X axis 0 is far side, Y axis 0 is right (away from feeders) Z axis 0 is top
Limit switch as home switches:
Speed for homing 5%,
X wasnt always backing off enough so Config-> general Config -> Debounce Interval = 20
X zeroed on neg axis is 770.20 to other limit switch
Y is 614.2437 to other limit switch
Z is 190.7469 to bottom limit switch
Config -> Home Limit switches:
Head select is via parallel port pin 16 & 17 linked to PIC18F4610 B6 & B5 respectively
Mach3 M7 (Mist) -> Output2 -> PPort 16 -> 18F4620.B5
Mach3 M8 (Mist) -> Output3 -> PPort 17 -> 18F4620.B6
In Mach3 Output 2 & 3 are tied to parallel port 16 & 17 respectively with spindle setup
