Voron Start G-Code/End G Code Example

Created by DREMC STORE, Modified on Mon, 2 Sep, 2024 at 4:41 PM by DREMC STORE

To use our start and end G-code macros, please note that they are based on the LDO Voron kit configuration.

NOTE: NO WARRANTY is provided. This is provided as a guide; please always double-check G-code actions. If you have purchased a Voron kit from us, feel free to email us with your current printer configuration file, and we can offer setup guidance. If you have further questions, please contact support. We can only offer support to our existing customers via email, while service contractor customers can reach out via phone.

Note: Kamp should be installed and working, [Current Below config is tested on https://github.com/kyleisah/Klipper-Adaptive-Meshing-Purging/tree/v0.1.2] You may need adjust KAMP setting to be suitable for your setup.

Note: As of May 2024, if you are running the latest Klipper version with KAMP built-in, you should be able to use it without installing the module. However, if you wish to use the purge line macro, we suggest setting up KAMP without enabling meshing, but enabling either the line or Voron purge based on your preference.

Super Slicer Start Gcode Passthrough [Add to Start gcode in your slicer]

PRINT_START HOTEND={first_layer_temperature[initial_extruder] + extruder_temperature_offset[initial_extruder]} BED=[first_layer_bed_temperature] CHAMBER=[chamber_temperature]

Prusa Slicer Start Gcode Passthrough [Due to Prusa Slicer 2.6 Limitation, Chamber temperature cannot be pushed]

PRINT_START HOTEND=[first_layer_temperature] BED=[first_layer_bed_temperature]

Bambu/Orca Slicer Start Gcode Passthrough[Add to Start gcode in your slicer]

PRINT_START HOTEND=[nozzle_temperature_initial_layer] BED=[bed_temperature_initial_layer_single] Chamber=[chamber_temperature]

If you wish to use secondary bed thermeristor to wait for bed to heat soak example, we use negative 10c offset to reduce the heat heat soak time, but if you wish you can always remove offset of 10c
