The given parameters--motors, drivers, switches . . .
More known variables: wiring diagrams and equipment dimensions.
Sketches beginning to quantify and give form to the requirements.
Right & Far Right: : limit switches and wire lengths
Right: motor wiring lengths and conduit sizes, lengths & components, communication wiring lengths & locations.
Far Right: main power supply cabling, plug, location, switch, routing concepts for main circuit groups.
Right: Spindle power and control wiring
Far Right: control cabinet layout sketches & requirements.
Right: motor and component power circuit layout concepts & cabinet organization with wattage to balance system.
Far Right: power layouts & sizing. Note the note "P.O. Brake" for the Z axis "Power-Off Brake" component. This keeps the Z axis from falling when the power is turned off.
From here we can start laying out the control cabinet pieces and making the mounting plates for the various components which we'll get into in the next Build Log 09.
