I have one of these.
(Except I payed only 19eur for it.)

Everything works fine (as long as you are on the first page in @Mach3 ).
…except the E-Stop button.
Any idea how to find out what key-code that button sends and how to remap that key to e-stop in MACH3?
(I also have hardware e-stop buttons, don’t worry. It’s just that I don’t like having an e-stop that doesn’t work…from a safety point of view.)
