  • Can you shortcut the usb controller that comes with the blacktooth laser to hardware reset it?

    The USB controller does not have a reset button installed on it.

    You have some alternate options however:
    - You can remove the USB connector and re-insert it.
    - Set the USB to use external 5v by removing the jumper near the USB connector, use a 5v wall adapter and install a switch along the 5v DC power line to turn it off then on. You can use a momentary push button switch to do this.

  • my 40w blacktooth laser kit with laser control unit only came with one controller connector, but the unit has two controller ports. Should I have two wires or do I just use controller port number one?

    What is the model number of the laser controller?

    Additional Information:
    Hey - the model number on the laser controller is
    AWC708C
    S/N:708014243

    Additional Information:
    Do you need any additional information here? I really want to get going on it this weekend!

    Additional Information:
    Sorry about that. If you are referring to the CN1 and CN2 connector, I don't believe it is needed if it didn't come with the connector. The components that we send to the customer is the same package that is sent from the manufacturer of the product. I would try connecting it to the CN1 connector of both units and test the interface (control panel).

    Additional Information:
    The manual for the AWC 708 shows the two ports CN1 and CN2 connected, but that may just be for thorough documentation if the CN2 is needed for some reason. Do you have a copy of the manual or know where to find it? If not, I will put the document link here.

  • Does the blackTooth laser cutter can acrylic plastic?

    Exhausting the blackTooth laser cutter is a very important consideration and should be taken seriously, especially if you are cutting materials that give off toxic fumes when the material is burned. You will want a 4 inch hose to connect from the blackTooth to a blower, and another 4 inch hose to connect from the blower to the outside. The blower should be sufficient to provide completely negative pressure within the laser enclosure so there will be no escape of gasses.

    The connections at the machine, at the blower and at the location the hose exhausts outside should be thoroughly checked for leaks. Use a gasket, or silicone. Once complete, try cutting a non-toxic material that will give off an odor (wood, or non-toxic plastic) and try the system and determine if the smell is present.

  • Does the blacktooth laser cutter have a 'trace' ability or 'air cut' where you can visually see the proposed cuts to be made..i.e. visible laser?

    The blackTooth does not come with a beam combiner that allows a visible laser to be combined with the CO2 laser.

  • Laser; does your new laser controller uses the stander g-code files??

    No, the laser controller does not run standard g-code. Instead it uses a version of a printer control language which provides optimal results when processing detailed images and designs. If you need or want to control your laser with g-code, however, you can do so by running it from a computer using a standard machine control software. You can even set your laser up to operate both ways. Feel free to contact us directly if you need help sorting through your options.

  • why did the laser on my blacktooth slowly lose it's power during a cut? Currently does not fire. X/Y jogs fine.

    There could have been a small, slow leak in the tube, releasing the CO2 gas. The power supply could have also suffered from an electrical issue.

  • When using the laser controller, what does "engrave beyond border limit" mean?

    LaserCAD: Engrave beyond border limit.

    This is caused by a sweeping motion that is too fast and where the acceleration is too slow. My recommended action would be to keep the acceleration the way it is and slow down the speed of the engrave sweeping motion. I typically use around 200-300 mm/sec and make sure that the axis sweep motion is the nozzle along the gantry, not the gantry itself. The gantry will have too much inertia to sweep, but the nozzle is very light and can sweep very quickly.

    Specifically, what is happening with the engrave beyond border limit is where that axis is not able to slow down fast enough to not hit the border. For instance, imagine a car going 100 mph and it needs to stop within 30 feet. This would not be possible because the deceleration is not high enough.

  • What is the dot resolution (size) of the BlackTooth laser?

    The dot resolution of the blackTooth is a combination of two specifications of the machine:

    - The steps/inch (or steps/mm) which is the resolution but not the dot size
    - The size of the actual dot, which is not specifically related to the resolution.

    The steps per or resolution can actually be a range, since the driver microstepping can be modified.

    A simple formula can be used to determine the resolution:

    step per inch = (motor steps * microstepping) / (travel at one turn of the motor in inches)

    if microstepping is set at 16 (1/16 on the driver) and you are using a pulley that has a pitch of .08 inches and 20 teeth on the drive sprocket

    = (200 steps * 16 microsteps) / (20 teeth * .08 inches)
    = 3200 steps / 1.6 inches
    = 2000 steps per inch

    To increase the resolution, just increase the microsteps on the driver.

    The actual dot size will depend on the lens you are using, the material being lased, the time period that the laser energy is applied to the material, and the focal height of the lens to the work surface material. The energy from the laser will converge to a point and create a dot on the surface (which is different than the kerf of the laser cut into the material).

    The dot will appear in different sizes depending on the material because, say wood, will burn causing a dot that burns the fibers of the wood and spreads a bit. The dot lased on the surface of a plastic, say Plexiglas, the dot will be smaller because the energy is absorbed only at that point, but since Plexiglas is a thermoplastic, a bit of the energy will melt the dot edges depending on the time frame (period) that the energy is applied to the surface.

    The focus of the laser energy from the lens looks like a cone converging to a point, then diverges outward after that point. Depending on the distance from the lens to the surface of the material, the dot will be bigger or smaller. You want to find focal point (where the energy is focused into a point). You can use the technique where you lay a material on a slope and lase that material along the slope to find the sweet spot (dot) and that will be your smallest dot, or kerf location. Remember that the kerf will widen or narrow within the material thickness depending on the focal length lens specification (the cone will be shorter or longer depending on the lens focal length).

  • This is for the blackTooth Laser Engraver with integrated Laser Control Unit. The LED panel is quite a bit smaller than the cut out provided.

    Please send photos of what you are trying to fit together so we can determine if you have the correct parts. The LED panel is designed to be contained in a small housing that attaches to the front of the blackTooth.

  • WHAT ARE SOME USEFUL MODIFICATIONS CAN APPLY TO 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 solder will stick on the tungsten terminal of the laser tube in a Blacktooth kit?

    We use a standard leaded solder with flux. To help the soldering, you can add flux to the wire end and the tungsten rod. We have not tried non-leaded solder in fear that we would crack the glass with a rapid temperature rise. The leaded solder will melt at a lower temperature.
