Connect RA2 to your laser engraver

RA2 supports xTool D1 and other open-structure laser engravers.

Connect RA2 to xTool D1

1. Use the risers delivered with xTool D1 to raise it.

mceclip2.png

If you need to raise xTool D1 higher, you can go to xtool.com to purchase more risers.

2. Connect RA2 to xTool D1.

3. Place RA2 in the working area of xTool D1. Ensure that RA2 is parallel to plates of xTool D1.

Connect RA2 to other open-structure laser engravers

Note: The steps in this section are for reference only. The structure and position of the y-axis motor vary according to machine.

1. Raise the laser engraver to a height that allows the laser module to process your material on RA2.

2. Unplug the connection cable from the y-axis motor.

Tips: Generally, an open-structure laser engraver is equipped with two motors, namely the x-axis and y-axis motors. The x-axis motor allows the laser module to move left and right, and the y-axis one allows the laser module to move forward and backward. 

3. Connect the connection cable to a connector adapter delivered with RA2, and then connect the adapater to the device connection port on RA2. 

4. Place RA2 in the working area of the laser engraver.

Use software to operate RA2

Laserbox basic

 
Go to Software for xTool D1 to download the Laserbox basic software applicable to the operating system that runs on your PC.
 

Currently, the Laserbox basic software supports only xTool machines. The following uses xTool D1 as an example to describe how to use Laserbox basic to operate RA2:

 

1. Turn on xTool D1.

2. Set the position of the laser module.

(1) Put the focal length setting bar down.

(2) Loosen the thumb screw on the other side and slide the laser module upward or downward to allow the bottom of the focal length setting bar just to touch the surface of the material.

(3) Put the focal length setting bar back.

3. Set the start point for processing on the material.

By default, red cross light beams are emitted for you to locate where the processing begins.

4. Connect xTool D1 to your computer.

5. Open Laserbox basic and connect your xTool D1.

8. In the Working window that appears, click the Rotary tab and set parameters for rotary engraving.

mceclip16.png

You can select Roller or Jaw Chuck according to the components of RA2 you are using, and then set the speed and distance. 

The blue point indicates where the design element starts to be engraved. You can click to set the start point of the processing on a design element.

9. Click Start and wait for the processing to end.

The rollers of RA2 roll the material for engraving.

LightBurn

 
Note: Ensure that you have purchased, downloaded, and installed LightBurn. 2. Before using LightBurn to operate RA2, ensure that you have updated the firmware through the latest 1.3.0 Laserbox basic.

 

The following uses xTool D1 as an example:

1. After connecting RA2 to xTool D1, connect xTool D1 to LightBurn.

mceclip21.png

2. Import a design file and modify parameters (size of file, laser speed, and power).

3. Choose Tools > Rotary Setup.

Tips: You can click Test to check the rotary settings. See if the rollers or jaw chuck can turn 360 degrees.

Note: Currently, the Mirror Output to Rotary setting on Rotary Setup can't automatically take effect. You need to open the Rotary Setup window and click OK every time before you click Start to start engraving, to make the setting take effect.

5. Click Frame to preview the engraving area. Ensure that the design elements are to be engraved in the expected area.

6. Click Start.

LaserGRBL

Note:

  • Currently, xTool products do not support LaserGRBL.
  • For detailed instructions, go to lasergrbl.com/usage.

1. Connect your machine to LaserGRBL. 

For details, see the user manual of your machine.

2. Import design files and modify parameters.

For the roller mode, you can use the default settings.

For the jaw chuck mode, you need to modify Y-axis travel resolution.

Choose Grbl > Grbl Configuration, divide 12,800 by the circumference of the object to be engraved, and set Y-axis travel resolution to the value obtained.
