For now I'm using it via halcmd. I had really high jitter when I run latency test with Debian Stretch. So I installed Wheezy with LinuxCNC 2.7.14
I'm running latency test right now with several instances of glxgears running and I get a max jitter of 70000 ns on servo thread and 79000 on base thread. But I've only been running it for 10 minutes or so. I plan to leave like that a couple of hours to see if there's something strange. The funny thing is, sometimes the board starts working ok and the problem starts when I stop the thread and try to start it again. El sáb., 7 mar. 2020 a las 22:00, Peter C.
