The parallel breakout board has the db25 connector for data and the USB connector for power. Connect the USB from the computer to the parallel breakout board so the breakout board will have 5V of power coming from the computer. The db25 connector (connector with the 25 pins) receive data signals for each pin from 1 to 17 and have respective numbered screw terminals, some for input and some for output (18 to 25 are gnd pins).

The parallel break out board on the Blacktooth machine has the parallel 25 pin socket, and also a usb socket. Should this usb socket be connected to the computer's usb port as well as the printer cable being connected to the printer socket?

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.

For safety's sake I would recommend a new board because they are inexpensive compared to the electronics that they support. Alternatively, it's possible that the one dead pin is a simple fix, such as a bad connection or solder joint; if you feel comfortable making those repairs then it could be worthwhile to check. Finally, if you are not using all the input pins, you could continue to operate the limit switch on pin 11 and hope for the best.

I have a breakout board and it appears that the pin 12 connection has failed: when i move my limit switches to pin 11 they work; they don't work on pin 12. Do i need a new breakout board?

For the integrated computer for the blackTooth, the hard drive doe not need to be formatted, but will require an OS (operating system) to be installed. Ubuntu Linux can be installed with the CNC integrated software from Linuxcnc.org. Windows can also be installed.

A parallel to USB adapter will not work. You will need to use a USB interface like the ones below:

Mach3 USB interface:

Additional Information:
To answer the question in more detail, the parallel port is actually an extension straight from the CPU and is also called the GPIO (General Purpose I/O) pins. These pins carry signals independently, hence the description as being a parallel port.

The stepper motor driver receives a pulse train (series of pulses). A single pin on the parallel port sends a pulse train to one stepper motor driver and stepper motor for a single axis. Another pin on the parallel port sends a pulse train to another stepper motor driver on another axis. This happens simultaneously as with the direction signals for each axis.

If a parallel port is adapted through a USB (using an adapter), the parallel port cannot have these signals happen in a simultaneous fashion and will cause the stepper motors of a CNC router or machine to be very clunky, if it works at all. To elaborate, the computer sends an instruction to the USB to send a high signal to pin 1, so it does, then another signal to pin 2, so it does. This is happening one after another. The speed at which this happens is reduced dramatically, and the position of one axis may now be out of sync to another axis.

The reason the USB interfaces (linked above) work is that the USB delivers broad instructions to the interface (to a microcontroller) and the interface parses the instructions and outputs simultaneous signals to the stepper motor drivers.

Hope this helps.

My computer doesn't have a parallel port connection. Can I use a usb to parallel port cable to communicate with my breakout board?

For our parallel breakout board (https://www.buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay#prettyPhoto/2/) the schematic will show the connections going from the BB to the drivers. The parallel breakout board uses the 25 pin parallel connection to communicate from the computer to drivers, and the USB is used to power the main-board itself, supplying 5V.

The electronics package I just bought from you (Book Build) is different from your wireing diagrams and video tutorials. Is there an updated wiring diagram available? Is the USB port on the breakout board connected directly to the computer USB to supply 5 volts? Thank you.

If your computer does not have a parallel port, all you will need is a low cost PCI parallel adapter card (these can be found on amazon for $15-$20). If you plan on using a laptop (not recommended) you can try to find a PCMCIA parallel adapter, but many people have frequent issues with this setup. A more expensive solution would be to purchase a USB smooth stepper board. Unfortunately, we do not supply any of these adapters and cannot attest to their reliability.

I have a parallel. breakout board. and no parallel port at the back of my computer do those parallel. cards. work with the breakout board?

Dealing with our USB BoB, it is really similar to the MK1 board, but is also loosely based on their DIY board as well. We have not seen that much of jitters or jerks, that we have noticed here while fabricating and testing the boards. We have not heard that many issues dealing with the board about abnormalities in running, unless we have not been notified in regards to customers who have used them under continuous use.

Its mentioned that your USB Breakout board is based on Planet-CNC's MK1 board. Planet-CNC on their forums mention that they've discontinued their MK1 because of a low buffer memory which caused jitters and jerks in the machine? Am I likely to face a similar problem with your board?

If you read the description the first uses a parallel interface for computer hookup. The second uses USB interface for computer hookup. The third utilizes an integrated computer which is built into the package thus you do not need an external computer.

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.

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?

The e-stop should be wired like a limit switch and can also be within the same limit switch circuit. Use one of the input pins to create the e-stop circuit.

1. Run a wire from the input pin terminal to the e-stop switch red side (one of the two terminals on the red side). The red side is NC (Normally Closed).

2. Run a wire from the other side of the red side of the e-stop switch back to the gnd terminal (or to the next switch - limit switch, NC terminal, then back to gnd, or to the next NC terminal of the next switch, do you see a recursive pattern here?).

The wire that you use for the connections should be shielded and the shielding and any other loose wire within the cable should be tied to gnd.

The 5V power required for the breakout board can be a simple USB male to male cable, that will connect from your computer to the board itself.
Now adding a external power supply make sure that it does not exceed a total of 5V and the standard 500 MilliAMP - 1 A.

Hello. I'm currently building my first CNC router, and I'm powering it with a 3 axis electronics kit that was purchased through your site. I chose to get the Mach 3 USB Breakout board, but now I'm wanting to try to use Linux CNC to work with the computer I have available. Will that work with this board?

Sure, connect O2 (output #2) on your mach3 USB board to the GND side of your relay coil. Connect the 24V power supply to the positive side of your 24v relay.

You will want to connect a flyback diode (1N4007) between the coil connections to make sure the coil back current does not damage the Mach3 USB board.

I recently purchesed a USB Mach3 breakout board and need help setting mach3 to use a relay to start the router can you show how to set the pins and which port to use on the board to attached the relay?

You will need PlanetCNC software for the USB breakout board and when plugging in the USB the computer should automatically recognize the board, however you can go into device manager to see if the USB terminal is working correctly.
The parallel breakout board; the USB is not a connection terminal rather than a power source, and the parallel port will be the communication terminal.
The items you will need for a water cooled spindle would be: water pump, silicon tubing(length desired by customer), a extension cord(from a hardware store(orange))(1 same gauge wire/length as extension cord).
