Interested in the same thing. I just started printing PC, and while the prints have been turning out amazing, I'm wondering if we can keep the chamber temperature up as the PC material requests.
- 7 months later...
Recent firmware upgrades appear to have changed the air manager behavior. It will now report out the chamber temperature through the REST API and while I don't have any official confirmation, it appears they may have finally implemented closed loop chamber temperature control. 45C is about the highest chamber temperature I've been able to reliably maintain, without changing the hardware. With a supplemental heater, I've gone as high as 60C, but even at that point, things get challenging for the motors and the hotend fan (the one that cools the heat breaks). Heat creep became a very real problem at that temp and I was not able to get very good results. I've done better using 50C chamber temp settings (which again, produces more like 45C) and a draft shield to keep the heat around the model. I stopped using the UM PC though, since I couldn't get it to work with soluble support of any kind and the supplied profile was not very good anyway. I've had great luck with Polymax PC, along with AquaSys120 soluble support when needed.
Also, can anyone confirm if the Air Manager actually does close loop chamber temperature control? As near as I can tell, it just picks a fan speed at the beginning of the print and keeps it the same, regardless of what the chamber temperature actually does. @SandervG ?
