⇒ Wait until the extruder has reached the required temperature. The current tem-
perature and the required temperature are shown at the top of the display�

⇒ The filament can be extruded using the "EXTRUDE"
will only turn for as long as you press the button�
Alternatively:
⇒ Press the load filament
This can be canceled by pressing the lower left arrow
⇒ Now insert the end of the filament guiding tube into the upper opening of the
extruder again.
⇒ Place the cover on the printer� Pay attention to the cable of the fan�
If the fan cable has come loose, first switch off the printer before you insert
the connector into the unit again.

FMS system
The filament sensor (FMS) controls the filament flow during printing.
If a jam is detected during printing, the printer attempts to fix this itself as part of an automatic fault correc-
tion process�
You must ensure that the FMS system is always calibrated with the currently loaded filament and
the corresponding temperature. If this is not the case, the filament flow cannot be properly moni-
tored during printing.
The FMS system is negatively impacted, and printing is not correctly monitored.

Calibrating the FMS system
A video on this topic is provided under the following link

The FMS system must be calibrated in order for it to operate correctly.
As a result of the previous steps, the extruder is already heated up and the
filament is loaded.
⇒ Select calibration with the
The FMS system must be calibrated with the filament used correctly
selected.
If you replace the filament, i.e., use a different type, the FMS system
must be recalibrated.
⇒ If necessary, change the selected filament with the
⇒ Start the calibration using the start icon
♦ The print head and print bed are moved to the home position�
♦ The print head is moved to a position beside the print bed�
♦ A preset quantity of material is extruded.
After successful calibration, this is shown on the display�
If calibration is not successful, an error message is shown�
⇒ In this case, repeat calibration�
After calibration has been completed, the FMS system is adapted to the filament used and can
detect and display errors in the filament flow.
⇒ Press the lower left arrow
button. This automatically extrudes 15 cm of filament.
