It is about several months I'm involved setting up bed leveling for my delta printer
It level the bed,I store settings but when I start printing the result is awful one side sticks to the bed other side no
I tried different version of marlin but It not fixed,I can't use my printer
I use micro switch as probe
my hardwares are skr pro V1.2 and tmc2130 V3.0

I always use babystepping to fine tune the first layer during the skirt phase. I set my skirt lines to at least 6 so that I have time to play with the babystepping.

Personally, I use UBL bed leveling rather than bilinear just because I can use the G29 tools to edit the mesh points and the G26 command to see where the mesh needs to be adjusted.

On older version of marlin firmware you have to manually enable bed leveling data using startup G-Code in slicer this is place in after the last G92

thanks for your reply
I tried ubl bed leveling but still first layer is awful
what I understood is that because I use sensorless homing some times the print hight changes between 0 and 0.5 mm
maybe it cause the issue!

Then enable babystepping and Probe offsets.

In Configuration_adv.h enable "#define BABYSTEPPING:
Additionally you could enable "#define BABYSTEP_ZPROBE_OFFSET"

Used babystepping for quite some time while printing a skirt around you will have enough time using the LCD control to nudge nozzle into the perfect height.
Using the Z_Probe offset you can adjust nozzle offset before print start, this is in newer version of Marlin 2.x.x my 1st choice.
