So, today I printed a 3.25 hour print. it took me three failed attempts using a brim (the brim kept coming off the bed) on my glass bed. I tried to raise the temperature to 65, then to 70. Still no luck.

Then, I saw a video that taught me that PLA doesn't need a heated bed, so I set Cura to 0 degree bed temp. I used a glue stick on my glass bed and started again. The print was perfect. The bottom looks amazing and it stayed on the bed for the entire print.

I've finally found something that works for me. Now to finish that 13.5 hour print...
