I have a CNC mill with DC brushed servos controlled by an 1880 Galil card...
It is an old machine that has worked well for a great many years. I recently moved it 2000 miles. Just powered it up today. The Y axis will vibrate at the stop position. Move it and it may be fine or it may vibrate again. Put your hand on the servo and its rotating back and forth rapidly just a half degree or so.
What should i do to correct this?
