@tcmoore87 said in Firmware retraction for single tool in multitool setup?:

So that being said I cannot "uncouple" the extruders from the tool while mixing for the purpose of retraction and would need to use each extruder as a separate tool and thus would change my mind about this setup and may go back to the 4 separate nozzle I had before. @deckingman Thank you for your help so if I confused you with what i was asking.

Read my post above because I might have an answer. But "normal" slicer retraction should only retract one filament (although it's a long time since I used it).
