Unfortunately not. My hardware is set up as follows. A DPST Mushroom ESTOP with NC contacts. One set controls HV power. The other runs a signal into the DB25-PIN10 input for signalling ESTOP to the system. I've added a relay, controlled by the PC Charge Pump, that opens when there is no Charge Pump signal. The relay is in series with the ESTOP switch that controls HV power. So crash/stop LinuxCNC or even just while booting the PC, HV power is not possible. Only after LinuxCNC is running and producing the Charge Pump will that relay close, and of course if the main ESTOP switch isn't pressed, will I get HV power. The trouble is the RED ESTOP Button ICON appears to be a reflection of the DB25-PIN10 input and doesn't appear to act like a toggle switch contrary to documentation that the F1 key (and the icon 'toggles') the ESTOP. And changing various parts of the HAL signals and pins mostly just creates a loop that once the ESTOP is ON and shown on the screen as pressed, it's impossible to unpress it. At that point only stopping LinuxCNC and restarting pulls me out. I have spent hours looking through the various HAL file tutorials and manuals. Can't figure out what I'm doing wrong.
