how do I connect the parallel breakout board?

Here is how to connect your router to the parallel breakout board through the on-board relay. You will need a spare extension cord. You will need to remove a portion of the outer jacket of the extension cord to expose the white, black and green wires (white = neutral, black = live and green = ground), understanding that the neutral and live create the completed circuit.

See this image of a similar connection. The terminal has the same connections.

Image of the relay terminal:

The live/black wire would be cut and one end of the cut would be secured into the P terminal and the other cut end would be secured into the S terminal. The live and ground wire would be uncut and travel from the plug to the router.


Additional Information:
You can also connect other high powered devices to the breakout board using any of the output terminals. You will need to supply extra relays like the one shown here:
https://www.buildyourcnc.com/item/electronicsAndMotors-breakout-Relays-relay-board-250V-12A-5V

Or you can find SSRs (Solid State Relays) that will accept 5v to drive the relay coil. Make sure the SSR will protect the 5V line from Back EMF as there is a coil in the relay. The one we sell contains a fly-back diode to protect the 5v terminal.

Getting continuity from the x--/x++ might not mean it is a faulty board, unless they are bridged, so both get a pulse rather than one. But to check if you might have a opposite connection for those input:

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 suppose you are trying to determine how to connect the VFD tothe relay on the breakout board. This is possible, however, not recommended as there is a more robust way to connect the VFD to mach3 or mach4 that allows that CNC machine control software to control the speed and other features of the VFD.

Follow the instructions from this question (number 13383):
https://buildyourcnc.com/FAQ/13383

To get to this answer, you can also ask this customer service "How can I connect my spindle's VFD to mach3?"

Additional Information:
If you still want to connect the VFD through the relay, I will clarify this instruction on this question tomorrow as I don't have the information in front of me at this moment. Thanks.

If the motor has 8 wires, you will need to wire the stepper motor in bipolar parallel. This motor (425 oz-in) is wired as follows:

Red and Blue wires to A+ on driver
Yellow and Black wires to A- on driver
White and Brown wires to B+ on driver
Orange and Green wires to B- on driver

Use the datasheet associated to the motor that you purchased. Use the bipolar parallel configuration to optimum performance. The datasheets are located in their respective motor product pages. Just click on the motion electronics at the left and scroll down to the motor you have and click on the title, or datasheet link next to the motor. The datasheet will either be in the form of a pdf, or within the instructions on that product page.

How do I connect my motor wires to the driver?

Sure, the USB interface has a place for 4 axes of limit switches.

Each axis can have two limit switches: one for the ++ (positive) end and one for the -- (negative) end. The positive end would be the limit switch at the end of the machine that, say the machine has a 4'x8' area, reaches a bit after the 8 foot mark. The negative end would be the limit switch behind the 0 foot location behind the origin. If the origin is in the middle, the negative would be at a little more than the -4 foot end and the positive would be at a bit more than the +4 foot end. Note that you can have more than one switch on each pin where the NC is connected in serial fashion and the NO is connected in parallel fashion (this can be seen on the diagram in the multiple limits switch section). The software configurations for the limits switches are under File -> Settings -> Limit.

A typical limit switch has three connections on it. These connections consist of COM (common), NC (normally closed) and NO (normally open). The COM would generally go to GND and the NC or the NO would go to the pin. If the NC is used, then the the switch is constantly connected until the switch is pushed (engaged) then the connection from the pin to gnd is broken (open). Use the settings in software to set whether in NC or NO configuration.

Let me know if this information was helpful (or not) by adding information to this question. Thanks.

User response:
Thank you very much for this helpful information. I'm still a little fuzzy on how the 6 limit switches physically connect to each other and to the USB breakout board. You've stated one switch (home) goes to positive and another switch (limit) goes to negative. Are all the GND prongs from all 6 switches connected to each other and going to GND on the breakout board, or no? And the NC prongs, how exactly are they connected to each other? And to the board? There has to be a diagram somewhere shows this visually, no? I don't know how to wire the switches in series or in parallel. I have already physically installed all the switches on the machine and ran the wires to where the board is. Now I just need to know where to plug these wires into the board. Also, taking into consideration that I'm using the Planet CNC software, the only settings I have pertaining to limit switches is "Enable/Disable" for each axis, and the actual limit for each axis. Nothing about NC or NO. Is that only in Mach3?
Thank you.

buildyourcnc response:
On the USB interface, the COM on the switch connects to GND and the NC or NO connects to the input pin (i.e. x++, y--, etc.)

Limit switch configuration is rather difficult to understand, especially with series and parallel. You can think of series as a single wire going from GND to the axis letter input terminal (i.e. X++ or X--). If the wire is broken, then the circuit is open (or the switch is engaged in a normally closed scenario). Normally closed is like an actual wire, and when engaged, the switch "opens" (breaks the wire). This is why we recommend in some systems that you can put many switches in series on a single pin. When one of the switches is engaged (breaking the connection) then the entire circuit of switches is broken and the machine stops.

In a parallel scenario, the state of the circuit is always broken until the one of the switches is engaged and the circuit is then closed or connected. The topology looks like a ladder. All the switches connect to both sides of the ladder and the switches are like the runs of the ladder (the horizontal bars that the feet are placed while climbing). Imagine all of the switches broken in this scenario (normally open). It would be like the ladder could be split in two, but if one of the ladder runs (switches) is closed by engaging it, then that run would connect both sides of the ladder and the two sides of the ladder would have a connection.

There is a diagram on the USB page of the various limit switch configurations. If you need more information (visual and/or otherwise), please let us know and we will immediately add that information to benefit everyone.

I have nearly completed the CNC machine from the book, but I am using it with a USB breakout board, and have no idea how to wire the 6 limit switches to the board. I'm having difficulty following the diagram on the USB breakout board screen. Can someone please help me?

SketchUcam will output gcode which standard CNC control software will typically interpret, execute and control CNC machines. So, there is no problem using SketchUcam. However, our CNC machine control software that use our CNC machine interface boards require Windows OS, of Linux. The Mach3 USB board will only run with Mach3 control software which runs under the Windows OS. The parallel breakout board can run under Windows or Linux OS and the computer must contain a parallel port.

It is not necessary for a wiring diagram for the breakout board to the SuperPID controller since you are only going to connect two wires from the breakout board output terminals of your choosing to the SuperPID controller. The only thing remaining is to configure Mach3 so that the spindle control section serves as the SuperPID controller.

To setup this configuration in Mach3, go to your ports and pins dialog box (config menu -> ports and pins). Click on the spindle setup tab. In the Motor Control Section of the dialog, check the box for Use Spindle Motor Output and check the box for PWM control. Change the PWM Base Frequency to 50Hz.

The breakout board has a relay installed and uses the terminals labeled S, O and P. The following link explains the operation of this relay and how to connect the terminals:
https://www.buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay#prettyPhoto/8/

You will run your power cord (use an extension cord rather than the actual power cord of the router) through the relay using the S, O and P. The P is a general connection and the S is normally closed (S and P is connected when the relay is not engaged) and O is normally open (O and p are not connected until the relay is engaged).

There are three wires in the power cord: neutral (white), live (black) and earth ground (green). You will run your neutral wire (white wire) through this terminal. At some point in the power cord, remove the outer insulator and expose the three wires within. Cut your neutral wire and strip both ends of the cut. Then insert one end in P and the other end in O (normally open), so Mach3 or other control software you are using will engage the relay and the router will turn on.

You will need to setup your control software to turn on the relay using Pin #16 as this is the digital signal pin that controls the relay.

Additional Information:
Are you able to install a newer version of Mach3? If you are worried that your configuration will be lost, you can save the configuration by copying all of the XML files from the Mach folder. The XML files contain all of the settings that you applied in Mach3. Just in case the XML files are not compatible with the new version, make sure not to erase the current Mach3 that you have on the machine.
