@t3p3tony Just updated the firmware and I can confirm that the MAC is correct. Thanks

@dc42
If you are looking into that code. The hex format also doesn't seem to work anymore, not sure if you are removing backwards compatibility, but if that is the case a note would be good on the M540 description.

M540 P0xB1:0xEF:0xD0:0xAD:0xDD:0xFD ; This format doesn't work anymore
M540 PB1:EF:D0:AD:DD:FD

Thanks a lot for the fast response.
Sergio

@dc42 Thanks a lot.

@t3p3tony
3.2 doesn't resolve the issue.

@dc42

None of my Duet3 change MAC address.
Here is another example:

Sorry, I was asking someone to turn off that machine in that factory. I cannot access both remotely through the VPN so I needed remote hands to help me.

@dc42

@t3p3tony can confirm on his test base, I guess it could be a firmware issue?
I will try to go down to 3.2 for the machine that is in conflict, since it is not very happy in the network.

@t3p3tony

Will try 3.3 stable, and it is stand alone.
We use it pretty much as a duet 2.

More tests, updated firmware to 3.4 Beta 4

Board: Duet 3 MB6HC (MB6HC)
Firmware: RepRapFirmware for Duet 3 MB6HC 3.4.0beta4 (2021-09-27)

Turned off network before changing MAC
M552 S0
M540 P00:AD:BE:EF:CA:00
M552 P192.168.102.101
M554 P192.168.0.1
M553 P255.255.0.0
M552 S1

Stills gives:
Unicast reply from 192.168.101.121 [BE:62:38:3A:53:37] 0.994ms

Second duet in conflict:
Unicast reply from 192.168.102.105 [BE:62:38:3A:53:37] 1.384ms

M540 gcode returns the right MAC, but it doesn't seem to be propagated to layer 2.

Hi,

I have an issue with Duet 3 Ethernet. I have two machines that report the same address BE:62:38:3A:53:37 and i get a conflict on my network.

I tried different formats:

M540 PDE:AD:BE:EF:CA:FE
M540 P0xDE:0xAD:0xBE:0xEF:0xCA:0xFE

I test using arping and I can see the MAC addresses changing on the Duet 2 - Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.2 (2021-01-05)

But Board: Duet 3 MB6HC (MB6HC)
Firmware: RepRapFirmware for Duet 3 MB6HC 3.3RC1 (2021-05-01)
doesn't seem to be changing with the same config/code.

M540 reports correctly the new MAC address specified on the M540, but arping reports the original interface.
It doesn’t seem to change. I have around 20 Duet 2 printers that can change the MAC correctly in but firmware 3.3 doesn't seem to work.

G90
M83
M550 P"AM_NAME"
M540 PDE:AD:BE:EF:CA:FE
M552 P192.168.102.101
M554 P192.168.0.1
M553 P255.255.0.0
M586 P0 S1
M586 P1 S1
M586 P2 S1
M552 S1

This is my config start setup, any recommendation?
Best
