Limit switch mounts for Shapeoko by zorlack Feb 24, 2014

Description

I'm in the process of adding limit switches to my Shapeoko. Limit switches are nice because they give you two things:

1) They give you some added protection against driving a carriage off the end of your machine.
2) They give you the ability to set up an auto-homing routine. Auto-homing can be very helpful when you're doing a lot of repeat cutting against a fixed jig.

I found this [5-Pack of limit switches on Amazon](http://www.amazon.com/gp/product/B00DN7Z67E/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00DN7Z67E&linkCode=as2&tag=zorlackcom-20) for less than $5. That provides more than enough limit switches to set up an auto-zeroing system.

The mounts nestle inside the makerslide. The two holes should be tapped for M5 screws and bolted to the end-plates. [This document](https://github.com/grbl/grbl/wiki/Connecting-Grbl) describes how to connect limit switches to grbl.

**Edit**
Small change: added a third hole to allow for mounting on the y-axis end-plate.
