Some more electrical. The legend plates came out real nice in the Epilog Zing at work:

Hi
I love the speed adj, legend plate, the + & -, great job.
Does the 0 line up with the motors 60 Hz running speed, or 50 Hz. ???
If not can it be adjusted.

The VFD can be programmed to any range. My plan is to set the range to ±50%, from 30Hz–90Hz, so 0 on the dial gives 60Hz and the speed shown on the gear box.

Easy enough to engrave a new plate if that range doesn't work out, though. It's stuck on with some VHB transfer adhesive, but that will come off with a heat gun.

Added terminal blocks, relay, and wire ducts today.

Also got the cord ready. I wasn't expecting the plug to be quite that big:

Looking good. Smart move to fasten everything to a back plate rather then trying to wire it up inside the bottom of an enclosure. Looks way more professional as well.

I generally prefer to use L6-30 twist lock plugs for everything. Not nearly as huge.

That is a huge plug! Who makes that?

It's a Hubbell NEMA 14-30. Hubbell's plugs are very solid: nylon block, set screw cage clamps on the conductors, and beefy strain reliefs.

The backplate and mounts came with the enclosure, which made the decision pretty easy :)

The NEMA 6 stuff doesn't have a neutral :-(. The L14-30 would have been cheaper, but I didn't think to have the electrician install that on the lathe outlet. I did have him put an L14-20 on the opposite wall for an eventual mill install.
 
My lathe has a 240-120V transformer in it, so I didn't need a neutral. My lathe uses 120v for control power.

What are you using 120V for? DRO?

Looking at your schematics, I don't actually see your neutral wire going anywhere except maybe "Power Feed"? what is that?
