CO2 lasers are powerful and precise tools that are often used for cutting and engraving. However, users, especially beginners, sometimes encounter a typical problem when the machine design changes during operation. Don’t worry if you’ve encountered this problem. The answer is simple, and in this post we will tell you about it step by step.

Why the mirroring happens
It is very important to understand the cause of the problem before attempting to fix it. Pay attention to the initial movement of the laser head when you turn on your laser machine; this is the starting point. Now, launch RDWorks or the control program of your choice. Study the diagram; the initial software configuration is displayed as a tiny green square on the screen.
When using simple settings, this first setting is usually located in the lower-left corner. However, if your computer is physically set to start from a different corner, such as the upper-right corner, this software-hardware mismatch can result in mirrored or inverted graphics. Since the software uses a different starting point than the machine’s settings, the image of the workpiece is displayed upside down. This is a common setup issue, especially for individuals with limited knowledge. If you are working with a Wattsan CO2 laser machine, we offer training and support services to help you avoid these issues and set up your equipment correctly from the start.

It only takes a few simple steps in the software to fix the mirroring issue. Here’s how to do it in RDWorks:
- Launch RDWorks and open your current design project.
- In the top menu bar, go to the “Config” tab.
- Select “System Settings” from the drop-down menu.
- A new window will open. Here, focus on two important sections:
- Homing position
- Position of the laser head
- Match the homing position in the software with the actual location of your laser head. If your machine is in the upper-right corner, set the homing position in RDWorks accordingly by selecting the option in the upper-right corner.
- Click OK to save the new settings.
- Now re-import or send your project to the machine controller.
- Perform a quick check to make sure that the drawing is properly engraved or cut without mirroring.
This setting should completely eliminate the mirroring issue.

Conclusion
Mirrored images on your CO2 laser machine can be frustrating, but they are usually caused by a direct mismatch between the software and your machine’s original settings. You can ensure accurate results by configuring RDWorks to match the actual aiming position of your machine. Don’t hesitate to contact your supplier or technical support team if you still have any issues or questions regarding the settings. Wattsan provides specialized instructions and remote support to help you work efficiently and confidently.
