The grinding noise is (usually) when the motor reaches its torque limit... Double check the extruder assembly moves freely along the entire X Axis, and that the belt tension does not change over the travel (and is not excessively tight). Check the motor is not over heating, it should only be warm to touch. If the motor is too hot to touch its possible you have your pots trimmed to high. As a bench mark you can trim down as low as 250 mV, although to avoid skipping I would suggest 350~400 mV as a baseline....
