In this paper, we investigate the space of certain weak stability conditions on the triangulated category of D0-D2-D6 bound
states on a smooth projective Calabi-Yau 3-fold. In the case of a quintic 3-fold, the resulting space is interpreted as a universal covering
space of an infinitesimal neighborhood of the conifold point in the stringy K¨ahler moduli space. We then associate the DT type invariants counting semistable objects, which give new curve counting invariants on Calabi-Yau 3-folds. We also investigate the
wall-crossing formula of our invariants and their interplay with the Seidel-Thomas twist.
