I have the following stepper coming soon and need a power supply. I am planning on using an a4988 controller. I have read several articles and forum posts but steppers seem to confuse me about their power supply. The stepper will be turning a table, it will be direct drive and have about 4 pounds in it at anytime. It will only be turning 1/6 of a turn at a time and needs to do that in about a second. Based on what I have read, the more voltage the better with the controllers range. So, I am thinking of a 24volt 1amp supply. Can anyone add some reassurance that this would be a good choice?
