Aluminium Profile Type Router - Initial questions

Hah! Yes, "Unless you're going down the linuxCNC route in which case I have no idea" :P

Reading it back it sounds like I'm saying don't use ethernet with LinuxCNC - it was meant as an "if you're using LinuxCNC there may be more appropriate options like onboard PCI cards".

I have a mesa PCI card I don't use at the moment but there is a rare problem with MESA PCI cards when installed in some machines will not boot.

I traced this to a PSU issue, I swapped 3 motherboards into that case before I realised it was the PSU that wasn't letting it boot. The Mesa people told me it happens in 1 in 100 machines.

As soon as I swapped the PSU it booted fine but I had to move the machine so I bought a standalone controller and put it on a catering table with wheels.
