5. Tap Next and repeat Step 4 to load the white Breakaway PLA filament into
the right nozzle.
6. Clean the nozzles using the tweezers, and tap Both Filament-loaded.
If no filaments are coming out of the nozzles, do not tap Both
Filament-loaded until you repeat the steps above and the
filaments extrude successfully.
To change the filament, take the following steps:
1. Tap Control > Nozzle on the Home Screen.
2. Select the target nozzle, set the temperature, and tap Heat.
3. When the heating completes, tap Unload and pull the filament
out of the nozzle.
4. Insert the new filament into the module, and tap Load until the
new filament extrudes successfully.

How It Works: XY Offset Calibration
The machine will print a calibration model in the X and Y orientations,
respectively. After you have selected the best pair of lines (where the top line is
most horizontally centered on the bottom line) in the two models, the machine
will automatically calibrate the X and Y offsets of the two nozzles accordingly
by making real-time compensation.

* The XY offsets and the best pair of lines in the graphics above are just examples for
better illustration.
Before doing the XY Offset Calibration, ensure that the Print Sheet
is clean.
Every time after you have replaced the hot end, you need to redo
the XY Offset Calibration and Z Offset Calibration: swipe left on
the Home Screen > tap Calibration > XY Offset Calibration or Z
Offset Calibration.
