FREQUENT DISCONNECTION

SANJR

Hi

I am using a Duet 3D mainboard 6HC and an expansion board 3HC. The 6HC mainboard was replaced with a newly purchased board, while the expansion board is retained the one that was purchased 2023. On powering both the boards i facing frequent disconnection.

Is this something related to the software version of the boards?

Any suggestions please

@SANJR what firmware version are you running & DWC version, how are you connecting to the board (ethernet or the wifi module? Do you have a PanelDue?

Hi Tony

I am connecting via ethernet

And the vesion of the boards are as follows
DWC : 3.4.5
Duet 3 MB6HC : 3.4.6

Previously i had multiple motion system. Since i was getting an error of M596 COMMAND ERROR.

I currenlty removed this configuration and trying to start with a basic setup.

I was testing the endstop status by sending M119 command. I was able to detect the Z axis, however i was not able to get the X and Y axis endstop.

For better understanding i am pasting my config.g files for reference```

@SANJR what is diconnecting? DWC or something else?

SANJR

@dc42

Yes its the DWC

Gettings alternate messages - Disconnected and Connection Established.

Now i have removed the multipled system.

The endstop is not able to communicate when a M119 command is sent from the DWC

@SANJR said in FREQUENT DISCONNECTION:

DWC : 3.4.5
Duet 3 MB6HC : 3.4.6

Please update the system to 3.6beta4
It looks like you have a 3HC in the system as well so be sure to update that as well. ideally in the following order:
Update 3HC
Update 6HC
Update DWC

Multiple motions systems is only supported from RRF 3.5 and later.
