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.
Each individual canister bay has a material drive block and a drive lever
engage (and disengage) the drive block with the canister. The drive block feeds filament from the canisters to
the 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
positive 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
when material is available to be loaded to the liquefiers.

LED Indicator
There is one colored LED light above each canister. The LED indicates the canister condition for each bay
(Figure
2-17):
•
Green – Steady. Material filament has been loaded into the liquefiers. You cannot remove the
canister when the LED is a steady green.
•
Green – Flashing (Ready state). Filament has been fed into the canister drive block but is not
loaded 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
unload canisters if necessary.
•
Off. No canister is present, or the canister is present but the filament has not been fed into the
canister drive block.
