Software
The RDC6442S software is compatible with several software programs such as RDWorks, LaserCut, and LightBurn. These software programs provide users with a user-friendly interface for designing and executing laser jobs.
RDWorks is the official software for Ruida controllers and is widely used in the industry. It provides users with a comprehensive set of tools for designing and executing laser jobs, including support for vector and raster graphics, automatic optimization, and camera alignment.
LaserCut is another popular software program that is compatible with Ruida controllers. It provides users with similar tools to RDWorks and supports a range of file formats, including AI, DXF, and BMP.
LightBurn is a third-party software program that is compatible with Ruida controllers. It provides users with a modern and intuitive interface for designing and executing laser jobs. It also has advanced features such as camera alignment and automatic job optimization.
Firmware Upgrade
The Ruida RDC6442S controller is a popular controller used in laser engraving and cutting machines. If you want to upgrade the firmware of your Ruida RDC6442S CO2 laser controller, follow these steps:
- Download the latest firmware from the official website or a trusted source.
- Connect the controller to your computer using a USB cable.
- Open the RDWorks software and go to the “System” tab.
- Click on “Firmware Upgrade” and select the firmware file you just downloaded.
- Follow the instructions on the screen to complete the firmware upgrade process.
It is important to note that you should only upgrade the firmware using the official software and from a trusted source. Improper firmware upgrades can cause issues with the controller and may void the warranty.
V8.01.67 Optimize the 3-color light logic, Optimize the encryption algorithm
Release notes: The latest version is 8.01.67; 8.01.67 is for RDC6442S. 8.00.67 is for RDC6442G. The difference between the RDC6442S and RDC6442G is little. RDC6442S support 2 laser heads and can locate the positon of laser heads according to the cutting task automatically. RDC6442G does not support that.
