CANISTER AUTO CHANGEOVER
Auto Changeover allows you to leave a long part build unattended. When an active canister becomes empty:
• The system is paused and the canister drive automatically withdraws residual material from the
s
ystem.
• Material is then loaded to the head from the full canister.
I
f an error occurs during the Auto Changeover process, the system will remain paused.
• The System Log Button will show the cause of the error.
•
Once the error is resolved, select R
esume on the Operator Touchscreen to continue building
the job.
HANDLING/STORING CANISTERS
Each canister holds 92 cubic inches (1510 cc) of filament material. The canister also contains desiccant material
to absorb moisture. A removable plastic cap and a thumbwheel door provide an airtight seal to keep moisture
from entering the canister while stored.
If a canister containing material is removed from the system, or remains in the system in a non-ready state (LED
i
s
OFF), it should be stored as follows (refer to Figure 4-39 for referenced item numbers):
1. O
pen the thumbwheel door (item 3) and insert the square foam gasket (item 7A) (stored on the
c
anister - item 7B) into its thumbwheel door location.
2. Close the thumbwheel door - make sure that it is completely closed.
3
. Remove the plastic cap from its stowed position (item 6B) and insert it into the filament outlet
h
ole of the canister snout (item 4 and 6A).
4. Store canisters in an upright position, do not lay them flat.
Note: If the material to be loaded is not the same as the material it is replacing
the auto changeover will not occur and the system will enter the
Pause mode.
Caution: How material canisters are handled and stored has a direct impact on
part build quality. Like most engineering plastics, the filament within the canisters
can absorb moisture. Filament moisture causes poor model surface quality.
Caution: Make sure that you insert the square foam gasket under the
thumbwheel door and place the plastic cap over the filament outlet hole when
storing a canister. In less than one hour, in an unsealed canister, filament can
absorb enough moisture to become unusable.
Note: When the filament is in a ready or loaded state (flashing green LED or
steady green LED), and the canister door is closed, the system air-dryer system
constantly purges moisture from the canister.
