A power feed with 6 well defined feed rates for my Proxxon FF500 mill. Unlike many solutions on Internet (mostly with a wiper motor), this is a direct driven stepper motor solution (no clutch or gears needed) with fixed speed rates ranging from 1 revolution in 100 seconds to 3 per second. A very simple NE555 based circuit provides the needed square waves for this small (6*10*12 cm) device.
If you have any questions about operation or implementation details: Don't hesitate!
Music: Bach, Beethoven, Grieg, Mozart, Albinoni, all public domain
