Ruida is one of the most widely used controllers in the laser cutting and engraving industry. Known for its reliability, intuitive interface and compatibility with many programs, it is pre-installed in most Wattsan laser machines. Regardless of whether you are new to Ruida, understanding how to operate the controller will help you work more efficiently.
In this article, we will tell you about the main functions of the Ruida controller, in particular, the RDC6445G/S version, explain the screen layout, button functions and workflow so that you can use your laser machine with confidence.
About the Ruida RDC6445G/S controller
The RDC6445 is the latest version of the Ruida controller, which comes in two versions: G and GZ. In Wattsan, we install version G, which provides full compatibility with auxiliary equipment.
This controller is designed for smooth integration with CO2 laser machines and provides real-time control of laser parameters, positioning and file management.
The LCD screen and its layout
The control panel is equipped with a 5-inch color LCD display with multiple function zones, which gives you a complete overview of the work being done.
- Left side: displays a preview of the processed file in real time.
- Upper right corner: displays the file name, laser power, speed, and current X/Y coordinates.
- Lower right corner: displays the settings for each processing layer (speed, power, etc.), which can be adjusted directly from the panel.
- Bottom line: the information panel displays the serial number of the job, the current state of the machine, the completion time and the status of the connection to the PC.
When the controller is locked, all keys become inactive. To continue, you must enter the password to unlock the interface.
Navigating the keypad and buttons
To the right of the display, you will find a numeric keypad used to enter values, as well as buttons for moving the laser head and navigating the menu.
- Z Up/ Z Down: Adjust the height of the lifting table or turn on the autofocus if it is set.
- U+ / U−: rotation of the connected rotation axis or conveyor system.
- Center button: Switches between continuous and interval modes of moving the laser head. Continuous mode is the default mode in which the head moves when a button is pressed. The interval mode moves it by a fixed distance and must be set manually via the menu.
To set the travel interval:
- Press the Menu button
- Go to Functions > Manual Settings
- Press the Read button, enter the desired distance in mm using the numeric keypad and confirm with the right mouse button.
Understanding and using the buttons in workflow
Let’s look at a typical operation using a Ruida controller.
Loading and selecting a file
Click the File button to access the controller’s memory. Use the up/down arrows to scroll through the saved files. The built-in memory (128 MB) is enough to store hundreds of layouts.
To download a file from a USB drive:
- Select the U-disk+
- Click “Read the file from the U disk”
- Select the desired file and click “Copy to memory”
Note: Do not confuse the USB port for a flash drive with the port for connecting to a PC — they are not interchangeable.
Adjusting power and speed
Once your file is downloaded, press Enter to open the settings menu. Select the desired layer and adjust the speed and power values. They can also be changed during processing.:
- Speed: adjusts the head movement speed
- Power: changes the intensity of the laser radiation
- Pulsed: Sends single laser pulses, usually for alignment. By default, the pulse duration corresponds to the time when the button is pressed, but it can be set in milliseconds in the menu.

Move the laser head to the desired starting point and press the Origin button. This will keep the position as the starting position for the new assignment.
To visualize the processing area, click the Frame button.
This will outline a rectangle that will be processed based on the outer edges of the file, rather than the exact shape.
Use the focus button if your device is equipped with an autofocus head. Otherwise, manual focusing is required before starting work.
Starting, pausing, and stopping a job
- Start/Pause: starts or pauses the processing of the selected file. When paused, work can be resumed from the exact stop point — ideal for testing settings.
- Stop: completely cancels the operation and returns the laser head to its original position.
- Reset settings: resets the controller — useful in case of errors.
- Emergency stop (on the machine body): instantly stops all machine functions for safety reasons.
Conclusion
The Ruida RDC6445G controller is an intuitive tool for controlling your CO2 laser machine. From processing files to completing tasks, it provides all the functionality needed by both beginners and professionals. By understanding the layout, button functions, and workflow, you can optimize the laser cutting and engraving process, reduce setup time, and improve the quality of your products.
Mastering the Ruida controller will not take much time, but it will significantly affect the efficiency of using your machine.
