Large multi-day print warping (Printing with Polycarbonate)
Hello, I have a few questions about printing things with Polycarbonate.
I recently started printing a large mount for a speaker, and I decided to print it out of Polycarbonate. I don't have that much experience printing with Polycarbonate, I just picked up a spool, did a few test prints, and started the mount and put the PC in a drybox while printing. It is a 3-and-a-half-day print, and about 1 day and 18 hours in, I checked the print, and it was warping a lot (see pictures). This was weird, as I checked the print the same morning, and it looked fine. 7 hours later however, the whole front of the print started to warp 2-4mm off the print bed. It's not the end of the world, as the print could probably still be used, but I need to print more mounts so I kind of want to figure this out.
I know that PC has a tendency to warp, which is why I used the enclosure, but it still warped. Could it be that the front door is not sealed enough, and drafts are getting through? Or that the chamber cooled down too fast? (The chamber was at 38°C when I started the print, and when I checked it, it was at 35°C) I would love some help, as I love PC and I want to print a lot more parts with it in the future.
