How to visually (DWC) identify multiple Duet printers

jens55

I am thinking of converting my second printer to Duet but am concerned about having two identicat DWC instances open.
Is there a way to rapidly identify which printer goes with which DWC instance without looking at the IP number and doing mental gymnastics? As we get older, mental gymnastics gets to be somewhat error prone.
Currently, on the top left corner of the DWC screen is a big bold 'Duet'. Is there a method of changing this to read 'Printer 1' or 'printer 2' or something along that line ? It's on virtually all menus and provides a clear indication if you are about to reset the printer that has been running for 10 hours .....
How do print farms handle this sort of thing ?

@jens55 you’ll want to set the M550 command in your config.g : https://duet3d.com/wiki/G-code#M550:_Set_Name

Thanks, that is exactly what I need!
I stuck my M550 P"printer 1" in my config.g, saved it and reloaded but there is no change in the name. Do I need to something like resetting the computer that DWC runs on? Maybe a power reset of the printer instead of resetting config.g?

Glad it’s working for you!

Just adding that if using DSF (raspberry Pi) current versions will also require you to set the hostname in linux to match M550 P"myprinter" with sudo raspi-config nonint do_hostname myprinter

Don't get creative with spaces or special characters.

@bearer thanks! I’ll be setting up a Duet3 with RPi soon and didn’t know that!
