I have a few small pieces from my Predator build on the Predatorium. The wolf Predator Plasma Cannon which has nine piece and the claymore mine . I’m waiting for abs filament to arrive, Pla seems a little brittle. My issue is bed adhesion. Nerve racking . The cr-10s pro has a metal bed covered with some type of substrate , but not very good adhesion . Once i get this figured out i’ll Move to using flexible filament for the neck collar and abs for my my Mk39 build .What do you do for your adhesion issues if any ?
