On Anet A8 with SKR V1.1 32 bit board my intention is to use 3 extruders on my Anet A8, 1+2 via Y-piece on single nozzle, 3rd Extruder with 2nd nozzle. Need another stepper to connect to SKR V1.1 (10 additional pins are available), extruder 1 + 2 go to single nozzle/heater via a Y-piece, 3rd extruder is on its own with own nozzle/heater. How to modify latest Marlin for this?? Please, all help appreciated, thanks a lot.
The latest Marlin, version 2.0.8, allows for multiple extruders (albeit with a single or multiple stepper motors) through a single nozzle, or multiple extruders with multiple nozzles, it is not possible with the current compiler definitions to configure a mixed extruder nozzle concept; this would require more changes to the sources.
