Retrofit an Emco Compact 6P-CNC

This may be a stupid question, given LinuxCNC's capabilities, but I don't know ( having only done mills so far with it ) so I will ask - what about controlling the pneumatic spindle draw bar and tail stock ram? Thanks.

Usually that is done in Classicladder or M1xx. Take a look in the M Code section of the manual for M1xx. John

Thanks John. It's looking like I might be forced to do this project. I just removed a nice Hoffman box from one of my mills when I installed a VFD box, so now I have an almost perfect enclosure for the control that will fit nicely on the side of the actual machine, keeping things tidy. I'm thinking I can put the monitor and keyboard on an arm. With a little scrounging and some luck I might be able to break even except for the time and headaches getting back up to speed on ... ... oh, hey, it's called LinuxCNC now... I guess it's been a while for me... Ha. Anyway, I'll sell off the present contol's pieces and parts and it's looking like what I will need to purchase might come to about $600 - $700.

Well... here we go... I'm gonna have a lot of questions and need a lot of hand holding... I'm guessing that for the most part I should be posting those in the Lathe forum?

I'm very newbie on linuxCNC, actually i'm trying to retrofit an emco120 lathe. I have problems compiling/installing .comp:

How to do that?

OK, let us back up a bit.

If you open a terminal and type

uname -a

what is the output ?
