  I’d be surprised if it was too cold, but I’ve heard stranger. This is PETG at 250. I’ve actually pulled the nozzle and Bowden tube and pushed a very small Allen key through, so it shouldn’t be clogged.

  Z height is calibrated, and I’ve calibrated the e-steps for the z axis. I’ve tried disabling the fade height to see if that was doing something but it didn’t seem to make a difference.

  I ran through calibrating the extrusion e-steps. It’s feeding 100mm when I tell it to do so. I haven’t messed with the extrusion multiplier, do you have any information about that?

    250 for PETG

    This is quite toasty, at least for the PETG I print. I’m usually at around 240 for my first layer and 230 or 235 for all subsequent layers.

    Have you run a temp tower?

    I haven’t messed with the extrusion multiplier, do you have any information about that?

    ellis3dp.com/…/extrusion_multiplier.html for more info. In a nutshell, you lower it for oozie filament and increase it for more viscous filament. For PETG I lower it some, but the exact amount varies by filament brand and color.

    That said, I don’t think this is your issue.

      I haven’t run a temp tower. I’m not fully convinced that it won’t damage itself so I’ve been trying to think through it before trying another print.
