You can print ninjaflex on your printer. It requires a quick mod to your extruder (takes a couple of minutes) and you're set. I described the mod some here on the boards, can't find it right now but search shouldn't be too hard.

PTFE begins to degrade to 260 degrees. Depending on the grade you have its anywhere from 260 -290 actually. People state 240 degrees as a safe zone. Beyond 260 and you will after time have to replace your PTFE tube and definitely work in a ventilated space as the fumes can cause flu like symptoms in humans. I print Ninjaflex at 240ish on an FFCX and it works fine.

I don't know what you are printing. Upload a photo?
