Extruder Idler Bar Springs
In order to ensure the extruder maintains good grip on the filament, it’s important to periodically check the springs
that clamp the extruder idler bar in place.
Recommended service interval: once per month or every 40 hours of run time
Use the 2.5mm wrench in your toolkit to tighten the two bolts as far as they will go. They will stop turning when
the tips of the bolts make contact with the extruder motor.

For extruders with the idler bar that shows the idler bearing, reverse the bolts 1-1.5 turns.
For extruders with the larger idler bar, reverse the bolts 2-2.5 turns.
You should be able to slide the springs on and off the idler bar with your fingers with moderate force. If you can’t
disengage the springs by hand, try loosening the bolts an addition half turn.
