I dont think the smooth stepper handles acceleration, basically its a rate generator just like the 7I43s stepgen. Acceleration management is not needed in the low level hardware unless you have quite slow update rates (say less than 1 KHz) Acceleration would be easy to add to 7I43s stepgen but with EMCs 1KHz update rate the accuracy gains are miniscule and the overhead of the additional register access would be substantial. > > Cheers, > -Neil. > > > > Quoting andy pugh <bodge...@gmail.com>: > >> On 30 June 2011 16:13, Neil <emc_d...@narwani.org> wrote: >> >>> So the Mesa looks like a breakout card of sorts. >> >> It's rather more than that.
