Advantages and what you need to build your laser
- Compatible with the most 3D printers and CNC mills.
- Can be assembled within 2-8 hours.
- The guaranteed duration of the non-stop operation is 48-72 hours.
- Has a TTL for the PWM output.
- Additional useful accessories available Endurance.
- All Endurance lasers cut wood, plywood, plastic, felt, fabric, acrylic, leather.
- High quality and reliable components.
- All Endurance lasers can engrave on leather, acrylic, plastic, plywood, wood.

Lasers support 9 – 16 volts range. To operate 24 volts requires step down “buck” converter (available when you place an order).
To make your own diode laser you have to be good at:
- Electronics and soldering.
To make your own laser you will need:
- A soldering iron.
- A screwdriver and a plies.
- A multimeter: a voltmeter + an ammeter.
|What do you need?||2.1 / 3.5 / 5.6 / 8 / 8.5 watt||10 watt|
|Required soldering skills||Advanced||Intermediate|

Everything you need we will put in the parcel.
Keep in mind that to assemble a 2.1 watt, 3.5 watt, 5.6 watt, 8 & 8.5 watt laser module you need to be an advanced user in wiring, soldering.
What goes in the package for a 10 watt laser kit:
|1||Special DC/DC converter (step-down)||1|
|2||Laser module housing||1|
|3||Endurance MO1 PCB components (Power Transistor IRFZ44N, Set of 4 resistors for Endurance MO1 PCB, PC817 Optocoupler||1|

To assemble a 10 watt laser module you need to be an intermediate user of soldering iron and electronics. However, to build your own 10 watt laser it is much easier than to build other lasers.
In addition you may get an additional accessories while placing an order, including:
Those accessories are very useful.
- always wear red or green goggles when you operate the laser. Remember Endurance lasers are class 4 items and you must never aim them at any living being.
- A G2 lens
- a short focal lens with a focal range of 2-10 mm (1/10 – 2/5’’) is a necessary accessory for metal laser cutting and engraving.
- An Endurance MO1 PCB
- an electronic board to feed the laser from an external power supply (needed when your main board power output is not enough.)
- Laser connectors
- a variety of different wires and connectors to connect the laser to your board.
- Laser mounts
- aluminum mounts to hook the laser to you machine. 4 types with M3 screws: L, П, I, T
- A laser actuator
- a Z axis actuator to change the laser position on the Z axis. A good option for XY plotters with no Z-axis mechanism.
- AC/DC 12V 5A
- an additional power supply for Endurance lasers.
- AC/DC 12V 1A
- an additional power supply for 10 watt laser fans.
- A step down DC/DC converter
- a DC/DC converter to decrease the voltage down to the required 12V for Endurance lasers.
- An endurance laser box
- a nice gadget (add-on) for your laser module to measure the incoming voltage, outgoing coming voltage and current on the laser diode, laser driver module, Endurance MO1 PCB, temperature sensor and Arduino board for changing the laser power.
- An Arduino board with an Endurance sketch
- to change the laser power (duty ratio) and the frequency of the laser. Can put the laser into the impulsive mode.
- A temperature sensor
- an additional temperature sensor to monitor the laser temperature.
- additional voltmeter for measuring incoming voltage.
- A voltmeter & an ammeter
- an additional voltmeter & ammeter to measure the outgoing voltage and current that goes to the laser diode.
- An air pump
- a laser addition to blow on the work piece of laser cutting / laser engraving. Increases the laser cutting speed up to 50% and reduces charring.
- A TEC module
- A Peltier cooling system for better laser cooling (increases the power up to 10%).

Be careful when you set up the voltage and current consumption for your laser diode.
Do not use unauthorized power supplies for that. If you want to test a laser diode follow this video guidance.
Recomended parameters Voltage: 4.5-4.7V | Current: 3.8-4.2A
Overvoltage will damage your laser diode. Never set up the voltage over 5.5V
10 watt laser is the easiest unit to build.
Always wear protective goggles when you work with a laser
