These two footers were generated by the same factory file - one in V4.1.2, the other in V5
Not sure what's up with the build time estimate.
What prompted me to look at the footer was a file I'm running on a Duet2Wifi-based machine is not displaying a filament usage estimate.
DWC is looking for the "Filament length:" string - and I also discovered that on this one it is case sensitive. Length does not work. length does.
