[00:04:09] <EO_> ok, deep breath
[00:04:15] <EO_> first time drilling @ 50kRPM
[00:04:20] <EO_> and going @ 10in/min
[00:04:29] * EO_ hopes this is acceptable to the drilling gods
[00:07:10] <anarchos> 50krpm??
[00:07:10] <anarchos> wow
[00:07:23] <anarchos> engraving?
[00:08:04] <EO_> 52k actually. 50k had a resonance with this drill bit
[00:08:14] <EO_> no, not engraving. drilling! :)
[00:08:35] <anarchos> crazy
[00:08:53] <EO_> yeah, that was FAST
[00:08:53] <anarchos> i'm still waiting on my tachometer to show up from china, but I think i'll be lucky if i break 4k :P
[00:09:04] <anarchos> what kind of machine do you have?
[00:09:10] <EO_> this spindle I installed recently goes up to 60kRPM
[00:10:49] <EO_> awww
[00:10:57] <EO_> drill change height was programmed too low
[00:11:01] <EO_> damn this won't clear!
[00:15:24] <PetefromTn_> what is the material... 50k rpm at 10 IPM sounds like burn city to me but I have no idea what you are doing.
[00:15:58] <toastydeath> that sounds like a jig grinder rather than a milling machine
[00:19:47] <EO_> yeah, I'm not sure if the feed per tooth is right :/
[00:19:51] <EO_> it's 63mil FR4
[00:19:54] <EO_> double sided 1oz copper
[00:20:05] <EO_> and the drills were 25mil and 30mil
[00:21:42] <EO_> it did produce good looking swarf though
[00:21:54] <Rab> That's the type of feed and speed you want for drilling FR4.
[00:23:53] <EO_> I should really calculator this
[00:32:19] <EO_> hmmm 10mil @ 52k is only 136SFM
[00:32:42] <LeelooMinai> tiny radius, tine sfm I guess
[00:32:47] <LeelooMinai> tiny*
[00:35:04] <LeelooMinai> EO_: You need 1 Mega RPM:)
[00:35:28] <zeeshan|2> yea baby
[00:35:30] <zeeshan|2> makin chips
[00:36:56] <EO_> .0004615384 <-- feed per tooth @ 52kRPM, in inches
[00:37:06] <EO_> errr 1/2 that
[00:37:13] <EO_> that's feed per rotation. 2-flute end mill
[00:37:47] <EO_> which seems to be in line with sanity
[00:38:22] <EO_> LeelooMinai: sadly 1 mega would be really expensive. 120k is the best I've found.
[00:38:38] <EO_> but that starts getting into exotic air motors with air bearings
[00:38:53] <EO_> too much of a hassle
[00:39:23] <LeelooMinai> I wonder what speed are those brushless motors they use in quadcopters:)
[00:40:30] <LeelooMinai> Hmm, they can do 20k it seems - this could actually work for pcb drilling, kind of maybe
[00:42:48] <LeelooMinai> Some can do 40k even
[00:43:48] <XXCoder> ah lost 5.7 million men
[00:44:11] <XXCoder> even so, they had resistance
[00:44:14] <LeelooMinai> EO_: btw, why do you want to drill pcbs? It's so cheap to order them from fabs now
[00:44:32] <XXCoder> https://en.wikipedia.org/wiki/World_War_I_casualties#Casualties_by_1914_borders
[00:45:57] <EO_> LeelooMinai: cuz I value quick-turn
[00:46:43] <EO_> LeelooMinai: it's for fast turn-around prototyping. really good when you're doing RF PCBs and you're battling parasitics. Or if you just suck in general and need to do things 10x over.
[00:47:27] <LeelooMinai> You need holes for RF? :)
[00:48:54] <LeelooMinai> I would think most components will be SMD
[00:49:11] <LeelooMinai> So just some isolation routing and prototype done?
[00:49:37] <LeelooMinai> Unless you make vias somehow
[00:49:40] <EO_> yeah, but you often needs lots of stitching to the ground plane underneath
[00:49:54] <EO_> this particular PCB tonight isn't RF though
[00:50:01] <LeelooMinai> But how do you do vias?
[00:50:12] <EO_> for non-rf you can just wire them
[00:50:15] <EO_> for RF you can plate them
[00:50:22] <EO_> there's videos out there
[00:50:34] <EO_> LPKF has a pretty easy system
[00:50:35] <LeelooMinai> Right, plate - a bit of pita at home.
[00:50:49] <LeelooMinai> all those chemicals and stuff:)
[00:51:00] <EO_> Doing anything but watching TV is a PITA at home.
[00:51:51] <LeelooMinai> There are all sorts of degrees of pita though:) Dealing with lots of chemicals is just not fun imho - but I guess some people are into that, not sure:)
[00:51:59] <PetefromTn_> I make parts WHILE watching TV LOL
[00:54:26] <EO_> hmmm well that didn't work :(
[00:54:48] <LeelooMinai> Bye bye drill bit? :)
[00:55:20] <EO_> no, bye bye traces
[00:55:24] <EO_> 1/2 the traces are missing
[00:55:33] <EO_> I think I set it to cut too deep
[00:55:52] <LeelooMinai> If only 1/2 maybe it's not level too
[00:56:05] <LeelooMinai> DO you have some negative air pressure to level the pcb?
[01:00:24] <EO_> no it's being held in a vise
[01:00:28] <EO_> so there's 2 problems
[01:00:35] <EO_> 1) I think it was too deep
[01:00:56] <EO_> 2) pcb2gcode spat out really sloppy g-code. it doesn't follow the contours of these fine features precisely at all
[01:04:13] <EO_> oh, no it didn't!
[01:04:21] <EO_> I bet the motion controller in linuxcnc caused these errors
[01:04:38] <EO_> cuz my acceleration was too low for the speed I was running
[01:07:44] <EO_> also, a piece of copper has wrapped itself around the endmill
[01:07:54] <EO_> that probably cleared more copper than it should have
[01:07:55] <tjtr33> this small spindle is fast, an outrunner, https://s3.amazonaws.com/ksr/assets/002/602/614/c7529d6f7fe1f198a3ef288f73cc3755_large.gif?1411026484
[01:08:10] <tjtr33> was part of a kickstarter
[01:08:26] <EO_> that looks menacing
[01:08:51] <tjtr33> heh 'exterminate'
[01:09:01] <EO_> sentry guns
[01:09:14] <EO_> PS: OpenSCAM is awesome @ visualizing g-code paths
[01:33:20] <Loetmichel> EO_: i use target 3001 to generate my isolation mill paths
[01:33:46] <Loetmichel> works well so far: http://www.cyrom.org/palbum/main.php?g2_itemId=14504
[01:33:55] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14507
[01:34:26] <Loetmichel> https://www.youtube.com/watch?v=jMXxjT4nNxg
[01:36:43] <PetefromTn_> Nice Loetmichel
[01:38:53] <EO_> k why is LinuxCNC doing this: http://bartk.us/dump/Screenshot-5.png
[01:39:05] <EO_> it has a nice clear white path defined, but it instead takes the red path which is gross
[01:39:42] <Loetmichel> insert a G64P0.05 in the code header
[01:39:47] <Loetmichel> and try again
[01:40:08] <Loetmichel> (or similar if using inch)
[01:40:46] <Loetmichel> you are using constant velocity i would think, not exact stop
[01:42:22] <EO_> ah, G61
[01:42:23] <EO_> I see
[01:42:46] <EO_> G64 P0.00500 ( set maximum deviation from commanded toolpath )
[01:42:49] <EO_> I had this
[01:42:50] <Loetmichel> G64 is exact stop mode, while the p0.05 allows for 0.05mm deviation for acceleration (makes the movements smoooter)
[01:42:51] <EO_> that's 5mil!
[01:42:59] <EO_> which is a huge deviation when you're milling 10 mil traces
[01:42:59] <EO_> heh
[01:43:25] <Loetmichel> i am using mm
[01:43:46] <EO_> 1mil = 0.025mm
[01:43:59] <EO_> a reasonable deviation value
[01:44:41] <Loetmichel> <. has to run to the compayny now, already 20 minutes late and not even sitting in the car....
[01:45:12] <EO_> yay irc! :)
[01:46:47] <renesis> lowering productivity since 1990
[01:47:33] <EO_> this G64 crap totally wiped out my other traces I bet. chewing 5mil off a 10mil trace.
[02:01:14] <MacGalempsy> I try to start taking it easy on teusdays, so the rest of the week isnt so stressful
[02:02:45] <PetefromTn_> why wait til tuesday?
[02:03:35] <Loetmichel> soo, arrived at the company. yay vnc! ;-)
[02:04:01] <EO_> double
[02:04:01] <EO_> NGC_Exporter::get_tolerance( void )
[02:04:01] <EO_> {
[02:04:01] <EO_> return 5.0/this->board->get_dpi();
[02:04:01] <EO_> }
[02:04:10] <EO_> ^^^ hardcoded G64 into pcb2gcode
[02:04:39] <Loetmichel> and tested yet?
[02:04:50] <EO_> yeah, the improve G64 did the trick
[02:05:08] <EO_> but it turns out the vise method still has Z problems.
[02:05:50] * Loetmichel uses target, which has its own builtin gcode exporter... and a nicer interface than eagle ;-)
[02:06:55] <Loetmichel> <- is firing up the mill to do some Noteboock psu Enclosures
[02:07:01] <Loetmichel> notebook
[02:07:34] <Loetmichel> like these: http://www.cyrom.org/palbum/main.php?g2_itemId=14778
[02:07:41] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14595
[02:08:51] <Loetmichel> these are paid their weight in gold because about 3h milling time per enclosure for the cooling ribs made of 4mm sheet aluminium
[02:09:05] <Loetmichel> :-)
[02:09:34] <Loetmichel> but since we do small militars computers runs we are good, the other companys charge the same insane amounts ;-)
[02:13:51] <PetefromTn_> WOOHOO I finally found my lost parallel
[02:14:01] <PetefromTn_> Been looking for the damn thing for months now heh
[02:18:46] <Deejay> moin
[02:21:33] <PetefromTn_> Good morning deejay
[02:21:46] <Deejay> hi PetefromTn_ \o/
[02:27:58] <PetefromTn_> :D
[02:36:36] <PetefromTn_> Gn8 all
[02:41:12] <EO_> I think I need to design a vacuum table
[02:41:17] <EO_> cuz this double sided tape stuff is butt
[02:42:07] <EO_> something with a loosely attached spoilboard I can re-level and replace regularly
[02:43:30] <Loetmichel> e0: thats easy
[02:43:56] <EO_> yeah, it sounds not too bad
[02:44:38] <Loetmichel> bit of spae wood...
[02:44:39] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=4035
[02:44:49] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=4038
[02:44:51] <EO_> yeah, perfect
[02:44:53] <Loetmichel> ... done ;-9
[02:44:58] <Loetmichel> spare
[02:45:38] <Loetmichel> or do it bigger in PVC:
[02:45:51] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14676
[02:46:03] <EO_> sexy
[02:46:10] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14682
[02:46:11] <EO_> I'll just make a small one for now
[02:46:16] <EO_> I have some spare 2x6 lumber :)
[02:46:19] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14685
[02:46:35] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14688
[02:46:38] <Loetmichel> :-9
[02:46:49] <Loetmichel> :-)
[02:47:03] <EO_> haha nice junction @ the bottom!
[02:47:25] <Loetmichel> ?
[02:47:37] <EO_> all the PVC lines taped into the vacuum hose
[02:48:59] * EO_ wonders if round columns would offer any benefit over square columns
[02:54:18] <Loetmichel> ah
[02:54:57] <Loetmichel> they are lust taped together, sealed with loads of hot melt glue and then plugged into the hose ;-)
[03:01:02] <EO_> 7" x 12" (17.78cm x 30.48cm) sounds like a good vacuum table for small PCBs
[03:14:55] <Jymmm> You guys have any idea on how I could turn a 6"ft bamboo pole into 3x 2ft sections? I thought like a pool cue threaded insert, but I need to maintain strength of the pole nad hot have t spit out where each insert is expoied in
[03:15:06] <Jymmm> six foot
[03:15:22] <Jymmm> exposed*
[03:41:31] <EO_> http://i.imgur.com/9e3eGNs.png
[03:41:32] <EO_> BAM
[03:41:34] <EO_> vacuum table!
[03:42:47] <FrozenCow> does anyone know whether it is possible to put a trigger on a component-pin instead of needing to poll it once every x seconds? (when creating a user-space component in python)
[03:48:16] <Loetmichel> Jymmm: use some glass rovings on the outside of the insert
[03:48:23] <Loetmichel> around the bamboo
[03:48:27] <Loetmichel> so it cant split
[03:48:52] <Loetmichel> will be nearly invisible if you are careful with the amount of epoxy
[03:49:39] <Loetmichel> e0: dont forget some plywood as the top plate!
[03:49:45] <Loetmichel> EO_
[03:49:55] <Jymmm> glass rovings ?
[03:50:34] <EO_> Loetmichel: yeah, those are separate pieces. still gotta figure out the vacuum entry port
[03:51:51] <Loetmichel> use some small pvc tubes and join them like i did
[03:51:55] <Loetmichel> its the easiest way
[03:51:59] <Jymmm> oh it's like FG strings
[03:52:03] <Jymmm> FG
[03:52:07] <Loetmichel> Jymmm: yes
[03:52:27] <Jymmm> pvc tubes for what now?
[03:52:37] <Loetmichel> that was for e0
[03:52:43] <Jymmm> oh heh
[03:52:47] <EO_> Loetmichel: nah I think I'd rather do a single hose inlet. Just had the wife buy me a $20 vacuum from walmat. It has a 1.5" hose. might work.
[03:53:18] <Loetmichel> EO_: as my CNC only has 80mm z movement i would frown on that
[03:53:31] <EO_> PCBs don't need Z!
[03:53:32] <EO_> heh
[03:54:11] <Loetmichel> my vacuum table is there all the time
[03:54:42] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=15256&g2_imageViewsIndex=1
[03:54:50] <Loetmichel> even when i do work with a vice
[03:55:11] <EO_> how do you keep that vise down?
[03:55:54] <Loetmichel> CA gluie ;-)
[03:55:56] <Loetmichel> -i
[03:56:39] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=15259&g2_imageViewsIndex=1
[04:00:32] <EO_> hmm stock is 1.5" tall, air hose is 1.25" OD...gettin tight in here
[04:05:18] <EO_> I suppose just a hole saw in the side of that prior to drilling ought to do the trick
[04:05:26] <EO_> s/drilling/milling/
[04:11:20] <EO_> drat, that'll crash into the spoilboard
[04:37:03] <EO_> http://i.imgur.com/M5nNEWp.png <-- BAM! 1.25" inlet port!
[04:46:52] <Loetmichel> EO_: as i said: use smaller hoses adn join them
[04:47:03] <Loetmichel> it also distributes the cvacuum better
[04:51:51] <EO_> too complicated
[07:49:33] <zeeshan|2> zz
[07:55:32] <jdh> sure
[08:57:25] <GMendez> Hi, is 0.05 mm for FERROR acceptable ? I'm using a MESA
[08:57:55] <JT-Shop> is that acceptable to you?
[09:00:41] <archivist> it is a small amount but a barn door to an electron, we do not know your machine or needs
[09:01:10] <ssi> lol
[09:02:19] <archivist> ssi see derivation of the unit called barn
[09:02:45] <ssi> A barn is defined as 10−28 m2 (100 fm2) and is approximately the cross sectional area of a uranium nucleus
[09:03:18] <_methods> but what about the door
[09:04:04] <pcw_home> GMendez: are you talking about ferror limits or magnitude of actual actual following errors
[09:04:08] <Jymmm> Bamboo rod thread wrapper, I kinda like it (other than the squeel) https://www.youtube.com/watch?v=eCQUQIfnNqM
[09:05:41] <Jymmm> I'm just not sure what defines the tightness of the wraps, the weight?
[09:07:35] <Jymmm> or the rod's feedrate
[09:08:16] <_methods> steps/mm lol
[09:15:35] <ssi> I've thought about adapting my g0602 to be a coil winder
[09:15:52] <GMendez> pcw_home: ferror limits software. Stepper motor. NEma 23. 1/128microsteps. belt driving
[09:16:24] <GMendez> looks acceptable for me but wanted a different view. 440*440*440mm working size
[09:17:04] <pcw_home> that should be fine (it depends on latency and how the stepgens are used)
[09:18:54] <pcw_home> that is, jitter in the servo thread will show up as ferrors so you may need to widen the limist if you have substantial jitter
[09:26:56] <GMendez> okay
[09:26:58] <GMendez> thanks :)
[09:27:12] <GMendez> no latency trouble, mesa generation
[09:29:20] <pcw_home> Servo thread latency can still be an issue
[09:31:07] <pcw_home> since the step generation runs in a a feedback loop where every
[09:31:08] <pcw_home> servo thread the current stepgen position is sampled at the servo thread time
[09:31:10] <pcw_home> and corrections are made
[10:07:27] <fluffybitchx> the dead battery is the one I thought it was... bleh. will need to try tracking down some batteries today.
[10:13:03] <ssi> I bought a little spartan6 dev board from a company called Scarab
[10:13:22] <ssi> mostly because it has USB jtag and they have an open source IDE to program it, arduino style
[10:13:36] <ssi> come to find out that their IDE still relies on the xilinx ise tools being installed
[10:13:39] <ssi> D:
[10:13:45] <ssi> I'll never get free from ISE :(
[10:20:52] <_methods> is ise that bad
[10:21:08] <ssi> it's not good
[10:21:12] <ssi> and it doesn't run on my platform
[10:21:15] <ssi> so it's a huge hassle for me
[10:21:17] <_methods> ahh
[10:22:17] <_methods> http://www.cnet.com/news/bitcoin-trader-mycoin-shutters-taking-387m-in-investor-funds/
[10:22:24] <_methods> oops sorry
[10:22:26] <_methods> wrong room
[10:41:57] <_methods> http://shop.actonglobal.com/collections/rocketskates/products/rocketskates-r10
[11:50:29] <s1dev> will a 14.5PA gear mesh with a 20PA gear? I have to get a gear today and I can't find a gear locally that's 20PA
[11:50:48] <archivist> not well at all
[11:50:52] <s1dev> as I understand it, there will be more noise and wear, but will it physically work
[11:51:38] <archivist> it may jamb, certainly will be lumpy, depends on clearancees
[11:57:36] <archivist> and are you comparing like with like, 14.5 are often DP designed, and metric gears are 20deg
[11:58:33] <archivist> measure OD and count teeth
[12:02:32] <archivist> temporary repair of one or two teeth is probably just as easy
[12:09:50] <archivist> s1dev, other trick, make a flycutter to match old gear, cut new one, will be good enough for a while
[12:10:35] <s1dev> unfortunately, I'm dealing with being out of time with no access to any significant amount of machinery
[12:11:43] <archivist> what damage to the gear as inserting a tooth a filing it up is a hand job
[12:13:13] <archivist> there are stockists if you can measure up properly
[12:14:23] <archivist> and there are people who can make at short notice if you ask and give enough detail
[12:18:54] <s1dev> thanks, I think I found a gear locally
[12:19:32] <archivist> where is local anyway
[12:20:32] <s1dev> Dallas
[12:21:36] <archivist> I am in the uk and make gears :)
[12:22:17] * s1dev really wants to get some gear cutters :(
[12:22:44] <archivist> a full set is....impossible
[12:36:51] <marmite> https://pbs.twimg.com/media/B9gJpEJCcAI85qs.jpg v2
[12:37:24] * SpeedEvil imagines the appropriate scene from the Matrix.
[12:37:34] <SpeedEvil> With the racks of gear-cutters sliding in.
[12:37:35] <Connor> marmite: what is that ?
[12:37:47] <marmite> vacuum pump
[12:37:57] <marmite> with 2 12v pumps and a chamber
[12:38:08] <marmite> outlet for vacuum and a onoff switch
[12:38:11] <Connor> what sort of pumps are those ?
[12:38:37] <marmite> those are vacuum pumps from a volvo v70 for the cruise controll
[12:38:49] <Connor> rofl
[12:38:53] <marmite> :D
[12:38:59] <marmite> they work really good
[12:39:13] <Connor> how loud are they?
[12:39:28] <marmite> not so mutch
[12:39:34] <marmite> my router sounds more:P
[12:40:32] <marmite> i have the board hanging on the wall next to my mill
[12:43:07] <_methods> http://www.amazon.com/gp/product/B0073HI94M/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B0073HI94M&linkCode=as2&tag=hothard-20
[12:43:11] <_methods> only one left
[12:43:16] <_methods> better buy it now lol
[12:45:06] <marmite> love teh review
[12:45:26] <marmite> It started as a soft, perfect note. A pureness beyond the normal comprehension. Only true sound engineers and audiophiles can have any hope to sense how great the fullness and exactness of that note is.
[12:45:30] <marmite> Ever since then, unicorns have been springing, fully formed, from my butt. No joke! And better, each unicorn has the same, perfect, innocent clarity that that first note did.
[12:46:33] <_methods> hahah
[12:46:38] <_methods> the reviews are awesome
[12:46:41] <marmite> :D
[12:49:51] <archivist> someone linked to a more expensive version of that junk the other day
[12:53:34] <_methods> the $10k one?
[12:54:17] <archivist> something like that price 9k?
[12:54:25] <_methods> yeah lol
[12:54:27] <_methods> insanity
[12:55:17] <renesis> mogami w/ neutrik ends ftmfw
[12:56:17] <_methods> audiophiles..........
[12:56:21] <renesis> ?
[12:56:39] <renesis> audiophile is a deragatory term, i work in audio gear R&D
[12:56:49] <_methods> yes it has become derogatory
[12:56:55] <_methods> unfortunately
[12:56:58] <renesis> my whole life
[12:57:13] <renesis> mogami is reasonably priced and awesome, and if youre not in neutrik is have little respect for your opinions
[12:57:32] <renesis> *"into neutrik, i"
[12:58:07] <renesis> also SOOW 12/2 makes the best speaker cable ever
[12:58:26] <renesis> fuck that clear plastic, quick-oxidizing copper bullshit
[13:00:04] <_methods> those neutrik connectors are nice
[13:00:31] <renesis> xlr or speakon? (answer in both cases is yes)
[13:00:42] <_methods> i'm looking at their industrial connectors
[13:00:50] <_methods> i just use cheap chinese shit for stereo stuff
[13:00:51] <renesis> but yeah, i cant stand switchcraft/canon style XLR
[13:00:54] <_methods> i could care less
[13:01:07] <renesis> their industrial stuff is neat
[13:01:11] <_methods> yeah
[13:01:15] <_methods> the nanocon connectors
[13:01:27] <renesis> they have a panel usb i kind of like except that its an adapter on both sides, no pinout
[13:02:07] <renesis> anyway bbl
[13:02:22] <renesis> (neutrik ftw!!1)
[13:02:26] <_methods> hehe
[13:09:22] <zeeshan1> hi guus, what size varistor would be sufficient for a brake solenod tgat cobsumes 1a at 24vdc
[13:09:51] <zeeshan1> sorry for typos, i am on mobile :)
[13:12:45] <marmite> hmm about 1 inch
[13:12:58] <marmite> :P
[13:14:12] <zeeshan1> lol
[13:14:31] <pcw_home> approximately this:
[13:14:32] <pcw_home> http://www.digikey.com/product-search/en?pv604=231&FV=fff4000a%2Cfff8003f%2Cfffc000a%2C8b40025&k=varistor&mnonly=0&newproducts=0&ColumnSort=0&page=1&quantity=0&ptm=0&fid=0&pageSize=25
[13:16:16] <SpeedEvil> I'd use a snubber.
[13:16:42] <SpeedEvil> Something like 10uF (film) and 24 ohm resistor in parallel
[13:16:46] <SpeedEvil> err
[13:16:47] <SpeedEvil> series
[13:16:51] <SpeedEvil> 22 ohm
[13:17:29] <pcw_home> hard to size a snubber without knowing the coil inductance
[13:18:46] <SpeedEvil> It can't be more than a few millihenries
[13:18:49] <SpeedEvil> err
[13:18:55] <SpeedEvil> actually - i'm thinking relays
[13:19:07] <pcw_home> no way could easily be 1 henry
[13:19:10] <zeeshan1> also the solenoid sees current in both directions
[13:19:21] <zeeshan1> id need a non polarized cap
[13:19:31] <SpeedEvil> yes - i said film.
[13:19:51] <zeeshan1> oh
[13:20:25] <zeeshan1> these guys have a 36 vrms 22mm mov, but has no other specs than that
[13:20:41] <pcw_home> That should be fine
[13:21:51] <zeeshan1> next size up is 63vrms 16mm
[13:21:55] <zeeshan1> i guyess physical size is proportional to energy absorbed capacity?
[13:22:03] <pcw_home> Yes
[13:22:34] <pcw_home> but 63V VRMS is 100 V which is too high
[13:23:16] <zeeshan1> ok ill grab the 36vrms one
[13:23:19] <pcw_home> ( well it would be a big improvement on no MOV/snubber )
[13:23:40] <pcw_home> yes thats ~ 50VDC
[13:24:15] <zeeshan1> next size down is 18vrms 21 mm
[13:24:49] <pcw_home> I would say that was too low
[13:24:59] <zeeshan1> kinda on the edge at 25vdc
[13:25:05] <zeeshan1> ok thank you!
[13:25:30] <zeeshan1> be back soon
[13:25:31] <pcw_home> yeah too low ( they are _not_ precise devices )
[13:26:53] <zeeshan1> actually before i go, to convert to pull up on the encoder signal at 7i77, 1/4watt resistor is ok?
[13:27:09] <zeeshan1> 2000 ohm
[13:32:06] <zeeshan1> whoops, 200 ohm
[13:32:54] <Tom_itx> i haven't done alot with varistors.. if it's 50v does it clamp at 50v?
[13:33:23] <pcw_home> Probably about 65V or so
[13:33:51] <Tom_itx> wouldn't be such a good thing for a 5v supply... better off with a zenner?
[13:34:30] <pcw_home> Yes MOVs are not suitable for low voltages
[13:34:35] <Tom_itx> zenner-resistor with the gate of a triac tied between or something
[13:34:52] <pcw_home> Yeah TVRs or crowbars are better
[13:35:11] <zeeshan1> lagg
[13:36:37] <Tom_itx> are mov's more for transient spikes on the supply?
[13:37:19] <pcw_home> Yes (at higher voltages)
[13:38:55] <pcw_home> also inherently bipolar and cheap
[13:42:13] <Tom_itx> pcw_home thanks for the 'abs' suggestion. I got the delay working nicely after that: http://tom-itx.no-ip.biz:81/~webpage/cnc/temp/logic1.jpg
[13:42:31] <Tom_itx> although i'm not sure how much i need yet
[13:43:24] <Tom_itx> the inhibit circuit gets about a 50ms pulse
[13:44:10] <pcw_home> probably even 25 ms will not make any noticeable performance difference
[13:44:35] <Tom_itx> i just need to make sure the relays flip long enough to make contact
[13:44:40] <pcw_home> (reversals on rigid tapping would be the test)
[13:44:44] <Tom_itx> yeah
[13:45:31] <Tom_itx> i'd use a small mosfet or something but the whole drive rides above GND by 60 some volts
[13:47:14] <pcw_home> yeah (shows how old I am, reminds me of hot chassis series 5 tube radios)
[13:47:20] <Tom_itx> heh
[13:47:42] <Tom_itx> i'll check and see if the isolation board i'm getting for it has a spare io on it, i'm not sure it does
[13:48:29] <pcw_home> an OPTO on a project board would do also
[13:48:54] <Tom_itx> i got some of those cheapo relay boards for arduino coming
[13:49:04] <Tom_itx> i'm gettin lazy the older i get
[13:49:32] <Tom_itx> i swore i had some little relays but the only thing i could find were some omron latching relays
[13:49:48] <Tom_itx> i know i have some hamlin HE101 around here somewhere
[13:49:53] <ssi> Tom_itx: I use those in a stereo attenuator I built
[13:50:02] <Tom_itx> which?
[13:50:09] <ssi> the omron latching relays
[13:50:12] <Tom_itx> ahh
[13:50:35] <Tom_itx> somebody traded me something for a dozen of em several years back
[13:50:36] <ssi> miniature latching DPDT relay
[13:50:36] <ssi> Omron G6JU-2P-Y-DC4.5
[13:50:39] <ssi> those specifically
[13:50:49] <ssi> there's sixteen of them in one attenuator
[13:50:58] <ssi> er no I guess there's 8
[13:51:01] <Tom_itx> G5AK 237P
[13:51:01] <ssi> cause they're DP
[13:51:06] <Tom_itx> if you ever need one...
[13:51:11] <ssi> lol k :)
[13:51:49] <Tom_itx> i don't think they have protection diodes on them where the hamlin one did
[13:52:08] <ssi> http://www.amb.org/audio/
[13:52:13] <ssi> that guy's stuff is pretty fun
[13:52:27] <Tom_itx> i was gonna fiddle with one to see if i could wire half of the DPDT to trigger the 2nd 'reset' coil so i could get just a short pulse from it
[13:52:40] <ssi> oh that'd be neat
[13:52:42] <Tom_itx> i bet it would work
[13:52:46] <ssi> like a mechanical one-shot
[13:52:46] <ssi> heh
[13:52:55] <Tom_itx> it would burn up if left on but all i need is a pulse
[13:53:19] <Tom_itx> and they're DIP size so pretty tiny
[13:54:00] <Tom_itx> i'd still need a couple diodes across them
[13:54:29] <Tom_itx> i wonder if signal diodes would be big enough
[13:54:55] <PetefromTn_> heh maybe I should have reconsidered champfering these things in the machine LOL
[13:57:14] <Rab> Tom_itx, I was browsing around your website and noticed the pulley upgrade project. What's the highest speed you've run with that configuration?
[13:59:58] <_methods> hahah always chamfer in the machine
[14:00:04] <_methods> it's worth the extra programming time
[14:01:18] <PetefromTn_> yeah well this part really would be still needing to be done on the second side by hand if you wanted any real accuracy of the cut...at least not without further fixturing and whatnot and there is not enough money in them to justify. So I just gotta sit here and suffer LOL...
[14:01:30] <PetefromTn_> BRB
[14:01:57] <_methods> trim router?
[14:02:06] <_methods> with guide bushing?
[14:02:12] <_methods> s/bushing/bearing
[14:02:23] <PetefromTn_> hm that is not a bad idea
[14:02:36] <_methods> too late now though you're probably already 3/4 done hehe
[14:04:39] <Tom_itx> Rab i think it will go up to about 5000 rpm
[14:05:14] <Tom_itx> i generally run it around 3k
[14:05:56] <Tom_itx> i haven't really used it since i changed belts over from the vbelts, just enough to see what rpm i was getting
[14:06:15] <Rab> Tom_itx, thanks. Planning a belt-drive spindle with either GT or MXL belts, but I'd like to do 10K or even higher and I'm not sure about safe range with toothed belts.
[14:07:49] <Rab> Round belts might be better for high speed low torque, but I have a bunch of toothed pulleys and belts on hand.
[14:13:49] <Tom_itx> these were GT2 9mm wide
[14:14:00] <Tom_itx> plenty big for this thing i'm sure
[14:14:38] <Tom_itx> you could probably find a data sheet for that i bet
[14:15:08] <PetefromTn_> _methods thanks for that idea man I never considered it.
[14:15:16] <Tom_itx> i got stock 1/4" bore and made them fit myself
[14:15:23] <PetefromTn_> I have done that TONS of times with wood working stuff not sure why I did not
[14:16:06] <Tom_itx> Rab, mine figured out to be around 1.2:1 iirc
[14:17:24] <Rab> "For GT2 belts, the maximum permitted speed is 7500 feet per minute (38 m/s)."
[14:17:26] <Tom_itx> i could look it up but yours will be different anyway
[14:17:41] <Rab> Tom_itx, most likely.
[14:18:11] <Tom_itx> what mill / spindle?
[14:18:28] <Tom_itx> better make sure the bearings are up for it too
[14:19:36] <Tom_itx> i figured mine would be ok since they make a high speed kit for it and doesn't include changing any bearings
[14:20:39] <Rab> Homemade spindle with 3x alleged "ABEC 7" bearings: http://reboots.g-cipher.net/ghettocnc/8mmspindle.jpg
[14:21:02] <Rab> Micro tooling, 1/8" 2-flute end mills and smaller.
[14:21:12] <Tom_itx> nice
[14:21:29] <Tom_itx> those get expensive
[14:21:54] <Rab> They do. I have a pretty good stock from eBay.
[14:22:24] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/etching/mills1.jpg
[14:22:37] <Tom_itx> those were about 20 bux ea locally
[14:22:48] <Tom_itx> the small one is 1/8" shank all carbide
[14:23:25] <Rab> You get what you pay for. I have some official LPKF micro tooling and it's really nice. Also no-name chinese which is rather poor.
[14:23:55] * LeelooMinai got two endmills from China today in the package too 6mm carbide ones - they look pretty good
[14:24:24] <LeelooMinai> Looked at them under a microscope:)
[14:25:10] <LeelooMinai> I hope to use them to mill aluminum
[14:25:54] <Rab> I have a bunch of conical carbide cutters which are terrible. I don't know how they screw up a conical cutter.
[14:26:37] <Rab> LeelooMinai, coolant/lube will probably help a lot.
[14:29:51] <Rab> If the 7500 ft/m figure is correct, assuming a 1.5" drive pulley, the safe maximum would be 19,000rpm...that's pretty good.
[14:30:39] <LeelooMinai> It's one of those spindles that need a motor to the side, right? Like that, what's the name, Tiag, Tieg, forgot:)
[14:30:53] <Rab> Taig, and yep!
[14:31:40] <LeelooMinai> I have small 800watt Chinese one, ER11: https://www.flickr.com/photos/100017731@N03/16272619078/
[14:31:51] <LeelooMinai> Kind of small collet, but it's for hobby only
[14:32:24] <LeelooMinai> So I am limited up to 7mm diameter endmills
[14:32:35] <Rab> Yeah, mine has ER11 too.
[14:33:17] <Rab> I looked at ordering one of those 800W spindles, but got spooked by horror stories. Seems like a $300+ gamble.
[14:33:19] <LeelooMinai> I would get bigger ones with ER16 at least, but I cannot get enough power for them from normal 110V socket in my room.
[14:33:39] <Rab> Are you using chinese VFD too?
[14:34:05] <LeelooMinai> I don't have VFD yet, but the spindle looks ok - rolls nicely and supposedly has 4 bearings inside, air cooled
[14:34:16] <LeelooMinai> I plan to buy VFD from automationdirect
[14:34:47] <JT-Shop> the GS2 can be controlled via modbus with LinuxCNC
[14:34:54] <LeelooMinai> It's more expensive but has modbus and nice documentation, etc. so I figured it's worth extra money over CHinese ones. It's still only $186 I think
[14:35:00] <JT-Shop> don't forget the serial cable and the braking resistor
[14:35:30] <LeelooMinai> RIght, that's the one I plan on buying. I bought cheap resistors from ebay as the automation direct ones are kind of expensive
[14:36:05] <LeelooMinai> Drives have ok price, but accessories seem to be costly:)
[14:37:39] <LeelooMinai> Rab: That 800watt spindle was not $300+ - they are under $200 if you search a bit
[14:37:49] <jdh> it is chinese
[14:38:10] <LeelooMinai> Right, they are not that expensive
[14:40:13] <jdh> the vfd feom keling will be the same chines vfd
[14:40:14] <Rab> LeelooMinai, that's for a spindle+VFD package. I haven't searched for solo spindles.
[14:42:34] <jdh> why would you buy them separate?
[14:44:24] <LeelooMinai> jdh: In my case I wanted to pay some extra for GS2 - as I wrote, it seems to have nicer features and good documentation.
[14:44:35] <jdh> my 1.5kw spindle runs off a 15amp circuit along with the steppers, computer, monitor, vacuum cleaner.
[14:45:06] <LeelooMinai> jdh: Normal 110V socket?
[14:45:37] <LeelooMinai> The VFDs that run from 110V can handle 750watt spindles max
[14:45:43] <zeeshan|2> man i hate going to that electronics store
[14:45:50] <zeeshan|2> everytime i get out of there, i spend 3x what i was supposed to
[14:45:50] <ssi> which
[14:45:55] <zeeshan|2> a local place
[14:45:55] <zeeshan|2> lol
[14:45:57] <ssi> o
[14:46:01] <zeeshan|2> i went to go buy irfp250
[14:46:04] <zeeshan|2> and varistor
[14:46:11] <zeeshan|2> they were supposed t obe like 12 bux or something
[14:46:16] <zeeshan|2> for a few of them
[14:46:25] <zeeshan|2> ended up spending 160
[14:46:28] <zeeshan|2> so i guess a lot more than 3x
[14:46:34] <zeeshan|2> i saw a lcr meter, esr meter
[14:46:37] <LeelooMinai> No one buys those things from "local places":)
[14:46:37] <zeeshan|2> had to have it
[14:47:10] <zeeshan|2> LeelooMinai: i get out of my house
[14:47:12] <zeeshan|2> unlike you
[14:47:13] <Rab> Damn, dogg: http://www.digikey.ca/product-detail/en/IRFP250MPBF/IRFP250MPBF-ND/2354106
[14:47:15] <ssi> lol
[14:47:16] <zeeshan|2> stay in your bubble.
[14:47:25] <zeeshan|2> and keep trying to figure out how to run a vfd off 110
[14:47:42] <LeelooMinai> jdh: So? How do you run that 1.5kW spindle from normal socket?
[14:47:43] <zeeshan|2> rabi bought 6 of them
[14:47:50] <zeeshan|2> they were 2 bux each locally
[14:47:58] <zeeshan|2> the varistors were like 50 cents
[14:48:03] <Rab> zeeshan|2, oic, that's good.
[14:48:49] <zeeshan|2> i actually prepared this text for when someone else brings up vfds:
[14:49:05] <jdh> normal 110v 15amp wall socket
[14:49:17] <zeeshan|2> I talked to a few people regarding using single phase 240V@15A MAX [3600VA] power to generate 3 phase [240v] using an inverter. The question was, what is the maximum amount of current output you can get out on the 3phase side. Knowing that _apparent_ power must remain the same in both and also the fact that apparent power in 3 phase systems is S = sqrt(3)*V*I, you can see that I = S/[sqrt(3)*V] =
[14:49:18] <jdh> with a few cascaded power strips
[14:49:19] <LeelooMinai> jdh: With what VFD?
[14:49:38] <zeeshan|2> 3600/[sqrt(3)*240] = 8.66A. Another way to think about it is compare a 1 hp single phase vs 1hp three phase motor. Assume perfect power factor (pf=1), then you can deduce that both motors require 746VA of apparent power. In the case of a single phase motor winding current is 746/240 = 3.1A, while the three phase winding current is 746/[sqrt(3)*240] = 1.8A. In both cases power remains the same.
[14:49:45] <zeeshan|2> What's the point of this conversation? If you indeed want to run a 3 phase motor using an inverter to go between single phase to three phase, you know that for a given voltage, you need sqrt(3) times the three phase motor current. Why the sqrt(3) factor? This comes from working out the math behind the fact that there are 3 current & voltage waves in a given period for three phase instead of just s
[14:49:51] <zeeshan|2> ingle as in single phase.
[14:49:53] <zeeshan|2> flood alert :-)
[14:50:25] <zeeshan|2> rab any updates on your massive haul?
[14:52:06] <Connor> What are you doing with the irfp250 and stuff zeeshan|2?
[14:52:17] <zeeshan|2> connor replacing them on the power supply for the drives
[14:52:19] <zeeshan|2> from the burnt drives
[14:52:26] <zeeshan|2> theyre the only things burn on it
[14:52:28] <zeeshan|2> *burnt
[14:52:31] <Jymmm> archivist: https://www.youtube.com/watch?v=MKikHxKeodA
[14:52:31] <LeelooMinai> jdh: All the VFDs I looked are end at 1HP if you are using 110V/15A
[14:52:33] <Rab> zeeshan|2, been super busy. Built a breakout "cape" for the BBB with Machinekit, spent several days messing with that. I'm almost ready to give up and either find a dedicated PC or keep using FleshCut for the time being.
[14:52:41] <Connor> The drivers themselves aren't toast ?
[14:52:48] <zeeshan|2> Connor: they are
[14:52:56] <zeeshan|2> but replacement drives without the ac supply
[14:52:57] <zeeshan|2> are dirt heap
[14:52:59] <zeeshan|2> like 50 $
[14:53:03] <zeeshan|2> used
[14:53:04] <Connor> ah
[14:53:09] <fluffybitchx> he's fixing the power supplies, or at least trying to with the assumption that there's no other damage, even though he doesn't have any drives to power with them.
[14:53:11] <zeeshan|2> but with ac it shoots up to 150-200
[14:53:32] <zeeshan|2> fluffybitchx: i knew these power supplys were working
[14:53:37] <zeeshan|2> till i plugged em into a shorted driver board
[14:53:42] <zeeshan|2> that fried the mosfet instantly
[14:54:05] <zeeshan|2> and if i dont play around with this stuff, ill never learn
[14:54:08] <zeeshan|2> so ill take a "chance"
[14:54:20] <zeeshan|2> the only thing on the power supply board i couldnt check was the ic on there
[14:54:29] <LeelooMinai> jdh: The only way I can think of would be, I don't know, somehow underpowering that spindle, but then you would not get high RPMs (that is close to 20k)
[14:54:32] <zeeshan|2> everything else checked out ok except the irfp250
[14:54:37] <jdh> leelo: it says nowforever d100s1r5b 16amp
[14:54:48] <fluffybitchx> thing is, plugging them into a short shouldn't have caused them to burn out the mosfets.
[14:55:01] <zeeshan|2> well thats what it erxactly did
[14:55:03] <jdh> I get 24k rpm unloaded
[14:55:08] <fluffybitchx> I'd expect the bridge to go first.
[14:55:13] <zeeshan|2> i had them powered up without the drives attached and they were outputting fine
[14:55:23] <zeeshan|2> the bridge is rated for 35A
[14:55:29] <zeeshan|2> it also was on a massive heatsink
[14:55:38] <zeeshan|2> in comparison to the mosfets
[14:55:48] <fluffybitchx> right, and the mosfets should have had ZERO amps going through them.
[14:55:59] <fluffybitchx> they're a shunt regulator, that only has current flow on overvoltage.
[14:56:14] <zeeshan|2> shrug we'll see
[14:57:14] <zeeshan|2> fluffybitchx: did you figure out why your drives are faulting?
[14:59:18] <fluffybitchx> no. if I set the current lower, they work.
[15:00:02] <zeeshan|2> overheating?
[15:00:11] <fluffybitchx> 2-3 seconds after power on and ice cold.
[15:00:21] <zeeshan|2> lame
[15:01:03] <fluffybitchx> my motors are reasonably low inductance, but still well over what the minimum for the drive is. I'm wondering if it isn't some little footnote the manual should have had, that you can't get the full current rating into a low-inductance motor, or something...
[15:01:44] <pcw_home> Maybe they didn't actual test that case
[15:02:19] <zeeshan|2> on my manual it says this:
[15:02:30] <zeeshan|2> If the drive is operated below the maximum rated voltage, the minimum load inductance requirement may be reduced.
[15:02:36] <fluffybitchx> the motors are 2.3mH, the drives rated for 0.5mH... so I'm not THAT close to it.
[15:02:42] <pcw_home> sort of expected since the ripple current goes up with decreasing inductance
[15:02:53] <fluffybitchx> I'm running them off 58V idle, 54V all three axis going.
[15:03:10] <pcw_home> and the overcurrent trip may be fast to protect the MOSFETs
[15:03:18] <zeeshan|2> pcw_home: i want to double check with you about wiring the encoders as pull down
[15:03:33] <zeeshan|2> i put a 200 ohm resistor in series with the signal?
[15:04:07] <zeeshan|2> fluffybitchx: be glad you have drives that dont self destruct
[15:04:08] <zeeshan|2> :-)
[15:04:13] <pcw_home> no, you connect it in parallel with the input
[15:04:14] <fluffybitchx> you rarely put resistors in series with signals.
[15:04:38] <zeeshan|2> okay so between gnd and signal
[15:06:16] <fluffybitchx> zeeshan|2: they're centent drives, built by mariss at gecko... he seems competent...
[15:07:13] <zeeshan|2> oh its between input and vcc
[15:07:20] <zeeshan|2> whoopz
[15:07:23] <zeeshan|2> fluffybitchx: nice
[15:08:59] <zeeshan|2> that guy dave @ eevblog
[15:09:03] <zeeshan|2> he's a pretty competent guy too
[15:09:10] <zeeshan|2> i was following his videos on diagnosing faults
[15:09:18] <tjb1> poor kid at work had a design review with 4 manufacturing engineers
[15:10:03] <zeeshan|2> lol
[15:11:06] <tjb1> got torn apart on stuff his boss should have taught him
[15:11:19] <tjb1> tapped hole depths within .050 of drill depth
[15:13:08] <_methods> lol
[15:13:17] <_methods> engineers know not to do that?
[15:13:32] <_methods> i've not seen many engineers that can actually make a real world part
[15:13:32] <fluffybitchx> blind-as-a-bat tap, instead of a usual blind tap?
[15:13:44] <_methods> real good at making imaginary parts
[15:13:47] * fluffybitchx can make parts!
[15:14:11] <zeeshan|2> _methods i hope thats somewhat changing
[15:14:25] <Tom_itx> pcw_home, should i email support to get a RMA to swap this 7I47 for the 7I47S or is that something you take care of?
[15:14:30] <_methods> not that i've seen
[15:14:36] <LeelooMinai> Yes, it's changing, now they make imaginary parts and 3D print them in ABS:)
[15:14:39] <_methods> cad has done nothing too help
[15:15:01] <_methods> it used to be you thought greatly and long before you put a drawing to print
[15:15:03] <zeeshan|2> do yuou know whats pathetic?
[15:15:09] <zeeshan|2> they spend 2 weeks teaching you gd&t
[15:15:26] <_methods> and you still don't know how to use it
[15:15:41] <zeeshan|2> you cant learn gd&t in 2 weeks
[15:15:42] <_methods> i sat in a clinic on gd&t with a company
[15:15:42] <fluffybitchx> gd&t?
[15:15:46] <_methods> it was hilarious
[15:15:53] <zeeshan|2> in college
[15:16:01] <_methods> it took the guys in there 6 hours to tolerance a block with 4 holes in it
[15:16:02] <zeeshan|2> we got 2 semesters of gd&t
[15:16:18] <_methods> funniest thing i think i've ever seen
[15:16:35] <zeeshan|2> you have clinics 6 hours long?
[15:16:38] <zeeshan|2> id be toast after that
[15:16:44] <_methods> it was week long
[15:16:46] <_methods> 8 hours
[15:16:50] <zeeshan|2> wtf
[15:16:53] <zeeshan|2> that'd own me
[15:17:15] <_methods> they flew the trainers from ford in to teach a gd&t clinic lol
[15:17:24] <zeeshan|2> lol
[15:17:25] <_methods> for a company i was doing contract work for
[15:17:49] <zeeshan|2> the worst is when EE's try to design mechanical parts
[15:17:55] <_methods> gd&t isn't really that difficult if you follow the damn rules
[15:18:05] <zeeshan|2> i have like a 60 page handbook
[15:18:13] <zeeshan|2> the ones i get confused on
[15:18:22] <fluffybitchx> I'm a jack of all trades. what does that count as?
[15:18:32] <zeeshan|2> is when you do profile geometric tolerancing
[15:18:38] <zeeshan|2> i always have to refer back to an example for that
[15:18:51] <_methods> assymetrical profile lol
[15:19:35] <_methods> gd&t really kills the old timers out on the floor though
[15:19:41] <zeeshan|2> man i cant wait to work back in industry again
[15:19:42] <_methods> you want to hear some moaning and groaning
[15:19:48] <zeeshan|2> so tired of this masters research bs
[15:19:50] <zeeshan|2> i wanan do some real work
[15:20:15] <zeeshan|2> yea a lot of machinists dont understand it fully
[15:20:19] <zeeshan|2> nor do the engineers
[15:20:21] <zeeshan|2> so i dont blame em
[15:20:39] <zeeshan|2> the guys who really seem to understand it well are in quality control
[15:20:58] <_methods> yeah it really is better than standard dimensioning for clearing up tolerance errors
[15:21:15] <_methods> cause they deal with it all day
[15:21:16] <CaptHindsight> heh, or ME's trying to assemble electrical parts :)
[15:21:25] <zeeshan|2> CaptHindsight: exactly!
[15:21:25] <_methods> and some measurements can't even be made on the floor
[15:21:31] <zeeshan|2> look me and my circuit problems :-)
[15:21:35] <_methods> some of those profile tolerances need a cmm
[15:21:44] <zeeshan|2> but im forcing myself to lear nit, so i have more clue about it than the average ME
[15:22:02] <zeeshan|2> _methods: yes
[15:22:09] <_methods> everyone knows an EE is smarter than all the other engineers
[15:22:16] <fluffybitchx> I know a bit of EE, ME, CE, CS, BA,... umm...
[15:22:18] <zeeshan|2> haha hahahaha hahaha
[15:22:20] <zeeshan|2> hahhahaha!
[15:22:45] <_methods> it's the last question on yoru ME exam
[15:22:54] <_methods> who's the smartest engineer
[15:22:58] <_methods> dah EE
[15:23:01] <ssi> nope
[15:23:04] <ssi> software engineer
[15:23:08] <ssi> because it's the only career that pays
[15:23:22] <_methods> i hate it when they attach engineer to the end of software
[15:23:55] <_methods> unless you're programming assembly
[15:24:09] <_methods> then feel free to attach lol
[15:24:13] <ssi> that's a pretty arbitrary distinction :P
[15:24:24] <LeelooMinai> I don't see why assembly would make the difference
[15:24:29] <CaptHindsight> a software engineer also has to be able to follow the confused minds of the developers before them, with most other engineering fields it's dictated by logic and scientific facts
[15:24:48] <_methods> logic and scientific facts
[15:24:53] <_methods> key words lol
[15:27:48] <LeelooMinai> Enginner is someone who uses knowledge to make design something useful - that covers a lot of areas.
[15:28:11] <LeelooMinai> s/make//
[15:29:32] <CaptHindsight> social engineer
[15:29:40] <_methods> lol
[15:29:50] <_methods> custodial engineer
[15:30:15] <_methods> hmm now that i think about it maybe software engineer is fitting
[15:31:58] <zeeshan|2> to be honest there's real no good answer to the question "whos the smartest engineer"
[15:32:09] <zeeshan|2> anyone who says its a specific one is just being a tard
[15:32:13] <_methods> no it's the EE
[15:32:15] <CaptHindsight> define smart and engineer
[15:32:15] <_methods> everyone knows
[15:32:21] <LeelooMinai> Silly question. SIlly answers.
[15:32:28] <zeeshan|2> ive seen some of the shit chem eng do
[15:32:28] <_methods> you know it's not the civil engineer lol
[15:32:36] <zeeshan|2> i'd never want to do that non sense
[15:32:40] <zeeshan|2> their mixing problems are retarded
[15:32:47] <zeeshan|2> and process control
[15:33:01] <zeeshan|2> i actually took a civ eng grad course last semester
[15:33:07] <zeeshan|2> gave me a huge respect for civ eng
[15:33:14] <zeeshan|2> their mechanics might be the same
[15:33:22] <zeeshan|2> but how they apply it is quite different
[15:33:24] <CaptHindsight> zeeshan|2: it's very different from electronics and mechanical engineering
[15:33:29] <zeeshan|2> they have things like shear wall
[15:33:38] <tjb1> _methods: I am a ME
[15:33:41] <tjb1> I think I do pretty good :P
[15:33:42] <zeeshan|2> elevactor shaft buckling etc
[15:33:45] <_methods> hahah
[15:33:52] <CaptHindsight> it's filled full of secret sauces to make things work well
[15:33:53] <zeeshan|2> tjb1: high 5 me too
[15:33:54] <LeelooMinai> I am ME, myself and I too:)
[15:33:57] <_methods> i'm just stirring
[15:34:17] <tjb1> I try to drop it to .00 whenever I can
[15:34:18] <zeeshan|2> CaptHindsight: yes
[15:34:58] <zeeshan|2> i used to think it was the ppl who graduated with barely passing that made engineers look bad
[15:35:03] <fluffybitchx> the worst engineers are cost engineers
[15:35:08] <zeeshan|2> i have a friend who has a 3.95 gpa
[15:35:15] <CaptHindsight> very few CE's cross over into EE or ME, it's interesting since they tend to look at machines and controllers as magic boxes
[15:35:18] <zeeshan|2> he refuses to step into the machine shop to build his capstone project
[15:35:25] <zeeshan|2> cause he thinks machining is useless
[15:35:30] <zeeshan|2> he doesnt need to it design fluid systems
[15:35:31] <zeeshan|2> LOL
[15:35:39] <tjb1> CaptHindsight: What is a CE?
[15:35:42] <zeeshan|2> he makes his group members do the machining
[15:35:48] <_methods> civil engineer
[15:35:55] <LeelooMinai> CaptHindsight: Strangely there's a lot of people that went from CE into playing with EE and ME on irc
[15:35:58] <_methods> the dumbest of the engineers
[15:36:08] <tjb1> I'm just a CAD slut
[15:36:16] <tjb1> I don't get to do any machining :(
[15:36:26] <zeeshan|2> you wont likely
[15:36:26] <_methods> they're so dumb they still use autocad for everything
[15:36:31] <zeeshan|2> but you need a good base for it
[15:36:37] <zeeshan|2> at eaton , even though iwas making enclosures
[15:36:44] <zeeshan|2> i asked my boss if i could spend a week on the floor
[15:36:45] <CaptHindsight> tjb1: http://en.wikipedia.org/wiki/Chemical_engineering
[15:36:47] <zeeshan|2> he let me
[15:36:48] <tjb1> eaton eh, zeeshan|2 horseheads?
[15:37:04] <zeeshan|2> got to talk to the workers, see the processes
[15:37:14] <zeeshan|2> the dies they had for their punching turret pressses
[15:37:27] <zeeshan|2> the tolerances they could hold on brake press, flanging tolerance
[15:38:03] <zeeshan|2> horseheads?
[15:38:07] <tjb1> zeeshan|2: guess not
[15:38:10] <zeeshan|2> hehe
[15:38:11] <tjb1> there is an eaton here
[15:38:13] <zeeshan|2> eaton the electrical company
[15:38:16] <tjb1> horseheads/elmira/corning
[15:38:24] <_methods> eaton is a large company lol
[15:38:45] <zeeshan|2> ive worked at like 5 different places
[15:38:53] <zeeshan|2> won't name them, but two of them were also fortune 500
[15:38:59] <zeeshan|2> eaton is an amazing place to work for
[15:39:18] <zeeshan|2> i've never worked at ap lace where people are so crazy nice
[15:39:23] <LeelooMinai> I think it's the accesability/ppopularity of microcontrollerls and the infamous Arduinos that made CS people (and others) interested in EE, kind of indirectly as you need EE knowledge to built devices around them.
[15:40:22] <zeeshan|2> tjb1: do you do any stress analysis?
[15:40:34] <tjb1> zeeshan|2: Kind of
[15:40:42] <tjb1> I look at the pictures but dont really understand most of the numbers
[15:40:50] <CaptHindsight> LeelooMinai: do to the easy to use dev tools and the relative low cost of the *duinos?
[15:41:03] <zeeshan|2> tjb1: i mean not fea completely
[15:41:10] <zeeshan|2> but like say good ol bending of beams
[15:41:16] <tjb1> no
[15:41:16] <zeeshan|2> or trying to size bolts
[15:41:20] <zeeshan|2> or bolt patterns etc
[15:41:31] <tjb1> I have no training in Inventor
[15:41:46] <tjb1> unless you count that week in college of "read the packet and make this block"
[15:41:53] <zeeshan|2> LOL
[15:41:55] <CaptHindsight> do/due
[15:42:03] <LeelooMinai> CaptHindsight: It all kind of exploded at some point, so everything: low cost, lots of projects on the web, information, "hacking", robots, quadcopters, etc. - gets people interested in electronics
[15:42:06] <zeeshan|2> tjb1: ive done both technical college and university
[15:42:14] <zeeshan|2> its crazy how different they are
[15:42:20] <zeeshan|2> i had 6 semesters of CAD
[15:42:25] <tjb1> zeeshan|2: I have a bachelors in manufacturing engineering but they didnt do any Solidworks/Inventor training
[15:42:27] <zeeshan|2> univ was 2 course lol
[15:42:32] <zeeshan|2> er 1 course i mean
[15:42:40] <tjb1> I signed up for one but it got canceled because it didnt have enough people
[15:43:03] <fluffybitchx> everything
[15:43:11] <fluffybitchx> everything I know is from having to do it. heh.
[15:43:18] <CaptHindsight> LeelooMinai: I see more that they are interested in MakerStuff vs elelctronics
[15:43:21] <tjb1> I am self taught Inventor
[15:43:22] <LeelooMinai> To build, say, a quadcopter you need knowledge from CS area, electronics, some mechanical engineering needs to be done
[15:43:23] <zeeshan|2> tjb1: you can follow tutorials and stuff
[15:43:27] <zeeshan|2> and learn it yourself
[15:43:35] <tjb1> zeeshan|2: I am pretty good with it but stuff like surfaces is beyond me
[15:43:37] <zeeshan|2> but what makes you get the edge is when you watch a super user
[15:43:40] <zeeshan|2> do it
[15:43:46] <zeeshan|2> you pick up so many things you can do faster
[15:43:55] <tjb1> I dabbled a bit in dynamic simulation for an unknown force
[15:44:05] <zeeshan|2> im not talking about the packages :P
[15:44:10] <zeeshan|2> im talking strictly modeling
[15:44:12] <zeeshan|2> and assembly
[15:44:40] <CaptHindsight> tjb1: jesus, satan, oprah etc?
[15:44:43] <tjb1> All of surface modeling in Inventor is beyond me
[15:44:47] <LeelooMinai> CaptHindsight: Not everyone goes nto details in the same degree, but still - it's a golden age for this due to many factors. Having internet and access to all the info you won't is not bad either:)
[15:44:48] <_methods> hahahahha
[15:44:53] <_methods> oprah
[15:45:19] <LeelooMinai> want*

[15:46:05] <tjb1> Force for shocks on that hood
[15:46:24] <CaptHindsight> I haven't looked at Inventor in several years. Whats the surface modeling like? Compared to Creo, NX, Catia etc?
[15:46:47] <zeeshan|2> tjb1: what is that
[15:46:51] <zeeshan|2> i see a motor
[15:46:57] <zeeshan|2> on a shock absorber :D
[15:47:04] <zeeshan|2> or a heim joint
[15:47:04] <zeeshan|2> cant tell
[15:47:06] <tjb1> zeeshan|2: bolt headstocks to it
[15:47:11] <tjb1> to run bearings in before grinding
[15:47:30] <tjb1> https://www.dropbox.com/s/m1dpp9eno8y0s5c/2014-10-30%2016.00.33.jpg?dl=0
[15:47:57] <JT-Shop> tjb1, I have two thermocouples that came with the ramps board
[15:47:59] <zeeshan|2> nice
[15:48:05] <tjb1> JT-Shop: thermocouples or thermistors?
[15:48:15] <tjb1> zeeshan|2: something like 22 different headstocks bolt to that base
[15:48:17] <JT-Shop> thermistors sorry
[15:48:19] <_methods> inventor surface modeling is horrible
[15:48:31] <_methods> i still think you can't even open 4 viewports
[15:48:35] <JT-Shop> and 5 little heat sinks that I assume go on the driver chip?
[15:48:44] <tjb1> JT-Shop: correct
[15:48:46] <zeeshan|2> how do you like that routing package on inventor
[15:48:50] <zeeshan|2> i think its pretty sweet!
[15:48:54] <tjb1> zeeshan|2: well its a bastard
[15:49:10] <tjb1> probably because I have no idea how to use it
[15:49:29] <zeeshan|2> if you interface with autocad electrical
[15:49:35] <zeeshan|2> er autocad mechanical
[15:49:45] <zeeshan|2> you can take a drawing and link it to the model :D
[15:49:54] <zeeshan|2> and auto route and fix up the issues
[15:50:06] <zeeshan|2> ive seen it done, but never did it myself. only did it for electrical
[15:50:25] <tjb1> zeeshan|2: I didnt use inventor coupling though
[15:50:28] <tjb1> those are all from mcmaster
[15:50:58] <zeeshan|2> thats okay, i think you just have to define a pin/port for the part
[15:51:06] <zeeshan|2> that needs to match with the drawing
[15:51:15] <fluffybitchx> I need to learn a CAD program. so far the only cad I've done is 2-d for a plasma cutter, and I wouldn't say I was entirely competent.
[15:51:23] <tjb1> zeeshan|2: https://www.dropbox.com/s/ia6epzt9agz0e6r/2014-10-30%2016.01.05.jpg?dl=0
[15:51:34] <fluffybitchx> plasma cutters rock, by the way.
[15:51:39] <zeeshan|2> thats a pretty damn thick plate
[15:51:40] <zeeshan|2> for mounting :)
[15:51:49] <tjb1> zeeshan|2: cheaper than the thin stuff :P
[15:52:05] <Connor> tjb1: What is that ?
[15:52:07] <tjb1> yes I know its stupid
[15:52:16] <tjb1> Connor: which part?
[15:52:18] <zeeshan|2> hey, if thats whats cheaper
[15:52:20] <zeeshan|2> hell yea!
[15:52:23] <Connor> The whole thing
[15:52:25] <tjb1> Its actually nifty bar too...
[15:52:33] <tjb1> Connor: run in bench for headstocks
[15:52:33] <fluffybitchx> any suggestions for a free cad program? right now I mostly want simple 3-axis stuff, no need for full CSG...
[15:52:35] <zeeshan|2> i see 2 regulators
[15:52:45] <zeeshan|2> a vvalve
[15:52:53] <zeeshan|2> i dont know what that blue thing with the brass filter is
[15:52:58] <zeeshan|2> solnoid ?
[15:52:59] <tjb1> another valve
[15:53:06] <Connor> okay... Why do you need that? and why the pneumatics ?
[15:53:06] <CaptHindsight> FreeCAD
[15:53:06] <tjb1> controls rod lock on cylinder
[15:53:19] <tjb1> Connor: distributes the grease in the bearings
[15:53:28] <tjb1> and the pneumatics are to tighten the belt on the motor

[15:53:53] <tjb1> the linear rail was "free"
[15:53:55] <fluffybitchx> I installed freecad the other day. I've found it very buggy, and I couldn't find out how to make it do what I wanted, which was draw a simple diagram with heights of each part specified...
[15:54:06] <tjb1> fluffybitchx: I think Inventor Fusion is free
[15:54:16] <zeeshan|2> ilegal downloads
[15:54:17] <zeeshan|2> !
[15:54:53] <fluffybitchx> in order to do that, I had to make a bunch of separate sketches, and subtract each of them from an extruded first one.
[15:55:45] <tjb1> fluffybitchx: http://www.123dapp.com/design
[15:56:07] <zeeshan|2> thats the difference between inventor fusion
[15:56:13] <zeeshan|2> and inventor pro
[15:56:17] <fluffybitchx> ... and runs on pleasant operating systems.
[15:56:40] <tjb1> zeeshan|2: valves have backflow
[15:56:48] <tjb1> flow valves on the back to control cylinder speed
[15:56:56] <tjb1> rod lock is integrated with e-stop on control
[15:59:00] <zeeshan|2> nice
[15:59:52] <tjb1> built it, turned air on, motor wouldnt lift
[15:59:55] <tjb1> about had a heart attack
[16:00:11] <tjb1> flow valves were closed :)
[16:00:34] <zeeshan|2> haha
[16:03:18] <fluffybitchx> I guess my next project is to grind flats
[16:06:30] <fluffybitchx> I don't know where either of my angle grinders are. bleh.
[16:06:49] <zeeshan|2> file it
[16:06:50] <zeeshan|2> :-)
[16:06:57] <zeeshan|2> i thought you were bad with a grinder!
[16:07:37] <fluffybitchx> I'm worse with a file. and way, way too lazy.
[16:08:12] <fluffybitchx> I have three angle grinders. a makita, a harbor freight, and an ancient b&d big one. I know where the last one is - on loan to someone who might never return it...
[16:08:36] <fluffybitchx> I could just give HF the $10 for another one...
[16:08:49] <zeeshan|2> file is cheaper
[16:08:50] <zeeshan|2> !
[16:09:34] <fluffybitchx> ... have you tried buying a good file lately
[16:09:35] <fluffybitchx> ?
[16:09:46] <zeeshan|2> yea
[16:09:51] <zeeshan|2> homedepot sells nicholson files
[16:09:55] <fluffybitchx> also $10. :P
[16:09:58] <fluffybitchx> no home despot here
[16:10:48] <fluffybitchx> hrmm, I should have plugs between my drives and the breakout board. think molex is good enough?
[16:11:13] <fluffybitchx> having to dick around with a bunch of tiny screws to move things around is annoying.
[16:11:25] <TekniQue> molex sells a wide range of different connectors, surely some of them are good enough ;)
[16:11:38] <fluffybitchx> think the cheapo ones waldom sells kits of are good enough? :P
[16:13:40] <zeeshan|2> amps / voltaghe?
[16:13:55] <fluffybitchx> .02 amps, 5 volts.
[16:14:41] <fluffybitchx> "good enough" in this case more refers to the lack of shielding and reliability, not ratings.
[16:17:36] <bobo_> zeeshan the nicholson files of today an't the same as they were when i was your age
[16:17:47] <zeeshan|2> they work! :P
[16:18:15] <bobo_> so do HF ones
[16:20:06] <Deejay> gn8
[16:20:36] <fluffybitchx> yay, found my makita. and it even has a good wheel!
[16:21:17] <bobo_> zeeshan connect that MOV up at the brake not out at end of some extension cord
[16:22:32] <fluffybitchx> spacex trying again in less than an hour. what do you think will hold up the launch this time? heh
[16:23:44] <bobo_> zeeshan glad to hear your moving the drives to L1 is working
[16:23:59] <CaptHindsight> I've been busy, whats the latest on the mystery of the exploding zeeshan|2 drives?
[16:24:27] <zeeshan|2> l2 to l1 seemed to fix it
[16:24:51] <fluffybitchx> he thinks moving it to the other line has fixed it, but he refuses to perform a neutral resistance test.
[16:25:11] <CaptHindsight> interesting, I'd like to see what a storage scope has to say about the power on those legs
[16:25:17] <bobo_> so what is now on L2 to Com ?
[16:25:32] <zeeshan|2> everything is on l1 to n now
[16:25:39] <zeeshan|2> except hydraulic vfd
[16:25:42] <zeeshan|2> thats still only l2 to n
[16:26:06] <zeeshan|2> im gonna finish up wiring my spindle encoder
[16:26:13] <zeeshan|2> hook up this varistor
[16:26:17] <fluffybitchx> I need to build a spindle encoder...
[16:26:18] <zeeshan|2> and make some chip videos! :P
[16:27:13] <bobo_> varistor ? i thought you got a MOV ?
[16:27:34] <zeeshan|2> a mov is a varistor :)
[16:30:34] <bobo_> not in my world but they may have changed
[16:31:39] <fluffybitchx> ... a metal oxide varistor was ever not a varistor?
[16:32:01] <bobo_> to me a MoV is a clamp device zener
[16:32:27] <fluffybitchx> a MOV is a Metal Oxide Varistor.
[16:32:31] <fluffybitchx> that's what MOV is.
[16:35:22] <bobo_> varistor changes ohm value over longer time constant than MOV, and recover time is longer than MOV
[16:36:36] <fluffybitchx> ... MOV is an acronym. It means Metal Oxide Varistor.
[16:36:56] <fluffybitchx> by definition, a MOV is a Varistor.
[16:36:57] <zeeshan|2> i kinda see bobo's point
[16:37:12] <zeeshan|2> its like oh henry vs turk chocolate
[16:37:20] <zeeshan|2> both are chocolate, but one is completely shit
[16:37:26] * zeeshan|2 ends troll mode
[16:38:32] <fluffybitchx> I think he's confusing a MOV with a TVS. I have a box of old transorbs somewhere...
[16:40:02] <bobo_> you may be correct transorbs
[16:42:27] <bobo_> when they first came out , they were red on outside and exploded a lot
[16:44:53] <fluffybitchx> anything that has to disspiate a large amount of energy in a hury is prone to that.
[16:45:05] <fluffybitchx> hurry
[16:45:15] <zeeshan|2> well this mov is oversized
[16:45:20] <zeeshan|2> it was the biggest body one i could find
[16:48:55] <bobo_> got the lub pump and lub lines hooked up ? or still wating on those dumb fittings ?
[16:49:25] <fluffybitchx> meh. I should be grinding shafts, but I'm tired, and a nap sounds much nicer...
[16:50:14] <zeeshan|2> bobo_: still waiting o n them
[16:50:16] <zeeshan|2> im gonna nap
[16:50:19] <zeeshan|2> i woke up way too early today
[16:50:23] <zeeshan|2> :D
[16:50:27] <fluffybitchx> 4am here. heh.
[16:52:20] <Tom_itx> yeah that's two of us
[16:56:52] <PetefromTn_> _methods hey man ya there?
[16:56:57] <_methods> yo
[16:57:16] <Tom_itx> i wonder if a 1N914 would work across a 5v relay coil?
[16:57:18] <PetefromTn_> Jeez man I could give you a big freakin' sloppy kiss for this idea
[16:57:22] <_methods> hahahhaha
[16:57:24] <Tom_itx> or if that's too lightweight
[16:57:30] <PetefromTn_> I probably would have never thought of using the router
[16:57:36] <_methods> well glad i could be useful somehow lol
[16:57:40] <PetefromTn_> and it is not only making this go WAY faster
[16:57:44] <_methods> yeah works ok on alum
[16:57:51] <_methods> LOUD
[16:57:53] <_methods> but it works
[16:57:54] <PetefromTn_> but it is allowing me to make an equal champfer on both sides perfectly
[16:58:07] <PetefromTn_> meh the cut is so slight it is not really any louder than the router itself...
[16:58:16] <PetefromTn_> I can't thank you enough my friend....
[16:58:22] <_methods> oh yeah if you try and do a heavy chamfer it's loud
[16:58:24] <_methods> np man
[16:58:29] <PetefromTn_> I was NOT looking forward to doing this with the whirlygig
[16:58:36] <_methods> hope you make some more money this way
[16:59:00] <_methods> get your lathe going
[16:59:02] <PetefromTn_> well hell yeah if it takes less time and makes the parts look better it is definintely going to help
[16:59:12] <PetefromTn_> YOU DA MAN!!!
[16:59:17] <PetefromTn_> ;)
[16:59:49] <PetefromTn_> I can finish one of these things on both sides now in under a minute and it looks as good as if I had run it on the machine
[16:59:54] <_methods> you use a pilot bearing bit?
[16:59:58] <PetefromTn_> yeah
[17:00:01] <_methods> cool
[17:00:17] <PetefromTn_> I have a little quarter inch 90 degree champfer bit I used for woodworking
[17:00:22] <_methods> yeah
[17:00:24] <_methods> perfect
[17:00:37] <PetefromTn_> It just barely has enough room under the bearing to make the champfer exactly how I would have wanted it.
[17:00:56] <PetefromTn_> It's a beautiful thing man..
[17:01:04] <_methods> hahah well good deal
[17:02:15] <PetefromTn_> I need to rig up some kinda blower to blow the tiny chips away so they don't get caught under the part while I am doing it and kinda scratch it. These are getting a brushed finish anyways but I want to avoid it as much as possible.
[17:02:25] <_methods> heh if you do one side in the machine you'll only have to do one side with the router
[17:02:44] <PetefromTn_> naah this is way faster
[17:02:53] <PetefromTn_> and saves me a toolchange during the program
[17:02:56] <_methods> heheh
[17:02:57] <_methods> right
[17:03:04] <_methods> oh yeah i forgot tool changer
[17:03:16] <PetefromTn_> if I had known it would be this easy I would have been doing it during the program runs
[17:03:37] <_methods> well hopefully you'll get the job again
[17:03:47] <PetefromTn_> I know I must sound like a wanker here but I really appreciate the idea and I will be doing it from now on on similar jobs.
[17:04:05] <PetefromTn_> yeah I am sure once they see these they will want to buy more when they run out hopefully. They look really cool.
[17:04:06] <Tom_itx> wanker
[17:04:10] <_methods> hahahah
[17:04:20] <Tom_itx> :D
[17:04:40] <PetefromTn_> :D
[17:04:55] <PetefromTn_> You just saved my bacon from a bunch of hand work
[17:05:11] <_methods> thank god i hate scut work
[17:05:15] <_methods> especially deburring
[17:05:37] <PetefromTn_> yeah me too...little stuff like holes I kinda enjoy doing while the next part is running
[17:05:50] <PetefromTn_> but the whole part both sides like this would have been no fun at all
[17:06:45] <_methods> i'll do anything to avoid manually deburring
[17:06:46] <PetefromTn_> I figured I was actually going to use a deburring wheel on a bench grinder but after using a die grinder by hand and with a loc pad made from red pad it was not looking that nice really
[17:06:51] <_methods> can't stand it
[17:07:18] <PetefromTn_> this is so much easier it is not even funny
[17:07:30] <PetefromTn_> I have a large plywood base plate I made for my router
[17:07:41] <PetefromTn_> clamped upside down on the workbench
[17:07:50] <PetefromTn_> it is kind of like a little router table
[17:07:54] <_methods> ahh you just made it a router table
[17:07:55] <_methods> yeah
[17:08:01] <_methods> good idea
[17:08:05] <PetefromTn_> and I just stuck the bit in there and can move the parts quickly and easily
[17:08:09] <_methods> that will be way more consistent
[17:08:09] <PetefromTn_> yeah
[17:08:16] <PetefromTn_> it is SO consistent
[17:08:18] <PetefromTn_> and fast
[17:08:31] <_methods> now that is a good idea
[17:08:38] <PetefromTn_> I should be done with all of these damn parts this evening for sure now...
[17:08:42] <PetefromTn_> WOOHOOooo
[17:09:38] <PetefromTn_> so again my thanks I am gonna get back to it here... talk later guys!
[17:10:49] <PetefromTn_> Oh wait are they launching the space X rocket here in a bit or did I miss it?
[17:11:53] <_methods> hahahha605
[17:11:54] <_methods> oops
[17:11:58] <_methods> 605 est i think
[17:12:12] <_methods> 1805 EST
[17:12:13] <PetefromTn_> yeah that is in like ten minutes
[17:12:39] <PetefromTn_> http://www.spacex.com/webcast/
[17:13:36] <PetefromTn_> T minus 13 minutes
[17:15:00] <PetefromTn_> well apparently high altitude winds were too high so they scrubbed the launch again.
[17:15:42] <_methods> damn
[17:15:56] <PetefromTn_> they're gonna try again tomorrow
[17:38:26] <tjb1> PetefromTn_: any pictures of these sexy parts?
[17:56:57] <fluffybitchx> yay/meh. yay, I got a bunch of yardwork done. meh, that distracted me from grinding flats.
[18:02:17] <farbro> Hi, I'm gonna build a CNC bottle engraver and I will probably need some kind of pressure control on the Z axis. Is this a common feature among CNC machines? Some kind of mechanical spring solution or force control on the linear motion motor?
[18:03:19] <CaptHindsight> it's not common on machines that cut
[18:05:26] <PCW> Dont engravers often have a shoe that maintains spindle height
[18:05:31] <CaptHindsight> farbro: why do you want to measure the force in the Z axis? are the bottle shapes very irregular?
[18:07:53] <farbro> CaptHindsight: Yes, they are very often not perfectly cylindrical. So the easiest way would be to have the Z axis follow the bottle.
[18:08:22] <CaptHindsight> https://www.ishor.com/images/Images26/26-370.gif mounts the tool using spring pressure
[18:08:33] <CaptHindsight> http://pepetools.com/engraving/horizontal-engraving-machine
[18:09:58] <CaptHindsight> farbro: whats is going to move on your machine, the parts, the tool, some of each?
[18:10:49] <farbro> PCW: Hmm, yeah that's one solution. But it still needs to know how far to push...
[18:11:05] <PetefromTn_> farbro https://www.youtube.com/watch?v=HOiBB3xEphk
[18:12:16] <PetefromTn_> tjb1 working on em right now but I will try to get some finished pictures for ya. I do have this photo I took the other day of three of them just off the Cincinatti.... http://i.imgur.com/uXD5hKe.jpg
[18:12:42] <PetefromTn_> already buzzed thru champfering both sides and the holes in about half of them thanks to methods LOL
[18:15:17] <CaptHindsight> if the depth of the cut is not precision then mounting the spindle on a spring is easiest and lowest cost
[18:15:46] <farbro> CaptHindsight: Ah, yeah springs it is then. My machine doesn't exist yet, it's still in sketching state. :) One solution would be to just have a push/pull solenoid, but if I had a stepper motor and threaded rod instead it would give the machine much more potential than just bottle engraving. So I'm wondering how to combine them in some way
[18:16:16] <CaptHindsight> we print onto irregular surfaces and have to control the distance from the nozzles to the surface to a few microns
[18:16:35] <farbro> PetefromTn_: Ah, interesting video
[18:16:37] <CaptHindsight> we either probe and profile the surface or use a laser micrometer
[18:19:23] <CaptHindsight> http://www.rolanddga.com/products/engravers/egx360/ $18,995 US
[18:20:24] <CaptHindsight> https://www.youtube.com/watch?v=cOMFK2IJuHM Wine Bottle Engraving Machine
[18:21:12] <CaptHindsight> both spring loaded
[18:21:52] <farbro> CaptHindsight: Ok, I'll look into a spring solution then.
[18:22:06] <CaptHindsight> or a 60W laser version
[18:22:15] <CaptHindsight> https://www.youtube.com/watch?v=5w4uQhxpmjo
[18:23:53] <Tom_itx> ok my idea for using these latching relays didn't work
[18:24:12] <farbro> CaptHindsight: Yeah I was thinking about laser but it seems too expensive. I'm looking for a very cheap solution... :)
[18:24:53] <Tom_itx> i thought i might be able to wire on side of the DPDT to feed the 2nd coil to release it but even with a cap on it, it doesn't maintain the voltage long enough to reset the relay
[18:26:17] <Tom_itx> it was kindof a long shot anyway
[18:29:12] <Tom_itx> i might be able to rig some diodes up and make it work but it's hardly worth it
[18:29:35] <renesis> 03:49:54 < PCW> Dont engravers often have a shoe that maintains spindle height
[18:30:00] <renesis> sometimes, my engraving tool holder its a screw on cap so you can set height, dont have it
[18:30:25] <renesis> farbro: i think maybe you are looking for a spring loaded engraving bit holded?
[18:30:28] <renesis> *holder
[18:31:02] <renesis> so you adjust the pressure by either using a stronger spring (or compressing the one you got)
[18:31:51] <renesis> and by how deep youre setting the z (which effectively compresses the spring more if youre not capable of cutting that deep in a single pass due to speed/feed/material)
[18:33:06] <renesis> so if youre doing glass with a diamond cutter, zero speed, you can assume almost no penetration, you can vary the pressure by how far you go into the work and compress the tool holder spring
[18:34:14] <renesis> if youre doing glass with a rotational cutter, you can use z to full depth, make sure it gets that far with a strong enough speed, and a slow enough feed
[18:35:01] <renesis> or you can set z deeper than your intended depth, and then feed fast enough that at your spindle speed it only cuts as deep as you want with a gicen spring
[18:35:33] <renesis> last way is prob faster than 2nd way
[18:37:03] <renesis> correction 2nd way: make sure it gets that far with a strong enough *spring*
[18:39:06] <fluffybitchx> woot! precision angle grinding completed.
[18:39:12] <zeeshan|2> nap completed
[18:39:48] <tjb1> PetefromTn_: what are they?
[18:39:53] * fluffybitchx was more productive
[18:40:14] <zeeshan|2> nap is good
[18:40:17] <zeeshan|2> now i will be more productive
[18:40:23] <zeeshan|2> i can't decide whether i should fix the power supply first
[18:40:26] <farbro> renesis: Hm, yeah that sounds like a plan. I'm trying to find spring loaded tool holders. This is a lightweight machine so it has to be quite small. I was thinking about using a dremel, but not sure...
[18:40:29] <zeeshan|2> or do wiring on the spindle encoder :)
[18:41:01] <fluffybitchx> you should do the thing that makes what you have work, rather than the thing that makes some possible thing in the future maybe work.
[18:41:13] <renesis> farbro: http://www.2linc.com/engraving_mini_1-4.htm
[18:41:24] <zeeshan|2> lol
[18:41:31] <zeeshan|2> but power suplpy repair can be done in the warmth
[18:41:31] <renesis> kinda pricey, thats the smallest they make, i got mine 1/2 price on ebay
[18:41:34] <zeeshan|2> machine is cold right now!
[18:41:49] <fluffybitchx> get a jacket and/or heater? :P
[18:41:54] <CaptHindsight> Price: $345.00 each In Stock well it is turn key
[18:42:14] <renesis> it doesnt include the nosepiece for setting Z
[18:42:46] <renesis> i followed their speed/feed guide for delrin and steel and got great results both times without the noise piece
[18:43:30] <renesis> it doesnt go quite full depth at their recommended rates, lightest spring, so you can do a second path and get bit more definition
[18:43:35] <renesis> comes with 3 springs
[18:43:39] <farbro> fluffybitchx: Yeah I guess it would be better to just focus on this specific task. That will probably make more sense to my examinators too... (this i a school project)
[18:44:28] <farbro> renesis: Cool, way too expensive for this project though...
[18:44:34] <CaptHindsight> farbro: let us know what grade we got in the class :)
[18:45:03] <renesis> farbro: there are cheaper tool holders if you look around, likely import
[18:45:19] <farbro> CaptHindsight: Haha, I'll reference to you in the report ;)
[18:45:33] <renesis> ive been buying little engraving tools from 2L for a long time, for circuit boards, i like them
[18:46:09] <fluffybitchx> farbro: that was intended for zeeshan, but I'm glad it helps you too. lol
[18:46:20] <renesis> i dont think the toolholder price is as fair as their carbide bits, but half off barely used im happy
[18:47:24] <farbro> fluffybitchx: Haha, yeah it really applies
[18:47:44] <farbro> renesis: Hm ok, I'll look closer
[18:55:58] <renesis> farbro: also consider that with a diamond tip into glass you dont have to actually spin the bit
[18:56:15] <renesis> so you dont really need a high speed engraving holder or even a spindle
[18:56:54] <farbro> renesis: You mean just scratch the surface?
[18:56:58] <renesis> yeah
[18:57:30] <renesis> so you could just do a cylinderical bit holder with a spring behind the bit
[18:58:05] <renesis> and some sort of feature to keep the bit from popping out if you are doing discontinuous cutting
[18:58:15] <farbro> renesis: Oh.. never thought about that. But I guess that requires very high accuracy if you need to have a "filled" area
[18:58:29] <renesis> continuous cutting, you can just push the bit in and clip it when not in use during setup
[18:58:49] <renesis> you can hatch the fill area
[18:59:09] <renesis> instead of trying to cut it completely
[19:00:22] <renesis> https://www.youtube.com/watch?v=HOiBB3xEphk
[19:00:25] <farbro> renesis: interesting!
[19:00:32] <renesis> think this guy used engraving fonts
[19:00:57] <farbro> I didn't realise that thing is not rotating
[19:01:05] <renesis> so the solid fill areas are actually made with a bunch of parallel strokes, basically hatching
[19:01:48] <farbro> Hmm, I wonder what precision is required to make the strokes look invisible
[19:01:53] <renesis> yeah i got a diamond bit along with the toolholder, was pretty amazed how easy it was to scribe my pyrex baking dishes
[19:03:25] <XXCoder> nice
[19:03:45] <XXCoder> my shit dermel comes with em too, I do want to try engrave once I ever get router working
[19:03:47] <renesis> if i price the cutters at retail (they look unused), for a 90d conical half round, a 120d conical, ~1/8" 4 flute endmill, and diamond conical bit, i only paid like $100 for the tool holder
[19:04:16] <fluffybitchx> renesis: wouldn't scribing your pyrex create a stress riser that'll make it crack when being used for any of the myriad of temperature-changing tasks pyrex is used for?
[19:04:45] <renesis> its like 3/16" deep and i did a light line
[19:04:49] <renesis> pretty sure itll be fine
[19:04:54] <XXCoder> tet it
[19:04:56] <renesis> ive made bacon at 400F in it since
[19:05:22] <renesis> not like, a lasagna, but seems fine so im not worried
[19:05:34] <fluffybitchx> now dump it in a sink of cold water. :P
[19:05:46] <fluffybitchx> (while it's 400F)
[19:05:51] <renesis> in retrospect, i could have used one of the shitty china art glass pipes i have
[19:06:00] <renesis> chinese boro is still probably boro
[19:06:12] <renesis> i wouldnt do that anyway
[19:06:31] <XXCoder> free explosion
[19:06:46] <renesis> its boro itd be fine at normal oven temps
[19:07:13] <fluffybitchx> "art glass pipes" sounds like marijuana accessories.
[19:07:15] <renesis> still wouldnt do it tho, not a great habit
[19:07:25] <XXCoder> interesting video
[19:07:27] <XXCoder> yours?
[19:07:46] <renesis> yes the art is how we differentiate ourselves from freebase cocaine and crack users
[19:07:52] <farbro> renesis: Ok thanks for the new ideas. I'll get back to you!
[19:07:54] <fluffybitchx> lol
[19:08:04] <renesis> tho shelden black science glass looks a lot like tweaker gear
[19:08:22] <XXCoder> spring loaded bit interesting
[19:08:32] <renesis> the price of asian art glass is pretty disgusting tho
[19:08:41] <XXCoder> I assume cnc path is in normal rod form
[19:09:02] <XXCoder> hard to see, is that ball em?
[19:09:14] <renesis> in the youtube?
[19:09:18] <XXCoder> yeah
[19:09:39] <renesis> just whatever the diamond is set into, prob doesnt have flutes so shape doesnt really matter
[19:09:49] <XXCoder> interesting
[19:10:32] <XXCoder> funny how scale looks like
[19:10:39] <renesis> one i got is set into 120deg conical end
[19:10:43] <XXCoder> it looks like normal cup till you HUGE hands come in lol
[19:10:52] <XXCoder> your
[19:10:59] <renesis> haha, i think thats a sherline rotary
[19:11:24] <renesis> so i knew it was pretty little
[19:14:02] <XXCoder> renesis: http://fatgirlkitchen.typepad.com/.a/6a015394069e98970b0167666ef5d1970b-800wi ;)
[19:16:09] <renesis> ha
[19:16:57] <XXCoder> :)
[19:53:32] <CaptHindsight> http://www.3ders.org/articles/20150210-voltera-v-one-prints-circuit-board-prototypes-in-minutes-launches-on-kickstarter.html
[19:55:10] <CaptHindsight> https://www.kickstarter.com/projects/voltera/voltera-your-circuit-board-prototyping-machine
[19:56:01] <XXCoder> price is high
[19:56:09] <XXCoder> its basically small cnc
[19:56:20] <XXCoder> whats new is head
[19:57:01] <CaptHindsight> it dispenses silver ink and also an insulator for overlapping traces
[19:57:14] <XXCoder> its probably good price
[19:57:17] <XXCoder> think so?
[19:57:27] <XXCoder> *do you
[19:58:45] <CaptHindsight> the dispenser looks like an extruder
[19:59:00] <CaptHindsight> doesn't use compressed air
[19:59:06] <CaptHindsight> that I can see
[19:59:21] <CaptHindsight> https://s3.amazonaws.com/ksr/assets/003/243/859/6acb4b33ae92bd29c226347e2648172e_large.gif?1423241947
[20:00:49] <CaptHindsight> it's silver ink so it's expensive compared to copper
[20:01:19] <CaptHindsight> doesn't do vias, but it does let you print more than one layer
[20:01:30] <CaptHindsight> all on one side
[20:02:03] <CaptHindsight> https://ksr-ugc.imgix.net/assets/003/243/854/47a87192eacd45a07169117177c9a542_original.gif?v=1423241911&w=700&h=&fit=max&q=92&s=03d0406267d9cedb8ffe9b380940dbe0
[20:03:30] <CaptHindsight> a 3-axis mill that size is $400 with controller
[20:04:50] <CaptHindsight> minimum trace 9mil or 200um
[20:05:00] <PCW> wonder how well connectors stay on
[20:05:56] <CaptHindsight> if the connectors have solder tabs that you solder from the opposite side or have locking pins they should be ok
[20:06:21] <CaptHindsight> but SMT connectors, not very well unless you add an adhesive
[20:06:41] <PCW> yeah glue when done
[20:07:22] <CaptHindsight> https://s3.amazonaws.com/ksr/assets/003/244/519/eaada282e5e75d9c052036bac9ee193d_large.png?1423249434 printing the insulator so you can have conductors cross over
[20:07:27] <Tom_itx> do you bake the ink when it's done or does it just dry?
[20:08:01] <CaptHindsight> sintering will always improve the conductivity
[20:08:18] <CaptHindsight> but I don't see it in the specs so far
[20:08:50] <CaptHindsight> I wonder how many silver ink patents they are violating?
[20:09:01] <CaptHindsight> it's another mine field
[20:09:15] <PCW> hybrids have been made this way for a long time (though with screen printing)
[20:09:46] <PCW> I wonder if they have resistive paste
[20:09:54] <Tecan> patents have been loosing ground for years. people just design things till someone complains then change it a bit
[20:10:35] <CaptHindsight> they don't mention resistive paste but thats a no brainer to make
[20:54:06] <zeeshan|2> mosfet replacement fixed it
[20:54:07] <zeeshan|2> :-)!!
[20:54:42] <zeeshan|2> is it okay to put my 200 ohm pull up resistor @ the sensor?
[20:54:47] <zeeshan|2> instead of at the 7i77
[20:55:05] <zeeshan|2> its a bit tight in the 7i77 area :)
[20:57:28] <PetefromTn_> woohoo congrats man... fixed what?
[20:57:43] <zeeshan|2> the burnt supply on the 2 drives that blew
[20:57:54] <zeeshan|2> so i now will have 2 easy back up spares
[20:58:03] <PetefromTn_> sweet
[20:58:14] <zeeshan|2> http://www.ebay.com/itm/Fadal-Cat-40-Tool-changer-Pocket-Inserts-/171136938717?pt=LH_DefaultDomain_0&hash=item27d88e72dd
[20:58:19] <zeeshan|2> do you know what else these are called?
[20:58:23] <zeeshan|2> i have 80 of these
[20:58:31] <zeeshan|2> that came with that tool stuff ibought
[20:58:33] <zeeshan|2> theyre useless to me
[20:59:03] <PetefromTn_> no not really maybe something that goes where the lug is on the cat40 holders?
[20:59:14] <zeeshan|2> i was thinking its something for atc
[20:59:38] <PetefromTn_> yeah that is what I am saying some part for the toolchanger carousel
[20:59:48] <zeeshan|2> yea
[21:00:05] <PetefromTn_> my machine has something similar but it is part of the claw kinda
[21:14:51] <Tom_itx> zeeshan|2 you fixed the drives??
[21:14:55] <zeeshan|2> NO
[21:14:57] <zeeshan|2> er
[21:14:58] <zeeshan|2> no
[21:15:08] <Tom_itx> what did you fix then?
[21:15:23] <zeeshan|2> the power supplies to them
[21:15:28] <Tom_itx> oh
[21:52:59] <anarchos_> can i just hook up a encoder with 0-5v output to a paraport pin?
[21:59:25] <cradek> electrically, probably. can you read it fast enough for that to be useful? depends on its resolution and how fast the axis will move.
[21:59:41] <cradek> calculate the latter before you bother
[22:07:48] <witnit> anarchos_ until i picked up an AnythingI/O I used a rotary encoder w/ parport for a handwheel
[22:08:34] <anarchos_> cool. i was thinking of picking up a cheapo encoder for my stepper motors, just as something to do/learn with
[22:08:52] <witnit> fantastic idea, what kind of steppers you going with?
[22:09:29] <witnit> so, you want to use the encoder as a handwheel to jog the machine?
[22:10:20] <anarchos_> no, i want to do a closed loop system that ferror's if anything goes wrong
[22:10:52] <witnit> oh, well it depends again as cradek says. very important about rpms on the encoder
[22:10:57] <anarchos_> yea
[22:11:22] <anarchos_> happen to know what the max sample rate for a paraport is?
[22:11:33] <witnit> im sure there are other boundaries but not many people do closed loops servo via parport that i know of
[22:12:20] <pcw_home> If you just want to detect stalls, a fairly low resolution encoder will do
[22:14:52] <pcw_home> 100 line would catch a single one pole slip stall
[22:15:32] <anarchos_> yeah
[22:15:44] <fluffybitchx> steppers attached to mill. probably will re-attach them though. realized I should have nuts under the heads...
[22:15:58] <fluffybitchx> s/nuts/washer
[22:16:00] <fluffybitchx> washers
[22:16:04] <fluffybitchx> bleh! /me is too tired to type
[22:16:10] <witnit> you have a lathe to make bushings?
[22:16:21] <pcw_home> and a parallel port could read it up to ~ as fast as most steppers can spin
[22:16:51] <witnit> or just needs nuts?
[22:17:16] <fluffybitchx> I meant washers. I typed the wrong thing. I just need to go to the hardware store and pick some up.
[22:17:18] * fluffybitchx is tired
[22:17:34] <witnit> :) have some hot coco and start a fire
[22:17:53] <PetefromTn_> http://i.imgur.com/90vFER1.jpg ;)
[22:18:15] <witnit> ughhh so are sic! =D
[22:18:54] <witnit> we you able to debur the underside without rechucking those?
[22:19:21] <witnit> were*
[22:19:31] <PetefromTn_> sure did...
[22:19:38] <PetefromTn_> thanks to methods idea
[22:19:45] <witnit> nice, what did he come up with?
[22:19:54] <PetefromTn_> both sides of all of them are completely deburred beautifully
[22:19:57] <fluffybitchx> ummm... hddit?leo? the closest word I can make to that is addicted, but that font sure doesn't look like it...
[22:20:25] <PetefromTn_> that is just a few of them there are a LOT more here
[22:20:38] <PetefromTn_> yeah the word is addicted
[22:20:49] <fluffybitchx> also, what are they? lol
[22:21:41] <PetefromTn_> they are a custom lower intake manifold cover for a mazda motor that you put on there when you are doing work on the engine
[22:21:56] <fluffybitchx> ... you mean the type of thing I usually use an old rag for? :P
[22:22:37] <PetefromTn_> yes exactly just to keep shit from falling into the motor....with some class....and an excuse to advertise my customers shop
[22:23:00] <fluffybitchx> lol
[22:23:29] <fluffybitchx> I've never used anything other than rags or shoptowels for such tasks.
[22:24:15] <fluffybitchx> (or luck.)
[22:24:20] <PetefromTn_> yeah well these guys like to do things nice.... you should see the stuff they build. some serious eye candy if you like tuner cars.
[22:25:08] <witnit> I would imagine if you could make the same think for him but do some prototypes have compartments for bolts and a long area for tools to sit in :)
[22:25:20] <witnit> thing* err i cannot type either
[22:25:39] <witnit> so he has a tray that can lock on top of it
[22:25:46] <fluffybitchx> I like tuner cars, where tuner is defined as tuned, modified, radical engine swaps, and things like that. this definition does not include looking like it should hang around mr.t's neck.
[22:28:41] <fluffybitchx> so you shoved an LS1 in the back seat of a compact car using a marine v-drive? now that's a project! covering in shiny chrome pieces isn't tuning. :)
[22:29:44] <witnit> depends on the customer :), ever seen a spoiler on a car that doesnt deserve it? =D
[22:29:47] <PetefromTn_> they are NOT making poser cars there...LOL
[22:29:59] <witnit> hahahahaha PetefromTn_ you get it tho ahahah
[22:30:03] <PetefromTn_> most of the cars have north of 500 HP and many are closer to 1k
[22:30:04] <XXCoder> Jymmm: https://www.kickstarter.com/projects/elanlee/exploding-kittens/
[22:30:09] <XXCoder> the kitten train keeps going
[22:30:17] <XXCoder> they're trying for 150k supporters
[22:30:22] <XXCoder> among many stuff
[22:30:32] * fluffybitchx finds that project's success very sad
[22:30:35] <Tom_itx> i get a kick outta watching street outlaws
[22:30:41] <fluffybitchx> anyone who ever had hope for the human race... give up.
[22:30:42] <PetefromTn_> I did not design the part but I built it to their specs
[22:30:51] <XXCoder> human is always weird
[22:31:06] <PetefromTn_> so it is what they wanted it to be.
[22:31:18] <Tom_itx> that get you paid
[22:31:21] <PetefromTn_> some of the other projects I am working on for them I am getting a bit more input
[22:31:29] <Jymmm> XXCoder: Well, I guestimated $5.4M
[22:31:29] <PetefromTn_> already got paid
[22:31:44] <witnit> our next president will be an app you can get from googleplay
[22:31:52] <XXCoder> lol
[22:32:15] <XXCoder> I doubt it will get 1000% funded, thats 10 million
[22:32:26] <fluffybitchx> I need to help someone with an engine swap project... his xj12 needs a new ls1....
[22:32:26] <XXCoder> er 100,000% I mean
[22:32:28] <witnit> dood angry birds
[22:32:32] <witnit> anything can happen
[22:33:15] <fluffybitchx> the swap was done a while ago... complete aftermarket ram fuel injection system and other shiny bits... but the motor's spun a rod bearing.
[22:34:53] <fluffybitchx> and I need to finish up my engine swap... got a couple engine codes to get rid of (ecu is bitching I didn't hook up its fan controls, for example), and needs an exhaust fabbed.
[22:34:55] <witnit> does anyone know anything about using nutrunners?
[22:35:01] <fluffybitchx> yes
[22:35:04] <witnit> with cnc
[22:35:06] <fluffybitchx> no
[22:35:07] <witnit> =D
[22:35:21] <XXCoder> Jymmm: they need 3 more "acivements" for next one, and easiest I think is 150,000 backers, youtube songs (x5) and probably 100 person picture, all with cat ears
[22:35:34] <witnit> i was thinking about using them for some projects due to cost but, im unsure of their capabilities
[22:35:50] <fluffybitchx> only nutrunners I have are the type either a skilled union worker and/or a chinese 7 year old uses to manually install fasteners to a set torque.
[22:35:52] <witnit> fluffybitchx, what do you know about their backlash and endplay?
[22:36:10] <fluffybitchx> ... huh? we must be thinking of different kinds of nutrunners.
[22:36:18] <witnit> i was thinking of the programmable kind
[22:36:47] <witnit> but i only ever seen them lying in corners of dark shops
[22:36:58] <fluffybitchx> a nutrunner is a pneumatic tool, often similar in construction to an impact wrench, to rapidly install fasteners to a repeatable torque.
[22:39:17] <witnit> http://www.ebay.com/itm/Atlas-Copco-Model-ETD-DS7-30-10ST-nutrunner-with-cable-used-/291374760877?pt=LH_DefaultDomain_0&hash=item43d74a03ad
[22:39:22] <witnit> something similar to this
[22:39:23] <fluffybitchx> http://www.ingersollrandproducts.com/am-en/products/tools/fastening/air-nutrunners/handheld-nutrunners/adjustable-cushion-clutch-nutrunners/7-series I have the old version of one of those... it's like a cordless screwdriver, but about fifty times faster, and impact so you don't need to fight the torque. :)
[22:40:11] <fluffybitchx> I've never seen an electric one... no idea how they operate.
[22:41:06] <fluffybitchx> if they're just electric drive to a similar impact mechanism, "backlash" is about a turn, endplay and sideplay depend on how worn the bearings are...
[22:41:18] <witnit> I may pick some old ones up and if i can get it running on a mesa card i will sure tell everyone how much I do and dont like them
[22:42:00] <witnit> I will just have to pick some up try things with them
[22:42:15] <fluffybitchx> on the air ones, the torque is set with a mechanical clutch or shutoff mechanism.
[22:42:24] <witnit> I really want them because they are so compact
[22:42:37] <fluffybitchx> what're you planning on using it for?
[22:43:22] <witnit> i have a few machines which i would like to put a live tooling in from the rear at low cost
[22:44:02] <fluffybitchx> eh, might not work well. at least most of the air ones are impact. don't know about the electrics...
[22:44:33] <witnit> http://img.directindustry.com/images_di/photo-g/multi-spindle-drilling-head-26530-3303705.jpg
[22:44:38] <fluffybitchx> and they're usually plain bushes instead of ball as there's no sideloading in normal use
[22:44:40] <witnit> in those holes
[22:45:47] <PetefromTn_> witnit what machines are you speaking of
[22:45:52] <witnit> quick swappable servos units with the tooling and collet preset out side of the machine and you slide the servo and cutting tool out from the rear
[22:45:54] <witnit> davenport
[22:46:31] <witnit> it would be for a stationary head, the picture shows the the revolving side there.
[22:46:39] <witnit> but the part looks similar
[22:48:03] <XXCoder> interesting cncept https://www.kickstarter.com/projects/1703258614/psdr-pocket-hf-sdr-transceiver-with-vna-and-gps
[22:49:51] <PetefromTn_> those screw machines are quite interesting
[22:49:56] <fluffybitchx> why the hell do they start off with a video? I'm not going to play it, and it's the absolutely last way I want to see product information.
[22:50:14] <XXCoder> I dont bother with videos myself
[22:50:15] <PetefromTn_> well you'd be the exception then
[22:50:22] <XXCoder> information is almost always spokenb
[22:50:25] <XXCoder> and not captioned
[22:50:40] <XXCoder> wanna try it? just turn on tv and mute it
[22:50:50] <XXCoder> try to figure whats going on. dont watch your favorite show
[22:51:16] <PetefromTn_> no thanks I will just enjoy a well made video production whenever possible
[22:51:48] <XXCoder> PetefromTn_: basically what I'm saying is that videos is pointless because theres always information in audio that I cannot understand
[22:52:04] <fluffybitchx> it's a radio with no moving parts. video is not going to give any information that can't be provided much better with text and a couple images.
[22:52:44] <PetefromTn_> XXCoder for your instance I can understand it. but there is no way text and pictures can tell a story as well as a well made video
[22:53:20] <XXCoder> well made maybe dunno
[22:53:27] <fluffybitchx> you're right, there's no way text and pictures can be as slow and annoying as listening to someone talk when you could just read it.
[22:53:57] <fluffybitchx> for complex mechanical motions and such, video is an excellent tool. but we're talking a device with no moving parts.
[22:57:29] <fluffybitchx> and, of course, they have the scrolling-breaking position:fixed bar that's so idiotically popular these days.
[23:06:28] <XXCoder> http://consumerist.com/2015/02/09/what-you-say-to-your-samsung-smart-tv-is-transmitted-to-a-third-party/
[23:06:57] <XXCoder> if I was hearing and live alone, I would leave looped recording of some porn 24/7 when not in use
[23:07:08] <fluffybitchx> lol
[23:07:08] <XXCoder> probably make them wonder about my sex life lol
[23:12:01] <witnit> especially if you randomly called out only names of fictional charactors, in a very ..desperate tone
[23:14:04] <fluffybitchx> bbl, wolfy bedtime
[23:15:22] <witnit> i just assume everyone who had a phone and tablet was already doing this same thing just without the consent of a EULA
[23:17:18] <witnit> next time you fart an ad for pepto bismol will pop up on your tv and google adsense will be informing your local cvs to email you a flyer
[23:18:48] <witnit> you will walk into a store, the facial recognition will software will assign your face to an account and your purchase history... the future is scary
