Based on the one I did just a week ago:
I thought I’d tive it another shot. Slightly smaller (same piece of wood actually), using a 1/8" bit for rough, and a 90deg v-bit for the finish pass. Pleased with the results:
This measures 9.5x17"
12 min for the rough, and just over 20 min for the finish.
However, the finish pass had a pretty bad failure I was able to recover from (use last home positino did not work), I’m going to start a separate bug thread for that (link below). Because of the finish pass start failure, I had to guess as to where my XY home was (I use a probe for z), and it was off by about 1/16" : because of that the vbit didn’t quite line up with the rough, and a substantial amount of sanding was required
