Hoping someone can provide some insight, because I'm about ready to tear my hair out.

I have a Bostomatic 312, retrofitted with a Sound Logic control board and running Mach3 (done by a previous owner). Everything mostly works well, but I have run into one annoying issue:

Using a 3D probe AND a touch plate.

I want the probe for finding the part origin and the height of the touch plate relative to that, then the touch plate to set tool offsets after tool changes.

The probe is NC and the touch plate is NO.

----

I'll skip all of the various hardware things I've tried (the real answer is that I should have got an NO probe).

But here's where I'm at:

I want to switch the probe input pin programmatically in Mach3 through a macro, so I can simply swap between the two.

The AIs tell me that should be possible, using some variation of:

Call SetInputData(22, 1, 12, 1, 0)

But I've tried that in a million different ways, even reinstalling the newest version of Mach3, and it just doesn't seem to recognize the command. Or even several other commands (like GetEngine).

Does anyone know why? These are commands that the Gemini is confident exist, but Mach3 doesn't agree.

Is there some other way to programmatically switch input pins?
