      HELLO
      I hope someone can help. Me 😫 I have just setup my bltouch and have done everthing in this tutorial https://betrue3d.dk/bltouch-on-duet-wifi-configuratio-and-usage/#testandcalibrate my problem is that all works as in macros but the G30 S-1 command does nothing :/. I have to use the deploy macro and lower the z-axis instead but then once i set the G92 Z0 the pin stay's retracted with the bltouch red led flashing 😞 then i have to use the alarm + drop pin macro to release the pin homez.g homeall.g config-override.g config.g thank you for any help

        That tutorial is out of date. Use https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_BLTouch

          there are a lot of errors in your config.

          M574 Z0

          this disable z endstops as well as probes

          M307 H7 A-1 C-1 D-1
          M307 H3 A-1 C-1 D-1 ; Disable heater on PWM channel for BLTouch

          which on is it?

          M558 P5 H3 F500 T4000 X0 Y0 Z1 ; Set Z probe type to switch and the dive height + speeds

          P5 is not for bltouch

          G31 P500 X0 Y0 Z1.150 ; Set Z probe trigger value, offset and trigger height

          your offset is wrong

          M305 P0 T100000 B4138 R4700 ; Set thermistor + ADC parameters for heater 0
          M305 P1 T100000 B4138 R4700 ; Set thermistor + ADC parameters for heater 1
          M305 P1 X200

          double configuration and P1 is configured twice.

          you homing scripts do not contain G30 commands.

          i would strongly suggest that you use the configurator to create a new config

              G31 P500 X0 Y0 Z1.5

              Change P500 to P25

              You still need the X and Y offset.

                  M566 X1500 Y1500 Z1000 E200 ; set maximum instantaneous speed changes (mm/min)
                  M203 X2000 Y2000 Z375 E800 ; set maximum speeds (mm/min)
                  M201 X4000 Y4000 Z150 E800 ; set accelerations (mm/s^2)
                  M906 X900 Y900 Z900 E900 I30 ; set motor currents (mA) and motor idle factor in per cent

                  The Z jerk value is a bit high perhaps. And the max speed and acceleration a bit low.

                  Try M556 Z300, M203 Z600, M201 Z300

                  For motor currents target 70% to 85% of the rated max for the motor.

                  M307 H7 A-1 C-1 D-1 ;disable heater 7 to free up for servo signal for BLTouch
                  M307 H3 A-1 C-1 D-1 ; disable heater on PWM channel for BLTouch

                  You still have two heater pins unbound. If you're using Pin 3 for the BLtouch remove the H7, or vice versa.

                  M305 P1 T100000 B4138 R4700 ; Set thermistor + ADC parameters for heater 1
                  M305 P1 X200

                  You still have two different things configured for heater P1. A thermistor and PT100. Which are you using?

                      In that case, delete M307 H7 A-1 C-1 D-1 ;disable heater 7 to free up for servo signal for BLTouch and M305 P1 T100000 B4138 R4700 ; Set thermistor + ADC parameters for heater 1

                              But does it deploy, retract, and trigger as expected?

                                yes 😁 all macros work so i take it the red flashing light is normal:/ because when i move the z-axis up and home z again the probe stays retracted and moves up instead. πŸ€”

                                  Not sure what this means exactly.

                                  Is the BLTouch flashing red or just lit at all times?

                                      Flashing would indicate error state. At what point does it error?

                                          But it stops movement as it should?

                                            @Phaedrux i just tried to upload a video but files to big πŸ˜“and yup it stops but I can't use home z again until I click on the alarm release and drop pin macro πŸ€” because it will just keep moving up on every press
