The result of our #workshop   "Making for Everybody".

After the movie "Maker" was shown on #crossroadsfestival (http://crossroads-festival.org/de/programm/uebersicht2015) last friday, we invited everyone to come by the next day and make something within 2 hours at realraum. Besides showing off our S1 bio lab #OLGA , we designed, lasercut and assembled this nice and useful box with our visitors.

of course, this is an open-source box:

Temporary out of service. All the white smoke needs to be collected and put back in.

Yet another "Ah das hamma glei" meeting produced a computer controllable light for the kitchen area and NFC tags for wifi and the display window. The kiosk display was fixed too.

We just got a generous donation of about 10kg of well sorted wool and yarn, free for everybody. Now what to do with it (or where to store it). Guess someone will have to give a #crafting talk/workshop soon :-)

Jampo built a Stirling engine. So simple, yet so irresistible cool.

Thursday we unboxed our highly anticipated TAZ4 #3DPrinter, which we won as part of the #LulzBot 4th Annual Hackerspace Giveaway.

It rulez !! :-)

We have a very coloured history when it comes to 3D printing. Ever since we ordered the first parts for our self-built RepRap Mendel years ago, 3D printing was something you did not mention easily at realraum.

The RepRap was built, rebuilt, adjusted, taken apart, modified and hacked, again and again. All with mixed success.
While we did learn a lot about 3D printers in the process, likely spent more than 300 man hours on it and even wrote a big TeaCup firmware patch, the thing probably only ever spent a sum total of 2 weeks out of 5 years in a state where it could actually print, badly!
Most of the time however, nobody knew who last took apart what or was planning to improve which thing next.

Then came the MakiBox. Co-sponsored by one of our founding members (who resided in Hong-Kong at the time and co-founded DimSumLabs there)
Always on a tight budget, this first-of-the-line production model seemed the perfect way to finally make 3D printing a reality here at realraum.
Especially since said founding member was sponsoring it. In its defence can be said, that, frail as the design was, it did actually print in the beginning. Unfortunately that state would not hold very long.
We then decided not to review the MakiBox, as we were missing the words to describe just how crappy it really was.

Again, 3D printing was not mentioned at realraum for about a year.

Finally, along comes the Lulzbot TAZ4.

After just a few days it may be a bit much to say "Lulzbot rescued 3D printing for us", but that's about what it feels like right now.

It has a large print area and is capable of very fine and precise prints. It follows all best-practices I've ever read about
making 3D printers. E.g. it has a heated glass-surface which is perfect for PLA. Beyond that, you might even accuse Lulzbot of over-engineering. Looking at the industrial grade cable connectors, screws, bearings and shaft couplings, you
know they didn't skimp on the parts. Next to that is ships with a bag of quality tools which even includes a jar for mixing ABS and Acetone.

Our first test prints came out very well. Even when stress-testing with our crappy old PLA roll, the prints came out very nice.
The nice fan and air-guide works just as expected and overhangs printed without problems. Using rafts, even delicate and complex prints with little surface area came out fine.

To show off the printing process (and experiment with gstreamer), we mounted a webcam on the platform, the resulting time-lapse videos can be found in the gallery.

It does have its hard edges, but this printer is not meant to be super-user-friendly and DAU-resistant. Instead it is hackable, open-source and a precise straight-forward work-horse.
Just how we like it! Despite our hack-at-it attitude, we did appreciated the big and surprisingly useful user-manual as well as the handy illustrated first-steps flyer.

All in all, the printer gives manages be at once a highly professional machine as well as a matured hackable open source project.

Of course, it would not be bitchy us, if we didn't find anything that could be improved.
Most of that can be traced to the firmware: The sampling of the rotary encoder for once feels sluggish and imprecise even though the encoder itself is high-quality.
We also wonder if the forces reset on SDcard change and usb-cable plugin is really necessary. Finally, it's OK that the printer does not print from SDcard when
still connected by USB, but it could display a warning instead of just plainly doing nothing after one selects "start". Also the resonance frequencies of the
printer could have been measured and the firmware modified so it would then avoid certain of those speeds and direction changes. Since it's all just software, we may actually do something about that in the future :-)
On the hardware side, we noticed that the power supply's cooling fan would still run long (hours) after the printer had been switched off. (Note: the only big off switch is on the DC voltage side of the printer).
Not sure if that fan actually ever stops.

All that (and on the bitchy side: the fact that it's just that) really really shows just how much experience and know-how (hard won over the years of DIY 3D printing I'm sure) went into making the TAZ 3D Printer.
Thanks #LuzlBot !!

Yippii Yipii Hacking Yeah ;-)
realraum participated in the 4th annual #luzlbot hackerspace giveway (https://www.lulzbot.com/content/fourth-annual-lulzbot-hackerspace-giveaway) and .. WE WON :-) A nice and shiny LulzBot Mini!

Since our bad experiences with the MakiBox and our permanently under construction RepRap we are really looking forward to finally having a modern, working and reliable 3D Printer at realraum.

All those cool projects on hold until now... as soon as the #LuzBot MIni arrives in the post, they are a GO ! ;-)
