I'm getting zits or blobs in lithophanes while printing on my Ender 3 and 10S Pro. I tried a suggestion: change resolution in mesh fixes of Cura to 0.5 (from 0.05 default). That removed the zits.

But now there are white patches as shown in the image. I reduced the resolution to 0.2 but to no avail.

Anyone else encountered this problem?

Maybe it's a bad batch of filament, with dirt or uneven thickness that wouldn't be noticeable in regular printing. Have you tried a different spool or brand?

I got the answer now, it has to do with the resolution settings in the lithophane software I was using.

I had to set minimum resolution of the lithophane to 0.4 or 0.8 (I'm using a 0.4 mm nozzle).

UPDATE: sorry. The problem still persists. unable to get rid of the white patches.
