o Step 4: Determine the proper distance of the bearing
Grab a drill with a diameter of 1.5mm (or anything else with this diameter) and stick it on
the hole of the hot end tube. It should also be positioned against the groove of the driver
gear. Next, place the bearing plate in such a way that the bearing is tight against the drill
bit. Then tighten the two bolts holding the bearing plate in order to fixate the bearing.
o Step 5: Testing
Now that you have adjusted the distance, rebuild the extruder carriage as it was and try
to extrude 10 mm of filament and afterwards retract your filament again to check if the
filament is severely deformed or has no marks at all. If it does not display any marks,
insert the filament again and try to extrude a couple of centimetres to make sure the
extruder is working properly
Figure: Sketch of the filament for three types of distances between the driver gear and the bearing. Left shows when they are too far apart. The
middle shows the correct distance and the right sketch displays the filament when the distance is too small.
