That's awesome. Unfortunately, I apparently won't have mine until september according to my supplier's expected ship date. I have been looking into the RTAI and EMC stuff in the interim. Both look to be do-able.

I'd hold my enthusiasm until you actually get RTAI and LinuxCNC installed, and actually run a latency check.

I don't think I will hold my enthusiasm. Without enthusiasm for such things we would not even have hobby CNC at all, and would still be cranking handles by hand. Or, at a minimum, we would still be running very basic CNC controllers on x86 based processors and just say that that is good enough. Enthusiasm has bred the types of controllers we have now with graphical representations of toolpath, with functionality that rivals even production based CNC controls.

If the miniemc2 project is any indication, it has already shown that it can be done on an ARM9 board. Although that project is still in development, all of the source is available and it is working using the GPIO of that board.

Obviously there is much work that needs to be done to make it happen on a RPi, but without enthusiasm it will never get there. I'll keep my enthusiasm high.

Notice I said "my" enthusiasm. Go for it. I'm anxious to see the results.

Unfortunately Linux kernel development is just one of the many subjects of which I find myself on the wrong end of the learning curve! Reading about it now.

I'll check out the miniemc2 project for pointers.

Yep, that's where I am at

Yep, that's where I am at

And are the results in?
