A guy local to me has  a Mini PC  Win 10 Pro 4Gb memory, 64 Gb storage,  with room for ssd. Atom processor? Will this run Mach4 with USB PMDX board? I have the  PMDX board installed in my control box, tested and working on my Mac Book Pro parallels with Win 7.

See if he will let you load the Mach4 demo on it and play around.

Video graphics being slow is the most likely consequence of an underpowered PC.

Hi,
my machine run ons a dual core Atom mini-ITX single board PC with on-chip graphics. It wouldn't 'pull the skin
off a rice pudding' yet it runs an Ethernet SmoothStepper and Mach4 very well.

The only time I notice the low power of the CPU is when I go to load large files, say 5MB or bigger. It takes quite a while to
load and draw the first tool path, thereafter its fine.

Mach4 is not  a hungry program, even a very modest PC will run it fine. Don't waste money on a 'you beauty' PC, you'd be better
off spending a bit more on that next spindle....or tools....or servos...or ballscrews ...or....

I don't know about PDMX - but I'm running Mach4 on an intel Compute Stick.  It doesn't get much more 'mini' than that!  It's just a little bigger than a typical USB Thumb drive.

I really didn't expect it to work - but it runs beautifully!

While it only has USB (one USB2 & one USB3), I have it connected to a USB Ethernet controller to talk to a CSMIO/IP-M motion controller.
