Re: servo vs stepper

Hi Jeff,

Thanks. I would have thought you'd need more HP or continuous torque
then that. 1700 RPM and 50 oz/in continuous torque. What feed and
rapids are you getting? If I've read the label on my daisy-wheel
printer motors correctly, I can get about 85 oz/in torque, and I think a
similar RPM. So they're STILL a possible for a Mill/Drill conversion.
Anyone interested in my Minerta servos? I'd trade for some Gecko
G320/340's!

Also I might be interested in a set of ball screws and bearings, if you
are going to offer them. I've got quite a way to go to be able to start
a retrofit. I'd like to get a set of Gecko's next.
