Printing in Wood. Which feels more like cardboard after it's printed. But it's supposed to harden after a while.

The Ultimaker IS on the photo. But not showing the hotend. It's the stock hotend V2, twice, next to eachother. With the fan on front. However, this isn't mounted properly yet, as the fan shroud is melting. Disassabling and reassembling with the dual-head took me about a day. It's crowded and it's easy to make a mistake. (Note that it's a side project of mine. It's not ready for production, so do not ask if/when we will sell it. As we cannot tell)

https://groups.google.com/d/msg/ultimak ... Sm2Nir1fkJ I've uploaded a pre-release of 12.10 for Mac and Windows. Read that post for details.

Most likely you are under-extruding. Less filament is coming out of the nozzle then intended. As your tops/bottoms are also not filled fully. Could be your extruder drive slipping. Do you have a V3 bolt and the new bertho extruder upgrade?

I got 750g of this stuff now. So time to play with it! Please please, do not hack in cura_sf, it's a horrible mess. It's better to make a stand-alone post-processing script, which would be better for future compatibility. You can run this post processing script from SF, but we could also run it from Cura. The less features that depend on SF, the better.

At Ultimaker we have the world in our hands now!

Yes, this is not software related. Check your electronics, there are "jumpers" on this. The Z motor should have 1 jumper less connected then the other steppers. (check with the photo of the electronics on the wiki, wiki fails to load here at the moment (in the train))

Experiment with it, and let me know what works properly for you. You can use any value you want

It's the minimal layer time, which is currently 10 seconds, combined with the minimal feedrate. Both still need some tweaking for the correct settings for these kinds of prints.

I commented on then through PM, so let me add my comments here. I think the first bunch are a bit too 80s / NASA. I like the last one. But whatever it will be, I have to talk with people here at UM. We might just use the robot as icon but that one doesn't scale very well to 16x16 and 24x24

We flipped a printer here yesterday, which helps in getting the production robots of the platform, but the prints look exactly the same. There is still the bit of the standard oozing between the horns.

Not really, some communication errors with the USB-Serial are expected and Cura checks and compensates for these communication errors.

Yes, it buffers the entire file, so you can override it during printing.

Yes, very soon

We test almost all our PLA. Only our white needs a slightly higher temperature, the we print at 210C. We notice more slight variations between machines then between PLA.

Never EVER claim you are the first in anything: http://www.meshmixer.com/

Most tweaking with settings is about changing the print quality from good to awesome. The biggest problem I see, on the forums, groups and in person, is that people have mechanical issues (wrong assembly) and try to fix that the wrong way, with setting changes for example.

I'll have to report some delay on the dual extrusion. I tried to assemble it in a machine here, and it does not fully fit. The head with two V2 hotends and the fan cannot fit together.

It looks nice, it feels nice and it smells nice.

Care to share a photo of your hotend? It should NOT look like this: https://ultimaker.googlegroups.com/atta ... w=1&part=3 I've seen 2 cases of the hotend being assembled like this, and both times it causes 80% blockage in the hotend. It should look like this: http://www.flickr.com/photos/ultimaker/ ... /lightbox/ With no threads showing.

People have printed at 0.01 and 0.02 In my experiance the quality doesn't seem to improve after 0.05

That could be pushing it, but the only way to know for sure is to try.

Possible causes: - Motor power - Dirty rods that need oil (worked wonders for my machine after lots of moving) - Axes are not square (was the problem with most machines that came back from NY makerfair) - Small belts are jumping over pullies, but you'll get bad prints before this. - A Tesla-coil on the same power strip.

It's indeed our first self-printed part in the kit. We actually print them at the UM HQ. I'll ask around about the open-source status of the upgrade.
