Hi, just trying to work out what power supply to use for the 12" i3v. Has anybody taken current readings from their setup?

In particular, I would be interested in the current draw of the bed vs the total draw. I get a feeling that a 30A supply would be nearing its limit, and I may be better off either with a 40A supply, or a 30A supply dedicated to the bed and a ??A supply for the rest of the printer.
