I’m installing my new laser system and I moved my control boxes so they are more accessible for service. It turns out my laser control XLR is just a tad short to get to the top box which is roughly at eye level. Would there be a problem extending it 5’ or so with a 20 or 22 gauge shielded mic cable? If not I can swap my VFD (bottom box) with the new Aux Box (top box). All my other cable are plenty long enough. ![0](https://canada1.discourse-cdn.com/flex027/uploads/avidcnc/original/2X/3/3eb042e6cc2f70e99aa459e4ee5a4e2577650ac6.jpeg) ![image](https://canada1.discourse-cdn.com/flex027/uploads/avidcnc/original/2X/9/961365b6570db4e23ffd4a55221a9d2d58553789.jpeg) ---

It should be fine to extend it. That cable you show is wrong however, it’s supposed to be a 4 pin cable. Contact support and they can get you setup with a longer cable (we stock those as they are the motor cables for our stepper systems) ---

I misunderstood what was getting plugged in and where. The XLR from the laser head goes to the remote arming box and the remote arming box goes to the aux box. I have more then enough cable and flexibility.
