EStop Out

Hi!
I just retrofitted an old Bridgeport CNC Mill with a new servo drive system. I got it set up with LinuxCNC, and got everything moving well. I'm having issues with the EStop Out feature. I have a normally closed loop run through all the limit switches and my external EStop switch for the EStop In circuit on pin 15 of my breakout board. I have all of my axis brakes run off a relay on pin 14 of the breakout board. I'm trying to set up the configuration so that the brakes come on when I hit the EStop button. In the configurator, I have pin 14 set to EStop-Out. When I launch my machine, I can use the external EStop to activate/deactivate the on-screen EStop, but the status of pin 14 doesn't change. I'm thinking I may have to write some code for the .hal file that takes the EStop-in signal and turns it into an I/O signal for pin 14, but I assumed that's what EStop-out should do already. Any insight or suggestions would be appreciated!
Thanks
Dave

Thanks for the reply. The board is like the one in this kit: www.ebay.com/itm/SAMSUNG-200W-SERVO-PACK...&hash=item3cb57d0fef
Whether I invert it or not, the problem is that the circuit stays either open or closed. I want the EStop switch to energize the relay that operates the brakes, but it won't change.

I just created a minimal configuration with Stepconf and left pin 1 connected to e stop out. I watched the state of pin 1 on the parallel port and it toggles with the e stop button in Axis. So at least that part works.
Next I selected pin 10 as e stop in and Stepconf connected it to the estop-ext signal. I can't test that from my sim...
I use the estop_latch component on my BP knee mill with an external e stop button.
Prior to the estop_latch component AFAIK you had to use classicladder to sync with an external e stop button.

John, I just tried what you said. If I don't assign a pin for EStop-In, I can assign a pin to EStop-Out, and in Axis, I can toggle that pin on/off with the EStop button. Once I assign the EStop-In pin, EStop-out seems to stop working. I couldn't test estop-latch from the HAL Configurator with Axis running, so I'll try putting that in the HAL file and see if that works. Is input 06 your E-Stop In signal?
