HELP! Two duet wifi + two duex5 for two print heads?

Here is a drawing of what I'm thinking.

I will use two systems like the picture. That's why I need 14 heater cartridges. It is important to me to say that the machine is intended to print with a 4mm nozzle diameter and the material that will be used is ABS, that's why I need a long and hot way for the filament to melt and let me print at high speeds. What do you think? Any help?

Suggest you contact E3D and ask their opinion on what you propose.

As Ian says e3d will have a better idea about this.
You may find that having only two preheat zones rather than three per input is acceptable. Also why complicate it with the cyclops? is that to get a higher flow rate? better to use a larger single extruder. with a 4mm nozzle you are printing thicker than the input filament (3mm or 1.75mm) so designs to look at could be pellet extruders / filament extruders like filastruder:
-
I could see all 7 heaters being controlled off of one mofset or DC/DC SSR.

Yes I though that but which thermistor do you monitor? Or to put it another way, where in all that do you measure the temperature? What happens if the filament gets melted in the first heater block? - the other heater blocks then becomes redundant. What happens if it doesn't all melt in the first but just goes soft? - can you then push it through the other two? What happens when the filament flow rate changes? - if it slows down there will be too much latent heat in the system and it will drastically overheat the filament. How do you manage the potential heat creep causing blockages? What about pressure build up? What happens…........Oh never mind............

I never said it would work. Just giving him the option to power it up and see the results. -

The area of two 2.85mm diameter filament is 4mm, that's why i'm using cyclops and two extruders. I'll be using a couple of filastruder kits but I prefer to produce the filament first, because the filastruder extrusion speed is too low and so it would be the printer if I use it directly.

I've been thinking and I decided to make two custom heater blocks and I'll be using 4 or 3 heater cartridges in each. In this way I'll be capable of control the 8 or 6 heater cartridges with the duet wifi and duex5 (the heated bed will have a SSR). And I will contact E3D to know their opinion.

Some problems with this approach:
Cyclops only comes in 1.75mm, you can't use 2.85mm filament with it
Cyclops has a very high flow resistance, owing to the two 90 degree turns in each filament path
Having a melt zone 3-4 inches long will result in an incredible amount of back pressure. Hobbed gears will slip or the filament will buckle.
You do not need 240 watts of heat for this. In even a Volcano hotend, only about 15 watts goes towards actually melting the polymer. The rest is lost to conduction to environment.
If you're trying to use a 4mm nozzle size, you need 5mm or larger filament. Otherwise you won't get good melt uniformity.What is the end goal here? There has to be a better way to manufacture whatever it is you're looking to print aside from 4mm nozzle diameters.
