Programming a stepper to have a "home" position?

Asked by Jonathan_hodgkins (690points) December 6th, 2017

I am trying to program a stepper to rotate a certain angle and speed around a fixed point, everytime. However, when the power goes out, the program restarts and it’s location is lost. Any idea how I can get the stepper to remember to start at a certain location or remember it’s location within the arc?
