Packing List

Step 1 Connect the Z-Axis and Slider to the Machine

Option 1 Connect the Z-axis and slider to the machine from the back.

Option 2 Connect the Z-axis and slider to the machine from the front.Option 3 This type of Z-axis does not require replacement and can be inserted directly into the laser head.

Step 2 Replace the control box

Method 1 The trial installation control box is paired with the hole position before the type, and the control box is directly installed.

Remove the original control box and cable| Install the control box in the manifest

Method 2 The trial control box is not matched with the hole position in front of the type, and it is necessary to wear a T-nut and lock two M5*8 screws.

Install the control box in the manifest| Install the T-nut| Tighten the screws

Step 3 Connecting cables

Note: To use the original laser head, there is no need to disassemble the control box again. Simply connect these two wires together.

Step 4 Test Process – Power On

1. Turn on the machine power switchFirst turn on the power switch of the machine, and then turn on the switch of the fiber laser control box to avoid the probability of random emission for about 2 seconds after power-up.
2. Focus Adjustment

1. Position the test material on the machine.
2. Observe whether the red light spots at the left and right ends of the laser head overlap. If not, adjust the height by rotating the knob on the Z-axis to make the two spots coincide.Focal length is 94-96 mm.

3. Laser Frequency Adjustment
   The frequency of the control box can be adjusted from 30kHz to 60kHz. Refer to the parameter table for adjustments.(pp. 16-19)

Step 5 Testing Process – Use on PC

1. When using Lightburn for online or offline engraving of images and pattern filling, it is recommended to enable overscanning for better engraving results.
2. Refer to the machine’s user manual for instructions on how to use Lightburn. The only difference is in the framing process. For framing in Lightburn, select “Move” > “Power” and set it to 0. You can monitor the framing process through the red light indicator.
3. Refer to the machine’s user manual for instructions on how to use LaserGRBL. The only difference is in the framing process. When performing framing in LaserGRBL, the framing energy needs to be changed to 0.

Step 6 Testing Process – Offline Use of K1 Machine

1. When using a blue laser offline with lightburn, click on “Edit” and select “Machine Settings.” Change the PWM min value ($35) from 0 to 1. Note that $35 of FL20 should be set to 0 and that of blue laser should be set to 1.
   If the $35 and $60 commands do not appear in the software, the machine firmware needs to be updated.

2. When using a blue laser offline with GRBL, click on “Grbl” and select “Grbl Configuration.” Change the $35 value from 0 to 1.
   Note that $35 of FL20 should be set to 0 and that of blue laser should be set to 1.

Step 7 Testing Process – Offline Use of X40 Pro Machine

1. When using a blue laser offline with lightburn, click on “Edit” and select “Machine Settings.” Change the PWM min value ($35) from 0 to 1. Note that $35 of FL20 should be set to 0 and that of blue laser should be set to 1.
2. When using a blue laser offline with GRBL, click on “Grbl” and select “Grbl Configuration.” Change the $35 value from 0 to 1.
   Note that $35 of FL20 should be set to 0 and that of blue laser should be set to 1.

Step 8 Testing Process-Offline use without machine shipment

1. lightburn: When using a blue laser offline, click on “Edit” and select “Machine Settings.” Change the PWM min value ($60) from 0 to 1. Note that $60 of FL20 should be set to 0 and that of blue laser should be set to 1.

2. GRBL: When using a blue laser offline, click on “Grbl” and select “Grbl Configuration.” Change the $60 value from 0 to 1.
   Note that $60 of FL20 should be set to 0 and that of blue laser should be set to 1.

3. lightburn Engraving power settings : Power Max(%) > 10%, refer to the parameter table for specific values. Please note: Engraving vector mode should be set to “M3 mode”. Follow the steps below to operate: “Cuts / Layers” -> “Line” -> “Constant Power Mode”.

Step 9 FAQ

1. If the engraving or cutting effect is not satisfactory:
   a) Check if the laser is in the focal position.
   b) Check the cleanliness of the lens.

2. If there is a malfunction with the red light indicator and it is inconvenient to check the focal distance through overlapping red lights, you can adjust the focal distance through fixed focus method (distance from laser end face to the measured object: 96.1mm/94.1mm).

3. If there are no traces or uneven energy in the engraved vector lines:
   a) Check if the laser is in the focal position.
   b) Confirm if it is operating in M3 constant power mode.

Remark：

1. Our parameter list is only for the most widely used materials. Customers may need to try other uncommon materials by themselves, or they can contact us to apply for testing.
2. Line mode for vector lines requires M3 mode
