leonhuynh2006 Hi all pro, I am new in CNC. I have connected mega + ramps + tb6600 as enclosed photo. I used grbl 1.1 mega 2560 version, selected the right port (COM 3), the right board (mega 2550) in Arduino IDE. Uploading firmware was ok. But when I tried to test it by using Universal GCode Sender manually, but the motor didn't spin Did I miss out something. Pls helpppppp Thanks
