I am interested in using RJ45 connectors and cat5 cables on my MPCNC, as others have done. I have a crimper for putting the plugs on the cable, but I’ve never worked with the jack side. From what I’m seeing, it looks like the punchdown style would be easiest to work with, but I wanted to hear from folks with some experience using RJ45 jacks have to say.
If you use the punchdown type, does that require a special tool? Also, is it possible to use stranded wire in a punchdown? I’m using breadboard jumper cables cut in half for making the connections to the ramps board, so would like to connect those to the RJ45 jacks.
Any advice is appreciated!

The punchdown RJ45 modules that I used all came with a simple plastic tool. I think that most or all ethernet wire is stranded. All of mine is stranded and works great. You probably already saw my scheme http://www.thingiverse.com/thing:858155 and http://www.vicious1.com/forum/topic/placement-of-electronics/#post-4376.

Thanks, Steve. Glad to know I can use the punchdown ones. I did see your forum post and design on thingiverse. I’m really looking forward to having the quick connect/disconnect capability!February 19, 2016 at 1:39 am #7857
I think this is a great idea first off. My only concern is is can cat 5 handle the amp draw?February 19, 2016 at 4:37 am #7862
i have yet to find “ethernet” wire that comes stranded. it comes in twisted and flat but not stranded, unless youre talking cheap cat3 or walmart premade ethernet hookup wire.February 19, 2016 at 4:38 am #7863
this was my concern at first until i remebered that i ran all my speaker wires in cat6. ive been using cat6 to run my mpcnc just fine.February 21, 2016 at 9:12 am #8031
If you’re going to use ethernet cable, use cat6 patch cables. Cat6 wire is larger gauge than cat5. The spools you can get at the hardware stores is made to be used in walls and whatnot, so the wire is solid core wire. Patch cables are made to go from the wall to your device, so they are stranded wires. Stranded wires will take the continuous bending much better than solid wires. Eventually the solid wires with work harden and break, causing intermittant issues. The only issue with this is stranded wires won’t punch down as nice in the network keystones.February 24, 2016 at 3:34 pm #8222
Thanks! Thats a very good point about the stranded vs solid core I didnt know about.March 10, 2016 at 1:46 am #8827
I have the MPCNC machine finally assembled and found out that I forgot to order the wiring kit with my bundle, which brought me to this tread. When Cat6 cables work fine maybe flat retractable ones (see picture) could be used for bigger machines as well, to keep everything clean and neat. I will order the regular wiring kit for this set up (30×30) and finish the table in the mean time, since it is standing on a cardboard box. But on my next set up (4×6 or 4×8) I would like to use retractable cat6 cables installed in the middle underneath each x and y axis if possible. For the z axis I don’t know yet where the best location would be, but I will figure that out along the way. Can that work, or would the pull (although little) from the retractable cat6 holder be counterproductive?

Im using RJ45 connectors and my laser works amazingly well.
It wont work for your D660 of course
Anyway, im running 22 gauge from laser to RJ45 jack, then 18 gauge to the board.March 10, 2016 at 8:16 am #8848
That retractable one would look so slick! They do tend to be very small wires in there but if it works it would be awesome. gives me an idea……March 10, 2016 at 11:00 am #8861
Those “Recoil” winders can also be used with other kinds of wires as well and are very cheap too (about 2-3 bucks each). They might need some modifications to work as intended, but whats a 3d printer for? And you could brand them “vicious”. Maybe we can even design our own version when we can find suitable springs.
