|
* 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 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 G29 P1 C continues the generation of a partially-constructed Mesh without invalidating
|
|
* previous measurements.
|
|
*
|
|
* C Constant G29 P2 C specifies a Constant and tells the Manual Probe subsystem to use the current
|
|
* location in its search for the closest unmeasured Mesh Point.
|
|
*
|
|
* G29 P3 C specifies the Constant for the fill. Otherwise, uses a "reasonable" value.
|
|
*
|
|
* C Current G29 Z C uses the Current location (instead of bed center or nearest edge).
|
|
*
|
|
* 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 With P2, 'H' specifies the Height to raise the nozzle after each manual probe of the bed.
|
|
* If omitted, the nozzle will raise by Z_CLEARANCE_BETWEEN_PROBES.
|
|
*
|
|
* H # Offset With P4, 'H' specifies the Offset above the mesh height to place the nozzle.
|
|
* If omitted, Z_CLEARANCE_BETWEEN_PROBES will be used.
|
|
*
|
|
* I # Invalidate Invalidate the specified number of Mesh Points near the given 'X' 'Y'. If X or Y are omitted,
|
|
* the nozzle location is used. If no 'I' value is given, only the point nearest to the location
|
|
* is invalidated. Use 'T' to produce a map afterward. This command is useful to invalidate a
|
|
* portion of the Mesh so it can be adjusted using other UBL tools. When attempting to invalidate
|
|
* an isolated bad mesh point, the 'T' option shows the nozzle position in the Mesh with (#). You
|
|
* can move the nozzle around and use this feature to select the center of the area (or cell) 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't reach all areas that the nozzle can reach. On
|
|
* Cartesian printers, points within the X_PROBE_OFFSET_FROM_EXTRUDER and Y_PROBE_OFFSET_FROM_EXTRUDER
|
|
* area cannot 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.
|
|
*
|
|
* Unreachable points will be handled in Phase 2 and Phase 3.
|
|
*
|
|
* 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 'X' and 'Y' parameters prioritize where to try and measure points. If omitted, the current
|
|
* probe position is used.
|
|
*
|
|
* Use 'T' (Topology) to generate a report of mesh generation.
|
|
*
|
|
* 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.
|
|
*
|
|
* P2 Phase 2 Probe unreachable points.
|
|
*
|
|
* 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.)
|
|
*
|
|
* 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.
|
|
*
|
|
* 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 'T' (Map) parameter helps track Mesh building progress.
|
|
*
|
|
* NOTE: P2 requires an LCD controller!
|
|
*
|
|
* 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!
|
|
*
|
|
* 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.
