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

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 switch
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.
First 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.

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

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.
1.Right-click Frame and click Edit button.
2.Set to S0

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.
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 A40 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.

Step 9 FAQ
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".
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.
