  1. Ah, sorry I put the info in the image description, forgot to do so in the post. It was printed at 0.1 layers, sanded lightly and then polished. Didn't take too much time. The rounding happened while sanding, it thought it would give a more realistic metal look.
  2. My first print with bronzeFill. It's just a small ring I designed for my girlfriend's upcoming fashion show, but boy that filament is awesome. There's absolutely no way you could tell it's printed.
  3. Like I said on G+, well deserved!. I have always seen this community as part of what Ultimaker is, and that makes a product which is awesome on it own even better. Keep being the good guys, and we'll keep spreading the word.
  4. Bah, ordered 5 spools like three days ago. Just my luck. :oops:
  5. For adding detail to a model (and I use "detail" on purpose since texture means color data in 3d modelling language), you have 4 options. A.) Physically model the details, either from a NURBS surface or subdivision surface, depending on the software and workflow used. B.) Use a black&white texture for displacement mapping, where polygons on the object get displaced according to the information in the texture. C.) Scatter objects around the base mesh (like the C4D example above) and subsequently use boolean operations to attach them together. D.) Use a "sculpting" program, which is in
  6. Yes, but bear in mind that is for "heavy loads and constant operation". It's safe to assume driving an extruder classifies as both, while your application may not.
  7. Oh and yes, the retraction is a problem with flex shafts due to the winding. There will always be some backlash there, since they are generally manufactured to work either clockwise, or counterclockwise. I have heard of some specialty shafts which can handle both, but don't know much about them. There was also a patent I found for an anti-hysteresis flexible shaft for use in surgery. I even remember how it looks, but I've never actually seen shafts like that manufactured.
  8. To be completely honest, I have none. The prototypes I used were abandoned after the first few tests in favor of a small motor based approach, which I'm developing ever since. I've never tried a 1:40 gear set, because all I had available at the time was a 1:20 set. And with that the prints were a complete mess. At one point we measured the angle at which the worm turned when manually moving the head from the front left corner to the front right, with the extruder off, to check hysteresis. And it was a lot, but I can't remember the angle, it was ages ago. In the end that influenced the quality
  9. I've read in various engineering books that all worm gears should always be lubricated, due to the way they transfer power. But here's an excerpt from SDP/SI webpage: It's up to you to keep them dust free in the process I guess.
  10. Great stuff foehnstrum! Do post the pic of the finished print, I'm super curious to see the results. Also how come you haven't greased the worm gears? From what I've read worm gears shouldn't run dry or they wear much too fast.
  11. I don't know if this has already came up before, read through the threads and didn't seem to find it. So here goes.... From a visual aspect there is one thing I find horribly irritating whenever I use YM. And that's the "Show more" button. It's placement is completely illogical for two reasons: 1. It is placed above the actual content it relates to, which is nonsense from a user experience standpoint. Logically, a user would be interested in seeing more of something after he's seen what there is to see in the originally offered content. 2. If for some unknown reason it has to be so, at le
  12. That should work, I have no clue if software endstops are turned on in the default firmware though, somebody might know more about it, I don't use the firmware from Cura. A simple way to try is to start the printer and home it, then move slowly towards the end to see if it will stop with the endstops removed. If it does, you're good. If it doesn't it's an easy fix.
  13. Funny, it was up there for a moment, I saw it, and now it's gone with a 404 error. ?!? As for the endstops, that's not about Cura per se, but about the firmware. If the travel length is set up right in the firmware, it should work as normal.
  14. Haha, glad to hear that, that was the purpose! Do add the print on the YM page if you don't mind, so people know it works. I don't have a decent pic of this model, I use a previous iteration on my printer which is not as pretty as this one. (and I must say it does look really nice on your printer!)
  15. I removed the max limit switches ages ago. I constantly experiment with printhead designs and therefore my print volume, so the max switches would have to also be moved all the time - much easier to just do it in firmware.
