above I have linked my version of Marlin 2.0

I enabled a 4x4 double probe grid for BLtouch uses following parameters to install BLtouch #define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN

Linear Advanced is now enabled, I have my value set to a K1.0 but feel free to adjust it, because now you can. BigTreeTech disabled linear advanced because it doesn't work with Junction Deviation

I changed junction deviation to Jerk, because Jerk is tried and true. also it plays nice with linear advanced.

Retraction rates are now 3.5mm at 37mm/sec

not much else was changed, this works for me. please follow TeachingTech's github on how to dial in your printer. with my Marlin profile you should be able to change all values that he recommends. i had issues with the firmware provided by bigtreetech with is what prompted me to compile my own version.
