Post Body

Some mates and I are building a larger reprap (based on a wilson 2) and we are using multiple (4) heated beds.

I was thinking of using a prototyping shield similar to this: https://cdn.sparkfun.com//assets/parts/2/9/1/0/09346-1a.jpg

And replicating the mosfet circuit from the ramps board to control each of the heated beds. Each bed should max at 11A so I will likely need to use a separate supply than the 12v on the ramps.

I am keen to still use PWM if possible, otherwise I would just hook up D8 to a relay and go with a bang-bang style approach.

Any thoughts or suggestions for another way to approach this?
