I suggest that if any RPC is recommended the printer likely has a degree of 'power conditioning' built in. (& that's a good thing)
If you build an RPC (w/cheap 3PH motor from CL or EB) I strongly recommend PhaseCraft for the control panel. Their setup help and service after sale are among the best out there. Lots to read here at the bottom of the page. (Not just pitch)

Some general tidbits about phase conversion:
- Phase Perfect doesn't require an idler but it isn't exactly silent. (not too bad, tho')
- an RPC's idler/motor typically runs 'louder' than if used as a load motor with 3PH from the pole.
- At 20hp rating, consider building a 'doghouse' for an RPC (often outside the shop/office) as noise may drown out that of what's running on it. (not so good)
btw. Counting on seeing pics of the printer/output someday.
