Hey Tyler,
probably everyone who decided to retrofit drag chains to the machine.
But it is also a question of design. The Onefinity CNC is absolutely unique in its design. It rather looks like a piece of art than a hobbyist CNC machine. Or can you say this was no point in deciding to buy it? Unlike other CNC machines, the linear rails are the axes. It’s these chrome-plated, hardened steel hollow shafts that make the difference to the competitors which produce CNCs that are without exception ugly. So hiding the cables is part of the concept.
Drag chains will be on the outside of the rails, but they usually are on the back of the X rails and drag chains can at least look better than raw cables attached all over the machine.
As cables and connectors rather fail where they are moved and less inside a tube, I think disassembling everything would not have been necessary. If you had found the help documents and also e.g. the postings Retrofit strain relief to your machine, which the machine unfortunately lacks (and maybe also in this case you may want to procure what is needed to make new cables) before beginning to disassemble something, your problem would probably have been solved by servicing, repairing or exchanging one of the connectors or cables that are subject to permanent motion (what these connectors are not made for, since they are made for internal electronics), but are easily accessible and visible. So I would have a look at the cable that goes from the the beginning of the X axis on the left to the controller, and also have a look at the socket in the left X axis foot, which is where the people linked above retrofit strain relief – exactly for the reason that failures appeared.
A bipolar stepper turns when four signals on four wires appear in a specific order. In case one of them fails and one of these signals is missing, the stepper does what you have shown in the video.
that is perfectly possible. These connectors are only tin-plated, which either leads to corrosion, but they are also made to be put together exactly once (and not disassembled multiple times) which can lead to the extremely thin tin layer to be scraped away and the bare copper to be exposed to air humidity which can make him corrode rather quickly. Also if you use the wrong crimping insert or the wrong cable gauge or your employee that makes the cables is not fit, you get pins with wires that come out on motion (remember, motion is not what these connectors are made for). And what do you think why they are so prominently appearing in the help document above.
