SPI connection lost - broken DUET3 6hc ?

IndeX4D

@chrishamm
I used a different (and working on other printer) Raspberry, cable for power the pi, Ribbon Cable, 3 different sd cards.
No change.... I also used the updatet version of duetPi and the older ones which came out in january ( the experimental boomwork). Can you please tell me which I should use? Raspberry pi 5....

ESD? The backside of the duet 6HC looks fine. Or where should i look. I also recognized, that after long power OFF, the printer is resetting in a slower way and one time I could home.
But when I want to make a prompt, it gets worst.

I´m going to print in standalone mode, now. I´ll report.

I got my board a few weeks ago from Dold-Mechatronik.com

@Phaedrux When I try to connect with YAT .,.... not possible.

Edit: sorry, I haven´t seen your post. Still a case of warranty?
thanks

While DWC is ´´disconnectedt´´ , I could make a M122.
Strangely, after reflashing the image, the printer is starting quiet normal till the first prompts```

hey,
sadly I have the same Problem with the new board.
I tried different raspberrys.
It´s quiet strange that I could print 2 or 3 times. When I wanted to print next day after switch off, the printer is stuck in the error loop.
How can It change so crazy. Working one day, next day broke till maybe 2 hours later it´s suddenly working..?!
I need some help.
All other printers are running completely fine.

@IndeX4D that error is nothing to do with SPI. It tells you theres an issue with the CAN connection to your other boards

IndeX4D

@jay_s_uk
ok thank you.
the topic is almost 0ne year old, sorry

Funny fact. I had to return the last board because of that problem.
Thanks a lot
Is there a way to finf out more about the problems?

jay_s_uk

@IndeX4D i guess its a wiring issue

IndeX4D

@jay_s_uk
Probably... but between the can connections?
I have this expensive shielded cables...
let me check!

IndeX4D

@jay_s_uk
I disconnected the can cable from the mainboard and I have still the same problem.
Can it still be a wiring problem. I think it can´t be?

jay_s_uk

@IndeX4D post a photo of the connection between the mainboard and the pi

@IndeX4D For "Timeout while waiting for transfer ready pin" errors, see https://docs.duet3d.com/en/User_manual/Machine_configuration/SBC_setup#troubleshooting

This error, reported in the DWC console, is usually caused by:

Other wires running too close to the ribbon cable, creating interference. Heater and motor wires can be particularly noisy, route them as far away as possible.

Ribbon cable too long, damaged or poorly connected. Check installation of ribbon cable. Ribbon cable should ideally be not longer than 150mm.

Signal reflections have been reported by one user. This may have been caused by a ribbon cable that was too long, or damaged.
