    Hi
    I Have Anet A8 (skynet 1.1 firmware)
    Everything works well for a while, I even printed a few things.
    But now the printer gets stuck or just goes crazy after auto leveling is finish.
    I took a video of the problem.
    Video link:


    many thanks

    Well that LCD is scrambled. That usually is the LCD connected wrong, but if it started out working then it is either the LCD or the control board (RAMPS on the Robo -- not sure what electronics the Anet A8 uses, but probably not a RAMPS board). You may need to replace the control board. I imagine you could swap over to generic electronics:
    Google suggests:

    Hi
    Thanks for your reply.
    But I don't think it's a screen problem.
    When I turn on the printer everything is fine including the led screen
    But when I do the auto leveling, at the end of the auto leveling, the printer is freeze .
    Sometimes there is a display on screen and sometimes the Z motor or the X motor keep
    moving without stopping but in all cases the printer no longer responds.
    Thanks again
    Roei

    nevermind, fixed it by using the right bedleveling gcodes. In my case (marlin firmware):

    M140 S60 ; starting by heating the bed for nominal mesh accuracy
    M117 Homing all axes ; send message to printer display
    G28 ; home all axes
    M420 S0 ; Turning off bed leveling while probing, if firmware is set
    ; to restore after G28
    M117 Heating the bed ; send message to printer display
    M190 S60 ; waiting until the bed is fully warmed up
    M300 S1000 P500 ; chirp to indicate bed mesh levels is initializing
    M117 Creating the bed mesh levels ; send message to printer display
    M155 S30 ; reduce temperature reporting rate to reduce output pollution
    @BEDLEVELVISUALIZER ; tell the plugin to watch for reported mesh
    G29 T ; run bilinear probing
    M155 S3 ; reset temperature reporting
    M140 S0 ; cooling down the bed
    M500 ; store mesh in EEPROM
    M300 S440 P200 ; make calibration completed tones
    M300 S660 P250
    M300 S880 P300
    M117 Bed mesh levels completed ; send message to printer display
