I was having similar issues.
Turn OFF the backlash setting in Mach3 first and run it again. See if it improves. If it does, then refigure the backlash.
I also had to play with the Acceleration "ramp". I could not just hit the motor at full speed all of the sudden, the acceleration starts it out slow and accelerates it at a gradual ramp until full speed is reached. It also will slow the motors down at the same rate.
