    Gotcha, thanks. Manual moving is not really easily done but I’ll look at the other option. It’s not a huge deal to reset twice – I just wanted to make sure I wasn’t missing something easy.

    Sigh…

    Well at least they are only about $35. In fact, I wonder if the same company has one I can borrow… 🙂

    On a side note, when I was playing with my limit switches, they would stop the axis when it hit the limit (input goes… low?) but then I’d reset and jog away and it would trip again when the switch turned off and the signal went the other way. Then I’d have to reset again. Is that normal or is there a setting I’m missing? There’s a ton of settings like this in the homing section but are there separate ones for limit switches?

    Thanks for all your help!

    I just had a thought – and I’m kind of embarrassed it took me this long to think of – but one of the businesses I have a relationship with is an electronics and motor assembly shop! That means I could just have them replace the ATxMega chip with all their fancy reflow, pick and place type stuff! I showed the boss a picture of the board and he said yea, no problem!

    The chip is $10-ish on digikey. I’m going to check the resistor and capacitor for that input tonight to make sure they aren’t the culprit and that’s the only other path to ground I can find.

    Any reason this wouldn’t work? Is the firmware stored on the ATxMega chip or somewhere else? Will a new chip just be plug ‘n play?

    Yea I’ve looked through the schematics but I’m not great with those. The weird thing is all the other inputs work, and yes, the Xmax still “works” just ONLY with the PNP switch and it only triggers after the switch is released, not when the contact is first made. BUT if I try just connecting a wire from ground to Xmax; nothing. Doesn’t trigger at all. It’s like it got used to +30v and now won’t work with anything else…

    Is there a way to use the A axis inputs for as the Z axis? I won’t need the A for quite some time and could make this work for now if I could.
