The BEST approach would be to be PCI or PCIe motion card. Eliminate the Eithernet/usb bottleneck control problem.  Tormach has the right idea eliminate the problem to begin with then you do not have to deal with it anymore. There was a reason PC monitors never went USB or eithernet and it should apply to Motion controllers as well.

AND yes Some modern CNCs do run eithernet BUT they also have 2-4 main CPUS to keep it all running together and in sync. We basically have 1.

I wonder if the UC100 can handle the M10/11 commands.

Yes it can. At least according to the manual.

Checked out the manual and it also has torch height control inputs, to my surprise. The big test will be seeing how it actually handles the M10/11 commands and if it can process those commands as fast as a standard parallel port setup.

Here is a video of it laser engraving.

I don't know if that applies to what you are doing but it's pretty cool nonetheless.

Mach 4 pp (Darwin) can do that to

Maybe ??

Although laser engraving is handled well in Mach3 unfortunately Mach4 / Darwin still has some way to go.

Tweakie.
