M32 S5022 !/boats/sailboat.gco pre code post Select and start a file from within G-code. M32 P !/models/lgbust.gco# The `#` suffix is needed when using `P` to "stop buffer pre-reading" so no commands after [`M32`](/docs/gcode/M032.html) will go into the buffer until after it returns.

The M32 command exists to allow G-code to load other G-code files and run them as sub-programs. This can be useful to change the start / end G-code for a batch of files without having to edit them all.

For legacy reasons M32 uses '!' (and '#') to delimit the filepath parameter. The filepath must be the last parameter.
