The Th4D article "Storing Bed Leveling Mesh & Updating Your Slicer" I think can help.
A summary of that write-up:
Send a G28
Preheat the machine to your normal print temperature. Let the printer sit at temperature for 5 minutes to let everything expand as it heats
Send a G28
Send a G29
Send M500
After doing these steps the mesh is now stored in the printer EEPROM.
Then: Update your slicer to use the stored mesh
Load your slicer and open up the settings where the starting G-code is stored
Replace the G29 with M420 S1 (2.5 If you want to use ABL fading use M420 S1 Z10 – This will fade ABL compensation until it is off over the first 10 mm of the print.)
Slice up some files!

marlin - G29 Auto Grid Leveling Doesn't Do Anything
I have an Ender 3 Pro, recently added a BLTouch v3, flashed a bootloader, and I'm now attempting to configure Th4D U1.R2.15 firmware.
I have only modified configuration.h, haven't touched any other file, and configured it using the inline comments as a guide.
Everything seems to work ok, apart from it doesn't do a grid/mesh level before the print. G29 has been added just after G28 in Cura in the Start gcode box.
When I print something, this happens:
Bed + hotend heats up.
X/Y get homed.
Nozzle moves to the center.
BLTouch slowly comes down to probe the bed twice to set the level based on that one single center point.
Primes the filament and begins the print...
I'm not sure what the correct sequence is but I would have thought it should probe 9 points in a grid as I have set #define EZABL_POINTS 3.
Have I missed something in the config?
configuration.h (have omitted all other printer sections to allow stackexchange to accept the rest of the file)

Desktop Auto-Calibration is a feature available on some FDM 3D printers by default from the factory. In addition, experienced technicians can install the auto-calibration sensor themselves.
In this article we will tell you what this function is for and how to use it.
Why Calibrate the Platen
Most FDM 3D printers are devices that require the active participation of the master in the process of preparing for printing. One of the features of the devices is the need to regularly check the level of the printed table. Over time, the design of an FDM 3D printer can become loose. And this is due not only to the adjusting screws of the table, but also to the backlash of absolutely all screw connections. Most often this is manifested in vibrations during the printing process.
Source: pinshape.com
As a result of the deviation of the table from the set level, the distance between the extruder nozzle and the printing table changes, by different distances at different points. This can lead to deformation of the printed model, distortion of dimensions and proportions, clogging of the extruder (when the nozzle is close to the table and the plastic cannot come out).
This may be caused by a missing thread lock and poor quality platform leveling screws. Also, the error can be caused by the user's actions, for example, if he unevenly pasted adhesive tape on the printed table. nine0005
To avoid problems, the user should calibrate the platen regularly. In budget models, this work is done manually. To do this, the table is equipped with adjusting screws. However, there are models of 3D printers on the market with auto-calibration of the print bed, which greatly simplifies the operation of the printer.
The principle of auto-calibration of the 3D printer table
Source: all3dp.com
As follows from the definition, auto-calibration of the 3D printer table is a mechanism that allows you to automatically adjust the device. Before printing, the 3D printer determines the position of the print bed relative to the extruder and, if necessary, adjusts the position of the nozzle during printing. nine0005
Typically, an auto-leveling 3D printer has a proximity sensor or contact tip sensor at the level of the print head nozzle that "probes" certain points on the platform when the auto-calibration process is initiated. Sometimes, equipped with a feedback encoder, the extruder itself serves as such a sensor, and the nozzle is its probe.
One of the advantages of auto calibration is that it allows you to print a quality product, even if there are visually imperceptible irregularities on the table. Such a situation may occur during long-term operation of the device at high heating temperatures of the printing table. nine0005
Since the 3D printer automatically adjusts the position of the nozzle relative to the plane, the nozzle is always at the optimal distance from the printed model during the operation of the device. This, in particular, improves the adhesion of layers and print quality.
When using non-professional FDM 3D printers, especially from the DIY category (self-assembled, supplied as a kit), there are extensive upgrade options, including the ability to install the sensor required for auto-calibration. nine0005
Auto-calibration using the example of Simplify3D
Source: simplify3d.com
Consider setting up auto-calibration using one of the most popular professional 3D printing software, Simplify3D, as an example.
If the 3D printer has an automatic build plate alignment feature, then the Simplify3D profile for the machine must be set to auto-calibrate at the start of each print.
If you are using the printer for the first time, you can download the default Simplify3D profile for a specific device by selecting Help > Setup Assistant in the program. After loading the profile, click "Change process settings", go to the "Scripts" tab and select the startup script. This set of commands defines the actions that the 3D printer will perform at the start of each print. nine0005
Source: simplify3d.com
To auto-calibrate the 3D printer, edit the G-code of the script. To do this: at the beginning of the file, you need to add the G29 command, which tells the printer that you need to perform the table auto-calibration process. In this case, the 3D printer must perform a standard homing operation before it starts the alignment process, i.e. the G29 command must be placed after the G28 command (homing command) in the script. nine0005
Startup scenarios may vary depending on the model. There are several different types of G28 commands, such as the regular "G28" (all-axis coordinate origin), "G28 X0 Y0" (X and Y origin only), or "G28 Z0" (Z-axis origin only). For the script to work correctly, the G29 command must come after the most recent G28 command.
Source: simplify3d.com
After making these changes, you must save the new printer settings. To check if the changes were successful, it is enough to start a new print on the 3D printer and make sure that the table auto-calibration process is performed at the beginning of the print. nine0005
The auto-leveling process is mainly controlled by the firmware, so the exact locations where the sensor moves are already predefined on the machine. It remains for the user to add the command indicated above, and the printer will do the rest - it will set up the autolevel of the table.
Total
The auto-calibration process simplifies 3D printing by eliminating the need for time-consuming manual adjustments. A self-calibrating 3D printer guarantees a quality result every time you print.

In addition, experienced technicians can install the auto-calibration sensor themselves. 
This can lead to deformation of the printed model, distortion of dimensions and proportions, clogging of the extruder (when the nozzle is close to the table and the plastic cannot come out). 
Before printing, the 3D printer determines the position of the print bed relative to the extruder and, if necessary, adjusts the position of the nozzle during printing. nine0005 
This, in particular, improves the adhesion of layers and print quality. 
After loading the profile, click "Change process settings", go to the "Scripts" tab and select the startup script. This set of commands defines the actions that the 3D printer will perform at the start of each print. nine0005 
For the script to work correctly, the G29 command must come after the most recent G28 command.
