Calibrating the XYZprinting DaVinci 1.0/1.0A & 2.0/2.0A Duo 3D Printers can be a burdensome, confusing and frustrating process. This Calibration Aid simplifies that process by determining what adjustments are needed. Simply run the DaVinci Calibration Utility, enter the results into the App, and pick a target platform height. The Calibration Aid shows how far and in what direction each adjusting screw needs to be turned. Units can be tailored to your personal preferences and to suit the amount of adjustment needed.
