I have been reading threads to figure out what I need to know to hook up a G540 and all the gear . I saw one drawing that had relays on it . What is the reason for a relay and a coil ? Heres where I saw the drawing .
48V 20A Panel Mount Relay [RL-04] - US$8.50 : Homann Designs, The Preferred CNC Component supplier
Also there is talk on limit switches and home switches . I would like to use the same switches for both . Can I do this with the G540 ? Anybody have some good drawings on wiring these up . If I have to have separate switches for limit and home a good drawing of that or a link to a good thread would be great .
Thanks , Mike
