ftn 4 warp issues

Ive been trying to print out the ftn 4 556 version and i want to print it out of pa6 but I keep getting very slight warping im using blkfde300 settings using p1s using gluestick on my bed preheating the chamber and drying the filament in a dryer before and during printing normally i just orient it to a 45° angle but the stl has the built in supports and i havent found a version that is without supports any help appreciated
