I have a Journeyman, on a QCW, and my M2 wire is JUST about able to reach the controller.  
I also occasionally use the JTECH rotary, which requires me to plug and unplug this cable.

Is there any reason why I can’t run the 2’ extension cable ([this one)](https://www.onefinitycnc.com/product-page/2-pack-cable-extensions-2-foot-long) out of my M2 port, and swap my M2 plug and rotary back and forth? It’ll give me much less strain on the connection.

Any draw backs? I assume this cable is supported, but in this application?

Hey Paul,

I see no problem, except that these connectors are not made for frequent plugging and unplugging. Did [this solution](https://forum.onefinitycnc.com/t/custom-cable-for-rotary-addon/17663/4) not work?

Thanks

It did not. We chatted, but with the holidays, the chat died off. I haven’t come back to the rotary since then, so it wasn’t top of mind. I did buy the extension, and will use it - I don’t expect to be swapping the connection too frequently, but it’s considerably easier to do that than try and get the M2 plug from the back of the controller.
