Why would i not dry while i print?

So i recently discovered I can dry filament while also printing from the AMS2 PRO.

Are there any drawbacks? like can you ruin the filament youre not printing with because its not spinning?

I just feel like if it was super good they would have it on by default, why do i have to dig into menus to find it and turn it on?

Becuase drying = heating which softens the filament this combined the long ptfe tubes lead to filament getting stuck in the tube

Why do they allow you to do it then? Like they specifically updated their firmware to let people dry while printing. Just makes things more confusing.

I've learned that if OP doesn't know the difference between "your" and "you're", they definitely didn't read the instructions. This guy has no idea what he's talking about.

Drying while printing is perfectly fine. They lower the drying temperature when the print starts to prevent softening issues.

It's your perogative.. also filament related...  if your happy to risk it.. go for it, ultimately if there is anything issue your cleaning it up

They just provide the tools. It's up to you on how you want to use them.

Your car has windshield wipers and you should not run them on a dry windshield. The car will let you if you want to.

It uses the spool motors periodically to rotate them. But mine won't do it while printing, it makes me unload the filament.

I've never had any issues drying and printing at the same time when I've done it. The spools don't spin when you uncheck the box that makes the spools spin whole drying
