    What's the heated bed rated at? I need to decide if I'm using the mosfet on my board or a SSR for it. Being multizone will I need multiple power inputs or are they just controlled separate?

    It's rated at 400w, 24v. See also this blog.

    @Rob Heinzonly Actually the 400w number comes from the BigBox's power supply rating - the heated bed itself draws ~10 amps at 24v, so right around 240w.

    @sithrebel15 The VariPower heated bed has a heat density that varies across the bed adding more heat at the edges, but it does not have multiple independently controlled zones - all one zone, one connection.
