    Anet A8 Z-axis stepper problem

    I just finished building my Anet A8 and i've run into a problem. The z-axis motors are acting strange. Going down seems fine, but when it wants to move up, the motors just slip. I've added a video to demonstrate the problem.

    Since this is my first 3D printer, I have no idea what the cause of the problem is. Does anyone know what I might have done wrong?

    Thanks in advance,

    Well most of the problems with steppers are the drivers not set right to give the proper current especially when using micro stepping. Going down the carriage has weight to make it drop by itself almost but going up requires more torque and thus more current. You will need to adjust the output of the stepper drivers via tiny pots and since you do have some movement they only need a small turn to get the Z to go upward. You can web search your board for more info or submit a pic to locate the pots if unsure. Turning too much will result in driver getting real hot and shutting down.

      As far as I know there aren't any pots on the main board. I've included a picture for refrence. There is a potentiometer on the power supply, but changing that seems not right. Unless that's the one you meant

        If you look down below Z Motor 2 between two caps by the tip of the crooked heatsink you will see one pot there (beside C23) so that would be the one to adjust don't touch any on power supply

          I think this indeed solved the problem. I also retensioned the x-axis belt to be a bit more loose, as I felt it may have been pulling the threaded rods a bit crooked.
