Proximity switches or limit switches

[JAZZCNC]

Thank's, cropwell so you have separate switches for homing and limits? From what I've gathered you can use the limit switches also as home switches (the home command initiates the desired directions of each axis). Is your design based on increasing safety / reducing risk of damage to the machine? As in the limit switches are placed slightly beyond the position of the home switches.

The main advantage of using separate Limit switches is that you are protected while Homing. When the switches are shared for both Homing and limits then Limits are Ignored While Homing so it's not quite as safe.
That Said the advantages of using Shared switches, Esp if you use Single switch that travels with axis and searches for Targets at each end of travel is much simpler wiring with less chance of wiring errors, Also lower costs.

Regards which switch type to use then it's a personal choice. My personal preference is the Proximity switch because they are accurate and cheap. Also simple to mount.and don't have some of the issues mechanical switches can have.
