I got this from another post on the forum, added the estop pin from my 7i96 board and it works if I use a normally open switch.
loadrt estop_latch
addf estop-latch.0 servo-thread
net estop-loopout iocontrol.0.emc-enable-in <= estop-latch.0.ok-out
net estop-loopin iocontrol.0.user-enable-out => estop-latch.0.ok-in
net estop-reset iocontrol.0.user-request-enable => estop-latch.0.reset
net remote-estop estop-latch.0.fault-in <= hm2_7i96.0.gpio.006.in
However, my estop switch is normally closed. I tried adding the -not parameter to the end of the pin like this:
hm2_7i96.0.gpio.006.in-not
But when I try to start LinuxCNC I get an error that says the pin does not exist.
What is the correct way to invert the pin so I can use a normally closed switch?
