SD card problems

Dmitry Black

Hello!I updated my printer with a new board (Duet 3 mini 5+) and ran into a problem. When I try to upload a file, the process is interrupted, and starts again once. Then I get a few errors and lose connection with the DWC until I restart my Duet.
The 12864 screen also loses files and stops displaying the menu.
But sometimes it is possible to upload small files right after the board is turned on.
I've tried different firmwares including Release 3.2.2, 3.3beta2
Also i tried different memory cards, including the high-speed sandisk ultra 32gb from gopro.
My board Duet 3 mini 5+, rev.0.5, purchased from filafarm.de

Hi @dmitry-black, I'm sorry that your Duet appears to be have an intermittent fault on the SD card interface. Please ask Filafarm to replace to under warranty. You may refer them to this post as authorization.
