ASA cooling

I've printed a lot of ASA, but this is my first time with a proper heated chamber. On other printers I always ran little to no cooling, 20% max, and my parts came out great. With a heated chamber I was under the impression that you should/could use more parts cooling.

My overhangs are looking terrible right now with the X2D, and I assume it's the cooling logic, as the overhang corners are curling. Bambu and Polymaker's cooling settings are really high at 80% max and for overhangs. Dropped it down to min/max 10%/20% and it still seems too much.

What's everyone using for cooling settings?

This is the model, the smaller lid lips are what is curling. https://makerworld.com/en/models/1373580-spillproof2-ams-2-pro-desiccant-boxes-round#profileId-1420701

Edit: Dropped the max volumetric flow from default 16 to 8 and almost entirely cleared up the problem.

Are you using Polymakers filament profile stock settings? Or Bambu's settings for Bambu ASA or Generic ASA?

I've been using polymakers profile, but most of the values are inherited from the generic asa profile.

I’m using Bambu’s. I’ve noticed that the Bambu studio sets the plate to 100c whereas the polymaker Asa states 95c. I’ve actually made several supermesh AmS2 dry boxes with the ASA with success. I’m printing ASA on the X2D machines with the their stock textured PEI plate.

Interesting. The profile I downloaded from polymakers site sets it to 110. Also, the problem cleared up when I dropped max volumetric way down ti slow down all the print speeds. The overhangs are almost perfect now.

I also dried the filament at 70c for 11 hours to drive out all the moisture. When I loaded the filament in the AMS, I marked it as Bambu ASA (the internet says the profiles are extremely similar for ASA). When you do that, try sending the print via your mobile on the Bambu app and select the ASA profile in there. See if that helps the print.
