I'm doing another CNC conversion - my largest yet. G0704 (BF20) style mill,

maybe my next machine will be servo)

Hi,
leadshine is a china brand of good quality stepper driver
(automationlogic seem to be leadshine model DM856 for example, there is
a lot of re-branding within leadshine drives)
I like the digital version (DM series, you can tune out some resonance,
work well). I don't know much about the

I just don't believe in trying to trim the size or power of a stepper to save
a few pounds/dollars. I'd rather over-spec slightly in the knowledge that I
have power in hand.
It isn't necessarily that simple,

Thanks for the feedback and the link.
I logged back on to say that I had purchased some of those DM856
controllers, enough for my 4 axis mill build, plus one spare, just in case.
I do have a larger lathe that I'm trying to get myself to CNC - an Emco

John,
If I can get the shop straightened up a bit in
the next couple of days I will try to show a

Hi Gene;
No, my little Unimat is really just for show. I take it to exhibitions,
and it moves around, but does not cut anything.
