Banding black lines

Hi everyone. I use a creality falcon2 12w from a couple of months, and never a problem (at least heavy problem). From few days i saw a bending problem on engraved image, so I checked out all the mechanical part, tightened all the belt and eccentric nuts,tryed different dpi and lpi, different material, but nothing.


I’m not seeing the bending or, more literally, I assume banding issue you’re referring.

Can you edit one of those and circle it. Might want to add items like what material and maybe the process you’re using…

Once I zoomed in, I can see it. What interval are you using and I assume these are porcelain tile?

:smiley_cat:

Yeah the first one is ceramic tile, second one is laser paper. It 423 for tiles, 254 for laser paper.
Edit new. I made rectangle test, modifying x axis band tightening for every rectangle, and I find out it was the problem. This one is on laser paper 318 dpi
