My son wanted his own coaster (since he saw me testing slate coasters the other day), and I tried to score a Pokemon onto .25" cork so that he could have his own coaster that would not be dropped and broken.
Even at 500 speed and 1 percent power, scoring is leaving some burn marks. I was able to engrave cork using 1000/33 settings I found in the forum with no such marks.
Also, is there a reason that scoring is limited to a slower speed?
