Robo3D Cable Chain Quick Install No Rewire or Carriage Replacement

thingiverse

I liked the design from InAppDesigns, but it looked like a lot of work to install so I remixed his stepper cover and built a new open chain design. This is my solution for adding a cable chain, which incorporates several key goals. These goals include installing without major tear-down or reassembly of the printer, not requiring a re-run of all wires, maintaining full X and Z-Travel at Z=200mm, quick installation, links that don't come apart or break easily, and no binding of any kind. Here's how to print my solution: Print 18 top links, 17 bottom links, 1 attachment link, 1 stepper motor mount, 1 wire cover. First, install the cover over the stepper secure with one M3X8mm screw as seen in the picture. Next, route the wires and install the wire cover with two M3x5mm screws. Remove all but 12" of the original split loom. Then, install links alternating between top and bottom links around the wires. Mount the last attachment link with some 3M tape or a Command strip using the picture as a reference. That's it! If you need to remove the cover, simply unlink the chain at the attachment link and pull the chain away - no need to remove the attachment link. If you're having trouble with links breaking, make sure to use high enough temperature for good layer bonding. I've been using 210C for Hatchbox and the links are very tough to break. The top links are arched so you shouldn't need supports. If you do, your print cooling may be inadequate. For fans, consider using 40x40x15mm or 40x40x10mm since the 20mm deep fans don't clear the Robo 3D cover at high Z travel. Update: I've figured out how to change my STL files so all of them are oriented correctly for printing. No supports needed! Here's how I print with this design: Printer Brand: Robo 3D Printer: R1 ABS + PLA Model Rafts: None Supports: None Resolution: 0.2mm Infill: 25%
