EMC2 running on Raspberry Pi?

Hi There!

Have anyone tried to run LinuxCNC on a "Raspberry Pi" computer?

Short answer is no, the main thrust of LinuxCNC is still running NC machines on inexpensive computers, rather than trying to create embedded systems or find a way of using restricted low power boards.

regards

although not an up to date version of Linuxcnc , heres a starter project using a webserver interface , but needs work
if you have the knowledge.. .

While I don't want to dismiss the LinuxCNC projects goals do realize that these single board computers are getting more powerful everyday. The are indeed inexpensive too, especially if your intentions are to buy new hardware. There may not be an ideal board out there yet, but that could easily change, further I/O is far easier on some of these boards.

The flip side of this is that consumer grade PC hardware is going in a direction that is not friendly to machine control. In this regards we are already seeing issues at work where PC hardware for industrial use is getting more expensive. You can read that to mean PC hardware with lots of slots.

So what I'm saying is that it might not be a bad idea to keep an eye on the embedded processor board world. Linux is becoming very common place there and I really don't think it will be too long before suitable embedded boards are actually cheaper than some of the new PCs being used. Recycled is likely to be always cheaper but that is a different story.

I am sure it will run eventually if someone put enough effort into it

I have got the linuxcnc RT_PREEMPT fork to compile and run in sim mode, but, I am currently looking at hardware interfacing and writing a IO driver for loading into the hal as I feel the kernel will get sorted by someone else.

The interface should cost around £3 in components to build and give 16 bits of IO with 50kHz switching (if the PI can switch it that fast??).

I am still really in the guessing and rough testing stage though so I may never complete things if I hit some unforeseen obstacle.

I will eventually try and hack a kernel with real time support but am leaving it for now as I know absolutely nothing about real time kernel compilation and think an expert would do it quicker and better than I ever could.

Still waiting for mine to arrive <sulk>
