Great advice. I am going to ditch that idea.

Well, I suppose I need to get smart on changing the kernel...here I thought all computers ran in 'real time'.
This is good info.

That definitely opens up more options for motherboards/processors...and I am starting to think about maybe just building one of these mini-ITX form factor computers to keep it small.

Sorry. Failure of reading comprehension 101 on my part. I think I'm starting to get a better sight picture for the setup I am going for, and surprisingly I think it might be less finicky than I first imagined.

Thank you for the link...this is very critical information for my setup!
I am going to document all of my lessons learned in this journey so that maybe someday I can try a feeble attempt at a build thread titled "CNC Converting a G0704 with LinuxCNC for Dummies Like Me".
