Re: [CAD_CAM_EDM_DRO] Re: EMC popularity, and Parallel port pin configuration

HI Dan,

I think you're looking for the indexes that allow the ports to be overlaid.

ESTOP_SENSE_INDEX = 4
LUBE_SENSE_INDEX = 6


ESTOP_SENSE_POLARITY = 1
LUBE_SENSE_POLARITY = 1

; digital out bits

SPINDLE_FORWARD_INDEX = 9
SPINDLE_REVERSE_INDEX = 10
MIST_COOLANT_INDEX = 11
FLOOD_COOLANT_INDEX = 11
SPINDLE_DECREASE_INDEX = 15
SPINDLE_INCREASE_INDEX = 15
ESTOP_WRITE_INDEX = 8
SPINDLE_BRAKE_INDEX = 15
LUBE_WRITE_INDEX = 15

; analog out bits

SPINDLE_ON_INDEX = 15
