Maybe this helps
So essentially you are dealing with 3 different coordinate systems:
- The kinematic limits and the origin are set via the Klipper config
- The effective size needs to be set in the slicer → The “center” as seen by the slicer is relative to the effective size and not necessarily to the bed size. It makes no sense to provide a bigger bed to slicer that potentially cannot be reached by the nozzle
- All values relate to the nozzle coordinates
