I really hat e to be the dumb one on this site but sometimes you just have to swallow your pride and ask for help. I've been away from CNC for some years now. And I really wasn't that into it back then. I've purchased a CNC mill and have no idea how to run it. I'm working on getting some info on how to use Gibbscam but wanted to ask you guys for some help on the CNC language. What do they mean by post? Dongle? And any other thing you may can help me with would be much appreciated. Thanks, Mark.
