When the editor is active, the Mach3 interface changes into a design canvas. You will see a toolbar usually on the left or top side with the following key elements: To customize your Mach3 interface, you can use

DRO (Digital Readout): Displays numbers (coordinates, feed rate, spindle speed).
Button: Clickable objects that trigger actions.
LED: Status lights (Green/Red circles) indicating if a function is active (e.g., Spindle On, E-Stop).
Label: Static text used for headings.
Bitmap: Images or background graphics.

DoOEMButton(100) – Trigger an internal function

Pro Tip: Do not delete the original script unless you fully understand it. Copy it to Notepad first as a backup.

Understanding the Properties Panel

When you click on any element (say, the "Cycle Start" button), the right side of the editor shows its properties:

X/Y Position: Pixel coordinates.
Width/Height: Size in pixels.
Font & Color: Change the button text and background.
Button Action: This is the magic. This field contains the code or function call that executes when pressed.

Navigate to your Mach3 folder (e.g., C:\Mach3)
Run Screen4.exe (not Mach3Loader.exe)
File → Open Screen → select a .set file (e.g., Mach3Mill.set)

💡 Tip: Copy the original .set file first and rename it (e.g., MyCustom.set) to avoid corrupting the default.
