Extruder first run

step

distance

step

• Increase the extruder flow rate to about 30RPM and check it runs without stalling the motor.

• If the motor stalls the most likely cause is the pressure bearings are too tight – undo until

the motor does not stall but the filament is still being extruded.

• If the filament does not flow tighten the bolt slowly until the filament starts to be extruded.
