[00:09:48] <mark_____> hello
[00:10:30] <mark_____> looking for some help with a lathe config. trying to get ipr feed working

[00:17:08] <Mark_____> anyome here
[00:18:22] <andypugh> No, noibody here :-)
[00:19:09] <andypugh> Hmm, have we been talking abou this on the fotum
[00:19:13] <andypugh> (forum)
[00:20:23] <Mark_____> just trying to get it going. I have some work avaiable if I can get it threading
[00:21:04] <andypugh> Do you have a spindle encoder, with index ?
[00:21:09] <Mark_____> yes
[00:21:46] <Mark_____> hal scope picks it up and the gui??? shows me my spindle rpm
[00:21:55] <andypugh> And does that encoder read exactly one turn per turn, and one rpm per rpm?
[00:22:12] -!- tobias47n9e_ has quit [Ping timeout: 250 seconds]
[00:22:47] <Mark_____> yes as far as I can tell. There is a little descepence between what the machine speed and linux displ;ays
[00:23:00] <Mark_____> descrepency
[00:23:15] <andypugh> So, you need to connect the motion.spindle-speed in to the encoder velocity, motion.spindle-revs to the encoder position and motion.spindle-index-enable to the encoder index. Three lines of HAL. Job done.
[00:24:36] <Mark_____> when I tried a g98 (I think css mode) it still fed in inches per min. Not inches per rev.
[00:24:51] <Mark_____> might have been g99
[00:25:29] <andypugh> CSS is not the same as feed-per-rev.
[00:26:12] <andypugh> G95 for feed-per-rev: http://linuxcnc.org/docs/2.7/html/gcode.html
[00:26:54] <Mark_____> opps g95. I used the wrong one. I'll try again and brb
[00:27:01] <XXCoder> just curious
[00:27:10] <andypugh> I just read back, and earlier I meant motion.spindle-speed-in
[00:27:17] <XXCoder> does program adjust for surface speed as it cuts stock down into smaller diameter?
[00:27:25] <andypugh> Yes
[00:27:28] <andypugh> That’s the pont
[00:27:41] <XXCoder> interesting. thanks
[00:27:47] -!- chris_99 has quit [Quit: Leaving]
[00:28:59] <andypugh> XXCoder: You can hear it here: https://youtu.be/nIYMfyf4jDI?t=30s
[00:29:12] <XXCoder> heh hear
[00:29:30] <andypugh> Ah. You can potentially see it here: https://youtu.be/nIYMfyf4jDI?t=30s
[00:30:13] <XXCoder> looked like it was speeding uo nearer to center
[00:30:39] <andypugh> I just realised how much I use sound to judge how happy the machine is.
[00:31:45] <gonzo_nb> smell is important too
[00:31:57] <XXCoder> noes, the 2 senses I dont have
[00:32:05] <gonzo_nb> (as is smoke, when I'm taking deep cuts!)
[00:32:11] <Duc> you cant smell either?
[00:32:20] <XXCoder> nah I have lots fun problems
[00:32:42] <XXCoder> like back so bad I got arthitis of back when I was 27. I will be 40 soon.
[00:32:52] <Duc> after tomorrow I may have a fun video for everyone if it works
[00:33:42] <gonzo_nb> you're eye ok though?
[00:33:53] <andypugh> Sympathy on the back, mine has been terrible the last week or so. Standing up is OK, but I can’t escape from seats, or reach the floor.
[00:34:05] <XXCoder> far better than average eyesight
[00:34:06] <Duc> should be shooting my 20mm rifle I built myself if it does blow up we will have it on the gopro
[00:34:22] <andypugh> 20mm?
[00:34:32] <gonzo_nb> Good, I hoped you were not trying to machoine by brail !
[00:34:32] <andypugh> Is that the bore or the barrel length?
[00:34:38] <_methods> jeebus
[00:34:39] <_methods> 20mm
[00:34:47] <Duc> bore
[00:34:48] <_methods> thats antitank size
[00:34:57] <XXCoder> not in terms of focus but big eyesight focus and "active" 180 degree vision which is annoying by itself
[00:35:17] <Duc> http://s158.photobucket.com/user/Patriot222/media/Aircraftguns00211.jpg.html
[00:35:19] <Duc> sizing
[00:36:00] <gonzo_nb> what side of the pond are you on Duc?
[00:36:11] <Duc> US
[00:36:27] <andypugh> https://en.wikipedia.org/wiki/2_bore
[00:36:40] <gonzo_nb> XXCoder, you can still sit at the front seats in the cinema and not miss things
[00:37:01] <XXCoder> no captions are no fun
[00:37:01] <gonzo_nb> A bit easier to play shooting than in the UK
[00:37:12] <gonzo_nb> especially making your own stuff
[00:37:33] <XXCoder> and no, it does not work as everything is weirdly disorted by bad angle near front
[00:37:42] <Duc> yep none of that gun bullshit in AL
[00:37:56] <Duc> XXcoder texting had to be the best thing for you
[00:38:11] <XXCoder> Duc: no shit later 90s was great
[00:38:20] <XXCoder> finally, portable device works for deaf!
[00:38:24] <gonzo_nb> to make stuff in the uk you have to be a registered gun smith. Which they only give if you are really trade
[00:38:57] <XXCoder> tty was good from 60s to 90s but really its deaf tradition to just go to friend house and hope persons there
[00:39:07] <XXCoder> because phone line is expensive
[00:39:13] <Duc> and now you have tinder and online dating
[00:39:35] <Duc> gonzo_nb: Im somewhat in the trade anyways but I needed a way to justify the garage tools
[00:39:37] <gonzo_nb> ans carrying a mecahnical teletype is a bit difficult
[00:40:30] <gonzo_nb> hehe, I probably have a better workshop than most gunsmiths, but I'm not alowd to make stuff
[00:40:31] <XXCoder> heh 60s tty is a mini tank
[00:40:50] <gonzo_nb> I have a 1970's telex machine
[00:40:57] <XXCoder> weights around umm 800 pounds? kidding heh
[00:41:03] <gonzo_nb> it was in the living room till recently
[00:41:11] <XXCoder> I'm still sad my grandparents scrapped em
[00:41:19] <XXCoder> tank ttys is rare
[00:41:39] <gonzo_nb> I moved mine to the shed and it broke the wheel barrow!
[00:42:17] <Duc> LOL
[00:43:07] <gonzo_nb> late here. gn
[00:43:12] <andypugh> gonzo_nb: In practice you can make a gun if you want to. You just can’t let them find out.
[00:43:32] <gonzo_nb> min 5yrs jail
[00:43:45] <malcom2073> Emphesis on "can't" :P
[00:44:05] <andypugh> If they find out. How would they? And, anyway, you could always not make the firing pin.
[00:44:45] <gonzo_nb> cutting the chamber is an act of manufacture
[00:44:53] <Duc> they are really strict over there
[00:45:30] <andypugh> I wonder where I stand with this project? https://picasaweb.google.com/108164504656404380542/Sniper?authuser=0&authkey=Gv1sRgCJ6K36Pg5_T5ew&feat=directlink
[00:45:56] <andypugh> It’s a laser-tag rifle, but with a replica Lee-Enfield bolt action.
[00:45:56] <gonzo_nb> about the only homebrew gunsmithing op you can do is to drill the flash hole on a cannon
[00:46:09] <gonzo_nb> as they are not proof tested by law
[00:46:09] <Duc> what caliber
[00:46:17] <Duc> nice
[00:46:47] <DaViruz> in sweden you can make your own gun if you want to, but you have to apply for a owners license first. and assuming you are eligble to own weapons it isn't usually a problem
[00:47:23] -!- HSD has quit [Ping timeout: 255 seconds]
[00:48:18] <gonzo_nb> as long as it can't fire of be easilly adapted to fire, it's a replica gun, in uk law
[00:49:10] <Duc> this gun I had to apply for a destructive device before I could make the lower
[00:49:24] -!- HSD [HSD!~user@mrono.net] has joined #linuxcnc
[00:49:24] <gonzo_nb> you can't make usable stuff in the uk, even if you have a licence to own it
[00:50:24] <gonzo_nb> right GN people
[00:50:35] <Duc> time to move then
[00:50:42] -!- gonzo_nb has quit [Remote host closed the connection]
[00:53:45] <andypugh> Well, to be honest, I don’t feel that upset that I am not allowed to make a gnu.

[00:54:45] <malcom2073> Tbh, I only really one to make one because I'm not supposed to
[00:54:47] <Duc> Its a little different view living in the US but I only use guns for fun at the range
[00:55:14] <andypugh> Compared to, for example, the fact that two nice ladies turn up every morning to get my (geriatric, invalid) dad out of bed, and every night to put him back to bed, for no expense on my part or theirs.
[00:56:11] <malcom2073> Wait, aren't you like, ancient yourself?
[00:56:11] <malcom2073> :P
[00:56:36] <malcom2073> Ohh wait
[00:56:37] <malcom2073> that's archivist
[00:56:39] <malcom2073> not you, sorry

[02:01:36] <Jymmm> andypugh: WOW! You look MUCH older than your age ;)
[02:02:29] <Jymmm> Does anyone use radiant floor heating (heated water tubes in floor) ?
[02:02:51] <andypugh> Yes
[02:03:01] <Jymmm> andypugh: How do you like it?
[02:03:05] <andypugh> Moderately common in the UK
[02:03:23] <andypugh> It works well, and you don’t have any vsible radiators.
[02:03:25] <t12> i got the tiniest boring bar
[02:03:28] <t12> https://www.instagram.com/p/_8E7yBACtw/
[02:03:30] <Jymmm> andypugh: electric elements or liquid filled?
[02:03:35] <andypugh> Water
[02:03:57] <Jymmm> andypugh: any drawbacks or cavets you've found?
[02:05:16] <andypugh> My parent have it. We have had a couple of leaks with their (proprietary, no longer in business) system. Luckily all at the manifold not in the concrete
[02:05:47] <Jymmm> andypugh: Ah, ok. At first glance, wood fired with propane backup seems ideal for us
[02:06:15] <andypugh> t12: I see your huge boring bar and suggest: https://picasaweb.google.com/108164504656404380542/CNCUnsorted#6057493351291797154
[02:06:38] <t12> nice
[02:06:40] <t12> all in one lot?
[02:07:09] <andypugh> Yeah, eBay. £50
[02:07:18] <t12> nice
[02:07:21] <t12> i saw a lot of like
[02:07:26] <t12> 30 axa's go up
[02:07:30] <t12> for alot of money
[02:07:32] <t12> then sell instantly
[02:08:03] <Jymmm> andypugh: I came across this wood gasification boiler, not that I think I need THAT much... https://www.youtube.com/watch?v=-Rp1yBpP3xE
[02:08:38] <Jymmm> andypugh: Would rdianting heating work in the shop without mucking with the floor? Maybe on the wall or something?
[02:09:14] <andypugh> i would like underfllor for machine tools, it would keep the tools warmer than the air.
[02:10:11] <Jymmm> andypugh: Sure, I'm just not gonna muck with any concrete work at this time. I thought some radiator'ish thing might do on the wall.
[02:10:25] <andypugh> t12: P H Horm make a boring bar of 0.2mm holes.
[02:10:40] <andypugh> (P H Horn, I mean)
[02:10:45] <t12> that is
[02:10:48] <t12> very itty bitty
[02:11:17] <andypugh> I think they make it to show off. I can’t think of an application.
[02:12:08] <t12> i've been thinking of getting a little LWD microscope-usb thing now for the lathe
[02:12:16] <t12> so i dont have to get my face all up in the lathe
[02:12:25] <Jymmm> andypugh: They make pex-al-pex (HDPE-Aluminum-HDPE layered tubing) now too this is even certified for air lines , 120PSI iirc.
[02:12:27] <t12> but really i want one thats just hdmi out to a panel
[02:12:56] <Jymmm> t12: got a android tablet?
[02:13:04] <t12> not on hand but could
[02:13:09] <t12> is there a good tablety one?
[02:13:12] <Jymmm> t12: hang on...
[02:14:29] <Jymmm> t12: They make them in 1 to 15m in length, cheaper off ebay... http://www.amazon.com/BlueFire-Android-Endoscope-Phones-Function/dp/B013HZCYXK/
[02:14:33] <andypugh> Jymmm: Yes, the Kee system we used (triple tube, quite neat, and a goood idea) has basically been replaced by HDPE barrier piping. http://www.wavin.co.uk/web/solutions/heating-cooling/underfloor-heating/manifolds-and-controls-hep2o.htm
[02:14:58] <t12> oh cool
[02:15:04] <t12> thats awesome
[02:15:24] <Jymmm> t12: I thought you could just get a cheap 7" tablet and use as the screen mounted on a gooseneck off the lathe
[02:15:35] <t12> yeah
[02:15:39] <andypugh> t12: A chap I know uses a microscope on his lathe because he makes tiny things.
[02:15:40] <t12> maybe cheap amazon tablet
[02:15:52] <Jymmm> t12: They even have "right angle" mirrors you can attach to the tips
[02:16:05] <andypugh> Not sure what he uses. But he spends a lot of money on his hobby.
[02:16:18] <t12> i got some grade 2 ti to turn
[02:16:23] <Jymmm> t12: When I say cheap tablet, I mean like $24USD =)
[02:16:24] <t12> i wonder how terrible/not terrible this will be
[02:16:46] <Jymmm> t12: I think Loetmichel2 has one on his, ask him
[02:16:47] <t12> i wionder what the cheapest ip67 ish tablet is
[02:17:02] <Jymmm> t12: ziplock bag = IP67 =)
[02:17:34] <andypugh> Pictures 6-onwards here are from his lathe microscope. Yes, he really is making O-rings smaller than you can buy… http://www.f1-2000.co.uk/index.php?f=fuel_injectors
[02:18:07] <Jymmm> andypugh: I know where to get orings from =)
[02:18:24] <Jymmm> andypugh: they'll even custom make them
[02:18:50] <andypugh> Too late, he already made his own..
[02:19:19] <t12> lol:
[02:19:19] <Jymmm> andypugh: OH, zoning... how do you keep the water hot from beginning to end?
[02:19:20] <t12> You soon realise that you’re onto a hiding to nothing with your 30 quid Jacobs chuck and start learning lots of new words like “Albrecht” and “Schaublin”.
[02:20:01] <Jymmm> andypugh: If it's 120F going in and 90F coming out as example.
[02:20:04] <t12> why bother making a fullsize f1.... when you can make a 1/4!
[02:20:30] <t12> might as well ebeam mill it at some point
[02:20:32] <andypugh> Jymmm: Well, the Kee system had three tubes side-by-side extruded as a set, and you ran the outers one way and the inner the other, so it kind of evened-out.
[02:20:51] <Jymmm> andypugh: Ah, makes total sense.
[02:21:02] <Jymmm> andypugh: three???
[02:21:26] <andypugh> Yes, not sure why three and not two.
[02:21:40] <Jymmm> andypugh: Heh, okey we're thinkng the same on that =)
[02:22:30] <Jymmm> andypugh: We think the wood fired stove might have been making the birds sick. So looking at alternatives.
[02:22:52] <Jymmm> very sensative respritory systems (aka canary in a coal mine)
[02:23:28] <andypugh> We like it, in my parents house. if I was (like them) in a situation where my house had no floors, I would probably install it.
[02:24:24] <Jymmm> andypugh: This is a mobile home, so I can install UNDER the existing flooring in the crawlspace, then insulate under that.
[02:25:16] -!- Duc has quit [Ping timeout: 250 seconds]
[02:25:44] <Jymmm> andypugh: then I dont have to muck with the existing flooring
[02:26:09] <Jymmm> ...and do a little bit at a time

[02:26:27] <Jymmm> with nobody screaming "are you done yet?" lol
[02:28:23] <andypugh> You need to have a lot of insulation under the pipes to send the heat the right way. My parents’ floor is hardcore, blinded with sand, then a membrane, then 3” of poly-something foam, then 4” of concrete, them the pipes, then a screed, then the flor covering.
[02:28:51] <andypugh> Int their case the floor covering is 2” of stone flags, but that’s a local peculiarity.
[02:31:35] -!- irontree9 has quit [Ping timeout: 240 seconds]
[02:34:24] <Jymmm> andypugh: Ah, yeah. Well in this case I suspect it's particalboard flooring, so have the tubes underthat, and sheet insulation under that.
[02:35:47] <Jymmm> andypugh: I have seen these aluminum extrusions that the tube sit in to act as radiators and heat spreaders.
[02:36:30] <Jymmm> andypugh: http://www.builditsolar.com/Projects/SpaceHeating/DHWplusSpace/P1060005.JPG
[02:36:59] <andypugh> I have only seen those for electrical versions, but then I haven’t really been looking. When it is all in concrete and under stone then spreaders are pointless anyway.

[02:45:38] <Jymmm> I was thinking of using https://www.sparkfun.com/products/245
[02:46:01] <Jymmm> then you can really monitor/tweek areas
[02:46:31] <andypugh> Aye, something like that would be part of my installaion, if i went that way.
[02:47:24] <Jymmm> and a big ass deep cycle battery for backup of the electronics, pumps, acuators.
[02:49:16] <Jymmm> andypugh: does it snow where you are using it?

[03:05:51] <malcom2073> Jymmm: Yeah I found a guy who pays for them, not as much as lead cells, but he'll still pay

[03:06:48] <Jymmm> get oen of those
[03:06:50] <malcom2073> It does up to 500A loads
[03:07:09] <Jymmm> doesn't measure watts draw does it?
[03:07:28] <malcom2073> It loads the battery, and can tell if the battery is any good
[03:07:41] <Jymmm> malcom2073: Yeah, no. that's nto what oyou want.
[03:07:46] <malcom2073> To tell if they're good?
[03:08:00] <Jymmm> To REVIVE the battery
[03:08:05] <malcom2073> Ohhhh
[03:08:06] <malcom2073> yeah
[03:08:12] <Jymmm> this takes like two weeks to do
[03:08:12] <malcom2073> If they're toasted yeah
[03:08:49] <Jymmm> put anderson power poles on each end too
[03:09:48] <malcom2073> I like those connectors
[03:09:52] <Jymmm> malcom2073: Per this specification... http://www.qsl.net/w2vtm/powerpole.html
[03:10:02] <malcom2073> Yeah
[03:10:44] <Jymmm> malcom2073: I have all kinds of jumpers, adapters using that spec and PP (power poles)
[03:10:50] <malcom2073> Yeah we use them at work
[03:10:57] <Jymmm> malcom2073: you do?
[03:11:04] <Jymmm> malcom2073: what amperage?
[03:12:34] <malcom2073> Mainly their 30A stuff, but some of our larger equipment uses the 120A ones
[03:12:54] <Jymmm> malcom2073: Dude! Buddy, Pal O Mine!!!
[03:13:06] <malcom2073> But I was thinking: use this battery pack to run my gas furnace
[03:13:12] <malcom2073> Then I'd not need to run my generator overnight
[03:13:21] <Jymmm> malcom2073: I need some 120A stuff =)
[03:13:24] <malcom2073> Only every couple hours to keep the fridge/freezer cold
[03:13:29] <malcom2073> haha, I can't take any of it, it's all govt. property :P
[03:13:32] <malcom2073> inventoried and crap
[03:13:49] <malcom2073> I can probably crimp them for ya though if you need
[03:13:58] <Jymmm> malcom2073: I'll take the crap that doens't pass QC =)
[03:14:15] <malcom2073> We're R&D, if it doesn't pass QC, you wouldn't want it
[03:14:23] -!- tperry has quit [Client Quit]
[03:14:27] <Jymmm> malcom2073: the hell I wouldn't =)
[03:14:33] <malcom2073> Lol
[03:14:51] <Jymmm> malcom2073: I want 120A for jumper cables for the car, plus maybe for the inverter
[03:16:17] <malcom2073> They're not *terribly* expensive, something like $20 each conector including contact
[03:16:32] <Jymmm> malcom2073: and if you have any spare 30A contacts that just get swept off the floor, I'll be happy to sort thru the dirt pile =)
[03:17:15] <malcom2073> I wish
[03:17:15] <Jymmm> malcom2073: Yeah, times 4, plus the shells. and that's if I dont fuck up crimping them the first time =)
[03:17:19] <malcom2073> Nothing good ever gets thrown out
[03:17:34] <malcom2073> 20 includes the shells, so $80 per connectio nset heh
[03:17:51] <Jymmm> malcom2073: I can open the hood of my car for that =)
[03:18:39] <Jymmm> malcom2073: Actualy, I have the shells, just need the terminals.
[03:19:07] <Jymmm> malcom2073: how many watts is your gas furnace?
[03:19:12] <malcom2073> only 4kw
[03:19:16] <Jymmm> and is the blower 110 or 220 ?
[03:19:32] <malcom2073> 110 only :( I wish it was 220 to run my waer pump
[03:19:32] <Jymmm> 4KW?! for GAS ?!???????????
[03:19:33] <malcom2073> water*
[03:19:51] <malcom2073> ?
[03:19:58] <malcom2073> oh hahah
[03:19:59] <malcom2073> furnace
[03:20:00] <malcom2073> I read generator
[03:20:03] <malcom2073> I haven't a clue
[03:20:20] <Jymmm> then how do you know how much power you need for it?
[03:20:43] <malcom2073> Because it only has a 200w water pump, and a <1a ignitor
[03:20:51] <Jymmm> and a blower
[03:20:54] <malcom2073> No
[03:20:58] <malcom2073> Hot water baseboard
[03:21:02] <malcom2073> Hence, the water pump
[03:21:04] <Jymmm> oh radiate heat
[03:21:08] <malcom2073> yeah
[03:21:27] <malcom2073> Totally silly to run my generator just for that
[03:21:32] <malcom2073> batteries would be much better
[03:21:36] <Jymmm> so 200W / 120V = 2A
[03:21:51] <Jymmm> That's a cheap inverter easily
[03:21:56] <malcom2073> Indeed!
[03:22:07] <malcom2073> That's the plan, cheap inverter + high power battery charger
[03:22:16] -!- tperry74 has quit []
[03:22:18] <Jymmm> no need for hight power charger
[03:22:28] <malcom2073> Eh, so it can top off the bank during the occasional generator running
[03:22:39] <malcom2073> Tbh, I don't even need a battery bank
[03:22:54] <malcom2073> how long would a 60AH car battery run on say, 400watts draw?
[03:23:00] <malcom2073> assuming terrible inverter efficiency
[03:23:05] <Jymmm> http://www.autozone.com/test-scan-and-specialty-tools/battery-charger/schumacher-75-12-2-amp-fully-automatic-battery-charger-engine-starter/989_0_0/?checkfit=true
[03:23:26] <Jymmm> malcom2073: 30 hours less loss of the inverter itself
[03:23:32] <malcom2073> Yeah
[03:23:52] <malcom2073> I could probably get by with 1-2 batteries, + charging during the once every few hours the generator is on for a bit
[03:24:15] <Jymmm> No, let the battery charger operate it 24/7/365
[03:24:26] <malcom2073> I mean when the power is off
[03:24:34] <Jymmm> me too
[03:24:52] <Jymmm> Then it's a backed system hands off.
[03:25:01] <malcom2073> Oh, yeah it would be
[03:25:13] <Jymmm> at the cost of extra KW running it for years
[03:25:37] <malcom2073> Meh, I'd get myself a charger that can switch between fast charge and float as needed
[03:25:39] <Jymmm> But, I'd rather have heat all on it's own
[03:25:48] <malcom2073> OH
[03:25:53] <malcom2073> you mean run the furnace off the batteries all the time
[03:25:55] <Jymmm> read the link... FULLY AUTOMATIC
[03:25:55] <malcom2073> yeah
[03:26:11] <malcom2073> Fully automatic means it goes from full charge to trickle, almost never the other way around
[03:26:14] <Jymmm> actually, that one is WAY over kill
[03:26:31] <Jymmm> it will, if the battery is low
[03:26:53] <Jymmm> and an inverter will suck the life out of batteries =)
[03:27:07] <Jymmm> NEVER EVER trust the "low battery" shutoff on inverters =)
[03:27:12] <malcom2073> I actually already have a AC switching setup that will flip the furnace over to the batteries in case of a power loss designed and half built

[03:28:48] <malcom2073> Lol
[03:29:00] <malcom2073> There ya go! you're set... but do you have a radiant heat furnace? :P
[03:29:10] <Jymmm> malcom2073: It's the 3KW inverter I need to make cables for =(
[03:29:18] <malcom2073> Yowch heh
[03:29:21] <Jymmm> malcom2073: Fuck you and the boiler you rode in on!
[03:29:25] <malcom2073> Lol
[03:29:51] <Jymmm> malcom2073: Yeah, I was thinking of making some using the 8ga cable I have a spool of
[03:30:05] <Jymmm> 8ga+8ga+8ga =)
[03:30:17] <Jymmm> that's about 4ga I'd guess
[03:30:32] <malcom2073> heh
[03:30:50] <Jymmm> good for 4.2 minutes on one battery =)
[03:31:02] <Jymmm> maybe 1.2 minutes =)
[03:31:05] <malcom2073> hah
[03:31:13] <malcom2073> bonus: battery will double as a heater afterwards
[03:31:31] <Jymmm> if the cables power ing dont start glowing first
[03:32:17] <Jymmm> Maybe I'll lok for broken jumper cables at a yard sale
[03:32:21] <Jymmm> look*
[03:33:14] <malcom2073> I still need to clean up the regulation on my generator, it's damn dirty
[03:33:46] <Jymmm> malcom2073: http://www.harborfreight.com/200-watt-continuous400-watt-peak-power-inverter-61478.html
[03:34:01] <malcom2073> I got one of those heh
[03:34:08] <Jymmm> how are you going to clean it up?
[03:34:33] <Jymmm> plug your furnce into that directly, but maybe get the bigger one
[03:34:36] <malcom2073> It's a 70's generator, probably just taking apart and cleaning up the governer would make it work a bit better
[03:35:01] <Jymmm> http://www.harborfreight.com/400-watt-continuous-800-watt-peak-power-inverter-66814.html
[03:35:40] <Jymmm> 2KW/4kw not too bad reviews http://www.harborfreight.com/2000-watt-continuous4000-watt-peak-power-inverter-69662.html
[03:36:12] <Jymmm> Still Modified sine wave, so be leary of that.
[03:36:43] <malcom2073> I'm doing research on actually replacing the bridge rectification circuit for the exciter
[03:36:47] <malcom2073> apparently those go a bit wonky as they get old
[03:37:08] <malcom2073> yeah modified sine is ugly, but would work
[03:37:15] <Jymmm> malcom2073: What I actually thought of doing is getting a quality inverter and wire that into one circuit inthe electric panel. then I ALWAYS have lights
[03:37:42] <malcom2073> Jymmm: Oh, have like backup lights always wired to the generator?
[03:37:45] <Jymmm> and in your case, your furnace too
[03:37:56] <Jymmm> malcom2073: No, like
[03:38:00] <malcom2073> They make panels with safeties to allow switchovers
[03:38:21] <Jymmm> malcom2073: In homes, the ceiling lights in the entire home are on one circuit (breaker).

[03:38:41] <malcom2073> Heh, lucky. Mine are on like, 5
[03:38:47] <malcom2073> old houses suck
[03:39:42] <Jymmm> malcom2073: the output of the circuit breaker would go to charge the batteries that powers the inverter. The output of the interver would be wired into the cuircut that would normally be connected to the output of the breaker
[03:39:52] <malcom2073> Ah gotcha
[03:40:13] <Jymmm> Basically a UPS
[03:40:20] <malcom2073> yeah
[03:40:28] <malcom2073> Ohhh there's a better idea
[03:40:31] <malcom2073> I have a 3kw UPS
[03:40:38] <malcom2073> I wonder how clean its inverter is
[03:40:39] <Jymmm> but semi-erm wired into one circuit in the breaker box
[03:41:01] <Jymmm> malcom2073: check with batteries connected AND disconnected
[03:41:12] <malcom2073> I have no batteries for it atm, gonna have to wait until I get some lol
[03:41:15] <Jymmm> UPS are usually sinewave
[03:41:33] <Jymmm> that big anyway
[03:41:39] <malcom2073> Yeah
[03:41:48] <malcom2073> It has bad batteries in it right now, weighs like 120lbs
[03:41:58] <Jymmm> An an APC UPS
[03:42:04] <Jymmm> 8 battereis
[03:42:17] <Jymmm> wired in 24/48v configuration
[03:42:47] <malcom2073> Hmm, 5000VA
[03:42:47] <malcom2073> http://www.bhphotovideo.com/bnh/controller/home?O=&sku=613890&gclid=Cj0KEQiAno60BRDt89rAh7qt-4wBEiQASes2tZuw31_8esyGKmOqzoNCVR2fQCXxqw5JQNcw_EGBdqIaAioP8P8HAQ&Q=&ap=y&is=REG&A=details
[03:42:49] <malcom2073> One of them
[03:43:08] <malcom2073> Except 110V input, which is *odd*, becuase that'd be more than a 20A circuit could handle
[03:43:26] <Jymmm> ( ( (12+12) + (12+12) ) + ( (12+12) + (12+12) ) )
[03:44:09] <Jymmm> malcom2073: 3000VA != 3KW =)
[03:44:27] <Jymmm> but I had 3KW 120V APC UPS too =)
[03:44:29] <malcom2073> Psh, my power factor is 1.0 beotch!
[03:44:40] <Jymmm> not even in your wet dreams!
[03:44:47] <Jymmm> maybe .1
[03:44:48] <malcom2073> haha
[03:45:20] <Jymmm> yeah, run that UPS as the output of your gen and you'ld have a killer setup
[03:46:14] <malcom2073> The generator has a 12VDC decent amp output for its exciter and for charging its lead cell starting battery, I wonder how many amps it actually is
[03:46:49] <malcom2073> The UPS won't run off the generator, few will
[03:47:06] <malcom2073> Especially APC's, they want clean power
[03:47:10] <Jymmm> I bet it will with batteries installed
[03:47:27] <malcom2073> I've had very little luck with them running off generators, and at work we've tried a lot :)
[03:47:27] <Jymmm> Then hell, they use the batteries to deliver clean power
[03:47:33] <malcom2073> That's what I thought!
[03:47:37] <Jymmm> malcom2073: really?
[03:47:42] <malcom2073> Yeah, they usually fault out
[03:47:49] <Jymmm> bastrds
[03:47:50] <malcom2073> Honda inverter generators *sometimes* will work
[03:47:59] <malcom2073> but a non inverter generator? hell no
[03:48:00] <Jymmm> eu2000i ?
[03:48:09] <malcom2073> And don't even *think* about running it on a modified sine wave inverter
[03:48:12] <malcom2073> yeah
[03:48:14] <Jymmm> hahaha
[03:48:22] <malcom2073> We have 1k, 2k, and 3k eu's
[03:48:31] <Jymmm> Cool, that's what I have now, but I have been looking at a propane powered one
[03:48:40] <malcom2073> Used to have a 6k, it disappeared after the last layoff, bastards
[03:48:50] <malcom2073> They make propane kits
[03:48:55] <malcom2073> I got one for my generator, it's pretty slick
[03:48:56] <Jymmm> malcom2073: whats that big box behind you I see ?
[03:49:09] <malcom2073> hah I wish
[03:49:17] <malcom2073> I wouldn't be using a 1970's 4kw if I had that :-D
[03:49:51] <Jymmm> malcom2073: There is a 4KW one too http://www.amazon.com/gp/product/B00LT8S7IY
[03:50:44] <Jymmm> malcom2073: 4KW propane http://www.amazon.com/dp/B009RBKGZC
[03:50:56] <malcom2073> Heh
[03:51:10] <malcom2073> I got a conversion kit for $80, made an aluminum adapter on the mill, and boom, mine is propane too
[03:51:12] <Jymmm> malcom2073: the only bitch I've seen is ppl dont like how/where the battery is , hard to get to
[03:51:36] <Jymmm> but that's easy to fix for us
[03:52:00] <malcom2073> 240/30a could do my water pump heh
[03:52:03] <Jymmm> malcom2073: they even include the regulator and hose
[03:52:11] <malcom2073> yeah
[03:52:12] <Jymmm> for propane
[03:52:26] <malcom2073> propane is *so* much more convenient than gasoline
[03:52:26] <Jymmm> and electric start
[03:52:40] <Jymmm> but still has pull start for backup
[03:52:50] <malcom2073> Heh, mine has no pull start
[03:52:57] <malcom2073> its electric start uses the generation motor
[03:53:03] <Jymmm> https://www.youtube.com/watch?v=ZgKe9U4d7es
[03:56:52] <malcom2073> I think I'm gonna do that tomorrow, take apart this APC, stick it on a spare car battery, and hook it to the generator and see if it'll run
[03:57:07] <malcom2073> the battery warehouse near me has APC replacement batteries for a fraction of the cost, including the connectors

[07:17:18] <anomynous> Jymmm, totally off-topic? =)
[07:17:55] <anomynous> you could use router the cut the guitar profile or the hole in the middle or cut electric guitar frame :)
[07:19:08] <XXCoder> make wood boiler with cnc router
[07:19:43] * Jymmm tosses tree on cnc router and begins to carve boiler!
[07:22:10] <anomynous> arent those burners?
[07:22:31] <XXCoder> it makes burnable gas from wood
[07:23:22] <XXCoder> part of it does anyway, to recover as much energy from wood as possible
[07:23:32] <XXCoder> not too sure exactly
[07:24:11] <anomynous> isnt that kind of same as if it had secondary and tertiary air intake? :D
[07:30:41] <Jymmm> XXCoder: The 'wood gas' is produced when wood is burned at hot temperatures. it accoutns for 60% of the energy in wood.
[07:30:57] <XXCoder> pretty major
[07:31:30] <Jymmm> XXCoder: The air is super heated which allows the the secondary burners to (in essense) ignite or burn the wood gas.
[07:31:58] <anomynous> http://hotstovedeals.blogspot.fi/2009/07/primary-air-secondary-airairwash.html :D such comlicated thing to burn wood
[07:32:22] <Jymmm> XXCoder: When wood gas is not combused properly, it leaves creosite and over nasties
[07:32:28] <Jymmm> other*
[07:32:39] <XXCoder> fun. so whats your plan
[07:32:51] <XXCoder> by one of those so you dont have creosie problem?
[07:32:54] <XXCoder> *buy
[07:33:34] <Jymmm> XXCoder: No/maybe, not creosite, but radiant floor heating, but use wood boiler as primary, and propane as backup
[07:34:01] <Jymmm> XXCoder: No more burning wood or open flame indoors.
[07:34:15] <XXCoder> you dont need to ding me each time :P
[07:34:36] <Jymmm> XXCoder: No more watching the heat pump just suck the electricity inefeeciantly.
[07:35:15] <Jymmm> XXCoder: But it's all going to come down to the wood boiler itself
[07:35:16] <anomynous> Jymmm, do you have your own logs?
[07:35:25] <anomynous> or do you buy them
[07:35:25] <Jymmm> anomynous: As in wood? yes.
[07:35:27] <XXCoder> yeah it would take over for certain temp range below heat pump
[07:35:46] <Jymmm> anomynous: Buy wood, but it's far cheaper than propane
[07:36:00] <anomynous> ah... i thought you might make your own logs
[07:36:44] <XXCoder> can burn wood chips from your machine too
[07:36:46] <Jymmm> anomynous: Almond wood has 32.9M BTUs and goes for about $240 cord/delivered
[07:36:54] <XXCoder> theres special equipment to turn chips to "logs"
[07:37:01] <XXCoder> lemme find it
[07:37:09] <anomynous> whats btu and whats cord?
[07:37:10] <anomynous> :D
[07:37:25] <Jymmm> cord = 128 cubic feet
[07:37:33] <archivist> british thermal units
[07:37:37] <Jymmm> 8ft x 4ft x 4ft
[07:38:02] <anomynous> XXCoder, chipper?
[07:38:14] <XXCoder> https://woodgears.ca/reader/alois/press.html
[07:38:38] <Jymmm> XXCoder: If I want ecobricks, they're $2.99 for 6 (20.4 lbs)
[07:38:54] <XXCoder> they designed it to use up chips they make making stuff with manual tools, but cnc chips will work for it too
[07:39:17] <Jymmm> XXCoder: http://www.tractorsupply.com/tsc/product/redstone-wood-fuel-pack-of-6
[07:39:59] <XXCoder> I know that exists, but what I linked is great way to use up chips you make with wood projects
[07:40:05] <anomynous> wouldnt it be fun to use this? https://www.youtube.com/watch?v=bKyBEAtYfIs
[07:40:13] <anomynous> ;D
[07:40:25] <Jymmm> XXCoder: I'm in the forest, no need =)
[07:40:27] <XXCoder> so basically this machine shits wood
[07:40:40] <XXCoder> and its free once machine is made
[07:40:49] <Jymmm> XXCoder: My outdoor xmas trees are 100ft tall =)
[07:40:55] <XXCoder> nice
[07:41:31] <XXCoder> city I live in is one of earliest west settlement so it used to have tons of big trees
[07:41:39] <XXCoder> still some left but largely cut down
[07:41:52] <XXCoder> Fort Tacoma
[07:42:06] <Jymmm> those are pellets, they have pellet making machine on ebay
[07:42:14] -!- Komzzpa has quit [Ping timeout: 245 seconds]
[07:42:40] <XXCoder> funny because I moved from vancouver which IS oldest west settlement, and school I graduated from is built right in second Fort Vancouver site.
[07:42:53] <XXCoder> first one was burned down by native americans
[07:43:07] <Jymmm> rightly so!

[07:43:14] -!- SEL has quit [Quit: Leaving]
[07:43:15] <XXCoder> heh
[07:43:41] <XXCoder> anyway its because of that fact that each time school builds or demos building they have t o check over site for artifacts
[07:43:41] <Jymmm> XXCoder: Now, find my a DIY wood boiler running 5+ years and 99% effeciant =)
[07:43:57] <XXCoder> 5+ years a log? sure heh
[07:44:21] <Jymmm> No, just the design running for 5+ years
[07:44:34] <Jymmm> not like a v1.2, 1.3, 1.4 etc
[07:46:52] <XXCoder> https://woodgears.ca/reader/alois/26-b.jpg wood poop
[07:51:10] <anomynous> how about burning turf
[07:51:21] <anomynous> its being sold as pellets also
[07:51:26] <anomynous> ?
[07:52:15] <XXCoder> I know some areas use peat
[07:52:24] <XXCoder> which isnt quite same, but turf directly? dunno
[07:53:58] <anomynous> they harvest turf here and burn it. In big heat burners that heat towns, but that turf can be unpelleted or big blocks :D Unpelleted needs a special burner that i think cannot be done at home. Pelleted turf could be burned at home
[07:54:54] <XXCoder> I wonder if they could evenually run out of turf
[07:54:57] <anomynous> https://fi.wikipedia.org/wiki/Turve#/media/File:Toppila_power_plant.JPG this thing runs on turf

[08:33:13] <pink_vampire> there is a limit to the amount of sensors that I can connect in series? DS18B20??
[08:38:45] * archivist points at the data sheet
[08:47:53] <pink_vampire> archivist: theoretically you can connect a-lot of them.. but practically it's not working
[08:50:32] <archivist> phantom power or proper 5v
[08:54:48] <renesis> as if phantom power is this proper thing
[08:57:43] <archivist> would be better if the phantom power option allows for an external capacitor
[08:59:47] <renesis> coupling cap?
[09:00:04] <renesis> but then its not really phantom power so much as just a power supply
[09:01:27] <archivist> it takes its power from the serial line, it needs a larger cap so it can drive the pull up properly
[09:01:43] <archivist> in phantom/parasitic mode
[09:02:49] <enleth> or just use a 4-20 sensor
[09:03:15] <archivist> she wants to use many sensors
[09:03:59] <archivist> anyway with many they are in parallel not series
[09:04:15] <enleth> oh, by the way, are there 4-20 interfaces on any mesa board?
[09:06:04] <archivist> 4-20 is such an old standard, really stood the test of time

[18:11:15] <malcom2073> I wonder if I could use a DCDC to fool the UPS into thinking the batteries were always half full
[18:11:25] -!- PetefromTn_ has quit [Quit: I'm Outta here!!]
[18:13:54] <SpeedEvil> malcom2073: it typically may have a relay to disconnect the input
[18:14:17] <SpeedEvil> malcom2073: It will in many cases on boot turn off the input relay, and turn on the inverter, as a test to see if everything works
[18:14:34] <SpeedEvil> If there are no batteries - well - ...
[18:15:12] <Jymmm> malcom2073: How many batteries does it take? 8 ?
[18:16:30] <SpeedEvil> Also.
[18:16:39] <SpeedEvil> You can get batteries for testing from a car salvage yard
[18:17:08] <SpeedEvil> Ask what they pay for car batteries (they buy for the lead) then offer a modest premium
[18:20:52] <Jymmm> malcom2073: If it's anything like the 2KVA APC UPSes I had, You'll find there are two harnesses, each one goes to four batteries. Each harness is wired in a series/parallel for 24V ((2x12V) + (2x 12V)), then internally those two harnesses are wired for 48V.
[18:21:54] <malcom2073> Jymmm: Looks like four, two of the twofers that my 1500 takes
[18:22:02] <malcom2073> Wired for 12v each, 24v series internally
[18:22:05] <malcom2073> Which is odd
[18:22:18] <malcom2073> because the extra battery input says 48v, so you may be right, this one is supposed to take quad battery packs
[18:22:44] <Jymmm> and you need two "quad packs" ?
[18:22:49] <malcom2073> SpeedEvil: This all came about, because I may be picking up a pallet of coule year old unused gel cell batteries
[18:24:08] <SpeedEvil> malcom2073: it's not completely unlikely they are junk if they've not been charged
[18:24:28] <SpeedEvil> If they are under 11V or so terminal, they are almostr certainly junk
[18:24:35] <ReadError> can a MESA wizard sanity check my setup

[18:48:03] <ReadError> nah i ordered the 7i76e and 7i76
[18:48:16] <ReadError> I need 4 stepgen and 2 servos+encoders

[18:50:19] <neverbuya_subaru> ReadError: so whats the problem :P
[18:50:30] <ReadError> neverbuya_subaru, i just dont know of that combo is workable
[18:50:42] <neverbuya_subaru> ReadError: i was under the impression the the 7i76
[18:50:44] <neverbuya_subaru> had 5 encoder inputs
[18:50:47] <ReadError> i got the 26pin -> db25 cable
[18:50:50] <Tom_itx> you may have to make a bitfile for it
[18:51:09] <neverbuya_subaru> do your servos need step dir input
[18:51:11] <neverbuya_subaru> or analog
[18:51:21] <ReadError> neverbuya_subaru, they are digital, i think
[18:51:26] <ReadError> i know they take step/dir
[18:51:31] <neverbuya_subaru> can't think
[18:51:32] <ReadError> but theres a bunch of other pins
[18:51:33] <neverbuya_subaru> you should know that
[18:51:36] <neverbuya_subaru> its important
[18:51:51] <neverbuya_subaru> bust out the wiring diagram page of your motor driver
[18:51:58] <neverbuya_subaru> can you post that here?

[18:52:47] <MikkoP> Happy new year :D
[18:54:01] <ReadError> · Two single-ended analog inputs, +/-10 volt logic: Analog IN1 and Analog IN2.
[18:54:01] <ReadError> Support 0-10, +/-5, or 0-5 volt logic as well. Can be wired together to create one differential ana-
[18:54:01] <ReadError> log input. Analog velocity or position command signal. Note: the analog inputs are currently not
[18:54:01] <ReadError> supported by the Si ProgrammerTM software.
[18:54:13] <ReadError> http://www.applied-motion.com/sites/default/files/hardware-manuals/SV7_HardwareManual_920-0012.pdf
[18:54:21] <ReadError> seems it supports both, but ive never used servos before
[18:55:05] <neverbuya_subaru> i don't know the reason for this
[18:55:13] <neverbuya_subaru> but ive been told running analog is better
[18:55:19] <neverbuya_subaru> vs step dir
[18:55:22] <ReadError> nothing has shipped yet so I want to get the mesa stuff figured out ;)
[18:55:29] <neverbuya_subaru> but i wish sojmeone can give a concrete answer about that.
[18:55:35] <ReadError> well nothing from MESA has shipped*
[18:55:39] <ReadError> i have the servos+drives
[18:55:41] <neverbuya_subaru> if youre running servos
[18:55:50] <neverbuya_subaru> you should get the 7i77 + 5i25 or 6i25
[18:55:58] <neverbuya_subaru> because it comes with 6 channels of encoder inputs
[18:56:03] <neverbuya_subaru> and 6 analog outs
[18:56:04] <ReadError> i would like to stay ethernet though
[18:56:20] <ReadError> I have a crappy EEEpc that runs with great latency
[18:56:36] <ReadError> and dont want to stand up another box just for a pci card
[18:57:29] <neverbuya_subaru> i really dont know by step/dir is not as good
[18:57:35] <neverbuya_subaru> to make it is a digital signal
[18:57:37] <neverbuya_subaru> so it should be better.
[18:57:45] <neverbuya_subaru> less suspectible to noise unlike the analog signal
[18:57:55] <neverbuya_subaru> but at the same time, the analog signal is differential so its pretty immune to noise
[18:58:22] <neverbuya_subaru> your drives take step/dir
[18:58:29] <neverbuya_subaru> so i can see the 7i76e working.
[18:58:33] <ReadError> i cant think of any reason analog would be better
[18:58:50] <ReadError> step/dir are differential inputs also
[18:59:01] <neverbuya_subaru> lemme see if the 7i76e
[18:59:05] <neverbuya_subaru> is differential step/dir
[18:59:29] <neverbuya_subaru> All step and direction outputs are buffered 5V signals that can drive 24 mA. All outputs support differential mode to reduce susceptibility to noise.
[18:59:30] <neverbuya_subaru> awesome
[18:59:39] <neverbuya_subaru> so basically in your pdf
[18:59:48] <neverbuya_subaru> if you go to page 28
[19:00:04] <neverbuya_subaru> Connecting to Indexer with Differential Outputs (Many High Speed Indexers have Differential Outputs)
[19:00:17] <neverbuya_subaru> that's how you'd wire your 7i76e card to your db25 conenctor
[19:00:22] <ReadError> yea thats what i was planning on doing

[19:00:29] <neverbuya_subaru> so what is the problem!
[19:00:30] <ReadError> i was just unsure about daughter card choice
[19:00:41] <ReadError> i know im going with 1x 7i76e
[19:00:42] -!- asheppard_ has quit [Remote host closed the connection]
[19:00:43] <neverbuya_subaru> you want the 7i76e
[19:00:49] <neverbuya_subaru> 7i76 does not have encoder input
[19:00:52] <ReadError> yea but I need a daughter card
[19:00:56] <ReadError> for the other steppers
[19:01:05] <neverbuya_subaru> oh its a servo + stepper system
[19:01:06] <neverbuya_subaru> :P
[19:01:10] <ReadError> ya
[19:01:15] <neverbuya_subaru> why do you need a daughter card though
[19:01:17] <ReadError> important bits are servo
[19:01:22] <neverbuya_subaru> you have 6 step/dir
[19:01:24] <neverbuya_subaru> on the 7i76e
[19:01:25] <ReadError> because im 1 stepper over my limit
[19:01:29] <ReadError> it says 5 ?
[19:01:32] <neverbuya_subaru> is it?
[19:01:34] <neverbuya_subaru> lemme check :P
[19:01:35] <ReadError> or thought it did anyways
[19:01:43] <ReadError> tellin you, this mesa stuff is super confusing
[19:01:48] <neverbuya_subaru> damn it its 5 :P
[19:02:14] <neverbuya_subaru> its confusing inthe beginning
[19:02:17] <neverbuya_subaru> but when you figure it out
[19:02:21] <neverbuya_subaru> you slap yourself cause its easy :P
[19:03:42] <ReadError> cool thanks for the help, hopefully those 2 will get me going nicely
[19:03:43] <neverbuya_subaru> so basically youre talking about expansion card
[19:03:45] <neverbuya_subaru> for 7i76e.
[19:03:48] <ReadError> yea
[19:03:50] <neverbuya_subaru> im sure there is a cheaper alternative
[19:03:53] <neverbuya_subaru> than the 7i76
[19:03:56] <ReadError> i thas the 2x 26 pin
[19:03:57] <neverbuya_subaru> cause you only need 1 more
[19:04:10] <ReadError> http://store.mesanet.com/index.php?route=product/product&path=83_87&product_id=121
[19:04:11] <neverbuya_subaru> and like tom was saying
[19:04:17] <neverbuya_subaru> youre going to need a custom config file
[19:04:17] <ReadError> theres that
[19:04:24] <neverbuya_subaru> to let it know that you got an expansion card
[19:04:31] <ReadError> but i plan on needing more generic GPIO later
[19:04:36] <ReadError> so I kinda wanted to over allocate
[19:04:37] <neverbuya_subaru> they dont make something thqat uses smart serial?
[19:04:58] <neverbuya_subaru> One RS-422 interface is provided for I/O expansion via a serial I/O daughtercard.
[19:04:59] <neverbuya_subaru> nm
[19:05:35] <ReadError> i may put a servo on my Z axis too
[19:05:42] <ReadError> so figured i should keep some stuff open for that
[19:05:51] <neverbuya_subaru> what are you using for the "parent" card
[19:06:10] <ReadError> 7i76e
[19:06:14] <neverbuya_subaru> no
[19:06:17] <neverbuya_subaru> i mean like 5i25 or 6i25
[19:06:32] <ReadError> hmm i was under the impression the 'e' one was standalone
[19:06:45] <ReadError> and the 7i76 needed a parent
[19:07:15] <neverbuya_subaru> i dont know =/
[19:07:22] <neverbuya_subaru> usually with 7i77
[19:07:25] <neverbuya_subaru> you use a 5i25 or 6i25
[19:07:38] <neverbuya_subaru> but it has no ethernet interfgace
[19:08:21] <ReadError> The 7I76E ia a remote FPGA card with Ethernet interface designed for interfacing up to 5 Axis of step &dir step motor or servo motor drives and also provides a spindle encoder interface, isolated analog spindle speed control and 48 isolated I/O points for general purpose field I/O use.
[19:08:29] <ReadError> it sounds like its standalone anyways
[19:08:43] <ReadError> or has its own FPGA
[19:08:52] <neverbuya_subaru> ya
[19:09:00] <neverbuya_subaru> how do you communicate with it from the comp?
[19:09:03] <neverbuya_subaru> using your ethernet card?
[19:09:03] <neverbuya_subaru> :p
[19:09:14] <neverbuya_subaru> thats cool
[19:09:18] <ReadError> yea
[19:09:22] <neverbuya_subaru> cause that means
[19:09:27] <neverbuya_subaru> you could technically use a rasp pi 2
[19:09:32] <neverbuya_subaru> and use the 7i76e with it
[19:09:39] <neverbuya_subaru> i always thought 7i76e was 7i76 w/ encoder
[19:09:40] <ReadError> i was thinking about using a BBB and going full MAKER
[19:09:41] <neverbuya_subaru> but i am wrong
[19:09:42] <ReadError> ;p
[19:09:48] <neverbuya_subaru> thats a cool project :)
[19:09:49] <ReadError> but i have this atom eeepc laying around
[19:10:15] <ReadError> runs a 6000 servo thread
[19:10:42] <neverbuya_subaru> i keep reading this thing
[19:10:49] <neverbuya_subaru> about "analog is better when closing the loop in the control"
[19:11:00] <neverbuya_subaru> "and step/dir if loop is closed in the drive"
[19:11:05] <neverbuya_subaru> they don't mention what loop it is
[19:11:08] <neverbuya_subaru> and why.
[19:11:08] <neverbuya_subaru> :p
[19:11:17] <ReadError> hmm so analog AND step/dir?
[19:11:36] <ReadError> I cant think of any reason why analog would be better offhand....
[19:13:51] <neverbuya_subaru> me either
[19:14:28] <neverbuya_subaru> cost ?
[19:14:28] <neverbuya_subaru> :p
[19:16:18] <ReadError> seems more complicated http://www.theamphour.com/wp-content/uploads/2011/03/bob_widlar_digital1.jpg
[19:16:28] <neverbuya_subaru> rofl
[19:16:47] <neverbuya_subaru> to me digital seems better
[19:16:55] <neverbuya_subaru> cause you could configure them to run independentaly
[19:17:00] <neverbuya_subaru> and use some sort of fieldbus wiring
[19:17:07] <neverbuya_subaru> the wiring would be possibly shorter
[19:17:13] <ReadError> i was pretty impressed spinning these things around on the bench
[19:17:14] <neverbuya_subaru> and easier to route
[19:17:15] <ReadError> so smooth

[22:02:44] <JT-Shop> big bikes
[22:03:16] <neverbuya_subaru> man this movie
[22:03:20] <neverbuya_subaru> "play the big short"
[22:03:23] <neverbuya_subaru> really scary.
[22:03:31] <neverbuya_subaru> financial system is really that screwed
[22:03:40] <Tom_itx> worse
[22:04:17] <neverbuya_subaru> the movie does a good job of explaining the crash of 2008
[22:04:26] <neverbuya_subaru> and the people that knew it was coming 2 years before it happened
[22:04:27] <neverbuya_subaru> and how they knew
[22:05:04] <neverbuya_subaru> and how CDOs have been replaced by "bespoke tranche opportunity" (reason for collapse)
[22:05:52] <jdh> it obviously works fine. they are still rich.
[22:05:56] <neverbuya_subaru> yep
[22:05:59] <neverbuya_subaru> only one guy got arrested
[22:06:00] <neverbuya_subaru> apparently
[22:06:05] <neverbuya_subaru> so many commited fraud
[22:06:08] <neverbuya_subaru> the gov is involved in it too
[22:06:20] <neverbuya_subaru> in the end 5 trillion dollars were lost from pension 401k savings etc
[22:06:27] <neverbuya_subaru> 5 trillion!
[22:06:36] <Tom_itx> as long as there is one fall guy everyone else is ok
[22:07:05] <neverbuya_subaru> i find this interesting
[22:07:14] <neverbuya_subaru> the guy know analyzed the data and caught the bubble 2 years before it happened
[22:07:23] <neverbuya_subaru> is now investing in only one thing. water
[22:07:30] <neverbuya_subaru> :p
[22:07:49] <neverbuya_subaru> he btw made 289 billion dollars from the collapse :p
[22:09:13] <neverbuya_subaru> i think its 2.89
[22:09:15] <neverbuya_subaru> whoops :)
[22:09:24] <neverbuya_subaru> Though he suffered an investor revolt before his predictions came true, Burry earned a personal profit of $100 million and a profit for his remaining investors of more than $700 million.[3] Scion Capital ultimately recorded returns of 489.34 percent (net of fees and expenses) between its November 1, 2000 inception and June 2008. The S&P 500 returned just over two percent over the same period.[3]
