I have an engraver and (NML-over-tcp) would be a perfect solution. To control engraver over network via Linuxcnc run on computer is not a perfect solution. To have an extra computer for the engraver is neither especially practical. To run real time tasks locally on engraver and GUI on computer over network should work really well. It would also be practical with some remote control to jog engraver in position before starting. For remote control I lake cables, they do not run away or require batteries. A joystick bolted to engraver might be a good solution.
