#linuxcnc | Logs for 2015-11-11

[00:06:50] <R2E4> the docs is longer to compile....lol
[00:23:59] <R2E4> haha, compiled 2.6.4 again
[02:08:01] <archivist> justanotherusr, almost any geared hobbing machine could be converted to cnc, it is just a matter of adding the sensing (encoder) and servo drive to the gear spindle or cutter spindle
[02:09:58] <justanotherusr> archivist: any setup you recommend buying?
[02:10:24] <archivist> not really due to price
[02:10:43] <archivist> what do you have and what do you want to spend
[02:11:26] <archivist> remember a 4 or 5 axis mill with added spindle encoder can also hob
[02:12:06] <archivist> I happened to retrofit an old Barber Colman machine
[02:21:27] <Deejay> moin
[02:35:21] <justanotherusr> archivist: Ideally I'd spend at most $2500, but if that can't get me a decent setup then I would be fine with more
[02:49:23] <archivist> do an ebay search for hobbing machine, mostly too expensive or too big
[03:27:17] <justanotherusr> yeah, they are all around $5-50k
[03:27:35] <justanotherusr> archivist: are you saying there isn't a solution for this in my price range?
[03:30:32] <justanotherusr> I'm confused because I think you mentioned that modifying a milling machine was a very cost effective solution
[03:36:08] <archivist> it is, but you need to set the hobbing helix angle some whay
[03:36:19] <archivist> way
[03:37:44] <archivist> either tilt the 4th axis, tilt the head or use a universal mill that has the table rotatable
[03:37:58] <archivist> or use a 5 axis mill
[03:38:39] <archivist> so what do you already have in the way of a mill
[03:49:41] <justanotherusr> nothing, I need a hobb more than a mill, but I would like both
[03:50:58] <justanotherusr> hob
[03:53:10] <archivist> a hob is the cutting tool not the machine,
[03:53:44] <archivist> note the difference between a hob and a gear milling cutter
[03:55:41] <archivist> with a gear milling cutters you only need a normal mill with a rotary
[03:56:21] <archivist> all depends on qty and variation of gears to be made
[03:56:39] <archivist> there is no one right answer
[04:01:35] <archivist> I built a mill first for gear cutting
[04:10:20] <justanotherusr> I thought your hob was on the spindle of the milling machine perpendicular to the rotary
[04:10:57] <justanotherusr> so no, I don't really understand the difference between a hob and a gear milling cutter, I thought a gear milling cutter was a type of hobbing machine
[04:21:54] <archivist> gear milling http://www.archivist.info/cnc/target.php
[04:22:03] <archivist> gear hobbing http://www.collection.archivist.info/showresult.php?prog=1&srcprog=searchv13.php&srcdata=title&Type=PD&Accn_no=9431&subject=27333
[04:22:49] <archivist> milling uses a form tool, hobbing generated the form
[04:22:59] <archivist> generates
[04:23:51] <archivist> for involute the hob has a rack form but produces involute teeth
[04:36:39] <archivist> you also need to think how you make gear blanks and arbours, you need a lathe
[04:48:21] <SpeedEvil> Just make a gear with infinite teeth.
[04:48:37] <SpeedEvil> It's as good as round
[04:54:09] <XXCoder> hey speed arch
[06:27:02] <chuckbob> Help! Anybody have a WJ200 VFD wired up analog to a mesa card?
[06:27:20] <XXCoder> not me
[06:27:28] <chuckbob> lol, or anything similar...
[06:27:48] <XXCoder> I use crappy t6560 lol
[06:28:04] <chuckbob> for some reason, the analog output on my 7i33 card is reading almost 14 volts.. all the time
[06:30:15] <XXCoder> whats it supposed to be for?
[06:30:39] <chuckbob> spindle control, 0-10VDC
[06:32:16] <XXCoder> odd
[06:34:42] <archivist> does it need a current sink?
[06:36:19] <chuckbob> I am able to control the vfd with a battery to the analog inputs
[06:36:36] <chuckbob> a AAA battery gives me almost 50hz...
[06:36:44] <chuckbob> but I am unable to control it from linuxcnc
[06:36:58] <chuckbob> not sure about the current sink
[06:37:21] <XXCoder> sounds like configuration issue to me, but then I never used mesa so dunno
[06:37:29] <archivist> see the mesa docs
[06:37:51] <archivist> may just need a resistor to ground on that pin
[06:38:21] <archivist> I dont have one either
[06:40:29] <chuckbob> no info on it in the docs
[06:40:42] <chuckbob> I had this running before I moved 2 years ago..
[06:40:51] <chuckbob> just a new linuxcnc install, used pncconf...
[06:41:08] <chuckbob> had to rewire everything after the move
[06:41:19] <XXCoder> double check
[06:41:22] <XXCoder> night
[06:41:32] <archivist> I know nothing about pncconf, I use an editor on configs
[06:41:57] <chuckbob> I wish I knew more about the config setup..
[06:42:44] <Tom_itx> http://linuxcnc.org/docs/2.7/html/config/ini-config.html
[06:42:47] <Tom_itx> there you go
[06:43:52] <chuckbob> lol, been there..
[06:43:57] <chuckbob> the rest of the machine is fine..
[06:44:07] <chuckbob> just kind of a new realm for me with the spindle control
[06:45:05] <chuckbob> should be straight forward, no encoder
[06:45:19] <chuckbob> vfd only accepts 0-10vdc
[06:46:52] <Tom_itx> 7i47S has 0-10v out for one
[06:47:08] <Tom_itx> most are -+10v
[06:48:15] <chuckbob> I am using a 7i33 on a 4i65
[06:48:32] <chuckbob> this is a hitachi wj200 vfd
[07:27:28] <_methods> Tom_itx: i'll set up an ftp for that stuff
[07:27:52] <_methods> dropbox will try and d/l everything, forgot about that
[07:28:34] <Tom_itx> one ended up with 255 or more files
[07:28:42] <Tom_itx> one was empty
[07:29:56] <Tom_itx> i'll check later this afternoon
[07:30:38] <_methods> yeah the one was .rar'd
[07:31:14] <Tom_itx> was missing 07
[07:31:52] <chuckbob> Might have to chalk this up as a loss.. not many example out there setting up this spindle control
[07:33:00] <Tom_itx> that control sounds familiar... maybe pete or zee would know
[07:33:59] <chuckbob> I hope so
[09:13:22] <JT-Shop> well the easy conduit is ran
[09:24:03] <anomynous> has anyone played this game? https://www.youtube.com/watch?v=y5gag6Yjenw
[09:27:46] <_methods> yeah it's called defender lol
[09:27:56] <malcom2073> heh
[09:39:03] <CaptHindsight> JT-Shop: conduit! I thought all you country folks got away with just using romex for everything
[09:41:05] <anomynous> _methods, it has defender mode now, i think :)
[09:41:57] <_methods> it would appear so
[09:41:58] <_methods> heh
[09:42:04] <_methods> i loved that game
[09:55:01] <JT-Shop> I'm an x electrician lol
[09:55:32] <JT-Shop> running emt down the wall for outlets and garage door wiring so I can put the osb up
[10:00:28] <anomynous> _methods, it was super fun to play
[10:04:36] <FinboySlick> Look at that little beast: http://www.phoronix.com/scan.php?page=article&item=nvidia-tegra-jtx1&num=1
[10:16:11] <anomynous> https://www.youtube.com/watch?v=TBVPbeArwgI last stage of arcade. I never finished this one ;D Too hard, and then they made it even harder at update.
[10:30:46] <jesseg> Special for today: http://videoflier.com/movies/1447216361553916420912
[10:36:23] <Jymmm> Mornin
[10:45:17] <malcom2073> Hmm, cold air gun
[10:45:19] <malcom2073> that's a nifty concept
[10:47:33] <Jymmm> Yeah, in 1959... https://en.wikipedia.org/wiki/Mr._Freeze
[10:47:50] <malcom2073> hehe
[10:48:06] <Jymmm> just sayin =)
[10:48:10] <malcom2073> Arnold did a very good job, almost salvaged that terrible batman movie
[10:48:48] <Jymmm> no clue, I just rememebred mr freeze when I heard cold air gun is all
[10:49:03] <Jymmm> Well, thought it was Dr Freeze actually
[10:49:36] <Jymmm> but google corrected me =)
[11:04:16] <chuckbob> Well, think I am giving up on this tuning gig... I don't have the theory to do better than this
[11:04:17] <chuckbob> http://i.imgur.com/jMi7B1K.jpg
[11:07:48] <cradek> is that inches or mm?
[11:08:48] <cradek> I have never seen a tuning that benefits from FF0
[11:10:11] <cradek> that looks like a decent tuning even if it's inches
[11:10:51] <chuckbob> inches
[11:11:05] <cradek> I bet you could adjust FF1,FF2 to get rid of that steady state error. Set I=0, then set FF1 so the constant speed part is centered on zero, then set FF2 so the accelerating part is centered on zero, then put I back to where you had it
[11:11:37] <chuckbob> will go give it a shot
[11:11:45] <cradek> it will be very minor tweaks to your FF1,FF2 values
[11:11:59] <cradek> but adjust it without any I gain or you're chasing your tail
[11:16:33] <CaptHindsight> anyone use Amamzon Prime and how has it worked out? Is it worth it?
[11:16:47] <cradek> I had it one year and it wasn't worth it
[11:17:16] <cradek> a lot of stuff is not shipped prime, and the stuff that is costs enough more that it pays for the shipping
[11:17:25] <cradek> it mostly feels like a scam to me
[11:17:54] <CaptHindsight> yeah, it doesn't seem to add up
[11:17:56] <archivist> a bit like a costco membership
[11:17:59] <cradek> there's videos and stuff but I don't care one bit about that stuff
[11:18:32] <CaptHindsight> ah ok, we had Costco and Sam's Club
[11:19:13] <CaptHindsight> I felt cheated by Sam's club when I'd see the same prices at Walmart
[11:19:32] <CaptHindsight> or sometimes even lower at Walmart on sale
[11:20:53] <CaptHindsight> and the 10 cents a gallon savings on gas only work out for me if I fill up nearly every week
[11:24:49] <archivist> be ever so careful if you go for the trial membership, the buggers get your cc number and sign you up regardless
[11:25:32] <SpeedEvil> http://imgur.com/gallery/HO4XTau - on resonance
[11:25:39] <CaptHindsight> yeah, sounds about right, seems you need to only use a gift card these days
[11:26:11] <CaptHindsight> or they sign you up for whatever and make you waste time canceling
[11:27:28] <jdh> I love amazon prime
[11:27:54] <archivist> I prefer my money stays mine
[11:28:45] <jdh> I can order a $2 part in friday night and it is here sunday
[11:29:38] <jdh> I ordered a few $0.90 thrust bearing washers
[11:29:48] <CaptHindsight> jdh: is there an Amazon warehouse near you?
[11:30:10] <jdh> no. there is nothing near me
[11:30:20] <chuckbob> Here is is at 100u/div
[11:30:21] <chuckbob> http://i.imgur.com/8CxAAXg.jpg
[11:33:13] <chuckbob> running a 5khz servo thread now
[11:55:26] <R2E4> IS the 7i76E worth getting instead of the 7i76? Is the ethernet working well?
[11:56:22] <R2E4> Any drawbacks?
[12:12:21] <chuckbob> Here it is now at 50u/div... Think I am going to leave it here
[12:12:22] <chuckbob> http://i.imgur.com/tii2Skb.jpg
[12:15:12] <cradek> much better
[12:15:42] <cradek> ff2 is not quite right, but I is compensating after a little while
[12:15:56] <cradek> but perfectly usable
[12:16:48] <chuckbob> I is set to 0
[12:17:14] <cradek> oh interesting - during this plot?
[12:17:18] <chuckbob> yes
[12:17:29] <chuckbob> the numbers greyed out are my actual settings
[12:17:34] <cradek> cool
[12:17:45] <chuckbob> P 16000, I 0, D 24
[12:17:57] <chuckbob> FF1 27.25, FF2 .1
[12:18:02] <cradek> maybe that's sticktion at the beginning
[12:18:11] <chuckbob> have no idea what I am doing, just a lot of experimenting
[12:18:27] <cradek> looks fine, move on :-)
[12:18:42] <chuckbob> turned off the current loop integrator in the drives and went for the skies
[12:18:55] <chuckbob> torque mode, amc 30a8 drives
[12:20:35] <chuckbob> Thanks for your advice.. managed to work this error down quite a bit
[12:20:51] <cradek> welcome
[12:21:17] <cradek> you might want to put something heavy on the table and see how it works. might find you want your I gain back
[12:21:37] <cpresser> [5~
[12:22:02] <chuckbob> It's a desktop machine, I had a 4" vise on it.. won't be doing anything outlandish on this thing
[12:22:56] <cradek> ah
[12:24:49] <chuckbob> so what do those divisions equate to. Am I to assume that is 50 microinches?
[12:32:21] <FAalbers> hello
[12:36:50] <FAalbers> I bought a 3040T-DJ CNC router http://www.ly-cnc.com/product/CNC_3040T-DJ_Engraving_Machine-en.html and got myself a Dell Optiplex 745 with parallel port for driving it https://www.dell.com/downloads/global/products/optix/en/opti_745techspecs.pdf
[12:37:54] <malcom2073> Hi
[12:39:16] <FAalbers> I first tried to install the software Mach3 that came with it and connected the CNC to the PC using the parallel cable. I could see the Prallel drivers and Mach3 Drivers where installed. When I ran Drivetest.exe it did nothing. It should do the following. https://www.youtube.com/watch?v=-JLfUhmmrhs
[12:39:37] <FAalbers> When I then ran Mach3 software , it bluescreened
[12:39:54] <malcom2073> Heh, well don't run mach3 :) Run linuxcnc!
[12:39:59] <FAalbers> So I decided to install linuxcnc on my machine
[12:40:07] <FAalbers> :)
[12:40:10] <malcom2073> However, bluescreen coudl be indicative of a hardware problem
[12:40:24] <FAalbers> The above was just to let you know how I got here :)
[12:40:31] <malcom2073> Nice
[12:41:04] <FAalbers> I know I still have to read up on the whole getting started manual. but ...
[12:41:28] <FAalbers> Is there a simple way to see if my parallel connection to the CNC actually works ?
[12:41:46] <malcom2073> Yep, once you get linuxcnc installed (or use a livecd), run stepconf
[12:41:50] <malcom2073> it will allow you to test each axis
[12:41:59] <FAalbers> Is there a parallel port trouble shooting tool in the linuxcnc package ?
[12:42:59] <malcom2073> Not so much, stepconf lets you set the pinout of your breakout board, and then test each axis to ensure they wortk
[12:43:17] <archivist> I use a real scope for that, linuxcnc has halscope with it also
[12:43:20] <FAalbers> that might be 6. Stepper Configuration Wizard in the manual I guess ?
[12:44:28] <FAalbers> archivist, I have a Scope and a Logic Analyzer , so that will make it much easier i guess :)
[12:45:39] <FAalbers> archivist, malcom2073 ... what voltage do I expect comming out of the parallel pins ? I never did any parallel port checking before.
[12:46:03] <archivist> it is TTL level basically
[12:46:55] <archivist> but beware some implementations and states are open collector, I have needed external pullups in the past
[12:48:04] <FAalbers> archivist, malcom2073 ... I also found this config ... I guess it will be a good starting point for the stepconf tool :) ... https://github.com/jieter/linuxcnc-config/tree/master/configs/3040t_no-endstops
[12:48:18] <archivist> some breakout boards are also a bit junky and fail to drive the optos in the stepper driver correctly, only a real scope finds that
[12:49:03] <FAalbers> archivist, I should probably then better read signals in the actual CNC box , since it should have the proper pullups if needed.
[12:50:29] <FAalbers> archivist, malcom2073 ... thanks for getting me going. Will test this evening when I get home. Will report later or tomorrow morning. Much appreciated !
[13:34:25] <chuckbob> Getting the hang of it, here is the z-axis tuned up as best as I can get it
[13:34:26] <chuckbob> http://i.imgur.com/SrzH3iz.jpg
[13:34:58] <FAalbers> archivist, Found this , wil test out tonight ... ttp://wiki.linuxcnc.org/cgi-bin/wiki.pl?Parallel_Port_Tester
[13:35:12] <FAalbers> better ... http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Parallel_Port_Tester
[13:37:22] <andypugh> You can try connecting an input pin to an output pin and using the p-port tester.
[13:43:02] <FAalbers> andypugh, is it to pick up pull downs ? Can't I just test the output without connectiong to the input ?
[13:46:28] <DaViruz> i kind of won a http://hobbymaro.puhasoft.hu/Beni/Pict/emco140.jpg on an auction by accident
[13:46:50] <DaViruz> i didn't really expect my bid to hold up
[13:49:48] <archivist> DaViruz, like me and a CMM :)
[13:50:04] <DaViruz> problem is i have nowhare to put it :/
[13:50:22] <DaViruz> unless i manage to get 1500kg machine down the basement stairs, and then a hard turn through a door
[13:50:28] <archivist> chuck the car out the garage
[13:50:55] <archivist> I have moved stuff in parts
[13:50:56] <DaViruz> garage is full of enduro bike stuff, a couple of engines, gearboxes, a gokart..
[13:51:14] <DaViruz> yeah i'm thinking about taking it down there in parts
[13:51:36] <archivist> I had a weeks rapid move around in the garage, the CMM had to have a place to go!
[13:52:32] <DaViruz> there was a small emco VMC in the same auction, i intended to bid on that as well, but i screwed it up :/
[13:52:42] <archivist> contemplated around the house and into the lounge, but not enough space down the side of the house at the moment
[13:53:07] <DaViruz> maybe i'll just rent a new workshop
[13:54:16] <archivist> bikes are on wheels you can move them out the way
[13:55:39] <andypugh> DaViruz: It might be quite small when “undressed"
[13:56:22] <andypugh> Is that a hydraulic power pack next to it?
[13:57:21] <andypugh> FAalbers: You can probably measure the voltage with a multimeter. But don’t be astonished if you can’t. Making a loopback is just an easy way ti run through a few possible parport base addresses.
[13:57:32] <DaViruz> andypugh: im not sure, it's not that specific machine
[13:58:19] <DaViruz> it seems to vary what kind of accessories they have. i've seen hydraulic packs, a big honking transformer (for US use i presume), chip tray, etc
[13:58:52] <andypugh> Woot! I found the same motorcycling suit as I currently wear as new-old-stock in the US on eBay.
[13:59:04] <andypugh> (I thought about buying two, in fact).
[13:59:30] <archivist> hehe intending falling off more?
[13:59:31] <_methods> send me a case of lemon fanta and i'll send you your suits lol
[14:00:12] <andypugh> Mine is not waterproof any more, but is still so much more convenient than the different type I bought to replace it that I have been wearing the leaky one for two years.
[14:00:20] <archivist> I thought that was a USA drink
[14:00:25] <_methods> no way
[14:00:29] <_methods> no lemon fanta here
[14:00:35] <_methods> i wish
[14:00:47] <andypugh> The Alpinestars lets you step in without finding something to sit on, and with your boots on.
[14:01:07] <_methods> no kinder eggs and no lemon fanta
[14:01:07] <DaViruz> i wonder if that funky emcotronic-control is somewhat serviceable or if i need to look at retrofitting straight away
[14:01:11] <archivist> it is a coke brand
[14:01:13] <chuckbob> Do I need a resistor somewhere to use the analog output to a hitachi VFD?
[14:01:20] <DaViruz> http://tovek.se/images/custom/AuctionItem/53693.JPG
[14:01:21] <chuckbob> from a 7i33
[14:01:29] <DaViruz> im not even sure if that window is for a screen
[14:01:36] <andypugh> chuckbob: I don’t think so.
[14:01:56] <andypugh> I run a VFD from a 7i49 with no extra components.
[14:02:17] <archivist> he was getting 14v earlier
[14:02:19] <chuckbob> I measure almost 14 volts from analog out on the 7i33 with no vfd attached, and linuxcnc not even running
[14:02:52] <andypugh> Measuring where?
[14:02:56] <chuckbob> however.. i did notice that if I measure the voltage while touching the leads with my hands, the voltage is what it should be
[14:03:12] <_methods> http://phys.org/news/2015-11-discovery-confinement-state-plasma.html
[14:03:21] <chuckbob> something is definitely missing
[14:03:40] <archivist> the ground/0v connection
[14:03:49] <chuckbob> i had this working last year..
[14:04:23] <archivist> we cannot see your wiring
[14:04:25] <chuckbob> not sure at this point archivist, this was just measuring the analog out +/- leads
[14:05:07] <chuckbob> simple wiring.. the drv and gnd connections from the 7i33 go into the O and L connections on the VFD, respectively
[14:05:31] <andypugh> Is this true of all the outputs?
[14:05:39] <chuckbob> nope
[14:06:02] <andypugh> Do you have a spare output of which this is not true?
[14:06:10] <chuckbob> there are no extra outputs
[14:06:17] <chuckbob> the other 3 axis are used
[14:06:33] <chuckbob> this grounding thing is interesting
[14:06:40] <andypugh> What do they do if temoporarily disconnected?
[14:06:50] <chuckbob> i thought before somebody may have told me last year about using a 330 ohm resistor across something..
[14:07:07] <chuckbob> can't really remember now
[14:07:24] <chuckbob> i'll go out and have a looksie what happens
[14:18:16] <chuckbob> quite strange
[14:18:43] <chuckbob> if i ground myself on the gnd connection, it works as advertised
[14:18:55] <chuckbob> all i have to do is touch it with my bare hand
[14:20:36] <chuckbob> think the jumper bar for the 24v and plc is in the wrong place
[14:24:52] <chuckbob> nope, i am clearly missing something
[14:30:44] <archivist> fingers making a difference means you are missing something
[14:33:18] <FAalbers> andypugh, Sorry , still learning here , what do you mean with 'Making a loopback is just an easy way ti run through a few possible parport base addresses'
[14:45:07] <chuckbob> yup, something is wonky
[14:46:26] <chuckbob> just don't know what it would be, super simple wiring
[14:46:57] <chuckbob> something isn't being pulled to ground when there is no analog output
[14:53:48] * JT-Shop wonders if he should use readyCloud or not
[15:38:15] <aventtini6> hi guys
[15:39:21] <andypugh> FAalbers: Well, you may not know your parallel port base address, though 0x378 seems like a good guess.
[15:40:12] <aventtini6> i have tested today 2 pc
[15:40:18] <andypugh> So, if you end up having to try out a few possibiites, having an input connected to an output. toggling an output on the parport tester and seeing of the input changes, is a good way to be sure.
[15:40:38] <aventtini6> one core2duo 3mhz and one ITX mobile 1.6mhz
[15:41:14] <aventtini6> i got a latency test on the ITX of 6000 and the core2duo 13000
[15:41:51] <aventtini6> the ITX was going from 900 to 5400 max on tests
[15:42:01] <FAalbers> andypugh, Oh ! OK. I might just also use a few LED's with 470 ohm resistors
[15:42:41] <aventtini6> why is so low on the itx the cpu is more inferior to a core2duo
[15:42:59] <FAalbers> andypugh, At work now , can't wait to get home to try all this out
[15:43:21] <FAalbers> Would be a bummer if port is not working
[15:43:46] <andypugh> FAalbers: Or a good excuse to buy something better than a parport
[15:44:15] <FAalbers> andypugh, Well, I could get a better controller , yes
[15:44:16] <andypugh> aventtini6: 13000 is still pretty good.
[15:44:47] <FAalbers> andypugh, The hardware look pretty sturdy for the price though
[15:46:00] <aventtini6> but 3000 is way better
[15:46:27] <aventtini6> the fun part is i have like 20 ITX
[15:46:29] <aventtini6> :))
[15:46:43] <aventtini6> i got a new mikron this week
[15:49:03] <aventtini6> has any one used a ssd
[15:49:03] <aventtini6> ?
[15:49:15] <XXCoder> aventtini6: ssd yeah I do
[15:49:20] <XXCoder> I bought a cheap 16 gb one
[15:49:44] <XXCoder> perfect for linuxcnc
[15:49:57] <aventtini6> :D
[15:50:05] <andypugh> I use the 8 or 4GB DOM ones, that plug straight into an SATA port
[15:50:07] <aventtini6> so i need to get one
[15:50:19] <aventtini6> 16gb is ok
[15:50:24] <aventtini6> not bad
[15:50:29] <XXCoder> you really need just 8 gb
[15:50:40] <aventtini6> i allways use this chep dell pcs
[15:50:40] <andypugh> The SATA power connector is nearly as big as the 8GB drive
[15:51:15] <aventtini6> and today i found some guy that has 21 itx whit mobile intel
[15:51:26] <aventtini6> and decided to make a small thes
[15:51:28] <aventtini6> test
[15:51:42] <aventtini6> and it was way better the a core2duo
[15:52:50] <andypugh> For latency maybe, but it doesn’t hurt to have some CPU horsepower and graphics performance for actually running the software. Latency is not everything.
[15:53:29] <aventtini6> right
[15:54:05] <aventtini6> the actual test is after i run the 7i77
[15:54:24] <aventtini6> i like it because is small
[15:55:09] <aventtini6> i was wanted to ask if there is any shop in EU for HH liniar scales seals
[15:57:52] <andypugh> HH?
[15:59:00] <aventtini6> heindehaim
[16:00:53] <andypugh> Might be worth giving these guys a try, but I just Googled them, I have no experience. http://www.heidenhainencoders.co.uk/repairs-and-servicing
[16:05:19] <andypugh> Some photos: These are useful when you need to drill near a shoulder, or tap near a shoulder. http://www.ebay.co.uk/itm/281776387506 in action https://picasaweb.google.com/lh/photo/P9eXjUQDrZAzSWMBGOZByNMTjNZETYmyPJy0liipFm0?feat=directlink
[16:06:17] <andypugh> 8GB DOM SSD mounted on my next control motherboard: https://picasaweb.google.com/lh/photo/fljp3WINe4Mh2E7cLHyKVdMTjNZETYmyPJy0liipFm0?feat=directlink
[16:07:05] <andypugh> And, finally: I have had quite enough of pattern-making for a while: https://picasaweb.google.com/lh/photo/gQuPtDB0J_ZiqVVDHaf8vtMTjNZETYmyPJy0liipFm0?feat=directlink
[16:07:17] <chuckbob> grrrr.. if i hadn't shaved my head, I would pull my hair out
[16:22:47] <anomynous> is that how you barber
[16:27:16] <andypugh> chuckbob: Have you tried asking PCW? He probably knows how a 7i33 output should work
[16:33:22] <JT-Shop> no more wondering when the rain will start
[16:36:11] <andypugh> I wonder when it will stop?
[16:44:30] <Sync> andypugh: why don't you get something made to fit? :D
[16:56:02] <andypugh> Sync: Where? what?
[16:58:49] <Sync> your leathers
[16:59:27] <andypugh> I should probably get a patch-cable made to fit, the 7i44 is under the 7i84, so needs about a 4” cable, https://picasaweb.google.com/lh/photo/MgJdO_B3gMuyJtf0NLuy5dMTjNZETYmyPJy0liipFm0?feat=directlink
[17:00:49] <andypugh> I don’t wear leathers, I want waterproof. Aerostich make good suits a lot like the Alpinestars, but at £1200 delivered they would need to be a _lot_ better.
[17:02:35] <Deejay> gn8
[17:04:43] <Sync> ah, I don't really care for water proof
[17:04:54] <Sync> 1200 doesn't sound too bad
[17:05:23] <andypugh> That’s £ not $
[17:06:52] <andypugh> All the reviews of similar suits go on about how good the venting is. I don’t want venting, I want waterproof and warm! I can cope with being a bit hot during the summer weeks.
[17:07:52] <Sync> yeah I know it is £
[17:08:27] <andypugh> Also, they suggest that you might want alterations, so it may need to cross the Atlantic a few times.
[17:08:46] <andypugh> They are good, by all accounts, but not good enough…
[17:14:57] <JT-Shop> I like that "summer weeks" like it doesn't last long
[17:16:31] <andypugh> It doesn’t
[17:20:23] <JT-Shop> how long does it take to make a bootable usb stick? I made one before but this is taking quite some time
[17:23:27] <andypugh> dd can take a long time, and there is no feedback
[17:24:10] <andypugh> But sometimes, it just isn’t actually doing anything, and won’t finish
[17:24:26] <andypugh> (I wonder if top would give any clues about whether dd was working? )
[17:24:32] <JT-Shop> the usb drive is blinking, so maybe it is working
[17:24:42] <andypugh> Yeah, that’s a good sign.
[17:24:51] <andypugh> How long has it been?
[17:26:15] <JT-Shop> 45 minutes, I don't see it in top
[17:27:25] <andypugh> I was going to say 30 minutes, 45 would have me wondering too. is it a big or slow stick?
[17:27:35] <JT-Shop> 8GB

[17:29:15] <Sync> andypugh: I just got a few suits for different weather and purposes
[17:29:51] <Tom_itx> 51F but windy as heck
[17:30:15] <JT-Shop> all I have is a pair of cheap FrogToggs lol
[17:31:35] <andypugh> 12C here (53 F) which is just freaky for 11pm in November. The wearther is broken
[17:32:08] <JT-Shop> my nas shows up as nas_E5-1B-6A (AFP) and nas_E5-1B-6A (SMB) what is the difference?
[17:32:36] <andypugh> Apple File Protocol and Samba
[17:33:34] <JT-Shop> I wonder why AFP? gotta look at the system
[17:34:19] <andypugh> It’s probably just sharing on two protocols for convenience. Do you stream any music?
[17:34:47] <JT-Shop> not yet but it has crossed my mind to put all my music in one place
[17:35:52] <JT-Shop> and photos
[17:36:18] <andypugh> Hmm, not due to iPlayer then
[17:36:37] <JT-Shop> no just regular music files
[17:37:13] <JT-Shop> I do have an ipod and can't run itunes on my XP any more apple turned it off lol
[17:37:25] <andypugh> I wonder if Ryanair will let me fly with jars of Stem Ginger if I decant the syrup into <100ml bottles?
[17:38:37] <JT-Shop> what do you make with stem ginger?
[17:41:10] <andypugh> I am not sure. A German friend is a fan of Great British Bake-Off and they apparently use it a lot on there.
[17:41:29] <andypugh> (And it isn’t readily available in Munich, apparently)
[17:41:48] <SpeedEvil> andypugh: you can't get ginger?
[17:41:53] <SpeedEvil> that is - ginger root
[17:42:10] <andypugh> I _grow_ ginger out of my head
[17:42:26] <SpeedEvil> It's very, very cheap in the UK.
[17:42:32] <SpeedEvil> ~4 quid a kilo.
[17:43:06] <SpeedEvil> 3
[17:43:37] <andypugh> I think they can get Ginger, but not the sticky preserved kind
[17:44:08] <FAalbers> I know Ginger
[17:45:11] <JT-Shop> oh dd says it is done... now to test it
[17:46:43] <SpeedEvil> andypugh: it's pretty easy to make yourself
[17:51:38] <zeeshan> howdy
[17:56:37] <zeeshan> i found a stray the other day
[17:56:40] <zeeshan> thinking of naming it
[17:56:48] <zeeshan> tentatively shadow is the name
[17:56:54] <zeeshan> but i thought nakamura would be more appropriate :[
[17:57:00] <zeeshan> fiance wasn't too impressed
[17:57:23] <Tom_itx> did i miss something?
[17:57:35] <zeeshan> not realy :P
[17:57:41] * Tom_itx thought it was gf the other day
[17:57:53] <zeeshan> very observant
[17:57:57] <zeeshan> haha
[17:58:11] <malcom2073> Congrats, we told you to put a ring on that woman when you said she would help you move machines :P
[17:58:22] <zeeshan> ty :D
[17:58:38] <Tom_itx> the end of an era
[17:58:52] <zeeshan> man im excited, i get my japanese manual tomorrow!
[17:59:26] <zeeshan> http://www.kijiji.ca/v-power-tool/hamilton/doall-power-file/1117564615?enableSearchNavigationFlag=true
[17:59:27] <zeeshan> hmm
[18:00:52] <Tom_itx> you gonna learn japanese?
[18:00:56] <zeeshan> no
[18:01:06] <zeeshan> its pretty erasy to understand when there is symbols
[18:01:13] <zeeshan> (this is for the car)
[18:01:23] <Tom_itx> oh
[18:01:49] <jthornton> wow this new motherboard has a latency < 5000
[18:01:58] <zeeshan> which one
[18:02:13] <Tom_itx> cool
[18:04:38] <zeeshan> tom
[18:04:43] <zeeshan> http://recharge.jp/blog/wp-content/uploads/2010/01/p1.jpg
[18:04:49] <zeeshan> for example that
[18:05:02] <zeeshan> you see relays, fan motors, prolly high and low
[18:05:15] <zeeshan> the symbols are for the wire colors which should b e pretty easy to decode
[18:05:27] <zeeshan>
[18:05:27] <zeeshan> is blue
[18:05:37] <zeeshan> 黒 black :)
[18:05:50] <zeeshan> my problem is they're hard to read
[18:05:54] <zeeshan> cause they're so similar :P
[18:12:25] <jthornton> zeeshan, https://forum.linuxcnc.org/forum/18-computer/29147-intel-cpu-on-board-motherboard-suggestion?start=20
[18:14:14] <zeeshan> wow
[18:14:15] <zeeshan> thats a nice combo
[18:14:40] <zeeshan> no serial port though :[
[18:14:55] <jthornton> yea, onboard
[18:15:07] <jthornton> you need a cable and adapter for it
[18:15:09] <zeeshan> need a seperate header cable?
[18:15:09] <zeeshan> ah
[18:15:15] <zeeshan> oh i see it now
[18:15:16] <zeeshan> "com"
[18:15:21] <jthornton> yea
[18:15:38] <zeeshan> this would be way faster than the j1900
[18:16:13] <jthornton> it's so fast compared to the old shit I have...
[18:16:19] <Tom_itx> hah
[18:16:21] <zeeshan> dude trust me i know!
[18:16:22] <zeeshan> lol
[18:16:29] <zeeshan> i use my desktop vs my mil lcomp
[18:16:33] <zeeshan> and i lose even more hair
[18:16:54] <Tom_itx> is this for a machine or desktop?
[18:16:58] <jthornton> I really like the raid NAS I just got
[18:17:04] <jthornton> could be for either
[18:17:12] <zeeshan> whats your machine comp
[18:17:25] <jthornton> going to test my usb stick so a reboot is needed
[18:17:35] <jthornton> which one lol
[18:18:00] <jthornton> brb
[18:22:15] <jthornton> guess I need to try again or put a dvd drive in to load linux mint
[18:23:05] <malcom2073> I've never had luck getting linuxcnc on a usb stick, dunnoy why
[18:23:12] <malcom2073> never had issues with anything else cept it :/
[18:23:17] <malcom2073> liveusb style
[18:23:20] <jthornton> I did it once before and it worked
[18:23:45] <malcom2073> Usually I get it working once, do an upgrade, and then wind up not upgrading again forever cause of it
[18:23:52] <malcom2073> my mill is running ubuntu 8
[18:24:16] <malcom2073> I didn't put it on it, but when I got that machine I tried a couple times to upgrade and gave up :P
[18:24:39] <Tom_itx> _methods around?
[18:25:09] <andypugh> jthornton: Did you manage to persuade the machine to attempt to boot off the stick?
[18:25:09] <Tom_itx> pretty sure i installed from a stick once
[18:25:36] <jthornton> I did but it went to the debian wheezy and didn't boot from the usb
[18:27:13] <jthornton> time to put on my chef hat... see you guys later
[19:12:11] <zeeshan> i tried lifting a breaker at work today for fun
[19:12:15] <zeeshan> couldn't lift it :[
[19:12:28] <zeeshan> something about big breakers make me giggle inside
[19:12:34] <zeeshan> so used to dinky ones
[19:18:40] <PetefromTn_> Evening folks
[19:20:00] <Tom_itx> how's it goin?
[19:20:19] <PetefromTn_> pretty good actualy how are you?
[19:20:36] <Tom_itx> boring task of setting up a hdd
[19:20:49] <PetefromTn_> I gotta do that soon ;)
[19:21:07] <Tom_itx> you could image one
[19:21:09] <Tom_itx> for your lathe
[19:21:45] <PetefromTn_> my wife took me out to Olive garden tonight for a nice meal. They have a veterans day celebration there. I am STUFFED!!
[19:22:01] <Tom_itx> one of our favorite places
[19:22:02] <PetefromTn_> you mean image the one on the Cinci?
[19:22:11] <Tom_itx> you could
[19:22:17] <PetefromTn_> hm
[19:22:21] <Tom_itx> then mod the setup
[19:22:28] <Tom_itx> or start a fresh one
[19:23:54] <PetefromTn_> I honestly like the ubuntu setup and it would be very similar IE both machines have the 5i25/7i77 combo and servo drives
[20:01:21] <shaun414> Hello cncers
[20:06:38] <PetefromTn_> hello
[20:10:14] <shaun414> hello anyone able to help me design a basic vertical pick and place?
[20:10:22] <shaun414> for picking batteries off a wall
[20:10:29] <shaun414> they will weigh 2kg though
[20:51:43] <Tom_itx> _methods?
[21:35:29] <R2E4> Olive Garden is amazing
[21:35:41] <PetefromTn_> heh
[21:35:52] <PetefromTn_> I definitely like Olive Garden
[21:36:06] <PetefromTn_> and I REALLY appreciated the meal tonight
[21:36:11] <R2E4> Mesa is out of 7i76 cards
[21:36:21] <PetefromTn_> but I actually prefer to go to Carabba's
[21:36:25] <R2E4> They have the 7i76E though
[21:36:42] <R2E4> Sweet tomato's is good also
[21:37:14] <PetefromTn_> I have not tried an ethernet card yet I am sure it would work awesome tho from what I hear of it.
[21:37:47] <R2E4> The 5i25 is processing the steps?
[21:39:47] <PetefromTn_> I think it is paired with a 6i25E or something but I honestly don't remember
[21:40:01] <PetefromTn_> but it would be hardware step generation yes
[21:41:12] <SpeedEvil> http://imgur.com/gallery/LaoU2IU - gas cylinder safety
[21:42:11] <duc> Outback let me down bad tonight. Shitty blooming onion and over done ribeye
[21:42:34] <PetefromTn_> I like the bloomin' onions ;)
[21:43:01] <duc> Same but it was bad
[21:44:38] <PetefromTn_> I'm working on ordering the Z axis ballscrew for the lathe now
[21:44:45] <PetefromTn_> looking at options
[21:45:14] <PetefromTn_> its gotta be at least about a 25mm dia screw and will be ultimately over 1200mm long
[21:45:34] <PetefromTn_> looking for a high lead rate like 5 or 6
[21:50:53] <R2E4> Mesa 7i92, anyone familiar with it? Ethernet fpga card you can connect 7i76 to it. I wonder if that would offload the steps from the CPU....
[21:53:38] <Tom_itx> that's the idea of mesa cards
[21:57:08] <R2E4> Cool,
[21:57:36] <R2E4> How big can you grow the classic ladder?
[21:59:16] <R2E4> You could theoretically put some ethernet fpga cards and bunch of 7i's, not use the motion control and have a big ass PLC....... with a control panel......
[21:59:54] <R2E4> or use a rs422 card and use 7i84's
[22:02:31] <R2E4> 800.00 in hardware, computer, and a buch of programming and you would have a plc that would cost 10's of thousands of dollars in PLC world....
[23:02:58] <Crom> well the K40 laser cutter is now working fine with a Arduino Mega 2560 + RAMP 1.4 + Full graphic LCD controller setup.
[23:05:12] <Crom> Still have to order a replacement 50k ohm ballast resistor. Gonna go with a 100w 2.4Kv 50Kohm resistor this time. Instead of the stock 50w, 1.2kv 50kohm resistor.
[23:07:23] <Crom> could probably go to a 70kohm resistor and be able to get a bit better control of mA through the laser tube. with the 50kohm I'm limited to 60% power thru Turnkey laser entension
[23:14:00] <C_P-Away> Sup.
