Hello everyone, I am a complete noob to 3D printing. Just got this machine and have successfully printed out quite a few parts for a RC airplane out of PLA. BUT, I tried today printing TPU for the wheels on the airplane, and am having an extremely difficult time. TPU is dry, just opened it out of the box and put it straight on for the print, settings for the print were as follows: 230 print temp, 40 degree bed temp, no part cooling, and no retraction. The first few failed prints I was getting a little coming out of the nozzle but it would just blob up on the nozzle instead of sticking to the bed, and now I can't get anything to even come out. Not sure where to go from here? Help please!
