If that offending light was on your Powermatic lathe, why didn't that EMI shut down your lathe? You participate in a lot of forums John, when is the last time someone had a VFD controlled machine shut down due to EMI? A lot of praise for Laguna's new line of lathes, but poor Edward is the only one in the forums to have this issue at his residence. I'm very skeptical about that answer and that diagnosis from the manufacturer is horse pucky in my opinion. Now I know that the VFD can cause EMI issues with other electronics, but the manufacturer said it was EMI in his residence. A friend had to remotely locate his VFD that controlled a CNC spindle, because the manufacture of the CNC machine claimed there was interference creating lost steps in the stepper motor controllers. Shielded cable should resolve that issue, so don't know if the machine manufacturer failed to do that, or didn't ground the shielded cable properly. Now if they tell Edward to remotely locate his VFD, then I would understand and have faith that could be an issue. But no one else has reported issues on the Laguna lathes.
