Help please. Dip switches and mach 3 settings

[cropwell]

I use inductive proximity sensors for home switching, but a micro-switch for limit like this

The inductive sensor triggers off the aluminium of the gantry, but the micro-switch is tripped by a plastic wedge, which allows me to adjust the trip point.

Separate pictures as I can not move the gantry at the moment as I am installing a new mains switch panel for the computers and CNC.

There is one lesson I learned early on - do not have the proximity switch triggered by movement axially toward the switch, once you crush the end it is f***ed (rendered inoperative permanently), make the movement across the face of the switch. If you mount the switch on the gantry, you will only need one switch to sense at both ends of travel, by putting metal targets (preferably ferrous) at the appropriate places.
