Print failure support needed
Im attempting to print some nerf gun parts and I have had my first issues with gumming up the print head in the 5-6 years ive been printing.
I wasnt in the room when the prints failed, so im not sure what exactly the problem is.
Bolt handle file: The first attempt failed on the second layer. I came in to see strings all over and stopped it. The second attempt finished - when I came back, it had failed on layer 2 as well and there were piles of PLA strings all over.
After those 2 failures, I changed files to a 15 minute part and it worked.
BCAR file: This one I watched for 1-2 hours and it seemed fine, so I left it overnight. It printed fine until somewhere in the last hour, because when I came into the room in the morning, the print was slowly being ripped from its positoin and the print head was globbed up badly. It was still warm, so it all came off in one pull. Seems to be fine.
I think it might be the files, so hoping for some feedback there. I am printing them vertically, but maybe I need to angle them 45 degrees to the side? Also, I wanted to make them strong, so I chose 100% infill - when I did that, a menu came up asking me to change the infill pattern from the default to one that was ok with the 100% infill. Maybe thats related?
I had been printing in PETG before these, so it could be a clogged nozzle I guess, although I did have one successful PLA print before these failed after switching from PETG initially. I will use some cleaning filament and do a pull tomorrow just to check it out.
Attached the file that failed and some pictures of the failure that occurred on the long print.
