Can you first determine the source of the inaccuracy? It could be inconsistency between layers (having them slightly off from one another) or consistent positioning error causing expansion, or just overextrusion.

I recently calibrated e-steps on the extruder, so I wouldn't think it is due to over extrusion.

(Asked by: username_0 on 2021-01-08)

I have a `delta` printer that I am trying to fine tune. I have printed a 20mm calibration cube and I get the following measurements:

* X: 20.5
* Y: 20.3
* Z: 20.0

How can I calibrate my printer to improve the accuracy of x and y ?
