fail to establish connection between 6HC and multiple 1XD boards
-
@gloomyandy the single board did syncing when connecting at first, but suddenly it lost the connection, it is not stable. Thanks for your suggestions
-
@Joseph Hmm that's unusual. I'd be looking very closely at the cables and the plugs/sockets (and possibly the soldering around them), if all of your 1XD boards when tested alone (and with different cables) do the same thing I'd be looking very carefully the the socket on the mainboard. But maybe the Duet folks have some other suggestions?
-
@Joseph please provide a photo showing the single board setup wiring as well as the basic config you are using to test the connection.
Also provide the output of M122 and M122 BX, where X is the CAN address of the board you are trying -

Hi here are the photos. It is very wired, sometimes the board can flash synchronously, but when I send M115 code, it seems that the mainboard can't read it.
I guess maybe the mainboard failed?
BTW I posted all my confiig.g code above, which has a black background . -
@Joseph you might want to unplug everything and start again. but i don't know how much further traction you'll get with support knowing they are cloned boards.
-
@Joseph Is your 6HC a clone board as well?

@droftarts yes

@jay_s_uk ok, thanks for your helping!

@Joseph If you can't connect to DWC over the network, that would seem to be more related to the Raspberry Pi (or whatever SBC you are using). For the board, it's hard to say what has changed that has caused this failure. It's possible something has failed on the 6HC, but given that it has come at the same time as the SBC losing network connection, perhaps that's the place to start looking.
As all your boards are clones, there's not much more I can do to help.
