Here is my problem.
I'm adding a camera to my router for edge and centre finding. The traditional way of mounting the camera is in a custom made holder which you insert into collet. For me it is just too much messing about. I can mount a tiny laptop camera behind my Z axis permanently and I could then calculate the offset in the Y direction (X offset would be zero) and input it to the DRO directly.
What i'd like to do is to just click a button onscreen and it work out the offset automatically.
Anyone have experience of programming Mach screens who would be willing to give me some pointers?
Nothing is foolproof......to a sufficiently talented fool!
