Disastrous printhead crash against model


Recommended Posts

Posted · Disastrous printhead crash against model

The fan bracket of the UMS5 is held in place only by two small magnets. This week I had a 5-day print going, and in the middle of the night of day #3, the fan bracket seems to have spontaneously opened. As a result, the printhead moved against the model, and the fan bracket was kicked out of its joints.


I think that the upper part of the printhead plastic enclosure is also damaged (at the hinges that attach the fan bracket), and there are three wires coming out of the printhead which are now unattached.


I expect that this is a warranty case. I handled the printer appropriately and there was nothing that I could do to prevent this from happening. I believe that the magnetic holders of the fan bracket are too weak and there is always the risk of unintended falling-off. This really is poor engineering and should be changed!


Might you advise me on what to do? I would not want to send in the whole printer for repair, since the shipment would be very expensive. If Ultimaker sends me a replacement printhead, I believe that I might be able replace it myself.

Is that a reasonable course of action?

    ok, maybe the damage is contained. The fan bracket has been thrown off the hinges, but the hinges seem intact. I could try to reposition it. But can somebody tell me where the three wires have to go? There is a black, a white, and a transparent wire coming from the printhead going to the fan. I guess it's the positve, negative, and tacho signal lead - but where do I attach them?
