SHAREBOT Next Generation USER’S MANUAL
ATTENTION – EXTRUDER The fusion and extrusion system of the thermoplastic filament requires a heated end up to temperatures of 250 degrees and more. The contact, even for a very limited time, with the heated part causes burns. You must avoid to put your hands or other body parts in the printing area when printing and for minutes after the printing process is over. The current temperature of the extruder is indicated on the LCD screen.

Chapter 1 Preliminar Operations Anatomy of a Sharebot NG Your professional 3D printer Sharebot Next Generation is a tool of precision, ideated, developed and assembled in Italy by qualified staff. Before leaving the factory it was submitted to a quality control and to a quality test that guarantees its operation. It’s very imporant, before you can use the printer, knowing all the technical terms used in this handbook and identify all the specifical components that form a Sharebot NG. 5 3 4 3 2 3 1 1.

Opening the package Your Sharebot NG is equipped with a series of accessories that allow you to make it immediately operative; there is no software because it is open source and constantly updated. Software must be downloaded from the website of Sharebot to always have the latest version. With care and without damaging the packaging remove the various parts and elements that fix the printer inside the cardboard and then, by the internal metal frame, pull it out.
reel-carrier without any hindrances or preventing the entrainment of the wire by the extruder. For this reason, the printer may not be placed on a shelf that is at least 35 cm free space around the rear or side. Assembling the reel-carrier The two sides of the triangle shaped and coils are identical; start with the screw on a nut on one side of the threaded bar, leaving 15mm of thread and repeat on the other side.
Chapter 2 Process of 3D Printing Before you start printing with your Sharebot NG it is important to understand how you arrive at a finished object. This allows you not only to know what you need to do to give form and substance to your ideas, but it helps you to identify any constraints and limitations of the technology used by this printer.
Downloading from internet The net offers many ready-made 3D models, but also in this case there are differences between the models that you “see fine” and those who “print well”. A good indicator of the ability to print the pattern is of the form: the most popular 3D printing is STL (sites that intend to offer printable objects use this format). If there is no STL it is likely that the intended use is different and the result on a 3D printer is not guaranteed.
From a 3D model to a printing file The real “secret” of three-dimensional printing is the transformation of three-dimensional object into a sequence of two-dimensional slices that overlaping, reconstruct the object. Imagine a series of slices of bread: If the stack rebuilt the loaf from which they were cut. In the case of 3D printing every slice may consist of two-dimensional shapes not connected together as it is their sum to create the finished object.
the inside full, empty or partially empty, or the walls are made with one, two, three or more passes. Even the thickness of each layer is one of the parameters. The same object can be printed full, empty, with 100 or 200 slices and more or less robust and stiff despite having all versions a similar appearance.
Storing the files As we have seen, the process consists of the stages of modeling, creation of STL files, slicing into a GCode file and print. We recommend that you save the template file in the native format of the 3D modeling program, so as to keep any primitives that compose the object.
Chapter 3 LCD Panel Sharebot NG is a printer that supports both stand-alone operation and control from one computer (OS X, Windows or Linux). In both cases the LCD Panel provides functions both for consultation which edited.
The Control knob To the right of the display is a knob which rotates with small clicks and can be pressed as a button. With this knob you can interact with Sharebot NG: clockwise you decrease the selected value, turning it anti-clockwise will increase. During menu scrolling, rotation anticlockwise flows downward, that hourly rate upward.

material and higher values increase the extruded material from the value predicted by the G-Code. In all cases, it is a percentage. The latest rumor concerning the change of the filament while printing: the procedure arises from the need to replace the filament out with a new reel for use until after the previous coil, but this item can also be used to change the color of the filament or even the same type of filament by maintaining the ability to continue printing without defects in the object.
Chapter 4 Setting the printer Your Sharebot NG is a mechanical device built with care both in design and in the Assembly. To keep it in a State of optimal functioning is necessary to compensate for some normal processes of adjustment, for example, due to repeated thermal cycles of extruder motors and print heated dish. With each press, the entire machinery is subject to vibrations and movements that in the long run can loosen the four screws that hold the glass by the press.
Preparting the printing bed We remove the clothespins from the glass and extract it from the printer. Sprinkle over a thin layer of spray evenly up to cover the entire surface (light you will have a shiny effect). Now we await the complete lacquer drying and glass are placed on printing and secure it with pegs. Never spray inside the printer because it means severely damage the mechanical movements of the same and consequently invalidate the warranty.
Before you start any cycle of calibration, you should “parking” the second extruder on the left side of the printer and set it with the provided magnet. Automatic calibration cycles are designed to access all calibration screws with a single extruder. Manual Calibration This operation should be carried out with the tip of the nozzle clean, residue-free material. For cleaning of the nozzle there refer to Chapter 10.
Calibrating axes X and Y If printing your objects you find that the circles are not exactly round or that the joints, despite the necessary CAD drawn, tolerances don’t fit together properly, it is probably necessary to calibrate the X and Y axes on your printer.
Recognize the direction of the scrap, for example, if the flat part appears along the X axis (towards the front of the printer and printer), as shown in the figure above, it means that you have a game on the y-axis. The first intervention is checking the tension of the belts on the axis with the game, after that you can act via software to correct the same. In the start g-code of Slic3r or slicing software used enter the command M99 Y0 Y0 .2 .2, where stands for the game away to retrieve.
Putting in tension the extruder’s rubber bands Your Sharebot NG is equipped with a cushioned versus pulley sprocket wire drag. This solution allows to compensate for thickness variations that some filaments can have, allowing you to bring the press anyway. The correct tension of the compensating Springs allows optimum filament drive. Select the display “Prepare” menu the option “Change wire”. Wait until the machine ejector cycle terms and once finished, insert the wire.
Chapter 5 La nostra prima stampa 3D If you have followed the instructions in this manual, you’ve already developed your Sharebot NG by placing it on a table with door-coils, you connected the power supply, and you have turned on the printer, then the second extruder, scarrellato done the calibration plot and plan you have also uploaded the plot strand. Now you can proceed to your first print. If you have instead skipped some of the steps just listed, please go back and reread it before continuing.
heated floor, fans turned off). Once selected the profile displays the contents of the SD Card both in terms of file and folders. By turning the knob, you can scroll to the file you want. Pressing the knob you select for printing. Your Sharebot NG will start with the heating phase and by positioning the origin of the axes, then when it reaches the temperature you do in a central area of the press and will start with the first layer.
Modifying printing parameters One of the features of Sharebot NG is the ability to intervene on a number of parameters while printing is in progress. The “Adapt” menu becomes available instead of the “Prepare” (see Chapter 3): This allows you to adapt the selected profile PLA or ABS or normal to their compatible materials for behavior and characteristics (v. Materials table in Chapter 7), changing the nozzle plate temperature and the fan speed.
good seal, mechanical stress and just a little bit of shock on the extruder would jump away, ruining irreparably printing. Detach the model thus requires a certain expertise, a thin spatula or large blade cutter. Remember to place the maximum attention during the proceedings: we recommend wearing protective gloves to avoid cut with the blade or the glass plate.
peratures. The blocchettino of extruder solid brass remains for several minutes at temperatures sufficient to cause a burn. look at the temperature on the display and absolutely avoid any contact with it if the value indicated is higher than 50 degrees. If in doubt, do not detach the piece until the temperature has dropped to safe levels before you put your hands inside the print area.
Chapter 6 Creating G-Code files As well as modelling software, also for slicing software we have available a wide range of programs: from free and open source ones, until those paid professional. Free ones, we have selected Slic3r as reference slicing software, for his versatility that makes it usable by both beginners and professional users. Slic3r By Alessandro Ranellucci, is an open source program slicing; is scaribile for free at www.sharebot.it/download. We recommend that you download the version 1.1.
Just in case you have a dual-extruder and NG please make a double press extruder, load the profile “SharebotDualstrusion”. Otherwise unnecessarily heating energy sprechereste the second extruder. In the configuration file we included parameters related to all three tabs to allow you to have a starting point for reliable and experienced. If you want to create different profiles, you can adjust the individual parameters and save configurations with a new name.
Layer heigh: inside the tab “print settings” in the menu “layers and perimeters” you will find the entry “layer height”; This is the height of single layer and determines the printing resolution (for z-curves) and, consequently, the printing time. The preset value is 0, 2 mm and is a good compromise between speed and quality, but you can go up to 0.05 mm or growing up to 0.35 mm. Filling: next menu “infill” the voice “fill density” expresses the percentage of filling the template.
the complexity of the model and parameters set, it may take up to several minutes. The slicing, copy the g-code on the SD Card and we are ready for printing.
Chapter 7 Materials and printing plate One of the most critical elements in current 3D printers is the superficial treatment of the printing plate. When you extrude the filament, the first layer is crushed by the brass tip on the surface of the plate; If the contact surface is able to create a good bond with the molten plastic can continue printing with solid bases.
How PLA entails This material, created by processing the pulp plant waste rich in cellulose, comes from many preferred over to ABS, although most subject to high temperatures (over 60° tends to become slack). Printing between 195 and 230 degrees, depending on the additives that have been added to color it and modify its physical and mechanical properties. In relation to ABS is more environmentally friendly and does not emit almost no smell when printing.
Heated printing plate This is an option that allows you to improve the tightness of pieces on the printing plate thanks to flat heating to temperatures at which the ABS still has a certain plasticity and hasn’t undergone a deformation due to cool at room temperature. If you intend to print important parts in ABS this option is not only advisable but imperative.
Chapter 8 Consideration about models orientations The possibilities offered by your Sharebot NG are very broad, but like all technological tools, this must be understood and used by applying various measures over time more and more sophisticated. If on the one hand, as 3D printer technology, promises to create any shape but are frequent cases where a print ends with a big disappointment.
Just one object? There are cases when printing in one piece is inevitable, but there are as many cases where you can cut into several parts the object to print more easily. An example that you often see on the internet is that the Eiffel Tower: for his height would print a whole small object and with details too tiny to be created from most printers FDM.
Depending on the parameters and the shape of the model, and then create support structures read, so having a filament support. At the end of printing, with some patience, you remove these structures and the piece remains clean and with the shapes you want. Here is an example of an object that requires the supports accompanied by the G-Code generated with these supports The supports are vertical structures under the cheekbones and inside of the orbits.
Each type of object has its own range of optimum thickness for printing and only with a bit of experience you can intervene on this knowing what parameter are you going to actually meeting. Our tip is to choose a small enough, but with an articulated form, upon which to pursue a systematic experimentation, thanks to which you will be able to see the effect of each variation.
Chapter 9 Double extruders Printing with two extruders poses no particular difficulty if the calibrations of extruders physical and software were made correctly. Here are all the steps to get the perfect setup. We are assuming that your print plan is aligned properly with a single extruder, extruder detached from left to right and positioned on the left-hand side, in contact with the magnet of parking.
Offsets Two extruders printing toggles either to press extruder based on G-Code T0 (0 tool) and T1. When the firmware meets T0, using the main extruder (the right one), and when she meets T1 passes control to the left of the extruder motor. Basically, apart from steering gear of the motor either extruder, firmware continues to move the two print heads with the only trick to add an OFFSET to the coordinates of the G-Code to overlay exactly the point of the original coordinates T1 extruder.
Refining axes X and Y If there is staggering on a single axis, you must act on its value (M218 T1 X-nn, n Y0 that were found at the beginning of the G-code SM_Test_Bicolor_NG.Gcode), remembering that if you increase the negative value, you move the extruder more right (x) or more inside (y). Well stop printing the first layer until you have obtained a perfect centring eye.
change the position based on which in turn will be printed, so as not to find the clamp on the nozzle.
Chapter 10 Ordinary Manutention Cleaning the printer Sharebot NG does not require any special maintenance, but, like all machinery, efficiency increases if kept clean. Printing bed The first layer of the object we print is essential to the success of the press: for this reason the printing floor must be perfectly smooth, with a uniform layer of lacquer applied.
tighten the straps on the y-axis, we can adjust the screws placed on the top of the shoulders: side for clockwise will increase the tension and vice versa; to tension the belt of y-axis movement we need to adjust the two screws on the right side of the unit fastening the engine y: first must be loosened in order to then move down the engine by increasing belt tension; got the perfect tension tighten the two screws firmly.
