CANISTER BAY COMPONENTS
The F900 system has four operating material bays - 2 model and 2 support. The upper two bays hold model
material; the bottom two bays hold support material. While building, two canisters will be active. An active
canister has material filament loaded to the liquefiers (steady green LED).
• Inactive canisters can be replace without pausing the system.
E
ach individual canister bay has a material drive block and a drive lever (Figure 2-18). The drive lever is used to
engage (and disengage) the drive block with the canister. The drive block feeds filament from the canisters to
th
e liquefiers.
• The drive block is located above the canister which drives the filament up to the liquefiers.
•
The drive block is spring loaded and moves up and down on guide pins. The spring provides
p
ositive pressure for the drive block against the top of the canister.
• The drive block contains a material sensor. The sensor is used to communicate to the system
w
hen material is available to be loaded to the liquefiers.

There is one colored LED light above each canister. The LED indicates the canister condition for each bay
(Figure 2-17):
• G
reen – Steady. Material filament has been loaded into the liquefiers. You cannot remove the
c
anister when the LED is a steady green.
• Green – Flashing (Ready state). Filament has been fed into the canister drive block but is not
l
oaded into the liquefiers. You can unload canisters if necessary.
• Red – Steady. The canister is empty. You can unload the canister if necessary.
•
Red – Flashing. The canister has a load failure or a smart-spool-chip read/write failure. You can
u
nload canisters if necessary.
• Off. No canister is present, or the canister is present but the filament has not been fed into the
c
anister drive block.
