The last stepgen worked! However the noise is still messing things up. I pulled the cover off the z axis so I could see the screw, and there is just enough noise getting into stuff that at any step timing up to 2x whats normal for a 2m542 driver, it fails to return to physical zero. It does according to my readout in lcnc's dro's, but not on my dial indicators. Its 3-7 thou per movement command, fairly random. FWIW, the M542T driver does need at least .2 microseconds wider a pulse to do even that well. AND the timing and current settings painted on it do not match the charts on the 2M542's either. Throw in that in order for it to read the dip switches when you change them, you must unplug it from its power supply and its power input pins crowbared for 10 seconds. It has an excellent memory. I can hear it stumbling too. So I have both axis's moving, but I've still got noise problems. So I guess I am waiting now for the beads now. I think its best for my health and well being, If I see what I can drag out, or go get for some din-din. > > Peter Wallace > > Mesa Electronics > > > > > > -------------------------------------------------------------------- > >-- -------- Developer Access Program for Intel Xeon Phi Processors > > Access to Intel Xeon Phi processor-based developer platforms.
