The Edison can't compete with the RasPi 3 by a long shot
I believe the bare edison module is (while being much weaker overall) even more expensive than the RasPi 3 (which is after all a complete board with connectors and power supply...).
The Edison mostly has one advantage over the Pi - it's a lot smaller. Great for IoT stuff, but I don't think it would be particularly useful to control a 3D printer - at least not in it's current state.
/edit:
Confirmed, the Edison module starts at about 55$ on mouser.com (with different versions available) while the RasPi 3 is still sitting at a beautiful 35$ selling price.
RADDS controller?

Re: RADDS controller?
Any 3D printers or CNC's use the Pi for a brain?

Re: RADDS controller?
Haven't heard of any. Like mentioned before, the Pi isn't suitable as a direct controller - because it doesn't have a real-time OS. Even my own platform will "only" use the Pi to shove the gcode data into the FPGA which is the actual real-time controller. (this is simplified of course. The Pi does in fact do more than just that, but it doesn't do any of the control tasks itself)

This thing really tries to do everything at the same time. Wonder when that's ever going to work well

Re: RADDS controller?
I actually see machinekit as very interesting as it is a fork of LinuxCNC that are rewriting stuff to be able to run on embedded systems and get better separation of backend/frontend.
To me most of the controller boards are totally uninteresting for CNC use, since i cannot hookup a monitor and a control panel, where i can see DRO, use MDI mode, preview my gcode etc. It also got a very nice hardware abstraction layer and a software PLC to program event chains for toolchangers, automatic tool measuring etc. Fire-and-forget does not work in the same way for a CNC mill as for a 3D Printer, i do not get people that just run GRBL on a arduino and run a gcode file without any feedback, that is scary stuff...

Re: RADDS controller?
True, I would never run a CNC on something as crude as a 3D printer controller
On that note - I'm going to use an EdingCNC controller for my CNC build (which may or may not be finished by the end of this year )

Re: RADDS controller?
*One year later*
Finally got that RADDS hooked up to a few motors and sensors because I want to try out my printhead prototype. Can't get the Repetier FW to compile yet (I hate Arduino), but maybe later this day...
