The surfacing bit that the unit comes with is 1.125". It is set to 1.125" in the surfacing step, with a 40% step over.
I did get additional feedback from support, asking that I check the Y1 and Y2 bolt points. There is not any ‘adjustment’ on the X axis, the plates should be completely seated. Even though they appeared to be completely seated, I did loosen and retighten these places. I did see a slight improvement. The very slight ridges are now gone, and even though I still see the lines, that is probably just an artifact of the cutting direction and blades. I think I’m going to look at getting a higher quality surfacing bit, but my issue seems resolved.
I’d still like to see a uni-directional planing option in Easel. There is always one direction that will plane far smoother than the reverse. I need to look into VCarve to see what unidirectional planing options might exist there.
Thank you all for your insights and thoughts!
