I'm using the switches that were used with the old Dynapath system. They were wired to be normally closed but the new system required that they be normally open. The switches are universal so that was an easy change. All of the limit switches are connected in paralell and tied to pin#10 and ground. The home switches are common grounded and wired individually to pins 11, 12, &13.
The switches in mach3 are set to active high, and none of the limit LEDs are on while the blocks are off the swtiches.
XML is attached.
Thank you for your help,
Eric
