That leads to a different driver, one I've never seen advertised yet, which reads as if it may be "next generation" software in it, says auto tune, which the MA860 has none of. Its also, about $132, 2x the MA860. What I just ordered may be better, and since I ordered a dual shaft motor, I can put a damper on it. At 4.4 mh connected bipolar-parallel, compared to the 23mh of this one, it ought to fairly scream for rapids once I get the counterweight springs sorted. > Le 20.04.2016 06:33, Gene Heskett a écrit : > > Greetings; > > > > One of the things I am noticing, when running this crippled Z drive > > at various speeds, is that up to about 3/4 rps at its shaft, it > > moves dead silently, but by 2 rps, its rattling tools off the table, > > exactly as if is was being full stepped, and it doesn't become at > > all smooth again until its moving the head at 25 ipm or more, then > > stalls at just under 48 ipm. > > > > 2 related questions then; > > > > This is a DM860 drive.
