Hi, RC
There's no limitation that I'm aware of on g-code and Mill,
Lathe, I didn't remember that it wouldn't even post single line code without PRO Lic..
Just some of the Pro features, Pocketing, Offsetting, Foam 2d and Lathe
On a good day I have problems with lathe, Scheduled for a re-make so far back well........
Thanks, Chip
