Thanks Hood.
I took Vcc and GND from the BOB, and it's getting them directly from the PC's power supply, so I don't think switching this to the USB would change anything, or am I wrong?
I did not check the BOB outputs yet, I don't have the oscilloscope here, but I might put a LED or something to see if there's a signal. And I think I have some sort of LPT "sniffer" installed, so I could use that, too, to see if LPT is getting signals or not.
What I don't understand, however, is, shouldn't the change be visible on the DROs in the first place? I mean, if Mach doesn't register the MPG input and doesn't react accordingly, change coordinates, I guess it most probaly doesn't send anything to BOB either?
Or am I miissing something here, wouldn't be the first time;)
One more thing, I remember seeing somewhere that the pins had to be specified as inputs specifically, but I couldn't fint anythig alike in the Mach, maybe that was in some other version. Just a thought, in case I failed to setup something trivial...
