  1. That's awesome! 

    Now I can finally make custom support structure and print as I wish.

     

    Yes I have UM2, so I'll stick to beta version till official 3,2 comes out.

     

    One more question, hopefully last :D

     

    Sometimes regarding Cura options I have trouble Importing cura profiles. Any solution to that? Can I manually add profiles to Cura installed folder or something like that?

  2. @kmanstudios well yes and no. I printed similar geometry before, and those top layers caused sink marks on 3d print. At least that is my theory.

    But since I can't adjust top layer settings, I'll just add more walls to it will hopefully disappear.

    This is what I do: I make the objects in place. I also go through the trouble of making sure that the pivot points align. Although, depending on software used to create with, this may not be an issue.

     

    Then I export as separate object and then bring them in. Once all parts are in, I give them their individual settings and then select all. Then I either right click to bring up contextual menu or go to edit menu in drop down and select "Merge models". Group models just takes their positions as they are and creates a group for easy manipulation. But 'Merge Models' will put them together.

     

     

    I tried that and it's logical thing to do, but again it seams Cura wont co-operate with me lol 

    When I load models Cura allocate them all over the build plate...

     

    When I load models in Meshmixer, they are perfectly aligned.

  3. Wow so much great info! Ty Guys :)

     

    @kmanstudios so there is no way to adjust or alter that settings in cura for top layers?

     

    @peggyb sweet, this per model settings' 'print as support' is only for Cura 3.2? because it seams I can't find it in 3.1 I mean there is Per model setting but it doesn't have Mesh type print as support as in 3.2

     

    Also how do you set up 2 bodies in one single stl file? It seams that when I create 2 bodies, on export i got one merged body.

    If I load 2 separate stl files, how do I get them aligned in cura, as you did in your example?

     

     

  4. It seams that I always choose to complicate models for simple testing lol ;)

     

    Thanks for clarifying the wall theory.

    My thinking was the same, so after all I wasn't wrong about it.

     

    To sum it up:

    • did 2 mm thickness on model, now vase mode works and I have bottom filled, but again Cura have problem with upper part of the geometry
    • ditched Vase mode
    • I decide to print it in normal model with 2 mm thickness on 3d model, with 2 Wall Line Count, and 0,4 Line Width and 10% infil
    • This results in total 4 walls; 2 outer and 2 inner which gives me 0,8 mm outer line, 0,4 mm space for infil and 0,8 mm inner line
    • total 13h print time :D

     

    And now back to the problem.

    Cura is having issue with this part of my model geometry from the very begging.

     

    With current setting it seams that I'll have top surface printed all the way up, on this model side.

    Why and how to remove printing top surface here?

    It will add unecesery time, but also cause cooling and sink makrs problems...

  5. Yes, that was fun to model indeed :)

     

    BTW thanks for trying to find solution for this problem.

     

    I have take a look at your file, and I see that my understanding how things works isn't quite as I thought.

    Let's start with model thickness.

    You set thickness to 1,4 mm in 3D model

    Line Width to 0,8 mm on 0,4 mm nozzle

    Wall Thickness to 1 mm

    Wall Line Count to 1

    No Vase Mode

     

    Based on this parameters I should have 3d printed part, that have 0,8 - 1 mm wall thickness made from 2x 0,4 mm walls (because of 0,4 mm nozzle) right? I can't make 1,4 mm thickens with above settings, because Line Width is set to 0,8 mm?

    So basically 3d model thickness don't have any role at this point?

     

    But if I set thickness to 1,6 mm in 3d model, and with same settings in Cura, I should get 1,6 mm 3d printed part that is made from 0,8 mm outer wall (2x0,4 mm walls) and 0,8 mm inner wall (2x0,4 mm walls)?

     

    Can you share more light on how to set up and print thin walled models?

     

     

  6. Thnx for all the input.

     

    I have checked, and yes model is sitting on top of build plate, nothing is wrong here. Even if I lift model up, slicer is always showing sliced version on the build plate, without bottom...

     

    Here is mine Shell profile, , I have set up things you said, but still no luck.

    Check if there are some other options I should change.

  7. I have surface model that I wish to print in Vase Mode (Spiralize Outer contour).

    I have created model with Fusion, and checked with Meshmixer, so model is all good.

     

    Now when I select Vase model, slicer shows strange behavior, and I'm afraid that this will cause problem with printing.

    When I set Surface Mode to normal, the part of model is missing from slicer.

    But when I set Surface Mode to Both, again on same spot is problem where layer is missing and shooted in the air...

    Selecting Surface, will solve problem, but leave bottom empty...

     

    Cura version 3,1 (tried also on 3.03 the same results)

    Ultimaker 2

     

    How to solve this?

  8. Hey Geert,

    thnx for feedback.

    I tried as you suggested (only without additional fan, just because I don't have it atm), and with no better results.

    Every tryout with different set of temperature, and lower speed, has resulted with the same outcome, and no improvement at all.

    This is why I believe that something else is causing it.

    Any more ideas, beside temperature?

  9. Hi all,

    I'm trying to 3D print Astronaut Phil, and I have trouble with his fingers.

    Everything else comes out flawlessly, but only fingers are mess.

    Model is scaled to 50%

    Using Cura 2.7.0

    Ultimaker 2

    Material PLA

    Temp 200 - 210

    Speed 40 mm/s

    Cooling 100

    Tried playing with material temperature, lowered the temperature, but it seams to turned out even worse.

    I also played with Motion settings, but no improvements on end result.

    So I believe it is some setting in Cura, that causing this problem.

    Screenshot_100617_034844_PM.thumb.jpg.ba7ed4e48d4ae3ca67648082ef8fc124.jpg

    Any Ideas?

  10. Hi all,

    I have model that outer geometry is surface and inner geometry are thickness ribs.

    Now when I put it in my Cura 2.6 for Ultimaker 2, it only slice outer surface without inner ribs.

    I have tried in Special Modes, under Surface mode select every option there is (both, normal, surface), but Cura only shows outer surface as sliced geometry.

    How to make it work, to print both surface and inner ribs?

  11. I'm searching for data on what is the Print Speed (Build Speed) for Ultimaker 2+ or Ultimaker 3 in mm/h?

    This data should be height-axis print speed, or how much mm in height (Z-axis) can Ultimaker make within one hour.

    I'm aware that this value depends on layer height, but It seams I can't find anywhere official info regarding this build speed, or how to calculate it (other than measure it).

    I would appreciate if you could share it with me, or point me out how to calculate it.

    Also if you have already done measurement feel free to share your results ;)

  12. 1000H with the PTFE coupler not the TFM coupler? (since you use a Spring I thing you still have the old ones right?)

    Your PTFE coupler is dead and you need a new one to fix that underextrusion.

    To get a better fix on the bed use a Brim, a Raft if is a very complex material (like Nylon) or just do

    a) Take bed glass

    b) Clean it with soap and semihotwater

    c) Dry the glass

    d) Put the glass back on the printer

    e) Put some glue on the glass (glue, hairspray applied with a towel (don't ever directly, elmers glue diluted in water with a brush, etcetcetc)

     

    Thanks for the tip.

    Is there some type of test, to check with coupler is it dead, or is it something else?

    Because from outside coupler looks fine (it was changed before some time, I need to check when).

    As for bed adhesion, I did all of what you have listed except using glue. But parts looks very deformed, so I assume that there were pretty much forces from thermal dilatation at work.

    Just wandering if there is some tip on printing large "boxed" part, to prevent thermal dilatation.

    Here's the image of how part should look like.

  13. Material was PLA

    Print speed 60 m/s

    Layer height 0,16 mm

    Material temp 210 C

    Bed temp 60 C

    Hours printed on this machine is roughly over 1000h

    I did bed leveling and testing before I started this long print, bed was leveled good.

    Didn't noticed problem with under extrusion so far, but looking back on some of my prints, every one and then there is visible line, that could refer to underextrusion.

  14. Hello all

    recently I have 3D printed a large prototype and run on strange phenomena.

    The prototype was rather industrial plastic part, with thin walls (2,6 mm).

    What happen is that all corners were bent upside, but surface are above corners is still flat, as it should be.

    What is causing this phenomena?

    I know it has to do with cooling, but does it heated bed caused, or because the part is so big, so the corners cools to fast or something else?

    Screenshot_111316_010719_PM.thumb.jpg.994e985a7dad586169b2b4fe56b5bb56.jpg

    Any tips what to do to prevent this from happening again?

    There were also another anomaly that happen on the same print.

    Roughly 12 mm from top of the part, few layers didn't melted together, and its looks like someone has cut the part with horizontal line.
