Help Cable Management

[bmacoubrie (Brad)]

Would some of you who have good cable management care to show pics or advise. I am ready to be serious about my cables.

Thanks

You can see my cable management here:

MPCNC Primo Schneewittchen Reanimated - Oldenburg, Germany

Today’s bad idea: planing the spoilboard in your office because you don’t want to carry the CNC to the shop… [IMG_20240328_144342] [IMG_20240328_144348] It looks great though. Now with acrylic for that extra little bit of flatness: [IMG_20240328_162718]

X/Y got the tape measure trick, the gantry got a drag chain with a L-profile. Works well.

+1 on the tape measure trick.

I used a combination of heat shrink, mesh loom and corrugated split loom for cable management.

The pictures are for an LR3, but are pretty much applicable for an LR4.

Big Red Lowrider 3 Cable Management

Build thread is here…

Introducing - Big Red Lowrider 3

[Big Red Lowrider 3 - Overview] Big Red Lowrider 3 has arrived! While all the cool kids were playing with their Kobalt Routers, Jackpot Boards and LR4 Beta builds, I’ve been slowly (very slowly) upgrading and expanding my earlier “Little Red” build into its much larger (and much redder) replacement. @vicious1 has claimed the title for “World’s Sexiest Lowrider 3” (although the post seems to have disappeared), but I think that this one may be in the running for honorable mention… …

after looking at the big red lowrider, I have changed my mind and instead of offering wiring advice, I’m taking notes. Very nice! Built to last.

For those of us with less confidence in our wiring skills to not bolt it all down and heatshrink it together all permanent just yet, I might suggest some wire trays or cable chains. I’ve seen some helicopters use string for their wiring so it can be easily redone, so that might be an option.

@bmacoubrie Noticing that you asked specifically about the mpcnc, when I had mine, I ran the wires from the controller under the table or through the stationary tube to the far side of the table so loading and unloading didn’t involve wire gymnastics. The far side of the table had cable chains for the x and the y and then the x tube had an extra cable on it for the gantry z motor and touch pad and can be seen in the photo below. While this certainly isn’t the ideal for wiring, it is an example of where you might consider placing your cable chains should you choose to go that route.

• controller is far right in this photo (not pretty)
• y cable chain is in the rear with cables entering from the right from the controller.
• X and Z cables go through the back x tube to the far left corner and then enter the cable chain to the moving x tube and all but the far motor cables go through it to the front x motor and then to the z motor cable chain mounted on a thin board that is connected to printed tube mounts.
• The z and the touch plate wires go through that chain which terminates on a printed extension from one of the core bearing supports (has a couple extra holes in it. No pressure is put on the z axis, just the wires go to the motor.

Forgive the rough wiring, the intent is to give an idea of placement to get wires to everything. I’m taking notes on the big red build for how to get the wires in a more permanent state and looking and functioning correctly. I soldered and crimped connections to each motor at the motor after I had problems with one of the motors (this was unnecessary).
