  • HOW TO COOL THE BLACKTOOTH 40W LASER TUBE

    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 DIFFICULT IS IT TO BUILD THE BLACKTOOTH LASER CUTTER?

    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.

  • CAN BOOST THE POWER OF MY BLACKTOOTH LASER?

    Upgrade your mirrors to SI coated mirrors, using a HQ ZnSe lens and even pushing up to a beam expander will all boost power. The ideal order of experimenation for lowest cost would be changing out for a higher quality lens labeled HQ ZnSE lens. Next would be SI mirrors, which will absorb less heat and reflect better, the last would be to use a beam expander which expands the beam, reducing the heat signature on the mirrors and makes a tighter focal width.

  • I HAVE ONE OF YOUR SMALLER STEPPER MOTORS RUNNING MY X AXIS BRIDGE CRANE AND IF IT IS MOVED TO FAST THE MOTOR SOUNDS LIKE SKIPPING STEPS WILL 651OZ REQUIRE A DIFFERENT POWER SUPPLY CONTROLER?

    Yes, the 651 oz/in motor requires a driver that is compatible to the motors (the motor will draw 6 amps max and the driver paired with this motor will be able to allow for a 6 amp draw). I would also recommend a 36 volt power supply for better high velocity performance.

  • AM NOT SURE HOW TO SET THE Z AXIS TURN ON/OFF LASER WHEN CREATE CODE. KNOW THAT ITS TYPICALLY Z-AXIS MOVEMENT DOES THIS - BUT YOU DONT SHOW ANYTHING HOOKED UP IN PLACE OF AXIS.

    When the z axis is going down, the laser turns on. When the z axis is going up, it turns off. The z axis directions is only a signal that is either 5v or 0v. That determines the direction. In vectric, you will need to set your machining operations with a very very small depth so the time it takes to get to its final depth is a very short time.

  • I have one of your smaller stepper motors running my X AXIS bridge crane and if it is moved to fast the stepper motor sounds like it is skipping steps will the 651oz stepper motor require a different power supply and controler?

    Yes, the 651 oz/in motor requires a driver that is compatible to the motors (the motor will draw 6 amps max and the driver paired with this motor will be able to allow for a 6 amp draw). I would also recommend a 36 volt power supply for better high velocity performance.

  • WHAT IS D.O.F OR DEPTH OF FIELD FOR THE BLACKTOOTH LASER AND LENS?

    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.

  • HOW CAN YOU ENHANCE THE BLACKTOOTH LASER CUTTER?

    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.

  • WHAT THICKNESS OF MATERIAL CAN THE BLACKTOOTH LASER CUT?

    A standard 40W CO2 laser will cut up to 1/4" thick of material, be it wood, acrylic, card stock, leather, fabric, foam, cork, etc. (Decent speed and final cut are heavily dependent on a strong air assist upgrade)

    Metals cannot be cut due to the power level and wavelength of the CO2 laser. But it can be marked with special solutions like Cermark or Thermark.
