My current set up has the AC power running for the router and the 24Vdc power brick into the gantry and then to a retractable extension cord on the garage ceiling.
Depending on where the CNC is, the cables have a tendency to snag on a hose hook. Which messes up my X position mostly but is kind of annoying.
I am wondering if I can keep the brick outside the gantry and feed DC wires up to the jackpot using dragchain, as well as run extension cord for the router through the same drag chain. I do not have experience with this type of thing so I am at a bit of a loss on where to start thinking through the process.
Also, the E-Stop locationā¦where would you guys put it. Currently I am using the reset on the ESP3D webUI for the āE-Stopā but it isnt really what I want. I would like to cut router and cnc power simultaneously. How would I go about doing that? Thank you!

There are two general approaches to the E-stop. First, you can use a switch on the AC power that controls both the router and the power adapter for the CNC electronics. The simplest version is just a power strip with the switch well placed. On my old machine (Burly), I wired an E-Stop switch into the corde of a power strip.
The second method is to control the router using a mechanical relay, or an SSR, or an IOT relay. All have successfully been used. When power is cut to the control board, the relay is deenergized turning the router off. On my current (Primo) machine I use an IOT relay. A bit of g-code is automatically inserted into my g-code scripts to turn the router on and off. If you go with an SSR, you want to oversize it somewhat for the routerās inductive load. A 40A one has been suggested.
Iām sure you will soon get experienced feedback about running AC power through the drag chains. I donāt have a LR, but my one concern would be electronic noise. This was a problem with the LR3 builds using long wires for the display and SD card reader, but may not be an issue for your electronics.
thank you for the suggestions!! I do have other extension cords that are not mounted to the ceiling so I can easily attach a power strip to the side of my table for this!
I have my power brick mounted under the table and the cable running with a USB cable and the routerās power through a drag chain (I use another board though). Works completely fine.
I do this as well. I run a larger power supply and take 24V up through a drag chain. I take mains up for the router and a USB for Lightburn. My drag chain is big enough for a small silicone tube supplying air for my air assist also. Works really well.
