Re: Sherline mill z-axis motor

This would be a build your own type of project, but this is how I would go
about it.
Get a stepper motor and one of the Sherline mounts from Dan Mauch at
Camtronics ( http://www.seanet.com/~dmauch/ ) You will find these listed at
the bottom of his products page. Then get a 1 axis chopper type stepper
driver. I don't have the link here at work, but if you remind me I will dig
up a link to a site that sells a 2 amp 1 axis chopper kit for $35.00 (Dan
M., maybe you can point me to this again. I saw it as a link in the online
version of the Seattle Robotics Society Encoder newsletter).

Than you hook the driver to an appropriate power supply and control it with
a 555 timer and a switch for direction. Total cost would be in the US$ 110 -
$150 range and if you use a dual shaft motor you can still crank the axis by
hand.
