  1. I just finised some maintinance on my 3 ext. and when I when to put the door back on I found the upper hinge had a small piece missing. So now the door falls off. I am hoping there is an upper hinge STL file someone can share.

     

    Thanks,

  2. I am looking for help with my UM3 extended. When the extruder moves on the x-axis I get a Grrrr sound coming from the corner with the x-axis stepper. After a x/y axis test I show a fail on the x.  I have already checked the belt tention, it was good and I found noting bound up or rubbing. I took off the side, checked the bearing, it is free and smooth. I can turn the stepper by hand easy enough. I can feel the steps of the motor and it does not feel like it is sticking. I looked thru the menue for a way to just move the x-axis stepper but could not find one. 

     

    Now I am looking for more ideas on when I can look next for a fix.

    I have started this part 4 times now and it does the same thing every time. The brim goes down like a champ and then when it starts the criss-cross pattern I start to see small bits of under extrusion. The spots get progressively worse until extrusion stops all together. I unload the filament, if I am lucky. Most of the time I have to take the extruder apart and reload. You can see in the other 3 attached pictures what I end up with. The hot end is always a little fatter with a bulge right at the spot where the filament leaves the bowden tube. The next two pictures show the filament where the extruder fails to feed but then does okay for a bit (the out of focus picture) and the last picture is of the spot it leaves when it gets stuck for good.

     

    I have cleaned the extruder, changed filament (currently have a brand new role on), checked my level, checked the tension on the extruder feed wheel and tried leaving the door open and closed. I get the same result every time. The last two parts of similar size came out just fine. 

     

    I also attached the profile I am using. Any help would be great. This part not printing is holding up a big project.

     

    Thanks,
