/**
* 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 :
* 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 ) .
* Not supported by non - linear delta printer bed leveling .
* Example : " G29 P4 "
*
* S Set the XY travel speed between probe points ( in units / min )
* X Set the X size of the grid that will be probed ( X x Y points ) .
* Example : " G29 X7 Y5 "
*
* 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 "
* 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 only :
* Parameters with BILINEAR leveling only :
*
* Z Supply an additional Z probe offset
*
* Global Parameters :
* 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 .
*
* E / e By default G29 will engage the Z probe , test the bed , then disengage .
* 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 .
* Usage : " G29 E " or " G29 e "
