Duet3 SBC not connecting "DCS is not available"

toddel

Hello...

i have the same problem as mentioned here:

https://forum.duet3d.com/topic/15551/duet3-pi-flashing-diag-led-after-wiring-24v-dcs-is-unavailable/148

I tested a pi3 and a pi4. Both say DCS is unavailable...

It's very technical and i don't know, what to do now...

Standalone Mode is working.

Danal

please run M115 from the "console" tab on the web interface, and post results here.

On the Raspberry Pi, please run

apt list duet\*

and post the results here.

The Web Interface is not responding.

You tried to upgrade to RRF 3.01-RCx but that version isn't supported with the latest stable DSF version 1.xx. Either upgrade to the latest unstable version (see https://duet3d.dozuki.com/Wiki/Getting_Started_With_Duet_3#Section_Software_Installation) or run M999 P"ERASE" from a microUSB connection to the Duet 3 and reflash RepRapFirmware 3.0 via bossa.

Thanks for that input....

Which Firmware should i flash? All are RCx....

@toddel said in Duet3 SBC not connecting "DCS is not available":

the easiest is probably to the file in /opt/dsf/sd/sys/Duet3Firmware_MB6HC.bin (when the apt package for repraprfirmware is up to date it should be the correct file).

but the latest stable release to go with the latest stable dsf is RRF 3.0.
