Printer : Kobra 2 neo
Excessive retraction can even show as uneven layers. But in this case, its strange how seam is oriented, so maybe wet filament? OP didnt post details
I think this picture might shown at least two différent issues
I had them on my printer and was because of retractions, if they are not good enough the blob can do this on the whole layer, at least on my experience. Lowering temps a bit helped me
Looks like you have random layer seam location and too much retract on layer change
I think this too. Not sure why you're getting downvoted.
How old is the filament and has it been properly sealed?
Check the temp too
I would say load up the model like you had it in your slicer and look at the preview. If the start/stop points of the outer wall line up with those voids, then it's a retraction issue.
If they do NOT line up with those points, try a different roll of filament as these could be artifacts from moisture in your filament and popping during extrusion.
Those are seams.
Agree, thinking seam set to random or whatever. I would make sure set to align, or paint the seam where ya want it.
Agreed, but weird that they're a void. Usually it's a bump.
There's a setting in Orca called called seam gap. If you run it too high it will leave a gap instead of a bump. Theres a theoretical middle ground that leaves it completely smooth but I've yet to find it lol.
Have you tried the new "scarf joint" seam?
It's supposed to be great. I'll use it here before too long.
I'm just getting accustomed to OrcaSlicer. So far just used it for calibrating prints.
I haven't yet. I need to read up on what they are before I use them. It's got a couple different options something like curve and curve and hole. I have no idea what those means but I generally like to have at least a vague understanding of a feature before I try it out.
Scarf joints actually come from woodworking.
Essentially the ends come together in two 45° (or greater in wood) angles instead of two 90s.
Someone figured out how to do this in FDM printing and that it greatly diminished the appearance of the seam.
See I knew I'd heard that term before. I watch a few real woodworkers online and I can make some stuff but I'm nowhere close to anything impressive. I know some basic joints and that's all I've really tried. I bet someone I've watched on YouTube made something with them.
They're often used to join stock together to make longer stock. It makes for a stronger glue joint than a butt joint.
That would make sense. More surface area contact from both sides.
i have the same prob
Small « dots void » may be too much rétractation
