Whats the 2 black box near your power supplies?
Your idea for the solenoids board are nice

The black boxes are power filters. Link

I wish I could take the credit, this is rodw's idea.

heh ... I think the guys over at the tube amp forum needed a break from me anyways.

I did not get as far a long today as I had hoped. I had a real case of the Mondays...

But heck, I only envisaged one of them. 16 amps should be heaps. Are you using 3 phase power? That would make sense.

Yeah, that is probably overkill. I assumed I should connect these power filters to incoming mains and then out to the Meanwell AC/DC converters... but now I wonder if I should put these power filters after the converters and run the DC power through them.

Yes, we have 120/208 wye.

I just used one of these so it protected everything. Mesa hardware, stepper drivers and all.

I found some noise was entering the control box via the mains ground wire but this killed it.

Bearing in mind I am no electronics expert but I think:

It would only make sense to use 3 if you were using 3 phases and spreading the load across those phases. This is how Lam Technologies suggest how you set up their drives (if using 3 phase).

I think you'll have to build two more machines now!
