G49 “Cancel Tool Length Compensation” should be made optional and not hardcoded, also the new G43 H* command will wipe out the values from the dynamic tool compensation… this is evil and it just signed my milling table with a hole in it (it’s a cheap small one so it’s no big deal at least)

Sliptonic gave me a hint, this can be fixed with some post processor flags.

–preamble ‘G17 G54 G40 G80 G90’ --no-tlo

This seems to work with the post processor flags. Thanks.
