I had a look at this presentation and it covers all the basics.
The key is understanding that you generaly need to accelerate from some minimum step rate up to the desired step rate then decelerate down to the minimum step rate then stop. Your motor characteristecs along with the load characteristics will tell you what the minimum step rate is and also the maximum step rate you can achieve. Onece you have these figures you can use the step/delay technique but you have to vary the delay to achieve the acceleration and deceleration. Whenever you want to change the speed of the stepper you need to go through and acceleration or dceleratiion phase. HTH Ian |
