I had good success cutting .325" thick white oak.
Cut: 140 speed, full power, 2 passes
Engrave: full speed, 95 power, 270 lpi
Score: 129 speed, 11 power (same as PG maple)
Took a few attempts to dial in the cut. 150 speed was ever so slightly too fast and didn’t cut through consistently. 140 did the trick. Now I just need to sand and finish!
