12" i3v Current Requirement

[printbus]

Sniffle, just to be clear - you only have the one power supply on your printer? It's good to know the heat bed is prewired with 12 gauge. I didn't know that.

TechMasterJoe had measured 29.7 amps on his, including I believe the cartridge heater and the motors being driven.

Thanks for the input. Also interested to learn that the 12" has 12 gauge prewired. I was planning on using 10 or 12 gauge for the high current paths anyway. 29.7A is pretty close to the limit, I am not sure how much one of the 30A LED power supplies is really capable of. I think I will go with a 40A p/s, that way I'll have a little to spare if more additions appear later on.
