Carbide Create pro,
Maybe more than one Roughing pass?
Ran across this recently, I was cutting a 2.5d image into wood.
material, pine, 1.456" thick and a 4"x6" cutting area.
The project was set with a 0.25" relief height (1.2" base).
Using a .25" flat bit for the roughing left some areas that were full height because the .25 cutter would not fit. On the first finish pass I ran a .125" flat bit (0 flute). Now, because the 1/8 would fit through the tighter areas, it went through at Base height (1.2" z from table) through the 0.256" areas as well. … it did the same with each following/smaller diameter bit, just to lesser areas.
I intend to cut much larger 2.5d projects (xxl) and it would be nice to do like a 1" bit for major material removal and then step down in bit size while still in Roughing with the specific amount of material left and then switch to “Finish” paths/bits/angles @ 0 material remaining…?
fwiw, it is a freud “0” flute 1/4 shank 1/8" flat cutter. Makes a bit of sound when cutting .256" with full engagement. no lost steps though.
