#linuxcnc-devel | Logs for 2015-07-30

[07:58:03] <jepler> (queue busters being some other semi-baked idea from that guy)
[09:24:15] <mozmck> alog
[09:24:19] <mozmck> oops
[09:24:20] <mozmck> zlog
[09:52:41] <pcw_home> Something has gotten better! with the jepler/hm2-eth-startup branch
[09:52:42] <pcw_home> I can now start linuxcnc at 4 KHz on my home desktop (C2D 8500) without error (this barely ever worked before)
[09:52:44] <pcw_home> and... it been running at 4 KHz all night with youtube videos playing which it also did not do before
[09:52:45] <pcw_home> (This part may be related to the kernel which I updated to 4.1.3-rt3)
[09:53:58] <pcw_home> (running a single 7I76E 4 axis setup)
[09:56:47] <skunkworks> awesome
[10:04:31] <pcw_home> maximum servo thread time = 150 usec
[10:07:56] <skunkworks> wow
[10:08:18] <skunkworks> it is always nice to have jepler touch things...
[10:08:20] <skunkworks> ;)
[10:08:51] <skunkworks> and he said each device added about 90us
[10:08:55] <skunkworks> or so
[10:10:06] <pcw_home> so 4 devices should be easy at 1 KHz on many CPUs
[10:10:37] <pcw_home> I get less per card overhead but may have a faster CPU
[10:13:54] <skunkworks> sure
[10:14:33] <pcw_home> I'll have to try the 4.1.3-rt3 kernel on the J1800
[10:14:39] <skunkworks> my heart stopped for a second when threading didn't work on robs new branch (graphing for tom) but I was in the wrong repository
[10:14:59] <skunkworks> I am running on a j1900 I think.
[10:15:53] <pcw_home> Linxcnc order up, please hold the bugs
[10:16:57] <skunkworks> and that is how rigid tapping is done - booya!
[10:16:57] <skunkworks> http://linuxcnc.org/index.php/english/forum/40-subroutines-and-ngcgui/29451-rigid-tapping-fail-advice-and-qdiscriminantq-err?start=20#61041
[10:17:17] <pcw_home> glad you answered tome with a correct plot
[10:17:56] <seb_kuzminsky> skunkworks: do you know the state of rob's feature/tangent-improvement-2.7?
[10:18:22] <seb_kuzminsky> last i heard rob wanted to document and maybe rename "kink ratio"
[10:18:38] <skunkworks> I have found some slight overages (at the most 3%) that he hopes to look at. (I think it is shipable...)
[10:19:05] <skunkworks> and yes - he needs to document/rename the kink ratio setting.
[10:19:36] <skunkworks> I can email him and see what he thinks. He was gone over the weekend.
[10:20:22] <seb_kuzminsky> ok, cc me please
[10:25:29] <seb_kuzminsky> haha, bug #428
[15:53:54] <archivist> looking at his encoder, I would also just add another opto (adjustable for best angle)
[16:56:13] <jepler> doo de doo
[16:56:19] <jepler> people looking for stupid little bugs = win
[16:59:58] <jepler> knowing it's been there unnoticed for 7 years must be why he included the blame output
[17:08:47] <seb_kuzminsky> it's actually a really terrible bug, on architectures where s32 and u32 are different size
[17:13:18] <jepler> you been testing on one of those/
[17:14:03] <jepler> "By using -1+i as the base, all complex integers (numbers with integral real and imaginary parts) can be expressed as a ginel "number" without any explicit sign or other irregularity [using only 0 and 1 for digits]"
[17:14:13] <jepler> ginel = single

[19:25:35] <skunkworks> could that test you made be run on machine kit for the douplicate oword?
[21:08:36] <jepler> someone said it works on 2.6 so it's likely to work on machinekit. and by work I off course mean fail...
[21:36:01] <jepler> iteration 79904
[21:36:21] <jepler> that's iterations successfully loading an ethernet-using config, without error, until I stopped it
