I have made some progress.
I inserted an SD card from a printer that doesn't work into one that does, and the same symptoms appeared. It appears that the printers are not working because of errors on the SD card. The only question that remains is what is causing them, because I find it hard to believe that so many SD cards broke at the same time.

@jdandcoke P defines the tool number in M563 eg:

M563 P0 S"hemera" D0 H1 F0

T[number} selects the tool eg:

T0

Yes it sounds like a problem with the SD card that would be covered by a warranty replacement.

Please send an email to warranty@duet3d.com and CC your reseller. Include a link to this forum thread and the details of your original purchase. You'll receive a reply with a form to fill out.

As for a work around, you could use DuetPi with the raspberry pi and connect it to the duet.

I ordered it from Filastruder to a US address on April 7th 2021.

Not a problem I will send them email.

Thank you again. This is all Greek to me so I rely heavily to you and the community for help.

i am greek and most of these looks greek to me to ....

the M665 is what defines a printer as a delta to my understanding.

M665 Rxxx( is the radious of ur builded printer the internal one), Lxxx( the length of the rods that hold ur effectors) Bxxx( is the radious of ur bed) abd Hxxx( is the height of ur nozzle to the bed when the limit switces are enabled) .
