Brims, glass, hairspray, first layer speed all help.. The best in my opinion is to make an acetone slurry up and give the bed two coats, in opposing directions.. ;-) 8inch x 5inch print last night... , No brim/raft --->Zero warp...a brush of acetone on a brim helps hold the corners of the brim down if u want to use the brim route...but really I can't see past the slurry for those prints u can't have any warping on.. My 2p!

a light coating of hairspray, and setting the brim to 4mm, and setting first layer speed to 60%
After I did these things I never had another warped print. The hairspray lasts for a long time and you really only need to clean it off when it becomes too thick to be level.

+1 on all this. I run my 1st layer speed at 50% On large prints that are a 100mm or more, I set my 1st layer extrusion width to 200% and run a 6mm brim. On prints between 50mm-100mm i'll use a brim of 4mm. Anything less than that, 1st layer width to 150% and no brim.

I'm using the stock SD3 bed with Kapton and hairspray. I have found that my large prints stick so well that I have to heat cycle the bed to get them to release.

I also have been running the 1st layer temp about 5° hotter than the rest of the print. I have to run my black filament hotter than my red, so it seems that filament temps can vary.

Happy printing

Get a piece of glass, use hairspray, heat your bed to 100C (and make sure it reaches that temp before starting) and use a brim.

It will help but you will still run into the occasional lifting. You may also want to experiment with a raft.
