My Cr10S is my oldest working FDM printer. It is still very relevant as it as a 0.8 mm nozzle permanently installed and is used for large, fast and dirty prototyping.
With a lot of spare 24 volt parts left over from other upgrade projects I decided to convert the CR10S to a 24 volt system & add Klipper and a Klicky Probe.
I repurposed a redundant Ender 5 Electronics Enclosure, removing the separate control box altogether.
Various junction boxes and cable chains improved the CR10S`s awful wire management.
