    probably use one for motherboard cooling.
    Everything on top of the BB, will eventually be covered/protected.
    There are a bunch of connectors I have no idea what they do.
    No idea where the z-probe/calibration connector goes.
    Got to be some kind of spec sheet somewhere.

    Any idea what the ones I've circled do ?

    Ah ha- ame thing being sold on amazon.com has abunch of links to data sheets :-)
    https://www.amazon.com/OSOYOO-Contro.../dp/B015SKY19M
    $99 - they're having a laugh !
    :-)

    Looks like i can power the board up with screen attache dwith the usb cable alone.
    That makes life easier.
    Can do that now !
    brb

    Touch screen bright and very responsive.
    But can you spot the immediate problem ?
    Yep it's all in chinese.
    Can't find a language selection option either.
    Picture/buttons are fairly self explanatory - but nothing suggesting language selection.
    Probably have to load up english firmware, recall reading something about that somewhere.
    Other than that - fairly impressed :-)
    I mean, it does work !

    Doesn't appear to read sd card or usb though.
    have to go find that thing I read.

    Osoyoo.com is the dogs bollocks :-)


    Right next job - how do i tell the motherboard It's running a delta ?
    Plus it looks like it's the screen/card reader that restarts the print after a power cut. Nothing to do with the board :-)
    Icon bottom left - the 'continue' button.
    To read from a usb stick you just set it to read from usb not sd.
    Doesn't automatically switch to whichever is plugged in. But seconds to change over.
    Now that is bloody useful !

    So all these super expensive 3d printers that are boasting about power cut continuing. It's a 29 screen that's doing it lol

    Just had a look and can't see anyway of plugging one of these into Alexa's board. Which is a shame, she'd look good in colour lol

    Basically downloaded a file from here: http://osoyoo.com/2016/07/25/mks-tft-2-8-touch-screen/
    Unzxipped to sd card. put sdcard into screen, rebooted screen with reboot button. Automatically updated to english firmware.
    Took a couple of minutes.

    It's got to get more complicated from here.
    Also has auto levelling options. Now that would be cool if it just did it without all that buggering about.

    So, yep you need one of these.
    Also says you can add your own boot up graphics.
    I will be playing with that !

    Repetier host talks to it :-)
    That said I currently have no clue how to get it to change board settings.
    Have to read the manual I guess :-)

    So where does that lurk ? Never managed to find one for alexa.
    Or figure out how to change it, etc

    Anyway suns out, not raining. Going to walk the dogs - that's plenty excitement for one afternoon ;-)

    You're going to have to figure that out. I don't have one to test on. Good luck!

    I have a dollar that says if you can get the configuration file off of the He3d, you'd be able to use it on the MKS.

    the screen firmware has configuration.txt. Changed a bunch of settings, re flashed.
    Doesn't look any different and no ther way if testing. But should do the job.

    Some interesting options.

    just enabled 3d effects - curious to see what that does.
