  1. I asked Santa for one...or two...or four   :)

    I'd really love one.  But then again, I wouldn't mind a couple Ultimaker 2+ Extended's, so if those prices drop...or people are looking to upgrade and sell their lightly used UM2+ printers...I'll be paying attention  :)

     

    First I was planning on selling my UM2+ extended but the price for the UM3 extended is too high. So I changed my mind and I'll stick to my current machine. Damn! :p

  2.  

    For me "a few" is 2 or 3 ;)

     

    Your telling me " een paar maanden" ?

    and a "paar" is 2 :LOL

    I hear what you are saying, but I already delayed the purchase for 2 months, and I have to make the decision this week :(

    Guess I am going to be one of those buyers, that reads about the new UM3 weeks after buying the UM2's :)

     

    I hope you postponed your buy of the 10 UMs? :D

  3. I did try the Buildtak surface some time ago. The adhesion to the printed parts is so strong that i accidentally broke the surface while removing a part. Theoretically this problem should not happen with the flex base unless the part gets really glued to the base.

    Buildtak sells flexplate as 'experimental'. Although The promotional video looks really promising.

    The experiment costs 150 Euros. I am glad  there are volunteers to try it! :-)

    Keep us posted frederiekpascal.

     

    I've paid 99 euros for the flexplate fyi :)

  4. Retraction on S3D can't be controlled by the um2 just because... Well retract for ultifavor is done using a specific gcode, and the problem of that is that you can't do retract + other movement, it forces a stationary retraction.

    So I would not worry about it, s3d can generate retraction while moving or while changing z, etc. And that's imo much better.

    So not a bug, an advantage.

     

    So in other words, you cannot change retraction settings on the UM2 itself when you use S3D gcodes?

  5. Another demo. Print menu already implemented.

     

    Most of my time is going to refactor and optimize code, otherwise the flash allocation size exceeded 128K, and this has forced me to study and solve other problems. It's being a looooong way.

    BTW changing motor steps/mm is already implemented, it was one of the first things I did ;)

     

    Awesome work man, I'm impressed!

  6. I always keep my dirty nozzles in a seperate place and we I got enough of them then I clean them with a butan torch.

    I hold the nozzle with a heat resistant pair of tweezers to not get burned. Make sure you put a heat resistant plate on the table you're going to do this or you'll destroy your table with nasty burn holes.

    Nozzles that I used for long prints with abrasive materials are going straight in the trash can because they are worn-out. :)

    fyi, a new nozzle costs 12 euros.

  7. Hey guys,

    This is the situation = UM2+ ext with @Tinkergnome firmware 16.08.2

    What happened to me a few times in the past weeks is that my UM2+ freezes after a long print. Not a single menu item is selectable, the UM2+ must be restarted to work again.

    This happens to me 1/10 after a long print. Not a big hassle because it happens after the print but yesterday it happened in the middle of the print. I wanted to check the mm3/sec and I noticed my UM2+ was frozen again, nothing else besides rebooting helped to solve this. I could probably leave it as it was and the print would be finished with the frozen UM2 but I decided to restart the proces. (it was only printing for 2 hours so np)

    I was wondering if anybody else has experienced these weird freezes with an UM2+ and firmware 16.08.2 ?

    Another thing I was wondering about. I'm using S3D and it always overrides the current UM2 settings. But when my S3D gcode has overwritten the default settings, is it still possible to change the retraction settings during the print? Or are the settings on the UM2+ ignored by my S3D gcode for the whole print?

    I'll give you an example. My S3D gcode has most of the time the default retraction settings (25mm/s and 4,5mm). But when I notice that I need to adjust these settings in the middle of a print, is that possible to do this on the UM2 during the print or is it not possible because I don't use Cura?

    Thnx in advance :)

  8. Yes the printer is new one Ultimaker 2 extended + 3D printer.

    It printed about 15 parts and then this molten metal leakage problem occurred.

    i did not change nozzle till now.

     

    What I would do. I would disassemble the hot end.

    You can use this link to follow the steps : https://ultimaker.com/en/resources/22188-how-to-replace-the-tfm-coupler

    You need to clean the leaked PLA in the fan shroud. In fact you need to clean all the leaked PLA on your hot end. Make sure you assemble your printer correctly, this is quite important to have successful prints in the future again. And change your nozzle with a new one. (heat up your nozzle to a least 200C before changing it)

    When you don't have a spare nozzle available, you can try the atomic pull (check this link : https://ultimaker.com/en/resources/19510-how-to-apply-atomic-method )

    And let us know if this worked out for you.

    Good luck, don't hesitate to ask for extra help.

    There are probably more "senior" members available here to give you more tips.
