[00:10:48] <elmo40> turning something that is 18tonnes at the moment
[00:11:25] <Tom_itx> what keeps the crank from sagging in the middle when it's being turned?

[11:16:35] <commanderKern> hello everybody
[11:17:16] <commanderKern> i have a problem compiling emc2 i already searched the inet but couldn't find a answer
[11:17:25] <commanderKern> the problm is as follows
[11:17:27] <commanderKern> collect2: ld returned 1 exit status
[11:17:27] <commanderKern> make: *** [../bin/gs2_vfd] Error 1
[11:17:37] <commanderKern> anybody any ideas or hints?
[11:18:40] <jthornton> are you compiling emc because you changed something in the source code?

[11:25:49] <mhaberler> commanderKern: run a 'make V=1' and post the ouput
[11:27:49] <jthornton> mhaberler: what does the V=1 flag return?
[11:28:05] <mhaberler> verbose make output - shows commands
[11:28:23] * jthornton makes a note of that :)
[11:28:47] <mhaberler> I wrote it up on http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?MakefileDeMystified
[11:29:02] <mhaberler> 'Passing flags to the Makefile'
[11:29:13] <jthornton> nice
[11:29:36] <mhaberler> been there, sat in that trap ;-)
[11:31:00] <jthornton> glad to know where that is now
[11:35:13] -!- vladimirek has quit [Remote host closed the connection]
[11:36:53] <fragalot> hm. The search for a desktop lathe continues
[11:38:50] <commanderKern> <mhaberler> yes i will do that
[11:38:57] <commanderKern> but where shall i post it?
[11:39:04] <commanderKern> probably not in the irc
[11:39:22] <mhaberler> pastebin.com
[11:39:30] <jthornton> so the last one you found didn't pan out?
[11:39:31] <mhaberler> and paste link here
[11:39:59] <commanderKern> do i need an account there?
[11:40:13] <jthornton> no
[11:40:17] <commanderKern> good
[11:40:33] <jthornton> did you modify emc then try and compile?
[11:41:38] <commanderKern> no i just downloaded the latest version from git
[11:41:54] <jthornton> 2.5?
[11:41:59] <mhaberler> do you have the build dependencies installed?
[11:42:29] <commanderKern> i don't know the version just the master branch
[11:42:46] <commanderKern> yes dependencies are installed and i am running ubuntu 11.10
[11:42:59] <jthornton> oh, good luck
[11:42:59] <mhaberler> 11.10, sosos
[11:43:14] <mhaberler> post output of 'uname -a'
[11:43:37] <commanderKern> Linux laptop 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:50:42 UTC 2011 i686 i686 i386 GNU/Linux
[11:45:10] <mhaberler> go install from the livecd and forget about 11
[11:45:10] <mhaberler> wrong kernel - no realtime
[11:45:10] <commanderKern> i didn't want to run it realtime
[11:45:11] <mhaberler> follow instructions as per http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2
[11:45:11] <commanderKern> i used the sim flag
[11:45:11] <jthornton> do you just want a simulator?
[11:45:11] -!- mendelbuild has quit [Ping timeout: 256 seconds]
[11:45:11] <commanderKern> for the beginning i thougt it wuold be the easiest way
[11:45:30] <mhaberler> is there any hard reason not to use the liveCD to start with?
[11:45:32] <commanderKern> but as it turns out
[11:45:49] <commanderKern> maybe patching the kernel wuold have been done by now
[11:46:30] <commanderKern> is there any reason why this software is so version dependent?
[11:47:13] <mhaberler> I do not know 'your version', we need to start from a common baseline or its all stabs in the dark
[11:47:27] <mhaberler> the Makefile output would help, too
[11:47:35] <commanderKern> yes i am on it
[11:47:37] <commanderKern> sorry
[11:48:30] <jthornton> read the top of this page about versions http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?EmcKnowledgeBase
[11:51:57] <jthornton> commanderKern: have you seen this page? http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?EMC2_Pure_Simulator
[11:52:44] <mhaberler> "EMC2 is not supporting 11.04"
[11:53:17] <commanderKern> i have 11.10;-)
[11:53:46] <commanderKern> shall i still post the uotput or is it obolete?
[11:53:52] <mhaberler> YESS
[11:55:24] <commanderKern> http://pastebin.com/9zfJsjCM
[11:56:17] <commanderKern> seems to be some problem with the linking of gs2_vfd
[11:56:29] <mhaberler> great, now where's the error message?
[11:56:59] <mhaberler> this paste shows no error
[11:57:21] <commanderKern> wait a moment
[12:00:38] <commanderKern> http://pastebin.com/DUfsgccf
[12:00:42] <commanderKern> so there is the error
[12:01:20] <commanderKern> i tried to pipe it into a file but this didn't work obviously so this is only the far i could scroll back
[12:04:32] <mhaberler> modbus.c is referencing a glib function g_print() which isnt in your glib
[12:05:11] <commanderKern> that is bad
[12:05:37] <JT-Shop> for a simulator just install a VM of 10.04
[12:05:42] <commanderKern> how do i get this function
[12:05:45] <mhaberler> can I ask again: is there any hard reason not to use the liveCD to start with?
[12:05:59] <commanderKern> no i don't think there isn't
[12:06:02] <commanderKern> thanks alot
[12:06:14] <JT-Shop> it is a laptop...
[12:06:18] <commanderKern> yes
[12:06:22] <mhaberler> look, there is a reason why it says "EMC2 is not supporting 11.04", and you might have just hit one of them
[12:06:30] <commanderKern> yes
[12:06:35] <commanderKern> i am not complaining
[12:06:48] <commanderKern> i just thougt maybye if i compile but...
[12:06:50] <mhaberler> ok, cu - gotta run
[12:06:52] -!- mhaberler has quit [Quit: mhaberler]
[12:07:42] <commanderKern> i think i will go looking for g_print()
[12:09:28] <commanderKern> not to piss anyone of the developers off but did you know
[12:09:31] <commanderKern> g_print() should not be used from within libraries for debugging messages, since it may be redirected by applications to special purpose message windows or even files. Instead, libraries should use g_log(), or the convenience functions g_message(), g_warning() and g_error()
[12:09:50] <commanderKern> seen on http://developer.gnome.org/glib/2.30/glib-Warnings-and-Assertions.html
[12:13:04] <commanderKern> anyone here who knows how often this function is used in emc2 or is it only used in modbus.c
[12:13:24] <commanderKern> so i could replace it with g_log()
[12:20:03] <JT-Shop> grep for it and you will see
[12:24:48] <commanderKern> i was trying to do that
[12:24:56] <commanderKern> no not in the source code
[12:25:28] <commanderKern> i tried to grep for g_print in /usr/include/glib-2.0
[12:25:34] <commanderKern> but did not get anything
[12:25:59] -!- isssy [isssy!~isssy@78-83-51-185.spectrumnet.bg] has joined #emc
[12:25:59] <commanderKern> so i really do not have this function or am i grepping in the wrong place
[12:26:19] <JT-Shop> from the emc2-dev directory try grep -i -r 'g_print()' *
[12:26:47] <JT-Shop> arggg I'm turning into a geek I know grep by heart :/
[12:27:04] <commanderKern> no problem
[12:29:36] <commanderKern> i for ignore and r for recursive is not that hard to remember ;-)
[12:39:18] -!- JT-Shop has quit [Remote host closed the connection]
[12:42:32] <commanderKern> okay i am sure i have the g_print function i my system under /usr/include/glib-2.0/glib it is in and gunicode.h and gmessages.h
[12:43:23] <commanderKern> these two libs are included in glib.h which is included in modbus.c

[12:45:54] <JT-Shop> now if I can just finger out why I can connect to the D525 from this winblows computer... no doubt something wrong with shares
[12:51:06] <JT-Shop> oh bother no samba installed on the darn thing
[12:55:30] <commanderKern> anyone here who has a opinion on g_print ?
[12:59:57] <JT-Shop> well that ain't the problem :/
[13:01:28] <commanderKern> ~
[13:01:52] <commanderKern> okay so i found out modbus.c is the only file using the g_print
[13:02:06] <commanderKern> no onje else does this i wil try to replace this now
[13:02:32] <commanderKern> i do not have big experience with that but i think this unction just sucks

[13:48:27] <Tom_itx> JT-Shop you figure that out?
[13:48:45] <Tom_itx> i think i had a similar problem and just went the other direction
[13:48:58] <JT-Shop> no, it is a puzzle as my CHCN is running 10.04 and I have no problems sharing with it
[13:48:59] <Tom_itx> shared the win folder so i could use it
[13:49:00] <commanderKern> i wonder that noone is interested in this bug
[13:49:16] <JT-Shop> I hate bugs
[13:49:21] <Tom_itx> JT-Shop, is your CHCN a 5.10?
[13:49:27] <Tom_itx> err 510 atom
[13:49:36] <Tom_itx> ?
[13:49:43] <commanderKern> there is obviously a big problem with the glib2.0 and their functions
[13:49:45] <JT-Shop> no it is a zotac with an atom
[13:49:57] <commanderKern> maybe some compiler flags or
[13:50:02] <Tom_itx> i had similar problems with my D525
[13:50:10] <Tom_itx> not that the board is the issue
[13:50:20] <Tom_itx> more likely me
[13:50:37] <commanderKern> or the modbus.c is poorly programmed
[13:51:01] <JT-Shop> you just need to fix it then
[13:56:05] <JT-Shop> it has to be some configuration on the D525...
[13:56:12] <commanderKern> good answer
[13:56:41] <commanderKern> yes i wuld like to try but the support here is a bit don't know how to say this polite
[13:56:49] <Tom_itx> JT-Shop, for now i just shared the windows folder until i can figure it out
[13:57:29] <JT-Shop> yea, I'm just going to reinstall 10.04 on it
[13:58:05] <Tom_itx> i considered that once i get everything set
[13:58:35] <JT-Shop> commanderKern: while there may be many users logged in here it doesn't mean anyone is sitting in front of there computer to instantly answer your questions
[13:58:47] <commanderKern> yes i know that
[13:58:48] <JT-Shop> there seems to be some reason we have a mailing list

[13:59:06] <Tom_itx> :)
[13:59:21] <JT-Shop> I hate the mailing list but try and follow it as well
[14:00:01] <Tom_itx> started my new probe last night
[14:00:05] <Tom_itx> smaller
[14:00:17] <JT-Shop> and this is an open source project that is not funded with 24/7 tech support.... </ranting off>
[14:00:20] <JT-Shop> nice
[14:00:32] <commanderKern> o don't want tech support
[14:00:40] <commanderKern> i am just trying to fix a bug
[14:00:56] <commanderKern> i cannot believe that ist run son 10.04 but not on 10.11
[14:01:11] <commanderKern> nad it is just this one stupid thing with the g_ functions
[14:01:18] <commanderKern> thats driving me crazy
[14:06:43] <JT-Shop> it's not a bug if it runs on supported versions
[14:06:52] <commanderKern> it is a feature ;-)
[14:13:15] <JT-Shop> the neat thing about open source code is if it doesn't work for you you can change it...

[19:03:49] <skunkKandT> neat
[19:04:03] <skunkKandT> I like those mills. They seem to be built well

[19:07:15] <Dallas-Maker-Spa> I agree, well designed
[19:07:39] <skunkKandT> I can see where the ladder could be tweeked. There should be a few tenths of a second delay before the arm pulls out to let the spindle collet unclamp

[21:04:06] <andypugh> Plugs into a 5i25 (which is a low-profile FPGA board, with 2x 25 pin connectors, rather than 50 way headers)

[21:30:00] <andypugh> So, sserial_mode0=20000000 should give you a few extra ananlogue inputs
[21:33:40] <andypugh> The fly in the ointment is that with my card at least, you get the extra pins, but the whole card stops working. (have a look at the hm2_5i25.0.7i76.0.0.status parameter, if that isn't 0x00420000 then you have the same problem as me.
[21:35:44] <JT-5i25> hmm, I don't have any 7i76 pins at all
[21:35:46] -!- FinboySlick [FinboySlick!~shark@74.117.40.9] has joined #emc
[21:36:05] <JT-5i25> is that because the 7i76 card is not powered up
[21:40:45] <JT-5i25> jumpers seem to be correctl
[21:40:48] <JT-5i25> correct
[21:43:58] <andypugh> The card needs 12V into the header, aye
[21:44:50] <JT-5i25> ok, I need to find a 12v power supply... a wall wort should work?
[21:45:12] <andypugh> Wall wort? Too much hime-brewing?
[21:45:21] <pcw> There are 2 power supplies on the 7I76:
[21:45:23] <pcw> 1. 5V from the 5I25 (this need the 5V power option jumpers set right on both the 7I76 and 5I25)
[21:45:25] <pcw> if this is OK you should have the leftmost Yellow LED on
[21:45:26] <pcw> 2. You need field power for the isolated SSERIAL I/O (12 -28V) otherwise you will not get the 48 SSERIAL I/O
[21:45:39] <andypugh> (home brewing). Note to self, check spelling when criticising spelling.
[21:45:50] <pcw> if this is on you will get the rightmost Yellow LED on
[21:46:38] <JT-5i25> ok I have 24v power supply I'll check the jumpers
[21:50:47] <pcw> better check with Andy about the 24V polarity I think the current manual is correct there
[21:50:49] <pcw> but after getting all power supply polarities wrong I wouldn't trust it much
[21:52:57] <JT-5i25> yea the 5i25 W1 is down

[22:16:21] <andypugh> W2 to the left

[22:17:14] <JT-5i25> W1 is up on the 5i25
[22:18:26] <andypugh> Odd. Official Mesa Parallel cable?
[22:18:47] <JT-5i25> yep
[22:19:01] <andypugh> Pete!
[22:19:26] <pcw> try setting W2 up
[22:19:36] <pcw> 5I25 W2
[22:19:39] <JT-5i25> ok

[22:22:18] <JT-5i25> and we have 7i76 in the pins list
[22:22:48] <Tom_itx> woot!
[22:22:55] <Tom_itx> never doubted you
[22:23:30] <JT-5i25> so the 5i20 W1 is for P2 and the W2 is for P3?
[22:23:39] <pcw> batting 0/3 in the manual
[22:23:44] <JT-5i25> LOL
[22:23:52] <JT-5i25> that is what testing is for :)
[22:23:55] <pcw> yes
[22:24:50] <JT-5i25> I think spinning a stepper will be next...
[22:25:09] <JT-5i25> oh I forgot to check 2000000000
[22:26:39] <JT-5i25> andypugh: you have CONFIG="sserial_mode0=11000000" and CONFIG="sserial_mode0=20000000" what was the third choice?
[22:26:55] <Tom_itx> well maybe by the time i get around to one it'll all be perfect
[22:26:55] <andypugh> 0000000
[22:28:00] <andypugh> Only the first digit matters, the second controls a second board plugged into the 7i76. I imagene that the third digit would be the second 7i76, and the 4th the board plugged into that.
[22:28:22] <JT-5i25> 0x001EA188 hm2_5i25.0.7i76.0.0.status
[22:28:31] <andypugh> Mode 1?
[22:28:35] <JT-5i25> 2
[22:28:45] <andypugh> Yes, I get that too.
[22:28:54] <andypugh> It's not a good sign.
[22:29:03] <andypugh> Mode 0 should work.
[22:29:16] <andypugh> (you probably need to power-cycle the 7i76)
[22:30:09] <andypugh> I am wondering what part of "vacation" PCW is misunderstanding
[22:30:32] <JT-5i25> you might be correct as changing modes then running the config results in no 7i76 pins
[22:31:07] <JT-5i25> power cycle both cable power and field power?
[22:31:41] <andypugh> Just field power, I think
[22:32:02] <JT-5i25> ok
[22:32:27] <andypugh> I was hoping I had a rogue firmware, but it looks like the bug fix firmware introduced more serious ones.
[22:33:05] <JT-5i25> 0x00420000 hm2_5i25.0.7i76.0.0.status mode 0
[22:33:35] <andypugh> It might be the driver, too. That is actually quite likely, as I wrote the driver (rank amateur) and PCW wrote the firmware (pro)
[22:34:02] <andypugh> 42 is the answer to life, the universe, and everything, and is what you should see.
[22:34:03] <JT-5i25> is the mode 0 status ok
[22:34:22] <andypugh> Yes, ox00420000 is good.
[22:34:32] <JT-5i25> I'll try 1 again

[22:35:50] <JT-5i25> good or bad
[22:37:02] <andypugh> Bad
[22:37:26] <JT-5i25> ok
[22:37:34] <andypugh> It seems that only mode 0 works. But that's probably all you need
[22:38:07] <andypugh> You lose field-voltage monitoring, and 4 8-bit analogue inputs.
[22:38:39] <JT-5i25> so something in the driver is borked the stuff you were working on the other day?
[22:39:15] <andypugh> No, it was all working, then I updated the card firmware...
[22:41:42] <JT-5i25> ah so me and you have the same firmware atm
[22:44:47] <JT-5i25> I have a test stepper with an encoder attached that could be used to simulate a velocity controlled spindle with encoder feedback :)
[22:49:08] <pcw> Yeah looks like a 7I76 firmware error
[22:49:10] <pcw> error code 91is toomanyerrors+toomanychars+crcerror
[22:49:12] <pcw> which likely means the 7I76 firmware neglected to tell the SSLBP firmware in the 5I25
[22:49:14] <pcw> the correct number of characters to expect
[22:49:47] <pcw> (for the modes other than 0)
[22:50:46] <JT-5i25> I'll work in mode 0 for now then

[23:02:00] <pcw> yep
[23:02:14] <JT-5i25> thanks
[23:02:33] <pcw> that part is no different than any other mesa config
[23:03:39] <JT-5i25> just doing a chicken check
[23:04:29] <pcw> though the 7I76 does have buffered 5V STEP/DIR signals so should work with most STEP/DIR inputs with no fuss
[23:05:19] <pcw> for drives that will accept differential inputs you can connect across the +- outputs

[23:29:02] <JT-5i25> opps TB3 on the 7i76 has two IDX- pins... I assume the first one is really IDX+
[23:30:50] <andypugh> I think PCW should double our pay for all this testing
[23:31:04] <JT-5i25> aye
[23:31:25] <JT-5i25> do you connect the shield wires to the 7i76 gnd?
[23:32:41] <owhite> hello people. I was wondering if a independent program could pass a signal to EMC. The purpose would be for the program to be running on my linux box, and it could pass a signal to EMC to throw an e-stop.
[23:34:50] <Eartaker> why would you want to do that?
[23:35:20] <ve7it> pcw, do you know of anyone that has built a daughter board that plugs onto a 5i20 that contains 3 or so 24bit stereo A/D chips? I am looking to build a side scan sonar
[23:36:24] <pcw> ve7it: No not offhand
[23:36:39] <andypugh> ve7it: Isssy is the closest, he is making clone Hostmot2 boards
[23:36:42] <owhite> ertaker: I have a CNC laser. I have a problem with my optics which are very close to the sheet metal that gets cut, bumping into parts that pop out after they're cut. I'm going to have an external program monitor if something runs into the my optics, and i want it to throw and e-stop.
[23:36:54] <JT-5i25> pcw: did you see the IDX- typo in the 7i76 manual?
[23:37:00] <owhite> s/and/an/
[23:37:12] <ve7it> pcw, I would like to do a correlation with the TX signal in the FPGA
[23:37:13] <andypugh> owhite: Why not monitor in EMC2?
[23:37:19] <JT-5i25> yea
[23:37:33] <pcw> JT-5i25: probably if the encoder shield is open at the encoder end
[23:37:35] <owhite> andypugh- the detection system will be based on a webcam.
[23:38:07] <owhite> To my knowledge I cant interface the webcam and software that operates on the webcam data directly to EMC.
[23:38:16] <pcw> JT-5i25 thanks Ill make a note of it
[23:38:23] <JT-5i25> np Peter
[23:38:40] <andypugh> owhite: Still potentially do-able. EMC2 has a webcam interface. But simpler is probably emcrsh. (or possibly emcsh if running on the same PC)
[23:38:54] <JT-5i25> the two encoders that show up for the 5i25 are one each on daughter cards?
[23:39:59] <andypugh> owhite: Can you call a bash script? halcmd sets estop-ext is probably all you need, assuming that you have a signal called estop-ext in the HAL file.

[23:41:07] <pcw> Yes theres just one encoder interface on the 7I76
[23:41:09] <JT-5i25> owhite: on some automatics we used lasers to make sure nothing has "popped up" and connect it directly to an input
[23:41:20] <JT-5i25> ok, I assumed such
[23:41:43] <pcw> for TTL encoders you could just wire to the second connector
[23:42:25] <JT-5i25> so if for some strange reason you had two 7i76 cards one is encoder.0 and one is encoder.1?
[23:42:28] <owhite> andypugh: what would make the call the bash script?
[23:42:52] <pcw> Yes
[23:43:02] <JT-5i25> ok, that makes sense
[23:43:05] <andypugh> owhite: I don't know, I am not very good with Linux
[23:43:59] <pcw> but you could also have a config with more encoders on the other header
[23:44:18] <JT-5i25> ok
[23:48:22] <pcw> If the extra encoder is for a MPG the 7I73 will eventually be a good solution (and it can connect to the 7I76)
[23:48:52] <JT-5i25> on the RS-422 lines?
[23:49:22] <pcw> Yes
[23:49:39] <andypugh> pcw: Does anyone have a 7i73 yet? I _think_ the counter interface works.
[23:51:37] <pcw> Only us so far still not quite done:
[23:51:39] <pcw> Keypad works
[23:51:41] <pcw> Encoders work (up to 50 KHz)
[23:51:43] <pcw> analog in works
[23:51:44] <pcw> LCD works but needs FIFO/statemachine work
