[00:16:26] <MacGalempsy> andypugh- hows it going?
[00:17:05] <andypugh> It is going very late :-)
[00:17:51] <MacGalempsy> hey got a question for you. i got the lenovo m57 you thought might work, but the pci mesa card wont allow the machine to boot.
[00:18:01] <MacGalempsy> have you come across this problem before?
[00:18:54] <andypugh> Maybe
[00:19:19] <andypugh> I have found right-angle riser cards that won't let the machine boot.
[00:19:23] -!- micges [[email protected]] has joined #linuxcnc
[00:19:30] <MacGalempsy> not using that
[00:19:53] <MacGalempsy> the pci card worked in my dell workstation
[00:21:51] <andypugh> I am not the chap you want on this one, you want PCW or pcw_home
[00:22:49] <MacGalempsy> the only thing I have come across is that ibm had crippled this machine to only work with with select pcie cards, so maybe they did that here too.
[00:26:39] <andypugh> Seems unlikely.
[00:27:02] <andypugh> There may be BIOS tweaks you could try, though I have no idea what.
[00:27:39] <andypugh> Is there anything interesting in dmesg?
[00:27:56] <andypugh> (I suspect there might not be if it won't even boot)
[00:28:31] <cradek> what do you mean by won't allow the machine to boot? what do you see?

[00:51:01] <Meduza> Hi everyone, I'll am trying to set up a cnc mill with a mini-itx card and a cnc4pc c10 breakout board, but I have the problem that I get no output signals at all
[00:52:50] <Meduza> I have a logic analyzer hooked up to the output of the c10 card on the step/dir pins, but neither running the axes in axis or testing to toggle the pins with ptest.hal
[00:53:09] <Meduza> Gives any output
[00:53:15] -!- jfire has quit [Ping timeout: 248 seconds]
[00:53:21] <Meduza> Inputs works perfectly
[00:53:37] <Tom_itx> do you have a driver loaded for it in the config?
[00:53:50] <Tom_itx> i'm not familiar with that card
[00:53:55] <Tom_itx> i use mesa
[00:54:26] <Meduza> It is just a generic buffered breakout for parport
[00:54:48] <Meduza> So only parport drivers loaded
[00:55:07] <Meduza> Standard stepconf install
[00:55:14] <Meduza> Setup*

[01:46:18] <somenewguy> I should , but my network is slow and I keep forgetting to write down the syntax
[01:46:37] <somenewguy> for a while I thought you HAD to use numbers, no letters allowed, was a little distraught
[01:48:55] <micges> its simple
[01:48:56] <micges> numbered - #4711
[01:48:56] <micges> named local - #<localvalue>
[01:48:56] <micges> named global - #<_globalvalue>
[01:49:09] <jdh> if it eventually loads, I would assume something just generated too many iterative movements. But, I don't see it.

[07:26:38] <mrsun> when cutting a taper, its very important to be exactly on center with the tool ?
[07:26:52] <mrsun> in the lathe
[07:27:29] <MacGalempsy_> that would make the most sense
[07:27:45] <MacGalempsy_> or else your taper would be off centered
[07:29:13] <archivist> it would not be the taper you want
[07:29:22] <archivist> curved I think
[07:29:30] <mrsun> thinking like when indicating a tapered thing.. if you are not on exact center of the taper the it will be off
[07:31:21] <archivist> I like my taper turning attachment :)
[07:31:37] <mrsun> =)
[07:32:02] <mrsun> but you still need to have the tool on exact center to be able to turn an accurate taper with that ? :)
[07:32:12] <archivist> yes
[07:32:41] <mrsun> but how to find the exact center... more then putting a piece in and facing it and adjusting until i get no spiggot in the center
[07:34:18] <archivist> or compare to a centre in the tailstock
[07:34:37] <archivist> nice pointy one
[07:35:21] <mrsun> yeah, got a new dead center i usaly do that with but its hard to see imo =)

[11:09:03] <MacGalempsy_> or is it better to stick with one brand?

[17:06:52] <CaptHindsight> IchGuckLive: you missed the discussion
[17:07:06] <CaptHindsight> I use NX and sometimes solidworks

[17:08:00] <JT_Shop> http://www.qcad.org/en/qcad-downloads-trial

[17:08:12] <JT_Shop> it also exports g code
[17:08:17] <JT_Shop> but I can't get it to work
[17:09:34] <IchGuckLive> nice
[17:09:55] <IchGuckLive> it needs a Acad r12
[17:10:54] <PetefromTn> Apparently it is just 2d stuff. You can use draftsight for free and it is autocad clone works great.

[17:12:24] <CaptHindsight> heh, when I just tried to run it I first looked for how to extrude and rotate.... but hey this is only 2D :)
[17:12:36] <PetefromTn> hehe...
[17:13:30] <PetefromTn> is PCW around?
[17:14:20] <pcw_home> yep
[17:14:40] <PetefromTn> Hey man howyadoin?
[17:14:57] <PetefromTn> Got some good news. dunno if you heard or not.
[17:15:29] <PetefromTn> remember yesterday we were discussing the spindle noise issue popping some errors on my cincinatti Arrow 500 VMC?
[17:16:15] <jdh> you can extrude in draftsight
[17:16:48] <PetefromTn> After talking to you about it and discussing grounds and ground loops I decided to go out there and look at the ground situation on the machine. While poking around and inspecting the grounds on the Hitachi 15HP VFD I found nothing.
[17:17:27] <Tom_itx> it would likely be 2d
[17:17:48] <PetefromTn> However When I poked around at the long multi position screw terminal ground strip I found a single tiny wire that was not hooked up. Seems it was an original wire from the old control that had two wires into a single crimp
[17:17:54] <jdh> until you extrude it.
[17:18:17] <Tom_itx> will it extrude the z data?
[17:18:33] <jthornton> draftsight exports g code?
[17:18:52] <Tom_itx> the problem with cutter paths is you never end up with the solid you would have started with
[17:19:10] <PetefromTn> I guess one of the wires I used to go ground one thing and the other went somewhere else to ground something else and they both went under the same ground terminal. Well one of the wires pullled out. I checked where it goes and reinstalled it into another ground terminal and now my spindle on and off errors seem to be gone!!!
[17:19:17] <jdh> jt: no
[17:19:47] <PetefromTn> No draftsight exports dxf or dwg etc. files for import into Cam.
[17:20:30] <pcw_home> Well if the VFD isn't grounded, the return current from the PWM switching in to the motor
[17:20:31] <pcw_home> capacitance will happily travel down the DB25 cable to the PC causing havoc...
[17:20:35] <jthornton> no reason to add an extra cog in the wheel
[17:20:38] <Tom_itx> i should start a gcode export service :)
[17:20:53] <pcw_home> glad its working now
[17:21:33] <CaptHindsight> PetefromTn: every used machine I ever get has wiring problems
[17:21:36] <PetefromTn> Yeah man I am REALLY glad because those errors were ANNOYING! The VFD WAS grounded and I used heavy cables for that...
[17:22:48] <PetefromTn> CaptHindsight: Yeah but this machine has been completely gutted and I installed all brand new motors and drives and computer etc. I just re-used some of the original low voltage wire to do the new stuff back there and this one wire has a dual crimp into the same terminal. One just popped out is all and I did not find it for awhile.
[17:23:50] <PetefromTn> pcw_home: Yeah man I would STILL like to test out that isolation board you were telling me about it might help me to avert future problems..
[17:24:57] <PetefromTn> CaptHindsight: Even the wiring harness between the new motors and drives is all brand new and made by the manufacturer. The only thing left original in this VMC is the spindle motor and some of the toolchanger electronics and pneumatics.
[17:26:27] <CaptHindsight> must have been frustrating
[17:26:33] <jthornton> PetefromTn, is your spindle motor an AC servo?
[17:27:14] -!- maximilian_h1 has quit [Quit: Leaving.]
[17:27:31] <PetefromTn> jthornton: No it is a very large three phase AC motor that HAD a resolver for feedback which I am gonna change out for a nice encoder I bought for it at some point so I can rigid tap again.
[17:28:14] <PetefromTn> CaptHindsight: Actually it was MUCH easier than the last retrofit I did which was on a manual mill. The basic three axis machine only took about a month to get running.
[17:28:15] <jthornton> ok, mine is a Siemens AC servo and I need to put a vector drive in there I understand
[17:28:35] -!- kwallace1 [[email protected]] has joined #linuxcnc
[17:28:44] <PetefromTn> jthornton: Yeah that is what I am using, a large derated vector drive. Hitachi 15hp.
[17:29:03] <PetefromTn> jthornton: what machine?
[17:31:03] <JT_Shop> BP Discovery 308
[17:32:00] <PetefromTn> Hmm interesting that smaller machine has a servo spindle.

[17:46:14] <PetefromTn> So far so good!!
[17:48:24] <jdh> I have one AD PLC. The ethernet communication to it is flakey.

[20:21:59] <false> andypugh: that sucks man
[20:22:22] <false> They weren't able to reattach?
[20:23:15] <andypugh> It's nothing serious, just wore (or burned, can't even recall) the fingertip smooth.
[20:23:34] <false> Oh, you removed the fingerprint?
[20:23:35] <andypugh> It will grow back.
[20:24:01] <andypugh> Yeah. The finger is still fine.
[20:24:06] <false> I thought you meant you cut it off completely :P
[20:24:28] <false> that would really get in the way of your hm2 activities
[20:24:43] <andypugh> That would be bad. More by good luck than good judgement I do still have all the sticky-out bits :-)
[20:24:48] <false> which we so desperately need.
[20:25:15] <false> That's true for most of us, once you're on auto-pilot things go wrong
[20:26:18] -!- c60 has quit [Quit: leaving]
[20:26:47] <false> andypugh: I'm writing a hal component for my toolchanger, is there an easy way to set the current tool from inside a comp?
[20:27:21] <false> Or do I need to modify my iocontol to accept an update flag like in the triac_changer comp?
[20:28:02] <andypugh> You want something to spot that you have changed tools and update LinuxCNC to suit?
[20:28:26] <false> I couldn't find a rw hal pin that contains this information.
[20:28:37] <andypugh> I am pretty sure that there isn't one.
[20:28:49] <false> Yes
[20:29:29] <false> I can get around this but I thought let's ask, maybe I'm missing something
[20:29:30] <andypugh> Do you anticipate this happening when the machine is in Auto?
[20:29:39] -!- jasen_ has quit [Quit: Page closed]
[20:30:11] <andypugh> What would work (out of Auto mode) would be an MDI_COMMAND that runs an M61 to update the tool-in-spindle.
[20:30:40] <andypugh> So, MDI_COMMAND creates a HAL pin, then that triggers a G-code sub that reads a value from HAL and does a G61...
[20:31:03] <andypugh> Not elegant, but ought to work.
[20:31:25] <false> I'll keep that in mind
[20:32:01] <andypugh> My approach is to have a screen of buttons, and if I do my own tool change I tell the system which one I put in.
[20:32:44] <andypugh> But I was thinking of systems that detected which hole in the tool rack was empty, and did it automatically.
[20:33:10] <false> If I do a manual toolchange that's what I do to, for tools that are not normally in the ATC I use numbers above 1000 and check for this condition on startup
[20:33:50] <false> Well I can do that with this atc, but there could be 25 tools in the atc (full) and a tool in the spindle from doing some manual
[20:35:46] <false> So the way I do this right now is: Turn on machine -> home xyz -> home atc -> ask which tool is in the spindle -> rotate to pocket on atc. If a tool is present an error is thrown, the atc shifts two pockets so that the offending pocket is at manual removal position. Then after removing the offending tool I can retry the toolchange from the GUI
[20:36:58] <false> This is also the procedure while in auto mode, if a tool is present it rotates and waits for user input. It then rotates back to the tool pickup position and checks for tool presence/absence again.
[20:37:50] <false> This is also extra safety because there is no "tool present" sensor on the spindle, just clamp locked/unlocked
[20:40:45] <false> quick question: can I use abs function inside a comp?
[20:40:48] <andypugh> Tool-present ought to be easy enough to arrange. (I assume that the pull-stud sits higher when the spindle is empty)
[20:41:17] <andypugh> Yes, though you might have to include a library to get it
[20:42:26] <andypugh> The "abs" function doesn't use it.
[20:42:56] <false> sorry didn't get that last part
[20:43:21] <andypugh> The "abs" HAL component doesn't use abs
[20:43:28] <false> Ah, ok
[20:43:52] <false> It checks below zero and then multiplies by -1?
[20:44:02] <andypugh> Yeah.
[20:44:07] <andypugh> I tend to use v = (v < 0) ? -v : v
[20:44:38] -!- Laremere has quit [Ping timeout: 264 seconds]
[20:44:42] <false> Is that quicker in terms of exection time?
[20:45:06] <andypugh> Probably slower, but you can be sure it will work.
[20:45:30] <andypugh> abs is for ints, there is absf (or fabs, I always forget) for floats.
[20:45:58] <andypugh> But you may need to #include rtapi_math.h to get them.
[20:46:01] <false> I come form C# so I'm a little spoilled
[20:46:35] <false> but in terms of speed nothing beats c pointers
[20:47:01] <false> blisteringly fast :P
[20:47:36] <false> * included
[20:48:42] <andypugh> You can use the ternary operator in places where you would use the abs function, too. ie. q = 32 * abs(v) can be written as q = 32 * ((v < 0)? -v : v)
[20:49:43] <andypugh> Comp has an undocumented feature, you can specify includes, "include" before the ;; does it.
[20:50:15] <false> like so: ?
[20:50:19] <false> #include rtapi_math.h
[20:50:22] <false> blalbal
[20:50:24] <false> ;;
[20:50:36] <andypugh> Just be aware that the C-code is compiled from a temporary file that is not in the same part of the tree as the .comp file
[20:50:54] <andypugh> No, you don't want the # if it is before the ;;
[20:51:18] <andypugh> Though you _can_ use the # _after_ the ;;
[20:51:30] <false> right, here is where my knownlege of C lacks :P
[20:51:44] <andypugh> This is a _comp_ quirk
[20:51:59] <false> Ah, that's to keep it interesting
[20:52:39] <andypugh> the comp script converts the .comp file to C-code in a temporary location, then compiles it.

[20:58:17] <MacGalempsy> hello
[20:58:46] <MacGalempsy> got a new pc and the latency test is running. anyone help me out how to run glxgears? first time linux user here
[20:59:30] <Loetmichel> MacGalempsy: open a terminal window and type "glxgears" and return ;-)
[20:59:56] <andypugh> false: Which you use depends on if you need the #includes in the setup code/
[21:00:33] <MacGalempsy> excellent Loetmichel things are looking good
[21:00:38] <false> macgalempsy: open a terminal and type "glxgears" without the quest
[21:00:41] <false> quotes
[21:00:49] <andypugh> false: It can be instructive to compile the comp into C (that's one of the options) and see what ends up where in the file.
[21:01:02] <false> andypugh: I will do that
[21:01:12] <MacGalempsy> thanks. servo thread 32000 and base thread 19000
[21:01:15] <MacGalempsy> abouts
[21:01:32] <false> leave it running at least 24 hours

[21:05:18] -!- odogono has quit [Quit: odogono]
[21:07:45] <MacGalempsy> ok. will run 24 hours. after that I will do permanent install
[21:07:57] -!- EvanM has quit [Ping timeout: 250 seconds]
[21:08:02] <false> macgalempsy: also make sure you use the "isolcpu" feature if you have a multi core cpu. You can check if your settings for isolcpu work by opening your system monitor, if it worked only cpu 1 should show activity, the other one(s) should be flat lines
[21:09:23] <false> cpu 0 that is
[21:10:12] <Tom_itx> andypugh, on a rotary tool changer the empty hole stays indexed until the next tool change
[21:10:18] <Tom_itx> that wouldn't apply to a belt system
[21:10:39] <Tom_itx> which will prefetch the tool and place the old one in it's place
[21:11:02] <andypugh> Tom_itx: Are you referring to the idea for my rack? That's just a physical rack, made of wood :-)
[21:11:17] <CaptHindsight> try running STRESS and heavy Java and Flash laden web pages while running the latency test
[21:11:59] <MacGalempsy> do I type stress into the terminal?
[21:12:02] <Tom_itx> i was reading the scroll on tool changers ( i thought ). i'm kinda outta it atm
[21:12:14] <Tom_itx> i did see your tool rack
[21:12:34] <CaptHindsight> MacGalempsy: you might have to install the Stress package first
[21:14:23] <Tom_itx> on a belt system i suppose the first time you load the tools, T1 will be in the T1 slot but once it starts prefetching and returning tools the order would be scrambled on the belt so the machine would need a tool table for that
[21:14:48] <false> CaptHindsight: I'll remember that one
[21:15:19] <andypugh> Yeah, that's the "Random Toolchanger" option.
[21:15:26] <MacGalempsy> CaptHindsight: ok installed what kind of settings?
[21:16:14] <CaptHindsight> MacGalempsy: if you use too much memory the system will start using Swap
[21:16:51] <Tom_itx> one of our Okumas was like that, the others had the rotary changer
[21:17:40] <Tom_itx> oh and the old boss 5 had the tools laid out on the table in sequence :)

[21:18:27] <CaptHindsight> MacGalempsy: stress --cpu 8 --io 4 --vm 2 --vm-bytes 128M --timeout 100s
[21:18:32] <MacGalempsy> the example is stress --cpu 8 --io 4 --vm2 --vm-bytes 128M --timeout 10s do these look good?
[21:18:41] <MacGalempsy> ok that is what is running
[21:18:51] <CaptHindsight> MacGalempsy: that will run for 10 seconds
[21:19:20] <CaptHindsight> you can change the timeout to 1000 or 10000 to run for much longer
[21:19:27] <CaptHindsight> top
[21:20:07] <CaptHindsight> running top will also show you how much memory and cpu you are using to change the parameters
[21:21:01] <MacGalempsy> should stress run the entire 24hr test?
[21:22:37] <CaptHindsight> MacGalempsy: you can and it's going to tax your whole system including finding out if your cpu heatsink and power supply are adequate
[21:22:39] <MacGalempsy> also, what is a good java website to stress things to the max?
[21:22:59] <CaptHindsight> we have lost 1 or 2
[21:23:20] <MacGalempsy> i just want to make sure the box wont freeze up when machine a complex part
[21:24:13] <andypugh> I think that my 12V supply in my mill keeps dropping out. This is bad, because it mainly feeds the PC.
[21:24:21] <CaptHindsight> with the right settings you can run all your cores at 100% and use up all your RAM
[21:24:35] <Tom_itx> andypugh, did you ever receive those chinese regulators yet?
[21:24:43] <Tom_itx> smps
[21:24:43] <CaptHindsight> the system will get as hot as it will ever get
[21:25:34] -!- ingsoc has quit [Ping timeout: 246 seconds]
[21:25:37] <andypugh> Yes, I have a bunch of the step-downs and the step-ups eventually arrived too. And work nicely for waking up an 8i20 from my 30V lab PSU.
[21:25:49] <CaptHindsight> MacGalempsy: I'm not sure how 6you have your BIOS settings now but we generally kill all the power management so we really find out how hot the system is going to get
[21:26:01] <Tom_itx> makes you wonder how they can make them for that price
[21:26:06] -!- jfire has quit [Quit: Leaving.]
[21:27:44] <MacGalempsy> so far both max jitters are about the same 32000
[21:28:51] <CaptHindsight> MacGalempsy: I've had systems that ran great except for ~1 time per hour there would be some event that jumps to 100K or more
[21:29:39] <MacGalempsy> CaptHindsight: so with servos and a mesa card, the base thread is the most important?
[21:30:05] <CaptHindsight> MacGalempsy: with servos is much less an issue
[21:30:18] <CaptHindsight> but yes
[21:30:59] <andypugh> Currently I have a 2kW 24V supply, and that runs one of these:
http://www.ebay.co.uk/itm/290686270849 to make the 12V for the PicoPSU in the PC. But it is running pretty hot. So, I might try one of these instead:
http://www.ebay.co.uk/itm/200960509542 as I have them, and whilst lower-rated than the others, might prove better.
[21:31:54] <MacGalempsy> what is the significance of the max interval?
[21:33:37] <CaptHindsight> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?TweakingSoftwareStepGeneration
[21:34:18] <Tom_itx> andypugh, your psu doesn't draw more than 3A?
[21:34:46] <andypugh> It's a D510 with a small SSD and no fans.
[21:35:05] <andypugh> Though I guess I should put an ammeter on it :-)

[21:37:12] <Tom_itx> http://www.mini-box.com/60w-12v-5A-AC-DC-Power-Adapter
[21:37:17] <Tom_itx> there's a little smaller one
[21:37:43] -!- ingsoc has quit [Quit: Leaving.]
[21:37:59] <Tom_itx> the bigger one has a small fan inside iirc
[21:38:42] <Tom_itx> yes, - Has a small fan, starts only at high load
[21:38:50] <andypugh> I already have 2kW of 24V. Seems daft to add a whole extra PSU
[21:39:07] <Tom_itx> probably so, i didn't have one at the time
[21:39:40] <Tom_itx> but with the hdd mine draws a bit more
[21:39:54] <andypugh> Mx load configuration for the D510MO is 50W, min load is 25W, so the 3A converter is a bit stretched.
