[00:26:11] <seb_kuzminsky> mshaver, when you're working on a commit, you should try to make the commit on the oldest branch that wants it, and then not commit it on any newer branches
[00:26:39] <seb_kuzminsky> the commit will be propagated to the newer branches when the older branches are merged, which should happen often
[00:26:59] <seb_kuzminsky> you can do the merge yourself if you feel confident you can get it right, or can back it out if it goes haywire
[00:27:26] <seb_kuzminsky> or just ask one of the branch release managers (chris or jeff), or me
[00:34:40] <andypugh> What does it mean when any command (such as dmesg) just returns "Killed"?
[00:34:49] <andypugh> Nothing good, I imagine
[00:37:05] * seb_kuzminsky points at andypugh's power switch
[00:37:14] <mshaver> I may not understand merges. Suppose a change is made in 2.4 that shouldn't be propagated to 2.5?
[00:37:36] <seb_kuzminsky> i think that should almost never happen
[00:37:55] <seb_kuzminsky> but if it does, it helps the person doing the merge if the commit message says so, and says why
[00:38:53] <seb_kuzminsky> at which point they can do a normal merge of everything up to but not including the special commit, then use the "ours" merge strategy for that one commit, then merge the rest of the old branch with the normal merge strategy
[00:39:11] <SWPadnos> one case where that might happen is a bugfix in a module that has been discontinued/replaced in the later version
[00:39:19] <seb_kuzminsky> it's a bit of a hassle and a bit susceptible to human error, but it does work pretty well
[00:39:26] <mshaver> so the merge process is controlled by the merger (human). it's not just, "make all adds and edits from 2.4 on 2.5"?
[00:40:10] <seb_kuzminsky> mshaver, ideally it is: the less the human has to do, the better
[00:40:27] <mshaver> as you can tell, i really have no idea :)
[00:40:33] <seb_kuzminsky> git does all the easy things for you automatically, and punts all the ambiguous bits up to the human
[00:40:52] <seb_kuzminsky> as a developer you don't have to worry about merges if you don't want to
[00:41:12] <andypugh> would it be safer, in that case, to have a commit in the upstream branch that reverts the first commit?
[00:41:26] <seb_kuzminsky> it's enough to make good commits (with clear descriptive commit messages) where they belong (in the oldest applicable branch)
[00:41:37] <seb_kuzminsky> andypugh, i think that would be more confusing
[00:41:45] <mshaver> ok, i will try to work with this in mind!
[00:42:07] <seb_kuzminsky> thanks!
[00:42:23] <seb_kuzminsky> your commits are generally quite good and very much appreciated
[00:43:14] <andypugh> I noticed a stupid bug in led.c
[00:44:03] <andypugh> I was looking at ways to correctly identify the cards to specify the number of led pins.
[00:44:28] <seb_kuzminsky> the llio driver should tell the hostmot2 how many leds there are
[00:44:44] <seb_kuzminsky> just like it already says how many connectors, and what the board name is, etc
[00:44:59] <andypugh> Aye, but how does it know?
[00:45:39] <seb_kuzminsky> andypugh, the llio author reads the board manual and puts it in the board probe code
[00:46:03] <andypugh> Anyway, the bug is a real noob mistake, checking strcmp for "TRUE"
[00:46:26] <seb_kuzminsky> mshaver, here's a problem: you added 1034gecko.ini in both 2.4 and master
[00:46:28] <andypugh> Yeah, that is a better solution. I will look into it.
[00:49:27] <seb_kuzminsky> mshaver, the two files are different
[00:50:47] <seb_kuzminsky> looks like the one in 2.4 got additional commits that tweaked the file
[00:50:49] <mshaver> I was just looking for that file in the 2.5 branch
[00:51:05] <seb_kuzminsky> i hope i did the merge right! if i messed it up let's fix it
[00:52:08] -!- stormlight has quit [Quit: stormlight]
[00:52:34] <mshaver> if i want that file in 2.5, do i add it? or does merging add the files to the newer branches
[00:53:50] <mshaver> first i've got to finish the changes i've started...
[00:54:47] <seb_kuzminsky> the right way to do your recent commits would have been to do the work in the 2.4 branch only, and then merge up to the newer branches (or ask me to do the merge)
[00:55:55] <seb_kuzminsky> i think what you want is this: new 1034 ini file in all branches, with one version in the 2.4 branch and a slightly different version in the 2.5 and master branches (2.5 and master should have the same version)
[00:55:57] <seb_kuzminsky> is that right?
[00:57:00] <mshaver> yes
[00:57:36] <seb_kuzminsky> ok
[00:57:59] <mshaver> actually, all the .ini files are different between 2.4 & 2.5
[00:58:11] <seb_kuzminsky> i think you mean for the two versions of the 1034 ini file to differ in two ways:
[00:58:31] <seb_kuzminsky> 1: 2.5 & master have TKPKG lines, 2.4 does not
[00:58:46] <mshaver> to accommodate the different ini file syntax of ngcgui
[00:58:53] <seb_kuzminsky> 2: 2.5 & master have SUBROUTINE_PATH and USER_M_PATH lines, but 2.4 does not
[00:59:01] <mshaver> yes & yes
[00:59:11] <seb_kuzminsky> ok cool, then i'm on the right track with the merge :-)
[00:59:28] <mshaver> 3. 2.4 has TKAPP lines
[00:59:54] -!- Eartaker has quit [Ping timeout: 255 seconds]
[00:59:55] <seb_kuzminsky> 2.4 and 2.5 and master all have TKAPP lines currently
[01:00:03] <seb_kuzminsky> is that not right?
[01:00:12] <mshaver> I tried to come up with files that would work with either version
[01:00:42] <mshaver> no, I think TKAPP changes to TKPKG from 2.4 to 2.5
[01:01:02] <seb_kuzminsky> ah ok, that's not what's currently in the files tho
[01:01:04] <seb_kuzminsky> easy to fix
[01:01:32] <seb_kuzminsky> so the way to do this cleanly would have been to add 1034.ini to 2.4
[01:01:36] <seb_kuzminsky> then merge 2.4 into 2.5
[01:01:40] <mshaver> Also, 'USER_COMMAND_FILE = tkapp.py' goes away in 2.5
[01:01:48] <seb_kuzminsky> then do a new commit in 2.5 to fix the syntax
[01:01:52] <seb_kuzminsky> then merge 2.5 into master
[01:02:09] <mshaver> yes
[01:02:29] <seb_kuzminsky> no biggie, i'm cleaning it up now
[01:02:45] <mshaver> 'cleanly', maybe that's the concept i'm missing?
[01:03:03] <seb_kuzminsky> heh

[05:38:35] <AitalMAC> Is it possible to write a subroutine to override limits?
[05:40:43] -!- mhaberler has quit [Quit: mhaberler]
[05:45:38] <AitalMAC> Is it possible to write a subroutine to override limits?
[05:46:36] <awallin_> I would guess it is easier to start with very large limits and then in software reduce those limits
[05:46:54] <AitalMAC> i cannot set my parport as IN i have try them all but i only can read some input (pin 10)
[05:47:33] <awallin_> I don't see how that relates to the numerical values of hard/soft limits
[05:48:20] <AitalMAC> it's because i have 2 different problems that i'm trying to fix sorry
[05:49:09] <AitalMAC> where the hard soft limits values are stored?
[05:50:13] -!- seb_kuzminsky has quit [Ping timeout: 240 seconds]
[05:50:18] <AitalMAC> how can i reduce the soft limits?
[05:50:49] <awallin_> INI file has min_limit and max_limit for each [axis] section
[05:51:04] <AitalMAC> Yes i see
[05:51:19] <AitalMAC> Can i change them with a subroutine?
[05:52:51] <awallin_> I don't know, motion has debugging pins axis.N.neg-hard-limit and axis.N.pos-hard-limit
[05:53:12] <awallin_> I don't know if "soft limit" and "hard limit" are used consistently in the docs
[05:53:53] <awallin_> I think with an M-code or something you could write to a HAL-pin/variable. you could then write your own HAL to compare this value to the axis-position and trigger a limit switch if you are over the limit.
[05:54:10] <AitalMAC> when i home with a limit switch on Axis an override limit check apperas
[05:54:18] <AitalMAC> how does that work?
[05:54:50] <AitalMAC> appear
[05:56:33] <AitalMAC> ok i get it making a limit inside the limit with hal, and change the limit when i need to
[05:57:12] <awallin_> I don't think overriding limits is possible from HAL or from g-code. The ui (AXIS) probably does that through NML (?)
[06:00:02] <AitalMAC> but if i use what you are suggesting the limits will not be counted when i load a wrong G-code that is out of limit

[08:20:06] <AitalMAC> I am not able to use my parport in IN direction
[08:20:23] <AitalMAC> I set the parport IN inside the HAL file
[08:20:51] <AitalMAC> Axis opens up i can see all the in pins, but only some function
[08:21:01] <AitalMAC> most of them do not work
[08:21:53] <AitalMAC> I tryed changing the BIOS settings of the parport to SPP but it's no use
[08:22:29] <archivist> are you expecting any pin to be input? as only certain pins can be used for input in some modes
[08:27:12] <AitalMAC> What you mean?
[08:27:26] <AitalMAC> The IN mode has a lot of inputs
[08:27:49] <AitalMAC> but i can only read some with my parport
[08:28:22] <AitalMAC> i have a PCI card with two Parport, only one of these can work fine when i set it to IN

[08:30:16] -!- pjm has quit [Quit: TTFO]
[08:30:28] <archivist> are you letting stepconf set it up for you
[08:30:28] <AitalMAC> i'm expectin it to work like in this picture http://linuxcnc.org/docs/html/parport-block-diag.png
[08:30:37] <AitalMAC> no i do it manually
[08:30:39] -!- pjm [pjm!~pjm@uhfsatcom.plus.com] has joined #emc
[08:31:24] <AitalMAC> stepconf i think has a bug when i set as in it writes out in the hal file
[08:31:29] <AitalMAC> so i do it manually
[08:31:42] <AitalMAC> loadrt hal_parport cfg="0x378 0xa800 in"
[08:31:50] <AitalMAC> and then
[08:31:51] <AitalMAC> addf parport.1.read base-thread
[08:31:51] <AitalMAC> addf parport.1.write base-thread
[08:33:10] <AitalMAC> I just change the "0x378 0xa800 in"
[08:33:27] <AitalMAC> i put "0x378 in"
[08:33:33] <AitalMAC> and it does not work
[08:33:52] <AitalMAC> my other 2 ports address are 1030 and 1020 and they work fine if set as out
[08:33:59] <archivist> try step conf and look how that sets up hal for you
[08:34:10] <AitalMAC> ok
[08:35:04] <archivist> dont forget to save current configuration stepconf trashes what you have unless you create a new configuration
[08:51:37] <AitalMAC> where are trashes?
[08:52:02] <AitalMAC> i never deleted any trash and everything else has been working
[08:52:45] <AitalMAC> Oh don't forget that saving current conf
[08:52:50] <AitalMAC> it's ok i know
[08:53:08] <AitalMAC> i have set with stepconf and it does not work
[08:53:16] <AitalMAC> stepconf as i sayd before has a bug
[08:53:58] <AitalMAC> you set in and it writes out, and then nothing works, if i set the second port as out it will write in inside the HAL, but the port will still not be working
[08:54:04] <AitalMAC> only pin 10
[08:54:22] -!- adb [adb!~Moldovean@78.96.214.213] has joined #emc
[08:54:35] <AitalMAC> from pin10 to pin 15
[08:54:43] <AitalMAC> the inputs are working
[08:55:08] <AitalMAC> But from 2 to 9 i read nothing
[08:55:30] <AitalMAC> looks as if the port is still in OUT direction
[08:55:45] <AitalMAC> and i read only those input that i can read in OUT direction
[08:56:00] <AitalMAC> All the other that should have switched to IN do not work
[08:56:58] <AitalMAC> I've been after this problem for a few days now, i'm almost sure that i'm not soing anything wrong and that it should work
[08:57:07] <AitalMAC> *doing
[08:57:53] <AitalMAC> I've got to go now, if you find a solution please post on the forum http://www.linuxcnc.org/component/option,com_kunena/Itemid,20/func,view/catid,18/id,13673/lang,english/

[17:47:27] <IchGuckLive> hi Rogge
[17:47:36] <Rogge> Hello!
[17:47:42] <IchGuckLive> did you manage your inch center problem ?
[17:47:44] <Rogge> New CAM and the aprt is running fine....
[17:47:51] <Rogge> Thanks for the help yesterday!
[17:48:00] <IchGuckLive> fine
[17:48:22] <IchGuckLive> what came are you now on
[17:48:32] <IchGuckLive> CAM
[17:48:34] <Rogge> Sprut
[17:49:35] <IchGuckLive> http://www.sprutcam.de this is a germany nanafacture
[17:49:55] <Rogge> Question about touch off: On this long program (20,000 lines) EMC seems to take two minutes to think about the tool path after I touch off an axis.
[17:50:19] <Rogge> Is there any way to stop EMC from thinking about the tool path until all three axes have been touched off?
[17:50:50] <IchGuckLive> dont load the programm first
[17:51:22] <IchGuckLive> emc normaly starts with the text milling file
[17:51:30] <IchGuckLive> did you change this
[17:51:54] <cradek> Rogge: I like IchGuckLive's answer better, but also, you could use G10 L20 P1 X... Y... Z... in MDI, then hit reload once
[17:52:05] <IchGuckLive> and at load of your g-code it is calculatad against the tool .tbl
[17:53:05] -!- GoSebGo has quit [Quit: Bye]
[17:53:31] <IchGuckLive> Rogge: is this a CRC programm or simple path
[17:53:33] <Rogge> Just looking up the doc on G10 L10
[17:53:44] <cradek> http://www.linuxcnc.org/docs/devel/html/gcode/main.html#sec:G10-L20

[17:53:58] <cradek> you need a suitable recent version of emc
[17:54:04] <cradek> suitably
[17:54:06] <Rogge> 2.4
[17:54:43] <Rogge> What is EMC doing in that two minute think time? Drawing a tool path on the display?
[17:54:58] <cradek> yes exactly
[17:55:06] <cradek> processing all the gcode to figure out the path, and drawing it
[17:55:15] <Rogge> If I disabled the backplot would it load more quickly?
[17:55:35] <cradek> I don't think so; the only way is to load a small (or empty) program.
[17:55:43] <Rogge> It's funny, because it is only displaying a sphere with som lines through it - no relation to the actual tool path...
[17:56:17] <cradek> I wish AXIS didn't generate the preview if it's turned off.
[17:57:12] <IchGuckLive> Rogge: is th PC at the requierments
[17:57:30] <Rogge> Yes - the PC is fine...
[17:58:26] <IchGuckLive> did you turn circelinterpolation on at the cam so it shortes the g-code
[17:58:26] <skunkworks> I though in the gcode program you could set a comment that makes axis not preview..
[17:58:51] <cradek> ahh, I forgot about that
[17:58:56] <cradek> skunkworks gets the cookie today
[17:59:01] <Rogge> IchGuck: I found the solid model, re did the CAM at 4 decimal places of precision.
[17:59:30] <cradek> you use a comment like (AXIS,ow ow stopit stopit)
[17:59:37] <Rogge> cradek: so that line in the code to turn off display will make the code reload more quickly on touch off?
[17:59:37] <cradek> ... may not be spelled exactly right
[17:59:58] <cradek> oh yeah, you can tell AXIS to just stop generating preview when it sees that line
[18:00:22] <cradek> http://www.linuxcnc.org/docs/devel/html/gui/axis.html#_special_comments
[18:00:44] <Rogge> Ahah! (AXIS, hide)
[18:01:04] <Rogge> or (AXIS, stop)
[18:01:08] <Rogge> I'll try it!
[18:01:14] -!- giz has quit [Quit: Page closed]
[18:01:35] <Rogge> Any idea where that sphere is coming from on the tool path?
[18:01:45] <Rogge> It's not showing the actual tool path anyway.
[18:01:52] <skunkworks> I have been eating too many cookies lately..
[18:03:00] <IchGuckLive> Rogge: screenshot posibal ?
[18:03:21] <Rogge> You bet - give me a moment...
[18:03:35] <Rogge> Linux newbie question... how to take a screenshot?
[18:05:32] <IchGuckLive> press print
[18:05:39] <IchGuckLive> on the keyboard
[18:05:59] <IchGuckLive> right to F12
[18:07:09] <Rogge> took a photo with the part and the screen - couldn't find a good image pastebin, but this link should work: http://inky.ws/g/m7&msg=Uploaded%20successfully.
[18:08:18] <IchGuckLive> does the part represent the g-code
[18:09:34] <Rogge> That part is cut from the code that Axis displays as a sphere with lines drawn through it.
[18:10:09] <IchGuckLive> the g-code is full loadet 20.000 lines ?
[18:11:42] <Rogge> I must have miscounted yesterday... the full code is 438,871 lines

[18:13:13] <IchGuckLive> so the cut is okay but no display
[18:17:24] <IchGuckLive> did you turn off the priview ?
[18:17:26] <skunkworks> Rogge: that is the datum point in emc (I think the home postion...) your drawing is elsewerhe.
[18:17:37] <skunkworks> else where
[18:18:07] <Rogge> ahh.... sorry for the dumb question then! I'll zoom out, and my part must be around there somewhere...

[20:59:52] <JT-Shop> stepper stalling?
[21:00:58] <Chris_Bri> By stepper stalling do you mean *trying to go forward when at the end of the table*
[21:01:21] <Danimal_garage> lol
[21:01:30] <Danimal_garage> one way to do it
[21:01:31] <JT-Shop> I mean during a rapid move
[21:02:59] <Chris_Bri> I have limited the movement to 1 in/s during setup. I am focused on figuring out how to home the XYZ and getting the correct table Travel settings.
[21:04:03] <JT-Shop> if it homes the wrong way just change the sign of the seek speed

[21:05:12] <Chris_Bri> The Homing sequence requires Switch trips correct?
[21:05:19] <JT-Shop> yep
[21:05:28] <JT-Shop> or it can share the limit switch
[21:05:35] <Chris_Bri> Because the machine purchased does not have any, to my knowledge.
[21:06:03] * Chris_Bri is a completly newbie and just learned that the company bought one today when it arrived.
[21:06:09] <JT-Shop> then you move each axis to a match mark and home it and that will be the home position
[21:08:34] <Chris_Bri> thanks for trying to help me. I am reading up as much documentation as I can so that I will understand most of the basic termanology.
[21:11:27] <Danimal_garage> i got a motion sensor to put outside so it rings when someone walks up to my door, now i can catch the douchebags who leave flyers on my door

[21:18:40] <Jymmm> JT-Shop: DCC file transer
[21:19:01] <JT-Shop> what is that Jymmm
[21:19:18] <Jymmm> JT-Shop: Me sending you a file directly, bypassing any server
[21:19:29] <JT-Shop> ah ok
[21:19:50] <JT-Shop> why is it called a chat instead of a file transfer?
[21:19:50] <Jymmm> JT-Shop: If you see DCC Chat, I'm going to assume that's chat directly, bypassing a server too
[21:20:01] <JT-Shop> ok
[21:20:20] <Jymmm> JT-Shop: DCC == Direct Client to Client
[21:20:35] <JT-Shop> that makes sense
[21:20:59] <JT-Shop> I never do that when invited cause I know not what it does/is

[22:00:24] <andypugh> JT California, Canada?
[22:01:17] <Chris_Bri> I did misconfigure the board size... I need to change it from a top left XY co-ord mindset to a center XY co-ord mindset... none of the examples were displaying centered in the board.
[22:02:26] <JT-Shop> Andy yea with a made up zipcode
[22:02:35] <andypugh> Top-left is fine for machine zero, you just need to touch-off to set up a working coordinate system centred at a point of your choosing
[22:02:36] <JT-Shop> and a 500 error on his homepage link
[22:03:00] <andypugh> See what happens, they might be genuine.
[22:03:24] <andypugh> Unlikely, and it looks suspicous, but still.

[22:04:18] -!- e-ndy has quit [Quit: Ex-Chat]
[22:05:52] <cpresser> Chris_Bri: since this is a gantry i would suggest to have XY zero in one of the corners. this makes the math for aligning pieces much easier :)
[22:05:53] <andypugh> Though top-left might mean that your Y axis is inverted.
[22:06:44] <cpresser> also having the zero-point next to the home-switches safes you a little time when staring up your machine
[22:07:02] <Danimal_garage> it's the mach guys trying the trojan horse technique
[22:18:51] <Danimal_garage> some guy has been burning down cypress trees in about a 4 block radius in my area
[22:19:00] <Danimal_garage> it's been going on since 2009
[22:19:17] <Danimal_garage> they got the guy on camera doing it, yet they still havent gotten him
[22:19:28] <Danimal_garage> nut job
[22:19:56] <Chris_Bri> Hey... Cypress trees may have killed his whole family...
[22:20:16] <Danimal_garage> ha
[22:20:42] <Danimal_garage> they are sort of rad condominiums, i bet he's trying to scare people into cutting them down since there's so many rats around here
[22:29:16] <PCW> andypugh yes they are our names not necessarily EMCs names
[22:31:00] <PCW> also the 7I76 firmware needs updating (SPINDIR and SPINENA changed to boolean type)
[22:31:43] <andypugh> I wonder if I should use a look-up table to convert to the (widely ignored) EMC2 convention. Probably not, it is more important to match the Mesa docs than a hard-to-find EMC2 doc.
[22:32:03] <PCW> SPINDLE changde units to PERCENT and full scale to 100
[22:32:38] <andypugh> What's the difference between boolean and bits? They will probably both be HAL "bit" pins
[22:32:57] <PCW> NO the device should be self documenting there should be no string matching ever ever ever
[22:33:35] <andypugh> Do you mind if I change to lower-case "i" in 7i69?
[22:33:41] <PCW> boolean is a single bit (but the variable may be a byte, word double etc)
[22:33:57] <PCW> The 7I69 ID is wrong?
[22:34:21] <Chris_Bri> With certain font types I and 1 look the same
[22:34:43] <andypugh> It is 7I69. EMC2 names the cars with a lower-case "i", so 7i69
[22:35:06] <PCW> I guess a to-lower is OK
[22:35:41] <PCW> just no card or name specific code since they may all change
[22:35:50] <Chris_Bri> So you guys work with EMC and car manufacturing?
[22:36:20] <andypugh> Card, I can't type
[22:36:43] <Chris_Bri> k.

[22:37:50] <JT-Shop> under all this stuff
[22:37:59] <Chris_Bri> I am getting off work now. peace.
[22:41:29] <PCW> Oh booleans: so if a boolean is read if the byte,word,double is non zero its true
[22:41:31] <PCW> sending out a boolean measn send 0 for false and all 1's for true (so a byte true boolean is sent as 0xFF)
[22:42:30] <andypugh> Ah, so I need to send the right width?
[22:42:43] <PCW> this is different from bits because a parameter with type bits and size byte is a array of 8 bits
[22:42:59] <andypugh> Do 7i70 and 7i71 need a power conection to communicate like the 7i76?
[22:43:08] <PCW> Yes
[22:43:36] <PCW> 7I69,7I70,7I71,7I76 manuals are on the web page now
[22:43:59] <andypugh> So far only the 7i69 talks to me, so I am not clear on the general case.
[22:44:55] <PCW> 7I70,7I71,7I76 have isolated I/O all powered by field power
[22:44:56] <PCW> (and processor is powered by field power as well 8-28V)
[22:45:37] <andypugh> OK, so no comms without power, as no processor?
[22:45:39] <JT-Shop> PCW: did you get the 7i76 done?
[22:45:52] <PCW> unfortunaly your 7I76 needs it firmware updated to have the proper boolean type for its SPINENA AND SPINDIR
[22:46:01] <PCW> Yes and sent

[22:49:31] <PCW> Its possible to update the firmware on the 7I76 with Windows or DOS
[22:49:47] <JT-Shop> neat
[22:50:07] <norias> howdy
[22:51:05] <PCW> but slightly painful with window sine th e7I76 has a TTL level serial port

[22:56:20] <PCW> What V?
[22:58:33] <PCW> 1 is TB1 bottom pin?
[22:59:11] <andypugh> I was just turning up the V, it only got to about 1V
[22:59:34] <andypugh> Yes, pin 1, square pad, black wire, 2 gaps, red wire.
[23:00:27] <PCW> is the manual wrong? V+ goes to bottom pin (1) and V- to top (8)

[23:06:58] <PCW> I'm pretty sure they were shipped that way
[23:07:08] <andypugh> OK. Looks like my policy of setting the voltage then turning the current to zero is a good one.
[23:08:03] <PCW> Well we have a 3A diode but maybe you supply could fry it if i can output 10 or more amps
