Good to know about the room temperature! I was only printing small parts recently but I'll keep this in mind. This thread is really incredibly helpful for newbies :-)

I didn't change the orientation and my UM1 doesn't have a second fan. I really don't know why it finally worked but it did! Printing low and slow probably did it (or maybe the Cura 14.03 upgrade? the room temperature of only 16°C? the fact that it's friday?)... Anyway, I used the Ultimaker Bronze PLA filament (so shiny!) and printed at 195°C, 30 mm/s, top/bottom thickness 0.8mm, standard settings otherwise.

It's just the Ultimaker Robot but I'm so happy that I finally managed to print the right ear correctly that I'm doing a https://31.media.tumblr.com/tumblr_lk359tXZNP1qh9061o1_100.gif :-) I actually wouldn't have printed it if the model hadn't loaded automatically after updating Cura and I needed a test print anyway. As far as I'm concerned Cura 14.03 is magical :-) (And maybe figuring out the right parameters for the bronze PLA helped, too.)

I don't have a suggestion who you should approach but I'd like to add that you shouldn't approach Conrad Electronics. I've never had any good customer experiences at their stores. Their staff just doesn't seem to be very well trained or interested in answering questions and selling things. The stores are very unwelcoming by design and while they sell a lot of cool things they also sell a lot of junk, too. I only shop there if I need something immediately or the parts are so cheap that shipping charges would more than double the price. A friend of mine who is interested in 3D printing went to the store in Hannover to check out their printers and described the presentation as lackadaisical- there was no one even remotely passionate about 3D printing or able to answer basic questions about the printers.

I'm using the Ultimaker Original that doesn't have a heated bed (yet). But I found that the filament sticks extremely well to the unheated bed. It was quite difficult to remove it, something I hadn't experienced before.

I've found optimal print temperatures can vary a lot. I'm currently experimenting with the Ultimaker Bronze PLA filament. So far it seems that 200°C is the best temperature (at 50 mm/s print speed, 0,1mm layer height). Might even go lower than that. Anything over 210°C produces really ugly prints. However, for the Ultimate Blue PLA (the light blue one) needs to be printed at 220°-230°.

There are several online libraries for small parts like nuts & bolts, e.g. TracePartsOnline . They provide CAD data in several formats but you might need some kind of CAD program to convert it to stl files. As an engineering student, I used Partcommunity for my design projects because of their great range of manufacturers' catalogs but it is fairly overwhelming at first and I read in the terms of service that you shouldn't use their CAD files to duplicate the parts. Oh well.

Die Firmware für den Ultimaker (Marlin) wird beim ersten Start von Cura installiert (https://www.ultimaker.com/pages/our-software). Die Open Source-Dateien findest du hier: Cura bei Github: https://github.com/daid/Cura Marlin bei Github: https://github.com/ErikZalm/Marlin

Well, I think it depends on the scope of the meetup. Do you want an informal meetup with 10-20 people or a bigger event? Do you know sponsors who'd like to get involved? The Festung is a very impressive location indeed! From what I gathered from the Festung Königstein website (http://www.festung.de/). I assume this means that we won't get electricity for 20-30 printers for free but you could try asking anyway. :smile:

Oh, I didn't realize there was a difference in the orientation of the bed. Well, that's one error that's quickly fixed! Thank you both for your valuable comments. I feel much better knowing that it's only important that the angles are square (which they are). Time to stop tinkering and learn about the software settings! I'll also try some wider painter's tape.

A few days ago I assembled an Ultimaker Original and successfully made a few prints. However, I'm not quite sure how to interpret the test print that the bed leveling wizard made. I think the bed is leveled well enough (bottom of my printed objects looks fine) but the printed lines do not run parallel to the sides of the printing bed as I expected. Is this caused by a misalignment of the pulleys? How is the test print supposed to look? Furthermore, I'm confused that there's a 2 cm offset to the right. Is this normal? I don't know how to access the GCode of the test print so I don't know where the lines are supposed to be. Otherwise I'm pretty happy with the print results. This robot is printed with the default Cura quick print profile for normal quality print. (PLA 220°C) (Except for the ears but this might be due to opening a window. it's currently 0°C outside.)

Hallo, ich lebe in Ilmenau (in der Nähe von Erfurt). Ich habe letzten Sonntag meinen Ultimaker 1 fertig gebaut und bin sehr begeistert! Bei einem Usertreffen wäre ich dabei. Bier, (Thüringer! :-P) Bratwurst und 3D-Druck klingt gut.

I recently bought a Ulticontroller, too (December 2013). Both of my cables are the same length (about 330 mm) and the Ulticontroller fits easily on the front of the Ultimaker. I guess you were sent a wrong cable. Regarding the fan duct: My kit didn't include a different fan duct either. Maybe there's a mistake in the Wiki or it refers to an older kit?
