Custom G-Code Variables

MatterSlice allows certain tokens to be placed in custom G-Code that will automatically be replaced with the appropriate values. For example:

M109 S[temperature]

In this line, [temperature] will be replaced with the extruder temperature defined in your slice settings. These tokens can be enclosed in either square brackets [] or curly brackets {}, but for compatibility with other slicers square brackets are recommended.

Here is the list of currently available tokens:
