Yea you are right I really want to use roberts design! =) https://www.youmagine.com/designs/alternative-um2-feeder-version-two

The Ultimaker is often used for showcases and exhibitions. So it gets transported alot between locations. I want to remove everything possible that "sticks" out of the printer to make these transports more hassle-free. The ultimaker2 feeder mecanism is so simplistic and small that it is perfect for what I´m up to. It´s also a dual head machine so the space I would save would be segnificant.

Hi everyone, my newest project is to put an Ultimaker2 style material feeder on my Original machine. I already "googled" for the specs of the UM2 feeder motor and found this google group: https://groups.google.com/forum/#!topic/ultimaker/qCBoH9TX6z4 So the specs are: Nema 17 Bipolar Stepper 0.9° Step angle 400 steps per revolution 44 N*cm holding torque The one I choose is this one: http://www.exp-tech.de/Servos-und-Motoren/Stepper-Motor-68-oz-in-400-steps-rev.html The things left to do are to change some settings in the marlin firmware but dont know what exactly. I know that have to set the new 400 steps/rev and have to change the settings for jerk and accelleration. But I dont know where to find this in the firmware and to what values I have to change the jerk and the accel settings. Thanks in advance guys, Lukas

I'm using HIPS at the moment and orange oil (or D-Limonen) as solvent. Its perfect for use with ABS and PLA because there is enough anhesion between the different types of plastics so everything stays put but also there is no real melting reaction between those and the objects stay seperated from one another. And with its easy handling, a same pricepoint like ABS/PLA and a solvent that is easy to get and also not very expencive (and good smelling by the way ) its by far the best support material i've ever had!

Hey, a few months back I started a thread about intelligent ways for creating support material based on my experience with a printer from stratasys. Since I'm no programmer and can't help with implementing those features I think these features would be hard to take on. But there is one setting that could be implemented with relative ease I think. The slicer from stratasys gives the support a solid top of 1 to 3 layers (can be set in the settings). For solouble support material this feature is just golden and guarantees a nice finish of the outer shell of the main object. And the support material dont have to be so dense to get "near perfect" results. So Daid, would it be possible to get this feature in Cura or is it to hard to implement? Greetings, Lukas

Hi, I just bought the merlin hot end because it really looks very promising! =) I also bought a 4.7kOhm resistor for the thermistor. My problem is that I dont exactly know where I have to solder those? I have a dual extruder setup so I bought everything twice! Are the pins I need the ones marked as: R21 and R23 near the temp sensor connections? And my last question is: Where do I connect the new temp sensors? Do they also come on the little PCBs on the printhead? Thanks for all answeres in advance guys! =)

Thats a real bummer with the patent. But the first setting I mentioned is also kind of used in KISSlicer if Ihave looked correctly. The beginning of the support material is rough but when it comes closer to the objects surface it gets more compact and dense. I would really love to see that feature in Cura!! =)

Hi, The design department in our university where I study has got an ney 3D-Printer from stratasys. Because of my experience with the Ultimaker I was made partly in charge for it. While playing around with it I noticed some things in the slicer which are very helpful. So I thought that I could post my findings here because I think that they would be very good additions to the already extraordinary cura! =) It's mainly about the support material and how so save as many as you can without decreasing the overall print quality: The first setting for support material: You can set the density of the support like the fan settings in newer cura versions which means that you can for example say that the support material will have 15% at the beginning and when it moves closer to the object the support density will increase for example up to 50%. This way you save material and print time but also get near perfect surfaces under the support material. This setting is very good for dual printing and solouble support materials. The second setting is also about (solouble) support material: You can set that the support material will be the same material as the main object at the beginning and when a specific distance to the object is reached it changes to the second (at best solouble) material. This way you save print time because of less head switches and save money, because solouble material is way more expensive than ABS or PLA. The third and last: You can set, where every layer will be started. Every time when an new layer ist started, there is a little visible damage or blob on the surface. These little damage is caotically distributed all over the object in cura. But when you concentrate these damages to ony one area in the object, you also have only one area for the post-edeting. For this feature its important to be able to set where thes area will be so its not set at the front or an other important part of the object. These are the features that I found most interresing and thought that they would be nice to haves in our loved cura and to make it perfect for solouble support material. So Daid, are these settings possible to implement in cura or are the too complicated to do so? Kind regards, Lukas

Thanks Daid, I will try. So I need a stepper motor with these specifications: 2-2 Phase Bipolar - Unipolar? Each phase draws current 1A / 1.2A at 3.5V / 3.6V Steps / Step-Angle is important for accuracy (I believe the stock ultimaker motors have 200 steps?) Is that correct, or is there more?

Where can I find the specifications for the motors used in the ultimaker? I can't find the datasheet or a description in the wiki... :/

Thanks for the tips. If I have understood everything correctly: Can I use this motor? http://www.stepperonline.com/9deg-nema-17-bipolar-stepper-12a-11ncm156ozin-17hm081204s-p-99.html

Hi everyone, I would like to build a direct extruder. I know that it would be good if things don't get too heavy. So my question is: Can I use other, smaller, stepper motors than the ones that are included with the ultimaker to save weight? And if yes, does anyone know which motors can be used?

Hallo! Ich heiße Lukas, bin 23 Jahre alt und melde freudigst einen zweiten Ultimaker in Magdeburg! Ich studiere hier Industrial Design, wobei ein 3D-Drucker wirklich Gold wert ist und benutze meinen Ultimaker daher beinahe täglich für meine Entwürfe. Grüße!

The new Cura engine has improved my printquality in many ways and has speed up the overall printtime in most cases! =) But I have one feature request though: The setting for: retraction will be enabled on all moves. With this setting not available the top areas are scarred with pla that ozzed out of the nozzle and hollow objects are filled with strings. Will that feature return in Cura 13.06.x?

I'm currently using Cura 13.06.3 on windows and I'm impressed by the progress made already! Normaly I use Ubuntu, but Cura 13.06.3 isn't working on linux at the moment so I 'had' to switch to windows to test the new versions.... If I start Cura 13.06.3 under Ubuntu 13.04, installed with the .deb installer from software.ultimaker.com Cura opens but the 3D view is blank and I get this output: Traceback (most recent call last): File "/usr/share/cura/Cura/gui/util/openglGui.py", line 185, in _OnGuiMouseDown self.OnMouseDown(e) File "/usr/share/cura/Cura/gui/sceneView.py", line 582, in OnMouseDown self._mouseClick3DPos = self._mouse3Dpos AttributeError: 'SceneView' object has no attribute '_mouse3Dpos' Closing down (python:22828): LIBDBUSMENU-GLIB-WARNING **: Trying to remove a child that doesn't believe we're its parent.

Das mit den unterschiedlichen Faktoren kann ich nur bestätigen. Ich habe zum Beispiel Filament von einigen Herstellern getestet und bei fast jedem muss ich eine andere Temperatur einstellen, um optimale Ergebnisse zu bekommen. Einige mussten auf fast 225° aufgeheizt werden um gescheit gefördert werden zu können und andere begnügen sich schon mit ca.180°. Ist zwar ein krasses Beispiel, ist mir aber alles schon passiert.

Now ist works!! xD I think Daid was right when he said that the promblem must have been on the OpenGL side of things. I just downloaded the newest Driver from Intel, installed it and now both versions of Cura start like normal! =)

I used the versions from http://software.ultimaker.com/ The next step I will try is to use the version from github.

Unfortunatly the Output.txt is empty in both cases... Now it says: python.exe isn't working anymore! I even installed the newest versions of python from the website and always the same error. When I start the python.exe in the cura install directory python is working...

On first start, the first start wizard opened like nowmal and I was able to make all the Settings. Just after that the main window of cura didn't appear. I don't know if this hepls by tracking the error...

Hi there, I just tried to install cura on my new Surface Pro, but it gets stuck at the splash Screen. I tried to install 13.04, which just gets stuck at the splash Screen without any notification why and I also tried the new 13.06.2 which gives me the error: pythonw.exe does not react anymore. Has this error something to do with Windows 8 ore the Surface? I don't think that it is because of the grafics Card. The Surface pro got the HD4000 from Intel... Is there someone with the same Problem or knows how to fix this? Thanks in advance!

Ah OK. I went here: https://launchpad.net/ubuntu/+source/pyopengl and downloaded the .deb of version 3.0.0-0ubuntu1 for the Lucid Lynx https://launchpad.net/ubuntu/+archive/primary/+files/python-opengl_3.0.0-0ubuntu1_all.deb Now everything works again! Maybe this is helpful for users with the same problem. Thanks Daid for the info! =)

I had to make a completely new installation of linux because of some issues. Now when I do everything like bevore to run cura, it hangs at the splash screen and cura won't open. When I start cura through the terminal I get this output: lukas@workstation:~$ cura Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/wx-2.8-gtk2-unicode/wx/_core.py", line 14665, in <lambda> lambda event: event.callable(*event.args, **event.kw) ) File "/usr/share/cura/Cura/gui/splashScreen.py", line 16, in DoCallback self.callback() File "/usr/share/cura/Cura/gui/app.py", line 39, in afterSplashCallback from Cura.gui import mainWindow File "/usr/share/cura/Cura/gui/mainWindow.py", line 9, in <module> from Cura.gui import preview3d File "/usr/share/cura/Cura/gui/preview3d.py", line 15, in <module> from OpenGL.GLU import * File "/usr/lib/python2.7/dist-packages/OpenGL/GLU/__init__.py", line 4, in <module> from OpenGL.raw.GLU import * File "/usr/lib/python2.7/dist-packages/OpenGL/raw/GLU/__init__.py", line 6, in <module> from OpenGL.raw.GLU.constants import * File "/usr/lib/python2.7/dist-packages/OpenGL/raw/GLU/constants.py", line 7, in <module> from OpenGL import platform, arrays File "/usr/lib/python2.7/dist-packages/OpenGL/arrays/__init__.py", line 22, in <module> formathandler.FormatHandler.loadAll() File "/usr/lib/python2.7/dist-packages/OpenGL/arrays/formathandler.py", line 37, in loadAll cls.loadPlugin( entrypoint ) File "/usr/lib/python2.7/dist-packages/OpenGL/arrays/formathandler.py", line 57, in loadPlugin handler = plugin_class() File "numpy_formathandler.pyx", line 30, in OpenGL_accelerate.numpy_formathandler.NumpyHandler.__init__ (src/numpy_formathandler.c:1195) AttributeError: 'module' object has no attribute '_configflags' What have I done wrong this time? And what can I do to fix this? Thanks in advance!

hello snowygrouch, since you succesfully build your own dual extruder I would like to ask you from where did you get the second little pcb on top of the extruder for connecting the second termistor? Did you get it from ultimaker directly or did you make a homemade workaround for that?

Hallo alle zusammen, ich interessiere mich für einen zweiten Extruder und würde mir diesen gerne selber an den Drucker bauen, da es ja von Ultimaker selbst noch kein Set dafür gibt. Nun bekommt man im Shop schon einige essentiel wichtige Teile dafür wie die hotEnd v2 Teile und anderes. Was ich dort aber nicht finde, ist der Motor für den feeder, der stepper-driver für den Motor und die kleine Platine, welche auf den Druckkopf geschraubt wird um den Termistor anzuschließen. Weiß vielleicht jemand von euch, wo man diese Teile sonst kaufen kann? Bin für jede Hilfe äußerst dankbar! :-P
