Re: Power Supply NEG returns questions
There are two schools of thought on earth grounding DC power supplies, for example your P.C. P.S. common is connected to earth ground.
Many systems and myself included prefer to earth ground all power supplies to the common service star ground point.
Ensure motor frames such as spindle etc are equi-potential bonded to the star point.
