Gentlefolk, Thanks for all the comments and suggestions.
Back looking at the basics. How do I know the motor is 50 steps/rev??? The motor is an Epson EM-257 which I have not been able to find much about on the Internet. I held the shaft of the motor and rotated it carefully. 50 "steps" (harder movements) per rev. Originally the thing seemed to go beserk when run at 200 steps/rev. But this may have been effected by my early settings, excess current, velocity, etc. I have just set the steps/rev to 200 and am now starting to fiddle current, velocity, etc. Looks encouraging. So how do I determine the number of steps per rev accurately??
