I am currently trying to print @260°C, it seems that there is no slipping Maybe my temperature is not correctly measured? How can I check?

Thanks, I'm trying Atomic and it seems that there is a lot of dirtiness in my nozzle. How frequently one should do that? And what feeder do you advise?

Actually, I've got the same issue as here: But using the official 2.85 filament

Hi all, My filament is constantly slipping in the feeder of my UM2 I can't print faster than 0.1 layers @40mm/s extruding... For instance: when I change my material and insert it again, I can hear it slips like every second (during the Material->Change last step), I guess that's not normal at all, right? Any idea?

Hello everyone Trying to reduce the frictions of the bowden, I'm considering using a 4mm ID / 6mm OD bowden tube It seems better when trying to move the filament manually inside it However, the original clamps are too large for it (the stock bowden is like 6.35mm OD) I've considered using alternative clamps, like Owen's, but it seems only adapted for Ultimaker1 (http://www.thingiverse.com/thing:11864). I also could add Teflon band to enlarge the tube on the ends... any advice? Is there good clamps that would adapt to slightly smallest tubes?

Takei Naodar, I've tried your design, but I'm still getting troubles If there is too much pressure on the filament, the extruder slips, if there is not enough pressure, the filament is not pushed correctly. Both leads to really bad underextruded parts. Trying to tune the pressure is a permanent nightmare

Hello I appologize for the rude "tldr" request, but is there some synthesis or review of all your work on the alternative feeder systems? I'm interesting in testing one

Printing at a lower temp leads to underextrusions (the extruder slips on the filament) Maybe I should upgrade the feeder?

Actually looks like it doesn't retract at all at this points (So this is not exactly a retrction problem)

My current config: PLA 0.1mm layers 235° Plate 70° Printing 40mm/s, Travel 150mm/s w/ Brim (printing directly on glass) Default retraction settings (never changed it)

Hello all, On most of my parts, I think that my Ultimaker2 doesn't retracts well the filament. For instance, we can see such things: You can clearly see the travel moves on the top layer of this part, this is not normal Any idea how I could avoid this? Thanks & Merry christmas :wink:

In this case you could re-design just the body using SolidWorks, there is PDF drawings that may help you in the repo We already made such articulated robots, like this one: Which is not fully released, but can be already found as "gecky" in the repo sources The code should be adjusted but it appear to work

You mean with an articulated body? That would be doable, are you familiar with OpenSCAD or Autodesk?

About 350€ :-) (including everything, with motors rivets pulleys rivets, screws&nuts, plastic, electronics, battery, charger and bluetooth bee)

Hello, the BOM can be found here: https://github.com/RobotsWar/Spidey/blob/master/docs/parts.md

Hello everyone! Here is a presentation video of Spidey, an open-source robotics platform you can make with 3D printers and ROBOTIS parts: BTW, the "gold" robot on this video was printed with an Ultimaker² Do not hesitate to ask if you want to make the same bot yourself and you have questions

Ok, thanks daid I think we're going to refactor the code a little bit to make the project more uniform We've printed all the 22 parts of a Spider robot in 1 plate (we used the Rep2) and 9h of printing: (French post) http://www.robotcampus.fr/2014/05/27/plater-spidey-en-une-impression/ I may do the same thing on the UM2 soon ;-)

You are right with the licenses issue... We'll likely rewrite our own STL system very soon Actually, we just took like like 100 lines of SimpleModel. We are not fan of GPL-like licenses. You'll remain in the thanks credits anyway :-) are you ok with that?

Hello everyone! Today I'm introducing a brand new tool we're working on: Plater This software is actually a plate builder and generator, it can be used to create printing plates quickly, and optimizing the place took by the parts on the plate. You can give it a few STL files, with quantities and orientation, and some settings like your plate dimension and part spacing. It will then try to place your part and optimize so that it generates the least plates as possible, and output the plates in STL format. You can also release the plater.conf file, a tiny text file that lists which stl should be printed for your design and the quantity of each, so the end users will be able to generate their own plates with their own settings. It is open-source, and it uses somes parts of CuraEngine (ping @daid), you can find the sources here: https://github.com/RobotsWar/Plater We also released binaries which can be found in the official README of the repo, don't hesitate to leave feedbacks

I did another try which looks good, after some discussion I eventually tried to place my spool above the printer with a camera tripod and a simple part: It seems to be a nice tweak, I'll give more feedback soon

Hello, I've already cleaned up mine, same symptoms during a big print-fail, and I indeed used an hot air gun and a pliers

I made a YouMagine: https://www.youmagine.com/designs/ultimaker2-on-the-top-extruder-mod (As you can see on the pictures, my part is partially broken, it does not prevent printing but maybe there is still improvements to do)

Today I've printed a tube to put in the extruding part, it is rigid and now I can use 1.75 filament with that, I'll keep you on touch

Actually, I could spread the part that I'm using to do that, and you could also give it a try

Thanks Daid ;-)
