I was asked to provide settings I used to make this project.
I used select pine from Home Depot, which I planed to be exactly .5"
I used speed: 130, full power, with two passes. I probably could have increased the speed quite a bit because of the second pass, and I did get a bit of excessive burning. The single pass at speed 115 was not perfect at completely cutting, so I added the second pass.
I have had really good success with planed cedar and the standard .5" and .25" poplar from home depot.
Cedar - Speed: 128, full power, 1 pass
1/2" poplar - Speed: 125, full power, 1 pass
1/4" poplar - Speed: 168, full power, 1 pass
