I realize this is somewhat of a first-world problem, but when I drag a model into Cura, what I see at the “front” ends up being in the back corner of the printer (where the power cable is).
Can Klipper maybe rotate the print on the build plate using a config setting? Preferably without having to calibrate again.
The X and Y coordinates are ultimately determined by the steppers defined in the stepper_a, stepper_b, and stepper_c config sections. If you rotate the steppers, you’ll also effectively rotate the coordinate system. See the description at Configuration reference - Klipper documentation
If you change the config it’s a good idea to redo the calibration.
