hi,
I hope someone can help me with my mach3... I've bought new breakout board and trying to connect with mach3, I already change the port address to my mach3 but when I load G-Code it not even move. how should I know that breakout board is connected to mach3?

Can you provide details (make, model, etc.) of your Breakout board and your CNC controller.

Also which PC operating system are you using ?

Tweakie.
