Technical information

I had my doubts at

I had my doubts at first – but now that I’ve tested it out: This laser is definitely worth the money.

It beats all the cheap Chinese diode lasers I’ve tried by far. With a little time spend dialing in the settings, I can easily cut 3mm baltic birch plywood at 200mm/min in 4 passes. That’s slow by commercial CO2 laser cutter standards, but fast compared to most other diode modules.

The laser came faster than I expected, packaged securely. The guides on here and their youtube channel made it easy to figure out how to focus the laser properly.

I got excellent customer service from George. The only problem I’ve had with it was one of the fans failing. When I emailed to let them know about it, George immediately offered to send me a new one, and when I told him I had already replaced it myself, he reimbursed me for the fan. So they definitely stand behind their products.

Best settings I’ve found so far for 1/8″/3mm plywood are 180mm/min, 80% power, 4 passes.

Grant Emsley

I’d like to say, that

I’d like to say, that the endurance support is great. We ran into some technical problems and George helped us. He mailed us up to seven times a day according to provide a result of the problem. So we’d like to thank George for the time he invested in us.

Sven Batista Steinbach

Very pleased with my Endurance

Very pleased with my Endurance 8.5 watt laser purchase…George was very helpful all the way through the process by providing answers, suggestions, and professional help in general…After mounting and setting up the laser, it performs exactly as advertised I’m looking forward to more experimenting with engraving and cutting…thank you George and Endurance Lasers for your product and support.


Great work guys!

It is always a risk when ordering products on-line and even more of a risk when you are ordering from another country. You just never really know if the place you are ordering from is just interested in taking your money and you never really know if the product you will get actually lives up to the sales pitch or if it is just going to be junk and the vendor won’t respond to your calls.

Well I can tell you, that is certainly not the case with Endurance Lasers based on the experience I had in purchasing my 8.5 watt laser. George answers any questions I had before I purchased the unit, which would not be that unusual, but when I ordered it and it arrived damaged, George really showed me his true colours. He responded immediately to my email, promised to have a replacement shipped the next day and paid for the shipping to send the unit back to him. Although he provided a tracking number for the replacement, after a few weeks it had still not arrived. To this day it is still showing in-transit. When I brought this to their attention, George stepped up again and immediately shipped me another from their US office which arrived a week later.

I now have my laser installed and could no be happier. This thing is everything they made it out to be, and more. A quick email to them if I have a question and they respond fast and with very helpful answers. This is my first laser so I’m sure a few of my questions were newbie-like, but their responses never have been.

It is so refreshing to buy from a company that really cares and demonstrates superior customer service skills like these guys do.

Great work guys! And fantastic product!


One Happy Customer.


I just want to say

I just want to say what a fantastic experience I have had in purchasing my 8,5 watt laser from Endurance, I am an Educator and work for a Film School , here in spain training students in cinematography and we intend to use the laser for two things one to assist us in making parts for films so that the students can learn and secondly my wife is a special needs teacher and I will be using the laser to make toys for the children some who are 5 and 6 and cant even talk but can play, George the CEO of Endurance has helped immensely in choosing the right laser, I must have asked over 50 questions , we have had chats and video links to discuss what i want to do and he is one of the most helpful people I know.

I cant wait for the laser to arrive so we can get to work. George´s attitude to the way he sells lasers is what made me choose Endurance, I was thinking of a chinese laser of ebay but could not get anyone to answer my questions and buying a laser from a ebay company who sells lasers and then toys and underwear is not the sort of company who i should be buying a dangerous but safe machine from, I will need aftercare and in the future will be looking for a CNC Router which Endurance sells and I know where i will be coming, thanks for all your help George, I am sure we will speak more.

About laser driver & laser control board

Laser driver is one of the most important component in the laser module. Laser driver controls the voltage and the current that goes to the laser diode itself. It is important so that the laser driver sets and keeps the voltage and the current stable. It keeps the laser diode safe.

We add Zener diode as an additional laser diode protection.

TTL wire / wires are also added to the laser driver. With TTL you may change laser power (duty ratio). For 8.5 watt+ laser we make our own custom based laser drivers.

All Endurance drivers / laser control boards are very reliable and been tested before shipment.

What is improved, comparing to 8 watt laser?

  • Schematics became more efficient and reliable.
  • More efficient cooling system (fans replaced on 7200 RPM) and better heatsink is used.
  • More smart mounts.
  • Increased voltage and a current to the laser diode (before current stabilizer): 7.2V & 5 - 5.5A.

Everything that you need to know about Endurance accessories.

always wear red or green goggles when you operate the laser. Remember Endurance lasers are class 4 item and must never be aimed in any live specie.
G2 lens
short focal lens with focal range 2-10 mm (1/10 - 2/5’’) a necessary accessory for laser cutting or laser engraving on metals.
Endurance MO1 PCB
an electronic board that allows feed the laser from external power supply (needed when your main board does not have enough power output)
Laser connectors
variety of a different wires and connectors that will be useful when you plug the laser to your board.
Laser mounts
aluminum mounts that will help you to hook the laser to you machine. 4 types with M3 screws: L, П, I, T.
Laser actuator
a Z axis actuator that will help to change laser position on Z axis. Is a good option for XY plotters with no Z-axis mechanism.
an additional power supply for Endurance lasers.
an additional power supply for 10 watt laser fans.
Step down DC/DC converter
a DC/DC converter that decreases the voltage down to required 12V for Endurance lasers.
Endurance laser box
is a nice gadget (add-on) for your laser module to measure incoming voltage, outcoming voltage and current on a laser diode, laser driver module, Endurance MO1 PCB, temperature sensor and Arduino board for changing laser power.
Arduino board with an Endurance sketch
allows changing laser power (duty ratio) and a frequency of the laser. Can change the laser into impulsive mode.
Temperature sensor
additional temperature sensor for monitoring of a laser temperature.
additional voltmeter for measuring incoming voltage.
Voltmeter & ammeter
additional voltmeter & ammeter for measuring outcoming voltage and current that goes to the laser diode.
DIY checking pin kit
a full it that will help you to check pins on your board, laser power, etc.
Air pump
laser addition that allows blowing the air to the place of laser cutting / laser engraving. Increases speed of a laser cutting up to 50% and reduce charring.
TEC module
Peltier cooling system for better laser cooling (increases power up to 10%).
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.
