No, you should not have received two parallel breakout boards in your CNC kit. You can return the extra item using standard shipping with COD. Our apologies for the confusion and the inconvenience.

I will answer the other question as another FAQ. Please check the Customer Service page to see the answer to that question.

I have a 2000 WK 11–3 Z limit switches going to A c10r10 breakout board . Can I also use them as my home position as well. I need The wiring configuration

You can add a limit switch to either the USB or the parallel board. Please refer to the product pages for these items to view wiring diagrams.

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?

You will want to connect the homing switches (which may also serve as your near limit switches) to different input terminals. It's ok to add more limit switches with the home switches, but each home should be on independent inputs. For example, connect home X and any other limit switch to IN1, connect home Y and any other limit switch to IN2, and so on. This will allow you to properly use the "ref all home" button in Mach3.

Additional Information:
In the instructions (diagram 1) you show all the home switches connected in parallel? But here you say they need to each have their own inputs. "You will want to connect the homing switches (which may also serve as your near limit switches) to different input terminals." I dont see how the second and third axis can go home if the first axis has already closed the parallel circuit unless they back off a bit until the switch opens up again before the next axis goes to home? My machine has no limit switches so I assume they are home switches.

[575] I have finally got my limit switches wired and working - thank you. Can they also used as homing switches and if so it it just a question of looping the two inputs on the board i.e. the limit and home terminals IN2 to IN3

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.

Hi - I have wired in a breakout board (with relay) as per suggested wiring instructions (black toe 2X4). I want to wire in an estop but need some guidance on wiring. Also Mach3 is requesting I reset the estop, which suggests its expecting one? Can anyone help? Thanks. Miles

Yes, the Mach3 USB board has two terminals that require 24V connection. Most VFDs have a 24V output that can be used to power this part of the Mach3 USB board.

The V+ and V- on the Mach3 USB is not absolutely necessary to operate the CNC machine/router. The V+ and V- of the Mach3 USB board powers the outputs, inputs, and spindle's speed and control.

Here is the Mach3 USB link for more information:
https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

The new YL600 VFD we have in stock may not have this 24V output. There is a 12V terminal, but I have not tested that terminal if it outputs 12V, or if it is a 12V input. If you are only conecting limit switches to the Mach3 USB and need to power that portion, 12V will be sufficient.

I will delve into these aspects in far more detail on video.

Thanks and Merry Christmas to you as well!

Hey Guys, I have a brand new redleaf and 5x. In the final stages of wiring and wondering a few things. Can I connect the Mach3 USB board V+ V- to my frequency inverter (type YL600-2s-2k20)? If so where? Will your upcoming (part 2)video deal with this as well as final connections for limit switches and stop button? Merry Christmas!

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.

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 purchased limit switches from you mounted them on my machine and wire them to the breakout for using pin 12 and the ground on the breakout board, after a few minutes I got a message about a limit switch trip. Am I supposed to use the extra outport on the board instead of the ground?

NC mechanical switch configuration is supported. You can download the manual from this page (Mach4 plugin and manuals):
https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach4-mach3-USB-ethernet-Board

The pokeys57CNC controller has input terminals and pins for limit switches on each of the 8 axes. There are three separate inputs per axis, two for the actual limits of that axis, and one for the home position.

Connect each switch between the GND terminal and its respective axis limit terminal/pin. For instance, the limit switch will typically have three leads, COM, NC, and NO. In an NC configuration, the NC connects to the terminal/pin, say, Axis 1 lim +, and the COM connects to the GND terminal.

In Mach4, in the new device wizard, make sure to specify the correct option on the home and limit switches that matches the machine configuration.

can you use one switch per axis for home only?

Customer response:
I've tried all pins: 10, 11, 12, and 13. I get the same non-response in each case.

There may be a problem with the board. If you are using our parallel breakout board, we can ship you a replacement (call us), otherwise, you will need to determine the problem with the vendor of the breakout board you are using.

Additional Information:
I have tried 3 different breakout boards from 3 different providers and they all do the same thing My limit switches are microswitches wired NC with each axis wired to the BO Board. I have checked each circuit and all is OK to the BO board. each circuit has continuity at the board and when any switch is pressed the circuit breaks. Mach 3 does not recognise that the switches are even there. They are configured as active low Do you have a suggestion.

I'm having trouble getting Mach3 to recognize my limit switches. I've eliminated everything back to the breakout board. I can directly connect Input 10 to GND on the breakout board while Mach3 is in autorecognize mode and Mach3 doesn't acknowledge anything.

This is correct. You will need to use a method appropriate for the software you are using. Also remember that NC switches are typically wired in series, while NO switches are normally wired in parallel.

Limit switches for axis. The print shows that you can wire the limits either n.o. or n.c. so if this is correct I would need to tell the board in the software how to look at these limits, I'm either going to get an input or loose an input depend on how i wire it.

Each home switch needs to be on a separate input on the Mach3 USB controller. For instance, the x-home on IN1, Y-home on IN2, and Z-home on IN3. You can still wire the other switches on the same input, for instance, the IN can contain the X-home and X++ limit. The X, Y, and Z homes can still serve as the limit --.

Additional Information:
So I need 3 of 4 INs only for the home switches??? The remaining one for ++? What about E-Stop and Probe?

Additional Information:
Please have a look at the wiring diagram you show below. There are all limit switches at IN2 and all home switches at IN3. Makes sense to me.

Click the link to add information to this solution:
[575] I have two limit switches for X, Y and Z axes connected to only one input terminal. As usual, I also want to use them as home switches. But after the first axis touches its home switch, I get an emergency stop because of "activating a limit switch". Mach 3 normally knows when to use a limit switch for homing. Which detail in the depths of Mach 3 did I forget?

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?

Absolutely! You can have almost unlimited limit switches and home switches on this controller. It all comes down to the wiring scheme used. I recommend the home switches be on separate input terminals. For example, IN1 would have the X home switch, IN2 would have the Y home switch and, IN3 would have the Z home switch if you plan on using home switches for the Z axis.

Adding the limit switches, these can be located on any input you want, even on the IN1, 2 or 3. The wiring scheme I like to use is as follows:
- IN1 has the X home, X limit ++, and X Limit --
- IN1 has the Y home, Y limit ++, and Y Limit --
- IN1 has the Z home, Z limit ++, and Z Limit --

In most cases, the Limit -- is the same switch as the Home switch.

These can be wired as NC (Normally closed) as a serial scheme, or as NO (Normally open) as a parallel scheme.

To understand the limits and wiring schemes, check out this video:

[575] Hi, for the manage the limit switches, is it possible to have, for example, the same limit switch for X-- and X homing? And what is the configuration in mach3? In my CNC machine they are in the same position. Thank you

Any of the following power supplies will be fine for powering the Mach3 USB controller:
https://www.buildyourcnc.com/item/24v

however, the limit switches do not need high current, so the following power supply is sufficient for the task of connecting limit switches:
