[00:03:38] <Crom> ftp server on my phone works pretty good... getting upwards of 1200kBS
[00:03:52] <Crom> low around 500kBS
[00:53:09] <evil_ren> hey guys, what do you know about: plastic injection molding
[00:53:13] <evil_ren> ?!
[00:53:42] <evil_ren> say i got a part, its profile is kind of like a hat
[00:53:59] <evil_ren> or like a rounded box with a lower hotdog
[00:54:43] <evil_ren> and three sides have ~2 degree draft, but one side is vert
[00:54:51] <evil_ren> WILL IT BLEND!?
[00:55:05] <evil_ren> i think it will probably blend
[00:55:47] <evil_ren> i mean like, willit be successful, not like, will it mix with something that i have not yet mentioned
[03:25:16] <Deejay> moin
[04:38:06] <XXCoder> _methods: lol havent thought of heavens gate for years now
[04:38:43] <XXCoder> wonder where the leader - one who chickened out, went.
[07:34:04] <pink_vampire> I just woke up now and it's 8 AM there is daylight outside O_o
[07:35:03] <pink_vampire> I'm not a vampire anymore :(
[07:39:01] <witnit> just be glad you dont have jury duty in 15 minutes
[07:41:10] <_methods> just say 2 words
[07:41:19] <_methods> and you'll be out of jury duty
[07:41:25] <_methods> jury nullification
[07:42:07] <Deejay> hi pink, mojn witnit, hi methods
[07:42:11] <_methods> they'll never call you again lol
[07:42:13] <_methods> hola
[07:48:40] <pink_vampire> my panel is ready for basic wiring, to be able to power the machine to make more parts for the panel.
[08:12:27] <Simonious> so.. for linux CNC what are people using to drive bots in terms of ports - parallel port only?
[08:12:35] <Simonious> (that is all I've used thus far).
[08:19:12] <OdinYggd> I doubt it would be so limited
[08:19:25] <OdinYggd> I've heard people in here talking about various driver modules with USB and network connectivity
[08:19:50] <OdinYggd> Though the CNCs I'm worknig with are all mass produced units, they don't have linuxCNC on them. (yet. I might get a chance to retrofit one)
[08:20:20] <OdinYggd> actually now that I think about it, it would be really interesting if LinuxCNC supported the servocard in the Prototrak M2. Would be a drop-in upgrade to give them new features
[08:20:25] <OdinYggd> I should try that sometime
[08:20:41] * Simonious ponders
[08:20:47] <Simonious> USB is fully real time?
[08:24:11] <OdinYggd> Nope.
[08:24:27] <OdinYggd> But it is close enough that you can work with it.
[08:24:31] <Simonious> so.. that doesn't seem like the way to go..
[08:24:39] <OdinYggd> USB requires a fair bit of logic on the other end to decode it anyway
[08:24:57] <OdinYggd> So if you use USB to relay packets full of position commands, and the realtime operations are done in hardware at the endpoint instead of the PC
[08:25:04] <Simonious> I suppose I could put a smoothieboard in between the PC and the Router, but.. then I don't need linuxCNC or the PC really
[08:25:04] <OdinYggd> you enter a situation where a USB connected CNC works just fine
[08:25:52] <Simonious> yeah.. I think that is a different scenario than I was thinking - I was thinking gecko drivers and endstops and PC..
[08:25:57] <OdinYggd> It moves the loop-closing from the PC out to a controller card, which is given a position and feedrate then moves there and holds by itself
[08:26:21] <Simonious> right, but if I've got a controller card I hardly need the PC and linuxCNC - re smoothieboard
[08:36:55] <_methods> i don't think you'll find many people in here recommending USB
[08:37:21] <archivist> OdinYggd, usb is useless
[08:37:27] <_methods> ^^
[08:38:07] <archivist> with linuxcnc only used for jog wheels usually
[08:38:24] <_methods> i just use a cheap usb numpad
[08:41:33] <skunkworks> OdinYggd: that is a mach3/4 or any other buffered system model. Linuxcnc uses realtime in the compter to do the motion so there needs to be a realtime connection to the hardware. No one has gotten usb working with low enough latency to work with linuxcnc.
[08:42:23] <skunkworks> currently spi, ethernet, pci, pci-e and such work well with linuxcnc
[08:44:08] <Simonious> skunkworks: and of course parallel - what interface do you use?
[08:44:15] <Simonious> /prefer?
[08:44:51] <skunkworks> I have used pci, ethernet and parallel.
[08:45:44] <Simonious> what do pci and ethernet interfaces look like?
[08:46:44] <skunkworks> http://store.mesanet.com/index.php?route=product/product&product_id=55&search=5i25
[08:47:06] <skunkworks> http://store.mesanet.com/index.php?route=product/product&product_id=302&search=7i92
[08:47:46] <skunkworks> couple examples. moves the stuff that the computer doesn't do well to the hardware (high speed stepgen, pwmgen, encoder counting and such)
[08:48:51] <Simonious> ha.. oh those are just parallel ports
[08:49:03] <skunkworks> no..
[08:49:08] <skunkworks> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?LinuxCNC_Supported_Hardware
[08:50:36] <skunkworks> Simonious: it sort of emulates a printer port out of the box - but with mhz stepgens and such. but you can expand it with things like http://store.mesanet.com/index.php?route=product/product&product_id=120&search=7i77
[08:51:07] <skunkworks> or http://store.mesanet.com/index.php?route=product/product&product_id=119&search=7i76
[08:52:31] <Simonious> cool, thanks for the info :)
[09:10:56] <MrSunshine> set screws .. can you trust them not to twist ?
[09:11:09] <MrSunshine> damn ... thats what i was supposed to do ... make a flat on the bar :P
[09:14:29] <archivist> or a dimple
[09:14:44] <archivist> an no you cannot trust them
[09:15:22] <_methods> devious set screws
[09:16:45] <gregcnc> green loctite will fix that
[09:17:34] <MrSunshine> i dont realy want to loctite it to the axle tho =)
[09:18:33] <gregcnc> next guy's problem....unless you're the next guy
[09:18:40] <archivist> I prefer some form of clamping
[09:18:46] <MrSunshine> i was thinking of splitting the part that has no kogs to make it clamp on the axle
[09:19:44] <MrSunshine> as there isnt very much thrust going on but its not allowed to move .. and like usual there is always a run in phase =)
[09:24:57] <MrSunshine> hmm need a pin vice .. :/
[09:25:29] <_methods> i just got a nice starret one for xmas
[09:25:44] <_methods> handy little buggers
[09:26:13] <MrSunshine> yeah looks like it =) need to grind down some set screws =)
[09:26:17] <_methods> i think i'm going to ask santa for a nice jewelers vise for xmas this year
[09:29:09] <_methods> http://www.amazon.com/Jeweler-Attachments-Engraving-Setting-Jewelry/dp/B00BR4XWRG
[09:29:55] <_methods> maybe i'll just make one
[09:30:00] <_methods> that will be more fun
[09:33:56] <_methods> http://myweb.tiscali.co.uk/remark/pages/hobbies/evice.html
[09:34:03] <_methods> that one turned out nice
[09:34:44] <gregcnc> ...that's what it's called engraving vise
[09:36:32] <_methods> yeah
[09:36:48] <_methods> engraving vise i think some people call them jewlers vises or ring vises
[09:37:10] <gregcnc> those look handy, but I can't think of what I'd use it for.
[09:37:25] <_methods> sometimes i have to file little stuff
[09:37:32] <_methods> or hold some small things
[09:37:34] <_methods> hehe
[09:37:54] <_methods> probably not much use for anything but little desk type handwork
[09:38:15] <_methods> unless you make the big bowling ball ones
[09:39:05] <_methods> http://i44.photobucket.com/albums/f24/hephaestus61/Ashokan%202008/Andy-Porter-engraving.jpg
[09:53:36] * Loetmichel2 is riding the edge again. alredy ripped off the second mill bit... if you forget to cool the AlMg3 with plenty of alcohol every now and then it will break the milling bit soon enough. -> https://www.youtube.com/watch?v=CqXauMOhWos
[09:58:30] <FinboySlick> _methods: So gravity is all that holds the vice?
[09:58:35] <FinboySlick> vise
[09:58:44] <_methods> yeah on some
[09:58:47] <FinboySlick> Obviously, gravity holds every vice.
[09:59:03] <_methods> some have a clamp system on the ball
[09:59:27] <FinboySlick> Pretty fancy.
[10:02:44] <_methods> i saw one guy made a weld table out of a bowling ball like that
[10:03:04] <_methods> https://www.youtube.com/watch?v=uwv_XjWp1KA
[10:04:12] <Loetmichel2> nice idea
[10:04:25] <FinboySlick> Heh, are those brake disks?
[10:06:48] <_methods> yeah old rotors
[10:08:01] <_methods> i wonder if the bowling alley will just give away their bad bowling balls
[10:08:12] <_methods> i guess i'll have to hit some yard sales lol
[10:08:51] <FinboySlick> I can only imagine lots of old widows eager to get rid of 'em.
[10:09:23] <_methods> yeah
[10:09:34] <FinboySlick> And now I'm thinking of the movie 'Kingpin'.
[10:11:25] <FinboySlick> Ah Farelly brothers, go back to doing awesome movies.
[10:16:00] <CaptHindsight> how come I never have parts to weld that small that would fit on that table?
[10:23:28] <_methods> hehe
[10:23:52] <_methods> i suppose you could make a giant one with one of those exercise balls
[10:23:59] <_methods> just fill it with epoxy
[10:24:13] <_methods> then make GIANT weld positioner table
[10:26:11] <JT-Shop> _methods: were you the one trying to weld 0.020" ss?
[10:30:39] <CaptHindsight> how about a regular old flat welding table on the floor and then suspend myself from a wire and boom?
[10:32:12] <gregcnc> something more like this https://www.youtube.com/watch?v=CoA-m5iHG9s
[10:34:14] <_methods> JT-Shop: yeah i got it
[10:34:30] <_methods> pete has the same machine as me and he gave me some pointers
[10:34:34] <_methods> works great now
[10:34:41] <_methods> besides the operator part of the equation
[10:36:10] <_methods> https://www.dropbox.com/s/9ilmbxkf0846ir0/2016-03-14%2017.23.42.jpg?dl=0
[10:36:23] <_methods> https://www.dropbox.com/s/dzgwqsvpmj9m0xu/2016-03-14%2017.22.38.jpg?dl=0
[10:37:00] <JT-Shop> cool
[10:37:09] <_methods> the machine does a great job..... me not so much
[10:37:10] <_methods> lol
[10:37:42] <JT-Shop> I just found a chart that relates angle to depth of penetration of the weld
[10:37:51] <_methods> ah
[10:38:11] <_methods> i'm luckin out
[10:38:12] <JT-Shop> http://s94.photobucket.com/user/weldphoto/media/GTAElectrodeAngle.jpg.html
[10:38:19] <_methods> laser is cutting some 22ga stainless today
[10:38:27] <JT-Shop> https://www.millerwelds.com/resources/article-library/tips-to-improve-tig-arc-starts-and-promote-arc-performance-in-aerospace-and-other-low-amp-applications
[10:38:37] <_methods> so i'm going to have him cut me some parts so i don't have to do it with tin snips at teh house lol
[10:38:46] <_methods> ah thx for the links
[10:38:51] <_methods> i'll check them out
[10:39:08] <_methods> that was with a dirty tungsten too
[10:39:17] <_methods> i ground a new one and the welds came out WAY better
[10:39:47] <_methods> probably cleaning the material would help too
[10:40:34] <CaptHindsight> gregcnc: nope, I make robots and I'd never get in one
[10:41:39] <FinboySlick> Meatbags are fragile.
[10:41:55] <FinboySlick> As AvE says: You're the softest thing in the shop.
[10:42:09] <tiwake> gregcnc: his head came really close to hitting that concrete floor...
[10:42:41] <CaptHindsight> that why we need a good GUI for working at the beach where its safe
[10:54:02] <Loetmichel2> FinboySlick: i beg to differ
[10:55:14] <Loetmichel2> meatbags may not be as hard as steel, but they can take abuse WAY better than any machine. they even recover from 500% overload short enough exposure. Machines are brohen once overloaded ;)
[10:57:39] <gregcnc> well you could program the arm to do the welding, but then you just get to watch
[11:00:11] <tiwake> Loetmichel2: self-repairing goes a long ways
[11:24:47] <R2E4> JT-Shop, Do you have 7i92's in stock?
[11:37:46] <JT-Shop> R2E4: yes
[11:42:19] <JT-Shop> http://mesaus.com/index.php?route=product/product&path=66&product_id=63
[11:51:42] <jdh> nifty
[11:52:25] <jdh> won't let me add to cart. says firmware option required
[12:05:13] <Loetmichel2> FinboySlick: or as friends say: the only thing harder in my workshop than my carbide tools are my balls... ;) -> http://www.cyrom.org/palbum/main.php?g2_itemId=12244&g2_imageViewsIndex=1 ;-)
[12:07:36] <lair82> Good Afternoon guys, I have been watching the machine that is suspected of memory leaks, that is using gmoccapy, and the memory hasn't gone over 6% watching it with "top", but the CPU has gradually gone up to right now, 71%. It was at roughly 20% when we restarted the control, and I started watching this. Any thoughts?
[12:08:27] <Sync_> well, what is using the cpu?
[12:08:50] <CaptHindsight> I guess they are still fixing the memory leak
[12:08:57] <CaptHindsight> there was some recent patch
[12:09:14] <CaptHindsight> check the ML and the forums
[12:11:12] <lair82> Here is a screen shot, https://app.box.com/s/g297dsqy5128ucxcxs5lcsmha8lvzl48
[12:12:49] <CaptHindsight> not sucking memory, but cpu cycles
[12:13:52] <Sync_> well, I guess you have to ask norbert
[12:14:11] <lair82> The only mem leak fix I see was on that xhc-hb04 pendant
[12:15:40] <CaptHindsight> what's gmoccapy doing? rendering moving graphics? Just sitting there idling as far as you know?
[12:16:43] <pcw_home> its idling with the gas and brakes on
[12:17:15] <Sync_> well, that's the way to do it to get the brakes nice and hot
[12:18:21] <CaptHindsight> lair82: what's happening?
[12:19:03] <CaptHindsight> how long is gradual? 1 minute, 1 hour? ??
[12:19:03] <lair82> The machine is making chips right now, and has been every day, 10hrs a day since thursday afternoon when it was last re-started
[12:19:32] <lair82> gradual what?
[12:19:45] <CaptHindsight> can you give us more info?
[12:20:02] <CaptHindsight> " but the CPU has gradually gone up to right now, 71%"
[12:20:39] <lair82> The gui just slowly starts lagging in regards to screen refresh, and commands with the touch screen actually happening
[12:21:46] <lair82> once it starts lagging, it gradually gets worse and worse until it is pretty much froze up, and we have to hard reset the PC, then restart everything
[12:22:21] <CaptHindsight> is this the only machine with this config of gmoccapy that you have?
[12:22:21] <pcw_home> not that its a real fix but you did have one core turned off in the BIOS
[12:22:23] <pcw_home> re-enabling this will help speed wise (for a while anyway)
[12:23:21] <CaptHindsight> why is one core turned off?
[12:23:28] <lair82> When I reset it last thursday afternoon, according to "top" it was around 20% CPU, and 2.5% memory, yesterday it was roughly 55% cpu, and 5.8% memory
[12:23:54] <lair82> and today it is what the screen grab shows
[12:25:17] <lair82> Again me not knowing near what you guys know, I was under the impression that it was best to "isolcpus=1" so in the bios, I set it to 1 cpu
[12:26:06] <lair82> I'm going to ask the operator if he is noticing anything with the control hanging up, BRB
[12:26:46] <CaptHindsight> isolcpus=1 is a kernel option, it doesn't turn off any cpu cores
[12:27:16] <CaptHindsight> it isolates the real time applications to run on only one core
[12:27:58] <CaptHindsight> your BIOS might have an option to turn cpu cores ON/OFF individually, this is not the same thing as "isolcpus=1"
[12:28:28] <lair82> Oh, well that goes to show where I'm at with it. I was setting it in the bios, so it doesn't have a choice in that matter I guess.
[12:29:02] <FloppyDisk5_25> lair82 - Sorry to bother you, what command did you get to get the listing of %CPU, Mem, etc? Thanks.
[12:29:12] <lair82> top
[12:29:25] <pcw_home> In my experience isolcpus is bad for Preempt-RT network latency you want all the horsepower you've got
[12:29:55] <CaptHindsight> FloppyDisk5_25: http://linux.die.net/man/1/top
[12:30:17] <FloppyDisk5_25> Thanks!
[12:31:07] <CaptHindsight> lair82: are you running a RTAI or preempt-rt kernel?
[12:31:24] <pcw_home> On RTAI parallel port systems isolcpus may make sense, but not on Preempt-RT
[12:31:28] <lair82> I believe that is in effect on that machine, as goes for the other 2 turning centers as well. All 3 Turning centers have pretty much carbon copy builds; hardware, gui, options etc, but the other machines don't run half as much as this machine does, it runs 10hrs a day, 6 days a week
[12:31:55] <CaptHindsight> lair82: turn all the cores on in the BIOS settings
[12:32:03] <lair82> RTAI, this is still ubuntu 10.04 running a 5i23
[12:32:43] <lair82> The operator said he hasn't noticed anything yet
[12:35:05] <pcw_home> unless you are running a parallel port system I would not use isolcpus or disable any cores, it just makes everything slower
[12:35:16] <CaptHindsight> restarting every day might be the temporary fix
[12:36:31] <CaptHindsight> RTAI <2013 was pretty broken
[12:37:21] <CaptHindsight> from 2013-2015 RTAI got fixed but those fixes were never used by the Linuxcnc devs
[12:39:11] <CaptHindsight> 10.04 had all sorts of RTAI quirks, isolcpus did not behave as one would expect
[12:41:56] <CaptHindsight> well Dec 2015 RTAI 5.0 was merged in from the News on the from web page http://linuxcnc.org/
[12:43:08] <Loetmichel2> sooo, work done for today. finally got 5 side panels and half a bottom panel... (made a 3 side panels for the scrap heap, drills positioned wrong.) Tomorrow i will mahe the other three bottom/top panel halves and then fit that to the 19"2U server inside. if it fits i will make two RF-tight enclosures more ;) -> http://www.cyrom.org/palbum/main.php?g2_itemId=16182&g2_imageViewsIndex=1
[12:43:25] <JT-Shop> jdh: fixed it
[12:44:26] <FinboySlick> Loetmichel2: Good thing this isn't the 80s. Sparks might have triggered a hairspray fire! Just like Michael Jackson.
[12:44:58] <CaptHindsight> lair82: you could try the latest Linuxcnc and see if it is any better for your situation
[12:45:52] <CaptHindsight> lair82: install on a new drive so you can easily revert back to whats working for you now
[12:49:27] <CaptHindsight> lair82: you problem might have been fixed, maybe not but it's the quickest way to find out
[12:50:13] <lair82> OK, I was wondering about that, about building a new drive
[12:50:15] <CaptHindsight> lair82: but either way, turn all your cores on in the BIOS settings
[12:50:32] <lair82> The latest is wheezy though right?
[12:50:56] <CaptHindsight> yeah, how long will it take?
[12:51:08] <lair82> Uggh,
[12:51:20] <lair82> Umm, probably a few hours,
[12:51:31] <CaptHindsight> new GUI? don't want?
[12:51:57] <lair82> Have to go copy off the files out of the machine so I have current ones
[12:52:09] <CaptHindsight> yeah all the configs
[12:52:17] <lair82> I just don't like wheezy,
[12:52:30] <Loetmichel2> FinboySlick: they triggered an alcohol fire
[12:52:50] <lair82> I have a hard time on our mill that is running wheezy getting things going
[12:53:04] <Loetmichel2> ... forgot that i just wiked the metal sheet with an IPA-soaked rug and throwed said rug in the trascan... underneath the workbench
[12:53:29] <Loetmichel2> :-)
[12:53:54] <FinboySlick> Loetmichel2: See, if you had been Swedish, 100% the alcohol would have naturally found its way into your body.
[12:54:27] <lair82> I am still stumbling on getting sbackup installed and working properly to backup to my pc in the office, on the ubuntu machines, it took longer to download and install than it did to configure it and have it running.
[12:54:32] <CaptHindsight> yeah solvents need their own metal trash can with a lid marked "will kill you if handled wrong"
[12:55:04] <JT-Shop> R2E4: fixed the web site
[13:00:30] <CaptHindsight> it gets difficult when your work space has things that make fire, sparks, heat and you have materials that like to burn and explode, it gets tougher when you also need environmental control, a clean room and have bio-hazards
[13:03:34] <Loetmichel2> FinboySlick: i doubt it. it was 100% Isopropanol
[13:03:37] <Loetmichel2> not ethanol
[13:06:51] <lair82> now the cpu is running between 74 and 76%
[13:07:33] <lair82> xorg is at 20% cpu and 1.1% memory
[13:14:09] <pcw_home> apparently some people do drink Isopropanol
[13:17:47] <CaptHindsight> the blind and the dead
[13:18:18] <pcw_home> http://www.nejm.org/doi/full/10.1056/NEJMc063237
[13:19:08] <lair82> I thought that was what you drank when you were REALLY looking for a good time!!!!!!
[13:19:41] <CaptHindsight> Overdoses may cause a fruity odor on the breath as a result of its metabolism to acetone, which is further metabolized to produce the nutrients acetate and glucose.
[13:21:36] <OdinYggd> People following some fad diets also get into ketosis though and have that same fruity bad breath
[13:21:53] <OdinYggd> If you smell someone in that state insist that they have a 20 ounce of gatorade at least
[13:22:04] <OdinYggd> The hydration and electrolytes will help stop the zombification
[13:22:07] <maxcnc> hi from a wet day here in germany
[13:22:26] <OdinYggd> hello to you from a soggy wet day in New York
[13:22:37] <OdinYggd> Typical new england weather here
[13:22:44] <maxcnc> New yourk city or state
[13:23:10] <OdinYggd> NYS
[13:23:18] <OdinYggd> wow, someone finally realizes that NY isn't one big city

[13:27:19] <OdinYggd> Once you go beyond the city limits, it is complete wilderness
[13:27:25] <OdinYggd> Well, their wilderness is no match for mine.
[13:28:25] <maxcnc> MrSunshine: you shouud open a makerbot school shop
[13:28:27] <MrSunshine> (right now its stuckw ith some clamps just to test it out =)
[13:28:35] <MrSunshine> maxcnc: ? =)
[13:28:48] <maxcnc> as many people follow you
[13:29:15] <MrSunshine> not realy ? =)
[13:29:41] <maxcnc> many people became a good biseness owner as with a 3D printer and experiences in sculpting / construction parts
[13:29:58] <maxcnc> on the whole world
[13:30:51] <maxcnc> here in town someone started with one printer now there are 110 running in the shop no more space
[13:31:15] <maxcnc> if you go in the room its realy hot inside even with aircondicion
[13:31:57] <andypugh> Whenever I get an email that I have a new follower on YouTube I get a worried feeling about just how many wierdos there must be in the world.
[13:31:59] <maxcnc> and i got "Schwindelig" as all moving in other direction no fix point to star at
[13:32:28] <maxcnc> schaking
[13:32:28] <maxcnc> its the hell of noice also
[13:33:07] <CaptHindsight> OdinYggd: have any suggestions for garlic or onion breath? Isopropyl rinse or tic tac?
[13:33:23] <maxcnc> therfor im got strictly order from my boss to not upload any vids to youtube
[13:33:41] <maxcnc> he got 10k and more mails a week
[13:34:12] <maxcnc> and closed down the youtube channel at more then 1million hits
[13:34:30] <maxcnc> 3years ago now
[13:35:31] <Loetmichel2> maxcnc: motion sick
[13:35:31] <maxcnc> and still mails in for XYUVB foam
[13:35:49] <andypugh> A million hits could have brought in $800
[13:36:13] <maxcnc> and as Dan heeks closed down his post support the hell broke out on the closed mail system as all are in trash piled
[13:36:35] <MrSunshine> maxcnc: i have a small buisiness with the machine already .. tho its been down a while due to screw change, stiffening, redesign and depression :P
[13:36:54] <maxcnc> andypugh: 2parts a day bring more with less stress
[13:37:57] <maxcnc> you might see a rivival of him after his projekt closes thrue to money leek
[13:38:06] <tiwake> resume is almost done
[13:38:15] <tiwake> its looking pretty shiny
[13:39:05] <maxcnc> shop change is acording to plan at 15th Augest
[13:39:07] <CaptHindsight> tiwake: any further results with the anodize dyes?
[13:39:58] <tiwake> CaptHindsight: the not very dark (thinned out a lot) seems to come out kinda marbley
[13:40:28] <tiwake> donno why... maybe because I rinse them off after dying?
[13:40:38] <tiwake> with distilled water
[13:40:51] <tiwake> maybe something else should be used
[13:41:24] <CaptHindsight> you rinse them off with DI water after using the solvent dye?
[13:41:37] <tiwake> thats what I did, yeah
[13:41:40] <tiwake> heh
[13:41:42] <CaptHindsight> no need
[13:41:57] <tiwake> just drop in the sealer process?
[13:42:18] <CaptHindsight> let the dye dry, and then drop right into the sealer
[13:42:24] <tiwake> oh ok
[13:43:10] <tiwake> CaptHindsight: well, I'm not going to be anodizing anymore I don't think
[13:43:17] <tiwake> well, until I move to texas
[13:43:25] <tiwake> whenever that might be
[13:43:38] <CaptHindsight> the only solids in the dye is the colorant itself, the rest is just vehicle that evaporates
[13:43:58] <tiwake> yeah
[13:44:09] <CaptHindsight> keep the containers well sealed
[13:44:31] <tiwake> CaptHindsight: its not my problem anymore, selling it to the other guy
[13:44:41] <tiwake> :P
[13:44:45] <CaptHindsight> or worst case you'll open them with colored powder being the only thing you'll find
[13:45:26] <CaptHindsight> tiwake: what part of Texas?
[13:45:33] <tiwake> no idea
[13:45:54] <tiwake> I'm going to take my time to find something that fits me well
[13:46:16] <tiwake> my temp job local to me starts on the 28th
[13:47:54] <tiwake> CaptHindsight: its not really complete yet, but most (all?) of the content is there... http://tiwake.com/Walter%20Neary%20resume%202016.pdf
[13:49:35] <tiwake> inb4 I get email spammage from everyone in #linuxCNC "lul I have your email kbi"
[13:51:00] <maxcnc> tiwake: temp job local as toolmaker master chief CNC
[13:51:24] <tiwake> maxcnc: no, as an oil changer for the local ford dealer :-/
[13:51:29] <tiwake> lol
[13:51:51] <maxcnc> you shoudt do somthing on CNC NC control
[13:52:01] <maxcnc> as you are near Pro
[13:52:26] <maxcnc> texas is a New Green State there are lots of jobs on Steel
[13:53:21] <tiwake> maxcnc: thats not too far off... before I even thought about machining, I taught myself how to program in C and Java
[13:53:26] <maxcnc> Solar panel control Servo system programmer
[13:53:33] <CaptHindsight> _methods: 5 minute version https://www.youtube.com/watch?v=y4We5q8aTWQ
[13:53:42] <tiwake> made some interesting CNC machine programs... heh
[13:54:18] <maxcnc> Plasma cutter is best for texas as all Houses got there own singnes
[13:56:57] <tiwake> maxcnc: ideally I'd be looking for something where I get to work closely with engineers, on problem solving stuff before its actually a problem
[13:57:36] <maxcnc> insiders jobs are rear
[13:58:39] <tiwake> rare?
[14:00:11] <maxcnc> this groops of workers are closed and only realy long wmployes will choin
[14:00:45] <tiwake> *shrug*
[14:02:32] <maxcnc> hee in the South west of Germany so many people on CNC got missing and you can generate lots of money on little knolige
[14:10:26] <maxcnc> GN8
[14:11:29] <pink_vampire> https://www.youtube.com/watch?v=H-UjgSEmS0A
[14:14:58] <lair82> That was some serious engineering
[14:16:00] <pink_vampire> https://www.youtube.com/watch?v=GB2ZG0HWQ_8
[14:17:18] <pink_vampire> and he make it without cnc machine!
[14:18:21] <R2E4> JT-Shop, thanks will check
[14:24:47] <tiwake> PetefromTn_: check PM :P
[14:31:23] <_methods> PetefromTn_: ah you're here
[14:31:31] <_methods> thx for the help with the welder
[14:31:38] <_methods> got it working decent now
[14:41:28] <andypugh> I wonder where I can find a knob like this? http://littlemachineshop.com/products/Images/480/480.3742.jpg
[14:43:19] <_methods> what's the UK version of msc or grainger?
[14:43:52] <OdinYggd> andypugh, bijurdelimon
[14:44:04] <OdinYggd> Not sure if they have that layout, but they'd have that kind of oil pump at least
[14:44:21] <_methods> i think he just wants the handle
[14:44:25] <_methods> not the whole pump
[14:44:30] <andypugh> OdinYggd: I just want the knob :-) I am making my own oile built into the lathe apron.
[14:44:36] <OdinYggd> lol
[14:44:47] <OdinYggd> Dunno if Mcmaster doesn't have it.
[14:44:58] <OdinYggd> Most of the machines here to have had missing oil pump knobs I made new ones by hand
[14:45:06] <OdinYggd> Brass bar stock + a bit of boredom in the lathe
[14:45:21] <OdinYggd> By hand contouring with just a light touch of the screws and a good file to smooth the bumps
[14:46:16] <PetefromTn_> tiwake sorry man I have been outside in the shop prepping the machines for transport
[14:47:02] <lair82> you moving PetefromTn_?
[14:47:31] <PetefromTn_> yeah I am moving from East Tennessee to Florida
[14:47:42] <lair82> Thats a haul
[14:47:42] <andypugh> Yes, I suspect I will end up making one.
[14:48:15] <PetefromTn_> yeah the CNC's are all skidded up and strapped down ready to be loaded onto the guys trailer once he arrives
[14:48:20] <PetefromTn_> I expect him here soon
[14:48:44] <PetefromTn_> just found out they may be postponing the closing on my house a few days here
[14:49:04] <tiwake> shiny
[14:49:12] <tiwake> PetefromTn_: you have a job lined up?
[14:49:42] <PetefromTn_> well like I said before I work for myself largely but I have several different places I am going to be looking into when I get down there.
[14:50:36] <lair82> If you don't mind, why such a far move?
[14:50:56] <tiwake> how many miles are you moving?
[14:50:58] <PetefromTn_> because....FLORIDA :D
[14:50:58] <_methods> he's running from the police
[14:51:02] <tiwake> approximately?
[14:51:23] <PetefromTn_> no idea how many miles it is really but it is like a 13 hour drive
[14:51:25] <OdinYggd> I need to fix my resume pretty badly
[14:51:29] <OdinYggd> Its awful
[14:51:31] <tiwake> oh thats nothing
[14:51:34] <OdinYggd> and hasn't been updated in 7 years
[14:51:51] <jdh> he wants to get in one more florida vote for trump
[14:51:59] <_methods> hahaha
[14:52:00] <PetefromTn_> EXACTLY LOL
[14:52:07] <tiwake> I'm looking at moving a solid 24 hour drive away :P
[14:52:33] <PetefromTn_> tiwake what did you want me to look at there?
[14:52:42] <lair82> I'd stay in TN, Jack Daniels, Mmmmmmmmm, Yummy
[14:52:45] <tiwake> PetefromTn_: donno... sanity check?
[14:53:03] <PetefromTn_> It looks okay to me man but I am not an expert whatsoever on that LOL
[14:53:12] <tiwake> formatting tweaking
[14:53:17] <tiwake> no idea
[14:53:18] <tiwake> lol
[14:53:49] <PetefromTn_> does tiwake have some meaning?
[14:53:59] <tiwake> no
[14:54:16] <PetefromTn_> ok
[14:54:57] <tiwake> well, its kinda titanium wake scrunched down... from a computer game I played a tiny bit a long time ago
[14:55:11] <PetefromTn_> anyway I am gonna load up my Tig welder, my wood shaper, my horizontal bandsaw and whatever else I can stuff into my Astro van after we load up the machines and we are going to head out in the moring.... LOL
[14:55:18] <jdh> I worked for jack daniels a couple summers in school
[14:55:41] <_methods> damn good luck
[14:55:44] <_methods> i hate moving
[14:56:06] <jdh> pete: spring break for kids?
[14:56:10] <PetefromTn_> Oh man I hate moving too but this will probably be the last time
[14:56:42] <tiwake> until you get old and kids shovel you into a nursing home
[14:56:48] <_methods> damn 80/20 finally made a solidworks library
[14:56:49] <_methods> wtf
[14:59:00] <_methods> better late than never i guess lol
[15:13:53] <FloppyDisk5_25> _methods - got an email on that as well. I guess when you have enough business it's not a priority.
[15:14:34] <FloppyDisk5_25> I saw IPS (which is same as item) at least had sketches to use w/ SW's Weldments. Such a pain to make 8020 weldment pattern files.
[15:14:38] <FloppyDisk5_25> All that time, gone...
[15:17:15] <_methods> yeah
[15:17:30] <_methods> i never understood why they didn't have a library
[15:27:23] <witnit> hooray they didnt pick me for jury duty
[15:30:55] <Deejay> you can still do it as volunteer ;)
[15:32:59] <OdinYggd> Why are you cheering?
[15:33:06] <OdinYggd> You would have gotten paid to sit there and listen to other people's problems
[15:33:17] <OdinYggd> Then at least appear to make a fair recommendation based on them
[15:33:44] <witnit> Im not comfortable with judging a person without prior knowledge of their demeanor
[15:34:13] <OdinYggd> All they are asking for is given the presented facts do you think they did it and if they did what would you suggest be done about it
[15:34:27] <OdinYggd> It is still up to the judge to decide if they actually will be sentenced for it, and what that sentence will be
[15:34:39] <witnit> I dont agree with reasonable doubt conviction
[15:34:44] <OdinYggd> They don't want you to know the person in advance.
[15:34:53] <OdinYggd> That gives an unfair bias
[15:35:14] <witnit> circumstances call for bias
[15:35:26] <OdinYggd> Justice is blind.
[15:35:37] <witnit> doesnt make it more just
[15:35:45] <OdinYggd> If you have any connection to the defendant you are excused from the jury for that case
[15:35:52] <witnit> I didnt
[15:36:11] <witnit> they werent a fan of my stance on vigilante justice
[15:36:12] <OdinYggd> The point of the jury is given only the facts presented is there enough evidence for a yes or no
[15:36:23] <OdinYggd> Missed oppertunity then
[15:36:42] <OdinYggd> Getting paid to sit there and listen to some real world scenarios calling for a logical approach
[15:36:44] <witnit> right, which in this particular case i would not be comfortable serving with
[15:36:57] <witnit> im worth more money than what they would pay me
[15:37:11] <witnit> wouldnt judge someones life for a paycheck anyhow
[15:37:15] <OdinYggd> Where I live at least they match your wages if oyu would have missed work
[15:37:20] <OdinYggd> And if you are unemployed, you get minimum wage
[15:37:25] <witnit> typical
[15:37:45] <OdinYggd> My wife made a lot of money doing it for a couple weeks
[15:37:49] <CaptHindsight> "yer honor, I kin tell just by lookin in his eyes if he's guilty or not"
[15:37:55] <witnit> you should be compensated the same as what the judge is payed
[15:38:09] <witnit> imo
[15:38:11] <OdinYggd> All of the cases she heard were petty stuff like dudes not paying child support or caught shoplifting from walmart
[15:38:20] <witnit> this was much different type of case
[15:38:23] <OdinYggd> High profile stuff gets its own jury just for that case
[15:38:47] <witnit> violent case retaliation from what I could gather
[15:39:18] <OdinYggd> egh, those get a bit ugly
[15:39:40] <OdinYggd> You appeared when summoned and they simply chose not to seat you on a jury?
[15:40:12] <CaptHindsight> Do let let you out of jury duty if you call on the invisible angry man in the sky for help?
[15:40:33] <OdinYggd> Nope.
[15:40:47] <SpeedEvil> I got out of jury duty by simply explaining my health issues.
[15:40:56] <SpeedEvil> I'd love to have done it
[15:40:58] <OdinYggd> If you do anything disruptive or obviously with the intention of getting out, you get charged with contempt of court
[15:40:59] <_methods> just say the magic words
[15:41:03] <_methods> jury nullification
[15:41:16] <OdinYggd> but they will let you out for health reasons, if you have a sufficiently important job like a firefighter or a doctor
[15:41:20] <_methods> if you even mention that they basically kick you out of the court house
[15:41:24] <OdinYggd> and a couple other scenarios
[15:41:45] <OdinYggd> Once you've been summoned, as long as you show up even if oyu don't get seated as a juror they won't call you again for roughly 7 years
[15:42:03] <OdinYggd> Try to get out of it though and oyu get called again- as a defendant instead of a juror
[15:42:41] <OdinYggd> Now that I think about it, its been a while since they've called me.
[15:42:54] <OdinYggd> Oh well. Don't ask maybe I have a few more years left
[15:43:24] <OdinYggd> Last time they sent for me I reported as ordered, but the case settled perhaps 10 minutes before juror selection began
[15:43:26] <CaptHindsight> is disruptive anything like inappropriate behavior in grades K-12?
[15:43:32] <witnit> providing it were a different type of case I would have been fine with it, this particular one I was uncomfortable with
[15:43:57] <OdinYggd> Well, as long as you reported when ordered and were told that you could go home again you're in the clear for 7 yeras
[15:43:59] <OdinYggd> *years
[15:44:18] <OdinYggd> Not showing up or intentionally being an ass to get kicked out brings bad news
[15:44:39] <CaptHindsight> define ass
[15:44:50] <OdinYggd> Most of what you're thinking CaptHindsight
[15:45:42] <OdinYggd> In fact I'd bet anything that would get speedevil to kneecap you in ##electronics would get you in a heap of trouble at the courthouse
[15:45:48] <CaptHindsight> so if you respectfully disagree with the law or rules in question that is contempt?
[15:46:03] <OdinYggd> depends on how you express it
[15:46:04] <witnit> well all the other jurors were agreeing with my answers and just using my answers when they attorneys were asking them the same thing so I feel like I had plenty of support. no its not, I told them i disagree
[15:46:14] <OdinYggd> If you're willing to takl it out calmly and explain why you feel that way, they might be willing to hear it.
[15:46:20] <OdinYggd> Going off on people like a brat will get you arrested
[15:46:37] <witnit> its like even if you know the law is there if you dont agree with the law they would rather know before they pick you
[15:46:48] <OdinYggd> It is after all the jury that suggests how a law be applied to a situation
[15:46:50] <CaptHindsight> you must be used to being mostly around the average public then
[15:46:54] <OdinYggd> So if the law doesn't apply, its part of your job to say so
[15:47:08] <OdinYggd> Usually the lawyers will pick up on that before you do though
[15:47:45] <witnit> yeah it doesnt really matter what your opinion is, but they clearly are looking for people who would keep the jury from coming to a verdict
[15:48:09] <witnit> errr gtg back to the shop busy day!
[15:48:20] <CaptHindsight> witnit: depends on the side
[15:48:25] <witnit> ^
[15:48:27] <CaptHindsight> thats the fun of it
[15:48:38] <witnit> if I wanted picked I would have lied to them
[15:48:48] <witnit> but i didnt want to judge that kind of case
[15:50:08] <CaptHindsight> best way to win is not play
[15:51:24] <OdinYggd> But you are required by law to show up when summoned.
[15:51:37] <OdinYggd> Beyond that, it is up to the lawyers if you will actually be seated as a juror
[15:52:14] <OdinYggd> each lawyer wants jurors likely to favor their side of the case after all, and the goal is a process of elimination until a roughly fair compromise is reached
[15:52:15] <CaptHindsight> I used to bring my kids with and ask where the day care was
[15:53:54] <CaptHindsight> they didn't even let me in
[15:54:06] <_methods> hehe
[15:54:22] <SpeedEvil> CaptHindsight: you need to understand that your ability to object to the process - even respectfully - is constrained.
[15:54:39] <OdinYggd> And you live dangerously with stunts like that.
[15:54:55] <SpeedEvil> CaptHindsight: you can't make reasoned arguments in all cases and some reasoned objections may amount to contempt of court.
[15:55:05] <_methods> just go out and commit a couple felonies
[15:55:08] <SpeedEvil> Similarly with speaking to people you are told you cannot.
[15:55:10] <_methods> then you never have to worry about it again
[15:55:19] <CaptHindsight> since it's off the rails, it's best to avoid it
[16:03:08] <CaptHindsight> it makes no sense that after you have paid for any felonies that you still loose your rights
[16:03:26] <CaptHindsight> it makes sense when you want an unfair system
[16:04:19] <XXCoder> yeah some groups keep trying to deny certain groups of people ability to vote
[16:04:30] <XXCoder> the reasoning is olvious.
[16:05:33] <CaptHindsight> with the highest incarceration rate of any country how are ex felons not peers?
[16:06:06] <CaptHindsight> how did we end up with a for profit prison system?
[16:09:57] <XXCoder> poticitians out to make money rather than create fair and balanced system for everyone.
[16:10:15] <XXCoder> CaptHindsight: we got HUGE miliary-industry complex due to this too.
[16:10:45] <CaptHindsight> Eisenhower warned of this in the 50's
[16:11:04] <XXCoder> just one plane project, if spent on college intead, would give everyone free PHD college for 100 years, and give everyone a free house with just leftovers after that.
[16:11:24] <CaptHindsight> but they don't matter
[16:11:35] <CaptHindsight> just people to abuse
[16:12:11] <CaptHindsight> and after you abuse them enough they even defend and feel comfortable with their abusers
[16:12:58] <CaptHindsight> prefer to be around, vote for, work for and follow
[16:13:12] <XXCoder> ah its called F-35
[16:18:47] <_methods> once donald is running this shit show we're going to get some good deals
[16:19:04] <XXCoder> if
[16:19:09] <yasnak> pls no
[16:20:11] <XXCoder> person who dont know history is doomed to repeat it. person who knows history to doomed to see it repeated by person who dont know history.
[16:20:13] <_methods> man you guys are already sick of winning
[16:20:29] <_methods> wise words XXCoder
[16:21:04] <CaptHindsight> hell yeah Trump macht frei!
[16:21:24] <_methods> hair shirts for all the trumpeters
[16:21:58] <_methods> you know how he gets his hair so perfect?
[16:22:02] <_methods> he does it himself
[16:22:14] <_methods> you can't trust anyone else with hair like that
[16:22:30] <CaptHindsight> orange is a sign of royalty
[16:22:32] <XXCoder> its amazing combover I'll grant you that

[18:18:10] <als> I just came across a could be bug if you start @ the beginning of a program Execute next line [T] and press T twice before it gets to the end of the first line it will chew up 2 lines of gcode if you start with ,Begin executing the current file [R] then pause and Execute next line [T] and press T twice it will not do 2 lines
[18:21:36] <CaptHindsight> als: try posting the bug if it's not already on the mail list
[18:22:12] <als> to the list or bug tracker
[18:22:41] <andypugh> Either.
[18:23:03] <als> will do
[18:23:25] <andypugh> But i think we need a clearer description of what you did, what happens and what you think should happen.
[18:24:01] <andypugh> I would expect the second behaviour to be correct?
[18:24:38] <andypugh> It is plausible that the OS GUI manager is queuing keystrokes, and that there isn’t much we can do about it.
[18:25:53] <als> well if you start as I said press T twice anytime in the middle of the line it will run two lines also if you just use the arrow on axis you get the same thing
[18:27:57] <andypugh> I have to admit that I have never tried to single-step.
[18:29:00] <andypugh> But I would think that correct behaviour is to ignore step prodding unless it is in the paused state?
[18:29:39] <skunkworks> yes - if you hit t 3 times it runs the next 3 lines..
[18:29:46] <skunkworks> I don't know if that is a bug or not
[18:29:56] <skunkworks> seems like a os thing
[18:30:37] <skunkworks> If you had a physical button - I don't think you would have the same behavior (hooked to halui)
[18:46:14] <andypugh> als: Interesting test, do you feel inclined to try it?
[18:49:34] <andypugh> You don’t need a physical button. This is going to sound wierd, but you could use a sim-pin GUI element to poke the HAL pin in halui and that will either work exactly like a physical button or like a GUI button. which might sound useless, but if the behaviour is different it tells us something. (If it is the same it tells us nothing). http://linuxcnc.org/docs/2.7/html/man/man1/sim_pin.1.html
[18:49:55] <als> ya tomorrow
[18:50:17] <als> it does on a sim gui for sure
[18:51:09] <skunkworks> yes - if you click the single step button multible times - it remembers how many. Probably should be blocked while in motion
[18:51:55] <als> at least a warning in the docs
[18:52:23] <andypugh> sim-pin is a GUI element that automatically links to a HAL pin. It’s like a Halmeter that controls a pin rather than displays the value. (Actually, it can do both).
[18:58:56] <als> I'll check my physical button tomorrow
[19:00:38] <andypugh> It could be absolutely any button that is available on your system. You can reconfigure HAL on the fly.
[19:01:36] <andypugh> On a running system, open a teminal and type “halcmd -kf” and you can then unlink, link, setp, net in any way you want.
[19:01:37] <als> i have one in gui form and it does as explained
[19:02:11] <andypugh> Does it drive the Halui pin? (ie interact in the HAL layer)
[19:02:19] <als> yes
[19:02:31] <andypugh> Interesting.
[19:03:02] <als> but you get the same result using [T]
[19:03:57] <andypugh> It might be fun to halscope motion.program-line and the halui pin, that _should_ show if the GUI/OS is buffering button presses.
[19:14:03] <enleth> https://www.youtube.com/watch?v=nzLQCOjrywk - VFD works with the TNC control. Only thing left is a speed adjustment potentiometer on the factory panel.
[19:16:17] <enleth> Then some minor fixes (one of the handwheel detection switches is flaky and interrupts sometimes, some wiring need tidying up) and I can actually start wiring 7i77 in there
[19:20:44] <andypugh> Why you messing with that old school TNC? Yu could be using nearly-as-old LinuxCNC
[19:21:16] <enleth> it's actually *really* comfortable to use
[19:22:15] <enleth> and I'm still taking care of some electrical/mechanical stuff in the machine, so a known good control that is properly fitted to the machine helps in debugging
[19:22:54] <andypugh> It looks to work well. It’s pretty quick-moving.
[19:26:24] <enleth> the initial run to the center of the table was 3000mm/min
[19:27:52] <enleth> but it will do up to 5000 just fine
[19:28:12] <enleth> and I think I could get it to run even faster
[19:29:04] <enleth> anyway, I'm keeping the TNC
[19:29:21] <enleth> if possible, that is
[19:30:09] <enleth> even with linuxcnc, it's still going to be faster for the 5 minute one cut odd job
[19:32:30] <enleth> and in the worst case, it's a solid, highly readable DRO for manual work
[19:37:27] <enleth> heh, tried to push it to 7m/min and it didn't cooperate
[19:38:01] <enleth> I mean, it tried, then detected a gross positioning error
[19:40:39] <enleth> OK, there are positioning problems even at 5.5m/min on the X axis
[19:41:08] <enleth> not surprising, the X drivetrain is most complex
[19:41:51] <enleth> and the dovetails longest, the X servo would obviously experience the most friction
[19:42:25] <andypugh> That’s an interesting “obviously”
[19:43:01] <andypugh> Obviously the X dovetail has the lowest contract pressure and the lowest friction :-)
[19:43:53] <andypugh> The Y is moving more total mass, so probably can’t do the same acceleration as X.
[19:44:08] <enleth> well, you may just as well be right, I'm not about to try to measure the friction in there
[19:44:31] <enleth> but Y was actually capable of 6m/min
[19:44:56] <andypugh> Oh, no, I think I am probably wrong. I just don’t think it is ‘obvious”
[19:45:24] <andypugh> Gearing and leadscrew pitch matter a lot too.
[19:45:57] <Sync_> it probably is the same on the axis
[19:46:06] <Sync_> not sure if it has the lowest friction
[19:46:12] <enleth> I assumed the coefficient of friction is similar for X and Y dovetails and Y pushes 44% more mass than X
[19:46:26] <Sync_> from a standstill it should have the most, as it has the most surface area
[19:46:38] <enleth> but the dovetail contact area for X is more than 2x bigger than Y
[19:47:04] <andypugh> Yes, I expect it does come down to viscous drag on the oil film.
[19:47:48] <enleth> interestingly, the positioning error was detected a few seconds after the motor got up to speed
[19:48:12] <enleth> judging by the sound, it wasn't accelerating anymore at that point
[19:48:25] <andypugh> I don’t question the conclusion, particularly. But if someone told me that it was the other way round I am sure I could think of anothe “obvious” explanation. :-)
[19:49:08] <enleth> anyway, it appears that 5m/min is the practical limit
[19:49:17] <enleth> not that it matters much, that's plenty enough
[19:49:23] <andypugh> enleth: That sounds about right. It was at full speed, and lagging ever so slightly below commanded speed.
[19:50:05] <enleth> could be that the control wasn't as sensitive to errors as long as the motor was accelerating
[19:50:13] <enleth> no idea how the math is done internally
[19:50:14] <andypugh> Well, if 6m/min took seconds to trip, 5.95m/min would probably be fine.
[19:50:41] <andypugh> But give it a heavy worpiece, and all bets are off.
[19:50:41] <enleth> it tripped at 5.5 too, but only about halfway through
[19:50:51] <enleth> yeah, that was an empty run
[19:51:18] <andypugh> You probably should put the biggest thing you have on there for resting.
[19:51:22] <andypugh> (testing)
[19:52:04] <enleth> as far as I remember, specs for the machine claim that the table will hold something like 150kg
[19:52:13] <enleth> or maybe it was 200?
[19:52:21] <enleth> no less than 150 for sure
[19:54:18] <andypugh> So, if you need more than two people, start wondering?
[19:54:18] <Sync_> the linear motor machines have a parameter for the part weight
[19:54:27] <Sync_> soe they can optimize the accels and such
[19:54:52] <enleth> I could load it up with a bunch of 10kW autotransformers or a vacuum pump, but I can't be arsed to bring out the crane at the moment
[19:55:08] <enleth> so testing under load will have to wait
[19:58:19] <enleth> no point in even trying to lift all that crap without a crane, the pump is a bitch to move despite being on a wheeled base
[19:58:53] <andypugh> Use people, they are self-loading. If annyongly too squishy to rigidly couople.
[20:00:11] <Sync_> heh, that reminds me of the e24 gearbox I moved friday
[20:00:41] <enleth> interestingly, the operator's manual doesn't say anything about not running the mill with people on the worktable
[20:00:44] <enleth> weird, eh?
[20:01:09] <Sync_> a friend of mine wanted to move it with two persons, but I already had managed to shove it into the shelf
[20:04:00] <Sync_> it's actually not too heavy, about 65kg or so
[20:08:34] <Sync_> ah andypugh, had fun at work today
[20:09:25] <Sync_> noticed that the lead windows were cracked on my machine, super annoying to swap
[20:10:19] <andypugh> Yeah, 65kg is managable. I found myself panicking with 85kg still only half way across the room and wearing slippers, a little whie back.
[20:10:46] <andypugh> Lead or lead-glass?
[20:10:51] <andypugh> Can lead crack?
[20:11:31] <Sync_> leaded glass
[20:11:46] <Sync_> the problem is, LN2 runs into them
[20:11:47] <andypugh> (I exect that lead can crack in very thick sections, it is an interesting fact that any ductile material is capable of brittle fracture if it is thick enough)
[20:11:52] <Sync_> and due to the thickness they will crack
[20:12:27] <Sync_> the quartz/boro windows below them have never cracked
[20:12:30] <andypugh> Being cracked _probably_ doesn’t affect the shielding.
[20:12:47] <andypugh> But I have to say that
[20:12:54] <Sync_> the guideline says they have to be "intact"
[20:12:58] <Sync_> so we replace them
[20:13:04] <andypugh> that isn’t a “probably” I would chase very far.
[20:13:11] <Sync_> even if they only have an internal shell crack
[20:13:22] <Sync_> they still work fine, I measured it
[20:13:39] <Sync_> the whole thing is a joke here
[20:13:47] <andypugh> Indeed, any crack with a bend in it isn’t there…
[20:14:06] <Sync_> we only have stray radiation emitters
[20:14:16] <andypugh> But I suppose the danger is a second crack and then a section dropping out.
[20:14:35] <Sync_> the highest voltage we have in the systems is around 25kV
[20:16:44] <Sync_> but because some of the earlier guys responsible fucked up hard we have to play the ball really low now
[20:18:46] <Sync_> the windows are fun, they are incredibly heavy for their size :D
[20:18:53] <Sync_> (no shit)
[20:18:58] <Sync_> but still fun
[20:20:10] <Sync_> oh, I also lied, one of the viewports has cracked before
[20:20:21] <Sync_> but that was due to the phd student throwing a spanner in there
[20:20:28] <Sync_> sounded like a gunshot
[20:21:24] <Sync_> combined with the alarm going off because the turbos stalled
[20:23:54] <Sync_> I talked to a pfeiffer engineer and he told a story of when something failed in one of their big pumps and the rotor crashed hard without coming apart, it sheared it clean off the flange
[20:30:36] <yasnak> Forgot to do their monthly inspections on the rotary girder eh
[20:30:42] <yasnak> Big no-no
[20:35:13] <Sync_> vat
[20:35:55] <yasnak> wow, nobody? okay. i'm here all week...
[20:36:33] <yasnak> PS: Looks like trump got Florida. Who knew there was idiots in Florida? :P
[20:37:35] <PetefromTn_> Of course there's idiots in Florida...Hillary won there
[20:37:41] <yasnak> ;/
[20:37:49] <yasnak> I tried my best man
[20:38:44] <PetefromTn_> Well the Cincinatti and the Standard Modern are no longer in Tennessee ;)
[20:41:11] <Sync_> :)
[20:42:49] <Sync_> did you already have a house in FL or are you just storing them?
[20:42:57] <yasnak> Wait, where in FL?
[20:43:29] <yasnak> I mean if you don't mind...
[20:44:53] <PetefromTn_> we do not currently have a house in florida but we are actively looking
[20:45:13] <PetefromTn_> the machines are going to be put into a storage unit until we are able to get settled into our new home
[20:45:38] <yasnak> Did you do it yourself or hire riggers?
[20:46:04] <PetefromTn_> We are moving to the Treasure coast area of florida about central east coast
[20:46:05] <yasnak> I've got pictures from when we moved ours. I can tell you this. OIL THE BEDS
[20:46:48] <PetefromTn_> I hired a guy with a very heavy duty dovetail hydraulic fifth wheel trailer and a Chevy heavy duty dually truck
[20:47:20] <PetefromTn_> we agreed to help each other load it up and for that I got what I feel is a very reasonable price for the shipping
[20:47:24] <Sync_> those 5th wheel trailers scare me
[20:47:45] <PetefromTn_> I have no idea why but not surprised you would say that.
[20:48:13] <PetefromTn_> this was a VERY serious trailer and had zero issues loading the machine or lifting it.
[20:48:52] <PetefromTn_> Gotta go...
[20:48:58] <Sync_> the trailers are probably fine
[21:11:32] <pink_vampire> this is very excited moment for me now.
[21:13:29] <pink_vampire> my friend connect the first wires in the panel!!!!
[21:30:58] <jdh> if you clipped your nails, you could connect wires yourself.
[21:43:58] <yasnak> lol
[21:44:23] <yasnak> Idk how you work with those, let alone still have the ability to see.
[21:51:31] <pink_vampire> I know.. but if I have to decide nails vs cnc control panel.. long nails are muuuch more important.
[22:07:33] <pink_vampire> yasnak: jdh ^
[22:56:24] <yasnak> priorities ;)
[23:08:11] <ljjms638> LinuxCNC2.7.4 can't support EtherCAT very well. I did it failed . Lcec invalid paremeters .Anybody ,success?
