Good point.
It seems there are quite a few ways you could configure an Idex:
- A Basic tools: T0, T1
- B Mirror, duplicate mode.
- C Tools with MMU: T0 left, T1 right+mmu1, T2 right+mmu2, etc.
- D Duplicate mode with dual MMU: T0 - first filament for both mmus, T1 - second color,…
Would you even want to switch between then mid print? Seems to be no, unless I’m missing something.
My code can support A and C but not the others, def something to consider. This seems to call for a separate idex mode.
Could be similar to colour mixing extruders. Will take a look at the idex PR.
