OrcaSlicer — K2 Plus

OrcaSlicer is the recommended slicer for the K2 Plus. It has a built-in K2 Plus printer profile with the correct 350×350×360mm build volume and chamber temperature support.

Printer Profile

Select the built-in K2 Plus profile when setting up your printer:

Printer → Creality → Creality K2 Plus

Key profile values:

Setting Value
Build volume 350 × 350 × 360 mm
Kinematics CoreXY
Max speed 800 mm/s
Max acceleration 30,000 mm/s²
Chamber temperature Supported

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]

Keep the start G-code on one line

The block above must stay as a single line per command — START_PRINT EXTRUDER_TEMP=... BED_TEMP=... CHAMBER_TEMP=... all on one line. If your start G-code template has line breaks between START_PRINT and its parameters (for example, pasted from an older guide or edited by hand), OrcaSlicer will render each parameter as its own separate line in the sliced file. Klipper then sees BED_TEMP=60 and EXTRUDER_TEMP=220 as unrecognized standalone commands and logs Unknown command (key61) errors for each one. The print will still run with the correct temperatures from START_PRINT's own logic, but re-slice with a single-line start G-code to clear the errors.

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.
