The short profile is covered by the housing in the preassembled device.
c) Setup and Transport When setting up the 3D printer, observe that the mains unit and the mains cable must be easy to reach so that the device can be switched off quickly and easily or be disconnected from the voltage supply in case of malfunction. Ensure proper ventilation when setting up the device. Do not put the device down on soft support such as a carpet or bed, etc. the air circulation also must not be impaired by other objects.
e) Adjustment of the Motor Driver Before first use of the printer, the 4 motor drivers must be reconciled. This is done generally at first by comparing the potentiometer on your controller to the respective screen. Finally, the fine settings are made with a digital multimeter. This should be able to measure 300 mV and 500 mV as precisely as possible.

15. Calibration a) General Notes on Calibration Attention! Never touch the hot extruder or the hot heat bed (preassembled device only)! There is a danger of burns! When heating, there may be slight development of smoke or steam. This is normal. Please ensure the corresponding ventilation. While calibration is underway, no filament must be inserted in the extruder. If there already is some filament in the extruder, it must be completely removed before calibration. For this, observe chapter "16.
b) Setting the Z-Stop Before starting calibration, set the end stop in the Z-direction. The hexagon screw should be about 1 to 2 mm in the thread. Counter the screw with the counter-nut.

The filament Push the ball bearing holder and insert the filament into the groove roll must move freely. of the ball bearing from below through the opening of the extruder The tip of the filament should be cut slightly diagonally. This makes motor holder. insertion easier.
b) Inserting the Filament via the Printer Menu Before inserting, removing or changing the filament, the corresponding extruder must be heated up so that the filament can be inserted into or removed from the extruder cleanly. Do not touch the hot extruder nozzle when inserting, removing or changing 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 be damaged otherwise.
Go to the item "Move X" and push the button of the operating knob Turn the operating knob (10) to the right until the desired value (10). "+110.0" is displayed. The extruder carriage is moved to the set Xposition. To return to the menu, push the operating knob (10).

The extruder infeed moves the filament by the set value.
Now the same value 0 as set before should be displayed here. The printer will switch back to the main menu automatically after a few seconds. Now the target temperature is displayed at 0 °C here as well. Below this, the dropping current temperature of the extruder is displayed. Insertion of the filament is then completed. As an alternative to the described method, you can insert the filament manually into the extruder as well after heating.
17. First Print of an Example Object from the SD Card When heating, there may be slight development of smoke or steam. This is normal. Please ensure the corresponding ventilation. If you are using PLA filament for printing and using the maker construction kit, stick the enclosed adhesive film on the printing plate for better adhesion of the printed object. Use the enclosed glue stick for the preassembled device.
The display switches back automatically to the main menu. Then move the axes to their home positions. The extruder is heated up. Once the extruder has reached its operating temperature, printing When the fan starts to run, the current speed is displayed under the starts. The display shows the positions of the individual axes (7). The fan symbol in % (6). already-printed time is placed below this. When printing is completed, the printing plate moves all the way Printing is thus completed.
It is possible that filament chips collect over time at the filament feed knurl. They should be removed under all circumstances (if possible) at once, e.g. by blowing off. Check and clean the filament feed knurl regularly! Otherwise, it is possible that the chips will adhere to the knurl and that no filament can be conveyed anymore because of this (the knurl slips through then). The fan at the extruder runs by default from 4th layer for PLA and ABS, provided that the slicer settings have not been changed.
18. 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.
19. 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 click on "Printer Settings" at the upper right in the window. (1) Select the printer "RF500_3D" in the menu above. (2) Set the port and check the baud rate. If you have selected the right printer in (1), the baudrate (2) is already correctly pre-set to "115200". The port number (2) is system-dependent. Usually, the setting "Auto" should work with the current version of the software (as of 1.6.2).
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" (1) 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. In the preassembled device, the basic settings have 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". Alternatively, you can also simply pull the file into the software. 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) *.
Short description of the most important buttons in the "Object Placement" tab: (1) Saving the object (2) Adding objects (as described above); several objects can be addend (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) Mirroring the object (6) Deleting the object from the printing plate (7) Scaling the object Use the scaling function to compensate the size retention of the printed object here as well.
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: RF500_PLA175_200_04 = RF500_1.75 mm PLA_layer thickness 200 µm (= 0.2 mm)_nozzle diameter 0.
The preassembled printing file appears in the graphics window after calculation. To the right of this, you will see a small overview for printing. This layer view serves to check for errors before printing. At 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: • Save the printing file on an SD card to print out stand-alone. For this, click "Save to file" (1). This saves the file as *.gcode and must be set at the same time when you save the file from the G-code editor (disc icon). The precise content of the G-code will be saved into the file here.
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 printing plate support and extruder can be carefully fine-adjusted manually with the 4 knurled screws at the bottom of the pressure plate. Turn all 4 knurls alternatingly and observe the printed line.
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 2 3 4 5 (1) Layer height (resolution of the printed 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 the outer wall layers (4) Activate for hollow bodies (e.g. vases) (5) Filled layer number top/bottom 1 2 (1) Object filling (0-100%) We recommend object filling of 10% to 40%.
1 2 (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.
You can set or adjust all speeds here. Chance the values only in small steps. Set the number of extruders here.
The extrusion width for all the different print versions can be set here. The extrusion width is the width of the output plastic thread. E.g., this may be increased at the first layer, so that the bottom of the printed object becomes denser.
Filament Settings 1 2 (1) Filament diameter and filament diameter tolerances according to the manufacturer's specifications 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 setting for the extruder and heating bed (in the preassembled device or when using the optionally available heating plate kit) separated by first and all other layers.
Printer Settings 1 2 (1) Geometric data of the printing plate (2) Number of the extruders 1 2 (1) The starting code contains the first commands that the 3D printer performs. (2) The end code will be performed at the end of the print and could contain, e.g. the run into a removal position for the printed object. Detailed information on the G-Codes can be found, e.g., in http://reprap.org/wiki/G-code.
1 2 (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.
i) Setting up Another Slic3r Version This chapter describes how to set up another version of the slicer "Slic3r", e.g. if you want to use an older version as well or if a new version has been published since. • First download your desired version of Slic3r. You can find the corresponding download under the following address. http://slic3r.org/download Then click the button "Windows". If you want to download an older version, click the folder "old/" in your web browser. Download the desired file.
• In the menu "Slicer", choose the desired Slicer that you want to integrate. In our example, this would be the standard selection "Slic3r". • In the field "Name", enter the desired name and confirm by clicking "Add Slicer". 6 1 3 2 4 5 • Select the newly added Slic3r by clicking it (1). • Right-click "Browse" (2). • Navigate to the new Slic3r program directory in the window that opens and select the starting file, in our example "slic3r.exe", by doubleclicking (3).
• In the tab "Slicer", select the newly added slicer in the drop down menu to slice an object. The settings "Print Setting", "Printer Settings" and "Extruder 1" are the same for both versions of the Slic3r. Of course, the configuration menu "Manager" also permits integrating another Slicer. The configuration here is similar, but is individually customised to each slicer, of course.
20. Firmware Update The firmware of the main PCB 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. New versions of the firmware are contained in the download package "BUNDEL_Vx_x_x_RENKFORCE_RF500". Update process The printer must be connected to the USB interface of the computer and must not be connected to any other software (for Repetier-Host, e.g.
1 3 2 • In the menu "Tools" (1), select option "Processor" (2) and set the type "ATmega2560 (Mega 2560)" (3). 1 2 3 • In the menu "Tools" (1), select the option "Port" (2) and set the correct port (3). The port number is system-dependent. You can find it in the device manager of the control panel, under connections (COM and LPT).
1 2 • In the menu "File", choose the option "Open..." and select the file "Marlin.ino" from the download package. The file "Marlin.ino" can be found under the following directory path, depending on whether your printer has a heating bed installed or not: \Download Bundel Vx-x-x.zip\Firmware-Source\Firmware RF500\Marlin-with-bed\Marlin-x.x.x\Marlin\Marlin.ino \Download Bundel Vx-x-x.zip\Firmware-Source\Firmware RF500\Marlin-without-bed\Marlin-x.x.x\Marlin\Marlin.ino • A new window opens.
21. Maintenance a) General Information Periodically verify the technical safety of the 3D printer, e.g. check for damage to the mains unit or of its mains line. If you have reason to believe that the device can no longer be operated safely, disconnect it immediately and make sure it is not operated unintentionally.
Cleaning the printing plate Be careful in the preassembled device or when using the optional heating plate kit: Danger of burns. Let the heating plate cool off before cleaning. Clean and degrease the heating plate thoroughly with a soft rag after each print. If you are printing directly on the glass panel, use a little acetone for cleaning. If you are using the adhesive film use a mild detergent with alcohol. e) Nozzle Change Caution: Danger of burns. Do not directly touch the hot nozzle and the extruder.
• Turn the extruder nozzle back into the heating block and tighten it carefully with a ring spanner, open-faced spanner or hexagon wrench (2). Never apply any strong forces for this. Secure the heating block again by twisting with an 11 mm open-faced spanner. • Then insert the filament again as described in "Inserting the Filament". • Switch off the extruder heating again and have the extruder cool off.
22. 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 connecting the voltage supply.
Printing stops during the process: • Check the settings of your computer. It must not switch to standby mode while printing (energy option settings) or simply shut down (installation of software or software updates during printing). • The printing table and its guide must not be installed tensed. In this case, loosen all screws, align the parts and tighten the screws again.
23. Handling • Never connect the mains plug to a mains socket immediately after the device has been taken from a cold to a warm environment. The resulting condensation may destroy the device. Allow the device to reach room temperature before connecting it. Wait until the condensation has evaporated. • Never pull the mains plug from the mains socket by the cable. Only pull it from the mains socket by the intended grip areas.
26. Annex a) Fine Adjustment of the Filament Infeed This chapter describes how to adjust the filament feed precisely, e.g. to compensate for the tolerance of the feed knurl. Preparation • If it has not been done yet, install the software Repetier-Host incl. the drivers and connect the printer to the computer (see chapter "19. Software "Repetier-Host"”). • If necessary, set the COM port and connect the printer.
• When the filament is marked, feed in precisely 50 mm. For this, move the mouse over the arrow at the lower left in the right control (see red arrow). When the mouse pointer is all the way at the bottom (see arrow tip of the red arrow) and the middle shows 50, click precisely once. • The filament motor now conveys precisely 50 mm filament and then stops again. • Now measure the remaining distance between the ball bearing holder and the mark just as you did when marking before. • In our example, 53.
Calculation and correction of the feed The formula for calculation of the actually conveyed volume is as follows: Total length in mm - residual amount in mm = actually conveyed volume in mm 100 mm - 53.37 mm = 46.63 mm The formula for calculating the new value "Steps per mm" is as follows: Conveyed volume in mm: Actually conveyed volume in mm * Current value Steps per mm = New value Steps per mm 50 mm : 46.63 mm * 127.
b) Setting up the Printer Settings This chapter is only targeted at users who do not have the custom version of the software installed. If you have installed the custom version (can be recognised by the image of the RF1000 3D-printer when the programme starts), you may skip this chapter. It only serves information purposes then. Start the programme Repetier-Host and click on "Printer Settings" at the upper right in the window.
