Описание
The command aims to align the ends of the X gantry (for a Průša i3-style printer). Here’s a
.
Using the given current,
Marlin will move the Z axis (at homing speed) to the top plus a given extra distance.
Since this intentionally stalls the Z steppers, you should use the minimum current required to move the axis.
Z is then re-homed to correct the position.
Примечание
This command is deprecated. Use Z_STEPPER_AUTO_ALIGN instead.
Requires TMC_Z_CALIBRATION and at least one TMC driver for Z axis.
If Z_DUAL_STEPPER_DRIVERS is used, both should be TMC drivers.
