First Print, need some advice


Recommended Posts

Posted · First Print, need some advice

This is the first print I've made with my Ultimaker(original). Using the filament that came with the printer. As you can see, something is off. Any advice would be greatly appreciated. From other images I've seen it looks, to my untrained eye, as if it isn't hot enough - but at 220 that seems off. Happy to provide any other information that is helpful!


220 print temp

50mm/s print speed

Fill Density 20%

Layer height 0.1

Shell thickness 0.8

    Ha! Yeah something is off.

    I think it's underextruding due to extruder not tight enough. Can you provide a photo of the extruder both open and closed? Try tightening the screw until the spring is compressed to about 11.5mm (when it is closed on the filament). When you close and latch the extruder closed, does the spring compress/move slightly? It should.

    If you don't have calipers I suggest you buy some. They will be invaluable going forward.

    The extruder should be able to pull 22 pounds of force on the filament you could try testing this. Of course it won't do 22 pounds while the filament is also in the head but if you back it up half way down the bowden tube you can try pulling and turning the big gear by hand at the same time and try to device a test that determines how much pulling force it can achieve and still move the filament forwards.

    Well I couldn't find the same screw, there is another shop that will be open monday that may have it. In the meantime I tried to straighten the damaged one to see if it affected anything. The printing looked worse at first, then I double checked the caliper measurement and made an adjustment and it appeared exactly the same as what was pictured above.

    Should the smaller plastic wheel be moveable? I noticed when I tried moving it with my finger it didn't budge, even when completely unscrewed.

    Ah! That's probably the problem. That black plastic material is called "Delrin". Delrin is easy to cut with a laser cutter and UM has one so I think that's why they use that material here. The Delrin wheel should be spinable. Maybe the sides of the extruder are squeezing it too much. You need to fix this before printing anything else otherwise it will get worn down and will get a flat spot.

    Great information, pictures, and replacement if you damage the delrin wheel (and a better design I think):

    Great info thank you!

    I discovered the source of my problem, what was keeping the wheel from turning. The side parts were potruding on the sides as if the wheel was shoved inside but didn't fit.


    So I took it off to get a better look and it was pretty clearly not fitting correctly.


    I pulled the wheel out and compared it to the images to the ones at this link: http://wiki.ultimaker.com/Ultimaker_rev.4_assembly:_Material_feed_mechanism and realized the side parts were installed incorrectly.


    So I took it apart and pieced it together, but the sides are clearly warped.


    The middle piece is also damaged, probably related to the damaged screw.


    This is a preassembled kit I purchased from Makershed. I'm worried that these parts are too damaged because of incorrect assembly. Should I contact Ultimaker support to see if I can get replacement parts, or Makershed?

      • 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 5.3.0-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.
