Not realtime at all, or are you running preempt-rt? There are several options: Linuxcnc-uspace on a standard kernel - OK for sim, not for motion control Linuxcnc-uspace on the preempt-rt kernel - Good enough for most purposes. Especially with FPGA cards, and the only option for Ethernet Mesa cards. Linuxcnc-RT on the RTAI kernel - Gives the best latency, generally. But that isn't always needed. Linuxcnc-uspace on the RTAI kernel - needs the linuxcnc-uspace-rtai deb installed, works pretty well running RTAI with LXRT - May work with ethernet mese Linuxcnc-uspace on the Xenomai kernel - needs linuxcnc-uspace-xenomai to run with LXRT - I have not tested this To install the preempt-rt kernel there is no need to compile anything. Just sudo apt-get install linux-image-rt-amd64 and then reboot. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
