Setting Sprinter with Ramp 1.4

1. Arduino 2.3 to upload Sprinter to Ramp

   change config tab

   float axis_steps_per_unit[] = {80, 80, 3200/1.25,700};

2 The Z axis setting

   a 200 step motor using 16x micro-stepping gives you 3200 steps, an M8 threaded rod is 1.25mm per complete revolution so 3200/1.25 = 2560,so my gear ratio is 2.5,I must set 2560X2.5=6400 for 1 mm up or down.

float axis_steps_per_unit[] = {80, 80, 6400,700};
