I've got Mach 3 sorted except for the limit switches.

I've got 6 limit switches - 1 for each end of each of the 3 axis' all wired up normally closed. 3 of those switches at the -- end I've got another wire connected up to a separate input on the normally open side of the switch.

So effectively I have two circuits each with a separate input into the G540. Normally closed for the limits and normally open for the home circuit.

The homing works so that is fine but I can't get the limit switch system to work. Am I doing something wrong or should I change the setup?

Thanks
Andrew
