UM2 : Z swtich broken?


Recommended Posts

Posted · UM2 : Z swtich broken?

My UM2 Z axis makes loud sound when it starts to print. And it just stops. The screen shows the message. What is wrong with it? Which part I should check?

    The Z end stop switch. It's located on the bottom of the printer (little black switch next to the Z motor).

    You have to flip the printer to its side to look at this.

    Check how it looks, if it looks good maybe the connection is loose, check the electronic board also underneath.

    I you don't have it look at the build manual for the UM2:

    Could also be that you have something stuck under the build plate.

    Normally a screw at the end of the buildplate hits a switch a the back of the machine.
