Irregular extrem quality loss / Extrem Bad Printing Result

Posted (edited) · Irregular extrem quality loss / Extrem Bad Printing Result

Hello Guys,

since last year october i can call myself an "Ultimaker 2 Owner". The first printing results were perfect and i had a lot of fun with my new gadget. This january i changed the old nozzle and heat block combination to a changeable nozzle packet where i can chose between 0,25/0,4/0,6/0,8 mm nozzles. I installed the standart 0,4 mm nozzle, calibrated the ultimaker 2 and tested it.


0,4mm Nozzle

210°C Extruder Temp.

65°C Bed Temp.

Standart Ultimaker 2 Filament (2,85mm)

The first results were incredible good, perfect as always.

The first print was the "Ultimaker 2 Robot" and the quality was fine.

The secound print was this "8mm3" thing...


The third thing was a bigger part, the bottom part for a Raspberry Pi Board...


All the first prints were perfect and i was very luckily, but then something weird happend.

I tried to print the top-part for my Raspberry Case and the result was horrible...

1st try:


2nd try:


It looks like the printer had some problems with the axes, because on picture "1st try" you can clearly see a shift of one axis. On the picture "2nd try" it looks completly bad without any good reason. The first layers are always good, but after some sucessful printed layers the Ultimaker 2 starts to produce some bizarre results.

Does anyone also have those problems? I appreciate every kind of help.

Thank you.

    Hello DidierKlein,

    great idea. Thanks!

    I tightened the small screws and it helped first very well, but 1 pulley seems like to have no tension. The screws are very tight and i cant perform more pressure on them...

    Could it be possible that this one rubber has any malfunction and has loosen its tension?

    I just bought the Ultimaker 5 Months ago...

    Which pulley? Does it rotate on the rod?

    You talk about the belt, is it loose?, if it's a short belt you can tighten it by unscrewing the four screws that hold the motor (just a bit) pushing the motor down (you can also do this by pushing the screwdriver down when holding the bottom screws).

    Then tighten the screws back

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
