⬢Release both M3 screws and remove the Extruder-cover so you can reach the hotend.
WARNING: Removing hotend from the extruder needs a "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.
EXTRA WARNING!!! Be extremely cautious during this step!!! You can easily strip the lock screw and irreversibly damage it.
⬢First, make sure the Bondtech isn't glued to the shaft. This is valid in case of the pre-assembled printer. If there is a glue, heat the shaft first (heatgun, lighter). Be careful, you can burn yourself.
⬢Second, carefully release the lock screw. If the resistance is too high, use a grease (e.g. WD-40) and wait for a while.
⬢Remove the Bondtech gear from the shaft and keep it for later.
