Hi sorry if this is in the incorrect place, but i have built a Cnc machine all ali but i have a fault with the estops
the cable for the motors is all shielded but the Estops are not, they use five core telephone cable.
i think its the Earths .
i have a filter before the vfd which is plugged in to my garage socket, the vfd is out side of my control box and then the wire to the spindle which is shielded.
the motors have shielded cable but are not earthed. the top and bottom of it is i am crap at electrics and need to know what to earth and what not to earth
and where, if some one could point me in the right direction that would be a great help.
I use Estlcam Cam software
with and Arduino
