== Description ==
Cette page recensera toutes les recettes à base de mate que j'aurai testé.

== Objectif ==
* Avoir une procédure simple avec comme vérification que n'importe quel membre puisse reproduire la recette sans l'aide d'un des concepteurs
* le goût doit ressembler au Club Maté
* la boisson doit plaire aux membres
* pouvoir reconnaître le goût du maté
*
*

== Recettes ==
=== 1. HackPittsburgh's Open Mate Soda ===
* http://www.hackpittsburgh.org/brewing-open-mate-soda
=== 2. Matedor - Sirop au goût de Club Mate pour les machines Soda Stream ===
* https://github.com/Tobystereo/Matedor
==== v.1.0 ====
Ingrédients: 5dl eau, 500 gr sucre et 10 gr acide citrique.

Dans un premier temps j'ai chauffé 1 litre d'eau à ~80°C et ai utilisé 70 gr de maté. J'ai laissé infuser 30 minutes pour au final utiliser que la moitié du liquide.

Résultat: l'acide citrique était un peu trop présent.

==== v.1.1 ====
changelog:

J'ai laissé le maté infuser plus d'une journée. La seule différence était visuelle.

=== 3. Club Mate Copycat ===

'Prices per month - proposition by pld.

We should add 'cheaper' tiers with key, but also more expensive ones that add meaningless advantage so some can donate more discreetly if they want.

==== Propositon 6 ====
La cuisine va gentiment être disponible pour les membres. L'idée serait alors d'instaurer un supplément au cotisation permettant de financer les repas. Ce financement permettra ainsi à la personne de manger sans charge supplémentaire. Reste à voir le montant par mois et comment cela sera concrétisé dans la pratique ^^

Donations are activly encouraged.

== Usage ==
# '''Prepare a 3D model to print'''. You can [[#Find model online|find a model online]] with sites such as [http://thingiverse.com Thingiverse], or [[#Make your own|create your own]] in software such as Sketchup or OpenSCAD. You will need to save the model as a .STL file, however .DAE can also be used for direct exports from Sketchup.
# '''Import your model onto the print computer'''. It is easiest if you print using our dedicated print computer (Fixme-SPM) which is located next to the printer. You can import the model by dragging it into the [https://foo.fixme.ch/marcha/ drag and drop service], using a USB key, using IRC, or using a cloud hosting service such as [http://ge.tt/ Ge.tt] or [https://mega.co.nz/# Mega].
# '''Open Cura and open your model(s)'''. Open Cura from the sidebar, and click on the [https://fixme.ch/w/images/d/dd/Cura-load.png Load button]. Select one or more .STL or .DAE files that you would like to print. Please note that prints that reach near the limits of the print volume (21 x 21 x 20.5 cm) will fail.
# '''Configure your desired print parameters'''. The print parameters will depend on what you are printing and the quality that you're looking for. Here are some guidelines:
## '''Layer height''': the Ultimaker can print between 0.1mm and 0.25mm. 0.1mm should only be used for high precision, high detail prints; 0.15mm should be used for normal prints; 0.2-0.25mm should be used for fast prints where you don't mind the quality (e.g. holder, internal component, etc).
## '''Shell thickness''': this value should be a multiple of 0.4mm (the width of the nozzle). With 0.4mm you'll get 1 solid layer, with 0.8mm you'll get 2 solid layers, etc. 0.8mm is fine for most prints.
## '''Enable retraction''': this retracts the filament when the nozzle moves from one area to another whilst not printing. It is best to leave this enabled.
## '''Bottom/top thickness''': the bottom and top thickness of the solid layer. This value should be a multiple of the layer height - a value between 0.2mm and 1mm is best for most prints, with 1mm used for very delicate models.
## '''Fill density''': this is the density of the fill inside your model. Due to an excellent calibration of our Ultimaker, almost all prints will require less than 30% fill. 10% for just structural support, 24% for an average print (after 25% Cura slices your model differently), 30% for a solid print of an average sized object. For objects that require superior structural strength, up to 60% is recommended. 80% can be used for very small complex objects, and 100% is used on a case-by-case basis.
## '''Print speed''': this is the speed at which the Ultimaker will print. 100mm/s is recommended for detailed prints, 120mm/s for average prints, and up to 150mm/s for fast, lower quality prints.
## '''Printing temperature''': we have tested and 235°C works best. Leave it as is.
## '''Support type''': only use for prints with significant overhangs.
## '''Platform adhesion type''': not required for PLA prints.
## '''Diameter''': the diameter of the filament (currently 2.89mm). Do not touch this unless you are changing the filament and have remeasured it (sometimes the value does not match the specification).
## '''Flow''': I have no clue what this does. If it ain't broke, don't touch it.

==== Printing software ====
* https://print.fixme.ch web interface to replace Printrun/Cura (still need Slic3r to create the gcode)
** Currently not connected to the printer and the service is down
** run as unprivlilegied user please sudo su -c /home/francois/OctoPrint/run francois
** Used for the webcam: http://webcam.fixme.ch
* [http://slic3r.org/ Slic3r] and [http://reprap.org/wiki/Printrun Printrun]
** [https://github.com/daid/Cura Cura]
* To check, http://projectsilkworm.com/
* Check STL files for printability: http://cloud.netfabb.com/
* Buy material in switzerland: [[Resources#3D_Printer]]
* There's a dedicated machine to print: spm.fixme.ch

== Printing ==
=== Software Installation ===
* http://daid.github.com/Cura/
* it's the only software worth it
* Yes, you will need PyOpenGL for it to run. Displaying nice 3d images is not that trivial.

* Recommended: Use the dev version on github: https://github.com/daid/Cura.git (12.10 when I'm writing)
* Required packages: wxPython and PyOpenGL.
* You can use a python virtualenv.

=== First use ===
* On first Cura start, you don't need to upgrade to Marlin firmware because it's already done.
* You should run the checks, at least to check if USB connection between PC and the printer is working. For temperature check, the printer need to cool down (to ~30) before heating and check, it can take looong time.
* Now you can use Cura to print objects.

=== Printing ===
'''Maximum length/width: 180mm'''
* Load a .stl model.
* Change orientation, size, etc...
* Check settings on the left (and in the different tabs)
* Click on the Prepare print button.
* Software will slice the object into GCode. The more you choose a large scale object, the longer the execution time is.
* When it done, click on Print button to open the Printing dialog.
* Wait the software connect with the printer, Connection button will turn from clickable to readonly and Print button will turn from readonly to clickable.
* Set the temperature with the arrows (yeah it's not working by putting the number directly)
* Wait a bit so the hot end is distributively warmed
* Extrude before printing, so the wire is at the start of the hot end
* Make sure the wire is extruding correctly (the output wire is regular)
* Click the Print button.

==== Settings ====
* Walls: 0.4 (1 wall) is good
* Print speed: 80mm/s is clean (you may increase temperature for more speed)
* Infill:
** strong material, 80-100%
** Light print, 10-15%
* Temparatures: ~230-240°
* Support type:
** Exterior when there's a big overhang (we made a 10cm overhang without support, but generally it's >1cm)
** None in general
* Raft: needed when there are small pieces at the bottom (so they stick to the bed)
* Experiment !

=== Important points ===
* '''[https://webcam.fixme.ch/ KEEP YOUR EYES] ON THE PRINTER THROUGHOUT THE PRINTING PROCESS!!!''' And clean what could interfere with the printing.
* BE carefull with the end stops, [http://www.youtube.com/watch_popup?feature=player_embedded&v=IYXnxllWcyc if they don't work], turn OFF the printer immediatly and fix them (by bending the metal part a little bit for instance)

=== After printing ===
* If a pile of plastic has formed in the extruder, remove the wire complitely and cut it
* Put the leftover in the box, maybe one day we'll be able to [http://www.filabot.com/ recycle it!]

== Finance ==
* To buy new PLA filament and upgrade parts, there's a piggy bank next to the printer
* The cost in filament is indicated by Cura, just take a guess to add general maintenance cost of the printer
[[File:piggy.png|300px]]

== Files ==
You can find 3D models to print from [[#Find model online|this list of websites]]. There is also a folder full of previously printed STL's on the machine attached to the Ultimaker.
