There are many ways to wire an emergency stop switch. The simplest, and arguably the most certain, way is to wire the switch into the incoming power so that throwing the switch kills all power to every part of the machine. Here is a diagram showing how a customer wired such a switch on their blackTooth laser which you could adapt to your needs. http://www.buildyourtools.com/phpBB3/viewtopic.php?f=12&t=4872

Alternatively, you could use an input pin on your USB board. The wiring would depend on whether and how you might be using limit switches (single or multiple switches; normally open or normally closed). Our website datasheet for the USB board is at https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/ and shows how to configure the switches for each set up. If you use this method, you'd essentially wire the e-stop as a limit switch.

I recently purchased 3 axis electronics with the USB controller board. I'm trying to install an E-stop switch. Where do I connect that on the controller board?

Controlling a 3-axis or 4-axis motor configuration, you will need the following items drivers/motors/controller. Our electronics combo comes with the items mentioned and with power supply/miscellaneous items.
The only other item needed will be a computer (with controller software) to communicate and view controls of your motors.
Using the Parallel breakout board will use Mach 3 software, and USB will use Planet-CNC software.

hey, where can i see the steps how can i control 3 or 4 step motor? can i use the Axis Electronics Combo? or i need to connect controller?

The Mach3 USB will not work with Linux CNC. You can use our parallel breakout baord instead (if you have a computer that has a parallel port available).

Here is the link to that interface:

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?

I would not recommend slaving an axis using the method of taking an additional axis from the USB interface. Instead, wire both drivers to a single axis on the USB interface. This will insure perfect signal output to both drivers. If you requre the motors to spin in opposite directions, simply wire one of the motors to the driver reversing the coil A and B connections, or use a hex inverter (https://www.buildyourcnc.com/tutorials/Tutorial-Two-Motors-Spinning-Oppositely-On-Single-Axis).

I purchased a USB Breakout board, motors and drivers, paid for CNC USB Controller Software and I CAN NOT "Slave" an axis, but there is an option to do that. The moment I connect USB Breakout Board "Slave" option becomes shaded and I can no longer select it (becomes not functional). What is going on? Need help asap. Thanks

I purchased the 3 Axis Heavy Gantry Electronics /w Pokeys57CNC controller and the motors supplied only have 4 wires coming out of them (R,G,B,Blk). Your wiring video shows wiring 8 cables. do you have a video showing how to wire the 4 wire version?

Unfortunately, we don't sell the planet-cnc controller anymore. They made a change to their software that prohibits us from creating the open source board.

We do sell three other boards that may work for you.

The Pokeys57CNC board is the mose feature rich and will work with both Mach3 and Mach4:

The MAch3 USB board is a good inexpensive interface that will work well if you need the interface to be USB only:

I purchased the greenbull with the electronics assembled, where are the wiring schematics to wire to 110 volt inverter?

The Mach3 USB controller requires a minimum of 12V and a maximum of 24V to the DCM and 24V terminals. The DCM is the GND or DC negative terminal, and the 24V terminal is the positive terminal.

Attaching two motors in parallel is possible, but you will need another motor and driver for the opposite side. Each motor must have its own driver to work accordingly and fluently. The two can be wired together, to the same pins on your breakout board and set the dip switches on the driver to match the ones on your x-axis(ex). But remember to view the orientation of the motor and which way it spins, since it is on the opposite side it will have to be orientated correctly to move in sync with the other motor.

I just finished building my first CNC with the electronics I purchased from you and I am already thinking about improving it. I would like to build a 2 motor X axis solution. Is it possible to attach 2 parallel motors and drivers to the BlueBrew Breakout Board? If so, how?

If the sensors are NC (normally closed) you can wire them in series. If the sensors are NO (Normally Open) you can still wire them to the same input, but the wiring needs to be in parallel (like a ladder). I have more information on the following video:

[788] Thanks for the oportunity to ask, I am building a cnc and using npn closed sensors could you help me with the conection of these, do i still connect them in series if i use more than two in each axis. Also you mention that a stop switch should be connected grd and input to the controller would that be done after the 24v power supply. Thanks r

with parallel port controllers, you have the ability to jog using two axes at the same time, but with USB controllers, this is not possible.

When you plug the USB controller into the computer using a USB cable, and the planet-cnc software is running, you will be presented with a dialog box that will contain a text box for the key that you received from the planet-cnc folks.

Yes, you can connect a THC, Torch Height Controller, with the Mach3 USB controller. The THC uses the inputs to determine if the z axis needs to move up or down according to the arc of the plasma torch. The THC connects its outputs to the inputs of the controller so the controller will be informed of the states of the plasma torch.

I am interested in using the Mach3 USB interface board. I was wondering if there was a way to run a torch height controller with this board for use with a plasma cutter, and if so do you know of any THCs that will work. Thank you.

Identify the Control Signals: First, determine which control signals from the DB25 interface card are used for spindle speed control. Typically, these are PWM (Pulse Width Modulation) signals or analog voltage signals.

VFD Configuration: Your VFD should be configured to accept the type of control signal your DB25 card provides. This involves setting parameters in the VFD that correspond to the type of input signal it will receive for speed control.

Wiring: Connect the appropriate output pins from the DB25 card to the input terminals on the VFD. This usually involves connecting the PWM or analog output to the corresponding input on the VFD. Make sure to consult the manuals for both your VFD and interface card for specific wiring details.

UCCNC Settings: Configure UCCNC to output the correct type of signal (PWM or analog) that matches your VFD's configuration. This is done through the software's spindle setup section.

Test and Adjust: Run some tests to ensure that the spindle speed is being correctly controlled by UCCNC. You might need to tweak settings in either the VFD or UCCNC for optimal performance.

HEY ! I HAVE PURCHASED A VFD WITH MATCHING SPINDLE 1.5KW AND CONTROL PROGRAM UCCNC. MY INTERFACE CARD IS DB25, THE QUESTION HOW DO CONNECT TO DB25 SO THAT CAN SPEED UCCNC? SINCERELY "CNC BEGINNERS"

If you want speed control, it is recommended to use the RS-485 connection on the VFD and use the control program such as Mach3 to communication serially with the VFD using this RS-485 connection.

If you would rather use a controller such as the PMDX-107 to simulate the effect of a potentiometer using the Aref, Aout and Agnd and the Rev/Dir and Fwd/Run terminals to control operation and direction, you can connect those to the VFD.

PMDX-107 Aout connects to the VI (analog voltage in). This is like the wiper on a potentiometer.
PMDX-107 Agnd connects to the ACM terminal on the VFD for Analog common.
PMDX-107 COM connects to DCM terminal on the VFD for Digital common.
PMDX-107 Fwd/Run connects to the FOR terminal on the VFD for Forward.
PMDX-107 Rev/Dir connects to the REV terminal on the VFD for Reverse.

Refer to your PMDX-107 manual to correctly configure your dip switch settings and make sure to calibrate (tweak) the speed control using the trimmer next to the terminals on the PMDX-107.
