Mock up of track mounts. This went through 3 changes before i was happy. Now i cut my first aluminum pieces. Jigsaw and drill press. 1/4" aluminum sheet i had laying around. Should have enough to do other side and base plate of robot.

track assembly test 2. Modified the brackets and moved the wheels around for better clearance. The blue squares are there so i can print to size A paper and align front and back pieces together. then i can glue to aluminum and cut out the shape with wheel alignment.

SerialStepperController.ino

Serial communication code for arduino mega and RAMPS board. I had this hardware laying around. Code is setup for a serial control. Send < x,y > can be -1000 to 1000 steps per second. using 0.9 degree step motor. X is my left and y is my right motor. May modify for 3 more steppers later. as ramps can handle 5 steppers
