One thing I do notice once in awhile, if servos are on and machine is idle for several minutes, usually Y1 starts to vibrate ever so slightly, enough to make noise. If I jog the gantry back a touch it goes away.
The other strange thing that has started happening lately is if I turn the magnetic disconnect for the plasma/ drives off (smaller one ahead of that for the computer stuff etc), sometimes the phase perfect shuts down. I have the dp20 setup with a light switch to turn it on/off and I have to go over and flip the switch off and back on again. No fault light in the DP20, just the normal green led.
The Dmm tech is recommending I just pull the 3rd leg from the servo drives and be done with any issues from the 3rd leg.
