It's great that you solved your issue, but could you [edit] and expand upon your answer a little? Are you referring to the z-axis stepper driver? If so, turning in which direction?

<p>I have an HBot 3D 1.1 printer (it's a CoreXY style printer)  which I use together with Cura. I print in PLA at  200 °C. The print bed is set to 70 °C. I use a print cooling fan at 100 %. The layer height I set to 0.2 mm, the line width is set to 0.4 mm from the 0.4 mm nozzle. The Printing Speed is set to 30 mm/s for walls and 60 mm/s for infill. My retraction is 6.5 mm off at  25 mm/s.</p>
<p>Two other settings I've adjusted are print jerk (from 20 to 1 mm/s) and acceleration (from 3000 mm/s² to 500 mm/s²).I've changed them to stop the printer from shaking too much.</p>
