I have problem with that the printer doesn't use the right extruder. I have mixed with the START_CODE and have several strange problem. When passing settings from Cura with:

START_PRINT

EXTRUDER={material_print_temperature_layer_0} EXTRUDER1={material_print_temperature_layer_0} BED={material_bed_temperature_layer_0}

it doesn't' set any temp except the default and it doesn't use the right extruder even that it is set in Cura to be used and even the left is set to zero degrees. It starts printing with the left extruder and doesn't care that it is cold.

​

Macro START_PRINT:

[gcode_macro START_PRINT]
gcode:
{% set BED = params.BED|default(60)|int %}
{% set EXTRUDER = params.EXTRUDER|default(0)|int %}
{% set EXTRUDER1 = params.EXTRUDER1|default(0)|int %}
M140 S{BED} # Don't wait.
M109 S{EXTRUDER} # Set and wait for nozzle to reach printing temperature. Wait.
M109 S{EXTRUDER1} # Set and wait for nozzle to reach printing temperature. Wait.
G90 # Use absolute coordinates
G28 # Home the printer
# Z_TILT_ADJUST # If it needs to be done every time.
CLEAN_NOZZLE
CALIBRATE_Z
SET_GCODE_OFFSET Z_ADJUST=0 MOVE=1 # Sätter en offset för aktuell print och gäller båda extruders.
#BED_MESH_CALIBRATE # If a new bed mesh needs to be generated every time.
BED_MESH_PROFILE LOAD=default # If you are loading an existing mesh:

G0 Z10 F3000 # Move the nozzle near the bed

​

This is something that shouldn't be set in the start_code since it changes over the whole print. So why doesn't it do that?

I'm so close buying Bud Light soon just for punishment and that isn't good!
