Guy Zattau’s Limit Switches Update

“Found my info on limit switches while searching Taig cnc mill on Google. Here is the rest of the story. I just got the switches working and guess what?, they didn't always work reliable. So here is the fix and pics. A piece of brass .350"x.092" filed to a triangular shape, long enough to cut six .170" wide pieces. The top of the micro switch actuating lever and bottom of the brass piece are mildly scraped to make for better adhesion. Clean surfaces and use crazy glue to adhere the piece to the switch. Use a needle to apply a very small amount then once it is stuck add a small amount if there are any visible voids. I  tugged on them and it looks like they are strong. The ramps on the trigger pieces also have to be filed to about 60 degrees and may have to be adjusted for position.”
