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


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 (e.g. name, color and type of filament) and the temperatures obtained. You can disable individual heaters and even specify a custom gcode for the preheat phase. The gcode will be executed after the selected temperatures are set.

Further Examples


To quickly switch between different Z-offsets (flexplates with smooth and textured surfaces), you can create presets and deactivate the heaters.

As G-Code you simply enter SET_GCODE_OFFSET Z=0.2, of course with your determined offset.
