Re: dinky microstepping driver ? Linistepper

Dave,

Romans honesty in specs might be misread from your post...

Very few microstepping drives are actually accurate at each step.
Roman is just saying this. His drive is no less precise in its steps
than most any other microstepping drive... In fact, it can be tuned
to be more precise to a specific motor if you can "do" pic
programming.

And the 3600 IS based on a std. 1.8 degree motor and its 200 full
steps/rev. So yes, up to 3600 microsteps per rev.

BTW, The Xylotex bd is also 35 volts, and so is the 5804 unipolar
chip. Until the recent Gecko debut, 24 and 35 volt stepper drives
were really common. Still are... I've run 297/298 drives at 34 volts
for years... Plenty of torque, since torque is amps, not volts. And
Jeff can speak to the speed available at 24 volts with his Xylotex
bds...

And while we're talking volts, be sure to read what Roman has to say
about the subject in his description/ tutorial. When I first saw
these about 6 or so months ago (and ordered a few), I was thankful
that someone was saying something besides "Ya gotta run at 10-25
times the motor rating..." Different drives perform differently, and
to try to use the specs/recommendations for one to evaluate another
can be a bad choice. The proof is in whether the needs of the
application get met.

25 bucks and some solder time instead of hundreds? Not a bad trade,
IMO. And these drives, as I posted already, are pretty nice. And
cheap. Just hot.

Hope this helps,

Ballendo
