Printer stepper motors

[Christian Knuell]

Hi,

Servo motors are very difficult to control. They need special, often quite expensive controllers and can be a real pain to set up properly.
I also wouldn't rely on old printer steppers too much. They are designed for relatively high speeds but have very low torque. Everything needs to run absolutely smooth or you'll loose steps.

Thank you for your advice, in particular your comments on the printer stepper motors. I have just been looking at a web site called allmotion who are offering controllers for both stepper and servo motors.
