[00:02:37] <atom1> JT-Shop, i got the G54 set but when i manually change tools and write the new offset to the table it remains at zero
[00:02:52] <atom1> after reloading the tool table...
[00:03:12] <atom1> T10 M6 G43
[00:03:22] <atom1> jog to height and touch off to the table
[00:03:41] <atom1> T1 M6 G43 jog to new height and touch off to the tool table
[00:03:49] <atom1> both are zero
[00:05:03] <atom1> Touchoff to workpiece is selected
[00:05:48] <atom1> mm just a sec i may have figured something out here

[00:09:28] <JT-Shop> atom1, you seem to be skipping around and I can't keep up
[00:09:36] -!- sumpfralle has quit [Read error: Operation timed out]
[00:09:41] <atom1> start from the beginning then
[00:09:43] -!- Nick001-Shop has quit [Remote host closed the connection]
[00:09:45] <atom1> i'll follow
[00:09:56] <atom1> if you have time that is
[00:10:08] <JT-Shop> ok say I'm setting up T1 and T2
[00:10:24] <atom1> using G54 offset.. ok
[00:10:58] <JT-Shop> first load the tool with T1 M6 G43
[00:11:11] <JT-Shop> then make sure touch off to fixture is selected
[00:11:40] <atom1> ok i thought you said touch off to workpiece at first
[00:11:48] <JT-Shop> now set tool 1 from say the vise jaw and make sure Z axis is selected
[00:11:49] <atom1> i selected fixture... go on
[00:12:01] <JT-Shop> then touch off the tool table
[00:12:23] <JT-Shop> now load tool 2 in the spindle and do a T2 M6 G43
[00:12:38] <JT-Shop> set the Z on it the same way as you did the first
[00:12:54] <JT-Shop> touching off to the tool table each time.
[00:13:07] <atom1> select the z axis from where?
[00:13:10] <JT-Shop> now change the touch off to workpiece
[00:13:26] <atom1> the tool table?
[00:13:28] <JT-Shop> on the manual tab make sure Z is the selected axis
[00:13:28] -!- iwoj has quit [Quit: Computer has gone to sleep.]
[00:13:38] <atom1> oh ok, it is
[00:13:57] <JT-Shop> if you have X selected then you will touch off X not Z
[00:14:05] <atom1> right
[00:14:15] <atom1> i got that part. my G54 x y and z are all set
[00:14:16] <JT-Shop> ok, now both tools are set to a common point for Z
[00:14:24] <JT-Shop> g54 is not set yet
[00:14:30] <atom1> alright
[00:14:47] <JT-Shop> you have only set the relationship between the two tools in the tool table
[00:15:13] <atom1> where does axis indicate what tool is selected?
[00:15:19] <atom1> or does it?
[00:15:26] <JT-Shop> now load tool 1 with T1 M6 G43 and making sure that touch off to workpiece is selected
[00:15:32] <JT-Shop> bottom bar
[00:15:37] <JT-Shop> or the DRO tab
[00:15:38] <atom1> ok
[00:15:42] <atom1> yeah
[00:15:56] <JT-Shop> now touch off G54 to the workpiece
[00:16:10] <atom1> ok lemme catch up here
[00:16:23] <JT-Shop> now when you load tool 2 and do a G0 Z0 it will be the same Z as tool 1
[00:16:33] <JT-Shop> ok
[00:17:59] <atom1> when setting the tools does it matter if i jog first or select the tool first before writing the value?
[00:18:49] <JT-Shop> doesn't matter so long as the correct axis is selected before you touch off
[00:18:58] <atom1> just checking
[00:19:29] <r00t4rd3d> how do you select the tool out of the tool table?
[00:20:07] <r00t4rd3d> normally when i do something it says No Tool at the bottom
[00:20:08] <JT-Shop> in g code?
[00:20:19] <r00t4rd3d> what if i dont know how
[00:20:26] <JT-Shop> Tn M6 G43
[00:20:31] <r00t4rd3d> why is the tool table in there if i cant use it?
[00:20:48] <JT-Shop> dunno why you can't use it
[00:20:52] <r00t4rd3d> i should be able just click on one
[00:21:04] <r00t4rd3d> check box, use this tool
[00:21:20] <JT-Shop> you can, you just have to program that in
[00:21:51] <atom1> JT-Shop, both tools show zero in the Z offset in the tool table after setting them
[00:22:13] <atom1> and reloading the tool table...
[00:22:23] <JT-Shop> are they the same lenght
[00:22:29] <atom1> no
[00:22:50] <JT-Shop> you have done something wrong or missed a step somehow
[00:23:31] <atom1> ok, 1) tool touch off to fixture is selected
[00:23:48] <atom1> 2) T10 M6 G43
[00:23:56] <atom1> 3) jog to point
[00:24:07] <atom1> 4) Touch off to table
[00:24:20] <atom1> 5) T1 M6 G43
[00:24:27] <JT-Shop> touch off to T?
[00:24:28] <atom1> 6) jog to point
[00:24:33] <atom1> yes
[00:24:50] <JT-Shop> stop and look at your tool table for tool 10
[00:24:53] <atom1> 7) touch off to T again
[00:25:02] <atom1> before or after reloading it?
[00:25:04] -!- taiden [taiden!~luke@cpe-184-153-132-154.maine.res.rr.com] has joined #linuxcnc
[00:25:11] <taiden> evening gents
[00:25:17] <JT-Shop> you don't have to reload the tool table
[00:25:23] <JT-Shop> unless you manually edit it
[00:25:35] <taiden> so im having an interesting problem
[00:25:35] <atom1> maybe that's what i'm doing wrong
[00:25:39] <atom1> it may be zeroing it from the file
[00:25:50] <atom1> lemme try once more
[00:25:50] <taiden> it's probably my own doing tbh
[00:26:04] <taiden> i have a subroutine that cuts a circle, quite simple
[00:26:09] <taiden> it's in my subroutine folder
[00:26:14] <taiden> when i call it from MDI it works perfectly
[00:26:20] <r00t4rd3d> lol Digg just sold for 500k
[00:26:32] <taiden> but when I call it from within an *.ngc file
[00:26:49] <taiden> axis preview shows that the circles are about double the diameter as intended
[00:26:59] <taiden> and it gives me massive warnings when it ry to run it anyway
[00:27:18] <taiden> i'm not passing it variables
[00:27:28] <taiden> the subroutine uses all locally scoped variables
[00:29:29] <atom1> JT-Shop, do i need to enter the value from the DRO display in the dialog box before writing the tool table?
[00:29:44] <atom1> or is it stored in a var automatically
[00:29:50] <JT-Shop> I use 0 when I touch off to a fixture
[00:30:08] <atom1> i'm still working on the tools
[00:30:29] <JT-Shop> set one then look to see if the tool table has changed
[00:30:44] <atom1> it didn't
[00:31:52] <atom1> it changed to red and said it had been updated by an outside source
[00:32:42] <ReadError> http://i.imgur.com/5v6bH.jpg
[00:32:44] <ReadError> i cut it again
[00:32:46] <ReadError> less depth
[00:32:50] <ReadError> think it turned out better
[00:33:01] <ReadError> i need to tweak some stuff still
[00:33:12] <atom1> ok after reloading it, it was different
[00:34:48] <JT-Shop> yea you don't really want the tool table editor open when you touch off to the tool table
[00:35:20] <JT-Shop> taiden, it's impossible to guess without more information
[00:35:37] <atom1> JT-Shop, ok they both have non zero numbers in them
[00:35:46] <atom1> now to the G54 offset
[00:35:47] <JT-Shop> YEA!
[00:36:03] <atom1> so are those values relative to machine zero?
[00:36:09] <JT-Shop> yea
[00:36:19] <atom1> so they will always be negative
[00:36:28] <JT-Shop> usually for Z
[00:36:38] <atom1> just verifying what i see
[00:36:42] <JT-Shop> make sure you have touch off to workpiece selected
[00:36:59] <atom1> ok so for the tools you touchoff to fixture
[00:37:10] <atom1> and for the offsets you touchoff to workpiece?
[00:37:10] <taiden> alright it appears to be only a rendering issu
[00:37:29] <taiden> because it runs fine
[00:37:35] <taiden> but axis freaks out whenever i try to run it
[00:37:42] <atom1> JT-Shop, ok touchoff to workpiece is selected
[00:38:05] <atom1> T2 is still active
[00:38:15] <JT-Shop> if your using a dowel then enter that diameter in the touch off window
[00:38:20] <atom1> (per your example)
[00:38:23] <JT-Shop> when you touch off
[00:38:45] <atom1> well i offset it in my cad so i don't need that
[00:38:54] <atom1> i can use zero there
[00:39:00] <JT-Shop> ok
[00:39:08] <atom1> you follow that right?
[00:39:28] <JT-Shop> yea, a bit prone to mistakes at least for me
[00:39:29] <atom1> i just lower the model in my cad by the offset value
[00:39:39] <atom1> it's how i've always done it :)
[00:39:54] <JT-Shop> should be good for you then
[00:40:03] <atom1> ok carry on..
[00:40:27] <atom1> so enter the G54 offset value using any tool?
[00:40:36] <JT-Shop> yea
[00:40:48] <atom1> it says it's zero right now
[00:40:51] <JT-Shop> each tool has been set to each other
[00:40:56] <taiden> anyone have any ideas why axis is rendering my subroutine wrong?
[00:41:31] <JT-Shop> load tool 1 and move to the same Z position and it should be 0 too
[00:41:54] <atom1> i can verify that by subtracting the offset difference between the 2 tools in this case
[00:42:01] <atom1> ok
[00:42:56] <JT-Shop> I never look at the tool table
[00:43:15] <atom1> heh

[00:43:28] <atom1> you can sometimes spot obvious mistakes there
[00:43:34] <atom1> i jogged and it's right
[00:44:08] <JT-Shop> I spot my obvious mistakes by loading the tool and jogging to a known postion then look at the dRo
[00:44:32] <atom1> so in review, touch to fixture to set the tool offset and touch to workpiece to set the z zero fixture offset
[00:44:34] <atom1> ?
[00:45:25] <atom1> i was manually editing the table but it wasn't set from machine zero, rather from the tool offset difference
[00:45:36] <atom1> that's where i went wrong
[00:45:42] -!- iwoj has quit [Client Quit]
[00:45:54] <JT-Shop> sounds right
[00:45:59] <atom1> and not having the right touch off selected in the Machine menu
[00:46:08] <atom1> alright, i'll run a test and see
[00:46:20] <JT-Shop> ok
[00:46:21] <atom1> well above the material

[00:49:40] <JT-Shop> well I have one button that performs the touch off to material for me
[00:49:58] <atom1> does it write to the tool table?
[00:50:01] <JT-Shop> that way I don't have to remember to do anything
[00:50:05] <JT-Shop> yep
[00:50:31] <atom1> select the tool, jog to position and push the button?

[01:06:36] <Tom_itx> i need a tool rack now with all my preset tools
[01:06:54] <Tom_itx> grab a tool, select it, set the fixture offset and go

[01:07:21] -!- Thetawaves has quit [Client Quit]
[01:07:24] <Tom_itx> in theory that should work though
[01:08:07] <taiden> i like to lower my Z onto a block of known height and then tighten up the chuck

[01:08:16] <taiden> i'm trying to figure out how to do that in a program with multiple tool changes
[01:08:31] <taiden> emc2 wont let me jog with the tool change dialog up (probably for good reason)
[01:08:46] <taiden> and by lower my z i mean lower my tool

[01:10:16] <Tom_itx> taiden you might ask andypugh when he comes back, i think that may be something he was working on to add
[01:11:19] <Tom_itx> but unless you have separate tool holders like i do and enter the values in the tool table you would be better off splitting the program up by tool

[01:15:31] <JT-Shop> don't think so, Les did something a while back but it is not really practical to do so
[01:15:47] <Tom_itx> hmm i'd have sworn i heard andy talk about it
[01:16:04] <JT-Shop> my touch off to material button just runs a mdi command so it is really simple
[01:16:23] <Tom_itx> G10?
[01:16:52] <Tom_itx> i forget.. G10 L2 something something
[01:17:26] <JT-Shop> MDI_COMMAND = G10 L20 P1 Z0.375
[01:18:35] <JT-Shop> you just make a pyvcp button to execute a halui.mdi.command...
[01:18:42] <Tom_itx> yeah
[01:19:01] <r00t4rd3d> i wish i knew what you guys were talking about
[01:19:13] <Tom_itx> i did that once for my fixture home
[01:19:19] <Tom_itx> i like it
[01:19:37] <Tom_itx> i got a feeling i'll be adding more buttons soon
[01:19:57] <Tom_itx> maybe a whistle or two

[11:18:31] <jthornton> you don't need permission to ask a question
[11:18:51] <iguru> Okay, I'll just ask it then. Is there any reference to the kernal used in the latest release? I am having issues with a network controller as it does not seem to detect the network card.
[11:20:14] <jthornton> wifi?
[11:21:08] <Valen> some intel nic's need a poke before they switch on, though networkmanager should be doing that by itself
[11:22:45] <iguru> Unfortunately not wifi, its a hardwired nic
[11:23:38] <iguru> Atheros Communications Device 1083
[11:23:54] <Valen> you sure about that iguru?
[11:23:54] <jthornton> iirc wifi is more problematic than hardwired in any case all my installations it just seems to work
[11:24:00] <Valen> atheros does wifi stuff
[11:24:33] <iguru> I'm very aware of the setup. it is definitly not a wifi adapter.
[11:24:41] <Valen> no wifi in the box?
[11:24:56] <iguru> Nothing at all. All new hardware
[11:25:14] <Valen> not a laptop or anything like that?
[11:25:36] <iguru> Nope. Custom made PC boxes. New motherboards, cpus etc etc.
[11:25:44] <Valen> ok just checking
[11:26:19] <Valen> wrt your specific question, you can run different kernels, but you need to patch rtai (i think) into it and recompile EMC against the new kernel
[11:27:52] <Valen> what version of the kernel are you running?
[11:29:02] <iguru> 2.6.32-122-rtau
[11:29:05] <iguru> 2.6.32-122-rtai*
[11:30:04] -!- sumpfralle1 has quit [Ping timeout: 248 seconds]
[11:30:38] <iguru> I'm using the linuxcnc distro. I have a feeling I might need to manual install ubuntu then install the linuxcnc packages. Unfortunatly I've been thrown in the deep end on this one.
[11:31:02] <iguru> I'm aware there is an issue because of the need for a realtime system.
[11:31:06] <Valen> i'd avoid that if you can
[11:31:08] <jthornton> the wiki has instructions for that
[11:31:19] <Valen> it probably wouldn't solve the issue
[11:31:27] <jthornton> but the LiveCD should be the same
[11:31:37] <Valen> the "easy" way around it is a $30 intel NIC
[11:31:44] <jthornton> Valen, do you think the hardware is too new for 10.04?
[11:32:16] <iguru> @Val I would agree but my boss has 5 of these machines already bought and expects me to make magic happen -_-
[11:32:18] <Valen> looking at this http://ubuntuforums.org/showthread.php?t=1677122
[11:32:52] <Valen> iguru: sure at $150 its not a cheap fix to put an intel nic in? ;->
[11:33:26] <Valen> it looks like going less than 2.6.34 poses some challenges with that hardware
[11:33:42] <Valen> looks like that guy has done the hard work
[11:33:44] <iguru> I have been researching hence me turning here. I'm not to sure the process that happens when attempting to patch a kernel. I would think I'd lose what I needed the kernel for in the first place
[11:34:47] <iguru> Ahh, I see Valen, I'm taking a deeper read now.
[11:34:55] <Valen> you would be patching the kernel that ships with EMC so it wouldn't be too bad
[11:34:58] <Valen> if it all applies
[11:35:13] <Valen> hmmm actually
[11:35:18] <Valen> no i have it backwards
[11:35:25] <Valen> that guy patched for newer kernels
[11:35:32] <Valen> looks like it should work ok with the older ones
[11:36:22] <Valen> yeah, if thats the case you just need to compile and load that thingo as a kernel module against the current kernel and it should spring into life
[11:37:13] <iguru> I must of poured over at least 15 sites, how I missed this gem I don't know. I shall give it a whirl
[11:37:25] <Valen> mmm hang on that one
[11:37:45] <Valen> i think that patch is for running the drivers with a later kernel
[11:37:53] <Valen> which you don't need
[11:38:05] <Valen> have you found the actual drivers provided by atheros somewhere?
[11:39:00] -!- karavanjoW has quit [Ping timeout: 244 seconds]
[11:40:04] <iguru> I have not, or rather I haven't attempted to. When reading through the errors that people had with the nic in question I found that the solutions always pointed to a kernel change
[11:40:27] <Valen> it sounds like atheros at one stage provided drivers
[11:40:42] <Valen> but from kernel 2.6.38 they were built in
[11:42:08] <iguru> yes that my understanding as well.
[11:43:24] <iguru> My main concern was in altering the linuxcnc distro, I think though if I can get this to init without issue I'll be good to go.
[11:43:34] <iguru> or rather the kernel

[11:43:59] <Valen> my concern is going to a .38 kernel requires rtai compiling against it
[11:44:32] <Valen> although actually it sounds like it does
[11:45:40] <iguru> You don't think it can be installed without altering the kernel? We are running a kernel lower than the one mentioned. If I can get hold of the drivers then I should be able to swing it.
[11:46:10] <Valen> that would be how I'd prefer to do it if i was you

[11:53:13] <iguru> and i'm back, are we looking for the vendor id?

[12:29:54] <Tom_itx> i haven't tried one

[12:30:40] <iguru> I should of seen that one coming.
[12:30:44] <taiden> it's so cute!
[12:30:45] <Tom_itx> yeah i got mine just to try, i'm actually using a cheap hdd
[12:31:04] <Valen> that said SSD's are stupidly fast
[12:31:10] <taiden> they are
[12:31:12] <Tom_itx> that too
[12:31:12] <taiden> but i dont need the speed
[12:31:15] <taiden> was thinking of dust
[12:31:17] <iguru> Thank you for the assistance, after finding the correct driver download, didn't have any problems
[12:31:19] <Valen> if you can get a 32gb one for the same price as any size hdd i'd get the SSD ;->

[12:31:45] <Tom_itx> bill him $100/hr
[12:31:45] <Valen> make sure it supports TRIM though
[12:32:07] <Valen> i subcontract for somebody, I found what they were billing the client
[12:32:12] <Valen> friggin $180/hr

[12:32:31] <taiden> how much ram are you running?
[12:32:33] <Valen> catchya
[12:32:39] <Valen> I have 2gb
[12:32:48] <Valen> i'd put more in if the board could handle it
[12:32:48] <Tom_itx> you only need 2g i have 4
[12:32:52] <Tom_itx> 2 is plenty
[12:33:08] <Valen> atoms are kinda underpowered, more ram should help with "snappy"
[12:33:17] <jdh> underpowered for what?
[12:33:30] <Valen> just general use
[12:33:35] <Valen> i mean they are ok, we use one

[12:36:55] <taiden> oh my cd drive is ata
[12:37:02] <taiden> will that work with the atom board?
[12:37:02] <jdh> heh... google says they are now
[12:37:14] <Valen> you want to keep the rest of the computer without dust

[12:37:57] <archivist> I was running a buildbot slave for a while on the P4 and did cut gears at the same time, only had 2gm iirc
[12:39:58] <skunkworks> I am using one of the first gen intel atom boards (dual core) for a media machine (xp 1GB ram) and it is on the edge
[12:40:21] <Valen> skunkworks: using vdpau?
[12:40:43] <archivist> this box Im on suffers from dust bunnies
[12:40:45] <Valen> also what media player?
[12:40:49] <skunkworks> heh - no. Just vnc
[12:41:00] <Valen> vlc?
[12:41:14] <skunkworks> vnc for remote access and vlc for playing
[12:41:51] <Valen> I got a zotac ion, with onboard 9300 nvidia
[12:42:08] <Valen> so i can offload all the video playing onto that
[12:42:40] <jdh> I played a tiny clip on my rasberry pi the other day. Looked fine.
[12:44:32] <Valen> I wish the pi supported hw accel of mpeg2 and some kind of lvds
[12:44:41] <Valen> finding displays is hard
[12:44:45] <Valen> (small ones)
[12:45:00] <jdh> for $35, don't expect much.
[12:45:26] <jdh> I plugged mine into my 56" teevee. Amusing watching linux boot
[12:45:27] <Valen> the board supports both of those, its just not paid for or not broken out
[12:45:50] <Valen> we have mythtv box connected to our tv ;->
[12:46:00] <Valen> mythtv = linux pvr

[12:53:16] <taiden> any tips on sata cables
[12:53:20] <taiden> right angle or not
[12:54:16] <skunkworks> if you need right angle...
[12:54:49] <Valen> oh btw, most atom boards probably wont have a pata connection
[12:54:57] <mozmck> the right angle slows the electrons down...
[12:55:01] <skunkworks> heh
[12:55:17] <mozmck> some fly off the corner so you lose data :)
[12:55:22] <skunkworks> or the don't stop and shoot right out of the corner
[12:55:30] <skunkworks> heh
[12:56:01] <skunkworks> I think that only happens in high power RF
[12:57:35] <Valen> sata spec says that you should expect a bit error when you fill a 1Tb hdd
[12:57:47] <mozmck> Yeah, I'm kidding. I don't think it makes any difference for sata.
[12:58:02] <mozmck> one bit error?
[12:59:37] <taiden> haha
[12:59:52] <taiden> i really dont want to spend $220 on a computer
[13:00:16] <taiden> but i really really really dont want mine to crash in the middle of cutting product
[13:00:27] <Valen> as in if you put 1Tb of data to disk, one of the bits will be wrong
[13:00:37] <jdh> $220 sounds so miniscule for a computer.
[13:00:44] <jdh> but, I'd rather not spend it if I didn't have to either.
[13:00:45] <taiden> it is
[13:00:47] <Valen> $220 is a pretty cheap computer lol
[13:00:58] <taiden> it s more that i dont want to spend $220 on anything :)
[13:01:03] <jdh> Valen: only 1 bit?
[13:01:08] <Valen> aparently
[13:01:19] <Valen> presumably you would have another one when reading it
[13:02:06] <r00t4rd3d> today is friday the 13th
[13:02:13] <r00t4rd3d> MUAHAHAHAHAHAHA!
[13:02:34] <Valen> only for another hour
[13:02:37] <Valen> anyway bbl

[13:08:55] <taiden> Tom_itx: did your atom board come with sata cables?
[13:09:04] <jdh> mine did
[13:09:19] <jdh> I have a hundred or so spares if you need one.
[13:09:30] <taiden> did it come with 2? just trying to decide if i need to buy any
[13:10:00] <jdh> 2. I only use the HD though
[13:11:07] <taiden> did you install from usb stick?
[13:11:31] <jdh> yes
[13:12:25] <taiden> hmmm
[13:12:48] <taiden> is that trivial?
[13:13:06] <jdh> sure. And speedy.
[13:13:15] <jdh> directions are on the web page
[13:13:17] <taiden> "burn" iso to usb disk and go?
[13:13:22] <jdh> yeah
[13:13:27] <taiden> neat
[13:13:45] <taiden> would it handle multiple partitions with different LiveCDs installed?
[13:13:56] <taiden> or is that a little too smart for it to handle
[13:14:03] <jdh> it is the same as booting the livecd off cd
[13:14:18] <taiden> i will skip my cd drive then
[13:14:23] <taiden> saves me $20. thanks!
[13:15:22] <taiden> so now i can get my computer tomorrow for $205

[13:52:07] -!- iguru has quit [Quit: Bye Bye]
[13:57:55] <jdh> I have some code where multiple rungs set/reset the same bit. The 'last' rung is supposed to win, but it doesn't seem to always be the case.
[14:02:08] <JT-Shop> bad idea to try and have the same output on more than one line
[14:02:44] <jdh> yeah. it's ancient code. Bad from a style point of view. Shouldn't make any difference to the PLC though
[14:02:54] <JT-Shop> I got some strange results last night from some ladder that gave me some experience
[14:03:11] <JT-Shop> depends on the plc, I've been finding out some are a bit different
[14:03:50] <archivist> the coder in me asks if on same line which happens first

[14:04:21] <jdh> single output per line
[14:04:40] <jdh> but, one rung can have multiple output lines (depending on the plc)
[14:05:01] -!- Thetawaves [Thetawaves!~Thetawave@7-139-42-72.gci.net] has joined #linuxcnc
[14:05:37] <JT-Shop> yep, and some can have multiple outputs on one line
[14:05:52] <jdh> never seen one of those.
[14:06:02] <jdh> but, I have limited vendor experience.
[14:06:50] <JT-Shop> Panasonic you can do some wild stuff, but it is GUI magic as it all boils down to the basic ladder code
[14:07:25] <jdh> do you use grafcet for anything?
[14:08:04] <JT-Shop> Panasonic has it but I've never had a reason to use it
[14:09:12] <JT-Shop> err, no it has Sequential Function Chart and Structured Text programming as well as Ladder
[14:10:14] <jdh> I (coworker actually) had a similar problem with a Festo PLC. Turned out it is harder to store the program than he thought (ram vs. eeprom)
[14:10:23] <JT-Shop> as well as a couple more like Function Block Diagram and the all time favorite Instruction List
[14:10:45] <jdh> we have almost all GE PLC's, they have those too, but we only do ladder
[14:10:50] <JT-Shop> yea, those kind of things can really give you a headache
[14:14:12] <skunkworks> I tried having 1 output in 2 places in classic ladder.. It doesn't work well ;)
[14:14:50] <jdh> why not?
[14:15:02] <jdh> it should evaluate sequentially and do the right thing
[14:15:49] <anonimas1> that's why it's a good idea to have a output task with a ladder statement/st that evaluates them
[14:15:55] <archivist> er what, two outputs in parallel means a fight
[14:16:13] <jdh> I have never seen parallel outputs.
[14:16:15] <anonimas1> we do it that way all the time, in general paralell access on the same line means you are up for interesting bugs.
[14:16:33] <jdh> well, they look parallel, but one comes after the other
[14:16:56] <anonimas1> im telling you they dont evaluate properly all the time
[14:17:17] <jdh> inconsistent, or just consistently not what you expect?
[14:18:19] <anonimas1> it works, it's just not very safe, and if you have a multithreaded plc it's more fun :p
[14:18:50] <anonimas1> and sometimes a io can lock up in a unknown state until the next cycle.
[14:19:02] <anonimas1> because of being overwritten.
[14:19:26] <anonimas1> wrapping is easy and safe, and it also lets you override whatever you did if you need a software estop hooked up.
[14:20:07] <anonimas1> ie, so you have a single task on the plc override everything else for the io so you are 100% sure that when you request a stop you do not have a bit toggled in some sub-task
[14:20:42] <anonimas1> tho it depends on how you handle states in your project i guess.
[14:25:44] <JT-Shop> what anonimas1 said
[14:26:27] <JT-Shop> it's kind of like using an undocumented feature that may work a lot but may not work sometimes
[14:27:02] <anonimas1> hell even documented are sometimes not doing what expected
[14:27:21] <anonimas1> if you ever move to a newer plc, and they swap out the firware versions you might get problems also

[18:45:53] <Diony> I encountered some problem with gladevcp. I want to run python mdi script (probe) when I push the button called "run" and simulate the probe contact with an other button. The gladevcp freeze during the probe python script execution.
[18:46:13] <Diony> Someone here already get this problem?
[18:47:25] <pcw_home> gene77 is this a spindle speed control?
[18:47:42] <Diony> no a z probe script
[18:48:29] <pcw_home> that was for gene77
[18:48:43] <Diony> sorry
[18:49:33] -!- ve7it has quit [Remote host closed the connection]
[18:50:41] <gene77> Yes Peter. I just took the I gain from .01 to .02 which seemed to be just a hair much but usable.

[18:51:53] <gene77> And I am usiing that error, integrated thru a lowpass to set the trigger points

[18:54:59] <mhaberler> so where exactly is the surprise - you c&p some code from somewhere and it blocks - so?
[18:55:07] <pcw_home> gene77: do you have FF0 about right? that will help the overall tracking

[18:55:40] <gene77> FF0 is about 45, pgain 100
[18:56:03] <pcw_home> Yeah you shoud tune FF0 by it self first
[18:56:30] <Diony> and I don't know how to make it respond
[18:56:30] <mhaberler> so you expect it 'not to freeze', I assume
[18:56:57] <pcw_home> (assuming this is a voltage mode drive = Hbridge or just PWM)
[18:56:59] <Diony> yes because I use a sim-probe button
[18:56:59] <gene77> And I need to restrict the high end as it comes out of axis, it is asking for more than the controller/motor can do, so that can trip me off too.
[18:57:10] <Diony> on the same panel
[18:57:12] <gene77> pwm
[18:57:21] <Diony> (test purpose)
[18:57:39] <pcw_home> yeah so FF0 does your BEMF
[18:57:55] <mhaberler> Diony: this is some code I tried, and dumped. I do not use it. It just happens to be on the web, and I have no plan to support it.
[18:57:57] <Diony> Do you a an idea how to proceed?
[18:58:09] -!- ve7it has quit [Remote host closed the connection]
[18:58:13] <gene77> set Igain to zip & tune with FF0?
[18:58:21] <Diony> ok no problem with supporting this probe code
[18:58:25] <pcw_home> Yes
[18:58:36] <gene77> I'll try that, bbs
[18:58:49] <pcw_home> (P and I to 0) FF0 is open loop
[18:58:56] <Diony> In fact the probe code works well from terminal

[19:00:09] <mhaberler> your best bet is to use an oword sub, and call it from the MDI action widget, see the manual
[19:00:47] <mhaberler> if you insist on using my python code, see http://git.mah.priv.at/gitweb/emc-mill.git/blob/HEAD:/emc_control.py , in particular the wait option on method g(self,code,wait=False):
[19:01:31] <Diony> I understand what you mean
[19:01:59] <Diony> but my question is about using gladevcp asynchnously
[19:02:03] <Loetmichel> sooo, got the SPS-chip... the second cheap TB6560-board is back to running, too... *note to self: must remember to change the Capacitor to a 50V type, so this wont happen again* -> http://youtu.be/ZyqRfDE__HQ
[19:02:31] <andypugh> Diony: Did we already talk about this, or was that someone else?
[19:02:33] <Diony> I already use this code through your probe code
[19:03:11] <mhaberler> so fine, what exactly does 'asynchronously' mean - you queue an MDI command, and then what?
[19:03:38] <Diony> andypugh: no It was me, soory to annoy you
[19:04:17] <mhaberler> if you read lines 92-100 of http://git.mah.priv.at/gitweb/emc-mill.git/blob/HEAD:/emc_control.py you see how it waits for gcode completion
[19:04:51] <andypugh> No worries. It just means there is no point me trying to track down if the other guy figured it out.

[19:06:01] -!- dimas_ has quit [Ping timeout: 246 seconds]
[19:06:38] <educa> Dear people. Can somebody please tell me if there is something like a ramp angle built into linuxcnc ? I mean if I want to do 2 G01 moves after eachother or for example mill out a circle made up of 100 lines, then without ramping angle the stepper motors would ramp up and down for every single line in that circle, but because the angle between 2 lineai moves is so small it can actually continue at full speed without negative effect
[19:06:40] <gene77> That seems to work at 46, the integrated error stays under +- 1.0 until I hit the top of the controller at about 1100 revs.
[19:06:43] <educa> doet linuxcnc do that ?
[19:07:29] <educa> doet=does
[19:07:36] <gene77> Just specify the end point of the ramp for the 2nd axis on the same command line
[19:07:59] <gene77> it will draw as smooth as you can do
[19:08:10] <educa> nono I don't mean that
[19:08:19] <educa> look, if you make a circle with 100 lines
[19:08:22] <cradek> I'm not sure what implementation detail you're describing, and it doesn't matter really, but linuxcnc does constant velocity transitions between segments in situations where it can
[19:08:28] <educa> then theoretically thats 100 times a ramp up and down
[19:08:29] <andypugh> educa: I think you might be talking about G64?
[19:08:41] <educa> no
[19:08:49] <educa> I'll try to explain differently
[19:08:53] <JT-Shop> educa, G64 Pn
[19:10:27] <educa> I currently use winpcnc for my cnc milling machine and it has to ramp up and down of course, but if that controller sees that between 2 G01 lines there is an angle less then 30° , then he doesn't ramp down and up between these moves and continues at full speed
[19:10:41] <educa> and I'd like to get rid of winpcnc :) and use linuxcnc
[19:10:49] <JT-Shop> educa, G64 Pn
[19:11:32] <JT-Shop> educa, please read this page http://linuxcnc.org/docs/html/common/User_Concepts.html

[19:12:24] <JT-Shop> not G64 but G64 Pn

[19:14:16] <educa> So to say, if I have a G1 X100 Y100 F3000 followed by a G1 X200 Y110 then linux cnc will also ramp up and down the 2 moves individually, but with G64P0.05 it would not ramp down ?
[19:14:20] <Diony> mhaberler: It's hard to explain it to you, in fact I want to build a short of "mdi-script-deamon" which is running in background and use gladevcp to drive it.
[19:14:46] <Diony> and display results
[19:15:08] <mhaberler> what is the point? master supports queued execution of MDI properly since a few weeks
[19:15:45] <Loetmichel> educa: it will ramp down. but not to full stop, only so that it can drive a circle with 0.025mm radius on the edge safely
[19:15:46] <JT-Shop> educa, http://linuxcnc.org/docs/html/common/User_Concepts.html#_programming_the_planner
[19:15:54] <Loetmichel> and thats what it makes fast
[19:16:06] <mhaberler> the interpreter does have an input queue for MDI
[19:16:06] <Diony> The point is queued MDI is no interractive (apart Oword)
[19:16:11] <Loetmichel> (if you write P0.05 after the G64)
[19:16:17] <educa> JT-Shop, i'm reading it right now, looks interesting
[19:16:28] <educa> tnx
[19:16:35] <JT-Shop> ok, that is important to read
[19:16:57] <mhaberler> I do not understand what you mean by 'non-interactive'
[19:17:09] <mhaberler> what is missing?
[19:18:24] <Diony> you need to know exactly all your MDI command at the begining
[19:18:55] <Diony> queued it and during the process you can't change it
[19:19:33] <mhaberler> the execution of a block is atomic if you will - what would you want to change during execution of a block?

[19:20:09] <mhaberler> please give an example what you want, and cannot do now
[19:20:36] <Diony> I am writing some code to make transformer coil with EMC2
[19:21:18] <Diony> So I wound magnet wire layer by layer
[19:22:06] <Diony> I don't know exactly the size of the layer (depending on many parameters)
[19:22:37] <Diony> and need to be adjust "in live" during the first layers
[19:23:14] <Diony> I though code with G38
[19:23:30] <Diony> and virtual probe limits
[19:23:42] <archivist> as the wire comes from a distance, what does the diameter matter
[19:23:48] <mhaberler> how does the adjustment happen - are these computed values, entered by user?
[19:23:51] <andypugh> Are you sure it makes any sense to use G-code for this?
[19:24:43] <archivist> I can see where some ocodes could make an easy coil winder
[19:25:00] <Diony> The first layer is wound slowly without limits
[19:25:35] <gene77> One more question; is the pwm generator disabled instantly when estop is exerted, or does it ramp down, I have a lowpass element in front to control the startup accelleration
[19:25:56] <Diony> when the operator see the first layer is full, he set the right limit of the windows
[19:26:16] <mhaberler> you mean spindle stop, set size etc?
[19:26:19] <andypugh> gene77: It depends on what the pwmgen.enable is wired to.
[19:26:30] <Diony> then he wound the second layer and set the left limit
[19:26:59] <Diony> it is no spindle an "A" axis
[19:27:03] <archivist> Diony, you know the wire width and bobbin width, machine should know a full layer ish
[19:27:38] <mhaberler> I assumed a lathe, but fine
[19:27:46] <andypugh> This might be a job for something like WillemCMD has set up, a system with just a GladeVCP GUI and HAL components, but no G-code intepreter.
[19:28:21] <Diony> archivist: yes sure in theory, but in real the wire guide i not very precise
[19:28:25] <archivist> ols style coil winders have auto reverse that the operator sets mechanically
[19:29:00] <gene77> motion-spindle-on
[19:29:12] <mhaberler> the whole thing is a case for spindle synced motion to start with, not for a probe
[19:29:20] <mhaberler> like threading
[19:29:37] <andypugh> gene77: Then the PWM will stop instantly. The filter may take some time to run down, though, and the drive too.
[19:29:52] <Diony> archivist: yes you are right, but you need to adjust this
[19:30:12] <Diony> archivist: during the first layers
[19:30:21] <archivist> I have a coil winder rotting in the back garden :)
[19:30:24] <gene77> Sounds good, and yes that interface takes a while to run down
[19:30:25] <mhaberler> HOW: again, what happens when "the operator see the first layer is full, he set the right limit of the windows"
[19:30:43] <mhaberler> does she stop the spindle, enter some values, does a switch trip?
[19:31:04] <andypugh> So, how about a GUI with a button that populates a "finish angle" scrolllbox, that can then be tweaked up and down during subsequent layers to suit?
[19:31:13] <Diony> mhaberler: I use a simple "G1 X10 A36000" by layer (or G38...)
[19:31:18] <archivist> mhaberler, depends if inter layer tape needs fitting too
[19:32:07] <Diony> archivist: So how do you adjust you mecanicals limits?
[19:32:39] <andypugh> I really don't see where probe fits into this at all.
[19:32:48] <archivist> clamp on the reversing shaft hit by the traverser
[19:33:26] <andypugh> Or perhaps I do. You want an "interruptable movement" ?
[19:33:44] <Diony> andypugh: In my gladevcp I avec 2 float values correspondaing at 2 virtual limit switches
[19:33:45] <gene77> Now, if I set the pid.0.Igain too high, this will hide the load error, and I don't want to do that, correct?
[19:34:09] <archivist> traditional machines are foot operated to the hands can be working with scissors etc
[19:34:21] <Diony> andypugh: this virtuals sw are connected to the probe input
[19:35:16] <Diony> so i I saw that my limit is not good during winding, I can adjust them
[19:35:18] <andypugh> gene77: I don't think so.
[19:36:21] <mhaberler> Diony: how is the limit tripped. Do you push a switch, do you abort, press a gladevcp button - I do not understand your process
[19:36:22] <Diony> I am sorry for my bad explanations and english
[19:36:25] <archivist> Diony, add switches that are hit by the traverse s you know extents
[19:36:30] <andypugh> Diony: I think I see what you are doing. You want some G-code which is "expecting" to be interrupted?
[19:36:48] <archivist> then read those in gcode
[19:37:23] <andypugh> I think you might have better luck with a "while" loop making incremental small A moves, followed by the full-speed code.
[19:37:26] <anonimas1> I just bought a spindle speeder

[19:38:00] <anonimas1> :)
[19:38:15] * archivist grmbls :)
[19:38:21] <Diony> mhaberler: the limit is tripped by virtual sw setted in Glade VCP (like sim-home sw in sim emc2 example configurations)
[19:38:42] <mhaberler> aha
[19:38:56] <mhaberler> and that connects to the probe input?
[19:39:07] <Diony> mhaberler: the virtual switch are here to reverse the way of the linear axis
[19:39:31] <mhaberler> yes, fine. Does this button connect to the probe input?
[19:39:35] <anonimas1> we'll see how well it'll eat aluminium with the seco 12mm insert mill
[19:39:39] <Diony> archivist: wath wrong with my virtaul sw?
[19:39:40] <anonimas1> it's rated for 40k tho..
[19:40:00] <archivist> I would use a real switches not virtual probably
[19:40:25] <anonimas1> 2.4m/min of feedrate -_-
[19:40:32] <Diony> andypugh: No the Gcode is simple (successive G38) I want gladevcp responding during the process
[19:41:22] <Diony> mhaberler: yes the 2 virtuals sw are connected to the probe input
[19:41:34] <archivist> Diony, use the gcode to respond, it is in realtime
[19:43:11] <Diony> archivist: I don't understand what you mean?
[19:43:21] <andypugh> archivist: His probe-input is set from the glade GUI, and that is busy waiting for the G38 to finish. But the G38 doesn't finish because the probe input never happens, because glade is waiting.
[19:44:01] <Diony> andypugh: exact! thank you for translating! :)
[19:44:12] <mhaberler> well fine. If you want to do it this way, you have two options: a) monitor the halui.program.is-idle pin to determine execution has stopped b) continously call emcstat.poll in a timer handler (see gladevcp manual for a timer example)
[19:44:49] <mhaberler> py emcstat is not well documented but it will tell you if the command finished, if the probe tripped, and where - I think that is in my code
[19:45:11] <mhaberler> I suggest b
[19:46:10] <Diony> mhaberler: yes, I don't have problem to use emcstat and emccmd
[19:46:12] <andypugh> I think the only problem is the Glade waiting for the probe to finish.
[19:46:28] <andypugh> If it just started it and returned, all might be OK
[19:46:47] <Diony> yes my only problem is making my Gladevcp respond and update
[19:46:58] <mhaberler> well if you just call command.mdi("G38 blabla") it should return immediately
[19:47:12] <mhaberler> the blocking comes from a poll/wait combination
[19:48:03] <Diony> yes but there is many G38... (one by layer until the number of turn is reached)
[19:48:24] <Diony> this can take half an hour
[19:48:47] <andypugh> So, why not handle the probe results in the code triggered by the probe-button press instead?
[19:48:57] <mhaberler> right
[19:49:08] <archivist> what I was saying too
[19:49:52] <Diony> andypugh: sorry I don't understand

[20:07:56] <JT-Shop> the enclosure is not dust tight
[20:08:20] <andypugh> Diony: The limit3 HAL component does all the hard work. You can just feed it end-points.
[20:08:21] <JT-Shop> other than that it looks like a nice package
[20:09:38] <andypugh> Your application does not need a complete G-code interpreter and machine tool control system, so why force such a thing to do your rather different job?
[20:11:22] <Diony> Yes you are right, in fact I use the "A" axis of my small milling machine and a stepper motor to make the spindle
[20:11:56] <Diony> And all the config is done for the machine so it's just a patch on my config
[20:12:34] <andypugh> You can keep several different configurations on the same computer. I can start my multi-purpose machine up as either a mill or a lathe, depending only on the config file.
[20:13:38] <andypugh> A HAL file can load the python gui, and that can be started by the halrun command.

[21:01:12] <andypugh> Jymmm misses the nature of the puzzle
[21:01:31] <Jymmm> GIT ER DONE
[21:03:31] <educa> Got a strange question. A couple of months I installed the livecd of ubuntu 10.04 from the linuxcnc.org site and emc was there by default. Now today I did the same install from livecd (freshly downloaded image) and emc is not there anymore. Do I have to still install it somehow now ?
[21:03:54] <andypugh> I an't choose USB in the boot order.
[21:04:18] <andypugh> educa: Same LiveCD?
[21:04:26] <cradek> educa: there is a bug in the cd that uninstalls linuxcnc (and the realtime kernel) if you have more than 4G (3G?) of RAM in the machine
[21:04:44] <educa> ouch
[21:04:47] <cradek> we will fix it one of these days but meanwhile you can work around it by pulling out RAM or unstalling while the network is unplugged
[21:04:48] <educa> its not same livecd
[21:05:03] <educa> so I better just pull 2GB of ram ?
[21:05:11] <cradek> yes that's the very easy fix
[21:05:14] <andypugh> You can put it back later :-)
[21:05:25] <educa> and it won't uninstall it once 4gb is back ?
[21:05:26] <educa> :)
[21:05:38] <cradek> no it's just during the install
[21:06:00] <Jymmm> wth kinda fscked up bug is that!?
[21:06:14] <educa> the strange stuff is that while evaluating is in LIVE mode all cnc soft is there, its just the installed version where it lacks and only 4 documents are left in the OTHER map
[21:06:20] <educa> anyway, i'll try now with 2GB :)
[21:06:22] <educa> tnx for info
[21:06:23] <cradek> Jymmm: it's a "feature" of the ubuntu installer
[21:06:55] <cradek> ... and we apparently never had enough ram to see it while testing
[21:06:59] <Jymmm> I have too much ram (resources), so let me remove (criple) things. gotcha
[21:07:36] <cradek> to be fair, it's usually what you want, but it messes us up
[21:07:45] <educa> hehe
[21:07:47] <Jymmm> sounds like your your overqualified
[21:07:56] <educa> I'd like to setup emc for a laser cutter using some custom HAL file
[21:08:01] <educa> lets hope it work
[21:08:02] <educa> s
[21:08:24] <cradek> bbl
[21:08:26] <andypugh> It boots from USB if you pull out the CF...
[21:10:02] <educa> While I'm waiting for that install just 1 extra question: When everything is setup correctly then I would like to be able to send out commands from the command line. Like I want to say emc /path/to/my/configfile mygcode.nc and then I just want my stepper motors to move and follow that .nc file. Is that possible with emc ? or do you always get a visual interface like axis ?
[21:10:41] <andypugh> Do I dare just install, or should I try to make a backup image of the CF? (Easier said than done, but might be possible over the network with dd)
[21:11:46] <Jymmm> andypugh: CF is electrically the exact same as IDE
[21:12:37] <andypugh> Jymmm: I don't have anything with IDE either
[21:12:46] <Jymmm> ah
