A Co2 DIY laser

Upgrade your existing engraving frame with an Endurance Co2 upgrade kit.

Compatible with: Eleksmaker, Ortur, CNCC Laseraxe, WainLux, Neje, SainSmart (Genmitsu), Acan and other GRBL compatible frames.

To upgrade any 3D printer / CNC frame / engraving machine with a Co2 tube you need to follow a few simple procedures.

1. You need to get all Co2 components ready.
2. You need to setup a tube (fix it tightly).
3. Add mirrors.
4. Install the focusing lens into the nozzle.
5. Connect all electronics to the GRBL board and a power supply.
6. Align mirrors to make sure that the laser beam goes through the focusing lens.
7. Add an air compressor.

What Endurance lasers provide:

1. Mounts and brackets for:
   1. Mirrors
   2. Co2 Tube
   3. A focusing lens with an air nozzle
2. Mirrors, focusing lens
3. Water TEC cooling system
4. Machine full enclosure
5. Electronics box.
   1. Including high-voltage power supply
   2. Converter for GRBL board
   3. Short pulses board for the alignment process
6. A detailed guide and full tech support about installation and wiring

All parts that you need

Upgrade your frame with 40 watt Co2 tube. Convert your frame into Co2 laser cutter/engraver.

What do we need to make the first launch of the machine:

1. Co2 tube
2. High voltage power supply
3. Water pump
4. Water tubes
5. mA ammeter
6. Switch
7. Potentiometer
8. Mirrors
9. Focusing lens
10. Co2 nozzle
11. Thermometer
12. Some wires and aluminum sheets.

What we ship in the package.

1. High voltage power supply for a Co2 tube
2. Water TEC cooler (Peltier) for Co2 tube
3. Silicone water tubes.
4. Mirrors + focusing lens with an air nozzle.
5. Holders for mirrors + mounts.
6. Dynamic PWM box.
7. Co2 tube holder + mounts
8. Aluminum frame (for protective enclosure)

The basic kit is 895$  + shipping costs

What else do you need:

1. 40 watt Co2 tube [necessary].
2. Air compressor (0.05-0.1MPA with 70-200 L / min capacity) [optional].
3. Acrylic / plexiglass plates to cover the frame [necessary].
4. Fume extractor [optional].

That is it to get started.

Co2 tube – make sure it has no damages. Glass is very fragile and has to make sure it is in a good condition

A high voltage power supply is needed to blast the Co2 tube. Make sure that you need a high-voltage power supply especially for the Co2 tube wattage you have.

Water pump – you may use a car washer pump to get started.

Water tubes – since the water will be under high pressure you need to make sure that is can be connected tightly and we recommend using silicone wires.

mA ammeter is needed to be able to setup proper current. Keep in mind that since you have a very high voltage then the current is setup in mA, which is 1^-3

Switch – is needed to be able to turn on/off the laser, sometimes you can have a more complex system

Potentiometer – is needed to be able to set up needed current, usually, a potentiometer should be in kOhm.

Once you setup all systems you would need to deliver the laser power and focus it at the end, therefore, you need some special Co2 mirrors and well as a focusing lens.

Schematic parameters:

Power parameters:
Current: 15 – 20 mA
Voltage: 21-25 kV

Measurements:
Water temperature < 30C
