Planet CNC has the option to turn off these outputs on your USB board. Under the File/settings/Pins. You will have Spindle (M3,M4,M5) Coolant (M7,M8,M9) as available output pins. On the drop down tabs for these output pins you will have this option ( --- ), if selected it will turn of that output pin in your board and you will get not voltage change in the pin.

On the USB controller I am unable to get voltage from the Mist relay block on the board. The Flood and Spindle produce a voltage change correctly. Is there a setting I am missing?

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.

To control a spindle using the USB CNC interface, you will need a relay board that contains a transistor that can activate the relay with a power source with enough current that can activate the relay. This video explains all of the information you will need to develop this relay circuit:

i have a breakout usb controller iam using a spindle output to active a relay 5V but it didnt work.... whats the problem, what else i need to active that realy 5v 10A?

Yes, you can use a corner plate very easily. You will want to make a corner plate that has three independent plates that do not conduct with each other. Each of these plates will be connected to a different input (i.e. IN1 for X, IN2 for Y and IN3 for Z). The end mill or tool that is inserted into the spindle will connect to V- of the 24V power supply, or the DCM on the controller, which is connected to the 24V V-. Then, you can use the ref all home button on the program run screen of Mach3.

Is there a way to use an X,Y plate that will only be responsible for corner finding in Mach3 with the Mach3 USB controller?

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:

Do you sell the 3 axis electronics combo , for heavy gantry , with the new Planet CNC usb controller ?

That will depend on the controller that was installed in the redFly. If the controller is a pokeys57CNC controller, you can use Mach 4 with that system.

You can add a 4th axis and an ATC (Automatic Tool Changer) with the redFly system.

Does the Redfly that I bought with the GreenBull in 2016 work with Mach4? Also I want to add a 4th axis and a spindle with automatic tool changer. Will this work too or do I need a new control board? I bought my CNC with a longer Z travel, so I have plenty of room for these. Thanks!

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.

Mach3 doesn't take MPG input from USB RnRMotion board. While running Mach3 "Manage plugins">"RnRMtion control panel. I can see the signals from the hand controller changing, Mach3 diagnostics show nothing. Motors are controlable when i run G-code.

We could not guarantee, nor say, whether or not your current software would be able to utilize the USB breakout board. Our USB breakout board is designed for use with Planet CNC software found here, http://www.planet-cnc.com/index.php?page=software

As far as we know, this is the only CNC Controller software that operates on a USB breakout controller.

Is it possible to manage USB Controller (Breakout) from my own (custom) Windows application? Is there a driver API or smth for that?

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.

The PlanetCNC USB software, like most machine control software, can be used to control a laser engraver/cutter. The typical modification is to use the Z axis down signal to fire the laser, analogous to an endmill cutting into the workpiece from an initial position above it.

For the second question, it is important to note that BYCNC machines are not based on PlanetCNC software, or any other particular machine control system. The machines themselves will accept standard signals from a wide variety of machine control systems, not just PlanetCNC or Mach3. This allows maximum flexibility for the customer to choose their own preferred software for this part of the toolchain.

That said, our machines will accept a laser head either in lieu of or in addition to a spindle. Here is an example of a combination spindle/laser mount for our greenBull machine: https://buildyourcnc.com/item/cnc-machine-laser-spindle-combo-head. We have all the parts you would need to add laser functionality to your machine here: https://buildyourcnc.com/LaserComponents.aspx, if you feel comfortable assembling your own package. Also, feel free to contact our sales department for a quote if you need a custom assembly.

Can the Planet CNC USB controller be used with a laser engraver/cutter? Can the build your own CNC based on the Planet CNC USB controller accept a Laser head instead of a router?

We are currently working on a relay board that will connect to USB breakout board, and the router/spindle for both the on/off function. Unfortunately we still do not have it completed or ready to be placed on our website, but it is in the final stages of testing. Please check back regularly for updated stock!

I AM PUTTING TOGETHER THE BLACKFOOT AND USING A PORTER CABLE ROUTER. CONFUSED ON HOW TO RELAY ROUTETR WITH USB BOARD. IS THERE ANOTHER SWITCH THAT GOES BETWEEN BOARD ROUTER SO PLANET CNC CAN TURN PERHAPS VACUUM OFF?

Do you have the Pokeys57CNC connected to a 24V external power supply?

Additional Information:
Yes, a 24V external power supply with the jumper positioned. I'm using the ethernet port so the 24v is the only source of power. I plan to measure the amp draw when I have a chance to see how much the vfd is drawing on the analog out.

Additional Information:
Further information. The resistance across the terminals on the vfd is 22k ohms. With an independent 0-10v current source I can run the spindle from 20 to 400 Hz. The PokeysCNC only gets to 3.8v with the vfd attached (and the vfd is at 150 Hz) compared to 10v when the vfd is not attached. The power to the PokeysCNC is steady at 24.18 V, so I'm not maxing out the power supply. Still looking for thoughts on what might be going on?

Additional Information:
And the other thing - The measured amperage is 0.17 mA for the 0-10 V signal (which makes perfect sense for 3.7 V and 22k Ohms).

Additional Information:
Just to bring finality to this issue - I added a 2.2 microfarad capacitor across the 0-10V input terminal (from signal to ground). This solved the issue. Evidently, it was an electrical noise issue.

Click the link to add information to this solution:
My pokeysCNC board creates and analog signal of 0-10V for 0 to 24000 spindle rpm just like it should from Mach3. However, when the spindle is on, the voltage only gets to about 3.8V for 24000 rpm. It seems like the vfd is drawing more current than the pokeyscnc analog output can produce. It there an easy solution to this problem?

The diagram for wiring the USB interface board is located here: https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/

Under the board illustration, there are three smaller diagrams of limit switch wiring. On each, there are two connections, the GND and the pin which are labeled at the ends of the circuit on the diagrams. The pin side would go to the axis label ++ or -- terminal (i.e. X++, or X--). The other end, labeled GND would connect to any ground terminal on the board.

I am using 5 limit switches on my 3 axis machine. I am using the usb controller for planet cnc. I would like to know where all the wires related to the limit switches get connected? A diagram would be helpful.

The USB interface only works with momentary switches unfortunately. If you have extensive knowledge of digital electronics, you can apply a receiver that uses a microcontroller and a transmitter with another microcontroller that produces the pulsing signal with the controls that you need.
