Trouble with warping (feddit.dk)

I have some very consistent issues with warping when printing ASA/ABS, which is really annoying since I'm trying to print my voron parts. It's not warping massively, but enough to mess things up.

I print with these general settings, on a textured PEI flex-plate.

heated chamber @ 45-47C (can't go much higher)
bed temp @105C
first layer 255C, other layers 245C
fan off, unless it's an overhang >=50% or layer time is <10s. Fan maxes out @70% unless bridging.
speed 200/120 mm/s inner/outer walls
first layer 50mm/s, 80mm/s infill

I've tried both with my regular Z-offset which creates a good uniform first layer, and slightly lower to kind of push it more on to the plate (but worse looking)

I've cleaned the plate with pure IPA
I've tried glue stick
I've tried brim both skirts/mouse ears, which help but don't eliminate it. (5mm, 0.15mm space)

ABS seems to be a little easier to print than the ASA. I'm using filament from Polymaker

Exactly, I agree with all of the above.

Low DC voltage won't shock you, but it sure will try to burn your printer down. The lower the voltages, the higher the heat losses in critical points (with the equivalent power ofc).
