MarlinFirmware/Marlin/Marlin_main.cpp
AnHardt 5126cce7fd Move Allen Key probe move scripts to their own functions 
There was an hidden extra move after the scripts. This is configurable now.
Added the extra moves to the relevant configs.

* G29: Detailed Z probe, probes the bed at 3 or more points.

*
* Enhanced G29 Auto Bed Leveling Probe Routine
*
* Parameters With AUTO_BED_LEVELING_GRID:
*
* P Set the size of the grid that will be probed (P x P points).
* Not supported by non-linear delta printer bed leveling.
* Example: "G29 P4"
*
* S Set the XY travel speed between probe points (in units/min)
*
* D Dry-Run mode. Just evaluate the bed Topology - Don't apply
* or clean the rotation Matrix. Useful to check the topology
* after a first run of G29.
*
* V Set the verbose level (0-4). Example: "G29 V3"
*
* 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.
*
* 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
*
* Global Parameters:
*
* E/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.
* Usage: "G29 E" or "G29 e"

* Vector rotation by transformation matrix: r is the original vector, r_T is the rotated vector,
* and phi is the angle of rotation. Based on the solution approach by Jens Geisler.
* 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.
