Need advice what I should adjust to get clean print

Hi,

I printed this Voronoi ball with my MK3S at 0.15mm quality. Different materials (FLEX and TPU) show the same results. During the print I changed the print speed to 80% and later to 120% but that did not change the print.

Which settings should I try to get a clean print?

Try increasing your retraction.

There is not much you can do. Any flexible material generates strings. I'm glad you were at least able to print such a thing in flexible material 🙂

Increasing the retraction (or better set higher K-value in linear advance) might work but you're also increasing the risk of failed print.

Begin with a temp tower.

Begin with printing a string test model.

I would also say that a temptower is the best way to estimate and influence what is happening. With every new filament I perform a "temptowercheck". Usually there is always something to optimize.

Temp Tower did not really help. The best temp in PLA was 190°. The ball still looks the same.

Will check the other suggestions

What is the exact material you are printing with? I find that when printing with a set material like fiberflex or Ninjatek I followed what the manufacturer has on the package and slowed it down even more. I also replaced my bowden tubes to keep the filament from binding on the retraction if you dont have a mmu2s.
