I'm using the Gamma X-2 machine to string my Pure Drive GT. I'm doing two-piece stringing and skipped mains 8T and 8H. However, after i finished stringing the mains, the string bed looked a little off. I counted 16 main strings. I quadruple checked to make sure i skipped 8H and 8T. 6H and 7H look a little off on one side of the stringbed. Also, I am not able to string 19 crosses... the holes don't match up. What could I be doing wrong? I also find it very hard to insert the string into the grommet where i am supposed to do a starting knot. It seems that the main string is blocking the entrance. Is this normal?
