OK being an ex mechanic and a crafty bugger, I have shielded the original spindle cable and run it separately from the rest. I have also earthed all bodies.

Let's see how it fairs. Its running a program now its always struggled with. Lego block lol.

Anyway after reading and thinking about what you said it dawned on me. Yes before I was running spindle speeds above 5000 rpm there wasn't much current so little interference, since its been running upto and beyond 15000 rpm that's when it started going haywire.

Let's see if my DIY shielding worked
