technique, then the hotend slides out quite easily. Don't use excessive force, or you will damage some parts irreversibly!!!
⬢The hotend is removed by inclining and pulling at the same time. See the picture showing the WRONG inclination. This hotend is inclined too much to the front and there is no gap between the hotend and the extruder body. Hotend is partly inside and you won't be able to remove it.
⬢The second picture is showing the CORRECT inclination. The hotend is tilted, but there is a gap between the hotend and the extruder body. You will be able to remove it.
⬢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.
