      The diode is recommended when using Duet WiFi/Ethernet boards earlier than revision 1.04.

        @dc42 Got it.

        I've connected up per the last diagram I posted and the sensor is responsive in all the right ways 🙂

        Now I need to focus on my G-Code to make Home at bed center and set the probe.

        Thanks for all the valuable feedback and support you provide in this forum.
        I'm very grateful.

        Best Regards,

          @dc42 I'm at the point now where I'm testing my gcode for this and found that my TronXY XY-08N inductive z-probe is not working properly with my Duet2 WiFi using my Ultrabase hetbed by AnyCubic.

          With my RAMPS systems this combination works.

          I'm wondering if my cgode could be tuned better.
          Here is my z-probe gcode in the config.g file:
          ; Z-Probe
          M574 Z1 S2
          M558 P5 I1 H5 F100 T36000
          G31 P250 X-32 Y-10 Z-0.5
          M557 X20:200 Y20:200 S40

          As a test, I threw another aluminum bed on top of the AnyCubic hetbed and did a Home Z test and it worked fine, but with the AnyCubic, it seems the ability to sense the metal below is not working with my Duet2 WiFi controller.

          I have tried different T and F settings with M558 and also tried different P settings with G31.

          Any suggestions?

          Best Regards,

            Please run the static test decribed at https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe and tell us the results.

              @dc42 Thanks for your reply.
              My Z-Probe is inductive, so no retraction, etc...

              Here are my results for each test item using my metal bed with 3mm glass on it:

              Z-Probe static test:
              Test item 1: With the Z probe deployed (if applicable) but not close enough to the bed to trigger it, check that the Z probe reading in Duet Web Control is zero or close to zero.
              Response for glass: Probe reads "0"
              Response for Ultrabase: Probe reads "0"

              Test item 2: If your Z probe is of a type that produces a continuous output when triggered (for example IR, inductive, capacitive and switch-type probes), hold a surface below the Z probe to cause it to trigger (or jog the nozzle towards the bed until it is close enough to trigger). Check that the Z probe reading in DWC is correct (about 537 for the Mini Differential IR probe, and about 1000 for most other types).
              Response for glass: My probe reads "1000"
              Response for Ultrabase: My Probe reads "0"

              PanelDue test sending G31: Results read same as above.
              I also sent M119 and read TRIGGERED for glass and OPEN for Ultrabase.

              Z-Probe dynamic test:
              Test item HomeAll: X and Y trigger correctly for both bed types.
              Response for glass: Probe reads "1000"
              Response for Ultrabase: Probe reads "0"

              Z-Probe calibration trigger height:
              Here is my final - working - Z-Probe configuration that works with my 3mm glass bed:
              ; Z-Probe
              M574 Z1 S2
              M558 P5 I1 H1 F100 T36000
              G31 P250 X-32 Y-10 Z1.0
              M557 X20:200 Y20:200 S40

              The settings above work perfectly with the glass bed.
              Using these settings with the Ultrabase, the Z-Probe never triggers using the Duet2 WiFi, but it does when I replace the controller with my RAMPS1.6.

              My question / concern is not if the Z-Probe works with the Duet2 WiFi, I have proven that is does work with my glass bed.
              I am trying to find the right g-code solution to have my Z-Probe work with the Ultrabase as it did using the RAMPS boards and Marlin F/W.
              As previously mentioned, I have tried various g-code settings for:
              M558 F and T, as well as for
              G31 Z

              Best Regards,

                Does your probe have a LED that lights up when it is triggered? If so, does it light up when you trigger it with the glass bed? What about with the Ultrabase bed?

                  @dc42 Yup, it has the red light. M119 also registers TRIGGERED coincidentally when the red light is on 🙂

                  With my glass bed, the lights are on and everyone's home.
                  With the Ultrabase, the lights are off and nobody's home.

                  In my opinion, I'm seeing the Ultrabase must be blocking out enough of the return signal to have it not register. So either a timing issue (maybe a gcode setting) or power level to the sensor.

                  It's not the end of the world as I actually like my glass bed more than the Ultrabase because glass is easy to clean without accetone, but I'm researching hotbeds for a new printer and really just perplexed why this combination works with RAMPS, but not Duet.

                    I am perplexed too. As I said before, the only difference reason I can think of why the trigger height would differ is if the supply voltage is different.

                      @dc42 Sorry for the delayed response. My son was married over the weekend.
                      My thoughts are the same as yours. Is How would I test the output voltage of the Duet2 WiFi for this specific setup?

                        @dennishall what did the correct wiring for your blue tronxy sensor turn out to be?
