Why don't you start a new thread with an actual question. If you have problems with interference, you will get a better response if you detail the issues and ask for advice. I am sure that Lee would agree that this is the best approach to take. If he doesn't, he will voice his disagreement and correct my assumptions.

The gist of this thread was to encourage CNC builders to keep wiring neat, properly earthed and appropriately shielded. Yes, shielded wiring to the steppers will be a good thing, but should really not be necessary if your control electronics are properly designed and installed. VFD's and steppers produce EMI, but it ought not to interfere with anything in a grounded metal control box.

You will find members of this forum knowledgeable and willing to help and although some take the piss a little, the forum is generally friendly and you get good advice.

I am the joker in the pack
