CNC machines and 3D printers tend to have plenty of cabling which must be neatly managed while the machine moves. If not properly taken care of, wires can easily end up tangled in the moving bits leading to a dead machine at best, and some kind of raucous fire at worst. [Nikodem Bartnik] decided to create his own cable chains for his CNC build to keep everything in check.
The benefit of cable chains is that they stop cables splaying everywhere while still allowing them to move as needed with the axes of the machine. [Nikodem] created 20mm and 40mm chains for his build, affixed into the aluminium extrusion with bolts and T-nuts for easy assembly. The chains are assembled by hand, with 3D printed clips that hammer in place to hold the cables inside once inserted.
Of course, there’s nothing stopping you from buying cable chains off the shelf. But if you don’t want to wait for shipping in this era of cursed supply chains, or you want a cable chain you can customize to perfectly suit your machine, making your own could be the way to go.
