Hope I am doing this right! Yup I am a newbe! But I am really familiar with cnc. (retired cnc machinest) I have an Arduino uno r3 and using arduino ide to flash grbl. Looking at the install through the IDE seems to show that it was a successful install. But when I go to universal g code sender and select open I get the following line repeated endlessly down the window. Baud rate is 115200 and com port is correct. [verbose]<Idle,MPos:0.000,0.000,0.000,WPos:0.000,0.000,0.000> I have not plugged stepper drivers into the arduino yet. I wanted to check the settings in grbl 1st. But when I type $$ nothing happens except the verbose line above continues. I have one of my steppers and drivers ready but before I buy the rest I wanted to check to see if everything was right 1st.
