Found this interesting info when lookng for CR10 stuff but it will apply to other machines that use the same leadscrew. You might want to set this up in your slicer and see if it makes any difference to quality of the prints.
"The CR-10 has a four start, 2mm pitch, 8mm lead screws which means that for a full step of the Z stepper motor the Z travel is 0.04mm. Although the printer can certainly handle 0.01mm Z steps it is most accurate on full steps. At full steps the stepper motor can hold/lock the Z axis better and there is less chance of a slight Z shift while the print moves around in the X and Y (which causes shaking). Because of that you should get maximum precision on the Z axis when your layer height is an even multiple of 0.04mm.
Use these values with the stock nozzle for layer height for best print quality, regardless of your choice of thin or thick layers. 0.12mm 0.16mm 0.2mm 0.24mm!"
