    Hello

    I have build the mpcnc and want to use it as a laser engraver. The complete hardware build was finished, but now i am stuck at the elektronics (i am an electrician by the way). So the motors don’t move, as i said them through repetier-host.
    They make funny sounds, like a small Alarmhorn
    I have changed the driver, but nothing changed
    I tried a diferent connector on the ramps 1.4
    On the ramps itself is the firmware downloaded from the assembly guide
    The false thermistor is also in its place

    Another problem is that the LCD only shows 2 rows of white squares.
    I hope anybody can help me.

    These things should all be included in your post. It makes it much faster to diagnose problems.

    1) Did you buy everything from here?
    a)If you didn’t or changed some things please don’t leave out any details and include what firmware you flashed.

    2) Are you using end stops?
    a)If so please disconnect them.

    3) Mac or PC?

    4) Include a picture so obvious errors might be spotted.

    Different screen than we use. You need to modify the firmware.
