[Solved] Z Tilt Adjust making bed alignment far worse

[LifeOfBrian]

If your motor assignments are correct then your probe and joint points are not correct.
It is essential that those are measured properly and referenced correctly to 0.0, otherwise the algorithm can’t get it right.
Also possible probe offsets have to be right.

Understanding X and Y Axes Limits and Homing

The X and Y Axis Klipper needs to know from its printer.cfg settings how far the X and Y axes can safely move without hitting the printer’s frame. It also needs to know where the origin (X=0 / Y=0) is. This origin is the beginning of the usable printer bed. In the following, we assume a Cartesian printer that follows the conventions of a Cartesian Coordinate System. This is also the reason why it is a quasi-standard to define the origin as the left-front corner of the bed. This way, all logic…
