How can i get a large print to stick???

Buildtak works well for ABS... perhaps too well.

You should try it before abandoning ABS.

Okay...lets establish some photo proof. Something doesn't seem right. BuildTak is essentially the best adhesive you can get.

Please post pictures of your print when using BuildTak. If you are using BuildTak with a 100C build plate, and a properly calibrated Z0 gap (paper test) then you are going to have to use a putty knife to remove the print. Even if the edges curl.

Also, "Not Sticking" is different from "Edges Curling".

Have you tried using a Brim? You can brim the bottom later which will significantly improve edge adhesion at the part.
