Unable to finish prints successfully
Hello. I posted earlier about some stringing issues I was noticing on my prints. I attempted a few new prints, and each one fails roughly halfway through with what looks to be spaghetti monsters and blobbing. I took the previous advice and dried my PLA filament in a dehydrator for 6 hours at 45C, but the issue still persists.I also slowed the print speed to ~80% to see if that would make any difference, but as you can see in the photos below it did not. Different print models did not make any difference either. It's strange because the prints appear to start perfectly, but then fall off the rails later on. Any advice on what could be going wrong would be greatly appreciated because this issue is stopping me from completing any prints.
PLA Filament: 210C
Bed Temp: 60C
Prints are not being pulled off bed so it appears that they're sticking properly.
RE:
Please show us your nozzle/hotend assembly from two different angles.
The bottom of a failed print might be informative as well.
Cheerio,

Looks like poor extrusion. I agree with Diem. Odds are the answer will be revealed with a photo of your assembly.

Thanks for replying. Attached is a photo of the bottom of the failed print along with some photos of the nozzle/hotend assembly. If you need a photo from another
angle let me know and I'll provide it promptly. I did an initial scrubbing after it blobbed up, but if it needs more cleaning I'll do that again.

IS the thin section protruding from the side a layer shift or not ? If its not and its supposed to be protruding then where is the support structure that should be under there ? You have enabled supports havent you ?
Please save your project from Prusa Slicer (File>Save Project As) then take the resulting .3mf file and ZIP it up. Once zipped use the attach file button to add it to a post here. Must be zipped or the forum wont accept the file.
With a project file we can slice it with the same settings as you are using as the project contains all that extra information. Its the best way to debug slicing issues. We can at least rule out software related things allowing us to concentrate on potential hardware problems.

Attached is the zip file for the print that failed.
Thank you, there is one thing you can check that isn't clear from the pictures; the second hotend picture shows solidified filament very close to the top of the heat block - is there filament oozing out of the threads at the top of the block?
Your .3mf doesn't have supports enabled; this part will fail without support.
And you are using 0.05mm ultradetail which is entirely unnecessary here, I would use 0.2mm layers.
A minor problem that will appear later; those curved edges against the build plate will not print cleanly, if this is your file I suggest chamfering at 45degrees to soften the edge whilst printing neatly.
Cheerio,

Looks like Diem has it covered already. I thought it looked like there was no support. You cant print in mid air.
I'd make the changes to the model suggested if you can but if not then try the attached project.

Thanks a bunch! I'll give these adjustments a shot, and see how it goes
