  1. You could get a second nozzle and drill it out. I have 2 um2 nozzles - large one is at .7mm. Unlikely to get clogs there. Changing nozzles on the UM2 is a pain. I've only done it twice and the second time still took me 25 minutes.

    If you ask Sander very nicely he will probably give you a second nozzle for free.

    Did you get your jam cleaned out?

    Sorry, but where did you get the 0.7mm nozzle? Would love to get one for my laywood filament

     

  2. My UM2 seems to have a habit of dragging filament with it when it's moving from one print area to another, leading to long "threads" connecting the same old places over the duration of the entire print...

    How can I reduce / eliminate this? I have tried printing slower (doesn't really help), I have tried increasing the retraction distance to 5mm instead of 4.5, and retraction speed as well.

    What else should I be playing with?

    Thanks

  3. I think I just hit murphy's law.

     

    I have a blocked nozzle on my ultimaker 2.

     

     

     

    First I tried this "Atomic method" that everyone is talking about.

     

     

     

    It worked for a few times, and then the last time the nozzle jammed again, i tried it, only this time, the filament broke at the nozzle as I was pulling it up, and the pin i was using to clear the nozzle from below also broke IN the nozzle, leaving it further blocked at the bottom with a broken part of the pin, and blocked at the top with a filament that doesn’t melt even when i turn it up to 260 degrees.

     

     

     

    What can I do here?

     

     

     

    It’s been very frustrating. The nozzle has already jammed up on me like 10 times, ever since i got it 2 weeks ago.

  4. Hi guys

    I'm trying to print this on an ultimaker 2. Dimensions are 8x8x4mm, so it's really small. The lens circle is a gap of 0.5mm, and the little circular hole on the camera is also 0.5mm diameter.

    https://www.icloud.com/photostream/#A35M7GFPa5Ej5;6EBD0F72-BBC9-4F3E-9938-9A11E9F96C7F

    What happens when i print is that the lens circular gap, as well as the 0.5mm diameter hole gets filled in completely.

    How can i improve this print? do i speed up the fan so that it cools faster once printed, so it does not "overflow" into the hole? or slow the print down? any other tips/suggestions? does layer resolution help here?

    Many thanks in advance..
