    Unanswered Y-Axis stepper motor roughness

    Solved TPU Repeatedly Fails

    I got a roll of Sainsmart TPU that is the proper diameter, and it printed beautifully at 15mm/s. I'll probably go faster next time. Now I know why...

    It did work for about two hours... and then failed again. Oh well. New filament is on the way!

    Solved TPU Repeatedly Fails

    Also I'm using my PLA oiler with the TPU now. Don't know if that's helping or not but I figured it was worth a try.

    Solved TPU Repeatedly Fails

    It makes sense that the duct might block some of the air from the 40mm fan. What 30mm fan do you use? My stock Robo fan is shot anyway.
