    Started on a my first real cutting project and made a couple prototypes. I am using poplar wood (soft) right now and cut a series of narrow channels approx. 7-8 mm wide x 6mm deep with a 3mm spiral up bit cutting 3mm deep at a time. I seem to be getting a lot of ragged material let at the top edge of my cuts. Looking to avoid some trial on my part and error by asking for some ideas on what I should try adjusting.

    It may because you are using an upcut but and it is tearing out the wood. Some people use downcut bits to avoid this tear out.

    Down or straight would be much better. See down a lot on laminated or thin cuts.

    Yes. I use straight a lot when cutting wood because I have old router bits.
