      Help Please. I have run the G29 S0 command in the past month, but I had to readjust my bed, so I needed to run it again. When I run the command, no matter what height the nozzle is as it heads towards the first point, it is lowering itself down to zero, which makes the BLTouch I am using not trigger because it is too low.
      I thought before if I set the height to 10mm and start it would deploy the Probe then approach th first point then Z axis would lower until the BLTouch triggers. I do a G28 to start this off, then raise to 10mm.
      I have attached my config.g file. I am copying the m558 and G31 commands I have been changing to see if it makes a difference.
      M558 K0 P9 C"io4.in" H0 F120 T6000
      G31 P500 X43 Y21 Z2.5; set Z probe trigger value, offset and trigger height
      M950 S0 C"io4.out" ; create servo #0 for BLtouch

      Forgot to Mention I am using the Duet 3 Mainboard 6HC with SBC Pi 4

        @darylprice said in G29 Not working correctly:

        M558 K0 P9 C"io4,in" H0 F120 T6000

        Your dive height is null (the H parameter in bold above). You may want to try the command below where the probe will attempt to probe from Z7.5 (10mm from the M558 command minus the 2,5mm from the probe offset)

        M558 K0 P9 C"io4.in" H10 F120 T6000
