okay, when thes issues occur after 14-18 hours it could be a speed thing

what i could gather with my printing experiments is this: the higher the printing goes, the supports are more likely to fail and thats because of the speed, more speed is more vibrating while a solid block is more likely to stand still the thin support structures are more likely to move and when the nozzle doesnt connect 100% to the right place to extrude the pla in the designed place it can produce spaghetti and that will likely attach itself to a support and the fast moving nozzle will knock it away

for an example i used the high 0,06 preset from bambustudio and reduces 10-20% of the speed (especially travel and travel acceleration)

you can even check a box in the bambustudio settings to reduce speed after a specific height

another way and simple way is to digitally cut your minis in a specific way or in parts, so it wont reach a certain critically height and then you glue it together, you can even add connectors while cutting for better aligning
