CNC Z Probe (Customizable)

This is a customizable probe used with common switches (like these: https://www.amazon.com/gp/product/B00MFRMFS6/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1). I had trouble with warped plywood on my 4x8 CNC, and decided to use a switch probe and bed height correction the way you would with an uneven bed on a 3D printer.

It's designed to sit snugly under and around the spindle, with an opening for the endmill. The default settings work for a Makita compact router with a 1/4" endmill, but you can edit the settings in Customizer.
