Comment on Why prime tower instead of poop?
sbeak@sopuli.xyz 2 weeks agoOops, I think I misremembered. I fixed the comment now. I typed it when I was very tired.
Now that I see your actual question, the main reason it’s a tower and not “poop” is because simply creating poop would mean the little wiper that pushes out excess filament to the poop chute needs to be used, increasing the time as there is a brief pause.
If it was poop, the printer is like “poop poop clean - wait a bit - now I print” between each layer
If it was a prime tower, the printer is like “tower tower >> actual print immediately after” between each layer

One more thing, if there is a drastic colour change (i.e. between darks and lights) then there needs to be additional stuff for the prime tower (which is why in many multi-colour prints, the prime tower has “infill” rather than being hollow)
If it was using many small bits of poop, the printer is more like “poop clean - pause - poop clean - pause - poop clean - wait a bit more - now I print” since if the poop gets too big it could damage the nozzle/clog it.
If instead it was a prime tower, the printer is like “whirr prime towerrr >> actual print immediately after”
