because baby step didn't work
Were you trying to babystep up or down? If down it would be limited by the height of the first layer. You can change the M208 minima for Z to be slightly negative to give it more room to go down. M208 S1 Z-1 for example. Might be helpful while getting things tuned in but will increase your chances of a nozzle crash if not careful.
The bowl shape would match with most Ender beds. And the tilt would appear to have been mostly corrected. Seems like an improvement?
Are you now using the BLTouch settings I posted above?
I have been using your recommended settings now, maybe better results, more reliability. Well, I'm with ender 3 pro, which has standard aluminum build plate with flexible removable surface. I swapped it with an ender glass surface. I have tried flipping it, same results (bowl effect). Also I have "glass fiber" creality surface, which is the same material in electronic boards. Bed mesh is completely different, it doesn't have bowl effect, just some twist, because it is a little bit flexible.
Funny, but I still keep getting weird results. Printing for example same 5x5cm part in the center of the bed. On the left side lines look perfect, and 4cm to the right - lines not being connected. This was printed in TPU. With PLA it gives much better results, almost perfect. I guess TPU is less forgiving, when laying down first layer. But still problem persists with TPU.
Obviously bed compensation works, just not sure if enough. Might be problem with backlash? Ordered an anti-backlash nut.
