BTW, did someone else (than Zultron) try to use the core isolation feature to "turn on" back the step signal generation in software? My electrotrash which I use for Machinekitdoes not have cores to spare.
And Elephant period is nice name. The servo period was always problematic name - maily because when one say "servo" most people think of AC PMSM, maybe some driver. C.
