OK, need someone to give me a Y/N on stepper motor:
I'm looking at
[proto-pic.co.uk]
and according to wiki (http://reprap.org/wiki/Stepper_motor) this seems to have enough holding torque for the 3D printer kind of work
"But we need to know exactly what you are planning!"
yeah... that would probably help me too
What I'm doing is, Making Anything That Sort Of Works. I have bits like picAxe and Pi and generally "stuff" around to work with.
I picked up some threaded rods and studding connectors in Wickes yesterday, if I can get to the point where I make those move about a bit and attach boards to them, it will be a huge learning step for me.
How I see myself progressing:
1. Make a motor turn a rod.
2. Make the motor move under computer control.
3. Make 2 motors move in a synchronized way and end up with a flat bed moving according to pattern.
3a. Put a felt tip pen in a gripper on some paper stuck to flat bed, draw a picture. Win nobel prize.
4. Add a third axis to fix tools to do actual jobs, up to limit of current mechanics.
5. Start again knowing what I will understand at that point
So, is the motor I was looking at roughly the sort of thing which might let me do this, or am I miles out?
