This board needs two power sources as they claim that isolating the digital from analogue part of the board is great idea.
In short: power the board by 24V and USB connection and it will all work.
Full explanation.
In reality it might depends on what you need. if you need only to power outputs (for motor drivers) it will happily work from USB connector. All you need to do is set you limit switch Active low in Mach3 as you do not have any signal input.
If you need Inputs (no PWM no Relays) and you have only 5V you can connect them to '5V out' connection. Obviously this is not the intended use but it works fine.
The intended use is the '12V-24V Power input connection' (on image marked as 24V). Manual says 12-24 which is not the whole explanations.
If you power the board by 12V you get 5V output, power for your inputs and PWM signal. 'PWM 0-10V' terminal will be outputting 0-10V.
If you power the board by 24V you get all prevoius + the 3 Relays will work as they need 24V.
When the board is powered by USB the '5V Output power by USB' connections will have 5V. But trough these same connections the board can be powered by 5V instead the USB.
So at the end the 5V analogue output could power the 5V digital input to eliminate the USB supply for the board but you will lose the separation and that is probably not a good idea and again, not intended use of the board.
Haas designed their CNC (computer numerical control) machines with the ability to transfer program files from a USB drive to the control. This feature makes it convenient to move files between different machines or copy from a computer.
Step 1
Check if the program text is properly formatted. The program can be edited with simple text editors such as Notepad. The beginning of the file must have a '%' symbol followed by a program number starting with the letter 'O,' followed by five numbers. For example: O55555. The end of the text must be marked by a '%' symbol.
Step 2
Save the file to the USB drive with an '.nc' or '.txt' file extension. A '.txt' extension is readable by the CNC and by any other computer; an '.nc' extension is only eadable by other CNCs.
Step 3
Insert the USB drive into the port on the CNC machine. Press the 'List Prog' key on the control panel. This will display the device manager on the screen. The USB drive appears in a row of tabs across the top of the screen. Use the left/right arrows on the keypad to highlight the tab labeled 'USB.' Press 'Write/Enter' to display the contents of the USB drive.
Step 4
Use the up/down arrows on the keypad to highlight the program you want to copy. When it is highlighted on the screen, press 'Write/Enter' to select it. A check mark appears to mark the file as selected. Multiple files may be selected simultaneously.
Use the up arrow on the keypad to go back up to the tabs. Highlight the tab labeled 'Memory' and press 'Write/Enter.' The contents of the machine memory are displayed. Press 'F2' to copy the selected file into the memory. Romance of the three kingdoms 14. The file name will then appear in the list. You can now activate and run it.

Grasshopper is an incredibly capable program for creating parametric designs in Rhino. If you've ever worked with another block programming language, like Max, this works very much the same way- you can input information or geometry from your rhino file, pass it through a series of 'blocks' that each represent a different function or transformation, and output new geometry back into your Rhino file.
My Grasshopper sketch works in the following way:
1. Curves, which you drew in Rhino, are input into the sketch.
2. The number slider defines the number of subdivisions along that curve, aka, the points at which your image will be sampled. Since my lines are pretty short, I'm subdividing about 213 times (the exact number is unimportant).
3. the 'Divide' block divides your curves this number of times.
4. The points along which your lines are divided are split into two data streams- one goes into a Point Deconstructor element, which splits apart the XYZ information of every single point.
5. At the same time, the points are being fed into the image sampler. Here, you define the desired dimensions of your image in the Rhino file- use whatever dimensions you want your final product to be. The image sampler will sample at every input point.
5. The output of the image sampler is taken- we only need the new Z information. These values are multiplied by -1.
6. The original X and Y data of every single point is merged with the new Z information of the points. Now, the height of every single point is defined by the brightness of your image.
7. The points are recomposed into lines (polylines).
8. Using the Scale NU block, the new lines are compressed in the Z dimension. A little bit of math is involved here, to find out the correct scaling values- but considering the geometry of the bit you use, you can figure out the maximum cut depth of your paths before your lines start to touch. Because I'm using a 60 degree bit, and my lines in rhino are .125 inches apart, I can cut a maximum of .108 inches into the material. To be a bit more conservative I actually went with an even .100'. (original sampled values were from -1 to 1, so the necessary scale factor was .05)
9. Finally, the new geometry is moved to the top of the material stock.
