If you are unable to install the parallel port driver during the Mach3 installation process, it is most likely that you are running a 64-Bit version of Windows. Install a 32-Bit version, and retry the Mach3 installation.

HOW MUCH MDF IS USED FOR THE BOOK MACHINE COMBO #1

I'll be honest, it can be pretty awful at times. You'll want a dedicated exhaust line. Cut a new hole, make a dedicated line. Also, invest in a charcoal air filter, it will help. Trust me. They can also be done DIY very inexpensively. Buy a "Universal Pre-filter" and simply wrap it around a screen and have air push down through the screen wrapped in the charcoal laden felt. $20 + fan + screen. Away you go =)

HOW BAD IS THE SMOKE AND EXHAUST USING BLACKTOOTH?

The blackTooth Laser cutter and Engraver can be built in a weekend. Take a look at the build instructions and try to determine if you feel you have sufficient capability to put together the laser system.

HOW DIFFICULT IS IT TO BUILD THE BLACKTOOTH

The parallel breakout board has a relay that can turn the router on and off according to the control software in the computer. The router will turn on automatically prior to the machine moving (a time frame can be set so the router is up to speed). When the machine is finished and is not moving, the router automatically turns off. This is with the m3, m4, and m5 codes in the g-code.

If you are interested in the USB breakout board, you will need to get an independent relay board.

HOW TO KNOW IF THE POWER SUPPLY OF THE LASER TUBE IS DAMAGED

In Mach3, go to the Settings Tab, and select "Set Steps Per Unit". It will ask you how far to move the machine. Before you do this, make a mark on the table exactly where the end mill is resting. You can do this by lowering the end mill until it touches the material, then spinning it by hand to cut a small dimple in the material. Then, raise the end mill to clear the material, and assign a distance to move the machine. Once the machine moves and stops, measure the exact distance that it actually traveled with a tape measure, and enter this value into the dialog box that asks how far it moved. Mach3 will automatically adjust your steps per unit for that axis to be more accurate. Do this for all axes often to ensure you are cutting accurately. The longer distances you use calibrate, and the more precise you are with your measurements, the better.

These machines are inherently dangerous. Before the machine moves, the machine should be clear of any person by a dimension of at the distance of a persons reach plus a few more feet. This is the policies we institute in our shop and what is recommend to all of our customers. Treat these machines as you would treat any major power tool in the shop.

With that said, you can certainly add some protective parts, but still keep folks away even with those installed. I would use the gantry side to do all of the mounting of the protective parts. Consider using sheet metal that you can bend and make a simple installation right on the gantry side.

HOW LONG SHOULD THE MOTOR CABLES BE FOR BLACKTOE

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.

HOW TO HOOK UP THE VFD INVERTER WALL OUTLET?

Influenza is the most frequent cause of death from a vaccine-preventable disease in the United States. From 1990 through 1999, an average of approximately 36,000 influenza-associated pulmonary and circulatory deaths occurred during each influenza season. In addition to fatalities, seasonal influenza is also responsible for more than 200,000 hospitalizations per year. Rates of infection from seasonal influenza are highest among children, but the risks for complications, hospitalizations, and deaths are higher among adults ages 65 and older, children younger than 5 years, and people of any age who have medical conditions that place them at increased risk for complications from influenza.

A novel H1N1 virus was first detected in March of 2009 and quickly spread to pandemic levels. In the U.S., it is estimated that approximately 43-89 million persons became ill with 2009 pandemic H1N1 from April 2009 to April 2010. The virus also resulted in significant hospitalizations and deaths among children, adults 19-65 years, obese persons, and pregnant and post-partum women.
