  1. OK Ultimaker, I ordered my Ultimaker 2 Upgrade kit on 10 March 2016 at my German distributor 3Dmensionals. 3Dmensionals gets info from Ultimaker that at it will last 10 days delivery time. Now i must read it will still last 4 to 6 weeks for delivery! Because I had to pay the invoice of 495€ directly, I am verry angry to have to wait so long and even much longer. Ultimaker should think about a present for our paitent.
  2. www.3Dprinterstore24.de is a really good shop. Really fast support. I bought manny upgrades for my ultimaker there. Maybe you want to try my version of a top cover: https://www.youmagine.com/designs/housingcover-ultimaker-2--3 Last days it was verry hot in Germany! I started to print PLA and heated up my printbed to 60 deg. It was a failure not to remove the top cover. It leeds to clogging nozzle :-( I think it was too hot inside.
  3. I found good news today. E3D offers a new heaterblock for PT100 thermistor. You can find it find it in the shop under spares. In Deutschland kann man das Teil sicher über 3Dprinterstore24 bestellen. Man kann dort auch die Stahldüsen bestellen, obwohl diese im Shop nicht direkt gelistet sind!
  4. Here's another fan Mount design called BLIZZARD. I tried to combine ideas of Spirit and Labern. I'm intressested to hear what you are thinking about. You can find the file on Youmagine: https://www.youmagine.com/designs/um2-fanmount-blizzard-6718ce34-c069-4204-875f-dc0f15989b53
  5. OK I'm no electronic engineer! I can only see two pwm connectors used for fan and led. Am I right that's there no pwm connector left for a servo on the Ultimaker2 mainboard?
  6. I first found the Ultiboard description on GitHub. Now I searched again and found the mainboard documentation. (But my I-Pad can't open it. Trying later on the notebook.) Found coding samples here in the Ultimakerforum: http://umforum.ultimaker.com/index.php?/topic/5188-adding-servo-support-to-an-um1/
  7. I'm actually constructing a new printhead with a dual extruder and a lifting system. Therefore I need a servo. 1. Has the Ultimaker 2 board a free PWM connector? 2. Can I use every RC Servo on these PWM connector? 3. Do I need a special PWM Servo driver? And an additional question because I want to change the fan system. The Ultimaker 2 fans are powered by 12V, arn't they? Thanks for informations, Marc
  8. Here is another concept: I think this one will have some accuracy problems, but it is nice for a brainstorming to find the best solution.
  9. I found a video with a dualextruder like my sketch: I thought it is a relativly simple solution with low mechanical affords. My first sketch based nearly on the length of the UM2 extruder. The accuracy will be better if the distance between bearrings and extruder is shortend. I want to get the dualextruder built in the UM2 and there isn't much space!
  10. There are two main problems with dualextrusion: The two extruders have the same hight to build platform Onzing second extruder Adopting some ideas in this thread I thought about an dualextruderseesaw. Here's a little example how it could look like. Advantages of the dualextruderseesaw: The unused extruder is rotated upwards, so he couldn't crash into workpiece. When the unused extruder is onzing, the material drips on a small platform. The Platform could be extened with a brush at the end, so when the unused extruder is rotated in active position it is cleand. Whats y
  11. Here are the results of the german voting ... for printing small parts. With a layer hight of 0,05mm, reducing extrudertemperature to 190°C or lower leads to underextrution. On such small parts the Ultimaker 2 (and I think all other FDM printers) isn't able to get the right pressure on the fillament for such short printing lines and frequent retractions. For this reason I changed the layer hight back to 0,1mm. Now deviation of extruded material doesn't attract attention so much and the firmness of the small cylindrical pins is better. In addition I reduced the acceleration from 3000mm/s² to
  12. Weitere Infos, Fragen und die Modelldatei findet Ihr unter folgendem Thread: http://umforum.ultimaker.com/index.php?/topic/9088-printing-verry-small-functional-parts/
  13. The Ultimaker 2 is a great machine and I finished prints with great quality. Now I want to print some verry small but functional parts. Don't know if I can wangle it with my Ultimaker 2? First I want to explain my experience with printing a latchingtongue. Maybe some other users can learn of my failures. You can find the model on YouMagine: https://www.youmagine.com/designs/latchingtongue I started with printing the tongue facing upwards and temprature settings for a normal sized object. Hox I expected and you can see on the left side of the picture it didn't work. Then I went on changing
  14. Ich habe zuletzt einen Abstand von 0,2 mm in Z-Richtung und Objekt eingeplant. In der Modellansicht ist dieser in Cura zu erkennen und auch in der Layeransicht wird diese Lücke auch dargestellt. Wie im Bild zu sehen ist das Stützmaterial dann doch nahezu vollständig mit dem Objekt verschmolzen. (Bei einem Abstand von 0,15 mm ohne weitere Änderungen war zumindest noch eine kleine Mulde zu sehen, das Stützmaterial jedoch trotzdem nicht entfernbar.) Ich bin dann dazu über gegangen, das Stützmaterial nicht mehr über die gesamte Fläche zu planen, sondern nur noch Brückenpfeiler zu verwenden. D
  15. Kommt sicherlich auf die Firmware an, bei mir wars das Heizbett (und wenn ich mich richtig erinnere stand bei der Fehlermeldung nichts von "Bed"). Aber ja, die Fehlermeldung klingt sonst eher nach dem Temperatursensor des Extruders. Aber auch hier kann es an der Kabelverbindung liegen. Ich würde auf jeden Fall mal die Steckverbindungen am Druckkopf im Gewebeschlauch und an der Platine prüfen. Meist liegt hier schon das Problem. Letztendlich kann es auch eine andere Stelle der Kabelverbindung wie z.B. ein Kabelbruch sein. Vielleicht liegt es auch einfach nur an der Wärmekopplung des Sensors im
