When heating, there may be slight development of smoke or steam. This is normal. Please ensure the corresponding ventilation. No filament may be entered in the two extruders during calibration, since the measured values would otherwise be falsified. If there already is some filament in the extruders, it must be completely removed from the two extruders before calibration.
b) Setting the Distance between the Nozzle and the Heating Plate Only the left extruder (viewed from the front) (Extruder 0) is used for calibration. The distance between the nozzle and the heating plate must be set to 0.3 mm. Important! Determine the position with the smallest distance between the nozzle and the heating plate in the cold condition.
Heating up the setting temperature Switch on the printer again and move the heat bed down a few cen- Use the direction buttons (1) to navigate to menu item "Extruder". timetres with the arrow "down" (3) once the main menu is displayed. Then push OK. Push OK. Push OK again to select "Temp. Bed". Use the direction buttons to set the temperature for the heat bed. Push OK. Since the distance is to be set at printing temperature, set PLA to "60 °C" and ABS to "120 °C". Select "Temp.
Push the direction button "left" 2 x to return to the main menu. Wait until the actual temperature of the left extruder and the heating plate reflects your setting. Let both continue to heat up for at least another 10 minutes until the heating plate temperature has stabilised and it is entirely heated through, and the extruder has completely expanded. Then push OK. Use the direction buttons to navigate to menu item "Position". Push OK. Use the direction buttons to navigate to menu item "Home Z".
Setting the left extruder (extruder 0) Take the strip of calibration tape (0.3 mm) (optional), or an 0.3 mm strip of a feeler gauge and push it carefully between the left extruder and the heating plate. Observe that the left figure has been recorded from the rear view. Therefore, extruder 0 is the right one here. Before you tighten the screw of the extruders again, the left extruder must be loosely supported on the calibration strip (0.
c) Executing the Head Bed Scan for PLA or ABS The text under the respective figure describes which buttons must be pushed or what must be set when this display is shown. Start of the heat bed scan Push OK (2) in the main menu. Use the direction buttons (1) to move to the menu item "Configuration". Push OK. Select "Z Calibration" with the direction buttons. Push OK.
Then the heat bed scan starts automatically. Align the right extruder and determine the current distance between the nozzle and heating plate at printing temperature. The printer moves to the home position with its Z-axis. The printing table is lowered a little. Directly after this, it automatically heats up the extruders to printing temperature. The temperature depends on which scan you performed (PLA = 230 °C, ABS = 260 °C).
d) Executing the Quick Head Bed Scan The text under the respective figure describes which buttons must be pushed or what must be set when this display is shown. Heating up the heat bed and the extruders Push OK (2) in the main menu. Select "Extruder" with the direction buttons (1). Push OK. Push OK to select "Temp. Bed". Set "100 °C" with the direction buttons. Push OK. Select "Temp. 0" with the direction buttons. Push OK. Set "120 °C" with the direction buttons. Push OK.
Select "Temp. 1" with the direction buttons. Push OK. Set "120 °C" with the direction buttons. Push OK. Push the direction button "left" 2 x to return to the main menu. Wait until the actual temperature of the extruders in the display is 120 °C and the actual temperature of the heating plate is 100 °C. Then let them heat up for at least another 10 minutes until the heating plate temperature has stabilised and it is entirely heated through and the extruder has completely expanded. Then push OK.
Push OK to select "Scan". Push the direction button "left" 3 x to return to the main menu. The status display of the main menu shows "Heat Bed Scan". The geometry of the heating plate is now measured automatically. This process will take a while. Aligning the right extruder After the measurement has been performed, the heating plate and the extruder carriage return to their home positions and then immediately move to the middle of the heating plate.
15. Inserting, Removing and Changing the Filament a) Inserting the Filament - Mechanical Part Push the filament rolls on the shaft of the filament holder. The filament Push the ball bearing holder on the outside and insert the filament rolls must move freely. through the ball bearing holder. Insert the filament past the feed motor into the extruder to the stop.
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 eextruder temperature to be reached at filament change and let the extruder heat for approx. another minute, since the extruder may break otherwise.
Push OK. Move to "Active Extruder" with the direction buttons. Push OK. Then the 2nd extruder is chosen as the active one (ex- Use the direction buttons to move to the menu item "Temp. 1". truder 1). Push OK. Use the direction buttons to set "200 - 230 °C" (e.g. for PLA). Push OK. Push the direction button "left" 2 x to return to the main menu. Wait until the extruder is completely heated.
The filament is now inserted. Push the direction button "left" 2 x to return to the main menu. Important! For the 2nd extruder, always choose extruder 1 as the active one. Then you can also perform insertion with the function "Load Filament". c) Removing and Changing the Filament Hold the filament when it moves out of the extruder. Otherwise, it may jump out and cause injury. The upper layers of the respective filament roll may jump open as well, which may cause the filament to tangle.
16. 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 printing with PLA filament, cover the heating plate with cleaning tape or a slightly structured crepe tape. You can purchase a special adhesive tape that has been developed for precisely this purpose. Alternatively, you can also use hair spray or a special glue stick.
The heating plate is heated up first. Then the axes move to the home position and the extruder is heated. Once the extruder has reached its operating temperature, printing starts. The progress of heating of the heating plate and extruder can be tracked based on the temperature displays in the upper display line. The printing progress can be tracked in the lower status display.
17. 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.
18. 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. • Select the printer "RF2000_3D" in the menu above (1). • Set the port and check the baud rate. If you have selected the right printer in (1), the baudrate (3) 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 finished 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.
Placing the object to be printed for 2-coloured print Two 3D-object files are usually used for printing a two-coloured object. The SD-card holds, e.g., a 2-coloured cube "Cube_1.stl" and "Cube_2. stl". One part is for the 1st extruder, the other part for the 2nd extruder. Insert the first file first and then the second file in the software as described above. Now centre the two print objects.
f) Preparation for Print To be able to print the object, it first needs to be sliced into individual printing layers or disassembled. 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_Extruder Example: RF2000_PLA300_200_04_S = RF2000_3 mm PLA_Layer thickness 200 µm (= 0.2 mm)_Nozzle diameter 0.
The finished 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. If you click "G-code Editor" at the upper right, the G-code editor will open and the G-code (the layer description) will be displayed.
Preparation of the object to be printed for 2-coloured print Now select the slicer settings that end with "D" for dual (e.g. "RF2000_PLA300_200_04_D"). If a message "At least one object is outside of the printed area..." appears when starting slicing, click "No" in any case. This cube is also very suitable for setting the extruder offset for X and Y. You can find the functions "Extruder Offset X" and "Extruder Offset Y" in the menu, under "Configuration" - "General".
g) Print 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 heating plate and the extruders can be fine-adjusted manually with the buttons for heating plate movement (3).
To ensure stable operation, print from SD card for longer printouts. Otherwise, it is possible that printing is interrupted because the printer is restarted via the USB interface. This can be caused by restarting the PC, re-initialising the USB controller or by a virus scanner. In the download area of the printer's product page on our website www.conrad.com, you can find a printing file "Roll holder" for download. You can install this on the filament holder to support the filament rolls.
Print Settings 1 2 3 4 5 (1) Layer height (accuracy/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. Here, the extruders can be assigned. For example, it is not possible to use one of the two extruders for "Infill" only.
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 settings for extruder and heating bed separated by first and all other layers.
Printer Settings 1 2 (1) Geometric data of the heating plate (2) Number of the extruders 1 2 (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 command then could be the following: M3006 S-100 (-100 are 100 µm or 0.1 mm in this case) If the value is prefixed with a - , the distance between the nozzle and heat bed reduces. A + will increase it.
Find a G-code below that controls the LED lighting. It can be integrated, e.g., into the start code or the end code. You can also use only parts of this. The comment (after the ;) says what the code does. The RGB control must be set to "Manual" in the "Quick Settings" menu for this.
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 Setting" and "Filament Settings" 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.
19. Expanded Calibration a) Determining the Highest Position of the Heating Plate As soon as the head bed scan has been performed once, the repetier host software can be used to read the matrix of the heating plate scan. The values of the matrix can be used to determine the position on the heating plate that has the shortest distance from the nozzle. This can generally be used for all other scans while nothing changes at the heat bed.
• Click the tab "Manual Control" on top. • In the field "G-Code", enter "M3013" (without the quotation marks) and click the button "Send". The command "M3013" outputs the values in steps. If you use the command "M3013 P1" instead, the values are output in mm. • The log field now shows the values of the matrix. • The first series of numbers (;7;0;20;40;...
Move to the offset position • First move all axes to their home position. For this, click the unlabelled house icon. If the figures in the fields X, Y and Z are red, no home position has been moved to yet. The software accordingly does not know where the printer axes are currently located. Once the home positions are reached, the colour turns black. • Now move the X-axis to the position previously read.
• Now move the Y-axis to the position previously read. • For this, enter the command "G1 Y90" (without quotation marks) in the field "G-Code" and click "Send". Replace 90 by your Y-value. The printer moves the Y-axis to the position. In our example, this is the Y-position 90. When the position is reached, the field Y will show the current position. In our example, this is 90.00.
b) 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. In our example, the left filament feed is calibrated. 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 "18. 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.
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 - 48 mm = 52 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 : 52 mm * 280.000 = 269.231 • After you have calculated the value, open the EEPROM configuration.
c) Fine Adjustment of Both Extruders In order to produce a perfect 2-coloured print, you may need to adjust the distances between the two extruders. This is also called the extruder offset. If the offset setting does not match the mechanical situation, the layers printed by extruder 0 and extruder 1 will not match 100% either. The firmware has 2 setting options for this. You can find the setting values in the menu item "Configuration" - "General".
Setting the determined values To set the value, first open the item "Configuration" in the menu and then the item "General". Navigate to "Extruder Offset X" and press OK (2). Set the determined value for the offset X with the two buttons "up" and "down" (1). Confirm with "OK" button (2). Navigate to the item "Extruder Offset Y" and press OK (2) again. Set the determined value for the offset Y with the two buttons "up" and "down" (1). Confirm the selection again with the OK button (2).
d) Correction of the Heating Plate Temperature The firmware makes it possible to adjust the temperature of the heating plate. For this, the actual temperature on the surface must be measured at different temperature settings. The measured values then must be entered in the firmware. This way, the printer can adjust the temperature automatically. Before starting, check if a new firmware version is available. If this is the case, download it, unpack the ZIP archive and install the firmware on your printer.
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. Download firmware For firmware updates, see https://github.com/RF1000/Repetier-Firmware. The latest firmware updates for the RF1000 and the RF2000 are provided there.
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 "Repetier.ino" from the downloaded firmware folder. The file "Repetier.ino" can be found via the following file path: „Repetier-Firmware-master\RF2000\Repetier“ • A new window opens. • In the new window, click the button with the arrow to the right in order to transfer the new firmware to the 3D-printer. Once the update has started, the USB connection to the printer must not be interrupted. This may cause irreparable damage.
21. 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. 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.
Method 3: If the procedure described above has not led to success, heat up the extruder to the printing temperature (PLA = 230 °C, ABS = 270 °C). Have the printer extrude some filament when the temperature is reached. Then let the extruder cool off. For PLA to approx. 90-110 °C and for ABS to approx. 110-130 °C. The proper temperature depends greatly on the filament used. You may need to repeat this process several times with different temperatures.
d) Checking the Belt Tension • Check the tension of the drive belts now and then. • If required, retention them by setting the belt tensioner with the setting screws so that the toothed belts can still be twisted by 180° easily with two fingers. The toothed belts must not be tensioned too strongly. If a belt tensioner bends, the belt tension must be reduced under all circumstances.
30 mm Now tip the printer to the right side near the edge of the table and at- Measure the distance between the two toothed belt halves as illustach the weight to the part of the toothed belt for the Y-direction that is trated. Set a distance of 30 mm with the belt tensioner (measured at now at the bottom using the cord. the outside of the toothed belt). For the extruder carriage to stay at the top as illustrated, simply bind the toothed belt together with a cable tie (see circle in the right image).
e) Nozzle Change Attention: Danger of burns. Do not directly touch the hot nozzle and the extruder. • 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 chapter "15. c) Removing and Changing the Filament". • Screw off the extruder nozzle (1) from the extruder with the enclosed 10 mm hexagon wrench (2).
Views of the available nozzles The following figures are to enable you to check your installed nozzle in case of a bad print pattern or if not enough filament is extruded. For example, it is possible that the tip of the nozzle is set incorrectly or comes into contact with the heat bed due to a printing error, and is scraped or damaged by this. Nozzle 0.4 mm (standard) - two marking rings Nozzle 0.5 mm - no marking ring Nozzle 0.
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 switching on. The display and print space lighting remain dark: • Check the connection of the mains line. • Check the mains socket.
• The strain gauges (DMS) may have been installed tensed. Proceed as follows to check this (no filament must be inserted): Note the measured value of the strain gauges. This is the value "F" (6) in the main menu. It is indicated in "digit". Push the extruder carriage or the strain gauges and the extruder holder from above and below, from the left and right. After the value has changed when pushing, it must approximately return to the starting position.
The printed object does not adhere to the heating plate: • The temperature of the heating plate is set incorrectly. Experiment with the temperature settings in steps of 5 °C for a prefect print result. • When printing problematic objects, it is beneficial to let the heating plate heat up for approx. 15 minutes before printing. • Check whether the heating (red foam material) adheres cleanly to the ceramics printing plate. It must not come loose (even partially).
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.
