Make sure to load the provided black PLA filament into the left nozzle and the white
Breakaway PLA filament into the right nozzle, which is required to print the test model of
Snapmaker Luban in later sections.
If the filament has a bent or curled end, cut it off before loading.
To change the filament later, take the following steps:
1. Tap Control > Filament.
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.
2. Z Offset Calibration & Heated Bed Leveling
Brief Introduction
The Dual Extrusion Module features a smart sensor that can be used to automatically level the build plate and
adjust the distance between the two nozzles and the build plate. In this way, the machine ensures both nozzles
always extrude at a proper and consistent height throughout the printing process to avoid poor first-layer
adhesion, build plate abrasion, and collision.
How It Works
In the Z Offset Calibration, the two nozzles will move in turn to obtain the Z-axis height of the module when
the nozzle just touches the build plate. In the subsequent Heated Bed Leveling process, the left nozzle will
repeat the above steps at specific points on the build plate to obtain the whole flatness data. With the collected
data, the machine will make real-time compensation for the build plate undulations by adjusting the Z-axis
movements of the module during printing.

Do NOT touch the nozzle with bare hands during the filament loading process, as the nozzle
will be heated to an extremely high temperature.
