2. Explanation of Symbols The symbol with a lightning bolt in a triangle is used where there is a health hazard, e.g. from electric shock. The device contains no parts that require servicing by the user. Therefore, never open the device. The exclamation mark symbol indicates that the user must read these operating instructions before commissioning of the device, and observe them during operation. This symbol warns of hot surfaces the contact with which may cause injury.
• Never reach into the 3D printer in operation. The mechanically moved parts within the printer pose a high risk of injury! • The print head and the heating plate grow very hot in operation. Never touch these parts during or just after operation. Let them cool down sufficiently first (approx. 60 minutes). • The mains unit corresponds to the applicable CE provisions.

14. General Notes on 3D Printing The print quality of 3D printers depends on a great many factors. It is not always possible to achieve a satisfactory print result at the first attempt. Extruder temperature The best extruder temperature depends on the filament material and the printer layer thickness. The manufacturer information for the printing temperature can vary very strongly here. Perform the first test prints at a temperature in the middle range of the manufacturer’s information.
15. Software “Repetier Host” a) General Notes on Software It is unfortunately not possible to explain the complete function of the enclosed software in the scope of this instruction. For this, we refer to the integrated online help function and the information on www.repetier.com. The basic operation and the path to the first printout are, however, described below to that you can get a result quickly and easily.
c) Connection of the Connected Printer Start the programme Repetier-Host and select printer settings at the upper right in the window. (1) Set the port and baud rate as displayed. The port number is system-dependent. You can find it in the device manager of the control panel, under connections (COM and LPT). (2) Click “OK”.
Click “Connect” in the upper left of the main screen of the software. After a few seconds, the symbol appears in green and the label turns to “Disconnect”. The printer has successfully been connected to the software and only some manual settings can be tested.
d) Manual Operation via the Software Click the tab “Manual Control” on the main screen of the software. Before trying out manual printer control, the settings for the limit switches for the Z and Y axes must have been performed (see pages 31 and 54). In the finished device, this has already been performed at production but should be inspected again for reasons of safety. If this is not observed, there may be damage to the 3D printer (loss of warranty/guarantee).
e) Placement of a Printing Object in the Software Click the “+” symbol on the main screen of the software in the object placement tab. Select the desired file and click “OK”. The 3D object “drops” onto the printing plate in the main window. The following file types can be opened with this software: *.stl (STL-files) *.obj (OBJ-files) *.3ds (3D-Studio-files) In the folder «STL» on the enclosed SD card, you will find a few examples for the first printing attempts.
Short description of the most important buttons in the object placement tab: (1) Adding objects (as described above) (2) Deleting the objects from the printing plate (3) Copying objects for multiple printing (in another window, the number of copies can be chosen) (4) Centring the object on the printing plate (5) “Dropping” again (this button should be pushed again before the further steps to ensure that the object is supported cleanly on the printing plate) (6) In the fields below, the object can still be m
f) Preparation for Print To be able to print the object, it first needs to be sliced into individual printing layers. This process is referred to as “slicing”. Slicing of the placed printing object (1) Select suitable slicer settings for your print. The settings are always marked with the following routine: Printer_Filament material_Layer thickness_Nozzle diameter Example: RF1000_ABS300_100_05 = RF1000_3mm ABS_layer thickness 100 µm (= 0.1 mm)_nozzle diameter 0.
The finished printing file appears in the graphics window after calculation. To the right of it, the G-code (layer description) appears, and below a control with which the layer view can be influenced. This layer view serves to check for errors before printing. In the very left of the screen, there is a tool bar that serves view control. For more detailed descriptions of the functions, see the online help function of the software.
g) Printing The printing file produced in this manner can be printed now. There are two options for this: (1) Click “Save Job” to save the print file on an SD card and then print it out stand-alone. (2) You can also click “Start job” to send the file directly to the connected 3D printer via the USB interface of the computer and print it. Here, the log window (3) below the image shows current information on software, slicer and printer during printing.
The graphics window may be switched to display temperature curves. There, the temperatures and their course are graphically displayed in a chart. During the first centimetres of printing, the distance between the heating plate and extruder can be manually adjusted with the buttons for heating plate movement (3). It should be approx. 0.2 mm (corresponds to about twice the paper thickness of regular 80g/m² printer paper).
h) More Detailed Description of the Slicer Functions Below some settings of the slicer are explained that are only to be changed by experienced users. The use of wrong settings can result in damage to the 3D printer or defective printouts. Beginners should first work with the basic settings that are integrated in the custom version in any case. If you make any changes to the settings, these must be saved in the configuration settings by clicking the disc icon.
Print Settings (1) Layer height (accuracy/resolution of the print object) (2) Layer height of the first layer (influences the adjustment and adhesion on the printing plate; set the first layer a little thicker than the following layers) (3) Number of outer wall layers (4) Activate for hollow bodies (e.g.
(1) Loops are circles, that are drawn around the object when printing starts, stabilise the filament flow before the actual object is printed. Here, number, distance from the object, height and minimum length are specified. (2) Brim is a thin edge that is placed right around the object to increase the footprint and thus adhesion to the printing plate. Here, the width of the brim is specified.
Filament Settings (1) Filament diameter and filament diameter tolerances according to the manufacturer specification are set here. If no manufacturer’s specification is present, these values can also be measured with a calliper (measure 1 m of filament material in 10 different points and then set the average here). (2) Temperature settings for extruder and heating bed separated by first and all other layers.
Printer Settings (1) Geometric data of the heating plate 84
(1) The starting code contains the first commands that the 3D printer performs. Here, e.g. a Z-compensation can be started. The Z compensation is unnecessary if the distance between the extruder nozzle and heating plate is set manually with the buttons of the operating fields (as described before when starting a printing process). Procedure for determination of the correct command: Move the printer to the home position. Switch off the motors and return to the main menu display.
(1) Setting of the nozzle diameter (2) Settings for the filament withdrawal if the extruder moves to another position of the printed object during printing. If the filament was not withdrawn here, there would be drop or string formation that would negatively influence printing quality. 16. Software “Cura” a) General Notes on Software It is unfortunately not possible to explain the complete function of the “Cura” software in the scope of this instruction.
c) Setup of the Software • Connect the 3D printer to a free USB interface of the computer and switch it on. • If the printer has not been connected to the computer before, the operating system recognises new hardware and is looking for the corresponding driver. • Select manual driver selection and enter the directory.
(1) Select “Other” in the next window. (2) Confirm the selection with “Next” (1) Select “Custom...” in the next window.
(1) Enter the values shown in the figure in the field on the following screen. (2) Click “Finish” to complete the wizard. The software starts and there is already an object on the printing area.
(1) Select the serial port to which your printer is connected. The port number is system-dependent. You can find it in the device manager of the control panel, under connections (COM and LPT). (2) Set the baud rate as shown. (3) Click “OK” to save the changes. (1) Click “File”. (2) Select “Open Profile”. Select a filament configuration file for the filament used by you in the selection window and confirm your selection. You can find the configuration file “Settings.
d) Use of the Software in the Quickprint Mode (1) Click “Expert”. (2) Select “Switch to quick print...” The software interface is now simplified and only very few settings need to be made before printing. This surface is ideal for producing the first test prints and familiarising yourself with the software settings and the resulting changes. In Quickprint mode, start and end G-Codes or Z-calibration are not supported.
Starting print At PLA printing of small objects with a small footprint, it is recommended to apply the heating plate with cleaning tape or a slightly structured crepe tape before printing. This increases adhesion of the printed object on the base plate. (1) Click the symbol for “Print”. (2) In the next window, click “Print”. e) Use of the Software in Expert Mode (1) Click “Expert”. (2) Select “Switch to full settings...” The software interface now has a lot more setting options.
Find some information on the possible settings enclosed: (1) Thickness of the printing layers (2) Strength of the outer hull of the printing object (3) Thickness of the bottom and lid filling of the print object (4) Density of the filling (5) Printing speed (6) Extruder temperature (7) Heating bed temperature (8) Selection of different supporting structures when printing bridges, etc.
17. Filament Change Before filament change, the extruder must be heated so that the old filament can be cleanly replaced from the extruder. Do not touch the hot extruder nozzle when replacing the filament, danger of burns! Always wait for the extruder temperature to be reached at filament change and let the extruder heat for approx. another minute, since the extruder may break otherwise. (1) Switch on the extruder heating.
18. Firmware Update The firmware is updated frequently to optimise the properties of the 3D printer. The currently installed firmware version of your printer is briefly displayed in the upper display line after switching on the printer. For firmware updates, see https://github.com/RF1000/Repetier-Firmware. Here, the most recent firmware updates are provided. You can choose between two “branches”: “Master” is the final version of the firmware.
• In the menu “Tools”, select the option “Serial port” and set the correct port. The port number is system-dependent. You can find it in the device manager of the control panel, under connections (COM and LPT). • In the menu “File”, choose the option “Open...” and select the file “repetier.ino” from the downloaded firmware folder. The file “repetier.
• A new window opens. • Click “Upload” in the menu “File” here to transfer to the new firmware to the 3D printer. • After a successful firmware update, the 3D-printer will start again and briefly display the new firmware version in the first display line after the start. 19. Maintenance a) General Information Periodically verify the technical safety of the 3D printer, e.g. check for damage to the mains cable and the casing.
b) Cleaning Device The outside of the 3D printer should only be cleaned with a soft, dry cloth or brush. Never use any aggressive cleaning agents or chemical solutions on plastic parts, stickers or the display since these parts would be damaged otherwise. Nozzle cleaning Caution: Danger of burns. Do not touch the hot nozzle directly. Outside cleaning of the nozzle: Carefully wipe off the extruder nozzle after each print using tissue paper or similar. The nozzle still has to be hot for this.
Method for precise setting of the belt tension For this, you need a weight of 1 kg, such as a water bottle filled with water to reach the specified weight of 1 kg. You also need a cord for attachment. Fasten the heating plate with adhesive tape or similar first to keep it from falling out and being damaged if the printer tips. Place a soft support under the printer so that it is not scratched when tipping and so that it cannot damage the table top.
Now tip the printer to its rear near the edge of the table and Measure the distance between the two toothed belt halves as attach the weight to the part of the toothed belt for the Z-direc- shown in the figure. Set a distance of 41 mm with the belt tention that is now at the top using the cord. sioner. The weight must be suspended to be freely movable but may touch the mains unit housing. This is not a problem.
e) Nozzle Change Caution: Danger of burns. Do not touch the hot nozzle or the extruder directly. • To replace the extruder nozzle, the extruder must first be heated to a temperature suitable for the inserted filament material. • When the temperature is reached, remove the inserted filament material as described in “Filament Change”. • Screw off the extruder nozzle (1) from the extruder with a 10 mm hexagon wrench (2).
21. Troubleshooting With this 3D printer, you have purchased a product that is built to the state of the art and operationally safe. Nevertheless, problems or errors may occur. Therefore, we would like to describe how to eliminate possible errors here: Always observe the safety information! The 3D printer does not work after switching on. The display and print space lighting remain dark: • Check the connection of the mains line. • Check the mains socket.
The filament supply breaks off or there is not enough filament material supplied: • Check the filament unroller. It must turn easily. • Check whether the filament material has caught on the filament unroller. The filament hose at the filament roller may have caught. • Some filament types do not slide through the filament hose properly. If required, use the alternative filament holder that you can print from the SD card (file name “Filament_guide.gcode”).
