Just finished redesigning and downloading limit/homing switch mounts for my G0704 to my 3D printer.
While Mach3 does a pretty good job keeping track, it's nice to have real physical homing capability.
I'm also adding an adjustable switch for the Z axis that can be set to limit the low end of Z axis travel to avoid vise, fixturing, etc. Initially I was going to put it in series with the E-Stop circuit, but on reconsideration I think I will put it in the Z axis limit circuit.

Nice job Baldric on the slot cover. This is one of the extremely handy types of job for 3D printers. Great for part holding nests for machining or assembly too. Also great for low voltage electrical boxes for switches buttons motor enclosures etc.

Always better to put over travel and homing switches in the drive circuit as the axis can be recovered without to much hassle, putting in a Estop circuit can lead to the axis loosing its way and needing to be recalibrated.

Which is part of why I changed my mind. The main reason though is that with E-Stop, nothing will move until the switch clears, while with axis limits, Mach3 can be configured to allow subsequent reverse axis movement away from the switch.
