XYZ Calibration details
Since the release of firmware version 3.0.12, you have an access to a more detailed information about XYZ calibrating results. This new feature can be found in LCD Menu - Support - XYZ cal. details.
The first screen tells you the distance of the “perfect” position of your front 1st, 2nd, and 3rd calibration points. Ideally, all of these are positive and at least 0.5 mm or more. If the margin is between 0 and 0.4 mm, then there is a chance that your calibration will not work all the time. In order to improve your results, you should move with your threaded rods so that all of the points are reachable. When you get your axes perpendicular or slightly skewed, nothing needs to be tweaked as the printer will perform with the best accuracy.
Pressing the button will get you to the second screen. This screen will identify how far you are from the perfect perpendicularity. It is measuring the skew of your X/Y axis.
- Up to 0.25 ° = Severe skew compensating for the offset of 1.1 mm on 250 mm length
- Up to 0.12° = Slight skew compensating for the offset of 0.5 mm on 250 mm length
- Under 0.12° = No need to compensate, X/Y axis are perpendicular. Congratulations!
It may look that the compensations are not that high at the first sight. However, if we take into consideration the 250 mm X-axis length, 1.1 mm is a large margin. In order to improve your axis perpendicularity, make sure the distance of the front calibration points (as seen on the first screen) is the same.
