3W: Paper, wood chips, plastic, leather, fabric, cardboard.
7W: Paper, wood chips, plastic, leather, fabric, cardboard, stone, ceramic, stainless steel, glass, colored acrylic.
12W: Paper, wood chips, plastic, leather, fabric, cardboard, stone, ceramic, stainless steel, coated metal, glass, colored acrylic.

The baud rate for all machines is 115200.

The laser spot size for the devices is 0.04*0.04mm.

Yes, you can engrave on regular cylinders, but it must be used with a laser rotary roller. Engraving on irregular surfaces is not recommended because it is difficult to achieve good results.

Most materials (such as acrylic, wood, leaves, plastic, etc.) can be engraved. Opaque black plastic boards can be cut (note that the cut edges may melt due to high temperatures). For glossy, translucent, or metal materials, they need to be painted black/colored before engraving.

The 3W laser has lower power and can cut thinner paper, leather, and leaves; a 2mm wood board requires multiple passes to cut. It is not recommended to use the 3W to cut wood boards.

Although you can try to increase the power and lower the speed for engraving, the effect is limited. It is strongly discouraged to use a blue laser to engrave metal for a long period, as the laser reflection from the metal can easily damage the core. If you have long-term needs, we recommend purchasing a compatible infrared laser head device.

1. Adjust the laser focus to ensure precise focusing.
2. Adjust the engraving power and speed; you can refer to the material reference table at the end of the manual.
3. Confirm whether the imported image is clear.
4. Check whether the engraving machine is leveled.
5. Clean the dust or debris on the laser lens.
6. Adjust the laser interval to a smaller value (e.g., 0.06mm).

1. Check if the pulleys on the X and Y axes are loose, and fine-tune them via the eccentric nuts (the fit between the pulley and track shouldn't be too tight).
2. Check and tighten the belts and the set screws at both ends.
3. Check if the laser head is wobbling; tighten the screws to keep it vertical, and move the laser head as close to the top as possible to reduce wobbling.

The laser's moving distance depends on the parameter settings. Please check if the parameter settings match the movement; the set size of the picture should be equal to or smaller than the size of the engraving material.

The laser head needs to decelerate every time it changes direction, which can cause scorched edges. Please lower the minimum power setting or use the M4 dynamic power mode (enable configuration parameter s32, set to s32=1).

Please ensure a 2 mm distance is maintained between the laser module and the object to be engraved. You can use the 2 mm plastic board included in the accessories to assist with the adjustment.

Please use a honeycomb laser bed, or elevate the wood board to keep it hollow. Avoid placing it directly on a flat steel plate to prevent laser reflection from causing scorching.

1. Check if the machine is turned on and the power supply is connected properly.
2. Recalibrate the laser head focus, and check if the lens is blurry or dusty; clean or replace the backup lens if necessary.
3. Appropriately increase the power and decrease the speed.
4. Check the material; reflective or translucent materials need to be colored.
5. Prolonged use at full power may cause damage; it is recommended to set the daily maximum power to 90%. If a test confirms the laser head is faulty, please contact customer service.

1. Check if the blue laser was mistakenly used to engrave white, highly glossy, reflective, or smooth metal materials (strong reflection will damage the laser core).
2. Use the test file to test; if hardware damage is confirmed, please contact customer service.

1. Check if cluster mode is turned on.
2. Place the machine on a flat table, and press and hold the green power button for 15 seconds to restart and reset the device.
3. If a limit is triggered (stuck on the X or Y axis), you need to manually release the limit and then click reset.
4. Flash the latest firmware or check if the motherboard is damaged.

This is a normal phenomenon. The light spot emitted by the blue diode laser is a rectangle close to a square. When moving in different directions, the angle between the long side of the spot and the movement direction varies, causing a slight change in energy distribution.

The laser did not home before engraving, or the picture size exceeded the engraving area. Please click the "Home" button on the program interface to move the laser to the bottom left corner. If the image size is too large, please modify the image size to fit within the working area in the parameter settings.

1. Check if the motor cable has a poor connection.
2. Follow the installation video to recheck the assembly step by step and adjust the tightness of the belts and eccentric wheels.
