I was wondering what the max depth is for something to go into the 40W C02 Laser cutter and engraver with blacktooth

You can find the wiring diagrams for the blackTooth on step 105 and 106 on the list of instructions on the blackTooth page. Step 105 pertains to the parallel breakout board and step 106 pertains to the USB interface board.

WHERE ARE THE WIRING DIAGRAMS FOR BLACKTOOTH LASER CUTTER IN INSTRUCTIONS?

We have one in the works. It is a 4'x8' machine that will house the 80w laser tube on the gantry. The machine is bout 2 months out as of 1/7/2014.

Do you have a larger kit for the Blacktooth Laser? I need a laser with at least 80watts of power.

On the blackTooth laser cutter and engraver, the ventilation is at the back and there is a slit at the bottom front so when the machine is placed on a surface, the air will move from the front of the machine and out the back through the ventilation. This will move the particles past the mirrors and tube output efficiently with a reduced likelihood of building up on these important surfaces.

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.

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 LASER CUTTER?

Where can I get the spec for the Cnc machine for the machine in the book build your own Cnc machine I tried the web page but no mesurments that I found

The digital signal portion of the CO2 laser tube power supply has various terminals for signal power, signal gnd, laser intensity and engaging the laser (turning it on or off). The TL and TH are triggers to turn the laser power on or off. These may be labeled L or H on some laser power supplies. You can use either TL/L, or TH/H to control the laser.

If you use the TL or L terminal to control the laser:
If a low signal (gnd) is present at that terminal, the laser will turn on. If a high signal (5v) is present, the laser will turn off.

If you use the TH or H terminal to control the laser:
If a high signal (5v) is present at that terminal, the laser will turn on. If a low signal (gnd) is present, the laser will turn off.

You should first test the control signal from the interface with a multimeter to make sure the laser will be controlled correctly before powering the laser power supply

On the blacktooth machine wiring diagram for parallel breakout a wire goes from 6 on the BOB to TL on the laser power supply. My power supply has an"H" followed by a "L". Which is correct? I've connected to the "L" but the laser appears always on.

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.

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

We will generally consider a change in dimensions or machine features if the change will be beneficial to other users as well. This is due, in part, to the time it takes to make such changes and that it maintains the desired functionality and expected safety.

What dimensional changes do you wish for the blackTooth?

Additional Information:
I was hopping to be able to have a cutting surface of 2' x 4'

Additional Information:
We have that size in our queue to be designed. However, you may be more interested in the laser adapter we are designing for the existing CNC machines to house a laser tube on the z-axis of these machines. This will be a quicker turnaround.

Additional Information:
Is there a time frame possibly to having this adapter made as well as cost? I am possibly looking to start a business so I am looking for something I can use to mass produce some specific parts.

Additional Information:
There is one project that takes precedence to the adapter, so I would expect in two months time.

As long as you have enough air blowing at the cutting location, you shouldn't have a problem with charring. A 40 watt laser should be able to cut through 4 ply chipboard.

There is a th or tl on the laser power supply that serves as the trigger on a high or low signal. There is also a potentiometer "in" terminal that will accept a variable signal from 0v to 5v to control intensity. You can use either of these features to fire the laser tube.

If you have gotten grbl to work, then, no doubtedly, you have the expertise to know the output features of grbl. If grbl allows a pwm output, you can tie this to the potentiometer terminal on the power supply. Otherwise, you will need to use a digital output to control the power supply using th or tl.

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.

It sounds like you got a misprinted book. If you purchased it from us, please contact us directly for a replacement. If you bought it from Amazon or a third party, you'll need to contact them. General information about lead screws is available on this website and at buildyourtools.com.

Just bought Build Your own CNC Machine book. It is missing the chapter on lead screws that is described on page 181 at the end of Chaprer 16. Where can I get this info?

The motor is helped by the mechanical leverage of the screw. The 425 oz-in motors that are included in the standard electronics combo has very high torque for that type of machine. You will have no problem using that motor for the book machine.

We use that motor for very heavy spindles on the blackToe and blackFoot CNC Machine kits.

You will need to do the mechanical leverage calculation along with the torque of the motor to determine the actual weight it will lift. The calculation will need to consider the type and pitch of the screw and it would also consider the gravity constant of 9.8 m/s/s.

If you need me to determine this formula and work out the calculation based on the screw you are using, please let me know.

Additional Information:
thank you for the reply. I would be really good to know the calculation. The lead screw is 1/2" diameter with 13 TPI. Please provide the calculation. And one more question. If I am cutting 18mm MDF with 6mm cutting bit (so 6mm pass), what can be the maximum speed rate of cutting and spindle speed of router?
thank you
