I ran the old CNC router for well over a year before getting around to putting limit switches on it. Since I rarely cut anything which approached the sides of the envelope it really wasn’t a big problem. But I really wanted to get it set up so that I could have Mach3 home it to a known location and have a little more consistency. So I bought a handful of inductive proximity switches and started bolting them on. You can click on the build log link below to see how it went.
