[01:58:21] <mase-tech> Good morning people :)
[02:02:10] <Deejay> moin
[02:02:16] <mase-tech> servus
[02:05:46] <maxcnc> moin from a ice cold and road slip Germany
[02:06:01] <Deejay> ah, the krauts :)
[02:06:13] <Deejay> hmm, too slippy for him ;)
[02:14:00] <mase-tech> Good morning
[02:15:10] <mase-tech> 30% of america is german progeny
[02:15:20] <mase-tech> so I wonder why the talk english
[02:16:45] <archivist> because rest english
[02:16:49] <mase-tech> wrong
[02:17:11] <mase-tech> lot of italian
[02:17:15] <mase-tech> spanish polish
[02:17:19] <mase-tech> everything
[02:17:26] <mase-tech> chinese
[02:17:29] <Deejay> most people on eartch speak chinese ;)
[02:17:33] <Deejay> *earth
[02:17:35] <mase-tech> thats right
[02:20:14] <mase-tech> Hey trump is german too
[02:20:16] <mase-tech> :D
[02:20:43] <mase-tech> Budweiser is german beer
[02:22:09] <mase-tech> We are family :D
[04:57:10] <XXCoder> heys
[05:15:52] <malcom2073> hi
[05:17:24] <XXCoder> whats up
[05:21:50] <Jymmm> XXCoder: Nada... http://www.amazon.com/Haribo-Sugar-Free-Gummy-Bears/product-reviews/B008JELLCA
[05:22:05] <XXCoder> heh read that before
[05:23:48] <Jymmm> =)
[05:24:09] <XXCoder> I bet its GREAT for colon cleaning :P not that it actually needs to be cleaned
[05:26:23] <XXCoder> most of em I'm sure are bullshit stories
[05:26:26] <XXCoder> but great read anyway
[05:30:20] <XXCoder> Jymmm: too bad I didnt have any to swnd to oregon terrorists when they asked for snacks
[05:53:38] <Jymmm> asked for snacks?
[05:54:45] <XXCoder> yeah
[05:55:00] <XXCoder> they literally asked for snacks.
[05:55:13] <XXCoder> someone sent em lighthouse/penis gummies
[05:55:19] <XXCoder> tons sent em dilios though
[05:55:36] <Jymmm> by terrorists, you mean hipsters?
[05:55:49] <XXCoder> lol nope
[05:57:03] <Jymmm> bummer
[07:21:44] <pink_vampire> hi
[07:21:59] <pink_vampire> XXCoder: http://i.imgur.com/zenoEUo.png
[07:43:04] <jthornton> aww crap, clonezilla "fixed" the sectors something or other and now it won't clone to an identical hd because the size is different
[07:45:26] <enleth> uh, use dd?
[07:50:31] <jthornton> http://www.howtogeek.com/howto/19141/clone-a-hard-drive-using-an-ubuntu-live-cd/
[08:00:40] <jthornton> Note: while you can copy a smaller drive to a larger one, you can’t copy a larger drive to a smaller one with the method described below.
[08:01:11] <jthornton> that seems to be a problem for me the disk with the data is for some reason now a tiny bit bigger than a new one
[08:04:50] <skunkworks> the normal rube goldberg way to do it - > restore the image on a larger drive -> use Gparted to shrink the partition -> make a new image of the smaller partition
[08:06:42] <jthornton> then use dd?
[08:09:58] <jthornton> I have the original drive, I'm just trying to clone it to a new drive
[08:20:26] <_methods> even dd won't let you copy a larger drive to a smaller one
[08:20:29] <_methods> well it will let you
[08:20:31] <_methods> but it will fail
[08:24:55] <enleth> question is - how it fails
[08:25:10] <enleth> and whether he needs the last sector
[08:25:15] <_methods> true
[08:25:55] <_methods> i don't think i've ever intentionally tried to copy a larger drive to a smaller one so i'm not sure what would happen
[08:26:14] <jthornton> for some reason it changed the number of cylinders
[08:26:22] <enleth> it will copy just fine up to the target capacity
[08:27:02] <enleth> jthornton: that's what you get for using shitty overcomplicated tools
[08:28:35] <enleth> jthornton: how much larger is the copy? is it a raw data file or some proprietary format?
[08:29:10] <enleth> it may have just been padded at the end
[08:29:54] <jthornton> both hard drives are 80gb but the one with the os on it has 9729 cyl and the new empty one has 9726
[08:30:30] <enleth> there's no such thing as cylinders on modern hdds
[08:30:47] <enleth> it's emulated
[08:30:54] <jthornton> I booted from a third disk and am viewing them with gparted
[08:31:41] <enleth> ah, so you have both and you can copy directly?
[08:31:48] <jthornton> so I have the source drive dev/sdc and the target drive dev/sdb
[08:32:22] <jthornton> yes, I just got all them plugged in
[08:33:16] <enleth> switch units in gparted to blocks
[08:33:48] <enleth> see what's the size difference in blocks
[08:35:25] <enleth> check whether the end of the last (location-wise, not index-on-list-wise) partition on the source hdd ends up within the size of the target hdd
[08:36:27] <enleth> if so - dd away and ignore the error that will appear when it reaches the last blocks, you don't need them anyway
[08:37:25] <enleth> if not - shrink the last paetition as needed to have it end within capacity of the target device
[08:38:06] <jthornton> I don't see an option to switch units
[08:38:26] <enleth> must be somewhere
[08:40:23] <enleth> well, you could do all of the above with sectors as well
[08:42:55] <enleth> just make sure the data you actually need fits the target drive and note that many filesystems store internal data at the end of the partition so you don't want to truncate one
[09:04:17] <miss0r> I am looking into doing metal 'bluing'. What is looking best to me, is having a pot on a gas stove outside, and having some sort of mixture in there boiling with the part in there. I just can't seem to find a good recepie. Do you guys have experience doing this/can reccomend a recepie?
[09:17:33] <archivist> no recipe at all, just careful and accurate heat
[09:18:16] <miss0r> indeed. for the bluing process :) I guess bluing isn't even the correct term: I want the black surface :)
[09:19:11] <archivist> chemical black is often cold, just buy the chemical
[09:19:37] <archivist> I made a kiln for blue
[09:19:38] <minibnz> heating up metal until it turns blue is not the process.. there is a chemical that does the blueing without overheating the metal. they use it on gun barrels that cannot be done via heat alone as it would stuff the barrel..
[09:20:03] <archivist> google gun bluing
[09:20:08] <miss0r> minibnz, I have some bluing chemical
[09:20:09] <archivist> a grey
[09:20:10] <minibnz> and the blueing will chip and wear off..
[09:20:47] <minibnz> yeah you can buy the touchup kits.. but for whole parts the process is a little different and its a bit better quality
[09:21:29] <minibnz> actually i should probably get my guns out and give them a bit of a look over i havent had them out for a few months..
[09:21:37] <archivist> the dull black on a spanner is not the same as a gun blue either I think
[09:22:03] <minibnz> nah that is forge slag or something
[09:22:07] <miss0r> Like when you get a new drillset - they have this black oxidation all over. I want to be able to do that
[09:22:24] <minibnz> yup
[09:22:27] <minibnz> spot on..
[09:22:51] <miss0r> what is that called exactly?
[09:23:18] <archivist> that black is what I am talking about, different from the grey of a gun
[09:23:51] <minibnz> black phosphate?
[09:24:06] <miss0r> black oxide
[09:24:38] <miss0r> I saw a video of a guy having some water on a stove, he mixed in some powder/granulate of some sort and then heated it up, and dumped in his part
[09:24:43] <miss0r> that gave a great result
[09:24:44] <miss0r> brb
[09:24:59] <archivist> https://en.wikipedia.org/wiki/Bluing_%28steel%29
[09:27:19] <minibnz> selenium dioxide based compound
[09:29:11] <minibnz> thats for cold blueing.. cant find the mix for the boil method..
[09:29:50] <minibnz> the hot mix is called traditional custic black..
[09:30:04] <archivist> that wiki article seems to have missing stuff, the plain blue clockmakers use is not there
[09:30:52] <archivist> I becoming distrusting of wikipedia "accuracy"
[09:31:23] <minibnz> http://www.practicalmachinist.com/vb/gunsmithing/blueing-126689/ this link has the chemical by brand name
[09:32:13] <archivist> this is clockmaking style http://www.collection.archivist.info/searchv13.php?searchstr=exam
[09:32:43] <archivist> no chemicals except heat and air
[09:40:14] <minibnz> http://www.brownells.com/gunsmith-tools-supplies/metal-prep-coloring/metal-bluing/hot-salts-bluing-systems/bluing-system-kit-prod1113.aspx
[09:40:36] <minibnz> thats a kit for sale.. looks llike fume blueing..
[09:40:47] <minibnz> $2250
[09:41:07] <miss0r> :o
[09:41:15] <miss0r> I was hoping for something as cheap as kitchen salt
[09:41:28] <miss0r> if that statement is true, it's alot of kitchen salt
[09:41:55] <minibnz> i guess you need the right salts for fume blueing. you heat them the vapor hits the metal and makes black rust..
[09:44:52] <minibnz> normal kitchen salt would give you redding.. not blueing.. ie rust :)
[09:46:43] <archivist> http://www.mmsonline.com/articles/do-it-yourself-cold-blackening
[09:48:24] <archivist> http://www.hubbardhall.com/chemical-applications/metal-coloring/room-temp-metal-coloring/
[09:49:48] <miss0r> I just like the part about boiling stuff.. it all seemed so simple
[09:51:46] <minibnz> just boil it in custic soda?
[09:52:16] <minibnz> 140'c
[09:57:38] <FinboySlick> miss0r: https://www.youtube.com/watch?v=NhjiIPohUyw might be of interest if you haven't seen it yet.
[10:02:55] <miss0r> FinboySlick, Not exactly :) I am looking for a chemical way of doing black oxide
[10:03:51] <FinboySlick> miss0r: Use a sharpie, nobody will notice ;)
[10:03:59] <miss0r> ;)
[10:26:28] <Jymmm> Sprinkle some mold spores, it'll be black on no time!
[10:26:33] <Jymmm> in*
[11:23:03] <Jymmm> what is the purpose of the tank on this pump? http://www.harborfreight.com/1-hp-shallow-well-pump-with-stainless-steel-housing-920-gph-69302.html
[11:25:15] <archivist> pumps often have an air chamber to even out the hammer/pulsations
[11:25:28] <Jymmm> ah
[11:26:52] <Jymmm> We have a 220V pump on the house water at the meter, but it has siezed. There is a tank there with a bladder in it.
[11:28:09] <Jymmm> street --meter--checkvalve--pump--Tee'd_tank--house
[11:28:53] <archivist> almost no uk houses need pumps, uk mains pressure is sensible
[11:29:01] <Jymmm> I think it was called an "expansion tank", but I'm not sure it's exact purpose/function in this case.
[11:29:56] <Jymmm> archivist: I'm just too close to the source... a one million gallon tank that's only 50ft or so away, so I only get 21-24 PSI
[11:30:29] <Jymmm> not enough elevation change
[11:30:54] <archivist> when you shut a valve internally mass continues to flow, the tank takes that istead of you getting water hammer
[11:31:46] <Jymmm> Oh, so nothing todo with hot water heater or anything like that?
[11:32:03] <archivist> but, see ram pump where that flow is actually used to do the pumping
[11:32:24] <Jymmm> (I see expantsion tanks used on/near hot water heaters sometimes, but no clue why)
[11:32:33] <archivist> no it is a "capacitor" smoothing the flow
[11:32:33] <Jymmm> Ok, ram ump I understand.
[11:32:40] <Jymmm> gotcha.
[11:35:02] <Jymmm> Been dealing with the 21PSI for a while, but recently finding that the added pressure would be nice. Not sure if attmpting to repair the existing pump (motor hums so I think it's the pump itself that's siezed) or not. I tried lookng up the maker, but not much luck.
[11:36:38] <Jymmm> I'm not even sure what KIND of pump to replace it with as there seems to be many kinds out there.
[11:36:57] <archivist> capacitor may have failed
[11:37:32] <Jymmm> Hmmm, shit if it that simple...
[11:38:32] <Jymmm> I'll look again once I get rid of all the black widows in the pump's doghouse
[11:39:19] <Jymmm> I found out that I needed the extra pressure when I tried spraying under the eaves and the water stream couldn't reach.
[11:39:52] <Jymmm> I'm using an in-line insecticide sprayer
[11:40:46] <Jymmm> They about asked for DNA/fingerprint sample when I bought this "controlled" stuff
[11:42:01] <minibnz> sounds like you got the good stuff.. maybe you can make something interesting from it?
[11:42:23] <Jymmm> minibnz: Yeah.... NOT! They have my info, remember?
[11:43:10] <minibnz> they already suspect you... this way you can get it over quickly by saying here it its... rather than days of i didn't do anything...
[11:43:20] <Jymmm> lmao
[11:44:12] <Jymmm> Well, ornage/blue borg dont even carry the "retail" versions anymore. And a quart of the retail stuff is $50
[11:44:35] <Jymmm> at 2.4% concentration
[11:45:04] <Jymmm> The stuff I got is the same, but $34 and 9.8% concentration
[11:45:48] <pink_vampire> how much freeze clamp should cost?
[11:46:01] <CaptHindsight> Pyrethrum?
[11:46:04] <Jymmm> The farmers swear by it, and it's suppose to kill everything on my list =)
[11:46:19] <Jymmm> CaptHindsight: No, BiFenthrin
[11:47:03] <CaptHindsight> Bifenthrin is a pyrethroid insecticide
[11:47:18] <Jymmm> CaptHindsight: and that means what?
[11:47:53] <pcw_home> namby pamby biologic
[11:48:38] <CaptHindsight> toxic to aquaman and other fish
[11:48:47] <pcw_home> Chlordane it and sterilize the area for years (and maybe yourself)
[11:49:21] <CaptHindsight> can you buy that on California?
[11:49:30] * Jymmm kill list: Black Window, mosquitos, red ants, black ants, wasps, yellow jackets, tarantula hawks
[11:49:35] <minibnz> petrol and a match is cheap :)
[11:50:08] <pcw_home> no its been banned for many years (carcinogen among other things)
[11:50:20] <Jymmm> Malathon 50% is back!
[11:50:27] <Jymmm> off the ban list that is
[11:50:35] <Jymmm> in Calif
[11:50:43] <pcw_home> parkinsons Here I come
[11:50:56] <minibnz> some guy got bitten on his dick by a red back spider in sydney today.. its a member of the black widow..
[11:51:03] <minibnz> family.
[11:51:21] <Jymmm> CaptHindsight: I'm at 3000ft, the closest lake downstream (so to speak) is 10 miles
[11:51:23] <minibnz> was in a porta loo sat down for a paid shit and got bitten...
[11:51:32] <pcw_home> not molesting a spider?
[11:51:55] <t12> https://pbs.twimg.com/media/ChC6pHWUoAAQPZc.jpg:large
[11:52:03] <Jymmm> PAID?
[11:52:11] <Jymmm> oh, on the job?
[11:52:23] <minibnz> yeah was at a worksite.
[11:52:42] <minibnz> i wonder what the compo payout would be for that..
[11:52:48] <Jymmm> t12: and for use that dont read russian?
[11:52:49] <minibnz> ohas and all that..
[11:52:54] <Jymmm> us*
[11:53:08] <minibnz> its a nice earthing job thou..
[11:53:09] <Jymmm> oh ground... lol
[11:53:17] <CaptHindsight> t12: it did say Earth ground
[11:53:24] <Jymmm> I couldn't tell what was in the cup =)
[11:54:48] <CaptHindsight> http://www.bbc.com/news/world-australia-36136635
[12:14:56] <maxcnc> hi
[12:23:20] <Frank__14> helloo guys
[12:23:32] <maxcnc> hi
[12:30:50] <maxcnc> snow rain sun april weather the whole day here in germany
[12:31:41] <CaptHindsight> maxcnc: it's all the indecisive energy effecting the weather
[12:31:55] <Frank__14> people, i think i am in kind of a trouble, idk how big it is, but u might, so here it goes, i am measuring with my precision spirit level the flatness of my machined (shaped) gantry, (3feet 1.2mts) i already have the hiwin guides installed, but from the middle to one end i can see that it twists, 0.1mm from my measuraments, (rails are 15cm/6 inches apart, and i sit my spirit level in 1 block of each rail, and
[12:31:56] <Frank__14> from the middle to the end it moves 1.5gradients, measuring 0.1mm, i am measuring ok? sorry for the trobulee!
[12:32:03] <CaptHindsight> can't decide on which cereal, mill, channel on TV to watch
[12:32:44] <archivist> Frank__14, jack pack the legs to twist it straight
[12:33:44] <archivist> .1mm is not bad for the size and machine type though
[12:33:49] <awallin__> 0.1mm deflection in the middle of a 1.2m beam would not be surprising at all..
[12:33:50] <Frank__14> its solid structure, measuring only 130cm x 20cm do u think it still twists? they are 2 welded and stress relieved 100x100mm x6mm thick tubes together
[12:34:02] <Frank__14> and "machined"
[12:34:06] <Frank__14> awfull job they did
[12:34:30] <Frank__14> the thing is that its not deflection only, its twist along the rail i believe
[12:34:32] <maxcnc> i woudt leve it that amount
[12:34:48] <maxcnc> you wil never have a part like that mesurring size
[12:34:49] <archivist> the clamping will have twisted it, you can shim to correct it
[12:35:55] <maxcnc> mill a part in half worksize MDF wood and messure this after demounting
[12:36:26] <Frank__14> but how do u shim twist? if i shim up 1 rail the block will be in level with the other one, but i think the blocks wouldnt be straight
[12:36:43] <Frank__14> my biggest worry is to damage the rails, not the tolerances, i will only be cutting wood
[12:37:02] <archivist> for wood 1mm would be ok
[12:37:09] <Frank__14> hiwin only states 0.127mm for height tolerance, but says nothing on twist or other stuff
[12:37:17] <maxcnc> no need on wood to do somthing
[12:37:21] <archivist> .1 is very acceptable for wood
[12:37:32] <maxcnc> go for it
[12:38:06] <maxcnc> and you will not damage enithing
[12:38:30] <maxcnc> any
[12:38:54] <maxcnc> there will be noicy stuff befor somthing stalls or clamp or ..
[12:39:35] <Frank__14> ok
[12:39:38] <Frank__14> thatnks
[12:39:43] <maxcnc> NP
[12:39:51] <maxcnc> what spindel is mounted
[12:39:57] <maxcnc> or will be in place
[12:42:33] <maxcnc> CaptHindsight: might also be the cole smog
[12:43:57] <CaptHindsight> maxcnc: no it has to be something that doesn't involve actual science or logic
[12:44:58] <CaptHindsight> the coal smog theory only works in China
[12:54:55] <maxcnc> th people in china are may ,many more then the otheres in the cole regions
[12:56:59] <maxcnc> im off Gn8 soccer party tonight
[13:44:41] <pink_vampire> http://www.galco.com/buy/Cutler-Hammer-Div-of-Eaton-Corp/7685ST-15OD
[13:45:08] <pink_vampire> linux cnc can run on something like that?
[14:02:22] <Tom_itx> no
[14:02:32] <Polymorphism> 8000!!!!
[14:14:38] <djdelorie> is that how many days left until you buy something? ;-)
[14:14:50] <Polymorphism> xD
[14:15:40] <gregcnc> is that still funny?
[14:15:48] <gregcnc> i've been way
[14:15:50] <gregcnc> away
[14:17:31] <CaptHindsight> yes way
[14:22:47] <CaptHindsight> http://phys.org/news/2016-04-intelligent-brainless-slime.html
[14:23:55] <gregcnc> more on intelligence https://www.yahoo.com/news/driver-causes-major-accident-while-201900184.html
[14:24:31] <gregcnc> what's this bit about makerbot having someone else make their product?
[14:24:34] <FinboySlick> Interesting. Inversely, I know of at least two coworkers who do have brain cells buy are incapable of learning. I guess nature balances them out.
[14:27:03] <CaptHindsight> http://www.3ders.org/articles/20160427-botfactory-announces-squink-upgrade-that-lets-you-3d-print-multi-layer-pcbs.html
[14:28:06] <CaptHindsight> insulating ink (photopolymer) and a curing lamp.
[15:02:19] <Polymorphism> that looks interesting
[15:04:02] <XXCoder> pink_vampire: you made those labels?
[15:04:34] <pink_vampire> yes
[15:04:58] <XXCoder> cool
[15:05:19] <pink_vampire> too much time
[15:07:01] <XXCoder> yeah some simple stuff take so much time
[15:08:12] <Deejay> you are young and have enough time ;)
[15:08:26] <pink_vampire> 29..
[15:09:25] <gregcnc> I always say the retired people driving 15 under the limit have the rest of their life to get where they are going
[15:09:31] <XXCoder> man I really need to get phyical controls for my machine
[15:09:41] <XXCoder> using keyboard sucks for some stuff
[15:11:46] <pink_vampire> XXCoder: you need to use the mdi
[15:11:55] <pink_vampire> and make an HMI
[15:12:02] <pink_vampire> http://www.galco.com/buy/Cutler-Hammer-Div-of-Eaton-Corp/7685ST-15OD
[15:12:53] <XXCoder> short term I think I will use usb nes control
[15:12:57] <XXCoder> then later buy better one
[15:14:04] <pink_vampire> do you want an handle?
[15:14:50] <XXCoder> hmm forgot what its called
[15:14:57] <XXCoder> signal generator something
[15:15:04] <pink_vampire> encoder?

[15:15:55] <pink_vampire> something like that?
[15:16:03] <XXCoder> yeah thats one I plan to buy. one similiar anyway
[15:16:16] <XXCoder> and dang thats expensive. aliexpress is cheaper
[15:17:32] <pink_vampire> arduino + rotory encoder= handle in about 5$
[15:17:54] <pink_vampire> http://www.ebay.com/itm/Rotary-Encoder-Module-Brick-Sensor-Development-Board-Test-For-Arduino-New-D-/111861828395?hash=item1a0b7c0b2b:g:s~8AAOSwYHxWKJYS
[15:18:24] <XXCoder> it must be awesome being good on electrics and soldering
[15:18:57] <_methods> if you're on a budget and you want something that just works easy a usb numpad is great
[15:19:13] <_methods> you could probably get a bluetooth numpad too
[15:19:21] <XXCoder> thats a idea, I still have one I got for laptop while ago
[15:19:35] <_methods> i've never tried a bluetooth one
[15:19:36] <XXCoder> my budget is not tight but I'm cheap bastard though
[15:19:38] <jdh> looks unidirectional
[15:19:40] <_methods> but i use a wired numpad
[15:19:49] <XXCoder> http://www.aliexpress.com/item/Free-ship-CNC-Router-Mach3-USB-Handwheel-4-Axis-Pulse-50-PPR-Optical-Encoder-Generator-MPG/1000001416196.html

[15:19:59] <_methods> you can get a usb numpad on ebay for like $5
[15:20:11] <jdh> what do you do with an arduino
[15:20:29] <XXCoder> jdh: make pendant, if you have skills. I dont heh
[15:20:29] <jdh> methods: did you buy my lathe?
[15:20:36] <_methods> no not yet
[15:20:41] <_methods> you want me to go grab it?
[15:20:48] <pink_vampire> XXCoder: the link to AX is wired
[15:20:53] <jdh> I have skills. what do you do with the arduino
[15:20:55] <_methods> i might go check it out this wknd
[15:21:12] <XXCoder> pink it is, my machine is tiny so its fine. I dont know when I will buy it though
[15:21:19] <pink_vampire> http://i.imgur.com/RXNRYtX.png
[15:21:26] <XXCoder> or maybe I will go all in and buy wireless
[15:21:28] <pink_vampire> this is my controller ^
[15:21:55] <XXCoder> lol cool

[15:22:08] <_methods> free shipping
[15:22:08] <jdh> I'm bad about impulse buys. better I don't see it
[15:22:11] <_methods> $4.60
[15:22:16] <_methods> hahah
[15:22:20] <pink_vampire> soo funny this is old picture of my hand with short nails :)
[15:22:25] <_methods> well i was givin some local guys a chance to get it before i do
[15:22:31] * djdelorie has a hard enough time hitting tiny buttons WITHOUT long fingernails...
[15:22:52] <XXCoder> djdelorie: pink must be goddess with nails.
[15:23:01] <djdelorie> it's a talent
[15:23:17] <XXCoder> _methods: do you know it has full keyboard chip usually?
[15:23:28] <_methods> no idea
[15:23:34] <_methods> for $4 probably not lol
[15:23:37] <XXCoder> meaning it can be reassigned buttons. too bad I dont know how lol
[15:23:43] <pink_vampire> http://www.amazon.com/gp/product/B00BV9N3M6/ref=pd_lpo_sbs_dp_ss_2?pf_rd_p=1944687462&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B0036VO67I&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1ZRKYYP1XE9SBN15RF4Z
[15:23:46] <XXCoder> its cheaper to just buy full keyboard chips/
[15:24:00] <XXCoder> theres billions made and chip probably not even a dollar
[15:24:11] <_methods> hey do whatever you want i was just throwin that idea out there for you
[15:24:22] <_methods> it's cheap, simple and it just works
[15:24:25] <XXCoder> indeed
[15:24:32] <pink_vampire> I
[15:24:50] <pink_vampire> I need to use a pen with the mini keyboard..
[15:26:07] <XXCoder> _methods: http://www.extremetech.com/extreme/56538-hack-your-keyboard
[15:27:32] <pink_vampire> XXCoder: I did it as a kid
[15:28:13] <pink_vampire> arduino pro micro is better.
[15:28:39] <pink_vampire> you can connect rotory encoder to it and make it much smarter.
[15:28:46] <XXCoder> lol wish I was doing that stuff as I was growing up
[15:28:53] <jdh> what do you do with an arduino and lcnc?
[15:28:58] <XXCoder> unfortunately was very poor
[15:29:31] <pink_vampire> I'm poor now
[15:29:39] <XXCoder> lol not that poor
[15:29:48] <XXCoder> I mean live at camp for over year poor
[15:30:12] <XXCoder> I mean food or electricity poor
[15:30:47] <XXCoder> compared to that I'm quite rich. I'm not compared to most people but yeah
[15:31:04] <pink_vampire> i don't have any clothes
[15:31:25] <djdelorie> that would explain why we only see your hands in the photos :-)
[15:31:47] <Deejay> haha :D
[15:32:05] <djdelorie> gives new meaning to "chip control" too
[15:32:14] <pink_vampire> djdelorie: you need to look more carefully
[15:32:56] <pink_vampire> I mean I have clothes but I need a few more
[15:33:11] <pink_vampire> also shoes.
[15:33:23] <gregcnc> a woman the "needs" more clothing or shoes, can't be
[15:33:59] <pink_vampire> gregcnc: what do you mean??
[15:34:05] * djdelorie always needs more t-shirts. 100 just isn't enough...
[15:34:11] <frysteev> hello all, looking for some help with a mesa servo setup, not new to linuxcnc, just new to the world of servos, and pretty lost....
[15:34:28] <djdelorie> old-style servos or "stepper killer" servos?
[15:34:55] <frysteev> mid 90's analog servos
[15:34:58] <varesa> can I define subroutines in the MDI tab?
[15:35:01] <XXCoder> okay gonna add armor to my steppers if killer servos exist ;)
[15:35:21] <XXCoder> brb
[15:35:26] <pink_vampire> lol
[15:35:28] <gregcnc> what kind of servo amp?
[15:35:38] <djdelorie> i.e. are you using a servo controller with an external feedback loop (through the mesa boards) or a built-in one (like clearpath servos) that acts like a stepper
[15:36:06] <djdelorie> also, what kind of feedback do you have (encoder, dro, etc)
[15:36:17] <varesa> I tried o100 subroutine\n G0 ...\n G0 ...\n o100 endsub\n o100 call and nothing happened
[15:36:32] <frysteev> Mesa 7i77. with servo dynamics SDFP 1525 drives
[15:36:49] <frysteev> doing a retrofit on a Hurco Hawk 5M
[15:37:50] <frysteev> servo amps, have a tach feedmach from ther servo, and there is encoders on the motor
[15:38:13] <gregcnc> what's the hangup?
[15:38:33] <frysteev> where to start with PID.....
[15:39:05] <frysteev> i managed to get the encoder scale setup corrently
[15:44:06] <gregcnc> http://www.ni.com/product-documentation/2923/en/ this helps understand what's going on
[15:46:42] <gregcnc> http://gnipsel.com/linuxcnc/tuning/servo.html this is a basic process
[15:47:38] <frysteev> ive read the second one, just reading the first link. just kind of overwhelmed
[15:48:05] <floppydisk-ph> Look at John thornton s instructions on gnipsel. He talks about tuning a west amp servo, which is the precursor to servo dynamics. Google him...
[15:48:56] <floppydisk-ph> Some of the servo dynamics look eriely similar, I think.
[15:49:25] <floppydisk-ph> Oh, greg beat me to it thanks
[15:51:34] <frysteev> is there a starting point for PID values, or is it just a guess at first...
[15:51:51] <gregcnc> anything, but like the NI paper says start low
[15:52:55] <pink_vampire> why the EDM make super bright sparks??
[15:53:18] <XXCoder> magic
[15:53:32] <XXCoder> probably it takes much energy to seperate
[15:53:36] <pink_vampire> I'm using about 100A 12V DC
[15:53:50] <gregcnc> I pushed the values too high because I didn't understand what i was seeing and you don't want to do that
[15:54:12] <pink_vampire> it's look like a camera flash
[15:54:13] <XXCoder> ah nm lol
[15:54:28] <pink_vampire> like someone welding inside the house
[15:54:53] <gregcnc> turn on the eurodance and break out the drinks?
[15:55:24] <pink_vampire> and the water get hot
[15:56:12] <gregcnc> EDM uses a lot of power
[15:57:12] <XXCoder> zeeshan|2: just watched your video. was that still rough cut?
[15:57:49] <pink_vampire> and the tip of the graphite gone very fast
[15:58:12] <pink_vampire> maybe 100A it's a bit too much?
[15:58:37] <neckro23> that's a lotta amps
[15:59:07] <pink_vampire> I can go also 200A 6V
[15:59:20] <pink_vampire> or 50A 24V
[16:00:03] <pink_vampire> WOWWWWWW
[16:00:17] <pink_vampire> on 200A 6V it's soooo bright!!
[16:00:20] <pink_vampire> wowww
[16:00:24] <XXCoder> whats you doing?
[16:00:35] <SpeedEvil> Do not look at it
[16:00:58] <pink_vampire> SpeedEvil: I know
[16:02:22] <pink_vampire> even under water it's soo bright and the electrode 10mm diameter get a bit hot, and the aluminum that I'm trying to EDM just melt inside the water.
[16:02:29] <neckro23> didn't know EDM was a thing actually, obviously I have a lot to learn about CNC junk
[16:03:22] <pink_vampire> arc furnace it's also cool, but I want EDM!!
[16:07:25] <AndChat|128225> Why is my preempt kernel is stuck at 3.18 or whatever it was when it installed what repository do I connect to to get it up to date
[16:10:54] <XXCoder> great video on history of coding renders. https://www.youtube.com/watch?v=Qx_AmlZxzVk
[16:11:14] <SpeedEvil> pink_vampire: that's not what EDM is
[16:11:35] <pink_vampire> I know
[16:12:12] <pink_vampire> I think I need to bump up the voltage and lower the amps and give it some time.
[16:16:54] <AndChat|128225> Sorry I mean 3.16 RT preempt kernel is there anyway to get this updated to the newest version I think it's supposed to be 4. something
[16:19:54] <Deejay> gn8
[16:20:54] <XXCoder> laters
[17:00:14] <pink_vampire> 200A EDM without water = 4th of july!
[17:00:53] <Jymmm> Pfff, the beach has plenty, use that
[17:13:05] <AndChat|128225> Guys is anyone running the rt-preempt kernel and having success with installing teamviewer?
[17:16:54] <enleth> laser cutter works
[17:17:43] <enleth> didn't expect it to, in fact
[17:20:07] <SpeedEvil> enleth: yay
[17:20:11] <SpeedEvil> enleth: Watt?
[17:21:23] <enleth> 40
[17:22:32] <SpeedEvil> I'm pondering a 6W dildo laser.
[17:22:37] <SpeedEvil> diode
[17:27:51] <alex4nder> haha
[17:32:29] <kengu> what ever turns you on
[17:33:55] <_methods> pew pew
[18:26:36] <Valen> shots fired
[18:26:57] <Valen> I do wonder about sticking a laser on my mill head
[18:32:01] <malcom2073> Mills move pretty slow
[18:32:17] <malcom2073> A guy I know stuck a 2W diode laser on his though, did some plastic engraving
[18:37:47] <enleth> fires shat
[18:46:03] <Valen> Going to be moving from 2.4 to 2.7 today with a mesa setup, anything in paticular I should know?
[19:25:38] <AndChat|128225> Guys anyone able to speak to me about the rt-preempt kernel?
[19:27:57] <AndChat|128225> I have uname -a gives me this: Linux cnc 3.18.13-rt10mah+ installed, but a friend is running debian x64 4.1.0-0.bpo.1-rt-amd64 rt-preempt
[19:28:46] <AndChat|128225> I am trying to figure out why I'm not getting new kernel updates
[19:29:33] <CaptHindsight> AndChat|128225: what did you install Linuxcnc from?
[19:30:04] <CaptHindsight> ubuntu ISO, debian ISO, what version?
[19:31:27] <AndChat|128225> Both of us Debian 8.4 vanilla then the linuxcnc.ISO to get the rt-preempt kernel
[19:31:54] <CaptHindsight> did you use an ISO from http://www.linuxcnc.org? or istall Debian and then add Linuxcnc later yourself?
[19:32:42] <AndChat|128225> Installed Debian vanilla then followed the link on the forums from linuxcnc for the linuxcnc.iso
[19:33:12] <CaptHindsight> you might not have the repos installed from linuxcnc
[19:34:09] <CaptHindsight> if you do your own install then you have to know what you are doing vs using a Linuxcnc ISO
[19:36:14] <CaptHindsight> AndChat|128225: are you using Wheezy or Precise?
[19:36:23] <CaptHindsight> http://linuxcnc.org/docs/2.7/html/getting-started/getting-linuxcnc.html#_installing_on_debian_wheezy_with_preempt_rt_kernel
[19:36:56] <CaptHindsight> never mind Precise is Ubuntu
[19:37:12] <AndChat|128225> Jessie
[19:38:30] <CaptHindsight> sorry I don't run Debian and I forget what the cute version names are for
[19:38:37] <AndChat|128225> Jessie
[19:39:17] <hatch789_> capt - sorry changed computers. I'm runnning Debian 8.4 (Jessie) vanilla and then did the install for the rt-preempt kernel from the following link: https://forum.linuxcnc.org/forum/9-installing-linuxcnc/30207-iso-install-of-linuxcnc-on-debian-8-mint-lmde-2?limitstart=0
[19:39:22] <CaptHindsight> is Jessie what they also call testing?
[19:39:42] <hatch789_> this installed linuxcnc 2.7 and gave the preempt kernel to me
[19:40:04] <hatch789_> so I'm just trying to figure out why my buddy seems to have a higher kernel version and I'm still stuck at 3.18
[19:40:25] <CaptHindsight> you're probably missing repos
[19:40:39] <CaptHindsight> compare yours with his
[19:41:12] <CaptHindsight> https://forum.linuxcnc.org/forum/9-installing-linuxcnc/29764-how-to-install-debian-8-2-jessie-and-linuxcnc2-7
[19:42:49] <PCW> why do you want a higher kernel version?
[19:46:20] <PCW> http://freeby.mesanet.com/4.4.7-rt16.png
[19:46:21] <PCW> http://freeby.mesanet.com/3.18.11-rt7.png
[19:47:15] <PCW> The latest kernels have noticeably worse latency (at least on the hardware I have)
[19:48:38] <CaptHindsight> jepler mentioned that Jessie and the newer kernels were crashing the buildbot
[19:48:47] <CaptHindsight> but that was last fall early winter
[19:48:55] <hatch789_> yeah I was just reading those threads
[19:48:57] <hatch789_> interesting
[19:49:24] <hatch789_> so I am able to run Jessie with the 3.18.13-rt10mah+ kernel just fine
[19:49:34] <hatch789_> well it appears to be fine I have not done latency testing yet
[19:49:45] <CaptHindsight> if it ain't broke :)
[19:49:49] <hatch789_> but I can't get teamviewer installed so that I can get help with my resolvers
[19:50:27] <hatch789_> teamviewer will not work with this kernel ...I tried the 64-bit teamviewer and the 32-bit (with the add-architecture i386 command)
[19:51:03] <PCW> Ive had trouble with the 4.4 kernels ( either crash or bad latency) at least on older hardware
[19:51:05] <PCW> though a had to use a 4.4.7 kernel to run new hardware (Intel N3150)
[19:51:33] <hatch789_> so in those cases are you running the rtai kernel instead of the rt-preempt?
[19:52:11] <PCW> I dont run RTAI anymore, no need
[19:52:45] <hatch789_> because you're using the rt-preempt you mean?
[19:52:54] <PCW> yes
[19:52:54] <hatch789_> sorry if I sound like an idiot. I'm just trying to understand
[19:53:02] <hatch789_> this is all new to me with these kernel choices
[19:53:15] <CaptHindsight> yes, you need real time but not RTAI for most applications
[19:53:38] <CaptHindsight> preempt_rt works with FPGA's quite well
[19:54:17] <hatch789_> ok so I'm cool with rt-preempt 3.18 (what I now have) but I can't get teamviewer installed and without it I can't get some help that I need troubleshooting linuxcnc. My resolvers are not acting right
[19:54:24] <CaptHindsight> RTAI is for when you're using software stepping and a LPT port or an FPGA and you need real low latency for IO
[19:54:39] <PCW> http://freeby.mesanet.com/3.18.11-rt7.png
[19:54:41] <PCW> is low latency
[19:55:52] <CaptHindsight> until the management spyware kicks in :)
[19:56:00] <PCW> (RTAI is low latency on a wider range of hardware but Preempt-RT is very close on same hardware)
[19:56:40] <PCW> well it hasn't kicked in in a year or so
[19:57:06] <hatch789_> ok and the preempt-rt is better (over rtai) because of compatability or something?
[19:57:08] <CaptHindsight> how would you know? :)
[19:57:25] <PCW> well if it has it has not affected latency
[19:57:33] <CaptHindsight> I really wonder how much impact it might have
[19:58:15] <PCW> main advantage of Preempt-RT is more development effort and up-to-date kernels
[19:58:23] <hatch789_> ok gotcha
[19:58:24] <CaptHindsight> would you mind hooking that machine up to the internet and visiting a few website that are frowned on by the guberment? :)
[19:58:37] <PCW> (and ease of building kernels)
[19:58:49] <hatch789_> understood. thank you for the explanation pcw
[19:59:33] <hatch789_> so back to my original issue ...is there anything I can do to get teamviewer installed on my version of the kernel
[19:59:54] <CaptHindsight> plus RTAI is falling back into disarray again, so don't count on it unless you are going to do the work yourself
[20:00:20] <PCW> what problem are you trying to solve with teamviewer?
[20:02:29] <CaptHindsight> https://www.teamviewer.com/en/download/linux/
[20:03:35] <CaptHindsight> you might have to build from source (if they offer it) or be stuck with whatever kernels and libs they used to make the binary package
[20:04:55] <CaptHindsight> http://download.teamviewer.com/download/teamviewer_i386.deb
[20:15:46] <hatch789_> getting this error:
[20:16:11] <hatch789_> ● teamviewerd.service - TeamViewer remote control daemon Loaded: loaded (/etc/systemd/system/teamviewerd.service; enabled) Active: failed (Result: exit-code) since Wed 2016-04-27 17:39:59 EDT; 3min 33s ago Process: 1975 ExecStart=/opt/teamviewer/tv_bin/teamviewerd -d (code=exited, status=203/EXEC) Apr 27 17:39:59 cnc systemd[1975]: Failed at step EXEC spawning /opt/teamviewer/tv_bin/teamviewerd: Exec format error Apr
[20:16:56] <hatch789_> I know I'm running the 32-bit version (i386.deb) but that's because the 64-bit won't work in the newer debians they state it on their site
[20:17:06] <hatch789_> so you have to use the multiarch support to try to install it
[20:17:54] <hatch789_> dpkg --add-architecture i386
[20:28:19] <hatch789> switched computers
[20:54:24] <Duc> Finally got the Techno CNC router home. Was suprised to see they made a custom board to control the servo drives on the table
[22:08:51] <Tom_itx> hah we got to tour the reverse engineering lab tonight
[22:08:58] <Tom_itx> very cool stuff
[22:10:35] <Duc> where at?
[22:10:50] <Tom_itx> all sorts of scanners printers & robotic arms etc
[22:12:00] <Tom_itx> he laser scanned a 3d part into catia while we were in there
[22:13:15] <Tom_itx> they have one they take on site to point cloud damaged spots on composite aircraft so they can build an exact modeled repair patch
[22:13:30] <Tom_itx> layer by layer
[22:13:56] <Tom_itx> then they send the composite patch on site and they are able to make field repairs
[22:15:13] <Tom_itx> they scan the damage after it's been prepped for repair to get the exact cavity for each layer
[22:15:58] <Tom_itx> one is attached to a robotic arm to map it's movements for programming
[22:16:52] <Tom_itx> they were using it to laser scan an entire wing in mere minutes where it would take a human days
[23:07:58] <unfy> *sigh*
[23:21:24] <zeeshan|2> why are you sighing
[23:21:42] <alex4nder> hmm
[23:22:18] <alex4nder> I'm thinking I should mount the gopro on my mill in a fixed position
[23:22:22] <alex4nder> but it's a tough call
[23:22:28] <alex4nder> putting it on the table looks wrong.
[23:22:42] <zeeshan|2> Tom_itx: http://i.imgur.com/t2mT1kt.jpg
[23:23:20] <zeeshan|2> alex4nder: dont do it!
[23:23:26] <zeeshan|2> it should be adjustable!
[23:23:57] <alex4nder> zeeshan|2: yah, I'm just trying to figure out the best place to stick it
[23:24:05] <alex4nder> maybe a corner of the enclosure it's in.
[23:29:37] <alex4nder> hmm, it might make more sense to buy a different camera for streaming
[23:34:41] <unfy> work headaches. and not getting time to 'play' at home
