[00:00:10] <XXCoder> its not show car but get you to work or store whatever
[00:00:33] <tiwake> does not seem very modifiable to me
[00:00:36] <XXCoder> city if I recall is at high 40s. thats better than many freeway mpgs of cars
[00:00:44] <tiwake> what if I want 300hp?
[00:01:43] <tiwake> is the electronic fuel injection system open source?
[00:02:11] <tiwake> oh woah, sub $10k for a new car?
[00:02:13] <XXCoder> meh most cars systems arent open source
[00:02:23] <XXCoder> tiwake: sub 7k, if manual
[00:02:33] <XXCoder> auto $7,600
[00:02:37] <tiwake> nice
[00:02:55] <tiwake> are they making their own engine?
[00:03:04] <XXCoder> thats only thing they make thats new
[00:03:09] <XXCoder> thats why prices so low
[00:03:18] <XXCoder> they use mostly years old proven tech
[00:03:28] <tiwake> yeah, using existing stuff
[00:03:39] <tiwake> thats what I want to do, except for certain parts
[00:03:42] <XXCoder> yeah with all bugs since removed
[00:04:00] <XXCoder> my van is 1996, years after first of its model, there is only 2 recalls
[00:04:06] <tiwake> engines are pretty well developed though, don't need a new engine
[00:04:17] <XXCoder> they had to, to meet mpg promose
[00:04:25] <tiwake> oh, for that, yeah
[00:04:28] <XXCoder> orginial plan was GEO 3 stroke engine
[00:04:33] <tiwake> I don't care about that though
[00:04:34] <XXCoder> but it couldnt reach that high
[00:04:56] <tiwake> 55hp
[00:05:19] <tiwake> variable valve lift? meh
[00:05:20] <XXCoder> I forgot how fast it reaches 60 mph
[00:05:31] <tiwake> ford tried that and its not very reliable
[00:05:55] <tiwake> donno about other companies
[00:06:41] <XXCoder> well if engine has flaws I can always fit geo in it lol
[00:06:44] <tiwake> 12:1 compression... that means top quality fuel only
[00:06:48] <XXCoder> probably need adoptors
[00:07:02] <tiwake> unless they have an injection system for water, alcohol, or something else
[00:07:56] <tiwake> two tanks, one for fuel, one for a fuel injection thing to raise the octane
[00:08:30] <XXCoder> dunno
[00:09:16] <tiwake> 11.5:1 is about as much as you can get away with at 91-92 octane without having detonation issues
[00:09:43] <tiwake> unless they do something really fancy
[00:10:10] <tiwake> I donno, maybe a copper engine block so the heat gets taken away better?
[00:10:13] <XXCoder> hope so, because I just want regular gas :P
[00:11:58] <tiwake> XXCoder: most cars are 9 or 10:1 compression, because regular gas, 11:1 need premium gas 12:1 _might_ work with premium if done carefully
[00:12:28] <tiwake> unless they are trying to...
[00:12:30] <tiwake> ohh'
[00:12:33] <tiwake> thats possible
[00:12:58] <tiwake> XXCoder: I almost wonder if they are trying to cause detonation like diesel trucks, but with gas instead
[00:13:22] <tiwake> "cheap gas only - it has to have detonation to work"
[00:13:23] <XXCoder> heh you know far more than I do :)
[00:13:45] <tiwake> I am curious about that
[00:14:05] <tiwake> I mean, probably not
[00:14:20] <tiwake> "oops, I put premium gas in, now my car won't work"
[00:14:38] <tiwake> hard to start in cold weather
[00:14:40] <tiwake> hmm
[00:14:58] <tiwake> I think diesels operate at something like 20:1?
[00:15:18] <tiwake> but thats with diesel
[00:15:24] <XXCoder> 10000/1
[00:15:36] <XXCoder> impossible to do that lol
[00:15:38] <tiwake> its over 9,000!
[00:16:01] <XXCoder> I guess at insane compression, air itself would ignate
[00:16:15] <XXCoder> or some stupid issues or exploding pisons due to insane pressure
[00:16:22] <tiwake> heh, if you take liquid oxygen and fill a container up and let it turn into gas, it would end up at about 8,000PSI
[00:17:09] <tiwake> 8,000:1
[00:18:10] <XXCoder> heh anyway so 12:1 is high compression for has
[00:18:12] <XXCoder> gas
[00:18:12] <tiwake> waterjets operate at like 80kPSI though... hmm
[00:18:30] <tiwake> yeah, its typically found in really high performance cars
[00:19:44] <tiwake> or cars that try to ink as much performance as possible
[00:20:08] <tiwake> there might be some 4 cylinder cars that do it, 12:1
[00:20:32] <tiwake> XXCoder: "Regular Unleaded Fuel"
[00:20:55] <tiwake> https://www.eliomotors.com/features/#the-4-musts
[00:21:09] <tiwake> 0-60 in 10 seconds
[00:21:31] <XXCoder> 12:1 witg regular
[00:21:43] <tiwake> yeah, I don't understand it
[00:21:58] <XXCoder> awesome thing is #3
[00:22:02] <tiwake> they might either be doing an injection system to raise octane
[00:22:12] <XXCoder> one tire company moved to usa in order to supply elio with tires
[00:22:39] <tiwake> heh, I wonder where
[00:22:42] <tiwake> texas? :D
[00:23:04] <XXCoder> dunno but they usually make em outside usa
[00:23:39] <tiwake> three wheels is what gets me
[00:23:51] <tiwake> I can understand why, make it more aerodynamic
[00:24:07] <XXCoder> half width, half drag
[00:24:12] <XXCoder> more mpg
[00:24:19] <XXCoder> half weight too
[00:24:35] <XXCoder> well bit more than half but much less
[00:24:47] <tiwake> less weight is not good for certain things
[00:24:56] <tiwake> it would be horrible on gravel
[00:25:14] <XXCoder> they test drive on ice and snow, and it drives bit better than regular car
[00:25:39] <tiwake> people who have to drive on loong gravel roads like the old big boat cars
[00:28:21] <tiwake> hmm
[00:29:42] <tiwake> XXCoder: if they readily give out highly detailed wiring diagrams with the car, I might get one
[00:30:08] <XXCoder> they still have 25% bonus on reserving one
[00:30:17] <tiwake> I'm Leary of the variable valve lift though
[00:30:21] <XXCoder> I got it while it was still 50%
[00:30:40] <tiwake> XXCoder: need to plop money down to reserve?
[00:31:18] <XXCoder> yeah there is 8 groups, split into 2, $1000 "all in" gets you reserve number, 750 500 250 not yet but cannot be refunded
[00:31:40] <tiwake> I cant right now
[00:31:41] <XXCoder> then theres "I want in" which is refundable but youre after all those "all in" people
[00:31:44] <tiwake> maybe a year from now
[00:31:47] <tiwake> lol
[00:32:18] <tiwake> moving with no money, owing a bunch of people a bunch of money
[00:32:28] <tiwake> because of ... meh
[00:32:50] <XXCoder> makes sense
[00:32:51] <tiwake> you know what, I don't care that I'm moving to texas with no air conditioning anymore
[00:33:14] <XXCoder> is texas dry enough for swamp cooler?
[00:33:35] <tiwake> the shop I'm going to has a big one set up in the middle of it
[00:34:04] <tiwake> certain parts of texas is really humid
[00:34:12] <tiwake> not so much the area I'm going to
[00:39:53] <XXCoder> cool. washington its just too wrong weather style for that
[00:40:00] <XXCoder> too bad, or I'd build one for heck of it.
[00:40:11] <XXCoder> save money during very hot july and aug
[00:40:45] <tiwake> XXCoder: the tesla car seems pretty cool honestly
[00:41:10] <XXCoder> yeah, but I'm simply not willing to spend that much
[00:41:33] <tiwake> heh yeah
[00:41:48] <tiwake> buy a tesla car and help fund SpaceX
[00:43:51] <tiwake> XXCoder: heh, you can configure it with a spoiler
[00:43:58] <XXCoder> yep
[00:44:04] <XXCoder> look for classic wheel covers
[00:44:11] <XXCoder> its from p2 to p4 days
[00:44:24] <XXCoder> p1 never had any panels and coverings
[00:47:32] <tiwake> $7,800 for my configuration
[00:54:31] <XXCoder> whats you add
[00:55:29] <tiwake> audio, I think trim, something else
[00:55:47] <XXCoder> mines little bit cheaper at 7600 because auto
[00:55:59] <XXCoder> I was tempted with classic tire covers
[00:56:02] <XXCoder> looks cool
[00:56:09] <XXCoder> but mpg loss dunno worth it
[00:56:53] <tiwake> meh
[00:57:01] <tiwake> I don't care about that :P
[00:57:26] <XXCoder> lol I probably wont select it
[00:59:20] <XXCoder> if I recall, EVERYTHING is $12,000 or so
[01:01:17] <XXCoder> oh $14,088
[01:01:43] <XXCoder> funny that even riciously overfeatured elio is still cheaper than most car, new
[01:03:12] <tiwake> thats in the range of a good motor cycle
[01:04:51] <XXCoder> interesting
[01:11:11] <MacGalempsy> why make a car when you could make a flying drone car?
[01:13:40] <tiwake> not useful for pretty much anything I want to do
[01:13:44] <tiwake> erm
[01:14:00] <tiwake> unless I make it to practice shooting it down with my rockets
[02:02:54] <TurBoss> morning
[02:28:50] <Deejay> moin
[03:27:38] <pink_vampire> hii
[03:28:08] <XXCoder> hey
[03:28:12] <XXCoder> hows things
[03:52:47] <Deejay> hi pink :)
[03:54:50] <XXCoder> pink_vampire: hows ya?
[03:55:05] <XXCoder> working on anything new? is your new probe complete?
[04:27:31] <pink_vampire> there is a lot of new stuff
[04:29:27] <XXCoder> nice
[04:29:40] <XXCoder> I'm thinking about buying 3d printer to make some stuff
[05:08:09] <TurBoss> is the hanyang vfd a good choice? its cheap
[05:08:21] <TurBoss> modbus control is a plus
[05:21:51] <TurBoss> i have a omron sydrive but its only 0,55Kw
[05:22:04] <TurBoss> I want 2,2 Kw
[05:22:10] <pink_vampire> XXCoder: why do you want to get a 3 printer??
[05:22:21] <pink_vampire> you have very nice cnc machine
[05:22:37] <XXCoder> I have concept design but it cannot be made by any mill machine
[05:22:43] <XXCoder> so it have to be 3d printed
[05:23:01] <XXCoder> though I'm not getting expensive one, just cheapest okay quality one
[05:23:20] <XXCoder> http://www.aliexpress.com/item/2016-He3D-EI3-reprap-DIY-3d-printer-kit-with-different-models-Aluminium-Extrusion-provide-4-sizes/32679786895.html
[05:23:23] <XXCoder> probably this one
[05:23:30] <XXCoder> no wrong one
[05:23:44] <XXCoder> http://www.aliexpress.com/item/Full-Metal-Frame-3D-Printer-Professional-3d-Color-Printer-with-8GB-SD-Card-LCD-One-Roll/32705186296.html
[05:24:35] <enleth> XXCoder: this is not an "okay quality" printer
[05:24:47] <jthornton> morning
[05:25:03] <XXCoder> you own one?>
[05:25:12] <enleth> XXCoder: trust me, I have several printers in the "hobbyist" price range and even the best ones are a huge PITA
[05:25:23] <enleth> XXCoder: all of them are FDM of course
[05:25:32] <XXCoder> FDM?
[05:25:47] <enleth> Fused Deposition Modeling, which is the proper term for the fiilament-based printers
[05:26:38] <enleth> every hobbyist FDM I've seen so far will make trouble, require constant fiddling and crap out on you in the worst possible moment
[05:28:10] <enleth> don't get me wrong, even expensive FDM printers *are* still cheaper than cheap SLA or SLS so they do have their place, just don't expect one to actually be hassle-free
[05:28:43] <enleth> if the seller is claiming easy and reliable operation, it's a lie
[05:30:55] <XXCoder> yeah I expected so
[05:30:57] <enleth> a whole hackerspace worth of people with enough skills to build one is barely enough to maintain those in working condition even though they're not particularly heavily used
[05:31:04] <XXCoder> "cheap" comes with price
[05:31:29] <enleth> like, sometimes people just give up and do other things, and the printer just waits there until someone really needs one working
[05:31:48] <enleth> then it's a day's worth of cursing and fiddling to get it to print again
[05:31:54] <enleth> for a week or so
[05:32:19] <XXCoder> dang
[05:32:31] <enleth> so far I think Aleph Objects AO-100 was the most reliable one we had
[05:32:47] <enleth> or AO-101, I can never remember if that was 100 or 101
[05:33:02] <enleth> a nice solid machine, for a reprap-style FDM printer
[05:33:17] <enleth> but it still does give you a fair share of trouble
[05:33:43] <enleth> I have yet to see a highly reliable FDM extruder
[05:39:17] <jthornton> dang network is flaky this morning
[05:39:30] <XXCoder> yummy flaky
[05:39:51] <XXCoder> enleth: yeah I am not expecting perfect machine just work well enough
[05:59:07] <enleth> XXCoder: oh, and the AO printers run from $1250 to $2500
[05:59:17] <XXCoder> cheap for companies
[06:00:02] <enleth> all that gives you is a very solid cartesian robot and control electronics that actually won't crap out on you, but the extruder is still going to give you pain and suffering
[06:00:24] <XXCoder> honestly im slightly tempted to just use my cnc router
[06:00:32] <XXCoder> just add extuder head to it
[06:00:36] <XXCoder> no heat bed though
[06:00:46] <enleth> you could put a heat bed on it
[06:00:52] <enleth> they can be bought separately
[06:00:56] <XXCoder> indeed
[06:01:10] <enleth> but the problem with using heavier machines for printing is infill speed
[06:01:20] <XXCoder> but there is limited range before its cheaper to just buy machine whole
[06:01:28] <XXCoder> hm yeah
[06:01:39] <enleth> try actually running some printer G-code with a spring-loaded pen attached
[06:01:56] <XXCoder> my machine can do 200 m/s
[06:02:02] <enleth> linear
[06:02:15] <XXCoder> its low speed range it has some issues with resorecnces
[06:02:19] <enleth> can it keep up in a wavy diagonal pattern or 3mm hexagons?
[06:02:34] <XXCoder> dunno as I still need to fix it a little
[06:02:52] <enleth> look up 3D printing infill patterns and watch some videos of a printer doing an infill
[06:02:57] <enleth> you'll see what I
[06:03:03] <enleth> what I'm talking about
[06:03:04] <XXCoder> slightly tempted to just buy whole cnc router kit rather than bastard adopted together I have now
[06:03:10] <XXCoder> yeah I recall
[06:03:17] <enleth> a heavy machine will shake itself apart trying to do that
[06:03:25] <XXCoder> I have photographic memory that SOMETIMES work
[06:03:27] <XXCoder> sucks
[06:03:42] <enleth> and still essentially perform a mechanical low-pass filter on the path
[06:04:03] <XXCoder> yeah I think its cheaper to just get whole printer
[06:04:29] <XXCoder> I have still yet to create adoptor to connect 52mm spindle to my machine lol
[06:04:41] <XXCoder> I run $5 million cell now so i cant run my project now
[06:04:52] <XXCoder> I cant walk too far away from it
[06:06:28] <XXCoder> it does suck, I hope to evenually return to machines I usually run at work
[06:06:36] <XXCoder> though its nice other ways too
[06:17:15] <jthornton> dang windoze computer is rebooting on its own now :(
[06:20:15] <archivist> the Microsoft advantage
[06:21:05] <XXCoder> its just very proactively refreshing itself
[06:23:05] <renesis> guys are you going to watch german gp?
[06:24:40] <XXCoder> as i dont even know what gp is, likely no :)
[06:25:24] <renesis> a grand prix
[06:25:43] <renesis> like, pre, not pricks, because frenchies
[06:29:57] <XXCoder> ok
[06:32:02] <renesis> racecars!
[06:50:14] <enleth> renesis: for some reason your remark reminds me of this sign http://img04.deviantart.net/8794/i/2012/249/a/a/grand_canal_docks__dublin_by_celticsurrealist-d5dqt7n.jpg getting defaced into this: http://img2.thejournal.ie/inline/2220229/original/?width=500&version=2220229
[06:50:47] <XXCoder> thats p[retty effecient
[06:51:02] <XXCoder> bump off d and move c
[06:52:13] <enleth> XXCoder: they actually painted C over and D partially
[06:52:51] <XXCoder> they painted D over after switch
[06:53:10] <XXCoder> in least thats what it seems
[06:53:36] <XXCoder> interesting
[06:53:42] <enleth> no, this photo is clearer on that: http://m0.her.ie/wp-content/uploads/2015/07/16210210/Grand-anal-cocks-.png
[06:53:54] <XXCoder> yeah
[06:53:54] <enleth> they painted off the corners and middle section on D
[06:54:00] <enleth> and just blacked out the C
[06:54:09] <XXCoder> I saw corners on that c and figured that
[06:54:39] <enleth> also, the first several google results for "grand canal docs sign" is this
[06:54:43] <enleth> *docks
[07:31:08] <jthornton> time to check my mud hole
[07:31:21] <XXCoder> yummy
[07:45:20] <JT-Shop> looks like I'll be digging a stump out after breakfast
[07:54:40] <JT-Shop> MacGalempsy: the latest motherboards I've purchased is Gigabyte J1900N-DV3 and Gigabyte H81M-S2H GSM and both have reasonable latency
[07:55:14] <JT-Shop> the J1900 works well with ethernet cards with two Ethernet ports built in
[07:56:07] <JT-Shop> the H81M has lower latency and a serial port so good if you need to control a VFD
[07:56:27] <JT-Shop> actually the J1900 also has a serial port
[07:57:56] <JT-Shop> pcw_home: is a walking database for motherboards and I only know what I've learned from him
[08:02:39] <JT-Shop> yea 2.7.6 is out
[08:06:40] <Deejay> hmm, I should renew my cnc computer somewhen... its still old ubuntu system (10.04?)
[08:07:18] <archivist> that new!
[08:07:21] <Deejay> when checking for updates, the ubuntu app hangs
[08:07:46] <Deejay> not sure, perhaps its 8.04?
[08:07:54] <Deejay> from 2009 or so
[08:08:01] <Deejay> when i setup the stuff
[08:08:31] <Deejay> hopefully there are a lot of nice new features ;)
[08:08:54] <archivist> I know 10.04 update hangs, the older 8 is ok
[08:09:16] <Deejay> ah, ok, then i have 10.04 ;)
[08:09:43] <Deejay> it says "hey, diz is no longer supported, please upgrade", but when i click ok, it hangs
[08:09:56] <Deejay> but the system itself works fine
[08:10:36] <archivist> a pathetic bug considering they have discontinued support so that hang will never be fixed
[08:10:47] <Deejay> perhaps i should install a SSD by that occasion
[08:11:27] <Deejay> perhaps one should just disable the update check and its fine ;)
[08:11:30] <JT-Shop> Deejay: I still have 3 CNC machines running 10.04
[08:11:53] <Loetmichel> Deejay: my home CNC still runs on 10.04 either
[08:11:55] <archivist> I have one on 8 and two on 10
[08:12:05] <JT-Shop> I made some changes that makes 10 update ok now
[08:12:07] <Deejay> yeah, it runs fine, but its old ;)
[08:12:19] <Loetmichel> should upgrade it some time. bit they say "never change a running system"
[08:12:20] <Loetmichel> ;)
[08:12:37] <Deejay> thats it, Loetmichel :)
[08:13:49] <ktchk> I am not going to change that, 10.04 works with remastersys and heekscnc 0.18
[08:13:59] <JT-Shop> http://paste.ubuntu.com/21630521/
[08:14:35] <Deejay> JT, that fixes the update bug?
[08:14:46] <Deejay> just replace the deb entries?
[08:16:12] <Deejay> will have a look at it in a few minutes
[08:16:24] <JT-Shop> yea
[08:16:53] <JT-Shop> your morning song https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwir_b7R3p3OAhUGQJoKHb1hBB0QyCkIITAA&url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3Dkx0Xd0I7Y8o&usg=AFQjCNFh_KqkxhYSOmZM72RKrYVjv8Lt_Q
[08:17:05] <JT-Shop> stupid google
[08:17:11] <JT-Shop> https://www.youtube.com/watch?v=kx0Xd0I7Y8o
[08:56:41] <Tom_itx> JT-Shop, what changes did you make to 10.04 to fix updates?
[08:58:50] <Tom_itx> i don't feel so bad running Ubungu 10.04 as win10 just barely is out :D
[08:59:56] * Tom_itx turns the light on to see the kbd
[09:27:12] <MacGalempsy> JT-Shop: thanks for the info. that first board looks pretty attractive and small. not sure there is enough room inside the control box, but it might fit up and out of the way.
[09:40:05] <plpower> hi widy in germany here
[09:40:58] <Deejay> tnx JT-Shop, i am now running 2.7.5.
[09:41:25] <Deejay> 2.7.6 seems not to be in deb-linuxcnc.org-stuff atm
[09:41:32] <Deejay> (buildbot has it)
[09:41:39] <plpower> is there all fixes on 2.7.5 as G61 dident work on the 2.7.4
[09:41:52] <Deejay> having 2.7.6-sim running on my normal pc
[09:42:04] <plpower> i did update to 12.04 euns cool so far
[09:42:28] <plpower> dont like th look of the wheez
[09:42:48] <plpower> and all the nice cad cam work fine on 12.04 as well
[09:43:09] <plpower> even the apt version of heeks is a real good thing
[09:43:17] <plpower> thanks to the ppa
[09:44:23] <plpower> it does not overright the ho,meemade posts now so only change is mashines.txt to bring up all the cool posts
[09:45:15] <plpower> JT-Shop: most vfd are able to take analog
[09:45:30] <plpower> and easy 1USD elek from pwm parport to vfd
[09:45:57] <plpower> thrue a Nand
[09:46:00] <plpower> 4011
[09:46:38] <plpower> there is a sample on wiki
[09:49:22] <plpower> Deejay: are you effected by thunderstorms today
[09:50:14] <Deejay> would be nice if we get some rain here :/
[09:51:04] <plpower> here ZW there are 60K people so no rain woudt be good
[09:53:06] <JT-Shop> Tom_itx:
[09:53:07] <JT-Shop> <JT-Shop> http://paste.ubuntu.com/21630521/
[09:53:55] <JT-Shop> Deejay: just don't hit a limit switch until 2.7.6 hits the street
[09:54:39] <plpower> 2.6.12 still the choice of the day
[09:54:47] <JT-Shop> plpower: many can be controled via modbus over serial too
[09:54:59] <plpower> agree
[09:55:39] <plpower> but why using extra port
[09:56:11] <plpower> parameters oly set one time then its a speed pnly
[09:58:19] <plpower> Maybe sunday not a good day to ask BUT where to start on tread lathe mashine building
[09:58:43] <plpower> lathe is easy but tread needs to be rpm sync
[09:59:06] <plpower> lower then 1.5Kw
[09:59:56] <plpower> can a parport IN take a encoder
[10:02:38] <jdh> if it isn't very fast
[10:05:17] <JT-Shop> plpower: with modbus you can go fwd/rev and set speed... for rigid tapping
[10:05:28] * JT-Shop warms up the hoe
[10:06:31] <plpower> ok more featurers available i see
[10:07:20] <gregcnc> JT-shop get the fluids flowing before getting on
[10:08:23] <gregcnc> do you ever rest?
[10:09:50] <plpower> im at reat start ow pizza spees out of the oven
[10:32:33] <archivist> twin head gas axe make a plasma starter kit ? http://www.ebay.co.uk/itm/Shapecut-CNC-oxy-fuel-cutter-/201634476855
[10:46:41] <Tom_itx> you'd have a spare head :)
[10:47:37] * JT-Shop just finished spraying some yellow stump-be-gone on that big ass white oak stump
[10:52:31] <Loetmichel> JT-Shop: hmmm
[10:52:58] <Loetmichel> i do that with a mix of fertilizer and diesel.
[10:53:16] <JT-Shop> I do it with my John Deere 310A
[10:53:36] <roycroft> i generally pull stumps
[10:53:41] <roycroft> and i don't have a tractor to do that
[10:53:46] <JT-Shop> http://gnipsel.com/images/equipment-shed/big-dig-08.jpg
[10:53:59] <roycroft> i use a combination of chains, come-alongs, and a sawzall to cut roots
[10:54:09] <JT-Shop> ain't no pulling a 2'+ white oak stump out
[10:54:32] <JT-Shop> it's the stump to the right of the crawler
[10:55:06] <JT-Shop> a sawsall would be a big help and not ruin a chainsaw chain
[10:55:27] <roycroft> i've pulled some pretty decent size stumps
[10:55:31] <roycroft> it's a *lot* of work
[10:57:24] <JT-Shop> can you imagine what the settlers had to go through to clear a patch of woods to plant some crops
[10:57:39] <roycroft> they worked really hard for very little reward
[10:59:52] <Loetmichel> i imagine they would have used fire to clear the patches anyway?
[11:00:47] <JT-Shop> they cut the lumber then using mules and axes dug and pulled out the stumps so they could plant
[11:09:31] * JT-Shop thinks a Whihenstephaner is a fitting reward for getting the stump out
[11:09:49] <JT-Shop> opps Weihenstephaner
[11:10:07] <jdh> good idea.
[11:10:49] <JT-Shop> then a nap!
[11:36:38] <Deejay> JT-Shop, is there a problem with the limit-switches in 2.7.5?
[12:26:33] <ctj> Hello. I have a linuxcnc running 2.7 under lucid. Built in Parallel. Connected to Geko 540. It *was* working a couple of years ago. At this point I have all motors locked up. Green power on G540. No fault lights but when I try and step things in Axis nothing happens. No clicks, no movement. What's the next step in debugging this ?
[12:38:03] <JT-Shop> Deejay: if you hit a limit switch in 2.7.5 using Axis the screen locks up, it's fixed in 2.7.6
[12:38:40] <Deejay> oh kay, good to know...
[12:38:48] <JT-Shop> ctj: turn off the charge pump input and see if they move
[12:39:26] <JT-Shop> I only found out about the limit bug because one of my limits was a tiny bit wrong on my plasma
[12:42:01] <gregcnc> is color laser marking on titanium something new? https://www.instagram.com/p/BIh7hB_DfFP/
[12:54:28] <ctjctj> JT-Shop, turn off the charge pump input means what? Where is that done?
[12:54:42] <ctjctj> (same person as ctj)
[13:01:21] <JT-Shop> on the G540 isn't there a way to turn it off?
[13:01:29] <CaptHindsight> gregcnc: http://link.springer.com/article/10.1007/s00339-013-7932-8
[13:02:32] <CaptHindsight> http://adsabs.harvard.edu/abs/2002ApSS..186..150L
[13:05:00] <gregcnc> capthindsight thanks, so it is the oxide layer just like ti anodize
[13:06:17] <CaptHindsight> gregcnc: similar that it develops an oxide, but it's only where the laser has hit it
[13:07:59] <gregcnc> that guy is using a Lit Laser SL-something 30W, I guess it costs 15-20k!
[13:09:08] <CaptHindsight> you can build on from ebay parts for a few $K
[13:09:22] <CaptHindsight> on/one
[13:10:08] <CaptHindsight> I'm putting one together this month actually
[13:11:33] <ctjctj> JT-Shop, Hmm, I'll look into it.
[13:13:28] <JT-Shop> two main problematic areas for a G540 getting the charge pump frequency right and setting the parallel port to epp mode
[13:13:46] <JT-Shop> that's why I never recommend one
[13:17:17] <MacGalempsy> well. I went with the j1900-d3v
[13:17:32] <MacGalempsy> I hope the 4th time is the charm!
[13:18:02] <MacGalempsy> now time to go lay tile... catch yall later!
[13:18:23] <JT-Shop> I'm running LinuxCNC uspace with LinuxMint and the Preempt RT kernel
[13:21:51] <ctjctj> JT-Shop, wouldn't the configuration wizard work regardless if I use the default G540 default settings?
[13:22:45] <JT-Shop> the configuration wizard works, does your parallel port?
[13:23:33] <ctjctj> I'm about to order a new parallel port.
[13:24:31] <ctjctj> JT-Shop, and no, the configuration wizard didn't work. But I'll try it again in a bit.
[13:26:21] <JT-Shop> pci parallel port?
[13:28:46] <JT-Shop> ctjctj: do this google search g540 charge pump site:linuxcnc.org
[13:29:06] <ctjctj> thanks.
[14:55:24] <ctjctj> Is debian Weezy more current than Ubuntu Precise?
[15:45:12] <Roguish> Is there a written simple procedure for rtpreempt on Jessie???? if so, where, please?
[15:45:50] <Roguish> master branch
[15:48:02] <JT-Shop> I have one for LinuxMint
[15:48:15] <JT-Shop> Jessie, hmm which one is that?
[16:22:57] <Kevin`> my x and z axis don't move when commanded below ~40mm/min. y does. any ideas why this would be?
[16:24:17] <pcw_home> Jessie is the current Debian version:
[16:24:18] <pcw_home> wheezy = previous
[16:24:20] <pcw_home> jessie = current
[16:24:21] <pcw_home> stretch = next
[16:25:15] <pcw_home> Kevin`: that can be a sign of marginal timings or voltage levels
[16:25:57] <JT-Shop> anyone need rain, take if from me please
[16:26:26] <JT-Shop> the numbers were easier to keep up with on ubuntu
[16:28:00] <Kevin`> pcw_home: how? wouldn't it always be easier to move slower?
[16:32:00] <Kevin`> pcw_home: I really don't understand this at all, i'm not sure what timings or voltage levels would be involved
[16:36:31] <Kevin`> I increased the minimum on time for the step pulse under the assumption that it's not being turned on hard at a low duty cycle and it seems happier
[16:36:38] <Kevin`> *optocoupler is not
[16:36:59] <Deejay> gn8
[17:08:17] <pcw_home> I've seen this before with optocouplers if driven marginally (low current or short pulses)
[17:08:19] <pcw_home> they stop working at low duty cycles
[17:12:02] <andypugh> This is a nice demo: https://www.youtube.com/watch?v=2UHS883_P60
[17:12:12] <andypugh> The presenter is not hard to look at either
[17:15:09] <Sync> andypugh: who the hell designed all those cray car diagnostic protocols
[17:15:19] <andypugh> Comittees
[17:15:20] <Sync> iso15765 seems to be realatively sane
[17:15:25] <Sync> but iso9141 is just wat
[17:22:19] <Duc> be so much better if she was burnette
[17:23:17] <ctjctj> JT-Shop, thank you. Your pointer got me to the right place. The issue is/was that I moved from a HobbyCNCchopper(?) to the g450 about 2-3 years ago. Ran it for just a test and then other projects took over. I missed that the old config file was for the old controller. I created a config file for the g450 and now things move again.
[17:23:46] <ctjctj> Of course I then managed to munge up my Z axis so I have to re-re-repair it for the forth time.
[17:23:51] <XXCoder> heh its little things that can trip you
[17:25:02] <ctjctj> Seems my CNC router changed its name from "CNCrouter" to "Place to put every piece of junk that comes into my shop without a known place".
[17:25:49] <ctjctj> So the digging out process has been a little slow and I managed to disconnect the Z lead screw trying to manual home the machine. Not hard to fix but it has to be fixed before I can go on.
[17:26:01] <ctjctj> Regardless, JT-Shop ++Cookies!
[17:28:57] <XXCoder> he loves that design. https://www.youtube.com/watch?v=JSDtVUqsXAc
[17:33:09] <JT-Shop> ctjctj: glad you got some progress
[17:36:51] <ctjctj> LinuxCNC is now doing the right thing. It is just a matter of getting my machine to actually work. Maybe even buy some limit/home switches.
[17:44:21] <JT-Shop> LinuxCNC usually does what you tell it to do...
[17:47:44] <XXCoder> the awesome thing and awful thing is computer do what you tell it to do
[17:48:05] <dioz> JT-Shop: i'll buy your cnc plasma table off you
[17:49:16] <JT-Shop> well every thing has a price...
[17:49:41] <andypugh> Anyone want to buy my combo lathe/mill CNC thing?
[17:50:08] <JT-Shop> anyone on your side of the pond I assume
[17:50:25] <andypugh> I could ship, at cost
[17:51:25] <andypugh> I will probbaly eBay it, but I need to wait until I am around for the length of an auction.
[17:57:28] <JT-Shop> doing a lot of traveling?
[17:57:55] <DaViruz> i'm in the UK currently!
[17:58:01] <DaViruz> but i doubt BA would let me check it in.
[17:58:23] <andypugh> Yes, i have an event in the UK, then a wedding in Germany (not my own) and then 2 + 1 + 1 weeks booked working in Turkey
[17:59:02] <andypugh> (the exact dates of the Turkey stuff are yet to be decided)
[17:59:20] * JT-Shop tries to remember the movie about the turkish prison...
[17:59:32] <Roguish> midnight express
[17:59:41] <DaViruz> the drug smuggling guy?
[17:59:43] <DaViruz> that's it
[17:59:54] <JT-Shop> yea that one
[18:00:31] <andypugh> Whenever I hear the word “Coup” in reference to Turkey my mental image is http://c8.alamy.com/comp/A8KDG3/nice-sharp-highly-saturated-portrait-of-a-ginger-highland-cow-typical-A8KDG3.jpg
[18:01:44] <andypugh> That might make no sense if you have never heard a scottish person say “cow”
[18:03:31] <JT-Shop> when I worked in west africa I made friends with a welsh chap, quite interesting to hear him talk in his native language
[18:05:24] <JT-Shop> once a guy from somewhere in Gb with a heavy accent I could not understand what he was asking for, I had to get a Londoner to translate english for me lol
[18:07:42] <andypugh> UK english is a surprisingly varied language
[18:08:02] <JT-Shop> as soon as he translated I could understand what he was asking for
[18:08:15] <andypugh> About the same variation in accents as the US, but without the excuse of distance
[18:08:24] <JT-Shop> lol
[18:08:56] <andypugh> Partly due to the vikings
[18:09:44] <Roguish> that's a good movie for any
[18:09:58] <Roguish> 'youths' who want to go travel the world a bit.
[18:10:09] <andypugh> The Danelaw (https://en.wikipedia.org/wiki/Danelaw ) means that vowel sounds vary a lot
[18:10:16] <JT-Shop> you guys ever see the Sand Pebbles?
[18:10:37] <Roguish> of course. Steve Macqueen
[18:10:40] <JT-Shop> yea the two utes
[18:10:57] <Roguish> how about 'My Cousin Vinny' ?
[18:11:10] <JT-Shop> yep we watch it from time to time
[18:11:26] <JT-Shop> fred quinn's last movie
[18:11:44] <Roguish> making a pizza. realized i don't have any canned pizza sauce. making it up.
[18:11:46] <JT-Shop> you know when you have mud in your tire
[18:11:59] <JT-Shop> canned pizza sauce yuck
[18:12:15] <Roguish> tomatoes and perpercinis from the garden.
[18:12:50] <Roguish> not always yucky. get the $$ kind.
[18:13:07] <JT-Shop> fresh is much better
[18:14:01] <JT-Shop> dang my web page won't load
[18:14:43] <JT-Shop> does gnipsel.com work for you?
[18:14:58] <_methods> nope
[18:15:13] <JT-Shop> crumb
[18:15:36] <JT-Shop> must be a issue with webhost4life.com
[18:15:54] <_methods> someone must have died
[18:16:26] <_methods> only way out of webhost4life
[18:16:52] <JT-Shop> kinda like the hotel California
[18:17:17] <andypugh> https://www.youtube.com/watch?v=FyyT2jmVPAk does a decent job of it, for one person.
[18:17:37] <andypugh> (British accents, that is)
[18:19:31] <Roguish> it's up now
[18:21:06] <JT-Shop> http://www.gnipsel.com/recipes/pizza/pizza-sauce-fresh.html
[18:21:21] <Roguish> you go on now....
[18:21:53] <Roguish> try a food mill for the tomatoes
[18:22:07] <Roguish> smooth as silk
[18:23:06] <JT-Shop> time to wander inside got a porterhouse to cook
[19:15:25] <Tom_itx> mmm what time's dinner?
[21:28:31] <enleth> the Bridgeport retrofit is getting interesting. I'm a little bit stuck on the servo power supply, which I'm going to try to build in-house for a lack of a better idea that doesn't cost a fortune - but before that happens, I found a way out
[21:29:13] <enleth> I ordered an old 48V 62A telecom supply for something like $75 to see if the outputs are isolated or can be made so easily
[21:29:22] <enleth> and there's two more where it came from
[21:30:39] <enleth> so if they are fine with a series connection, I've got 144V at 62A, which is more than enough by a very wide margin
[21:30:50] <enleth> the only problem is that they won't fit in the control enclosure
[21:31:02] <XXCoder> use cnc to cut enclosure
[21:31:38] <enleth> no, I'm not swapping the enclosure, no way
[21:31:48] <enleth> to much wiring to redo from scratch
[21:32:49] <enleth> I'll have to put those 3 in a separate box and carry on with the custom power supply, but at least I won't be blocked by the lack of a suitable power source, even if that's temporary
[21:33:08] <XXCoder> seperate enclosure
[21:33:22] <XXCoder> though i guess theres hard time placing second one
[21:33:36] <enleth> there's nowhere on the mill I can put a box so deep
[21:34:15] <XXCoder> hmm yeah
[21:34:16] <enleth> I mean, without having it getting in the way
[21:35:39] <enleth> those power supplies are rack mounted, 27cm deep, add 10cm at minimum for the wiring on the back
[21:36:00] <enleth> that's going to be one hell of a hunch on the mill, and it will get in the way
