Firmware2/Marlin/Marlin_main.cpp
Colin Gilgenbach 48b7e0f8d8 Nozzle Wipe Vertical Zig-Zag 
- Add configuration support for zigzags in either the X or Y axis, for
wipe pads significantly longer in one dimension.
- Add configuration for default number of zig-zag triangles, vs. a
magic number in `Marlin_main.cpp`.
- Update description of auto nozzle wiping to match functionality

/**
* 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
*
* Parameters With LINEAR and BILINEAR:
*
* 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
*
* Parameters with BILINEAR only:
*
* Z Supply an additional Z probe offset
*
* 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"

* 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.
