Ninja SemiFlex

Hi All,

I am not sure if I am having issues printing semi flex, or if my expectations are not achievable.

I've been trying to print with ninja semiflex (which I understand is easier to print than standard ninja flex). I've gotten okay results by lowering print speed to 10mm/s, 1.25 extrusion multiplier, 235 Deg C and did the standard tube support to stop the material buckling (previously I was having extrusion issues).



I've also tried combinations of cooler (210 Deg C) all the way up to hotter temps (250 Deg C), it seems to be around the 230-235 mark I am getting the nicest prints. Any lower and I have issues extruding.

I've also tried some faster speeds up to 20mm/s, as I read one person had some success there, but it seemed to have also failed for me.

Some previous failures (and some fairly successful prints):


So in the first image above, is that about the best qaulity between the layers that I can acheive? It just seems a bit to rough from what I've seen from standard Ninja flex. I can't seem to find many examples of semi flex prints out there to compare too.
