Thanks for the link but fired off another email to China, searched high and low and can't find the ones I bought ? but thinking about it now I might not have ordered them after all.

Still need the reversed sockets to the ones shown, it's illegal to use these on commercial equipment at greater than 30 v DC

I know it doesn't really apply as XY and Z are always connected but the A axis is mainly left unconnected and any stray chips can easily short the drivers out.

Remember I'm working on commercial metal cutting equipment and need to follow wiring regs.
