Any Suggestions on getting the prints to stick well to the kapton? I am Using Octave White with 195C on the extruder and 95C on the bed. The bed is level and the Z offset is just right, But about a quarter the way into a print one corner will begin to peel up and I kill the print. Any Suggestions?

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

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