External ESTOP trouble was created by Billy Boy
Hi,
I am retro-fitting my 1968 Bridgeport Series 1 Papertape NC machine with rpi5/Mesa7i96s/Gecko203v.
I've got everything working pretty well it seems, except for the ESTOP.
I have (and want) an external/manual ESTOP-in button. It is currently setup Normally Closed and appears to be successfully plumbed through to the GUI, which is to say that the GUI ESTOP button tracks the status of the hardware ESTOP-in button perfectly.
The issue is that my ESTOP-out is no-longer tracking either the GUI ESTOP or the hardware ESTOP-in. It just stays asserted all the time with no change of state.
To be clear, before I attempted to plumb in the hardware ESTOP-in button, my GUI ESTOP was correctly plumbed through to my ESTOP-out so that it would allow me to disable the steppers.
Aside: I have not been able to find any documentation that really explains how ESTOP is expected to work? I'm unclear on if I should work with estop_latch or not? The estop_latch documentation is also pretty thin and does not appear to include any examples for either simple or complex configurations?
Here is my current configuration... (generated by pncconf)
Thanks,
B

If using Axis GUI (other GUI's may also have this), use the "show hal configuration" from the machine menu to see if the hal stuff is working correctly, on the left side choose the pins to watch on the right side, then toggle e-stop and see what toggles and what not.
