/**
* G33 - Delta '1-4-7-point' auto calibration (Requires DELTA)
*
* Usage:
* G33 <Vn> <Pn> <A> <O> <T>
*
* Vn = verbose level (n=0-2 default 1)
* n=0 dry-run mode: setting + probe results / no calibration
* n=1 settings
* n=2 setting + probe results
* Pn = n=-7 -> +7 : n*n probe points
* calibrates height ('1 point'), endstops, and delta radius ('4 points')
* and tower angles with n > 2 ('7+ points')
* n=1 probes center / sets height only
* n=2 probes center and towers / sets height, endstops and delta radius
* n=3 probes all points: center, towers and opposite towers / sets all
* n>3 probes all points multiple times and averages
* A = abort 1 point delta height calibration after 1 probe
* O = use oposite tower points instead of tower points with 4 point calibration
* T = do not calibrate tower angles with 7+ point calibration
* G33 - Delta '1-4-7-point' Auto-Calibration
* Calibrate height, endstops, delta radius, and tower angles.
*
* Parameters:
*
* P Number of probe points:
*
* P1 Probe center and set height only.
* P2 Probe center and towers. Set height, endstops, and delta radius.
* P3 Probe all positions: center, towers and opposite towers. Set all.
* P4-P7 Probe all positions at different locations and average them.
*
* A Abort delta height calibration after 1 probe (only P1)
*
* O Use opposite tower points instead of tower points (only P2)
*
* T Don't calibrate tower angle corrections (P3-P7)
*
* V Verbose level:
*
* V0 Dry-run mode. Report settings and probe results. No calibration.
* V1 Report settings
* V2 Report settings and probe results
