I will be posting the steps in detail once is start from scratch with this new one and verify the process works flawlessly. The first one is working correctly now!
Good evening Karl, I finally figured it out, but to answer your question once you zero out the position let's say North, then save it to the eeprom on the Arduino then when the power is restored it automatically goes to the zero position even if you manually change it by hand. My problem was there's and extra step to making sure the rotation is correct and its something due to the number of steps set in the beginning.
Hi Louis, how does the stepper motor know its position? Have you got that far yet? I keep thinking every time you turn off power, it will lose where it was? I managed to by a hole box of these, but never got around to them yet.
Great work Louis, and looking forward to seeing it finished and working.
cheers, John
