    If I take it apart, it may never go back together

    Head2.JPGHead3.JPGHead1.JPG

    So I printed a print head and then printed another print head with my printed print head. Say that 10 times fast!

    The first 2 pics are of the one I printed with. Shown after printing. No sign of heat damage. The fan blows on the upper part of the metal the whole time it is heated so it doesn't get enough heat to damage the printed plastic. This was printed in glow in the dark PLA. This design does not require a barrel nut. Still working on better snaps / clamps, whatever. These hold it enough that it will work just fine. But it comes apart a little too easy.

  6. Thanks bolsoncerrado, garufa thanked for this post

    Hail to the king in the North!

    SHAREEEE!!!

    Perhaps you could embed the hinge and clamp of this design to yours? https://www.thingiverse.com/thing:1692395

    Hoooooooooly mooooooooolly!








    What drives me nuts is that this happened on about the 75% of the print completion

    How high did you crank the temp up on that print?

    There is clearly not enough support inside that particular housing.
    Mine do not have space to squirm out of place like that.

    Standard PLA temp.

    Not enough support? U mean I drilled too much? yikes! But I guess this happened because of a clog?! Otherwise why would it got stuck like that??

    Even a clog should not allow the tube to get redirected like that.

    I'm going to suggest this scenario...

    The tube was not aligned with the fitting...
    The edges of new filament pushed the tube into the housing, deforming it...
    again... again... and yet again...
    And the tube continued to draw away from the fitting...
    ...and finally, it just started filling the housing with filament.

    This is something I am seeing a lot on the driver end when feeding filament. It doesn't take much to deform the stock tube.

    This is what was failing my joined tube (joined at the round nut).
    It was working perfectly until over time, the final tube section was getting caught on an edge at the joining.
    It started working at it until it finally failed.

    Don will probably have the solution pretty soon. The better the model, the better the fit.
    That recent update version I did is very similar... even though it is weak outside the printer, inside the printer it is held together... nowhere to go!

    Anyone thought of just leaving the nozzle, spring, and guide tube in the printer and adding the housing as a simple cap with the fitting?

    I'm not sure I care if the two functions are all in one module.
