Hi Paul, congratulations, welcome to the community!
The regular build instructions are meant for single extrusion.
If you have the time and patience, i would recommend to get familiar with single extrusion first as this
will give you better results at start and it is the basic set up you will get familiar with.
Once you get the hang of it and you know your way around Cura, i would add the dual extrusion.
The downside is, that it requires some patience (but single extrusion is no less fun, especially in the beginning i must add), and it would mean you have to take the print head apart again to install dual extrusion.
It may not be the most convenient path to follow, but i think it will be the most motivating and rewarding path.
Of course, it is totally up to you
In any way I/we are available for guidance. -
If you are just about to start printing (with an Ultimaker) i would recommend to start with single extrusion first.
It is a fun process to get to know the machine and learn how to use it, but it is a process.
My recommendation is that it is easier to learn printing with 1 extruder, and get familiar with Cura.
Because dual extrusion is still experimental it requires some tweaking, so get familiar with the basic set up first, then enhance your set up with dual extrusion.
At the moment support material is not yet supported by Cura, but dual colors is.
You can use it for anyway you please, but it would serve its cause if it involved 2 colors ;-)

nice video, well done

I agree, most likely the iron cover of your thermocouple started wearing off, and now it is reading the temperature just outside of the aluminum heater block, where it is slightly colder. Hence the lower temperature.
Have you recently had to disassemble your hot end, or remove the thermocouple by chance?
-
Not support it & didn't work for a while is the same in my book
But good to know it works now. Thanks!
-
The holes shouldn't have any room for adjusting, because this would result in room for play, and end in an inaccurate wobbly machine.
On rare occasions we have had a customer whose (for example) side panels had a slight deviation.
Usually this is recognized during or before the assembly, so it could be replaced by a new panel without to much efforts.
Of course i offer you this same solution if it turns out the frame has a deviation.
If you are in need of a new frame please contact me via support - homepage. I would be happy to help.
If it turns out the panels are fine and something needs/needed tweaking during assembly i would be happy to read about it here and offer you assistance.

You may also want to make your build platform 1cm smaller (Cura > Preferences > Max depth 195) if you intend to do
first run wizards. If you don't the 2nd nozzle will run over the 2 back screws.
That is not mandatory, but for some it can be interesting i think.
I am not sure, but is Netfabb supporting retraction? I know it didn't always support it, never actually heard they did but i can't imagine they haven't figured it out by now..
-
Hi Drayson,
I would also suggest to have some heavy guys push it down and tighten everything again.
Can you see if the right panel maybe has some off set?
If it does, and you are planning on disassembling it, we could also sent you a new right panel (although i can understand that would not be your most favorite option).
If you have never experienced difficulties during printing, you might also make the call to leave it like this and print some foot pads for your Ultimaker, and make the front right one a little bit thicker.
How is your printhead compared to the build platform?
-
Is it because of wipe, or a different feature? (or multiple).
It could be worth checking the latest version of Cura, i heard some good stories about it handling big (huge) files.
However, dual extrusion for support is not yet supported.
-
Lol, this reminds me of a topic i once saw.
Something about showing of your prints with your pet.
I believe Daid also had some pictures with his cat? :smile:
-
In the beginning i aaaaalways used Kisslicer, but now Cura has improved in the way it has i have never used it again.
Are there any reasons to look at KS again?
-
Hi Wupsje,
I have heard that tip before, and it is a good one. Thanks for sharing!
-
Are you working on windows or mac?
In any case you should use the latest version of Cura, which is 13.06.4 for windows.
In preferences you need to select 2 extruders.
You need to restart Cura, and upload new firmware to the Ultimaker.
When you are going to slice a model, you have to make sure to set a temperature to both hot ends.
Because with dual extrusion, you can still make single extrusion prints, so the option is available to leave 1 hot end disabled.
Are you sure you have connected the heater cables in the correct slots?
-
Have you measured your filament?
It rarely is 3mm, it usually is 2.85mm for example.
This makes a big difference in the extrusion.
Being 0.01mm is no biggie, but 0.2mm is a lot.
I would remeasure that first, changing shell thickness can also help but that probably won't be the key-factor.
-
I believe Owen means wall thickness.
You can also set this in Cura.
Can you make some screenshots of the settings you have been using?
-
I have my Ultimaker for almost over a year and it has been used quite a lot.
I never had issues with motors getting loose very easy, or screw holes wearing off.
I do have washers under the screws, maybe that is a good idea if you don't have it already.
Except for the previous mentioned tips, you could also have checked your axis for alignment.
If it would be off, or the pulleys would not be parallel with the axis, this could also create more resistant when
the printhead will approach the frame/sides.
-
There are 4 screws in the Z-coupler.
If you remove them you should be able to lift the threaded Z axis without friction.
You will have to screw the axis out of its position, because of the nut that is in the Z-stage.
If this doesn't seem to work, could you post a small video illustrating your situation / efforts?
Thank you,
-
haha i am glad to hear everything arrived in a good condition!
Enjoy the assembly and feel free to keep us updated with your progress, and especially your first prints!
By the way, where can i find the video for unboxing?
-
You should probably also guide the cooling air more towards your print with adjustable part on your fanduct, instead of straight down.
As you can hopefully see on the picture, the fanduct is now guiding the air straight down.
Try to bend this adjustable part more upwards, so that by eye the air would pass right under the nozzle.
Lowering the temp to 200°C sounds like a good tip as well.
Have you used a default profile with your cube, or did you start tweaking the settings in cura right away?
Can you tell us some more about the settings you have used?
-
I also think this looks like a Z seam.
As you are using a rather older version of Cura (13.03), didn't you calibrate Cura in a way Daid, that this was
hardly noticeable nowadays?
So i would suggest to download the latest Cura
-
Hi Drayson,
Could you add some pictures to illustrate your situation?
-
I thought i remembered another aluminum Ultimaker, right here in the Netherlands, Rotterdam.
Took me some research, but i found them:
I saw this video once, haven't really been in touch with them so i am not aware of their experiences with it.
Maybe you could reach out to them for some first hand experiences.
-
I'm just ordered my dual kit !!!
Great, i am looking forward to see what you have made with it!
-
Hi CodeMaven, that is one part that comes with the injection molded-set that rev4 Ultimakers have.
You do not need it for Dual extrusion, however you do need to check if you are in need of the mounting aid or not.
Pictures are included in the shop to illustrate what i mean. (you can visit the shop if you made a pre-order).
For everyone else later on this week Dual Extrusion will be made available.
One or two extruders

A solution in his case could have been, make the printbed 1cm smaller.
We did not realize this, but we will set it straight with him.
If, like you say, people care about the 205, then they should be careful (avoid) the first run wizard in combination with dual extrusion. Besides that, there is nothing Daid can do (in Cura), because by adding a 2nd nozzle, this takes up space. Nothing you can do about that.
There are bugs in the dual extrusion pack though, it has been labeled experimental for a reason.
