I bought a preloaded grbl ATMega328p chip for my arduino. I made sure I put it in the right way so then I hooked it up to the computer. I opened up serial monitor and went through all the baud rates but I keep getting a bunch of little squares. My question is did I do something wrong or what should I do.
check out http://www.arduino.cc/en/Guide/Troubleshooting#upload
and then try a search or a post in Installation & Troubleshooting forum

Thank you for the suggestion but that's not the problem I'm having so it doesn't help but thank you.
What is "grbl"? I've not seen that before. Where did you get it from?
"Grbl is a free, open source, high performance CNC milling controller written in optimized C that will run on a straight Arduino."

Basically what it allows you to do is use G-code with your arduino for your project whether it would be a CNC milling machine, 3D printer, or anything you want it for. The reason why I picked it is because it looked simple enough and uses arduino and also is inexpensive.
