Resume Printing

AD-F4 is equipped with a resume printing function to assist you in resuming the print from the point of interruption.

1. After power failure
   After power restored, turn on the printer, click “Accept”
   Please wait the printer resuming.
   After reaching the specified temperature, the printer will automatically transition to the printing interface.
2. After filament run out
   Printer will stop working, and yellow light up.
   Replace new filament into the extruder, click load till the filament was feed out.
   Click “Resume” , continue to print from the point of interruption.
3. Filament Autofeed
   This mode is only available for single-color printing and cannot be enabled for multi-color printing.
   When this mode is enabled, if Filament 1 runs out, the printer will automatically switch to Filaments 2, 3, and 4 sequentially, continuing to print until all filaments are used up.
   

Slicing Software Installation and Usage

Installation:
Search “www.3dmingda.com/download” in any Broswer.
Download “MINGDA OrcaSlicer”

Configuration:

If you are the first time to use MingDa OrcaSlicer, you will enter the configuration wizard.

Usage

Select the filament type; you can select Advanced Mode to unlock more setting parameters.

Click to add up to four filaments and set the corresponding colors.

Create text for printing

1. After creating or importing a vector file, select the model and choose the Horizontal Mirror option.
2. You can adjust parameters in the right panel, including side border shape, height, bottom thickness, and wall thickness.
3. After configuring the parameters, save the file to your computer.

Import print file

Bottom Pattern Settings

1. Click “Strength”;
2.  Set Top Shell Layers and Bottom Shell Layers to 0 to prevent the top and bottom shells from affecting the bottom pattern.
3. In the Infill section, set the Sparse Infill Density to 40% (the density can be adjusted as needed). Choose the desired pattern style for Sparse Infill Pattern.
4.  Click “Others” and set the Brim Type option to Outer Brim Only. This generates only the outer edge of the model to enhance
   its adhesion to the platform.
5. After completing the model parameter settings, click “Slice Plate” to preview the slicing.
6. “Export G-code file”

Side Multi-Color Settings

1. Click Color painting [N]
2.  Select the desired Filaments color
3. Select Height Range
4. Set the Height Range you need
5. After completing the settings, you can proceed to paint directly on the model.

Start the Prime tower
During the printing process of multi-color models, filament switching may leave residual filament from the previous color in the nozzle, causing color mixing issues on the model.
Using a Prime Tower can resolve this problem. Before switching filaments during printing, the nozzle prints a Prime Tower, where the residual filament is deposited. This effectively prevents color mixing during filament transitions.

1. Select the “Multimaterial” section.
2.  Check the “Enable” option in the “Prime tower” settings.

Note: The printing position of the Prime tower cannot coincide with the model

Bottom Multi-Color Settings

Using the example on the right (colors: red, yellow, white, blue):
When exporting the vector file, you can subdivide it into separate files.
For instance:

1. Export the model border as an individual dxf or svg file.
2. Export each of the four colors (red, yellow, white, blue) as separate dxf or svg files.

This approach ensures better management and precise application of each design element during further processing or printing.

Click the icon , then import the created dxf or svg files individually into the AdWordCraft software. Set the parameters as needed and save your settings.

Model Border Parameter Settings

1. Select the desired side shape and adjust the corresponding parameters.
2. Click to disable “Bottom Closed”.
3. Set the appropriate “Wall Thickness”.
4. Select the model and apply a “Horizontal Mirror”.
5. Click “Create” to save the file.

Model Bottom Parameter Settings

1. Set the bottom thickness to 4-5mm, and cancel or set all other parameters to zero.
2. Select the model and apply a “Horizontal Mirror”.
3.  Click “Create” to save the model.

Model File Adjustment
Import the created model files into Mingda OrcaSlicer.

1. Click the button to switch to the “Objects” interface.
2. Double-click the color block to change the model to the desired color.
3. Adjust the positions of the models as needed, moving each to its correct location.
   
4. We need to organize these models to ensure each color is printed correctly.
   You can directly drag and drop the corresponding STL files in the left panel to arrange the models in the desired order.
   
5. After adjusting the order, press [Ctrl + A] to select all the model files. Right-click and choose “Assemble” to group all the model files into a single Assembly.
   
6. Click “Slice Plate” to preview the model. If everything is correct, proceed by clicking “Export G-code File”.
   

Printing

Ensure that the printer and the computer host are on the same local network.

File Transfer:

Click “Print” and choose “Upload and Print.”

Device Connection

1. Task List: Drag G-code files to this task list for printing.
2. Temperature Control: Displays machine temperature changes and allows pre-setting nozzle and bed temperatures.
3. Camera: Monitors the printing status.
4.  Movement Control: Controls the movement of each axis and allows compensation settings after leveling.
5.  Printer Limits: Controls the maximum acceleration of the printer, usually doesn’t need to be changed.
6. Console: Sends G-code commands to run the machine and displays error output.

Maintenance and Care

Cleaning the Nozzle: After printing is complete, promptly clean the residue on the nozzle using a tool and taking advantage of the nozzle’s residual heat. Avoid touching the nozzle directly with your hands to prevent burns.
Replacing Filaments: Timely replace filaments based on the type and actual usage. It is recommended to use filaments recommended by the manufacturer. Seal filament not in use for an extended period, as excessive exposure to moisture in the air can make the filament brittle.
Checking the Platform: Regularly check if the print platform is flat. If there is deformation or damage, contact the manufacturer or dealer for repairs. Regular Lubrication: Periodically apply lubricating oil to the guide rails. During the operation of the printer, friction between various parts occurs. Without proper lubrication, it can lead to wear and damage.
Software Updates: Regularly update the printing software to improve print quality and efficiency.
