Another Mill - Haas, Another Tormach, or a Novakon?

All of our 3ph equipment at work requires Delta (3 legs of 120v). I've worked on some outside of the PO and had to buy a transformer to convert the Wye to Delta in the building I was in.

That's going to up your costs if you have to replace all the drives.

His machine simply requires 3-phase @208-240, it contains all the necessary transformers to provide proper voltage to it's systems.. He's set with the RPC he purchased..

LOL!!!! Somehow I missed getting updates for most of the last page........and I'm so far behind in watching youtube vids that I hadn't seen Brad's vids either. I'm now caught up and understand what's going on!! LOL Have you read my signature?

So the Fanuc Alpha Drivers want 208-230 and my Rotary put out 240-250-240 - So I pulled a capacitor and it's now all about 240, so I just purchased a buck boost transformer to drop it down below 230. Reason is right now my servo's are LOUD, and I read it's from to high voltage, so I'll keep it off until I get it re-wired with the new x-former. It being summer the voltages are low in Iowa, but come Winter I don't want them to spike up and ruin anything.

Here is a video of the lathe.

That's like finding change under the back seat of the used car you buy.
