If you have a printer that has these features, try it out and see the differences for yourself. There’s probably a reason why it’s set up the way it is, but sometimes the differences are so minute that you don’t notice or care. If you run a few prints and the color swaps look like garbage, you’ll have a better understanding of why the printer and firmware are set up that way. If it turns out fine, congratulations, you’ve made a personal improvement to your machine!
Comment on Why prime tower instead of poop?
Blue_Morpho@lemmy.world 1 month agoThe purge area always has a wiper. I don’t see why you can’t prime into the purge chute - wipe, then move to plate.

I’d rather understand why than have a print randomly fail in the future. That is just because one model can print without a prime tower doesn’t mean all will work under all conditions.
I’d love to get a real answer.

That’s why I suggested testing it and seeing the results for yourself, not necessarily “turn it off and yolo”.
If you know firsthand what the outcome of changing the settings is, you can make a decision on your own based on your own experience when to use what settings.

Testing on a print means nothing. Just because one print works doesn’t mean it will work on every print. If I understood exactly why there is a prime tower instead of purging for prime I’d know under what conditions it could be disabled.
Maybe it’s a historical artifact from printers from 10 years ago. Maybe “build nozzle pressure” doesn’t work as well if you aren’t priming onto a surface that would create back pressure.

Because of gravity and time.

It’s not like the slicer adjusts the prime tower to be close to the objects. In fact it does the opposite: It places the prime tower in the far corner.
From googling it seems like if you turn off the prime tower, it primes into the purge area. This means there’s no point to the prime tower except for printers that can’t purge.

Well, turn it off and see how the quality goes.

Purging into the chute doesn’t leave the nozzle with the same pressure as priming onto a surface because there’s no resistance. So even if you retract the same after both, you’ll get a different line start. Priming onto a surface is the best way to guarantee that the next line start is identical to one that comes after a print move and not differently due to coming from the poop chute.
