where can I find wiring instructions for the Mach3 USB controller?

You will need a 24V DC Solid State Relay to accompany the Mach3 USB Motion Card as the outputs on that motion card requires a 24V Power Supply.

I need wiring instructions for the breakout board you sent yesterday. It is not like the one in the videos and I don't know where to connect the 5V. No data sheet or anything.

To connect the stepper motor drivers to the Mach3 USB interface card, you will need to follow the wiring diagram here: https://www.buildyourcnc.com/Documents/Electric%20Wiring%20Diagram.pdf
which can be found here: https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board along with all of the other manuals associated with that interface card.

Please note that the DC+ and DC- on that wiring diagram (power supply to thye stepper motor drivers) is not correct. The DC- is connected to GND on the drivers and the DC+ is connected to VCC on the drivers. Typically, the DC+ on the power supply is labeled V+ and the DC- is labeled either COM or V-.

If you are having any issues with the wiring, please let me know and I will elaborate. Thanks.

The eyebolts are used in the squaring of the machine. I would use a standard carpenters square and first run the end mill along the edge of the square to first make it parallel with the long axis. Then run the end mill along the other edge with the short axis and adjust the eye bolts and chain according to the angle that the machine is out of square.

A 24V connection to the USB motion card is only needed if you are using limit switches (inputs), powering the spindle/VFD speed and direction, and for the outputs, for powering other devices (mist, coolant, etc.).

If you are using a VFD (Variable Frequency Drive, also called Inverter) for a spindle, they typically have a 24V out terminal that can be used with our USB motion card. If you are not using a spindle/VFD (we highly recommend one), then you will need to purchase a 24v power supply to power that side of the board.

The outputs mentioned above are to connect to external devices and will require a relay (a mechanical switch that is controlled by a digital signal). This mechanical switch can turn on a device like coolant and mist, or even a router, if you are using one. A relay is required to turn on these devices because the devices are typically higher voltage, like mains (110v or 220v). So, a relay can turn on or off a high voltage device with a lower voltage (24v) signal.

This is correct if it is the Mach3 USB controller. You will also get a rapid flashing led if you jog the machine (assuming the machine is not in reset mode or e-stop mode).

The instructions for installing the USB board say there should be a blue LED light up when computer is connected. I get a flashing red LED that goes solid when I start

The power supply that is used to power this controller must be 24VDC maximum. Any higher voltage and the controller components can be damaged. The 24VDC power supply doesn't need to be a high amp power supply. I would recommend This power supply: https://buildyourcnc.com/item/electronicsAndMotors-power-supply-24v-1a-dc

The motor that is attached to the 4th axis is wired as follows:

The motor should have red, green yellow and blue wires coming form the motor. The red and green are paired as one coil and the yellow and blue is paired as the other coil. You can wire the motor to a 3.0 amp driver with red to A+, green to A-, Yellow to B+ and Blue to B-

Can you tell me which part the countersink holes are located?

When building the gantry, the first screws the video shows are to be counter sunk. However, there are no counter sunk holes on any of the parts I received. I have a picture I can send if you tell me where to send it.

You can use a Pickit 2 programming to load firmware onto the usb driver. The USB use a Microchip pic microcontroller. If you can manage writing a program for the Pic microcontroller and have a Pickit 2 firmware uploader (programmer), you should have no problem.

Does the USB controller come with driver installation instructions so we could create our own user interface to communicate with the motor?

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

The relay is only used for devices like routers, spindles, coolant, mist, etc. The relay works like an automatic switch and will allow current to pass when the relay is engaged.
