CO₂ Laser Safety & Policies WARNING: The safety precautions below are mandatory guidelines that must be followed. LightObject will not be held responsible for damages or injuries resulting from improper use of the laser machine. DO NOT operate the laser machine until you have been properly trained. DO NOT make contact with any exposed wires on the machine.

Vinyl Fumes produced by above materials can cause irritation to eyes, skin and the respiratory tract. This material should not be exposed to elevated temperatures. Laser Safe Materials: Acrylic, Wood, Leather, Plastics (ABS, POM, Polyimide, PP, Styrene), Fabric, MDF, Cardboard, Paper, Foam, Fiberglass, rubber P.

First Time Laser Setup The following components are required for operating the laser machine: Air Assist: to blow smoke away from the beam, preventing damage to the lens and preventing burning the material. Water Chiller: to circulate cool water into the laser tube to prevent the tube from overheating. The laser tube needs to be at a cool temperature of 15C - 25C or else the laser tube may overheat and potentially crack.

Be sure to connect the silicone tubing on both sides of the laser tube. Connect water tubing between chiller and machine. Chiller’s outlet goes to machine’s inlet. Machine’s outlet goes to Chiller’s inlet. The correct direction of water flow is from high voltage side (red wire) of the laser tube to the low voltage side.

IMPORTANT: if large bubbles are present when the laser is firing, the tube can crack. Check for bubble every time the water chiller is turned on. 10) Secure the laser tube on the laser tube mounts. For laser beam alignment, paper can be placed between the tube mount and laser tube to adjust the position.

For wire type connection, make a secure twist. Then shield it with a piece of silicone tubing to prevent arcing. Make sure there is no moving parts around which could loosen the twist. Twist For pin type connection: Wrap the wire around the tube’s metal pin. Fix the connection by proper soldering OR applying silicon glue.
Installing Other Accessories Exhaust Fan Installation Some materials such as leather or wood generate larger amounts of smoke than other materials. An exhaust is necessary to remove harmful fumes and smoke. The exhaust must be ducted to the outside and away from any area where animals or humans congregate. Connect the air exhaust hose by using the hose ring clamps provided, connecting the exhaust hose is done in the rear or underneath (varies based on machine).

Air Pump / Air Compressor The Air Compressor (sold separately) are used to blow air through the laser head. This will blow away debris and smoke from the laser beam while allowing for a cleaner cut and protecting the lens. The air compressor on/off switch should be close by and preferably on the same circuit as the water chiller and exhaust fan to ensure it is in operation while running the laser machine.
Connecting Laser Machine to Computer The laser machine controller works with these software a) AutoLaser for Topwisdom, LaserCAD for Trocen, RDWorks for Ruida (for Windows only) b) LightBurn (for Mac and Windows) Example:Set up with RDworks Download and install the software RDWorks from http://www.rd-acs.com/ Connect the USB cable.

Follow the instruction from the screen, and it will guide you connecting the computer to the laser machine. If machine origin is not set correctly, the job file sent to the controller could be mirrored. Ranger uses rear right. P. 15 rev.

NOTE: Please refer LightBurn instruction manual and tutorials in their site for configuration and usage. Some controllers need to be set to USB instead of Serial/USB. If you are using LAN connection, input the same IP address set on the laser controller. NOTE: Please make sure LAN cable is connected between computer and laser machine.
Sending Files to Laser Machine Once you have established the connection between the computer and the laser machine, job files can be transferred. To do this, click on the “Send” button(LightBurn) OR “Download” button (LaserCAD) located on the right side of the laser software. Alternatively, save the file as UFile and put in a USB stick.
Control Panel Keypad Note: Since the laser cutter can be connected to different controllers (e.g. Ruida RDC644XG), please always refer to the controller manuals for details. Functions of typical keypad: Reset: Reset the gantry; Origin: Set the relative origin; Laser: Fire the Laser temporary; Box/Frame: To track by the current job working area;...
Laser Current Control It is important that the laser tube does not run with over current as it could damage the laser tube. Normally, we will limit the maximum current output by using software or laser power supply’s potentiometer before it is shipped. On some machine models, there is a Manual/Auto switch.
Disable rotary under 7813 menu, then reset. Z-table Usage Ranger3 has dual motors sharing one driver for z axis. Do not put anything heavy on the work bed when machine power is off, otherwise the bed can move down by itself.
Focusing/replacing the Lens The lens should be adjusted and focused according to the thickness and type of material. The distance between the lens and the work piece should be kept equal to the focal length. When using the default 15by50.8mm lens, the gap between the nozzle and material should be kept at about 6mm.
Maintenance Cooling: Automotive antifreeze should not be used as a laser coolant. Distilled water shall be used. The coolant should always be clean and clear. Focal lens: This is the lens that is used to focus the laser beam. This lens should be cleaned before it gets dirty.
Once the first mirror is done, repeat the steps to align the 2nd mirror. When mirrors are aligned correctly, the mark will be in the center regardless of the x and y position (wherever the laser head moves). Troubleshooting The machine does not turn on: Make sure to check below 1.
