    I think you should take a step back and start with baby steps with Lcnc. Start by getting the homing sorted etc.
    I have read your posts on the Linuxcnc forum and seen your ini and hal files they are different to the ones you have posted here try and be consistent with what you are asking.

    I think your limits problem is that the machine does not know where it is, so get it homing first. I know where there is a working config for the 7i76e but it is for a plasma but is near enough.

    edit : And just to keep you sane https://www.youtube.com/watch?time_c...&v=bAdqazixuRY
    The first ini I posted on linuxcnc didn't work I had set up A axis, the one I posted in the quote should have been the same one as I posted here but too early to check lol.

    I've been looking at 7i76 for a little while but was confused on if 7i76 did step generation or you needed the 5i25 combo for step generation.

    I guess what I'm asking is can I get away with buying the Ethernet version of 7i76 on it's own?

    I'll get the switches on today hopefully my M3's have been shipped so should be today they come but I did try no forced homing as well as manual homing which I read should have made this go away but it did not lol.

    When I press - on the manual move buttons for the Z axis should it move up or down? I'm guessing down at the moment mine moves up lol.

    My friend keeps telling me to just use Mach 3 but if I do then I'd set up a pirate see if it works ok do some cuts then buy it and the inner tight guy inside me says just learn linuxcnc you idle twat lol and then the 200 you were going to use for Mach 3 will buy a 5i25 and 7i76 with the saved money ;)

That's how I configured my EM drives, which would allow you to loop through all the fault outputs and create a failsafe circuit.
    I never understood what you wrote the first time but rereading it now it makes a lot sense basically setting the fault output to Normally Open. Basically doing the same as with microswitches setting them NC so if there's a dodgy connection line it will fault.

    This is from the AM882 manual not got mine connected yet did make a cable but lost it lol but have more donor cables and usb to rs232 for the job.

    I wonder if the AM882 software works with Wine if it does I could use the linuxcnc to talk to the drivers which would be convenient but it's nto a major hassle to drag a windows laptop to the drivers for tuning.

    Alarm signal high/low will be it and also interesting I can inverse the AM882 direction in software although I can imagine annoying later down the line when you forgot what you did and are reusing the drivers lol.

    I'm running the stall to the Estop so will need to swap the wiring round on the emergency stop button to NC to match and invert the Estop pin but no biggie.
