/**
* G29: Detailed Z probe, probes the bed at 3 or more points.
* Will fail if the printer has not been homed with G28.
*
* Enhanced G29 Auto Bed Leveling Probe Routine
*
* D Dry-Run mode. Just evaluate the bed Topology - Don't apply
* or alter the bed level data. Useful to check the topology
* after a first run of G29.
*
* J Jettison current bed leveling data
*
* V Set the verbose level (0-4). Example: "G29 V3"
*
* Parameters With LINEAR leveling only:
*
* P Set the size of the grid that will be probed (P x P points).
* Example: "G29 P4"
*
* X Set the X size of the grid that will be probed (X x Y points).
* Example: "G29 X7 Y5"
*
* Y Set the Y size of the grid that will be probed (X x Y points).
*
* T Generate a Bed Topology Report. Example: "G29 P5 T" for a detailed report.
* This is useful for manual bed leveling and finding flaws in the bed (to
* assist with part placement).
* Not supported by non-linear delta printer bed leveling.
*
* Parameters With LINEAR and BILINEAR leveling only:
*
* S Set the XY travel speed between probe points (in units/min)
*
* F Set the Front limit of the probing grid
* B Set the Back limit of the probing grid
* L Set the Left limit of the probing grid
* R Set the Right limit of the probing grid
*
* Parameters with BILINEAR leveling only:
*
* Z Supply an additional Z probe offset
*
* Extra parameters with PROBE_MANUALLY:
*
* To do manual probing simply repeat G29 until the procedure is complete.
* The first G29 accepts parameters. 'G29 Q' for status, 'G29 A' to abort.
*
* Q Query leveling and G29 state
*
* A Abort current leveling procedure
*
* W Write a mesh point. (Ignored during leveling.)
* X Required X for mesh point
* Y Required Y for mesh point
* Z Required Z for mesh point
*
* Without PROBE_MANUALLY:
*
* E By default G29 will engage the Z probe, test the bed, then disengage.
* Include "E" to engage/disengage the Z probe for each sample.
* There's no extra effect if you have a fixed Z probe.

* r_T = [cos(phi) -sin(phi);
* sin(phi) cos(phi)] * r ;
*
* For arc generation, the center of the circle is the axis of rotation and the radius vector is
* defined from the circle center to the initial position. Each line segment is formed by successive
* vector rotations. This requires only two cos() and sin() computations to form the rotation
* matrix for the duration of the entire arc. Error may accumulate from numerical round-off, since
* all double numbers are single precision on the Arduino. (True double precision will not have
* round off issues for CNC applications.) Single precision error can accumulate to be greater than
* tool precision in some cases. Therefore, arc path correction is implemented.
*
* Small angle approximation may be used to reduce computation overhead further. This approximation
* holds for everything, but very small circles and large MM_PER_ARC_SEGMENT values. In other words,
* theta_per_segment would need to be greater than 0.1 rad and N_ARC_CORRECTION would need to be large
* to cause an appreciable drift error. N_ARC_CORRECTION~=25 is more than small enough to correct for
* numerical drift error. N_ARC_CORRECTION may be on the order a hundred(s) before error becomes an
* issue for CNC machines with the single precision Arduino calculations.
*
* This approximation also allows plan_arc to immediately insert a line segment into the planner
* without the initial overhead of computing cos() or sin(). By the time the arc needs to be applied
* a correction, the planner should have caught up to the lag caused by the initial plan_arc overhead.
* This is important when there are successive arc motions.
