Running filament config.g on IDEX in duplication mode

curieos

I have T2 configured as "duplicator" mode, and I'm trying to figure out how to run the config.g for the loaded filament. Since it's configured as a "mixing extruder" with multiple drives, I'm assuming RRF won't allow me to set it as loaded with a filament, but the tools that make up T2 are loaded with filaments. Is there an established way of running the config.g in tpost2.g?

@curieos It's unusual to define two independent toolheads as mixing extruder.
Why not define two toolchains with separate thermistor, heater, fans and extruder?

As a sidenote, I'd use mirror mode instead of copy mode. It eliminates the inertia of two toolheads swaying around...

@o_lampe Unless this is outdated, this is the intended configuration as per: https://docs.duet3d.com/User_manual/Machine_configuration/Configuration_IDEX

T0 and T1 exist separately as their own tools. They are joined together into tool 2, as per the documentation:

M563 P2 D0:1 H1:2 X0:3 F2:3 S"Duplicator"	; define tool 2, "duplicator mode"
G10 P2 X0 Y0 U-320 S0 R0			; set tool offsets and temperatures
G10 P2 R0 S0					; set initial tool 1 active and standby temperatures to 0C
M567 P2 E1:1					; set mix ratio 100% on both extruders

Mirror mode is not always useful. Sometimes you want two of the exact same part, and they are not symetrical.

@curieos said in Running filament config.g on IDEX in duplication mode:

Mirror mode is not always useful

If you use mirror mode you have to set kinematic matrix and the bed coordinates accordingly. Then you can print anything that's not symetrical

@o_lampe Okay, then link me to where I can find out more.

@curieos I found the answer to my own question. https://docs.duet3d.com/User_manual/Reference/Gcodes#m563-define-or-remove-a-tool I can use the L parameter to set which drive to map filament to.
