|
* -----------------
|
|
* Implemented Codes
|
|
* -----------------
|

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.

* 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 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 mm/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 probe, test the bed, then disengage.
|
|
* Include "E" to engage/disengage the probe for each sample.
|
|
* There's no extra effect if you have a fixed probe.
|
|
* Usage: "G29 E" or "G29 e"
