reassembly of the nozzle after unclog


Recommended Posts

Posted · reassembly of the nozzle after unclog

Hello,

I had to remove the nozzle from the aluminium heater in order to clean and unclog it.

Now i am trying to put it back but i cannot get it to fit into the aluminium block. There is a 1mm gap between the aluminium and the nozzle.

What should I do to get it back in place ?

thank you for your help !

    First check that there isn't any PLA in there that is preventing you from tightening it. If there is, try heating it up and remove as much as you can and then, while it's still hot, try tightening the parts together again.

    If it isn't old PLA getting in the way then perhaps the brass tube has gotten screwed in a bit too far. Back it out a few turns, then screw on the nozzle tight and finally tighten the brass tube back up so that it connects with the nozzle. It should look like this when you're done:

    I always assemble and disassemble at 180C. It means I have to use tools instead of my fingers but that always works best for me.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
