7.4. Replacing the fan set 
If you have encounter problems because the BL touches 
intermiently or is not working at all or the fans are not 
working, then follow the process below to investigate. 
This could be due to pins breaking or being misaligned 
due to twisting of the Fan casing.
•  Remove the screws on the le and right side with the 
2 mm Allen key.
•  With one hand, hold the fan assembly steady as you 
remove the last of the bolts. 
•  Lower the fan set about one centimeter and then 
move it forward and away from the Extruder.
7.5. Relocating the fan assembly to 
the extruder assembly
•  Move the fan Assembly over the extruder first about 
1 centimeter below the required height. Gently li 
the fan assembly to connect to the 2 boards together 
but first insert the central pin from the Extender 
board into the hole of the Fan extender board below 
it.
•  When you have inserted the pin into 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 inserting 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 le bolt hole 
to hold the fan assembly more level and upright on 
the extruder Assembly. Now use the Allen key to 
secure all 4 of the bolts that aach the fan set to the 
extruder assembly.
•  Now you have finished disassembling and 
reassembling the extruder fan set from the extruder 
assembly.
