The Robotic Arm is finally moving! First I managed to make it work with the old electronics (based on Trinamic stepper drivers). And I also build a cheaper version of the robot electronics (Arduino + RAMPS + DRV8825 + TB6600). It looks like this version of electronics works as good as expensive electronics (only a little bit louder).
All the files necessary for the build of this robot is on GitHub. Here is the link https://github.com/SkyentificGit/SmallRobotArm
