ok. i cut the power to the drivers, and changed to 1600 (on, off, on, on), and tried again, and now it moved half the distance, example move 50, and it did 25, and mach 3 set it to 320. typing in mdi the same thing, it moves the right distance typed in but somewhat faster.

in motor turning, the "steps per" is set by this test, velocity 600 mm per minute, acceleration 50, G's 0.0050988, step pulse, dir pulse both to 0
