Error: M550: Machine name must consist of the same letters..

For the Duet 3/RPi, is it possible for the machine name defined in M550 to not match the hostname on the RPi? Or could the name displayed in DWC and the PanelDue be defined another way? The character set is quite limiting being forced to match the hostname on the RPi..

FYI, this has been tested on a Duet 2 without the limitation and everything appears to work fine with various other characters.

Thanks

Possible, anything is possible; the question becomes is it worth the effort?

For the Duet 2 M550 is still tied into the network hostname, mDNS and all that jazz - so you really ought use a valid hostname for any M550 command.

If you highlight what you perceive as the shortcoming maybe the devs will have an alternative approach to suggest, as the hostname needs to be set with the limtiations of the dns system in mind.

@bearer Fair point.. and I didn't understand that about the Duet 2 as I only see it registering on our wifi as the MAC address. So I guess what I'm really asking is if M550 could set machine name as well as a display name..

From raspi-config: RFCs mandate that a hostname's labels may contain only the ASCII letters 'a' through 'z' (case-insensitive), the digits '0' through '9', and the hyphen.

A space character is the simplest example.. but a better example is that we'd like to display the full name of our machine in DWC and on the PanelDue, which is "oozeBot ele^gant" - both the space and caret are not allowed.

So you basically want a vanity plate for the DWC label?

Sure! This is the wishlist category.. If DWC and PanelDue has to be tied to hostname, so be it. However, we can't be the only one who'd like to be able to personalize this a touch more..

@oozeBot what you want is a tweak on DWC to display your logo!
