EMC2 running on Raspberry Pi?

I am not trying to be a buzzkill, but when you can use a ready-to-go version of LinuxCNC on the stock beaglebone black, which is noticeably faster than the Pi, why even bother?

One way would be to do it and simply not fund it. ie just treat it as a hobby, and give away the results. Like cross-stitch, except nobody wants cross-stitch.

Mungkie, perhaps the lack of an interest in financing is because the RPI + LinuxCNC is limited and does not arouse the interest for commercial use. So, it is preferable go to BBB or X86 PC. This work with RPi is very important to the community. I think to call attention the board should be better than BBB.

For sample,

I am walking with ODROID-U3 + LinuxCNC + RT Kernel as a hobby. I'm using version 1 without SPI and I can say that is very close to a conventional computer (around 1.2GB of memory with full load of CPU quadr-core during a convertion: 20 seconds on Odroid and 15 minutes on RPI to convert image to Gcode) At the moment I just need hal SPI driver (the maintainer of hardkernel / ODROID released version 2 of ODROID-U3 with SPI pins, they are very understandable, I'm hoping my buy).

I'm not saying to change the board, just my point of view across your comment.

Best Regards Mungkie

I haven't read the thread but this seems a better board than rp and bb
check it cubieboard.org/2014/05/04/cubietech-will...performance-mini-pc/

I am going to start a kickstarter project within the next couple of weeks unless something unforeseen happens.

I have pretty much finalised all the parts, and should be trying to get enough volume to place an order for parts that will allow a little profit to allow me to pay for some test equipment to get the gpio input driver sorted out, should be that a 5 axis kit suitable for micro mill/lathe or 3dprinter will cost £100.

Why? Machinekit already runs on the Beagle Bone, which has much more GPIO plus the
PRU processors to vastly accelerate step generation and other tasks. It works very well
for CNC motion control.
