I have a hicon ingera (the newer black one).
Windows 7 Professional 64 bit
Intel I7
2.8 ghz
The "probe" input is wired to #8 shown in the picture J13 inputs. I unplugged the Relay input for the torch to take a clearer picture.
The probe signal alone seems to work fine. If I activate it, both Mach 4 and the controller board light up.
I tested it repeatedly with nothing but "M03" as the G code.
The torch moves down and as soon as the probe is active, the torch stops moving and mach 4 crashes.
It happens every time.
There is nothing in the history readout at the bottom, and no error messages from windows.
I tried restarting Mach 4, restarting the computer, and using a different input on the Hicon.
Interesting side note. even if I turn the THC off it still tries to probe. I crashed my torch into the table 3 times because of this. After that I stopped trying. Of course I would like to use THC, but I can't even turn it off temporarily to manual set the height. I had to exit and setup another profile to get around the THC function.
