In the mach3 manual it is mentioned that you can use a keyboard emulator for your limit and home switch, unfortunately they do not explain how to do it I have tried many thing and I just can't figure how to do it.
I tried keygrabber provided with mach3 so i can assign a function but there is no function for the limit switch and home switch.
the keyboard emulator I have is a GP-Wiz from groovygamegear I reused from an old arcade project.
I do know there is a delay using a keyboard emulator but it mostly for testing and I am a bit short on input pin on my breakout board.
ok found my solution :P
for some reason on my cnc machine there was no emulation option on the port and pin setup, reinstalled the latest version and now everything is there o.O
