I have an enclosed P1P equiped with AUX fan and MC board fan. I‘m thinking about drying filament with this like the X1 it does. But I assume the X1 has a menu option for this and use a special task for this. My question is, what the X1 is doing while drying?
At the moment I try it using the heatbed heated to 90 degree and placing the filament spool on it.
I was thinking to do the same but unsure what bed temp to set. How was going?
I think, I read somewhere, that the X1 in his drying function set the bed temperature to 100°C and so the enclosure heats up to around 40°C. The timer is set to 8 hours? Can this be confirmed by a X1?
The drying function on an X1 is super-slow and less than effective, in my opinion. It exists simply on paper, as a nice feature on a list of features that nobody really uses, I don’t think.
You’re better off with a Sunlu box. The temp goes higher. It’s a faster, more consistent result, and it uses less power to do a better job.
Also there are some food dehydrators out there for bargain prices, which do a fantastic job. It depends on where you live as to which locally available device is the most cost-effective, but that’s what reddit is for. Reddit knows food dehydrators for filament drying.
I know spending extra money might not seem appealing, but believe me, 16 hours with your bed temp on 100c and your printer being unable to do anything else in that time, is also unappealing. Especially when the result is almost as if you hadn’t done it at all.
Yes I know. It was only a test with a filament, because I don’t have such a dryer at the moment. But it’s planend to buy. You named the reasons. 
Did your spool make it? I’m assume 90C bed was too much for both the filament and spool if you were drying PLA.
I think its a good idea as a stop gap, but I would definitely use a filament box and something to get the spool directly off the bed. That way you trap heat in the box, but insulate the spool and filament from the 90C bed.
It was only a test to see how much temperature I can get in the enclosure. I‘ve got around 30 degree celsius. And yes, the spool survived.
For details I found the wiki entry for drying filament: Procedure and 3mf file for drying filament with the X1C heatbed | Bambu Lab Wiki
But anyway, it‘s better to use a dryer instead of blocking the printer 12 hours with filament drying. 
Its a stop gap, the $60-70 special dryer will almost always be better. But as far as taking up my printer, that wouldn’t bother me. I’m not running a print farm. I don’t need, or want my printer running at all times.
That said, I did buy a dryer and never have to worry about it. It would have been nice to use the printer as a test for whether it was worth buying. Free testing is always better than equal paid testing.
ya you can, I made my enclosure from ABS, PC and acrylic for the doors windows plus added seals to any cracks so it can get really hot, when printing with PC the inside of the enclosure gets over 100c, hovers around 95c, to 105c so sometime I put a spool at the bottom to begin warming up and drying if i have both my other filament dryers full already
For my limited needs, drying in the X1C gets the job done. I only print a couple times a week, don’t have or need an AMS. I’ve been using an old filament box with the lid cut off as a cover. I do need to plan ahead for prints with TPU and PC because adding 12 hours of drying before starting a print tends to conflict with sleep and life.
I don’t have way to reliably measure humidity or moisture content, so I’ve been using a digital scale to weigh my spools as they come out of the box, after drying, before going back into the storage bag, and before the next use. New 1 kg spools often lose 4 to 8 grams after the first drying, which can be the difference between unusable filament and a very good print. If a partial spool gains more than 2 grams in storage (and they can, even in a vacuum bag with desiccant), it is dried again until it gets down to the previous weight.
