Hitec D845WP Servos Can't Move Slow And Smooth

I'm testing a new robot , using ezbv4 and hitec D845WP servos with lipo 7,4 V batteries. (I never used these servos and such high-current batteries before). These servos are very quick, expecially with lipo batteries. So, when I program an action, I can't get a smooth and and slow movement, no matter how  I set delay, step and speed in the action  window editing area.  I can't get a continuous movement. The servos are so  fast, that they perform, with any setting , only a series of very fast and precise steps. Indeed, they follow exactly the staircase generated by ezb. I can  get a continuous movement only by  clicking  "transition to" , from a frame to another , in the Auto Position screen, with a speed =50. But in the action window editing area I can't set  a speed  of 50, but  only  a maximum of 20. What can I do ???

Ah, Rome! One of the cradles of our civilisation in my uninformed opinion. I hope to visit some day.

Anyway, understanding the Delay, Step and Speeds were a challenge to me also. I feel your pain. I'm sure with a little practice and testing you'll come to understand how to set these primeritors and get your servos running smooth.

I'd also suggest that you go back into the HiTec software and set them back to the default settings. Let ARC control them completely.
