[00:00:35] <Jymmm> archivist: Copper and wood ring
https://www.youtube.com/watch?v=7hkKErj7pqI
[01:52:51] <MrSunshine> hmm bullnose cutters for wood, anyone know of a source for that? =)
[01:53:22] <MrSunshine> with tht evacuum table it could be very usefull for 3d angled faces on sheet =)
[01:54:27] <MrSunshine> and prefereable downcut ;P
[01:54:28] <MrSunshine> haha
[01:58:31] <Connor> Why downcut ?
[02:04:34] <MrSunshine> to push the material against the table to minimize the risk for it comming lose =)
[02:07:35] <toastydeath> a reverse flute bullnose router bit seems like a fairly specialty item
[02:10:58] <MrSunshine> yeah i guess it is :(
[02:11:48] <MrSunshine> with it i could get the 3d profiling capabilities of a ballnose and have a heavy cutter and a small corner radius to get good finnish
[02:12:41] <MrSunshine> but looking at how hard a sheet sits on the vacuum table .. lifting it with a profiling cut like that i guess is nothing to be bothered about :P
[02:13:03] <MrSunshine> as when doing 3d contours i will have a small stepdown .. so shallow cuts =)
[02:20:19] <renesis> mrsunshine: fuck i dont remember the name of the place exexexexjob got its tools from
[02:26:43] <renesis> hmm yeah i cant find something that rings a bell, im pretty sure they had those
[02:27:07] <renesis> they had ball downcut
[03:13:37] <Deejay> moin
[05:23:06] <oshw> hello
[05:23:17] <oshw> how i can read linuxcnc params from python?
[05:25:54] <micges> oshw: what params?
[05:27:37] <oshw> 5601, x probed position
[05:29:02] <oshw> i'm trying to modify probe_screen, and just adding self.params[5601] seems not ok
[05:29:33] <micges> sorry, don't know that part of lcnc
[05:39:37] <archivist> 5601? Parameter #5601 contains the value of the toolchanger-reason pin.
[05:40:06] <archivist> one would connect that pin to something the gui can read
[05:44:32] <archivist> I see a mention here but that states '# this is relevant only when using iocontrol-v2.'
https://github.com/araisrobo/linuxcnc/blob/master/configs/araisrobo/python-stdglue/stdglue.py
[05:50:39] <oshw> sorry 5061 variabile, X Probed result. But anyway i dont understand how stdglue.py reads those variabiles
[05:52:45] <oshw> self.params[5061] returns AttributeError: instance has no attribute params
[05:54:09] <archivist> I think that comment in that other code may be a clue, to get it readable
[06:15:25] <Jymmm> $1000 for a single split piece of firewood?!?!?!
http://www.cbc.ca/radio/thisisthat/canadian-entrepreneur-finds-international-success-selling-firewood-for-1000-per-bundle-1.3219747
[06:16:21] <XXCoder> dang
[06:16:22] <XXCoder> cheap
[06:16:57] <Jymmm> I can't tell if that is a joke or not. It's gotta be, right?
[06:17:03] <XXCoder> I bet they just go to those shops and buy bundles
[06:17:11] <XXCoder> honestly dunno
[06:17:24] <XXCoder> I mean, there is worse things for more money
[06:17:25] <Jymmm> It loks like a joke
[06:17:42] <Jymmm> Like a SNL skit
[06:17:53] <XXCoder> you heard of poe's law? this is similiar
[06:18:06] <XXCoder> there is weirder things so its hard to be sure if its fake or not
[06:18:21] <Jymmm> never heard f poes law
[06:18:35] <XXCoder> history of poe's law is funny
[06:18:37] <Jymmm> does it have a raven?
[06:19:00] <XXCoder> Poe just made a comment and it turned out to be a good law lol

[06:22:06] <_methods> artisanal firewood lol
[06:22:56] <_methods> is that where you chop down the tree while drink a craft beer with a chisel that you made from ore you mined yourself and a hand crafted artisanal handle?
[06:23:11] <XXCoder> _methods: grown by yourself
[06:23:16] <_methods> ^^
[06:23:26] <_methods> i raised that tree from an acorn
[06:23:37] <_methods> fed it only the finest waters
[06:23:38] <XXCoder> yep lol
[06:23:45] <XXCoder> evian water lol
[06:23:57] <XXCoder> or tap water, triple filtered
[06:24:02] <_methods> playin it mumford and sons 24/7

[06:24:34] <XXCoder> (it dont have to make sense ya know!)
[06:24:57] <Jymmm> Hey, they do it to Kobi Cows
[06:25:01] <Jymmm> and beer too
[06:25:15] <XXCoder> theres shit coffee so yeah anything goes

[06:27:51] <_methods> we got one cow man, let's make this fucker taste good
[06:28:11] <XXCoder> I dont like the force feed part

[06:29:28] <XXCoder> enjoy
[06:31:19] <XXCoder> literal poop for sale. squirrel poop.
[06:32:00] <Jymmm> thats called fertilizer
[06:32:09] <XXCoder> its used as herbs
[06:32:11] <XXCoder> so.. yeah
[06:32:13] <XXCoder> :P
[06:32:17] <XXCoder> bottoms up
[06:34:48] <Jymmm> Think about it, who would ever pay $6 for a cup of coffee...
[06:35:30] <XXCoder> plenty do
[06:35:31] <malcom2073_> Apparently quite a lot of people, if starbucks stock shows anything
[06:35:35] <XXCoder> just look at starbuck
[06:35:57] <Jymmm> malcom2073_: </sarcasim>
[06:36:47] <Jymmm> Or pay $32 for a bowl of garden bugs (snails)
[06:48:59] <gonzo_> how about buying bee sick
[06:49:27] <XXCoder> aka honey?
[06:50:15] <malcom2073_> Damn those happy people and their being happy with food.
[06:50:48] <Jymmm> gonzo_: (vomit)
[06:51:26] <gonzo_> yep, that's the stuff
[06:53:12] <gonzo_> cow lactation, buts of cut up dead animal, things that grow in dirt, actual dirt that has had animal poo put in it.....
[06:53:31] <XXCoder> LOL "Finger Stylus for Smartphone"
[06:53:34] <gonzo_> bits of anomal (unless it's a good steak, then it probabl;y is buts!)
[06:53:41] <XXCoder> HMM what about... finger? :P
[06:53:41] <Jymmm> http://www.amazon.com/gp/product/B00CATFKFE/
[06:54:22] <XXCoder> you need to sell 896 pencils to equal that price
[06:54:30] * Jymmm searches for testing centers that require #2 pencils... PROFIT!!!
[06:54:37] <XXCoder> assuming you got lots pencils "fell off back o0f truck".
[06:54:45] <malcom2073_> + the cost of pencils
[06:55:19] <Jymmm> gross for $16 (11¢/ea)
[06:55:30] <malcom2073_> "Coin Mechanism set for .25; Can notify us if would like .50 or .75"
[06:55:34] <malcom2073_> Soundsl ike .50 would be a better bet
[06:56:02] <XXCoder> at perfectly right spot, sell pencils at $100 each
[06:56:17] <XXCoder> just state it was made by hamsters trained to chew and make pencils
[06:56:26] <gonzo_> you need your finger stylus for:

[06:57:21] <XXCoder> lol nophone
[06:58:25] <XXCoder> lol 100 plastic pennies for $9.21. I'd rather get one dollar worth of pennies. :P
[06:59:34] <Jymmm> http://www.amazon.com/gp/product/B014RD021C/
[07:00:01] <XXCoder> Jymmm: that + solar energy = MAYBE actual break even. maybe.
[07:01:59] <Jymmm> XXCoder: There was this homeless guy that lived in the hill, he would actually tap into the high voltage lines to power his laptop
[07:03:26] <malcom2073_> You'd be better off selling the solar energy back to the power company
[07:03:34] <XXCoder> yeah
[07:05:41] <malcom2073_> Ohhh that's cute. The bitcoin mining is secondary
[07:05:55] <XXCoder> I'm still waiting for my CHiP
[07:06:03] <malcom2073_> Hah did that ever happen?
[07:06:30] <XXCoder> my brother should be getting his soon
[07:07:16] <malcom2073_> Did they ever figure out why it was being so heavily subsidized?
[07:08:01] <XXCoder> nipple for your nipples
[07:08:08] <XXCoder> plastic nipples to hide your nipples
[07:08:28] <XXCoder> so, do you need another plastic nipples to hide your plastic nipples and so on? :P
[07:08:34] <XXCoder> man thats one weird product
[07:09:44] <malcom2073_> I'm more interested in the VoCore
[07:15:43] <XXCoder> toyata just unveiled fuel cell car
[07:16:13] <MattyMatt> rotary fuel cell? :)
[07:17:15] <MattyMatt> ^call your V8 that
[07:17:40] <XXCoder> :P
[07:20:33] <Sync> I like that mazda sticks with the rotary
[07:21:01] <MattyMatt> rover never stuck with theirs. they did a gas turbine saloon
[07:21:19] <MattyMatt> only thing wrong with it was the noise
[07:21:46] <XXCoder> VW is trying fuel cell now too
[07:21:57] <MattyMatt> is it bugatti doing one atm? gas turbine hybrid
[07:22:04] <XXCoder> try salvage their rep
[07:24:07] <MattyMatt> http://www.popularmechanics.com/cars/hybrid-electric/a6153/jaguar-hybrid-micro-turbine-engineering/ ah jagwar
[07:28:09] <MattyMatt> 80krpm to achieve 20% efficiency at 180hp. sounds like a good spindle
[07:29:56] <MattyMatt> for friction spot drilling
[07:38:52] <Tom_itx> Jymmm, they would place the wood on the mantle instead of in the fireplace...
[09:51:51] <ssi> morn
[09:52:01] <malcom2073_> Morning
[10:10:14] <Topy44> hi
[10:10:30] <Topy44> since they are a lot more common in the US and there seem to be a lot of US people here:
[10:10:44] <Topy44> i am considering getting a ryobi cordless drill
[10:11:08] <Topy44> p214 cordless hammer drill to be specific (its actually not available here, i'd import it)
[10:11:17] <Topy44> the alternatives are makita or panasonic, but their low end models
[10:11:44] <Topy44> any opinions? reviews of the p214 seem very favourable and i like their large range of compatible products for their one+ battery system
[10:14:58] <Sync> why don't you get a makita one, that you don't need to import?
[10:15:09] <Sync> in the end ryobi is just TTI
[10:59:55] <anomynous> https://www.youtube.com/watch?v=1JcvCZFG0L0 pretty big "work envelope" ;D
[11:00:32] <anomynous> same in steel?
[11:03:25] <ssi> 8 axis?
[11:03:38] <ssi> oh XYZUVW and two rotaries?
[11:03:45] <ssi> hm no never mind it's an arm
[11:03:57] <ssi> six axis arm on a rail I guess
[11:19:23] <CaptHindsight> if it was cutting steel the feed rate would be 100x lower
[11:20:06] <Contract_Pilot> Sup. got me a mesa 5i25 and 7i76 and 7i77 on the way whoo hoo...
[11:20:18] <Erant> Contract_Pilot: When did you order?
[11:20:29] <ssi> sweet
[11:20:30] <Contract_Pilot> Private deal.
[11:20:41] <Erant> Ah, nice.
[11:21:05] <Contract_Pilot> Could have had 4 weeks ago if the Notification system worked!
[11:21:06] <Erant> Still waiting on my 5i25 + 7i78 :(
[11:21:53] <Contract_Pilot> Prob will not use the 7i77 but good to have arround if i wanted to do somthing with servo's
[11:22:59] <Contract_Pilot> Been preping for the gun show what a chore.
[11:24:00] <malcom2073_> Contract_Pilot: Did you order newegg *and* walmart motors?
[11:24:00] <malcom2073_> Or just walmart?
[11:24:08] <Contract_Pilot> I did both
[11:24:16] <malcom2073_> You got both too?
[11:24:25] <malcom2073_> My newegg motors are on week two of 3 day shipping heh
[11:24:27] <Contract_Pilot> Every subsequant order cancled.
[11:24:33] <gonzo_> anyone here at the mo, who's played with the 7i90
[11:24:41] <ssi> my order wasn't canceled, he sent me a new tracking number, but there's been no movement on it
[11:24:48] <ssi> I opened a case with newegg yesterday
[11:24:48] <malcom2073_> ssi: That's what I'm seeing
[11:25:04] <malcom2073_> I tried to open a case, they said it has to be more than 30 days since ordering, and less than 60 to open a case.
[11:25:08] <Contract_Pilot> http://www.stevenrhine.com/wp-content/uploads/2015/10/Stepper-Driver-PSU-Lot-1024x576.jpg
[11:25:27] <ssi> Contract_Pilot: holy cow
[11:25:37] <ssi> stocking up for the apocalypse?
[11:25:37] <Contract_Pilot> All my stff arrived.
[11:25:48] <ssi> Contract_Pilot is the reason nobody else is getting any ;)
[11:25:55] <malcom2073_> lol yeah
[11:26:09] <ssi> what's in the cardboard boxes, power supplies?
[11:26:20] <Contract_Pilot> Yep.
[11:27:11] <CaptHindsight> I'll have to remember that. I'm sorry we don't handle complaints until days 30-60. Please call or write back during this window.
[11:27:20] <Contract_Pilot> Top banner for gun show this weekend.
http://www.stevenrhine.com/wp-content/uploads/2015/10/AK-Banner-Top.jpg
[11:28:12] <Contract_Pilot> So looks like i will be Setting up PathPilot next week on the lathe! Been a long long wait.
[11:29:40] <CaptHindsight> Contract_Pilot: what's the attraction or perceived "betterness" to PathPilot over Linuxcnc?
[11:30:39] <Contract_Pilot> GUI
[11:38:50] <Contract_Pilot> Taxing a 48V 10A PSU hahaha!!

[11:40:46] <CaptHindsight> http://www.tormach.com/blog/wp-content/uploads/2015/04/Fig-x.x-First-part.png
[11:41:12] <CaptHindsight> Contract_Pilot: this GUI ^^^ ?
[11:43:49] <Contract_Pilot> Yep the user interface.
[11:46:54] <CaptHindsight> Contract_Pilot: is there source for their GUI so you can modify it?
[11:49:51] <CaptHindsight> Contract_Pilot: did you ever find a home to host their source or ISO?
[11:53:52] <Jymmm> 50GB Free...
https://mega.nz/
[11:55:07] <CaptHindsight> heh that site of kitten molesters?
[12:05:44] <Jymmm> I know nothing of that, just free be free =)
[12:25:52] <Erant> Huh. So PathPilot runs on top of LinuxCNC?
[12:26:43] <ssi> pathpilot is a variant of linuxcnc
[12:26:56] <archivist> something like that, also uses a bit of machinekit (also a fork of linuxcnc)
[12:27:43] <Connor> PP is LinuxCNC with a different GUI vs Axis or gmoccapy
[12:27:57] <Erant> Ah. So closed source then.
[12:28:02] <ssi> not exactly
[12:28:38] <JT-Shop> hmm it's a Fugi with ball screws and linear rails
[12:42:04] <Erant> Hmm. So my mill is the tiniest thing (because it has to live in a shop the size of a minivan) and it has a 250W brushless DC motor. According to LittleMachineShop, there's no gearing between it and the spindle. From what it looks like it's just a standard Nema34 servo.
[12:42:20] <Erant> What parts would I be stressing if I replaced it with a 500W servo?
[12:45:50] <Tom_itx> probably the whole thing if it was designed for 250w
[12:46:47] <Tom_itx> you would be tempted to cut more than the rest of it could handle then
[13:11:08] <JT-Shop> now to figure out if it works
[13:17:59] <Erant> Tom_itx: Fair enough. It's not like I _need_ more power. I was just curious
[13:18:54] <Erant> Which makes me curious about those weenie CNC routers I saw on eBay when I was shopping around with like 800W or 1.5kW VFD spindles
[13:29:24] <archivist> people with weenie routers should measure the flex of the machine
[13:41:20] <WZL> hello all,
[13:42:17] <WZL> do you have any recommendation for a touchscreen??
[13:43:06] <Loetmichel> Erant: i have a CNC6040 ... with the 800W VFD spindle
[13:43:40] <cradek> get a usb-connected ELO, and google the model number and see if it works plug-and-play with linux before you buy it
[13:43:46] <Loetmichel> ... that starts flexing in the gantry as soon as you go above maybe 200W input to the spindle from cutting aluminium alone...
[13:43:57] <Loetmichel> so no need to get a bigger motor at all ;)
[13:44:32] <Loetmichel> WZL: i am building 12" tft boxes at the company atm with 12" resistive touchsreens
[13:45:01] <Loetmichel> these would be optimal for a CNC machine i thing. beacuse you can operate them with gloves
[13:45:15] <Loetmichel> but they scratch easily because they are plastic at the front
[13:45:23] <Loetmichel> so its your choice
[13:45:40] <Loetmichel> i can get the specs from the company tomorrow if you whish.
[13:45:55] <WZL> there is any problem with dirt and coolant with the touchscreens? I have a vw car with a resistive and works ok but i think that a single chip can scratch it
[13:46:55] <cradek> there are a lot of different touchscreen technologies
[13:47:24] <cradek> glass is good for scratch resistance
[13:47:42] <cradek> some will respond to a coolant fingerprint (wet spot) and others won't
[13:47:43] <WZL> loetmichel: I´m from Argentina, locally i can find elo (i think that is capacitive technology) and a saw technology from a chinese brand
[13:48:05] <cradek> ELO has lots of different technologies
[13:48:37] <cradek> I think my mill has an ELO SAW model
[13:49:49] <WZL> what is the consensus? It worth spend in a touchscreen or I'm better with a panel keyboard and touchpad
[13:49:56] <WZL> is about the same price
[13:50:06] <cradek> it depends
[13:50:12] <malcom2073_> I don't see that much use to a touchscreen unless you're gonna write/use a touch friendly UI
[13:50:15] <aventtini6> hi zee is on guys?
[13:50:16] <malcom2073_> of which, Axis is definently not
[13:50:16] <cradek> I love using Touchy on my mill (it has no mouse or keyboard)
[13:50:30] <aventtini6> what model is his mikron?
[13:50:43] <cradek> AXIS is unusable without a keyboard
[13:50:43] <ssi> I've always wanted to get to where I could use touchy or something similar
[13:50:48] <ssi> I hate having to use a mouse on a cnc machine
[13:50:56] <malcom2073_> I want to use just the keyboard, no mouse or touch heh
[13:51:05] <cradek> AXIS is quite good for keyboard only
[13:51:12] <malcom2073_> I've not yet learned enough of the shortcuts heh
[13:51:12] <ssi> honestly touch-screen plus a nice button panel is what I'd like to have
[13:51:14] <JT-Shop> I use Touchy on my mill and it has a mouse and keyboard... ain't figured out how to enter my password to update without a keyboard
[13:51:18] * Loetmichel simply uses a silicone rubber keyboard
[13:51:25] <cradek> touchy is quite good for touchscreen only
[13:51:33] <malcom2073_> Loetmichel: That's what I have on mine, very nice for oil/chip resistance
[13:51:45] <ssi> I've used the silicone ones, but they're miserable to actually type on
[13:51:47] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12569
[13:51:54] <cradek> JT-Shop: I just ssh from another machine if I need to do that kind of thing
[13:51:56] <malcom2073_> Mine is a silicon cover over a normal keyboard
[13:51:59] <Loetmichel> it even resists red hot chips
[13:52:58] <bz> how bad of an idea is it to use an end mill on sheet metal?
[13:53:18] <ssi> bz: it's fine as long as the sheet metal is very securely clamped
[13:53:21] <ssi> which can be tough to do
[13:53:25] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14040&g2_imageViewsIndex=1 <- better pic
[13:53:39] <JT-Shop> I need to learn how to ssh
[13:53:42] <malcom2073_> I have one of these:
https://upload.wikimedia.org/wikipedia/commons/thumb/1/1f/Medigenic_Medical_Keyboard.JPG/1280px-Medigenic_Medical_Keyboard.JPG
[13:53:55] <Loetmichel> bz: if you use double sided tape or a vacuum table: i do it all the time
[13:53:56] <WZL> last week I tested gmoccapy with my surface tablet and looking very good but in the workshop may be a different story.
[13:54:08] <Loetmichel> i wouldnt do it on only "side clapmed" sheets tho
[13:54:48] <Loetmichel> i dont use sssh
[13:55:06] <WZL> something like this
http://www.ruggedized-keyboard.com/photo/ruggedized-keyboard/editor/20150204153333_23050.jpg ???
[13:55:06] <Loetmichel> but i sometimes use VNC and VLC for the machines Camera
[13:55:27] <malcom2073_> WZL: That doens't look sealed

[13:56:32] <malcom2073_> JT-Shop: What'd ya buy?
[13:56:56] <JT-Shop> $0
[13:56:56] <WZL> malcom2073: it says IP68
[13:57:05] <malcom2073_> What'd you aquire? :P
[13:57:25] <JT-Shop> optical comparator
[13:57:26] <malcom2073_> WZL: I'm not familiar with that spec, if it covers what you want to do ,then it'd be fine yeah?
[13:57:30] <JT-Shop> but the light don't work
[13:57:34] <malcom2073_> Those are some serious linear rails on that thing
[13:57:57] <JT-Shop> might make something else out of it and toss the upper
[13:58:02] <malcom2073_> Yeah
[13:59:40] <JT-Shop> has a nice 20" x 20" table
[14:01:38] <JT-Shop> has a nice DRO and scales too
[14:03:23] <bz> ssi, Loetmichel: i'm actually more concerned about the tool tip
[14:03:41] <Loetmichel> bz: why?
[14:03:45] <bz> should i cut at a lower rpm and feedrate?
[14:03:58] <Loetmichel> what kind of tip is it?
[14:04:05] <ssi> the only thing that makes cutting sheet metal different than cutting barstock is the rigidity of the workpiece
[14:04:09] <Loetmichel> "cutting over middle" or not?
[14:04:17] <ssi> so, with adequate clamping, just use the regular numbers for the material
[14:04:24] <bz> ssi: that makes sense
[14:04:34] <ssi> I'm guessing what you really mean is you're concerned about slotting operations
[14:04:43] <ssi> just choose an endmill that's designed to slot cut well
[14:04:45] <Loetmichel> thats what i meant with "tape or vaccum underneath"
[14:04:59] <Loetmichel> thin sheet metal tends to lift of the work table otherwise
[14:05:05] <bz> well i have it screwed onto a sacrifical block of wood
[14:05:06] <Loetmichel> if only clamped at the outside
[14:05:19] <bz> and then the whole thing gripped inside a vise
[14:05:32] <ssi> I'd back up your screws with some double sided tape, unless your screws are pretty frequent and close together
[14:05:39] <ssi> the metal is going to chatter and flex like crazy otherwise
[14:06:25] <archivist> double sided tape is a bugger to get off and helps bend very thin sheet
[14:06:56] <ssi> CA glue on an aluminum block works too
[14:06:59] <ssi> break the CA bond with heat
[14:07:01] <archivist> be prepared to flatten (roll it)
[14:09:07] <Loetmichel> ssi: no heat neceessary
[14:09:21] <Loetmichel> just tap the finsied pice with a rubber hammer from the side
[14:09:30] <Loetmichel> CA glue is brittle
[14:10:13] <Loetmichel> ssi: CA glue works surprisingly well
[14:10:17] <Loetmichel> even on bigger parts
[14:10:20] <FAalbers> Does linuxcnc work with the UC100 ?
[14:10:20] <ssi> yeah
[14:10:27] <Loetmichel> s/bigger/thicker
[14:10:41] <ssi> and the more surface area glued, the better
[14:11:03] <archivist> FAalbers, no it wont
[14:11:08] <FAalbers> OK
[14:11:37] <archivist> USB is a fail for realtime work
[14:13:20] <Loetmichel> https://www.youtube.com/watch?v=9u_ChO1AKYY <- glued to the work table with CA ;)
[14:14:05] <FAalbers> archivist, even on a fast computer ?
[14:14:21] <Jymmm> Loetmichel: what camera and how did you use vlc to get a love feed?
[14:14:26] <Jymmm> live*
[14:14:53] <archivist> FAalbers, not any way, linuxcnc does not work with buffered motion controllers
[14:15:23] <Loetmichel> Jymmm:
http://www.ebay.de/itm/like/271711337307?ul_noapp=true&chn=ps&lpid=106
[14:15:25] <archivist> FAalbers, makes no sense linuxcnc can control 9 axes on a pc
[14:15:25] <Loetmichel> one of these
[14:15:49] <Jymmm> Loetmichel: Ah, and VLC?
[14:15:53] <FAalbers> archivist, I was also thinking just using Mach3 on Windows
[14:16:07] <Loetmichel> and yes, on the LlinuxCNC box vlc as a server to do a htp strean and on the win box in the office as a client
[14:16:17] <FAalbers> archivist, And I only need 3 axis
[14:16:18] <Jymmm> Loetmichel: lol
[14:16:48] <FAalbers> archivist, Linuxcnc was just one of the possible systems
[14:17:11] <Loetmichel> and it works surpsisingly well
[14:17:17] <ReadError> mach3 gave my cat feline AIDS ;(
[14:17:18] <Jymmm> Loetmichel: has light?
[14:17:29] <archivist> FAalbers, you are in the wrong place for mach support as it cannot do many things that linuxcnc can on a mill
[14:17:29] <Loetmichel> the linuxCNC box is just a sempron 3000
[14:17:49] <Loetmichel> still it can cope with recoding 640*480 video while milling ;)
[14:17:56] <Loetmichel> Jymmm: the cam? yes
[14:18:03] <Loetmichel> 4 or six white leds
[14:18:25] <WZL> we are using mjpg streamer with a logitech c270 wevcam in a mobile robot and works very good
[14:21:06] <Loetmichel> Jymmm: actually you can see the cam in the second part of the video
[14:21:29] <Loetmichel> the little black pin protunding from the vacuum encloure around the spindle
[14:28:05] <FAalbers> archivist, I have not done enough research yet , I just want to get it to start do something while not buying stuff that will not be OK later on . Thank you for your feedback, I will just dig into it some more :) I really appreciate
[14:29:19] <archivist> FAalbers, also upgrades to later version give you more facilities in linuxcnc, not less
[14:29:59] <archivist> you may want spindle linked motion too, tapping etc
[14:30:03] <FAalbers> Thanks archivist
[14:30:54] <ssi> lol an aerostat came unmoored
[14:31:00] <ssi> it's roaming around pennsylvania terrorizing the locals
[14:37:39] <malcom2073_> Sweet, where?
[14:37:40] <malcom2073_> :-D
[14:38:02] <ssi> I dunno exactly, watch CNN they're reporting on it live right now
[14:38:10] <ssi> it's causing power outages they're saying
[14:38:11] <malcom2073_> Meh I don't get CNN
[14:38:17] <ssi> what do you mean you don't get cnn
[14:38:20] <ssi> everyone gets cnn
[14:38:27] <malcom2073_> I don't have live tv?
[14:38:34] <ssi> you're on the internet, just type those seven magic chars into the web browser of your choice
[14:38:38] <ssi> cnn.com
[14:38:49] <malcom2073_> Meh
[14:38:50] <malcom2073_> But ok:P
[14:38:58] <ssi> and my army of magical internet monkeys will make sure that fresh news is spouted directly into your home with only a teeny twinge of media bias
[14:39:28] <archivist> no honest person has bias!
[14:39:31] <malcom2073_> Teeny twinge? Can we go for Eensy Weensy twinge?
[14:39:38] <malcom2073_> I'd watch it if it was only eensy weensy
[14:39:45] <ssi> sorry, I'm not in charge of the bias department, just the magical internet monkeys department
[14:39:48] <malcom2073_> archivist: That's biased.
[14:40:08] <archivist> neva!
[14:40:14] <malcom2073_> Oh, so you're dishonest
[14:40:18] <malcom2073_> in which case, I believe you
[14:41:03] <malcom2073_> I'm gonna go finish turning my pulley adapter so I can get my millback up and running
[14:41:36] <ssi> millback?!
[14:42:02] <malcom2073_> Yeah, it's like a mill, except with a spacebar failure stuck in for good measure
[14:42:09] <ssi> awesome
[14:54:33] <Erant> PCW: Ping?
[14:58:45] <malcom2073_> Oh fun, thin sheen of water over my lathe and mill surfaces, even with oil on them
[14:59:52] <SpeedEvil> condensation?
[15:00:40] <malcom2073_> yeah, it got damn cold last night, and today is pretty warm and humid
[15:01:03] <SpeedEvil> a few 10W heaters bolted on helps lots
[15:01:14] <malcom2073_> Really?
[15:01:17] <malcom2073_> hmm
[15:01:44] <SpeedEvil> you only need to get it so it's above the dew point.
[15:01:52] <Jymmm> malcom2073_: is this a garden shed or what?
[15:01:54] <malcom2073_> Or rather, keep it above the dew point
[15:01:56] <malcom2073_> Jymmm: No, my garage
[15:02:02] <malcom2073_> Uninsulated, concrete block box
[15:02:05] <Jymmm> malcom2073_: 40W lightbolb?
[15:02:27] <malcom2073_> So it got down to just below freezing last night, and it's probably 70 and 90% humidity right now
[15:02:40] <SpeedEvil> http://www.ebay.co.uk/itm/Screw-Tabs-5-330-Ohm-10W-Aluminum-Wire-Wound-Resistor-/291252622092?hash=item43d002530c:g:uYsAAOSwI-BWF3nm I meant
[15:02:51] <Jymmm> malcom2073_: Thats what we used for a hen house, a red 40W lightbulb
[15:03:42] <malcom2073_> I can't keep the air warm, it takes about 3-4kw to get a 10C temperature rise
[15:04:03] <malcom2073_> Would a 10W heater bolted to the metal base raise the temp of it appreciably?
[15:04:09] <SpeedEvil> ~10 or so of those, bolted over the various components, running at 3-4W each
[15:04:44] <CaptHindsight> and put a cover over it as well
[15:05:04] <malcom2073_> This is really only going to be a problem for a few months in fall, and a few in spring
[15:05:14] <malcom2073_> But yeah, if the heaters would help....
[15:05:16] <Jymmm> malcom2073_: tarp and 40W lightulb
[15:05:17] <CaptHindsight> electric blanket
[15:05:19] <malcom2073_> Wonder how much that would cost
[15:05:26] <malcom2073_> calculator time!
[15:05:59] <Jymmm> If you have a heavy tarp/blankets to insulate it, would take very little heat at all
[15:06:03] <malcom2073_> $10 a month or so, assuming 100W total energy usage.
[15:06:16] <malcom2073_> And constantly on
[15:06:27] <SpeedEvil> and yes
[15:06:33] <SpeedEvil> electric blanket is awesome
[15:06:53] <CaptHindsight> can you flood the garage with nitrogen?
[15:06:57] <SpeedEvil> you can be perfectly comfy in ~0C ambient with ~60W or so of heat and a relatively thin blanket
[15:07:02] <Jymmm> but put LOTS of blankets/insulation over it
[15:07:18] <malcom2073_> That's annoying to have to cover it after every use heh
[15:07:20] <SpeedEvil> CaptHindsight: you probably want fluorine, to provide a reducing atmosphere.
[15:07:38] <malcom2073_> CaptHindsight: if the garage was airtight, this wouldn't be as much of an issue :P
[15:07:48] <CaptHindsight> or argon
[15:07:54] <malcom2073_> I could just control the humidity then directly, ignoring the temp, bring it to 0
[15:07:56] <Jymmm> HYDROGEN!
[15:08:03] <malcom2073_> Worked for zee germans
[15:08:09] <SpeedEvil> There is a major problem with argon.
[15:08:19] <SpeedEvil> You have to make pirate noises every time you go in the shop.
[15:08:29] <malcom2073_> SpeedEvil: You don't already?
[15:10:16] <CaptHindsight> maybe leave the spindle motor running...
[15:10:36] <SpeedEvil> airflow is baaad
[15:10:37] <CaptHindsight> does it generate enough heat to keep the lathe warm?
[15:10:45] <Jymmm> malcom2073_: fill the garage with hay =)
[15:10:46] <malcom2073_> Unloaded? Nah
[15:10:56] <SpeedEvil> Jymmm: and horses
[15:11:07] <Jymmm> Yep, horse poo is steamy =)
[15:11:26] <CaptHindsight> thirsty horses lick the water off the lathe
[15:11:29] <malcom2073_> I have a huge heater I could leave running, but at a dollar an hour.... meh
[15:11:51] <Jymmm> malcom2073_: Seriously, a heavy blanket and a lightbulb is all you need
[15:11:54] <CaptHindsight> and you can eat the horses later
[15:12:04] <Jymmm> CaptHindsight: why later?
[15:12:26] <malcom2073_> the mill isn't a very.... coverable shape, but yeah I can get a really large blanket heh
[15:12:29] <SpeedEvil> http://www.ebay.co.uk/itm/SINGLE-DOUBLE-KING-SIZE-BRAND-NEW-ELECTRIC-WASHABLE-HEATED-UNDER-BLANKET-/221588950323?var=&hash=item3397bb0d33:m:mQ9XaIZ_I2WCpUeu57MGUIg
[15:12:36] <CaptHindsight> Jymmm: he has to solve the rust problem first
[15:12:45] <malcom2073_> CaptHindsight: I don't have rust problems *yet*
[15:12:46] <malcom2073_> :P
[15:12:54] <Jymmm> CaptHindsight: Ah, a spring time feast.... got it!
[15:13:50] <CaptHindsight> the problem with new electric blankets is the stupid safety shutoff after 10 hours
[15:14:03] <Jymmm> heh
[15:14:08] <Jymmm> thrift store
[15:14:12] <Jymmm> malcom2073_:
http://www.reptileuvinfo.com/html/watts-heat-lights-lamp-heat-output.html
[15:14:21] <SpeedEvil> CaptHindsight: not all have it
[15:14:26] <Jymmm> malcom2073_: you could even use a 25W bulb
[15:14:29] <SpeedEvil> CaptHindsight: especially not all on ebay
[15:14:33] <CaptHindsight> I guess stupid people were baking themselves
[15:14:40] <CaptHindsight> maybe it's just in the USA
[15:15:03] <Jymmm> I like the 10hr shutoff, especially when you forget to turn it off
[15:15:11] <SpeedEvil> http://www.ebay.co.uk/itm/ELECTRIC-LUXURY-SOFT-FLEECE-CHOCOLATE-HEATED-WARM-THROW-OVER-SOFA-BLANKET-/141454885563?var=&hash=item20ef5e42bb:m:mJSlBINVWJXSgwoniy2qxzQ - furry mill cover
[15:15:13] <SpeedEvil> :)
[15:15:33] <CaptHindsight> Jymmm: I hotwire mine
[15:15:42] <CaptHindsight> make for good incubators
[15:15:57] <Jymmm> Hey, fleece is REALLY good for holding heat in. I got a 10F degree differencial on a fleece curtain
[15:16:24] <CaptHindsight> last spring I tried to find a heating pad or electric blanket without a safety timer
[15:16:25] <Erant> Rather, air is really good for holding heat in and fleece has a lot of static air
[15:18:23] <SpeedEvil> CaptHindsight: wiring out the timer is trivia
[15:18:24] <SpeedEvil> l
[15:19:16] <CaptHindsight> what else is low cost? Heating pad, fish tank heater...
[15:19:25] <CaptHindsight> engine block heater
[15:19:27] <Jymmm> lightbulb
[15:19:41] <Jymmm> farmers have been using them for decades
[15:19:42] <XXCoder> old overclocked cpu
[15:20:04] <CaptHindsight> Jymmm: but they don't work in the dark
[15:20:07] <Jymmm> pipe the hot water heater exhaust thru the mill =)
[15:20:17] <XXCoder> CaptHindsight: get darklight ;) jk
[15:20:46] <renesis> attach mains V to one end of the table, GND to the other
[15:20:47] <Jymmm> CaptHindsight: Which, the lightbulb , farmer, or the chickens?
[15:20:53] <renesis> why you guys make everything so complicated
[15:21:20] <Jymmm> renesis: silly lil things called circuit breakers
[15:21:32] <renesis> i dunno, wedge it with a bic pen tube
[15:21:37] <renesis> man i gotta think of everything
[15:22:13] <renesis> or just hold it open after connecting
[15:22:29] <renesis> maybe want an oven mit for that
[15:22:33] <Jymmm> renesis: wedge teh mill against the breaker?
[15:22:48] <renesis> i mean if you dont got a bic pen, sure
[15:22:59] <CaptHindsight> Jymmm: I've never seen a lightbulb that works in the dark
[15:23:17] <Jymmm> CaptHindsight: did you lick it?
[15:23:42] <renesis> i wonder if they explode when you do that
[15:24:42] <CaptHindsight> Jymmm: is that the trick? I thought that was only for batteries
[15:24:59] <Jymmm> CaptHindsight: It's for EVERYTHING... just LICK IT!
[15:25:22] <renesis> batteries you have to roll in your hand
[15:25:28] <XXCoder> CaptHindsight:
http://www.alibaba.com/product-detail/Screwbase-Ceramic-Infrared-Heating-Elements-With_60136435422.html
[15:25:38] <XXCoder> it generates heat IR with no light
[15:25:54] <XXCoder> im sure theres some in aliexpress too
[15:25:57] <Jymmm> Why? Does the mill need to sleep in the dark?
[15:26:26] <XXCoder> Jymmm: capt apparently has chickens there? he did menion chickens
[15:26:30] <XXCoder> they need to sleep
[15:26:40] <CaptHindsight> how about the walls of a frost free refrigerator? if you cover a lathe will it also keep the dew off of it?
[15:26:45] <Jymmm> XXCoder: That's why you use a red lightbulb
[15:26:54] <SpeedEvil> CaptHindsight: that's not what they do
[15:27:19] <SpeedEvil> CaptHindsight: frost free refrigerators are kept frost free by there being a place cooled to below the temperature of any point in the user cabinet
[15:27:29] <SpeedEvil> which is periodically automatically defrosted
[15:28:01] <CaptHindsight> so can't he just put the lathe in a colder place, like a refrigerator/iceboox?
[15:28:14] <Jymmm> or outside =)
[15:28:51] <Jymmm> just open the garage door, no more condensation =)
[15:28:56] <malcom2073_> Sometimes, I wonder why I even ask questions here :P
[15:29:10] <XXCoder> because you like it.
[15:29:17] <Jymmm> what XXCoder said
[15:29:23] <SpeedEvil> If he was to seal the room properly, and then run a dehumidifier
[15:29:27] <SpeedEvil> then that would work
[15:29:36] <SpeedEvil> But is often really annoying to do in practice
[15:29:38] <CaptHindsight> Jymmm: then he'll need a gate to keep the horses inside
[15:29:43] <malcom2073_> Jymmm: That doesn't work
[15:30:07] <SpeedEvil> malcom2073_: it sort-of-does unless you get external mist
[15:30:26] <SpeedEvil> malcom2073_: airflow reduces dew due to diurnal temperature swings
[15:30:29] <Jymmm> CaptHindsight: Nah, just a chair...
http://sadmoment.com/wp-content/uploads/2013/11/Horse-Tied-To-a-Small-Chair-Thinks-It-Cant-Walk-Around.jpg
[15:30:33] <malcom2073_> SpeedEvil: Then why do cars get condensation in the morning?
[15:30:49] <Jymmm> malcom2073_: Yes it does =)
[15:30:51] <malcom2073_> The dew point changes faster than the metal can change temperature
[15:30:53] <SpeedEvil> malcom2073_: that's different. That's due to radiative cooling of the outside skin to space
[15:30:58] <malcom2073_> Hah
[15:31:05] <Jymmm> malcom2073_: deperature differencial
[15:31:11] <Jymmm> temperature*
[15:31:22] <SpeedEvil> The metal is cooled below air temp
[15:31:34] <SpeedEvil> if the metal has a roof over it, then it's cooled only to air temp
[15:31:55] <Jymmm> malcom2073_: horse/moving blanket and a lightbulb, (seriously)
[15:31:56] <SpeedEvil> (but when the day warms up, you can get condensation on cold stuff - which is mitigated by airflow in some cases
[15:32:29] <malcom2073_> Rofl
[15:32:30] <SpeedEvil> malcom2073_: Carefully read the descriptions on ebay electric blankets and find ones without timers
[15:32:48] <malcom2073_> Jymmm: Yeah that's what I may try
[15:33:18] <Jymmm> Put the lightbulb on the ground, heat rises. The blanket(s) keep the heat in
[15:33:46] <malcom2073_> Yeah I need to make some covers for thins on the mill, to prevent the blankets from being one-time use
[15:34:03] <Jymmm> malcom2073_: plastic tarp then blankets?
[15:34:15] <Jymmm> malcom2073_: and cover it no later than 3pm
[15:35:02] <CaptHindsight> I'd couple the lightbulb to the lathe somehow. Heat transfer by conduction will be more efficient than by conduction or radiation. (In this example)
[15:35:33] <Jymmm> It's not gonna matter much really
[15:35:39] <malcom2073_> This is more the mill than the lathe
[15:35:50] <malcom2073_> The mill has way more unpainted surfaces that will rust than the lathe
[15:35:58] <CaptHindsight> Jymmm: but he's in the eastern time zone so do you mean by noon your time?
[15:36:06] <XXCoder> malcom2073_: not under daily use eh
[15:36:34] <malcom2073_> XXCoder: Nope, about once every few days
[15:36:43] <Jymmm> CaptHindsight: "local time"
[15:36:46] <malcom2073_> If it's a bad week at work, much less heh
[15:37:35] <Jymmm> CaptHindsight: I've found you lose "heat of the day" if you go past 3pm
[15:38:46] <malcom2073_> I don't come out to use the shop until after 5-6pm anyway
[15:39:00] <CaptHindsight> Jymmm: my shop gets warmer until ~5pm (local time), it starts ~10am this time of year
[15:39:32] <Jymmm> CaptHindsight: Seems to taper off around 4pm though
[15:39:52] <Jymmm> I say 3pm, to have the least loss
[15:40:17] <Sync> ssi: an aerostat floating around seems to be fun
[15:40:40] <Jymmm> malcom2073_: solar 5mm LED =)
[15:46:00] <malcom2073_> Well got my mill fixed at least, pulley sleeve repaired and in place
[15:47:37] <CaptHindsight> "Anyone who sees the aerostat is advised to contact 911 immediately," 243-foot-long, helium-filled military surveillance blimp broke free of its mooring
[15:47:46] <CaptHindsight> http://www.baltimoresun.com/news/maryland/harford/aberdeen-havre-de-grace/bs-md-jlens-blimp-loose-20151028-story.html
[15:47:54] <CaptHindsight> they must be joking
[15:47:56] <fenn> and the robot uprising begins...
[15:48:14] * Jymmm fires up the 500KV tesla coil!
[15:48:53] * XXCoder warms up his TARDIS> Geez been a while.
[15:49:10] <CaptHindsight> "the aircraft use sophisticated radar to see up to 340 miles in any direction, which covers an area from North Carolina to the Canadian border."
[15:49:17] <Jymmm> XXCoder: just introduce it to my tesla coil, it'll warm up =)
[15:49:28] <CaptHindsight> but we aren't sure where it is?!
[15:49:50] <fenn> the radar wasn't necessarily turned on
[15:49:50] <XXCoder> lol
[15:49:58] <Jymmm> CaptHindsight: its stealth technology!!!
[15:53:06] <fenn> i think this was the first or second such blimp to be deployed in the US?
[16:02:19] <Jymmm> HAHAHAHAHAHAHAHAHA
[16:02:36] <Jymmm> Look at the VERY bottom-right corner...
http://dione.net/crud/20150714_164426.jpg
[16:02:58] <XXCoder> lol
[16:03:15] <malcom2073_> mmmm yummy
[16:03:51] <Jymmm> So LICK IT.... LICK IT GOOD!!!
[16:04:30] <malcom2073_> Woohoo mill cuts again!
[16:04:57] <Jymmm> Cuts the condensation?
[16:05:09] <malcom2073_> Yep, loads the motor down but it cuts through
[16:05:17] <Jymmm> lovely
[16:05:49] <malcom2073_> If I win this auction for a vice in a week and a half, I'll be all set
[16:05:52] <malcom2073_> vise
[16:06:44] <Jymmm> lol it is dragging 2 miles of moooring cable. There are reports of power outages in Pa in various places
[16:07:26] <malcom2073_> That may explain the power flickering and going out a couple times here
[16:07:41] <malcom2073_> Aberdeen proving grounds isn't that far south of me
[16:15:26] <JT-Shop> bet I don't cut this sheet of siding backwards
[17:11:12] <Deejay> gn8
[17:16:27] <Tom_itx> JT-Shop, did you try that once already?
[17:16:41] <Tom_itx> you could always hang it on the back side instead
[17:35:55] <gonzo_> any mesa experts on chan this eve, could answer a question please
[17:37:40] <PCW> might be
[17:37:54] <gonzo_> trying to understand how the PC sode of hm2 knows what firmware is loaded on the mesa card. In the case of 7i43 or similar, you do a config=..... but on the 7i90 the firmware is preloaded. So how does the pc side know how to talk to the card?
[17:37:58] <gonzo_> eve peter
[17:38:01] <gonzo_> just the man
[17:38:57] <andypugh> All the firmwares talk the same language, and tell the PC what they have in them.
[17:40:13] <gonzo_> ok, so the board tells the pc what pin/values it has available?
[17:40:18] <andypugh> (and, if they tell the PC that they have a smart-serial module then the PC tells the smart-serial to interrogate all the smart serial ports for connected devices and they report back their capabilities and what they would like their pins to be called.
[17:41:07] <andypugh> The FPGA boards just say how many of encoder/resolver/pwmgen/stepgen etc they have.
[17:41:34] <rene-dev-> PCW: is there a way to change the smartserial timeout?
[17:42:13] <gonzo_> ok, that makes more sense to me now.
[17:42:37] <PCW> which timeout?
[17:42:37] <gonzo_> is there somewhere I can find a list of what the fpga has told the PC what is avail??
[17:42:49] <gonzo_> is that in the dmesg? Or somewhere else?
[17:43:06] <PCW> mesaflash will do it
[17:43:26] <gonzo_> is that working now?
[17:43:58] <PCW> yes:
[17:44:00] <PCW> mesaflash --device 7i90 --addr 0x378 --readhmid
[17:44:08] <PCW> (for example)
[17:44:24] <gonzo_> ah, nice. I think last time it had to be done through dos
[17:44:49] <gonzo_> I'm getting back to this project and am having to start from scratch
[17:45:14] <rene-dev-> I am implementing smartserial on my servo drive, and I am getting lots of error = (3) Timeout
[17:45:27] <rene-dev-> but logic analyzer shows no error in the protocol
[17:48:48] <andypugh> gonzo_: Alternatively, at the terminal echo 5 > /proc/rtapi/debug to increase the debug level then loadt the hostmot2 and hm2_NNNN driver and then dmesg will list all the stuff found.
[17:49:11] <PCW> how far (in SSLBP states) have you gotten (passed the cookie request/reply etc)
[17:49:29] <rene-dev-> the drive takes a bit longer to answer, as it is busy doinf servo drive stuff:
https://www.dropbox.com/s/48ol5vq2awbs9t7/Screenshot%202015-10-28%2023.20.16.png?dl=0
[17:49:36] <rene-dev-> all the way to process data
[17:50:00] <rene-dev-> as far as I can see... how do I read that?
[17:50:10] <PCW> the timeouts are set fairly slow until the process data part starts
[17:50:18] <rene-dev-> BTW, I build a protocol analyzer for sigrok:
https://www.dropbox.com/s/hhc4vl7u6vrng0f/Screenshot%202015-10-28%2017.17.07.png?dl=0
[17:50:25] <rene-dev-> how low?
[17:50:44] <PCW> let me check
[17:50:46] <rene-dev-> and where are they set? where do I see the SSLBP state?
[17:51:04] <PCW> its in the CSR
[17:52:01] <rene-dev-> can I set that from hal?
[17:52:31] <andypugh> rene-dev-: Ooh! I take it that the Mac implementation needs a USB-based scope, not GPIB?
[17:52:56] <Sync> andypugh: a saelea clone will do
[17:52:58] <rene-dev-> andypugh its a saleae logic... not a scope
[17:53:08] <Sync> ~saleae
[17:53:08] <andypugh> (My scope is “A Classic” and only has GPIB)
[17:53:17] <PCW> I think there may be a hal pin for it
[17:53:17] <rene-dev-> mine as well, it has a z80...
[17:53:57] <PCW> if not it can be read with raw-read (well and a bit of masking)
[17:53:58] <andypugh> Not sure mine has a CPU at all :-)
http://www.komu.jp/336.html
[17:54:20] <Sync> yes it has
[17:54:36] <Sync> I got the one after that one
[17:54:43] <andypugh> I guess it must habe something for the charactger generator
[17:54:52] <PCW> sserial timeout is 400 usec at at startup
[17:56:11] <rene-dev-> servo loop is polling dma rx at 200usec, so that is the maximum delay possible
[17:56:39] <PCW> then its changed to the process data turnaround time + 40 usec (after the first Doit)
[17:58:45] <rene-dev-> that explains the timeouts... how do I change that?
[17:59:02] <rene-dev-> linuxcnc is running at 1khz, I am at 5, so there is plenty of time
[17:59:56] <rene-dev-> im getting loads of (13) Communication error and (3) Timeout and (4) Extra character
[18:00:24] <rene-dev-> but in general it appears to work, when I set fault-inc to 0
[18:01:05] <andypugh> glad you are finding my super-elaborate fault masking system useful :-)
[18:01:31] <rene-dev-> explain to me how it works :D
[18:01:35] <PCW> Its possible to increase these times but would require special firmware
[18:02:11] <rene-dev-> is that in the vhdl or dumbass assembly?
[18:03:18] <rene-dev-> I dont want to use an interrupt...
[18:04:00] <andypugh> rene-dev-: It is described here:
http://www.linuxcnc.org/docs/html/man/man9/sserial.9.html
[18:04:28] <PCW> well a faster tic clock that only does comms every tic is a possibility
[18:06:01] <PCW> but requires atomicity guarantees with you 5 KHz tic data
[18:06:30] <PCW> We have 200 KHz tics on some remotes
[18:07:31] <rene-dev-> yes, but you only shift data across, we do a lot of calculations
[18:07:53] <PCW> We do a lot of calcs as well
[18:08:27] <JT-Shop> Tom_itx, actually the drops from the north gable will do the south gable
[18:08:37] <PCW> but typically only the the process data needs the atomicity guarantee
[18:10:04] <rene-dev-> yes, I could go up to 10 khz, but that still does not solve the problem
[18:10:18] <rene-dev-> but 10 khz pid ok for most motors
[18:10:55] <PCW> I think we do this on remotes:
[18:10:57] <PCW> RX --> IRQ --> software FIFO --> polled by foreground task --> software FIFO --> TX
[18:11:20] <rene-dev-> fifo is done in hardware
[18:11:35] <PCW> our foreground task is never interrupted for more than about 20 usec
[18:11:45] <rene-dev-> on the dspic?
[18:12:07] <PCW> we have a little hardware FIFO but not big enough
[18:12:21] <gonzo_> PCW, trying the mesaflash, I'm getting an error that I must select transport layer?
[18:12:42] <PCW> Yes DSPIC the 7I90 sserial remote is all polled
[18:12:56] <rene-dev-> at 200 khz?
[18:13:21] <PCW> Yeah I had forgotten that you need to specify EPP
[18:14:01] <PCW> The 7I90 sserial remote has no other tasks so polling is about 7 MHz or so
[18:14:40] <PCW> (just checking timeouts etc)
[18:16:18] <gonzo_> PCW, ok. better. Does the --readhmid
[18:16:18] <gonzo_> just read the pins from the firmware, without writing to the fpga?
[18:17:01] <PCW> yeah thats all readhmid does
[18:33:49] <PCW> Probably need to change this for a sserial remote with a lot of reply time jitter
[18:33:51] <PCW> timeoutfudge 20 %const 40 uSec added to process data turnaround time for sslbp at 2 usec timer
[18:37:54] <rene-dev-> where can I find the assembler for the cpu?
[18:44:35] <ssi> andypugh: I've been working on trying to get sigrok to work with my rigol dso... in theory it should work but I haven't gotten there yet
[18:48:25] <rene-dev-> I guess its not possibel to adjust via csr from hal?
[18:48:44] <PCW> The assemble is TASM ( a table driven assembler) but realy you dont want 200 usec of random comms jitter
[18:48:45] <PCW> How long does the servo interrupt the foreground task? maybe it would be better if the sserial remote was in the foreground
[18:48:51] <PCW> assembler
[18:49:44] <PCW> (rather than polled synchronously with the servo interrupt task)
[18:52:46] <rene-dev-> there is no foreground task, all the stuff is done in one 5khz interrupt, except usb comms, that is done in the main loop
[18:53:09] <rene-dev-> but works with 10khz as well... I try a faster interrupt for sserial
[18:54:43] <PCW> SSLBP assumes remotes have low jitter (<40 usec) and better than about 500 usec worst case response times
[18:56:00] <rene-dev-> its not random jitter, there is no point in having the data early if it is used at 5khz anyway, and only updated at 1
[18:57:01] <rene-dev-> staying below 100 is no problem
[18:58:09] <PCW> if the receive is polled at 5 KHz its will have random 0..200 usec delays relative to the (non synchonous) requests
[18:59:26] <PCW> (not quite random but some beat frequency because of linuxcnc/ 5KHz clock timebase differences plus linuxcnc jitter)
[18:59:45] <rene-dev-> but we are on hard realtime stuff, always less jitter than the rtapi :D
[19:00:27] <PCW> Yep but not the same timebase (unless you sync your thread to access)
[19:01:25] <rene-dev-> I dont want to sync the mcu to the jitter of linuxcnc...
[19:03:41] <rene-dev-> but similar issue with clk/dir, when you poll it at a fixed rate, you have jitter due to the rational clock ratio
[19:04:02] <PCW> so I would expect a slow variation in delay from baseline to 1/your polling period except when the are
[19:04:04] <PCW> almost in sync and then random full jitter excursions as linuxcncs thread hits a bit early or late
[19:04:46] <PCW> the beat frequency between timebases
[19:06:02] <PCW> I think Jepler has a Python D8 assember but may not admit it
[19:06:39] <rene-dev-> good to know^^
[19:07:55] <andypugh> I assume that flashing a 6i24 with a 5i23 bitfile would fail to be useful?
[19:08:09] <rene-dev-> but the value we are transfering is not affected by the jitter, they are just floats
[19:08:58] <PCW> well it causes some jitter in the position loop
[19:09:58] <PCW> probably not a big issue unless you are after very high precision at high accelerations
[19:10:22] <gonzo_> PCW, have loaded 7i90_epp_svst4_8_ado into the board. I'm playing with one of the demo setups for a simple stepper machine. I'm getting an error from the hm2-stepper.hal, that 'hm2_7i90.0.read' not found
[19:10:45] <PCW> andypugh: mesaflash should not allow you to do that
[19:11:36] <andypugh> OK, so I need to make a 7i44 / 7i85 / 7i49 bitfile for the 6i24 I guess. I doubt that’s a conventional config
[19:12:05] <PCW> gonzo_ did you change the card name in the ini file?
[19:12:45] <PCW> the 5I23 pinout file for it must exist and should work
[19:12:55] <gonzo_> nope, it looked fine. Was already 7i90
[19:13:01] <andypugh> PCW: Dead link on the 6i24 page: The requested URL /software/parallel/6i24.zip was not found on this server.
[19:13:01] <PCW> what size 6I24?
[19:13:20] <PCW> 6i24s use 5i24 firmware
[19:14:53] <andypugh> I think I might have messed up. For some reason I got the 6i24-16. I am sure I intended to get the 25.
[19:15:22] <PCW> should not matter
[19:15:35] <andypugh> RESMOD fits on the 16?
[19:16:56] <andypugh> Ah, look, a 5i24_16_rmsvss6_12_8.bit file exist :-)
[19:19:56] <PCW> Yes a -XC6SLX16 is much bigger that the FPGA on a 5I23
[19:20:27] <andypugh> And I recognise two other configs in the downloaded source that are mine. (PIN_ANDY1_72.vhd sounds like me, as does PIN_HARRISON.vhd)
[19:21:06] <PCW> which do you want?
[19:22:50] <PCW> both have resolvers the Harrison one looks like is has a 7I49/7I39/7I44
[19:23:31] <PCW> sorry andy1 has no resolvers
[19:25:09] <rene-dev-> PCW: ok, thanks for your help, I want to be compatible with the stock mesa firmware, so I find some way to get the timing right.
[19:26:03] <PCW> Thanks for that, my desire to poke at that firmware is not high :-)
[19:28:28] <rene-dev-> no problem, I would have done it myself, I did some fpga stuff already... so not adjustable via the csr?
[19:29:01] <PCW> At one time we considered measuring the worst case return time, and that might have fixed your issue
[19:29:02] <andypugh> PCW: Actually, the already-existing 5i24_16_RMSVSS6_8_72.BIT file looks perfect..
[19:29:02] <PCW> (This would probably require adding random delays so we get good sampling statistics)
[19:29:21] <PCW> well Jolly Good!
[19:30:07] <andypugh> I assume 7i84 just uses GPIO and the channels just need setting up with the right directions?
[19:30:07] <PCW> Unfortunately its not adjustable via CSR since the fudge number is a constant and not a variable)
[19:30:10] <rene-dev-> but it would be helpful to know what causes Communication error and Extra character, is that timeout related as well? I could not see where they come from by looking at the sources...
[19:30:41] <PCW> 7I84 has fixed inputs and outputs (32 inputs 16 outputs)
[19:31:11] <andypugh> Yes, so I need to set the GPIO directions to suit?
[19:31:28] <andypugh> Or do some bitfiles control the direction?
[19:31:29] <PCW> yes extra char errors could be data received after we timed out, and cleared the RX FIFO
[19:31:54] <rene-dev-> ah, ok
[19:32:12] <PCW> The 7I84 has no direction options (only inputs and outputs)
[19:32:16] <andypugh> I am being daft. 7i84 is smart-serial
[19:32:26] <PCW> (yeah no GPIO)
[19:33:08] <andypugh> I was assuming I had bought 3 cards to suit the 3 headers on the 6i24
[19:34:07] <PCW> the 7I90 can be used as a 72 TTL level I/O sserial card but its config just uses open drain so there's no access to direction
[19:34:09] <andypugh> But, in fact, I will have a spare header. Hmm, and I do have a spare 7i39….
[19:36:28] <andypugh> I will keep the 7i39 in mind in case I want some live tooling :-)
[19:57:10] <andypugh> Interesting, the 6i24 has 4 user-LEDS but Hostmot2 only makes pins for two of them.
[19:57:42] <andypugh> (Not that I have ever found a huge amount of use for them)
[19:58:43] * Wolf_ wishes he had a clue about anything talked about in here over the last couple hours…
[19:59:52] <ssi> Wolf_: I wish you did too, since you're supposed to be part of this project :)
[20:00:37] <Wolf_> yeah, well I didnt know it needed this much work, I usually fill the role of clueless enduser well tho :)
[20:00:51] <ssi> are you gonna be able to assemble these things?
[20:00:57] <Tom_itx> it's not that difficult really
[20:01:07] <Wolf_> yeah, I can do hardware no problem
[20:01:12] <rene-dev-> the stmbl?
[20:01:22] <ssi> Wolf_: you're comfortable with 603 and 0.5mm pitch qfps?
[20:01:30] <Wolf_> yeah
[20:01:31] <ssi> ok
[20:15:02] <Jymmm> PCW: I'm waiting for this to arrive...

[20:27:13] <petefromtn> Evenin' folks
[20:30:46] <andypugh> Jymmm: Just how many LED torches do you own?
[20:31:14] <Jymmm> counting...
[20:32:15] <Jymmm> maybe 9 or 11 I guess
[20:34:00] <Valen> this many?
http://imgur.com/a/sxZfd
[20:34:02] <Valen> ;-p
[20:34:14] <Jymmm> andypugh: This is (hopefully) a everyday carry
[20:35:11] <Jymmm> Valen: what are those?
[20:35:29] <andypugh> I am thinking about putting my tritium light on my key ring to see if it helps find my keyhole
[20:35:31] <Valen> torches we made
[20:36:32] <Jymmm> andypugh: you might have better luck with these
https://www.fasttech.com/p/1058600
[20:37:05] <Jymmm> andypugh: they're pretty good too, either momentary or on/off
[20:37:24] <andypugh> But I have the tritium vial, and it’s kind of cool
[20:37:58] <Jymmm> =)
[20:38:24] <Jymmm> andypugh: Oh, and I have "other" leds as well, besides torches
[20:38:42] <Jymmm> and related controllers/drivers
[20:40:25] <zeeshan|2> andypugh: still know how to read stress-strain diagrams? :-)
[20:40:47] <zeeshan|2> Jymmm: what are those poops
[20:40:51] <andypugh> I am not sure I do. I can probably figure out uniaxial ones
[20:40:59] <zeeshan|2> im going to test you
[20:41:04] <zeeshan|2> and your years of memory :D
[20:41:04] <Jymmm> zeeshan|2: ?
[20:42:05] <Valen> Jymmm: they are multi mode, and push on push off ;->
[20:42:16] <Valen> short press/release turns it on in high power
[20:42:31] <Valen> press and hold starts cycling modes, starting off from super dim
[20:42:46] <Valen> press and hold when its on to cycle modes
[20:42:50] <Valen> short press turns it off
[20:43:03] <zeeshan|2> classify this type of polymer:
[20:43:03] <zeeshan|2> http://i.imgur.com/avX6PMM.png
[20:43:09] <Jymmm> Valen: 5mm leds???
[20:43:13] <zeeshan|2> http://i.imgur.com/xlSAAT7.png
[20:43:13] <zeeshan|2> and that
[20:43:14] <zeeshan|2> :-)
[20:43:17] <andypugh> How is possible for them to make a USB plug-top charger and post it from china to the UK for 99p including postage?
[20:43:27] <Valen> 2x, one is ~160deg and the other is 15 deg
[20:44:13] <Jymmm> andypugh: I think postage is subsidised, but also realize that even one cent profit, is profit.
[20:45:01] <Tom_itx> Jymmm, you don't have one like this:
http://tom-itx.no-ip.biz:81/~webpage/scope/led_harness_on.jpg
[20:45:40] <andypugh> zeeshan|2: The first one has no apparent data for 80C
[20:45:55] <Jymmm> Tom_itx: You're right, mine has 96 leds
[20:45:56] <zeeshan|2> yes
[20:45:58] <zeeshan|2> its pretty much failed
[20:46:01] <andypugh> Ah, no, wait, I see it now
[20:46:04] <zeeshan|2> at 0.2 strain
[20:46:05] <zeeshan|2> early
[20:46:13] <zeeshan|2> ignore some of those circles
[20:46:18] <zeeshan|2> i didnt clean up the after fracture data , sorry
[20:46:59] <zeeshan|2> im thinking the second one looks like a typical polymer tensile test curve
[20:47:01] <Tom_itx> Jymmm the fenix is working nicely for what i got it for
[20:47:02] <andypugh> I never did polymers you know, they hard hardly been invented when I was a lad :-)
[20:47:14] <zeeshan|2> but the first one looks like something that is very linear in the beginning
[20:47:22] <zeeshan|2> but then hardens a bit
[20:47:27] <zeeshan|2> hahaha
[20:47:38] <zeeshan|2> i hate polymers. :[
[20:47:42] <Jymmm> Tom_itx: Cool, just remember to semi-unscrew the battery cap when you store/not using it
[20:47:50] <zeeshan|2> im just happy my apparatus is giving some REAL results now
[20:47:53] <zeeshan|2> that show some REAL trends!!
[20:47:57] <andypugh> Yes, the first one is somewhat strain-harding, the second is wierd.
[20:48:34] <zeeshan|2> im analyzing the data
[20:48:42] <zeeshan|2> where i stuck both these 2 different polymers togetrher (lamination)
[20:48:46] <zeeshan|2> and did the same test
[20:48:55] <zeeshan|2> im really hoping its a linear combination of the two curves
[20:49:16] <Jymmm> Valen: Are those to be a trendy cool wood keychain flashlight thingy?
[20:49:18] <andypugh> It should be. It would be if they weren’t bonded, after all
[20:49:26] <Jymmm> Valen: ...usb recharged
[20:49:34] <zeeshan|2> they were glued together
[20:50:02] <andypugh> That should just make them equivalent to a lot of arbitrarily short specimens.
[20:52:17] <Jymmm> Valen: what is the 2nd (yellow die) led?
[20:53:18] <Valen> yeah its usb chargable wooden keychain lights
[20:53:22] <Valen> that is the wide angle
[20:53:25] <Valen> pulls 60ma
[20:53:31] <Valen> lights up an entire room
[20:53:40] <Valen> (in warm white)
[20:59:20] <Jymmm> Valen: pwm?
[20:59:41] <Jymmm> Valen: is that 5 8 or 10 mm ?
[21:00:39] <Jymmm> andypugh: Yes, I openly admit I have an obsession with light, be it led, laser, pyrotechnics, etc =)
[21:03:00] <Jymmm> andypugh: the one I linked to is to replace a defective one I've had on my keychain for years.
[21:03:24] <Jymmm> andypugh: and took my 18 months to finally order it =)
[21:03:27] <Jymmm> me*
[21:04:13] <jdh> slow internettes?
[21:04:16] <Jymmm> Valen: Is that an oring you fill the cutout with?
[21:04:29] <Jymmm> jdh: No, I'm VERY picky.
[21:04:52] <Valen> on the phone atm
[21:04:55] <Valen> 5mm
[21:04:59] <Valen> which cutout?
[21:05:05] <Valen> and its linear
[21:05:14] <Jymmm> jdh: Well, also I had been getting the GF the "right light for her" as she has difficult with tail cap buttons.
[21:05:29] <Jymmm> Valen: the button curve cutout
[21:05:51] <Jymmm> jdh: she has nerve damage in her fingers
[21:06:19] <jdh> I like ones a little larger than that.
[21:06:21] <Jymmm> jdh: so I went thru a lot to find "side button" flashlghts
[21:06:45] <jdh> http://uwlightdude.com/product/ld-35/
[21:06:47] <Jymmm> jdh: The linked one abive is for my keychain, so it's huge actually
[21:08:55] <Jymmm> jdh: This is my primary

[21:09:12] <Jymmm> jdh: great combiation of flood and throw
[21:09:17] <Valen> yeah that is oring material
[21:09:48] <Jymmm> Valen: did you cut it or is there an unseen groove for it to follow?
[21:09:51] <Valen> we did some with cast urethane but it was hard getting it lined up
[21:09:53] <Valen> glue it in
[21:10:04] <Valen> sorry hard stopping it running in the wood grain
[21:10:07] <Jymmm> Valen: cool, how much?
[21:10:16] <zeeshan|2> Jymmm: i got that one too
[21:10:17] <zeeshan|2> i like
[21:10:23] <zeeshan|2> i recently bought one in red
[21:10:27] <Valen> $50 Australian paesos + PNH
[21:10:31] <zeeshan|2> so i can maintain night vision
[21:10:40] <Jymmm> Valen: ouch
[21:10:43] <zeeshan|2> or "dark adaption"
[21:10:44] <Jymmm> zeeshan|2: =)
[21:11:03] <Valen> if you want to order 1000 of em I'm sure we could make it cheaper ;->
[21:11:24] <Valen> there is a fair bit of hand finishing in timber though
[21:11:52] <Jymmm> Valen: I was mostly curious on the electronics, a wood flashlight would do me no good.
[21:13:02] <Jymmm> Valen: Now, if you want to toss the guts in an envelope my way...
[21:14:46] <Valen> $40 + P&H lol
[21:14:46] <Jymmm> jdh: andypugh: This is my glovebox light/charger/pwr pack
http://www.kaidomain.com/product/details.S022116
[21:14:57] <Valen> I make the electronics, father makes the housings
[21:15:52] <zeeshan|2> andypugh: isn't it 2am there? :P
[21:16:17] <Tom_itx> don't remind him
[21:16:37] <zeeshan|2> =]
[21:16:45] <Valen> I'll see if we have some PCB's floating around
[21:18:19] <Jymmm> Valen: I couldn't figure out wth the tissue box was... solder mask =)
[21:18:50] <Jymmm> Valen: You know,, they have this new thing called CNC that will do that for you =)
[21:22:10] <Valen> the solder masks were cut on a CnC
[21:22:20] <Valen> sorry solder stencil
[21:22:23] <Jymmm> I mean thte pick and place =)
[21:22:41] <Valen> yeah, if you order 1000 I'll do it PnP
[21:24:09] <Jymmm> You're barking up the wrong tree, I'm VERY picky on such things =)
[21:25:03] <Jymmm> the most expensive light I've bought was this, and it wasn't even for me, but the gf due to her fingers
http://www.amazon.com/Olight-Baton-Cree-XLamp-XM-L2/dp/B00EASUHB0
[21:25:51] <Jymmm> tail is on/off, side button is mode/low battery indicator
[21:27:48] <Jymmm> I'm trying very hard NOT to look at the 10W+ stuff, but the more I find "perfect heatsinks" it's getting very tempting =)
[21:48:33] <Wolf_> I like my nitecore p12
http://amzn.com/B00PW1LEOS
[21:50:23] <Wolf_> and now that I’m looking at that bundle, I’m wondering where I put the battery that came with it… lol
[21:50:56] <Jymmm> Um, in the flashlight?
[21:51:17] <Wolf_> nope lol, I think I have a sony v4 in there right now
[21:51:19] <Wolf_> or a AW
[21:53:02] <Wolf_> have 8x 18650 in different flavors from e-cig and other lights
[21:54:41] <Jymmm> I have 30a samsung for my mechmod
[21:55:05] <Jymmm> those ar ethe only unprotected cells I have
[21:55:13] <Wolf_> arg, I’m sick of this mess around my current “desk”, new goal is to get my office/lab space done in my house so everything isn’t plied up in a 6’x6’ space
[21:56:03] <Jymmm> roll dumster to window, slide arm across desk till it's contents are in dupster, repeat till desk is empty.
[21:56:28] <Wolf_> right now I’m living/working out of a 32’ camper behind the house lol
[21:56:28] <renesis> wolf_: isnt that was lab space is?
[21:56:53] <Jymmm> Wolf_: better than a 7x9 tent
[21:57:04] <Wolf_> yeah, better then a tent
[21:57:20] <renesis> you guys dont sleep in the same room as your electronics and cnc gear?
[21:57:24] <Wolf_> and more sq feet then the apartments across the street from me
[21:57:45] <Wolf_> new room is going to be 380q feet
[22:01:37] <Valen> perfect heatsink?
[22:25:18] <Jymmm> renesis: No, they want their privacy at night
[22:25:43] <Jymmm> Valen: Yeah, many are just expensive so I like to find alternatives
[22:26:00] <Jymmm> Valen: 25, 50, 100W led type
[22:26:22] <Valen> what is a perfect heatsink?
[22:26:31] <Valen> I'd also like a high quality 30W red LED
[22:27:06] <Jymmm> sized to LED; good profile for intended task; reasonably priced
[22:27:23] <Jymmm> why red?
[22:28:25] <renesis> is it for growing stuff?
[22:29:04] <renesis> prob lots of 660nm reds now, i got some 5W star mounted from LEDengine few years ago
[22:30:14] <renesis> anyway, high quality is pretty much anything from mouser/digikey, and red isnt uncommon in high power LEDs, chips and star mounted
[22:32:23] <renesis> damn, still spendy
[22:32:49] <renesis> valen: and a perfect heatsink is a slab of aluminum the size of the earth
[22:33:01] <Valen> transillumination of human body parts
[22:33:02] <renesis> dont worry about fins on that one
[22:33:39] <renesis> does it need to be a single chip?
[22:34:18] <renesis> 30w might be hard to find, 6*5W is prob way easier to source, probably cheaper unless comparing credible manufacturers to china shit
[22:35:29] <renesis> ebay is prob the best place for heatsink extrusions
[22:35:33] <renesis> http://www.aavid.com/product-group/extrusions/search
[22:35:59] <renesis> can use that calculator to get an idea of size/geometry for a given C/W
