    After that happens the printer makes lines like crazy not following the g code . I use cura but I noticed that it happens in matter control also

    Try directly from an SD card then, I bet you have a USB comm failure occurring.

    You'll have to explain that last one.
    The SD card is directly mounted to the Arduino/RAMPS so there is no communication to fail...
    Write the Sliced gcode file onto the SD card then mount it in the Robo and print from there.

    How you launch the print from the SD card depends on the software you are using.
    I use Simplify3D and this is a screen shot of the machine control panel where you can start/stop/pause an SD card print.
    Whatever software you are using should have a similar way to deal with it. You can simply mount the SD card on a PC and copy the GCode file over that way, that is easier and faster than uploading to it from the program.

    Perhaps someone else who uses MatterControl can tell you how to start a print from the SD card.
    Copying over to the SD card is easy.
    Put it in a card reader on your PC/Mac/Whatever and copy the *.Gcode file over there.
    (I usually give it an 8.3 sized filename -- like MYFILE.GC)

    Then put it back into the card reader on the printer and do whatever your software requires to have the printer start printing from that file.
    If you have an LCD screen installed it will offer that as an option as well.

    I use the SD card and this are the results . The first layers are perfect and then it fails

    You just said you used mattercontrol, that's from cura.

    Measure the thread pitch by counting the number of threads per inch (25.4mm)

    or use a caliper to measure the thread pitch. Count 10 threads and measure the distance if that helps

    18 threads per inch
    .500 if I measure 10 threads

    Your Z steps per mm are correct at 2267.72 then. I'm not totally sure what could have caused the second layer like that.

    Try a 10mm calibration cube and see if it prints to the correct height.
