DUET 2 WiFi FSR no workie - config?



  • My FSR trinket isn't talking to the DUET2 WiFi.
    JohnSL board and FSRs all signal properly;using my finger lightly on the build plate the trinket red LEDs light up correctly/individually/averaged depending on pressure location.
    Should I see anything blinking on the DUET board, or see the Z-probe GUI change?
    Z-probe GUI always reads 0

    Wiring to the Z-probe connector is correct according to DUET Z-probe wiring diagram.
    Using the OEM GreenBlackRed assignments for the JohnSL
    FSR board is wired to Duet z-probe as:

    0_1558403338606_DUET_zProbe.jpg

    I've tried running g30 and tapping the deck, and switching the wiring between GND and IN. Red wire has remained 3.3v(?)
    The JohnSL trinket lights up as it should, hotspots/averaged, but that signal doesn't halt the g30 as it should so I shut the thing down and try again.
    Ran g32
    effector tracked down to bed,
    moved to Z periphery,
    slowly lowered to trigger FSR - FSR showed contact(lit up)
    crashed build plate until I emergency aborted(but not before the effector was tweaking arms and effector plate joints ...)
    FSRs just aren't talking to DUET.
    nothing registers in GUI; shouldn't I be seeing a response here(Z-probe) when manually/other triggering the FSRs?:

    Not sure what else to do

    I'm thinking there's some config like M581: Configure external trigger or M585: Probe Tool (?) that I need to mess with to have the Z-probe get initialized?

    What does this do?

    Strange, your first photo looked correct to me.



  • Yes, the wiring diagrams I saw clearly are the first layout.
    Then I found one that had some color-blindness going on,
    but got me there:

    It states:
    Grey is the Signal, red is 3v3 and black is ground
    (this is not my board/trinket)
    0_1558668478691_b0bf4eb0-77e7-46aa-ad14-09c70c4b487b-image.png

    I was convinced 'gray'(my red) is 3.3v, because the board was getting power and working/sensing/lighting up the correct LEDs.
    Right?
    I just stared at my config and thought,"what could possibly go wrong? I might fry a $7 (USD) part, but ...
    MAGIC COULD HAPPEN"
    I mean,
    SCIENCE COULD HAPPEN!
    🤔 🙏 🙃

    and there was much rejoicing



  • Nurbie , I'm having similar problems .
    Your solved photo shows the connections at the duet end.

    What are your connections at the FSR end ?

    Is red wire connected to signal on fsr board and at Duet end to Z Probe In ?

    My confusion stems from this paragraph in the duet dozuki:

    If using JohnSL's trinket board: Connect its Vcc, Output and Ground pins to 3.3V, IN and GND on the Z-probe connector respectively and select mode 5.

    John's board does not have Vcc , Output or Ground labels on the 3 pins in the corner of the board.
    They are labelled: Signal , -/+ , +/-


 

Looks like your connection to Duet3D was lost, please wait while we try to reconnect.
