[FR] G34 doesn't respect the X-axis twist compensation #27058

Is your feature request related to a problem? Please describe.

In it's current implementation the G34 Z-stepper auto align command does not respect any compensation values set through the (relatively) new X-twist wizard. This causes the gantry to be out of alignment after running G34 and following ABL procedures to produce useless mesh values.

Right now the G34 command is pretty much useless on machines with a twisted X-axis and setting the stepper alignment has to be done manually to get meaningful mesh bed leveling results.

Are you looking for hardware support?
