- | **All of the previous stuff was pretty easy. This is where things | + | **Here’s |
- | Nozzle assembly | + | On first power-up, the fan above the effector must start up. If it does not then you need to immediately power off. The nozzle should also remain cold. If it heats up, turn off. If everything is good so far then it’s time to connect. |
- | This is the heated nozzle that I spoke about earlier. During printing, this nozzle will be heated to about 200°C. Attached to the nozzle is a metal block with two holes through it. Through the small hole we will (later) be putting a temperature sensing component, and the larger hole will hold the heater. | + | Well, almost. |
- | Bowden Tube | + | First, you need to put the contents of the zip file (from RepRapPro) onto the (supplied) SD card. |
- | The bowden tube is the tube that will connect the nozzle and the extruder. This is, quite probably, the most hair raising, and tricky, part of this assembly. You need to widen either end of this tube. You must use a slow drill, and a drill bit of exactly 2.5mm. Any other drill bit will mess this up. So it must be the right drill bit, and be done with a slow and steady hand. You drill about 10-15mm into the tube. The idea being that when you screw the tube into the nozzle, the internal diameter of the tube would shrink. Since it’s been drilled, it will shrink to the proper size. Same idea with the other end when you screw the little brass piece onto it. | + | Now, my Fisher |
- | Thermistor | + | I had to go into my ethernet connections and delete the existing network connection that was there. My laptop uses wifi for internet. Next, I created a new ethernet connection, clicked the IPv4 tab and for IP I entered 192.168.2.10 (since my network is normally on 192.168.1.1) and for the subnet I entered 255.255.255.0. Gateway was left blank. |
- | The thermistor is used to sense the temperature as close to the nozzle as possible. Remember that hole in the metal block I mentioned? Well, we need to take some heatshrink, shrink it round the thermistor, and later we’ll put the thermistor into that hole in the block.** | + | This now puts my laptop' |

- | Thermistance | + | J'ai dû aller dans mes connexions Ethernet et y effacer la connexion réseau existante. Mon portable utilise le WiFi pour Internet. Ensuite, j'ai créé une nouvelle connexion Ethernet, cliqué sur l' |
- | La thermistance est utilisée pour détecter la température au plus près possible de la buse. Vous souvenez-vous de ce trou dans le bloc de métal dont j'ai parlé ? Eh bien ! Nous avons besoin d'un peu de gaine thermorétractable que nous réduisons autour de la thermistance et, par la suite, nous placerons la thermistance dans ce trou du bloc. | + | Maintenant |

- | This is where the thermistor goes into the small hole in the nozzle block, the nozzle gets pushed into the effector, the heater goes into the larger hole in the nozzle block, the supplied fan gets clipped, and screwed, onto the effector, and a cable tie or two to keep things neat. | + | In a terminal I enter: |
- | Wiring | + | ping 192.168.2.10 |
- | This is where things need to be double and triple checked. The wires from the heating element, the fan and the thermistor go to a small socket. The wires must be in the right sockets or there will be bad problems! | + | Getting a reply to that means the Duet board is up and running. Doing: |

- | **The bed will sit on springs and touch screws that are on side pieces. These side piece screws are all linked together to form a loop, and when a screw on the bed is/isn’t touching the side piece screws, the printer knows where the bed is. After installing those wires, it’s time to fit the power jack and connect up everything to the Duet board. | + | déplacera le chariot X de 10 mm vers le haut. |
- | The wiring diagram is an ominous sight, but be careful and you’ll be OK as most looms can only connect to one place. Worst case scenario here is that your X motor becomes Y and such like. | + | Après plusieurs autres commandes pour vérifier chaque axe, il est temps de revenir... en position de repos. |
- | The bed of the printer is a plastic disc with a sheet that your hot filament will (hopefully!) adhere to. | + | De retour sur la page précédente, |
- | As mentioned before, the bed sits on springs and has a screw in either corner to bring it into contact with the side pieces I also mentioned earlier. | + | Et maintenant, la partie intimidante. |
- | There is a spigot to let you put the roll of filament onto the printer. I did attach this, but rarely have the spool on here. I usually leave the spool on the desk beside the printer. There’s also a top plate which I didn’t fit as I like to have my filament coming from above and down into the extruder.** | + | **Hot End |
- | **Drive Belts | + | It’s time to switch on the heater and see if we can extrude melted filament. This can be done using the ‘Heater’ link at the top left. When it reaches the temperature on the dropdown menu (190, maybe 200+), we can try using the manual winder on the extruder to get some melted plastic. |
- | After fitting more, incredibly tiny, screws into the pulley wheels, they fit to the three base motors. | + | In my case it worked! |
- | So how do the motors move the carriages? Drive belts. The drive belt is fed up through the carriage, up over the idler (at the top), down over the motor, and back into the carriage where it is wedged into place. But with a twist. No, not a plot twist, a twist in the drive belt. | + | I did have to tinker with the screw to give the extruder more grip.** |

+ | C'est le moment de brancher le réchauffeur et de voir si nous pouvons extruder du filament fondu. Ceci peut être fait en utilisant le lien « Heater » (Réchauffeur), | ||

+ | **Printing | ||
+ | |||
+ | To actually print something, you load a .g file from the SD card. To do this, click the ‘G-code File’ link on the left of the screen, and this lists all .g files that are on the card. Click the .g file and you’ll be asked if you really want to print this. Click OK and wait. | ||
+ | |||
+ | The RepRapPro zip file (from earlier) usually has a little MakerBot file on there to get you started.** | ||

+ | Pour vraiment imprimer quelque chose, vous chargez un fichier .g depuis la carte SD. Pour cela, cliquez sur le lien « G-code File » (fichier G-code) à gauche de l' | ||

+ | |||
+ | **Conclusion | ||
+ | |||
+ | From several weeks of printing | ||
+ | |||
+ | The printer is quick at whooshing back and forth to print plastic, but expect some prints (even small ones) to take quite a while. The little figure of the Kerbal Space Program character is only 12cm high and took just over one hour to print. Almost half of that time was me holding the base in place as I could see the nozzle was going to end up knocking it over. | ||
+ | |||
+ | Most will print without being held, but there’d be nothing worse than seeing a one hour print ruined by it tipping over. By rights, it shouldn’t happen, but we know that it inevitably will. | ||
+ | |||
+ | I have to say. This was money well spent. The instructions are excellent – with plenty of photos for every step of the procedure. Honestly, if you mess this up, you’ve no one to blame but yourself for not studying the photos, part lists, etc. | ||
+ | |||
+ | There are a ton of good things out there to print, but you need to convert them from STL format to the RepRapPro G format. How’s that done? I’m glad you asked.** | ||

+ | Je dois le dire. C'est de l' | ||
+ | |||
+ | Il y a une tonne d' | ||
+ | |||
+ | **Converting | ||
+ | |||
+ | Most models out there are in STL format which is no good for the RepRapPro Fisher. Thankfully we can use Slic3r (http:// | ||
+ | |||
+ | Next, following the instructions at: https:// | ||
+ | documentation/ | ||
+ | |||
+ | Now, grab a model from Thingiverse.com. That’s my favourite place for models. Save the file somewhere you can remember. | ||
+ | |||
+ | Load up Slic3r and at the top left, click ‘Add…’ and point it to the STL file** | ||
+ | |||
+ | Conversion | ||
+ | |||
+ | La plupart des modèles disponibles sont au format STL qui ne convient pas à la Fisher RepRapPro. Heureusement, | ||
+ | |||
+ | Ensuite, suivez les instructions sur : https:// | ||
+ | |||
+ | Maintenant, choisissez un modèle sur Thingiverse.com. C'est mon endroit favori pour les modèles. Enregistrez le fichier quelque part où vous le retrouverez. | ||
+ | |||
+ | Chargez Slic3r et, en haut à gauche, cliquez sur « Add... » (ajouter) et pointez sur le fichier STL. | ||
+ | |||
+ | **Slic3r will show you a 3D model of what we’re going to print. As long as the Fisher settings have been imported, we don’t need to touch the tabs at the top. See how it says ‘Fisher’ beside ‘Printer’ at the top right? That’s good. | ||
+ | |||
+ | Normally the model is shown in yellow. Click it, it’ll turn green, and display the info shown at the bottom right of the screen. Size is in millimeters, | ||
+ | |||
+ | The last thing to do is click the ‘Export G-code’ button and save the .g file somewhere on the SD card. | ||
+ | |||
+ | Pop the SD card into the printer, power it up, network into it, and get printing!** | ||
+ | |||
+ | Slic3r vous présentera une vue 3D de ce que vous allez imprimer. Pour autant que les paramètres de la Fisher aient été importés, nous n' | ||
