/**
* G2: Clockwise Arc
* G3: Counterclockwise Arc
*
* This command has two forms: IJ-form and R-form.
*
* - I specifies an X offset. J specifies a Y offset.
* At least one of the IJ parameters is required.
* X and Y can be omitted to do a complete circle.
* The given XY is not error-checked. The arc ends
* based on the angle of the destination.
* Mixing I or J with R will throw an error.
*
* - R specifies the radius. X or Y is required.
* Omitting both X and Y will throw an error.
* X or Y must differ from the current XY.
* Mixing R with I or J will throw an error.
*
* - P specifies the number of full circles to do
* before the specified arc move.
*
* Examples:
*
* G2 I10 ; CW circle centered at X+10
* G3 X20 Y12 R14 ; CCW circle with r=14 ending at X20 Y12

/**
* 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 DEBUG_LEVELING_FEATURE only:
*
* C Make a totally fake grid with no actual probing.
* For use in testing when no probing is possible.
*
* 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
*
* Extra parameters with BILINEAR only:
*
* W Write a mesh point. (If G29 is idle.)
* I X index for mesh point
* J Y index for mesh point
* X X for mesh point, overrides I
* Y Y for mesh point, overrides J
* Z Z for mesh point. Otherwise, raw current Z.
*
* 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.

/**
* Set current_position to the position of the new nozzle.
* Offsets are based on linear distance, so we need to get
* the resulting position in coordinate space.
*
* - With grid or 3-point leveling, offset XYZ by a tilted vector
* - With mesh leveling, update Z for the new position
* - Otherwise, just use the raw linear distance
*
* Software endstops are altered here too. Consider a case where:
* E0 at X=0 ... E1 at X=10
* When we switch to E1 now X=10, but E1 can't move left.
* To express this we apply the change in XY to the software endstops.
* E1 can move farther right than E0, so the right limit is extended.
*
* Note that we don't adjust the Z software endstops. Why not?
* Consider a case where Z=0 (here) and switching to E1 makes Z=1
* because the bed is 1mm lower at the new position. As long as
* the first nozzle is out of the way, the carriage should be
* allowed to move 1mm lower. This technically "breaks" the
* Z software endstop. But this is technically correct (and
* there is no viable alternative).

* 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.
