/**
* G34: Z-Stepper automatic alignment
*
* I<iterations>
* T<accuracy>
* A<amplification>
* R<recalculate> points based on current probe offsets
* Manual stepper lock controls (reset by G28):
* L Unlock all steppers
* Z<1-4> Z stepper to lock / unlock
* S<state> 0=UNLOCKED 1=LOCKED. If omitted, assume LOCKED.
*
* Examples:
* G34 Z1 ; Lock Z1
* G34 L Z2 ; Unlock all, then lock Z2
* G34 Z2 S0 ; Unlock Z2
*
* With Z_STEPPER_AUTO_ALIGN:
* I<iterations> Number of tests. If omitted, Z_STEPPER_ALIGN_ITERATIONS.
* T<accuracy> Target Accuracy factor. If omitted, Z_STEPPER_ALIGN_ACC.
* A<amplification> Provide an Amplification value. If omitted, Z_STEPPER_ALIGN_AMP.
* R Flag to recalculate points based on current probe offsets
