M600 Behavior with Dual Extruder

[eacmen]

Model: A350 with Dual Extruder

Scenario: Want to be able to change filaments mid-print using M600 g-code at a specific layer to allow for printing with greater than 2 colors.

Issue: On the single extruder this g-code worked to be able to change the filament color mid-print. If you inserted an M600 command in your g-code, the print would stop and the controller would think there was a filament runout event. When using M600 with dual extruder however you are presented with the single extruder load/unload screen so you cannot change the filament on the right nozzle.

Expected Behavior: When M600 command is triggered in the g-code, the hand controller would go into the dual extruder load/unload menu allowing independent loading and unloading of filament of either extruder in the event of a filament runnout.

Repro Steps: Generate g-code as normal, then edit it and insert an M600 gcode command somewhere in the print.

@eacmen have you tried using M600 T1? According to the repo Snapmaker is Marlin based.

Marlin Docs reportedly show there's a target extruder parameter. Presumably omitting the parameter defaults to an effective command of M600 T0 for the left extruder.

I was going to try this out myself but ultimately modified my print to not need the filament swap on the right extruder. Hopefully it works for you. Lemme know if you'd be so kind.
