@droftarts Hi Ian I continued to work on finding the right configuration. I used the information you sent me while remaining in RRF2 but the results were not good. I then decided to saturate all the Hw connections of the DUET2 board before engaging those of the DUEX5 and I subsequently set the indices of the heaters, motors and tools accordingly.
I connected the 5 motors for the axis movements to the 5 Duet Driver Chips and I inserted the BLTouch at the end of the PWM chain of heaters on the DUEX5, and the result was excellent.
I send a pdf that shows how the boards have been connected to sensors and actuators and the config.g file generated manually with the correct indexes plus M584 X0 Y1:3 Z2:4 E5:6:7:8 P:3 instruction to Map motors on axis(/assets/uploads/files/1583499901268-final-connection-schematics.pdf) .
I didn't switch to RRF3 because I achieved the goal with the 2.5 release of the FW and because I saw that the command syntax in RRF3 is much more complex and needs further study on my part.
Thanks for the great support you have given me.

@droftarts Hi Ian, thanks for your help in solving all these problems. I am sorry that discussions may arise that do not help to reach the goal and are only a cause of waste of time.
I confirm that the Json config I sent was created with the configurator and that the sent config.g corresponds to that generated at the same time by the configurator.
I will follow your advice and install RRF3 so everyone will benefit from it.
I will test with the version of config.g you sent me.
Thanks again for your valuable support

@infiniteloop Thanks I'll keep your suggestion in mind. Having already the pump and the water-air heat exchanger is a good idea to consider the circulation of water for the benefit of the motors.

Hi Ian I am very sorry that there are all the constraints you have indicated to me. The obligatory way seems to me the one you advise me: "So I think a better solution is to move the heated bed SSR control back to E1 (H2) on the Duet. Then have your four hot ends on E2 (H3), E3 ( H4), E4 (H5) and E5 (H6). This leaves E6 (H7) available for the BLTouch "
I would like to receive coherent .g and .json files for this solution. I'll let you know if this configuration also solves the display problems.
Thank you very much for this special support.

@infiniteloop Hi, the printer we are making has a print volume of 500mmx500mmx500mm but the external size as you can imagine is much larger (about 0.35 cubic meters). Our target is to print Peek and Carbon Fiber charged polymers for professional application. This is the reason for thermocouples on nozzles , a powerfull Bed heater driven by SSR device, and also water cooling of the extruders. The heating of the printing chamber and its control will be another problem to be solved.
As we say here: we cross our fingers!

@droftarts Dear Ian thanks for the timely response, now I understand why I could not correctly configure the tools on the Display. As you suggest I will connect the bed heater to channel E2 so all the heaters will be in sequence on the DUEX5. For the BLTouch I have not found connection schemes recommended to the Probe In connector of the Duet Ethernet and I have read about some problems of compatibility of the timing of the control of this port with the BLTouch. Would it be possible to use the PWM signal of one of these heaters: H0, E0, E1? Where could I connect since there are no specific connectors on the Duet for these PWM channels?
Thanks for reminding me that I made a big mistake by increasing the driving current of the motors in series.

@droftarts Hi Ian here is a resuming of actions I have performed in accordance with your message:
I have updated Duet2 Ethernet FW following the Fallback procedure #1 ; after this action the Answer to M115 command is the following:
FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 2.05.1 ELECTRONICS: Duet Ethernet 1.02 or later + DueX5 FIRMWARE_DATE: 2020-02-09b1<LF>ok<LF>
I have also checked that the DWC version is 2.07
I Have added a straight ground cable connection between Duet2 and Duex5.
I send some picture of the printer, of the display apparence , some DWC screenshot and config.g + config.json file you mentioned.
I have updated the connection pdf doc. adding the evidence of the connectors used for the filament run out switch for each extruder motor.
At the moment the printer perform correctly Home X, Home Y and home Z , this last one with the use of the BLTouch device connected as per the connection .pdf document.
After this the printer perform correctly the levelling macro actioned by the display.
What is fully incorrect is the matching of : tools-heater-temperature readout on the display and on DWC interface.
I tried so many differnt configuration in RRF Configurator using the name of the extruder motor (E3,E4,E5 and so on ) instead of drive number (6,7,8,9) and PWM number ( 2,3,4,5) instead od heater label (E3,E4,E5 and so on) but I alwais had back wrong Display configuration and bad tool / heater assignement.
Can you explain me the rules to make the correct assignement inside the configurator.
So many thanks

First of all thank you for the detailed answer. I see I misled you because of an error in my pattern. The limit switch X is only one and the other aside is the limit switch Y.
Do not consider the final configuration and only consider the initial configuration with the motors connected in series.
The RRF configuration tool should be able to support this initial configuration, right?
I was unable to find the right labels to select in the configuration tool to assign the correct extruder motor to the tool, along with the correct heater label.
As a result, the display shows an incorrect temperature associated with an incorrect tool. Furthermore, the BLTouch works with the console controls, but it does not work when I use the Z axis.
I am studying the documents you have suggested to me but I find it very difficult to succeed in this first configuration.
Thank you if you can give me some further indications on how to proceed.

Hi Paul

This time I have used Duex5 to support a more complex hardware configuration for a big size 3D printer. I have several time tried to configure the Duet2 Etherneth and the Duex 5 expansion board unsuccesfully ( tools do not respond correctly from the display, BLTouch do not work properly and so on ). I annex the hardware schematic I realized with few comments added. Can someone help me to get the right configuration ?
Many thaks
Paolo
