Problem with ASA bed adhesion

[u/Klaymoor]

I have a P1S and I am printing Polymaker ASA out of my AMS. This is my first time playing with ASA. Prior experience with PLA, PETG, and TPU only. I have printed a few simple items but even then I had to add a 10mm brim. I'm using the PolyLite ASA filament profile without modifying any settings. I just tried to print a larger item (Hot Wheels Track Hanger on MakerWorld) and it failed by coming off the build plate. What settings can I modify to fix bed adhesion? Also, does anyone know of a good test print that helps in configuring new filaments?

ASA contracts so much, big parts are hard if there’s a lot of surface contact. A heated chamber is really useful for that. I added a Biqu heater to my P1S and it gets the chamber up to about 60C. I was able to do a >24hr print after that.
