I have a random dot problem. I came across this thread but there is no resolution! Dots appear all around engraving
Everything was going great and then my laser died. I wasn’t sure if it was the laser or the PS so I replaced both from light object. I bought a 45w SPT tube and a LO branded power supply. Everything else is exactly the same. I see it when engraving leather. For the most part you can’t see it in the final product after some oil or dye. But it is there and driving me nuts. It is outside the scan area too. Basically anywhere the laser head travels. No issue when cutting. Optics are aligned pretty darn good.
I did 3 test engraves. First one was 10% power which is where I like to engrave patches. Middle was 25% power. Bottom is 14% power. Air assist off for all engrave and on for the cut.
I would think that the dots would be worse on the higher power but they basically are absent.
