  1. If i grab the nozzle tip, it has a bit of play, aswell as i small click noise, comming from one of the linear ballbearings, so i have a feeling that the problem may be related to this.

    My long belts wont produce a note anything like that, so they must be to slack, adding further to the problem. How do you apply the clothespin springs? i collect them when my plastic clothespins break, so got a bunch in spare!

    All my axles got a bit of endplay, so how can the endcaps be to tight? I got sort of an ocilating feeling when pushing the head around, which seems a bit odd.

    I unmounted the axles a while back to replace the drivebelts, and all axles rolls properly on a glassplate.

  2. How many hours did you put into that project. Must have been a few.

     

    I really have no idea, from time to time, i find it hard sleeping.... ;)

    a rough estimate is about 100 design hours and 60-70 print hours.

    You cant upload video to this forum?

  3. Ive made this automata as a birthday present for a good friend of mine.

    Its called "Flight of thoughts"

    It function as follows:

    First a gear is selected, high or low, which determines flight speed and rotational speed of propeller. Then the user determines the flight plane by actuating the control stick

    And lastly the motion is formed by turning the crank.

    The plane can then be controlled in flight by the control stick.

    The design uses a swashplate design to give path, which both rasies and lowers the plane, aswell as choose a fitting nose attitude (pitch). The gears and links are merely for control and actuation.

  4. Sure as sure! ive taking shrinking into account when i designed the part, usually i go for about 1,5-2% increse in dimension to compensate for shrinking.

    The problem is that it is not uniform, and the same error dont show up on the outside as on the inside?

    ive been watching the print for some time, and a think it maybe has something to do with the "rotation" of print direction. The outside is always printed in one direction, while the direction changes on the inside.

  5. Hi everyone!

    Im experiencing some troubles with my UM1

    First off, i have holes which is oval, for an ø49mm part i get diameters between 48.3-49mm. I think that is a bit to much? anyone have experience here? My short belts are tight, and the long belts are also ok. They have only done like 30hours of printing.

    Next off i get decent surface quality all around the outside, whilst in the hole down the middle i get this "laddering" or steps, as if the layers are badly shifted, what can be the reasons for this?

    I think these problems are related somehow, but since my belts are tight, i dont think its backlash.

    ive added the following pictures to show the problem.

  6. Hello everyone

    Im in search for a good dual fan setup, much like that on the new UM2.

    First problem: Currently im printing thin (ø5-6mm) cylinders, and the surface on the "shadow" side facing away from the fan is melted an odd.

    Second problem: Printing these thin cylinders, my overhangs get bad, so i guess fan shrouds wich sits close to the nozzle would be preferble?

    i need your designs, ideas, thoughts on thei subject. Pictures of various type os shrouds would be mighty fine!

     

  7. Targeter - fantastic print!

    What is not printed in this model? Would love to try and print it myself. ;)

     

    The tracks are assembled by 1x15mm nails

    The axles for all wheels and rollers are either 3.3mm or 1.6mm stainless welding rod

    M3 bolts and nuts for the turret

    Lots of loctite precision glue :wink:

     

    @Didier.. haha Great video! Is that your wife, girlfriend? How did a geek like you catch such a pretty thing :p:p

    @Targeter Cool little models, how many parts per the tank?

     

    Im not sure of the exact parts count, the tracks are like 180 links or so each, and the tank itself is 40-50 individual parts.

     

  8. Ive recently finished the wirbelwind turret for the panzer 4 chassis. The chassis itself is still on my desk in peices, so i borrowed my other one for display purpose!

    the finished chassis will have accomodation for boxes containing spare barrels at the engine ventilation on the sides of the engine deck.

    For the interested reader, the wirbelwind was intended to support the panzer division with much needed airsupport. The wirbelwind, equiped with quadmounted 20mm flak38 guns, excelled at engaging low flying aircraft aswell as light ground vehicles. The combined rate of fire was about 1600 rounds/min, which was requiered to engage low and fast flying fighters, this explains the open topped design, the guns produced massive amounts of smoke!

    The gun was manned by the gunner, training and firering the guns, aswell as two loaders with acces to about 3200 rounds of ammo.

    The wirbelwind (and ostwind) was later intended to be replaced by the closedtop kugelblitz.

  9. Panzer IV

    My interpretation of the workhorse of the wehrmacht. Panzer IV. Currently its lacking pintle MG34 and headlights. Its fully poseable and has working threads.

    Me and the SO paid a visit to the german panzer museum in Münster, and filled a bunch of CF cards with pictures, so currently om working towards modelling a full set of wehrmacht vehicles.

    Modelled in solidworks, sliced in cura, printed on ultimaker, glued together by me!

     

  10. Its nearly 2 o'clock in the night here, so i have a hard time taking good pictures.

    I will start a new thread first thing in the morning.

    My main problem is get very messy outer shells (upskin?) when i print parts with many retractions. Many horizontal lines protrudes from the surface.

     

  11. Hey everyone!

    Greetings from Denmark, ive been proud owner of am ultimaker mk1, for nearly 2 years, and a forum lurker for just as long.

    Ive decided to join, since i need some help and advice, concerning wether my machine is worn down, or im just overlooking something.

    Hopefully i can also contribute in return with whatever knowledge i have gathered for the past 2 years.

    My main interests of 3dprinting is: prototyping and modelling. And i mainly use my ultimaker for scale models, mechanisms, acoustic equipment and various daily day items. Also i have been doing some minor prototypes for a couple of firms.

    Im working as development engineer, and i built machines for internal logistics, and robot tools. I graduted with a bachelor of science in mechatronics from Southern University of Denmark in 2013.

    Im looking forward to joining this fine community.
