ER11 - Hopper nearly empty

To prevent system damage, insert new material into the hopper or stop the extrusion experiment.

This warning is displayed when the hopper input sensor could not detect input material at the hopper entry. The warning is displayed to prevent the extrusion system from running empty, which could potentially damage the machine.

Steps to resolve

Feed new material into the hopper of the Filament maker TWO within 5 minutes, or stop the extrusion experiment. This prevents the hopper from running empty completely.

The warning automatically disappears when new material is detected by the hopper input sensor.
