Hi, bought a spindle from Amazon because I bought one from ebay and then a week passed and then they refunded me the money so I paid the extra to get next day. Seems a lot better quality than the last spindle, better sockets, weighs 1kg moor and feels better machined,
They sent me this message
The only thing I already probed the 4 pins and there is continuity between pin 4 and the body so I cracked the aviation plug off and this has a proper GX25 on it rather than the custom 20mm they normally have and low and behold there's an earth wire connected to pin 4 going into the spindle body somewhere I couldn't see where
pins 1, 2, & 3 have no continuity to the body only to each other
So it's actually grounded even though they emailed specifically to tell me it's not, right?
And I should connect pin 4 to earth?http://www.mycncuk.com/threads/10880...60cm-work-area My first CNC build WIP 120cm*80cm
If you didn't buy it from China the company you bought it from did ;)

Of course, it's a safety thing. The metal case should be connected to the protective earth (PE) and not to ground, which is normally the DC common. Same as your iron which you use for ironing your shirts with.

You've purchased it finally from Amazon and returned that one from eBay? Did I get it right? I mean, you're satisfied with the Rattmotor from Amazon?
