    Actually I was wrong!
    Did the testing again this evening and everything works! The pinout is correct!
    Now, when I short J1 pin 1 to ground, nozzle led 1 is on, and green leveling led flashes sometimes just for a short while.
    Shorting J1 pin 2 to ground brings on nozzle led 2. If both of them are shorted to the ground, the green leveling light also comes up. I think it's a normal behavior. Can anybody confirm, if printer is doing the leveling with green led on, are the nozzle lights also on?
    Regarding the orange light, it did not work only because it was dead Replaced the led and now shorting J3 to ground brings it on!
    Now it's time to finally wire everything up the correct way.

    Edit:
    Even tested the original optical Z-sensor. It's analog, I was getting readings from 1.6 to 2V on J2 pin 7, depending on the amount of light it was seeing while moving towards the surface. I'm not planning to use it, but good to know.

    LOL I literally do not level my printers as I leveled them once without leveling compensation being active.

    Actually, I still have one tick in Y.

    Cube wiring redefined

    IMG_6184 copy.pngIMG_6185 copy.pngIMG_6187 copy.jpg

    Most of the wires re-used. Thermistors and IR Sensor are connected. Fans are not yet soldered on the pigtails. Leds are only a mock-up

    Testing LEDs and fans, the little pcb board works as expected

    I remember you have re-used the small USB boards on the printer. I for some reason have trouble using the one with USB A connector. +5V and Ground are connected, and data tracks are not. Probably because of the logic elements on the board, dunno. Did yours work right away or you had to do some modifications?

    Yes i used the original cable and connected IT to LCD Display, the USB C is connected to USB C Port in the mobo
    You can weld a connector or weld to Pins... The original Boards are Essentialy USB connectors, try to Swap RX, TX lanes

    Yep, I did that, but for some reason I don't have a connection
    The one with USB Type B connector works, the one with USB type A - does not
    I thought maybe it's because of the small chip on the board, kind of protection?

    Edit:
    Removed the protection chip and shortened the corresponding pins. Now it works. Apparently my protection chip was busted.

    Another Edit:
    Also finally solved some issues with the small white break-out pcb board. Decided to remove the U2 element near J1 connector.
    Now everything works perfectly.

    New challenge:
    In order to light up nozzle leds (I'm using them to light up the print), I need to connect the wire from J1 pin 1 to ground. But on the motherboard there are digital pins that I can control and set to high (+5V). How can I control pinning the led wire to the ground using this digital pins? I'm not an electronics engineer unfortunately, my knowledge here is limited. Unfortunately the power expander board, I'm using for 5V turbine fan, cannot be used in this case. Any other mosfet boards? Any help is much appreciated.

    Challenge edit: solved
    Led is now controlled by the print board, with PWM, I can control the brightness.
