Loving my laser and tuning it! This issue is bugging the crap out of me what could be causing this banding? K40 cd3 mini and LW4…
Is this plywood or solid? I sometimes see this when I laser ply and the laser has burned through the face veneer layer. I always thought it could be the glue they applied to bond the layers.
I just started to think it was the glue rollers I will back off on my power
yes its birch plywood from a box store
You could check if it’s the wood by rotating the material by 90°
Sure looks like the banding follows the grain, matching up with the grain outside the engraved area.
Vibration can also cause banding like this. See this old post of mine.
