One of the greatest addition to the Orca Slicer is the ability to handle Craftbot 3 and FLOW IDEX printing modes.
Now you can coose the needed mode under the printer selection
Normal mode:
Printing with the left head the buildplate minus the right head exclusion area can be used.
Parallel mode:
Same object will be printed with the two head same time.
Mirror mode:
Two mirrored object will be printed. Center line is excluded avoid collision of the heads.
Backup:
Craftbot printers can use the right head as a backup. If the filament runs out or stuck in the head the printer will switch to the other head automatically and continue the print with the right head. It can swap back and fort between heads making the print secure and can continue endlessly.
