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?

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.

What do I need to do to my breakout board to turn the router motor on at the beginning of the program and off at the end?

Connecting drivers from a controller to the driver does not require relays. A controller typically has pins or terminals for Step and Direction. These terminals connect to the driver's Pulse and Direction terminals. For instance for the X axis: if you are connecting from the Mach3 USB controller, you would connect the XD (X axis Direction) terminal to the Driver's DIR+ terminal, and the XP (X axis Pulse) to theDriver's PUL+ terminal, and the GND from the controller to the PUL- and DIR- terminals.

I have thorough step by step instruction for two controllers:

Any of the following power supplies will be fine for powering the Mach3 USB controller:

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

What power supply do you recommend for the spindle and limit switches if I buy the USB Mach3 breakout board?

The Mach3 USB board will fit in the redLeaf, but you may need to modify the Plexiglas top for proper mounting. However, the redLeaf has the proper parallel GPIO on the motherboard for use with the Parallel breakout board. If you have a laser on the machine you are using, then I would urge you to maintain the parallel breakout board as the Mach3 USB board will not work correctly using the Z-direction pin and you will need to determine how to use the output pins onthe USB board to ensure proper laser functionality.

The USB interface that we sell only works with planet-cnc software. We will be developing our own USB board and plug-in that will work with Mach4 very soon.

The Mach3 USB controller only works with Mach3. We have a controller that works with Mach3 and Mach4 called pokeys57CNC controller.

I recommend using a wireless pendant rather than one that is wired to the controller.

Here is a link to one on Amazon.com: https://amzn.to/3r3AfTm

[596] I am new to CNCs, curious to know what I need to look for in a pendant that would be compatible with this board and Mach4?

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.

I need wiring diagram from mach3 breakout board to hy inverter

I would recommend using a separate 24VDC power supply for the controller. The 24VDC that is connected to the controller is used for delicate input signals and output signals that control external devices. To keep interference and possible current and voltage fluctuations at a minimum due to the motor load, a separate power supply would be best.

Click the link to add information to this solution:
[575] Can the 24VDC supply used for the interface board be the same supply used for stepper drivers, or do you need separate power supplies? If not, does GND and DCM need to be isolated?

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.

Do you have a wiring diagram for your breakout board and the SuperPID?

I would suggest using the NPN proximity sensor for the Mach3 USB or the Pokeys57cnc. The proximity sensors have a top DC voltage limit of 30 volts, so it would be best to use the 24V power supply that is used to power the controller. Both controllers have a 24V power requirement, so that is convenient.

The blue wire of the proximity sensor is the GND wire and is connected to the 24V power supply's V- terminal. The brown wire is the positive wire and is connected to the V+ terminal of the 24V power supply. The black wire is the signal wire and is connected to the input terminal of the controller.

Click the link to add information to this solution:
if I wanted to use your inductive proximity sensor's with your USB interface board what would I need besides the sensors I would be using 5 of the sensors.

The USB port on the Parallel Interface board is necessary to supply 5V power. Connect with a USB cable to a USB source.

HOW DO I CONNECT A TOUCH PLATE TO THE BREAKOUT BOARD?

The dimensions for our USB breakout board are:

L: 2.745"/ 69.723mm
W: 2.244"/ 56.9976mm
H: .501"/ 12.7254mm

Currently we do not have a CAD model on hand.

What are the overall dimensions of the USB interface board? Is there a CAD model available?

CP+ to COM
CP- to STEP
CP+ to CW+ (small jumper wire)
CW- to DIR

Additional Information:
If the driver does not have CP or CW labels, the CP is Step and the CW is Direction or DIR. If you connect the 5v to CP+ (or Step+) and CW+ (or DIR+) and the pin to CP- (or Step-) and another pin to CW- (or DIR-), then in software, the configuration for the step on that axis must be active low. Otherwise, if you connect the GND to CP- (or Step-) and CW- (or DIR-) and the pin to CP+ (or Step+) and another pin to CW+ (or DIR+), then in software, the configuration for the step on that axis must be active high.

Additional Information:
If you have a driver that is labeled pul, dir and ena: Pul+ is the Step+ and Pul- is the Step-. Pul is short for pulse. A pulse will create a step. Don't worry about the enable terminals.

On the x-axis, pin #2 can go to pul- and pin #3 can go to dir-. The 5v will go to pul+ and dir+. The configuration for each axis for step will be active low and toggle active low for the dir on each axis to make it go in the direction desired.
