/**
* G29: Unified Bed Leveling by Roxy
*
* Parameters understood by this leveling system:
*
* A Activate Activate the Unified Bed Leveling system.
*
* 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 bussiness 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 bussiness 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 leave the number parameter off
* on its first use to enable measurement of the business card thickness. Subsequent usage
* of the B parameter can have the number previously measured supplied to the command.
* Incidently, you are much better off using something like a Spark Gap feeler gauge than
* something that compresses like a Business Card.
*
* 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.
*
* D Disable Disable the Unified Bed Leveling system.
*
* E Stow_probe Stow the probe after each sampled point.
*
* F # Fade * Fade the amount of Mesh Based Compensation over a specified height. At the
* specified height, no correction is applied and natural printer kenimatics take over. If no
* number is specified for the command, 10mm is assumed to be reasonable.
*
* G # Grid * Perform a Grid Based Leveling of the current Mesh using a grid with n points on a side.
*
* H # Height Specify the Height to raise the nozzle after each manual probe of the bed. The
* default is 5mm.
*
* I # Invalidate Invalidate specified number of Mesh Points. The nozzle location is used unless
* the X and Y parameter are used. If no number is specified, only the closest Mesh
* point to the location is invalidated. The M parameter is available as well to produce
* a map after the operation. This command is useful to invalidate a portion of the
* Mesh so it can be adjusted using other tools in the Unified Bed Leveling System. When
* attempting to invalidate an isolated bad point in the mesh, the M option will indicate
* where the nozzle is positioned in the Mesh with (#). You can move the nozzle around on
* the bed and use this feature to select the center of the area (or cell) you want to
* invalidate.
*
* K # Kompare Kompare current Mesh with stored Mesh # replacing current Mesh with the result. This
* command literally performs a diff between two Meshes.
*
* L Load * Load Mesh from the previously activated location in the EEPROM.
*
* L # Load * Load Mesh from the specified location in the EEPROM. Set this location as activated
* for subsequent Load and Store operations.
*
* O Map * Display the Mesh Map Topology.
* The parameter can be specified alone (ie. G29 O) or in combination with many of the
* other commands. The Mesh Map option works with all of the Phase
* commands (ie. G29 P4 R 5 X 50 Y100 C -.1 O)
*
* N No Home G29 normally insists that a G28 has been performed. You can over rule this with an
* N option. In general, you should not do this. This can only be done safely with
* commands that do not move the nozzle.
*
* The P or Phase commands are used for the bulk of the work to setup a Mesh. In general, your Mesh will
* start off being initialized with a G29 P0 or a G29 P1. Further refinement of the Mesh happens with
* each additional Phase that processes it.
*
* P0 Phase 0 Zero Mesh Data and turn off the Mesh Compensation System. This reverts the
* 3D Printer to the same state it was in before the Unified Bed Leveling Compensation
* was turned on. Setting the entire Mesh to Zero is a special case that allows
* a subsequent G or T leveling operation for backward compatability.
*
* P1 Phase 1 Invalidate entire Mesh and continue with automatic generation of the Mesh data using
* the Z-Probe. Depending upon the values of DELTA_PROBEABLE_RADIUS and
* DELTA_PRINTABLE_RADIUS some area of the bed will not have Mesh Data automatically
* generated. This will be handled in Phase 2. 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. Phase 1
* allows you to specify the M (Map) parameter so you can watch the generation of the Mesh.
* Phase 1 also watches for the LCD Panel's Encoder Switch being held in a depressed state.
* It will suspend generation of the Mesh if it sees the user request that. (This check is
* only done between probe points. You will need to press and hold the switch until the
* Phase 1 command can detect it.)
*
* P2 Phase 2 Probe areas of the Mesh that can not 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.
*
* 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 O ) 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.
*
* 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 care 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.
*
* Phase 2 allows the O (Map) parameter to be specified. This helps the user see the progression
* of the Mesh being built.
*
* P3 Phase 3 Fill the unpopulated regions of the Mesh with a fixed value. The C parameter is
* used to specify the 'constant' value to fill all invalid areas of the Mesh. If no C parameter
* is specified, a value of 0.0 is assumed. The R parameter can be given to specify the number
* of points to set. If the R parameter is specified the current nozzle position is used to
* find the closest points to alter unless the X and Y parameter are used to specify the fill
* location.
*
* P4 Phase 4 Fine tune the Mesh. The Delta Mesh Compensation System assume the existance of
* an LCD Panel. It is possible to fine tune the mesh without the use of an LCD Panel.
* (More work and details on doing this later!)
* 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.
*
* 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]
*
* 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.
*
*
* P5 Phase 5 Find Mean Mesh Height and Standard Deviation. Typically, it is easier to use and
* work with the Mesh if it is Mean Adjusted. You can specify a C parameter to
* Correct the Mesh to a 0.00 Mean Height. Adding a C parameter will automatically
* execute a G29 P6 C <mean height>.
*
* P6 Phase 6 Shift Mesh height. The entire Mesh's height is adjusted by the height specified
* with the C parameter. Being able to adjust the height of a Mesh is useful tool. It
* can be used to compensate for poorly calibrated Z-Probes and other errors. Ideally,
* you should have the Mesh adjusted for a Mean Height of 0.00 and the Z-Probe measuring
* 0.000 at the Z Home location.
*
* Q Test * Load specified Test Pattern to assist in checking correct operation of system. This
* command is not anticipated to be of much value to the typical user. It is intended
* for developers to help them verify correct operation of the Unified Bed Leveling System.
*
* S Store Store the current Mesh in the Activated area of the EEPROM. It will also store the
* current state of the Unified Bed Leveling system in the EEPROM.
*
* S # Store Store the current Mesh at the specified location in EEPROM. Activate this location
* for subsequent Load and Store operations. It will also store the current state of
* the Unified Bed Leveling system in the EEPROM.
*
* S -1 Store Store the current Mesh as a print out that is suitable to be feed back into
* the system at a later date. The text generated can be saved and later sent by PronterFace or
* Repetier Host to reconstruct the current mesh on another machine.
*
* T 3-Point Perform a 3 Point Bed Leveling on the current Mesh
*
* W What? Display valuable data the Unified Bed Leveling System knows.
*
* X # * * X Location for this line of commands
*
* Y # * * Y Location for this line of commands
*
* Z Zero * Probes to set the Z Height of the nozzle. The entire Mesh can be raised or lowered
* by just doing a G29 Z
*
* Z # Zero * The entire Mesh can be raised or lowered to conform with the specified difference.
* zprobe_zoffset is added to the calculation.
*
*
* Release Notes:
* You MUST do M502, M500 to initialize the storage. Failure to do this will cause all
* kinds of problems. Enabling EEPROM Storage is highly recommended. With EEPROM Storage
* of the mesh, you are limited to 3-Point and Grid Leveling. (G29 P0 T and G29 P0 G
* respectively.)
*
* When you do a G28 and then a G29 P1 to automatically build your first mesh, you are going to notice
* the Unified Bed Leveling probes points further and further away from the starting location. (The
* starting location defaults to the center of the bed.) The original Grid and Mesh leveling used
* a Zig Zag pattern. The new pattern is better, especially for people with Delta printers. This
* allows you to get the center area of the Mesh populated (and edited) quicker. This allows you to
* perform a small print and check out your settings quicker. You do not need to populate the
* entire mesh to use it. (You don't want to spend a lot of time generating a mesh only to realize
* you don't have the resolution or zprobe_zoffset set correctly. The Mesh generation
* gathers points closest to where the nozzle is located unless you specify an (X,Y) coordinate pair.
*
* The Unified Bed Leveling uses a lot of EEPROM storage to hold its data. And it takes some effort
* to get this Mesh data correct for a user's printer. We do not want this data destroyed as
* new versions of Marlin add or subtract to the items stored in EEPROM. So, for the benefit of
* the users, we store the Mesh data at the end of the EEPROM and do not keep it contiguous with the
* other data stored in the EEPROM. (For sure the developers are going to complain about this, but
* this is going to be helpful to the users!)
*
* The foundation of this Bed Leveling System is built on Epatel's Mesh Bed Leveling code. A big
* 'Thanks!' to him and the creators of 3-Point and Grid Based leveling. Combining thier contributions
* we now have the functionality and features of all three systems combined.
