CNC controller with serial (RS232) communication

For USB...

Smoothstepper is popular:

There's also CNCUSB:

LAN interfaces seem to generally be a lot more expensive, some examples here:

I'm sure you'll find more.

To 'get away from Windows timing problems' you could just use EMC2:

That doesn't entirely eliminate the 'problem', but do you need to? Clearly many people use the parallel port, so what are you making that requires a better interface or is it just for convenience?

Hi Jonathan,
I don't requiere a better connection, EMC2 would be fine... But I try to get it working many times, I can't get it control my spindle. How do I get a 0-10V output? (with Mach3 I just use a small board that is control by Pulse/Dir just like a stepper controller).
Also, windows is causing timing issues I am also runing out of space in my tiny workshop, and was thinking of using a mini PC to replace my current desktop. Unfortunatly these do no come with parallel port... :(

I looked at Smoothstepper solution, but it is USA based... Can we get them in UK ?
