[02:13:13] <just_pink> hi
[02:14:37] <just_pink> It was loong day..
[02:23:07] <Deejay> moin
[02:25:52] <just_pink> morning
[02:28:34] <Deejay> hi just
[02:28:37] <Deejay> hi just_pink
[02:35:51] <just_pink> Deejay: [02:51] <just_pink> It was loong day..
[02:36:10] <just_pink> I need to order screws :(
[02:36:37] <Deejay> then do it :)
[02:38:25] <just_pink> i have bag full of nuts ans star washers bot without any data about the thread..
[02:39:31] <archivist> measure, try known bolts
[02:40:01] <just_pink> I think It's 10-32
[02:40:22] <just_pink> I wish I have a tester for threads
[02:41:49] <archivist> I found one on ebay had fun restoring it
http://www.archivist.info/cnc/screw_error/lamp_screw.php
[02:42:46] <archivist> I dont have the accessory for internal threads though
[02:46:29] <just_pink> I want to orde several screws from each thread that exsist.
[02:47:35] <archivist> that is a tall order, there are some rare threads you wont see, and some were specific to the maker
[02:48:25] <just_pink> I mean all the common
[02:50:33] <archivist> get some thread gauges
[02:53:19] <just_pink> http://www.ebay.com/itm/S-W-WALL-MOUNTED-THREAD-CHECKER-SWTC-WM1-/321137442961?_trksid=p2141725.m3641.l6368
[02:54:59] <archivist> http://www.ebay.com/itm/Silver-Thread-Measuring-Gage-Metric-and-Whitworth-Screw-Pitch-60-Degree-55-/321786635306
[02:57:06] <archivist> this one for american thread despite the incorrect title
http://www.ebay.com/itm/ENGLISH-SCREW-PITCH-GAGE-4-84-US-60-THREAD-51-BLADES-/331320676796
[02:57:45] <archivist> and it has thinned down to fit in nuts
[02:58:17] <just_pink> but screw with same tpi will look the same.
[02:58:45] <just_pink> this is why I want to order any screw
[03:01:04] <archivist> I need boxes of bolts,screws and nuts as well as gauges
[03:02:13] <archivist> most kits of fasteners only have popular sizes hence the need to have a gauge to check the rare specials
[03:03:40] <just_pink> I'm order any thread that fastenal have
[03:07:09] <just_pink> I'vesent you in PM
[03:59:25] <andypugh-iPhone> Is it just me? Nothing from the mailing list for 5 days?
[03:59:54] <archivist> sourceforge has had a hugh fsck up in their datacenter
[04:00:58] <archivist> http://sourceforge.net/blog/sourceforge-infrastructure-and-service-restoration/
[04:03:36] <Valen> ouch
[04:04:04] <Valen> they don't actually say what went wrong though :-<
[04:05:46] <just_pink> Insted to make the stak light I've buy one
[04:06:02] <just_pink> just 3 color, red yellow green.
[04:06:37] <just_pink> some oe know about stack light controller?
[04:06:41] <just_pink> one*
[04:08:08] <andypugh-iPhone> This iPhone IRC client is basically unusable, it disconnects if you switch apps or if the phone sleeps. Logging off now.
[04:08:49] <just_pink> anonimasu: OQO
[04:09:04] <just_pink> opss
[04:11:18] <just_pink> ?
[04:11:27] <just_pink> Deejay: archivist ?
[04:55:24] <trentster> howdy all, anyone here used SCHEEBERGER Linear rails? If so opinion on quality?
[04:55:45] <archivist> never heard of them
[04:55:58] <trentster> https://www.schneeberger.com/en/products/linear-bearing-and-profiled-guideways/profiled-miniature-guideway/minirail-mini-x/
[04:56:35] <malcom2073> trentster: I have a set of them sitting in my garage waiting to go on a machine heh, haven't used them yet though
[04:56:58] <XXCoder> new one to me
[04:57:01] <trentster> malcom2073: really - thats interesting, whats the movement of the carriages feel like?
[04:57:04] <malcom2073> Two 2.6 meter rails, and two 900mm rails
[04:57:19] <trentster> malcom2073: you buy new or used?
[04:57:28] <malcom2073> Feels smooth and tight
[04:57:29] <malcom2073> used
[04:57:37] <trentster> if new what was the pricing live vs Hiwin stuff?
[04:57:59] <trentster> what width rails did you get?
[04:58:03] <malcom2073> 30mm
[04:58:41] <malcom2073> Be careful of Hywin, there are a lot of clones that are *really* shitty. If you buy real ones I hear they're not bad though
[04:59:46] <trentster> yeah I think I am going to pull the trigger on the scheebergers, I am sure they will be a hell of a lot better than my current supportedchinese rails on the Z axis
[05:00:56] <trentster> At the moment I am a bit torn about building something from scratch with these rails vs buying a complete unit like a used THK KR33 actuator - opinions?
[05:01:37] <archivist> my machine is mostly second hand crap
[05:01:46] <malcom2073> I love the complete units, I build machines out of them
[05:01:47] <XXCoder> mines first ahnd crap lol
[05:01:51] <XXCoder> *hand
[05:02:15] <malcom2073> I'd say if a used actuator does what you need, no reason to buiild your own
[05:03:07] <malcom2073> Be aware, those actuators (and others like them) are not as sturdy as a set of rails
[05:03:25] <malcom2073> Unless you get the ones that have 15mm thk rails inside :)
[05:03:48] <XXCoder> you start with screwdriver and raw materials. complete an awesome mill.
[05:03:54] <XXCoder> no tool buying allowed
[05:04:02] <malcom2073> XXCoder: pass :P
[05:04:06] <trentster> yeah I am tired of building stuff for the machine and fixing it, I think I have reached the point where I am more interested in just making stuff. Its a hard choice as I can get 6 rails and 12 carriages for the price of 1 x used THK Actuator
[05:04:25] <malcom2073> What length are you looking at?
[05:04:29] <malcom2073> IAI and Parker used actuators are nice too
[05:04:58] <XXCoder> malcom2073: yeah it'd be tough
[05:05:08] <malcom2073> And where are you getting 6 rails and two carriages for $200?
[05:05:09] <XXCoder> maybe easier if buying motors is allowed lol
[05:05:43] <trentster> 12 carriages
[05:05:49] <malcom2073> sorry, 12. Still
[05:06:30] <trentster> http://monosnap.com/image/sLxh83DTAUADmKMt5FMAqp6RUEtRlX
[05:06:51] <malcom2073> Nice
[05:07:49] <XXCoder> sbr rails on side interesting
[05:08:06] <XXCoder> wouldnt it be stronger if force is directed towards supports
[05:13:48] <trentster> malcom2073: actually not nice - its a bit big and bulky - supported rails are bulky
[05:14:16] <malcom2073> True, but slides aren't much less bulkier, they're just significantly sturdier
[05:14:39] <malcom2073> You want bulky anyway, bulk means strength (sometimes)
[05:16:03] <SpeedEvil> More rigidity almost always
[05:17:40] <trentster> you think I did the right thing by making the sliding part of the Z -the taller part with the rails atatched?
[05:18:23] <trentster> 90% of the way most people do it is the other way around with just the ballscrew coupled to smaller plate
[05:18:57] <trentster> it seems more rigid this way at the detriment of the stepper having to work much harder to lift itself and the rails and big plate with every Z movement
[05:20:54] <trentster> XXCoder: hows your build coming along? did you get your linuxcnc PC up?
[05:21:15] <XXCoder> trentster: still havent gotten hard drive for pc but no worries I still has laptop lol
[05:21:32] <XXCoder> it was too hot to build my machine this weekend but got everything ready.
[05:22:16] <trentster> XXCoder: you should boot off the live cd in the interim and run the latency tests and see what kind of scores that pc of yours gets
[05:22:44] <XXCoder> yeah
[05:24:35] <trentster> malcom2073: archivist my above question? if I rebuild the Z do you reccomend swapping that configuration around?
[05:24:57] <trentster> namely rails attacked to non moving part of Z?
[05:28:14] <SpeedEvil> In principle more mass on the z axis is a good thing for smoothing out cutting forces
[05:28:38] <SpeedEvil> If you can handle that mass of course
[05:33:03] <trentster> SpeedEvil: thanks - I thought so. I kinda handle it but have to reduce my Z axis rapid speeds or I will have to get a more powerful nema 23 for Z
[05:34:16] <SpeedEvil> More variable mass at an elevation of course loads x and y too
[05:35:10] <trentster> really?
[05:35:41] <trentster> oh yes of course weight wise
[05:39:54] <SpeedEvil> And lever wise. Moving a mass next to the axis slides vs 30cm up
[05:42:47] <trentster> SpeedEvil: I am not with you - please clarify what you mean?
[05:43:10] <trentster> Are you saying it would be better t have the same heavy weight with a lower center of gravity?
[05:43:54] <SpeedEvil> No, just that high cog does mean torques under rapid x\y
[05:46:37] <trentster> ok I bought them - I hope it was a good buy ;-)

[05:49:09] <trentster> The cnc obsession continues!
[08:29:42] <cradek> lair82: your report doesn't say explicitly so I want to make sure: did you test 2.6.5 and it did not have the problem? i.e. the problem first occurs in 2.6.6?
[08:30:00] <cradek> lair82: (you explicitly say 2.6.4 does not have the problem and 2.6.6 does)
[08:33:35] <lair82> Yes, it did not occur until 2.6.6. I tried every release in 2.6, and it did not occur until 2.6.6, and is in every release thereafter.
[08:33:50] <cradek> ok thanks
[08:34:14] <cradek> that's only 65 changes
[08:36:25] <lair82> Yep, all my turning centers were running 2.6.4, I updated the one to the current 2.6.8, and immediately noticed the problem, went back to 2.6.4 to verify that it was something maybe we just never noticed, and that definitely wasn't the case, there is a delay, checked 2.6.5, no issues, checked 2.6.6, that is where it begins.
[08:37:45] <cradek> well there is only one change to halui between those versions
[08:37:57] <cradek> it looks unlikely to cause this
[08:37:59] <lair82> It will run another 2,3,4,5 lines of g-code depending on how big each move is per line, it is roughly 1 to 1 1/2 seconds on the delay
[08:38:49] <cradek> you could try reverting 149db904c and test that
[08:39:14] <cradek> if that's not it (and I bet it's not) you may have to bisect (which is easy with only 65 changes)
[08:39:25] <lair82> I thought I was losing it for a while, but I have double checked this on 2 different turning centers, and the same problem shows up on each machine.
[08:39:48] <cradek> I believe you that it's real, but that doesn't make me know what the cause is yet :-)
[08:41:21] <lair82> I re-worked my end of the programming, and now am using the motion.feed-inhibit pin instead of the halui pins, and am going to change the other machines as well,
[08:41:42] <lair82> How would I revert?
[08:41:57] <cradek> are you using distributed packages or source builds?
[08:42:18] <lair82> I build from git using the source code,
[08:42:50] <cradek> so you were building the v2.6.5 and v2.6.6 tags for this test?
[08:43:47] <lair82> Yes, I was doing "git checkout v2.6.5" in the linuxcnc-dev directory.
[08:44:22] <cradek> I'm going to try sim+axis+halui here
[08:45:52] <cradek> halui.program.pause / resume work instantly here in 2.6.8
[08:45:54] <lair82> Ok, I don't know how soon I would be able to get to one of our turning centers to try to diagnose further, they are crazy busy right now, so it may be a day or so. Unless we can sort this out on my test pc in my office.
[08:46:11] <cradek> yeah this is going to have to happen in a sim for it to get fixed
[08:46:54] <cradek> there are no relevant changes to halui between those releases, and a zillion changes to gmocappy
[08:47:18] <cradek> so considering that and my sim test, I'm suspicious it's not a halui problem
[08:47:39] <cradek> er gmoccapy
[08:48:55] <lair82> I could tell immediately there was an issue, when we pressed the feedhold pushbutton, I have a red panel mount LED next to the PB, it is connected to the halui.program-is-paused output, and it was delaying on turning on when we pushed the button.
[08:49:03] <cradek> great
[08:49:14] <cradek> then you can easily bisect and find it :-)
[08:52:16] <cradek> yeah there are some harrowing commits here, I'm not going to be able to guess the problem. please concentrate on doing a bisect
[08:52:19] <cradek> cradek@tetrode:~/emc$ git bisect start
[08:52:22] <cradek> cradek@tetrode:~/emc$ git bisect good v2.6.5
[08:52:24] <cradek> cradek@tetrode:~/emc$ git bisect bad v2.6.6
[08:52:27] <cradek> Bisecting: 31 revisions left to test after this (roughly 5 steps)
[08:52:30] <cradek> 5 builds at most will find it
[08:54:27] <lair82> [09:31] <+cradek> cradek@tetrode:~/emc$ git bisect start [09:32] <+cradek> cradek@tetrode:~/emc$ git bisect good v2.6.5 [09:32] <+cradek> cradek@tetrode:~/emc$ git bisect bad v2.6.6 ,,,,, Those are the commands?
[08:54:54] <lair82> Not your stuff, just the git stuff?
[09:00:38] <lkc> Hi there, few days ago I started toying with Lcnc and thought I check on this IRC channel
[09:01:17] <lkc> I havent been using irc like 12 years i guess
[09:01:56] <lkc> Just wanted to say hello
[09:06:34] <SpeedEvil> hey
[09:06:56] <SpeedEvil> It tends to be most active in here from about 2 hours till 12 hours from now.
[09:29:07] <cradek> lair82: a promising looking google hit for how to bisect:
http://stackoverflow.com/questions/4713088/how-to-use-git-bisect
[10:18:10] <Roguish> hey all. guess i've been sleeping for a few days, but what's up with the mailing lists? I haven't received any emails since the 16th ????
[10:18:29] <cradek> sourceforge is all busted
[10:22:07] <archivist> rather buggered
http://sourceforge.net/blog/category/sitestatus/
[10:25:54] <cradek> wonder if the system that ate all their data is the one they migrated to in Dec '14
[10:32:19] <archivist> and rapidly thinking of getting back off it I hope
[10:32:37] <spline> sourceforge blows
[10:32:43] <spline> my god they fucked up that website
[10:32:50] <spline> hijacking projects, injecting malware
[10:42:07] <PetefromTn_> he Malware....why is there even such a thing in the world. Idiots have nothing better to do I guess....
[10:44:57] <cradek> PetefromTn_: because it's profitable in various ways
[10:45:33] <PetefromTn_> It must be there sure is enough of it around.... people will find ways to always screw up a good thing I suppose

[12:06:38] <archivist> there is plenty of support!
[12:07:03] <archivist> just live near someone who can help
[12:08:17] <pcw_home> Not sure any non-exact replacement controller is going to be any easier than linuxcnc unless you pay someone else to install it
[12:11:53] <zeeshan> anyone here clean glass scales before?
[12:12:47] <pcw_home> Ive cleaned glass encoder wheels
[12:14:55] <archivist> I have done an encoder too, carefully, under the microscope
[12:15:23] <zeeshan> can i just blow it with air
[12:16:06] <archivist> might be more crap in your air supply
[12:18:01] <archivist> can be crud on the reader/light source rather than on the scale
[12:19:13] <zeeshan> hmm
[12:19:22] <zeeshan> i guess only way to find out is do it? :)
[12:19:27] <pcw_home> yeah need to clean the scale and the masks in the reader
[12:19:40] <zeeshan> if i take off the scale
[12:19:44] <zeeshan> it seems like a big mission to clean it
[12:19:45] <lair82> zeeshan, I just did a 120" Fagor glass scale a week ago, clean lint free rags, Q-tips and Denatured Alcohol, good as new now.
[12:19:56] <zeeshan> does microfiber towels work ?
[12:19:59] <zeeshan> they are lint free
[12:20:44] <lair82> Probably doesn't matter, just so it's not leaving behind little fibers
[12:21:05] <zeeshan> dfid you have a problem reinstalling the scale?
[12:21:36] <zeeshan> cause it looks like if i remove the scale then it'll be hard to realign it
[12:21:43] <zeeshan> because i won't be able to move the axis
[12:22:05] <lair82> Nope, just have to make sure that the reader is within .005-.010" of parralell both side to side and up and down.
[12:22:17] <zeeshan> howd you ensure that?
[12:22:33] <pcw_home> yeah the reader azimuth adjustment is critical
[12:22:35] <zeeshan> side to side im not worried about
[12:22:43] <zeeshan> because that is already done for me
[12:22:47] <zeeshan> but up and down is adjustable
[12:23:28] <lair82> Place a small dial indicator on the fixed base, next to the reader head as best possible, and jog the table from one end to the other, getting ti dialed in
[12:23:47] <lair82> With the tip riding on top of the scale
[12:24:05] <zeeshan> so iguess you gotta mount the scale pretty damn close first
[12:24:07] <zeeshan> since ull be going it
[12:24:09] <zeeshan> *jogging
[12:24:17] <pcw_home> up and down and side to side are not critical, Azimuth is
[12:24:59] <zeeshan> isopropyl alcohol that you buy in stores
[12:25:00] <lair82> I would check side to side as well, I thought the same thing, and it was out over .030" about half way down, we started getting erroneous following errors, and servo faults just jogging the table 20IPM
[12:25:02] <zeeshan> seems to have oil in it
[12:25:14] <zeeshan> lair82: ah
[12:25:56] <lair82> Fagor recommended Denatured Alcohol for their scales
[12:26:09] <zeeshan> http://dealertraining.cat.com/jobaids/elpdf/eu03dja.pdf
[12:26:38] <pcw_home> if you can measure the analog output of the scale you can adjust for greatest signal
[12:27:13] <lair82> Looks fair enough.
[12:28:41] <lair82> They didn't realize when they originally mounted the scale there was crud on the mounting face, then when I cleaned it and the mounting face, it had the .030" run-out, so I had to shim it back in to get to run properly
[12:30:24] <CaptHindsight> you want to clean the scales and leave as little residue as possible, like most optics
[12:31:39] <CaptHindsight> so try to remove the contaminants vs just move them around
[12:32:51] <lair82> I have a dilemma, we had a PC take a poop last week, machine was about 10 yrs old, been sitting on a turning center all it's life, it has special software on it that communicates with the controllers flawlessly ( Cincinnati Milacron Controls, and their software ) it is DOS based, and I am not sure what OS to put on the new PC I just got done building to replace it. Could I use Ubuntu or Debian to do this? I will post the zip file on
[12:33:00] <lair82> for anyone willing to take a look
[12:34:09] <CaptHindsight> lair82: Linux to run the DOS application?
[12:36:07] <lair82> Here is the link,
http://www.linuxcnc.org/index.php/english/forum/51-ot-posts/29442-operating-software#60800
[12:36:31] <lair82> I don't know, that's why I am asking.
[12:37:42] <sumpfralle> lair82: it surely requires raw access to peripheral devices, or?
[12:38:24] <CaptHindsight> "DCDNC is intended to be a communications program that runs on an IBM PC compatible personal computer. It's purpose is to allow the operator of a Cincinnati Milacron A850 or A950 CNC to transfer part programs between the CNC and the computer."
[12:39:05] <CaptHindsight> This capability effectively transforms the personal computer into an on- line part program storage and management system for the CNC. "
[12:39:35] <archivist> or something like cat file.ngc>ttyN
[12:39:36] <CaptHindsight> it does this over serial
[12:39:54] <sumpfralle> without hardware access, dosbox would be a reasonable choice, I guess
[12:39:54] <sumpfralle> With hardware access maybe you could take a look at freedos? (I never used this one for similar purposes)
[12:40:01] <lair82> That's why the PC has sat on top of the same machine for almost 10 years
[12:48:09] <CaptHindsight> freedos is down since "This sourceforge.net website is temporarily offline."
[12:52:56] <PetefromTn_> I was using a DNC freeware program for the Cinci when I first switched it on and it was barely working. The program communicated fine with the machine tho..
[12:54:36] <PetefromTn_> don't know if there is a market for these items, most are still in original boxes. Please let me know if interested. They are collectables. Antique trains from the 1970's most are still in the original boxes and have never been used or opened too much to list but I will be posting pictures in the next week.
[12:54:37] <sumpfralle> CaptHindsight: "freedos.org" ist down due to sourceforge maintenance (just as other project sites) - the project itself should be alive
[12:54:53] <PetefromTn_> someone just posted that on a local for sale list LOL
[12:55:13] <PetefromTn_> I can imagine there are some guys frothing at the mouth right now in anticipation hehehe
[12:55:15] <PetefromTn_> Hilarious
[12:57:24] <PetefromTn_> that would be almost as good as if it said "Vintage Star Wars collectible toys all in the original boxes and have never been used or opened"
[13:26:42] <lair82> I got freedos burnt to a disc, and is installing now on my pc, see what happens.
[13:50:14] <lair82> That should install on it's own, then I should be able to use it correct? I can't find any directions on installing and using.
[14:02:13] <CaptHindsight> sumpfralle: well that certainly shoots down my Gremlins theory :)
[14:09:32] <rarenickname> I have a file that's been hex dumped then compressed multiple times and I don't know how to decode it to find a password I need
[14:09:56] <cradek> funny story, bro
[14:10:05] <PetefromTn_> heh
[14:10:18] <rarenickname> I don't know I'm new to this :p
[14:11:18] <rarenickname> zcat foobar.bin | bzcat | zcat | tar xO | tar xO | bzcat | tar xO | zcat | file - and that what the I'm supposed to type to get it do give me the password
[14:12:35] <cradek> what on earth are you talking about
[14:12:52] <cradek> and why are you talking about it on #linuxcnc
[14:13:58] <Deejay> 0o
[14:15:18] <rarenickname> lol, I don't know anything about the linux channels and guessed that someone might know about the problem I'm having
[14:21:37] <_methods> is it a burning sensation when you urinate?
[14:21:43] <_methods> i have that too
[14:22:13] <PetefromTn_> oh hell..
[14:22:31] <Deejay> lol
[14:22:33] <Deejay> ymmd
[14:22:37] <_methods> hahah
[14:22:46] <skunkworks_> I don't pee.. I drink just enough liquid that I sweat it out..
[14:23:14] <_methods> they also make a little blue pill that will take care of some other problems in that area
[14:23:25] <_methods> if the problem is related to taht
[14:23:35] <PetefromTn_> LOL you must work pretty damn hard
[14:23:35] <_methods> oh a password
[14:23:46] <_methods> i guess i should have read back
[14:23:47] <_methods> lol
[14:40:58] <lair82> skunkworks I think we are all having that problem right now as hot as it is!! ;)
[14:42:05] <SpeedEvil> lair82: yeah. Today it got to 23C outside.
[14:42:08] <SpeedEvil> (Scotland)
[14:42:12] <SpeedEvil> damn hot
[14:44:18] <lair82> Today was only 82F, but sunday was 90F with a heat index of almost 98F, in Toledo Ohio
[14:44:28] <lair82> Wringing Wet sweating
[14:46:49] <Deejay> lol, "damn hot"
[14:49:40] <furrywolf> it's currently 66F / 19C here... too hot.
[14:51:13] <jdh> 97/118 heat index
[14:53:17] <furrywolf> I was somewhere last week that was 105F... fortunately I was only there for a couple hours, because I was utterly useless, pretty much unable to do anything but sit there drinking icewater... how the heck does anyone live where it gets that hot, much less function?
[14:53:29] <Deejay> hmm, you have a strange sense of warmth
[14:53:35] <jdh> indeed
[14:53:56] <jdh> I will wait a few hours befor I go biking
[14:55:26] <furrywolf> I live in an area where >70F is considered a heat wave.
[14:55:57] * Deejay freezes below 70F
[14:56:26] <furrywolf> I had the a/c on in my van today. because it was way too hot.
[15:02:57] <SpeedEvil> I had my house mainly at 40F last winter
[15:03:19] <Deejay> try to close the door next time ;)
[15:03:51] <SpeedEvil> I was heating only one room.
[15:05:30] <Tom_itx> 79°F cool front passing thru
[15:05:36] <Tom_itx> with showers
[15:11:27] <Loetmichel> *GNHA* wife made chicken legs in the oven... and forgot them... "follow the smoke and deactivate the smokedetectors" ... i couldn run fast enough to get to the second after the first one had triggered... $me opens all doors an watches the detectosr blink down... 3 leds.... 2 leds.... 1led... stays there for a while ;)
[15:11:44] <Loetmichel> at least now io know: all 5 detectors work ;)
[15:13:50] <XXCoder> lol
[15:13:52] <Loetmichel> ... LOUD that ;)
[16:11:50] <furrywolf> Loetmichel: they're not smoke detectors... they're timers! when they beep, the food is done. :)
[16:11:58] <XXCoder> lol
[16:12:56] <Loetmichel> furrywolf: you mean: done for... whats left ion the oven is pure carbon... its clean as after a pyrolyse cycle ;-)
[16:13:58] <furrywolf> lol
[16:14:10] <furrywolf> if that's the case, you need better smoke detectors!
[16:14:14] <XXCoder> compact it and you get nice diamonds
[16:14:26] <XXCoder> might need to hire superman though
[16:17:37] <Loetmichel> furrywolf: the detectors started secods after wife opened the kitchen door
[16:18:01] <Loetmichel> landlord did NOT install a detector in the kitchen... he knows why ;)
[16:18:51] <XXCoder> lol
[16:18:58] <furrywolf> lol
[16:20:17] <furrywolf> grrrr. UPS forgot my package at a location. AGAIN.
[16:20:36] <zeeshan> doh
[16:20:45] <zeeshan> fuck you sump pump!!
[16:21:09] <PetefromTn_> furrywolf starting to wonder if you might have pissed off your UPS guy at some point hehe
[16:21:45] <furrywolf> PetefromTn_: seeing as the first time they lost this package was around 3000 miles away, that's unlikely.
[16:22:01] <PetefromTn_> just sayin' ;)
[16:35:26] <Tom_itx> http://media.graytvinc.com/images/235_flood.jpg
[16:35:31] <Tom_itx> wonder what Noah felt like
[16:35:58] <zeeshan> furrywolf: gimme a generator
[16:36:00] <zeeshan> i want portable powerrrrrrrrr
[16:36:15] <Tom_itx> zeeshan, gonna hook it to your bicycle and use pedal power?
[16:36:19] <zeeshan> haha
[16:36:19] <zeeshan> no
[16:36:22] <zeeshan> gasoline my friend
[16:36:23] <zeeshan> GASOLINE
[16:36:25] <zeeshan> HC
[16:36:30] <zeeshan> co2
[16:36:31] <zeeshan> yea!!
[16:36:36] * zeeshan is a little excited
[16:36:37] <Deejay> gn8
[16:36:44] <Tom_itx> gn9
[16:36:51] <cradek> go home, you're drunk
[16:36:59] <zeeshan> i love gasoline
[16:37:01] <zeeshan> long live gasoline
[16:37:05] <PetefromTn_> zeeshan is gets excited pretty easily it seems hehe
[16:37:05] <Tom_itx> zeeshan you been whiffin fumes again?
[16:37:05] <zeeshan> gasoline gives me 800whp
[16:37:07] <cradek> stop sniffing gasoline
[16:37:24] <Tom_itx> or you got a mouse in your pocket?
[16:37:26] <zeeshan> no i actually conquered a fear today
[16:37:34] <zeeshan> i was afraid of the sump area of the house
[16:37:47] <zeeshan> motor was huming cause its fried
[16:38:10] <zeeshan> the sump area isn't as scary as i thought it would be
[16:38:18] <zeeshan> its just a plastic tube thats about 3 feet dep
[16:38:26] <zeeshan> i thought it was like one of those 20 ft wells
[16:38:33] <Tom_itx> just like a trash bucket
[16:38:34] <zeeshan> where a witch would come out of
[16:38:36] <zeeshan> yes
[16:38:36] <Tom_itx> with a lid
[16:38:50] <PetefromTn_> WTF is a sump area of a house ?
[16:38:55] <Tom_itx> no just snakes
[16:39:01] <zeeshan> http://static.panoramio.com/photos/large/24854752.jpg
[16:39:04] <zeeshan> this is what i imagined it to be
[16:39:10] <zeeshan> that is some scary shit.
[16:39:12] <Tom_itx> PetefromTn_, i've got 2 sumps in my basement
[16:39:19] <Tom_itx> one for runoff and one for wastewater
[16:39:20] <zeeshan> PetefromTn_: water collets
[16:39:55] <PetefromTn_> I don't have a basement and none of the houses we had in florida did either so not really familiar I guess
[16:40:12] <Tom_itx> water table isn't suitable for it probably
[16:40:24] <zeeshan> PetefromTn_: mostr of florida is a swamp
[16:40:25] <zeeshan> :-)
[16:40:43] <PetefromTn_> not the parts I lived in heh
[16:40:59] <PetefromTn_> but yeah quite a bit of it is..
[16:43:31] <PetefromTn_> got a little engraving job to do here
[16:44:12] <PetefromTn_> and got another one from one of the guys who works for my customer possibly hehe he asked me about it when I was walking out to my van LOL
[16:44:28] <zeeshan> whatcha engraving
[16:45:01] <PetefromTn_> just a logo
[16:46:37] <Tom_itx> zeeshan, this is a well:
http://www.bigwell.org/
[16:47:59] <Tom_itx> the stairs and cover were rebuilt after the tornado that took out the whole town
[16:50:39] <PetefromTn_> Can't imagine why anyone would want to live in tornado alley really.. but hell I want to live in florida where they have hurricanes LOL
[16:51:44] <Tom_itx> https://en.wikipedia.org/wiki/Greensburg,_Kansas#/media/File:Greensburg_kansas_tornado.jpg
[16:52:22] <Tom_itx> may be the widest one on record, i'm not sure
[16:52:25] <Tom_itx> 1.7 mi wide
[16:53:07] <PetefromTn_> yeah that does not look like much fun... at least with hurricanes you can have a hurricane party ;)
[17:02:31] <Tom_itx> we've gotten about 2" of rain in the last couple hours
[17:03:26] <Tom_itx> nice 5 o'clock drive home :D
[17:04:49] <Loetmichel> Tom_itx: water table is no hindrance to a basement
[17:04:53] <Loetmichel> just makes it expensive
[17:05:33] <Tom_itx> that's why they don't do it in those places
[17:05:44] <Loetmichel> neighbor of my mothers new guy (they live in an area in germany which has the water table 30cm beneath the surface) has done it
[17:05:49] <PetefromTn_> sure makes diggin the hole a bitch LOL
[17:07:21] <Loetmichel> the diggers simply rammed some walls into the ground, got some big pumps, digged the hole for the basement, oured a "basement box" in one pour of conrete, put the cables and tubes in and sealed them, put the dirt back around the huse and then pulled the walls out ;)
[17:08:06] <Loetmichel> and THEN started bricklaying the first and second floor ;)
[17:08:11] <Loetmichel> and the roof
[17:08:48] <Loetmichel> ya know these steel wall segments that are like a trapezidoal wave?
[17:09:30] <Tom_itx> also used in bridge construction
[17:10:06] <Loetmichel> its really simple if you have the tech... or the money to rent it ;)
[17:10:50] <PetefromTn_> everything is simple with enough money and hydraulics :D
[17:10:54] <Loetmichel> and as basements in germany are made of concrete most of the time anyways it was just ramming the walls around the house and the pumps as a difference
[17:11:36] <Loetmichel> and the fact that they used "watertight" concrete and did it in one pour so no joints that can start to leak
[17:13:29] <Tom_itx> similar to pouring grain elevators or water tower bases.. all one pour
[17:15:03] <Loetmichel> i HAVE heard of some houses swimming away after a flood at some rivers
[17:15:09] <Loetmichel> but thats was YEARS ago
[17:15:23] <Loetmichel> i think they learned their lesson by now ;)
[17:15:52] <Loetmichel> you shouldnt think that 300 tons of concrete and stuff can swim...
[17:16:02] <Loetmichel> ... they can :-)
[17:16:06] <PetefromTn_> In Florida we had a customer we were working on their house and they had a big in ground pool
[17:16:19] <PetefromTn_> they had a bunch of flooding recently
[17:16:44] <PetefromTn_> and the pool overflowed a bit so they decided to drain it some to clean up after the storms
[17:17:03] <PetefromTn_> the entire pool lifted up out of the ground including the decking around it
[17:17:05] <Loetmichel> let me guess: the house has risen?
[17:17:23] <Loetmichel> ah, only the pool ;)
[17:17:24] <PetefromTn_> then the silt/dirt sort of fell back into the hole around the edges
[17:17:53] <Loetmichel> so they had to destroy the pool and poour a new one?
[17:17:54] <PetefromTn_> so the entire pool sat about eight inches higher and the entire deck around the pool was off the ground by that much
[17:18:21] <PetefromTn_> yup totally wasted the pool
[17:18:45] <PetefromTn_> they wound up crushing it with a piece of heavy equipment crushing in the walls and then filled it in with dirt
[17:18:52] <PetefromTn_> so no more pool in that yard
[17:18:58] <PetefromTn_> it was a NICE pool too...
[17:19:35] <PetefromTn_> it was remarkable to see such a large concrete pool basically floating on a pocket of water underneath it.
[17:19:51] <PetefromTn_> it was still almost half full inside it too...
[17:23:02] <Loetmichel> the dutch drive that to the top:

[17:32:12] <zeeshan> lair82: when you pulled the reader head out
[17:32:16] <zeeshan> did it need a lot of force to pull out?
[17:32:23] <zeeshan> i got the end caps off
[17:32:30] <zeeshan> but the reader head wont come off
[17:32:40] <zeeshan> im pulled with maybe 5lb force

[17:36:34] <DaViruz> those spindle bearings look mighty sturdy
[19:52:07] <furrywolf> http://lostcoastoutpost.com/2015/jul/21/video-video-salute-years-brave-quadiators/ just in case I needed a reminder that this area is full of rednecks, not hippies. :)
[19:56:30] <furrywolf> hrmm, that reminds me, I think the auto show and tractor pull is coming up soon... always a good swapmeet next to it.
[19:56:46] * SpeedEvil is reminded of people with four arms livving in space.
[19:57:30] <furrywolf> ?

[20:32:49] <Valen> what is the name for the coupling where you link a ballscrew to an axis but it doesn't couple things like the angle of the screw to the axis
[20:33:55] <PetefromTn_> you mean a lovejoy?
[20:34:21] <Valen> doesn't look like it
[20:34:29] <PetefromTn_> helical?
[20:34:33] <Valen> sorry I should say its how you attach the ball nut
[20:34:36] <cradek> I think in general they are called flex couplings
[20:34:45] <cradek> oh the nut? I don't know
[20:34:51] <PetefromTn_> ballnut mount?
[20:34:54] <PetefromTn_> flange mount
[20:35:07] <Valen> to the axis, but it only couples motion along the axis, any other errors of the screw aren't coupled into the axis
[20:35:30] <PetefromTn_> preloaded mount?
[20:35:50] <Valen> so the nut is free to wobble say on X and Y but it'll only move along Z
[20:36:02] <archivist> "any other errors of the screw aren't coupled into the axis" hardly possible
[20:36:27] <PetefromTn_> no idea what you are talking about man
[20:37:17] <furrywolf> sounds like some form of gimbal, but I've never seen such a device used for such a purpose.
[20:37:32] <furrywolf> the normal solution is to make sure your screws and your ways are parallel. :P
[20:37:46] <Valen> heh, always easy to say ;->
[20:38:19] <furrywolf> if it were a bearing, that would be self-aligning, but again, never seen it used for that...
[20:42:51] <archivist> even if the nut is allowed to move sideways to accommodate a bend in the screw that gives a larger distance error due to the arc from the controlled end of the screw
[20:43:28] <archivist> keeping the nut central reduces the error in that case
[20:51:53] <furrywolf> I still have a slight wobble in my X screw, but it's so slight it's taken up in the mount with no problems
[20:53:09] * SpeedEvil passes furrywolf a hammer.
[20:53:46] <SpeedEvil> you can often straighten shafts by stroking them in the right place
[20:54:15] <furrywolf> I spent a good bit of time with the oxytorch and a hammer to get it straight.
[20:54:26] <furrywolf> got it to within "good enough" inches. :)
[20:54:26] <PetefromTn_> SpeedEvil ROFL
[20:54:45] <SpeedEvil> I have wondered about rotary
[20:55:08] <SpeedEvil> - draw the shaft through while _just_ causing it to yield to reduce stress
[20:55:09] <furrywolf> http://fw.bushytails.net/bentleadscrew01.jpg started like that. got it within a few thousandths.
[20:55:43] <SpeedEvil> nice
[20:59:15] <Valen> wow
[20:59:27] <Valen> what happened to it?
[21:02:00] <furrywolf> Valen: machine got knocked over by a forklift
[21:02:19] <Valen> I bet that made an expensive sounding noise
[21:02:46] <archivist> look at vids on youtube for delicate straightening, use a press that has good control
[21:04:28] <furrywolf> Valen: dunno, it was two owners before I got it. heh.
[21:04:43] <furrywolf> archivist: I used a hammer. the most delicate tool ever made. :P
[21:05:02] <Valen> I guess you didn't have much to lose
[21:05:45] <PetefromTn_> should be able to pop it in a lathe and tweak it in pretty damn close....
[21:05:50] <archivist> furrywolf, I had fun with a customers clock dial, did not take pics though
[21:07:19] <furrywolf> I got it pretty damn close already. it works. it's all assembled and makes chips now.
[21:07:21] <archivist> http://www.repairengineering.com/shaft-straightening.html
[21:08:42] <furrywolf> this is no longer a current project.
[21:09:26] <archivist> not for you but I think valen needs to do something
[21:10:41] <Valen> I was just curious about it was all, I remember reading something about it on super duper precision mills
[21:15:42] * furrywolf would figure such mills use precision in their assembley, and wouldn't need such things
[21:29:28] <zeeshan> when a motor rotates back and forth
[21:29:30] <zeeshan> a tiny amount
[21:29:33] <zeeshan> this is called servo hunting right?
[21:29:45] <malcom2073> If said motor is a servo, sure
[21:29:57] <zeeshan> what causes it
[21:30:05] <malcom2073> badly tuned pid, I forget which part
[21:30:08] <zeeshan> looks like cleaning the glass scale helped
[21:30:17] <zeeshan> hmm badly tuned pid..
[21:30:21] <zeeshan> i tuned this so nice though!
[21:33:04] * zeeshan retunes the axis
[21:35:15] <Valen> you want to look at your deadband too
[21:35:44] <Valen> you can get stick/slip fun times if you have an integral term with no deadband
[21:37:11] <Valen> zeeshan ^
[21:39:53] <MacGyverX> Anyone familiar with the DDMMV2.1? And would it work with LinuxCNC?
[21:51:29] <zeeshan> there is no I.
[21:51:34] <zeeshan> just ff1 and P
[22:11:01] <zeeshan-mill> it wasnt the tune
[22:11:11] <zeeshan-mill> it was the offset pot on the servo drive
[22:12:38] <zeeshan-mill> hm
[22:12:44] <zeeshan-mill> nm its back =/
[22:14:11] <trentster> Howdy all, is it best practice to use thick plates for Z axis, specifically for the part the rails attach to? e.g. I understand for the gantry sides thicker and more rigid the better, but for Z plates does it make a difference using e.g. 10mm thick vs 15mm thick flat bar stock?
[22:14:20] <trentster> its is just going to make it heavier
[22:16:31] <zeeshan-mill> do the calculations?
[22:16:34] <Roguish> trentster: stiffness is key. if you are concerned about the weight, try tubing (square, rectangular, round......)
[22:16:55] <zeeshan-mill> its hard to help without seeing your design
[22:17:00] <zeeshan-mill> and knowing the geomtry
[22:17:02] <trentster> Roguish: I am not talking about the gantry side plates - right?
[22:17:12] <Roguish> or things like I-beams.
[22:17:35] <Roguish> trentster: I am talking about everything, everywhere.
[22:18:19] <trentster> http://monosnap.com/image/sLxh83DTAUADmKMt5FMAqp6RUEtRlX
[22:18:24] <Roguish> simple equation.......... deflection = force X stiffness
[22:18:36] <trentster> Roguish: this is what I currently have
http://monosnap.com/image/sLxh83DTAUADmKMt5FMAqp6RUEtRlX
[22:19:11] <trentster> I have just purchased these
http://monosnap.com/image/ZQqcMkz3YLA8MQHf3oSfNJpa3LF4xw to remake the z axis which means I will have to buy new aluminium stock.
[22:19:22] <trentster> what is currently there is 12mm and its pretty heavy
[22:19:29] <Roguish> r u talking about the vertical plates holding the cross-slide in the air?
[22:19:37] <zeeshan-mill> Roguish, thats doesnt work for beams
[22:21:26] <zeeshan-mill> http://i.imgur.com/ITkhiB8.png
[22:21:29] <zeeshan-mill> is this noise ?
[22:21:36] <zeeshan-mill> thats causing my servo to act funky
[22:21:48] <trentster> Roguish: I am talking about this
http://monosnap.com/image/mQrIfFcFMUzFH1yqIgFZWf1jnEXLT6
[22:22:59] <Roguish> ah, ok. that plate mounts to the bearing blocks, right? and is a mount for the spndle?
[22:23:22] <trentster> Roguish: yup exactly
[22:23:48] <Roguish> so, it could probably be lighter. maybe thinnner, and even carved away in the middle some.
[22:24:50] <Roguish> how many bearing blocks? 2 top and 2 bottom?
[22:25:19] <Roguish> like on the cross axis?
[22:26:17] <trentster> yeah 2top and 2 bottom
[22:26:39] <trentster> will be using those SCHNEEBERGER's in the photo above
[22:26:54] <trentster> which should be a ton stiffer and better than supported chinese rail I have there.
[22:27:57] <Roguish> schneenberger are good, no doubt, and $$$
[22:28:19] <Roguish> some even have built in linear scales.
[22:28:41] <trentster> yeah I had never heard of them before, but they look like good stuff.
[22:29:16] <trentster> yeah they have rails with encoder lines built into the rails and intelligence in the blocks
[22:29:21] <MacGyverX> Anyone familiar with the DDMMV2?
[22:29:33] <trentster> but that is for cpu fabrication really for nano scale accuracy
[22:34:13] <pcw_home> zeeshan-mill: looks like normal encoder dithering, what is your scale resolution? ( and units? )
[22:34:24] <CaptHindsight> MacGyverX:

[22:36:42] <zeeshan-mill> pcw_home, hmm
[22:36:56] <CaptHindsight> MacGyverX: the USB portion won't without some work and not in real time
[22:36:58] <MacGyverX> yup
[22:37:24] <zeeshan-mill> encoder_scale is set to 25400
[22:37:33] <MacGyverX> Okay.
[22:37:34] <CaptHindsight> looks like nobody has tried it, there are LPT breakout boards for less than half that price
[22:37:34] <trentster> Roguish: you said carved away in the middle somewhat? really? I have never seen anyone do that for Zaxis plates
[22:37:47] <zeeshan-mill> machine units are set to inches
[22:37:49] <MacGyverX> I got mine for 20 bucks.
[22:37:57] <MacGyverX> :/
[22:38:04] <zeeshan-mill> pcw_home, only Y axis does this
[22:40:25] <pcw_home> at 25400 counts/inch you might expect 40 or 80 uinch dither but thats 400 uinch
[22:41:11] <zeeshan-mill> yes
[22:41:13] <pcw_home> Possibly bad /dirty encoder or EXE box?
[22:41:23] <zeeshan-mill> i cleaned up the encoder scale
[22:41:25] <zeeshan-mill> its not losing position now
[22:41:29] <zeeshan-mill> which is good!
[22:41:52] <zeeshan-mill> im using the idp101 boards
[22:43:13] <pcw_home> try running halscope at 5 ms/div and looking at the edges
[22:43:57] <pcw_home> looks to me like interpolation is not working well
[22:45:18] <Valen> trentster: if you want to make it stiffer put some bits sticking "out" from the plate if you will
[22:46:24] <zeeshan-mill> looks like square waves for analogout1
[22:46:32] <trentster> Valen: bit sticking out from the plate - like 1/4 endmills :P
[22:46:48] <zeeshan-mill> let me look at encoder counts
[22:47:49] <zeeshan-mill> jumps between
[22:48:01] <zeeshan-mill> 14777 and 14786
[22:51:30] <valen00> Doh blackout :-(
[22:51:51] <valen00> As I was saying make a C section or box it in
[22:52:02] <pcw_home> are there anything like sine/cosine gain pots on the read head?
[22:52:11] <valen00> Do you have the stiffness spec on those rails?
[22:53:49] <valen00> Also just as a sanity check what sort of cutting force should I be using for my calculations for a finish pass with a 6mm cutter in steel? Just a ballpark to see if I'm somewhere close
[22:53:52] <zeeshan-mill> no pcw
[23:04:08] <zeeshan-mill> ugh its losing position again
[23:05:29] <zeeshan-mill> wtf!!
[23:44:18] <CaptHindsight> does it only lose position in that one area of the scale or over random areas of the scale?
[23:44:32] <CaptHindsight> zeeshan-mill: ^^
[23:45:38] <zeeshan-mill> if i jog every 50 thou
[23:45:52] <zeeshan-mill> it ownt lose position at 0, but loses at 50
[23:45:58] <zeeshan-mill> then will be okay at 100, but loses at 150
[23:45:59] <zeeshan-mill> etc
[23:46:11] <zeeshan-mill> i think that is just a fluke that its happening like that
[23:48:52] <CaptHindsight> scratched or damaged scales will of course have odd behaviors when passing over the bad spots
[23:49:47] <zeeshan-mill> i guess only way to fid out
[23:49:49] <zeeshan-mill> is put an scope on it?
[23:50:06] <CaptHindsight> if it happens randomly over previously good areas then I might expect the read head or the circuits after that
[23:51:04] <CaptHindsight> might be a good start
[23:51:12] <CaptHindsight> bbl...zzzzzzzz
