Machine G-codes

In OrcaSlicer, edit your printer preset and go to the Machine G-code tab. Set:

Machine start G-code: 

SET_PRINT_STATS_INFO TOTAL_LAYER=[total_layer_count]
M140 S0
M104 S0
START_PRINT EXTRUDER_TEMP=[nozzle_temperature_initial_layer] BED_TEMP=[bed_temperature_initial_layer_single] CHAMBER_TEMP=[chamber_temperature]

Machine end G-code: 

END_PRINT

Before layer change G-code: 

;BEFORE_LAYER_CHANGE
;[layer_z]
G92 E0

Layer change G-code: 

SET_PRINT_STATS_INFO CURRENT_LAYER={layer_num + 1}
;AFTER_LAYER_CHANGE
;[layer_z]

Time lapse G-code (if Moonraker Timelapse is installed): 

TIMELAPSE_TAKE_FRAME

Change filament G-code (if M600 Support is installed): 

M600

Chamber Temperature by Material

OrcaSlicer supports chamber temperature per filament profile. This maps directly to the CHAMBER_TEMP parameter in START_PRINT.

Material Chamber temp
PLA 0 (off)
PETG 35°C
ABS 50°C
ASA 50°C
PA (Nylon) 55°C
PC 65°C
TPU 0 (off)

Multi-Material Setup (K2 Plus Combo with CFS)

For the K2 Plus Combo, configure OrcaSlicer as a multi-material printer:

  • Set the number of extruders to match your loaded CFS slots (up to 16)
  • The slicer's T0–T15 tool change commands are translated automatically to CFS slot addresses by the M8200 macro in box.cfg
  • Set flush/purge volume to match your box.cfg settings (default ~140mm³)
  • Purging occurs at the CFS purge chute position (X=133–160, Y=378) — not as a line on the bed

See CFS — Color Filament System for the full tool-change sequence.
