Can you help! I Cannot get my controller to run my motors on my root 3 lite. I have downloaded the marlin software in git hub and I verified and uploaded it to the Arduino. When I plug the Nemma 17 motor into the Ramps board and try to run it with pronterface nothing happens at all. unfortunately I know nothing about electronics and programming so I don’t know how to troubleshoot this. hope you can help.
