    I have never tried to connect to the printer directly with anything other than OctoPrint. I am not really clear on what you gain by doing it any other way since even if you jacked a USB cable into the printer you are still connecting to the RaspberryPi and not the printer control board.

    As for updating the firmware -- the LCD will do all of that for you.

    Is there something specific you are needing to do differently?

    Thanks mark for the rapid response ..
    Perhaps you can explain to me better, what's the correct workflow to print .. with out the usb drive ..
    And doing it by the network ..
    Thanks !!

    The RaspberryPi is a computer and has WiFi built in so use the LCD to configure it and get it connected onto your network. The printer has one of these inside it already.

    From the LCD go to Utilities->Network->Configure WiFi

    Do what is needed to get it connected to your Wifi network.

    Once it is connected to your network get the IP address (let's imagine it is 192.168.0.123) then connect to the printer with a web browser
    (http://192.168.0.123/) and you will be connected to OctoPrint running on the Raspberry Pi inside the printer.

    Utilities->Network->Network Status will report the IP address to you so you know how to figure that out.

    Once connected to OctoPrint you can upload the models and slice and print them on the printer or slice them (turn them from STL files into GCode) in a slicer on a different machine and then upload the GCode to the printer and let OctoPrint do the printing.

    I'm doing it by ethernet ..
    Not WiFi allowed .. and i'm connected to Octoprint as well ..
    I was curious/Trying to undestand cura .. wich as far i understand, from it just can send the files, but not manipulate the printer ..
    just from the web browser .. correct ?

    If you use Cura (or any other slicer on a PC) you need to upload the sliced GCode to OctoPrint before you can print with it.

    Regardless of WiFi or Ethernet -- however you connect to OctoPrint that is what you are using to start/stop the printing. You can use any slicer to slice the models and then just upload the GCode

    If you click print it should load and print. It is actually stored on the Pi SD card. It should show up in the list of loaded models to print I would imagine. I seldom (OK, never) slice with OctoPrint though so I would need to go experiment.

    So I uploaded an STL to OctoPrint it then prompted me to slice it, I picked a profile and sliced it.
    It then added it to the top of the list of FILES (left hand side of OctoPrint screen is the files list) and I could print it.
