TPU issues, sorry if its been asked before!
Hi all,
So I am not new to 3d printing, but TPU, that is another matter!
The items that my business print off have some TPU parts. And they where all printing ok when I had the MK3.9s's but I have upgraded all to MK4S. And this is now a problem, I have converted (stupidly) the files to MK4s and now the quality is absolutely dire! Far more flexible than it was on the MK3.9s's, there is so much stringing, I will let the pictures I have attached speak for me, it will be pretty obvious which is which.
I have dried the filament for 12 hours in a SUNLU drier, humidity was down to 12%
Any ideas, anyone got an example TPU profile they would be willing to share??? HELP!!!!!!
I have tried with Ninjatek TPU (which is what I have been using), I even bought some ERYONE TPU to try, and got the same results!
