ahh this is bummer news. Ive had a FF dreamer for a little over a month.. Ive been pretty happy with the results overall, its my first printer. And although it has a "looks like its made cheap" quality to it. Ive been over all happy with PLA and ABS prints. I actually prefer abs.. just looks nicer imo.. But I digress.. I wanted to try some ninja flex and bought a spool and as you can guess could not get it to work. come to find out its my spring loaded feeders.. gah.. I shant give up!! 8)
