4.3 Extruder stops in mid-print
This manual will describe step by step what to check and how to solve any issues you encounter if your
filament stops extruding in the middle of your print
Basic checks
To start there are a few basic things to check that can make a big difference:

Laptop screensaver
If you connect your laptop to your printer, it is important to disable your screensaver. If your
screensaver is enabled, the printer stops printing when the screensaver turns on. If you connect
your PC to your printer, it is not necessary to disable your screensaver.

Filament spool
Check if the filament on the spool is entangled. This can make it hard/impossible for the driver
gear to pull through. If this is the case, retract the filament as mentioned before. Make sure the
filament of the spool is free to roll of and reinsert the filament.

Filament
Check if you find scrapings on the filament near the inlet in the electronics cover plate, located
inside your printer. If the inlet is too sharp or the filament is not let in perpendicular, pieces of
the filament can be cut off. Deformation of the filament can result in the driver gear not being
able to get grip on the filament or the hot end not heating the filament properly. Readjust your
filament if necessary.

Extruders
Check if both the extruder fans are working properly. If the fans do not work the extruder will
not be cooled properly causing large fluctuations in the nozzle temperature, which can cause
clogging. If you see that the fans are not spinning, try to give them a push with for example a pen
to get them going. If they still don't start spinning please check if the wiring is connected
properly.
