I am new to this Forum as well as to Arduino and CNC machines.
I have a problem with my newly built CNC plotter machine. I tried to send a gcode text graphic (created with Inkscape) to Arduino Nano board using GRBL controller software. But when I hit the open button I get a message “No data from COM port after connecting. Expecting Grbl version string.”
I selected the correct serial port and baud rate as 9600.
Could someone help me in this regard please. I am really desperated. Please ask me if you need any further information regarding this issue.
