Here are some photos.
This print was with PVA support, right at the end there was, I imagine, a nozzle strike that was pretty deep and wound up wobbling the print until the base was actually bent and it toppled. Default Ultra Fine settings with 50% fill. No idea why this failed. The base looked solid, adhesion was good.
This print was another shot at it on Normal Settings, 20% fill, PVA support. It's hard to see but the little tiny area surrounded by PVA is where the nozzle struck and the print came loose from the bed and spaghet' was made. The base looked solid and nothing looked off.
This one was another piece of the above print. I know why this one failed. Some of the brim began to peel up but I thought it was close enough to the edge not to affect it. Nope. The print moved a bit, and then some more and then spaghetti. The XY looks off but it was whole print moving. I check the XY cal before most prints.
No nozzle strike here but have a hairy print. I'm taking a sculpting class and I bought some anatomical models to print for reference. Didn't realize there was an actual skeleton in there... pretty cool looking overall but completely unintentional. This one I changed the retraction settings unknowingly while poking around trying to solve the above.
I've printed a lot of awesome stuff too. Getting ready to start some really big 5 day prints and want to make sure I know what I am doing.
