Dear,

I want to ask for help with solving a problem with the device Duet 3 Mainboard 6HC v1.02.

After uploading the firmware via the web interface 3.5.4, the device stopped communicating. My colleague tried to upload via Bossa which worked until the Verify dropped this error:
Verify failed
Page errors: 1555
Byte errors: 788187

We tried multiple cables and firmware versions. Power supply was done via USB.

We have no idea what could be wrong.
Could we send the product to Duet3D in case you will not be able to help us online?

Best regards,
Matěj Konvalinka
