Safety Instructions
Always exercise safety and caution when working with laser marking systems.
Consider the listed recommendations to minimize risk.
- You must be at least 13 years old to operate the laser engraver.
- Direct exposure to the laser beam can cause severe burns and eye damage. Ensure that you are wearing proper laser safety goggles when working in the vicinity of the laser equipment.
- When you focus the laser do so only on the lowest power setting.
- Keep a fire extinguisher nearby since use of the laser may lead to an unexpected fire.
- Never leave an operating laser unattended.
- Fumes and smoke generated during the engraving/cutting process must be extracted from the room as some can be poisonous; make sure there is a ventilated system to the outdoors.
- Make sure the cutting area under the laser is metal or non-flammable.
- Ensure that the room or area you are operating the laser in is sufficiently labeled to prevent someone from unknowingly walking into an active work area.
- Be sure to disconnect the power when cleaning, maintaining or servicing the laser equipment.
- DO NOT stare at the bright and intense light appearing during the engraving process. Doing so can cause serious eye damage.
- Never use the laser except for the purpose intended.
SainSmart does not accept any responsibility or liability for any use or misuse of the Laser.

- Air assist system: When performing laser cutting jobs, an air assist system blows air through the air nozzle, enhancing the cutting performance and reducing the burn marks. You can remove the air assist nozzle when you are doing non-cutter jobs. This laser kit only comes with an air assist nozzle, to make full use of the air assist feature, you may need to prepare an air assist pump and air tubing yourself.
- Recommended Air Tubing: inner diameter Φ4.0mm, outer diameter of Φ7.0mm
- Recommended air pump: flow rate 5-8L/min.
Precautions
-
Please read the instructions carefully before use.
-
Direct exposure to the laser beam can cause severe burns and eye damage. Ensure that you are wearing proper laser safety goggles when working in the vicinity of the laser equipment.
-
Know the compatibility of the laser module and its maximum input voltage and current so as not to damage the laser.
-
When engraving reflective materials such as mirror stainless steel it is recommended to paint the material surface black with a marker before engraving, preventing laser damage and unwanted laser exposure from the reflective laser beam.
-
After long hours of laser working, residue from smoke and dirt will accumulate on the laser lens, cleaning the lens regularly is needed. After working with oily materials such as pine boards, cleaning the lens in time is necessary.
Cleaning method: use a cotton swab dipped in alcohol to wipe the lens. -
Please use a smoke exhaust device and ensure that the room or area you are operating the laser is well-ventilated.
Laser Module Installation
STEP 1: Install the Laser Module on Jinsoku LC-60A/LE-1620
- Prepare your 4mm ID (7mm Outer Diameter) Air line tubing first. Connect one end of the tubing to the air assist nozzle and the other end to the air pump. If you don’t have an air pump or flexible tubing, you can ignore this step.
- Choose the correct laser module adapter plate according to your machines. Fix the laser module onto the adapter plate with four M3*6 screws. and then install the plate on your machines with four M3 screws.
- We recommend removing the air assist nozzle when operating non-cutting jobs. To remove the nozzle you need to unplug the air tubing first and then loosen the screw fixing the nozzle, turn the nozzle counter-clockwise to remove it.
Laser Module Installation
STEP 2: Laser Control Board and Laser Module Connection
Choose the corresponding connection cable for your models and connect it to
the machine’s controller. Please make sure that you have selected the correct
cable before connecting.
Example 1: When the cable sequence of the laser interface of the
laser control card is 12V GND PWM, choose XH2.54-3P 1.5m connection cable, as
shown in the figure below. 
Example 2: When the cable sequence of the laser interface of the laser
control card is 12V PWM GND, choose XH2.54-3P 1.5m connection cable for 3018
PRO, as shown in the figure below.
Note: After the laser cable is connected, the laser cable and the laser
module connection end must be fixed firmly to avoid the laser cable connector
loosening during the machine movement and the contact resistance between the
cable and the terminal becoming large, resulting in the laser module interface
heating damage. 
STEP
1: Install the Laser Module on Genmitsu PROVer XL 4030
Find the Adapter Plate for PROVer XL 4030 (comes stock with the machine), Fix
the laser module onto the adapter plate with four M36 screws and then install
the plate on your machines with four M510 screws.
STEP 2: Connecting to a PROVerXL 4030
Connecting the Laser Control Module to a PROVerXL 4030 using the 3-pin cable
for GND and PWM and +12v for the Laser Control Module. STEP 3: Laser Focus
- Loosen the two screws fixing the laser shield, move the shield to the angle illustrated below and then tighten the screw.
- Place the focus calibration tool between the laser module and the workpiece. You can quickly set the focal length to 40mm by dropping the laser module down to the calibration tool.
- Remove the focus calibration tool and make sure not to move the laser module in the meantime, pull the laser shield down.
Installation is now finished.
If you find that the fan or the laser is not working when the machine is
powered on, please check to ensure you use the correct cable to connect the
laser module and the machine controller. Please also check whether the
connection cable is plugged correctly.
Installing LaserGRBL
LaserGRBL is a free program which works with Grbl based routers fitted with a
Laser and Laser Engravers. It will be used here to assist with setting up the
Laser, though it is capable of both sending GCode and converting images to
G-Code for Laser Engraving It can be downloaded from
https://lasergrbl.com/download/
After installation and connecting to the router the screen should look like
this:
There are a couple of customizations to be made before proceeding.
Enable Z axis Jog
Select ‘Grbl” → ‘Settings” and click on the ‘Jog Control” Tab. Make sure the
‘Click’n Jog” box is ticked and save. 
Add Custom buttons FIX URL
Download the file CustomButtons.gz from our SainSmart WIKI at the following
URL:
https://lasergrbl.com/usage/custom-buttons/ . Right click on the text ‘Right
click here to add custom buttons’ in the Buttons pane and select ‘Import
Custom buttons’. In the Open Window select the downloaded file and click Open.
The dialog box of the Import custom button will appear.
A short dialog is displayed for each of the three additional buttons. You can now select for each individual button contained in the archive file whether it should be imported or not. Select ‘Yes’ for each button.
The LaserGRBL window should now look like this. The three added buttons are arranged from left to right and contain the following functions:
NOTE: The
laser power is set by ‘S30’ in the custom button commands but this is
dependent on the Maximum spindle speed ($30) set on the router If your maximum
spindle speed has been changed you may need to adjust the laser power by
editing the buttons to change the S100 value. When the Laser is on the power
should be set so you can see the dot the laser beam makes while wearing the
Laser Goggles, normally the S value should be 10% of the $30 setting.
Use LaserGRBL to Focus the Laser
To cut or engrave efficiently we want the laser beam to be tightly focused into the smallest possible point at the top of the stock. Although the focus point of the Laser is fixed the height of the laser above the stock needs to be set correctly. Do not forget to wear the Safety Goggles.
- Place the Laser Alignment tool on the top of the stock at the side of the Laser, not underneath.
- Use the Z-axis adjustable knob to move the laser up and down until the laser calibration tool will just slide underneath the heatsink.
- Set the zero point at this position by clicking the globe icon.
If using very thin stock place a flat material underneath it to bring the top
of the stock higher and in the range of the Laser.
If using a thick stock it is possible to slacken the bolt clamping the laser
in the motor mount and slide it upwards to give more clearance. If desired,
test the focus of the laser by placing something which will not burn off a
known thickness on top of stock underneath the laser. 
If necessary use the Z-Axis
Adjustable Knob to move the Laser up and down to achieve the smallest possible
laser dot.
Then click the Laser Fire button once more to turn the Laser Off.
