Hi all, I have a Sovol SV06 Plus running Klipper with the printbed mounted on silicone dampers. This way I can adjust the printbed using the screws along with the “screws tilt calculate” macro.

While this works well, it requires the z-axis to be perpendicular to the x-axis. For this type of printer, an offset can be corrected by holding one of the z-axis rods and rotating the other one until the angle reaches 90°. I do have a hard time measuring or calibrating the angle between the axes.

Do you trust the ‘mechanical gantry calibration’ or do you have a best practice to obtain perfectly aligned axes?
