2.4 Fire Safety
• NEVER leave your engraver alone during use.
• Always keep a fire extinguisher, water hose, or other 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.
• If installing this board on a CNC machine or other device using thermistors and heating elements, consult
www.smoothieware.org and other sources to ensure that your system and its computer code include appropriate
safety measures to avoid excessive or uncontrolled heating, with fallbacks and automatic shutoffs in case of
errors.
3 Installation
3.1 Unpacking Your Control Board
Your control board and its microSD card should arrive protected by an antistatic bag and insulating foam. If you
find any damage during unboxing or installation, please contact us immediately. Do not continue with installation
until customer service can confirm the devices’ safety or provide safe replacement(s).
You may keep the packaging in case of future return but, if you dispose of it or any part of these devices, be sure to
do so in compliance with applicable waste disposal regulations.
3.2 Preparation
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.
It 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.
