These are the parameters to use when cutting various materials with my K40 laser. They have been discovered by trial and error.
Note: This stuff is very likely to start burning in the process. These values are not yet ideal, we might want to try going with lower power/speed and do two passes, which would be easier on the wood.
bought from here, very fragile
Note: This will leave some heavy soot on the material, it’s not exactly a clean cut.
