Wiring Diagram check

[Nr1madman]

looking at diagram in post 42 I have noticed two issues-

I would expect wiring in series a 12V fan & 12V pump across a 24V supply will damage the fan !
( pump will look like a short circuit so most of the 24V will be across the fan )

connecting a diode (FR607 ?) across each stepper driver supply fuse
will provide a path for the back EMF from the stepper motor
when a fuse blows

see revised diagram

About the diodes across the fuses for stepper drivers..
How big of a problem is it if you don't use a diod?

In my mind it's more probable that the fuse will break during acceleration instead of deceleration?

I might be wrong? :)
