[Swansea Hackspace] Bits for 3D printing

[Tim Moore]

Silly question using 3D technology:-

I've got a Stepper motor which chuggs round in 1.8 degree steps and I need
it to go through 180 degrees in approx 40 seconds....

but the rub is its needs to be smooth, and it does an instant step.

Any thoughts on a motor that can drive a 1/4 inch aka 6mm spindle smoothly
under precise speed control ?

Its currently attached to an Arduino UNO.

Many thanks to anyone whose got any thoughts on this....  is a learning
curve for me.....

:  )))
