@Titus if you win the kit I'll be happy to trade it for 7 spools of filament

If your in a hurry, did you check Ultimaker's US manufacturing partner? no idea if they ship to Canada at a reasonable price though... http://fbrc8.com/

@sandervG I like this contest! I assume we are allowed to alter the robot.... can you provide the .step file?

real creative people will be able to upgrade there UMO with the kit

not sure I understand the problem, i assume you've seen this?

Just throwing 2 fixed nozzles in your Ultimaker will not work, save yourself the trouble. There are a ways to make it work.. but complicated.... read more here; https://ultimaker.com/en/community/10657-a-different-multi-extrusion-approach-um-tool-printhead-changer https://ultimaker.com/en/community/17656-ultimaker-2-dual-extruder-einstellen?page=1

agree, let's wait until he shares some photo's .....

I would really advice to stick with the + feeder, and solve the issue... it's just so much more powerful than the direct drive feeder. I agree it's nice to be able to see the filament, but for me it's not enough of a benefit to go back to the direct drive....

with such a bold statement it would be nice if you could elaborate on what you think is wrong with the + feeder... and how you want it fixed.... and maybe share a picture if anything broke?

http://support.3dverkstan.se/article/64-disassembly-of-the-ultimaker-2-plus-feeder It's not to hard to just open it and see if something is wrong.

Nice! like to see a video when it's done.

it's looking like a million dollars https://www.youmagine.com/designs/nozzle-ring-box

Try printing slower, with that layerheight+nozzle size+temp your speed is just to high. Keep infill speed and print speed about the same. Assuming your on a default Ultimaker hot-end you probably don't want to go much hotter.

On the discounted ones I agree... but besides that I like the new 2+ feeder, I can now use the last bits of the spool with no issue.... Also I'm now back to the original plastic spoolholder i.s.o. the low friqtion one with bearings, which caused some spools to spontaniously unwinde making a mess... sometimes a bit of friction is a good thing... I think the original UM2 needed messing with it, I never understood people who stayed with the original feeder.

3dsolex.com you find a list of resellers on this site... E3d-online.com the v6 nozzles are ok for the olsson block. Out of my head... I think it's standard m6 thread...

cool!

Ah, I just asked in the wrong place.... can you provide instructions on how to unistall the old beta's completely? I tried ccleaner but was never able to get a clean install, always kept the old test profiles....

Yeah, very good that all spare parts are easy to order like this! Let you're collegae also check pricing think I saw a 10 pack bearings for around 1 euro ....

I don't think this is a Cura thing, just tried 2mm layers, the gcode seems to be just fine (also checked in S3D) could it be some kind of limit in the firmware of your printer?

Don't think this has anything to do with printing off the roll, it's really a physical thing. In this case it was faberdashery, kept in the original seal-bag. Still it became very brittle. I have never had it with colorfabb, maybe because it's softer in general...

and maybe check you gantry height in cura v.s. you physical gantry height, you would not be the first with an knocked-over item around 50mm high... cura has had different default heights over the years as the physical height in the UM2 also changed. more on this; https://ultimaker.com/en/community/18265-mastering-your-gantry-height

I had almost forgotten about the spool of super brittle faberdashery I had 'rejuvenated' about 3 months ago. The spool has been sitting on my workbench unpacked since. I printed with it yesterday and it worked. It's still pretty ok after 3 months, not to brittle, better than it was before the heating. There is a huge amount of tension in the material, I think with the "old" feeder it would have been a problem, comparable with printing the last filament on a spool. With the new UM2+ feeder it printed ok. So it actually works... but it's easier not to buy to much filament at a time, and don't let it get to old...

congratulation @dbrgn !!!! good luck with your upgrade, I'm pretty sure you'll like the new feeder...

you'll find it here, scroll down this page; https://github.com/Ultimaker/Ultimaker2Marlin

In the classic Cura you need to lower these values in machine settings to virtually make the head smaller; In the new cura beta, that will probably go public this week, there's no machine settings gui so you need to change it in the .json file for your machine (also here I would advice to first create and rename a new machine specially for this purpose). On a windows machine you find the file here; C:\Program Files\Cura 2.1\resources\machines
