Mistake True bed levelling G32
-
hello friends after installing my duet 3 6hc card I have a size problem every time I do G32 the bed goes down each time on the left side and it is not level while it shows me that yes like we see it on this command after the g32.
Leadscrew adjustments made: -1.495 1.607, points used 2, (mean, deviation) before (0.136, 1.213) after (-0.000, 0.000).
anyone have an idea please.

@sgk post your current config and your bed.g file.
Also, some info about where your probe is etc -

@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
