11. First commissioning a) Overview of the first steps The following overview shows the first, important steps with the RF2000 v2. This is a brief summary of the subsequent chapters until your first print with the printer. • Completion of initial commissioning. Some important things are explained to you here that you should do in any case after transport and unpacking.
b) Installation of the filament holder Assembly of the filament holder 2 x filament holder part 1 x shaft for filament holder 4 x nut M4 (black) 4 x cylinder head screw M4x20 (black) The two filament holder parts are installed on one side of the printer each in the two upper rear holes (see arrows in the figure). If you have purchased the finished device, the 4 cylinder-head screws and nuts will be enclosed.
Fold the rear head cover up so that you can have access to the lower Attach the upper screw hand-tight with a nut M4. It currently only attachment screw of the right filament holder (from the rear view). serves to secure. Insert one cylinder-head screw each into the two mounting holes. Attach the lower holding screw of the filament holder and tighten it at once. It is easiest to install the nut with one finger and then tighten it with a hexagon socket wrench.
c) Inspection of the fan sheet and the actuation for the Z-limit switch The two extruders should be in the home position. This means that they both need to touch the extruder holder on top. The fan sheet height must be set so that the two upper screws of the two rear fans do not tough the X-plate (left figure). At the same time, the fan sheet must be above the two tips of the extruder nozzles (right figure). Of course, it should also be as straight as possible in reference to the extruder nozzles.
d) Setup and transport When setting up the 3D printer, observe that the mains switch or the mains line at the low power device combination socket 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. The emergency off switch must be easy to reach as well! Ensure proper ventilation when setting up the device. Do not put the device down on soft support such as a carpet or bed, etc.
12. Software and firmware installation a) Download and unpacking of the software/firmware package The software, firmware, tools and printing examples needed for the printer are available online as a download package. These are regularly updated. Therefore, check occasionally whether a new version may be available. The download package is at the same time the content of the SD card. This means that if a new version is available online here, you should update your SD card at the same time.
The software Repetier-Host performs the following tasks: • Placement of the 3D-object to be printed on the printing plate. • Slicing of the object to be printed into thin layers that the 3D printer can print out layer for layer. The result of this process is a G-code file. • Review of the G-code files for error and printability. • Sending the G-code files to the printer or saving on an SD card for standalone print. • Monitoring the 3D printer in operation.
13. Operation at the printer a) Description of the main display This is the first display in the main menu. The further displays that you can call in the main menu are described in chapter "13. d) The expanded main menu".
b) Function description of the operating buttons 3 1 4 2 5 6 (1) Direction buttons for navigation in the menu structure ("left" / "right" / "up" / "down") The left direction button switches the LED lighting to white light as well. Pushing the button again will switch back to the previous condition.
d) The expanded main menu The main menu contains the main display (see chapter "13. a) Description of the main menu") and 4 further views. You can reach them via the direction buttons "up" and "down" (1). The displays are switched through in sequence. For example, if you push the button "down" five times, the main display will be shown again. 1 x button "down" (1) pushed. This shows the current positions of the individual axes. 2 x button "down" (1) pushed.

14. Calibration a) Overview of calibration This provides a brief overview of the calibration of the RF2000 v2. • Determining the position with the smallest distance. Here, you can determine the highest position on the printing plate that has the shortest distance from the extruder nozzle. All settings are based on this position. Therefore, you should determine this position as precisely as possible. • Basic settings of the upper Z-limit switch. This setting usually is only required once.
Before you perform calibration, first check if new firmware is available and install this. Observe chapter "12. Software and firmware installation" and chapter "20. Firmware update with the ArduinoTM IDE". The update to the new version may cause data of the heat bed scan to be deleted. To check this, just read out the data with the command "M3013", as described in chapter "19. a) Determining the highest position of the printing plate". If this shows a matrix, it has not been deleted.
c) Setting the distance between the nozzle and the printing plate Only the left extruder (viewed from the front) (extruder 0) is used for calibration in the dual extruder. 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. The basic setting of the upper Z-limit switch (Z-min.; light barrier) also takes place in the cold condition.
Basic setting of the upper Z-limit switch (Z-min.; light barrier) min. 0,8 mm max. 1,0 mm For finished devices, this basic setting of the upper Z-limit switch has already been performed. If you have checked the distance at "Determination of the position with the smallest distance" and this is correct, you can skip this page and continue with "Heating up to the setting temperature". If something changes at the printing plate later, check the distance again and adjust it if necessary.
Heating up the setting temperature Move the printing plate down by a few centimetres with the arrow Use the direction buttons (1) to navigate to menu item "Extruder". button "down" (3). Then push OK. Push OK. Push OK again to select "Temp. Bed". Set the temperature for the printing plate with the direction buttons. Push OK. Since the distance is to be set at printing temperature, set PLA to "60 °C" and ABS to "120 °C". Use the direction buttons to select "Temp. 0". Push OK.
Push the direction button "left" 2 x to return to the main menu. Wait until the actual temperature of the left extruder and the printing plate reflects your setting. Let both continue to heat up for at least another 10 minutes until the printing 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 a 0.3 mm strip of a feeler gauge and carefully push it between Hold the left extruder at the top at the inlet and carefully release the the left extruder and the printing plate (see arrow in the figure). left screw of the extruder holder. Carefully lower the extruder to the strip of the feeler gauge. Before you tighten the extruder screw again, the left extruder must be applied loosely to the calibration strip (0.3 mm).
d) 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 Briefly push the button OK (2) in the main display. Use the direction buttons (1) to move to the menu item "Configuration". Push OK. Use the direction buttons to select "Z Calibration". Push OK.

e) 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 printing plate and the extruders Briefly push the button OK (2) in the main display. Use the direction buttons (1) to select "Extruder". Push OK. Push OK to select "Temp. Bed". Use the direction buttons to set "100 °C". Push OK. Use the direction buttons to select "Temp. 0". Push OK.
Use the direction buttons to select "Temp. 1". Push OK. Use the direction buttons to set "120 °C". 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 printing plate is 100 °C. Let then both continue to heat up for at least another 10 minutes until the printing plate temperature has stabilised and it is entirely heated through, and the extruder have completely expanded.
Push OK, to select "Scan" and start the heat bed scan this way. Push The status display of the main menu shows "Heat Bed Scan". The the direction button "left" 3 x to return to the main menu. geometry of the printing plate is now measured automatically. This process will take a while. Aligning the right extruder After the measurement has been performed, the printing plate and the extruder unit return to their home positions and then immediately move to the middle of the printing 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. The filament must be guided in a straight line from the top between the feed motor and the ball bearing into the bore at the extruder.
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 extruders 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.
Push OK. Use the direction buttons to navigate to "Active Extruder". Push OK. Then the 2nd extruder is chosen as the active one (ex- Use the direction buttons to select the 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 right 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. When printing with PLA filament and any problems occur with adhesion of the printed objects, glue masking tape or a slightly structured crepe tape to the printing plate. You can purchase a special adhesive tape that has been developed for precisely this purpose.
The printing 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 printing 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) 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 in the menu above (1). In our example, this is the "RF2000v2_3D_Dual" with dual extruder. Owners of the single version must select the single version "RF2000v2_3D_Single" accordingly. • Set the port and check the baud rate.
Click "Connect" in the upper left of the main screen of the software. After a few seconds, the symbol swill switch to a connected plug and the label turns to "Disconnect". The printer has successfully been connected to the software and only some manual settings can be tested.
b) 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).
c) 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 and displayed in a close view. The scroll wheel of the mouse can be used to zoom out of the view again so that you can see the entire virtual printing plate once more.
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 wel
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. You will find the files in the folder „\STL\Dual_Cube“. Insert the first file first and then the second file in the software as described above.
Then click the drop down menu in the yellow area behind "Cube_2" and switch the extruder from 1 to 2.
d) 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 the placed object to be printed for 1-coloured print 4 1 2 3 (1) Switch to the tab "Slicer" and select the slicer for your printer in the drop down menu "Slicer:". In our example, this would be the slicer "RF2000v2". It does not matter whether you use the RF2000 v2 with single or dual extruder.
Printer Settings (in the slicer settings also "Printer Settings") Filament material_nozzle diameter_extruder Example: GENERIC175_04_SINGLE = 1.75 mm PLA (all filament manufacturer)_nozzle diameter 0.4 mm_single extruder (for single-coloured print) If you want to print an object in 1-colour, select the setting with "SINGLE" here. For 2-coloured printing, select the setting with "DUAL" (see second to next page).
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. The control below can influence the layer view. Preparation of the object to be printed for 2-coloured print This section is only relevant for owners of the dual extruder version of the RF2000 v2. Now select a setting with the ending "DUAL" for slicing in the "Printer Settings" (e.g. "GENERIC175_04_DUAL").
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". This setting corrects the distances of the two extruders. X corrects the distance between the two extruders, i.e. when the printed object is offset to one side.
e) 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.
3 5 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).
If you have performed the heat bed scan for PLA (Scan PLA) or ABS (Scan ABS), the printer should already set the optimal distance between the nozzle and printing plate when printing. If you have only performed a quick head bed scan (Scan), you can adjust the distance with the item "Z Offset" in the menu "Configuration" - "Z Calibration". When the automatic Z-compensation is active, the display will show "Cmp" next to the Z-position (5).
f) 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.
First, select the settings to be changed in the slicer window (1). Then click the menu "Settings" (2) and open the item "Print Settings..." (3). 2 3 1 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.
1 2 (1) Object filling (0-100%) We recommend object filling of 10% to 40%. (2) Filling pattern of the object and the first and last layer 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. For 2-coloured printing objects, a wall will be drawn around the object that is used to wipe off the extruders.
1 (1) Selection and adjustment of the supporting material that is needed when printing complex objects such as bridges or hollow spaces (poss. required for printing object with overhangs > 45°). The first printing attempts should be without a supporting brim since the result here is usually better again. 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 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.
1 (1) The notes field may contain important information on the slicer setting. This may also contain information on the filaments with which this setting was tested or compiled. If there is a note here, it only applies to the this slicer setting, e.g. to "PLA175_200_04". Please also observe the note fields in the tabs "Filament Settings" and "Printer Settings". Click the menu "Settings" (1) in the slicer window and open the item "Filament Settings..." (2).
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.
Click the menu "Settings" (1) in the slicer window and open the item "Printer Settings..." (2).
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. (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.
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. The tabs "Extruder 1" and "Extruder 2" must be identical at least for the regular dual pressure.
g) 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.
• First click the slicer of your printer and write down or copy the path of the configuration directory. • In the menu "Slicer", now choose the desired Slicer that you want to integrate. In our example, this would be "Slic3r". • In the field "Name”, enter the desired name (e.g. "RF2000v2_1.2.7") and confirm by clicking "Add Slicer". When choosing the name, observe that the newly set-up slicer is also only for one printer. 7 5 1 2 3 4 6 • Select the newly added Slic3r by clicking it (1).
• In "Slicer:", select the original Slicer of your printer and click "Configuration". • Click "File" and then "Export Config Bundle...". Save the file on your PC. • Close the window again. • Now select the newly created slicer in "Slicer:" and click "Configuration" again. • When the new window for the slicer configuration opens, the configuration assistant is displayed first. Cancel it with "Cancel". • A message may be displayed to inform you of a new version. Close the message with "No".
• When the new Slicer is selected at the top in "Slicer:", you can use the same slicer settings at the bottom in the menus ("Print Setting"; "Printer Settings"; "Filament Settings") as in the original slicer of your printer. Please note! You may have to adapt the imported settings to the new slicer version. • In order to slice an object with the new version, select the settings "Print Setting", "Printer Settings" and "Filament Settings" for the new slicer.
19. Extended calibration a) Determining the Highest Position of the Printing 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 printing plate scan. The values of the matrix can be used to determine the position on the printing plate that has the shortest distance from the nozzle. This can generally be used for all other scans while nothing changes at the printing plate.
• 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 of the matrix 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 Y250" (without quotation marks) in the field "G-Code" and click"Send". Replace 250 by your Y-value. The printer moves the Y-axis to the position. In our example, this is the Y-position 250. When the position is reached, the field Y will show the current position. In our example, this is 250.00.
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 "12. Software and firmware Installation"). • If applicable, enter the COM port and connect the software to the printer (see chapter "18.
• 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 - 46 mm = 54 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 : 54 mm * 280.000 = 259.
c) Fine adjustment of the two extruders This chapter is only relevant for owners of the RF2000 v2 with dual extruder. 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.
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 printing plate temperature The firmware makes it possible to adjust the temperature of the printing 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 with the ArduinoTM IDE 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. The update with the ArduinoTM IDE enables you to change the firmware before installation and to adjust it on demand.
• Start the ArduinoTM software. 1 2 3 • In the menu "Tools" (1), select option "Board" (2) and set the type "Arduino/Genuino Mega or Mega 2560" (3). 1 2 3 • 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\RF2000v2\Repetier" • A new window opens.
• In the new window, click the button with the arrow to the right in order to compile and 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. • After a successful firmware installation, the 3D printer will start again and briefly display the new firmware version in the first display line after the start.
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.
25 mm Now tip the printer to the left 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 25 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 Caution: Danger of burns. Do not directly touch the hot nozzle or 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 an 8 mm hexagon wrench or ring spanner (2).
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 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 printing plate: • The temperature of the printing 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 printing 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.
