Luban's A-B position function only supports 2W Infrared Laser Module and 20W/40W Laser Module.
If you don't want to set the work origin, you can use Luban's A-B position function to accurately locate the engraving area. Select two points (point A and point B) on the material, and Luban software will automatically calculate the engraving area based on the coordinates of points A and B and present it on the canvas.
It is worth noting that AB Position is essentially a generated ordinary G-code, but its work origin is set to the machine coordinate point (0,0). If the work origin is redefined after completing AB position, the work origin of the AB position G-code (i.e., the machine coordinate point (0,0)) will be overwritten. You will need to redefine the work origin to the machine coordinate point (0,0), or you can click the "Done" button on the AB position panel again to automatically set the work origin to the machine coordinate point (0,0). Otherwise, the laser processing may fail.

¶ Procedures
Before using A-B position function, please first connect the machine to Luban.
-
On Luban homepage, click Laser > 3-axis to enter the Laser G-code Generator.
-
Complete the Job Setup and click Confirm.
-
On top hidden bar, click File > Case Library > Metal Tag to import the example case.
- Click A-B Position on the top toolbar.
- Click Turn On to turn the crosshair on.
- On the control panel, click X+/X-/Y+/Y- to control the movement of the toolhead. When the crosshair reaches the target point A on the material, click Set A Position; then move the crosshair to the target point B and click Set B Position. When finished, click Done.
Click the value under the XYZ Axis Offset to adjust the unit distance for the toolhead movement.
-
Drag the model into the rectangle displayed in Luban and resize it if needed.
-
Use Luban's default parameters to generate the G-code file.
-
Click Export Load G-code to Workspace.
Select to read the corresponding content in accordance with your machine model.
（1）Click Start On Luban.
（2）Select Input Material Thickness mode or Use Work Origin mode.
- Input Material Thickness：
Manually enter the thickness of the material and the machine will automatically adjust the laser height according to the material thickness of that you enter. When finished, click Start to do the job.
The thickness of the provided Metal Tag is 1.2 mm.
- Use Work Origin：
First release the focus lever by rotating the knob counterclockwise. In the right control panel, click Z+/Z- to move the toolhead until the focus lever touches the material and the horizontal line above the knob aligns with the scale Focus. Retract the focus lever and lock it by rotating it clockwise. When finished, click Start to perform the job.
Be sure to wear laser safety goggles before starting work.
(1) Click Send to Device to send the G-code to the device.
(2) Select the G code file on Touchscreen and click Next to enter Adjust Laser Height interface.
(3) Follow the instructions on Touchscreen to adjust laser height. When finished, click Next to enter the Set Work Origin interface.
(4) Once in the Set Work Origin interface, make sure that it is in the Advanced Mode, then the machine will automatically use the work home position set in Luban.
If it is not in the Advanced Mode, please switch to it in the top right conner of Touchscreen.
Before start, you can click Run Boundary to confirm that the engraving area is accurate.
(5) Click Start Job.
Be sure to wear laser safety goggles before starting work.
（1）Click Start on Luban.
（2）Select Input Material Thickness mode or Start From Work Origin mode.
- Input Material Thickness：
Manually enter the thickness of the material and the machine will automatically adjust the laser height according to the material thickness of that you enter. When finished, click Start to perform the job.
The thickness of the provided Metal Tag is 1.2 mm.
- Start From Work Origin：
First release the focus lever by rotating the knob counterclockwise. In the right control panel, click Z+/Z- to move the toolhead until the focus lever touches the material and the horizontal line above the knob aligns with the scale Focus. Retract the focus lever and lock it by rotating it clockwise. When finished, click Start On Luban > Start From Work Origin > Start to perform the job.
Be sure to wear laser safety goggles before starting work.
（1）Click Send to Device.
（2）Find and select the received G-code file.
（3）Select the Focus Lever - Assisted Mode.
（4）Follow the instructions on Touchscreen to adjust laser height.
Once in the Set Work Origin interface, the machine will automatically use the work home position set in Luban.
（5）Click Start to perform the job.
Before start, you can click Run Boundary to confirm that the engraving area is accurate.
Be sure to wear laser safety goggles before starting work.
（1）Adjust the laser height.
（2）Click Run Boundary and then press the work switch to verify the machining area corresponding to the current working origin. If it does not match the expectation, you can continue adjusting the position of the work origin or rotating the material.
After you click Run Boundary in Luban, a run-boundary file will be generated and transferred to the machine. When you press the work switch, the machine will run the boundary based on that transferred file.
If the laser module bumps into the machine, press the emergency stop button or turn off the machine immediately.
（3）Click Upload Job. Once the transfer is successful, Luban will display a notification.
Each time you transfer a new G-code file, the previously transferred file will be replaced in the microSD card.
（4）Check the state of the Enclosure.
- IF you have installed the Enclosure, make sure the Enclosure door is closed and will stay closed throughout the task.
- IF the Enclosure is not installed or purchased, be sure to turn off Door Detection in Luban's Workspace > Settings in the top menu bar. Otherwise, the machine will not start the task.
（5）Press and hold the work switch on the integrated controller until the machine starts the task.
Keep the machine attended throughout the task!
During laser machining, you can control the task using the following methods:
-Work switch: Press to pause/resume; Press and hold to stop.
-Luban: Click Pause/Resume/Stop to perform the corresponding operation.
