Hi Mikee,

You can actually wire up all homing switches in series to one (1) input, and mach will know what to do with the order of homing. Z axis, X axis, then Y Axis will follow. The sheilding needs to be grounded only at the control box. The other end is left  undone as not to create ground loop issues.

You really wouldn't even need mechanical limit switches as the soft limits that are in Mach 3 work great.

This is a great help at times, have a look at page 11  ftp://machsupport.com/Docs/Mach3%20Setup%20Tutorial.pdf

Hope that helps,
Dave
