![]() The stepper motor has (not so regular) 0.9 degrees step/pulse, and combined with a 2x micro stepping driver it takes us a total of 800 steps to go a complete revolution. A rather cheap driver configured with x2 micros stepping. The circuit used in this example consists of among others: That is done on line 1 in the code below. This can easily be added to you Arduino environment using the inbuilt “Library Manager” (Tools -> manage Libraries…).Īfter this is installed all you have to do is include the AccelStepper library in your project and you get all the features written about here. It can among other thing calculate how fast the pulse train going to the stepper motors should be. It reduces things such as mechanical stresses, it can be a minimum requirement in the system, it looks and feels better, and many many more.īut how can we implement a simple thing such as ramped start and stop?ĪccelStepper is a library for Arduino that does exactly this. IntroductionĪs we have talked about: acceleration and the opposite: de-acceleration, is an important trait of every moving system. In this post will we show how a simple “stepper motor jogging-system” can be enhanced with acceleration and de-acceleration. As we have written about earlier: Jogging a stepper motor with an encoder can easily be accomplished with an Arduino. ![]()
