Cooling is not as tricky as you might think. There is 3 ways to approach this, only 2 really matter for a low scale 40w setup. First one is the cheapest and easiest. The higher the temp of water the worse your performance will be, from what I understand anything in the 30C range is about the most tolerable it gets. Lower is better. But not frozen...from what I've been told a very experienced cutter, he found 8C was the highest power he achieved.

1. Use a 5 Gallon resovoir system which gives you a fairly large space of water to heat up before you need to tend to it. Add about a cup of anti-freeze to the mix of DISTILLED water. You don't want ANY minerals in the water that might build up in your system. The anti-freeze works to keep algae and other ickies from growing in your water.

2. Use a smaller resovoir system (or even closed loop) and install 1 or more radiators found in CPU cooling systems with 120mm fans attached. This will continously cool your water system to ambient room temperatures, but with a tiny resovoir it will be difficult to add things like ice-packs to drop the temps if the ambient is quite hot.

3. Using an industrial coolant system. Overkill and unless your cutting A LOT, this is a very expensive option to take. You can also explore the idea of Peltier cooling but it is extremely expensive electricity/BTU wise compared to an industrial cooler.

HOW CAN COOL THE LASER TUBE?

CO2 lasers can (40w included) can mark glass, but it is not actually etching the glass. When a CO2 laser's focal lasing energy is at the surface, or just past the surface of glass, the air inside that portion of the glass will expand and cause a tiny crack. This gives the appearance of etched glass, but not with the same fineness of etching from, say, sand blasting or acid etching (with hexafluorosilicic acid). If the laser "etching" of the glass is not to the fineness that you desire, you can laser cut the adhesive material used in the acid etching process as an alternative.

You also need to consider the glass you are using. I have learned that not all glass is created equal. Some glass will work well for this (dollar store glass we have tested and works well), and some will not. I believe that lasing tempered glass will probably give some interesting results.

Depth of Field. This is how far the focal point goes before re-expanding again. With a 2" lens, you have approximately 2-3mm of DOF. This means that you'll have 2-3mm of perfectly focused laser before it starts to re-expand again. If you have a 4" lens, you will have up to 7mm of DOF.

IS THERE A WAY TO GET RID OF THE PARALLEL CABLE AND SOMEHOW USE USB ?

Yes, you can use a touch probe with our machines as it is really independent of the machine structure, mechanical components and motion electronics, for the most part. We don't currently sell touch probes, however, but standard touch probes for CNC machines will work fine.
