Nik. yes I'd be interested in that, although I am ATM, down one of my 
other machines & have about 75% of the stuff ordered to put the two 
BoB's in a separate box with hopefully better psu's. A $3 buck regulator 
died a horrible death, spitting epoxy off the top of the chip, and 
putting 35 volts on the 5 volt BoB supply buss for the few millisecs of 
the death throes.  But the big lathe, running on an r-pi-3b is working 
well. But any improvements in latency would be appreciated. .075 
milliseconds on the servo-thread is tolerable, but its pretty wide in 
terms of following error.

I've 32Gb sd's to put it on.

Cheers, Gene Heskett
