RDV Print Driver User Guide

1. Important Notes

• Safety Warning: Laser processing is a high-risk operation. Do not operate the machine without supervision.
• System Requirements: Supports Windows 7 and above only (macOS not currently supported).
• Communication Interface: Supports direct USB cable connection only.
  

  If you are using a TITAN machine, you need to open the right door panel and connect the USB cable directly to the controller to ensure proper communication.
  If you need to run the machine with the door open, please press the black button on the door sensor checking board to bypass the door safety protection.

• Language Support: Dual-language interface available in Chinese and English.
• Supported Machines: Laser machines with Ruida controllers only.
• Layer and Offset Compensation (Scanning Offset):

Engraving Layer: Supports only a single engraving layer.
      If "Bidirectional Engraving" is enabled, ensure the correct Scanning Offset value is set at the corresponding speed to prevent ghosting or misalignment.

Cutting Layer: Supports multi-layer settings, allowing different cutting parameters to be distinguished by color.

• DPI setting: DPI settings are not available in the RDVPrint driver.

2.3. RDVPrint Document Properties

2.3.1. Layout

Select a paper size smaller than the machine's working area. Otherwise, the machine will beep and stop during processing.

2.3.2. Paper / Quality

Select the "Color" mode to ensure the graphic data is transmitted completely and correctly to the controller.

2.3.3. Output

• Cut settings:

Set the max and min power, speed, and frequency parameters for the cutting layer.

• Engrave settings:

Set the power, speed, and frequency parameters for the engraving layer.

• Union Objects:

During engraving, multiple independent graphic objects are processed as a single unit.

• Unidirection:

The laser head engraves only in one fixed direction (typically left to right or bottom to top). During the return movement, the laser is off.

When this option is not enabled, bidirectional engraving is used, meaning the laser fires in both directions.

The relevant scanning offset parameters can be found on the gold card included with the machine.

 

• Top to bottom:

Engraving scan direction order. When not selected, the default scanning direction is from bottom to top.

• Stamp:

This feature is only available when the output color is set to black and white.

When "Cut off" is enabled, you can choose an Ellipse or Rectangle as the outline and set the corresponding cutting parameters, allowing the engraved design to be cut out in that shape.

If "Co-work with RDCAM software" is selected, the system will automatically switch to RDWorks after clicking Print.

If RDWorks is not installed, enabling this option and clicking "Print" will not open the print window, and the software will remain on the design screen.  

• Programmed coordinates:

The reference origin can be understood as the alignment anchor point for the current graphic relative to the workbench, serving as the baseline position for determining the graphic's placement on the work table.

• Negative:

This option keeps the object itself and processes the area outside the object.

If the design has a black-filled graphic on a white background, the file sent to the machine may appear blank.

In most cases, this option should remain unchecked.

• Scale:

Allows resizing the design while keeping its original proportions unchanged.

• Laser timing:

This function compensates the laser firing timing at the start and end of motion to improve engraving or cutting results.

Laser on ahead: The laser turns on slightly before the laser head fully reaches the start point,

Laser off delay: The laser turns off slightly after the laser head fully finishes the current path.

• Inner path first:

When a design includes both inner paths (such as holes or cutouts) and an outer contour, the inner paths are processed first, followed by the outer contour.

End to end: During processing, when determining the next processing path, the system prioritizes selecting the path closest to the endpoint of the current path.
Center to center: Based on the geometric center points of each path, the system selects the paths whose center points are closest to each other for processing.

• Auto flatten:

This reduces pauses and vibration at corners, making motion smoother and more continuous, which improves overall engraving or cutting quality.

• Reverse path optimize:

Without changing the shape of the design, the controller intelligently adjusts the processing direction of some paths (forward or reverse) to achieve smoother and more efficient motion.
This option is recommended for files with many shapes or complex paths.

• Control model:

There are three control modes: RDCAM, KT, and EAGLE. Only RDCAM is compatible with the RDVPrint driver.

If KT or EAGLE mode is selected, a "Communication error!" message will appear when downloading files.

• Home position:

The actual physical location of the (0,0) point in the machine coordinate system on the work table.

Thunder laser's machine origin position defaults to the top left corner.

If the origin position is set incorrectly, a mirrored effect will occur during processing.

• Laser frequency:

When this feature is enabled, you can set the frequency values for the cutting layer and engraving layer.
If this option is not checked, the machine will process using the default frequency setting.

If the frequency option is not checked and no frequency is set, the machine will process using the default frequency after the file is downloaded.
If a frequency has been set previously, the machine will still use the last set frequency even if the frequency option is not checked later.

So we recommend reading the machine's frequency settings in LightBurn or RDWorks before making any changes, and taking a photo to save them for reference, in case the original values are forgotten.
