I'd imagine, the 7i76 isn't cheap either. But in thinking what I have now, and having a dedicated encoder interface thats not subtracted from the 21 inputs I have now, I think theres enough to tally a tool changer at some point. But I need to design it first... Something that will swing completely out of the way when not in actual use seems to be the first requirement. Something that is not mounted on the table, unbalancing it worse than it is, is the second need. Pinning the spindle is #3, Running the impact wrench up and down onto the drawbolt is 4th. Home switch for pocket 1, a step switch to count tools going by is #5. And that likely accounts for only half the tally's of a tool changer. jig control I'm now doing with flood/mist. That needs tallied for tool and jig safety. Throw in a tool probe and I've used over half of what I'll have when I'm done with this in the next week or 2. I now have 5 volts on the bob for the 5i25-p2, so next is to edit the show pin list I made earlier today, and edit in the tb number and the pin # number on it so I can cross ref hm2_5i25.0.7i76.0.0.input-00 to TB4-1, yadda, yadda. 96 such cross refs if I can count just whats on tb2,tb3,tb5 & tb6 Only then can I attack the hal file with hopes I can get it right for this new interface, But I've a pan of water on the stove, gonna make some tri-color rotini & sauce tonight. Probably with about 6 oz of ham blended in to help satisfy the carnivore in me. Dee could care less, but that would take some effort she hasn't got left. COPD is relentless.
