to be the case with steppers. I'm wondering why anyone would opt to
use them. The drives are much more expensive, alot more difficult to
configure. Heating problems compared to servos etc. I've just noticed
alot of posts with questions regarding steppers and I'm just confused
why anyone would use them. There seems to be an abundance of used
servos around. One person one here mentioned that "the steppers on
his small mini-lathe produced enough heat to fry eggs"

Becasue steppers are so dang easy to use.

Also, because most people do not know where the 'abundance or
servo's' are and/or don't want to get involved with encoders as there
are not a lot of cheap encoders around.

Steppers offer the power at cutting speeds so in that way, are ideal
for home-brew.

Stepper drivers are easy to make, find or buy.

There are a few complete stepper packages for small machines that
sell for under $200.00

I don't know of any servo packages that are that low cost.
