[00:54:44] <CaptHindsight> I might have missed the answer to: How much current is there through a -1 ohm Resistance with 1 Volt applied?
[01:08:16] <Crom> CaptHindsight, 1v thru 1ohm is 1A
[01:08:44] <renesis> wtf is -1 ohm
[01:08:47] <renesis> thats a battery
[01:18:24] <roycroft> it's antielectricity
[01:18:31] <roycroft> positrons flowing through the wire
[01:50:56] <norias> hi
[01:51:10] <Crom> morning norias
[01:51:21] <norias> morning
[01:51:27] <norias> night here, really
[01:51:30] <norias> 2:29am
[01:51:37] <norias> so, morning, i guess
[01:52:53] <Crom> it's a freenode thang... when you show up it's morning, when you leave it's night.. FREENODE standard time
[01:53:50] <norias> fair
[01:54:16] <norias> went on visit to a company called Exone today
[01:54:26] <norias> they make a line of 3d printers for metal
[01:54:36] <norias> and sand (for aluminum casting)
[01:54:39] <norias> neat stuff
[01:54:56] <Crom> nice sintered? or epoxy binding?
[01:55:46] <norias> i'm going to say... uh. sintered
[01:56:16] <Crom> sintered is laser melts particles together
[01:56:33] <norias> well, so these parts get sintered in an oven
[01:56:56] <norias> powder held together with binder
[01:57:01] <norias> binder gets cooked out in oven
[01:57:20] <norias> so, a bit like traditional powdered metal in that sense
[01:57:31] <Crom> expoxy then... using a inkjet type spray nozzle
[01:57:42] <norias> right
[01:57:59] <norias> sounds like off terminology to me
[01:58:04] <norias> since the parts do get sintered
[01:58:10] <norias> just not with a laser
[02:00:10] <Crom> ones I've seen you take the expoxied model, stick it in an oven and you heat it up and draw in a solder/bronze type material which is wicked up into the porous model
[02:00:35] <norias> right
[02:00:47] <norias> at that stage of the game
[02:00:54] <norias> it's the same thing as powdered metal process
[02:01:14] <norias> really, it is a powdered metal process
[02:01:23] <norias> just a different way to get there with binder, etc
[02:02:18] <Crom> sintered is a laser causes the powder to barely melt and stick together. no binder.
[02:02:45] <norias> that's not the only way to sinter
[02:02:53] <Crom> you can then place it into an oven and wick in the solder/bronze to fill the voids
[02:04:23] <Crom> ruger would make the MKI using sintered melted powder then heat it to melt together in a ceramic mold
[02:05:39] <norias> yeah
[02:05:50] <norias> i used to work in a place that did the same thing
[02:05:56] <norias> but with tungsten carbide
[02:06:17] <norias> you do it in a HIP furnace
[02:06:24] <norias> argon gas under pressure
[02:06:58] <norias> sometimes the preforms are done in compacting dies
[02:07:27] <norias> we machined the preforms before they got sintered
[02:07:35] <norias> which was a bit of a delicate process
[02:07:44] <norias> they used a wax of some sort as the binder
[02:08:38] <norias> i think it was cold isostatic pressing
[02:08:52] <norias> of maybe 6-7 generic forms
[02:09:05] <norias> which we machined to near neat (plus shrink factor)
[02:09:08] <Crom> true. but the 3d laser metal sintered items can get to around a 95% material density. Expoxy binder material gets up to around 92% density from my understanding
[02:09:16] <norias> then they went in the HIP
[02:09:28] <norias> sure
[02:09:39] <norias> after 90% ish density
[02:09:41] <Deejay> moin
[02:09:47] <norias> the difference is kinda academic
[02:10:05] <norias> you don't _have_ to fill with bronze
[02:10:14] <norias> you can leave it porous
[02:10:33] <norias> and in industrial applications they do, unless you need it to be air/water tight
[02:10:57] <norias> density is also partially controlled by material
[02:11:03] <Crom> true... I'd rather fill with bronze, makes it alot more ductal
[02:11:24] <norias> hmm. does it really?
[02:11:45] <norias> at that point it's a matrix who's ductility is mostly controlled by the bulk material
[02:12:00] <norias> Wc is that way
[02:12:16] <norias> it's a matrix of tungsten and either cobalt or ...
[02:12:23] <norias> dang, i forget
[02:12:34] <norias> nickel
[02:14:13] <Crom> yepI'm thinking stainless or carbon steel. bronze infill reduces quite a bit of the snappiness um.. what's the word
[02:14:37] <Crom> not crystaline
[02:15:37] <norias> lower hardness
[02:15:41] <norias> higher toughness
[02:16:05] <norias> although, i don't think the increase in toughness is necessarily...
[02:16:12] <norias> the normal mechanism
[02:16:20] <norias> but i'm not totally sure there
[02:18:11] <Crom> like a M1911 slide. straight sintered works well for .45acp, you probably want infiltration on a .45 win mag slide
[02:22:08] <norias> well, shit
[02:22:17] <norias> i didn't realize protolabs was a listed company
[06:34:36] <Swapper_> anyone here have a power drabar that uses a impact wrench ? my questions is if a break is needed on the spindle to use that to loosen/tighten the drawbar
[06:35:06] <Swapper_> or does the inertia of the spindle suffice to get it off
[07:01:04] <lottefang> Hello linuxcnc community !
[07:02:53] <lottefang> Could any one explain why linuxcnc has both acceleration/deceleration mechanism in control.c and stepgen.c?
[07:03:39] <archivist_herron> because its needed for any mechanical system to avoid overshoot
[07:04:37] <pcw_home> and the stepgen component can be used independetly of motion
[07:10:54] <lottefang> Well then, where is the keypoint to let the stepgen component run under the control.c's way?
[07:13:24] <MarkusBec> i think its because you dont need stepgen to control the cnc
[07:13:53] <pcw_home> typically if something outside the stepgen limits accel you either disable accel limits in the stepgen (accel=0)
[07:13:54] <pcw_home> or set the stepgen accel to say 20% higher than the maximum commanded accel
[07:14:12] <MarkusBec> and you can use stepgen for other purposes than move the cnc
[07:14:46] <pcw_home> a torch height control is one example
[07:21:17] <lottefang> Thanks guys! I thinks i understand now.
[07:23:57] <pcw_home> Its arguable the velocity /accel limits should not be in the stepgen but
[07:23:59] <pcw_home> instead use the limit2 or limit3 comp in those cases where the stepgen is
[07:24:00] <pcw_home> not used with the TP
[07:25:20] <pcw_home> but its tedious to string all those hal comp beads together for common ops
[07:30:43] <skunkworks> there is a fine line between flexablility and unusabillity
[07:30:48] <Jymmm> Mesa and linuxcnc totally useless... https://play.google.com/store/apps/details?id=net.sourceforge.arduinocnccontroller
[07:31:52] <Jymmm> skunkworks: sexy gymnast with a muscle crap?
[07:32:06] <Jymmm> cramp*
[07:35:32] <Jymmm> I really like this part "Works on tablets only 1 core, but really if the tablet is faster mill moving faster, so it is recommended that have 4 cores."
[07:39:15] <Tom_itx> Jymmm did you contribute to it's 4.0 rating?
[07:39:51] <Jymmm> Tom_itx: haha, nope.
[07:40:50] <Tom_itx> i bet it was designed by some reprapper
[07:45:17] <_methods> heheh
[07:46:05] <_methods> they did invent CNC so it would only make sense that they would make this major improvement for mankind
[07:46:53] <_methods> now that they've mastered the world of additive manufcaturing they're setting the sights of their revolution on the ancient art of subtractive manufacturing
[07:47:19] <Tom_itx> it's good to see them pushing the boundaries with technology but i just can't see me plugging my android into a 5 ton hunk of steel swinging around the room
[07:49:33] <Tom_itx> i'm sure midway thru, google would decide to do an update on it too
[07:49:41] <_methods> lol
[07:50:24] <Tom_itx> these toys aren't ours, we're just borrowing them for a fee
[07:51:18] <Jymmm> Tom_itx: midway upgrade, that's stupid! <popup ad goes here>
[07:52:10] <_methods> nice big ad over your program
[07:53:03] <_methods> when you get a phone call your cnc dives into the table
[07:53:19] <Jymmm> but only to the beat of the ringtone
[07:54:50] * Tom_itx pictures some LOUD rap ringone
[07:55:49] <_methods> hahaha
[07:55:52] <_methods> crashstep
[07:57:24] <Jymmm> Hmmm https://play.google.com/store/apps/details?id=de.fastnc.android.cnctoolsplus
[08:29:52] <shaun413> hello
[08:30:03] <shaun413> anyone here have 3d printed a dust collector?
[08:31:00] <furrywolf> I think the vast majority of things people 3D print end up collecting dust.
[08:32:33] <shaun413> ha
[08:32:44] <shaun413> i mean for a cnc
[08:32:48] <shaun413> mill
[08:34:48] <furrywolf> I'm not sure which part you plan on 3d printing... you're sure not printing an electric motor and impeller, a collection bag/barrel, flexible tubing,...
[08:35:26] <shaun413> no, just a mount by the spindle
[08:35:30] <shaun413> to connect to a shopvac
[08:35:46] <furrywolf> should be quite doable, then.
[08:35:52] <shaun413> ok
[08:35:58] <shaun413> anything i should reference?
[08:36:15] <furrywolf> dunno. I've never done 3d printing, nor milling machine dust collecting.
[08:36:24] <shaun413> a dust shoe perhaps?
[08:36:34] <furrywolf> only dust collector I have is for the planer, and it's a 2hp thing with 4" tubing. :)
[08:36:48] <shaun413> im cutting carbon fiber
[08:52:44] <MrFluffy> have you looked on thingiverse?
[08:53:48] <MrFluffy> try vac as a keyword, theres loads it seems
[08:54:12] <shaun413> hm
[08:54:16] <MrFluffy> eg http://www.thingiverse.com/thing:200583
[08:54:25] <shaun413> i could also route one fro acryllic..
[08:54:27] <MrFluffy> print it in ninjaflex and less issue with collisions then
[08:54:50] <MrFluffy> I have a ninjaflex fan shroud on my printer, and it flexes away if theres a collision
[08:55:11] <shaun413> good idea
[08:56:23] <shaun413> i think im going to do my firts cut on the router today..
[08:56:40] <furrywolf> I usually clean up dust/swarf by letting it build up into a big mound around the machine until I start losing tools/parts in it and get annoyed and get out the shopvac...
[08:57:18] <shaun413> can you create gcode in mach3?
[08:57:45] <furrywolf> why are you asking here about mach3?
[08:57:56] <shaun413> is there a mach3 channel?
[08:58:26] <furrywolf> #mach3 is registered according to chanserv, but that doesn't mean there's anyone in it.
[08:58:33] <_methods> not good to leave chips in the cut
[08:58:39] <_methods> your tooling has to recut all that
[08:59:01] <_methods> causes excessive tool wear
[08:59:02] <shaun413> true
[09:01:10] <furrywolf> I might add air blast to my mill one of these years... but all cnc projects, and anything else fun in general, is indefinitely on hold now.
[09:01:53] <_methods> you can make a mister/airblast pretty easy
[09:02:28] <furrywolf> right now I can't make anything
[09:02:32] <shaun413> hm
[09:02:32] <_methods> http://www.cnccookbook.com/CCMillCoolantMister.htm
[09:02:47] <_methods> you can do it from cheap fittings and stuff
[09:03:42] <shaun413> whats a good software to create gcode
[09:03:48] <shaun413> from a dxf or stl
[09:03:53] <furrywolf> right now I can't make _anything_, and that includes making food or making my bed. can hardly fucking move.
[09:04:31] <shaun413> cambam?
[09:13:26] <shaun413> what do you all use to generate gcode?
[09:14:41] <archivist_herron> inside rear of skull
[09:19:44] <Tom_itx> i use cad cam software
[09:20:56] <shaun413> is it free?
[09:25:15] <mk0> HI all
[09:25:42] <mk0> i got stuck with "base linuxcnc2.5" on lucid
[09:25:42] <Tom_itx> if 6k is free yes
[09:26:12] <mk0> is it possible to install 2.6?
[09:26:20] <Tom_itx> follow the update path
[09:26:27] <Tom_itx> you can run 2.7 on it too
[09:27:36] <Tom_itx> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?UpdatingTo2.6
[09:27:40] <shaun413> Tom_itx, let me guess SW and HSMcam?
[09:27:44] <Tom_itx> easy peasy
[09:27:57] <Tom_itx> shaun413, no.. smartcam
[09:28:14] <shaun413> oh
[09:28:26] <shaun413> cambam and meshcam good to try for a pleb?
[09:28:29] <mk0> deb http://linuxcnc.org/ lucid base 2.6 - synaptic says no go
[09:28:34] <Tom_itx> solidworks would work though
[09:28:57] <Tom_itx> i'm looking at Catia right now
[09:29:00] <shaun413> i do have solidworks
[09:29:04] <shaun413> is there a cam software?
[09:29:12] <Tom_itx> of course
[09:29:27] <shaun413> hsmcam says they will contact you
[09:29:32] <shaun413> mah, dont want that
[09:29:33] <mk0> Failed to fetch http://www.linuxcnc.org/dists/lucid/Release Unable to find expected entry deb/binary-i386/Packages in Meta-index file (malformed Release file?)
[09:29:49] <Tom_itx> they don't want to scare you off with the price
[09:29:56] <shaun413> its free
[09:30:02] <shaun413> with sw
[09:30:14] <shaun413> but you need to register for it, and they will audit your info
[09:30:24] <Tom_itx> ok
[09:30:32] <shaun413> not doing that lol
[09:30:44] <Tom_itx> if it's legit then np
[09:30:55] <shaun413> i dont want people auditing my info
[09:31:08] <Tom_itx> that's the cost of free
[09:31:15] <shaun413> mah
[09:32:36] <Tom_itx> mk0 did you refresh?
[09:32:45] <Tom_itx> and uncheck 2.5
[09:32:56] <mk0> Tom_itx, yes!
[09:33:02] <mk0> yes!
[09:33:13] <Tom_itx> that's how i did it
[09:35:37] <Tom_itx> http://linuxcnc.org/docs/devel/html/getting-started/index.html#_upgrade_to_the_new_version
[09:35:51] <Tom_itx> once you get 2.6 then you can update to 2.7 if you like
[09:36:03] <Tom_itx> don't skip 2.6 though
[09:41:38] <CaptHindsight> Crom: certainly, but that wasn't the question
[09:42:25] <CaptHindsight> renesis: do some devices have negative resistance? and is it really negative resistance?
[09:43:35] <CaptHindsight> https://en.wikipedia.org/?title=Negative_resistance
[09:46:39] <CaptHindsight> norias: did they happen to tell you which printheads they use?
[09:47:05] <norias> no, they didn't
[09:49:42] <CaptHindsight> norias: since MIT still holds a valid patent on printing a binder onto sand or powder those printers will stay slow and pricey for years to come
[09:50:16] <norias> MIT licenses
[09:50:22] <CaptHindsight> heh
[09:55:54] <shaun413> what do i set tool diamter to?
[09:56:05] <Tom_itx> the tool diameter
[09:56:14] <shaun413> can i measure it?
[09:56:27] <Tom_itx> i'm not sure, can you?
[09:56:37] <shaun413> idk, where would i measure?
[09:57:00] <CaptHindsight> norias: looks like Dimatix http://www.exone.com/portals/0/ResourceCenter/BinderJetting/ExOne-What-is-Binder-Jetting.jpg that's why they are so slow
[09:57:00] <Tom_itx> the part that cuts the material?
[09:57:42] <CaptHindsight> http://www.exone.com/Resources/Technology-Overview/What-is-Binder-Jetting
[09:57:58] <norias> CaptHindSight: sounds like you know a whole lot more about it than me
[09:59:09] <CaptHindsight> norias: I've been working with inkjet heads for several years. I was just curious about what heads they use.
[09:59:21] <norias> hmm, right on
[10:00:06] <CaptHindsight> Inkjet is one of the most paranoid, controlling, NDA madness, secretive industries there is
[10:00:34] <CaptHindsight> I'm actually surprise that they posted a picture of the heads
[10:01:23] <shaun413> the tip ?
[10:02:42] <norias> huh.
[10:02:54] <shaun413> what do i measure for tool diameter?
[10:02:57] <DaPeace> hey guys, short question.. i want to scale a value from an gmoccapy-pin. think that is not really gmoccapy-specific. any hint what i need for that?
[10:03:25] <Tom_itx> shaun413 the part that cuts the material?
[10:03:34] <shaun413> its needlepointed
[10:03:56] <Tom_itx> enter a small number then
[10:04:05] <Tom_itx> for engraving?
[10:04:05] <shaun413> hm
[10:04:17] <shaun413> oh, Should i not use that bit, im trying to cut foam
[10:04:36] <Tom_itx> probably not
[10:04:37] <norias> this is going to take cofee
[10:04:48] <shaun413> ok theres one that looks like a drill bit
[10:04:49] * norias walks down the stairs.
[10:07:41] <renesis> capthindsight: Therefore, there is no real "negative resistor" analogous to a positive resistor, which has a constant negative resistance over an arbitrarily wide range of current.
[10:07:49] <renesis> from your link
[10:08:51] <norias> waking up is hard to do
[10:09:18] <pcw_home> there are no positive resistances over arbitrarily wide ranges of current either
[10:10:35] <renesis> look man i can buy a resistor with positive values at digikey
[10:10:41] <renesis> i cant buy them in negative values
[10:11:03] <renesis> maybe they are just out of stock, but that still means they dont exist
[10:11:06] <CaptHindsight> renesis: it just open up an interesting discussion since they chose "negative resistance" as the name for the effect
[10:11:19] <CaptHindsight> open/opens
[10:11:33] <pcw_home> no but you can buy a neon bulb that exhibits negative resistance
[10:11:40] <renesis> a lot of circuits have negative resistance properties
[10:12:09] <pcw_home> or even single devices
[10:12:58] <renesis> dont you have to like, spark a neon bulb off?
[10:13:42] <renesis> its not like you put a psu and a resistor and all of a sudden voltage across the resistor reverses
[10:13:47] <CaptHindsight> _methods: on another note investors have filed suit against 3D systems for inflating their forecasts on sales and profits
[10:13:55] <CaptHindsight> the great hype machines
[10:13:56] <renesis> hmm actually i think in some cases it does
[10:14:09] <pcw_home> if you run a neon bulb from a constant current supply the higher the current, the lower the voltage drop across the bulb
[10:14:21] <t12> 3d printing... pure enthusiasm
[10:14:24] <pcw_home> = negative resistance
[10:14:34] <furrywolf> you can buy positive resistances for any current you want, as long as you don't mind a reduction in duty cycle.
[10:14:52] <CaptHindsight> http://3dprintingindustry.com/2015/06/16/investors-seek-class-action-lawsuit-against-3d-systems-for-weak-earnings/
[10:14:53] <renesis> right but i think that has to do with the lowered resistance due to the larger arc
[10:15:04] <pcw_home> well HV breakdone is possible
[10:15:17] <t12> wait till someone does the math on makerbot
[10:15:18] <renesis> i thought thats how they worke?
[10:15:23] <t12> wasnt it about a 500m buyout
[10:15:40] <CaptHindsight> t12: those were still actually selling
[10:15:41] <renesis> you overcome the gas resistance, start an arc, and the plasma is a lower resistance
[10:15:48] <renesis> im just guessing tho
[10:15:52] <CaptHindsight> since they are low cost
[10:16:23] <pcw_home> no you can plot the voltage vs current and you get a negative slope
[10:16:58] <renesis> right because more current is a bigger arc is less resistance is less voltage
[10:17:05] <norias> what about this?
[10:17:06] <norias> http://www.boxzy.com/
[10:17:14] <renesis> the voltage reverses polarity?
[10:17:22] <shaun413> how on earth do i use these hold down clamps?
[10:17:29] <pcw_home> not just bigger (in fact it may get smaller)
[10:17:54] <shaun413> http://g04.s.alicdn.com/kf/HTB1AAPqGFXXXXckXVXXq6xXFXXX6/206231472/HTB1AAPqGFXXXXckXVXXq6xXFXXX6.jpg
[10:18:00] * furrywolf notes designing things that are stable with negative resistances is often fun
[10:18:02] <shaun413> the ones on the bottom of this pic, how do i use these?
[10:18:22] <renesis> pcw_home: yeah i imagine its a weird feedback loop and changes with temp, shrug
[10:18:31] <renesis> a battery is a negative resistance
[10:18:32] <pcw_home> negative resistance without a equal or greater positive resistance makes an oscillator
[10:18:37] <malcom2073_> shaun413: You bolt things down with them
[10:18:49] <shaun413> how malcom2073_ ?
[10:18:51] <malcom2073_> shaun413: Play with them until you figure out a way that works, there are only so many ways you can use them
[10:19:11] <pcw_home> (maybe only one cycle if you dont limit the current)
[10:19:16] <malcom2073_> You put a bolt through the hole, screw it into a nut on your table, and put the piece under it?
[10:19:16] <shaun413> ive tried for 30 mins
[10:19:20] <renesis> pcw_home: right i dont really trust their osillator and positive feedback examples because from the power sources point of view, its still varying positive resistance
[10:19:34] <shaun413> yeah malcom2073_ it wont tighten enough to clamp if i do that
[10:19:47] <malcom2073_> shaun413: The bolts break if you tighten more?
[10:19:50] <renesis> from the input of the circuit, ya its negative resistance, but thats not the whole system
[10:19:54] <malcom2073_> What do you mean won't tighten enough?
[10:19:56] <furrywolf> those are best used with step blocks. if you don't have step blocks, use random spacers.
[10:19:59] <shaun413> they hit the bottom
[10:20:16] <furrywolf> also, that's the most piss-poor accessory kit I've ever seen.
[10:20:23] <malcom2073_> Use washers on the bolts so they don't hit bottom
[10:20:26] <shaun413> step blocks?
[10:20:38] <malcom2073_> shaun413: I hope your work didn't pay more than $900 for that thing
[10:20:46] <furrywolf> pot metal wrenches, holddowns with insufficient parts,...
[10:20:51] <shaun413> idk what they paid malcom2073_ its shit
[10:20:52] <norias> ?
[10:21:06] <norias> what are we talking about?
[10:21:24] <norias> i feel like i totally missed something
[10:21:28] <shaun413> malcom2073_, http://www.tools-super.com/images/l/201212/13566769521.jpg
[10:21:33] <shaun413> its this one or type
[10:21:54] <norias> maybe i just need more coffee
[10:22:16] <malcom2073_> Lol yeah, that's one of them 6040's
[10:22:20] <shaun413> yes
[10:22:35] <malcom2073_> The control systems are total shit on them
[10:22:40] <malcom2073_> As are the bearings
[10:22:44] <shaun413> yep i can tell
[10:22:46] <malcom2073_> And spindles
[10:22:56] <shaun413> :p
[10:22:56] <malcom2073_> But it makes an alright wood/plastic cutting machine
[10:22:59] <furrywolf> shaun413: to use those clamps, use a spacer of the same thickness as your material on the other side of the clamp, and stack washers (or washer-like things like oversized nuts) under the head of the bolt so it doesn't tighten into the bottom of the t-slot.
[10:23:01] <shaun413> shouldnt gottan a probotix
[10:23:13] <shaun413> malcom2073_, im trying to cut CF
[10:23:25] <malcom2073_> shaun413: You'll destroy that machine in notime without a dust system
[10:23:36] <shaun413> they want me to print one
[10:23:37] <shaun413> LOL
[10:23:40] <shaun413> ok
[10:24:09] <furrywolf> http://www.robotshop.com/media/files/images/sherline-step-block-hold-down-set-large.jpg less crap sets (that is, any one costing more than $10) include step blocks, which take the place of having to find spacers of the right height, and a variety of bolt/stud lengths, so you don't need to stack washers.
[10:24:14] <shaun413> furrywolf, i would if i had washers and nuts...
[10:24:38] <furrywolf> if you don't have a random assortment of washers and nuts, you're not qualified to operate a milling machine.
[10:24:38] <shaun413> im about to duct tape the foam down...
[10:24:45] <shaun413> furrywolf, its not my machine
[10:25:10] <malcom2073_> His comment has nothing to do with who owns the machine
[10:25:32] <_methods> i'm pretty sure you're plenty of nuts
[10:25:41] <shaun413> probably
[10:25:46] <shaun413> malcom2073_, they have NOTHING here
[10:25:49] <shaun413> so
[10:26:01] <malcom2073_> So... you should probably fix that.
[10:26:04] <shaun413> lol
[10:26:11] <_methods> 3d print some
[10:26:14] <furrywolf> http://www.mini-lathe.com/Mini_mill/Accessories/Holding/cs03.jpg there's how you set up the non-crap version. since you have the crap version, replace the nice step block with a scrap of something.
[10:26:15] <shaun413> can I literally just duct tape it down for now?
[10:26:25] <malcom2073_> You could hold it down with your fingers
[10:26:27] <malcom2073_> doesn't make it smart or safe
[10:26:30] <_methods> or your face
[10:26:41] <shaun413> http://www.thingiverse.com/thing:6062
[10:26:48] <shaun413> its foamboard malcom2073_
[10:26:54] <norias> hold it down with your face
[10:26:57] <furrywolf> also, if you want more help, install linuxcnc already.
[10:27:00] <malcom2073_> shaun413: I know it's foamboard
[10:27:38] <shaun413> i wish i could furrywolf
[10:27:51] <shaun413> i cant run it on my laptop because i dont have the serial ports
[10:28:02] <malcom2073_> Linuxcnc needs parallel ports, not serial ports
[10:28:08] <shaun413> parallel thats what i mean
[10:28:34] <malcom2073_> So get your work to buy a proper control PC with a parallel port
[10:28:49] <malcom2073_> Wait, you're running mach3, wipe that machine and put linuxcnc on it
[10:28:49] <shaun413> they have one running xp
[10:29:02] <shaun413> its the guys personal machine..
[10:29:04] <shaun413> and mill
[10:29:27] <norias> i pretty much bought a machine for linuxcnc
[10:29:30] <norias> for about $100
[10:29:37] <malcom2073_> Then tell him he needs to wipe it and let you put linuxcnc on it
[10:29:41] <shaun413> could prob us an rpi..
[10:29:43] <shaun413> use
[10:29:49] <malcom2073_> No, you could probably not.
[10:29:52] <shaun413> oh
[10:30:02] <shaun413> malcom2073_, why is that needed?
[10:30:09] <malcom2073_> shaun413: What, linuxcnc?
[10:30:10] <shaun413> how to convince him :p
[10:30:15] <malcom2073_> Because this is a linuxcnc channel
[10:30:18] <shaun413> fright
[10:31:22] <furrywolf> I know! I'll take my ford to the chevy dealer and keep asing their parts guys for help.
[10:33:04] <norias> you'd have trouble with that
[10:33:17] <Tom_itx> furrywolf they probably could help you
[10:33:17] <norias> unlike at ford dealerships
[10:33:26] <norias> most chevy parts guys are only part time
[10:33:38] <Tom_itx> i bet half of em drive chevys anyway
[10:33:42] <malcom2073_> Hard to employ them full time if the parts never break :P
[10:33:54] <Tom_itx> good point
[10:34:06] <furrywolf> most chevy parts guys probably know fords are superior anyway...
[10:34:27] <norias> superior boat anchors
[10:34:36] <furrywolf> they just needed a job. it's like working at mcdonalds. you don't want to, you boss sucks, and your product is crap, but you need a paycheck...
[10:34:48] <norias> superior at keeping parts guys and mechanics in a paycheck
[10:35:06] <Tom_itx> better job security working in a ford parts dept
[10:35:28] <furrywolf> only because chevies are such crap they just crush them into little cubes instead of fix them.
[10:35:48] <Tom_itx> and i thought you were a subaru fan
[10:36:20] <furrywolf> subarus don't need parts. :)
[10:37:11] <malcom2073_> Yours does...
[10:37:13] <malcom2073_> (too soon?) :-P
[10:37:14] <Tom_itx> i haul my smart car around in my cheby PU
[10:37:28] <Tom_itx> jk..
[10:37:32] <Vikingsraven> hi guys, posted yesterday as mrk-s weanting some help on qjoypad but network dropped out, im having a few issues. Its installed using the process on the linux cnc wiki, but if i tru to run it it coems up with and error about symbol incorrect any ideas on how to fix it please im using 10.4 ubuntu and i believe the latest qjoypad
[10:37:43] <furrywolf> my subie is beyond needing parts. :(
[10:38:33] <furrywolf> I'm going to have to work really hard to get the insurance company to pay anything close to what I have into that car.
[10:38:33] <Vikingsraven> god my spellings crap!
[10:38:44] <furrywolf> and your punctuation, too!
[10:38:56] <Vikingsraven> cheers
[10:39:08] <Vikingsraven> ":.,@
[10:39:10] <shaun413> meshcam vs cambam?
[10:39:29] <Tom_itx> no opinion of either
[10:39:40] <Tom_itx> except the 1 day i used cambab i thought it sucked
[10:39:43] <shaun413> can they run on linux?
[10:40:01] <Tom_itx> do they say they can?
[10:40:10] <shaun413> idk
[10:40:11] <Tom_itx> if not then chances are good they don't
[10:40:20] <Tom_itx> do your own homework
[10:40:43] <shaun413> meshcam works in ubuntu
[10:41:05] <Vikingsraven> so any ideas why im getting the symbol error then?
[10:41:16] <Tom_itx> no
[10:41:32] <Vikingsraven> anyone actually got i working first time?
[10:41:32] <Tom_itx> some of those wiki articles are rather dates though
[10:41:44] <Tom_itx> dated*
[10:41:53] <Vikingsraven> it
[10:42:53] <Vikingsraven> tried the hal setup for a joypad as well not had much luck with that either
[10:45:28] <zeeshan|2> damn you pressure transducer
[10:45:33] <zeeshan|2> why do you tell me -0.37V!!
[10:45:44] <ssi> is it back:P
[10:45:46] <ssi> backwards
[10:45:51] <Tom_itx> negative pressure
[10:45:52] <ssi> why are half my words getting dropped? D:
[10:45:57] <zeeshan|2> youre supposed to go from 0.5 to 4.5V!
[10:45:59] <Tom_itx> it's like negative resistance :D
[10:46:23] * Tom_itx switches ssi to full duplex
[10:46:27] <zeeshan|2> lol
[10:47:35] <malcom2073_> ssi: Alcohol..... is a hell of a drug
[10:47:44] <zeeshan|2> has anyone used visual studio or visual studio express?
[10:47:57] <ssi> :D
[10:48:22] <norias> malcolm2073_: https://www.youtube.com/watch?v=u0UfKQYGPFI
[10:49:50] <malcom2073_> Meh I don't have good enough internet here to watch youtube heh
[10:50:23] <norias> amazing
[10:51:05] <malcom2073_> Hotel internet ftl
[10:51:40] <norias> hahahahaha
[10:52:02] <norias> "Teenage angst has paid off well, now I'm bored and old."
[10:52:11] <norias> Listening to that line again, 20 some years later
[10:52:16] <norias> gives me a chuckle
[10:52:32] <malcom2073_> I was *quite* the angsty teenager. I'm glad I turned out so happy
[10:52:38] <malcom2073_> could've been way worse
[10:52:56] <furrywolf> argh. who wants to change a tire on my car for me? I'll give you $5.
[10:53:12] <malcom2073_> furrywolf: $5 + travel expenses and you're there
[10:53:36] <malcom2073_> I'd totally change a tire for the opportunity to travel
[10:54:07] <furrywolf> I need to put on a matching set of tires before trying to get it aligned, and I can't even lift a tire.
[10:54:56] <furrywolf> unfortunately, I can't afford to travel myself, much less pay for someone else to do so...
[10:55:00] <MrSunshine> heh, a friend of mines 3 jaw chuck is kinda worn . .work moves around in it so we tore it apart ... the scroll can move over 1mm in side play inside the thing ...
[11:23:37] <CaptHindsight> http://www.itworld.com/article/2941134/business/foxconns-ceo-backpedals-on-robot-takeover-at-factories.html see robots can't replace skilled manufacturing workers , just bankers, CEO's and politicians :)
[11:24:23] <shaun413> learning meshcam
[11:24:26] <shaun413> should be interesting
[11:42:34] <ssi> that's what I need to do
[11:42:39] <ssi> I need to get into the robot banker industry
[11:51:16] <Jymmm> This needs to go on "I fixed it" https://www.youtube.com/watch?v=hmAAT_o6W8U
[11:52:29] <ssi> wow I don't feel so bad about my roof now
[11:53:04] <Jymmm> Easiest demo job ever!
[11:53:55] <Jymmm> I really hate tar shingles
[11:54:08] <Jymmm> ancient technology
[11:54:53] <ssi> you more of a tin roof kinda guy? :P
[11:56:04] <Jymmm> That, or we hve shitloads of materials these days... silicone, even rhino truck bed spray on liners
[11:56:28] <malcom2073_> Hah, "“Our workers very much love to work at this company,” Gou said. “If I put out a recruitment poster, crowds of people will come. We’re not afraid that we can’t hire workers.”" I'm pretty sure he entirely missed the point of the criticism
[11:57:10] <malcom2073_> If walmart puts out a help wanted poster they get innundated with applications, doesn't mean it's a good place to work
[11:58:07] <Rab> Jymmm, rhinocoating your roof is an interesting idea, but I suspect there are many ways it could get damaged...and I don't know if the solution for sealing cured rhinocoat is more rhinocoat.
[11:58:20] <Jymmm> malcom2073_: Hey now, walmart puts a life insurance policy for every one of their employees! It's how they pay therir executives bonuses.
[11:58:31] <malcom2073_> Jymmm: Hehe
[11:58:38] <Jymmm> malcom2073_: I'm not kidding.
[11:58:47] <malcom2073_> Jymmm: I know, that's why I'm laughing
[11:59:30] <Jymmm> Rab: https://www.youtube.com/watch?v=FwnhFxkiXxg
[12:02:03] <Rab> Hmm...I think the same criticism applies. If a tree branch goes through the layer, I don't know how you would easily repair it.
[12:03:01] <Jymmm> Rab: True, but I would think there might be a repair can of stuff? maybe, would make sense instead of hauling up a whole spray setup. Maybe brush on
[12:03:36] <Jymmm> renesis: Just SOEMTHING, anything better than tar shingles
[12:04:12] <Jymmm> silicone stick to pretty much everything; would seem easy to patch/repair
[12:04:37] <Rab> Jymmm, I'm concerned that the new stuff might not adhere to the old stuff. And it doesn't seem stable under UV light, there's a protective coating. So you have to somehow remove the goop to repair the decking, reapply new goop and hope it adheres watertight to the old goop, apply new protective coating and hope it's contiguous with the old coating...seems messy.
[12:05:28] <Rab> Someone in here was describing german-style tile roofs, good for 100+ years...that sounds good to me. Probably more expensive than rhino.
[12:05:29] <Jymmm> Rab: That video shows over an existing roof, but I'm talking new roof on substrate directly (plywood)
[12:05:57] <Jymmm> Rab: Maybe nail/screw down strips for mechincal grip
[12:06:09] <Jymmm> Rab: very much like DIN rail
[12:09:32] <Jymmm> Rab: Heh, carbon fiber fabric impregnated with some silicone / epoxy-like stuff =)
[12:10:40] <Rab> Jymmm, you don't even need a structure! Just make a big bubble and maintain positive interior pressure.
[12:10:50] <CaptHindsight> FEVE fluorinated vinyl esters are the only liquid coatings that last for 50+ years
[12:10:56] <Jymmm> Rab: there we go =)
[12:11:15] <Rab> The university here has an all-weather practice field that works like that.
[12:11:19] <Rab> (football)
[12:11:52] <Jymmm> Rab: Maybe even instead of plywood, premade roof sheets that just snap-n-seal together
[12:12:27] <Rab> http://grfx.cstv.com/schools/tex/graphics/indoor_facility_530.jpg
[12:12:57] <Jymmm> I'm just saying that we have this wonderful technology and materials today, why are we using ancient on our roofs that we KNOW are going to fail
[12:13:05] <Jymmm>
[12:13:07] <Rab> Jymmm, that's basically how model metal roofing works.
[12:13:12] <shaun413> yeas it works
[12:13:14] <Rab> s/model/modern
[12:13:16] <shaun413> i cut a perfect circle :P
[12:13:19] <furrywolf> if I had to build a new house with a new roof, I'd use metal roofing. seems to last roughly forever.
[12:13:23] <Rab> shaun413, excellent!
[12:13:41] <furrywolf> Jymmm: because the roofing industry needs to stay in business.
[12:13:47] <shaun413> thanks
[12:13:57] <shaun413> now to try something more interesting?
[12:13:59] <furrywolf> if they sell you a roof that lasts forever, you won't keep buying more roofs. cars are similar.
[12:14:00] <CaptHindsight> aluminum panels with FEVE will last 100+ years
[12:14:31] <Rab> furrywolf, I like metal roofing a lot. I think it's totally worth the cost. Unfortunately I've done a poor job trimming the trees back from my metal roof in years past, and the galvanization has gotten abraded. Something to keep in mind.
[12:14:46] <CaptHindsight> I think that Rhino coatings are just ceramic with urethane
[12:15:10] <furrywolf> why don't we have corrosion-resistant aluminum cars with high-tech coatings? they're lighter, stronger, faster, and last longer. they cost more to build, but would last longer to make up for it. but car manufacturers like selling you new cars repeatedly.
[12:15:53] <CaptHindsight> furrywolf: we can have those, they just don't make them
[12:16:07] <furrywolf> if you try making a rust-proof car, you get framed for trafficing cocaine. :)
[12:17:01] <CaptHindsight> I'm actually working on a radcure FEVE coating that last 50+ years, and by last it just loses gloss vs needs recoat
[12:18:45] <CaptHindsight> from what I can see in the Rhono MSDS they are just urethanes with particles
[12:18:50] <CaptHindsight> ceramics
[12:19:09] <CaptHindsight> urethanes are good for 10-20 years
[12:20:47] <CaptHindsight> FEVE's were developed in the 80's, there is proof of it's durability for 30+ years in the field
[12:21:06] * furrywolf checks the news, and sees that the supreme court has decided that *gasp* it's perfectly OK to marry whomever you love.
[12:21:10] <CaptHindsight> 60+ in the lab using accelerated tests, UV, salt spray etc
[12:22:06] <CaptHindsight> FEVE with ceramic for roofing might last a lifetime
[12:22:46] <Rab> A lot of car mfgs are moving to aluminum body panels, actually, in an effort to keep weight down.
[12:23:19] <Rab> Anodized aluminum would be wicked, but also impossible to repair.
[12:23:29] * furrywolf checks the channel for mature, intelligent, sane, practical, women who are good with a strapon, and concludes the recent surpreme court decision won't help any here.
[12:23:29] <CaptHindsight> Land Rovers from the 50's still have bodies in great shape
[12:23:48] <furrywolf> CaptHindsight: that's because they're birmaloy or whatever made-up name for aluminum they used.
[12:24:14] <CaptHindsight> anodize also deosn't hold up well to alkalines
[12:24:31] <CaptHindsight> furrywolf: yes, they last too long :)
[12:25:07] <CaptHindsight> aluminum with a FEVE coating is easy to repair
[12:25:37] <CaptHindsight> aluminum + primer + color coat + clear
[12:25:58] <CaptHindsight> now the color might fade but it won't lose gloss
[12:26:12] <CaptHindsight> lead color last ages
[12:26:25] <CaptHindsight> but then there's the environmental concerns
[12:26:56] <furrywolf> car makers probably think we all use the paint chrysler used in the '90s. you know, the stuff that fell off by the '00s. :P
[12:27:10] <CaptHindsight> ford in the 80's
[12:27:33] <CaptHindsight> anything metallic was the color of the primer in a few years
[12:27:44] <CaptHindsight> didn't they use enamels?
[12:28:00] <Rab> furrywolf, the strapon-using women I've know don't like complainers.
[12:28:11] <_methods> buwhahahhahahah
[12:28:25] <alex4nder> wut
[12:28:38] <furrywolf> that's not very nice.
[12:28:39] <alex4nder> oh
[12:29:12] <Rab> furrywolf, I can't help their preferences!
[12:29:27] <furrywolf> good thing I'm not a complainer. :P
[12:33:24] * furrywolf bets a lot of people are getting married today
[12:35:57] <ssi> it's about time that non-hetero couples can experience the misery that is modern marriage
[12:36:13] <furrywolf> lol
[12:37:17] <_methods> +1
[12:37:18] <alex4nder> now I can complain, because my 1/3rd gender isn't recognized, and allowing my poly marriage to happen
[12:37:31] <alex4nder> time to go back to the drawing board
[12:37:36] <ssi> what in the world is a 1/3rd gender
[12:37:43] <_methods> pagina
[12:37:49] <_methods> penigina
[12:37:49] <alex4nder> ssi: listen and believe. don't question me.
[12:37:51] <ssi> micropenis?
[12:37:56] <_methods> shrinkage
[12:38:00] <PetefromTn_> the american freak show continues...
[12:38:15] <_methods> transgender homo
[12:38:28] <Rab> It's about time that two hetero Libertarians can sanctify their tax-avoidance union!
[12:38:40] <ssi> Rab: yeah that's what's been on my mind :D
[12:38:49] <ssi> I've been talkin about getting gaymarried for tax purposes for YEARS
[12:38:53] <alex4nder> yah, this is an MRA victory.
[12:38:56] <Rab> ahaha
[12:39:09] <furrywolf> MRA?
[12:39:20] <alex4nder> men's rights activists
[12:39:26] <_methods> yeah this is pretty spiffy for dudes that want to stay single and rep tax bene's of marriage
[12:39:35] <_methods> s/rep/reap
[12:39:56] <_methods> everyone in the military will be gay in no time
[12:39:57] <Rab> Not that I consider that an argument against gay marriage.
[12:40:01] <furrywolf> ... you do know it applies equally to women, right?
[12:40:03] <ssi> yeah man I need to find a single dude who likes airplanes and cnc machines, makes significantly less money than me, needs health insurance, and is an excellent wingman
[12:40:07] <ssi> literally and figuratively :D
[12:40:26] <_methods> new meaning to bro
[12:40:32] <Rab> ssi, it's not gay if you're married.
[12:40:36] <_methods> hahahha
[12:40:39] <alex4nder> furrywolf: you're missing the point. this is a perfect opportunity for guys to not have to give in to the matriarchy.
[12:40:39] <ssi> ...and high five afterward
[12:40:52] <alex4nder> a get out of jail free card, for straight men
[12:40:57] <_methods> amen women will totally be nothing but sex slaves now
[12:41:10] <alex4nder> _methods: have you been on tinder?
[12:41:14] <furrywolf> ... wtf?
[12:41:15] <_methods> hahah no
[12:41:23] <alex4nder> ;)
[12:41:54] <_methods> pretty sure you're not allowed to say .......wtf?
[12:42:09] <ssi> women have priced themselves out of the marriage market
[12:42:42] <alex4nder> that's the big joke.
[12:42:48] <furrywolf> good thing women can now marry each other, then?
[12:42:55] <alex4nder> we have marriage equality, right at the time people are starting to realize getting married is dumb.
[12:42:55] <PetefromTn_> CaptHindsight Hey man was wondering if I could get your opinion on a power supply for anodizing..
[12:43:08] <ssi> if they marry each other, which one gets all the shit in the divorce?
[12:43:23] <Rab> ssi, the one with the kids.
[12:43:59] <ssi> naturally
[12:44:39] <ssi> PetefromTn_: anodizing is nasty
[12:44:42] <ssi> I'd just send that shit out
[12:44:47] <alex4nder> yah
[12:44:49] <alex4nder> anodizing sucks
[12:44:56] <alex4nder> unless you want to get into the business of anodizing things
[12:44:57] <furrywolf> I've been thinking of trying annodizing, but haven't yet.
[12:45:08] <furrywolf> sending it out is very expensive
[12:45:09] <ssi> the fumes will eat your machines
[12:45:10] <PetefromTn_> Too late
[12:45:14] <furrywolf> so is powder coating, another thing I want to try.
[12:45:15] <PetefromTn_> already started buying the stuff
[12:45:20] <ssi> powder coating is easier
[12:45:26] <PetefromTn_> I make a bunch of aluminum parts
[12:45:36] <PetefromTn_> and want/need to be able to offer anodizing
[12:45:55] <PetefromTn_> plus I want to experiment with splash anodizing and cool color schemes
[12:46:03] <_methods> be careful what you wish for lol
[12:46:04] <alex4nder> you making paintball gear?
[12:46:15] <ssi> lol
[12:46:18] <PetefromTn_> no wishing involved
[12:46:27] <PetefromTn_> just gotta start doing it here
[12:46:29] <Rab> PetefromTn_, didn't you have a major job screwed up by the outside anodizing shop? Or was that someone else?
[12:46:37] <_methods> i hate all forms of finishing i just send all that stuff out
[12:46:42] <PetefromTn_> no not me
[12:47:09] <PetefromTn_> the local anodizer people only want to cater to large quantities of parts
[12:47:16] <PetefromTn_> makes me a nobody in most respects
[12:47:23] <PetefromTn_> so fuck em'
[12:47:30] <PetefromTn_> I'll do it myself
[12:47:35] <ssi> I know dem feels bruh
[12:47:42] <ssi> I went down that road too
[12:47:43] <ssi> and it sucks
[12:47:48] <ssi> had holes in all my clothes
[12:47:53] <ssi> everything steel in the vicinity rusted
[12:48:04] <ssi> had a hard time getting good deep colors
[12:48:08] <PetefromTn_> gonna do it outside
[12:48:44] <Rab> ssi, any issues with fading or dye coming off?
[12:48:49] <_methods> yeah looks like CaptHindsight's colors fix all that
[12:48:56] <ssi> no, the pieces I did that came out well have lasted
[12:49:10] <_methods> don't even need to heat the dye
[12:49:14] <PetefromTn_> I am anxious to try Capt's stuff here
[12:49:24] <ssi> I was just using walmart Rit dye junk
[12:49:32] <_methods> yeah good luck with that
[12:49:34] <ssi> heheh
[12:50:11] <PetefromTn_> Working on a design for a kart that will hold the coolers and electronics I can roll out of the shop on nice days and do it outside
[12:50:21] <_methods> oh jesus obama is here
[12:50:26] <ssi> onoes
[12:50:28] <_methods> glad i don't have to drive anywhere
[12:50:38] <PetefromTn_> what a joke
[12:50:42] <ssi> http://tfr.faa.gov/save_pages/detail_5_6660.html
[12:50:44] <ssi> shonuff
[12:51:00] <ssi> oh wait that's 6/29
[12:51:08] <_methods> asshole should have done it in columbia
[12:51:16] <_methods> come to our town and stir this shit up......thx
[12:51:28] <ssi> http://tfr.faa.gov/save_pages/detail_5_4342.html
[12:51:30] <ssi> that one's worse
[12:51:37] <alex4nder> _methods: he recently shut down my town as well
[12:51:45] <alex4nder> _methods: in order to do a TPP gladhand with Nike
[12:51:49] <_methods> ugh
[12:51:55] <_methods> yeah i hope they canc that shit
[12:51:59] <PetefromTn_> anytime the president comes to any town it basically closes down everything...
[12:52:01] <alex4nder> and tell our governor how happy he was about her latest gun ban BS
[12:52:02] <ssi> this tpp nonsense is a big problem
[12:52:26] <PetefromTn_> trajectory planner? LOL
[12:52:30] <_methods> the only towns i know that prez showing up has virtually no effect are fayetteville and columbus
[12:52:43] <PetefromTn_> no such animal
[12:52:49] <_methods> they come by so often its no big deal usually
[12:53:09] <_methods> they land right on base and stay on the reservation
[12:53:31] <_methods> not like there is anything to see off the post in fayetteville or columbus lol
[12:55:24] <MrHindsight> our dyes are solvent dye not water based, so no heating, no bath, no ph matching, etc etc
[12:55:42] <PetefromTn_> that is so kickass...
[12:55:53] <PetefromTn_> Can't wait to try it out..
[12:56:07] <furrywolf> I'm enough in the middle of nowhere that no one ever visits here, ever.
[12:56:10] <MrHindsight> Rit works but you have to have the dye bath dialed in
[12:57:12] <PetefromTn_> MrHindsight Hey man I started picking up anodizing stuff yesterday. Got a bunch of large coolers and was looking at some of those powders you linked me to.
[12:57:34] <MrHindsight> http://imagebin.ca/v/263WRWAvglKW 6 years unsealed and not even in a sealed bag
[12:57:53] <MrHindsight> our dye on the left, markers on the right
[12:58:09] <Rab> MrHindsight, do y'all have a web presence?
[12:58:09] <MrHindsight> Sharpie, marks-a-lot
[12:58:17] <PetefromTn_> http://www.ebay.com/itm/30V-10A-110V-Precision-Variable-DC-Power-Supply-Digital-Adjustable-w-Clip-Cable-/271608504736?pt=LH_DefaultDomain_0&hash=item3f3d20e1a0 Does this power supply look like it would work okay?
[12:58:44] <PetefromTn_> it does not actually say constant current..
[12:58:57] <furrywolf> it doesn't say it, but it is.
[12:59:17] <MrHindsight> Rab: you can order the dyes from the dyes from http://www.bucktownpolymers.com/anodize00.html
[12:59:19] <Rab> PetefromTn_, sometimes those no-name bench PSUs need a lot of rework to be safe and reliable.
[12:59:26] <Rab> MrHindsight, thx!
[12:59:56] <furrywolf> and it does say it! current regulation is +/- 0.2% +/- 3ma line or load.
[12:59:59] <Rab> "WUXIQIAOWEI ELECTRONICS CO., LTD" uh huh
[13:00:04] <PetefromTn_> I have a friend I speak to a lot that has that one and he seems to like it..
[13:00:53] <PetefromTn_> was hoping to get our resident anodize master's opinion on the unit....
[13:02:10] <furrywolf> I don't know more than the basics of annodizing, but I can tell you that power supply is constant current. :)
[13:02:26] <PetefromTn_> yeah thanks I got that ;)
[13:02:35] <MrHindsight> 50/50 chance of getting a good one, the nice thing about Automation Technologies is that they are local
[13:02:40] <MrHindsight> for me :)
[13:03:49] <furrywolf> what maximum voltage do you need for your annodizing?
[13:03:55] <PetefromTn_> I would like to get one from them and the one you recommended it really nice but I saw on this website they use something similar to the cheaper one... http://www.anodizeworld.com/power-supply.html
[13:05:07] <PetefromTn_> I was also gonna order the nickel acetate, the cleaner and desmut/etch stuff from them last night but they are apparently in Canada and some of the items say shipping is expensive or not available to US.
[13:07:15] <MrHindsight> heh Casewell sells anodize masks for $20/pint
[13:07:24] <MrHindsight> I should sells kits
[13:07:49] <MrHindsight> casewell materials are pricey
[13:07:55] <PetefromTn_> indeed
[13:08:12] <MrHindsight> http://www.caswellplating.com/aluminum-de-oxidizer-de-smut-5-gal-makes-40-gals.html
[13:09:00] <PetefromTn_> have you bought anything from that anodizeworld?
[13:09:06] <MrHindsight> http://www.caswellplating.com/anodizing-dye-sample-kit.html wtf $80 for a few sample dyes?
[13:09:36] <furrywolf> I'd love to do my own chrome, but everything that's bad about annodizing, is much worse with chrome.
[13:09:40] <ssi> yeah
[13:09:45] <ssi> my grandfather used to do chrome
[13:09:52] <PetefromTn_> chrome is NASTY process
[13:10:10] <MrHindsight> yeah stay away from Chrome
[13:10:22] <MrHindsight> polish and brite-coat/dip
[13:10:24] <PetefromTn_> lots of people do nickel plating tho apparently
[13:10:46] <furrywolf> I don't know if people with vehicles with bright nickel bumpers...
[13:10:52] <furrywolf> s/with/want
[13:10:58] <PetefromTn_> MrHindsight Have you bought anything from that Anodizeworld?
[13:11:17] <MrHindsight> PetefromTn_: no we just buy raw material
[13:11:26] <MrHindsight> mix our own stuff
[13:12:07] <PetefromTn_> I need to get some nickel acetate, some degreaser/cleaner, and some etch solution going here so I can try this.
[13:12:50] <PetefromTn_> would rather not get screwed by caswell for the stuff..
[13:13:35] <MrHindsight> have to go, but i can look for lower cost sources later
[13:14:53] <MrHindsight> PetefromTn_: try http://www.usspecialty.com/product_chemicals.php
[13:15:26] <MrHindsight> http://www.usspecialty.com/tds.php htye take credit cards and Paypal
[13:15:44] <PetefromTn_> is this the stuff you use?
[13:16:03] <MrHindsight> we make our own, but it's all similar
[13:16:45] <ssi> http://threepanelsoul.com/comics/2014-08-19-336.png
[13:16:50] <furrywolf> bbl
[13:16:53] <PetefromTn_> I mean is it the same sponge on/airbrush on stuff or is that the water based bath stuff
[13:17:13] <MrHindsight> PetefromTn_: at casewell?
[13:17:23] <PetefromTn_> no at USspecialty
[13:17:32] <MrHindsight> looks like all water based
[13:18:57] <MrHindsight> the only solvent dyes I have seen are by Clariant in a thick solvent for screen print
[13:19:09] <MrHindsight> alumaprint
[13:19:16] <MrHindsight> or similar
[13:22:12] <PetefromTn_> OK
[13:24:09] <DaPeace> anybody here that could help me scaling an encoder-input in linuxcnc?
[13:24:27] <DaPeace> dont really understand how that works
[13:29:02] <zeeshan-laptop> i must be going crazy
[13:29:13] <ssi> "going"?
[13:29:16] <zeeshan-laptop> i hook up the pressure transducer signal in single ended mode and it reads sane values
[13:29:21] <zeeshan-laptop> but if i hook it up in differential mode
[13:29:28] <zeeshan-laptop> it gives me the dreaded -.3v
[13:29:35] <zeeshan-laptop> Die ssi!
[13:29:39] * zeeshan-laptop goes insane on yu
[13:38:29] <CaptHindsight> whatever happened to to all the composite car bodies from the 90's?
[13:38:46] <CaptHindsight> lasted too long?
[13:38:52] <zeeshan-laptop> lol
[13:38:56] <zeeshan-laptop> people died too much in em
[13:39:05] <zeeshan-laptop> the vette is probably the unsafest car
[13:39:11] <CaptHindsight> or were they so cheaply made the bodies broke down
[13:39:23] <zeeshan-laptop> nope, defnitely not that
[13:39:24] <CaptHindsight> was it all blamed on safety?
[13:39:29] <Jymmm> anyone worked on retrofitting a shipping container?
[13:39:37] <zeeshan-laptop> Jymmm: as a workship
[13:39:40] <zeeshan-laptop> or living space?
[13:39:46] <Jymmm> zeeshan-laptop: workshop
[13:39:53] <CaptHindsight> Jymmm: much too heavy as a Halloween costume
[13:39:55] <zeeshan-laptop> ive been planning to
[13:39:59] <zeeshan-laptop> i have a 40 and 20 foot container
[13:40:12] <Jymmm> zeeshan-laptop: windows? air? heat?
[13:40:16] <zeeshan-laptop> it'd be quite tight
[13:40:19] <zeeshan-laptop> no, bunker style
[13:40:23] <Jymmm> ?
[13:40:29] <zeeshan-laptop> you'd install a vent fan
[13:40:32] <zeeshan-laptop> relatively easily
[13:40:38] <zeeshan-laptop> no need for windows
[13:40:41] <zeeshan-laptop> you can hang lights
[13:41:03] <CaptHindsight> http://www.architecturendesign.net/22-most-beautiful-houses-made-from-shipping-containers/ some of these are great Jymmm
[13:41:04] <Jymmm> zeeshan-laptop: I'm thinking AC
[13:41:23] <Jymmm> zeeshan-laptop: Window AC
[13:41:27] <zeeshan-laptop> ah
[13:42:04] <CaptHindsight> I bet zoning and codes are an issue
[13:42:18] <Jymmm> No, they are permitted
[13:42:35] <CaptHindsight> in rural parts of CA?
[13:42:35] <zeeshan-laptop> so is this a good sign that my flyback diode is working
[13:42:46] <Jymmm> just the setbacks per parcel
[13:42:50] <zeeshan-laptop> when i manually touch a wire to ground from the other end of the solenoid which has a diode in parallel
[13:42:54] <zeeshan-laptop> there no longer is a massive spark
[13:42:58] <zeeshan-laptop> :)
[13:43:02] <Rab> CaptHindsight, composite car bodies like the plastic Saturn roofs that melted in the sun?
[13:43:22] <CaptHindsight> Rab: sounds like poor material choice
[13:44:25] <Jymmm> zeeshan-laptop: So, other than paint, is there any maintance?
[13:44:35] <zeeshan-laptop> the ground you put it on
[13:44:39] <zeeshan-laptop> itll sink over time
[13:44:43] <zeeshan-laptop> if its just soil
[13:44:49] <zeeshan-laptop> ours have sank a good 1 foot
[13:44:50] <Jymmm> zeeshan-laptop: concrete slab?
[13:44:57] <zeeshan-laptop> i think you'd be okay with gravel
[13:45:02] <zeeshan-laptop> 4" deep
[13:45:07] <Jymmm> ok
[13:45:24] <Jymmm> zeeshan-laptop: did you change anything in it? doors?
[13:45:30] <CaptHindsight> zeeshan-laptop: so a laser or similar that vaporizes a car on impact (the other guys car) would solve the problem
[13:45:40] <zeeshan-laptop> rofl CaptHindsight
[13:45:57] <zeeshan-laptop> Jymmm: no
[13:46:03] <zeeshan-laptop> we just have lights in there
[13:46:19] <Jymmm> CaptHindsight: Vehicle roof top version of this... https://en.wikipedia.org/wiki/Phalanx_CIWS
[13:46:38] <Jymmm> CaptHindsight: That being an anti-traffic device =)
[13:47:13] <Jymmm> zeeshan-laptop: Anything I should be aware about shipping containers in general?
[13:47:21] <Jymmm> zeeshan-laptop: I have NFC
[13:47:50] <CaptHindsight> Jymmm: if you knew that was the possible consequence for being careless wouldn't that motivate drivers to change their habits?
[13:48:07] <CaptHindsight> furrywolf would not be in his current situation
[13:48:10] <Jymmm> CaptHindsight: Fuck no =)
[13:48:33] <CaptHindsight> Jymmm: well it would quickly reduce the number of them on the road
[13:50:11] <Rab> Jymmm, there's a "foot" at each corner. I'd cast or put down a concrete block under each foot, then you can easily jack up and shim to level the container.
[13:51:20] <zeeshan-laptop> fuck yes!
[13:51:21] <Rab> The people I know with containers usually put them on railroad ties. You also get some ground clearance under the container for tires and other snake habitat.
[13:51:25] <zeeshan-laptop> all my DIO is working!!!!!!
[13:51:26] <zeeshan-laptop> !!!!!!!!!11
[13:51:33] <Rab> zeeshan-laptop, congrats!
[13:52:19] <CaptHindsight> the snakes keep the rats away
[13:52:57] <Rab> Jymmm, also, see if you can get a reefer: refrigerated container. They're somewhat more expensive but well-insulated and finished out with stainless steel and slot flooring for easy hosing down.
[13:54:09] <Rab> I theorize that the ss slot flooring would be a good way to anchor machine tools (but maybe also lose your tooling).
[13:54:48] <zeeshan-laptop> ps mccdaq is a great company
[13:54:58] <zeeshan-laptop> really helpful people. you get directly to their engineers
[13:55:04] <zeeshan-laptop> not some noob
[13:55:44] <Jymmm> Rab: ah, nice idea
[13:55:51] <CaptHindsight> Rab: stuff the slots with something when not used
[13:58:08] <Rab> Garden hose would probably work: http://portablerefrigerationstorage.com/wp-content/gallery/40-refrigerated-containers/40-Refrigerated-Container-Floor-Close-Up.jpg
[13:58:27] <Rab> Use the bed as the floor of a gigantic, container-sized router.
[13:58:27] <CaptHindsight> how many traffic accidents are you allowed to cause in country's like Germany before you lose your license?
[13:59:48] <CaptHindsight> weld 2 containers together at the floor and flip it, shop by day and home by night
[14:05:05] <Jymmm> $1300 for the permit?! WTF
[14:06:04] <Jymmm> Fuck it, I'll install four $3 harborfreight wheels on the cargo container, then it's a trailer no subject to permit
[14:06:12] <Jymmm> not*
[14:42:31] <malcom2073_> Jymmm: If you have wasps, weld up the holes for locking it down and seal up the bottom. They are havens for wasps/bees
[14:43:29] <Jymmm> malcom2073_: what about how they do RR Ties? Tar/oil soaked or something?
[14:43:48] <malcom2073_> Jymmm: You're talking about a metal shipping container?
[14:43:59] <Jymmm> malcom2073_: Yeah, but they have wooden floors
[14:44:12] <malcom2073_> It's the small holes that are the issue
[14:44:31] <Jymmm> malcom2073_: like rust holes, or ???
[14:44:58] <malcom2073_> No, shipping containers have a variety of holes and other latching points for picking them up, trying them down, locking the doors, etc
[14:45:06] <malcom2073_> In my area, you sit a shipping container outside in the summer, within a week you won't be able to approach it without getting stung
[14:45:45] <Jymmm> malcom2073_: Ah, plant sage?
[14:46:54] <malcom2073_> You could probably surround it with sage heh
[14:48:19] <Jymmm> malcom2073_: There are three things you can plant that cover most insects; lavender, sage, mint
[14:48:39] <Jymmm> I think there was one more
[14:50:54] <Jymmm> peppermint
[14:53:06] <Jymmm> malcom2073_: Curious, how much land are you on?
[14:53:24] <malcom2073_> Jymmm: Very little, 1.5 acres
[14:53:45] <Jymmm> malcom2073_: lol, well not "little" compared to 0.4 acre =)
[14:53:45] <malcom2073_> I don't have any shipping containers, I'm speaking from experience at work, where we've used them for storage, and office space
[14:53:55] <malcom2073_> Haha, little for where I am. My neighbor has over 100 :P
[14:54:19] <Jymmm> malcom2073_: True, and would like 2+ acres, but well, you know.
[14:54:29] <malcom2073_> Yeah, not always practical
[14:54:46] <Jymmm> how bulletproof are they?
[14:54:57] <malcom2073_> They're not.
[14:55:03] <Jymmm> 22lr?
[14:55:11] <Jymmm> 12ga birdshot?
[14:55:19] <malcom2073_> Unknown, but it's not *that* thick of metal
[14:55:30] <malcom2073_> Funny story, I was overseas and an ammunition storage container caught fire
[14:55:43] <malcom2073_> at the end, it was circular instead of rectangular, and if you went inside and looked up, it looked like a starry night, so many holes
[14:56:10] <Jymmm> malcom2073_: but it was stil a 6 sided continaer?
[14:56:26] <malcom2073_> More like a bulging cylinder :-P
[14:56:34] <Jymmm> or 6 sided strainer
[14:56:46] <malcom2073_> I'll have to find my pictures of it
[14:56:50] <Jymmm> Well, I guess it held the explotion
[14:57:00] <Jymmm> thats gotta say something
[14:57:13] <malcom2073_> No *really* big explosion, and it didn't hold the fire or other shrapnel
[14:57:24] <Jymmm> ah
[14:57:25] <malcom2073_> Nearby vehicles were toasted, and they were finding munitions spread about for weeks afterwards
[14:57:33] <Jymmm> ooooops
[14:57:38] <Jymmm> how did it start?
[14:59:29] <furrywolf> A friend tried moving a 40ft shipping container on a 20ft trailer. Only do that if you also want a color photo in your local paper.
[14:59:35] <malcom2073_> They have no idea. Best they can figure out, is something plastic got hot (it wasin the summer), allowed something else to fall off a shelf, and kick off a flare mortar which is what was the first boom and blew the doors open, after that the normal rounds started cooking off and made things worse
[15:00:25] <malcom2073_> I imagine someone got in trouble for it though regardless heh
[15:01:47] <Jymmm> Hmmm, theres a lot more to having a container than I ever considered; https://www.youtube.com/watch?v=4QsnpK_erfU
[15:02:10] <furrywolf> Everyone present was telling him it was a fucking stupid idea. "It'll be fine!". got about 500ft to the first corner, lifted the back of the truck up...
[15:02:33] <furrywolf> there exists photos of it, because everyone was just waiting for this to happen to they could point and laugh...
[15:02:37] <Jymmm> furrywolf: 45ft up a mountain n a 20ft truck https://www.youtube.com/watch?v=OOjO-omkPAk
[15:03:12] <malcom2073_> Jymmm: The logistics aren't simple... but they're not terrible. Do a *LOT* of research haha
[15:03:33] <furrywolf> what is there to having a container? you buy it, and... you have a container.
[15:03:36] <Jymmm> malcom2073_: and $1300 permit PER structure - bastards
[15:03:46] <malcom2073_> Damn! Your area sucks
[15:03:52] <malcom2073_> I like your idea of sticking wheels under it
[15:03:53] <malcom2073_> :-D
[15:04:06] <malcom2073_> Don't even have to work
[15:04:09] <malcom2073_> just bolt wheels to it
[15:04:14] <Jymmm> malcom2073_: exactly
[15:04:17] <furrywolf> unlike that video (which hasn't loaded yet - I just read the description), my friend had a 5000lb ford pickup, not a 17500lb freightliner. :P
[15:04:27] <malcom2073_> haha
[15:04:41] <Jymmm> furrywolf: oh, heh
[15:05:34] <Jymmm> I love how they get the container off the trailer.... just rip it off with a tractor =)
[15:05:43] <furrywolf> he loaded the 40ft container onto a 20ft trailer... this put around 10ft of container in front of the wheels, and 30ft of container behind the wheels. it was lifting his truck up in the air, so he tossed some crap in the bed until it tilted back down, and declared "it'll be fine!" even as every person around him was telling him it was stupid as fuck...
[15:06:29] <Jymmm> furrywolf: sounds reasonable to me. but then again not my truck =)
[15:06:29] <furrywolf> got to the first turn, trailer and back of truck just kept going straight, which everyone but him predicted...
[15:06:52] <furrywolf> then everything went sideways.
[15:06:56] <Jymmm> lmao
[15:07:01] <furrywolf> across both lanes of the freeway.
[15:07:08] <Jymmm> Nice
[15:07:24] <furrywolf> took them several tow trucks to get it back rightside up, freeway blocked for like an hour...
[15:07:46] <Jymmm> malcom2073_: Hey now, this is a n idea.... https://www.youtube.com/watch?v=dIEEd10apF0
[15:08:06] <Jymmm> malcom2073_: 5th wheel puling a container
[15:08:23] <furrywolf> I don't know about where you are, but I've yet to ever hear of a permit being needed for a container here.
[15:08:25] <furrywolf> they're not considered a structure
[15:08:35] <Jymmm> furrywolf: county?
[15:08:52] <furrywolf> unless you did something to permanently anchor it, like pour a concrete foundation or plumb septic to it, it's movable property, like a vehicle.
[15:08:56] <Jymmm> furrywolf: which county are you in?
[15:08:58] <furrywolf> humboldt, california
[15:09:23] <Jymmm> furrywolf: Hmmm, no idea
[15:10:48] <furrywolf> where the heck are you that requires a permit for movable property?
[15:10:55] <Jymmm> furrywolf: 14KB permit required http://www.hcnv.us/bldg_dpt/documents/Storagecontainer12-13_000.pdf
[15:11:01] <furrywolf> there's proper legal terms for fixed/movable that I can't remember right now.
[15:11:28] <Jymmm> furrywolf: if you find them please let me know.
[15:11:44] <Jymmm> furrywolf: $1300 for a permit is excessive
[15:11:57] <furrywolf> lol, you're in humboldt, nv, while I'm in humboldt, ca?
[15:11:59] <Jymmm> furrywolf: no rush or anything
[15:12:14] <Jymmm> oh, did I get the wrong state?
[15:13:33] <furrywolf> yes :P
[15:14:20] <furrywolf> that seems like the type of dickhead ordinance that gets passed because someone thinks they're ugly, so invents an excuse (they're dangerous!) and abuses the permit process to try to ban them.
[15:15:02] <furrywolf> also, that sounds like it's aimed for permanently installed containers being used as buildings. you just need to claim it's movable.
[15:15:03] <Jymmm> furrywolf: Yep, PLUS re-engineering too... ventilation, man door (fire escape)
[15:15:29] <Jymmm> furrywolf: Yeah, thus the need for the legal definition
[15:16:07] <Jymmm> furrywolf: I still say head down to harborfreight and get four $3 tires and install them on the container
[15:16:07] * SpeedEvil wonders what the difference between a man-door and a woman-door would be.
[15:16:32] <furrywolf> still loading that video... heh, that container on his truck looks just like the 40ft container on the 20ft trailer did... most of it off the back. :P
[15:16:56] <Jymmm> SpeedEvil: purple?
[15:17:17] <Jymmm> SpeedEvil: sorry, I meant lavenender
[15:18:01] <furrywolf> I've been tempted to build a workshop on a trailer frame... so I can tow it with me when I move.
[15:18:12] <furrywolf> shipping containers are a bit small, and around here, EXPENSIVE.
[15:18:17] <furrywolf> a beat up 20ft is $2500.
[15:19:10] <furrywolf> you see gutted RVs pretty regularly... just build a 10ft wide shop on the frame from one.
[15:19:15] <furrywolf> s/RV/house trailer
[15:20:10] <furrywolf> I've seen people make shipping container dolleys that bolt to the ends... you could build one of those, and then they really couldn't claim it was a structure.
[15:20:14] <SpeedEvil> furrywolf: In general >8.5ft requires permits from damn near everywhere to tow
[15:20:56] <furrywolf> SpeedEvil: in general no one stops you until you get over 10ft... :P
[15:21:09] <furrywolf> I think around here 10ft needs a pilot car but not a permit, but I'm not sure.
[15:21:34] <furrywolf> I know you need a pilot car, but I'm not sure if you need a permit too.
[15:21:50] <furrywolf> you can do 12ft with a permit
[15:22:06] <furrywolf> (with a normal, easy to get permit... >12ft needs expensive engineering-reviewed permit)
[15:22:19] <XXCoder> furrywolf: too bad you cant come here theres $1000 containers here but dunno if 20 ft
[15:22:27] <XXCoder> stqacked, very tall piles of em
[15:22:34] <SpeedEvil> furrywolf: I'm going off stuff I recall from when I was googling RV widths in the USA
[15:22:34] <furrywolf> XXCoder: yes, I'm aware containers are cheaper elsewhere.
[15:22:36] <XXCoder> major shipping center here
[15:22:49] <furrywolf> it's cheaper to buy one down in san francisco and have it shipped up here than it is to buy from the local places.
[15:23:05] <SpeedEvil> Get one shipped from china, and pack it with stuff :)
[15:23:06] <XXCoder> funny, that
[15:23:37] <furrywolf> gah, I'm going to give up on that video. it's loaded barely a quarter of it so far.
[15:23:57] <XXCoder> wonder how many semis haling a cargo box and cargo box is actually the thing its hauling :P
[15:24:12] <XXCoder> SpeedEvil: would be funny yeah
[15:24:21] <XXCoder> sell stuff in it and it turns into profit
[15:25:02] <XXCoder> only one problem, high inital cost lol
[15:25:27] <furrywolf> I've seen log trucks driving on far narrower roads than that guy seems to be on.
[15:27:03] <zeeshan-laptop> wtf
[15:27:07] <zeeshan-laptop> am i doing this crap right
[15:27:13] <furrywolf> no
[15:27:22] <zeeshan-laptop> i got 2 pins coming out of a current source
[15:27:23] <zeeshan-laptop> 4-20mA
[15:27:28] <zeeshan-laptop> i got a resistor across the two pins
[15:27:36] <zeeshan-laptop> and and im measuring voltage across the resistor
[15:27:37] <archivist> in series
[15:27:40] <zeeshan-laptop> im getting nothing
[15:27:48] <furrywolf> is it a current source, or a current regulator?
[15:28:02] <archivist> a sink
[15:28:15] <zeeshan-laptop> pic comin
[15:28:27] <furrywolf> pic != datasheet with "hook stuff up like this" picture. :P
[15:28:31] <archivist> read the fm anyway
[15:32:52] <furrywolf> Jymmm: see if shipping containers count as chattel where you live, and what you have to do/not do to keep them that way.
[15:33:04] <Jymmm> chattle?
[15:33:26] <Jymmm> oh, hmmm
[15:33:35] <furrywolf> chattel. property that's not fixed to the real estate, like vehicles, things you can move around, etc.
[15:33:44] <Jymmm> right, got it
[15:33:49] <JT-Shop> zeeshan-laptop, what are you trying to measure?
[15:34:32] <furrywolf> of course, a local ordinance can override any generic legal definitions.
[15:35:22] <furrywolf> they could declare a shipping container to be a plains zebra and subject to a zookeeper's permit...
[15:35:41] <Jymmm> =)
[15:36:11] <Jymmm> furrywolf: But If I install lawnmower wheels on it, and get it defined as an off road trailer =)
[15:36:27] <Jymmm> furrywolf: then it's under chp/dmv =)
[15:36:54] <furrywolf> around here, mobile homes are like that... you have to keep the registration sticker current, however.
[15:37:15] <Jymmm> furrywolf: not for off road trailers as I understnd it
[15:37:37] <Jymmm> furrywolf: like a farmer pulls a trailer behinf a tractor
[15:37:54] <Jymmm> CHP is out to lunch so no answer
[15:37:58] <furrywolf> lol
[15:38:22] <furrywolf> what is the ordinance that requires you to have a permit?
[15:39:08] <Jymmm> nothing says the lawnmower wheels actually have to work =)
[15:39:27] <XXCoder> lol
[15:39:30] <Jymmm> "Sea/Land Cargo contianers used as storage buildings"
[15:39:41] <malcom2073_> Good thing it's not being used as a storage building :-D
[15:39:44] <XXCoder> it shouldnt be too hard to add wheels to cargo box
[15:39:52] <XXCoder> even legit working one
[15:40:18] <Jymmm> nope, just grab an axle from a junk or furrywolf's yard =)
[15:40:20] <zeeshan-laptop> fak sorry
[15:40:22] <zeeshan-laptop> had something blow up
[15:40:23] <zeeshan-laptop> lol
[15:40:29] <zeeshan-laptop> http://i.imgur.com/NrRkVkW.png
[15:40:31] <malcom2073_> kaboom?
[15:40:34] <zeeshan-laptop> yea
[15:40:40] <zeeshan-laptop> a hydraulic hose gave away at 5000psi
[15:40:53] <XXCoder> jy yeah some people got whecking yar er sorry I mean nice car collection
[15:41:01] <zeeshan-laptop> furrywolf: thats what im talking about
[15:41:04] <zeeshan-laptop> we talked about this yesterday
[15:41:05] <Jymmm> much much is it to have eaves repaird?
[15:41:06] <zeeshan-laptop> im physically doing it now
[15:41:09] <furrywolf> so don't say you're using it as a storage building.
[15:41:28] <furrywolf> you're using it for shipping, and lading cargo.
[15:41:37] <Jymmm> =)
[15:41:56] <XXCoder> yeah build a nice land drop so cargo sits level with ground even with wheels
[15:42:10] <XXCoder> yet styill can be towed out
[15:42:11] <furrywolf> ok, so it is a current source... does the manual mention anything you need to do to enable, configure, etc it?
[15:42:25] <furrywolf> url for this ordinance?
[15:42:39] <Jymmm> emailed to me
[15:42:49] <furrywolf> sonoma?
[15:44:45] <zeeshan-laptop> hmm
[15:44:55] <zeeshan-laptop> good q
[15:44:57] <zeeshan-laptop> will look
[15:45:04] <zeeshan-laptop> im hooking it up right yea?
[15:45:10] <zeeshan-laptop> its in series between the two terminals
[15:45:16] <zeeshan-laptop> and im measuring the voltage drop across the resistor
[15:45:31] <zeeshan-laptop> i got a 330 ohm resistor
[15:45:35] <zeeshan-laptop> well 3 1k ohms inparallel
[15:50:04] <zeeshan-laptop> looks like this controller doesnt have the module
[15:50:10] <zeeshan-laptop> ive triple verified it
[15:50:11] <zeeshan-laptop> garbage.
[15:50:26] <furrywolf> lol
[15:50:35] <furrywolf> what controller is this?
[15:51:37] * furrywolf has no clue what zee is working on
[15:52:05] <zeeshan-laptop> http://www.ebay.com/itm/OMRON-E53-AKF-BOARD-NEW-IN-BOX-/171778391935?pt=LH_DefaultDomain_0&hash=item27feca3f7f
[15:52:07] <zeeshan-laptop> this is what ineed
[15:52:09] <zeeshan-laptop> e5ek
[15:52:14] <zeeshan-laptop> omron
[15:53:33] <furrywolf> that still doesn't tell me what it is. ol
[15:53:37] <furrywolf> lol
[15:54:28] <zeeshan-laptop> pid controller
[15:54:30] <zeeshan-laptop> for heating and cooling
[15:54:37] <furrywolf> ah
[15:54:41] <furrywolf> so buy the board?
[15:54:53] <zeeshan-laptop> yea
[15:54:55] <zeeshan-laptop> i just placed an order
[15:55:03] <zeeshan-laptop> hopefully that is all it needs
[15:55:08] <furrywolf> not having the board might indeed result in no output. :)
[15:55:22] <zeeshan-laptop> wish it just output 0-5v
[15:55:23] <zeeshan-laptop> not 4-20
[15:55:32] <zeeshan-laptop> but iguess 4-20 mA lets you scale it to whatever
[15:55:44] <furrywolf> do they have a 0-5v board?
[15:55:48] <zeeshan-laptop> no
[15:55:51] <zeeshan-laptop> modbus
[15:55:53] <zeeshan-laptop> thats about it
[15:56:19] <zeeshan-laptop> http://media.digikey.com/pdf/Data%20Sheets/Omron%20PDFs/E5EK_2007.pdf
[15:56:28] <zeeshan-laptop> page 2
[15:56:32] <zeeshan-laptop> under options
[15:56:40] <Jymmm> Is it expensive to repair roof eaves?
[15:57:02] <furrywolf> so, 4-20ma to 0-5v is... 280 ohm resistor and a silicon diode?
[15:57:08] <furrywolf> Is it expensive to repair a car?
[15:57:16] <zeeshan-laptop> im just gonna resistor it up
[15:57:24] <Jymmm> or cheaper in the long run to replace the roof and have them replaced then?
[15:58:17] <furrywolf> ...
[15:58:37] <furrywolf> much like a car, roof eaves can have a wide variety of problems of varying severity.
[15:58:59] <XXCoder> eaves new word
[15:59:33] <XXCoder> interesting
[15:59:35] <furrywolf> is it expensive to repair where your neighbor shot it with a bb gun and left a little dent? no. is it expensive to repair where the redwood tree ripped it off the side of the house and then it rotted and then your neighbor's kids used it as a skateboard ramp? yes
[15:59:42] <zeeshan-laptop> fuck
[15:59:50] <zeeshan-laptop> i just realized the signal conditioning unit i got is the wrong one
[15:59:53] <XXCoder> it let out magic smoke?
[16:00:02] <zeeshan-laptop> it takes 0 to 5v input and outputs 0to 20mA
[16:00:07] <zeeshan-laptop> shoud be 4 to 20mA :(
[16:00:26] <zeeshan-laptop> losing resolution ;/
[16:00:29] <furrywolf> so get the right one. lol
[16:00:36] <zeeshan-laptop> dude this was 150$
[16:00:36] <zeeshan-laptop> lol
[16:00:40] <zeeshan-laptop> theyre gonna be pissed
[16:00:40] <furrywolf> losing resolution?
[16:01:02] <zeeshan-laptop> yes cause say i set 1V
[16:01:05] <zeeshan-laptop> and it outputs 2mA
[16:01:14] <zeeshan-laptop> the controller won't recognize the signal
[16:01:21] <furrywolf> ah.
[16:01:32] <zeeshan-laptop> maybe ill just make it work ;/
[16:01:38] <furrywolf> so your input device doesn't read below 4ma, and can't be configured to do so?
[16:01:48] <jdh> most have zero and span adjustments
[16:01:57] <furrywolf> bias the 0-5V.
[16:02:42] <furrywolf> use a voltage divider to scale the 0-5V to 0-4V, then an opamp to add 1V to it. :P
[16:03:33] <zeeshan-laptop> outside my comfort zone
[16:03:33] <zeeshan-laptop> :P
[16:03:53] <furrywolf> ok, then buy a fancy 0-20ma to 4-20ma converter. :P
[16:04:01] <furrywolf> there's plenty of loop isolators that can do things like that
[16:04:04] <zeeshan-laptop> ill just lose resolution
[16:04:31] <Deejay> gn8
[16:05:22] <furrywolf> you don't lose resolution... you lose the ability to read a portion of the values.
[16:05:32] <furrywolf> which will be recognized as a failure instead
[16:08:46] <zeeshan-laptop> ill just limit my voltage output
[16:08:50] <zeeshan-laptop> to go between a certain voltage..
[16:08:57] <zeeshan-laptop> so it correctly outputs 4-20mA
[16:09:23] <zeeshan-laptop> so ill always output for example 1-5V only
[16:09:33] <zeeshan-laptop> and 1V means 100 celsius
[16:09:41] <zeeshan-laptop> 5V means 500celsius
[16:10:26] <furrywolf> oh, so you're outputting the setpoint.
[16:10:37] <zeeshan-laptop> yes
[16:10:46] <furrywolf> wouldn't modbus/etc be better? :P
[16:11:10] <zeeshan-laptop> probably lol
[16:11:20] <zeeshan-laptop> https://www.dataforth.com/catalog/pdf/scm5b39.pdf
[16:11:31] <zeeshan-laptop> these guys dont show physical pin locations in this datasheet..
[16:11:32] <zeeshan-laptop> nice.
[16:11:33] <zeeshan-laptop> ..
[16:11:55] <zeeshan-laptop> this signal conditioning unit has 14 pins!
[16:11:59] <zeeshan-laptop> i thought it'd be 4. lol
[16:12:41] <furrywolf> probably labeled on the unit
[16:13:41] <zeeshan-laptop> nope
[16:13:53] <furrywolf> so you got one of the part numbers that does 0-20 instead of 4-20?
[16:13:58] <zeeshan-laptop> yes
[16:14:00] <zeeshan-laptop> -03
[16:14:18] <furrywolf> it might well be adjustable, or the manufacturer might tell you how to modify it.
[16:14:47] <furrywolf> does it have zero and span adjustments?
[16:15:04] <zeeshan-laptop> no
[16:15:25] <zeeshan-laptop> https://www.dataforth.com/family.view.aspx?familyid=57
[16:15:29] <zeeshan-laptop> thats the thing im looking at
[16:15:31] <zeeshan-laptop> its a dinky little box
[16:15:44] <furrywolf> so, you bought two modules that were the wrong ones... you need to read the datasheet BEFORE buying... :P
[16:15:53] <zeeshan-laptop> the one module i had from before
[16:15:54] <zeeshan-laptop> had no control
[16:17:08] <furrywolf> my back is starting to get too sore to sit up again... going back to lying down. bbl.
[16:18:11] <monttyle> Is this channel just about the software, or is it also about DIY?
[16:19:12] <XXCoder> diy too I guess
[16:19:22] <XXCoder> since #cnc channel died some time ago
[16:19:33] <XXCoder> and #diycnc sucks
[16:20:16] <XXCoder> op there warned me when I said something 4 times in a row but really it was just thought process
[16:20:20] <XXCoder> so yea
[16:20:39] <furrywolf> this channel is about all sorts of things, including linuxcnc, general cnc, cars, process control, and strapons. although I think I have more of the latter than everyone else here. The channel is NOT about mach3, or machines using it.
[16:21:26] <XXCoder> mach3 is pretty sucky from what I see anyway
[16:21:46] <monttyle> Thanks... I've been considering the merits of cartesian vs noncartesian CNC machines.
[16:23:39] <monttyle> delta 3d printers have demonstrated pretty well that you don't need X and Y to be fully mechanical to get decent results, and a triangular arrangement might be easier to scratch build.
[16:24:31] <kyle__> Is there any good starting reference for building a DIY lathe? I've been using 3d printers, but came across an old wood lathe at a garage sale....so I figured I'd CNC it up to learn.
[16:25:29] <monttyle> A wood lathe is not a CNC late. A wood lathe is just stand there and hold a chisel, a metal lathe at least holds the chisel for you
[16:26:02] <kyle__> monttyle: But the delta 3d printers can exactly map to carteasian printers. Polar printers can't exactly map.
[16:26:06] <kyle__> monttyle: From a math standpoint.
[16:26:31] <kyle__> So nobody does CNC conversions to wood lathes?
[16:26:46] <kyle__> They're really that different of a tool than metal ones?
[16:26:49] <monttyle> kyle__: There's not a whole lot there to convert.
[16:26:55] <monttyle> The tool holder is missing.
[16:27:37] <JT-Shop> kyle__, sure hundreds convert wood lathes to CNC but not anyone watching this second
[16:28:00] <kyle__> yeah... I did notice that. I ordered a threadded rod to build up some sort of carriage for a tool.
[16:29:08] <kyle__> I'm just assuming rod better than belt for this, for rigitidy, but I don't know lathes, so I was hoping there was some sort of good online reference to start from.
[16:29:54] <monttyle> kyle__: It's true its nonlinear, but 3d delta isn't perfectly linear either. Saw a plot of accuracy vs position and it gets hinky at the edges.
[16:31:38] <kyle__> monttyle: The tuning procedure to get the scaling right on them isn't confidence inspring, I'll admit that.
[16:31:43] <zeeshan-laptop> test
[16:32:45] <JT-Shop> failed
[16:33:00] <monttyle> Lots of 3d standard practices are less than confidence inspiring, like 'measure the bed and let the computer tilt the part to print it level'.
[16:34:20] <kyle__> That's __supposed__ to be to correct for minor flaws that crop up in levelling over time, and not to subtitute for poor configuration/tuning/build-quality.
[16:34:38] <kyle__> But yeah, lots of people are going the lazy route there.
[16:34:43] <monttyle> There's printers which can't be levelled any other way, and people who'll defend it to the death.
[16:35:35] <monttyle> There's a halfway compromise between pure X/Y and purely computed though, if my idea isn't completely insane: http://burningsmell.org/images/crazycnc3.gif There's two motors, one captive, one fixed. The left motor moves everything on the shaft. The right motor only moves itself.
[16:36:29] <XXCoder> monttyle: thats interesting setup
[16:37:11] <monttyle> Movement on X is done just by moving the left motor. Movement on Y is done by stepping one motor twice forwards, and the other 1 back. X would be purely linear, Y would not
[16:37:21] <XXCoder> monttyle: from what I see, it has a circle workspace. certainly odd
[16:37:25] <XXCoder> actually no
[16:37:39] <XXCoder> trangle
[16:37:45] <kyle__> XXCoder: trapazoidal I thought glancing at it.
[16:38:12] <XXCoder> nah trangle. at closest to rod it would be unable to move (assuming its fully extended and rod size is same)
[16:38:22] <XXCoder> trapazoidal more general word yeayh
[16:38:47] <monttyle> I drew triangles and square roots until my head hurt, but it's only supposed to be a short distance manipulator.
[16:39:01] <XXCoder> use?
[16:39:20] <monttyle> Milling very small parts. The end is a part holder. There'd be a miling head above
[16:39:29] <XXCoder> ahh cool
[16:39:42] <XXCoder> I guess it needs very high resolution
[16:41:30] <kyle__> I don't know if it would be an easier way of doing it, but it would look awesome and be ineteresting to see how it worked.
[16:44:17] <XXCoder> yeah
[16:44:18] <monttyle> I hoped it would be a lot more rigid for something small, than trying to make a parallel arrangement.
[16:44:55] <XXCoder> even more rigid would have that arrangements on both sides I bet thats possible
[16:45:09] <XXCoder> workspace would be square but 45 degrees rotated
[16:45:43] <XXCoder> but man very complex controls
[16:45:46] <monttyle> Hm, maybe. The shaft could just be done with a belt, but you couldn't do that with the captive motor.
[16:46:20] <monttyle> XXCoder: That's the beauty of it though -- the controls aren't that complex. One motor controls X linearly. And to change Y, you step one motor forwad, and the other twice back.
[16:46:42] <XXCoder> makes sense. double side other side would do opposite
[16:47:18] <monttyle> The control area could be made larger if it wasn't equilateral, I think, but then you really would need computer assistance to move everything all the time.
[16:47:49] <XXCoder> yeah bet you can figure it out
[16:48:18] <monttyle> Thanks. I had this horrible feeling I was missing something obviously wrong with it.
[16:55:59] <XXCoder> no problem
[17:06:14] <alex4nder> \
[18:05:21] <furrywolf> grrrr. mailman dropped off the sealed AGM battery I bought for one of the generators. the box has a big chemical burn hole in it. so does the padding. so does the inner box...
[18:05:51] <XXCoder> furrywolf: did you accept?
[18:05:58] <XXCoder> you can say no, I do not accept this
[18:06:14] <furrywolf> I was lying down. they dropped it off in front of the door.
[18:06:20] <XXCoder> oh darn
[18:06:24] <furrywolf> I didn't get up to get it until well after they were gone.
[18:06:46] <XXCoder> yeah complain to company maybe ship another one but delay jeez
[18:08:03] <furrywolf> aren't AGM batteries supposed to, you know, NOT eat holes through their packaging and into the other packages in the mail truck?
[18:08:35] <XXCoder> hmm yeah probably damaged other stuff and even van itself
[18:08:40] <XXCoder> er truck
[18:09:32] <XXCoder> lol https://www.youtube.com/watch?feature=player_embedded&v=cMvP49v7tOw
[18:09:38] <XXCoder> cheap way I guess
[18:10:30] <XXCoder> fur guy is using his lungs with airbrush painter
[18:10:41] <XXCoder> pretty good job from what I see.
[18:14:37] <SpeedEvil> furrywolf: I've started to do video unboxings of everything.
[18:15:15] <Jymmm> SpeedEvil: condoms?
[18:15:37] <XXCoder> if so, please dont film usage
[18:15:48] <Jymmm> XXCoder: hold on now...
[18:16:24] <Jymmm> XXCoder: SpeedEvil and partner might have special talents never before seen on TV
[18:16:44] <furrywolf> SpeedEvil: I did a photo still unboxing
[18:16:55] <Jymmm> furrywolf: animated gif?
[18:17:20] <XXCoder> one of best animated gif lol http://i.crackedcdn.com/phpimages/photoshop/3/4/0/374340.gif?v=1
[18:19:08] <Jymmm> http://mmbiz.qpic.cn/mmbiz/ecHjocgZldkvDQicmcwbQ3VEqaUuKWMpNk4T03J3adLFRJIpkKE8z3IHHz1iau6QbEKJ5pv8gLf9CiaukomcvtU9Q/0?tp=webp&wxfrom=5
[18:20:14] <furrywolf> under 1.5MB of images... should finish sometime today.
[18:26:22] <furrywolf> http://fw.bushytails.net/leakyagm/
[18:27:28] <XXCoder> dang
[18:27:33] <XXCoder> thats bad packaging.
[18:28:10] <XXCoder> the packaging is sad, and that's coming from guy who shipped packages everywhere
[18:28:34] <XXCoder> bad impact might have loosened the cover. is it repairable?
[18:29:07] <XXCoder> jy nice gif
[18:29:35] <furrywolf> no
[18:29:41] <furrywolf> and it never should have had free liquid in the first place
[18:29:55] <XXCoder> doble bonus fal
[18:29:57] <XXCoder> *fail
[18:30:03] <furrywolf> that's china's fail.
[18:30:50] <furrywolf> bbl
[19:20:43] <CaptHindsight> http://www.theguardian.com/technology/2015/jun/26/worlds-first-commercial-jetpack-next-year
[19:51:05] <redlegion> That's only fun if there are no safety features.
[19:54:00] <Jymmm> redlegion: lack of power resolves that
[19:55:03] <Jymmm> Now, why it tak ethem 35 years what NASA has had for 20?
[19:55:30] <Jymmm> First Responder, yeah, if they donate them.
[19:56:05] <Jymmm> If FR is a cop, then the bad guys just shoot em out of the sky?
[19:56:25] <Jymmm> If FR is medical, can it transport two ppl?
[19:56:59] <Jymmm> If Fire, you might have something there with an aerial fire house
[19:57:16] <Jymmm> hose*
[19:58:03] <Jymmm> but for what, dumpster fire?
[19:58:29] <Jymmm> Might be good for difficult recues
[19:58:47] <Jymmm> Still think a drone is better for SAR
[21:05:48] <zeeshan> what kind of nonsense is visual basic
[21:05:52] <zeeshan> there is no binary handling in it
[21:05:53] <zeeshan> lol
[21:06:02] <alex4nder> you need to load some DLLs
[21:06:08] <alex4nder> it fixes everything
[21:06:15] <zeeshan> really?
[21:06:24] <alex4nder> on Windows, everything can be done with a DLL
[21:06:37] <malcom2073_> Yeah, just google the dll name, and download the first result that comes up
[21:06:39] <malcom2073_> totally legit
[21:07:03] <XXCoder> vasic basic lol
[21:07:08] <XXCoder> it sucks
[21:07:18] <XXCoder> my first langange was basic, then vb 3.0
[21:07:31] <malcom2073_> The good ol days of vb
[21:07:55] <XXCoder> malcom2073_: yeah then ms tried to make it serious language. lol
[21:08:08] <malcom2073_> Heh, should've left it in the realm of small task scripting languages
[21:08:21] <malcom2073_> VB6 was so horrid, and everyone tried to write everything in it
[21:08:22] <malcom2073_> it's like python
[21:08:45] <XXCoder> vb6 is bad
[21:09:03] <XXCoder> vb5 isnt too bad
[21:09:08] <malcom2073_> You want to talk about a bad language? I'm doing stuff in LUA right now.... oh man
[21:09:30] <XXCoder> in least its not cobol or brainfuck lol
[21:09:36] <XXCoder> tried coding in latter, too hard lol
[21:09:40] <malcom2073_> It's like it was written by 5 different people, who all had *different* opinions on how to do *everything*
[21:09:59] <malcom2073_> So there are of course, 10 different ways of doing every single thing, each one of them with their own quirks
[21:10:12] <XXCoder> just like c++ and java
[21:10:21] <malcom2073_> I'm not talking higher level concepts
[21:10:46] <XXCoder> okay an example? making sute I understood
[21:10:59] <malcom2073_> array assignment
[21:11:07] <XXCoder> that basic?
[21:11:08] <XXCoder> dang
[21:11:13] <malcom2073_> So, you can have an array, and set values like myarray[1] = 1, myarray[2] = 25
[21:11:27] <malcom2073_> but then if you do my array[25] = 30, and try to count the number of items in the array
[21:11:34] <malcom2073_> you'll get 25
[21:12:10] <XXCoder> so only 1,2,25 was assigned but number of entries is now 25?
[21:12:16] <malcom2073_> And you can't actually remove an item
[21:12:19] <malcom2073_> Right
[21:12:29] <malcom2073_> To remove an item you set it to "nil". But it's stil actually there, and in memory, just set to nil
[21:12:42] <XXCoder> what happens if int x = myarray[4]
[21:13:03] <malcom2073_> Error. BUT! If you do myarray[2] = nil, you can do int x = myarray[2], and it exists
[21:13:08] <malcom2073_> So you have two types of nonexistant values
[21:13:22] <XXCoder> any way to probe and see if value exists?
[21:13:38] <malcom2073_> Yep, if (myarray[2] or nil == nil)
[21:13:44] <malcom2073_> that or makes it use nil, if it doesn't exist
[21:13:56] <XXCoder> interesting.
[21:14:28] <malcom2073_> So you can never actually remove items from an array, so be sure to reuse keys, because otherwise your indexes will get very large. But it's ok! Because they use doubles, so you'd never use them all!
[21:14:30] <XXCoder> " Multi-paradigm: scripting, imperative (procedural, prototype-based object-oriented), functional"
[21:14:30] <malcom2073_> *eyeroll*
[21:14:41] <XXCoder> lol
[21:15:04] <XXCoder> honestly I would add garbage collection for array
[21:15:15] <malcom2073_> I guess it's easier to use from the API side for integrating it into an application? It does make a pretty decent configuration scripting language, and the built in data serialization stuff is nifty
[21:15:17] <XXCoder> set to nil and it will move and reuse it for new array entry
[21:15:33] <malcom2073_> Oh! You want that? Guess what, 30 people have already written implementations for that, pick one.
[21:15:39] <XXCoder> fun
[21:15:39] <malcom2073_> You want classes? Another 30 options
[21:15:55] <malcom2073_> Ok I'm done ranting :P
[21:16:02] <XXCoder> lol yea
[21:16:12] <XXCoder> oh if you wanna good money, learn cobol
[21:16:18] <malcom2073_> haha I've heard
[21:16:21] <XXCoder> that stupid language will never die
[21:16:24] <malcom2073_> I'll stick to c++, I make good money with that for the time being
[21:16:35] <malcom2073_> And it's actually enjoyable
[21:16:37] <XXCoder> it will be around when captain kirk is around
[21:17:10] <XXCoder> and still around with time war future lol
[21:17:16] <malcom2073_> lol
[21:17:19] <XXCoder> seriously dunno
[21:18:19] <XXCoder> random tangent - I wish I could remember title but I really enjoyed this book on time travel - theres this group of humans from far future
[21:18:35] <malcom2073_> Heh
[21:18:46] <XXCoder> one day they found themselves in very advanced city, they know how to use everything, but they dont know anyone including themselves
[21:19:09] <XXCoder> so they worked together and try find what happened. just prior to that is time war and chaos so its hard
[21:19:21] <malcom2073_> Hmm
[21:19:42] <XXCoder> most of story is "present" but its interesting idea lol
[21:19:57] <malcom2073_> Wikipedia to the rescue maybe? https://en.wikipedia.org/wiki/List_of_time_travel_science_fiction
[21:22:23] <XXCoder> dunno maybe will find it, still looking
[21:22:30] <XXCoder> you should read light of other days though
[21:22:39] <XXCoder> not the romoatic one but sci fi one
[21:22:44] <XXCoder> two books same name jeez
[21:25:31] <XXCoder> The Accidental Time Machine is pretty good but not best
[21:28:11] <XXCoder> ahh the time ships. very very very good book
[21:28:22] <XXCoder> malcom2073_: its direct sequel to the time machine
[21:28:30] <XXCoder> the orginial and probably first time travel book
[21:29:14] <XXCoder> timescape, good classic one
[21:29:42] <XXCoder> morlock night never knew there was old sequel to the time machine too
[21:30:43] <malcom2073_> hmm
[21:30:45] <XXCoder> ahh not really direct sequel, and unauthorized
[21:30:47] <malcom2073_> So many books haha
[21:30:50] <malcom2073_> I'll add them to my list though
[21:31:04] <XXCoder> the time ships is long read
[21:31:08] <XXCoder> but yeah good
[21:31:43] <XXCoder> I suggest read classic story before reading time ships
[21:31:46] <XXCoder> get the picture
[21:33:04] <XXCoder> heh I remember short story on time travel
[21:33:25] <XXCoder> it has one odd rule, people can travel to future 100 years a time jumps
[21:33:40] <XXCoder> but backwards? over 1.5 million year a jump
[21:34:20] <XXCoder> probably got backwards years wrong but its very long time
[21:34:42] <XXCoder> they found facts on what happened 100 years future, but guess how they got information 100 years before
[21:35:17] <malcom2073_> Heh
[21:35:31] <XXCoder> figured it yet? lol
[21:35:40] <malcom2073_> Archeologists?
[21:35:49] <XXCoder> nah event happened in future
[21:35:59] <XXCoder> they could easily go 100 years then figure stuff out
[21:36:02] <XXCoder> but bring info back...
[21:36:13] <malcom2073_> Have to go *really* far
[21:36:17] <malcom2073_> then jump back
[21:36:18] <XXCoder> yeah
[21:36:23] <XXCoder> that they did
[21:36:48] <XXCoder> they reported kinda happy news of future 1.5 million minus 100 years
[21:36:54] <malcom2073_> nice
[21:36:56] <malcom2073_> bedtime for me, night!
[21:36:56] <XXCoder> world was returning to life lol
[21:37:07] <XXCoder> night :)
[21:37:38] <XXCoder> furrywolf: how goes things
[21:55:58] <PetefromTn_> any of you guys know anything about source filmmaker program?
[21:58:27] <XXCoder> sorry
[21:58:41] <XXCoder> whats you planning? if not secret plan lol
[22:00:20] <PetefromTn_> no secret my oldest daughter wants to learn to use it and it apparently must download something called steam before you can download the program. Not sure what the affiliation is but the steam program is a PIG and is slow as hell loading and other issues.
[22:01:03] <XXCoder> isnt stream gaming
[22:01:07] <XXCoder> oh steam
[22:03:14] <zeeshan> yay
[22:03:21] <zeeshan> only thing left is temp interface
[22:03:24] <zeeshan> pressure seems to be working
[22:03:38] <zeeshan> http://i.imgur.com/bITJ4Fv.jpg
[22:03:40] <zeeshan> what a mess of a wiring job
[22:03:41] <zeeshan> :)
[22:03:53] * zeeshan has no zip tie mounts here
[22:04:11] <Tom_itx> gawd what a sucky wiring job! ;D
[22:04:29] <XXCoder> cnc control stuff?
[22:04:40] <Tom_itx> i'm just being agreeable...
[22:05:03] <XXCoder> Tom_itx: was asking zee
[22:05:14] <Tom_itx> i know
[22:05:21] <XXCoder> :P ok lol
[22:05:50] <zeeshan> XXCoder: nahh expertimental appratus
[22:05:53] <zeeshan> for school
[22:05:57] <Tom_itx> why the mix of plastic and copper tubing?
[22:06:07] <XXCoder> cool
[22:06:30] <zeeshan> Tom_itx: couldnt find fittings for copper tube
[22:06:44] <zeeshan> 10-32 ones that is
[22:07:47] <Tom_itx> is that your heater box?
[22:07:57] <Tom_itx> looks like it's starting to take shape
[22:09:19] <zeeshan> temp and pressure control
[22:09:22] <zeeshan> pressure 0 - 50 psi
[22:09:30] <zeeshan> temp -20 to 260C
[22:09:44] <Jymmm> i see usb thingy on it
[22:10:42] <XXCoder> interesting
[22:10:49] <XXCoder> is there ultimate use for this?
[22:10:57] <XXCoder> or a class project?
[22:11:00] <zeeshan> biaxial tensile testing
[22:11:04] <zeeshan> thermforming testing
[22:11:05] <zeeshan> etc
[22:11:08] <XXCoder> ahh cool
[22:11:11] <zeeshan> thesis
[22:11:21] <XXCoder> engineering?
[22:12:33] <Jymmm> whats the red/wht/blk wire thingy
[22:13:20] <Tom_itx> probably pressure sensor
[22:13:22] <Tom_itx> or temp
[22:13:52] <zeeshan> pressure transducer
[22:14:12] <zeeshan> the temp garbage is the umbilical coming from the environmental chamber
[22:14:18] <zeeshan> i gotta hook them up still
[22:14:23] <zeeshan> i have a very basic interface for it right now
[22:14:53] <Jymmm> zeeshan: whats the usb thingy?
[22:15:00] <zeeshan> daq
[22:15:03] <zeeshan> along with gpio
[22:15:09] <zeeshan> 14bit
[22:15:09] <XXCoder> zeeshan: hey can you come over and help me finish my cnc router? lol
[22:15:10] <Jymmm> link?
[22:15:30] <zeeshan> http://www.mccdaq.com/usb-data-acquisition/USB-1408FS-Plus.aspx
[22:15:33] <zeeshan> XXCoder: lol
[22:15:51] <zeeshan> i couldnt get it to work on linux
[22:15:52] <zeeshan> their drives
[22:15:53] <XXCoder> its on hold while my uncle mills grooves on motor mounts lol
[22:16:00] <zeeshan> so im resorting to wingay
[22:16:07] <zeeshan> im writing crap oin visual basic
[22:16:13] <zeeshan> something ihavent used oin like 20 years
[22:16:18] <zeeshan> :(
[22:16:20] <Jymmm> zeeshan: does it record when NOT connected to computer?
[22:16:22] <zeeshan> i wanted to use sexy glade
[22:16:26] <zeeshan> Jymmm: no
[22:16:30] <zeeshan> no on board ram
[22:16:44] <Jymmm> zeeshan: bummer. Nice job on your project =)
[22:16:50] <renesis> ha VB
[22:17:09] <renesis> i had to script an audio aquisition system in visual basic, sucked
[22:17:36] <Jymmm> zeeshan: I think you need BIGGER diodes though ;)
[22:18:02] <zeeshan> thank u
[22:18:06] <zeeshan> 6a1 aint big enough?!?!
[22:18:13] <XXCoder> project rule - every project costs more and time than budgeted for, even with this rule factored in
[22:18:19] <Jymmm> zeeshan: og course not silly
[22:18:42] <Jymmm> zeeshan: room sized diodes are the best
[22:19:32] <renesis> i like the ones with braided metal straps and 1/4" ring terminal on one side, big threaded stud for the other terminal
[22:19:45] <Jymmm> EXACTLY
[22:20:15] <renesis> i kept finding those in old bins at one job, then one day boss dork is like HEY FIX THE MEGNETIZER WERE SENDING IT TO CHINA
[22:20:22] <renesis> im like, hahaha no
[22:20:43] <renesis> not fucking with a bank of 40 year old caps if they need bunch of diodes that big
[22:21:28] <renesis> take out a dudes knee easy with them
[22:21:43] <Jymmm> zeeshan: http://www.highpowersemiconductors.com/admin/uploads/semiconductors/thumb_1888.jpg
[22:21:55] <Jymmm> zeeshan: that'll impress em!
[22:21:57] <zeeshan> i aint building a power supply!
[22:22:25] <XXCoder> its not a serious project unless you need forklift to move it :P
[22:22:25] <renesis> jymmm: yeah thats it
[22:22:33] <Jymmm> zeeshan: Coem on man, any time you can install a diode using a 1/2 socket you DO IT!!!
[22:29:27] <zeeshan> any suggestions on how to test an analog out
[22:29:31] <zeeshan> without a scope
[22:29:48] <XXCoder> light?
[22:29:55] <XXCoder> seriously dunno
[22:33:30] <XXCoder> wb
[22:45:38] <RyanS> my stupid Chinese lathe's tailstock quill doesn't reach the tip of the tool, its crazy. how would i address that?
[22:46:56] <RyanS> If i used 5C collets i would not be able to drill
[22:59:21] <zeeshan> what do you mean
[22:59:30] <zeeshan> tip of what tool?
[23:34:13] <jesseg> hey guys. Is there a cable available for servo motors - i.e. 2 or 3 thicker conductors inside a shield for the motor windings then a couple of small coax wires for the quadrature encoders?
[23:34:57] <cradek> they tend to be separate cables
[23:35:21] <jesseg> Ahh OK. What about a cable that's got two little coax's and a power lead for the encoder?
[23:35:40] <cradek> you don't use coax for encoders
[23:35:48] <cradek> encoders are generally differential, so you use twisted pairs
[23:36:06] <jesseg> well, what if you're on a budget and the encoders you have don't have differential outputs? :P
[23:36:33] <cradek> I've seen folks add differential drivers at the encoder
[23:36:33] <jesseg> "Get off the budget?" :D
[23:36:38] <jesseg> ahh OK
[23:36:42] <cradek> us digital even has little dongles that do that for you
[23:37:15] <RyanS> zee.... cutting tool, in the toolpost, so can't machine up to the dead center
[23:37:20] <cradek> you can try it without of course, and use a suitable time constant RC filter at the receiving end
[23:37:44] <cradek> it might work, especially if you keep the encoder lines away from the power lines
[23:38:37] <cradek> as your speeds get fast or your resolution gets high, an RC filter will round off and kill the signal, and you'll need differential
[23:38:38] <jesseg> I find small coax (i.e. 2.5mm, etc) to work pretty well for the encoder signals over some distance. Otherwise they pick up too much transients from the switching signal going to the motor or even from the other encoder channel
[23:38:40] <cradek> so ... it depends
[23:39:27] <ffurrywol> http://www.ebay.com/itm/Igus-Chainflex-VFD-Servo-cable-CF21-15-15-02-01-16-Gauge-power-signal-10-ft-/221263730386
[23:39:30] <cradek> I'm surprised ttl-output encoders will drive coax, but I don't know much about transmission like that
[23:39:54] <RyanS> It seems like the only fix is to make a longer tailstock leadscrew and ram
[23:40:15] <ffurrywol> the tailstock on my shoptask only has like 1" of travel.
[23:40:33] <cradek> ffurrywol: can't run much of a servo on 16 gauge wire can you?
[23:41:24] <jesseg> ffurrywol, wow cool! So they have thought of it. Not exactly the configuration I'm wanting but at least I know they thought of it!
[23:41:27] <RyanS> ffurrywol so how do yo machine with a dead center?
[23:41:33] <cradek> http://www.usdigital.com/products/interfaces/encoder/cable-drivers/pc4
[23:41:43] <cradek> $15.70 qty 1
[23:42:13] <furrywolf> jesseg: I think all the control cable manufacturers have cables with bundled shielded encoder wires.
[23:42:23] <furrywolf> I just pasted that one because I got some a while ago. :)
[23:42:54] <jesseg> furrywolf, cooool. "Control cable" - maybe that's what I need to search for. I just don't knwo the right terms
[23:43:09] <RyanS> the ram and screw needs to be hardened, right?
[23:43:20] <furrywolf> you can also just look for "servo cable" :)
[23:43:24] <jesseg> I guess if I used differential drivers, then I could just use cat5e :P
[23:43:45] <furrywolf> RyanS: you need more than an inch for a center? it's only annoyed me when trying to drill, bore, etc.
[23:45:18] <furrywolf> jesseg: as a warning, if you buy retail, such cables are NOT CHEAP.
[23:45:41] <furrywolf> plan $5-$10+/ft
[23:45:45] <RyanS> furrywolf well , I want to machine the entire length of the part right up to the dead centre.... I can't get the tool to reach no matter which way I orient the compound & tool post
[23:46:08] <furrywolf> I got a MT3 extension sleeve for problems like that
[23:46:40] <furrywolf> you'd obviously want one for whatever taper you have. :)
[23:46:47] <RyanS> mt3->mt3 ?
[23:47:09] <furrywolf> yes
[23:47:34] <furrywolf> like http://www.smithy.com/accessories/NDItMDEz
[23:47:39] <jesseg> furrywolf, yeah figures. I'll probably just use cheap thin coax for the encoders and see how that works. Same number of conductors, and no need to get line drivers.. however, I now wish that when I designed the servo board I'd used differential inputs :P
[23:47:53] <furrywolf> "Use this extension to give yourself some breathing room on the tailstock end of the lathe. If you are working with small lengths, you can use the extension socket to extend your tailstock set-up. This hardened steel socket with tang will add 3-1/2” to your set-up."
[23:48:40] <RyanS> hmm, I thought theres only mt4->3, 3->2.... This makes things easier
[23:49:23] <furrywolf> http://shopmasterusa.com/tools-complete-list/290-m3-m3-morse-taper-extension.html is the exact one I got.
[23:49:44] <furrywolf> (I have a shopmaster machine, was purchasing other stuff from them, and they have about the cheapest price anyway)
[23:51:30] <jesseg> Thanks guys!
[23:53:49] <furrywolf> of course, if you don't have a mt3 tailstock, don't get the mt3 extension I pasted. :)
[23:54:43] <RyanS> I love Australian prices, http://www.machineryhouse.com.au/D402
[23:55:04] <RyanS> and sarcasm :)
[23:56:08] * furrywolf doesn't remember the AUD being 1/5th the USD...
[23:56:20] <alex4nder> RyanS: australia was a prison colony
[23:56:31] <alex4nder> so they price everything like you're buying cigarettes in jail
[23:56:32] <RyanS> Why would you want to extend the length if anything apart from a tail stock?
[23:56:51] <RyanS> ...right
[23:57:24] <RyanS> its not 1820 anymore
[23:57:33] <alex4nder> have you been to australia?
[23:57:39] <furrywolf> my mill only has 3" of Z travel, with shorter cutting tools not making it near the table. part of why I have one is for extending the tools so they reach the table. I haven't yet used it for this however.
[23:57:41] <alex4nder> the only thing cheap there is the cellphone plans
[23:57:53] <RyanS> I am Australian
[23:57:57] <alex4nder> RyanS: then you understand
[23:58:25] <alex4nder> last time I was in Perth, I paid 30 AUD for an old fashioned
[23:58:35] <RyanS> but it's not because we were a convict colony
[23:59:00] <furrywolf> don't you keep stealing our ozone? :)
[23:59:14] <RyanS> economy of scale
