  1. Hi Amedee, is there any way not to show the extruder 2 and 3 temps on the smart controller? Everything else works as expected! PS: Is it worth to upgrade the belts and pulleys to GT2?
  2. Thanks, the my problem is because there are so many different versions of this printer :S
  3. Does that also apply to the ultimaker Original with the 1.5.7 Electronics board. I currently have two 12v fans, and after reading in forums, bought a 24v impeller fan, connected it and it blows very vey slow.... and only with PWM higher than 175, so makes me think that maybe it is 12v. I attach the design down here
  4. On The Ultimaker original, does this apply too? I find my self struggling on how much is too much and how little is too little pressure, The knurled bolt on the original Ultimaker original has a different pattern than on the UM2 (I think), so I guess this apply differently right? how much is the right tension? I can't find any post explaining this, Only found the Ultimaker website, where "no marks" is too little and "material grinded" is too much
  5. A ver varios temas. yo tengo la original y me va estupendamente, la encontré de segunda mano por 800€ en madrid con 4 rollos cama caliente ulticotroler... el motor del extrusor hace mucho ruido pero hay un damper en thingiverse o youmagine que te puedes imprimir para evitar esto, de todas formas es mas ruidosa, al ser una caja de madera, en el tema de materiales, nylon no he probado policarbonato tampoco pero temas flexibles he probado el flexible de ultimaker que va bastante mal hay que imprimirlo muy lento, pero esto es un problema de diseño de todas las maquinas que no llevan extrusor
  6. Add supports, it helps with the overhangs, It has a great potential, but needs to be studied, you can check iluminartis post at extrudable.me
  7. So right now I am printing over cristal (just placed over the aluminum) prints got way better, I think its due to what you say, the bed leveling, I think that the aluminum was not completely flat, cristal should be completely flat, and has a very difficult chance to be deformed. I didn't have time to check thing, and try other, just printing over cristal heated to 65ºC sprayed with hairspray, It sticks perfect, and its a little bit triky to get it out, but I didn't have time to make a 9 hour print and have that risk, so thats what I did. I'll try printing bare on the cristal next time, also
  8. English its not my main language, thats why I don't really know how to call it, So the problem with the overhangs its solved by less temp and more cooling? I've just installed a second fan, I'll try that later this days. Is there any source files for the WHOLE extruder in order to re cut it or re print it, because I have some broken wood parts there, In the github Ilustrator file there are not all the files from the extruder just the two hanging things ( My UM its a revision3, I don't care upgrading it to Rev 4 extruder)
  9. Thanks for answering, We should make our ultimaker go direct extruder in order to extrude this materials in a better way. http://www.thingiverse.com/thing:110269
  10. Hey, is there any printable flex material that could print RC tires?, My dad its a big fan of them and he wants a specific tire dimension that its not in the market
  11. Yo me compre una UM original por aquí en madrid de segunda mano (por el precio mas que nada) de todas formas tendrás que estar atento a ver que se habla en el foro sonbre el tema del extrusr que estaba dando problemas, no es un tema de activarla o desactivarla, todo el mundo creo que la tiene activada para evitar que se formen esos hilitos http://www.jonshobbies.com/wp-content/uploads/2013/04/3D-Printer-OB-1.4-stringy-Y-Carriage-in-PLA-Closeup-zero-retraction.jpg
  12. La retracción siempre se activa (o casi siempre) consiste en que la maquina retrocede el motor que expulsa el hilo, ya que por su propio peso o inercia seguiría cayendo dejando hilos, de esa forma te los quitas, hay otra cosa que es el combing, que es parecida, que la maquina no retrae, pero hace un camino sobre la propia pieza para así si deja hilo que lo deje sobre la pieza (este hilo es depreciable en la calidad de la impresión, excepto si eres como yo que en la primera capa no me gusta el acabado que deja)
  13. Hmm, I'll try that, Right now I am printing a Ultibot with a new fan, I'll post the pictures if there are differences,
  14. I am finally starting to get great Prints, by slowing down the speed of the shells and increasing the infill speed. 1.2 mm of shell I still have some problems with the over hangs bending upside, and then the nozzle pushes them down, then they bend up again and like this all the time, I think its a problem of cooling
  15. I like the idea, But not the way to develop it, Isn't there any software way to develop that? PD: that Usb power, as someone told me(I don't know if it is true), can damage your computer PSU.
