**Part-II** **Chapter 2 ( 3D Printer)** Safety Instructions =================== Contents 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. Technical Specification ======================= Printing Parameters: -------------------- Temperature Parameter --------------------- Software Parameter ------------------ Electrical ---------- Physical Parameter ------------------ Part List =========  Product Overview ================  3. Menu Directory ============== 1. :Home menu: 2. :APPCATION menu:   3. :SYSTEM menu: 4. :PRINT menu:  Assembly instructions ===================== : Components assembly steps: ---------------------------- **(Figure 1)**    **(Figure 6)** **Step 7**: Install the top Aluminum(AL-5) as shown in **Fig.7**.  **(Figure 8)** **(Figure 9)** : Main board wiring diagram as shown in Fig.10. -----------------------------------------------  : Select the correct voltage mode according to your local voltage ratings(110V/220V).The switch is on the power supply which inside the base box as shown Fig.11.(Factory default is 220V) ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ :Filament installation ---------------------- **(Figure 12)** - Only insert filament into the hotend after "Preheat" it later. - It is suggested to cut off the bent tip of the filament, and rotate the filament if feels any resistance during installation. - It is important to make sure there is no tied or tangle on the reel. Leveling instructions =====================   - Now, as the temperature rises, please manually insert the filament through the Teflon tubing all the way into the hotend. (Refer to previous **Fig.12**) - The filament should flow through when temperature reaching to over\~180-190°C, otherwise the filament has not been inserted properly. - Customers may use tweezers to carefully remove the extruded filament at the nozzle tip before printing. There might be 3 kinds of results for the first layer of the test prints (**Fig. 17**).  Step 7: The supplementary instructions for Leveling (this step is not normally required) ---------------------------------------------------------------------------------------- 1. Adjust the 4 nuts under the platform, let the height in-between the support plate and the heat bed is a suitable distance for all the 4 corners (Suitable distance means the heat bed must be horizontal)as shown in **Fig.18**. **(Figure 18)** 2. As shown in **Fig 19**, Loosen Z adjustable nut(Refer to previous **Step 1**) by X mm if nozzle is lower than the platform (X is defined by how much the nozzle is under the platform), while Tighten it by Y mm if nozzle is too high from the platform (Y is defined by how much the nozzle is above the platform). It may need adjustment for few times. 3. On Home menu,click\"APPCATION\" \>\"LEVELING\" then home to verify the results. After this, please level the Cura Instructions ================= :Cura Installation ------------------   : Cura settings --------------- 1. **Machine settings**  Basic and Advanced options --------------------------  **(Figure 23)** Plugins ------- Start/End-GCode ---------------  **(Figure 25)** : Load 3D model into Cura ------------------------- 1. Clear the platform by clicking "File"\-\--\>"Clear platform" 2. Load 3D files onto the platform by "File"\-\--\>"Load model file...". Files with extension such as "STL", "OBJ", "DAE" and "AMF" can be loaded. :Manipulate 3D model in Cura ---------------------------- 1. Zoom in/out: scroll the mouse wheel 2. Change viewing angle: right click the model, hold on and move the mouse 3. Position change: left click on the model, hold on and drag the model to move. 4. Rotate: single left click on the model and several icons will appear at the bottom left of the window (**Fig.26**). Click the rotate button, 3 circles will surround the model. Rotate the model by moving the circle lines. - Lay flat: it is very impartant to ensure the flat portion of the model is well attached to the platform. So, please use Lay Flat option everytime after rotating the model, as it will minimize the adhesion issues during printing(**Fig.26**). - Reset: click it to return the model to the original orientation. 5. Scale: to uniformly scale the model along X/Y/Z dimensions. To disable uniform scaling, click the lock in the lower section of the scaling window. (**Fig.27**) **(Figure 27)** 6. View mode (**Fig.28**): to view the model in different ways and helps to spotting issues before print starts. Such as "Layers" mode: to view the toolpath of the print head to check if there are skipped layers or gaps.  :Save GCode in Cura ------------------- - Re-open the Gcode file again in Cura to confirm that all slices of the model have been included by check it in the "Layers view" (refer to previous **Fig.28**). - The file name should only contain English letters, underscore and space. File name contains special characters could not be recognized by the printer. ------------------------------------------------------------------------------------------------------------------------------------------------------ 3. Wire diameter: The diameter of the selected wire is 1.75mm 4. Nozzle size: Nozzle diameter is 0.4mm 5. Printing speed: 50-60mm/s is recommended, it should not be set too fast, too fast will affect the printing accuracy 6. Shell print speed: Reduce the print speed of the outermost layer to improve the flatness of the model surface Online printing Instruction =========================== 7-1. Driver installation for online printing -------------------------------------------- - Firstly, power on the machine and connect it to PC via USB cable. - CH341SER driver is copied in the SD card. "Programming software and Driver"\-\--\> "CH341SER". Right click\"CH341SER\" on your computer to install the driver as shown **Fig.30**.  7-2. Cura settings for online printing -------------------------------------- - If the PC has been installed CH341SER driver before, then there should be a COMx in Ports of Device manager already. - Sometimes, even the driver is not installed properly, it may still show an abnormal COMx in Ports, please just  7-3. Print online by Cura ------------------------- 1. After parameter settings, customer can print online by Cura with USB connection. Click "File"\-\--\>"Print..." as shown in **Fig.32**. 2. After click\"Print...\",it will appears the printing windows as **Fig.33**.Then the temperature would rise and it will start to print when reaching to the target temperature. Offline Printing Instruction ============================  Change Filament Instruction =========================== - Make sure the filament passes through the filament sensor first before reaching into the extruder. - For easier feed in the filament, it is suggested to cut off the bent tip before insert.  Resume From Outage ==================  **(Figure 37)** 3. Insert the SD card,Print the just saved file (i.e."test.gcode"). The machine will automatically heating on and print. \*Note: ------- - In order to get smooth surface, use tweezers to carefully remove the excessive filament at nozzle before continuing print upon the last point. - DMSCREATE DP-X 3D printer supports resume from outage only when print offline - Due to the differences of filaments, temperature, extrusion, etc...we could not guarantee a perfect surface at the point of "Resume from outage", especially for small object. Trouble shooting ================ Not extruding at start of print ------------------------------------------------------ 1. Extrusion is not working 2. Ensure that the nozzle temperature has been set to match the filament 3. Nozzle is too close to the heat bed 4. Nozzle clogged please try to replace it or clean it 5.

The motor cable are not connected properly, check each connection and then inspect the cable routing for any faults File not printing or SD card failure ------------------------------------ 1. Remove the SD card and insert into PC. Open the Gcode files using text editor (eg. Notepad), and inspect if Gcode is readable or not. If files contains of multiple 2. SD card is not readable, ensure file name does not contain special characters or Change SD card 3. Reboot the machine and try again Print stopped halfway --------------------- 1. Check if the Gcode file is corrupted 2. Delete plugins in the Gcode file 3. Use print offline mode (SD card) instead of print online via USB Touch screen no response ------------------------ 1. Inspect if the touch screen has been pressed by the metal frame at the edge 2. Check if the cables and wires which connect the screen are loose 3. Check if the screen was broken,if so,please contact our service team
