[00:28:10] <TekniQue> Question about G code and linuxcnc
[00:28:12] <Crom> I lived there a time or 3
[00:28:27] <Crom> TekniQue, ask away
[00:28:29] <TekniQue> I was milling something today, haven't used my mill in quite a couple years
[00:28:51] <TekniQue> cutting profiles in a piece of plastic, used cambam to generate the G-code
[00:29:15] <TekniQue> problem is, I started out with too much speed and notices that the controller was taking shortcuts around corners
[00:29:39] <TekniQue> so instead of coming to a full stop at corners it'd skip the corner to save on deceleration
[00:30:01] <Crom> That's G64,
[00:30:23] <Crom> google G64 G61 G61.1
[00:30:40] <Crom> Constant speed vs. exact cut
[00:30:53] <TekniQue> thanks
[00:31:38] <Crom> there is a setting for how far away from the actual line you'll allow the mill to get
[00:32:20] <furrywolf> I thought the default was "close enough you won't notice"
[00:33:26] <Crom> that's the second G61,G64 in 2 weeks
[00:33:52] <zeeshan> http://i.imgur.com/Xf6Hj2F.png
[00:34:00] <zeeshan> those fan blades were fun to make
[00:34:19] <TekniQue> mhm
[00:34:26] <TekniQue> I found the setting in Cambam
[00:35:53] <Crom> I haven't used CamBam
[00:36:03] <TekniQue> It's pretty basic
[00:36:35] <TekniQue> can import DXF
[00:36:36] <Tom_itx> zeeshan make it a round chamber
[00:36:46] <Crom> I tend to do all my stuff G61 since I'm cutting gears or slots
[00:36:49] <TekniQue> and then you select elements of the DXF and convert them to machining operations
[00:36:49] <zeeshan> Tom_itx: no
[00:37:04] <Crom> zeeshan, no no Ovoid!
[00:37:13] <zeeshan> Tom_itx: harder to form and mount lol
[00:37:22] <zeeshan> but better circulation!
[00:37:53] <Crom> ok I'm off to the creator space... trying to get the RepRap going
[00:38:10] <Crom> board it came with I can't get to talk to the computer
[00:38:33] <Crom> so I'm swapping it out for a Geeetech Melzi
[00:40:07] <zeeshan> i think im gonna have to use a remote shaft
[00:40:23] <zeeshan> a shaft to place the fan blade inside the chamber, while the motor is outside
[00:40:27] <zeeshan> so it doesnt blow up the motor
[00:40:32] <zeeshan> i cant find a motor that can take 300C :P
[00:43:57] <zeeshan> Tom_itx: i like your round idea.

[01:48:14] <zeeshan> the polymers grew on me
[01:48:20] <zeeshan> i wasn't a big fan of them either...
[01:48:25] <zeeshan> i really like structural and forming
[01:48:39] <CaptHindsight> there is just so much you can do with it
[01:49:13] <CaptHindsight> so much that hasn't even been touched yet
[01:49:34] <CaptHindsight> I need to brush up on my biology
[01:51:46] <CaptHindsight> i stated working on water soluble polymers recently (post cure) now I'm looking at grafting water soluble proteins onto monomers which is a really new field
[01:52:42] <CaptHindsight> or proteins from animal cell walls onto monomers and oligomers to make nanomachines that the immune system won't attack

[01:56:30] <CaptHindsight> shape memory polymers are neat since they combine polymers with mechanics

[02:01:43] <zeeshan> all this round stuff
[02:02:14] <furrywolf> that looks overcomplicated.
[02:02:24] <zeeshan> make it better
[02:02:28] <zeeshan> and easier to fab
[02:02:34] <zeeshan> all this stuff, i can easily make

[02:04:33] <furrywolf> how big is your sample?
[02:04:37] <furrywolf> (the thing being tested)
[02:04:54] <zeeshan> 2" diameter
[02:05:02] <zeeshan> i might move to 3"
[02:05:02] <zeeshan> max
[02:05:10] <furrywolf> and how big is that thing you designed to put it in? lol
[02:05:17] <zeeshan> about 12"
[02:05:18] <zeeshan> :D
[02:05:24] <zeeshan> with 2" of insulation layer
[02:05:40] <zeeshan> i will optimize later, i just need a bare bones to start heat transfer simulation on
[02:05:56] <furrywolf> are you trying to heat/cool the sample by conduction (directly sitting on something), or only by changing the ambient air around it?
[02:06:04] <zeeshan> furrywolf: both
[02:06:38] <zeeshan> so forced convection and conduction
[02:06:41] <furrywolf> how does it to do both when the middle looks hollow?
[02:07:14] <zeeshan> there are a lot of middles
[02:07:17] <zeeshan> which middle haha
[02:07:38] <zeeshan> are you talking about the big gaping hole in the top lid?
[02:07:53] <furrywolf> can you skip convection and use radiation heating, with an IR thermometer to measure surface temp and adjust ir source appropriately?
[02:08:05] <zeeshan> doesnt cool
[02:08:52] <furrywolf> correct, but if the air around it is cold, and you turn the heat off...
[02:09:33] <zeeshan> those heating elements in there are like 25$ each
[02:09:36] <zeeshan> and theres two
[02:09:39] <zeeshan> 750W
[02:09:45] <zeeshan> or 500W (i forget)
[02:10:56] * furrywolf adds wheels to it and christens it lunokhod
[02:10:58] <zeeshan> i wonder how quickly you can blow up an ir bulb
[02:11:08] <zeeshan> a heating bulb by cycling it
[02:12:19] <furrywolf> given as printer fusers last gazillions of cycles, I'd say you have to work at it.
[02:13:28] <zeeshan> which hole were you talkin about??
[02:13:57] <furrywolf> the greenest area in the center
[02:14:16] <zeeshan> thats where the film goes
[02:14:19] <zeeshan> and air blows from the bnottom side
[02:14:35] <zeeshan> the top of the film thats exposed in the chamber is what im trying to convectively cool/heat
[02:14:36] -!- archivist_herron has quit [Ping timeout: 252 seconds]
[02:14:57] <zeeshan> and the bottom of the film is what im trying to cool / heat through conduction->then convection of the air
[02:15:04] <zeeshan> thats trapped ballooning the film
[02:15:34] <furrywolf> so there is no actual conduction to the film, then?
[02:16:02] <zeeshan> very little if any
[02:16:10] <zeeshan> because its a really good insulator
[02:16:21] <zeeshan> like to give you a feel for it
[02:16:33] <zeeshan> i had the film at 260C and i opened the oven door and i grabbed it with bare hands
[02:16:36] <zeeshan> within 10 seconds..
[02:17:07] <furrywolf> so there's compressed air on bottom, outside air pressure on top?
[02:17:20] <zeeshan> yea ambient on the top
[02:17:37] <zeeshan> im gonna have a small gap to ensure it never pressurizes
[02:17:41] <zeeshan> (the ambient side)

[02:18:13] <furrywolf> yes, you'll need a decent amount of venting, or it'll pop when heating or implode when cooling.

[02:20:45] <zeeshan> that looks scary to stand next to
[02:20:47] <zeeshan> but so bad ass!
[02:21:46] <furrywolf> so in addition to the heating elements, you have fluid loops somewhere in there?
[02:21:58] <zeeshan> yes
[02:22:06] <zeeshan> http://i.imgur.com/N1whRmt.png
[02:22:10] <zeeshan> you can see the fluid loop thingy there
[02:22:21] <furrywolf> I can't load images until the youtube video loads or I cancel it.
[02:22:28] <zeeshan> watch the video!
[02:22:29] <zeeshan> its cool

[04:24:28] <zeeshan> hmm
[04:34:58] <Crom> just thinking wouldn't a squirrel cage fan drawing off the hit sink and blowing towards the side work better?

[16:39:55] <malcom2073> buddy of mine got one of those, they're really awesome once you hack them
[16:39:59] <Rab> zeeshan, you should buy a Seek: http://www.thermal.com/
[16:40:11] <zeeshan> rab is it of thje same resolution
[16:40:12] <zeeshan> and 60hz?
[16:40:28] <zeeshan> and -20 to 650C range?
[16:40:47] <Rab> zeeshan, is cost a criterion?
[16:40:53] <zeeshan> 4500
[16:40:57] <zeeshan> its not for me
[16:41:07] <zeeshan> i was talking to timecop thru pm
[16:41:10] <zeeshan> he seems to recommend the e40
[16:41:23] <zeeshan> i just wish i could try it out before comitting it
[16:41:30] <zeeshan> i dont want people yelling at me for makin a bad choice :P
[16:41:34] <malcom2073> zeeshan: You can turn an E4 into an E40 :P
[16:41:40] <zeeshan> malcom2073: you cant
[16:41:43] <malcom2073> erm, rather an e8
[16:41:53] <zeeshan> the refresh rate is very different
[16:41:59] <zeeshan> and the temp range is very diff too
[16:42:00] <Rab> Seek resolution is actually better, although framerate and temp range are worse.
[16:42:27] <zeeshan> rab timecop was sayin yo ucould get a lens for it
[16:42:38] <zeeshan> if the standarded resolution isn't good enough
[16:42:49] <Rab> zeeshan, how does a lens increase resolution?
[16:42:58] <zeeshan> it doesnt lol
[16:43:23] <zeeshan> im thinking aboujt something else and answering something else
[16:43:31] <zeeshan> my issue is, if im 1 foot away from the object of interest
[16:43:38] <zeeshan> i wanna be able to have a non blurry image..
[16:43:54] <zeeshan> apparently with the 45 degree lens, you can resolve .2mm areas
[16:44:14] <zeeshan> 7 thou!
[16:44:16] <Rab> If timecop uses it, it's probably not a total piece of crap. I'm just saying there'd be a good alternative for $250 if it was your money.
[16:44:30] <zeeshan> yes its not for me
[16:44:32] <zeeshan> they want something for the lab
[16:44:38] <zeeshan> without spending 10k
[16:44:44] <zeeshan> 4500 is affordable for them
[16:44:57] <zeeshan> we wanna be able to capture thermal gradients for say a tensile test
[16:45:03] <zeeshan> or verify uniform temperature
[16:45:04] <Rab> Probably fine then. The Seek needs a phone anyway.
[16:45:12] <zeeshan> and do it fast enough
[16:45:50] <zeeshan> http://www.innventia.com/PageFiles/5596/2012-27-02-p329-334-Hyll.pdf?epslanguage=sv
[16:46:02] <zeeshan> if you go to physical page 332
[16:46:27] <zeeshan> look at figure 6. it's kinda cool how you can see the temperature rise at failure
[16:47:26] <zeeshan> some guy was presenting a study yesterday where he was showing that strain localizing due to dislocation pile up leads to a localized temperature rise which can be correlated to the location where fracture will happen
[16:48:01] <zeeshan> but if you kept strain constant and allowed the stress to relax a bit, you can actually see that thermal gradient dissipate
[16:48:21] <zeeshan> and now you can prolong fracture
[16:48:30] <zeeshan> even when you increase the strain

[17:15:58] <archivist> for the ultimate use of that effect see rubber tire making
[17:18:32] <FinboySlick> zeeshan: I was wondering earlier... That part with two heating element you pasted yesterday. Why not stick it on an induction heater plate? That way you'd only have to engineer the cooling aspects.
[17:19:39] <renesis> haha @ FLIR at a coffee cup
[17:20:07] <renesis> we did pretty well proving those were useless for absolute temps unless you were looking at big flat black panels
[17:20:26] <renesis> theyre excellent for figuring out where to put the thermocouples
[17:20:47] <renesis> i think we could have spent the money better
[17:20:47] <archivist> I suppose you can have a measured spot to calibrate an image
[17:21:08] <renesis> right but if your image is of different materials that doesnt help

[17:28:29] <zeeshan> most of the times you're measuring stuff from the same material
[17:28:38] <zeeshan> and its not hard to compensate for emissivity after you've captured the data.
[17:29:10] <zeeshan> FinboySlick: i was thinking the 2 elements would be easier to implement
[17:29:23] <zeeshan> cause i could bury them deep into the heating block
[17:29:40] <zeeshan> and keep it all compact
[17:31:03] <zeeshan> renesis: thermocouples are inferior in the sense they can't capture a gradient.
[17:31:12] <FinboySlick> zeeshan: Yeah, my suggestion was on the assumption that the block is standalone. I didn't catch if it was a part of a larger machine.
[17:31:59] <renesis> use lots, gradients dont matter for what were usually doing so would be hard to call it inferior when the results are more accurate
[17:32:11] <renesis> but yeah for your thing it probably works
[17:32:15] <zeeshan> thermocouples have their own issues
[17:32:20] <renesis> FLIR at coffee cup is the equiv of FLIR at people nuts
[17:32:29] <zeeshan> they heat the thing you're trying to measure
[17:32:33] <renesis> which is what usually happens when a place i work gets one
[17:32:55] <renesis> heat the thing youre trying to measure?
[17:33:20] <zeeshan> yes
[17:33:33] <renesis> were measuring small parts that get to 100C with twisted extension wire
[17:33:59] <zeeshan> the main issue i see with ir cams is emissivity
[17:34:00] <renesis> the voltage potential isnt even mV, theres like no current
[17:34:16] <zeeshan> if you could overlay an emissivity point cloud on top of the thermal data
[17:34:19] <renesis> right which is an issue when you cant paint everything black
[17:34:19] <zeeshan> you could compensate probably
[17:34:27] <renesis> or when you have a hundred diff materials on a PCBA
[17:34:47] <renesis> and were trying to have the data presented in like, an hour
[17:35:13] <renesis> also FLIR does no work on a closed system
[17:35:27] <zeeshan> what do you mean closed system
[17:35:38] <renesis> like, enclosed
[17:35:47] <zeeshan> thats why they have ir windows
[17:35:56] <renesis> window would change things

[18:12:51] <zeeshan> http://www.omega.ca/pptst_eng/SV3100.html
[18:12:54] <zeeshan> a solenoid like this
[18:13:09] <zeeshan> using dc it has an opening time of 20 to 80 msec
[18:13:32] <zeeshan> my question is, can you pulse this things on and off
[18:13:35] <zeeshan> without blowing them up
[18:14:04] <zeeshan> pcw_home: your expertise would be nice!
[18:14:08] <zeeshan> pid master.
[18:16:57] <archivist> solenoids like that should have an operating time and a operation count lifetime
[18:18:23] <archivist> ask the to define Cycling Rate: Approx. 1000 cpm and lifetime at that rate
[18:18:28] <archivist> them
[18:18:49] <archivist> is the m minute or month
[18:18:55] <zeeshan> minute
[18:18:56] <zeeshan> lol
[18:19:57] <zeeshan> its kinda hard to find a solenoid valve that can handle 260C..
[18:20:00] <archivist> 1000 per minute is rather a lot
[18:20:22] <archivist> better to use a valve and servo
[18:21:22] <zeeshan> too expensive :(
[18:21:31] <zeeshan> i need two of these things

[18:45:37] <zeeshan> archivist: youre right it will be slower
[18:45:48] <zeeshan> im cycling pressure
[18:45:49] <zeeshan> not temperature
[18:46:03] <zeeshan> if i set it to 10 psi, i want it to be hold 10 psi, regardless of temperature rise
[18:47:11] <archivist> just use normal pressure regulators
[18:47:28] <zeeshan> omega told me this
[18:47:30] <zeeshan> All the ordinary pneumatic pressure regulators http://www.omega.ca/pptst_eng/PRG101.html assume a lower pressure on the Output pressure than the supply pressure. The situation where the air is heated and the air pressure on the output increase by itself (by heating ) is unusual.
[18:47:44] <zeeshan> There are pressure relief valves for excessive pressure,
[18:47:54] <zeeshan> but it is easy to imagine an oscillation between the pressure input regulator and the pressure relief valve. I can only imagine that you would need to have the input and output valves under the control of a single custom software . Omega can supply only the solenoids
[18:48:38] <zeeshan> see the dilemma? :)
[18:49:18] <archivist> you could adjust the volume with temperature
[18:49:58] <archivist> you could use a pressure balance with a weight
[18:50:07] <archivist> easier
[18:50:45] <zeeshan> hm
[18:51:01] <zeeshan> would eliminate the need for pid
[18:51:02] <zeeshan> :P
[18:51:02] * ffurrywol seems to remember a long time ago saying to use linuxcnc for this. :P
[18:52:12] <ffurrywol> I built what you're doing a while ago, and it worked great, even though I only had a simple deadband-based control.
[18:52:13] <archivist> I got some strange books :) ttp://www.collection.archivist.info/searchv13.php?searchstr=pressure+balance
[18:52:39] <ffurrywol> http://fw.bushytails.net/brakeplumbing01.jpg
[18:53:28] <archivist> what no adjustable spanners in that pic!
[18:53:33] <zeeshan> http://i.imgur.com/CaleMXq.png
[18:53:41] <zeeshan> so basically i'd have that T
[18:53:48] <zeeshan> and one side of the T would go to an expansion chamber?
[18:53:53] <zeeshan> and the other side would be inlet
[18:53:54] <ffurrywol> archivist: look under and to the left of the utility knife
[18:54:11] <archivist> yup
[18:54:40] <zeeshan> the expansion/contraction cahmber would be a controlled using some sort of motor?
[18:54:47] <archivist> my arse pocket always has one
[18:55:10] <archivist> weight on a piston
[18:55:21] <ffurrywol> two valves should work fine
[18:55:22] <zeeshan> i don't get it
[18:55:24] <zeeshan> how is the weight movin
[18:55:34] <ffurrywol> I got a lot better control than I expected
[18:55:48] <zeeshan> ffurrywol: the problem with valves right now im facing is
[18:55:55] <zeeshan> finding ones that can handl 260-300C
[18:56:03] ffurrywol is now known as furrywolf
[18:56:24] <zeeshan> using a coil for actuation..
[18:56:33] <furrywolf> your valves don't need to handle high temperatures. just put a loop of copper tubing somewhere between the chamber and your valves.
[18:56:52] <zeeshan> yes, but th e further i place them
[18:56:58] <zeeshan> the larger the volume of air
[18:57:05] <zeeshan> the harder to control? :)
[18:57:13] <furrywolf> the further you place them, the more air capacity you have, and the less often you need to cycle them to maintain a precise pressure.
[18:57:29] * zeeshan nods
[18:58:22] <archivist> been trying to knock that more volume sense into our boiler firemen this last weekend
[18:59:18] <zeeshan> it makes sense
[18:59:25] <furrywolf> the assembly I built in that picture would do what you need just fine, and didn't involve any exotic components. :P
[18:59:25] <zeeshan> youre increasing the thermal capacity of the air
[18:59:55] -!- per_sonne has quit [Quit: Be back later ...]
[19:00:00] <archivist> percentage change of volume becomes smaller
[19:00:15] <archivist> same difference sort of

[19:00:40] <zeeshan> i wont even need a control system..

[19:01:13] <zeeshan> i like what i see

[19:01:54] <furrywolf> it's a magic box that lets you hook trailers with air brakes up to vehicles with electric trailer brake controllers. :)

[19:11:27] <zeeshan> i wouldnt get hardcore like you with the electronics though
[19:11:37] <zeeshan> id prolly just use a rp 2
[19:11:44] <zeeshan> for both daq and pid control
[19:12:11] <zeeshan> i wonder if i could just use a standard temp pid control and make it work with pressure
[19:12:16] <zeeshan> they should have some deadband settings..
[19:12:38] <furrywolf> you'd need a heat and cool temp pid, which as you found was expensive.
[19:12:57] <furrywolf> I don't know if a single quad opamp chip counts as hardcore. :)

[21:02:17] <zeeshan> nah
[21:02:20] <furrywolf> a 1-way valve would be... a plug?
[21:02:27] <renesis> yeah id youre talking about valves no idea

I used to have a large tank connected to my little air compressor, but it took way too long to fill. want to put in a check valve, pressure switch, and solenoid valve, that lets the big tank fill only when the little tank is full, so I have full pressure available quickly...
[21:10:28] <zeeshan> if i need to save money, ill use the link you gave me
[21:10:33] <zeeshan> im sure theyre the same thing.
[21:11:07] <furrywolf> they're definitely different valves

[21:12:49] <zeeshan> i mean similar performance
[21:13:20] <furrywolf> hrmm, to put two valves in parallel, I'll need to use either hoses or unions... probably hoses or copper line is cheaper and less requiring of perfect lengths.
[21:18:58] <furrywolf> this seems like something I should be able to build mechanically.
[21:19:12] <furrywolf> rather than needing a check valve, a pressure switch, a solenoid valve, and a power source.
[21:19:46] <furrywolf> like by removing the electrical contacts from a pump switch and putting a push-button air valve in their place.

[21:30:54] * furrywolf is surprised this isn't an off-the-shelf product
[21:32:55] <SpeedEvil> A simple pressure switch that turns on at just below the normal switch off pressure, and opens a small valve adequate to keep up with but no more than the compressors max output would work I guess
[21:33:28] <SpeedEvil> No need for a backflow diode
[21:33:32] <SpeedEvil> valve
[21:34:10] <Jymmm> lol
[21:34:25] <furrywolf> the check valve would be anti-parallel, to let air flow from the large tank into the small tank, which has the loads connected to it.

[21:48:38] <zeeshan> on.
[21:49:14] <furrywolf> as in, wait until the compressor shuts off, then join the tanks?
[21:49:24] <zeeshan> yes
[21:49:57] <zeeshan> asap the compressor goes off, the air will start transferring over

[21:50:25] <SpeedEvil> furrywolf: seems a printed or DIY valve would work fine
[21:50:26] <zeeshan> but its simple!
[21:50:32] <SpeedEvil> ~100PSI isn't that hard to manage
[21:50:52] <furrywolf> .. if I build a valve, it'll be done on my milling machine. no printing.
[21:50:57] <SpeedEvil> yeah
[21:51:14] <zeeshan> plastic valve KABOOM
[21:51:19] <furrywolf> however, I think that graco sprayer pressure regulator will accomplish the task.
[21:51:45] <furrywolf> it's a shunt regulator... when the inlet pressure exceeds the setpoint, it lets it flow to the output.
[21:52:27] <SpeedEvil> zeeshan: sometimes kaboom is just fine
[21:52:48] <SpeedEvil> zeeshan: if the worst that a failure can do is make your thing not work
[21:52:59] <furrywolf> just set it to 10psi below the compressor cutoff, and when the little tank hits that, it starts letting it flow into the big tank.
[21:53:28] <furrywolf> there are no "just fine" kabooms when compressed air is involved. compressed air makes things turn into high-speed shrapnel.

[21:55:45] <SpeedEvil> yes - but it's all about enclosed volume.
[21:55:49] <SpeedEvil> The tank is dangerous.
[21:55:56] <SpeedEvil> A valve - pretty much - is not
[21:56:11] <furrywolf> right. what's the enclosed volume of a bb gun, and what's it do to your eye?
[21:56:12] <SpeedEvil> (unlesss of course it failing can overpressurise a tank
[21:56:23] <SpeedEvil> and yes - of course you'd want to cover it
[21:57:17] <furrywolf> 3d printing sounds like an absolutely horrible technique for valve construction.
[21:58:19] <furrywolf> explosion risk, porus walls if feed not perfect, crap tolerance, rough surfaces for contaminants to adhere to, rough surface that won't seal for the valve seat, soft plastics unable to hold threads, low temperature limit (air comes out of an air compressor quite warm), and expensive. perfect!
[22:00:24] * furrywolf could also just put in a quarter-turn ball valve, and have it be manumatic.
[22:00:30] <zeeshan> WELL I
[22:00:31] <zeeshan> er
[22:00:35] <zeeshan> well i can see SpeedEvil's point
[22:00:42] <zeeshan> theres tons of air pressure stuff thats plastic
[22:00:46] <zeeshan> and easily takes 100psi

[22:01:29] <zeeshan> 100psi
[22:01:35] <furrywolf> can you print pure nylon?
[22:01:39] <SpeedEvil> Work out the hoop stress for a .2" valve. It's not very much.
[22:01:48] <zeeshan> furrywolf: hell YA
[22:01:50] <furrywolf> I had some pure teflon valves. sold them on ebay for $$$.
[22:02:16] <furrywolf> SpeedEvil: pressure-sensitive valves have large diaphragms, generally with a couple square inches of surface area.
[22:02:29] <furrywolf> you need the control force to far exceed the forces applied to the valve
[22:02:34] <SpeedEvil> If you want them to be very sensitive, yes.
[22:02:39] <zeeshan> pr/t = 100*.1/.1

[22:05:14] <zeeshan> and outlet on the other.
[22:05:35] <furrywolf> your pressure transducer will get too hot. put it by the valves.
[22:05:41] <zeeshan> im purposely am keeping the transducer closer to the

[22:05:54] <furrywolf> yes, I know why you're doing it. it's still not going to work. :)
[22:06:04] <zeeshan> whats not gonna work

[22:11:59] <furrywolf> a second copper coil.
[22:12:01] <SpeedEvil> zeeshan: unless there is significant flow in the tube, there is no pressure drop
[22:12:24] <SpeedEvil> zeeshan: or is this a combustion engine with very fast varying pressures where it may matter
[22:13:02] <furrywolf> SpeedEvil: it's a strain-applying test rig for his shape memory polymers. pressure changes are on the rate of a minute or more for a few psi... :P
[22:13:07] <zeeshan> im thinking there will be a small pressure lag
[22:13:29] <furrywolf> pressure changes travel through the tube at the speed of sound.
[22:13:29] <SpeedEvil> zeeshan: It's basically several times the speed of sound delay in the pipe
[22:13:49] <furrywolf> with no flow, that is.

[22:22:31] <furrywolf> sure you don't want slow speed, to prevent vibration, ripples, etc from screwing with your polymer?
[22:22:43] <zeeshan> might not be enough cfm?
[22:23:59] <furrywolf> you don't need much cfm. lol
[22:24:07] <zeeshan> turbulence!
[22:24:17] <furrywolf> you're trying to heat/cool a small volume of air and a thin polymer with almost no thermal mass
[22:24:37] <furrywolf> turbulence creates localized pressure and vacuum on your polymer, and is bad. :P
[22:25:01] <furrywolf> you don't want your polymer fluttering.
[22:26:07] <zeeshan> meh :/
[22:26:12] <zeeshan> its better to have more fan than less!
[22:26:18] <zeeshan> so i can always slow it down or something
[22:26:20] <zeeshan> http://www.omega.ca/pptst_eng/PX309-5V.html
[22:26:25] <zeeshan> 0 to 5V output.
[22:26:38] <zeeshan> hmm
[22:28:59] <zeeshan> too bad the raspberry pi 2 doesnt have an internal adc.
[22:29:26] <SpeedEvil> Or sanity.
[22:29:38] <zeeshan> im so used to using it though now
[22:29:47] <zeeshan> itll be a pain to switch to beagle bone
[22:29:47] <furrywolf> you're not getting .1% accuracy out of any component on an rpi.
[22:29:50] <SpeedEvil> (for example, GE MAC on-board, or more than one USB port that everythings connected to.
[22:30:01] <zeeshan> furrywolf: what does raspberry pi have to do with anything?
[22:30:01] <SpeedEvil> furrywolf: time is quite easily to within .1%
[22:30:11] <zeeshan> w/ accuracy
[22:30:27] <zeeshan> it depends on the adc the sensor is connected to
[22:30:29] <zeeshan> ..
[22:30:30] <zeeshan> :P
[22:30:38] <furrywolf> because it's built using low-cost on-chip components, which don't tend to have precision instrument amps, etc?
[22:30:48] <zeeshan> you use an external precision amp
[22:30:58] <zeeshan> and send the data over serial
[22:31:10] <furrywolf> how about using a cheapo chinese multimeter with rs232 output? :P
[22:31:22] <zeeshan> if i didnt have to log vs time
[22:31:26] <zeeshan> i would do that
[22:31:33] <furrywolf> what's your time scale?
[22:31:47] <zeeshan> .1 s would be good neough
[22:32:04] <furrywolf> http://www.amazon.com/TekPower-TP4000ZC-RS232-Interfaced-Ranging-Multimeter/dp/B000OPDFLM I have one of those, it seems to work well.
[22:32:19] <zeeshan> the rp2 is also my pid controller
[22:32:26] <zeeshan> for the pressure
[22:32:57] <furrywolf> what's your maximum pressure?
[22:33:01] <zeeshan> 100
[22:33:03] <zeeshan> psi
[22:33:09] <furrywolf> so .1 PSI is .1%... have fun with that!
[22:33:58] <SpeedEvil> furrywolf: Err - the ADC utterly decouples the accuracy from the accuracy of the components on the Pi
[22:34:14] <furrywolf> SpeedEvil: I mean if he used a built-in one
[22:34:19] <SpeedEvil> There is none.
[22:34:30] <furrywolf> sure there is
[22:34:45] <zeeshan> what adc is in thre?
[22:34:51] <zeeshan> i havent seen any word about one! :P
[22:34:56] <furrywolf> doesn't it have a stereo audio chip? :P
[22:35:32] <furrywolf> or did they not include line-in?
[22:36:26] <zeeshan> http://www.phidgets.com/products.php?category=35&product_id=1048_0
[22:36:26] <furrywolf> bah, looks like the left out the line-in. nevermind.
[22:36:47] <zeeshan> this is what i wanna use for temp datalog
[22:37:44] <furrywolf> ... $100? the $33 multimeter I pasted comes with a thermo-probe of some form. :P
[22:37:45] -!- recon_lap [recon_lap!~mec@217.114.169.253] has parted #linuxcnc
[22:37:55] <zeeshan> can it handle 4 thermcouples?
[22:38:13] <zeeshan> $132 in multimeters? :)
[22:38:44] <furrywolf> no, but that's better than $400... lol
[22:38:48] <furrywolf> surely you can find a cheaper board
[22:40:22] <furrywolf> it suggests it has a k-type thermocouple good to 750C. I have mine somewhere, and it didn't look built able to withstand quite that high...
[22:40:38] <Rab> Ffffuuuuuuuuuuu, used threadlocker for some fasteners going through polycarbonate into aluminum. A tiny amount wicked out of one of the holes, under the plastic...instant stress cracking.
[22:40:46] <SpeedEvil> furrywolf: insulation varies
[22:41:00] <SpeedEvil> furrywolf: if it's got PVC wires, it's not going to 750C
[22:41:20] <SpeedEvil> Polycarbonate is a bitch
[22:41:25] <SpeedEvil> If you care about solvents
[22:42:10] <Rab> Wonder if there's some kind of paste compound I can apply down in the threads. No fasteners of this type available with threadlocking already applied, unfortunately.
[22:42:37] <furrywolf> Rab: hot glue
[22:43:09] <furrywolf> it doesn't bond as tightly as, say, red loctite, but it's quick to use and has no solvents. :)

[22:43:17] <Rab> furrywolf, interesting.
[22:43:22] <SpeedEvil> Or epoxy
[22:43:32] <SpeedEvil> If you don't actually want it out again
[22:43:41] <furrywolf> lol
[22:43:51] <furrywolf> I've used jbweld on things I explicitly DID want to come out again.
[22:44:01] <Rab> This is a prototype, but the screws in the final product shouldn't need to be removed.
[22:44:03] <SpeedEvil> Well - that too
[22:44:15] <Rab> Unless the polycarb cracks and needs to be replaced. ;)
[22:44:27] <furrywolf> epoxy is great for things with damaged threads. fill with epoxy, thouroughly grease the screw (making sure to get to the bottom of the threads), screw it in. let epoxy set, back out screw... perfect threads.
[22:44:43] <SpeedEvil> yeah - that can work well.
[22:44:50] <SpeedEvil> I've used that to make connectors too.
[22:45:13] <SpeedEvil> same way - cover the actual connector hole with tape, grease, press into epoxy
[22:45:23] <furrywolf> all the lights on my jeep cherokee were held in that way. jeep decided wood screws into fiberglass was the idea way to attach things. that works about once...
[22:45:33] <furrywolf> ideal
[22:45:54] <furrywolf> second time the screw just spins
[22:47:21] <furrywolf> Rab: or, if you have room, use nylocks instead of threadlock
[22:48:55] <Rab> furrywolf, the screws go into threaded aluminum mounting arms. I'd have to drill out the threads and find longer screws to use locknuts.
[22:50:04] <Rab> I wonder if I can apply threadlocker to the threads and let dry.
[22:53:23] <Computer_barf> so on a mill, should the table be moving forward or backwards when I press the + jog button?
[23:00:55] <zeeshan> tool should come towards you
[23:00:59] <zeeshan> table should go away from you
[23:01:07] <zeeshan> for Y.
[23:01:20] <zeeshan> (assuming your table moves in the Y direction)
[23:01:33] <SpeedEvil> https://www.kickstarter.com/projects/1598272670/chip-the-worlds-first-9-computer if the Pi is too expensive for your CNC
[23:01:42] <zeeshan> i could be wrong ;-)
[23:02:33] <Computer_barf> my table moves on the y direction. when I press Y+ on axis, the table moves twords me
[23:07:49] <Rab> Sounds right to me, table moving toward you means the tool makes a path toward Y+: http://www.cliffsnotes.com/assets/255358.png

[23:08:57] <zeeshan> sorry i was wrong
[23:08:59] <zeeshan> use right handle right
[23:09:01] <zeeshan> rule
[23:09:24] <zeeshan> when your tool moves to the right that is +x , tool away from you is +y , tool going up is +z
[23:09:56] <KimK_laptop> Yes, when you push jog something+, the *tool* should move in the something+ direction (even if the tool doesn't move at all).
[23:10:07] <Rab> And of course if the tool is fixed and the table moves, that's inverted.
[23:10:23] <zeeshan> :D
[23:11:28] <zeeshan> i notice that a lot of pid controllers directly have a thermocouple connected to it..
[23:11:37] <renesis> the z is the trucky one because it actually moved the tool not the work
[23:11:42] <renesis> typical mill
[23:11:49] <zeeshan> is an auxillary output for that temp sensor for datalogging purposes common?
[23:11:57] <renesis> trucky (c) rencorp
[23:27:07] <Computer_barf> what can be used to clear up some staining on the surface of the bed?
[23:29:34] <SpeedEvil> Computer_barf: put it through a hot-wash with extra detergent? Bleach the stained spots?
[23:29:40] <SpeedEvil> err - wrong channel
[23:30:02] <Computer_barf> surface of the bed of a mill lol

[23:32:33] <SpeedEvil> Beaching the stained spots will certainly do something.
[23:32:52] <Computer_barf> i think bleach on steel = rust
[23:33:30] <Computer_barf> transforming some slight discolaration from some spattered areas into rusty patches doesn't sound good
[23:33:57] <Computer_barf> im wondering what would be abrasive to gunk but not abrasive to steel
[23:34:31] <Computer_barf> ive heard of some people using steel wool but was thinking maybe find somehting more mild
[23:38:12] <SpeedEvil> brass wool can work.
