Hi Rick
That looks great many thanks, IYHO what would be the best way to divide the 240 supply, my thoughts are a 240 volt busbar in the cabinet, with a tap off to the Mill and a tap off to the rest of the cabinet.

Or perhaps you could use a switched fused spur to feed a double sockect
Ray I wouldn't put the Mill spindle and the Control box on the same fuse.? If the spindle bogs down and just happens to draw a bit more power when the steppers are working hard then the combination of control box and spindle could trip the fuse. Where's on there own fuse's the Mill spindle will handle the Bog and continue without affecting the control box.
If you want true safety use a relay system to shut the other down. This way both protect each other in case of failure or power loss and the relay in control box will stop the spindle if it goes offline and vise versa the spindle relay will inform the Control box it's failed which will then stop things in a controlled manner turning off or killing power to other important attachments and halting Mach3.
You can also control the spindle ON/OFF thru Mach3 and G-code in a similar way.
Hi, many thanks for all the advise, it's now getting heavy (I am a retired Mechanical engineer) but i do not give up easily, forgive me a few more questions.
Hi Jazz, what is a Bog ?
Would a drawing of a relay schematic be possible from anyone, as I read drawings ok, sometime the written / verbal passes me by.

I know this is a simple take on things but here is a circuit that does the job..

If anyone has a better circuit post it up so we can help this chap out LOL
Rick
Hi Rick, are the latching switches just for lamp indication, if yes can i get rid of them, don't want to make it to complicated yet.
Regards
Ray
the switches do have lamps in them but they are not required, the switches are there to latch the relay on so when power is lost to either relay it unlatches and stops the other supply, like an interlock circuit one is dependant on the other.
The switches i have used are on off two button switches one NO and one NC, the NO switch gives power activating the relay and hence giving power through its contacts to itself and the NC switch is used to break the circuit de-energising the relay.
Attachment 7907
You could of course use two seperate switches per relay one momentry NOand one momentry NC. Im just lazy and opted for the one with a light in it... (i like lights!!.. before someone else chimes in)..
Rick
if your on a tight budget let me know and ill post over a couple of switches without lights FOC..
