Cube 3D printer community

@spegelius, I don't know much about power supplies other than voltage. What else should I be looking for to make sure that it will able to run my hotend and an additionally heated bed?

After you help me figure out which power supply I need from ebay, I'll be adding it to my order of terminal crimps and ramps board.

I'm hoping to start on this project before the end of the month depending on when everything gets here from China.

Anything else you can thing of that I might need so everything can arrive on time? Anything I can to prepare while I'm waiting for the parts to come.

Thanks again for all you help. If we can get this up and running I will be so happy. Next I'll just have to get better at 3D Modeling.

So Excited to make this happen. 

If you don't have ATX power supply to use, something like this would be a good choice: http://www.ebay.co.uk/itm/DC-5-12-24V-Universal-Regulated-Switching-Power-Supply-for-LED-Strip-3D-Printer-/111544566393?var=&hash=item19f8930279:m:mgXbKNkedYP0vXZS6rgAhtw. Select at least 200W model if you are going to be using heated bed. If not, 100W or 150W should do fine. Do a search for '12V power supply' in Amazon or Ebay, there's lot's of options for brands. Needles to say, the cheaper ones might not be as robust as the more expensive (better) brands.
I don't have any experience of that type of power supply, i've used ATX type because i have some old ones that I put to use.  But i've seen them being used in 3D printers and basically any 12V power supply will do as long as it outputs enough power.
Also with ATX power supply there's the option of turning the power supply on and off in Marlin, but I haven't used that system yet.

For other bits on bobs: I suggest ordering a RepRapDiscount Full LCD controller with the RAMPS. Has SD card slot so printer can be used without PC. Shouldn't cost much, i think i got a RAMPS+Full LCD less than 50eur last time i ordered from Amazon...

Other stuff:  I have a good set of assorted tools that I use when fixing stuff etc. so it's hard to say exactly what to buy. But generally if you have hw store nearby and find that you need some tool, then it won't be a problem.

If you can print parts now, wouldn't hurt printing them beforehand. These are what i've printed (not necessarily for Cube, i've got other printer projects going on):

There's also some parts i've designed myself, i'll post them someday...
