    Toulouse HackerSpace Festival et 3d-printing-event fin mai

    in Français

    Posted

    Bonjour,

    THSF:

    http://thsf.tetalab.org

    Qu’es aquò ? Pour faire court, une rencontre qui brasse des gens venant d’horizons culturels et techniques très divers, autour de l’utilisation créative des technologies, leur appropriation et la compréhension des enjeux qu’elles suscitent.

    When ? 27/28/29 Mai 2012

    Where ? Tetalab / Mix'Art Myrys Toulouse / FR

    Et en plus long ça donne quoi ? A l’origine, il y a les hackerspaces, des laboratoires plus ou moins formels où tous ceux qui le désirent se regroupent sur des projets touchant à la science, aux technos, à l’art numérique et j’en passe. Ce rassemblement est l’occasion pour eux d’échanger sur leurs réalisations, leurs expériences avec tout/e/s.

    Concrètement, vous proposez quoi ? Conférences, ateliers, concerts et performances !

    Une série d’une dizaine de conférences qui vont du Faire soi-même ou DIY au hacking juridique, en passant par les réseaux sociaux alternatifs ou autres bizarreries... mais aussi des ateliers où vous êtes invités à venir fabriquer/bidouiller/tritouiller vos propres créations, à apprendre aussi... Les conférenciers nous viennent d’un peu partout en France mais aussi d'Italie et d’Espagne.

    Des performances artistiques, Video mapping, VJ, des installations et des concerts pour faire un bon mix d'art et de tech.

    Qui est derrière tout ça ? Mix'Art Myrys (célèbre et historique collectif artistique) et le Tetalab (hackerspace toulousain) s'associent pour créer un événement riche et surprenant !

    Et c'est cher ? Free as in free beer ;-)

    Noobie tutorial for starting with Ultimaker ?

    in UltiMaker 3D printers

    Posted

    From our last 3d-printing-event in Toulouse, I made this 8 steps ready-to-print manual:

    1. Download Arduino 1.0 -

    http://arduino.cc/en/Main/Software

    2. Dowload latest version of Marlin:

    https://github.com/ErikZalm/Marlin/zipball/Marlin_v1

    3. Upload Marlin on Ultimaker arduino mega 2560

    4. Download latest version of Cura:

    https://github.com/daid/Cura/downloads

    5. Download a STL model from

    http://thingiverse.com

    6. Open Cura (from start menu on Windows, or ./cura.sh in a Mac/Linux Terminal)

    7. Load the STL model in Cura, let the default parameters and "slice to gcode"

    8. Open Pronterface (from start menu on Windows, or ./pronterface.sh in a Mac/Linux Terminal), load the gcode file, preheat the extruder to 220º and print

    Problèmes d'impression

    in Français

    Posted

    Certains de tes problèmes semblent liés à l'utilisation de ReplicatorG, je te conseillerai de passer sous Cura afin d'avoir la même config sur windows et mac:

    Tu peux télécharger Cura RC2 sur cette page:

    https://github.com/daid/Cura/wiki

    Puis utiliser pronterface pour contrôler l'imprimante et envoyer le gcode.

    Pour l'ABS, il te faut un plateau chauffant pour que le plastique colle au bed, sinon ça ne collera jamais (c'est un des avantages du PLA sur l'ABS).

    Le problème de décalage du Z vient probablement du start.gcode, normalement la config par défaut dans Cura fonctionne correctement.

    blue tape replaced by polyimide tape

    in Third party products & modifications

    Posted

    Hi all,

    Because we're planning to print ABS and fit an hotbed on our Ultimaker, we've recently bought a big roll (33m x 10cm) of polyimide tape.

    It's the perfect replacement for the blue tape, objects stick perfectly to the bed (on the original bed until we fit the MK2 hotbed), and they unstick without much force.

    I was pretty annoyed during my latest blue-tape printings to clean the tape from the object and put back a piece of tape on the bed. Maybe our UM was not well adjusted, but I can really see the difference now.

    Is anyone else using polyimide? Have you had any problem with this kind of tape?

    Because we have so much of it (33meters, we need 40cm to fit the original bed, so it can fit 82 Ultimaker beds), we plan to make a kind of posting-chain:

    - we send the tape to someone

    - he/she roll it on its bed

    - he/she send it to someone else

    - we should be able to know where it is at a given time, and send it quickly to someone who needs it

    - bonus if we can print a box to fit the tape, and customize this box along the way :)

    What do you think about this? Who would like to participate?

    Have a nice day,

    Alex

    Hi Didero,

    Thanks for your feedback :)

    Unfortunatly, I'm still blocked on current issue compiling deuligne support on latest version of marlin.

    If you have any idea of where I could look, or if you could find someone to give me more advice about this issue, it might help for further investigation.

    You'll hear from it as soon as it's working properly :)

    Have a nice day,

    Alex

    Hi all,

    I've begin to re-implement the Deuligne on latest version of Marlin, the non-working code is available here:

    https://github.com/alx/Marlin

    You can follow the bug resolution on an issue made on official Marlin github:

    https://github.com/ErikZalm/Marlin/issues/26

    Currently, I'm able to compile deuligne support inside Marlin, but once uploaded on the arduino, I'm unable to connect to the serial port.

    If some of you have some ideas of where to look, I'd be glad to test them :)

    I'll keep you informed about any progress, tomorrow night is our hackerspace meeting, and I might find some help there too.

    Have a nice day,

    Alex

    Hi Tristan,

    Now that I use the newest Marlin, I'll try to adapt on it the Deuligne lib from last deccember.

    Hopefully, I could spend some time trying to use current ultipanel lib, but reminders from last november tell me I won't be able to debug the compilation error.

    I'll give more details on this thread once I open arduino :)

    Have a nice day, and sorry for the delay,

    Alex

    What are your alterations?

    Hi all,

    I'm trying to optimize my alteration files, and I'd like to know how you've tuned it on your side.

    This is the alteration files I use with skeinforge 48 and Marlin_v1 firmware, they were found on Ultimaker wiki :

    LCD with Snootlab Deuligne

    Yoopi :) First standalone print working, just with lcd+sdcard :)

    https://github.com/alx/Marlin/tree/deuligne

    How-to:

    - follow previous wiring instructions

    - with arduino software, load Marlin driver from Deuligne branch on your ultimaker pcb

    - in the main menu, go left to "Prepare", then execute preparation commands (homing, preheat, ...) by clicking on the joystick

    - while the preheat is finishing, you can go up to "Manual" in the main menu. Then press once the joystick to control Z axe, and lower a bit the bed. Click twice on joystick to go back to main menu

    - when the head begin to leak material (preheat is finished), you can right go to "Files", select a gcode file on your sd-card with up/down, and click on the joystick to launch the print.

    There're still a lot to code, but at least the proof of concept is validated :)

    Todo:

    - change the menu workflow to be more consistent with how you might use these menu to prepare and launch a print

    - auto-refresh of some screens (temperature control, printing progress)

    - add a potentiometer to have a control more precise at certain points. at the moment, some variable are hard-coded (axes control), and some variable will be useful to be changed during printing (feedrate, extrusion rate, temperature)

    - create and print a support to fix the electronic parts on the ultimaker :)

    Have a nice weekend!

    LCD with Snootlab Deuligne

    Hi all,

    Just a message to tell you that I've begin adding a lcd to Tetalab Ultimaker, using Deuligne shield from Snootlab, a open-hardware vendor we have in Toulouse, France.

    - Deuligne shield - 24€ -

    http://shop.snootlab.com/lang-en/snootl ... ligne.html

    - SD-card shield - 18.50€ -

    http://shop.snootlab.com/lang-en/snootl ... moire.html

    - EXP1 and EXP2 connectors - 4.10€ -

    http://shop.snootlab.com/lang-en/wires/ ... s-i2c.html

    Total cost: 46.60€ without shipping.

    Wiring is pretty basic, using documentation from:

    http://www.reprap.org/wiki/Ultimaker%27s_v1.5.4_PCB

    On EXP1, connect the Deuligne shield:

    - connect GND and 5V from EXP1 to GND and 5V on deuligne shield

    - connect 20 (SCL) to A5 on deuligne shield

    - connect 21 (SDA) to A4 on deuligne shield

    - for joystick: connect analog 0 on ultimaker pcb to A0 on deuligne shield

    On EXP2, connect the sd-card shield

    - connect GND and 5V from EXP1 to GND and 5V on deuligne shield

    - connect 50 (MISO) to 12 on memory shield

    - connect 51 (MOSI) to 11 on memory shield

    - connect 52 (SS) to 10 on memory shield

    - connect 53 (SCK) to 13 on memory shield

    I've began to rewrite my own lib on Marlin firmware, because I couldn't understand the problems I had with the current UltraLcd lib (which looks really cool with all the menu already done). Deuligne uses its own lib with i2c, and current UltraLcd use a standard LiquidCrystal lib, it might be causing the problem.

    I've made a Deuligne branch on Marlin github, so I can continue to merge most changes on master tree:

    https://github.com/alx/Marlin/tree/deuligne

    Basic menus are working, I hope to soon be able to print files from sd-card. I'll probably find a way then to re-attach to UltraLcd lib, it's painful to see so many good stuff so near :)

    Have fun,

    Alex
