CTC/Replicator/Flashforge X-Axis Cable Chain

thingiverse

I love GeraldO's design, but wanted my cable chain up as high as possible and out of the way. With just chain links, it hung down quite a bit, and looked a little weird. (See the last picture.) As GeraldO says - The strain on the X-axis cables of the CTC/Flashforge/Replicator printers has been documented to cause the endstop cable and/or the X Stepper motor cable to break and potentially cause a fatal short, often destroying the mightyboard controller. I have not experienced this, as I became aware of this design flaw soon after buying my printer, and took precautions to prevent this failure. His design works great, but I wanted to re-mix it a bit to suit my taste and put the cable chain as high as possible in the printer. I re-mixed the bracket to span a little more than 1/2 the distance of the chain, that way it can be mounted up high and out of the way to still allow for good access to the print bed from the right side opening. I also designed it with openings to capture two standard M3 Nylock nuts. The other parts are exactly the same parts that GeraldO designed. In my re-mix, I only needed 12 links, so you may want to just print a dozen (or perhaps 2 or 3 more if you mounted the arm lower than I did) on your CTC to be perfect! But if the cable gets too tight, you'll need to add a link or two. Pull your Y-axis all of the way to the front of the bot and continue to assemble the chain until the end comes up to the bottom of the stepper motor. There should be enough slack such that when the carriage moves to the extremes, the cable chain should never be pulled tight.
