If you install a 5i25, you can use the amd64 rt-preempt kernel and install you are already running. The 5i25 provides hardware step generation, so the interrupt latency and jitter requirements are vastly reduced and an rt-preempt kernel works just fine. If you want to use software stepgen, your best bet is to use the RTAI kernel which means using LinuxCNC and you should just install from their live-CD. As an alternative, if you can find (or build) a Xenomai kernel for your current install, that should work /almost/ as well as RTAI and should be suitable for software stepgen if you do not need an extremely fast base thread. The rt-preempt kernels are not suitable for software stepgen, at least for now. -- Charles Steinkuehler [email protected] -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
