X Axis Step Motor doesn't move

[msmeeh]

Hello,

i just bough the Geeetech i3 x dual extruader printer, after the assembling i went to try it the step motor is just vibrating in his place and doesn't move i removed the strap and everything to make the motor move freely and it is still vibrating in his place.

everything is working fine except the X axis motor , after i tried to adjust the vault base on subject in this forum to low the voltage the motor is in the same condition nothing change and after more tries to change the voltage the LCD start to showing black squares i tried to return the voltage to the same situation before but no success the LCD no longer working only black squares.

i removed the USB and it is the same black squares.

please give me solution or replace your damaged parts.

what's the driver voltage? is it proper? And if the voltage is correct, this might be a bad motor or motor cable or driver itself. You can switch any of them with the other working ones, see which one of them is dead. You can also check out this link here:
