6. Calibrate the Z axis (Fig. 6): bring the build surface to the
nozzle and save as zero height the position where the tape just
starts to pinch.
7. Insert the filament in the blue hose (Fig. 5f) and align it with
the motor’s teeth (Fig. 5g).
8. Activate the rocker switch to load the filament (Fig. 5h) and
lock the filament guide tube.
Generate the G-code for the AM system from the previously
created .STL file via the same controlling software:
1. Import the STL file of the part to be printed.
2. Run the slicing software and set the following parameters:
