8.5. Replace the Fan set

If you have any problems from the BL touch intermittently
or not working altogether or the fans not working, then
Please follow the process below to investigate. This could
be due to pins breaking or being miss aligned due to
twisting of the Fan casing.
• On the left and the right side remove the screws with
the 2 mm Allen key.

remove the last of the bolts.

move it forward away from the Extruder.

below the required height around about 1 centimeter.
Gently lift the fan assembly to connect to the 2
boards together but first locate the central pin from
the Extender board into the hole of the Fan extender
board below it.
• When you have located the central hole align the side
bolt holes of the Extruder with the fan casing holes
and place an Allen key into the front bolt hole on the
right side again to keep it steady.
• Start to place the first bolt into the rear hole on the
right side. To hold the correct position taking some of
the stress off the pins.
• Place the second bolt into the front left bolt hole to
hold the fan assembly more level and upright onto
the extruder Assembly. Now Remove the Allen key, to
secure all 4 of the bolts to hold the fan set onto the
extruder assembly.
