      I am almost don building my first printer. I have a CoreXY. I am using a Duet WiFi (original), DC42 ir sensor. I have the X and Y moving correctly and finding home.

      no matter if I use the home all or do one axis at a time. I always get the same G28 Error: G0/G1: insufficient axes homed.

      the Y endstop is located at the front left. the x endstop is on the left of the x carriage. the z probe is right by the hotend.

      here is my config file

        @tofuatsu You need to ads a S1 to all axis moves that are done before homing. For example: G1 Z5 S1 F3000

          Please forgive me.. I am really new. I looked into it.. are you talking about adding S1 command in the homeall.g file? I think they are present. This is my file
          ; homeall.g
          ; called to home all axes
          ;

          G91 ; relative positioning
          G1 Z5 F6000 S2 ; lift Z relative to current position
          G1 S1 X-305 Y-305 F1800 ; move quickly to X or Y endstop and stop there (first pass)
          G1 S1 X-305 ; home X axis
          G1 S1 Y-305 ; home Y axis
          G1 X5 Y5 F6000 ; go back a few mm
          G1 S1 X-305 F360 ; move slowly to X axis endstop once more (second pass)
          G1 S1 Y-305 ; then move slowly to Y axis endstop
          G90 ; absolute positioning
          G1 X15 Y15 F6000 ; go to first bed probe point and home Z
          G30 ; home Z by probing the bed

          ; Uncomment the following lines to lift Z after probing
          ;G91 ; relative positioning
          ;G1 S2 Z5 F100 ; lift Z relative to current position
          ;G90 ; absolute positioning

            @tofuatsu I finally got around to upgrading my corexy with the presale DuetWifi from 1.18 to 2.02RC6 and had to change my homing files.

            My homeall.g:

            ; Relative positioning
            G91
            ; Lift Z
            G1 Z5 S1 F9000
            ; Move towards X and Y axis endstops (first pass)
            G1 X-405 F3000 S1
            G1 Y-305 F3000 S1
            ; Go back a few mm
            G1 X5 Y5 F9000
            ; Move slowly to axis endstops once more (second pass)
            G1 X-405 F360 S1
            G1 Y-305 F360 S1
            ; Absolute positioning
            G90
            ; home the Z axis
            G1 X200 Y150 F9000
            G30

                Check that there are no commands in your deployprobe.g and retractprobe.g files, unless you are using a BLTouch - in which case, check that they are the correct commands.
