[00:55:04] <ssi> well that took longer than it should have :P
[00:55:14] <ssi> put a trailer hitch on my car
[00:55:20] <ssi> most of the time was wiring
[00:55:44] <ssi> had to run a power wire up to the battery... meant taking off all sorts of belly aero panels and lots of routing and zipties in tight spots
[00:55:56] <jdh> last few I did the wiring consisted of pulling a plug cover off and putting the wiring harness on.
[00:56:05] <ssi> yeah trucks are good like that
[00:56:06] <ssi> cars not so much
[00:56:16] <jdh> that's because cars don't tow;
[00:56:22] <ssi> sometimes they do!
[00:56:34] <jdh> that's because cars should not tow;
[00:56:40] <ssi> can't imagine why not
[00:57:11] <jdh> crappy transmissions. marginal suspension as it is.
[00:57:44] <ssi> then why's there a towing rating from the mfg?

[00:58:45] <jdh> I think deep down, you agree with me.
[00:59:01] <jdh> maybe not so deep.
[00:59:21] <jdh> so how does your g0602 cut? is it a useful tool for small stuff?
[00:59:27] <ssi> I'm glad that no matter what one tries to do, there's always someone on the internet to tell them they're wrong
[00:59:42] <ssi> g0602's shouldn't cut
[00:59:46] <jdh> and there is pr0n of people doing it.
[00:59:56] <ssi> there are bigger lathes, therefore nobody should ever use a small lathe to cut anything
[01:00:44] <jdh> I sold my meg teeth, got enough to pay for my bicycle and a chinese tool of some sort.

[01:01:30] <ssi> it does fine.. I've even cut rifle receivers and barrels on it
[01:01:40] <ssi> the stock motor blows tho
[01:02:30] <jdh> do you do semi-direct drive with yours?
[01:02:47] <ssi> no I'm using the stock step pulleys
[01:03:23] <jdh> didn't you have a half done g0704 also?
[01:03:32] <ssi> yep
[01:03:37] <ssi> I have lots of half done crap
[01:09:09] <jdh> me too
[01:09:17] <jdh> like my current lathe

[09:07:50] <_abc_> Hello. If I have the ubuntu lts 10.04 based linuxcnc installed on a hdd, will I break axis/linuxcnc if I upgrade only the tcl and tk packages manually to a higher version? I need some features which are not present in the packages on lts 10.04 . I can install from source by hand, but I need to know if it will wreck the linuxcnc install.

[10:34:59] <jthornton> my swag is you can try then if it "wrecks" something you can revert it...
[10:37:30] <archivist> similar to, make part, measure, adjust gcode, rinse repeat till you get a good one

[10:59:27] <Lathe_newbie> hi... have a little question... when i want to select an axis encoder in pncconf, i cant find them, but they are declared in the xml file, can anyone tell me why?
[11:03:45] <jthornton> pncconf is pretty complicated and the only one that understands it is the author and he hangs out in the forum
[11:04:40] <jthornton> Lathe_newbie, what mesa card are you using?

[11:10:51] <jthornton> ok
[11:10:52] <Lathe_newbie> in the .xml file is written Qcount
[11:10:56] <Lathe_newbie> i changed to encoder

[11:15:50] <Lathe_newbie> i have 3 ecoders, they were caled qcount in the xml file... iv i change to encoder, it works
[11:18:22] <jthornton> ah
[11:19:43] <Lathe_newbie> for a selfmade firmware file
[11:19:57] <Lathe_newbie> but there i added 3 ecoders
[11:20:09] <Lathe_newbie> and there was none selectable in pncconf
[11:20:18] <Lathe_newbie> cause they were called qcount and not encoder

[12:41:43] <syyl_> is it rude to say, that it would look better if done freehand with a dremel?
[12:42:45] <CaptHindsight> they ask for criticism/help/advice and then attack you for trying to edify them
[12:43:32] <syyl_> must have a reason why even my manual engraving machine weights about 200kg ;)
[12:44:12] <syyl_> all this make-movement, reprapstuff and "new industrial revolution" thing is nice
[12:44:28] <CaptHindsight> a recent term I've heard to describe machines like yours is "overbuilt"
[12:44:46] <syyl_> ;)
[12:45:17] <syyl_> but nice thoughts dont replace proper engineering or common sense
[12:45:18] <CaptHindsight> the mindset is that it's supposed to be inexpensive and almost work a few times, like HF tools
[12:45:30] <archivist> they are clueless about dynamics, spring of machines etc
[12:45:40] <syyl_> my engraving machine is about 50 years old
[12:45:54] <syyl_> and holds half a thousand without a problem
[12:46:53] <CaptHindsight> try to have this conversation in a channel like #reprap :)
[12:47:15] <archivist> none of the idiots realize the cutting force bends the machine
[12:47:29] <syyl_> no way, CaptHindsight :D
[12:47:39] <DaViruz> oh, that printer deal just friction feeds the board like it was paper
[12:47:47] <syyl_> i may not be an old grumpy machinist
[12:47:54] <DaViruz> i'm sure thats very repeatable after its been fed back and forth a couple hundred times
[12:48:00] <syyl_> but i can be grumpy ;)
[12:48:48] <Tom_itx> archivist, idiots are put here to make us look good
[12:48:50] <archivist> I was making a cd printer using the roller idea 15 years or more ago, roller creep, it is real
[12:49:18] <Tom_itx> and they breed like rabbits
[12:49:48] <CaptHindsight> even the cheap Epson printers have a rack gear molded into the tray for printing CD's
[12:49:56] <syyl_> i want to buld a vmc from plywood, floppy drive steppers and rubberbands!
[12:50:09] <archivist> this was long before the epson did that
[12:50:53] <Loetmichel> hmmm
[12:51:12] <Loetmichel> i would at least uses a 1/8" ball bearing aht that "router bit"
[12:51:19] <Loetmichel> and nor let it run in plastic
[12:51:23] <Loetmichel> used
[12:51:33] <syyl_> i would substitute it by chunk of machine
[12:51:36] <CaptHindsight> http://hackaday.io/project/998-Affordable-Metal-3d-Printer melted his extruder trying to print tin
[12:52:46] <CaptHindsight> yikes "I've taken the RepRap philosophy to heart. There are no swiss-machined parts and crazy Japanese bearings in this machine."
[12:53:19] <archivist> hehe
[12:53:22] <CaptHindsight> no properly fabricated components for me :)
[12:54:16] <Loetmichel> hmmm
[12:54:33] <Loetmichel> i would think the took the 3dprinter philosophy to far
[12:54:40] <CaptHindsight> they wear their ignorance like a badge on their chest
[12:54:45] <Loetmichel> you can only do so much with plastics
[12:54:46] <Loetmichel> ;)
[12:55:13] <Loetmichel> i just happend to get a reprap i3 mechanics kit.
[12:55:28] <Loetmichel> ... fairly useable but could be better
[12:55:49] <archivist> I suppose they will learn the basics, because they will have failures
[12:55:53] <Loetmichel> i am in the process of filing all the dropout filaments and nozzle clogs away
[12:55:59] <Loetmichel> ;-)
[13:02:03] <CaptHindsight> does anyone recall seeing a machine thats acts like hands on clay on a pottery wheel for shaping sheet metal?

[13:02:27] <CaptHindsight> it wasn't like a typical metal spinner with a form that the metal gets pressed against
[13:04:18] <archivist> Ford made a cnc press that uses two wheels to make any tin shape
[13:04:49] <CaptHindsight> sounds similar, yes using two wheels
[13:05:05] <archivist> I saw a a video on TV with some of the operation hidden
[13:05:36] <archivist> effectively a cnc wheeling machine
[13:05:52] <CaptHindsight> might be the one I saw
[13:07:36] <archivist> probably a million patents on the process
[13:07:36] <CaptHindsight> http://www.youtube.com/watch?v=iNQ40MYwZqw here it is
[13:09:49] <archivist> yup, thats the machine, not sure if that was the vid I saw
[13:11:07] <archivist> that looked a bit like a hard stylus/ball bearing pressure point
[13:11:24] <CaptHindsight> same concept as what I recall
[13:12:23] <archivist> ah well, at least our memories are ok....
[13:15:30] <archivist> I think linuxcnc can be coaxed to do that too
[13:16:02] <archivist> the kins for the upper/lower bot probably already exists
[13:17:14] <CaptHindsight> yes, it does
[13:23:38] <archivist> a scroll through and one can see both are the same type, and the narrator calls it a stylus too

[13:27:32] <archivist> I have someone here will have to watch later
[13:28:29] <t12> cool process
[13:29:09] <CaptHindsight> nice way to make low volume formed parts
[13:29:52] <t12> has anyone done PID + resonance filtering in linuxcnc?
[13:31:14] <t12> for servo control
[13:31:25] <CaptHindsight> few use servos
[13:32:39] <t12> i guess it could all just be implemented in the pid module?
[13:32:57] <pcw_home> Theres a biquad filter comp already
[13:33:20] <CaptHindsight> you can modify the source if you wanted to add something non-linear
[13:33:28] <pcw_home> just hang it on the PID output
[13:33:37] <t12> awesome
[13:34:18] <t12> the mitsu encoder support ever go anywhere
[13:34:23] <pcw_home> theres a comp for non-linear stuff also
[13:34:26] <t12> finally getting to messing with this mitsu servo on spindle
[13:34:36] <t12> with the real controller, then want to swap over to 8i20
[13:34:42] <t12> once i get my electronics together
[13:35:29] <pcw_home> theres no hm2 support for it (I dont have one)
[13:36:24] <pcw_home> I still need to get Fanuc type 2 and panasonic supported

[13:58:19] <Lathe_newbie> i think, this is the problem
[13:58:55] <CaptHindsight> have to dig into it
[13:59:47] <CaptHindsight> Lathe_newbie: that was your only change from 2.5.x to 2.6?
[14:00:03] <Lathe_newbie> CaptHindsight: it was
[14:00:11] <Lathe_newbie> but was first run after flashing the 5i25
[14:00:16] <pcw_home> IDROM error of some kind
[14:00:41] <Lathe_newbie> pcw_home: think i should repower the 5i25 completly, not just reboot the computer?
[14:00:55] <CaptHindsight> haven't yet?
[14:01:00] <pcw_home> Yes you must power cycle
[14:01:07] <Lathe_newbie> CaptHindsight: just rebootet
[14:01:29] <Lathe_newbie> but have seen now, that i have to complete recycle, thought that this is done over the pci reset signal
[14:01:35] <CaptHindsight> 1) Did you turn it On and Off yet?
[14:01:45] <Lathe_newbie> no, but now i did and it works^^

[14:07:25] <SpeedEvil> On a related matter.
[14:07:31] <XXCoder> SpeedEvil: yeah. someone must have breathed co2 on it
[14:09:12] <CaptHindsight> it doesn't say how much actual carbon is in it

[16:39:48] <syyl_ws> you would cut your bandsaw in half?
[16:39:50] <Loetmichel> but i would have made a fitting insert that could be bolted to bot ends, so the "ways" are more or less usable again across the wole new length

[16:42:25] <Loetmichel> it just was a bit to short
[16:42:43] <Loetmichel> where is the problem in using a bandsaw to solve that?

[16:44:18] <XXCoder> dunno
[16:44:51] <Loetmichel> that is not so critical in a wood lathe, the railstock only holds a rotating cone so a bit of misalignment doesent do any harm

[16:47:13] <CaptHindsight> he could have made the legs in two parts, saving wear on his bandsaw blade

[18:02:54] <Lathe_newbie> any idea, why this does not work?

[18:03:50] <archivist> I would use a meter/scope to see why
[18:04:19] <Lathe_newbie> CaptHindsight: yes, they should, cause default is 1 on output of the mesa card
[18:05:02] <Lathe_newbie> when i turn the motor axis by hand... it incremets or decrements the actual position in linuxcnc, but it does not work against my manual rotation
[18:05:31] <archivist> is it a dc motor

[18:15:57] <pcw_home> also putting a halmeter on the the PWM value pin should help

[18:18:30] <CaptHindsight> and with sense grounded did you kill the L298?
[18:18:39] <Lathe_newbie> r1 and r2 are 10k

[18:28:27] <pcw_home> also if you connect FPGA output pins to OPTOs with anodes at 5V you need to either enable open drain mode
[18:28:28] <pcw_home> or use a series diode so the 3.3V high output of the FPGA doesn't slightly turn on the OPTO LED when the output is high
[18:28:52] <accuartisans> pcw_home: just to get me started please.
[18:29:27] <Lathe_newbie> pcw_home: so i should connect the outputs other way?
[18:29:57] <pcw_home> no, either use open drain mode or use a diode
[18:30:37] <pcw_home> for the L298 with no enable it probably doesn't matter
[18:31:02] <pcw_home> for a real machine with an enable its critical
[18:31:13] <Lathe_newbie> will build a new drive with ir21844 and mosfets
[18:31:31] <pcw_home> accuartisans: I dont have any real experience with Xenomai
[18:32:28] <pcw_home> all my recent testing is with Preemt-RT
[18:33:19] <accuartisans> pcw_home: that's no problem, just need a generic 3 axis ini, hal for the 7i80/7i77, i don't think the xenomai make a difference for that does it?

[19:00:59] <accuartisans> capthindsight: yes it has to do with the graphics drivers, but i did not know how to integrate the drivers into an older kernel?? what's IIRC?
[19:01:18] <CaptHindsight> if i recall correctly
[19:01:28] <Jymmm> iirc = if I remember correctly
[19:01:33] <accuartisans> :)
[19:01:39] <accuartisans> gotcha
[19:02:30] <accuartisans> capthindsight: i tried ubuntu 12.x and the graphics were terrible
[19:02:47] <accuartisans> capthindsight:were you able to see the config?
[19:03:15] <CaptHindsight> accuartisans: yes, got it, thanks again
[19:03:31] <CaptHindsight> accuartisans: did you build Linuxcnc from scratch?
[19:04:55] <accuartisans> capthindsight: yes from ucb3-7i80 branch
[19:05:36] <CaptHindsight> I want to test it for multitouch and onscreen keyboard
[19:05:47] <accuartisans> capthindsight: you would not believe the hours i have into getting kernel 3.14.4 and xenomai 2.6.3 together!
[19:05:53] <CaptHindsight> heh
[19:06:14] <CaptHindsight> well we spent months on RTAI :)
[19:06:37] <CaptHindsight> bumping it up from 2.6 to 3.4
[19:06:58] -!- ve7it has quit [Remote host closed the connection]
[19:07:00] <pcw_home> Preemt-RT is a 10 minute affair...
[19:07:12] <CaptHindsight> waiting for some fixes to bump it to 3.14 now
[19:07:17] <CaptHindsight> yeah :)
[19:07:55] <CaptHindsight> and Preemt_rt is fast enough for all the fpga boards
[19:07:58] <accuartisans> capthindsight: i have the image and header i can share, i had to modif 5 xenomai header files to get it to compile, i can share those as well.
[19:08:18] <CaptHindsight> anything to help us all get this going
[19:08:35] <CaptHindsight> all your work is definitely appreciated
[19:09:09] <accuartisans> pcw_home: agree!!
[19:09:17] <CaptHindsight> accuartisans: do you have time to create a howto on the linuxcnc wiki?
[19:09:40] <accuartisans> capthindsight: that's my plan
[19:09:45] <CaptHindsight> great
[19:10:36] <Lathe_newbie> like this it should work? http://abload.de/img/drive2hmogs.png
[19:10:44] <accuartisans> pcw_home: thanks for the 7i77 link, i've seen that before, just forgot about it, that should get me started.
[19:11:10] <CaptHindsight> hmm try to save $150 in fpga + stepper IO boards by spending hundreds of hours on RTAI
[19:11:38] <CaptHindsight> that's not the real goal
[19:13:21] <pcw_home> Lathe_newbie: Probably sort of marginal active low is better (either with open drain mode or a diode in series with the OPTO LED)
[19:13:41] <pcw_home> (open drain mode is set in HAL)
[19:17:26] <accuartisans> pcw_home: question what is the default bit file loaded on a 7i80?
[19:17:49] <CaptHindsight> accuartisans: do you get deja-dup-monitor warnings/errors on your 14.04?
[19:18:48] <accuartisans> capthindsight: where would i see that? in the boot up log? I don't recall any of that.
[19:19:03] <accuartisans> i can look in a minute
[19:19:14] <accuartisans> if it's in the log
[19:20:41] <CaptHindsight> accuartisans: are you using Unity?
[19:20:43] <pcw_home> accuartisans: depends on model but I would check (with mesaflash) before connecting anything
[19:21:03] <accuartisans> pcw_home:will do
[19:21:09] <accuartisans> pcw_home:thanks
[19:21:21] <accuartisans> caphindsight:yes
[19:21:33] <pcw_home> (latest mesaflash has a readhmid mode thats lists the pinout)
[19:21:35] <accuartisans> it's not in the kern.log
[19:23:18] <accuartisans> capthindsight: it's not in syslog or Xorg.0.log either
[19:25:09] <CaptHindsight> maybe it's the 3.4.55 causing it?
[19:25:29] <CaptHindsight> only have the problem when 3.4.55 is loaded
[19:25:54] <accuartisans> catphindsight: it's not in dmesg either
[19:26:14] <CaptHindsight> I just removed it
[19:26:28] <CaptHindsight> don't really want a backup monitor
[19:27:38] <accuartisans> pcw_home:btw, i have the 7i80db-25 and a 7i77
[19:30:28] <accuartisans> i'm likely going to have questions when it comes to hooking up these AMC BE25A20 drives, but i'm not ready for that:)
[19:30:42] <pcw_home> that _may_ have been shipped with a 7I77 compatible bit file but I would still check
[19:31:04] <kfoltman> what do you guys use for generating gcode?
[19:31:28] <accuartisans> pcw_home: that's what i'm guessing, but you want me to check without the 7i77 connected, correct?
[19:31:33] -!- ries has quit [Ping timeout: 240 seconds]
[19:31:35] <jthornton> kfoltman, gedit

[19:36:33] <CaptHindsight> pcw_home: using hardware stepping on the 6i25. how poor can a systems jitter be without problem?
[19:37:04] <pcw_home> umm depends on the definition of problem :-)
[19:37:38] <CaptHindsight> hm2 can't function
[19:38:05] -!- ink [ink!~ink@c-71-198-91-97.hsd1.ca.comcast.net] has joined #linuxcnc
[19:38:09] <CaptHindsight> or really to get say 50-100Khz stepping
[19:38:13] <pcw_home> the drivers built in position control loop doesn't do well with more than say 50 usec on a a 1 KHz loop
[19:38:47] <CaptHindsight> so <50us on the 1mS thread
[19:38:57] <pcw_home> but if you use a PID-stepper config, 350 usec or so is tolerable
[19:39:11] <accuartisans> pcw_home: I remember a while back you posted on the forum that there was fix for some kind of timing issue for these new FPGA processors, how would I know if I have the current fix?
[19:39:35] <CaptHindsight> ah ok, we had issues with preempt_rt being over 90K once
[19:40:04] <pcw_home> accuartisans: update the bitfile from the mesa zip
[19:40:39] <accuartisans> pcw_home: That's what I thought I remember you saying, thanks!
[19:40:47] <pcw_home> the problem with the built in position mode loop is it trusts the thread timing more than the hardware
[19:41:12] <pcw_home> (for a hardware stepgen, the opposite is much better)
[19:41:40] -!- ries [ries!~ries@190.9.171.121] has joined #linuxcnc

[19:46:25] <accuartisans> I get to work on this a little, "father's day" and all:)
[19:47:02] <pcw_home> :-)
[19:52:29] <pcw_home> CaptHindsight: so MHz step rates are no issue with 350 or so usec jitter
[19:52:31] <pcw_home> since the jitter just gets low pass filtered away by the PID loop
[19:52:32] <pcw_home> (99.9 percent of the control is just velocity feed forward)
[19:52:34] <pcw_home> and the remaining 0.1% is just a slow feedback loop to correct for
[19:52:35] <pcw_home> minor timebase differences, reversal delays etc
[19:54:05] <pcw_home> the BBB/PRU machine kit people moved to a PID step system in HAL already

[20:11:13] <pcw_home> Yeah the Baytrail chips are very nice

[20:21:09] <CaptHindsight> so new boards should be out shortly
[20:21:36] <CaptHindsight> using FM2 APU's and A88 chipset boards for now
[20:21:47] <accuartisans> capthindsight: what's the processor? better than the 350/450's?
[20:22:07] <accuartisans> capthindsight: Oh! now that should be nice!
[20:22:13] <CaptHindsight> if the superIO is supported on the Biostar then you could port coreboot to it
