Bends From Corner

The model sits perfectly to bed at the begining but than it bends from corner. Base heat is 0 or 60 degree doesnt matter it happens. i use bltouch,  glass as bed, as stick i use hair spray

It is normal warping and can be solved with a good/better bed adhesion.

Try glue stick or something else, not every hair spray is useful for 3D printing. Another reason could be that the distance nozzle - bed is too big. Try to level a little bit closer to the bed.

 

Post a picture from the bottom of you object, then we can see more.

Bed leveling looks good, so I think that's not the reason.

 

clean your glass and apply some glue stick and distribute it with a wet tissue to get a thin layer of glue.
