MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
The control PCB is located half underneath the bed at the back of the machine. It is cooled together with my raspberry pi kind of indirectly by a gigantic Noctua fan.
Some pros and cons:
As an extra for repurposing an ATX power supply, as that's the other sort of unique thing about my implementation:
1) the LED strips actually serve to apply a load on the 5V rail of the PSU: without them, the thing goes into shut down the moment you draw current at 24V from it.
2) A non-modular PSU tends to have a cable management sleeve built into it. If you are willing to commit, you can steal it and use it for the X carriage wiring while cutting off and potentially sealing the rest of the cables you are not using. It is a good idea to keep several cables of each voltage around though, in particular, 2-3 wires for the 5V configuration. Strapping them together keeps the cables from overheating. For others, you will need power for a bunch of stuff (like that Noctua fan!) so you might as well use the cables that already come from the PSU.
