Try and try as I might adjusting debounce does not stop this phantom limit signal. I have tried 500, 1000, 3000, hell even 10000 I still get the random signal. I have hooked up all of my limits to the oscilloscope and tested with everything from 1mv to 5v and time from 10ns to 1sec. I get nothing no peaks, no random ac nothing. What do I need to do? It's driving me nuts and ruining my peices. I have only run a few things as I'm just getting it running and learning it but this sucks, lol. I have two ports one is the onboard and the other a add on card and all inputs are on the add on card. outputs are on the lpt 1. If I disconnect the db25 cables I don't get the limit signal.
Ok folks. Thoughts?
