Hi, I've tried to print a model plane for my father. It's this model, using this LW-PLA right after purchase.
As you can see in the image of this post, the print is going well until it reaches a certain layer, where the filament does not get deposited properly for the entire layer, only intermittently. The following layers then, of course, have the same problem and I get this failed print with these "frayed ends". Additional attempts failed the same way at a similar layer count.
If someone has some experience with lightweight PLA (LW-PLA) and knows what can be done to solve this, I and my father would greatly appreciate the help.
Thanks in advance.
Edit: Additional info: I'm using the PrusaSlicer files from the linked page. Edit2: The printer is Prusa Mk4.
This looks like a clog caused by retraction.
Is it clogged when it finishes? Also, does the cooling change at this layer? Is there anything specific to this layer?
I assume, a clog would be obvious to notice? I don't think it was clogged. I did multiple attempts back to back and it started the next attempt without problem at layer 1. As someone, who is rather an amateur, I don't see anything special about this layer.
not sure, but looks like vase mode, where there shouldn't be any retraction.
It's not vase mode, but the model creator designed it to print layers without retraction. It only does a retraction to start the next layer.
