Stupid problem here!
The Stop Start Reset keys have stopped working on our Rover 23 (xnc cni)
Attachment 484668

They got always more difficult to use and now they do not respond at all.

Is there a way to use the CNC Router without these keys? Can we do a software emulation or is there a shortcut on a standard ps/2 keyboard?

Any help would be appreciated, currently the machine is unusable because of 3 broken keys.
