if there a support for 2in1 extruder

[gnugu13]

I use two macros for the extruder change.
`[gcode_macro T0]
gcode:
# Deactivate stepper in my_extruder_stepper
SYNC_EXTRUDER_MOTION EXTRUDER=extruder1 MOTION_QUEUE=
# Activate stepper in extruder
SYNC_EXTRUDER_MOTION EXTRUDER=extruder MOTION_QUEUE=extruder
#SET_PRESSURE_ADVANCE ADVANCE=0.3 EXTRUDER=extruder
SET_PRESSURE_ADVANCE ADVANCE=0.42 EXTRUDER=extruder
#SET_PRESSURE_ADVANCE ADVANCE=0.62 EXTRUDER=extruder
#SET_PRESSURE_ADVANCE ADVANCE=0.75 EXTRUDER=extruder

[gcode_macro T1]
gcode:
SYNC_EXTRUDER_MOTION EXTRUDER=extruder MOTION_QUEUE=
# Activate stepper in my_extruder_stepper
SYNC_EXTRUDER_MOTION EXTRUDER=extruder1 MOTION_QUEUE=extruder
#SET_PRESSURE_ADVANCE ADVANCE=0.3 EXTRUDER=extruder1
SET_PRESSURE_ADVANCE ADVANCE=0.42 EXTRUDER=extruder1
#SET_PRESSURE_ADVANCE ADVANCE=0.62 EXTRUDER=extruder1
#SET_PRESSURE_ADVANCE ADVANCE=0.75 EXTRUDER=extruder1

[gcode_macro ACTIVATE_EXTRUDER]
description: Replaces built-in macro for a X-in, 1-out extruder configuration SuperSlicer fix
rename_existing: ACTIVATE_EXTRUDER_BASE
gcode:
{% if 'EXTRUDER' in params %}
{% set ext = params.EXTRUDER|default(EXTRUDER) %}
{% if ext == "extruder"%}
{action_respond_info("Switching to extruder.")}
T0
{% elif ext == "extruder1" %}
{action_respond_info("Switching to second_extruder.")}
T1
{% else %}
{action_respond_info("EXTRUDER value being passed.")}
ACTIVATE_EXTRUDER_BASE EXTRUDER={ext}
{% endif %}
{% endif %}

[delayed_gcode activate_default_extruder]
initial_duration: 1
gcode:
ACTIVATE_EXTRUDER EXTRUDER=extruderOrca Slicer also transmits the corresponding extruder_PRINT_START_PHASE_INIT EXTRUDER=210 BED=55 MESH_MIN=180,165 MESH_MAX=209,194 LAYERS=1 NOZZLE_SIZE=0.4 TOOL=1in the clipper macro start_end.cfg I have under _print_start_phase_init following insert:{% set TOOL = params.TOOL|default(0)|int %} ; Get tool from slicer

Activate the correct tool/extruder 0|1

T{TOOL}
A debug statement also shows me this correctly. M118 TOOL Value : {params.TOOL}`
But when purging, the extruder T0 is always used
Where could I correct that. I am grateful for any help
