So @PhilJohnson way with the cone works out great. I just couldn’t figure it out at the moment so I tried a different way.
I first attached the laser. Also I used phils laser mount. I used the code M3S10 in the macros section. This macro will bring on laser at lowest power. Put the laser where ever you want and I marked that with a pen.
I then performed my laser g code
I then took off the mount then added my bit. I went with a .0625 bit. (Mine was .059 with calipers). I then put bit in middle of my dot
Then profiled out the piece.
After I had a right angle on my wasteboard. I aligned laser first in corner then slid the work piece underneath and measured the 3" from heat sink
Here’s photo before sliding work piece underneath
After just a little sanding and boom!!! you’re done. There’s prob a ton of easier ways to do it. I just did it this way because of less screw up on my part.
