re; because it look like it is to complicated
Yes, they are more complicated. but they have capabilities far beyond a simple primitive step driver. every added function on a pokeys device is a HUGE advantage to a hobby CNC builder. the LCD screens, the DOZEN of outputs , the block programming language , the ic2 interface, PWM outs, these are worth spending time to learn. the more i learn the more i respect the designers . i have 'spent' 1000s of hours over 6 years, and I am amazed at what I can do with these.
ok back to work . .
