      Hi all,

      I'm having issues getting the 3dtouch probe to do anything on my new printer (https://forum.duet3d.com/topic/15550/3davii?_=1592476055256).

      The symptoms:
      When starting the printer the 3DTouch does it's usual startup routine (down,up,down,up). After which it settles in the up position with the red light continuously on (if I remember correctly that is what is supposed to happen). So all seems well, however as soon as I try to deploy the probe in any for nothing happens. I do not get a Duet error nor does the probe go into the blinking alarm state.

      One other weird thing I noticed is that when the duet starts it tells me in the webinterface that the probe is measuring -1000, however the whole probe indicator dissapears from the web interface within a matter of seconds.

      Any help would be greatly appreciated. If any additional information is needed please let me know.

      I am using a duetwifi2 and duex 2 with RRF3 and the new web gui

      The 3DTouch I am using: https://nl.aliexpress.com/item/32958675206.html?src=google&src=google&albch=shopping&acnt=494-037-6276&isdl=y&slnk=&plac=&mtctp=&albbt=Gploogle_7_shopping&aff_atform=google&aff_short_key=UneMJZVf&&albagn=888888&albcp=6459980570&albag=76980386066&trgt=743612850714&crea=nl32958675206&netw=u&device=c&albpg=743612850714&albpd=nl32958675206&gclid=Cj0KCQjwoaz3BRDnARIsAF1RfLeL6LJvrGyyVg08edGCaS-twLaIrZcKKIKt-2n2DzhLqUQ6YRUGQsUaAn5jEALw_wcB&gclsrc=aw.ds

      Connections:
      The 3dTouch sensor part is connected to the duetwifi zbed sensor connector, the actuator side is connected to the Duex2 PWM5.

      Configuration (as generated by reprap configurator):
      ; Z-Probe
      M307 H7 A-1 C-1 D-1 ; disable heater on PWM channel for BLTouch
      M558 P9 H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds
      G31 P500 X0 Y0 Z2.5 ; set Z probe trigger value, offset and trigger height
      M557 X20:200 Y20:200 S40 ; define mesh grid

      Deploy Probe script:
      M280 P7 S10 ; deploy BLTouch

      Retract Probe script:
      M280 P7 S90 ; retract BLTouch

        RRF3

        If you are using RRF3 your config is incorrect.

        Please send M115 to verify your installed firmware version and send M98 Pconfig.g and report back with any error messages you get.

        If you are using RRF 3.1.1 you'll need to modify your config to match. It will likely be easiest to use the web configurator to generate a new config compatible with RRF3.

          Erm. Yeah you're right no idea how I missed that... I fixed that right away. However it still does not work. Tomorrow I'll double check everything and report back!

          The M98 is handy thnx did not know that existed.

          The config for Bedlevel is now:

          M557 X15:215 Y15:195 S20 ; define mesh grid

          The M98 reported, heater warnings are as expected since I have not configured my tools yet:

              @Phaedrux updated a quick test still gets me the same result. I'll double check everything later today.

              Edit: the Z probe now shows in the web interface though 🙂
              Edit2: I found a M307 for Heater 7 (PWM 5) in the config-override.g, however I do remember reading the Duet holding on to old config. How do I make sure the duet forgets about the old config?

                Please post your current config.g, config-override.g, deployprobe.g, retractprobe.g, and homeall.g/homez.g

                Are you still plugging into the Duex? Which port again?

                  @Phaedrux Hi Phaedrux, thnx for your time as always.

                  Yes I am using the Duex2 port pmw5. I have only included the homez.g, homeall.g is not right. Do keep in mind that I am not homing I'm just trying to get the probe itself to move. Onze that works the rest should not be a problem.

                    @Phaedrux I was checking the documentation and noticed that the duex2 under version 0.8b does not support PWM 4 and 5. How do I check which version the board is?

                    Edit: Just checked and it is version 0.8. I'll move it to PWM3 later today.

                      @Phaedrux Alright so I am doing something seriously wrong. It is not behaving as I expect.

                      I've moved the connector to Duex PWM3 and changed the config. When I start the printer the Touch goes into error blue on blinking red.

                      When I then plug the Touch back into PWM5 and start the printer it does the correct startup procedure even though the config is pointing to PWM3.

                      config.g:
                      ; Z-Probe
                      M950 S0 C"duex.pwm3" ; create servo pin 0 for BLTouch
                      M558 P9 C"^zprobe.in" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds
                      G31 P500 X0 Y0 Z2.5 ; set Z probe trigger value, offset and trigger height
                      M557 X15:215 Y15:195 S20 ; define mesh grid

                      config-overide.g not changed.

                      Deploy and retract changed P7 to P5

                        When using the Duex you must remove the I1 from those commands.
                        And when using RRF3 you must change the P number to match the index of the servo pin you created, so M950 S0 C"duex.pwm3" is servo #0, so your deploy and retract should be

                        Deployprobe.g:
                        M280 P0 S10

                        M280 P0 S90

                        Your home Z is using an endstop move, you'l need to change that to use G30 to use the probe.

                          Ah Yeah. Saw it in the documentation. I just assumed that hadn't changed for RRF3. Thnx

                          @HomeZ, yeah that is by design. I have 3 independent Z axis drivers and first home it to the end stop to make sure it's straight after which I'll fine tune using the bed level sensor.

                            @Phaedrux Hi, I've resolved it. It turns out one of the wires on the connector wasn't making a connection 😧

                            Sorry for wasting your time and thnx for your help and patience! 👍

                            Edit: So I tried going back to PWM5 since that's the one I would like to use and that is indeed not working. (well only on startup for some reason). Not a big issue thouh. However I would've liked to have the bed level sensor plugged into the most left PWM.
