I have some cork left over from a building project. 12" x 12" squares .2174 thick. It was used for covering a wall.
Seems just perfect for a coaster.
It engraves fine with Speed 1000 and power 12.
I can not seem to cut it. I have tryed:
150 /100 makes a campfire but still does not cut it
500 / 30 make a nice clean score but only 1/10 inch deep
tried focusing down in the material some after the first cut . huge burn marks and LOTS of smoke
Several other tries.
Thinking of doing a bunch of concentric circle vectors to cut down a ways then repeating ata lower level ut there seems like that is a better way that I am missing.
Or maybe this just will not work !
