Multiple power source/multiple heater setup

All, I had asked some questions about non integrated heaters, and I think it is a bit too advanced for me right now.

I am trying to make a printer with a 500mm x 500mm print area, that can print ABS.

So obviously I need some serious heat for the bed.


Here is what I am thinking, and I wanted to see if I could get some feedback before I buy everything to do this.

My plan is to use two heaters:

24V 17A for the 11amp input to Ramps for the heated bed.

12V 20A for the 5amp input to Ramps for all else


I want to use somewhere between 2 and 4 24V kapton type heaters to the underside of a sheet of 500mm x 500mm aluminum sheet, which my glass will sit directly on top of, OR, I may just use a 6mm sheet of aluminum as my print bed.

I will use a blade fuse between the 24V PSU and the Ramps 11 amp input.

Does this sound like it will work?

Thanks!
