I'm using a 1.5kw chinese spindle. I have it grounded to earth but it would be nice for it to be permanently connected to 0v DC so I don't need to put a clip on the bit every time I want to do a Z probe. Any comments on if this will cause me problems? Obviously it can be okay for short term because it happens every time you connect the clip for probing, but what if I just hooked 0v DC to the same wire as the earth ground?
