After searching the various responses concerning the wiring of Homing Switches to a Gecko G540. I'm confused about switches that are designed to be run in a Normally Open Configuration when the Gecko PDF states that the G540 is designed to operate Homing Switches in a Normally Closed Configuration.
Is there a way to modify what Mach3 sees such as changing from Active High for Normally Closed to Active Low for Normally Open?

Config -> Ports&Pins -> Input Signals -> Collum Aktive Low

Thanks for clarifying what I was assuming to be correct.

The problem with active low configuration is, If a wiring fault occurs you wont know until your head crashes into the table or boundaries. Active high is much safer and E-stops if there is a fault.

Not really a problem for homing switches as long as his e-stop and limits are normally closed.

Ok, for a brand newbie, I have the mechanics together(minus the limits switches) but there`s a difference between a homing switch and a limit switch?

Greetings !
There's a GREAT BIG section regarding this in the set-up manual ..... well worth a read, its well written and quite clear. Even for a brand newbie .... like I was. :)
