What laser controller model number do you have?

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

Additional Information:
Thanks for the model number. I am going to fabricate the parts and put it together myself to see the issue. We made this modification to the blackTooth laser cutter to better house the new laser controller that we wanted to add to the laser, but that may have been for the AWC608. If there is an issue with my assembly, we will create a new part that will correct the issue and send it to you.

Additional Information:
Thank you for the update!

There are no instructions on how to assemble the laser control unit housing that came with my 40w blacktooth laser kit. How can I get instructions for how to assemble the control interface housing? Every configuration I try blocks the wire connection ports.

could you make available a larger size picture of the exploded view of the BlackTooth laser cutter? I would like to use for reference when building my laser cutter, but it is too small to be really useful.

Yes, the blackTooth laser can cut .05 inch plastic. Generally, it can cut non-metallic materials up to about 0.25 inches. Video of an early test of the blackTooth is available on our website at https://buildyourcnc.com/blackToothLaserCutterAndEngraver.aspx#prettyPhoto/104/. There are also several posts of the blackTooth in action at buildyourtools.com.

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.

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?

There is some variation in the outward appearance of laser power supplies due to sourcing through different vendors. However, the basic wiring requirements are the same in each case. For the unit with integrated laser controller, follow the diagram found here: https://buildyourcnc.com/blackToothLaserCutterAndEngraver.aspx#prettyPhoto/0/. The terminals on the signal side will have a 6 connection terminal block -- these are the ones labeled 5V, IN, G, P (or WP), L (or TTL-L), and H (or TTL-H). The High Power side will have 3 inputs for AC power, one high voltage lead, and one return line. Connect these as shown in the diagram as well: the return line goes on the "front" (beam exit end) terminal of the laser tube, the high voltage lead goes to the "back" terminal of the tube, the FG terminal (or G) receives the earth ground wire of the AC power cable, and the two AC terminals receive the line and neutral wires of the AC power cable (it doesn't matter in this case which wire goes to which terminal).

I ordered a Blacktooth Laser, but received no response that processing of the order has started? Will I be notified of shipping as soon as the weeks lead time is complete?

The blackTooth laser power supply will use 4 - #8 x 1" screws, and 4 - #8 nuts. As stated on step 10 here (https://buildyourcnc.com/blackToothLaserCutterAndEngraver.aspx#prettyPhoto/10/)

I am building a blacktooth. I don't see in the instructions what screws are meant to fasten the power supply to the wood. The instructions show how to wire it but I don't see where it says which screws to use. I don't want to guess and end up being short later. Thanks. .

As shown in the instructions the laser tube that was used was a different model which had the metal end, compared to our full glass tube models we currently ship with the machines.
So there is no difference besides appearance between the two tubes.
The focus lens should be placed in the laser nozzle assembly and not on the laser tube itself.

Hi, I live in Australia and am looking at purchasing the Blacktooth laser cutter and engraver. I am wondering what the cost to ship to Australia would be?

The 800 series of Porter Cable routers all have the same diameter; therefore, you can purchase the latest model of that series and you should be fine with the fit for our router mounts.

Most motherboard do contain parallel ports, but the port connector may not be at the back (in the section where external connectors will be connected). Instead, the motherboard may contain an LPT ribbon connector on the actual face of the motherboard (usually along one of the edges). You will need a ribbon connector to a DB25 female connector.

If your motherboard does not contain an LPT header on the motherboard, you can purchase a parallel printer adapter that plugs into one of the PCI slots. The price of the adapter is very inexpensive and sometimes is actually less costly than the actual ribbon connector.

The greenBull instructions are found on our website. Each machine has a page, which you can locate by clicking on "CNC Machines" from the left hand menu and choosing the particular machine you have. Scroll to the bottom of that machine page and you will find complete instructions. The page for the greenBull 5X, for example, is : https://buildyourcnc.com/Item/cnc-machine-greenBull-v4-5X

The redFly is typically sold with motors already wired to conductor cable with 4-pin connectors; these need simply to be plugged into the control box. There is no soldering required. If you have a different configuration, please contact us directly at techsupport@buildyourcnc.com with information about your specific application (and a photo, if possible) and we will be happy to provide you with further guidance.

How do I know how to hook up the red fly? What color wires do I solder on which pin of the connectors? Was there suppose to be any instructions that came with it, or the entire greenbull for that matter?

For all of our kits, it is highly recommended that the instructions are completed read. This will determine if the customer has the ability to take on a project of this complexity.

Depending on the specific blackTooth option purchased, the kits include the following (if the parts is listed in the instructions, it is included in the kit unless otherwise specified within the price option):

- Structural components: Plexiglas panels and MDO structural parts that form the overall machine.
- All of the hardware necessary to assembly the structural components and to fasten the electronics and laser components.
- The electronic components to move and power the machine including power supplies, motors, drivers, interface and computer components if that option was purchased.
- Laser components including laser tube, mirrors, lens, nozzle, air pump and mounts.
- Mechanical components including drive pulleys, bearings, rails, and timing belts.

I cant find a list or description of what the kits actually contain.. Pictures would be nice befor I spend 2 grand "The BlackTooth will be provided in kit form" is a bit limited.. Thank you

That is correct. We send the fewer ribs than could be fastened within the gantry. One reduction of a rib will provide more space for the motor at the midpoint of the gantry and at the other side of the gantry (opposite the motor) can be reduced to provide more space to work with the coupling.

I'm assembling the gantry for a 5x10 greenbull and noticed that there are 9 spaces for torsion spacers but only 7 in the kit. Should I just space them out on the right side behind the motor?

You can control our 40W laser power supply (which controls the laser tube) with an Arduino, if that is your intention. The trigger for turning the laser on and off uses a 5V level. To control intensity, you can use the Arduino PWM output. If you want the Arduino to move the machine as well (providing pulse trains to each of the stepper motor drivers) then you will need to make sure you consider the processing speed of the Arduino so you will be able to run the stepper motors at the speed you need for the laser engraving/cutting.

Our laser controller do all of these functions. Here is a link to our laser control system:

Additional Information:
Thank you! I am building a 3 axis cnc/ engraver and I think this would be a good option as well as the router head and the 3d printing head. How heavy is the tube? I may mount it directly onto one of the axis of the machine to eliminate the need to line up all three axis, similar to what you have with your xl engraver.

Additional Information:
The tube isn't that heavy, but when filled with water, it can get up to a few pounds. The key is to use the axis moving the nozzle for engraving as this requires fast back and forth motion. The cutting is generally dependent on the axes moving from vector to vector at a relatively slow motion, so this is not a problem.

I would like to build a low cost laser engraver/ cutter, can your 40w laser power supply be controlled with an arduino or is it only controlled by the controller sold here?

To verify, you are still getting the laser tube to fire, but the laser beam is weak and cannot cut or engrave any materials correct?

Have you checked your tube's tungsten post terminals to make sure they are getting good contact?
The Laser tube and laser power supply both have manufacture warranty, please email customerservice@buildyourcnc.com for further assistance.

Hello, I have a blacktooth laser cutter, the machine has 10hrs of work, suddenly in the middle of a job the laser beam lost all power, I can still se the purple plasma beam but with no power or intensity, the tube is fine, water is running through and there is no arcing to the chasis or some other part. I think it might be a faulty PS how can I test it, Do I have a warranty on it?
