Need advice what I should adjust to get clean print
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?
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.
Thank you very much for your fast replies. I'll try your suggestions and come back later.
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.
