36 Operation
Unload material cartridges:
1. From Idle (or Ready To Build), Press Material Load.
A. The panel displays Load Material and prompts with,
Replace model?
• Press Yes. to unload the Model Material.
The panel displays Replacing model,
• Press No if you do not wish to unload the model
material.
B. The panel then prompts with, Replace support?
• Press Yes. to unload the Support Material.
The panel displays Replacing support,
• Press No if you do not wish to unload the support
material.
C. After you have made the above choices, the panel displays
Unloading for approximately 2 minutes (the selected
materials will be unloaded from the extrusion head).
D. When unloading is complete, the panel will prompt you to
remove a cartridge based upon your choices - i.e.,
Remove Both Cartridges, Remove Model (Top)
Cartridge, or Remove Support (Bottom)
Cartridge.
2. Remove the material cartridge(s) by first pushing it forward
gently, and then pulling it out of the slot.
• When you remove a cartridge there will be approximately
213 cm (7 feet) of filament that will need to be pulled from
the system. (This is normal. Material is only retracted from
the extrusion head during 'unloading'.)
3. To store a partially used cartridge, place a small flag of tape on
the filament near the cartridge. Cut off and discard the
remaining material. The tape flag ensures the filament does
not retract into the cartridge.

Do NOT try to rewind the filament that
remains in the system. This will cause
material to cross-wind in the cartridge
causing cartridge failure.
