Customer Response:
My inquiry is for the Planet CNC USB and 5v relays.
I am 99% finished with my 2 axis lathe build and this is the last item for me to conquer.
I want to control power to router, and vacuum with the BOB going through the 5V relays purchased on this site.
Thanks again.

Using the Mist, spindle or flood pins...

Buildyourcnc response:
There is an IN, GND and 5V for the digital side to engage the relay. There is an S, O and P for the power line of the device to be controlled.

The 5V and GND must be connected to the 5V and GND from the USB board. The IN is the wire from the output terminal (i.e. mist, flood, spindle).

For the power side, here are the scenarios:
- P to O connection is normally open
- P to S connection is normally closed

So, if you have the power wire that would plug into the wall, the L "black" wire from the power cord will pass through this part of the circuit (cutting the wire and one end in the P terminal and the other end in the O or S terminal). Generally, the P to O is used as this connection is normally open and when the relay is engaged, the circuit will close allowing the current to flow through that wire.

I need wiring instructions for the ST- USB MOTION CARD

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.

Need wiring diagram from mach3 USB breakout board to inverter.

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.

We are currently getting it completed for us to post it under the 2.5A stepper driver page. However here is the correct wiring procedure.

First: Wire the 24V power supply to the 2.5A driver, by wiring +V on the power supply to 12-24V on the driver. Next wire the COM on the power supply to Ground(GND) on the 2.5A driver. GND on the driver will also go to the GND on the USB board, for specific axis. (additional 3-4 wires connected to ground will be needed for the other axes as well).

Second: Wire the USB board to the driver(one driver per axis on the USB board):
CP on the driver will go to CP on the desired axis on the USB board.
CW on the driver will go to CW on the desired axis on the USB board.
5V will go to the VCC pin on the keyboard jog pins on the USB board (check schematic here: https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/).
GND on the USB board to GND on the driver. (as specified in step 1).
EN is not used.

Personal Note:
I would recommend that you crimp the VCC pin to a wire which could be split for the other axes as well, each driver will need 5V.

Third: Wire the stepper motor to the driver, (using either the Nema 23 100-oz or the Nema 17 62-oz stepper motors, the wiring will be the same. For the Nema 23 the yellow and white is not connected.)
Black to A1
Green to A2
Red to B1
Blue to B2

Fourth: Repeat steps 1-3 for each driver/motor per axis.

Mention: Remember that GND on the driver will also go to the GND on the USB board for specific axis, and VCC pin on the USB board (keyboard jog) will go to 5V on all drivers for each axes as well, each driver will need 5V!

Is there a complete wiring diagram for the Medium Combo Kit with the usb board? Your USB tutorial does not cover the modular 2.5a drivers. https://buildyourcnc.com/item/electronicsAndMotors-3axis-100-elcombo

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.

Mach 3 is compatible with our electronic combo's that include the Parallel Breakout Board.
Planet-CNC is compatible with our electronic combo's that included our USB Breakout Board.

The parallel breakout board is compatible to a wide variety of software control packages. The USB interface board that we sell can only be used with the Planet-cnc control software.

If you are concerned with your computer (desktop) not having a parallel port, one can be purchased and inserted into a PCI slot on the motherboard. Some motherboard also come with a parallel port header (connector) on the motherboard and a simple cable can be connected to this connector to get that functionality on the computer. The former solution of getting a parallel port adapter card to plug into the motherboard is probable the easiest and least expensive option.

IS THE MACH3 SOFTWARE COMPATIBLE WITH 3 AXIS MOTION CONTROL COMBO KITS? PLANET CNC MENTIONED AS BEING COMPATIBLE.

The USB controller will only work with the Planet-CNC software. This software is well made and will provide great functionality. The planet-cnc software delivers instructions to the microcontroller on the board and the microcontroller will send out the pulse trains needed to move the machine correctly.

There are two main alternatives if you want to use the mach3 software:
First, get a parallel port card and add it to your computer and get a parallel breakout board. If you have a laptop/notebook computer, this will not be possible.
Second, if you have a laptop, or really want to use the USB as the main interface for controlling the machine, you will need to get the smoothstepper board which works with mach3. The price combination is much higher than the USB controller with planet-cnc, but will work with Mach3.

The planet cnc controller can be prone to electrical interference and has been known to cause such problems. In the first instance try to use a quality double sheilded USB cable, hopefully this will fix your problem. Alternatively you may need to sheild your limit switch, estop and or motor cabling. My pick is that a quality USB cable will fix it though, worked for me.

I have your USB controller sitting here and want to control it with something other than PlanetCNC control software?

Depending on the probe that you have, you should have two wires coming from the probe. One of those two wires will need to be connect to an input pin as shown in this wiring diagram (the diagram show the probe connected to pin I4):
https://www.buildyourcnc.com/Documents/Electric%20Wiring%20Diagram.pdf

The other pin is connected to V-. Please make sure that you have 24V connected to the V- and V+ on that side of the Mach3 USB board.

The way the probe works is when the probe is in contact with an object, a specific spring mechanism will cause the input pin to be connected to the V- (close the circuit). When Mach3 senses an active low on the input pin, mach3 knows that the probe has made contact (closed the circuit).

If your probe is used as a Z-Axis zero plate, then the concept is the same, but the end mill is connected to V- and the plate is connected to the input pin. If the plate comes in contact to the end mill, then the circuit is closed and mach3 will sense an active low on the input pin.
