Wow! Who knew that Home Switches were important, lol? So I have a used machine that I purchased and I have been running it w/o having the Homing Switches hooked up. I bought the machine and since it was having BOB/Driver problems I hooked up the brand new Gecko G540 and scrapped the drivers/bob. I've essentially been running the machine by resetting the zeros manually. I often wondered why I would get travel I wasn't expecting. Now I'm beginning to understand Home, Soft Limits and Offsets. As such I'd like to go ahead and wire the Limit Switches that were on the machine to the G540. I have 4 Switches - X Y/A Z and each are the following:

HTM Sensor FCM1-1202P-BRU4

I'm concerned with how to wire these PNP switches into the G540. I'll adding another Power Supply since mine is currently 36 Volt. Can someone give me a definitive answer? I've seen all sorts of conflicting info on the Internet in regard to wiring and the need for resistors, etc.

If I'm reading some of the other threads correctly - I think I might have to scrap these for NPN.
