• Goodmorning everyone

    English translated by google

    I'm a newcomer to 3D printing, long ago I bought the duet wifi card, I took the wiring diagram from the internet to connect everything and so far everything ok, except for a very important fact, the design I downloaded was not correct or better was for the version before mine, when I realized it was too late, I thought I had fried the ir sensor, because 'I reversed the wiring of the same, so I'm not able' to make the ir.
    At this point thinking of having fried the sensor I bought another one, I arrived today and I mounted it "having downloaded the right diagram" respecting the polarities of the board and the sensor, but it does not work, I'll explain better what it does:
    Once the printer is switched on, everything switches on including voltage control LEDs
     +3.3, +5 and Vin, the endsop on X and Y pure and work, after 4 seconds from the ignition the ir sensor led does not turn on and it's strange, then check with a tester if there are 3.3v on the connector and with my surprise there are not, I fucked the 3.3v on the connector? mha we'll see .. in the meantime I always try with other connectors with 3.3v and the voltage on other connectors exists, well I connect the 3.3v to the sensor and the OUT to the connector of the PROBE Z but flashes twice when I expect it to flash 4 times to tell me that it is in analog mode, I wanted to do a little more detailed checks and I found that if I do not connect the sensor OUT to the PROBE Z at the power on, this flashes 4 times but if I connect the OUT flashes 2 times, now I wonder "I fucked the card?" is there a way to make it work?

    If you have the Z probe mode incorrectly configured in he M558 command (e.g. P5 or P8 instead of P1), then the IR sensor may start up in digital mode and flash twice instead of 4 times.

    I've never heard of the +3.3V supply on the Z probe connector failing before. Please check the soldering on the Z probe connector pins, on the underside of the board.

  • I misunderstood myself, I forgive ... the PRobe Z connector next to the PANEL DUE
    gives me 0.98v even now gives me 0v, however, the other connectors are fine and do not give problems, and 'just this connector that does not go connecting (vcc - gnd and in the z probe does not turn on the sensor, but if I remove the wire that carries the signal from the probe to the connector and turn on the sensor works.
    As far as weldings are concerned, they are all ok, and it was the first thing I did
    I am attaching the configuration

  • Good evening everyone

    I solved the problem, all my fault, fortunately, everything works and the sensor even now gives me reading, but do not ratique to get the z-axis home moves up as it should then right and then stops instead of going down and looking 0, the other 2 axes work correctly.

    I would like to thank DC42 for the speedy response
