With the IGUS power cable:

1) Did that feed through the rubber strain relief at the body of the router, did you remove the strain relief or something else?

2) Should the outer shielding of the cable be connected to the ground pin of the plug (that would require changing to a 3 prong plug)?

edit: I took the top off of my Dewalt DW611. It's pretty easy/straightforward. The "rubber" strain relief "boot" is independent of the cord, not glued together and not glued to the body of the tool. It should be no problem to feed a new, similar diameter cord through it. But because the existing cord doesn't have a separate ground wire (only hot/neutral), I wouldn't be sure what to do with the ground at the tool end - maybe just cut it off where the cord is clamped in place?

I saw the problem as one that probably needed more than just one level of interference protection. I started with ferrite cores on every cable, added a noise isolation surge protector http://www.tripplite.com/surge-protecto ... ULTRABLOK/ and finished it off with a shielded power cable (CF6-07-03) http://www.igus.com/iPro/iPro_01_0013_0 ... ?c=US&l=en to the router (IGUS sells by the foot). The major difference was seen after adding the shielded power cable. No more disconnects AT ALL, even on a 10 ft USB cable.
Hi CCSnell,
Like so many others, I've also been dealing with dropped USB connection. The Igus power cord sounds like an interesting option. Could you please go into a little more detail with how you connected the cord to the router as well as clamping on a plug? Does one need to buy a 3 prong plug, or just a 2 prong plug? The link you provided has 4 conductors, I'm not sure how these all get connected.

Thanks for your help!
Dave

I have ferrite on my power cable and on both ends of my USB cable.

STILL getting the disconnect- sometimes in the middle of projects even without turning the router on and off.

They seriously need a board fix of some kind.

Please contact support@carbide3d.com w/ the details of your setup and any specifics you can share — they can’t improve the board if they don’t have all possible information.

Ive gotten requests to further clarify my wiring. I attached the ground cable at both the outlet (3 Prong Plug) and inside of an aluminum control box attached to my machine. The box is for my spindle control unit (SuperPID V2). Then I continued using the shielded control cable (IGUS Shielded 3 conductor with Ground) to run to the spindle (Dewalt DW612), I also dissasembled my spindle housing to wire it for speed control and applied a conductive shielded spray paint (MG Chemicals Super Shield) to the plastic sections of the body (while they were COMPLETELY detached from the router, you don't want conductive spray paint going inside the motor.) I also attached ferrite cores on all cables. As long as you have the control cable grounded at the outlet the EMI can be contained and sunk to ground (or so goes my understanding of EMI from googling the hell out of it.

Hi CCSnell!
Thanks for clarifying. My setup is a little different than yours, as I am not currently looking to add spindle control. However, your posts will prove helpful I believe, as I just want to eliminate EMI. There is one thing that I am still a little unclear with the shielded wire, and that is what to do with the shield inside the router.
So, in an actual question, does the shield get connected to anything inside the router, or is it only the outlet end that gets connected to ground?
I read through a couple of the links you provided, and understand the need to connect the shield to ground on one side to act as a drain, but am unclear if the shield needs to be attached or free inside the router.
Thanks again for your insight.
