Virtual (shadow) drives

Nuramori

I was hoping (looking) for a way to effectively create a virtual variant of a drive, so that the same motor could operate under different settings, but be used as effectively as a different, addressable drive. for instance, if we had in our config.g file the following:
...
M584 E0.6
M569 P0.6 S0

M563 P0 S"main filament" D0 H1 F0
...

that I could also then make a shadow version of the one motor to for all intents and purposes be driven as a different motor when associated with another tool (printhead), like so...

...
M584 E0.6:0.6!
M569 P0.6 S0
M569 P0.6! S1

M563 P0 S"main filament" D0 H1 F0
M563 P1 S"support filament" D1 H1 F0

I'm looking for a way to design something to use one motor, but operate in reverse when set to be a "different" head.

Can't you just define two different M569 in the tool change macros?

Nuramori

@o_lampe hmmm, can you modify the motor on the fly like that? if so, then I think that would work.

@dc42 said, I could change the whole kinematic model 'on the fly', so it's worth a try..
Some parameters can't be changed mid-print, it would be nice to have a table about those do's and don'ts
