I believe this was caused by the horrendous layer adhesion of this silk PLA. Didn't have time to tune the filament, and based it off of another silk one.

Too bad this print is a lot of discards...
Few years ago I had similar issues with silk PLA - until I accidentally sliced it with a prusa PETG profile. Came out absolutely perfect. Since then I just treat silk PLA like prusa PETG.
I'll give that a try!
What printer do you use, is it a predefined profile?
Yeah, Prusa Mini and (back then) mk3s with PrusaSlicer
I really don't get enough macro plastics in my diet. That looks delicious.
@anguo Actually it seems like your bed slipped halfway (see the sudden misalignment on Y axis clearly visible on the bowl) and even though printer kept printing well afterwards, it propably reached some point where it started printing "into the air"
Everything that was supposed to be attached at the bottom of the bowl, wasn't. There were three poles and some sort of tower, all with small footprints. All the supports weren't attached either. I also could easily separate the layers with minimal force.
I think you're right that a bed slip caused a chain reaction, but the layer adhesion certainly didn't help.
I also could easily separate the layers with minimal force.
I consider this information important as this mean it's not sticking for some (not hot enough or not enough material?) reason.
I only had splittable (not that easily though) layers with ABS/ASA, never with PLA or PETG
I just retightened the belt and lubricated the rods a week or two ago, after another failure, not sure what could have caused the slip
Already in a bowl. How convenient
Crazy to me that printers still aren't a bit better at detecting this.
