Re: [Emc-developers] New tool table format and TLO improvements on master

[Mark <mp...@gm...>]

Is someone going to put in a good error message for when emc2 encounters an
invalid (i.e. outdated) tool table? Perhaps direct the user to a
documentation page on linuxcnc.org.

I'd try to create a script to convert the old format into the new format,
but I'm swamped right now. I'm sure that such a script would be appreciated
by people with a large table.
