      Hi,

      today i set up a printer at work with a Duet Wifi, everything seems to work just fine except for the Z-Homing with BLTouch.

      Whenever the Printer reaches Z in Homeall.g OR when i press just "home z", all it does is lift z as i want, move to the coordinates i want to do G30 at, but then it just stops there, the bltouch pin does NOT deploy and the manual bed levelling assistant in the web interface pops up(also pops up when i click bed levelling and wants me to probe every point manually).

      it wants me to manually lower the nozzle etc., i press okay, z axis is homed. HOWEVER it does that every single time i want to home z. I use the exact homez and homeall as i use on my private printer where it works just fine. is there a way to disable the manual bed levelling assistant so i can finally print? (the bltouch deploys and retracts fine via macros btw, so i am quite sure the problem is the assitant)

      thanks in advance.

      ; bed.g
      G28 ; home all axes first
      M557 X5:145 Y5:145 S70 ; Define mesh grid, 35mm spacing between points
      M561 ; Clear height map
      G29 S0 ; run probing and calculate bed compensation

      ; homez.g (SENSOR)
      G91 ; relative positioning
      G1 Z3 F100 S2 ; lift Z 3mm relative to current position
      G90 ; absolute positioning
      G1 X90 Y90 F5000 ; go to first probe point
      G30 ; home Z by probing the bed

        Check the M558 command in your config.g file. It sounds to me that either you don't have one, or you have P0 in it instead of P10.

          @dc42 thanks for your answer, its in mode P9, as i said i am copying my working firmware from at home. its also on firmware 1.19 rather than my one at home which is on 1.21, could that have something to do with it? i will try to put it in mode 10 as you mentioned aswell

            @dc42 after reading a lot in the forum, i think the firmware might be the issue since i am on 1.19 on that printer and m558 p9 seems to work from 1.21 upwards only, will update firmware tomorrow and let you know

              You are right, it should be P9 for BLTouch, and P9 isn't supported in firmware 1.19.
