Did you generate the gcode file? the SD card can only reads gcode files and the format is FAT or FAT32, if all those not work, then I think you should find another SD card to try it.
And z axis can not move, then how about refer to the link here:http://www.geeetech.com/forum/viewtopic ... 13&t=17038
