BeagleBone Green?

Interesting Beaglebone news: In one of SeeedStudio‘s latest blogposts by Eddie Hu about RaspberryPi alternatives there is a competitive analysis with an interesting item. There seems to be a plan within SeeedStudio to release an alternative BeagleBone with Grove sensor connectors, with the (code)name “Beaglebone Green”.

BeagleBoneGreen Announcement?

And for better visibility I will zoom in:
Zoomed-in text

The Grove line of products is a set of breakout boards with standard connectors to Analog, Digital, I2C or UART. Most of these tools are sensors and the add-on boards to Arduino, Raspberry Pi, and other small computers. Their site already lists 156 products.

Technically, one of the best boards for the purpose of using a lot of their sensors at the same time is the BeagleBone Black. Their board has specifically added things like analog i/o and real-time processors so no extra Arduino is necessary, like on the Raspberry for instance. The only problem is the intimidating expansion ports that most of the time just work as side bumpers. They do that job very well by the way :)

The people at SeedStudio already made a Grove Cape for the BBB, but that is almost as big as the BBB itself, and seems not to adhere to the cape instructions as it has no EEPROM to provide setup info. It also has only two Analog(dual) ports, two UART ports, and two I2C ports. As most Grove sensors only use one of the analog ports, it can get full rather quickly, unless you mod the cables yourself. The digital ports are easily reachable from the GPIO itself, but that is beside the point with Grove modules. All that could be solved by a BB version with a lot of adapters built-in.

So SeeedStudio adapting a BeagleBone to become extra Grove friendly would be a huge boost to the usability for hackers prototyping new ideas with their system. Add to that the possibility that people could add a lot of tutorials to that base, moving the Grove Wiki documentation from mostly Arduino based, to BeagleBone Green based. As prices for ARM based development boards keep falling, the competition to dethrone Arduino seems to be mounting.

We asked about it on the blog yesterday, the post was moderated, but no more info was given. Maybe more will be known soon, there is a mail gone out to ask for more info.
We will also ask someone within the BeagleBone project for more info.

I could not find more info on search engines, maybe you all could do better?

I’m looking forward to it :)

Update:(2015-01-29) I got some answers from the SeeedStudio people, they confirm they are working with TI on the a BeagleBoard Green, but haven’t got approval yet. They are sample testing now, and hope to sell the boards in May of 2015. I have asked for more info, but there was no reply yet (two weeks, so chances are low).
The people from Beagle/Circuitco haven’t replied yet (also two weeks ago) or acknowledged receipt of my mail. Maybe I should do a follow-up mail?

Update 2:(2015-02-04) I met someone from BeagleBoard.org on IRC, and he did not want to “give details they aren’t giving about their product”, but explained there are other boards in preparation based on non-BeagleBone designs, and that “BeagleBoard.org is very interested in having people clone the design and trying to help promote those clones”.

“The design is open, so ultimately they can do what they want in terms of product development. Details around branding are still being worked out.” So for now there is no decision on using the BeagleBone name on non-Beagle designs. The “BeagleBone compliant” badge would be only for direct clones, so other designs would need a different badge. For more on the organization’s view on the BeagleBone design, see the talk (video) from Jason Kirdner of BeagleBoard.org during the OHS Summit 2014 in Rome.

As an example of their cooperations he referred to the upcoming Arduino Tre a cooperation with the Arduino team that should arrive soon, and also another board that is under development, the BBP, which seems to be a BeagleBone for Reprap, designed by Truby Zong. An eventual release date is still unclear.

As Truby describes it himself:
BBP BeagleBone 3D printer control board:
1GHZ AM335X
5 stepper motor drivers
3 MOSFETs for 2 extruders and 1 HPB
6 MOSFETs for Fans or LED strips
6 endstops

Also there is mention of a new board from BeagleBoard.org itself, the BeagleBone-X15 but that will be a very different design, also at a different price, certainly above $100. But also with lots of more extra’s :) It should arrive in the coming months.

More news when it happens. There surely is a lot happening on the BeagleBoard.org side of things. This update could have been a full post in itself!

Buildparty Düsseldorf Report

The build party was another big success, the 7 participant teams built themselves a brand new Reprap “Prusa i3“.
The people from GarageLab were very helpful, and have a nice space to work at. We used the coworking space rooms to do our building. Thanks to Daniel Bruns and Carsten Born, they helped out a lot. Also thanks to Lab maintainer Axel Ganz for helping setting things up, and Yvonne Firdaus, the Coworking Space / GarageLab owner.

We had a lot of help from the community people attending, there is a lot of information to be had when you are in a room with Kliment Yanev, Josef Prusa, Joachim Glauche, Nathan Zadoks and Ruben Lubbes. Also there was a group of locals working on their Reprap’s in the fablab itself, there were a few machines from our earlier parties present. It was nice seeing them improve the machines, and using them a lot.

We built a reasonably new model, the Prusa i3, and it is a big improvement in building the machine. That was also one of the reasons the machines are so quick to be in use, most of the people were printing at the start of sunday afternoon, and everyone printed a model that looked pretty nice.

The i3 is different from the model we used in our previous courses because it now uses a wooden box-frame that is very stiff, stable, and easy to build. Also it moves the motors to the bottom of the machine, so the Z-axis does not hang from the motors anymore. Also the amount of noise the machine makes is lower, and cable management is improved. Also the spool mount is integrated on top of the machine.This makes the i3 a very good option to build as your next Reprap. The design is still in developement, so for now the build info is still incomplete.

We did most of the building in the first day, and were mostly doing the last part of the electronic setup on sunday morning. The electronics we used were ReprapDiscount RAMPS system, and jhead hotends. Most of the other parts were sourced at ReprapSource. Both of these performed very well. Around lunch most of the people were getting ready to print, and we made some cool models in the afternoon.

Then we also did some presentations on the history of the project, getting help from the community, and some info on how to do 3D modelling with OpenSCAD.

2nd print on a newly built Reprap

Just look at this 7,4cm tall Statue of Liberty, it is not very visible because of the background and transparent material, but the crown is really very nice. I hope we will get more pictures of that soon.

2nd print of the new Reprap, different angle

Some pictures are already available here, but i hope to see more soon.

And this time we managed to do a group picture again, so here it is!

There was even an interview done with me by Josef Prusa in his series of interviews, see it here

And finally: a timelapse of the build!

I would like to personally thank Axel Funke, for driving me home afterward although he had to go a totally different direction to get home himself!

We will be doing more of these buildparties, so if you want to organise one in your town or hackerspace, contact us!

Prusa interviews me in Düsseldorf

During the Reprap BuildParty in Düsseldorf Josef Prusa did an interview with me in his series of interviews about Reprap and the community, and he posted it to Youtube.

In the interview we talk about me finding the project, collecting reprap memorabilia, my island promotion of Reprap, the history of IkMaak, why the courses are organised, and the way progress in the project is made. I’m rambling a bit, but i did not prepare for the video, so have fun!

The FrankenBot project is also mentioned, if you want to join in with a part for that, get the part from the list, do anything you like with the design, as long as it is still functional, print it out, sign it, add some documentation, and send it to me! Contact me for more info.
I hope you like the interview, there’s more where they came from. They are featured after the break.

Build Party Cologne Report

We have been having a great time on the first day of the course, doing almost all of the construction of the machines in one day. The Coworking Space Cologne/DingFabrik is where the event is being held is very nice, and very active, they organise meetings on friday evening, so come by when you are near!

All the participants made the whole machine frame, hotend and other electronics, including hotend and heatbed, and even endstops. We mounted 2 already, only needing to attach the Z axis Hall-0 Endstops on day 2.

This is a new record for us! First time builders making a machine almost entirely on one day! :) We tried a new order of putting the parts together, so the difficult parts were done first, and then the frame would be setup as late in the process as possible. This way the progress is easyer to see, and you dont setup things wrong first, only to repair them later.

We have made a lot of pictures, more are on their way from the participants themselves, and others. First set is in: Thomas Feldmann’s pics

We used different hotends this time, with IRC resident “jreifsnyderb” sponsoring hotends. We have used his J-Head Mk III-B, instead of the standard MakerGear ones we normally use in our build party’s. The buildup of these hotends is very easy, as they also come with groovemount, and are almost fully assembled.

The second day was a bit more difficult, we spent most of it installing the software, as almost every machine was running a different OS. After that we could print some parts on every machine, and i think all people left with the feeling they had a good start in the world of RepRaps. We also built a RepRap for use in the DingFabrik, so they will have one there from now on.

Also we had a visit from Fabienne, who will build one of our kits soon, and hopefully be printing out parts in no time :)

We will update this post soon to add the software package we used to provide the people with during the course. We used the Marlin Firmware on the bot, and Pronterface with Slic3r on the PC’s.

Cartesio

Cartesio is a printed multi-purpose desktop CNC machine, with a working space of 300x200x100mm(X,Y,Z).
The machine is designed to hold multiple tools at its toolhead.
This way one could connect a mill and/or a 3Dprint extruder and/or ….

Cartesio is constructed from lightweight aluminium extruded profiles.
These give the machine a very rigid construction, and alow for easy configuration of the machine.
So if you want to change anything, i.g. the Z axis to a much longer configuration, it can be done very easily.

The axis are powered by 3 NEMA23 steppers.
These drive trapezoidal spindles that move 3mm per rotation.
With these spindles you can generate a huge amount of power.
The max feedrates, are 2400mm/min for X and Y, and 660mm/min for Z.

The workspace only moves in Z-axis direction, and is supported on all 4 sides.
This gives a very rigid workplane that does not move fast in X or Y direction.
This is done, so that larger objects will not have stress/torque from (de)acceleration.

The “gantry” type X and Y-axis make sure that a wide variaty of tools can be mounted to the toolholder.
This kind of setup can result in a toolchanger in the future.
At the moment a proxxon engraving tool (thankfully donated by Hegner) is mounted to the toolhead, together with the new 3Dprint Extruder.

RepRap improvements I – Hall-0 endstop

We would like to tell about some of the improvements we and others have made on the “traditional” RepRap design (traditional being last week?).
That is why we will start this series. So here we go!

One of the problems we have found while operating the machines here is the problem that it is difficult to get the Z height precisely right. While using opto or mechanical endstops you also run into different problems like bumping out of position or light influence. That is why our teammember Jos from Mauk.CC designed the Hall-O endstops. It is a contactless magnetic sensor, with a much higher precision than normal endstops. This enables us to set this once, and then forget about it untill the next retrofit of improvements.

These endstops can be used as a drop-in replacement of other endstops, in all RepRap variants, and all other (cartesian) systems that need the precision. See the adapted endstop mount for easy mounting. They can be used on RAMPS, Sanguinololu and more. They make most sense on the Z axis on a RepRap, but for other machines this could vary, depending on the needed precision on these machines.

Hall-0 Endstop

It measures the distance to the magnet, so it can be set to trigger digitally at a set distance from the endstop, between 2-4mm with the standard magnet. The distance can be configured by the trimpot. This way it will not interfere with the movement or placement of the endstop, and it will keep in place without problems. It could also be used as a analog measurement device, but the current hardware and firmware used by the project do not allow for that yet. The endstop contains the endstop, a mounting cable, and a magnet, enough to get your Z height precisely defined. We have gotten a lot of them in the world already, so maybe we will see some reviews by others soon.

As we would like to see this into the hands of as many RepRappers as possible we have made them also available via our site, mail us at info at ikmaak.nl and we will inform you of the cost of sending one or more. The price is 9 euro excluding postage. If you want to buy them in bulk please drop us a line as well :)

RepRap bijeenkomst 15 oktober

Groepsfoto 23-25 september RepRap Buildparty

Na onze geslaagde cursus in september hebben wij met de deelnemers afgesproken om samen met alle mensen nog een middag te houden om het verdere gebruik van de RepRap nog eens door te nemen. Hiervoor is zaterdag de 15e gekozen.

Ook de mensen die de eerste cursus meededen zijn hiervoor natuurlijk uitgenodigd. Er komen weer een heel aantal mensen uit de community, zoals o.a. Kliment, Joachim, Nathan, Jos, ik, en meer. Het belooft een gezellige meeting te worden.

We willen aan de technische kant vragen beantwoorden, meer vertellen over de software, en de mogelijkheden die de community biedt om samen te werken belichten. Verder is het een goede mogelijkheid om ervaringen onder elkaar uit te wisselen.

De plaats is weer in het Fablab ZuidLimburg, in de Hoenderstraat 3 te Maastricht. Kom gerust ook, en neem je RepRap mee. De meeting is komende zaterdag de 15e, van 15 uur tot 18 uur.

Zijn er nog onderdelen die men nodig heeft of graag wil hebben, geef dit dan van tevoren door, dan zorg ik dat deze aanwezig zijn. Ik probeer in ieder geval om diverse dingen aanwezig te hebben, om eventuele reparaties of upgrades te kunnen doen.
