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.
I’d think it’s the overhangs as well. Try reducing layer height or increasing extrusion width. The ratio of those determines the max overhang angle.
Yeah, looking at the suggested print settings for vase mode makes me think I’ll need to mess with the temp and speed. I kept them mostly the same as my non vase mode profile which is probably is the issue.
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?
I didn’t do anything different slicer-wise, but I resliced the file with a higher temp and that seemed to solve the issue.
Then I checked the x gantry and found a ~2mm variance so I had to do that for the first time and now everything seems to be running great now lol.
Nice catch. I thought it was probably mechanical.
Looking at previous runs it seems that the imperfections are there as well, but more minimized:
