I'm not sure a wizard exists to do exactly what I want.
I want to use a webcam to jog/align my cutter over a known pcb coordinate/mark then let mach 3 know the coordinate - obviously the camera is going to be offset from the cutter tip...so there's one offset that I need to cater for!
Next, I want to jog to another known cordinate - align the webcam over it, then enter these known coordinates ....and then Mach3 magically updates itself to reflect the fact that the pcb is not squarely mounted.
Now if I had a clue about how to approach this then I would...where's a good starter for learning how to do this? (would it be a macro - language?, a wizard...what would be the best approach here?)
I seek to do exactly via Mach3 what this guy is doing here....

I'm surpriseed there's not more call for this type of thing - lots of folks etch their pcbs, but still need a way of cutting them out - presently it's a major time sump registering/aligning the pcb with the CNC software (not a problem of course if the whole board is isolation milled, but I'm talking for boards with track widths beyond the capabilities of my modest machine hence chemically etching)
