I'm having trouble calling a subroutine from a separate file.

Ok, got it back to where I was originally.
No, the path is still good.
There seems to be some sort of critical requirements for the %.

This seems to be a bug in 2.8 / master (if you are not using 2.8 / master then ignore this)

If a subroutine has % at the beginning and end _and_ the loaded G-code file has % at the beginning and end then there is a problem.
If either or both use M2 instead then there is no problem. (probably)
