Describe your issue:
I am using printermods xchange and would like to switch between the following three with the T command.
1.0.4mm diameter direct extrusion
2.0.2mm diameter Bowden extrusion
3.0.4mm diameter Bowden extrusion, motor shared with #2.
I tried to apply pressure advance on #3 and started printing the tuning tower and got an error.
console msg : Unable to infer active extruder stepper.
Is there any solution?

I have also configured my printer.cfg by reading this topic.
So I was able to switch the extruder with T0 and T1, but I was having trouble tuning the pressure advance.
The documentation also mentions the EXTRUDER argument.
SET_PRESSURE_ADVANCE [EXTRUDER=<config_name>] [ADVANCE=<pressure_advance>] [SMOOTH_TIME=<pressure_advance_smooth_time>]
I missed it, so I’ll give it a try.
