I was having the same difficulties as magicwiu. This thread seems to almost answer. When you say it only sends “Ok” or “error” after each command. Where does it send this to. Shoulld I see “Ok” in serial console ( I am using minicom ). After I connect to grbl on Arduino I get:
Grbl 0.6b
‘$’ to dump current settings
When I type $ and hit Enter nothing seems to happen.
I am connecting to Grbl on /dev/ttyUSB0
I am using Arduino Duemilanove with Atmega328P
Thanks in advance
