Safety Information

Disclaimer
Your control board may differ somewhat from those shown in this manual due to options, updates, etc. Please contact us if your device came with an outdated manual or if you have any other questions.

General Safety Instructions
Use this device only in accordance with this instruction manual, the manuals for your laser engraver and its engraving software, and all applicable local and national laws and regulations. Only allow this device to be installed, operated, maintained, repaired, etc. by others who are familiar with these manuals and have read and understood all their warnings and safety information. Ensure that this manual is also included with your engraver if it is ever given or sold to a third party

• DO NOT install this control board if it arrives or becomes damaged. Contact customer service for help with repair or replacement.

• DO NOT leave this device separate from your engraver or loosely housed within it. Make all connections securely and then firmly secure the device to your
  engraver’s casing.

• After any adjustment of this device’s electrical connections with your engraver and its accessories, carefully test that the connections have been made correctly and the engraver and accessories are responding properly to your commands. Be especially careful of any connections to the water cooling system, heat sensors, and other safety equipment. If your engraver did not come with an interlock sensor that automatically cuts power to the laser when the work bay’s protective cover is opened, it is highly recommended that you get and install one.

Electrical Safety Instructions

• ONLY use this device with a compatible and stable power supply with less than 5%fluctuation in its voltage. If your engraver’s power supply is unable to maintain such consistency, replace the power supply before further use.
• Adjustment, maintenance, and repair of this device and other electrical components of your engraver must be done ONLY by trained and skilled professionals to avoid fires and other malfunctions, including potential radiation exposure from damage to the laser components. Because specialized techniques are required for testing the electrical components of your engraver, it is recommended such testing only be done by the manufacturer, the seller, or a specialized repair service.

Unless otherwise specified, ONLY undertake adjustment, maintenance, and repair of this device and its electrical connections when it, your engraver, and any connected accessories are turned off and disconnected from their power supplies.

• ALWAYS check that the electrical polarities are correct at every stage of installation. Reversing the polarity of power inputs can damage or destroy your board and other components. Use of a multimeter to ensure correct installation is recommended, especially for use with custom projects. Also ensure that new connections are properly grounded.
• DO NOT allow anything metallic to come into contact with this device while it is powered. Allowing a metal tool or fastener to fall against the board during use can cause short circuits, damaging or destroying the board.

Fire Safety

• NEVER leave your engraver alone during use.
• Always keep a fire extinguisher, water hose, or another flame retardant system nearby in case of accidents. Ensure the local fire department’s phone number is clearly displayed nearby. In the case of a fire, cut electrical power before dousing the flame. Familiarize yourself with the correct range of your extinguisher before use, as its high pressure can produce blowback.

Installation

Step 1: Unpacking Your Control Board
Your control board should arrive protected by an antistatic bag and insulating foam. If you find any damage during unboxing or installation, please contact customer service immediately. Do not continue with the installation until customer service can confirm the devices’ safety or provide safe replacement(s).

Step 2: Preparation
Before installation, ensure that the device is turned off and disconnected from its power supply. Read and understand the instruction manual for your laser engraver, engraving software, and this control board.

DO NOT install this device while your engraver is connected to its power supply. Turn off your laser engraver and fully disconnect it from its power supply. Open the part of your engraver’s casing that holds its control panel. Place the cover to the side while taking care not to pull or damage its wiring. IIt is recommended that you use a few pieces of tape to join the various sets of wires connected to your engraver’s current control board. Add labels similar to those shown in the picture below. Here, “PWR” is used for the main power input, “Y” and “X” for the motor drivers, and “END” for the limit switches. Any clear phrasing is fine. If your old board already has other connections in addition to these, use its manual or the board’s markings and the diagram in §1.5 as well.
