It may, and in fact I have been considering adding cycles to the debounce routine that is in that path, just to achieve a similar effect. Can't do very much delay though, the copper on the pcb isn't thick enough to take a heck of a lot of that. I am not doing visible damage to it ATM unless I miss handle the gage in placing it on, or taking it off the ways. I need to slap another shelf up on the bottom of the 2x4's that are holding the lathes major tools above it now which should help keep the gage clean(er). Its set at 4 ATM, see "man 9 debounce", and when it errors I can see the led on the C1G flickering half heartedly 90% of the time. When I get it back together with the ball screw we'll do further "adjusting" I'm sure. > John A.
