Or you just stop trying ABS and print easier filament, like PETG or XT… Swapping between filaments is a no-brainer. Just new filament in and done. Prime the nozzle a bit, if it doesn’t match the color, done.
Insulate the bottom side of the heated bed, use hair spray for adhesion and make a thermal enclosure. I run ABS (prusa Air2) and except for huge parts (7" or longer) I haven’t had significant warping.
I hope you can find mods for this printer! It looks shaky in the X direction…
