Title: Debounce
Post by: william55 on September 05, 2016, 05:34:15 PM

Hi
I have a question about the debounce setting, A few months back I was having a problem with a program running were it would suddenly stop and I would have to reset  and start running again. It was  recommended that I increase my debounce setting because I probably had some ground issues or perhaps something was unsheilded in my wiring. In reading posts since then I have read that some people have these issues and have theirs set at a variety of numbers. My question is how do these affect how Mach 3 runs when you are not at the ideal 0 setting.
Thanks bill

Debounce will slightly delay any inputs that are triggered.
It really should have any affect on running g-code.

I search the forum for my relative issue and also find another thread:

I think, if installing a small (1uF) capacitor between signal pin and ground can help low debounce to do a good job in homing or probing,
that would be a proper way to run your g-code with low debounce value, especially for some potential EMI problem.
