Has anyone had success with the Cermark LMC 6044 on ceramic tile purchased at local home stores? I have been running tests and the closest I get to making it work is 8 speed and 10 power on my Epilog 45 watt machine. Laserbits tech sheet says to use 100 power and 70% of your machines wattage for the speed. That just blows thru the outer coating of the tile. I have used 3score's laser tile and it works wonderful at 100s/90p. just cannot seem to get the right combination on the Cermark.
