Dimensional Accuracy in the Z Axis

Is there any way to improve Z axis accuracy?

I have not invested much time with parameters to see how to dial it in, but I printed a part that is 0.320” high and that printed part was measured as 0.326” high.

I’m printing generic PCTG with a 0.2mm height for initial and subsequent layers on the build plate that comes with the unit.

The X and Y dimensions have some inaccuracies, but maybe the vision plate might help.
