I was thinking of a base board to replace the Due, and reuse the RAMPS-FD, or RADDS, or perhaps Decapede?
Although the modular approach requires some compromises, having to respin the stepper drivers, mosfets, thermistor is time consuming, and it allows to concentrate on just the CPU board. I also figure the field is quite well served with all in one ARM boards, R2C2, Smoothieboards, 4pi, Duet.
However, I have an open mind at this stage, especially if collaboration is involved to share workload, my timescale is "2014" so it's quite relaxed :)
I also noticed today while I should have been working, that Freescale have "Vybrid" VF3 series, which has Cortex A5 266MHz, double precision FPU, 1.5MB on board RAM, in a 176 LQFP, I think it requires external Flash. Farnell have them listed at £11 singles.
