Is there a way to connect up an external E-Stop without using Classicladder?
Thanks

This seems to work ok. You still have to toggle F1 after clearing an external e-stop. The pyvcp checkbox simulates the external e-stop switch.

I seem to remember that the estop_latch comp replicates the 4th ladder example here wiki.linuxcnc.org/cgi-bin/wiki.pl?Sample_HAL_And_ClassicLadder
iirc - I actually tested it for someone...

Hi Sam
Here is the code you linked for me (for lurkers).
I added a not to the external estop so on is not a fault as is normal with estop chains.
Thanks
John

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 resetestop iocontrol.0.user-request-enable estop-latch.0.reset
(and you would have to hook estop_latch.0.fault-in to your external estop.) I added a not to the external estop so on is not a fault as is normal with estop chains.
Thanks

Hi John,
On my joypad I just use..
# joypad estop button
net estopbutton input.0.btn-base3 => halui.estop.activate
As the button is just a monetary contact.
