@sgk there doesn't appear to be anything wrong with your config.
Can you confirm that the stepper motor attached to driver 3 is the one thats X-45 Y165 and that the other stepper motor connected to driver 4 is the one on the other side? -
@jay_s_uk
they are connected as in the photo though
-
@sgk is the left one the one closest to X0?
-
@jay_s_uk excuse me I don't understand questions?
-
@sgk well when the tool is at X0, is it nearest the motor called "left z stepper" or is it closest to the one called "right z stepper"?
-
@jay_s_uk to the left
-
@sgk which indicates that the firmware setup is correct then and its left to either be a mechanical issue, e.g. x axis twist or maybe the IR probe doesn't like being so close to the edge of the bed

-
@jay_s_uk
the impression that I have is that each time I do g32 the bed does not get level and it always goes down more and more on the side -
@jay_s_uk I could make a video to better understand
-
@sgk which is why i think you have the stepper motors the wrong way round
-
@jay_s_uk but when I do home all the 2 z motors go well together they are synchronized
-
@sgk if you have them mapped the wrong way round, RRF will adjust the wrong one
-
@jay_s_uk I could solve this problem how do you have an idea please
-
@sgk change your z mapping in M584 from Z3:4 to Z4:3

@jay_s_uk
ha ok i will try now thank -
@jay_s_uk I have this as an error
Error: Z probe readings not consistent -
