Quick update… Thank you @jeffeb3’s and @vicious1’s, your settings wisdom and offset tip engraving bit suggestions, they helped guide me to better results. Ended up not needing the Bowflex Dumbbells, for now.
Vertical test lines on the right were created using 1/8" 60deg engraving v-bit, then going over again with 1/4" v-bit helps get wide v cuts. This was with the 4 flute 1/4" v-bit I have already. Hoping the arriving 2 flute v bit and curved bits will do even better.
Seeing pear drop like deeper holes near where the bit plunges at beginning of a path, still need to tune Z feedrate, depth of finish pass, maybe other settings too?
