For our parallel breakout board (https://www.buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay#prettyPhoto/2/) the schematic will show the connections going from the BB to the drivers. The parallel breakout board uses the 25 pin parallel connection to communicate from the computer to drivers, and the USB is used to power the main-board itself, supplying 5V.

The electronics package I just bought from you (Book Build) is different from your wireing diagrams and video tutorials. Is there an updated wiring diagram available? Is the USB port on the breakout board connected directly to the computer USB to supply 5 volts? Thank you.

To use the inputs and outputs on the MAch3 USB controller, you will need at least a 12 VDC power supply inte 24V terminal (V+) and the DCM terminal (V-). The common lead of the limit switch will be connected to DCM (V-) and the NO (Normally Open ) lead of the limit switch will be connected to the Input of your choice (IN1 - IN4).

[65] So do you need a 24 volt power supply on the USB breakout board or can you use the 5 volt side ?

The breakout board receives 5v power from the USB. There is no need for an external 5v power adapter.

The breakout board receives 5v power from the USB port and from my computer's USB or does it need to come from a 5v adapter?

The use of the hex inverter in the application to invert a direction signal to have a motor run in the reverse directions is relatively simple.

First, go to this link and look at the chip diagram:
https://www.buildyourcnc.com/item/electronicsAndMotors-hex-inverter-breakout-newbiehack-integrated_circuits-hex-inverter

Connect 5V from the USB interface tothe VCC pin. The pin on the keyboard jog header can be used. Connect the GND pin from the USB interface to the GND pin on the hex inverter. Connect the CW terminal from the USB interface to the 1A pin on the hex inverter. Connect the 1Y pin from the hex inverter to the driver.

I got a question??? I am a dummy when it comes to cnc. I got 6040 1500kw water cold engraver 3 axis from china. I can not get anything out of them pertaining help they keep telling me the same thing over and over and over and I'm doing it and send them pictures that I know. Anyway email me a wiring diagram for the PRT 1500 watt spindle motor control box and has the emergency stop on and off switch manual PC and of course yhe screanm fultonsbusiness@gmail.com

Is there a wiring diagram for hooking up your hex inverter between your USB breakout board and the controller?

Did you connect the USB connector to the breakout board?

YES I CONNECTED THE USB TO THE BREAKOUT BOARD

I connected the electronics (for 2 x 4 feet) that I ordered from you. But how do I check if I connected all the wiring properly. There is neither any light on motor drivers nor on breakout board. And the motor shaft also does not move before and after the power supply is given.

We generally use the USB to power the interface (breakout board). The current from the computer is sufficient to supply the breakout board.

Breakout Board with Relay. What is the USB connection on this board for? Does this board Still require a 5v power supply?

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?

Most motherboard do contain parallel ports, but the port connector may not be at the back (in the section where external connectors will be connected). Instead, the motherboard may contain an LPT ribbon connector on the actual face of the motherboard (usually along one of the edges). You will need a ribbon connector to a DB25 female connector.

If your motherboard does not contain an LPT header on the motherboard, you can purchase a parallel printer adapter that plugs into one of the PCI slots. The price of the adapter is very inexpensive and sometimes is actually less costly than the actual ribbon connector.

As I am building my 20" x 24" laser engraver cutter, I notice that there is no parallel port on the onboard computer and I have the parallel breakout board any answers?

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

Hi, i have a breakout board that requires 5vdc and i need a power supply for this. What amp rating power supply do i need to power the breakout board without frying it?

The 5V power required for the breakout board can be a simple USB male to male cable, that will connect from your computer to the board itself.
Now adding a external power supply make sure that it does not exceed a total of 5V and the standard 500 MilliAMP - 1 A.

I have a YDH-18-5 Power Supply AC Input:100-240v 47-63Hz, Ouput: 5v - 2A and need to know if its safe to use with the Parallel Breakout Board.

The digital signal portion of the CO2 laser tube power supply has various terminals for signal power, signal gnd, laser intensity and engaging the laser (turning it on or off). The TL and TH are triggers to turn the laser power on or off. These may be labeled L or H on some laser power supplies. You can use either TL/L, or TH/H to control the laser.

If you use the TL or L terminal to control the laser:
If a low signal (gnd) is present at that terminal, the laser will turn on. If a high signal (5v) is present, the laser will turn off.

If you use the TH or H terminal to control the laser:
If a high signal (5v) is present at that terminal, the laser will turn on. If a low signal (gnd) is present, the laser will turn off.

You should first test the control signal from the interface with a multimeter to make sure the laser will be controlled correctly before powering the laser power supply

On the blacktooth machine wiring diagram for parallel breakout a wire goes from 6 on the BOB to TL on the laser power supply. My power supply has an"H" followed by a "L". Which is correct? I've connected to the "L" but the laser appears always on.

What part of your breakout board is not working? Are you having trouble getting a signal from the computer out of the breakout board to the drivers?

The breakout board uses the USB as the 5v power source.

can't get breakout board with relay working. in your video you show a 5v power supply input on the usb one but can't not find on this one?

No, we have gotten away from the planet-cnc boards as they have decided to not support our board with their software. You can use the Mach3 USB board as an alternative. You will be better off with Mach3 as a control software as this is widely used and supported.

I have the older discontinued USB breakout board. The y-axis no longer works and have traced it to the breakout board. Is there a replacement board that can use the same Planet CNC software running on Windows 10?

A parallel breakout board requires a computer with a parallel port. The parallel port provides the communication. The reason the board has a USB port is only to provide power to the board from the computer. If the USB connection is not plugged in to the board, the board will not have the power needed to function correctly.

the breakout board that i recieved has both a 25pin and usb connections. can i use the usb to plug into my laptop

First, you should check the configuration in your CNC control software and determine if the spindle control pin is correctly set. That pin will engage the relay.

The P and O position of the relay is set as Normally Open where the relay is open (open circuit, or no connection) at idle and when engaged will be closed (closed circuit, or connected). If you suspect that the relay is damaged, the recommended action would be to disconnect the spindle from the relay and operate the spindle/VFD manually using the Run and Stop buttons on the face of the VFD (until the breakout board can be replaced).

The spindle has started on my Machine while the machine was sitting idol, I'm not sure if the relay has failed on the breakout board. Is there a way to test this?

What we intend our customers to use for wiring the motors to the drivers will be 4 conductor 20 AWG cable, now for the PSU to Drivers; 16-18 Gauge wire should be used, and drivers to BB(Breakout Board) should be a 24 AWG wires.

The mapping of the input pins of the parallel breakout board is configured through software. The input pin are very versatile and can be mapped to all kinds of different types of input including axis limits and axis homing.
