Z will not go Up

Ok I am no stranger to Marlin and how it works.... there is no lines for fixing this Issue 2 things the Z tends to Jam and it will only go Down... Early versions of Marlin had a way to correct this issue but I cant find it in Marlin 1.1.9...and it cant be that hardware I had it running on my Hypercube some weeks back think its the same issue as always 2 motors one Driver.. getting half of everything...nope even with weak settings it should turn the M8 Rod OK...

motor direction this is v2.0.x bugfix, but I think it is similar in 1.1.9

// Invert the stepper direction. Change (or reverse the motor connector) if an axis goes the wrong way.
#define INVERT_X_DIR false
#define INVERT_Y_DIR false //11
#define INVERT_Z_DIR true //11

Y & Z are not default, they are my changes.
