Detailed guidance of how to connect the Endurance lasers to your 3D printer or CNC router.

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

“How to” guidance: connecting and mounting the laser to:

Laser mount

Endurance lasers are quite universal and can be hooked to any 3D printer and CNC machine.
We suggest to use mounts like this: П L I T shapes.

If you need a mounting pack, please add them while placing an order “laser mounts”.

Mounting pack includes 4 different typical mounts that you might need to hook up the laser.

Electronics and pinouts

Intro video of connecting and running the laser with and without the Endurance MO1 PCB

Endurance has a laser driver that is inside the metal housing (in models 2.1W, 3.5W, 5.6W, 8W, 8.5W). For models 10W, 10W+, 20W the laser driver is inside the external laser box or laser control board. Please do not do anything there unless you have permission from us and you know what to do.

All Endurance lasers have TTL output. For models 2.1W, 3.5W, 5.6W, 8W, 8.5W TTL has only 1 wire (control wire) and use the same common ground as for the laser power. It is important that TTL can be controlled with 3.5-12V output (digital). Usually, it connects with PWM output on your mainboard (3D printer / CNC machine or engraving machine).

Learn more about TTL signal.

If you do not have a PWM (like most 3D printers), then just connect the TTL wire with the 12V input of the laser. It means that the laser will turn max power all the time. If you want to adjust power – then change the duration of a signal.

Laser power supply

2.1 watt, 3.5 watt, 5.6 watt, 8 and 8.5 watt Endurance lasers work from 9 – 16V range.
If you have 24V power output on your 3D printer or CNC router – let us know and we will ship you step-down “buck” DC/DC converter.

If you do not have enough power on your mainboard, then for 2.1 watt / 3.5 watt / 5.6 watt / 8 watt / 8.5 watt you will need an additional power supply. Use the Endurance MO1 PCB for that.

10 watt / 10 watt+ / 20 watt can operate from 9-24V range.
10 watt laser requires 2 power supplies: 12V 5A for the laser control board or laser box and 12V 1A for the fans.
10 watt+ laser requires 3 power supplies: 12V 5A for the laser box, 12V 5A for the TEC cooling and 12V 1A for the fans.
20 watt+ laser requires 3 power supplies: 2x 12V 5A for the laser box, 12V 1A for the fans.

Additional laser wires

We send additional laser connectors all the time to save your time while laser connecting with your main board.

If you have an Arduino board or GRBL board – it is quite easy to connect our laser.
Getting started with Endurance lasers

Endurance lasers requires different amperage (total):

2.1 watt – requires 2 amps. (external power supply is required only if you use Endurance MO1 PCB).
3.5 watt – requires 2-3 amps. (external power supply is required only if you use Endurance MO1 PCB).
5.6 watt – requires 3-4 amps. (external power supply is required only if you use Endurance MO1 PCB).
8 watt – requires 4-5 amps. (external power supply is required only if you use Endurance MO1 PCB).
8.5 watt+ – require 5-6 amps. (external power supply is required only if you use Endurance MO1 PCB).
10 watt – requires 6-7 amps. (external power supply is required for the laser + for the fans).
10 watt+ – requires 10 amps. (external power supply is required for the laser + for the fans + TEC cooling).
20 watt – requires 10-12 amps. (external power supply is required for the laser control board + for the fans).

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!

You 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

Quick jump with an Endurance MO1 board

When do you need an Endurance MO1 PCB?

You need an Endurance MO1 PCB in case your main (control board) does not have enough amperage output.

TTL white wire is connected to input 12V power (red one)

Endurance MO1 PCB allows having an external power supply to feed the laser while you keep using your existing power output to just turn on and off the laser.
We suggest to use it if you are not confident with your pin power output.

You have 3 pairs of cables:
The first pair goes to the laser.
The second pair goes to the external power supply.
Еру еhird paid (the tiniest one) goes to your existing control (main) board.
