I always disable hyperthreading first thing. This morning after running for
about 20 hours I have:
Max Jitter
Servo Thread: 22532
Base Thread: 31206
Much more reasonable. The only things done are turning off hyperthreading and
setting isolcpus=1 in the kernel.
Thanks for the help,

Did you do the standard things, SMI, legacy usb, video driver, etc? There

I have a DN2800MT Atom motherboard that I want to run Linuxcnc on. I am using
a Mesa 6I25 for step/dir so I am not much worried about latency. I know this

or so which was fine. I did that with an older version of
