The laser does not work
Please, check the power adapter’s (voltage & current) performance. Connect the TTL wire to the 12V+ to test if the laser is working. It should work full power. Watch this video.
The laser works full power but the laser power cannot be changed
Please check the g-code parameters (S / L) used for the pin to change the power. Either your PWM does not change the duty ratio or the contact of any of the laser connectors (if you run without TTL) is broken. Check with the voltmeter and ammeter if the voltage on this pin changes. Watch a video about TTL signal. Arduino with TTL.
I did everything as described but the laser does not work
We need to see a detailed photo and video of what you have done to help you with further steps.
Sometimes 13N10 or LM338 die and need to be replaced. We will guide you how to do that.
Endurance MO1 PCB does not work
The Endurance MO1 PCB is a quite a simple circuit and works pretty stable, however, there is a simple way to check it out. (described on this page + video guidance)
How do I find a proper pin to connect the laser?
We provide an ultimate guidance and tutorials. The laser is usually connected to the fan output on 3D printers or spindle output on CNC machines or can be connected to any other pin that is controllable, such as: D11 on the Arduino Nano. Detailed pinouts you may find here.
The laser lost its power.
The probability that this might happen is 5%. It might happen due to overheating. Avoid the laser diode and laser control board overheating. Check the temperature of the heatsink or laser driver. They must not be VERY hot (if you can touch these elements and hold on – it means that the temperature is less than 70C). If the temperature rises too high we can guide you how to reduce the voltage going to the laser diode and causing the loss of power.
I am trying to cut 3-5mm plywood using the laser, however I still did not manage to cut it with a single pass. Please assist
  1. use a G-2 lens for laser cutting.
  2. setup a perfect focus on a G-2 lens (make sure that focal range is something like 4-8 mm)
  3. make sure that a plywood is very dry (you may use a 3D printer bed to warm it up)
  4. speed parameters should be 50-150 in your g-code
  5. make sure that the plywood is not specially treated with anti-inflammable materials
  6. make sure that the laser runs full power and you have enough power that goes to the laser
  7. make sure that the lens is clean and has no dust on it.

You may cut and engrave using this diode laser

Differences between Endurance lasers

2.1 -> 3.5 watt -> 5.6. watt – 8 -> 8.5 watt. More power & more cutting and engraving abilities
10 watt “Invincible” -> 10 watt Delux : has an air nozzle, bigger focusing ring, laser box instead of a laser control board.
10 watt Delux -> 10 watt Plus : has a TEC cooling with an external heatsink, air compressor.

8.5 watt -> 8.5 watt PRO : has a metal laser box ver 2.0 with MO2 and a smaller heatsink. (Additional accessories in the package)
10 watt “Invincible” -> 10 watt PRO: has a metal laser box ver 2.0 with MO2 and polished shining aluminum housing. (Additional accessories in the package)
10 watt Plus -> 10 watt PRO PLUS : has a metal laser box ver 2.0 with MO2, a ver 2.0 air nozzle, double TEC cooling with a turbine fan. (Additional accessories in the package)

Endurance makes and delivers solid-state (DPSS) lasers with different power output

and diode lasers starting from 2 watt (200 mw) up to 30 watt (30000 mw).


Endurance lasers have class 4 and you must comply with safety rules: always wear goggles and never ever aim at any living being.

Endurance lasers are reliable, have rated power output, and can work continuously for 48-72 hours.

All lasers are assembled and tested individually.


Endurance lasers are complicated high-tech devices compatible with any 3D printer / CNC machine / XY plotter. The Endurance laser key function is the ability to engrave / cut / etch / weld a variety of materials.


The technological structure of the Endurance lasers

The heart of the Endurance lasers (10 watt models) is NICHIA 445nm powerful diodes in TO5  housing.
The diodes are securely fixed (collimated) in copper or aluminum housings.

Either 3 elements (long focal) or G-2 (short focal) lenses can be added to the housings by way of screwing on.
All Endurance lenses have labels marking the best focus achieved.


Endurance makes its own heatsinks with aluminum housings.

To spread up the generated heat we use a high-quality thermal conductive paste.

The laser diode requires stabilized current and very accurate voltage settings.
Endurance makes its own laser controller board with a Zener diode at the end of the board.

The laser controller board has a TTL (PWM) that works from 3.5V-24V range wire and a DC/DC converter that allows a laser unit to operate in the range of 9-16V. All Endurance PRO versions have analog input 0-10V.
The TTL allows changing the power (intensity) during the process of laser cutting/laser engraving.

We have developed an Endurance MO1 PCB and Mo2 PCB enabling to use of an external power supply to feed the laser when the mainboard does not have enough power. In this case, just add an Endurance MO1 PCB and get an external power source for the laser.

Key Technological Advantages of Endurance Lasers

  • An effective current stabilizing schematics preventing the diode from over-clocking.
  • A highly effective air cooling system keeps the diode cold.
  • A compatible mounting system allows hooking the laser to any chassis.
  • A tuned and labeled lens to adjust the laser focus.
  • An advanced Endurance MO1 PCB allows feeding the laser from an external power supply.
  • An additional TTL wire enables to adjustment the power of the laser.
  • The lightweight of the laser module reduces the momentum of inertia.

All Endurance lasers have similar parameters but different power output

Key features for Endurance lasers are:

Operating Voltage: 9-16V (sted – down “buck” DC/DC converters available upon request)
Operating Current: 2 – 14A
Cooling: active airflow (some units equipped with TEC cooling)
Mount: compatible with most 3D printers and CNC mills
Weight: 100-700 grams (~ 1/4 – 1.5 pounds)
Wavelength: 445 nm+-2nm (blue)
TTL: yes
Total lifetime: 10 000 hours.
Continuous operation time: 48-72 hours.
Focal range with 3 element lens: 2-10 cm (1-4”).
Focal range with G2 lens: 5-30 mm (0.2-1.25”)

Endurance laser production

Endurance has several steps while laser production:

  1. We purchase and test all components before starting an assembling process.
  2. We do metalwork: cut aluminum drill necessary holes in an aluminum housing, drill holes in a heatsink.
  3. We make our own laser driver.
  4. We make assembling: laser driver is inserted into a metal housing, laser diode inserted into a heatsink is mounted to the housing, screw fans.
  5. Final tests: we do 2-3 hours test of a final unit (measure temperature, measure power consumption, laser beam quality, power stability).


The difference between Chinese analogs

Unlike Endurance most Chinese diode lasers analogs with output 2 (2000 mw), 3 (3000 mw), 5 (5000 mw), 5.5 (5500 mw), 8 (8000 mw), 10 (10000 mw), 12 (12000 mw), 15 (15000 mw) watt output are not rated properly and in fact, do not have that power output.

Another issue is that most Chinese lasers do not work continuously and can operate only 5-15 minutes maximum and then require idle time.

Unlike Endurance, most Chinese companies do not provide customer support about how to connect, how to mount, etc.
