Many thanks to Russ (Overloaded) on Machsupport Forum) for splitting my questions into a new topic.
Anyway, for Hood, a little more background: I have a SmoothStepper, C23 Breakout Board, C22 MPG Interface Board, and an MPG4 Pendant all working fine on MACH 3 Mill, latest lockdown version.
I need another ESTOP switch than the one that's on the MPG Pendant. My separate E-Stop switch kills the electrics power to servos, Spindle, etc. just fine, but it does not notify MACH3 that an Estop has occurred. The pendant estop via the C22 hardware contact works just fine. It kills the electrics and also trips the mach3 reset button. The problem is that I can't simply series the two Estop switches because the C22 notifies Mach3 by software internally, that its Estop button was pressed. While I can series connect the two estop switches to kill the electrics, it doesnt notify Mach3, because the pendant's hardware relay contact is driven by a buffer chip of some sort and the buffer IC is what notifies Mach3 ahead of the relay contact. That's why I'm trying to get the RESET buttion triggered to notify Mach3 when the remote Estop is pressed.. I tried using the open door input but it stops communication with the smoothstepper whenever the input is triggered. Does open door give any kind of Message or trip reset?
In ports and pins, Estop for the pendant is configured to Port2, pin 15 which goes to OEM Trigger#8. If there is a way to configure an additional input to E-stop, that would make it easy. I think the new C32 board fixes this, but there are C23's out there. Thank you Hood, for your help and tremendous blessings to the forum.
