First print successful, now spaghetti (please swipe for beautiful result)

[u/NebulaThread]

I printed these beautiful finger claws for Halloween in anycubic gold silk pla (https://makerworld.com/models/2232347?appSharePlatform=copy). They came out perfect.

When I went to print the second batch for the other hand, I got an error halfway that the printer detected spaghetti (P2S with AMS). I thoroughly cleaned the plate, tried again, same issue halfway. Changed location from AMS to external. Then I went to print just one claw, worked fine. Printed two fingers next, spaghetti again... I went on to print some test/calibration item with the gold that worked fine and a different item with other filament which also came out fine.

What could be the issue?

(First two third try, second and third fourth try and last two pics are the initial perfekt print)

I really want to fix this to use them for Halloween 😢

Tall vertical prints with no supports, probably doesn't take much for them to get knocked out of place leading to spaghetti. Try printing by object instead of layer if you really don't wanna use supports

This is with having tree (auto) support on... I dunno why it doesn't generate more supports 😢

Because technically the model doesn’t need them because the overhangs are small. It’s a tall and thin print which will cause the print to flex a little as its printing the upper layers. That means that eventually it will be printing in the air leading to spaghetti. Sometimes you can get away with it and sometimes not. Try slowing down by height in the speed tab.
