[00:34:24] <zhennanf_> Sebastian are you available now?
[01:04:41] <seb_kuzminsky> zhennanf_: hi jeff
[01:06:06] <cmorley1> mozmck: around for a few..
[01:11:55] <seb_kuzminsky> zhennanf_: i'm off to bed, i'll read back in the morning
[02:17:41] <zhennanf> OK have a good night :)
[02:19:25] <memfrob> re-writing dev branch of rtai (bored)
[02:19:52] <memfrob> little by little, one update at a time, i'll find the culprit....
[03:26:41] <memfrob> master branch is at 4.1 now
[06:39:01] <zhennanf> Hi, is there anyone available now to answer some questions about stepconf gui?
[06:40:11] <zhennanf> I'm currently consider serveral feature requests and bug reports relates to stepconf as my project for GSOC this year.
[06:43:59] <archivist> just ask the questions real in IRC
[06:44:51] <zhennanf> OK, for feature request ticket #60 I saw that the stepconf in version 2.6.7 already has an option for chosing unit between inch and mm what's the point of " Add an Unit (etc. Steps/mm) to BASE SCALE" ?
[06:45:44] <zhennanf> here is the link http://sourceforge.net/p/emc/feature-requests/60/
[06:51:10] <archivist> who added the feature to stepconf, could just be that someone did not updated the tracker
[06:55:09] <zhennanf> OK that make sense
[06:55:51] <zhennanf> Also does "pin motion.motion-inpos" relates to any part of stepconf gui/source code?
[06:58:48] <archivist> motion is part of linuxcnc and needs to be connected to
[07:06:03] <zhennanf> needs to be connected by stepconf?
[07:24:33] <archivist> possibly/likely
[07:36:25] <jepler> zhennanf: pin "motion.motion-inpos" was removed in 2009 by commit af317701.
[07:37:38] <archivist> which begs the question, are you looking at the right source version
[07:37:45] <jepler> zhennanf: please don't private message me. please discuss things in public.
[07:38:19] <archivist> more people can then help too
[07:38:42] <zhennanf> ops sorry I just wonder how you reply to me and hit the query to try
[07:39:40] <jepler> Is this a SF feature request you are discussing?
[07:40:08] <zhennanf> yes
[07:41:18] <zhennanf> but seems like it is abandoned for some reason long time ago and I just wonder wether I should add it into my project
[07:41:29] <jepler> I see that a source-code comment speculates that the pin might be useful to connect to an amplifier disable pin. Personally, I disagree with that because a motor driver will have some minimum delay between is "enable" input rising until the first motion request (e.g., first step pulse), and LinuxCNC does not provide that delay.
[07:42:08] <jepler> also, when disabling a stepper amplifier, the stepper loses position and in some machine configurations the associated axis may begin to move freely (for example, a Z axis)
[07:42:42] <jepler> I think that, particularly for steppers, the amplifiers *must* be left enabled at all times that LinuxCNC is in the 'machine on' state
[07:43:16] <jepler> anyway, just my opinion. I have to leave to go to $DAY_JOB.
[07:44:03] <archivist> I recommend never using that as well, steppers need full power to avoid losing position
[07:44:28] <zhennanf> Sounds like it requires more knowledge of embeded system, I will put this one aside
[07:45:09] <archivist> users think that a hot/warm stepper is a problem, it is not really
[07:48:56] <archivist> the comment he added "Add field for backslash compensation" makes more sense but users should avoid the need for it
[08:06:35] <skunkworks> zlog,
[08:07:52] <skunkworks> there is motion.in-position though...
[10:31:28] <zhennanf> anyone available to identify wether the feature request #112 already been added?
[10:31:49] <zhennanf> here is the link http://sourceforge.net/p/emc/feature-requests/112/
[10:32:53] <cradek> do you understand how to read a patch file? you can just look at the source and see whether those lines were added.
[10:34:03] <zhennanf> oh yes you are right, sorry
[10:34:48] <seb_kuzminsky> hi zhennanf
[10:35:07] <seb_kuzminsky> if you find a feature request or bug that has been fixed, but the ticket is still open, let me know and i'll close it
[10:35:33] <cradek> because of the rounding I think this patch may break the default of minimum spindle override = 0, so I suggest testing that case, which will be the usual case
[10:36:58] <zhennanf> Hi Sebastian, lookes like someone have already add the feature-request #60
[10:38:38] <seb_kuzminsky> i'll look at it
[10:38:40] <seb_kuzminsky> thanks
[10:38:41] <seb_kuzminsky> bbl
[10:45:07] <mozmck> cmorley1: looks like I missed you - said it was 12:45 AM here :)
[10:48:49] <mozmck> The problem I'm having, is if I have a button in glade with a related Action, it shows the text of the action even though I set "Use Action Appearance: NO"
[10:49:48] <mozmck> Anyone know why it might be doing that?
[10:52:16] <zhennanf> Sebastian could you have a look at my current version of proposal?
[10:54:11] <zhennanf> I'm still working hard on arranging the schedule, probably I will need to drop one or two tickets like #68
[10:55:31] <zhennanf> I really knows little about machine stuff and don't know wether it will take me too much time to figure out all the tricks needed in this ticket
[11:05:52] <cradek> #68 is very badly described
[11:19:48] <mozmck> when I run fakeroot debian/rules I get this at the end: Makefile:467: warning: undefined variable `COPY_CONFIGS'
[12:07:52] <the_wench> dgarr: jepler said you should take a look at the code here, I think it's a typo: tcl/tooledit.tcl:1104: switch $argct] {
[12:08:12] <cradek> the_wench: he did that days ago
[12:09:03] <dgarr> mozmck: warning: undefined variable -- that is leftover from earlier commit b92baa8, i will amend the Makefile
[12:20:05] <KGB-linuxcnc> 03Dewey Garrett 052.7 8033f40 06linuxcnc 10src/Makefile Makefile: remove ref to unused COPY_CONFIGS * 14http://git.linuxcnc.org/?p=linuxcnc.git;a=commitdiff;h=8033f40
[12:29:59] <skunkworks> cradek, don't be so hard on the_wench
[12:32:31] <cradek> stupid forum
[12:32:55] <cradek> under the user's picture it says "Posts: 4" but that's not a link that lets you see their other posts
[12:33:12] <cradek> you can go to their profile (after you sign in) but it's not there either
[12:33:27] <cradek> in fact there's nothing useful
[12:33:47] <cradek> except "city/state/zipcode" which is embarrassingly US-centric
[12:36:10] <cradek> LinuxCNC.org has 6415 registered users
[12:36:24] <cradek> ... and here's a list of them spread over 214 pages and in no particular order
[12:52:11] <archivist> I hate forums too :)
[13:06:01] <cradek> I just can't believe they're not sorted by ... anything
[13:06:22] <cradek> chaoskreator, awkwardmutton, wood, crazyprofessor, aaron
[13:06:42] <cradek> I guess you just click through the 214 pages and scroll up and down on each one until you find what you want
[13:07:02] * cradek closes a tab and takes a deep breath
[13:07:48] <archivist> probably sorted in join order
[13:08:42] <skunkworks> do you really have to have the classic ladder gui open for modbus to work?
[13:08:55] <jepler> skunkworks: aiui, yes
[13:09:01] <skunkworks> huh
[13:09:10] <jepler> skunkworks: the RT part can't do serial or network modbus communication
[13:09:11] <cradek> the world is full of surprises
[13:11:53] <mozmck> I've seen other forums that do allow you to view all posts by someone - I wonder if this one can be configured to do that?
[13:12:01] <jepler> ideally, it *could* be a third process, but .. somebody would have to do something
[13:16:00] <skunkworks> so the gui has the userspace modbus stuff in it.
[13:16:43] <skunkworks> For some reason I thought there was a generic modbus hal componant now - but I am not findng it.
[13:17:10] <skunkworks> maybe I am just thinking about the hand full of vfd componants.
[13:19:23] <zhennanf> Sebastian, are you available to have a look at my proposal now?
[14:49:48] <seb_kuzminsky> skunkworks: mb2hal
[14:49:56] <seb_kuzminsky> zhennanf: yes, i will look now
[14:54:57] <skunkworks> seb_kuzminsky, I don't see it in the docs
[14:55:13] <seb_kuzminsky> there probably arent any :-/
[14:55:53] <seb_kuzminsky> yeah, there's just the stuff in src/hal/user_comps/mb2hal unfortunately
[14:56:01] <skunkworks> ok - there is a wiki on it
[14:56:19] <skunkworks> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?ModbusToHal
[14:57:51] <seb_kuzminsky> https://sourceforge.net/p/emc/feature-requests/131/ ;-)
[17:38:30] <seb_kuzminsky> zhennanf: did you see my comment on your proposal?
[19:36:04] <cmorley1> skunkworks: there is a pin to hide the classiclader gui while using modbus if you like.
[19:36:25] <skunkworks> cmorley1: oh - cool
[19:37:17] <cmorley1> think it's classiclader.0.hidegui or close to that
[19:37:46] <skunkworks> ok - I was going to try to help this thread http://www.cnczone.com/forums/chinese-machines/264198-nowforever-d100-vfd-control-using-linuxcnc.html
[19:37:55] <skunkworks> Just have not used modbus before
[19:43:18] <skunkworks> Thank you.
[19:44:06] <cmorley1> mozmck: yes i have had a problem with action/button text/image. I forget specifically how I fixed it :( but was some combo of button/action display options. I couldn't repeat the problem just now...do you have a glade file that you could send me with the problem.
[21:40:16] <zhennanf> seb_kuzminsky: yes, I just had a sleep after finishing my proposal, thanks for you comment :)
[23:54:06] <seb_kuzminsky> zero-cost cad/cam from autodesk: http://forums.autodesk.com/t5/design-differently/how-and-why-we-re-building-fusion/ba-p/5496355
[23:56:53] <seb_kuzminsky> but not on linux, of course
