[12:14:11] <crazyben> hi, looks like I found the root for my latency issue in the meantime. A process named "Ethercat-EoE" is consiming 97% of CPU. I disabled already all virtualisation technologies within the Bios
[12:15:49] <crazyben> Looks like this process is furthermore not terminated when closing the linuxcnc-gui. Within the shell I can see "A non vlocked signal was caught" after the gui closed.

[12:46:05] <jepler> I'll be taking a bit of a break from IRC. I'll continue to stay on top of forum updates, but I'll do my quick reboots without notice when necessary.

[12:50:09] <pcw_home> crazyben: (should you read this later) I would expect crazy behavior since your servo thread is running waaaay too fast
[12:54:03] <crazyben> pcw_home: Hi, what does that mean? .. Looks like I don't have the necessary background knowledge
[12:55:36] <pcw_home> the error message said the servo thread period was 100000 ns (= 10 KHz) 1 Khz would be more normal for this
[12:58:43] <crazyben> pcw_home : This can be adjusted as "BASE_PERIOD" and "SERVO_PERIOD" within INI-File, isn't it?
[12:59:02] <pcw_home> If you have a base thread, remove it
[12:59:32] <crazyben> What are common values for BASE_PERIOD / BASE_PERIOD ?
[13:00:36] <pcw_home> Not sure about thge EtherCAT driver but normally for external hardware (non-parallel port configs), base is not used at all and servo thread is 1KHz = 1000000 ns
[13:02:25] <crazyben> I have SERVO_PERIOD=1000000 and BASE_PERIOD=100000. Checked my hal-files in the meantime. Looks like the whole config is based on servo_threads
[13:03:05] <pcw_home> OK servo thread is right but somehow you have the base thread enabled
[13:03:44] <crazyben> I guess I may have some fragments of parallel-port config somewhere..
[13:08:45] <crazyben> nope, I don't see any link to an base_thread. To be honest, I did a new setup of my config a couple days ago. Everything was running on linuxcnc2.8 based on ubuntu.12.04 stable.
[13:09:04] <crazyben> pcw_home: this is the same laptop I used..
[13:09:45] <pcw_home> "Unexpected realtime delay on task 0 with period 100000"
[13:10:06] <pcw_home> i forget how you disbale the base thread maybe set to 0 period
[13:12:06] <pcw_home> on my (non base thread) configs the base thread period is simple omitted
[13:20:20] <pcw_home> (probably defaults to 0 = not used)
[13:29:37] <crazyben> pcw_home: I will come back to you tomorrow - I am totally exhausted today. Sorry & Good night all
