* 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 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.
|
|
*
|
|
* 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.
|
|
*
|
|
* 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 'T' parameter is also available 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 'T' 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.
|
|
*
|
|
* J # Grid Perform a Grid Based Leveling of the current Mesh using a grid with n points on a side.
|
|
* Not specifying a grid size will invoke the 3-Point leveling function.
|
|
*
|
|
* 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.
|
|
*
|
|
* 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 compatibility.
|
|
*
|
|
* P1 Phase 1 Invalidate entire Mesh and continue with automatic generation of the Mesh data using
|
|
* the Z-Probe. Usually the probe can not reach all areas that the nozzle can reach.
|
|
* In Cartesian printers, mesh points within the X_OFFSET_FROM_EXTRUDER and Y_OFFSET_FROM_EXTRUDER
|
|
* area can not be automatically probed. For Delta printers the area in which DELTA_PROBEABLE_RADIUS
|
|
* and DELTA_PRINTABLE_RADIUS do not overlap will not be automatically probed.
|
|
*
|
|
* 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, 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.)
|
|
*
|
|
* 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.
|
|
*
|
|
* 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.
|
|
*
|
|
* 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.
|
|
*
|
|
* Phase 2 allows the T (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. 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.
|
|
*
|
|
* 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.
|
|
*
|
|
* 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.
|
|
* (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.
|
|
*
|
|
* R # Repeat Repeat this command the specified number of times. If no number is specified the
|
|
* command will be repeated GRID_MAX_POINTS_X * GRID_MAX_POINTS_Y times.
|
|
*
|
|
* 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. Valid storage slot numbers begin at 0 and
|
|
* extend to a limit related to the available EEPROM storage.
|
|
*
|
|
* 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 GCode output can be saved and later replayed by the host software
|
|
* to reconstruct the current mesh on another machine.
|
|
*
|
|
* T Topology Display the Mesh Map Topology.
|
|
* 'T' can be used alone (e.g., G29 T) or in combination with most of the other commands.
|
|
* This option works with all Phase commands (e.g., G29 P4 R 5 T X 50 Y100 C -.1 O)
|
|
* This parameter can also specify a Map Type. T0 (the default) is user-readable. T1 can
|
|
* is suitable to paste into a spreadsheet for a 3D graph of the mesh.
|
|
*
|
|
* U Unlevel Perform a probe of the outer perimeter to assist in physically leveling unlevel beds.
|
|
* Only used for G29 P1 T U. This speeds up the probing of the edge of the bed. Useful
|
|
* when the entire bed doesn't need to be probed because it will be adjusted.
|
|
*
|
|
* V # Verbosity Set the verbosity level (0-4) for extra details. (Default 0)
|
|
*
|
|
* W What? Display valuable Unified Bed Leveling System data.
|
|
*
|
|
* X # X Location for this command
|
|
*
|
|
* Y # Y Location for this command
|
|
*
|
|
*
|
|
* 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 their contributions
|
|
* we now have the functionality and features of all three systems combined.
