Duet 3 Expansion looses Connection

vali3d

I am running the version: RepRapFirmware for Duet 3 MB6HC v0.6 or 1.0 version 3.0beta12 running on Duet 3 MB6HC
Yes, it is allways the same board and the fault moves with the board.

@vali3d I would suggest you look at moving to 3.1.1 for the main board and 3.1.0 for the expansion boards first.

Ok, I have updated it now. This was quite some troubble, I had to completly redo the sd card. I will see if that helped in the next few days/weeks.
Thanks

Thanks. If that doesn't fix it, I will provide beta firmware for you to try. It turned out that the released firmware runs one of the PLLs in the chip out-of-specification, which could explain a difference between two boards even if neither is faulty.

Slightly off topic, but I really like the electronics cabinet you have (and that power supply looks nice too). Do you recall where/what model you purchased for the cabinet?

Hi,
the expansion lost connection multiple times over the past weeks. According to my obsevations, this happens only under a load on the extruder motors (which are connected to the expansion).

Can you send M122 Bx where X is the board number?

@Phaedrux When the connection was lost or in normal operation?

Hi,

I have checked the M122 B1/2 comand. The firmeware update I installed in September, didn´t install the firmeware to the expansions, only to the mainboard. Now I manualy installed the 3.2beta to expansions (with the M997 B1/2) an the mainboard. I keep you updated.
