Aaron, Micro stepping works better at slow speeds. In my Gecko 203v drive it morphs from 10 microsteps to none as the rpm goes up. I'm guessing your just trying to go to fast for your hardware. If a G0 move goes bad then your max velocity is set to high. If you lose steps or stall the motor on direction reversal then your acceleration is too high for your hardware setup. Slow it down until you find the limits for G0 moves.
Your not cutting at max speed I assume so your down within the range of your hardware at your speed you set for cutting.
