[01:35:42] <SpeedEvil> :) :(
[01:38:12] <furrywolf> made an appointment for an alignment saturday... it's pretty hard to drive right now. pulls badly, wobbles, doesn't track at all.
[01:39:06] <furrywolf> takes continual force on the wheel to keep the car going straight, which is a bad combination with having back pain...
[01:40:41] <SpeedEvil> Sounds like you need an alignment too. Maybe they'd do a two for one.
[01:41:02] <SpeedEvil> At least you're sort-of-mobile now.
[01:41:24] <SpeedEvil> Hopefully by monday it'll be improving a little.
[01:42:26] <furrywolf> I don't think it works that way.

[01:46:11] <zeeshan-laptop> does anyone know
[01:46:24] <zeeshan-laptop> how the heck to get debian packages along with all the dependencies
[01:46:29] <zeeshan-laptop> in one pkg.
[01:46:31] <zeeshan-laptop> im trying to do this in windows
[01:46:54] <furrywolf> on windows? no clue
[01:47:05] <Tom_itx> why are you doing it the hard way?
[01:47:07] <furrywolf> also, "all dependencies" might be most of a complete install
[01:47:21] <furrywolf> since it eventually depends on bash, libc, etc.
[01:47:41] <Tom_itx> zeeshan-laptop is this a rtai ver?
[01:47:44] <zeeshan-laptop> no
[01:47:47] <zeeshan-laptop> its jessie
[01:47:55] <zeeshan-laptop> the fucking internet doesnt work on this pos
[01:47:56] <Tom_itx> just get the iso
[01:47:59] <zeeshan-laptop> setupid garbage
[01:48:05] <zeeshan-laptop> Tom_itx: im trying to download this pkg
[01:48:23] <zeeshan-laptop> https://packages.debian.org/jessie/libfox-1.6-dev
[01:48:29] <zeeshan-laptop> its got a crapload of dependencies
[01:48:31] <zeeshan-laptop> most of which i dont have
[01:48:39] <zeeshan-laptop> i tried downloading some
[01:48:44] <Tom_itx> keep apt-getting them until you do
[01:48:45] <zeeshan-laptop> and it started complaining im missing more packages lol
[01:48:50] <zeeshan-laptop> im in windows..
[01:48:57] <zeeshan-laptop> theres no internet on the deb comp
[01:49:02] <zeeshan-laptop> (im at school)
[01:49:08] <furrywolf> put internet on the deb computer?
[01:49:15] <zeeshan-laptop> i cant get their wireless to work.
[01:49:21] <zeeshan-laptop> it requires some retarded nonsense that doesnt work
[01:49:27] <Tom_itx> swap hdd out until you got what you need
[01:49:28] <zeeshan-laptop> i followed their instructions word for word
[01:49:39] <Tom_itx> WORD for WORD!
[01:49:42] <zeeshan-laptop> !!
[01:50:00] <furrywolf> what does it require other than "connect to access point and get IP"? lol
[01:50:02] <Tom_itx> i feel like i'm keeping mesa in business lately
[01:50:16] <Tom_itx> (i know i'm not but...)

[01:50:58] <tiwake> stupid
[01:51:04] <zeeshan-laptop> that is what i followed
[01:51:07] <furrywolf> I wish I could give pcw money. :(
[01:51:13] <tiwake> ruined 3 of the 6 parts by cutting a key off center
[01:51:49] <Tom_itx> tiwake the thing about cnc is that you can make them all good or all bad
[01:52:15] <tiwake> 6 parts is just enough for the kind of part to make it in the CNC
[01:52:26] <tiwake> but I don't have any more material
[01:53:48] <Tom_itx> furrywolf you're wanting pci boards aren't you?
[01:54:02] <furrywolf> did you enter MacID like the text says or macid like the image says? lol
[01:54:08] <furrywolf> Tom_itx: no. ethernet.
[01:54:14] -!- MacGalempsy has quit [Remote host closed the connection]
[01:54:18] <furrywolf> I have no systems with pci (or pcie) anymore.
[01:54:51] <zeeshan-laptop> yes
[01:54:52] <zeeshan-laptop> :P
[01:55:38] <furrywolf> it does seem like pointless bullshit to make you need weird authentification (I've never even heard of that) with a publicly available username and password.
[01:56:43] <zeeshan-laptop> just gonna download manuall.y..
[01:56:44] <zeeshan-laptop> so lame
[01:56:45] <zeeshan-laptop> :P
[01:58:27] <furrywolf> I got a muffler on the project subaru today
[01:58:39] <zeeshan-laptop> nice
[01:58:45] <zeeshan-laptop> got a lot to do to get it running?
[01:59:28] <furrywolf> it's running fine...
[01:59:28] <furrywolf> it needs an alignment, badly. it's not going to align without modifications, but at least it'll be closer.
[01:59:46] <furrywolf> the radiator fans suck, need to replace them. I used dual little fans, need to modify the body and put in one big one.
[01:59:54] <furrywolf> has no heat or a/c

[02:00:37] <PetefromTn_> Does that look like it has constant current control to you guys?
[02:00:51] -!- MacGalempsy [MacGalempsy!~quassel@ip72-204-45-74.fv.ks.cox.net] has joined #linuxcnc
[02:01:20] <Tom_itx> looks like it may
[02:01:22] <furrywolf> need to do a few wiring changes, and a working oil pressure gauge would be nice. (right now I have a better-than-useless one, but not nearly as useful as it could be... the gauge reads 75PSI when there's <5PSI, and 0PSI when there's >5PSI)
[02:01:49] -!- creyc [creyc!~creyc@96-59-51-101.res.bhn.net] has parted #linuxcnc
[02:01:52] <furrywolf> that is, during normal driving, it reads 0, and if it reads anything other than 0, something is wrong.
[02:02:08] <PetefromTn_> The one that Capt recommended actually says it and this one kind of hints at it. That one is considerably cheaper but it is only 10 amps instead of the 20 amps of the other one.
[02:03:14] <PetefromTn_> http://www.anodizeworld.com/power-supply.html This website Captainhindsight linked the other day sells a very similar lower power unit and it says they anodize with it a lot in the text..
[02:03:33] <furrywolf> it has both fine and coarse current controls
[02:03:59] <PetefromTn_> Just wondering if I can go with the lower priced unit without sacrificing too much
[02:04:21] <furrywolf> my lambda has fine voltage but no fine current.
[02:04:37] <furrywolf> "The output current is between 0 and nominal value continuously adjustable"
[02:05:12] <PetefromTn_> yeah not sure if that means it is continually adjustable MANUALLY or automatically once set...
[02:05:51] <furrywolf> it means manually, since it has knobs for it...
[02:06:12] <furrywolf> it's always "automatic", in that it won't maintain constant current once you reach the voltage setpoint
[02:06:13] <PetefromTn_> then it is NOT constant current control I suppose
[02:06:34] <furrywolf> ?
[02:07:13] <furrywolf> what you set with the knobs are limits for the voltage and the current. neither will be exceeded, and the output will always be at either the voltage setpoint or the current setpoint.
[02:07:31] <PetefromTn_> the point being that as the anodize layer builds on the part in the acid tank the resistance to the charge increases. The current must then increase to account for the thickening of the layer for best results.
[02:08:17] <PetefromTn_> The constant current feature apparenlty works this way
[02:08:27] <PetefromTn_> I am not sure if this unit is capable of this or not.
[02:08:34] <furrywolf> with no load, the output will be the voltage setpoint. if you increase the load, it will regulate that voltage as the current rises. once you increase the load until the current rises to the current setpoint, it will regulate the current and the voltage will fall below the voltage setpoint.
[02:08:36] <PetefromTn_> If it is I will probably buy it.
[02:08:57] <furrywolf> if you keep increasing the load, the current will stay constant, and eventually the voltage will drop to 0 when you short-circuit it.
[02:09:25] <furrywolf> yes, that unit will do that, as long as the voltage setpoint is higher than the maximum voltage you need to maintain the current.
[02:10:22] <furrywolf> a constant voltage / constant current power supply can't do both at once - it would violate ohm's law. it switches between voltage regulation and current regulation based on the load.
[02:11:26] <PetefromTn_> http://www.automationtechnologiesinc.com/products-page/mastech-power-supply/mastech-hy3020d This one is supposedly constant current/Constant Voltage controlled
[02:11:35] <alex4nder> furrywolf: unless it warps space time to modify the load
[02:11:38] <furrywolf> many supplies have an indicator to tell you if it's in CV or CC mode.
[02:11:41] <alex4nder> check .. mate
[02:12:01] <Jymmm> furrywolf: Unless it is ONE wiht the universe =)
[02:12:25] <Jymmm> furrywolf: Hey, you do any PB / pex plumbing?
[02:12:43] <furrywolf> PetefromTn_: think of the voltage and current settings as limits... it'll put out as much as it can until it hits one limit or the other.
[02:13:19] <alex4nder> that sounds like a welding power supply
[02:13:27] <furrywolf> Jymmm: lead? no. :P
[02:13:31] <furrywolf> pex... a little.
[02:13:47] <Jymmm> FinboySlick: PB = Poly butelne
[02:13:59] <Jymmm> polybutylene
[02:14:00] <furrywolf> yes, I know...
[02:14:04] <furrywolf> but I haven't done any of it.
[02:14:21] <Jymmm> well you mentioned lead, but gotcha
[02:15:07] <furrywolf> Pb = lead
[02:15:10] <FinboySlick> Huh?
[02:15:49] <Jymmm> the OTHER classactionlawsuit pb =)
[02:15:53] <furrywolf> FinboySlick: he meant to address me, but didn't type enough correct letters.
[02:16:17] <FinboySlick> Oh sure, you get all the attention.
[02:16:26] <Jymmm> FinboySlick: Yeah, all you F's look alike!
[02:16:41] <furrywolf> that's because I'm fluffy instead of slick. don't use so much hair gel. :P
[02:16:52] <Jymmm> heh
[02:17:42] <FinboySlick> Pff, dog with a delusion of grandeur and overdeveloped sense of romanticism.
[02:19:57] <FinboySlick> Jymmm: You heard of TIS-100, btw?
[02:20:13] <SpeedEvil> http://finari.arc.nasa.gov/learnseminar2013 - as a general link.
[02:20:14] <Jymmm> FinboySlick: nope
[02:20:52] <FinboySlick> Cool little game. You have to 'fix' modules in an odd sort of parallel computer. It's assembler, the game.
[02:21:00] <SpeedEvil> err
[02:21:02] <SpeedEvil> http://nari.arc.nasa.gov/learnseminar2013
[02:21:19] <FinboySlick> Up to 12 CPUs, each with a single register. There's about 20 instructions.
[02:21:25] <Jymmm> FinboySlick: heh
[02:21:31] <SpeedEvil> This has funky stuff like how to make carbon nanotube functionalised carbon tubes in the microwave in 30 seconds
[02:21:38] <Jymmm> FinboySlick: I like Brainfuck though =)
[02:21:43] <alex4nder> haha
[02:22:06] <Jymmm> FinboySlick: BF is much liek RPN in a sense
[02:22:07] <FinboySlick> The level I'm currently struggling with is implementing a signal pattern detector.
[02:22:15] <SpeedEvil> And helicopters without swashplates powered by aerodynamic pumping
[02:22:48] <alex4nder> FinboySlick: you need a greenarrays dev board
[02:23:27] <FinboySlick> alex4nder: Nah. I'm pretty sure I'll have my fill once I've beaten this game.
[02:23:52] <FinboySlick> It's quite fun though. Runs natively on linux too.
[02:25:06] <furrywolf> on the internet, no one knows you're a dog... so you have to tell people. :P

[02:27:30] * SpeedEvil assumes furrywolf owns a chainsaw.
[02:27:44] <Jymmm> SpeedEvil: just a 20ton log splitter
[02:27:46] <SpeedEvil> Err - no - female dogs are bitches at all times.

[02:34:14] <furrywolf> ... the first? I'm sure sherline, taig, etc might disagree.
[02:34:52] <FinboySlick> I saw this a little while back, I think it's a nice design.
[02:36:55] <furrywolf> sherline may not sell a 5-axis mill complete, but they sell all the bolt-together parts needed to assemble one in ten minutes.

[03:02:35] <Rab> renesis, not at all...depending on the tooth profile.
[03:03:50] <Rab> In that application they're pretty short, too.
[03:03:56] <SpeedEvil> And the composition.
[03:04:11] <SpeedEvil> glass fibre reinforced belts can be really quite stiff

[06:30:37] <Crom> it's a freenode thang... when you show up it's morning, when you leave it's night.. FREENODE standard time
[06:31:33] <norias> fair
[06:32:00] <norias> went on visit to a company called Exone today
[06:32:09] <norias> they make a line of 3d printers for metal
[06:32:19] <norias> and sand (for aluminum casting)
[06:32:23] <norias> neat stuff
[06:32:40] <Crom> nice sintered? or epoxy binding?
[06:33:30] <norias> i'm going to say... uh. sintered
[06:33:33] -!- podarok [podarok!~podarok@host-176-38-13-39.la.net.ua] has joined #linuxcnc
[06:33:59] <Crom> sintered is laser melts particles together
[06:34:16] <norias> well, so these parts get sintered in an oven
[06:34:39] <norias> powder held together with binder
[06:34:45] <norias> binder gets cooked out in oven
[06:35:04] <norias> so, a bit like traditional powdered metal in that sense
[06:35:14] <Crom> expoxy then... using a inkjet type spray nozzle
[06:35:26] <norias> right
[06:35:42] <norias> sounds like off terminology to me
[06:35:48] <norias> since the parts do get sintered
[06:35:54] <norias> just not with a laser

[06:37:54] <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
[06:38:18] <norias> right
[06:38:30] <norias> at that stage of the game
[06:38:38] <norias> it's the same thing as powdered metal process
[06:38:58] <norias> really, it is a powdered metal process
[06:39:07] <norias> just a different way to get there with binder, etc
[06:40:02] <Crom> sintered is a laser causes the powder to barely melt and stick together. no binder.
[06:40:28] <norias> that's not the only way to sinter
[06:40:36] <Crom> you can then place it into an oven and wick in the solder/bronze to fill the voids
[06:42:06] <Crom> ruger would make the MKI using sintered melted powder then heat it to melt together in a ceramic mold

[06:43:23] <norias> yeah
[06:43:34] <norias> i used to work in a place that did the same thing
[06:43:39] <norias> but with tungsten carbide
[06:44:01] <norias> you do it in a HIP furnace
[06:44:07] -!- Mr_Sheesh [Mr_Sheesh!~mr_s@unaffiliated/mr-sheesh/x-0757054] has joined #linuxcnc
[06:44:08] <norias> argon gas under pressure
[06:44:41] <norias> sometimes the preforms are done in compacting dies
[06:45:02] -!- Mr_Sheesh has quit [Excess Flood]
[06:45:11] <norias> we machined the preforms before they got sintered
[06:45:19] <norias> which was a bit of a delicate process
[06:45:28] <norias> they used a wax of some sort as the binder
[06:46:21] <norias> i think it was cold isostatic pressing
[06:46:35] <norias> of maybe 6-7 generic forms
[06:46:49] <norias> which we machined to near neat (plus shrink factor)
[06:46:52] <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
[06:47:00] <norias> then they went in the HIP

[06:47:20] -!- Deejay [Deejay!~Deejay@unaffiliated/dj9dj] has joined #linuxcnc
[06:47:23] <norias> after 90% ish density
[06:47:25] <Deejay> moin
[06:47:31] <norias> the difference is kinda academic
[06:47:49] <norias> you don't _have_ to fill with bronze
[06:47:57] <norias> you can leave it porous
[06:48:16] <norias> and in industrial applications they do, unless you need it to be air/water tight
[06:48:41] <norias> density is also partially controlled by material
[06:48:46] <Crom> true... I'd rather fill with bronze, makes it alot more ductal
[06:49:05] -!- Mr_Sheesh has quit [Excess Flood]
[06:49:08] <norias> hmm. does it really?
[06:49:28] <norias> at that point it's a matrix who's ductility is mostly controlled by the bulk material
[06:49:44] <norias> Wc is that way
[06:50:00] <norias> it's a matrix of tungsten and either cobalt or ...
[06:50:07] <norias> dang, i forget

[06:50:18] <norias> nickel
[06:51:57] <Crom> yepI'm thinking stainless or carbon steel. bronze infill reduces quite a bit of the snappiness um.. what's the word
[06:52:21] <Crom> not crystaline
[06:53:21] <norias> lower hardness
[06:53:25] <norias> higher toughness
[06:53:49] <norias> although, i don't think the increase in toughness is necessarily...
[06:53:55] <norias> the normal mechanism
[06:54:03] <norias> but i'm not totally sure there
[06:55:55] <Crom> like a M1911 slide. straight sintered works well for .45acp, you probably want infiltration on a .45 win mag slide
[06:59:51] <norias> well, shit

[11:38:47] <lottefang> Hello linuxcnc community !
[11:40:36] <lottefang> Could any one explain why linuxcnc has both acceleration/deceleration mechanism in control.c and stepgen.c?
[11:40:50] -!- per_sonne has quit [Ping timeout: 246 seconds]
[11:41:22] <archivist_herron> because its needed for any mechanical system to avoid overshoot
[11:42:20] <pcw_home> and the stepgen component can be used independetly of motion
[11:48:37] <lottefang> Well then, where is the keypoint to let the stepgen component run under the control.c's way?
[11:51:07] <MarkusBec> i think its because you dont need stepgen to control the cnc
[11:51:36] <pcw_home> typically if something outside the stepgen limits accel you either disable accel limits in the stepgen (accel=0)
[11:51:38] -!- mhaberler has quit [Quit: mhaberler]
[11:51:38] <pcw_home> or set the stepgen accel to say 20% higher than the maximum commanded accel
[11:51:56] <MarkusBec> and you can use stepgen for other purposes than move the cnc
[11:52:30] <pcw_home> a torch height control is one example
[11:59:00] <lottefang> Thanks guys! I thinks i understand now.
[12:01:41] <pcw_home> Its arguable the velocity /accel limits should not be in the stepgen but
[12:01:42] <pcw_home> instead use the limit2 or limit3 comp in those cases where the stepgen is
[12:01:44] <pcw_home> not used with the TP
[12:03:03] <pcw_home> but its tedious to string all those hal comp beads together for common ops

[13:12:31] <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,...
[13:13:09] <shaun413> no, just a mount by the spindle
[13:13:14] <shaun413> to connect to a shopvac

[14:45:25] <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.
[14:45:33] <renesis> from your link
[14:46:35] <norias> waking up is hard to do
[14:47:02] <pcw_home> there are no positive resistances over arbitrarily wide ranges of current either
[14:48:19] <renesis> look man i can buy a resistor with positive values at digikey
[14:48:25] <renesis> i cant buy them in negative values
[14:48:46] <renesis> maybe they are just out of stock, but that still means they dont exist
[14:48:50] <CaptHindsight> renesis: it just open up an interesting discussion since they chose "negative resistance" as the name for the effect
[14:49:02] <CaptHindsight> open/opens
[14:49:17] <pcw_home> no but you can buy a neon bulb that exhibits negative resistance
[14:49:23] <renesis> a lot of circuits have negative resistance properties

[14:50:42] <renesis> dont you have to like, spark a neon bulb off?
[14:51:25] <renesis> its not like you put a psu and a resistor and all of a sudden voltage across the resistor reverses
[14:51:30] <CaptHindsight> _methods: on another note investors have filed suit against 3D systems for inflating their forecasts on sales and profits
[14:51:38] <CaptHindsight> the great hype machines
[14:51:40] <renesis> hmm actually i think in some cases it does
[14:51:52] <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
[14:52:04] <t12> 3d printing... pure enthusiasm
[14:52:07] <pcw_home> = negative resistance
[14:52:18] <furrywolf> you can buy positive resistances for any current you want, as long as you don't mind a reduction in duty cycle.
[14:52:36] <CaptHindsight> http://3dprintingindustry.com/2015/06/16/investors-seek-class-action-lawsuit-against-3d-systems-for-weak-earnings/
[14:52:36] <renesis> right but i think that has to do with the lowered resistance due to the larger arc
[14:52:48] <pcw_home> well HV breakdone is possible
[14:53:01] <t12> wait till someone does the math on makerbot
[14:53:02] <renesis> i thought thats how they worke?
[14:53:07] <t12> wasnt it about a 500m buyout
[14:53:23] <CaptHindsight> t12: those were still actually selling
[14:53:24] <renesis> you overcome the gas resistance, start an arc, and the plasma is a lower resistance
[14:53:31] <renesis> im just guessing tho
[14:53:35] <CaptHindsight> since they are low cost
[14:54:07] <pcw_home> no you can plot the voltage vs current and you get a negative slope
[14:54:41] <renesis> right because more current is a bigger arc is less resistance is less voltage

[14:56:06] <renesis> pcw_home: yeah i imagine its a weird feedback loop and changes with temp, shrug
[14:56:15] <renesis> a battery is a negative resistance
[14:56:16] <pcw_home> negative resistance without a equal or greater positive resistance makes an oscillator
[14:56:20] <malcom2073_> shaun413: You bolt things down with them
[14:56:32] <shaun413> how malcom2073_ ?
[14:56:34] <malcom2073_> shaun413: Play with them until you figure out a way that works, there are only so many ways you can use them
[14:56:55] <pcw_home> (maybe only one cycle if you dont limit the current)
[14:56:59] <malcom2073_> You put a bolt through the hole, screw it into a nut on your table, and put the piece under it?
[14:57:00] <shaun413> ive tried for 30 mins
[14:57:03] <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
[14:57:17] <shaun413> yeah malcom2073_ it wont tighten enough to clamp if i do that
[14:57:31] <malcom2073_> shaun413: The bolts break if you tighten more?
[14:57:33] <renesis> from the input of the circuit, ya its negative resistance, but thats not the whole system
[14:57:37] <malcom2073_> What do you mean won't tighten enough?
[14:57:40] <furrywolf> those are best used with step blocks. if you don't have step blocks, use random spacers.
[14:57:42] <shaun413> they hit the bottom
[14:58:00] <furrywolf> also, that's the most piss-poor accessory kit I've ever seen.
[14:58:07] <malcom2073_> Use washers on the bolts so they don't hit bottom
[14:58:09] <shaun413> step blocks?
[14:58:21] <malcom2073_> shaun413: I hope your work didn't pay more than $900 for that thing
[14:58:30] <furrywolf> pot metal wrenches, holddowns with insufficient parts,...
[14:58:35] <shaun413> idk what they paid malcom2073_ its shit

[15:00:23] <malcom2073_> As are the bearings

[15:00:40] <shaun413> :p
[15:00:40] <malcom2073_> But it makes an alright wood/plastic cutting machine
[15:00:42] <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.
[15:00:45] <shaun413> shouldnt gottan a probotix

[15:01:23] <shaun413> ok
[15:01:52] <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.
[15:01:57] <shaun413> furrywolf, i would if i had washers and nuts...
[15:02:21] <furrywolf> if you don't have a random assortment of washers and nuts, you're not qualified to operate a milling machine.

[15:03:59] <shaun413> can I literally just duct tape it down for now?
[15:04:08] <malcom2073_> You could hold it down with your fingers

[16:35:50] <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.

[16:41:20] <Jymmm> renesis: Just SOEMTHING, anything better than tar shingles
[16:41:55] <Jymmm> silicone stick to pretty much everything; would seem easy to patch/repair
[16:42:21] <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.

[16:51:00] <shaun413> i cut a perfect circle :P
[16:51:02] <furrywolf> if I had to build a new house with a new roof, I'd use metal roofing. seems to last roughly forever.
[16:51:06] <Rab> shaun413, excellent!
[16:51:25] <furrywolf> Jymmm: because the roofing industry needs to stay in business.
[16:51:30] <shaun413> thanks
[16:51:40] <shaun413> now to try something more interesting?
[16:51:43] <furrywolf> if they sell you a roof that lasts forever, you won't keep buying more roofs. cars are similar.
[16:51:44] <CaptHindsight> aluminum panels with FEVE will last 100+ years
[16:52:14] <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.
[16:52:29] <CaptHindsight> I think that Rhino coatings are just ceramic with urethane
[16:52:54] <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.
[16:53:37] <CaptHindsight> furrywolf: we can have those, they just don't make them
[16:53:51] <furrywolf> if you try making a rust-proof car, you get framed for trafficing cocaine. :)
[16:54:44] <CaptHindsight> I'm actually working on a radcure FEVE coating that last 50+ years, and by last it just loses gloss vs needs recoat
[16:56:28] <CaptHindsight> from what I can see in the Rhono MSDS they are just urethanes with particles
[16:56:33] <CaptHindsight> ceramics
[16:56:52] <CaptHindsight> urethanes are good for 10-20 years
[16:58:30] <CaptHindsight> FEVE's were developed in the 80's, there is proof of it's durability for 30+ years in the field

[16:59:49] <CaptHindsight> FEVE with ceramic for roofing might last a lifetime
[17:00:30] <Rab> A lot of car mfgs are moving to aluminum body panels, actually, in an effort to keep weight down.
[17:01:02] <Rab> Anodized aluminum would be wicked, but also impossible to repair.
[17:01:12] * 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.
[17:01:13] <CaptHindsight> Land Rovers from the 50's still have bodies in great shape
[17:01:32] <furrywolf> CaptHindsight: that's because they're birmaloy or whatever made-up name for aluminum they used.
[17:01:58] <CaptHindsight> anodize also deosn't hold up well to alkalines
[17:02:14] <CaptHindsight> furrywolf: yes, they last too long :)
[17:02:50] <CaptHindsight> aluminum with a FEVE coating is easy to repair
[17:03:21] <CaptHindsight> aluminum + primer + color coat + clear
[17:03:42] <CaptHindsight> now the color might fade but it won't lose gloss
[17:03:56] <CaptHindsight> lead color last ages
[17:04:08] <CaptHindsight> but then there's the environmental concerns
[17:04:39] <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
[17:04:53] <CaptHindsight> ford in the 80's
[17:05:17] <CaptHindsight> anything metallic was the color of the primer in a few years

[17:49:50] <PetefromTn_> I need to get some nickel acetate, some degreaser/cleaner, and some etch solution going here so I can try this.

[17:51:19] <MrHindsight> have to go, but i can look for lower cost sources later

[18:20:29] <Jymmm> just the setbacks per parcel
[18:20:34] <zeeshan-laptop> when i manually touch a wire to ground from the other end of the solenoid which has a diode in parallel

[18:22:18] <zeeshan-laptop> the ground you put it on
[18:22:22] <zeeshan-laptop> itll sink over time
[18:22:26] <zeeshan-laptop> if its just soil

[18:23:08] <Jymmm> zeeshan-laptop: did you change anything in it? doors?
[18:23:13] <CaptHindsight> zeeshan-laptop: so a laser or similar that vaporizes a car on impact (the other guys car) would solve the problem

[18:25:04] <Jymmm> zeeshan-laptop: I have NFC
[18:25:33] <CaptHindsight> Jymmm: if you knew that was the possible consequence for being careless wouldn't that motivate drivers to change their habits?

[18:25:53] <Jymmm> CaptHindsight: Fuck no =)
[18:26:17] <CaptHindsight> Jymmm: well it would quickly reduce the number of them on the road
[18:27:55] <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.
[18:29:03] <zeeshan-laptop> fuck yes!
[18:29:04] <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.
[18:29:08] <zeeshan-laptop> all my DIO is working!!!!!!
[18:29:09] <zeeshan-laptop> !!!!!!!!!11
[18:29:16] <Rab> zeeshan-laptop, congrats!
[18:30:02] <CaptHindsight> the snakes keep the rats away
[18:30:41] <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.
[18:31:52] <Rab> I theorize that the ss slot flooring would be a good way to anchor machine tools (but maybe also lose your tooling).
[18:32:31] <zeeshan-laptop> ps mccdaq is a great company
[18:32:42] <zeeshan-laptop> really helpful people. you get directly to their engineers
[18:32:48] <zeeshan-laptop> not some noob

[19:21:31] <malcom2073_> Jymmm: You're talking about a metal shipping container?
[19:21:42] <Jymmm> malcom2073_: Yeah, but they have wooden floors
[19:21:56] <malcom2073_> It's the small holes that are the issue
[19:22:14] <Jymmm> malcom2073_: like rust holes, or ???
[19:22:42] <malcom2073_> No, shipping containers have a variety of holes and other latching points for picking them up, trying them down, locking the doors, etc
[19:22:49] <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

[19:24:38] <malcom2073_> You could probably surround it with sage heh

[19:33:27] <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
[19:33:53] <Jymmm> malcom2073_: but it was stil a 6 sided continaer?
[19:34:09] <malcom2073_> More like a bulging cylinder :-P
[19:34:17] <Jymmm> or 6 sided strainer
[19:34:29] <malcom2073_> I'll have to find my pictures of it

[19:34:43] <Jymmm> thats gotta say something

[19:35:07] <Jymmm> ah
[19:35:08] <malcom2073_> Nearby vehicles were toasted, and they were finding munitions spread about for weeks afterwards
[19:35:16] <Jymmm> ooooops
[19:35:22] <Jymmm> how did it start?
[19:37:12] <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.
[19:37:18] <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
[19:38:08] <malcom2073_> I imagine someone got in trouble for it though regardless heh
[19:39:31] <Jymmm> Hmmm, theres a lot more to having a container than I ever considered; https://www.youtube.com/watch?v=4QsnpK_erfU
[19:39:53] <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...
[19:40:17] <furrywolf> there exists photos of it, because everyone was just waiting for this to happen to they could point and laugh...
[19:40:21] <Jymmm> furrywolf: 45ft up a mountain n a 20ft truck https://www.youtube.com/watch?v=OOjO-omkPAk
[19:40:55] <malcom2073_> Jymmm: The logistics aren't simple... but they're not terrible. Do a *LOT* of research haha
[19:41:17] <furrywolf> what is there to having a container? you buy it, and... you have a container.
[19:41:20] <Jymmm> malcom2073_: and $1300 permit PER structure - bastards
[19:41:29] <malcom2073_> Damn! Your area sucks
[19:41:35] <malcom2073_> I like your idea of sticking wheels under it
[19:41:36] <malcom2073_> :-D
[19:41:50] <malcom2073_> Don't even have to work
[19:41:52] <malcom2073_> just bolt wheels to it
[19:41:57] <Jymmm> malcom2073_: exactly
[19:42:00] <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
[19:42:10] <malcom2073_> haha
[19:42:24] <Jymmm> furrywolf: oh, heh
[19:43:17] <Jymmm> I love how they get the container off the trailer.... just rip it off with a tractor =)
[19:43:26] <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...
[19:44:13] <Jymmm> furrywolf: sounds reasonable to me. but then again not my truck =)
[19:44:13] <furrywolf> got to the first turn, trailer and back of truck just kept going straight, which everyone but him predicted...
[19:44:35] <furrywolf> then everything went sideways.
[19:44:39] <Jymmm> lmao
[19:44:45] <furrywolf> across both lanes of the freeway.
[19:44:51] <Jymmm> Nice
[19:45:08] <furrywolf> took them several tow trucks to get it back rightside up, freeway blocked for like an hour...

[19:46:06] <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.
[19:46:08] <furrywolf> they're not considered a structure
[19:46:19] <Jymmm> furrywolf: county?
[19:46:36] <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.
[19:46:39] <Jymmm> furrywolf: which county are you in?
[19:46:41] <furrywolf> humboldt, california
[19:47:06] <Jymmm> furrywolf: Hmmm, no idea
[19:48:32] <furrywolf> where the heck are you that requires a permit for movable property?
[19:48:38] <Jymmm> furrywolf: 14KB permit required http://www.hcnv.us/bldg_dpt/documents/Storagecontainer12-13_000.pdf
[19:48:44] <furrywolf> there's proper legal terms for fixed/movable that I can't remember right now.
[19:49:11] <Jymmm> furrywolf: if you find them please let me know.
[19:49:27] <Jymmm> furrywolf: $1300 for a permit is excessive
[19:49:40] <furrywolf> lol, you're in humboldt, nv, while I'm in humboldt, ca?
[19:49:42] <Jymmm> furrywolf: no rush or anything
[19:49:57] <Jymmm> oh, did I get the wrong state?
[19:51:16] <furrywolf> yes :P
[19:52:04] <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.
[19:52:46] <furrywolf> also, that sounds like it's aimed for permanently installed containers being used as buildings. you just need to claim it's movable.
[19:52:47] <Jymmm> furrywolf: Yep, PLUS re-engineering too... ventilation, man door (fire escape)
[19:53:13] <Jymmm> furrywolf: Yeah, thus the need for the legal definition
[19:53:50] <Jymmm> furrywolf: I still say head down to harborfreight and get four $3 tires and install them on the container
[19:53:51] * SpeedEvil wonders what the difference between a man-door and a woman-door would be.
[19:54:15] <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
[19:54:39] <Jymmm> SpeedEvil: purple?
[19:55:01] <Jymmm> SpeedEvil: sorry, I meant lavenender
[19:55:44] <furrywolf> I've been tempted to build a workshop on a trailer frame... so I can tow it with me when I move.
[19:55:55] <furrywolf> shipping containers are a bit small, and around here, EXPENSIVE.
[19:56:01] <furrywolf> a beat up 20ft is $2500.
[19:56:53] <furrywolf> you see gutted RVs pretty regularly... just build a 10ft wide shop on the frame from one.
[19:56:59] <furrywolf> s/RV/house trailer
[19:57:53] <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.
[19:57:58] <SpeedEvil> furrywolf: In general >8.5ft requires permits from damn near everywhere to tow
[19:58:39] <furrywolf> SpeedEvil: in general no one stops you until you get over 10ft... :P
[19:58:52] <furrywolf> I think around here 10ft needs a pilot car but not a permit, but I'm not sure.

[20:13:05] <furrywolf> they could declare a shipping container to be a plains zebra and subject to a zookeeper's permit...
[20:13:24] <Jymmm> =)
[20:13:54] <Jymmm> furrywolf: But If I install lawnmower wheels on it, and get it defined as an off road trailer =)
[20:14:10] <Jymmm> furrywolf: then it's under chp/dmv =)
[20:14:37] <furrywolf> around here, mobile homes are like that... you have to keep the registration sticker current, however.
[20:14:58] <Jymmm> furrywolf: not for off road trailers as I understnd it
[20:15:20] <Jymmm> furrywolf: like a farmer pulls a trailer behinf a tractor
[20:15:37] <Jymmm> CHP is out to lunch so no answer
[20:15:41] <furrywolf> lol
[20:16:05] <furrywolf> what is the ordinance that requires you to have a permit?
[20:16:52] <Jymmm> nothing says the lawnmower wheels actually have to work =)

[20:18:47] <zeeshan-laptop> we talked about this yesterday
[20:18:48] <Jymmm> much much is it to have eaves repaird?
[20:18:50] <zeeshan-laptop> im physically doing it now
[20:18:52] <furrywolf> so don't say you're using it as a storage building.
[20:19:12] <furrywolf> you're using it for shipping, and lading cargo.

[20:32:39] <zeeshan-laptop> i just placed an order
[20:32:47] <zeeshan-laptop> hopefully that is all it needs

[20:33:05] <zeeshan-laptop> wish it just output 0-5v
[20:33:06] <zeeshan-laptop> not 4-20
[20:33:16] <zeeshan-laptop> but iguess 4-20 mA lets you scale it to whatever

[20:34:52] <furrywolf> Is it expensive to repair a car?
[20:35:00] <zeeshan-laptop> im just gonna resistor it up
[20:35:07] <Jymmm> or cheaper in the long run to replace the roof and have them replaced then?
[20:36:01] <furrywolf> ...
[20:36:20] <furrywolf> much like a car, roof eaves can have a wide variety of problems of varying severity.
[20:36:42] <XXCoder> eaves new word
[20:37:16] <XXCoder> interesting
[20:37:19] <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
[20:37:25] <zeeshan-laptop> fuck
[20:37:34] <zeeshan-laptop> i just realized the signal conditioning unit i got is the wrong one
[20:37:37] <XXCoder> it let out magic smoke?
[20:37:46] <zeeshan-laptop> it takes 0 to 5v input and outputs 0to 20mA
[20:37:50] <zeeshan-laptop> shoud be 4 to 20mA :(
[20:38:10] <zeeshan-laptop> losing resolution ;/
[20:38:13] <furrywolf> so get the right one. lol

[20:38:23] <zeeshan-laptop> theyre gonna be pissed
[20:38:24] <furrywolf> losing resolution?
[20:38:45] <zeeshan-laptop> yes cause say i set 1V
[20:38:49] <zeeshan-laptop> and it outputs 2mA
[20:38:58] <zeeshan-laptop> the controller won't recognize the signal
[20:39:04] <furrywolf> ah.
[20:39:15] <zeeshan-laptop> maybe ill just make it work ;/
[20:39:22] <furrywolf> so your input device doesn't read below 4ma, and can't be configured to do so?
[20:39:31] <jdh> most have zero and span adjustments
[20:39:40] <furrywolf> bias the 0-5V.
[20:40:25] <furrywolf> use a voltage divider to scale the 0-5V to 0-4V, then an opamp to add 1V to it. :P

[20:43:05] <furrywolf> you don't lose resolution... you lose the ability to read a portion of the values.
[20:43:15] <furrywolf> which will be recognized as a failure instead
[20:46:29] <zeeshan-laptop> ill just limit my voltage output
[20:46:34] <zeeshan-laptop> to go between a certain voltage..
[20:46:40] <zeeshan-laptop> so it correctly outputs 4-20mA
[20:47:06] <zeeshan-laptop> so ill always output for example 1-5V only
[20:47:17] <zeeshan-laptop> and 1V means 100 celsius
[20:47:25] <zeeshan-laptop> 5V means 500celsius

[21:01:03] -!- per_sonne has quit [Ping timeout: 248 seconds]
[21:01:22] <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.
[21:02:14] <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.
[21:03:12] <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
[21:03:45] <kyle__> monttyle: But the delta 3d printers can exactly map to carteasian printers. Polar printers can't exactly map.
[21:03:49] <kyle__> monttyle: From a math standpoint.
[21:04:14] <kyle__> So nobody does CNC conversions to wood lathes?
[21:04:30] <kyle__> They're really that different of a tool than metal ones?
[21:04:32] <monttyle> kyle__: There's not a whole lot there to convert.
[21:04:38] <monttyle> The tool holder is missing.
[21:05:21] <JT-Shop> kyle__, sure hundreds convert wood lathes to CNC but not anyone watching this second
[21:05:43] <kyle__> yeah... I did notice that. I ordered a threadded rod to build up some sort of carriage for a tool.
[21:06:51] <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.
[21:07:37] <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.
[21:09:22] <kyle__> monttyle: The tuning procedure to get the scaling right on them isn't confidence inspring, I'll admit that.
[21:09:27] <zeeshan-laptop> test
[21:10:28] <JT-Shop> failed
[21:10:43] <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'.

[21:12:04] <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.
[21:12:22] <kyle__> But yeah, lots of people are going the lazy route there.
[21:12:26] <monttyle> There's printers which can't be levelled any other way, and people who'll defend it to the death.
[21:13:18] <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.

[21:14:12] <XXCoder> monttyle: thats interesting setup
[21:14:54] <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
[21:15:05] <XXCoder> monttyle: from what I see, it has a circle workspace. certainly odd
[21:15:09] <XXCoder> actually no
[21:15:22] <XXCoder> trangle
[21:15:28] <kyle__> XXCoder: trapazoidal I thought glancing at it.
[21:15:55] <XXCoder> nah trangle. at closest to rod it would be unable to move (assuming its fully extended and rod size is same)
[21:16:06] <XXCoder> trapazoidal more general word yeayh

[21:22:00] <XXCoder> yeah
[21:22:02] <monttyle> I hoped it would be a lot more rigid for something small, than trying to make a parallel arrangement.
[21:22:38] <XXCoder> even more rigid would have that arrangements on both sides I bet thats possible
[21:22:53] <XXCoder> workspace would be square but 45 degrees rotated
[21:23:26] <XXCoder> but man very complex controls
[21:23:29] <monttyle> Hm, maybe. The shaft could just be done with a belt, but you couldn't do that with the captive motor.
[21:24:04] <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.
[21:24:25] <XXCoder> makes sense. double side other side would do opposite
[21:25:01] <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.
