  1. Yep.  Checked pulleys.  I bought the box from Ultimaker so I can ship them one of my UM3Es.  I'm just going to have them go over it.


    Something curious did happen though.  On one of my UM3Es, I produced an amazingly beautiful print (no changes from me, I've been cranking out prints 24/7).  Excited, I printed another part.


    Exact same printer (UM3E)

    Exact same slice settings (default 0.1mm fine)

    Exact same filament

    Exact same orientation

    All parameters I can think of, consistent

     

    And yet I produced two very different prints.

    What could cause this? (look at the difference in the black piece)No photo description available.No photo description available.Image may contain: phone

    Just wondering: while printing, can you see it stuttering? Or if you put your finger on the head, can you feel more vibrations in the head than in the other printer? And if you put your finger on the feeder, or the filament just before the feeder: do you feel (more) stuttering? This might give a clue whether it is mechanical in the head drive train, in the feeder traject, or electrical due to temperature changes, or power supply changes, or interference or something?

     

     

    Good tips

    The feeder feeds really smooth.  Doesn't seem to be an issue there.

    The head does stutter, but not anything I haven't seen other printers do - especially if it comes to infill between close walls.

     

    Remember, this issue is only happening on one axis.

  3. Team,
    First and foremost I wanted to thank you all for being so patient with me in working through this.  I am grateful Ultimaker has such a great community that people would go out of their way to help strangers.

    That said, here is the print from the second printer - same exact settings.
    Both printers were bought used from the same ex-retailer. 

     

    Belts have been tightened and greased.

    Build plate screws are in and stable - I manually level it and active leveling is on.

     

    I will film a few layers and see if that answers any questions.


    I have tried prints with achingly slow speed, acceleration, and jerk.

    Are you sure your filament is dry? do you still have your 2+?

     

     

    Yes 100% the filament is dry.  It was brand new prior to printing.

    I have put hundreds of prints through this printer with tons of different filaments.  It is not a filament issue.

    Here you are:

    UM3

    AA 0.4

    Latest cura, default setting 0.15

    Polymaker tough pla blackIMG_2472.thumb.jpeg.c126477a2cbd33d62fe349219420d048.jpegIMG_2473.thumb.jpeg.4b218f20784b20fa6778e484d973df5f.jpegIMG_2474.thumb.jpeg.3d91e0beea1972fad52a03dd6b089fa9.jpeg

    The damage to the brim is a result of a to high adhesive from the first layer (normally i di a Z 0.1 offset)

    Greetings,

    I'll have two on each printer tonight.

  6. I miss with brims and rafts supports very often

    I also change infills and speed depending on if i'm prototyping or not.

     

    I've re-downloaded the STL you linked to make sure we are on the same page.

    I will print that cube using the purchased ToughPLA on each of my 3E machines and report the results.

    I hardly ever change the settings. I tend to just stick to the default profiles that Cura has.

     

    I run defaults on my 2+

    The only reason I fiddled with the 3E slicing settings is because of this issue

     

     

    I am printing a high poly cylinder and a medium poly cylinder now on the same print to see if it's an STL export issue

     

    ToughPLA also arrives today, so let's coordinate on what we would like to print

    Hi Crono986

     

    I write that you don't think we are ignoring your problem, but I guess and thats also my problem, that you have already tried all the good advises we normally give. Why in your case nothing helps is a good question and to be honest I don't know.

     

    Is this a new printer or a used one? 

    In case of a new printer I would really get in touch with your reseller. In my opinion there is something wrong with the printer, but on the other hand you have nearly replaced or checked everything which could cause the issues.

     

    Thank you for the reply.

    It is a used printer from a previously certified Ultimaker reseller (they don't sell Ultimaker any more).  They have been troubleshooting this with me for two months.

     

    I believe, since all the forums and Facebook groups and people I have talked to have given me their advice and I have still been unable to solve it - that sending it back to Ultimaker is likely my last course of action.


    Can I at least get confirmation that this print quality is not normal?

  9. Bump again.


    I have tried everything and would really appreciate some help.

     

    I have done everything from:

    replacing card, tensioned belts, lubed axles, played with cura settings, including:

    changing print speed, acceleration, and control, editing layer height - just about anything i can think of

     

    the Y axis has trouble lining up.  here are some images.

    UM3E on top, UM2+ on the bottom.  Look at the inside of the C and O

     

    2.thumb.jpg.b3deb43ef5d4f49a70cc517feed71267.jpg

    The 2+ is almost perfectly aligned

    the 3E is shoddy by comparison

     

    Here are the Y faces of the Um3E test cube, left is 0.06mm layer height and right is 0.15mm layer height at 30mm/s

    5.thumb.jpg.2cc1835ad2e54756dd05398211dcbddf.jpg

     

    The X face is actually quite sharp, but you can tell the layers don't line up with one another because the Y face is shoddy.
