I do not use a color LCD and I do all of my mesh maintenance through the terminal.
Here is the gcode I use to create and store a mesh:
G28 ; home all axes
M420 S0 ; Turning off bed leveling while probing
M155 S30 ; reduce temperature reporting rate to reduce output pollution
M190 S85 ; wait for the bed to get up to temperature
G29 P1 ; automatically populate mesh with all reachable points
G29 P3 ; infer the rest of the mesh values
G29 P3 ; infer the rest of the mesh values again
@BEDLEVELVISUALIZER ; tell the plugin to watch for reported mesh
M420 S1 V ; enabled leveling and report the new mesh
G29 S1 ; Save UBL mesh points to slot 1 (EEPROM).
G29 F 10.0 ; Set Fade Height for correction at 10.0 mm.
G29 A ; Activate the UBL System.
M500 ; save the current setup to EEPROM
M155 S3 ; reset temperature reporting
M140 S0 ; cooling down the bed
Note that the slots are arbitrary. If I used filaments that required significantly different bed temps I would create a different mesh per temp.
I then recall that slot (S1 in my case) via start gcode and also perform a 3x3 tilting correction with the code below:
; This gcode has been hacked together by Jason to incorporate ABL
M73 P0 ; clear GLCD progress bar
M75 ; start GLCD timer
G90 ; absolute positioning
M82 ; set extruder to absolute mode
G92 E0 ; set extruder position to 0
M140 S{bed_temperature[0]} ; start bed heating up
M190 R{bed_temperature[0]} ; wait for bed to get to temp
M104 S160; start warming extruder to 160
G28 ; Home all axis
G29 A ; enable ABL
G29 L1 ; Load saved mesh from bank 1
G29 J3 ; 3x3 point tilt mesh
M109 R{first_layer_temperature[0]} ; wait for extruder to reach printing temp
M117 TAZ 6 Printing… ; progress indicator message on LCD
; END_START_GCODE
Let me know if this helps stitch things together for your printer.
