Greetings all;
I am rewriting my holefinder routine. I would like to know if a G10 L2
axis's R P1 is exactly the same as doing a touch off by mouse for system
G54? Except for the added R of course.
On the 6040, I have also worked out a 2 pins in parallel method to use
either an electrical touch probe, or that bit of plastic crap that sells
for $70 they sell on fleabay for an edge finder. Both hooked up at the
same time.
Here is a probing routine I wrote for my Blum touch probe.
It does a double touch in each direction, first a fast touch
and then a slower one for best accuracy
(the 2nd touch is so fast you can't even see it), then it
reports the center and width in both X and Y, and moves to
the center of the hole, and goes a G10 L20 to zero out the X
and Y coordinates there.
The 0.1526 is the radius of the probe ball corrected for the
deflection of the probe it requires to trigger it.
