      Very low or no extrusion in one corner of the print, It was printing well, after ~30 layers, the extruder not extruding one corner of the print, the motor making rumbling noise and not filament getting extruded (Only in that portion), once crosses that length, extruder is acting normal,

      I've checked different files and slicers, but same issue, now from the beginning , the right side corner not getting extruded for every print

      don't know what could be the issue, need help

          do you have a bowden setup?
          it could be that in that corner the filament is path is constricted.

            You should add the information that you had a problem with x axis some days before: https://forum.duet3d.com/topic/12526/x-axis-leaning-need-help
            Maybe the problems are related.

              X Axis leaning issue got solved after correcting the T parameter as suggested, after that , Print came perfect,

              Extruder motor making rattling noise in that corner / some portions alone, filament intake is not happening in that time , after that moment the motor starts working as normal until reaches that region again

                  I'm getting the below warning message
                  Warning: motor phase B may be disconnected reported by driver(s) 3

                    @Milan Maybe X motor became too warm (weakest of the 3 motors) and is damaged. Neodym looses magnetism when more than 80 °C.

                      @Milan If you configuration of the other thread is your current configuration, the current settings for the drivers is very low (only 800 mA in M906), so maybe your stepper is still intact and only too weak for X, firmware thinking you're finished in X and stopping extruding.

                        The motors at normal temp, that rattling happening only in that region alone

                          should I try increasing the current 800mA to 1000mA -1200mA, hope that helps

                            @Milan Your stepper should have a specification about current, then set according to https://duet3d.dozuki.com/Wiki/Choosing_and_connecting_stepper_motors#Section_Rated_current
                            But check first whether the external drivers support the high current also.
                            Nema 23 and Nema 34 have typically between 2.5 and 7 A current, but on the datasheet the correct current should be mentioned.

                              Hi,

                              One or more of the wires to the stepper may be poorly connected and movement into that area causes the connection to be intermittent.

                                  @Milan Can you please send an image of the printer in complete view (there may be printer type specific reasons like for a Delta) and your current config file?

                                    @Milan And one more idea: exchanging the driver/stepper between X and Y would show:

                                    • if nothing changes, problem is with extruder, or filament stuck
                                    • if problem moves to a different corner, the problem is with the X stepper/driver/configuration

                                      Wow, wiring issue, one of the wire poorly connected..@fcwilt was right
                                      now working well

                                      Thanks a ton @JoergS5 JoergS5 and @fcwilt Fcwilt
