Desmontaje del ventilador del hotend y FS-cover
Release and remove the M3x10 screw on top.
Remove the FS-cover. It will be replaced with a new one.
Release the M3x40 Idler tension screw with the spring on the side. You can leave it
in place.
Release the M2x8 screw, unplug and remove the IR filament sensor.
Be careful with the IR filament sensor, hold it by its sides. Try not touching the
components on the PCB. Keep it in an ESD-safe place.
Release both M3x40 screws on the front, just few turns to create about 0.5cm
(0.2inch) gap in the extruder body.
Release and remove all screws holding the Hotend fan on the side. Remove the fan.
We need to reach a screw behind the fan.

Release and remove the M3x40 screw on the back holding the Extruder-idler on the
side.
Retira el Extrusor-tensor de la impresora.
Remove the other M3x40 screw on the back.
From now on, try keeping the extruder parts together as it can easily fall apart while
it's not being held together by the screws!
Using an Allen key, push the black Adapter-printer part up. Keep in mind there is a
steel ball inside, which usually falls out. Remove the part entirely.
We will replace Adapter-printer part with a new part.
