Hey all, I just finished a run of Popandsicle’s excellent vase mode ornaments and I noticed these weird bulges happening all over the prints. The last run in a different color was flawless so I’m not sure where to start. I couldn’t find much on the issue with a bit of googling so I thought I’d check with you folks and see if you all had any insight.

I’ve calibrated my esteps and adjusted the resolution to be a bit easier on my printer (modified CR-10v2), and unfortunately my mainboard isn’t capable of linear advance.

Filament is overture royal gold, layer width is 0.6, height is 0.2.

I appreciate the help!

    It looks like it’s happening at about the area of steepest overhang and while going around a corner. Is it possible the bead of filament is not grabbing onto the previous layer and dragging/sagging?

    Maybe try slowing down the print speed a bit and/or increasing fan speed.

      It’s definitely sagging, this happened as I was composing the OP:

      That’s the worst I’ve seen, usually it’s like the original picture… Oh damn I just noticed it happens at the same layer heights every time.

      Hmmm, so why would this filament give me trouble and not the other one? Or is this a z-axis issue or a slicer one?

        I second callcc’s suggestions. I don’t think it’s a slicer or hardware issue, just optimizing your print parameters for the filament.

    This is consistent across runs in the exact same spots.

    I think it’s either mechanical on your y axis hardware or you’ve got a corrupted slicer file somehow. are you converting these differently than other prints in the past?
