Caution: GRBL Errors with ()

I’ve not yet investigated how wide-spread this issue is, but I’ve found that any post-processor that outputs the toolpath name, if that toolpath includes parentheses ( or ) it will cause GRBL to throw and error because of incorrectly commented comment lines. Seems to be an issue with the default Vectric PP as well as the one I wrote. Might be larger, but take a look at this if you’re getting seemingly inexplicable grbl errors.
