1610 CNC Optical Zeroing System

If you own a CNC mill without automatic end stops, you've probably had to restart a few jobs from the beginning because you over-ran where your end stops would've been, or you did something that set off your CNC mill's alarm. This optical alignment tool will help you get back on track from where you made your mistake rather than forcing you to start over by allowing you to manually re-zero your CNC using a cheap USB microscope you can mount to your CNC mill.

Parts Needed:

* A 12mm diameter USB microscope. I bought [this one](https://www.amazon.com/gp/product/B0184CCOY0/ref=oh_aui_search_detailpage?ie=UTF8&psc=1) for another project a while ago. and share it between that other project and this. You may be able to adapt this part to fit other microscope designs, but although the above-linked product is no longer available, there are, at present, several other identical microscopes available on Amazon:
