Info on my One Ring Escutcheon:
Cut: speed 200, power 70 - didn’t quite get all the way through in some spots, but I was able to pop it out easily. Will probably go up in power and/or down in speed a bit next time.
Engrave: Speed 300, power 15, 340lpi - I think this turned out pretty good.
It was a little bit of a snug fit around the button, but nothing a little sandpaper can’t take care of.
