Bigfoot Halloween Round Slate Plaque Coaster with Trick or Treat Motif

This slate coaster engraving was done on the F2 Ultra UV.  Prior to engraving I lightly sanded to smooth the slate, then applied a Clear Acrylic Sealer.  The PNG file was loaded to Xtool Studio and I selected the machine type and rock coaster.  Then auto adjusted the file.  This did invert the file.  The Xtool settings were used for the engraving – dot duration--280, power 95%, DPI 500, and Freq 40.  When complete be sure to rinse the slate off with water to clean off the dust.
