Welcome to the SeeMeCNC Community

So a quick google turned up Polygonhell's post on replacement fuses: http://forum.seemecnc.com/viewtopic.php ... 4209#p4209

You can replace these with 10A fuses. I have 5 on the way! I am planning to run 2 extruders so I'll need these.

that'll work too. =)

thanks.

It's for all of the Mosfet outputs except the heated bed.
I think you'd blow the fuse running 2 standard SeeMeCNC hotends, they draw almost 2x the current most resistor based reprap hotends do, since they use more or less the same heating resistor but 2 of them in parallel.
You can replace it with a 10A fuse according to the Rambo design docs, and probably you could get away with 15A.
