Mainsail supports so-called presets. They are often used for preheat & cooldown, but also execute normal G-Code.


In Mainsails interface settings you will find a section called “Preheat Presets”. There you can set your presets via “ADD PRESET” and the following dialog.


Enter a name for your preset, such as filament, color or other text and the temperature you wish to set the preset at. You can disable individual heaters and even specify a custom G-Code for the preheat phase. The G-Code will be executed after the selected temperatures are set.

Further Examples


You can add custom G-Code to make it easier to switch between different Z-Offsets. This makes it easier to work with different surfaces and flexplates.

To configure the G-Code enter SET_GCODE_OFFSET Z=0.2, and change 0.2 to the offset you need.
