@koconnor Has the TUNING_TOWER command been extended to accept an EXTRUDER= value?
I validated that switching to second extruder and adjusting Pressure Advance command with will allow printing to proceed without receiving Unable to infer active extruder stepper:
Updated gcode:
# deactivate stepper on extruder
SYNC_EXTRUDER_MOTION EXTRUDER=extruder MOTION_QUEUE=
# activate second stepper
SYNC_EXTRUDER_MOTION EXTRUDER=belted_extruder MOTION_QUEUE=extruder
SET_PRESSURE_ADVANCE ADVANCE=0 EXTRUDER=belted_extruder
When running a PA test with TUNING_TOWER COMMAND=SET_PRESSURE_ADVANCE PARAMETER=ADVANCE START=0 FACTOR=.020 will fail with Unable to infer active extruder stepper.
There is no updated documentation regarding TUNING TOWER and I did not see any extension in tuning_tower.py for specifying an extruder.
Thank you.
