PLH3D-CNC Adapter (center), PLH3D-6W-XF (bottom left), optional cables with CNC machine
connector (bottom right), external keylock (top right) and stop button (top left).
The PLH3D-CNC Adapter serves as a versatile interface and safety unit connected between a
CNC machine and a high-performance PLH3D laser head.
Many types of CNC machines and 3D printers available on market, with different control
voltage standards and levels available, may be used to control the PLH3D head. The PLH3D-CNC
Adapter converts all these signals to the standard compatible with the PLH3D head.

The laser head can be made operational by selecting to armand disarmthe laser head.
Arming means turning the head power supply on; the armed head is then able to generate a laser
beam. Disarming (turning the head power supply off) brings the laser head to a safe state where
generating a laser beam is altogether impossible.
Built-in safety mechanisms prevent misuse and unexpected behavior in case of an
emergency. The key switch protects the laser head from being armed by children and other
unauthorized people. Arming the laser head is always done manually by the user, by pressing a
button. Special circuitry prevents arming during an internal electrical malfunction. The laser head is
automatically disarmed in case of an emergency such as a loss of the mains supply (grid power), PSU
failure, breakage, or disconnection of the laser head cable. After disarming, the system remains in a
safe state, and rearming always requires the user to press the button.
Additional safety mechanisms can be incorporated into the system by adding up to two
external switches (e.g., a limit switch, a key switch, or an e-stop). There is also an additional
extension connector for future purposes
Additional feature are industry-standard screw connectors. A dedicated, low-noise desktop
power supply unit assures compatibility and reliability as well as eliminates problems caused by
using third-party power supplies. The general status (power on, arming, laser working) may be
inspected at a glance by looking at the three LEDs.

The detailed description of the distinct sections of the Adapter:
1. LASER HEAD CONNECTOR
1.1.Attach the laser head cable here.
2. EXTERNAL SWITCH CONNECTOR
2.1.Up to two external switches (e.g., a limit switch, a key switch, or an e-stop) that
arm/disarm the laser head can be connected to the PLH3D-CNC Adapter. When not using
a switch, replace it with a jumper wire.
2.2.Opening any external switch disarms the laser head immediately.
2.3.Then, even if the switch has been closed again, the system will stay disarmed. The mode
button must be pressed to rearm the laser head.
3. EXTENSIONS CONNECTOR
3.1.Intended for future applications.
4. POWER SUPPLY CONNECTOR
4.1.Plug in an external 15-24V DC power supply here. We strongly recommend using a
dedicated power supply unit exclusively for the PLH3D-CNC Adapter.
5. CONTROL CONNECTOR
5.1.Controlling inputs and outputs are attached here.
6. MODE BUTTON
6.1.Pressing the mode button once will arm the laser head. Doing so will cause the ARMED
LED indicator to light up, implying the laser head is in the armed state; the fan in the laser
head starts to work as well. To disarm the laser head, press and release the button again.
6.2.A test laser pulse can be generated in the armed state by pressing and holding the mode
button for at least 1.5 seconds. An approximately one-second-long pulse at 100% power
is then issued on the laser head control line. The LASER LED lights up, confirming the
appearance of the pulse. A single pulse will be generated even if the button is held for
longer. Please refer to "Getting Started" section.
6.3.Holding the mode button while turning the power on activates the configuration mode.
For further details, please visit the For Advanced Users section.
7. LED STATUS INDICATORS
7.1.The POWER LED shows the presence of power and also signals supply errors.
7.2.The ARMED LED shows the arming state. Furthermore, it also signals both disarming by an
external switch and disconnecting the laser head.
7.3.The LASER LED shows the presence of the laser head controlling signal (a steady one or a
pulse-like). Note that controlling the laser head is disabled in the disarmed state.
7.4.In configuration mode, the LEDs show the current option(s). Refer to the For Advanced
Users section. For adapters sold after 20-July-2020, the currently set Enable Option will be
displayed for 1 second after turning the switch key on.
7.5.For adapters sold after 20-July-2020, the currently set Enable Option will be displayed for
1 second after turning the switch key on.
8. KEY SWITCH
8.1.Turn the key switch clockwise to the upper position to switch the PLH3D-CNC Adapter on.
Turn the key switch counterclockwise to the left position to switch the PLH3D-CNC
Adapter off.

Getting Started
1. Connect the laser head to the PLH3D-CNC Adapter.
a) At this instance, the laser head ought to be mounted on your CNC machine or 3D Printer in a
firm manner.
b) If you are using the Magnetic Laser Docking Station, connect the laser head to the docking
station. Please follow it up by connecting the docking station to the PLH3D-CNC Adapter. This can
be done via the 5-wire cable, which is provided in the bundle.
c) To find out more about how to connect the cables, feel free to have a look at our video guide
available at https://youtu.be/MQ5v1CD_rlc
d) Remember to subscribe to our YouTube channel. You will immensely benefit from Opt Lasers'
hands-on tutorials and inspirations.
2. Connect the signal wire to the PLH3D-CNC Adapter, and to the CNC machine controller (a visual
representation is depicted in the "Connection to CNC Machines" section).
3. Important: Please don't forget to wear a pair of laser safety glasses that can shield you from 400
to 500 nm light radiation.
4. Place a piece of non-reflective material under the laser head, such as balsa or plywood. During
the next steps, the laser will be turned on.
5. Connect the power supply to the PLH3D-CNC Adapter.
6. Turn the switch key in the PLH3D-CNC Adapter.
Note: After turning the key switch On, the current Enable Option setti ng will be displayed with
indication LEDs for a second. (Applicable for PLH3D-CNC adapter sold after 20-July-2020)
After that Power LED should be lit. If it's not, go to the "Troubleshooting" section.

7. Press the Mode button once. The Armed and Power LEDs ought to be radiant at this point. If this
is not the case, go to the "Troubleshooting" section of the user's manual.
8. Now the laser head will be tested. Press the MOD button continuously for approximately 2
seconds. A short laser pulse (at full power), lasting for just about 1 seconds, will be generated.
This procedure will verify whether the laser head is connected in a correct fashion. If it doesn't
work, go to the "Troubleshooting" section.
9. Once the laser has been connected properly, and the procedure described above has been
concluded without any issues, you can start engraving and cutti ng using your CNC machine with
the laser head attached.

PLH3D-CNC Adapter Enable Options
Specific CNC machines issue special disable/enablesignals for turning the laser beam off and on.
The PLH3D-CNC Adapter can be set in such a way that the laser beam is enabled only for certain
states on two Enable inputs and disabled in other cases. A total of 12 distinct combinations of states
(called Enable Options) may be selected. This allows the PLH3D-CNC Adapter to connect with
virtually any machine.
