* B # Business Use the 'Business Card' mode of the Manual Probe subsystem. This is invoked as
* G29 P2 B. The mode of G29 P2 allows you to use a business card or recipe card
* as a shim that the nozzle will pinch as it is lowered. The idea is that you
* can easily feel the nozzle getting to the same height by the amount of resistance
* the business card exhibits to movement. You should try to achieve the same amount
* of resistance on each probed point to facilitate accurate and repeatable measurements.
* You should be very careful not to drive the nozzle into the business card with a
* lot of force as it is very possible to cause damage to your printer if your are
* careless. If you use the B option with G29 P2 B you can omit the numeric value
* on first use to measure the business card's thickness. Subsequent usage of 'B'
* will apply the previously-measured thickness as the default.
* Note: A non-compressible Spark Gap feeler gauge is recommended over a Business Card.
* B # Business Use the 'Business Card' mode of the Manual Probe subsystem with P2.
* Note: A non-compressible Spark Gap feeler gauge is recommended over a business card.
* In this mode of G29 P2, a business or index card is used as a shim that the nozzle can
* grab onto as it is lowered. In principle, the nozzle-bed distance is the same when the
* same resistance is felt in the shim. You can omit the numerical value on first invocation
* of G29 P2 B to measure shim thickness. Subsequent use of 'B' will apply the previously-
* measured thickness by default.

* C Continue Continue, Constant, Current Location. This is not a primary command. C is used to
* further refine the behaviour of several other commands. Issuing a G29 P1 C will
* continue the generation of a partially constructed Mesh without invalidating what has
* been done. Issuing a G29 P2 C will tell the Manual Probe subsystem to use the current
* location in its search for the closest unmeasured Mesh Point. When used with a G29 Z C
* it indicates to use the current location instead of defaulting to the center of the print bed.

*
* C Constant G29 P2 C specifies a Constant and tells the Manual Probe subsystem to use the current

* G29 P3 C specifies the Constant for the fill. Otherwise, uses a "reasonable" value.

*
* These points will be handled in Phase 2 and Phase 3. If the Phase 1 command is given the
* C (Continue) parameter it does not invalidate the Mesh prior to automatically
* probing needed locations. This allows you to invalidate portions of the Mesh but still
* use the automatic probing capabilities of the Unified Bed Leveling System. An X and Y
* parameter can be given to prioritize where the command should be trying to measure points.
* If the X and Y parameters are not specified the current probe position is used.
* P1 accepts a 'T' (Topology) parameter so you can observe mesh generation.
* P1 also watches for the LCD Panel Encoder Switch to be held down (assuming you have one),
* and will suspend generation of the Mesh in that case. (Note: This check is only done
* between probe points, so you must press and hold the switch until the Phase 1 command
* detects it.)
* Unreachable points will be handled in Phase 2 and Phase 3.
*
* P2 Phase 2 Probe areas of the Mesh that can't be automatically handled. Phase 2 respects an H
* parameter to control the height between Mesh points. The default height for movement
* between Mesh points is 5mm. A smaller number can be used to make this part of the
* calibration less time consuming. You will be running the nozzle down until it just barely
* touches the glass. You should have the nozzle clean with no plastic obstructing your view.
* Use caution and move slowly. It is possible to damage your printer if you are careless.
* Note that this command will use the configuration #define SIZE_OF_LITTLE_RAISE if the
* nozzle is moving a distance of less than BIG_RAISE_NOT_NEEDED.
* Use 'C' to leave the previous mesh intact and automatically probe needed points. This allows you
* to invalidate parts of the Mesh but still use Automatic Probing.
*
* The H parameter can be set negative if your Mesh dips in a large area. You can press
* and hold the LCD Panel's encoder wheel to terminate the current Phase 2 command. You
* can then re-issue the G29 P 2 command with an H parameter that is more suitable for the
* area you are manually probing. Note that the command tries to start you in a corner
* of the bed where movement will be predictable. You can force the location to be used in
* the distance calculations by using the X and Y parameters. You may find it is helpful to
* print out a Mesh Map (G29 T) to understand where the mesh is invalidated and where
* the nozzle will need to move in order to complete the command. The C parameter is
* available on the Phase 2 command also and indicates the search for points to measure should
* be done based on the current location of the nozzle.
* The 'X' and 'Y' parameters prioritize where to try and measure points. If omitted, the current
* probe position is used.
*
* A B parameter is also available for this command and described up above. It places the
* manual probe subsystem into Business Card mode where the thickness of a business card is
* measured and then used to accurately set the nozzle height in all manual probing for the
* duration of the command. (S for Shim mode would be a better parameter name, but S is needed
* for Save or Store of the Mesh to EEPROM) A Business card can be used, but you will have
* better results if you use a flexible Shim that does not compress very much. That makes it
* easier for you to get the nozzle to press with similar amounts of force against the shim so you
* can get accurate measurements. As you are starting to touch the nozzle against the shim try
* to get it to grasp the shim with the same force as when you measured the thickness of the
* shim at the start of the command.
* Use 'T' (Topology) to generate a report of mesh generation.
*
* Phase 2 allows the T (Map) parameter to be specified. This helps the user see the progression
* of the Mesh being built.
* P1 will suspend Mesh generation if the controller button is held down. Note that you may need
* to press and hold the switch for several seconds if moves are underway.
*
* NOTE: P2 is not available unless you have LCD support enabled!
* P2 Phase 2 Probe unreachable points.
*
* P3 Phase 3 Fill the unpopulated regions of the Mesh with a fixed value. There are two different paths the
* user can go down. If the user specifies the value using the C parameter, the closest invalid
* mesh points to the nozzle will be filled. The user can specify a repeat count using the R
* parameter with the C version of the command.
* Use 'H' to set the height between Mesh points. If omitted, Z_CLEARANCE_BETWEEN_PROBES is used.
* Smaller values will be quicker. Move the nozzle down till it barely touches the bed. Make sure the
* nozzle is clean and unobstructed. Use caution and move slowly. This can damage your printer!
* (Uses SIZE_OF_LITTLE_RAISE mm if the nozzle is moving less than BIG_RAISE_NOT_NEEDED mm.)
*
* A second version of the fill command is available if no C constant is specified. Not
* specifying a C constant will invoke the 'Smart Fill' algorithm. The G29 P3 command will search
* from the edges of the mesh inward looking for invalid mesh points. It will look at the next
* several mesh points to determine if the print bed is sloped up or down. If the bed is sloped
* upward from the invalid mesh point, it will be replaced with the value of the nearest mesh point.
* If the bed is sloped downward from the invalid mesh point, it will be replaced with a value that
* puts all three points in a line. The second version of the G29 P3 command is a quick, easy and
* usually safe way to populate the unprobed regions of your mesh so you can continue to the G26
* Mesh Validation Pattern phase. Please note that you are populating your mesh with unverified
* numbers. You should use some scrutiny and caution.
* The 'H' value can be negative if the Mesh dips in a large area. Press and hold the
* controller button to terminate the current Phase 2 command. You can then re-issue "G29 P 2"
* with an 'H' parameter more suitable for the area you're manually probing. Note that the command
* tries to start in a corner of the bed where movement will be predictable. Override the distance
* calculation location with the X and Y parameters. You can print a Mesh Map (G29 T) to see where
* the mesh is invalidated and where the nozzle needs to move to complete the command. Use 'C' to
* indicate that the search should be based on the current position.
*
* P4 Phase 4 Fine tune the Mesh. The Delta Mesh Compensation System assume the existence of
* an LCD Panel. It is possible to fine tune the mesh without the use of an LCD Panel using
* G42 and M421; see the UBL documentation for further details.
* The 'B' parameter for this command is described above. It places the manual probe subsystem into
* Business Card mode where the thickness of a business card is measured and then used to accurately
* set the nozzle height in all manual probing for the duration of the command. A Business card can
* be used, but you'll get better results with a flexible Shim that doesn't compress. This makes it
* easier to produce similar amounts of force and get more accurate measurements. Google if you're
* not sure how to use a shim.
*
* The System will search for the closest Mesh Point to the nozzle. It will move the
* nozzle to this location. The user can use the LCD Panel to carefully adjust the nozzle
* so it is just barely touching the bed. When the user clicks the control, the System
* will lock in that height for that point in the Mesh Compensation System.
* The 'T' (Map) parameter helps track Mesh building progress.
*
* Phase 4 has several additional parameters that the user may find helpful. Phase 4
* can be started at a specific location by specifying an X and Y parameter. Phase 4
* can be requested to continue the adjustment of Mesh Points by using the R(epeat)
* parameter. If the Repetition count is not specified, it is assumed the user wishes
* to adjust the entire matrix. The nozzle is moved to the Mesh Point being edited.
* The command can be terminated early (or after the area of interest has been edited) by
* pressing and holding the encoder wheel until the system recognizes the exit request.
* Phase 4's general form is G29 P4 [R # of points] [X position] [Y position]
* NOTE: P2 requires an LCD controller!
*
* Phase 4 is intended to be used with the G26 Mesh Validation Command. Using the
* information left on the printer's bed from the G26 command it is very straight forward
* and easy to fine tune the Mesh. One concept that is important to remember and that
* will make using the Phase 4 command easy to use is this: You are editing the Mesh Points.
* If you have too little clearance and not much plastic was extruded in an area, you want to
* LOWER the Mesh Point at the location. If you did not get good adheasion, you want to
* RAISE the Mesh Point at that location.
* P3 Phase 3 Fill the unpopulated regions of the Mesh with a fixed value. There are two different paths to
* go down:
*
* - If a 'C' constant is specified, the closest invalid mesh points to the nozzle will be filled,
* and a repeat count can then also be specified with 'R'.
*
* - Leaving out 'C' invokes Smart Fill, which scans the mesh from the edges inward looking for
* invalid mesh points. Adjacent points are used to determine the bed slope. If the bed is sloped
* upward from the invalid point, it takes the value of the nearest point. If sloped downward, it's
* replaced by a value that puts all three points in a line. This version of G29 P3 is a quick, easy
* and (usually) safe way to populate unprobed mesh regions before continuing to G26 Mesh Validation
* Pattern. Note that this populates the mesh with unverified values. Pay attention and use caution.
*
* P4 Phase 4 Fine tune the Mesh. The Delta Mesh Compensation System assumes the existence of
* an LCD Panel. It is possible to fine tune the mesh without an LCD Panel using
* G42 and M421. See the UBL documentation for further details.
*
* Phase 4 is meant to be used with G26 Mesh Validation to fine tune the mesh by direct editing
* of Mesh Points. Raise and lower points to fine tune the mesh until it gives consistently reliable
* adhesion.
*
* P4 moves to the closest Mesh Point (and/or the given X Y), raises the nozzle above the mesh height
* by the given 'H' offset (or default Z_CLEARANCE_BETWEEN_PROBES), and waits while the controller is
* used to adjust the nozzle height. On click the displayed height is saved in the mesh.
*
* Start Phase 4 at a specific location with X and Y. Adjust a specific number of Mesh Points with
* the 'R' (Repeat) parameter. (If 'R' is left out, the whole matrix is assumed.) This command can be
* terminated early (e.g., after editing the area of interest) by pressing and holding the encoder button.
*
* The general form is G29 P4 [R points] [X position] [Y position]
*
* The H [offset] parameter is useful if a shim is used to fine-tune the mesh. For a 0.4mm shim the
* command would be G29 P4 H0.4. The nozzle is moved to the shim height, you adjust height to the shim,
* and on click the height minus the shim thickness will be saved in the mesh.
*
* !!Use with caution, as a very poor mesh could cause the nozzle to crash into the bed!!
*
* NOTE: P4 is not available unless you have LCD support enabled!
