BASIC INFORMATION

This manual is a designated user guide engraver for cabinet laser

installation, setup, safe operation, and maintenance. Covers general

information, safety instructions, installation steps, operating instructions,

maintenance procedures, and contact information.

All personnel involved in the installation, setup, operation, maintenance,

and repair of this machine should read and understand this manual,

especially its safety instructions. Some components have extremely high

voltages and/or generate powerful laser radiation. Substandard

performance and longevity, property damage, and personal injury can

result from not understanding and following these instructions.

Your laser engraver works by emitting a powerful laser beam from a

glass tube filled with insulating carbon dioxide (CO2), reflecting that beam

off three mirrors and reflecting it through a focusing lens, and using this

focused light to etch the design onto certain substrates. The first mirror is

fixed near the end of the laser tube, the second mirror travels along the

Y-axis of the machine, and the third mirror is attached to the laser head

traveling along the X-axis. Since some of the dust from the engraving

process settles on the mirror, it needs to be cleaned frequently. Since they

move during operation, they also need to be readjusted periodically with

the set screws to which they are attached to maintain the correct laser path.

A water-cooled system (usually a pump or cooler) must be used with this

engraver to dissipate the heat generated by the laser tube. Similarly, an

exhaust system (usually an external vent or a dedicated air purifier) must

be used to remove the dust and gases generated during the engraving

process.

Running your laser consistently above 70% of its maximum power rating

will significantly shorten its lifespan. It is recom-mended to set at 10-70% of

the maximum rated power for optimal performance and longevity

Please note that this is a high-voltage device and for safety reasons, it is

recommended to only touch its components with one hand at a time during

use.

Note that active lasers are invisible to the human eye. This appliance

- 6 -

should not be used with any lid open to avoid potential permanent injury.

It should also be noted that both the cooling water system and the exhaust

system are absolutely necessary for the safe use of this equipment. Do not

operate the engraving machine without these two systems functioning

properly. The water should always be clean and kept around room

temperature, and the exhaust system should always comply with all laws

and regulations applicable to the workplace and ambient air quality.

The following symbols are used on the label of this machine or in this

manual:

These items carry a risk of serious property damage or personal injury

These projects solve similar serious problems related to laser beams.

These projects solved similar serious problems with electrical

components.

Anyone around the unit should wear protective glasses during operation.

- 7 -

The machine is suitable for engraving logos and other consumer

products on applicable substrates. This laser can process a variety of

materials, including wood and cork, paper and cardboard, most plastics,

glass, cloth and leather, and stone. It can also be used with some

specially coated metals. Use of this system for purposes or materials

other than those for which it is specified is not permitted.

The system must be operated, maintained, and repaired by a person who

is familiar with the field of use and hazards of the machine and engraving

materials, including its reflectivity, electrical conductivity, potential for the

production of harmful or combustible fumes, etc.

Laser beams are dangerous. The manufacturer and/or seller shall not be

liable for any improper use of this device or for any damage or injury

that have been driven into the soil at least 5 feet (1.5 meters) from the

machine.

Poor grounding can lead to equipment failure and create a serious risk of

electric shock. The manufacturer and/or seller shall not be liable for any

damage, accident or injury caused by a poor grounding connection.

4. UNPACK THE ENGRAVING MACHINE.

Your engraver comes in a wooden case with its accessories (including

this manual) packed in the area behind the front through door. You

should place the crate in a generous, flat area for unpacking, and ideally,

you plan to operate the machine permanently.

- 29 -

Step 1: If you haven't already done so, finish removing the crate from

around the engraver. Then roll the machine into place.

Step 2: Hold the brake pads in place by pressing the brake pads on the 2

front wheels.

Step 3: Retrieve the access key from the main bay at the front of the

machine. Remove the accessory bag from the area behind the front

through door. Check that you have received all of the following items:

power cord, ground cable, USB and Ethernet cables, USB flash drive

with engraving software, exhaust pipe with hose clamp, set of hex

wrench, acrylic focusing tool, keys, and this manual.

Step 4 : Carefully inspect the assembly of the laser tube, the viewing

window and the rest of the machine. The laser tube is a highly fragile

object and should be handled with care and as few bumps as possible.

Step 5: Inside the main bracket, remove from the X-axis and the

honeycomb table.

Step 6: You can keep the packaging for future returns, but if you dispose

of it or any accessories, be sure to follow the applicable waste disposal

regulations.

5.MAIN POWER CONNECTION.

Confirm that the label next to the connected outlet on the machine

matches your power supply. Connect one end of the main cable to a

connection socket and the other end to a grounding socket. Under no

circumstances should you turn on the device if the voltage does not

- 30 -

correspond.

Fluctuations along the line should be less than 10%. If this value is

exceeded, the fuse will blow. They are located in the connecting socket

and are externally accessible. Again, do not connect this device to a

standard extension cord or power strip. Connect it directly to a grounding

outlet or use a surge protective device rated over 2000J.

6.WATER-COOLED INSTALLATION.

The supplied water pump is critical to the performance and service life of

the engraving machine. When such a laser works without a properly

maintained cooling system, its glass tube can explode due to

overheating.

Never touch or adjust the water supply of the engraving machine while

the pump is plugged in.

To use the water pump, fill a dedicated tank with at least 2 gallons (7.5

liters) of distilled or purified water This will gradually reduce the quality of

the engraving machine and may even lead to dangerous mineral

accumulation.Cooling system. For the same reason, never use

all-purpose antifreeze. Use custom laser-safe formulations or storage

Engraving machines in climate-controlled areas.

Note：Distilled water or purified water must be added, not tap water

or sewage, otherwise it will reduce the service life of the

product.

Please rotate to remove the dust cover of the water inlet, and then add

purified water or distilled water to the water inlet for the engraving

machine. The green range of the water level line is the safe water level,

and then you can fill the water nozzle dust cover, and then turn on the

- 31 -

main power supply and water circulation switch of the machine.

Note: The water level should not be too full, so as not to overflow the

water cooler.

Water inlet

Before starting the laser, be sure to obtain visual confirmation that water

is flowing through the laser tube.

Never let the water in the tank become too hot to cool the laser. Install a

heat alarm or check the water temperature regularly during extended

use. If the water starts to reach 100 ° F (38 ° C), replace it with cooler

water. During this process, either the laser is replaced in phases or the

laser is turned off: never allow the laser to operate without a con stant

flow of cooling water.

7.INITIAL TESTING.

EMERGENCY SHUTDOWN.

Due to the risk of fire and other hazards during the engraving process, the

engraving machine includes a large, easy-to-reach emergency stop button

- 32 -

near the control panel. Press it to stop the laser tube immediately.

When your engraver arrives, its emergency stop has been pressed and

must be rotated to the right and bounce upwards for the laser to work.

Before using the machine for any other work, you should test if it is working

properly. Start the water cooling system, place a piece of laserable scrap

on the work bed, close the lid, and press PULSE to fire the laser. Press

the emergency stop button and observe if the laser stops immediately. If

the laser continues to fire, the emergency stop does not work and must be

replaced before using the engcher. Turn off the machine and contact

customer service.

LID CLOSURE (INTERLOCK).

Due to the risk of blindness, burns, and other injuries from direct exposure

to the invisible engraving beam, the device

also automatically shuts off the laser when the protective cover is raised

during operation.

After making sure that the emergency stop button is working properly, you

should also test that the cover closure is working properly before doing any

other work on the machine. Start the water cooling system, place a piece of

laserable scrap on the work bed, close the lid, and press PULSE to fire the

laser. Release the button. Be careful not to expose yourself to or be hit by

any possible reflected lasers, open the lid as little as possible and try to fire

the laser again.

Note:If the laser is emitted, the automatic shut-off does not work and must

be repaired before using the engraver. Turn off the machine and

contact customer service.

WATER CUT-OFF.

Due to the dangers posed by uncooled laser tubes, the engraver also

automatically shuts down the laser when the water cooling system fails.

After making sure that both the emergency stop button and the lid protection

- 33 -

are working properly, you should also test that the water cut-off is working

properly before doing any other work on the machine. Start the water cooling

system, place a piece of laserable scrap on the work bed, close the lid, and

press PULSE to fire the laser. Release the button. Cut off the flow of water by

curling or tying two hoses. Be careful not to damage the hose itself during this

process. Try firing the laser again. If the laser is emitted, the automatic shut-off

does not work and must be repaired before using the engraver. Turn off the

machine and contact customer service. If the laser does not emit, the

automatic shut-off works fine; Simply loosen both hoses to start circulating

water again and continue setting up the engraver.

LASER PATH CALIBRATION.

While our factory calibrates your entire system during assembly, the laser tube,

focusing lens, and/or one or more mirrors may be pushed out of alignment

during shipping. Therefore, it is recommended that you perform an optical

alignment-test when setting up your machine. For step-by-step guidance, see

the maintenance section below.

AIR ASSISTED.

Your air auxiliary equipment should be pre-installed and properly wired. Just

check if it is properly configured and connected as shown in the image. If any

pipes or wiring need to be reconnected, turn off all power to the machine

- 34 -

(including pressing the emergency stop) before adjusting any equipment.

8.SECURITY.

For your own safety and the safety of passers-by, this engraving machine can be

locked with the key provided. It is recommended that you use it to lock your

computer between sessions to prevent any unauthorized actions on your

computer.

OPERATION

1.OPERATION OVERVIEW.

Operate this laser engraver only by following all the instructions provided in this

- 35 -

manual. Failure to follow the appropriate guidelines detailed herein may result in

property damage and personal injury.

This section will describe only some of the options and features offered by the

operating software. Before you start using the machine, make sure you have read

the entire manual (especially the safety information above), as well as any and all

warnings provided by the machine itself.

2.GENERAL OPERATING INSTRUCTIONS.

Step 1. Create the design you want to engrave. You can do this directly in the

engraving software, or you can use any

Step 2.Please connect the companion equipment and tools to the product and

connect the power supply. You can refer to the video on CD/USB. Fill the water

inlet with purified or distilled water for the built-in water circulation. The

water level must be added to the green water level safety line. Note: (The

water level should not be too full, so as not to overflow).

Step 3. Please remove the smoke pipe. One end of the smoke pipe is connected

to the smoke exhaust port of the equipment, and the other end is connected

to an outdoor or auxiliary smoke extraction device. Note: (Please use a tube

clamp to secure the connection to prevent it from falling off.)

Step 4. Pull up the emergency stop button and use the buttons on the front of

the cabinet to open the control panel of the engraving machine. Load the

design of your choice directly from a USB flash drive or via a computer's

connection to the engraver.

Step 5. Open the engraver cover, check that the air assist is working properly, and

adjust the table if necessary. Cellular beds are recommended for most applications.

The bed can be raised or lowered using the Z-axis control on the front of the

cabinet to accommodate a variety of materials of different thicknesses.

- 36 -

Step 6. Place the material sample on the bench. The standard position is located in

the upper left corner of the table. This can be changed by moving the location of

your design or engraver's origin using the control panel or engraving software. To

handle larger materials, you can open the front or rear through door, or both, at

the same time. When the laser is active, do not insert anything into the work

surface through a pass-through door other than the material. Pay special attention

to fumes and dust that may be released through these doors. Make sure your

ventilation system is robust enough to absorb all by-products or wear the

necessary PPE to ensure the health of users and passers-by.

Step 7. Focus the laser by placing the acrylic focusing tool on top of the material

and carefully lifting the table. The laser head should barely touch the top of the

acrylic tool without applying any pressure, ensuring that the engraving distance is

correct. (Again, never try to be on the bench without material.)In any way, the

laser is focused. Close the lid.

Step 8. Customize the contrast and engraving depth of your design by adjusting

parameters in the engraving software or directly from the control panel. If your

engraving instructions detail the power setting in milliamps, use the following

conversion chart to find the appropriate power setting:

The minimum threshold is 10%. The laser will not be emitted at any setting lower

than this setting. It is not recommended to use the laser tube at full load, especially

for long periods of time. The recommended maximum power is set at 70%, as

- 37 -

prolonged use of more than this amount will shorten the lifetime of the laser. To

increase the engraving depth, increase the energy per unit area by increasing the

laser's power or number of rings or slowing down the speed parameter. However,

engraving too deep can degrade the image quality, especially for the coating

material.

When working with new materials, keep in mind that you should always start at the

low end of your possible settings. If the effect is not strong enough, it can always be

more than once Rerun the design loop, or rerun it with more powerful settings until

you create the desired effect.

The resolution should generally be set to 500 dots per inch. In some cases, lowering

the image resolution may help, reducing burn and Increase the energy of the pulses

and thus improve the quality of the images produced in certain materials, such as

certain plastics.

Step 9. Open the laser tube by inserting and turning the laser key. To reduce the

risk of electric shock, try touching the engraver with only one hand at a time once

the laser tube is opened.

Step 10. Press run to pause to engrave your design. Similarly, even if you are

wearing protective glasses, do not stare at the active laser continuously. However,

be aware of possible issues such as sparks or fires, and be prepared to ex-tinguish

fires quickly if necessary.

Step 11. Once the laser stops, check the quality of the first run and adjust the laser

parameters in the control panel or software as needed to produce the desired

effect. During repeated engraving and cutting, check the pump's tank regularly to

keep the water temperature below 100° F (38° C). If this temperature is reached,

stop working and allow the engraver to cool down before further use.

Step 12. When you are done engraving, close the engraving software and turn off

the machine in the following order: laser power, control panel, any ventilation,

water cooling system, and emergency power button. Remove the laser key from

- 38 -

the control panel.

Step 13. Clean the bench completely, emptying the lower bracket of any debris.

3.SPECIFIC MATERIAL DESCRIPTIONS.

The following instructions are recommendations that can help expedite safe work

with a variety of materials. Users should research the safety and engraving

requirements for their specific materials to avoid the risk of potential problems such

as fire, hazardous dust, corrosive and toxic fumes. Once you know that the product is

safe or with the proper protective equipment in place, it can be helpful to engrave a

test matrix of small boxes produced at various speeds and power settings to discover

the ideal settings for your design. Or start with low power consumption and fast

setup, re-run the design as many times as needed, using progressively increasing

laser intensity.

CERAMICS.

When engraving on ceramics, medium to high power is generally used. Using more

circuits instead of higher power and lower speed can help avoid material breakage

during the working process. Be aware of the health risks posed by dust from ceramic

engraving, especially for repetitive industrial applications. Depending on the material

and workload, a fan or even a complete ventilation system may be required to

resolve the issue. Similarly, operators and others in the work area may need to use

respiratory PPE, such as masks and respirators.

STONE.

When carving all kinds of stones, medium power and medium to fast speeds are

generally used. As with ceramics and glass, be aware of the dust generated

(especially for repetitive industrial applications) and take similar measures to

ensure the safety of users and others in the work area.

TEXTILES.

When it comes to carving textiles such as cloth and wool, low power and high speed

are often used. As with leather, special attention should be paid to the possibility of

- 39 -

fire and dust.

GLASS.

When engraving glass, high power and low speed are generally used. As with ceramic,

it would be helpful to run more cycles on a lower setting to avoid cracks. Care must

be taken when engraving glass and carbon fibers to avoid combining settings that

produce laser intensity sufficient to disrupt the structural integrity of the fibers of

their components, resulting in blurred markings. Personal protective equipment

should be worn to avoid exposure of eyes, nose, mouth, and skin to dust from the

use of any kind of material, especially for repetitive industrial applications. Clothes

worn when working with fiberglass should be washed separately afterwards.

LEATHER.
