      You just need to choose a point close to the lead screw but still on the bed and both need to be in line on the Y axis.

        @Phaedrux said in Not Homing correctly At all. and nozzle issues:

        G28 ; home M401 ; deploy Z probe (omit if using bltouch) G30 P0 X20 Y100 Z-99999 ; probe near a leadscrew, half way along Y axis G30 P1 X180 Y100 Z-99999 S2 ; probe near a leadscrew and calibrate 2 motors M402 ; retract probe (omit if using bltouch)

        THANK YOU. it worked and I found my correct bed coordinate points. do I have to change any config for my BLtouch current settings are

        Z-Probe
        M558 P9 H2 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds
        G31 P500 X0 Y0 Z2 ; set Z probe trigger value, offset and trigger height
        M557 X5:350 Y5:350 S50 ; define mesh grid
        I have version 3

          The dive height is a little low. It should be at least a mm more than the trigger height. Try M558 H3

          Also change G31 P500 to G31 P25

          Have you calibrated our probe and measured the offsets yet?

            I don't know if i have to enable some settings to run hight map while it prints maybe from slicer or from DWC. thank you for all your help

                  Print a test file like this one with mesh enabled and again disabled. You should be able to tell if it's being applied correctly.

                        G31 P25 X0 Y0 Z1.758

                        You need to measure your X and Y probe offset otherwise the corrections will be off in X Y position.

                        https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe?revisionid=HEAD#Section_Measuring_Probe_X_Y_Offset

                        The heightmap itself looks ok. After measuring the offset redo the G29 and reprint the test file to see if it's behaving better.

                          Thank you for the additional information so my x offset is 44mm and the y offset is -5mm but when I try to run mesh compensation its starting from 44 to 285 and my actual build volume is 350 x 350 so please correct me on that one am I loosing that left over space since it only probing from 44 to 285. Also when I checked my old configuration from the original bord it says offest x0 y0 z1.78 so I don't if that does matter or not. Please let me know thank you
