Greetings All!

I'm new on the zone and a the new owner of a PracticalCNC router table.(yes I've spent all night reading thru that section of this site, :drowning My issues are many, but I have hopes of making this into a usable machine. It sort of is now. crudely.

This machine has no limit or home switches. at all. I understand the basics of mounting and running the wires back, but have little experience or insight into connecting them to the controls or how to set them up. The PC is running WinCNC for a controller. Not sure if there are specific pins i should wire the limits/homes into or if it matters? Based on what i'm reading in the manual and on the zone I need to modify the WinCNC.ini file with parameters for the limits. what? how? I could really use some help here, thanks in advance!
