Spindle Laser & Probe

To make these files, open up Note Pad and copy and paste the below text into 2 different files. 

There are NO SPACES BETWEEN LINES

Then Save as a TXT file type. Make sure you spell and Capitalize these correctly.

This is for the Genmitsu 3018 Prover V1 - you may need to modify these settings for other versions
