Hi craig.
Thank you for the long sentence.
I found "Motion plugin probing procedure."
I want to be able to understand.
I also didn't get good results when I tried to simulate "TOUCH" using a manual switch.
I've had success from time to time, so I got the point.
It was successful by pressing and holding the switch.
However,
I don't think this issue is due to a manual switch.
Because, if you look at the behavior of video.
https://www.youtube.com/watch?v=9LvV6iC3zmY1, plobe descends.
2, plobe does not come into contact and stops temporarily at a certain position. (Video 3: 50 ~)
3, Next, it automatically contacts the front, back, left and right.
My situation
1, plobe descends.
2. It automatically descends to "Z measurement position" and mach4 stops. "ERROR: No contact with probe" is displayed.
In other words, I haven't turned on the manual switch, so I don't think the manual switch is the cause.
We would like to thank Mr. Craig for the MPG program.
I reduced the program for the X Y Z axis and attached an LED for the X Y Z axis so that I could see On Off.
