I too have been having this problem with the lack of 'squish' as Chep calls it!
I bought a BL Touch to help me with my bed levelling, not to hinder it. Yes it is an official BL Touch as well as my Maestro.
Started at 6am and had all the cabling wired and tested probe it would fire.
All good. fitted it and by luck it was it was 8mm above the nozzle tip. Thanks Phaedrux, but did not find this post until 15:00.
After following the info in here and all of the other good links, i was still getting nowhere, still no squish.
I thought, back to basics.
Wound all 4 bed level nuts tight and then backed of by a turn.
Did the Z adjustment with a piece of paper in the centre of my bed.
Reset Z to 0
Homed all of my axis again. Jogged Z up 5, piece of paper under nozzle and jogged Z until it hit its max. Paper felt good.
Disabled X and Y steppers and must of gone round the bed about 9 + times with the paper until it all felt good, adjusting the corners as i went.
Did the suggestion @Phaedrux suggested, removing the M98's
Then pressed the Auto Bed Compesation. All was shades of green when it had finished. Result.
Skirt went down nicely and the mount I am printing is looking good also.
There are other tweaks that need to be done, but am struggling to find a definitive guide on settings for Creality Printers.
I am running a Creality Ender 3 Pro, if anyone wants my config as a base please let me know.
