V1 Setting V2 Setting Description
If set to true, automatically plays the on_boot_gcode file when the board boots up, useful for automated startup routines like homing or initial positioning.

Path to the G-code file to play when the board boots. Default is /sd/on_boot.gcode.

Useful for automating startup tasks like homing the printer or setting initial temperatures.

G-code to execute automatically right after a suspend command is received. Use underscores (_) instead of spaces in G-code commands.

Commonly used to retract filament and move the toolhead away from the print.

Example: G91_G0_E-5_G0_Z10_G90_G0_X-50_Y-50 (retracts 5mm, raises Z by 10mm, moves to safe position).

G-code to execute automatically after a resume command but before resuming the print. Use underscores (_) instead of spaces.

Generally not needed since resume restores the previous state automatically.

Example: G91_G1_E1_G90 (extrudes 1mm to prime the nozzle).

Controls heater behavior during suspend.

  • false (default): heaters turn OFF on suspend and back ON on resume.
  • true: heaters remain ON during suspend.

Set to true for short pauses to avoid waiting for heaters to reheat.
