Why does bed leveling does not fix this?  

RE: Why does bed leveling does not fix this?

I check in the menu and it's 3x3.

I just setup it to 7x7 and will run the print again.

To be honest I was thinking the bed leveling on prusa is so long... 😆 imagine the 7x7!

let's see!

RE: Why does bed leveling does not fix this?

7x7 takes ~1min12sec of leveling, ~1min20sec before start printing the part
3x3 takes ~8sec of leveling, ~18sec before start printing the part
you can see that the 7x7 fix the problem. But the B corner looks better on the 3x3
the 7x7 is overall very consistent.

thank you Neophyl
Imagine if we could select in the slicer if we want to use 3x3 or 7x7! I check github if anyone ask for that feature but did not find it.

RE: Why does bed leveling does not fix this?

I cant remember what the format is but iirc you can set it in the printers start gcode block.  Also be aware that the pinda operation is still temperature dependent, you can get different results depending on if the printer is 'cold' or warm, ie has been printing recently. 
Thats why I always calibrate the live z at a set known working temperature and also spend some minutes preheating before printing to get to the same temp.

3D printing is not a quick process.  Worrying about a few minutes difference is not worth it.  Id rather I ALWAYS get a great first layer than save a minutes time.

Found what I was thinking of
https://help.prusa3d.com/article/prusa-specific-g-codes_112173

G80 with all the parameters 

For example
Usage
G80 [ N | R | V | L | R | F | B ]

Parameters
N- Number of mesh points on x axis. Default is 3. Valid values are 3 and 7.
R- Probe retries. Default 3 max. 10

RE: Why does bed leveling does not fix this?

thanks for the info. I iterate a lot with my prusa, I want speed. I am at 0.6mm nozzle and print 0.4-0.5mm height. It's rare that I want 0.2mm layer height quality. But today is that day! 😋 I have 1024d and 4859m on my printer since Jan 2021.... wait that is 785 days ago...🤔

Anyway, I was able to find the command and does work great! I appreciate your help.
You remove the N7 for 3x3

G80 N7 ; perform 7x7 bed mesh leveling
