[07:26:24] <MattyMatt> popular beastie. 82 bids http://www.ebay.co.uk/itm/XYZ-PROTURN-CNC-MANUAL-LATHE-/321357559300
[07:30:48] <MattyMatt> 2.6t on that palette truck. I'd make an offer for that too
[07:48:36] <skunkworks> was it manual with jog wheels or actual handles on the end of the screw?
[07:51:22] <MattyMatt> that lathe? looks semi-manual to me
[07:51:32] <MattyMatt> aka real handles
[07:52:03] <MattyMatt> the crossslide at least, the handle looks inline with where the screw would be
[08:02:18] <Loetmichel> *gnah* anyone knows how to reduce tha 2 sec lag wiht VLC webcam steraming? this wa its nearly unuseable, the machine will have broken the bit before pressing esc... -> https://www.youtube.com/watch?v=kClMm1yC1Ug
[08:02:44] <Loetmichel> ... and yes, vlc sender and vlc reciver have already all caches to minimum or off that i could finsd
[08:02:46] <Loetmichel> find
[08:09:48] <ries> Loetmichel: aren't not any other streaming solutions? VLC sounds a bit overkill to me? A option could be a security cam with coax?
[08:11:28] <Loetmichel> ries: thats is a bit difficult, having the webcam here and mountet at the machiene ;-)
[08:13:24] <Loetmichel> the pc für linuxcnc is a codualcore Athlon64
[08:14:19] <Loetmichel> AMD Athlon(tm) 64 X2 Dual Core Processor 3800+
[08:14:31] <Loetmichel> that should be sufficient fpr linuxCNC AND the encoding
[08:21:24] <tjtr33> hello, I was surprised to see no user mail this morning, but gmane says... aint no user mail for 24th!
[08:23:23] <skunkworks> same here.. life must have engaged for a while..
[08:35:18] <ries> Loetmichel: I am not a guru on teh subject, but may be due to the real time nature of the kernel VLC get's limited resorces or may be it cannot access some libraries to do iot's compressing.
[08:35:32] <ries> You can try a other compression method, so if that gives anything
[08:46:40] <_methods> http://gizmodo.com/train-derails-at-chicago-airport-makes-it-halfway-up-t-1550226320
[08:59:35] <skunkworks> yikes
[09:35:59] <MattyMatt> ramps like that look better than buffers
[09:57:46] <CaptHindsight> somebody was sleeping at the controls
[09:58:09] <zeeshan> ;]
[09:58:26] <CaptHindsight> the station is going to be down for months
[10:01:33] <CaptHindsight> http://www.chicagotribune.com/news/local/breaking/chi-ohare-train-crash-20140324,0,1750012.story at least the escalator was made well, look how it survived that load
[10:10:11] <humble_sea_bass> red eye flights are the worst
[10:10:20] <humble_sea_bass> i feel like that train
[10:11:29] <CaptHindsight> I prefer them
[10:12:06] <CaptHindsight> .... just not near 3 screaming babies
[10:13:50] <humble_sea_bass> I got home at 1am so it wasnt really really a red eye, but the fact that i was on california time was a problem
[10:14:16] <humble_sea_bass> if it wasn't for stupid monday status meetings I'd have stayed home
[10:15:12] <CaptHindsight> humble_sea_bass: phone conference not possible?
[10:16:33] <humble_sea_bass> my boss loves loves loves to pow-wow for 3 hrs to review every open project and schedule. it is irrational and I've learned to not take off mondays because of it
[10:17:37] <CaptHindsight> heh, no chance of sleeping through it then
[10:18:20] <humble_sea_bass> not in the slightest.
[10:20:21] <miss0r1> Can any of you guys recommend a place where I can purchase cheap and accurate FR4 double sided cobber boards? (The ones I just bought from china varies 6/100mm in thickness across the cobber - NO GOOD!
[10:21:49] <CaptHindsight> miss0r1: where are you located?
[10:22:00] <miss0r1> CaptHindsight, Denmark.
[10:23:31] <humble_sea_bass> I buy from Newark.com
[10:23:41] <humble_sea_bass> i think they have a british counterpart
[10:24:02] <miss0r1> I was thinking somewhere along the lines of some specific ebay store located in europe (no import taxes if i buy within europe)
[10:24:28] <Loetmichel> miss0r1: try some stores taht sell Bungard pcbs
[10:24:35] <Loetmichel> expensive but very good
[10:24:38] <Loetmichel> (german made ;-)
[10:24:56] <miss0r1> Ahh - that smells like quality already - I will look at that. Thank you
[10:25:33] <MattyMatt> Vero is the quality british brand
[10:25:46] <Loetmichel> i use only bungart material
[10:26:14] <Loetmichel> i have pcbs with photo paint on that had 10 years of shelf... worked like fresh from factory
[10:27:28] <humble_sea_bass> you should rotate your stock more often man
[10:27:39] <humble_sea_bass> it is like milk, new ones go in the back
[10:27:44] <MattyMatt> you can't use pre-sensitised boards for that home through-plating process
[10:28:04] <MattyMatt> that looks like fun, although complex and expensive
[10:28:40] <miss0r1> Damnit - it seems I can only find german sellers of bungard pcbs - (My German is more than a little rusty)
[10:28:45] <MattyMatt> I still want to know what happens if you make a pcb out of clear PC
[10:29:23] <humble_sea_bass> you just need to adhere the copper
[10:29:28] <CaptHindsight> I print multilayer PCB's with SLA and SLS (but I'm just showing off)
[10:29:57] <MattyMatt> yeah copper foil is easy to buy
[10:30:04] <CaptHindsight> you could use a clear epoxy
[10:30:16] <humble_sea_bass> west systems will handle this!
[10:30:19] <MattyMatt> or CA or just heat & pressure
[10:30:35] <CaptHindsight> the fiberglass is clear but disperses the light
[10:31:51] <Loetmichel> humble_sea_bass: at home
[10:32:11] <humble_sea_bass> heh
[10:32:49] <CaptHindsight> miss0r1: are you milling the boards to make the traces or chemical etching?
[10:33:01] <miss0r1> CaptHindsight, I am milling
[10:33:03] <archivist> clear saphire pcb, used in microwave work
[10:33:06] <MattyMatt> would thin clear PC stay sufficiently solid at soldering temp?
[10:33:06] <Loetmichel> humble_sea_bass: i havent used etching in a long time now
[10:33:13] <Loetmichel> because i have a cnc mill ;-)
[10:33:23] <Loetmichel> i tend to mill the pcbs now
[10:33:36] <CaptHindsight> transparent aluminum!
[10:33:44] <Loetmichel> https://www.youtube.com/watch?v=jMXxjT4nNxg
[10:33:49] <miss0r1> MattyMatt, I can't seem to find any vero 160x100 double clad boards on ebay.co.uk - Anywhere specific I should look for it?
[10:34:00] <MattyMatt> indium tin oxide. transparent copper!
[10:34:33] <MattyMatt> miss0r1, none I know sorry, only RS
[10:34:49] <CaptHindsight> gold on diamond
[10:34:53] <humble_sea_bass> miss0r1: try element14
[10:35:02] <humble_sea_bass> they are expensive, but they will have it
[10:35:23] <CaptHindsight> is element14 (Newark) world wide now?
[10:35:37] <miss0r1> MattyMatt, I was on the phone with RS earlier, but they didn't know weather their product was precise enough. Now I know - I will just order from them, I've been a customer there for ages.
[10:35:38] <humble_sea_bass> element14 is UK based i think
[10:35:39] <MattyMatt> element14 are farnell
[10:35:47] <humble_sea_bass> newark is their stateside thing
[10:35:57] <humble_sea_bass> FARNELL! that's what i was trying to rmember
[10:36:35] <humble_sea_bass> http://dk.farnell.com/
[10:36:38] <miss0r1> so farnell is also good?
[10:36:59] <humble_sea_bass> they are overpriced, but it is the cost of convenience
[10:38:06] <miss0r1> indeed.
[10:38:38] <MattyMatt> you could take your cheap FR4, and copper plate it with the cathode near the thin end
[10:39:58] <miss0r1> It is not so much a thin end as it looks like the rocky mountain all across the surface
[10:40:15] <humble_sea_bass> hah
[10:40:29] <CaptHindsight> miss0r1: is the copper uneven or the core?
[10:40:30] <humble_sea_bass> so they gave you a crumpled piece of copper
[10:41:55] <miss0r1> CaptHindsight, I am having a hard time determining that. But it seems it is the core
[10:42:04] <CaptHindsight> it's only 2 sided, I'd just use them with the max z depth
[10:42:45] <CaptHindsight> are you sure it's even FR4? That sounds like the really cheap stuff, I forget the name
[10:43:00] <miss0r1> CaptHindsight, The problem is the time I have to spend measuring the entire surface of the board, and determin the top height. Then after than I have to mill it 3 times, or I will break my 0.3mm ballhead
[10:43:09] <CaptHindsight> really low cost and dielectric constant since it has lots of air in it
[10:43:11] <miss0r1> (err... break more of them, that is)
[10:43:35] <MattyMatt> FR2 aka epoxy paper, can be flat if high quality
[10:43:35] <miss0r1> The seller claimed it to be FR4
[10:43:52] <CaptHindsight> have a pic?
[10:44:41] <miss0r1> I can give you the seller link on ebay - I Hve no picture of the board here
[10:44:47] <miss0r1> (I could make one thou)
[10:45:04] <CaptHindsight> just wondering more out of curiosity
[10:45:46] <CaptHindsight> but China + ebay description are terrible
[10:45:54] <miss0r1> http://www.ebay.co.uk/itm/350805001241?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
[10:46:33] <CaptHindsight> nobody check the translations and they just cut and paste whatever into the descriptions
[10:46:47] * MattyMatt just tried to blow the dust off Loetmichel's pcb
[10:47:07] <Loetmichel> MarkusBec: harhar
[10:47:12] <Loetmichel> MattyMatt
[10:47:17] <Loetmichel> did that already
[10:47:30] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14507
[10:47:32] <Loetmichel> result
[10:47:34] <miss0r1> Also - the boards was not individually wrapped, and in only one layer of bubblewrap. (15 boards alltogether) They were pretty mangled upon arraival. :)
[10:47:57] <MattyMatt> I need a cool air jet for milling plastic. I usually babysit it with a hose in my mouth
[10:48:03] <CaptHindsight> that's sad, I'd return them on ebay
[10:48:26] <CaptHindsight> contact the seller
[10:49:26] <miss0r1> CaptHindsight, I did, they tell me I must've dropped them when handeling them. I got pissed - they got pissed. I am now thinking of just giving them to a buddy of mine that etches
[10:49:42] <MattyMatt> I wouldn't bother for something that cost tuppence from china, just chalk it up and use them for something non-critical
[10:50:23] <CaptHindsight> they sounds like they are good BSers
[10:50:39] <CaptHindsight> you must have dropped them :)
[10:51:06] <miss0r1> indeed. And I don't want to sound rich(I am really not) but I can't be too bothered with 20UK pounds, and they know it.
[10:51:10] <CaptHindsight> and torn out the 15 spacers between each board
[10:51:16] <miss0r1> indeed
[10:52:43] <miss0r1> one good thing did come out of this 'adventure'. I was thinking my fixation of the board was to blame, so I did build a vacuum board, with 50 small holes under the surface of a 160x100mm board.
[10:53:21] <Loetmichel> hmm... nothing with my delay problem?
[10:53:46] <Loetmichel> i am the only one that is so insane to "supervize" the mill from the office nearby?
[10:54:28] <gonzo_> dilbert principal, all companies and procutcs are crap. The difference between the number sold and the number not returned through costomer exhasperation or lasyness is called the profit margin
[10:54:55] <MattyMatt> I do that, but it's only a dremel pusher, so I can hear if the tool breaks
[10:55:13] <miss0r1> gonzo_, :D
[10:55:14] <Loetmichel> MattyMatt: thats hat i want to avoid
[10:55:22] <Loetmichel> the tools are expensive ;-)
[10:55:47] <MattyMatt> mine aren't. I get the £10 for 10 sets, probably resharpened
[10:56:07] <Loetmichel> and they cut like crap i suppose?
[10:56:24] <Loetmichel> i mill aluminium with a chinese 6040 so it should be sahr mill bits
[10:57:01] <miss0r1> I am to god-holy lucky; a friend of mine is a tool maker(I don't know if that is the correct term: he makes steel moulds for moulding plastic). When their tools have run for exactly 125mins, they are discharged, even if they are not worn at all - he takes the good ones and give them to me (ALOT!)
[10:57:09] <MattyMatt> I haven't used an expensive one for comparison yet. I'm saving that until I stop breaking them through clumsiness until I've made a few good parts
[10:59:17] <Tom_itx> miss0r1, i could send you some but the shipping would be prohibitive: http://tom-itx.dyndns.org:81/~webpage/etching/Copper2.jpg
[11:02:03] <miss0r1> Tom_itx, Holy! that is some pile you have there!
[11:02:21] <Tom_itx> i have a few full sheets as well
[11:02:35] <miss0r1> I don't even know what size a 'full sheet' is
[11:02:38] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/etching/Copper3.jpg
[11:02:43] <Tom_itx> that's half a sheet
[11:02:53] <Tom_itx> 3 x 4'
[11:02:55] <miss0r1> oh mah' lord!
[11:03:09] <miss0r1> (I don't talk like that in real life...)
[11:03:15] <miss0r1> :)
[11:03:53] <miss0r1> How does one come across that amount? (with no killing going on - I assume you didn't kill anyone?)
[11:04:14] <Tom_itx> local boardhouse closed
[11:04:23] <Tom_itx> bought all their stock
[11:04:33] <Tom_itx> ~3 pickups full
[11:04:34] <miss0r1> Sweet. And that is a good quality?
[11:04:47] <Tom_itx> it's what they ran production with
[11:04:56] <miss0r1> with cnc mills?
[11:05:09] <Tom_itx> no they had huge etch tanks
[11:05:27] <Tom_itx> i use etching as well
[11:05:47] <miss0r1> well, if they etched it, it doesn't really mean that the thickness doesn't vary..
[11:06:10] <Tom_itx> it's not produced for milling...
[11:06:34] <archivist> milling is the wrong way in reality
[11:06:50] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/etching/etch_index.php
[11:06:55] <Tom_itx> there's some results
[11:07:00] <Tom_itx> gotta run...
[11:07:38] <miss0r1> archivist, Indeed - but I like it too much not to.
[11:08:15] <archivist> I have never milled a pcb yet
[11:08:28] <Tom_itx> this is a SOT32-6: http://tom-itx.dyndns.org:81/~webpage/temp/tiny/tinyboard2.jpg
[11:08:37] <Tom_itx> with 3 traces under it
[11:18:52] <rmu> Loetmichel: http://stackoverflow.com/questions/9119106/how-to-reduce-the-delay-vlc-streaming-from-a-web-cam
[11:20:04] <Loetmichel> rmu: thy
[11:28:18] <rmu> Loetmichel: I did not try it myself, but this http://wiki.ubuntuusers.de/MJPG-Streamer should also work
[11:30:05] <CaptHindsight> archivist: people do it because they can but they live without plated through holes, which is why I never bothered
[11:31:47] <Connor> I was going to do it, because I normally just make one-off's.. and I thought it was easier than etching..
[11:31:57] <jdh> me too
[11:31:59] <Connor> Plus, I don't like dealing with the acids..
[11:32:16] <jdh> I haven't done any acid in years
[11:32:52] <Connor> I made the mistake of using high end v-bits that cost like $25-30 each.. instead of the simple single flue ones.. and broke a few and got disenchanted with it.
[11:33:28] <jdh> I made the mistake of trying to use my non-flat cheap router
[11:34:52] <Connor> My router had issues with Z too.. But, I think I solved that by making a fixture... only issue is.. you really have to face it every time you make any sort of adjustment.. and hope you don't knock the router out of alignment while changing the end mill to the v-bit..
[11:35:35] <archivist> bolt it to a bench that holds it straight
[11:35:53] <jdh> I plan on trying it with my 6040 if I ever order one.
[11:35:55] <Connor> router as in the spindle.. not as in the whole thing..
[11:36:06] <CaptHindsight> I rarely have aboard with less than 4 layers, 6-8 is most common
[11:36:34] <Connor> You can't do that DIY..
[11:36:38] <archivist> I only went to 4 layers for one job
[11:37:05] <archivist> fewer layers makes easier to fix
[11:37:32] <jdh> I often only want 1 layer, but 2 would be plenty.
[11:37:52] <CaptHindsight> with SLA + SLA we can have >10 in 0.062", it's actually layerless and more like multiwire
[11:38:20] <Connor> huh?
[11:38:23] <CaptHindsight> SLA + SLS
[11:39:16] <CaptHindsight> 3d printed, similar to a laser printer only using liquids
[12:18:01] <jdh> gwar?
[12:18:05] <jdh> <urk>
[12:21:16] <R2E4_> Does ENA on a 7i77 have a HAL pin?
[12:54:53] <skunkworks_> how do you calculate the acceleration needed for a given circle at a given speed?
[12:56:45] <zeeshan> constant velocity?
[12:56:54] <zeeshan> a = v^2 / radius of circle
[12:57:30] <skunkworks_> heh - just found that ;)
[12:57:35] <IchGuckLive> zeeshan: this is the formal that breaks the tools or and the mashine
[12:57:43] <zeeshan> if its not constant
[12:57:46] <zeeshan> its a bit more complicated
[12:57:58] <zeeshan> you gotta find the tangential and normal components of acceleration
[12:58:10] <zeeshan> IchGuckLive: lol
[13:04:46] <jdh> finished your X on your lathe?
[13:08:48] <zeeshan> jdh no!
[13:08:51] <zeeshan> building steam engine
[13:08:57] <zeeshan> for final capstone still
[13:09:00] <zeeshan> has been taking all my time
[13:09:08] <zeeshan> and at the same time im cleaning up/organizing the garage
[13:09:16] <zeeshan> a dirty garage is quite demotivating
[13:09:21] <zeeshan> you?
[13:09:41] <humble_sea_bass> zeeshan: a particular steam engine, or your own design
[13:09:51] <zeeshan> mostly our own design
[13:09:58] <zeeshan> i mean it's not all original
[13:10:08] <zeeshan> a crankshaft and cross head are fairly common things on steam engines
[13:10:09] <humble_sea_bass> oh is it your senoir design thing?
[13:10:13] <zeeshan> yea
[13:10:28] <zeeshan> mostly me
[13:10:36] <zeeshan> and less of my other group mate
[13:10:44] <zeeshan> have been manufacturing it for the last 2 months
[13:10:46] <humble_sea_bass> kick his ass out
[13:10:49] <zeeshan> can't man
[13:10:53] <zeeshan> we started with 4 people in the group
[13:11:03] <zeeshan> 1 guy dropped out of the course 4 weeks in
[13:11:12] <zeeshan> my other friend got murdered =/
[13:11:18] <zeeshan> half way into the project
[13:11:27] <zeeshan> so its just me and my other group mate
[13:11:29] <humble_sea_bass> cursed steam engine???
[13:11:43] <zeeshan> nah, i think its just a test for both me and him
[13:11:56] <zeeshan> to pull through :D
[13:12:02] <zeeshan> it's starting to shape up pretty nice
[13:12:30] <zeeshan> ill post pics of it when its in good shape :)
[13:12:49] <archivist> must move my steam engine analyser from pascal to js to get it on the web
[13:13:46] <zeeshan> ;D
[13:13:53] <zeeshan> js?
[13:14:10] <zeeshan> archivist: i developed an electronic steam injector
[13:14:21] <zeeshan> that could virtually control the cutoff down to 15%
[13:14:26] <archivist> javascript so it can run in the browser
[13:14:29] <zeeshan> at 4000 rpm
[13:14:34] <zeeshan> but unfrotunately we couldn't build it
[13:14:46] <zeeshan> cause it'd take too long to build the controller
[13:16:33] <skunkworks_> nobody is wondering what the story is of zeeshan's friend?
[13:16:34] <archivist> someone took a diagram from an engine, it always gave a poor diagram, we measured the mechanicals and the auto expansion device, it was bad by design :)
[13:16:39] <zeeshan> skunkworks:
[13:16:39] <zeeshan> lol
[13:16:48] <zeeshan> these guys are harsh!
[13:17:02] <zeeshan> its a simple story
[13:17:06] <zeeshan> he was out with his friends
[13:17:12] <zeeshan> and some scumbags came and shot him to death
[13:17:24] <zeeshan> they say it was an altercation
[13:17:30] <skunkworks_> yikes
[13:17:39] <zeeshan> <- this is why i don't go out to clubs/bars past 12
[13:17:42] <skunkworks_> this is canada?
[13:17:45] <zeeshan> yes
[13:17:48] <skunkworks_> wow
[13:18:10] <humble_sea_bass> where do you live again zeeshan
[13:18:16] <zeeshan> hamilton, ontario, canada
[13:18:21] <zeeshan> i go to mcmaster unviersity
[13:18:25] <zeeshan> it happened near it
[13:19:37] <humble_sea_bass> sounded more like nyc circa 1987 at the height of the crack wave. that sucks
[13:20:14] <zeeshan> honestly i try my best never to get in an arguement with strangers
[13:20:40] <zeeshan> some people don't have anything to lose, they haven't even finished highschool and are selling drugs
[13:20:50] <zeeshan> and are just pretty much scum
[13:21:08] <zeeshan> so it doesn't take much for them to do something that's considered 'wrong' by normal people

[13:21:58] <zeeshan> i think i need to go visit 'mr used'
[13:22:02] <zeeshan> might have some fancy tools there
[13:22:09] <zeeshan> $400 — Fill your car — including the trunk and back seat — with anything it can hold. You must be able to completely close your car doors and trunk.
[13:22:54] <zeeshan> my winterbeater car is a coupe
[13:23:06] <zeeshan> with folding seats, i use it to transport 10 foot long pipe all the time
[13:23:13] <zeeshan> i could fill a lot of stuff! :D
[13:23:56] <archivist> tek scope
[13:24:08] <zeeshan> yes
[13:24:14] <zeeshan> and there is a stainless steel sink i've been looking for
[13:24:16] <zeeshan> utility sink
[13:24:37] <archivist> but that model is 1960's
[13:26:14] <kb8wmc> good day to all
[13:28:21] <IchGuckLive> kb8wmc: HI
[13:29:24] <kb8wmc> IchGuckLive: hello sir
[13:53:01] <archivist> zeeshan, another on on fleabay 271433148782
[13:54:21] <zeeshan> now that's a proper level
[13:54:26] <zeeshan> what do you think it'll reach to price wise?
[13:54:30] <zeeshan> it only got posted today
[13:54:47] <archivist> I have that maker in my watch list
[13:55:04] <zeeshan> you're a master ebayer et?
[13:55:05] <zeeshan> eh?
[13:55:06] <zeeshan> hehe
[13:55:21] <R2E4_> zeeshan: your not in Vancouver!!!
[13:55:23] <archivist> http://www.collection.archivist.info/showresult.php?prog=1&srcprog=searchv13.php&srcdata=title&Type=PD&Accn_no=8283&subject=25070
[13:55:37] <zeeshan> R2E4_: no
[13:55:37] <zeeshan> :D
[13:55:55] <zeeshan> archivist: you don't need that many levels
[13:55:56] <R2E4_> I know, your in TORONTO, but they say eh? out west
[13:56:09] <zeeshan> R2E4_: haha i like saying 'eh'
[13:56:19] <archivist> zeeshan, hence I post them in here for others to get
[13:56:20] <zeeshan> archivist: how much did you pay for that one?
[13:56:32] <archivist> less than 75 :)
[13:56:38] <zeeshan> fak.
[13:56:45] <zeeshan> that is quite cheap.
[13:57:05] <archivist> I got a frame type for 21 plus carriage
[13:57:09] <zeeshan> none of you are bidding on that fleabay level
[13:57:10] <zeeshan> its mine
[13:57:12] <zeeshan> !!!
[13:57:29] <archivist> its a 12" one a bit big
[13:57:53] <zeeshan> wow
[13:57:57] <zeeshan> off of fleabay?
[13:57:58] <archivist> I not the felts are missing from in the box
[13:58:02] <archivist> note
[13:58:11] <zeeshan> that's not a big deal
[13:58:17] <zeeshan> felt can be glued back in :)
[13:58:25] <archivist> yup, you have to watch for years and pounce
[13:58:57] <zeeshan> what does the bottom of the level look like
[13:59:01] <zeeshan> does it have a v groove
[13:59:02] <archivist> iirc mine was ex army stores with a haggle due to rust on its feet
[13:59:03] <zeeshan> or just flat
[13:59:09] <archivist> v
[13:59:12] <zeeshan> awesome
[13:59:27] <archivist> that bum has not shown the feet
[13:59:34] <zeeshan> yea hehe
[13:59:47] <zeeshan> looks proper.
[13:59:51] <archivist> there are possible rust marks in the box
[14:00:56] <archivist> I would worry posting it that far, you should be able to find equivalent over there
[14:04:07] <zeeshan> http://www.ebay.ca/itm/EDA-Level-61R-0-01-200-Engineers-Level-200mm-Long-Sens-0-01mm-m-/360890117575?pt=LH_DefaultDomain_0&hash=item5406ba2dc7
[14:04:09] <zeeshan> what about that
[14:04:30] <zeeshan> i don't see the calibration screw for it
[14:04:49] <zeeshan> bah its only 7.8"
[14:05:37] <archivist> that is similar in length to my smaller one (the one I use most)
[14:06:44] <archivist> greasy fingermarks new!
[14:07:46] <zeeshan> think that would be good enough to level a lathe and mill with?
[14:07:52] <archivist> yes
[14:08:15] <zeeshan> the only thing i don't see is the leveling screw
[14:09:10] <archivist> like my cooke it may be under the label
[14:09:37] <zeeshan> ah it is
[14:09:41] <zeeshan> here is another pic of it from google
[14:09:47] <zeeshan> http://i454.photobucket.com/albums/qq265/shaggy4411/Master%20Precision%20level/level1.jpg

[16:33:38] <skunkworks> seems to..
[16:34:14] * JT-Shop is having network LAN from hell today

[17:16:40] <Deejay> gn8
[17:43:17] <CaptHindsight> http://www.plxtech.com/products/uart/oxpcie952 anyone try out the EPP on these with the Mesa 7i43?
[17:56:49] <CaptHindsight> http://www.indiegogo.com/projects/the-first-all-in-one-3d-printing-technology up to $101, from $100 last week!
[17:57:19] <XXCoder1> its heavy with buzzworfs
[17:57:22] <XXCoder1> "spaceone" lol
[17:58:09] <CaptHindsight> they have some of the best 3D renderings of any campaign so far
[17:58:43] <XXCoder1> tool rack
[17:59:16] <CaptHindsight> I would have chosen Detroit as the location that needs help rebuilding
[18:00:38] <XXCoder1> not interested heh
[18:11:25] <XXCoder1> it may be interesting to some, but it seemed to be really high priced item
[18:11:45] <XXCoder1> maybe if it really was automated tool changing, even switch types - say from cnc to 3dprint
[18:12:33] <CaptHindsight> it's a poor design for FDM or for milling/router
[18:14:26] <CaptHindsight> I'm don;t think they are even going to break even on the time spent for their website or 3d models
[18:14:43] <XXCoder1> if its unsccessful do they get partial fund?
[18:15:01] <CaptHindsight> This campaign will receive all funds raised even if it does not reach its goal.
[18:16:17] <XXCoder1> interesting. ok
[18:16:28] <CaptHindsight> what they should have done was use a duino along with something everyone loves ion #reprap, that way the fanboys would have jumped onto it
[18:16:55] <XXCoder1> rich fanboys
[18:18:12] <CaptHindsight> it's like a cult in there now
[18:18:25] <XXCoder1> yeah theres such thing as toxic fanboys
[18:18:37] <XXCoder1> dont they get it that they are destroying the very thing they loce
[18:18:40] <XXCoder1> love
[18:20:54] <CaptHindsight> hp2200 under $20 http://www.amazon.com/HP-Webcam-HD-2200-BR384AA-ABA/dp/B004UR9P9Q
[18:21:09] <CaptHindsight> going to see how close I can get the lens to focus
[18:23:34] <XXCoder1> cool
[18:23:54] <XXCoder1> I was reading, found interesting ideas on making machine auto zero itself
[18:23:56] <XXCoder1> including z
[18:28:39] <XXCoder1> some machines apparently has spot where they run to and calbrate
[18:29:03] <XXCoder1> buttons, or metal plate
[18:31:46] <PetefromTn_> you mean auto tool zero?
[18:32:12] <XXCoder1> yeah
[18:33:17] <PetefromTn_> I am working on a tool probe for my VMC right now..
[18:34:00] <XXCoder1> I doubt I would ever make auto tool zero. silly when I am just hobbyist
[18:34:27] <PetefromTn_> why my pal Art has it on his RF31 and loves it..
[18:36:03] <XXCoder1> maybe I would do z plate.
[18:36:06] <XXCoder1> easier to zero z
[18:36:11] <XXCoder1> while x and y meh
[18:36:55] <XXCoder1> if I ever build second one, maybe lol
[18:42:14] <CaptHindsight> PetefromTn_: we are working on auto tool zero using a camera
[18:42:32] <XXCoder1> capt how does it work anyway?
[18:42:43] <XXCoder1> does it align with stock edges?
[18:42:47] <XXCoder1> what about z?
[18:42:48] <CaptHindsight> I just need to find a cheap enough camera that works
[18:42:52] <PetefromTn_> seen that before looks cool.
[18:48:21] <CaptHindsight> you find the edges you want and figure out the offset and then home or jog to that position
[18:48:33] <XXCoder1> cool
[18:51:58] <Tom_itx> CaptHindsight, you seen this? http://www.miketreth.mistral.co.uk/centrecam.htm
[18:54:18] <XXCoder1> it looks like tool bit camera
[19:00:00] <CaptHindsight> Tom_itx: I just want to extend http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Axis_Embed_Video to have auto zero
[19:00:41] <CaptHindsight> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Adding_Digital_Zoom_To_Camview-Emc was recently added
[19:01:35] <XXCoder1> so far I see, it automates XY
[19:03:15] <Tom_itx> how do you ensure the camera crosshairs are the tool center?
[19:03:53] <XXCoder1> too bad theres no such thing as "ring camera"
[19:03:56] <CaptHindsight> the camera has to be at a known location
[19:04:13] <CaptHindsight> known offset from the tool center
[19:04:45] <XXCoder1> say, camera with 4 lens that can interplote one picture, plus all 4 pictures would have bit in view. you can calculate angles from it
[19:04:52] <PetefromTn_> Actually you usually just rotate the camera on the spindle and adjust until there is no runout in the video.
[19:05:05] <XXCoder1> if you guys create kickstarter or something just give me enough to get kickass cnc lol
[19:06:40] <CaptHindsight> we already do that and more with a zoom microscope, but most users aren't going to spend $K's on a a camera system
[19:06:55] <XXCoder1> kickstart a cheap version
[19:06:57] <XXCoder1> $100 say
[19:07:01] <CaptHindsight> $15 webcam is another story
[19:07:15] <CaptHindsight> kickstart what?
[19:07:22] <XXCoder1> the ring camera lol
[19:07:34] <CaptHindsight> what's the ring?
[19:07:46] <XXCoder1> I explained it a sec ago
[19:07:49] <XXCoder1> say, camera with 4 lens that can interplote one picture, plus all 4 pictures would have bit in view. you can calculate angles from it
[19:08:54] <CaptHindsight> I'm not a really good mind reader
[19:09:18] <XXCoder1> I'm not sure how I can explain more clearly
[19:09:41] <XXCoder1> ok picture this, a ring attachment on cnc router
[19:09:54] <XXCoder1> it has 4 camera, on - + X as well as Y
[19:10:23] <CaptHindsight> 4x $15 = $60 ok, I follow you
[19:10:28] <XXCoder1> computer then could take picture from all 4, and with 4 different points can calculate where bit point is
[19:11:10] <XXCoder1> it can touch down directly on stock xyz 0 point since it can see from any points of view
[19:12:05] <CaptHindsight> I follow you
[19:12:23] <XXCoder1> as bit of bonus, it would work for every bit. I think
[19:12:32] <XXCoder1> just change bit and hit button
[19:12:46] <CaptHindsight> you're making lots of assumptions
[19:12:51] <XXCoder1> yep, I am
[19:13:28] <CaptHindsight> be sure to let us know how that works out
[19:13:40] <XXCoder1> nah not skilled enough unfortunately
[19:13:54] <XXCoder1> if someone takes this idea and hit it off, all I want is cnc machine lol
[19:18:55] <XXCoder1> wb
[19:35:58] <JT-Shop> say goodnight Gracie
[19:36:41] <andypugh> PetefromTn_: You don't even need to adjust anything really. The centre line of the spindle is the pixel that doesn't move when you wiggle the spindle.
[19:37:37] <XXCoder1> set it to one rpm and let program figure align nonrotating point on 0,0
[19:37:46] <XXCoder1> issue is wire lol
[19:37:57] <JT-Shop> wireless
[19:38:26] <XXCoder1> there ya go heh
[19:39:39] <andypugh> i just had to add 50mm to my Z travel limits.Which involved investigating if I was going to let the balls fall out the screw...
[19:40:19] <andypugh> I need to use the horizontal spindle to machine the edge of the work, as it is too big for the machine otherwise: https://picasaweb.google.com/lh/photo/uoy2UegtJpcl6BD88u_lFdMTjNZETYmyPJy0liipFm0?feat=directlink
[19:42:28] <Tom_itx> not enough travel in X to do it?
[19:42:39] <Tom_itx> err nevermind
[19:42:56] <andypugh> No, not enough daylight under the vertical head
[19:43:34] <andypugh> This is the forst proper CNC job I have done on the machine, I think. Using CAM and suchlike: https://picasaweb.google.com/lh/photo/CSu6UI0YPPadVzIdnFPyFtMTjNZETYmyPJy0liipFm0?feat=directlink
[19:43:58] <XXCoder1> awesome
[19:44:08] <Tom_itx> i was just looking at that one
[19:44:11] <andypugh> I am wondering why the vertical spindle gets so hot, though.
[19:44:27] <andypugh> I wonder if the bearings are wrongly adjusted?
[19:44:42] <Tom_itx> shaft rubbing on something?
[19:44:54] <Tom_itx> or bearings..
[19:45:18] <Tom_itx> did you use cambam for that?
[19:46:13] <andypugh> Yes.
[19:46:17] <Tom_itx> what was your impression of it's 3d capabilities other than the waterline issue?
[19:46:17] <PetefromTn_> Hard to see the parts from the pics..
[19:46:24] <andypugh> It works pretty well when you figure it out.
[19:46:49] <andypugh> The parts are buried in pockets in a fixture (hot-melt glue)
[19:47:11] <Tom_itx> did you mill the backside flat?
[19:47:22] <Tom_itx> or does it have the bend shown in the drawings
[19:47:41] <andypugh> Yes. Though actually I could have put the kink in, with this work plan.
[19:47:44] <XXCoder1> I need to buy cambam so I can do tutorials without running into limits
[19:48:22] <Tom_itx> i downloaded it but haven't used it except to look at a post
[19:48:35] <PetefromTn_> I am liking CamBam so far. It is the best of the low cost bunch that I have tried but it is not without quirks.
[19:48:54] <Tom_itx> what others did you look at?
[19:49:45] <PetefromTn_> So far I have posted probably a little over a dozen programs to the machine and so far everything worked exactly as it was supposed to.
[19:50:28] <andypugh> PetefromTn_: I had to modify the default EMC post to add the G43 to a toolchange.
[19:50:49] <Tom_itx> i think we did that as well but i can't honestly rememeber
[19:50:52] <PetefromTn_> Oh man we tweaked the post quite a bit...
[19:51:15] <andypugh> And I am going to get rid of the move-to-clear height before a toolchange too, because that can be bad if you have actually already insterted the new (longer) lool.
[19:51:16] <PetefromTn_> It is not perfect but works great for me so far.
[19:52:03] <PetefromTn_> Huh I don't understand that?
[19:52:46] <PetefromTn_> YOu mean the safe Z height?
[19:52:49] <andypugh> The limiting speed in grease is 4400 and in oil is 5800. SO I don't think that they should be getting toasty-hot at 1000rpm?
[19:53:02] <Tom_itx> wouldn't think so
[19:53:15] <andypugh> Yes, CamBam puts in a "move to clear height" before the tool change.
[19:53:39] <Tom_itx> clear should clear any obstructions...
[19:53:40] <PetefromTn_> how is that a problem I still have that in there as well
[19:54:04] <Tom_itx> that is one reason i set my z well above any work or fixtures
[19:54:06] <PetefromTn_> Even the Haas Machines where I am working temporarily do that..
[19:54:36] <andypugh> So, if you previously had a short tool in, but have (manually) inserted a longer tool, but haven't done the G43, because you can see that a toolchange is almost the first thing in the program, then it can crash the tool.
[19:55:00] <Tom_itx> i actually move my model in the cad down 3" or so then post, using a 3" 123 block to set the tools from then
[19:55:34] <andypugh> Well, my machine is configured to quill-up for tool change. So rather often you get a qill-down to clear-height then a quill-up for tool change (in that order)
[19:55:41] <Tom_itx> you shouldn't be changing the tools until the program calls for it :)
[19:55:51] <PetefromTn_> Dunno why you would do that, all my tools use TLO's and I set them all before running anything.
[19:56:06] <Tom_itx> andypugh yeah once in a while my post will output such a move
[19:56:17] <Tom_itx> i haven't really been able to pinpoint where it's being inserted yet
[19:56:20] <andypugh> I have manual tool-change, but measured tool heights.
[19:56:40] <PetefromTn_> me too...so far anyways.
[19:56:43] <Tom_itx> i set mine up in the tool table and leave them in the holders
[19:57:26] <PetefromTn_> I did run into a problem with a CamBam Quirk yesterday tho.
[19:57:42] <PetefromTn_> When I made that part I showed pics of yesterday.
[19:57:53] <Tom_itx> andypugh, does the whole vertical head come off yours to become a horizontal cutter?
[19:58:00] <Tom_itx> driven off the same shaft?
[19:58:03] <andypugh> Another quirk (the same cause) was the set of canned-cycle holes I just drilled. So, it went to clear-height, then did a tool change (quill-up) then did the G98, so there was a full-travel rapid between each hole :-)
[19:58:03] <GuShH_> Loetmichel: Does Mach3 have any issues whatsoever with AMD processors?
[19:58:51] <PetefromTn_> I did the outside profile using a .dxf drawing I made and in CamBam used the Join feature to make it a polyline.
[19:58:52] <andypugh> Tom_itx: Yes, as can be seen in that photo I posted a few minutes ago, with the vertical head dangling from the roof, and the toolholder in the horizontal.
[19:59:08] <Tom_itx> that's why i asked
[19:59:16] <PetefromTn_> I then created MOP's off that like outside profiling etc..
[19:59:33] <PetefromTn_> Then I wanted to only Champfer certain parts of the outside profile.
[19:59:35] <andypugh> Ah, yes. When dragging polyline points in the XYplane, why do they move randomly in the Z plane?
[19:59:56] <PetefromTn_> So I exploded the polyline and created MOP's for that.
[20:00:31] <PetefromTn_> When i posted the enitre code the previous ops that used the unexploded polyline were broken and did not post despite being enabled when posted.
[20:00:32] <andypugh> PetefromTn_: Might have been easier to draw a boundary shape.
[20:01:22] <PetefromTn_> I asked about this on their forum and Lloyd suggested in the future that I copy and paste the polyline over top of the existing one somehow and explode that to do the individual MOP's...
[20:02:41] <Tom_itx> can you change a drawing line to become a tool path?
[20:03:01] <PetefromTn_> sure or you can just do an engrave no offset mill.
[20:03:10] <PetefromTn_> I actually did that on this part I just made..
[20:03:55] <andypugh> I wanted to corner-round a shape with changeing Z, and couldn't figure out how to do it. (I habd-coded in the end)
[20:04:25] <PetefromTn_> http://imagebin.org/301463
[20:04:51] <PetefromTn_> I actually drew two arc
[20:04:58] <XXCoder1> pete did your cnc do inside spots?
[20:05:05] <XXCoder1> if so, thats pretty smooth indeed.
[20:05:25] <XXCoder1> and how the heck do you do edge lips on pockets? I couldnt think of way.
[20:05:57] <PetefromTn_> lines to create a geometry to do a peel milling operation to help rough out the outside of the arcs before I did an outside profile..
[20:06:04] <andypugh> In the skip at eork today I found a 150-175mm micrometer and two 3-point bore comparators. Which are no longer in the skip.
[20:06:20] <PetefromTn_> Yeah the entire part was made on the Cincinatti Arrow 500 VMC with LinuxCNC...
[20:06:26] <XXCoder1> cool
[20:06:30] <PetefromTn_> Do you mean the champfer?
[20:06:39] <XXCoder1> yeah couldnt think of proper word
[20:06:49] <XXCoder1> that 45 angle before start of hole
[20:07:11] <PetefromTn_> Yeah that is a simple inside profile operation with a vee cutter and some offset and depth calculations to get the right champfer.
[20:08:03] <XXCoder1> cool. I guess its something I have to play with
[20:08:17] <humble_sea_bass> ooh. the unclampable part done got clamped
[20:09:08] <humble_sea_bass> XXCoder1: do you have basic CAD skills?
[20:09:20] <XXCoder1> well yes and no
[20:09:52] <XXCoder1> thats why I plan to go though tutorials and such to get skills properly gauged and filled in
[20:10:13] <humble_sea_bass> you doing this bass ackwards
[20:10:24] <XXCoder1> not surpised
[20:11:35] <humble_sea_bass> do yourself a solid and grab any old book about technical drawing and/or engineering graphics
[20:12:00] <XXCoder1> no prob
[20:12:45] <ChuangTzu> hmm
[20:12:49] <andypugh> Well, there is something to be said for machining first, you are less likely to design unmachinable things :-)
[20:12:50] <XXCoder1> I have been playing with inkscape, 3d render software and such on and off across years so cambam I picked up pretty quickly but since it works with something completely new
[20:13:12] <XXCoder1> I guess it will take me a bit
[20:13:36] <andypugh> Depending on what you are trying to make you are likely to find something parametric better than a direct modeller.
[20:13:39] <humble_sea_bass> well put andy, but I think having the syntax to communicate ideas is really important
[20:13:44] <ChuangTzu> i picked up solidworks and learned it in like half a day
[20:13:58] <ChuangTzu> but maybe i should go back and get one of these... books.... as you call them
[20:14:12] <XXCoder1> humble that is where my weak area is. I always forget it too. probably why I never could get a CS job lol
[20:14:52] <andypugh> Though one (free, slick, Windows / Mac only) option is Inventor Fusion. http://www.autodesk.com/products/fusion-360/overview
[20:15:01] <humble_sea_bass> http://www.ebay.com/itm/like/360882662371?lpid=82
[20:15:01] <CaptHindsight> ChuangTzu: the more difficult aspects of SW is merging different areas and getting all the tools to work right
[20:15:26] <XXCoder1> thanks for link
[20:15:49] <XXCoder1> wow so cheap
[20:15:53] <XXCoder1> its one of best eh
[20:15:56] <andypugh> I picked up Inventor basics in half a day, but I am still learning. And that is after spending 2 years working with it 8 hours a day.
[20:15:59] <humble_sea_bass> they are old as shit
[20:16:03] <humble_sea_bass> but the information is good
[20:16:10] <CaptHindsight> don't they teach drafting in high school anymore?
[20:16:14] <XXCoder1> yeah I have C book thats almost as old as C language lol
[20:16:24] <humble_sea_bass> Cap, you think schools are made of money??
[20:16:25] <ChuangTzu> yeah, i still learn a lot about solidworks
[20:16:26] <XXCoder1> capt I wouldnt know, I went to deaf schools
[20:16:34] <ChuangTzu> and there is still a lot i don't know
[20:16:39] <jdh> my daughter is taking a solidworks class
[20:16:44] <humble_sea_bass> XXCoder1: which one/
[20:16:46] <ChuangTzu> but i can do what i want with it and could from the first half day
[20:17:00] <ChuangTzu> but what i'm saying is, maybe i'd benefit from a book
[20:17:05] <CaptHindsight> humble_sea_bass: more like money pits
[20:17:15] <ChuangTzu> on actual drawing
[20:17:31] <ChuangTzu> i'm a scientist, i've never taken any classes on practical shit :)
[20:17:48] <humble_sea_bass> actual drawing nips a lot of bad habits in the bud
[20:18:01] <XXCoder1> dunno havent even looked at book for years now
[20:18:05] <CaptHindsight> humble_sea_bass: drawing nips?
[20:18:13] <XXCoder1> its amazing reference book for c
[20:18:18] <XXCoder1> 1980s
[20:18:19] <humble_sea_bass> yeah that sounded suboptimal
[20:18:43] <humble_sea_bass> XXCoder1: the new edition is like 150 bux and won't show you much
[20:18:59] <XXCoder1> its because of damned colleges
[20:19:01] <andypugh> I should have tried this earlier tonight. But I had forgotten it exists: http://openscam.org
[20:19:21] <XXCoder1> maybe one word change and your old edition is worthless and new book is $20 higher new than last one
[20:19:24] <humble_sea_bass> open >>>SCAM<<< dot org.
[20:19:39] <humble_sea_bass> sorry obama. keep your open out of my scam
[20:19:39] <Tom_itx> the more you machine the more you learn about fixtures too
[20:19:45] <CaptHindsight> why did they name it open-scam vs open-cam?
[20:20:06] <XXCoder1> lack of domain avil?
[20:20:35] <XXCoder1> read about its issues. some isnt good
[20:20:46] <andypugh> Why did they create expertsexchange and therapistfinder? Sometimes you read what you know it says.
[20:21:16] <andypugh> A new version was just announced on the LinuxCNC - dev list.
[20:21:24] <Tom_itx> anything like openscad?
[20:21:31] <Tom_itx> i'm not very fond of that
[20:22:00] <CaptHindsight> is that like Peter File?
[20:23:01] <Tom_itx> my cam has a preview similar to that
[20:23:16] <Tom_itx> i don't use it alot
[20:23:34] <CaptHindsight> http://www.youtube.com/watch?v=fTaKDnSIb4c
[20:23:36] <Tom_itx> i view the cutter paths more than the solid
[20:24:07] <XXCoder1> amazon has a hardcover copy for one penny + shipping.
[20:24:18] <XXCoder1> 1980 edition though. is it worse humble?
[20:25:34] <humble_sea_bass> dude it is fine
[20:26:18] <humble_sea_bass> get the 1936 version if they have it, pencils, ink and straight edges didn't make much progress over the decades
[20:26:39] <XXCoder1> okay will order when get back. dinner heh
[20:26:57] <humble_sea_bass> although I assume the 1980 version will be in that text book size we all know and love with more pictures and nicer paper
[20:31:51] <PetefromTn_Andro> Okay back now what'd I miss LOL.
[20:41:58] <XXCoder1> dinner yummy lol time to order
[20:42:44] <CaptHindsight> hp2200 doesn't focus under 5-6" and the lens is right on the sensor :( http://www.amazon.com/HP-Webcam-HD-2200-BR384AA-ABA/dp/B004UR9P9Q
[20:44:30] <somenewguy> yay, my ngcgui library is FINALLY organize properly in git
[20:44:52] <somenewguy> who wants to try notching thier vice with it
[20:45:00] <somenewguy> ...i mean enjoy its usefull functionality...
[20:45:06] <skunkworks> better yet - the table!
[20:45:36] <CaptHindsight> can you use it to notch your bed or table?
[20:45:37] <somenewguy> well lucky for me , with the shape of my head and fixture, generally it will crash into something removable before hitting the precious bed
[20:45:48] <skunkworks> I mean find any unforeseen bugs..
[20:45:48] <somenewguy> well, not on purpose lol
[20:45:57] <CaptHindsight> that's what Mach3 is for!
[20:46:18] <somenewguy> but in all seriousness, I am actaully ready to let ppl try out the few working routines, if they are interested in giving feedback
[20:46:32] <CaptHindsight> add counts even when your encoders aren't moving
[20:46:40] <CaptHindsight> it's a feature, not a bug
[20:46:46] <somenewguy> I run steppers, but that is why I left mach3
[20:47:00] <somenewguy> the code is so effecient in mach3, someteims the motors move even BEFORE you send a command
[20:47:06] <somenewguy> ....
[20:47:21] <somenewguy> can't blame the hardware, linuxcnc made everyone of my problems go away
[20:47:31] <CaptHindsight> predictive arcs
[20:47:45] <somenewguy> well, except for free time, since I have developed a bit of a love affair w/ writing CAM generators
[20:48:35] <somenewguy> I kind of want to post a link to my library on linuxcnc forum, but at the same time I'd rather have someone with brains take a quick looka t it before releasing it into the wild
[20:48:51] <somenewguy> seeing as how I have only had my mill 5 months or so
[20:49:10] <somenewguy> and running a 3d printer for 3 years did not really prep me for this
[20:49:14] <andypugh> night all
[20:49:25] <PetefromTn_Andro> Night andy..
[20:50:02] <humble_sea_bass> mach3 has a flappy bird module for your z axis?
[20:50:11] <somenewguy> hahaha
[20:50:35] <humble_sea_bass> machining hard mode
[20:50:55] <CaptHindsight> I have two notches in that matsuura now due to mach
[20:51:17] <PetefromTn_Andro> Huh?
[20:51:39] <CaptHindsight> hit the bed twice
[20:51:56] <PetefromTn_Andro> Oh no shit....that sucks.
[20:52:17] <CaptHindsight> the mpg adds counts even when the encoders aren't moving
[20:52:26] <CaptHindsight> piece of crap
[20:52:32] <PetefromTn_Andro> Wait you are running a Matsuura on crock3???
[20:52:49] <XXCoder1> shit
[20:52:56] <CaptHindsight> I'll grind off a few thousandths later from the bed
[20:52:56] <XXCoder1> hopefully bed isnt too damaged
[20:53:07] <humble_sea_bass> "sheeeeeeeeeeeet"
[20:53:18] <CaptHindsight> it came with mach
[20:53:30] <CaptHindsight> I was running a few parts and wham
[20:53:46] <PetefromTn_Andro> Oh I'm terribly sorry.
[20:53:47] <CaptHindsight> 30 years and not a scratch
[20:54:04] <Tom_itx> that'd be enough to piss ya off
[20:54:40] <CaptHindsight> no biggie, I caught it quick and it was only off by a few thousandths in the Z
[20:54:58] <CaptHindsight> 0.5" wide notch 2" long
[20:54:58] <PetefromTn_Andro> The shop I work in has a HUGE Haas VF8 machine and the massive table has two large circular rings cut out of it...
[20:55:22] <skunkworks> oops...
[20:55:39] <PetefromTn_Andro> I asked about it and was told NOT to ask about it LOL.
[20:55:46] <XXCoder1> I do expect to damage bed on my cnc. thats why I plan to place waste wood under workspace lol
[20:55:49] <humble_sea_bass> "guys lookit this"
[20:55:57] <XXCoder1> that way it lasts bit longer lol
[20:56:01] <somenewguy> I'm glad I nicked my vice the second day I had the mill
[20:56:05] <somenewguy> makes it easier to live with
[20:56:20] <somenewguy> PO hit the bed a few times, and for several inches impressivly
[20:56:43] <somenewguy> how do you mill a rectangle out of your bed, seriously?
[20:57:02] <humble_sea_bass> they were looking for hidden treasure
[20:57:06] <skunkworks> I think the worse we have so far is an 1/8 in cutter pulled out of the collet and cut a small slot in the angle plate before it broke
[20:57:07] <XXCoder1> lol
[20:57:42] <PetefromTn_Andro> My Cincinnati actually you would have to try hard to hit the bed the head does not come that close so you would need to either drill it or have a longer endmill.
[20:58:20] <skunkworks> I did form some aluminum when the hd started re-directing sectors.. (lost the tool change position because the var file got nuked.)
[20:58:26] <humble_sea_bass> in college this one group drove a drill bit into the bed and broke it off so this thing was in there like excalibur
[20:58:48] <PetefromTn_Andro> I never work directly on the table usually part is in vise or atop some 123 blocks or substrate.
[20:58:49] <somenewguy> I found one of those in my bed....
[20:59:01] <somenewguy> ^seriously
[20:59:08] <CaptHindsight> the other exciting thins about the mach setup is if the hydraulics are on and the e-stop, if you kill/power-off/crash the PC the spindle starts up at the last set speed
[20:59:16] <somenewguy> and make sure you know how high you are off the bed lol
[20:59:16] <XXCoder1> humble couldnt they mill it flush?
[20:59:49] <somenewguy> I found my excaliber when I was stoning the bed flat
[21:00:54] <PetefromTn_Andro> Capt when I first got my VMC for some reason when I powered up the control the vfd had no signal control yet and would ramp up to Max speed immediately. Scared the freaking shit out of me.
[21:01:48] <humble_sea_bass> XXCoder1: it got pulled out after a few days and basically we just had a hole on the table for the rest of semester I was tehre. I finished my work so I gave no fucks and graduated
[21:01:58] <XXCoder1> lol ok
[21:03:39] <CaptHindsight> http://www.3ders.org/articles/20140324-arevo-labs-introduces-carbon-fiber-reinforced-polymers-to-3d-print-ultra-strong-parts.html
[21:04:25] <XXCoder1> interesting. watching video now
[21:04:58] <CaptHindsight> this is the problem with patents, making composites is easy and obvious but now anyone making CNT reinforced filaments has to pay these guys?
[21:05:25] <XXCoder1> I suppose someone should have patented then made it open
[21:06:49] <CaptHindsight> well who knows what the actual patent says
[21:07:22] <CaptHindsight> everyone will just print parts in China
[21:08:58] <somenewguy> although fwiw, isn't the weakpoint in efp 3d printers layer adhesion, not material strength? didn't RTFA so maybe they are talking about somethign else
[21:10:07] <CaptHindsight> for repcraps yes, but not for some other FDM printers
[21:11:52] <CaptHindsight> plus composite materials can have more strength than plain PLA or ABS
[21:12:08] <PetefromTn_Andro> Night folks...
[21:13:13] <CaptHindsight> strength is a combination of materials and structure
[21:17:09] <somenewguy> so what do you guys think, should I link my ngcgui library on the forum, or should I wait untill I have used it more prior to showing it to ppl?
[21:17:24] <somenewguy> I have it hosted on github and have well marked experimental/useable branches
[21:17:54] <somenewguy> so i don't think anyone will mistake it for done, but at the same time i am hesitant to let just anyone try it out
[21:18:18] <skunkworks> I would post it.. More people trying it - the better. just say that it is experimental - use at your own risk
[21:18:27] <somenewguy> I am basically adding single function routines as I need them
[21:18:49] <somenewguy> it currenlty can mill an arbitrary circle or annulus pocket, rectangle, or just cut a rectangle
[21:19:08] <somenewguy> oh and trim the ends of a raw piece of stock to a certain angle and length (my current favorite)
[21:19:51] <somenewguy> also, does anyone know off the top of thie head what release brought ngcgui into the world?
[21:33:47] <CaptHindsight> http://www.youtube.com/watch?v=yjOLGGxnuGA V-FLASH
[21:40:03] <XXCoder1> geez
[21:40:11] <XXCoder1> someone there loves bvideo effect too much
[21:40:26] <XXCoder1> its almost ad for video effects lol
[21:41:29] <CaptHindsight> it's pretty bad
[21:42:31] <XXCoder1> "Look on what we can do with video!!" "Oh and theres some awesome 3d printer. I guess."
[21:43:49] <XXCoder1> I saw youtube of someone using printer that uses resin and projector
[21:44:40] <CaptHindsight> SLA/DLP
[21:45:23] <XXCoder1> thats diferent https://www.youtube.com/watch?v=KKR9gKJugN0
[21:46:16] <CaptHindsight> thats top down DLP
[21:47:01] <CaptHindsight> http://www.youtube.com/watch?v=0K9mDpWM7ns bottom up @1:40
[21:48:38] <XXCoder1> cool
[21:49:21] <XXCoder1> https://www.youtube.com/watch?v=i6Px6RSL9Ac
[21:51:29] <CaptHindsight> thats powder + binder using inkjet, then it gets sintered
[21:51:57] <XXCoder1> pretty cool
[21:52:32] <CaptHindsight> you can also use sand + binder to make a sand mold for casting
[21:57:56] <CaptHindsight> http://www.youtube.com/watch?v=eEZ2hTT4zPI ebeam direct EBDM
[21:58:39] <CaptHindsight> http://www.youtube.com/watch?v=A10XEZvkgbY
[21:59:47] <XXCoder1> interesting
[22:00:06] <XXCoder1> in some ways I bet this is better than cnc
[22:00:19] <XXCoder1> expecially when over 99% of material is removed
[22:00:26] <CaptHindsight> it's used along with it
[22:00:34] <XXCoder1> oh
[22:01:19] <CaptHindsight> http://www.youtube.com/watch?v=cRE-PzI6uZA DMLS direct metal laser sintering is similar
[22:01:41] <XXCoder1> lol I found link and are watchinjg already
[22:03:11] <CaptHindsight> DMLS requires less CNC finishing, but it's not as rapid as EBDM
[22:04:13] <R2E4> evening
[22:04:21] <XXCoder1> hey
[22:04:31] <CaptHindsight> http://www.youtube.com/watch?v=SYbw1oSzPVA Laser Deposition Technology (LDT) is another
[22:05:17] <XXCoder1> I bet all that is really expensibe
[22:05:59] <CaptHindsight> yes, in the west, the prices are dropping in China
[22:06:20] <XXCoder1> I wonder what would happen if it gets down to hobby level
[22:06:42] <CaptHindsight> burned fingers, blindness etc etc
[22:06:48] <XXCoder1> lol yep
[22:06:59] <R2E4> pcw:
[22:07:43] <R2E4> Installed a relay with a .1 second timer and the Z doiesn't drop at all.
[22:08:05] <CaptHindsight> XXCoder1: http://www.youtube.com/watch?v=uu6Lemm_Dts
[22:09:48] <XXCoder1> interesting. looks like early prototyping
[22:11:11] <XXCoder1> now something new http://sploid.gizmodo.com/a-magic-pancake-stacking-robot-machine-is-why-technolog-1550838724
[22:15:29] <XXCoder1> gonna go, thanks for links capt
[22:26:50] <R2E4> pcw_home: thanksfor your help onthe weekend. I got it fixed.
[23:04:06] <sabotender> moo
[23:04:11] <sabotender> hiya all
[23:04:23] <sabotender> XXCoder1: how goes the CNC making?
[23:05:18] <sabotender> CaptHindsight: can you recommend a good pci parallel port adapter? There are a few around. I don't think that I need anything special
[23:14:07] <XXCoder1> sabotender: ordered first stuff related to cnc - engineering drawing book and capilers
[23:14:18] <XXCoder1> latter just because I felt like it
[23:14:23] <zeeshan> what kind of calipers
[23:14:29] <sabotender> i was going to ask the same thing
[23:14:29] <zeeshan> and whyd you buy a book
[23:14:30] <sabotender> lol
[23:14:32] <XXCoder1> manual one
[23:14:35] <zeeshan> i could send you pdf
[23:14:43] <zeeshan> XXCoder1: i did tests with chinese calipers
[23:14:48] <zeeshan> they are just as good as mitutoyo.
[23:14:51] <XXCoder1> 1980 Good Copy Basic Technical Drawing
[23:14:58] <zeeshan> wtf
[23:15:00] <zeeshan> ancient!
[23:15:02] <XXCoder1> zee yeah I expected it to be shitty
[23:15:16] <XXCoder1> well it cost me all of penny + shippng. so $4 lol
[23:15:21] <zeeshan> haha
[23:15:25] <zeeshan> do you have an ipad
[23:15:26] <zeeshan> or something
[23:15:38] <XXCoder1> yeah on techinical stuff I prefer real book
[23:15:46] <CaptHindsight> sabotender: are you going to connect to a fpga or directly to a stepper driver?
[23:15:46] <XXCoder1> I love ebooks but on this case nah
[23:16:13] <sabotender> CaptHindsight: most likely directly to the stepper driver
[23:16:49] <CaptHindsight> just about any will work, some have broken EPP modes but that shouldn't effect you
[23:17:28] <sabotender> don't scare me now. I don't want to spend all this money to find that it won't interface properly :-P
[23:18:09] <CaptHindsight> moschip 980x boards have the broken EPP modes
[23:18:36] <CaptHindsight> read the linuxcnc forums on which ones to stay away from
[23:21:32] <sabotender> heh i didn't realise the forums existed :-P
[23:21:49] <CaptHindsight> http://www.linuxcnc.org/dapper/index.php/english/forum/38-general-linuxcnc-questions/27532-connecting-diy-glue-logic-to-linuxcnc-through-hal?start=20
[23:23:37] <CaptHindsight> http://www.plxtech.com/products/uart/oxpcie952 cards with these work but they are being EOLed
[23:24:12] <sabotender> oh I was in the process of finding the forums, but thank you for a more direct link
[23:24:29] <CaptHindsight> http://www.plxtech.com/products/uart/ox12pci840 is the PCI version chip
[23:26:08] <CaptHindsight> sabotender: but if you are connecting directly to a stepper driver then you don't need EPP anyway
[23:26:36] <CaptHindsight> EPP is used when connecting to a Mesa 7i43
[23:27:34] <sabotender> what use is that other board if it is possible to connect the stepper driver directly?
[23:27:51] <CaptHindsight> more IO
[23:27:57] <CaptHindsight> or servo's
[23:29:34] <sabotender> http://www.newegg.com/Product/Product.aspx?Item=N82E16815104231 I had my eye on that
[23:29:59] <CaptHindsight> http://www.mesanet.com/aiodaughter.html
[23:32:36] <sabotender> CaptHindsight: ah yeah, I understand their use now. And I don't require them
[23:36:52] <XXCoder1> openscam dont seem to accept tool size changes
[23:36:55] <CaptHindsight> http://galleryplus.ebayimg.com/ws/web/370948204091_1_0_1/1000x1000.jpg moschip 9815
[23:37:02] <XXCoder1> sim dont show any changes
[23:37:22] <sabotender> CaptHindsight: that is a bad card?
[23:37:43] <XXCoder1> oh I see why now
[23:37:58] <XXCoder1> been definiting 1 which apparently is second bit
[23:39:10] <XXCoder1> openscam dont support tool zero
[23:42:47] <XXCoder1> or "default tool"
[23:43:20] <sabotender> CaptHindsight: oh i see, that is a 9815; its the 980x boards that have issues
[23:58:30] <XXCoder1> lol took cat sample sencil and changed tool to 1 inch thicj ballnose
[23:58:49] <XXCoder1> results funny
[23:58:52] <sabotender> heh
[23:59:17] <sabotender> I'd better make sure to get a PCI to parallel card that supports legacy devices
[23:59:33] <XXCoder1> I'm glad I kept that ancient laptop
[23:59:53] <XXCoder1> hell if it works well enough I can break it apart and build awesome small case for it
