02:15 AM linuxcnc-build_: I'll give a shout when the build finishes
03:51 AM linuxcnc-build_: Hey! build 0000.checkin #4943 is complete: Success [3build successful]
03:51 AM linuxcnc-build_: Build details are at http://buildbot.linuxcnc.org/buildbot/builders/0000.checkin/builds/4943
04:55 AM emcPT: I am stuck at a midle of a job and I require some help. Should be simple.
04:55 AM emcPT: I have upload a image to https://ibb.co/hShyqk
04:55 AM emcPT: The problem is:
04:56 AM emcPT: I am making a internal thread
04:56 AM emcPT: and the tool is almost the size of the inside hole
04:56 AM emcPT: but it can machine the thread
04:56 AM emcPT: The problem is that the G76 cycle is retracting too much the tool
04:57 AM emcPT: and it does not respect the "I" value of the G76 cycle as described here: http://linuxcnc.org/docs/2.6/html/gcode/gcode.html#sec:G76-Threading-Canned
04:58 AM emcPT: For me, it makes sense that the retraction is always done to the same X value
04:58 AM emcPT: (X=diameter)
04:59 AM emcPT: The G76 used is on the image
04:59 AM emcPT: Any ideias?
05:21 AM emcPT: well I am making it with G33, but I still think that something is wrong with the G76
07:46 AM skunkworks: jepler, changing the video driver fixed my laptop - Would that fix the forum?
07:46 AM skunkworks: ;)
07:46 AM jepler: skunkworks: I'll do that right away
07:54 AM jepler: emcPT: as shown below, the tool doesn't return to the original "drive line" each time. Instead, it returns to different locations so that the entry move (green vertical move at right) always has the same length. I believe this helps ensure that the start of the thread is uniform; if the line changed lengths, then the uniformity at the start of the thread suffers.
07:54 AM jepler: emcPT: as you have identified, you have a need that is not served by G76, so you are right to choose G33.
07:55 AM jepler: (also I think the exit move is also made to be the same length every time)
07:55 AM jepler: The documentation could be improved, but based on the information at hand I think G76 is behaving as designed.
08:22 AM jepler: all that said, it's possible that there is a bug. If you still think there is, you should make a simple standalone gcode program like the one in our source tree at tests/interp/g76/g76only.ngc that you believe shows the problem, and open a bug report on github.
08:23 AM jepler: the existing test uses a negative i value for outside threads, so the positive i value for inside threads is not tested.
08:41 AM emcPT: the i positive and negative works. I use it very often and it works fine.I think that for obvious reasons that the X of the retract should be always to the same spot (to avoid internal collisions). But it can also be possible that it is behaving like it should.
08:56 AM kwallace2: emcPT, I rewrote the G76 code for PathPilot to fix the retract problem that you mentioned. My documentation is here: http://www.wallacecompany.com/t_tmp/G76_doc/G76.html . Hmm, it looks like this may not be totally up to date. My last change was to not only retract to the same line but the line follows the main taper if called for. So in Figure 7 segment 4 would be parallel to 2. Figure 8 shows that end tapers still might interfere with tight ba
08:57 AM kwallace2: ... tight back clearance.
09:01 AM kwallace2: The slightly out of date source: http://www.wallacecompany.com/t_tmp/G76_doc/g76kw_interp_convert.cc
09:22 AM emcPT: Yes, it seams much better. Any reason why this is not on the linuxcnc dev?
09:47 AM seb_kuzminsky: i can not ssh to forum.linuxcnc.org, and i can not connect to its DO console, so i'm power cycling it
09:47 AM jepler: seb_kuzminsky: ugh thanks
09:49 AM seb_kuzminsky: geez DO, how long does it take to yank the power cord out of a VM?
09:49 AM jepler: it's usually pretty quick
09:50 AM seb_kuzminsky: it's coming back now
09:51 AM jepler: OFFS
09:51 AM seb_kuzminsky: the last entry in the memory monitor log shows it 3.7 GB into swap
09:51 AM jepler: with their new monitoring, the info doesn't survive a power cycle !?
09:51 AM jepler: the "graphs" page is just empty
09:51 AM seb_kuzminsky: there are many apaches
09:52 AM jepler: my change was supposed to limit it to 25 apache processes, if I understood things right
09:52 AM seb_kuzminsky: 1 gig of mysqld
09:52 AM jepler: 75 apache2 processes
09:53 AM seb_kuzminsky: yeah, that agrees with the ps listing
09:53 AM jepler: no I mean that's how many I counted in the list
09:53 AM seb_kuzminsky: oh
09:53 AM jepler: but I thought I set the limit to 25
09:53 AM seb_kuzminsky: yeah me too
09:53 AM jepler: .. fresh after reboot mysql is VSZ 880772 RSS 90700
09:53 AM jepler: so I'm not sure how much attention to pay to its VSZ having grown modestly to 901520
09:55 AM jepler: ./conf-enabled/local.conf:MaxRequestWorkers 75
09:55 AM jepler: OK this 75 does match something I've configured apparently
09:56 AM jepler: the great thing about apache is... you can configure it so much
09:57 AM seb_kuzminsky: heh yeah
09:57 AM jepler: OK maybe it's actually restarted with a limit of 25 workers
09:57 AM seb_kuzminsky: 75 * 400MB >> 1 GB + 6 GB
09:59 AM jepler: I don't know how much to believe VSZ numbers
10:02 AM seb_kuzminsky: yeah, much of that should be shared, and at least some of it not paged in
10:03 AM seb_kuzminsky: between 19:25:30 and 19:26:30 the system added a ton of apache processes, and that's also when the last entry was written to access.log
10:04 AM seb_kuzminsky: the machine stayed up until 19:51, but then "locked up"
10:05 AM jepler: 127.0.0.1 - - [09/May/2017:19:25:36 -0400] "GET /media/kunena/attachments/22936/C10-C41-KBIC120.jpg HTTP/1.0" 200 620202 "-" "-"
10:06 AM jepler: I wonder why the machine requests its own images
10:06 AM seb_kuzminsky: yeah, many of the connections during that time are internal, to attachment urls
10:07 AM seb_kuzminsky: i dont know if that's normal or not
10:07 AM jepler: 127.0.0.1 - - [07/May/2017:06:44:54 -0400] "GET /media/kunena/attachments/1749/Selection_002_2013-11-17.png HTTP/1.0" 200 74907 "-" "-"
10:08 AM seb_kuzminsky: the number of connections during the partial 19:2* 10-minute window doesn't look unusually high, compared to some other 10-minute windows leading up to there
10:13 AM jepler: it looks like because stupid, php/joomla will fetch an image via URL to determine its size
10:13 AM seb_kuzminsky: the number of connections from forum.linuxcnc.org and from 127.0.0.1 also seem about average just ebfore the crash
10:14 AM seb_kuzminsky: you reduced max workers and bounced apache? I'm tempted to restart the memory logger and walking away from this until the next crash
10:14 AM jepler: yes please start the memory logger
10:15 AM seb_kuzminsky: done
10:15 AM seb_kuzminsky: the old log i renamed to .0, the new log is accumulating now
10:15 AM seb_kuzminsky: bbl
10:17 AM jepler: digitalocean's alerts are useless, digitalocean's new stats reporting is useless
10:18 AM jepler: the new stats reporting requires userspace to be alive, so it never reached the sustained CPU usage threshold I set

10:37 AM kwallace2: emcPT, there hasn't been quite enough roundtoit to get the G76 update pushed over the finish line (polish the code, testing, docs).
10:50 AM emcPT: Thank you. I will take a look into it and ask you if I have questions during testing.
10:51 AM emcPT: The part that I was making is here: https://youtu.be/70HlJlqCvSA

11:15 AM emcPT: Too much stif
11:15 AM emcPT: Following error very,very low
11:15 AM emcPT: Like 0.02mm in rapids of 20000m/min
11:16 AM emcPT: " The sound is not from the thread, but the axis moving." this is, if I machine air, it will make the same noise
