[07:08:09] <jthornton> I've added a latency test launcher to a scratch branch and managed to get the Submakefile sorted out so the files get placed in the proper place and I can run the launcher from the /bin directory after building but after sudo make setuid if I try and run the command is not found. What am I missing?
[07:50:57] <jthornton> ~/emc/bin/latency from the home directory launches it
[09:38:21] <JT-JA13> teach-in.py still requires a nmlfile to be able to specify the text file to save to. Should that requirement be removed?

[10:57:47] <pcw_home> Got broadcast RX working for etherhm2, it was actually simple
[11:22:56] <Tom_itx> kewl
[11:25:31] <pcw_home> means that eventually multiple Ethernet cards could share the read request (need to add stored request packets)
[11:27:04] <pcw_home> PING 10.10.10.10 (10.10.10.10) 56(84) bytes of data.
[11:27:06] <pcw_home> 64 bytes from 10.10.10.10: icmp_seq=1 ttl=64 time=0.064 ms
[11:27:08] <pcw_home> PING 10.10.10.255 (10.10.10.255) 56(84) bytes of data.
[11:27:09] <pcw_home> 64 bytes from 10.10.10.10: icmp_seq=1 ttl=64 time=0.067 ms
[11:56:00] <jepler> it would be nice for detection too
[11:56:21] <jepler> just say what interface to hm2_eth, get all boards that respond to a broadcast read request configured automatically
[12:00:29] <jepler> not sure how often it would happen that any two boards would get the same read-request. they would have to have the same functions enabled, i.e., 4 stepgens on each
[12:07:59] <pcw_home> I was planning on adding stored LBP16 sequences
[12:21:41] <pcw_home> so a "interpret sequence #1" command could be broadcast and each device could do its thing
[18:05:52] <skunkworks> my intoxicated ladder didn't work as expected.
[18:06:10] <skunkworks> But I got it working with 2 timers - then just now got it working with 1 timer

[19:56:09] <skunkworks> still probably too complicated.. but works as needed

[20:08:35] <cradek> is this your first laddering?
[20:10:47] <skunkworks> no..
[20:11:54] <cradek> heh I didn't mean anything by the question
[20:12:23] <skunkworks> but I certainly don't have that much experience... :)
[20:59:48] <jepler> yay hm2_eth ran all weekend with .01% packet loss, pid stepper setup at 1200in/min
[21:00:20] <jepler> most of it using the idea of muxing the pid feedback value so that it gets command position when feedback is unavailable
[21:03:50] <skunkworks> awesome!!

[21:33:33] <jepler> I didn't get as far as testing with sserial and packet loss, let alone fixing it, this weekend :-/
[21:38:54] <skunkworks> i can update tomorrow
[21:38:59] <skunkworks> and tune it better
[22:16:27] <jepler> seb_kuzminsky: of all the easy options available, EMC_TASK_PLAN_SYNCH doesn't seem too terrible
