[00:08:06] <pink_vampire> any life?
[00:11:35] <FloppyDisk525> none - dead as a door nail.
[00:13:28] <pink_vampire> FloppyDisk525: hehe
[00:13:51] <pink_vampire> i just finish the wiring for the pilot devices
[00:13:53] <FloppyDisk525> yeah, not much going on...
[00:14:23] <FloppyDisk525> I'm not sure what the pilot devices are? I did see your pix of your elec cabinet, looks really nice.
[00:14:51] <pfred1> I'm building a cabinet for my CNC
[00:15:10] <pfred1> I'm using an old desktop PC case
[00:15:30] <FloppyDisk525> Hmm, that hsould work. I've seen the captain does that, good idea and looks decent.
[00:15:38] <FloppyDisk525> perfect for living room milling machines:-)
[00:15:51] <pfred1> well I have a few kicking around
[00:16:01] <pfred1> its a metal box
[00:16:05] <FloppyDisk525> do they kick back?
[00:16:22] <pink_vampire> one sec let me take a picture
[00:16:29] <pfred1> I suppose they do
[00:16:36] <FloppyDisk525> :-)
[00:16:50] <pfred1> not much to take a picture of yet with mine
[00:20:01] <pfred1> I'm not sure how I'm going to lay it out yet http://i.imgur.com/J4vTWzs.jpg
[00:20:49] <pink_vampire> http://i.imgur.com/JoW9IB7.png
[00:22:16] <pfred1> what are those blue boxes?
[00:22:31] <pfred1> they look like time delays
[00:22:49] <pink_vampire> power supplies
[00:22:57] <pink_vampire> 5v 5v 12v
[00:23:04] <pfred1> why is there a 123 block in the bottom of the cabinet?
[00:23:12] <pfred1> added weight?
[00:23:23] <pink_vampire> http://i.imgur.com/aJbuWn5.png
[00:23:43] <pink_vampire> no, just for spacing
[00:23:56] <pfred1> ah
[00:24:33] <pfred1> the board in the lower left of my cabinet I just made it drops high DC down to 12.5 and 5VDC
[00:24:34] <pink_vampire> i'm use it as 1" spacer
[00:25:04] <pfred1> though I'm not sure what I'm going to use the 5VDC for
[00:25:18] <pink_vampire> just get 2 lambda power supplies
[00:25:24] <pfred1> my BOB has its own regulator so I'll feed it the 12.5V
[00:26:15] <pink_vampire> i'm using the 12v for control and the 5v for micro controllers stuff
[00:26:34] <pink_vampire> i'm using 2 c10,
[00:26:36] <pfred1> yeah I don't have any microcontroller stuff
[00:26:43] <pfred1> but if i ever get any I'll have power for it
[00:28:28] <pfred1> my BOB is just some buffer ICs
[00:28:37] <pink_vampire> i have 2 from each power supply
[00:28:47] <pfred1> 2 what?
[00:28:56] <FloppyDisk525> I used to use those types of terminal blocks w/ the screw on the top and the wire in the side.
[00:29:24] <FloppyDisk525> I switched to the spring clamp ones w/ the spring clamp on top and the hole on top. I prefer this method....
[00:29:24] <pfred1> FloppyDisk525 barrier strips?
[00:29:59] <FloppyDisk525> I call them terminal blocks, the yellow, gray, black, blue, green wire terminals you ahve.
[00:30:03] <pfred1> I got a whole mess of them barrier strips where I worked
[00:30:38] <FloppyDisk525> I meant pink had, unless I'm confused. been slow all day...
[00:31:27] <pfred1> like AvE would say, Focus you fawk
[00:31:51] <pfred1> I mean pink's picture of course
[00:32:32] <pfred1> pink_vampire how many VA is that toroid?
[00:32:42] <pink_vampire> 1440w
[00:32:59] <pink_vampire> 72v 20a
[00:33:19] <pfred1> yeah it looks like a big one
[00:33:49] <pink_vampire> http://i.imgur.com/TA5KaAT.png
[00:33:58] <pink_vampire> look at the sharpie
[00:34:28] <pink_vampire> pfred1:
[00:34:40] <pfred1> yes?
[00:35:17] <pink_vampire> did you say the sharpie marker as a scale..
[00:35:23] <pink_vampire> saw*
[00:36:05] <pfred1> what gauge wire is coming out of that toroid?
[00:36:34] <pfred1> I know wire gauges better than felt tip markers
[00:36:53] <pfred1> it looks to be maybe 12 gauge?
[00:37:01] <pfred1> could be bigger though hard to tell
[00:37:35] <pink_vampire> let me see
[00:38:05] <pfred1> there looks to be enough text on the green wire it should say
[00:38:39] <pink_vampire> i cant see them now
[00:38:45] <pfred1> that's OK
[00:38:47] <pink_vampire> it's on the bottom
[00:39:14] <pfred1> that's a big toroid though that's for sure
[00:39:27] <pink_vampire> all the wires in the cabinet is 12 awg
[00:39:31] <pfred1> I picked up a stereo once because it has a big toroid in it
[00:39:59] <pfred1> well it isn't exactly a stereo
[00:40:06] <pfred1> it is more like a 48eo
[00:40:27] <pfred1> or some ungodly number of channels
[00:40:28] <pink_vampire> 48 channels???
[00:40:44] <pfred1> yeah it is a bunch of stereos together it is for a commercial sound installation
[00:40:53] <pfred1> it is a weird piece of gear
[00:41:28] <pfred1> I think it is like 1,200 Watts?
[00:41:36] <pink_vampire> i want to build a transformer with several outputs
[00:41:45] <pfred1> multitap
[00:41:56] <pink_vampire> in 120v ac, out 10v 10v 10v 10v
[00:42:12] <pfred1> you'd liek the transformer I pulled out of a minicomputer
[00:42:29] <pfred1> it is multitapped
[00:43:07] <pfred1> it is a big beast too http://i.imgur.com/vcy2INB.jpg
[00:43:17] <pink_vampire> do you know how to calculate it?
[00:43:28] <pfred1> it is a ratio
[00:43:50] <pink_vampire> i mean turns per volt
[00:43:52] <pfred1> other than losses it is fairly direct
[00:44:04] <pfred1> depends on how many primary turns there are
[00:44:19] <pink_vampire> zero
[00:44:28] <pink_vampire> i have just the core
[00:44:31] <pfred1> lets say you have a 100 turn primary and a 50 turn secondary you would step down 50%
[00:44:50] <pink_vampire> i know..
[00:44:55] <pfred1> or is it the other way around?
[00:45:33] <pink_vampire> i know i need 1:12 ratio to go go from 120 to 10
[00:45:53] <pfred1> yeah it never works out perfectly
[00:46:01] <pfred1> but it's damned close
[00:46:22] <pink_vampire> but how meany turns i need to do for the primary?
[00:46:28] <pfred1> usually what you do is you make the primary then put a couple secondary turns on and measure what you got
[00:46:29] <pink_vampire> 1? 1000?
[00:48:17] <pink_vampire> i know that i need to get enough magnetic resistance so without load it should take close to zero ma
[00:48:19] <pfred1> I'm not sure how you decide how many turns to use
[00:48:39] <pfred1> that sounds good
[00:49:05] <pink_vampire> i have the formulas but the transformer get very hot
[00:49:08] <pfred1> yeah you need enough inductive reluctance
[00:49:31] <pfred1> maybe you need to use thinner wire?
[00:49:38] <pfred1> you use magnet wire?
[00:50:03] <pink_vampire> and i don't know if the diameter of the wire have any effect on that
[00:50:05] <pink_vampire> yes
[00:50:05] <pfred1> I know some people use stranded but I think there's a drawback to using it
[00:50:49] <pfred1> the direction your wind it probably matters too
[00:51:35] <pink_vampire> but i'm using ac
[00:51:40] <pfred1> when I was messing with an auto transformer I came to realize that AC is polarized
[00:52:08] <pfred1> believe it or not ti matters which way around you connect
[00:52:28] <pfred1> before that i never thought it did
[00:52:53] <pfred1> but with 120VAC only one wire is hot
[00:52:57] <pink_vampire> i don't know enough.
[00:53:07] <pfred1> the other wire is effectively ground
[00:53:28] <pfred1> slthough we call it the neutral ereturn
[00:53:41] <pfred1> just because of how we use it
[00:53:47] <CaptHindsight> and the hot is at ground 120 times each second!
[00:54:03] <pink_vampire> all i need is isolated power supply 10v 50ma
[00:54:08] <pfred1> but if nothing is leaking neutral is just like touching the earth
[00:54:39] <pfred1> it has no electrical current flowing through it
[00:55:11] <pfred1> kind of weird
[00:55:33] <pfred1> take a multimeter and measure between the neutral andground
[00:55:39] <pfred1> you should get no reading
[00:56:01] <CaptHindsight> will an AC battery conduct current farther than a DC battery?
[00:56:05] <pfred1> but you'll get a reading between the hot and neutral, or ground
[00:56:20] <pink_vampire> http://www.digikey.com/product-detail/en/cui-inc/PDM1-S9-D9-S/PDM1-S9-D9-S-ND/5306613
[00:56:29] <pink_vampire> this is my other option
[00:56:31] <eeriegeek> hook an ammeter in your neutral leg and it might disagree
[00:56:39] <pink_vampire> to use dc dc converter
[00:56:59] <pfred1> 56ma?
[00:57:06] <pfred1> I can piss more electrons than that
[00:57:29] <pink_vampire> 56ma is fine
[00:57:34] <pfred1> OK
[00:57:35] <pink_vampire> i need 50ma
[00:57:44] <pfred1> yeah then 56ma isn't fine
[00:57:56] <pfred1> you should always have some overhead more than 10%
[00:58:00] <pfred1> more like 100%
[00:58:02] <pink_vampire> even 20ma will be fine
[00:58:09] <pfred1> then 56ma is OK
[00:58:37] <CaptHindsight> depends on where you measure on the neutral
[00:58:48] <pfred1> what an almost worthless part though
[00:59:01] <pfred1> Isolated Module DC DC Converter 2 Output 9V -9V 56mA, 56mA 8.1V - 9.9V Input
[00:59:08] <pink_vampire> the issue is that i need about 20 units like that
[00:59:13] <pfred1> whats in it a loop of wire?
[00:59:52] <pink_vampire> very small toroide and oscillator
[01:00:16] <pfred1> OK so a loop of wire then
[01:00:40] <pfred1> wow it is $4.11?
[01:01:07] <pink_vampire> the cheapest i can get them is 4$~
[01:01:17] <CaptHindsight> is an electrical conductor more like a train conductor or orchestra conductor?
[01:01:38] <pfred1> well if you need them, then you need them
[01:02:12] <pink_vampire> this is why i want to learn how to make a transformer
[01:02:21] <pfred1> my DC to DC converter cost me exactly buttkus
[01:02:28] <pfred1> I made it out of junk i had laying around
[01:02:54] <SpeedEvil> And time.
[01:03:06] <pfred1> SpeedEvil yeah but i like doing it
[01:03:13] <pfred1> or i wouldn't do it
[01:03:34] <SpeedEvil> there is that
[01:04:00] <pfred1> I could have done it a lot faster but I was just having that much fun
[01:04:23] <pfred1> in fact the one i made on a breadboard I did put together quickly
[01:04:53] <pfred1> when I saw how well it worked I thought, I need to make a nice permanent one of these
[01:05:32] <pfred1> it drops 60V down to 12.5 like its nothing
[01:07:06] <pink_vampire> http://www.ebay.com/itm/Wall-Car-Charger-Adapter-5V-1A-USB-Port-US-EU-Plug-For-Samsung-Phone-Portable-/311562188584?var=&hash=item488a8db728:m:m7LxnnWqk0IUPbbry9ZLWPw
[01:07:24] <pink_vampire> 5v for less then 2$
[01:07:25] <pfred1> at first I tried stringing a bunch of diodes together hoping for a 0.7V loss on each one
[01:07:31] <pfred1> that don't work though
[01:07:49] <pfred1> I had like 25 diodes strung together and they dropped barely anything at all
[01:08:20] <SpeedEvil> 16-20V or so typically
[01:09:47] <pfred1> pink_vampire you know what aliexpress is?
[01:09:59] <pink_vampire> yes
[01:10:05] <pfred1> OK
[01:10:23] <pfred1> it is your one stop shop for dodgy cheap electronics
[01:10:34] <pink_vampire> do you know how i can use paypal over there?
[01:10:52] <pfred1> beats me I don't have paypal I just use Visa
[01:12:48] <pink_vampire> i don't like it
[01:13:19] <FloppyDisk525> Pink - I don't think you can use paypal for aliexpress.
[01:13:26] <pink_vampire> and i'n using mouser most of the time to get electronic stuff
[01:13:27] <FloppyDisk525> Different countries and different systems.
[01:14:07] <FloppyDisk525> The problem is that Aliexpress is a competitor to ebay (or at least ebay will see it that way) and no way ebay/paypal
[01:14:17] <FloppyDisk525> will work w/ aliexpress and alibaba.
[01:14:35] <FloppyDisk525> credit cards will work, though...
[01:14:45] <pfred1> then ebay is dumb
[01:14:54] <FloppyDisk525> Well, ebay is rich...
[01:14:56] <pfred1> because they could be makign a percentage on ali's sales
[01:15:17] <pfred1> I haven't shoppedo n ebay in years
[01:15:53] <pfred1> ever since some asshat charged me $5 for shipping and the package said $1.60 right on it
[01:16:15] <pfred1> what, I can't read?
[01:18:13] <pink_vampire> http://www.mouser.com/ds/2/468/RBE-958263.pdf
[01:18:15] <pink_vampire> wtf
[01:18:33] <pink_vampire> RECOM products are not authorized for us e in safety-critical applications
[01:21:19] <pfred1> pink_vampire they have to cover their ass
[01:21:31] <pfred1> all electronics says that
[01:22:14] <pink_vampire> i saw one with out that but it was 38$ each
[01:22:31] <pfred1> well that's what certification costs
[01:23:03] <pfred1> someone had to sit there and beat every one that came off the assembly line with a hammer then see if it still worked
[01:24:07] <renesis> eh? what kind of certification?
[01:25:00] <renesis> for EMC and safety compliance, products were self certified by testing production spec prototypes at a certified compliance lab
[01:25:27] <renesis> i dont know if thats standard for every industry but for consumer electronics thats typical
[01:26:18] <pink_vampire> all i need is 5v 50 ma isolated source.
[01:26:34] <pink_vampire> flashlight + small solar panel
[01:27:08] <SpeedEvil> how isolated/
[01:27:16] <renesis> assembly line QA is for making sure the products are what theyre supposed to be, the assumption being that if it the same as the compliance tested prototype, it will behave the same if tested independently
[01:28:26] <renesis> in reality, changing variables like wire routing have an effect, and things that pass compliance as prototypes dont always pass as shipped products
[01:28:33] <pfred1> http://www.omnicongroup.com/airworthiness-certification.html
[01:29:21] <pfred1> I like the picture of the Global Hawk launching a Hellfire missile on that page
[01:29:41] <pink_vampire> SpeedEvil: isolated in a way that i can use it like it was one more power supply
[01:29:46] <pfred1> when your package absolutely has to be delivered guaranteed
[01:30:38] <renesis> ooooh, youre talking about medical/military/automotive spec?
[01:30:56] <renesis> because they want you to contact them directly
[01:31:00] <pfred1> those would be biggies
[01:31:41] <pfred1> look for the CE China Export mark of assurance
[01:32:11] <renesis> a lot of those parts would be fine for critical apps but you have to clear it with them so they know not to fuck around with your bins
[01:32:15] <renesis> pfft
[01:32:24] <renesis> china CE/UL stuff was such a joke
[01:32:44] <pfred1> boomarang products
[01:32:58] <renesis> wed ask them for cert docs, get something in chinese that looks photocopied 20 times, and realize that its the same fucking doc as for 10 other completely diff parts
[01:33:03] <pfred1> they'll be back in a landfill in china before you know it!
[01:33:37] <renesis> which will work out great for them in 10 years when landfils become resource comoddities
[01:34:09] <pfred1> sometimes i watch e-waste porn on YouTube it is a guilty pleasure of mine
[01:34:16] <renesis> ha
[01:34:30] <pfred1> I see those heaps of electroncis scrap and i just drool
[01:34:56] <pfred1> it makes me want to move to Africa
[01:35:27] <pink_vampire> O_O
[01:35:32] <pfred1> drop that shipping contaner off right here
[01:36:32] <pfred1> https://www.youtube.com/watch?v=WzR79Wv2oJA
[01:36:38] <pfred1> oh yeah
[01:37:17] <pfred1> heaven!
[01:40:22] <pink_vampire> hope you joke
[01:40:27] <pfred1> ifthey just wouldn't burn it it wouldn't be such a problem
[01:41:30] <pink_vampire> i need to finish wiring
[02:29:37] <Deejay> moin
[02:51:58] <pink_vampire> hi Deejay
[02:52:07] <pink_vampire> how are you tonight?
[04:45:30] <XXCoder> heys
[04:46:07] <XXCoder> JT-i3: nice! worked eh
[05:36:20] <SpeedEvil> http://imgur.com/gallery/GY78r - sort of on topic - CNC labels
[05:36:59] <XXCoder> yea never figured wtf that dick-duckbutt thingy is
[05:37:01] <XXCoder> *dick
[05:51:06] <pink_vampire> loading.................
[06:08:04] <jthornton> morning
[06:08:13] <XXCoder> yo
[06:29:01] <Frank_10> hey
[06:29:59] <XXCoder> is for horses
[06:35:15] * Jymmm gives XXCoder a container of hay
[06:35:41] * XXCoder puts it in his nonecludian pocket.
[06:48:20] <jthornton> lol
[07:00:36] * Jymmm guts XXCoder and recycles the hay!
[07:01:05] * XXCoder dies, with hay still in his inverory.
[07:01:25] <Jymmm> Oh no, you don't get off that easily!!!
[07:02:58] <Jymmm> Who here built a rocket stove a ways back from scraps of steel they got from work?
[07:03:47] <XXCoder> me
[07:04:30] <Jymmm> you still have pics?
[07:05:18] <XXCoder> it got burnt up
[07:12:28] <Jymmm> how so?
[07:12:43] <Jymmm> XXCoder: I want to see after pics =)
[07:12:50] <XXCoder> lol
[07:13:00] <XXCoder> you destroperv
[07:13:36] <Jymmm> Nah, I want to see how you fucked up and burnt up 1/4" plate steel =)
[07:14:06] <XXCoder> lol kidding :P
[07:14:18] <Jymmm> pics biotch!
[07:14:41] <Jymmm> I KNOW you took them!
[07:15:50] <XXCoder> lol
[07:15:55] <XXCoder> so you did it eh
[07:17:09] <Jymmm> As I see it, rocket stove, wood gassifiers, or EPA stoves all work on exactly the same principal... Super heat the intake air, which removes the moisture in it so you get a better burn of the fuel, be it solid or the released wood gases.
[07:17:54] <Jymmm> 60% of the energy rom wood is in the gasses, not the solids.
[07:18:03] <Jymmm> from*
[07:29:51] <Jymmm> I'm wondering if the high heat ( >500F ) also does something on the molecular level; like break some bonds between the oxygen (21%) / nitrogen (78% ) in the atmosphere
[07:31:52] <Jymmm> or if it's simply to overcome the heat loss of any moisture mixing with the outgasses (cresote etc)
[07:34:51] <Jymmm> a rocket stove feeds super heated air at/under the fire. Where as many wood gassifiers feed the super heated air at near/ the top of the flames/firebox.
[07:36:42] <sync> I doubt that you would get NOx that much
[07:37:44] <Jymmm> sync: The air you breath is 78% nitrigen, no clue on nitrogen dioxide though
[07:37:52] <Jymmm> mitrogen*
[07:38:08] <Jymmm> bah
[07:39:10] <sync> well, your fire is not going to generate NOx
[07:39:24] <sync> or not a lot
[07:39:54] <Jymmm> http://www.uigi.com/nitrogen.html
[07:40:12] <Jymmm> nitrides
[07:41:59] <Jymmm> But to KISS, I'm just going to go with the idea that the "reburn" is primarily based up on the idea of removing moisture from the intake air.
[07:42:55] <Jymmm> ...ahead of time, allowing for a more effeciant burn of the fuel, and minimal loss of from having to get rid of the moisture too.
[07:45:05] <Jymmm> In a wood stove (or whatever) the fresh air intake can be 40% humidity.
[07:46:20] <Jymmm> If that was routed thru a zig-zag pattern under the firebox, it would be little to no additional mositure being added to the firebox itself.
[07:46:37] <Jymmm> at least in theory =)
[07:58:32] <archivist> nope
[07:58:46] <archivist> just becomes hot moisture
[08:06:27] <gregcnc> I thought EPA stoves just burn the smoke and gas that would otherwise go out the chimney
[08:07:39] <gregcnc> I have a vermont with a catalyst
[08:10:57] <archivist> reburning the exhaust is very different to warming the intake air only
[08:15:52] <gregcnc> Jymmm, some of the talk about wood stoves and various designs borders on over unity speak. It's simple heat transfer and combustion.
[08:16:44] <archivist> getting the efficiency up a bit helps, snake oil does not
[08:34:33] <gonzo_> historic designs I've seen have a fire brick in the mouth of the flue,
[08:35:00] <gonzo_> looks to be used as an ignition for the gases that are trying to pass
[08:43:28] <archivist> anyway me 1 tree 0 this morning :)
[08:58:33] <ToddZ> It is all about burning more of the gasses that escape nothing to do at all with moisture in the air, cold air coming in lowers the temp letting more unburnt gas escape.
[09:14:10] <gonzo_> woodgas stoves seem to be quite popular for camping. Very efficient of fuel and pretty smoke free when up to temp
[09:15:08] <gonzo_> they seem to work on an extra set of air holes above the main burner area, to mix with the exiting smoke/fumes and allow them to combust.
[09:15:25] <gonzo_> and the air is preheated as it goes
[09:15:58] <gonzo_> but given the small size of these little stoves, the burn time is a bit pathetic. So they are a bit of a gimic
[09:17:48] <IchGucksLive> hi
[09:18:24] <IchGucksLive> it is a nice sunny and nearly warm temp outsidei n germany i go to take a break MTB biking the forest
[09:18:35] <IchGucksLive> Steel rides the forest ;-)
[09:18:46] <IchGucksLive> no more cool milling
[09:19:05] <MacGalempsy> like in a freezer?
[09:19:18] <IchGucksLive> till the late evening
[09:19:24] <IchGucksLive> 16degC
[09:19:31] <IchGucksLive> brrrr
[09:19:58] <MacGalempsy> start the program and go inside
[09:20:31] <gregcnc> https://youtu.be/uVEqEv6BRNc?t=28s
[09:21:33] <MacGalempsy> cool milling!
[09:31:13] <gregcnc> even cooler machining https://youtu.be/GFOXbb7P2jc?t=1m21s
[09:38:00] <archivist> thermal shock, carbide hates that
[09:42:54] <gregcnc> I don't think tha'ts a problem here
[10:20:05] <archivist> room temp to - alot when they switch the coolant on
[10:21:16] <gregcnc> so what if it works and shows results?
[10:22:17] <archivist> I wonder if the initial cool is slower than it looked on the video, then should be ok
[10:23:09] <CaptHindsight> why does the wolf have blue eyes?
[10:24:09] <archivist> cold!
[10:25:29] <CaptHindsight> Doppelspindler! https://www.youtube.com/watch?v=IxBiWPZmcZI
[10:25:59] <gregcnc> 5 axis even
[10:26:32] <CaptHindsight> but no doppelgangerspindler for halloween
[10:30:38] <archivist> andypugh, look at https://www.youtube.com/watch?v=IxBiWPZmcZI 3 tool stores and two spindles
[10:30:48] <gregcnc> you could try a clown suit http://abc7.com/news/video-man-pistol-whips-scary-clown-prankster-in-california/1574665/
[10:35:55] <CaptHindsight> do clowns lives matter?
[10:37:06] <gregcnc> hmmm
[10:39:38] <CaptHindsight> gregcnc: maybe the reason those lathes from that school are still available is because they don't return calls or emails
[10:40:36] <gregcnc> makes it hard to sell that way
[11:07:32] <MacGalempsy> the dopplespindler needs a bigger tool changer
[11:07:45] <MacGalempsy> 100 probably isnt enough
[11:17:52] <CaptHindsight> what does this mean? " 50W LED - Actual 10W Power"
[11:18:24] <CaptHindsight> ^^ US seller on ebay
[11:20:45] <MacGalempsy> it may be a way to try and compare the light output of the bulb to a 50w incandesent
[11:26:48] <archivist> in the UK they have to state lumens these days
[11:27:43] <CaptHindsight> most of the legit sellers on ebay seem to do the same
[11:48:17] <djdelorie> I've started looking at lumens instead of watts at the local Home Depot too...
[11:50:20] <CaptHindsight> http://www.ebay.com/itm/LOT-OF-4-MITSUBISHI-HG-KR13-AC-SERVO-MOTORS-3AC-112V-0-8A-3000-R-MIN-250HZ-/311726889415 $150 for all 4
[11:50:42] <CaptHindsight> enough for a 4-axis servo router
[11:52:39] <djdelorie> now you just need a lot of 4 servo controllers, and a lot of 1 mesa board... ? ;-)
[11:59:17] <CaptHindsight> http://www.ebay.com/itm/302102367623 0.1um Renishaw heads, $300 for the pair
[12:08:26] <MacGalempsy> getting ready for the next build?
[12:09:39] <MacGalempsy> now that the furnace pour is finally setting, its back to finishing this box 3d printer.
[12:10:02] <MacGalempsy> stepper, no feedback
[12:18:01] <CaptHindsight> MacGalempsy: I'm usually in the middle of several builds. I'm just passing along the deals I come across
[12:21:14] <andypugh> archivist: We _probably_ don’t need to worry about LinuxCNC controlling that.
[12:22:51] <JT-Shop> I love it when my contact tells me my quote is a little low go figure it again
[12:24:13] <CaptHindsight> leave off a trailing zero?
[12:24:43] <andypugh> A tool-low quote can be taken to mean that they haven’t understood the question. Like asking a hand car-wash how much ro was a motorcycle, If they bid less that to wash a car, then they have never washed a bike..
[12:26:16] <JT-Shop> I don't think that much, but he wants me to add to the quote a pick up tool for the part
[12:28:51] <CaptHindsight> andypugh: just looking at your https://forum.linuxcnc.org/24-hal-components/22572-hal-power-laser#22961
[12:29:22] <andypugh> There isn’t as much there as I hoped when I started it.
[12:29:44] <andypugh> It might get another coat of looking at if I ever get a laser.
[12:30:17] <CaptHindsight> was for a XY system with linear positioners vs galvos?
[12:33:21] <CaptHindsight> I'm working on a galvo setup and will see how fast it can run without a DSP
[12:35:15] <CaptHindsight> it will most likely end up with different configs for cutting, etching and sintering
[12:36:49] <andypugh> CaptHindsight: I don’t think it would matter. The idea was to output X and Y. That would work for galvo or linear.
[12:38:09] <CaptHindsight> maybe it was another thread but did this modulate the laser power in proportion to feed rate?
[12:38:29] <CaptHindsight> to compensate for accel and decel
[12:41:44] <CaptHindsight> this looks like it just sets up raster scan
[12:43:10] <CaptHindsight> part of this project is to evaluate different schemes, raster vs vector, modulate laser power, etc
[12:48:17] <IchGucksLive> hi
[12:57:42] <IchGucksLive> going off as tommorrow is a hard workday just in to say hellow
[13:00:35] <Frank_30> lol bye
[13:15:23] <andypugh> CaptHindsight: The (partially) missing part is the bit that reads the image data from the shared-memory area that it has created.
[13:15:53] <andypugh> That part was intended to output a value dependent on the current pixel.
[13:22:58] <Tom_L> JT-Shop if you hired me, i could help you waste their money too...
[13:25:49] <JT-Shop> it will be a good change to pay taxes at the end of the year lol
[13:34:22] <CaptHindsight> was somebody looking for one of these? http://www.ebay.com/itm/EMCO-CNC-LATHE-MAIER-EMCOTURN-220-/222289003036
[13:37:35] <gregcnc> I want the chuck, if it was close I'd buy the whoel thing
[13:37:54] <CaptHindsight> gregcnc: pm
[13:38:07] <MacGalempsy> so the encoder on the 4th axis is 1250 cpr (5000 quad) anyone think 360crp would suffice?
[13:38:54] <MacGalempsy> .25 deg res
[13:38:55] <gregcnc> moar resolution
[13:39:09] <MacGalempsy> instead of 1/13th or so
[13:39:36] <gregcnc> ah that concept, yeah I set mine up to be 1/100th I think
[13:40:20] <MacGalempsy> so you have a 36000 quad encoder?
[13:40:53] <gregcnc> 400 on the motor with 90:1 reduction
[13:41:34] <MacGalempsy> the othe axii have 1:50000 tamagawa, which are around the same $
[13:41:51] <MacGalempsy> used of course
[13:43:24] <gregcnc> That machine has been listed in different cities on CL too.
[13:44:31] <CaptHindsight> http://www.ebay.com/itm/Weiss-WM180V-Metal-Lathe-Machine-with-DRO-2-Axis-12-X7-/282197678066 variable speed?
[13:45:18] <MacGalempsy> that weiss looks cool
[13:45:35] <CaptHindsight> take a closer look at the castings
[13:45:53] <CaptHindsight> like the molds were formed by hand out of clay :)
[13:46:22] <gregcnc> typical dc motor control
[13:46:59] <gregcnc> they really should just list those as lathe kits
[13:49:31] <CaptHindsight> yeah :)
[13:50:16] <CaptHindsight> you finish the alignment, drilling of lubricant holes, etc etc
[14:00:38] <CaptHindsight> http://www.ebay.com/itm/Denford-Mirac-Lathe-Table-Top-/231845842478 $2100 or best
[14:05:03] <MattyMatt> overpriced in UK that. you see the ones with the stepper driven turret for ~£900
[14:06:08] <CaptHindsight> it's an import here and it sounds smarter
[14:07:59] <MattyMatt> they all come from schools, even in US it seems :) musta been a UK teacher
[14:08:33] <MattyMatt> smuggled in in in his luggage
[14:08:55] <MattyMatt> or one back seat of his MG midget
[14:10:29] <MattyMatt> that might be an economical way to ship a machine, if a vehicle is flat rate
[14:14:30] <JT-Shopp> dang dropped a collet and it broke... now I have to figure out what style it is again
[14:15:41] <CaptHindsight> knocked a corner off a flute from a brand spanking new 1" cobalt end mill
[14:17:11] <MattyMatt> is it long enough to be worth regrinding?
[14:17:47] <CaptHindsight> yeah, it's a double end
[14:20:04] <CaptHindsight> >$200
[14:21:16] <MattyMatt> I had a notion to get an old giant endmill and turn it into a wood planer
[14:21:53] <MattyMatt> used giant ones go underpriced, and most on the wear will be on the end teeth
[14:25:39] <MattyMatt> and if there's a nail in the wood. it won't care so much
[14:30:17] <MattyMatt> http://www.ebay.co.uk/itm/Clarkson-Premium-Large-reground-long-series-HSS-End-Mill-/222283908113 wide enough for pallet wood
[14:32:00] <Jymmm> Um, what does this actually mean? "Operating Humidity: Non-condensing" I even read this but I'm still missing something... https://www.quora.com/What-does-non-condensing-mean-regarding-relative-humidity
[14:32:31] <MattyMatt> probably anything up to 100%
[14:32:54] <MattyMatt> if 100% warm air cools, the extra condenses out
[14:33:59] <MattyMatt> relative humidity is temp dependant
[14:34:32] <CaptHindsight> don't use it or not for use where there is condensation
[14:34:55] <Jymmm> Ok, I can see that. But non-conensing I'm not sure of. if it said "< 60% RH" I get it
[14:35:49] <Jymmm> CaptHindsight: Right, but I don't know what/when that would occure, what scanerio/situations, etc
[14:36:23] <MattyMatt> at constant temp, it'll never happen
[14:36:23] <CaptHindsight> rapid temp change from warm to cooler
[14:36:46] <Jymmm> Right now it's 54F @ 80% RH
[14:36:46] <CaptHindsight> the dew that forms on the meadow
[14:36:48] <Jymmm> MattyMatt: Ah
[14:37:03] <Jymmm> CaptHindsight: due to sunriase ?
[14:37:10] <Jymmm> sunrise*
[14:37:12] <JT-Shopp> Well I figured out they are Acrua-Flex collets, now to figure out what series they are
[14:37:29] <MattyMatt> sunrise evaporates the dew
[14:37:37] <MattyMatt> it's the cold of night that forms it
[14:38:00] <Jymmm> MattyMatt: from the warth the day before?
[14:38:05] <Jymmm> warmth*
[14:38:09] <MattyMatt> yep
[14:38:17] <CaptHindsight> humider air from the day that gets colder at night and scares the water out of it
[14:38:30] <Jymmm> CaptHindsight: lol
[14:38:48] <Jymmm> so non-condensing it really dont do rapid temp changes?
[14:39:10] <MattyMatt> basically. don't form clouds
[14:39:18] <CaptHindsight> warm dry to cold might not form condensation
[14:39:21] <gregcnc> it means the part shouldn't be below dew point temperature
[14:39:25] <MattyMatt> no kettles or gym bunnies
[14:40:07] <Jymmm> So if I heat the garage from 40F to 74F, dont open the damn door?
[14:40:27] <CaptHindsight> if it's humid or damp inside
[14:40:42] <Jymmm> CaptHindsight: what it's it's damp OUTSIDE?
[14:40:49] <Jymmm> if*
[14:41:12] <CaptHindsight> and colder inside or warmer inside?
[14:41:21] <Jymmm> warmer inside
[14:41:39] <gregcnc> I hate opening the garage in early spring when there is a warm humid day
[14:41:43] <CaptHindsight> won't condense until the inside is cooled enough
[14:41:48] <MattyMatt> if damp air which isn't fog blows into somewhere warm, it won't condense
[14:42:27] <Jymmm> Well, the issue is the dust collector exhausting the laser at 900CFM
[14:42:40] <djdelorie> I thought that too, one day. All that moisture condensed on cold pipes and dripped all over my machinery
[14:43:00] <gregcnc> Jymmm think iced drink in the summer
[14:43:23] <Jymmm> gregcnc: Yeah, that I get. it's the conditions that I'm unsure.
[14:43:24] <andypugh> JT-Shopp: Does this help? http://www.tools-n-gizmos.com/specs/AF_Collet.html
[14:43:35] <gregcnc> dew point
[14:44:38] <Jymmm> gregcnc: yeah, I'm still clueless. I judt don't want to heat the garage start a job on the laser, hit the dust collecoter and drop the temp so low that it condenses
[14:45:51] <gregcnc> condenses on what?
[14:45:59] <MattyMatt> the optics in the laser will be warm
[14:46:02] <JT-Shopp> andypugh: yes, thank you very much
[14:46:14] <Jymmm> I'm going to try and see if I can recirculate the exhaust thru a carbon filter back into the room, but that's really gong to depend on my availability of activated carbon pellets in this area.
[14:46:34] <Jymmm> MattyMatt: Sure, but at 900CFM, it cna cool them rapidly
[14:46:48] <JT-Shopp> 3/8" series
[14:46:55] <MattyMatt> if you blow wood smoke through activated charcoal, do you end up with more? :)
[14:47:13] <Jymmm> MattyMatt: Why yes, yes you do =)
[14:47:20] <djdelorie> perhaps you could look into getting an air dryer for the laser, to take out the humidify before it gets there?
[14:47:21] <CaptHindsight> more wood or charcoal?
[14:47:37] <Jymmm> CaptHindsight: yes
[14:48:02] <gregcnc> 900CFM air heat exchanger
[14:48:18] <djdelorie> or run the air over a cold radiator, so the humidity pre-condenses?
[14:48:29] <Jymmm> djdelorie: But I can do in that respect is raise the temp in the garage. and I'm working on that too ghetto style experiment.
[14:49:11] <Jymmm> Thats why I was talking about rocket stove/gassifiers last night.
[14:49:14] <enleth> does someone need a Bosch Z15-1A-240 SCR servo drive?
[14:49:40] <Jymmm> I REALLY odnt want a firebox IN the garage, but I may not have a choice.
[14:49:40] <djdelorie> I was just thinking car radiator + cold water = pre-condenser
[14:50:00] <djdelorie> it will also chill the air, better cooling ?
[14:50:09] * djdelorie is just throwing out random ideas
[14:50:17] <Jymmm> dont need cooling at 30F outside =)
[14:50:44] <gregcnc> jymmm is it very humid by you in the winter?
[14:50:53] <djdelorie> how much humidity do you expect at 30F ?
[14:50:57] <gregcnc> right
[14:51:49] <Jymmm> gregcnc: Right now, it's 54F @ 80% RH. How heavy the snowfall humidity is at that time I'm not sure.
[14:52:16] <gregcnc> heavy snow fall is same as rain, virtually 100%
[14:52:30] <Jymmm> Ok, then 100% I suppose
[14:52:34] <gregcnc> but air holds much less water at 30F vs 80F
[14:53:12] <djdelorie> they call it *relative* humidity for a reason ;-)
[14:53:33] <Jymmm> Well, I'm still undecided if I want to ehxhaust to the outside, which would draw in fresh from the outside via the garage as well
[14:54:01] <Jymmm> Also the whole firebox in the garage exhausting to the outside, bah
[14:54:02] <djdelorie> if the particulate rate is low enough, you might consider a fresh air exchanger system
[14:54:44] <djdelorie> a firebox can have an outside-air-supply to avoid sucking air into the general room space
[14:55:06] <Jymmm> djdelorie: It's not that, as much as a serious fire hazard
[14:55:22] <djdelorie> flash powder explosion?
[14:55:46] <Jymmm> tipping over, amber falls out, somethign falls on it, etc.
[14:56:15] <djdelorie> can't help you with that part ;-)
[14:56:39] <Jymmm> I only have 374 sq ft, putting a firebox in the garage will take up about 9% floor space with clearances.
[14:57:54] <gregcnc> if dumping 900CFM outside you need 36,000BTU to heat 30F air to 70F
[14:57:55] <Jymmm> Now, outside... I got craptons of space
[14:58:07] <Jymmm> gregcnc: 39K actually =)
[14:58:23] <Jymmm> per hour =)
[14:58:31] <djdelorie> to heat outside from 30F to 70F takes #Inf BTUs
[14:58:56] <Jymmm> gregcnc: I'm working on insulating the ceiling, just wont be for about 810 weeks
[14:59:06] <Jymmm> 8-10 weeks
[14:59:11] <gregcnc> some heat recovery would help temendously
[14:59:11] <Jymmm> maybe, hopefully
[15:00:53] <Jymmm> I've spent the whole summer sealing up holes/cracks in the walls, and even poured concrete and replace dryrotted structural beam. So I'm getting there, slowly =)
[15:01:49] <Jymmm> A neighbor works for insulation company, so he's going to hook me up once he recovers from knee surgery =)
[15:02:56] <Jymmm> at least the ciling for now.
[15:03:01] <Jymmm> ceiling*
[15:04:01] <Jymmm> gregcnc: Once I insulated (well), it drops to 9K BTU/hr. so hopefully at least doing the ceiling will be less than 18K
[15:04:01] <gregcnc> condensation though shouldn't be an issue unless the air is warmer than the equipment, so a warm spell if you let the building cool
[15:04:17] <gregcnc> so don't put a sauna or hot tub in the shop
[15:04:36] <Jymmm> Oh, it'll never be warmer that's for sure =)
[15:04:52] <Jymmm> gregcnc: awwwww =(
[15:05:19] <gregcnc> if you keep the shop warm, probably not
[15:06:02] <Jymmm> I have a propane heater now, but tha'ts mostly to suppliment, not "fully" heat.
[15:06:28] <gregcnc> if you don't heat it for days and it gets cold then you switch on the exhaust on a warm rainy day in the spring, it could
[15:08:16] <Jymmm> so when it's colder inside than out? Yeah, it does that in the spring, till I open the garage door for a while to balance out
[15:08:58] <gregcnc> during that time as the equipment warms, if it's humid enough, you'll get condensation
[15:08:58] <djdelorie> so how many other problems can be solved by "plan ahead" ? ;-)
[15:09:27] <Jymmm> djdelorie: Insert YOUR credit card here to find out --> [ ]
[15:09:55] <gregcnc> or you heat and warm things before exhausting or letting outside air in
[15:10:07] <djdelorie> my credit card is too awesome for your puny reader slot!
[15:10:26] <Jymmm> djdelorie: It's a chip read you whore!
[15:10:35] <gregcnc> same game you play with the window defroster in the car
[15:11:00] <djdelorie> my chips are sharp and hot, good luck reading them
[15:11:00] <gregcnc> except the car has dehumidier as a bonus
[15:11:16] <Jymmm> gregcnc: I am working on a firebox outside and ac radiator core inside to raise the temp +10 inside all night long hopefully
[15:11:30] <Jymmm> window AC cre that is
[15:11:31] <djdelorie> gregcnc: some cars use the A/C to defrost, on the idea that dry air will dry out the glass
[15:11:52] <gregcnc> all newer cars do
[15:13:17] <gregcnc> our dumb honda runs AC by default in auto mode
[15:14:36] <Jymmm> gregcnc: I have a newspaper rack that I'm wanting to turn into an outdoor firebox, that feeds a radiator core that I pulled form a window AC
[15:14:57] <Jymmm> that would be plumbed into the garage
[15:15:26] <Jymmm> very much like a coffee maker works with a lil check valve
[15:15:37] <Jymmm> open loop, so thers' no boiler effect
[15:17:19] <gregcnc> yeah will be cool to see how that works out.
[15:24:48] <Jymmm> gregcnc: Yeah, me too =) I found a perlite/mortar mixture so I can pout custom fit firebricks for the newspaper rack
[15:24:59] <Jymmm> ^recipe
[15:25:47] <Jymmm> Not sure if I want to use "regular" sized perlite (#2), or get some chunky perlite (#3) size.
[15:27:13] <Jymmm> ...since the mortar is only to hold/keep the perlite into it's designated shape.
[15:27:31] <Jymmm> chunky perlite == less mortar?
[15:28:47] <Jymmm> #3 = 1/8 to 5/8 granules
[15:29:09] <Jymmm> #2 = 1/16 - 5/8 granules
[15:32:22] <Jymmm> Nice, I just called and I can get 4CF bag of #2 for $13.99
[15:39:09] <andypugh> Jymmm: I think that bigger marticles mean more matrix.
[15:39:20] <andypugh> (particles)
[15:39:48] <andypugh> Though only in finite-sized containers
[15:40:12] * JT-Shopp thinks marticles is a Martian particle
[15:40:13] <andypugh> Otherwise the packing ratio is independent of scale.
[15:40:20] <andypugh> (I think)
[16:05:24] <Jymmm> andypugh: And in dumbass speak that would be? Bigger better? smaller better? doesn't really matter?
[16:05:51] <andypugh> Makes no difference at all
[16:06:26] <Jymmm> andypugh: wouldn't smaller mean more mortar to the mix?
[16:09:36] <andypugh> No, because you would have more of the smaller ones. With smaller gaps between them.
[16:09:55] <Jymmm> hmmm, ok
[16:10:06] <andypugh> Take a bucket of balls, add enough water to fill the space.
[16:10:21] <andypugh> Now make the bucket 4x bigger. You use 4x the water.
[16:10:50] <Tom_L> Jymmm you tryin to slow cook yourself this winter?
[16:11:03] <andypugh> Now shrink the bucket and the balls back to the same size. Same amount of water, 4x smaller balls.
[16:11:51] <Jymmm> 4Cf of the chunky perlite is double the price of the regular stuff, so I'll go with the regular stuff if theres no benefit
[16:11:51] <Tom_L> i wonder if bioballs would work like you use in fishtank filters
[16:12:18] <Jymmm> Tom_L: More like not burn down anything =)
[16:12:39] <Jymmm> Tom_L: I can get 4CF of regular sized perlite for $14, so I think I'm good there.
[16:13:40] <Tom_L> i think you'll find this thing more efficient than you think
[16:13:44] <Tom_L> rue did
[16:14:22] <Jymmm> Tom_L: Which "thing" are you speaking of? There are lots of components to all this =)
[16:14:27] <Tom_L> is this direct or radiated heat from water?
[16:15:17] <Jymmm> newspaperfirebox outside with SS coil plumber to window AC radiator core inside the garage
[16:15:25] <Jymmm> plumbed*
[16:15:42] <Tom_L> using antifreeze water?
[16:16:05] <Jymmm> just water for now, maybe glycol down the road if it pans out.
[16:16:14] <Tom_L> you should
[16:16:42] <Tom_L> his froze up on him once iirc
[16:16:55] <Jymmm> this is ALL an experiment for now, and I'm doing it on the cheap/free/what I already have and only buying whats REQUIRED.
[16:17:10] <Tom_L> so did he
[16:17:34] <Jymmm> Tom_L: but he's doing a closed loop, I'm doing an open loop
[16:17:41] <Tom_L> did you look thru his pics?
[16:17:49] <Tom_L> old watertanks converted etc
[16:18:11] <Jymmm> Tom_L: All the hundreds of them, but like I said, with nocontext/notes/footnotes, they are not helpful.
[16:23:10] <Jymmm> Tom_L: ... as I don't know the story (success/failure) behind them
[16:25:51] <Tom_L> ask him
[16:44:35] <Deejay> gn8
[16:55:23] <Nick-Shop> JT -you around?
[16:56:12] <JT-Shopp> barely
[16:56:53] <JT-Shopp> brb
[16:57:27] <Nick-Shop> Hardinge-CR-13 is there anymore than supplying voltage to it?
[17:02:39] <JT-Shopp> nope, put 24 to + and 0 to - and the light comes one
[17:02:42] <JT-Shopp> if it works
[17:06:21] <Nick-Shop> just wondering if there was deeper wiring to deal with
[17:08:20] <Nick-Shop> 7i37 - how do I make an input to an output or is there a larger card I can use with the 5i23
[17:14:38] <JT-Shopp> iirc an opto22 will plug into a 50 pin header
[17:15:20] <JT-Shopp> 7i37TA is the only card I have for I/O direct to a 5i2x card
[17:18:10] <Nick-Shop> 7i37TA is what I have now - Running out of i/o's
[17:19:12] <JT-Shopp> 5i23 has two or 3 50pin headers I forget?
[17:19:43] <Nick-Shop> has 3 headers
[17:19:55] <JT-Shopp> they all full?
[17:21:01] <Nick-Shop> no a 7i49 and a 7i37TA are in there now
[17:21:21] <JT-Shopp> you can add another 7i37TA
[17:21:35] <JT-Shopp> that's what I have in the CHNC
[17:22:11] <Nick-Shop> is that cost effective or does mesa have 1 larger i/o card?
[17:23:11] <JT-Shopp> that's the only one I know of to plug directly into the 50 pin header
[17:24:16] <Nick-Shop> ok - guess I'll have to spring - can I change input to an output?
[17:24:28] <JT-Shopp> not that I know of
[17:27:27] * JT-Shop has to make a choice between juicy lucy's, korean, or bacon burgers
[17:28:25] <MattyMatt> juicy lucy's korean bacon burgers. obvs
[17:28:59] <MattyMatt> korean bacon = good chow?
[17:30:35] <JT-Shop> http://gnipsel.com/recipes/beef/korean-hamburgers.html
[17:31:16] <MattyMatt> pit bull beef
[17:32:02] <MattyMatt> I discovered sesame ramen yesterday. fabulous
[17:32:16] <JT-Shop> home made?
[17:32:50] <MattyMatt> nope just a packet
[17:33:24] <MattyMatt> has the usual sachet of soup powder, and a little sachet of real sesame oil
[17:34:11] <MattyMatt> and I add a spoonful of PB just beacuse
[17:34:40] <MattyMatt> I'm going back to the store to clear the shelf tomorrow
[17:38:04] <Jymmm> MattyMatt: PB = Peanut Butter
[18:42:47] <enleth> pcw_home: is it recommended to add a flyback diode to ENAx+/- (analog drive enable) lines on 7i77 that drive a relay?
[18:43:26] <enleth> the relays are OMRON LY4, 24V, 70mA, 1.4-2.9H
[18:44:14] <enleth> wait, those are 50mA max, not 100mA, so it's a moot point anyway
[18:44:25] <enleth> "those" being the ENA outputs
[18:45:02] <pcw_mesa> Yes those OPTOs are not good for 70MA
[18:45:33] <pcw_mesa> can you drive the servo enabled directly with the OPTO?
[18:45:39] <pcw_mesa> enables
[18:46:51] <enleth> there's a bunch of stuff in the way - axis brakes need to be released, motor contactor closed, handwheels interlocked, etc.
[18:47:27] <enleth> the original Heidenhain control had relay outputs, so it wasn't a problem that the axis enable line for the machine as a whole is a relay itself
[18:47:54] <enleth> so I guess I'll just take the Heidenhain relay board and route the signal through that
[18:48:35] <pcw_mesa> probably better to use a 7I77 digital output for driving a 70 mA relay
[18:49:39] <enleth> well, I *can* use the old board as a proxy
[18:49:55] <enleth> and not waste a perfectly good output port
[18:50:33] <enleth> OTOH I might want to enable the axes individually, which the ENA0-4 outputs can't do if I understand the manual correctly
[18:51:07] <enleth> is that correct?
[18:52:45] <pcw_mesa> Yes the are logically commoned
[18:53:35] <pcw_mesa> (as are linuxcncs axis enables so its rarely any disadvantage)
[18:55:09] <enleth> ok, I don't think I have any real use cases for that as handwheels are interlocked in hardware anyway
[19:00:55] <enleth> it's not going to let me engage a handwheel on one axis while having a servo for another connected to the drive - without a major rewire I'm not willing to do
[19:01:16] <enleth> and there's no valid use for that anyway
[19:06:35] <MarkusBec> pcw_mesa: did you have any advice how to use an old 7i43 with a pci/pcie card
[19:07:05] <pcw_mesa> PCI/PCIE parallel card?
[19:07:43] <MarkusBec> yes
[19:08:41] <pcw_mesa> I think the main thing is to avoid MOSChip/NetMOS chipsets on the parallel card
[19:08:46] <MarkusBec> i have a mcs98651 mcs9815 and a ch3821 here
[19:08:56] <MarkusBec> hm ok
[19:09:03] <MarkusBec> 2 moschip
[19:09:18] <MarkusBec> und 1 properbly total useles china card
[19:09:36] <pcw_mesa> Actually the CH382 is the most likely candidate
[19:10:00] <MarkusBec> did you know how to switch on epp mode?
[19:10:07] <pcw_mesa> (since MOSChip PP chisp dont implement EPP correctly)
[19:10:23] <MarkusBec> at the ch382
[19:11:05] <enleth> pcw_home: BTW, it would be rather helpful if the field IO connectors were a different color for inputs and outputs. I had to mark them to be able to identify them with the board mounted inside the control enclosure
[19:11:09] <pcw_mesa> I would assume its the standard IEE1284 way so the driver might just work if you get the base address right
[19:12:24] <enleth> identify them quickly, to be exact
[19:14:41] <pcw_mesa> as long as you dont care about them not matching the headers we can supply orange plugs
[19:16:21] <enleth> an exact part number for those would be enough, I'm sure Farnell carries them
[19:16:41] <enleth> I haven't been looking for it very hard but haven't stumbled on it either in the manual
[19:17:23] <pcw_mesa> its just a 3.5mm pitch side entry pluggable screw terminal block
[19:18:02] <enleth> with a specific way of keying that is not an industry standard, as far as I can tell
[19:23:50] <enleth> okay, got it, I hope it fits if it looks more or less the same
[19:30:13] <nicless> I have a pair of Advanced Motion Controls Digiflex Digital Servo Drives that I stripped off a machine along with it`s 3p Sanyo Denki motors 1kW. The controller pc had pci card SynqNet interface to Digiflex Drives but no hard drive:[. I don`t have MEI motion apps. Ill may query them to see if something is downloadable. But figured I`d take a shot here to see if anyone had any SynqNet know how. The drives are in a box here
[19:30:14] <nicless> somewhere but if I recall correct the didnt have rs232 port. Price would be right [$0] if I could get them to move.
[19:33:06] <MarkusBec> pcw_mesa: did you have known good pci/pcie lpt card
[19:37:46] <pcw_mesa> Oxford Semi are known to work I suspect the ch382 does also
[19:38:36] <MarkusBec> i am downloading the latest wheezy linuxcnc releas and will try it
[19:38:41] <pcw_mesa> (motherboard ports are much less trouble in general though)
[19:38:43] <pcw_mesa> Ill buy a ch382 and test here when I get a chance
[19:38:49] <pcw_mesa> bbl Dinner!
[19:38:50] <MarkusBec> the old ubunut version dont work
[19:39:01] <MarkusBec> with 2.6 kernel
[19:39:47] <MarkusBec> and the self build have some wired behavior
[20:50:12] <Frank_30> how much time would you estimate for someone to learn linuxcnc from scratch and get to do work on a router?
[20:51:10] <Frank_30> like 2.5D stuff
[20:51:58] <malcom2073_> Between a day, and a year
[21:01:00] <Denkishi> OK, so is there a technical term for a relief slot for a part that clamps onto a bar?
[21:14:06] <Tom_L> keyway
[21:14:21] <Tom_L> spline
[21:14:24] <Tom_L> be more specific
[21:24:23] <Denkishi> E.g. I have a part, 1x1x6. .825 in from either end I make a .5 reamed hole. flip the part, drill and tap for a 1/4-20 shcp, Then the "spilt" that would create the relief and allow the part to "clamp".
[21:24:50] <renesis> draw pick
[21:25:07] * Denkishi should've prefaced that drinks have been had and he is just curious :P
[21:25:35] <Denkishi> Ugh, damn you renesis lol. sec
[21:26:20] <renesis> ooh
[21:26:54] <renesis> haha i dunno, slotted block clamp?
[21:28:18] <renesis> https://www.amazon.com/Scooter-Clamps-Proto-Half-Knuckle/dp/B01LL1B7U8/
[21:28:31] <renesis> like that?
[21:28:47] <renesis> well, like conceptually
[21:28:55] <Denkishi> jes
[21:29:04] <Denkishi> exacrty
[21:29:18] <renesis> slotted clamp is kind of the generic term, i dont know if it has a formal name
[21:29:36] <renesis> if you say slotted clamp most people are going to assume you mean something like that
[21:30:00] <Denkishi> what I am actually looking for is a decent set of horizontal saws for the bridgeport
[21:31:02] <renesis> like to mount on the headstock to saw things?
[21:31:05] <renesis> heh
[21:31:18] <renesis> what is horizontal saws for a mill
[21:32:50] <Denkishi> Well the way I figure is trying to cut the slot on a band saw is sloppy
[21:33:54] <Tom_L> broach
[21:34:06] <Tom_L> or slitting saw
[21:35:55] <Denkishi> slitting!
[21:36:07] * Denkishi high fives Tom_L
[21:39:13] <Denkishi> It's amazing how much easier google becomes when you have the proper terms :/
[21:39:31] <Tom_L> uh huh
