        <title>Z axis stuck when print starts</title>
        <description> Here&#039;s what happens, pronterface homes all axis, everything moves fine, z axis homes and goes up a bit, extruder heats up, and when it reaches the temperature to start printing, z axis tries to go down a bit but it makes a noise but doesn&#039;t move, like it is stuck. I&#039;m not sure how to fix this, since I can move z manually with no problems. Can somebody help?

EDIT: I have determined that the z axis doesn&#039;t work properly when controlling it from my computer, but moves a bit, get stuck, moves a bit more, but when I control it from the lcd it works just fine.</description>

            <description><![CDATA[ You need to adjust the stepper driver output current depending on the board you have there should be small pots to adjust and they could be off by a fraction of a turn and in this case on the border line of not moving. Locate the pot for Z and turn slightly while running too much either way the more will stop, make noise or overheat. There are exact ways using a meter posted all over web.]]></description>
