Re: [CAD_CAM_EDM_DRO] steppers or servo?

One reason people use closed loop servo system is because
it does not loose it's position. A good stepper-servo theory
source is listed below,

www. linuxcnc.org

and look under the Compumotor link.

Hi,
Computer printers use stepper motors and they run forever with
incredible accuracy. A hobby nc machine will also have the same
repeatability as long the motors are not forced into missed steps,
right?
Servos can also be forced into missed steps so the advantage over
steppers must just be the extra speed to return to the home
position?
