Wagner:

I've playing too with laser reflected in mirror attached to stepper motors,
trying to make simple figures in a wall.
But my major problem was that the motors (small steppers from an EPSON matrix
printer)didn«t run the fast enough I needed.

What steppers have You used for it?
What is galgo? A type of servomotor?

Thank You, and please excuse my bad English.
