    UM2+ SD card reader

    in UltiMaker 3D printers

    Posted

    Hello,

    It seems that I broke the SD card reader. It worked well since 2013. Now the printer crash when trying to read a SD card.

    I tried :

    - 4 different SD cards with various speeds => FAILED

    - format them is FAT32 => FAILED

    - flash again the last stable Tinkergnome firmware. Flashed successfully but didn't solved the issue

    - flash again the last stable original UM2+ firmware. Flashed successfully but didn't solved the issue

    The UM2+ is still working with the USB cable.

    My conclusion is that the SD card reader is probably broken.

    Someone knows which manufacturer / part number they use ? It's not mentioned in the BOM on github.

    I don't know if there are more details in Altium. I cannot read the files...

    Thanks

    Best,

    Mark2 Upgrade

    in Third party products & modifications

    Posted

    Hi,

    I have an Ultimaker 2 without any modification except the Olsson block.

    I would like to upgrade to the Mark2.

    Can I buy only one UM2+ upgrade and use the original print head with Olsson block as second head with Bondtech feeder ? This will save me a UM2+ upgrade kit ;-)

    In the Mark2 essential, is the PCB included ? Are they available ?

    Thanks !

    Cheers

    NFC specifications

    in UltiMaker 3D printers

    Posted

    Hi,

    Do someone have the specifications for the NFC tags and readers ?

    What kind of NFC tags are used ? Do someone have a datasheet or the part number used ?

    I would like to be able to read the data on the tags and write new tags from a raspberry pi/arduino

    Thanks

    Cheers

    We would like for sure to get the Ultimaker data (both filaments and settings) with pleasure on the website. The database behind is able to handle terabytes of data.

    We will add slicers export before the end of 2016 for Cura, Simplify3D, Kissslicer and Slic3r.

    Even for UM3, users may be interested into having other options for many reasons like type of plastics, composites, cost, color, etc... They will need a way to find and source them. They will need after to find the right settings.

    For the pictures of the settings on the website, they will be added in the next release.

    We will release also an explore page where users can see what others printed.

    Thanks for the feedback !

    I created Filaments.directory to help the community to find new filament with ease by collecting data about filaments all over the world. I launched last week a new feature where users can share their print settings for the combination printer and filament. The goal is to collect as much data as possible, create default profile and avoid the trial and error process when using a new product. All the user's settings are shared under Creative Commons by-nc-sa/4.0 licence.

    I launched a contest to celebrate the new feature with Wanhao, Colorfabb, Extrudr and Innofil.

    If you register on Filaments.directory, you have one chance to win.

    If you share a print setting, one more chance. The more you share, the more likely you will win one of the 35 prizes.

    Contest : I want to participate

    Thanks for your help !

    PS : we like feedback. If your filament or printer is not listed, please comment this post.

    Under extrusion ?

    in Improve your 3D prints

    Posted

    I will see for the parameters tonight.

     

    I found also a bowden tube problem.

     

    I had a massive bronzefill problem. The head was full of bronze. The filament in the bowden tube was pretty hot. I found that the inner diameter of the bowden tube is too narrow the last cm.

     

    I have to change it. Do you know if the bowden tube on the online store is compatible with the UM2 ?

     

    Thanks

    structur3d / discov3ry paste extruder

    in Third party products & modifications

    Posted

    Hi,

     

    I found the project on KickStarter :

     

    It's an universal paste extruder who will work with any FDM 3D printer with stepper motors. What's your opinion ?

     

    Someone have experience with paste 3D printers ? What kind of paste works well ?

    The new head can be too heavy for the actual UM/UM2 head ?

    What about the slicer ? Who control the extruder ? Will it affect the UM/UM2 long term reliability ?

     

    Thanks for comments

    Support software

    in Improve your 3D prints

    Hi,

     

    I tried Cura and Meshmixer to support my prints.

     

    IMHO, Meshmixer support structures are far better than those with Cura :

    less material, better support, quicker prints.

     

    Is there other good softwares : general or specific purpose.

     

    Thanks

    printing a big spoon...

    in UltiMaker 3D printers

    Posted

    Cura only adds two supports at the left and right side. The PLA was too melted and the supports had fallen into the sides.

    The bed was cleaned with a new thin layer of glue.

    The spoon is not flat... I will try with a lower bed temperature and heavier supports.

    Thanks for advices.

     

    printing a big spoon...

    Hi,

    I try to print a big spoon with PLA 210°C, 75°C heated bed, 50mm/s:

    cuillere

     

    The results are here : https://imgur.com/a/Ss6Yw

     

    I tried to print it vertically with meshmixer support with brim in cura with 30 loops => no success, not stable enough

    I tried to print it vertically with cura support and brim with 30 loops => not stable enough

    I tried to print it horizontally with meshmixer support => not enough adherence on glass... even at 25mm/s

     

    Do you have an idea of to print this ???

     

    Thanks
