Finding the MAC address

[heoconnor]

Looking for the MAC address to register my duet with IT services where I work (to connect it to the ethernet). Is there a command I can use in YAT to find this?

Should be part of the output of M122but do take care to set the line ending to LF if on windows.

M122 just comes back with: Emergency stop! Reset the controller to continue.ok

Your IT dept could tell you the MAC address if they wanted.
You could plug it into the network tell them the IP address and they can find the MAC that way.
Or ask them for an IP address, set it, they can scan and cross reference the IP to the MAC.

MAC address is usually set in config.g.

[DocTrucker]

Run M540

Edit: M540 on its own should return MAC address. Read the link to see how to set MAC address.

Run M540

aye, that works! didn't see it was specified ethernet, and not sure if it works for the wifi?

[DocTrucker]

@bearer Oh yeah, didn't think about the wifi half of the equation!

[DocTrucker]

"Note on the Duet 2 Wifi the MAC address is unique and set on the Wifi Module so this command has no effect. The default MAC address on a Duet 2 Ethernet is generated from the unique processor ID so there is normally no need to change it."

So trying to set it with M540 won't work. Whether or not it reports the correct address would have to be checked. Can you access your router and confirm from there?

OP seems to be on Ethernet so thats okay, I was just curious about the wifi for future reference; ultimately a moot point as M122 doesn't seem include mac address for Ethernet (on the Maestro at least)

I think you might have sent M112

@Danal neat, copies directly to linux to:
