Safety Guideline

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.

Assembly Guide

Assembly Step 01:

Connect Stepper Motor Cables for each Y axis Arm- Left (a) and Right (b) to Rear Module (Contains Mainboard, I/O Connections).
Remove the Rear Module Cover for cable management.
Align the two modules – Left (a) and Right (b) with 2 of the provided Left & Right Module Connection Screws into the screw holes and tighten them with the included 4mm hex wrench.
Repeat the steps above to assemble remaining frame modules. (X Axis Module excluded).

Assembly Step 02:

Connect the stepper motor cable and the limit switch cable of the Left Module and X-axis Module.
Per the diagram place the cables into the cable channels.
Place the X-axis Module on the Left Module and Right Module and align the X-axis Module with the positioning pin on the Left Module.
Turn the machine over and place it on the desktop before proceeding to the next step.

Assembly Step 03:

Push the sliders on both sides of the Y-axis (left module and right module) on the limit screws as illustrated to ensure that both sliders are aligned.
Insert four X-axis Connection Screw (S7) into the screw holes and tighten them with a 2.5mm hex wrench.
Remove the limit screws when all four X-axis Connection Screw (S7) are properly tightened.

FAQ

I. Unable to power on the machine.
– Ensure all outlets, switches, and power cables are plugged in and powered up properly. Try a different power source or cable if necessary.
II. Unable to connect to computers.
– 1. USB cable not connected: Please make sure the data cable is correctly plugged. On some PCs, the front USB port is not receiving enough power for the engraving machine. We recommend using the USB port at the back for a stable connection.
– 2. The driver is not correctly installed: Install the driver according to the instructions again. After the installation is done,your computer os can recognize the machine as a serial port. You can find a serial COM port in the computer’s device manager.
– 3. If both solutions above are not working, try unplugging the USB cable and power cord, turn off the machine for at least five seconds, then power it on and re-connect again.
III. Machine gives no response when controlling via the mobile phone application.
– 1. The wrong machine is connected: If you have multiple machines in the workspace, please make sure you connect to the correct machine.
– 2. Compatibility Issue: Compatibility issues may occur when updating your phone to a new system version. Please don’t hesitate to contact us with your system information if that happens. We will add support for it as soon as possible.
IV. The engraving looks blurry or shadowed.
– 1. Focus: Most commonly, the laser was not correctly focused before starting the job.
– 2. Engraving Speed: If you set the engraving speed too fast, the laser will have insufficient time to engrave your workpiece. Please adjust your engraving settings and do the engraving again.
– 3. Image Quality: If the image you imported has very light colors and fine lines, it will also affect the engraving quality.
– 4. Workpiece Position: The laser module has a fixed focal length, which means the workpiece should be placed on a flat surface and make sure it is in parallel to the machine, or poor engraving result.
V. Unexpected stops when offline engraving.
– The engraving job has not been fully transferred. Re-connect the machine and transfer the engraving job again should solve the problem.
VI. Inaccurate focus
– Read the “Focus” section in the User Manual carefully. Use the focusing tools provided with the machine to adjust the focus. If the focusing tool is missing, you can use white cardboard with 5mm thickness to adjust the focus instead. You can contact our support team for further assistance if needed.
