Help with touch off tool setter

It looks like my tool setter is sending two signals, one when it's pressed and one when it's released. If I set the slow probe to 0 and then back to any value I'm getting a different error and not every time. I think a pull-up resistor will solve my problem.

Finally, in case that somebody else has tried everything and nothing is working, the retract distance was too low and the tool's setter switch was not released before the G53 G0 Z0 of the tool touch off routine.

excellent work! yes that will cause that issue but i did not think of it until you mentioned it. so is all working now?

I still have the same problem but, only with the second slow probing sequence. I guess is my switch, I can't find a sweat spot to make both happy. Although the fast is working well enough so, I will leave it as is for now and I will come back later if I have to.

Thanks once again!

if you calibrate for fast probe only, i will be very accurate, mine is fast probe only as i have found that most sensitivity issues come during slow probing.. seems it is something with the way the switch circuit on the platter opens and possibly slides drags in some scenarios causing rapid intermittent contact that triggers errors. I am getting 0.0001"+/- repeatability on mine with fast probe set at 10ipm. and using only fast/single touch.
