Re: MK2 Heat Bed Wiring- stand alone

Well, I don't exactly have anything 'stand alone' operational or even close, just a group of parts. If I go the mega+ramps route, will that run separately from my Cubex board or would that completely replace it? Ideally, I'd like to have it run separately, but if replacing the board is as easy as unplugging the motors/hotends/sensors/etc and plugging them back into the new one, I'd entertain that plan. Here's an example of a unit that has the temp set independently from the gcode file [shop.grmproducts.com], although it's super expensive.

I've done searches for this type of thing, or even a sensible wiring diagram, and I've turned up with very little. Does anyone know of a good blog/post that explains some options or methods for a heated bed without running through the main printer board?

Thanks for the help,
