brock x-axis cable chain for JGAurora A3S (and A5 I think)
Description
Revised 20191129: Link tolerances refined slightly. Reduces play between the links. Only revised the link files. Original Post: I designed this from the ground up as a learning exercise as much as anything else. And, honestly just cause it seemed like a fun project. I had no cable chain experience before making this so I am not sure exactly how the chain is supposed to behave but I think this one works pretty well. This assembly is really not needed but I didn't like the way the x-axis motor wires rubbed up against the hotbed and sometimes the hotbed connector. The assembly positions the cable away from the hotbed and controls its position at all times to avoid any conflict with the bed, bed connector or printed parts. The assembly uses existing screws on the printer to hold everything in place. So no new hardware is needed. I was having a lot of difficulty printing the very small overhangs used on the rounded edges of the parts. So I added a small wedge to serve as support which worked well but has to be clipped off with side cutters after printing. So I am including two sets of everything. One set has the support wedges and one set does not (for those who can print overhangs well). The cable retaining clip that snaps into place after the wire is laid into the chain is designed to be snapped in and out relatively easily but they are small so hopefully you never need to take them out. If you do need to take them out pry under them with a small screw driver or similar and it will pop out. The JGAurora A3S uses 13 links plus the upper and lower attachments. I am pretty sure this will work on the A5 as well but will require more links (17 or 18 links). It would be good if someone can confirm that.
