Hi everyone. I’m having some serious issues printing with ninjaflex. I’m not new to this filament, and have successfully printed quite a bit with it, but recently I’ve had consistent failures with some files I’ve been working with. They’re meant to be prints of leg muscles and I’ve tested them all in meshmixer to assure they’re okay for printing.
I’m printing on a TAZ6 / Flexystruder v2 using legacy Cura, and the default ninjaflex profile.
I’ve successfully printed both of the files I’m trying to print before, but I didn’t note down the settings I used. (Though I don’t think I changed anything from the default Cura ninjaflex profile.) I managed to get something like this:
Now I’m consistently getting this as a result:
I get a few okay lines but the printer just seems to give up partway through and everything gets fuzzy.
I’ve tried both the default Cura settings and these tweaked settings, based on research I did, both with unsuccessful results:
Layer height 0.3 (I’ve also tried 0.2)
Retraction: On, 1.5 (I’ve also tried turning retraction off)
Print Speed: 14
Print Temp: 220
Bed Temp: 40 (w/gluestick)
Supports: Everywhere, Lines, 17% (I’ve also tried denser support infill)
I’ve also tried the flow rate at 100 and 145.
I’m not sure what I’m doing wrong. It seems to be something with the supports. I printed out a small, completely flat test file using the same roll and settings, and it came out perfectly. I’ve also tried switching out rolls and am having the same trouble.
These are how the supports looked on the other successful print, but I cannot get these to replicate.
Does anyone have any advice for what might be happening here?
