I have recently tried to hook up my motors to my RAMPS 1.4 board, but was confronted with the problem of the motors vibrating instead of turning. At the time, I was using Sprinter. I have recently...

I've calculated the the proper steps per mm and still produced the same problem. I've also blindly chosen larger and smaller numbers to see if they had any effect on the steps and they did not. I've...
