@dc42 Thank you

I just did it and everything looks to work , even the modem connecting again.
I still don't understand what kind of mistake and how many I did, I'm new in this field and I must admit that for me is much more complicated than I thought.
Thankyou !

I understand, but i found config (1), config (2) etc files..
I think that at this point I will look for a procedure to clean and reload firmware .
Hope it will not be so difficult..
Thankyou

I checked the SD card and I found several config .g files , I think that trying to update the software i did a mess !
However the M552 S1 command was present in all of them . I deleted the other config files thinking that they could conflict leaving only one of them, but the problem is still there. At this point I ask you if I can clean the SD card, reset everything and reload drives and updates from the beginning...

Hello everyone,

After some attempts to update the firmware of my Duet WIFI I managed to install version 3.0 (it was 2.02).
The card connects to WIFI only through the USB connection with the M552 S1 command on YAT. From here I can launch DWC and everything seems to be working. The problem arises when I close YAT disconnecting the USB cable to connect via Browser.
When the board is turned on, the Blue LED does not flash and always remains off, consequently DWC cannot connect.
I attach some photos hoping they will be useful to understand the problem
Thanks in advance for any help.
This is the screenshot of DWC connected with USB Cable and YAT with WIFI activated via M552 S1

This is the card connected with USB and YAT

Thankyou

Yes I have two Z motors running in parallel connected to ZA and ZB slots on the DuetWIFI.
I'll change settings as you suggest, changing the Z4000 to Z 400.
Thankyou!

@Phaedrux
Thanks for the formula, I had been looking for it for a long time ...

@PuterPro

thank you
in fact I had many doubts about how to insert the Cofig file on the forum, now I know.
in a week I will finally be home and I will put all your suggestions into practice hoping to be successful.

Goodmorning everyone

I'm still far away from the printer for work reason, but I have my laptop and I elaborated the configuration file, same as I did at home and loaded on the DWC , processed by the RepRap cartesian configuration tool. Compared to the default data available on configurator I have entered only the essential data omitting changes about the dynamics of the axes (also because I don't know exactly which data to put for lead screw axes ) to have a file that for the moment allows me to homing and make the machine move correctly.
Instead of the Zprobe, I temporarily installed an NC limit switch which trigger at about 2 mm from the heated plate.
I have available and connected to the Duet two limit switches for every axe ( I think i have to choose one as the option on configurator is"low or high end"..) and they are NC .
Heated Bed is 310 x 310 , but the axes have a stroke of about : X 410, Y 410 and Z 290.
Attached all the config files,
Thank You.

@Phaedrux
Thank you so much for your kind help. I touched the motors after a second attempt to run a Home all axes and they were quite hot. But maybe was only impression I don't know.
I'm living for work tomorrow morning, far from home (and my printer ) for about a week. As soon I'll be back home I'll send you my Config file as come out from rep rap configurato for custom cartesian. In the meantime I'll study about your advices.
I'm so happy to know that somebody helping me.

Good morning everyone.
I have just finished my creature, a Cartesian with three 8 mm / 2 screws on X,Y,Z ( double Motor on Z), Nema 17, NC limit switches on both sides of each axis (later the lo one will be replaced by the BL touch probe).
The extruder is a Flexion HT.
The heated print bed is 310 x 310 mm and the stroke of the axes is much longer.
So far, a lot of work but very pleasant for me, now a big wall in front of me: programming the Duet WIFI card.

I have already tried with the RepRap configurator but with no success, problems for homing, too slow speed in movement, overheating of motors and overrunning of endstops. It is a new world for me and I have to study.
I wonder if anyone can help me with a Config file suitable for this type of machine ( three lead screw axes).
It would be of great help as a basis to begin to understand and tidy up in the great confusion I have in my head
Thanks to anyone who can help me.
