Re: [CAD_CAM_EDM_DRO] Strange lost step problem, grounding related

Jon,

I'm running 3 phase into the inverter.

Looking in Newark, I found the types of filters you referenced at C&H
but in 3 phase. A Schaffner low current model at 10 amps is $88.
Yikes!
Well, mounting the inverter on the wall has all but eliminated the
problem. That is, reduced it to a level I can live with for now.
I think I'll need to evaluate what further projects I'm going to be
putting inverters on. For just under $300, I could get a unit that would
cover everything I might ever try to run in my shop, but I'd have to
rewire things to get all lines feeding the inverters to the filter in as
short a distance as possible without crossing something else.

Thanks much for your help!
