I have an Epilog Helix 40w that when using the vector grid and cutting, I get burnt hexagons from the grid on the part. It looks like it might be vaporizing something in the grid but I'm not sure. This just started recently and I'm not sure if it means I need to clean out my grid better or the settings are off. Is this flashback?
I did just clean the grid last week with Super Clean and an older synthetic brush but I think need to get some big, fuzzy pipe cleaners to scrub out the honeycomb so it doesn't take 2 hours to clean.
I tested on a tongue depressor, but I'm getting that mark as well on laser-able finished Alder and it's marring the finish in the exact same shape...
