Do you have steppers with software step generation? If so, calculate base_period according to your measured max latency, your step driver timings and required step rate in Hz. The same goes for software PWM generation or encoder counting, if you're doing those things. Otherwise, do not use a base

thanks for the answer Jeff,, now, how do we calculate base_period and servo period? Jeff Epler writes: > > The latency-test runs the following realtime component: > http://git.linuxcnc.org/gitweb?p=emc2.git;a=blob;f=src/hal/components/timedelta.comp > > Each time a realtime thread runs, the ti
