The drawing is a bit ambiguous for me I would prefer more of a schematic. Do you really need 4 PSU 2 x 24 V 1 x 9v and 1 x 12V.


I don't know how big your machine is but its a shame to use only 24V psu and those drivers because your machine might have so much more potential if they were changed.
I have bumped this up so that Dean might see it and chime in. Clive
