The only way to know how your laser will work on your materials is to run speed/power tests.
Everything anybody else tells you will be based on their laser and their materials, which are always different from yours. You’d still want to test their settings, so you may as well fast forward to your own tests.
There may be adhesives or other contaminants on the surface. Before trying a wash I’d suggest trying a light sanding of the surface to see if that addresses the inconsistency.
thats fair. Im just looking for a starting point so i dont waste material since i haev very little of it. Tiles are very consistent, but ply is not. So even a burn test on the same ply could be misleading. one section could burn great, while another section of the same piece would not burn…
i think i need to just give up on this cheap ply i have left over from ACE hahaha.
ill try and make a burn test file. Ill start at 1200mm/min with differnt powers, then move to 1500,1700, 2000, 2500, and so forth.
