Adjusting the spring tension
The spring tension of the extruder must be adjusted. To adjust the spring tension, turn the thumb
screw on the top of the extruder. Turning it clockwise increases the spring tension and thus exerts
more pressure on the filament.
Recommended spring tension
The spring block should be aligned with the face of the tension lever. Depending on the material
used, further adjustments may be necessary, e.g. additional tension for flexible filaments. The teeth
of the gear should be fully visible in the filament, but should not leave deep notches.
Make sure the temperature of the Nozzle is below 50°C every time you turn off the machine to
prevent clogging or damage to the hotend.
