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 . * * 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.) * * Z-Probe Sleds are not currently fully supported. There were too many complications caused * by them to support them in the Unified Bed Leveling code. Support for them will be handled * better in the upcoming Z-Probe Object that will happen during the Code Clean Up phase. (That * is what they really are: A special case of the Z-Probe.) When a Z-Probe Object appears, it * should slip in under the Unified Bed Leveling code without major trauma. * * 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. */ int ubl_eeprom_start = -1; bool ubl_has_control_of_lcd_panel = false; volatile uint8_t ubl_encoderDiff = 0; // Volatile because it's changed by Temperature ISR button update // The simple parameter flags and values are 'static' so parameter parsing can be in a support routine. static int g29_verbose_level = 0, test_value = 0, phase_value = -1, repetition_cnt = 1; static bool repeat_flag = UBL_OK, c_flag = false, x_flag = UBL_OK, y_flag = UBL_OK, statistics_flag = UBL_OK, business_card_mode = false; static float x_pos = 0.0, y_pos = 0.0, height_value = 5.0, measured_z, card_thickness = 0.0, constant = 0.0; static int storage_slot = 0, test_pattern = 0; #if ENABLED(ULTRA_LCD) void lcd_setstatus(const char* message, bool persist); #endif void gcode_G29() { mesh_index_pair location; int j, k; float Z1, Z2, Z3; g29_verbose_level = 0; // These may change, but let's get some reasonable values into them. repeat_flag = UBL_OK; repetition_cnt = 1; c_flag = false; SERIAL_PROTOCOLLNPAIR("ubl_eeprom_start=", ubl_eeprom_start); if (ubl_eeprom_start < 0) { SERIAL_PROTOCOLLNPGM("?You need to enable your EEPROM and initialize it"); SERIAL_PROTOCOLLNPGM("with M502, M500, M501 in that order.\n"); return; } if (!code_seen('N') && axis_unhomed_error(true, true, true)) // Don't allow auto-leveling without homing first gcode_G28(); if (g29_parameter_parsing()) return; // abort if parsing the simple parameters causes a problem, // Invalidate Mesh Points.
