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.

As I am building my 20" x 24" laser engraver cutter, I notice that there is no parallel port on the onboard computer and I have the parallel breakout board any answers?

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.

MY COMPUTER DOES NOT HAVE A PARALLEL PORT. HOW DO I INTERFACE WITH THE BREAKOUT BOARD?

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

Mach3 USB interface:

Poeys57CNC Interface:
https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach4-mach3-USB-ethernet-Board

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.

IF MY COMPUTER DOESN'T HAVE A PARALLEL PORT, HOW DO I RUN THE MACHINE?

If you have an existing PC with a parallel port you will not need to purchase the onboard computer system on the blackTooth laser cutter and engraver. You will want to purchase the blackTooth laser engraver that comes with the parallel interface (breakout board). If you have an existing CNC machine that is being used with this PC, you can disconnect the CNC machine and connect the blackTooth to this PC. You will want to have two configurations for your control software.

Additional Information:
We have a version of the blackTooth that is 110v and 220v. We generally determine which is sent according to the requirements of the customer and in what country they live.

I'm interested in purchasing your black tooth laser engraver and am curious what setup to get. I already have a cnc wired via parallel port to my PC. Do I need to purchase the black tooth laser with the integrated computer or can I just disconnect my current cnc's parallel port and connect it to the black tooth laser engraver? Also is the black tooth 110v?

Sure. If you had your own computer to start with and now need a replacement for it, consider our redSprout and redLeaf systems.

Mach4 is designed to run in both 64 and 32-bit computers and operating systems, however, the parallel port interface will not work with 64-bit windows. The easiest solution would be to use a more modern CNC controller, like the:

pokeys57cnc that I sell
https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach4-mach3-USB-ethernet-Board

Or other options like the Smoothstepper board that I do not sell.

Both are great options.

Do you have anything connected to the relay?

Additional Information:
is the relay controlled by a pinout on the BoB?

Additional Information:
Nothing is attached to the relay pins I am only using 2 and 3 and 5v for x driver and led indicator, 4 and 5 and 5v for y driver and led indicator, and 6 to fire the laser and the led indicator. I am also using a 5v out for the laser power control circuit and one pin of the 5k pot. Ground is shared on the laser power supply, the cnc power supply and the x and y driver. I am using the computer motherboard supplied by Buildyoucnc running ubuntu 12.04.5 LTS and linuxcnc. Bios is set to use ECP, I have tried normal and I have tried EPP, all with the same results. If I plug in the parallel after the computer starts up it doesn't switch but I can't control either axis motors


Additional Information:
Laser is currently not connected for safety reasons


Additional Information:
I am using the parallel BoB for the 40 watt C02 Laser Cutter and Engraver(blacktooth), with the supplied integrated computer running Ubuntu 12.04.5 LTS and linuxcnc. Right now, when I have the parallel header connected to the BoB(as well as usb power supplied by the computer) and I start the computer, I am able to see the first splash screen of text indicating that the computer is starting up, then the relay on the BoB switches, turning the computer off and then back on again. This happens over and over again and the computer cannot fully start into the linux os. If I unplug the parallel cable from the BoB, I can start the computer, sign in and then plug the BoB back in without it shutting down the computer. Can anyone explain why this happens? I should also say that I cannot talk to the steppers in stepconfig of linuxcnc, I get to the test this motor section and nothing happens when I try to jog either the x or y motors. In the y config, I actually triggered the relay and sent the machine back into the start up failure loop I mentioned in the beginning.

Additional Information:
Fixed this problem, the parallel cable was not seated well, found some screws to make a strong connection, now that part is working. Unfortunately, the stepconfig in linuxcnc is still not talking to the motor drivers and the setup for determining steps for inch in the build instructions is nothing like the set up in linuxcnc. In the instructions it says motor steps per revolution*microsteps/pulley pitch per tooth*number of teeth and in this case the recommended input would be (200*16)/.08*20 teeth = 2000 steps per inch the formula in linuxcnc is very different

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).

If you are getting the "Communicating Unsuccessful!" error when you are trying to communicate between LaserCAD and the AWC608 Laser Cutter and Engraver controller (after you have already tried installing the USB driver from the LaserCAD setup procedure), these are the steps you will need for a successful communication:

- Open the Device Manager window (right click on the start menu and select Device Manager)
- When you plug the USB cable from the AWC608 Laser Cutter Controller (USB Type B connector) to the computer, you should see a new item in the Device Manager, possibly under "Ports (COM & LPT)", or under "Other Devices". It may show as an item under "Other Devices", possibly FT245R and has an "!" in a yellow triangle.
- Download the latest FTDI drivers from: http://www.ftdichip.com/Drivers/D2XX.htm
- Unzip the files to a folder that can be easily browsed.
- Right click on the item that appeared in the Device Manager when the cable was plugged in between the Laser Cutter AWC608 controller and the computer.
- Click on update driver
- Select the procedure to manually install the driver and browse to the folder containing the FTDI driver and follow the step in the driver installation wizard.
- The item should now be located under the "Ports (COM & LPT)" and should be named "USB Serial Device (COM#)". The # will be the number you will use in the LaserCAD software.
- In the LaserCAD software, click the "Select Mode" at the far top right of the Laser CAD user interface.
- Make sure USB mode is selected.
- If the Machine name with the correct COM number is listed, select it and exit the dialog window. Otherwise, click on "Add" and fill in the details with the new COM number.

The greenLean machine comes with the entire structure and features a 4'x8' cutting area. You will still need some hookup wire to connect the electronics and silicone tubing for the water to and from the spindle.

greenLean Machine: https://buildyourcnc.com/item/cnc-machine-greenLean-v1

Thanks for answering my last question. So I have two follow-up questions from the response. The green leaf stands vertical is it designed for the material to be cut without falling free once it is cut through? And second question: you metioned water running to the spindle is this a cooling system for the spindle?

You would use holding tabs to keep the parts from falling out of the cut areas. Holding tabs are generated as part of the CAM file. Yes, this is the way the spindle is cooled. This is far superior to air cooling. Air cooling will blow the chips all over the shop.
