Crazy confusing stuff, isn't it? Stepping aside (badum bum!) from bipolar vs unipolar, there's all the other good stuff needed to optimize stepper performance. Microstepping was mentioned (but can I rely on it for more accuracy--no probably not), power supply (you mean I want 20x the rated voltage, come again, that can't be right?), parallel vs serial windings on an 8 wire motor, yada yada yada.
Now add to that the other crazy confusing discussions we have over and over again:
- Should I use steppers or servos? Whoa, all that stepper stuff seems simple compared to servos, but the real pros use servos, but can I afford them????
- What kind of leadscrews? ( aka Why can't my acme screws be made to perform as well as expensive ground ballscrews? )
- What kind of angular contact bearings should I use and how do I mount them? ( aka, I just want to use $7 skate bearings but NC Cams will kill me if I do )
And that all time favorite, "I just bought a drill press at Harbor Freight and wanted to share my plans to make it perform as well as a Haas vertical mill."
Simpler questions include, "I just bought this really cool on freeBay for a song. I want to base my entire machine around this one piece. How do I get all the other pieces to make it work just as cheaply?"
But you know, that's what makes it fun. There is so much to learn, and something new pops up every single day.
Best,
