I appreciate the insight but it's getting away from what I originally posted about which is calculating the torque required for a load to move with a desired max acceleration and top speed. You are explaining the nuances of driver controls which do have an effect on the current/torque but the vast majority of the calculation I ran and am here trying to verify the logic behind, are not being covered. Knowing the moving mass, top speed, top acceleration and the capabilities of the micro controller to send pulses should be enough to figure out roughly how much torque is required from a motor. I don't like throwing money at things and hoping they work, I actually like to know how and why they work so I can manipulate them to suit my needs. Sorry, I'm just starting to feel that the level of detail with this one particular part is making it so I can't see the trees for the forest.
