Shapeoko 3 Limit Switch Mounts

thingiverse

My battle-hardened Shapeoko 3 (#603) came with limit switches, but they needed some help. To get them working properly, I had to add 3D printed tabs to the ends of the X and Y axis. There were other options available on Thingiverse, but I chose a more minimalist approach. A full set of these mounts takes about 2 hours to print. Each mount requires one M5 screw and nut to secure it in place. The 3D printed post in a second screw hole keeps everything from rotating out of position. To get started, you'll need to print three different mounts: a Z-Axis mount, an X-Axis mount, and a mirrored version of the X-Axis. You can do this in your slicer or use the mirrored version that comes with the Fusion 360 file. Don't forget to print two Y-Axis mounts as well. When you're ready to install the Z-Axis mount, remove one silver spacer from the backplate. I'm using standard micro switches with roller ends, but you can easily make some adjustments to use non-roller variants if you prefer. If not, just bend the switch arms a bit and you're good to go.
