What do you do with the "coiled" wire when using a drag chain?

Hey guys I’m adding a drag chain to my setup but am not too sure what to do with the coiled wire connected to the Spindle mount.

Thanks!

This is important for anyone who is doing modifications (not supported by Onefinity and done improperly can permanently damage your controller, voiding the warranty) to their wiring like drag chains. There is a cable cross in all motor wires. On the X and Y wiring sequences, the center curly cable shown here is instead a straight cable contained inside the x and y metal inner tubes. Operation must include the inner wire. Direct connection to the stepper motor (without the inside wire) will d…

Do you sell an alternative wiring connection to the curly cable?

Hey Auntjemimma,

@Auntjemimma

I’m adding a drag chain to my setup but am not too sure what to do with the coiled wire connected to the Spindle mount.

this cable that Onefinity calls “curly” cable is NOT a cable made for permanent motion and can therefore make problems with internal cable breaks after one or more years of use. In an application where cables are being bent constantly because they supply moving components, I would strongly recommend to exclusively use cables that are made for permanent motion, like g. LAPP ÖLFLEX® or IGUS chainflex®.

If you retrofit a serious cable management to the Onefinity CNC machine, i.e. drag chains, it would not be logical to leave one stepper motor cable out.

Yes, there have been many times in which I was nervous that the Z curly cable was going to catch onto something as it was dragging on top of my work piece. This in turn has made me want to switch to a drag chain for safety concerns.
