I just cut mine and spliced in the correct length of wire. There are two advantages… 1. you will end up with the correct length of cable. The C3D extensions are way too long. 2. You won’t have sharp edged connectors rubbing on your other cables in the cable track. Something to think about anyway…
When I ran my router power and the remote speed control and light wires through the cable track I had to get rid of the cable extension connectors to fit everything into the second cable track. It was easy to do and I feel better knowing that I don’t have any sharp edges rubbing other wires every time the cable track moves.
Tony, What gauge of wire did you use for your motor extensions? I think I’m going the splice route myself. The extension cables CM3 sent with my XXL upgrade were just about the right length, except for the right Y motor. That one barely makes it.
Thanks. I found the recommended wire for the cable extensions is 18-4 shielded security wire. They sell that at Home Depot, so I’m going to pick some up. I saw your comment regarding removing links from the drag chain in another thread. The drag chain that came with my upgrade seems to be just about right. Maybe they corrected the length they are shipping out? I connected one end right about at the end of where the controller cover sits (from the rear), and when fully extended, the drag chain does not flop out over the front of the machine. So I think the length is about right. I think I just got one cable that is a little short. Of course I never measured it before, and I’d have to pull it out and take all the covers off again to get to it. So I think I’ll just extend the one a little and be done with it.
My stepper extensions had plenty of slack for my XXL. I did take some liberties in dressing my gantry wiring, specifically mounting a wiremold track so I didn’t have to look at wires. This did require that I nip off the Molex orientation guides, however a few sharpie marks to ensure orientation should they ever need disconnecting and the extension cable now fits nicely in the track.
Wiremold. Bought it at Home Depot to disguise all my CAT-6 cabling and SAT coax on the outside of the house. I had a few sticks left over and figured why not hide all the wires. My Y limit and YR motor cables are enclosed in the track.
