Re: [CAD_CAM_EDM_DRO] Re: Re: EMC Home and Limit Wiring

the pinout documentation is mostly spread thru the source code
I've pulled some of it out here
http://www.mindspring.com/~pitt/EMC/EMC_docs.html
way down at the bottom of the page is the pinout for the aux LPT port
ESTOP_SENSE is an input on pin 13 to read the state of your E-Stop circuit
ESTOP_WRITE is an output on pin 16 to trigger your E-Stop circuit by software

the E-Stop circuit itself should be hardwired failsafe to function regardless
of what the software does
