DO YOU GUYS SELL THE POTENTIOMETER FOR YOUR LASER SYSTEM BY ITSELF

check your in-going power and make sure that you have a good neutral connection. Frequently the issue is not the power supply but the power coming into the power supply that causes the problem. There is a chance that the power is good coming in but there is a loose neutral connection and that causes it. This is the neutral connection that runs all the way back to the panel in your home.

WHY DO MY 40W LASER POWER SUPPLIES KEEP FAILING?

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 TO COOL THE BLACKTOOTH 40W 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.

Will the 40W CO2 laser etch glass?

Temperature probe monitor. Very valuable. This keeps you up to date on your coolant temperature levels.

Voltage meter. This will tell you the exact level of voltage/power you are running telling the laser to run at instead of an arbitrary mark on a drawn wheel around your POT.

Ammeter sensitive to 1mA. This will be sure your not over driving your tube and reducing it's life significantly.

Hour meter. This will tell you exactly how long your system has been 'on' giving you a more accurate bead on the length of your tubes life.

Exhaust fan upgrade. The current fan included is 100CFM. You can buy 120mm fans that push 250CFM and I have included a guide on how to go about doing this here. http://buildyourtools.com/phpBB3/viewto ... 8cdd1802bf

To push the exhaust fan even further, if you have the room/power, I would highly recommend investing in a 600+ CFM "Dust Collector" system. 250CFM is still not suffice to draw all the smoke that can come off of 3mm or 1/8 MDF cutting job.

A cutting surface. I bought myself a aluminum 'egg crate' mesh from my local HVAC company. They are used a cover for fluorescent lights and work great for low impact cutting surface. They come in 4'x8' sheets and are easily cut to fit. The other side is if you can find a steel honeycomb cutting bed to fit. These can be quite costly or fairly affordable depending where you are looking. The benefit of a steel honeycomb is you can use high power magnets to hold material down.

Most of our products have a warranty that extends for 1 year; however, there are parts like end mills and laser tubes which are considered consumables. These parts, when used, become worn, or the usable life is decreased. Laser tubes are parts that, when used, shorten its life, and especially when proper methods are not used (i.e. running the tube with water), can drastically reduce the life of the tube. Therefore, the warranty for laser tubes are 30 days if the laser tube was not used.

The motor that is attached to the 4th axis is wired as follows:

The motor should have red, green yellow and blue wires coming form the motor. The red and green are paired as one coil and the yellow and blue is paired as the other coil. You can wire the motor to a 3.0 amp driver with red to A+, green to A-, Yellow to B+ and Blue to B-
