That's neat Ed.

One thing that Marcel should have mentioned in his posts is that once you make one of these cubes, all your friends that see it want one too.
So making just one is no good, you have to make lots.

I think that we all deserve to see a routed or engraved 'Road Runner' after all this. Come on WAC make something real good.

Me too, glad you have resolved the problem.
I expect to see postings of stuff you have made with it now it is working OK.

The nice thing about this forum is that although there must be a million possible causes for any particular problem, everybody is eager to help and sooner or later the answer to your problem will be found.

I think Zafar is to be commended on his use of Mach. We all know how good it is but it takes a lot of (I don't know the best word to use) 'flair' to apply the program to an unusual application.

Well done Zafar.

ACTIVE LOW is what I have suggested.

To follow my circuit recommendation you will need to use the n.o. switch contacts (or replace the switches if they only have n.c. contacts available) - the switches only close when the limit is reached.

A problem with raising the debounce is that the switch needs to be energized for the debounce interval to be recognized by Mach as a stop and by then the machine may have traveled to the mechanical stop position (crunch).

Just a thought Zafar, does that mean 700 tractors a day ?

The basic circuit I have in mind would look something like this.

Change your limit switches AND e-stop to active low. Reconfigure Mach input signals accordingly. (You may need to use pull up resistors to +5V (not +12V) on each of the limit switch and e-stop inputs).
