hi , im retrofitting a machine with mach 3, pmdx 126 breakout board and panasonic servo drives and motors, i have movement on axis now , but always in same direction , mach3 displays show correct movement but axis goes in same direction, i can change motor output pin numbers and direction changes but still goes in only 1 direction same if i change parameter on drive , direction of movement changes but goes same direction whether jogged in + or - direction.

thanks
robert brintle
