Re: question about using a 24v heat bed

That heat bed has a resistance of 2.4 ohms, so it will draw 10A @ 24V. I suggest a 14A fuse.

RAMPS is not ideal for 24V systems, because most RAMPS boards have 16V capacitors. But this doesn't stop you using a 24V supply for the heated bed only, and a 12V supply for everything else. Both my printers use Duet electronics, which can go up to almost 35V.
