    Z-axis loosing steps?

    I got a chinese CNC (see pic) and replaced controller with a usb Mk2. All works fine for X and Y but on long runs the Z-axis seems to loose steps (see pic 2).
    I tried lowering speed and acceleration but still got same problem.
    Any idea what could be the problem? Still using original motor drivers btw.
