Endurance lasers getting started page.

All you need to know about how to connect the Endurance lasers to your 3D printer or a CNC router.

When you get the Endurance lasers or you are about to place an order – on this page we explain and guide you about what you need to know before getting started with Endurance lasers.

Safety first

laser protective goggles

All Endurance lasers are class 4 means that you should never operate the laser without special protective goggles.

We always send red, dark red, green or dark green goggles. They will protect your eyesight from the reflective laser.

You should never shine with the laser at anyone or try to see inside the working laser (even with protective goggles)


About Endurance laser boxes

All Endurance diode lasers are equipped with 3 types of laser boxes. Those laser boxes feed the laser with a stable power (current and voltage) and allow you to operate the laser, turning on/off and modulate the power.

There is a detailed PDF guide showing the purpose of each wire, sensor, and switch.

Wiring Endurance lasers

Usually, our lasers are very easy to wire.

Laser boxes ver 1.0 and 1.1 have PWM pins and can be connected to PWM pins on your laser board or FAN1 pin on 3D printers. PWM frequency should be in range 250-500 Hz and the voltage on that pin can be in range 3.5V-24V.

Laser box ver 2.0 has a more advanced PWM with no frequency limit and has an analog input 0-10V that allows operating the laser on all types of CNC machines.

However, some CNC machines require an extra (add-on)  to connect the laser box to its board, for example, Shark CNC requires laser box ver 2.0 + a special add-on (we provide them for free upon request).

Keep in mind that if you have 3 pin output, for example, PWM, GND, 12V, you do not need to use 12V, just PWM+ground.

If you are not confident that your 3D printer or a CNC machine has a PWM or an analog input – send us your machine wiring diagram to and we will check it out for you.

Laser mount.

It is very important to properly hook the laser on your frame. Most users hook the laser near the extruder (however sometimes it is better to remove an extruder to reduce the weight of the moving part) and near a spindle on CNC frame.

Our customers make and share their laser installation

Installing Endurance lasers on difference CNC frames


If you need to extend laser power cords you can do that with AVG 10 or AVG12 wires.

If you need to extend laser PWM wires you can do that using AVG22 or AVG24 wires.

All you need to know about wires (AWG).


For hooking the laser we offer a wider variety of different mounting brackets.

Some brackets we offer are made of aluminum.

Universal laser mounting brackets


We tried to make Endurance lasers mounts as universal as possible so that any of you can easily mount the laser.

Keep in mind that the better the laser is hooked the better engraving and better cutting quality you will get.
We suggest using mounts like this: П /  L /  I / T shapes. Check our STLs files on Thingiverse >>>

If you need a mounting pack you are welcome to order on our online store >>>

All mounts

Some of our mounting brackets are made out of PLA plastics and can be 3D printed and can be easily modified.

Laser beam focusing

Once you wire and hook the laser you need to set your focus.

We send lasers with pre-setup focus (you may find it on a business card). The focal range from the laser to a surface is about 65-75 mm (~3”) and can be changed.

Different lenses have different focal ranges.

Air nozzles

If you plan to do a lot of laser cutting we suggest using an air nozzle for an effective laser cutting.

Laser power supply

Usually, we send all necessary power supplies for the laser you bought with your local plug. However, you may use yours as well. All Endurance lasers work from 12 volts but require different current.

In case you have a 24V power supply – we suggest using a step-down “buck” DC/DC converter.

The power requirements can be found on a product page. Usually, it is 12V 4A minimum for 10 watt “Invincible” and 12V 15A for 15 watt “Duos” and 12V 30A  for the DPSS laser module.

10 watt PLUS and 10 watt PLUS Pro require power for TEC cooling system (it is an independent power supply that goes to it).


Please check with your power adapter and power output. Your power brick should have at least +1-2A more from their max output. If you run your power adapter and your control board on a maximum output it can cause damage and overheat. Be careful with that!

Getting started with Endurance lasers

Your power adapters should always stay cold.


Where is positive and negative in the laser jack?

We use standard positive polarity on our lasers like this


Endurance troubleshooting

In case you face a problem with the laser, for example, something is not working or it works not like how you expected, you are welcome to follow this troubleshooting guide.
