[00:12:58] <ssi> PCW: never mind I found the bug! :D
[02:01:47] <archivist> rofl is a bracket with slots worth much http://www.ebay.co.uk/itm/Renishaw-MCR20-Probe-changer-TP20-/121806762270

[06:51:27] <logger[mah]> Tom_itx: Log stored at http://linuxcnc.mah.priv.at/irc/%23linuxcnc/2015-11-05.html
[06:52:13] <jthornton> morning Tom_itx
[06:52:49] <Tom_itx> morning
[06:53:00] <Tom_itx> client quit.. dunno why
[06:53:28] <Tom_itx> muggy day here
[06:53:53] <Tom_itx> already 65°F
[07:02:38] <jthornton> 60f and 96% humidity here
[07:02:56] <Tom_itx> how's the translator coming along?
[07:02:59] <jthornton> got to get 2 pcs of siding up and put my stuff away this morning before the rains come
[07:03:08] <jthornton> I'm having fun programing it
[07:03:16] <Tom_itx> that's the main thing
[07:03:22] <jthornton> learning a bunch of new stuff in python and golang
[07:03:37] <Tom_itx> i should learn another language
[07:03:54] <Tom_itx> not too good at any of em
[07:04:19] <jthornton> golang is cool and fast and a short learning curve after you get over the initial hump
[07:04:26] <Tom_itx> fixed a bug in my 25yr old database program last night
[07:04:42] <Tom_itx> i do an export so i can put it on the phone
[07:05:10] <Tom_itx> is it like c?
[07:06:15] <jthornton> it's C like
[07:09:11] <Tom_itx> does it have low level functions like fread fwrite etc?
[07:10:23] <jthornton> https://golang.org/pkg/bufio/
[07:10:35] <jthornton> that's buffered I/O
[07:10:49] <jthornton> I forget what fread fwrite does
[07:11:06] <Tom_itx> reads from / to file
[07:11:23] <Tom_itx> fcreate, fopen, fread, fwrite
[07:12:14] <Tom_itx> you can read from back or front of file
[07:12:59] <jthornton> yea, I'm sure it has all that
[07:13:30] <jthornton> https://gobyexample.com/reading-files
[07:14:08] <Tom_itx> more like c++
[07:14:19] <Tom_itx> with objects
[07:15:46] <Tom_itx> looks simple enough but would take some getting used to
[07:16:34] <jthornton> yea, once you get over the initial hump it's fast and easy
[07:18:08] <Tom_itx> defer is something new to me
[07:25:58] <jthornton> I just figured out how to run my go program from my python GUI and get the stdout and stderr back
[07:28:55] <jthornton> golang also has channels https://tour.golang.org/concurrency/2
[07:29:19] <jthornton> https://gobyexample.com/channels
[07:29:26] <Tom_itx> why did you choose go?
[07:29:43] <jthornton> ssi, told me about it
[07:30:00] <jthornton> https://golang.org/doc/effective_go.html#concurrency
[07:34:13] <jthornton> now I need to make go read my python generated ini file
[08:52:54] <ssi> Tom_itx: go *is* C
[08:53:13] <ssi> Tom_itx: it's C if C were written today
[08:59:37] <FinboySlick> Nah. C lets you be mean to other people.
[09:00:30] <FinboySlick> http://developers.slashdot.org/story/15/11/02/0650200/could-go-communitys-threat-of-public-shaming-lifetime-bans-make-go-a-no-go
[09:03:22] <JT-Shop> well the rain has arrived here
[09:07:33] <archivist> I get amused at how people become language fanboys and haters
[09:07:59] <malcom2073> I get amused at how people become anything fanboys and haters
[09:11:08] <Jymmm> malcom2073: Which one are you? =)
[09:11:31] <malcom2073> I strive to avoid mindlessly loving or hating anything :P
[09:11:50] <Jymmm> Ok, both it is!
[09:12:52] <CaptHindsight> https://en.wikipedia.org/wiki/Anosognosia
[09:14:29] * Jymmm lol @ CaptHindsight
[09:15:05] <Jymmm> CaptHindsight: I didn't realize malcom2073 was Egytian (or Greek)
[09:15:18] <malcom2073> Hah
[09:15:37] <malcom2073> If I'm an example of that, you're an example of dunning kruger :)
[09:16:11] <malcom2073> I wasn't aware having an open mind was a disability, fi that is so, then by all means you're correct
[09:16:46] <malcom2073> I do indeed reject and deny that disability :)
[09:16:56] <malcom2073> *that as a disability*
[09:18:46] <malcom2073> Though codes of conducts are quite amusing
[09:19:11] <archivist> overly PC
[09:19:20] <malcom2073> To a fault
[09:19:39] <archivist> cannot call a spade a spade
[09:19:50] <tiwake> screw being politically correct.
[09:20:04] <malcom2073> I understand the intent, but Coc's only work in a perfect world, where you wouldn't need it anyway
[09:21:56] <malcom2073> The comments on that slashdot are funny
[09:24:53] <JT-Shop> I need to generate some text into straight G code
[09:25:36] <JT-Shop> for engraving on my BP VMC that only speaks DX-32 G code ie. G1 G2 G3
[09:28:00] <malcom2073> Any reason why you can't use your favorite 3d modeling program to draw text, export to DXF, then dxf2gcode to output?
[09:28:24] <JT-Shop> why yes I can, didn't think of that lol
[09:28:45] <malcom2073> I've been doing that for playing around with engraving lately
[09:29:02] <malcom2073> Would be awesome if there was a dedicated text to gcode program, I'm sure some such thing exists somewhere
[09:30:45] <JT-Shop> there is a few that I know of
[09:30:52] <JT-Shop> http://www.mgware.co.uk/
[09:31:01] <JT-Shop> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple_LinuxCNC_G-Code_Generators#Text_Engraving_Software
[09:31:11] <Jymmm> This aint good enough for ya JT-Shop??? http://timeguy.com/cradek/truetype
[09:31:23] <JT-Shop> it outputs nurbs
[09:31:38] <JT-Shop> which is fantastic on my LinuxCNC machines
[09:34:35] <Jymmm> WHAT?! Not all your machines are LinuxCNC?!?!?! lmao
[09:34:58] <JT-Shop> what is funny about that?
[09:35:14] <cradek> JT-Shop: old versions of truetype-tracer used arcs
[09:35:36] <JT-Shop> oh I forgot, thanks cradek
[09:35:39] <cradek> you should be able to get a suitable version from git.timeguy.com
[09:47:34] <membiblio> What do you all call the vacuum system that removes detritus from a cnc router work area? Detritus Vac? Something else vac? :)
[09:48:22] <JT-Shop> I know I should be able to but I'm not figuring out how to get a suitable version
[09:48:25] <JT-Shop> git clone http://timeguy.com/gitweb/truetype-tracer ttt
[09:48:38] <JT-Shop> http://timeguy.com/gitweb/truetype-tracer/info/refs not valid: is this a git repository?
[09:51:38] <cradek> JT-Shop: go to git.timeguy.com; click truetype-tracer.git; use the URL it states at the top there
[09:51:46] <JT-Shop> ok
[09:51:47] <cradek> it's a git:// not a http://
[09:52:04] <JT-Shop> ok
[09:52:31] <JT-Shop> http://timeguy.com/gitweb?p=truetype-tracer.git;a=summary
[09:54:39] <cradek> heh sorry, on the page itself, it says "URL" and that is the url you should use to clone it
[09:54:51] <cradek> under the description
[09:55:18] <JT-Shop> lol I see it now
[09:55:24] <archivist> I remember when it was a zip file :)
[09:55:28] <JT-Shop> I finally guessed it
[09:56:16] <cradek> archivist: in gitweb you can poke "snapshot" and get a tgz of any ref
[09:57:16] <archivist> cradek, I started out with a copy in 2008 sometime
[09:57:44] <archivist> added part of the code to do v form engraving
[10:11:30] <cradek> did you get it to work?
[10:12:09] <_methods> CaptHindsight: when did you need the injection molder by?
[10:18:06] <CaptHindsight> _methods: looking for a small one, ASAP, ~end of the month
[10:19:08] <_methods> pm
[10:19:17] <CaptHindsight> not enough time for a complete overhaul, but maybe just a few days of work
[10:22:17] <ssi> https://twitter.com/vine/status/662278289772400641
[10:27:21] <_methods> cats....
[10:27:57] <Sync> old
[10:29:03] * Sync hides
[10:29:06] <ssi> :)
[10:29:12] <ssi> Sync: my code worked! my code worked!
[10:29:21] <Sync> woop woop
[10:30:24] <JT-Shop> ssi, what are you coding?
[10:30:46] <ssi> JT-Shop: smartserial support for the stmbl servo drive
[10:31:09] <JT-Shop> cool
[10:51:43] <archivist> cradek, I got the the hard part and life got in the way so no :(
[10:54:19] <mymill15> Questio i changed the PC now it got 2Core do i need to isolate one on Mesacarduse or only on parport
[10:59:50] <pcw_home> In general if you use hardware stepgens or a servo system, latency is not much of an issue so isolating a CPU for
[10:59:52] <pcw_home> LinuxCNC just makes the system slower and has no particular advantage
[12:03:01] <jdh> how common is 240vac on one leg of a drive and gnd on the other? (in .us)
[12:13:00] <JT-Shop> I've seen 277 on one leg with ground before... I don't recall ever seeing 240v / gnd on anything here
[12:15:45] <CaptHindsight> 277VAC Wye is common for lighting circuits since the 277 is one leg of a 277/480VAC system
[12:16:07] <archivist> neutral and ground are very different over here
[12:17:14] <ssi> pcw_home: is it feasible to use linuxcnc to control a position mode drive that uses motor angle as its command?
[12:17:14] <CaptHindsight> in the US 240VAC is on a Delta and is across 2 poles, and the neutral in a center tap of only one coil giving 120VAC from neutral to 2 poles
[12:17:35] <archivist> although joined in places, so over here we see up to 6v offset ish
[12:18:48] <CaptHindsight> archivist: I think he meant neutral vs ground anyway. They are bonded at only one point here within a structure
[12:19:08] <jdh> this is 240 from line to frame.
[12:19:13] <archivist> here they are bonded at the substation
[12:19:36] <CaptHindsight> archivist: we can see a difference here as well depending on the length of the neutral
[12:19:39] <archivist> which is why we see the offset to local ground
[12:19:55] <jdh> it comes via 480->120->240
[12:21:34] <CaptHindsight> http://blog.allshookup.org/wp-content/uploads/2008/04/us_power_services.pdf
[12:32:00] <CaptHindsight> jdh: you can get 240Vac single phase from delta by grounding one pole of the transformer but it's very uncommon
[12:32:39] <CaptHindsight> corner grounded delta
[12:34:37] <CaptHindsight> jdh: http://imagebin.ca/v/2LX3UCyvkB4v
[12:37:11] <CaptHindsight> jdh: vs center tapped delta that you find in older cities and industrial locations http://imagebin.ca/v/2LX44QSCngPG
[12:38:42] <CaptHindsight> archivist: looks like the only difference here is that we bond the neutral at the substation, and at the pole where the transformer is and at the service entrance
[12:39:58] <CaptHindsight> we bond the neutral on the secondary side of the transformer on the pole to ground with a rod at the pole
[12:41:01] <CaptHindsight> and then every service on the secondary bonds the neutral from that pole to ground at the entrance
[12:41:40] <CaptHindsight> some cities require a ground rod at the meter as well as a ground wire to a cold water pipe inside
[12:45:57] <archivist> we have a house ground rod
[12:46:55] <CaptHindsight> this is what they argue about over at the fire and safety conventions
[12:47:37] <archivist> the earth boding became silly at one edition of the wiring regs, "all exposed metal shall be grounded" so chapel hat pegs all needed bonding!
[12:47:44] * Jymmm lmao @ "cold water pipe"
[12:48:11] <CaptHindsight> how many grounds and where, conduit vs romex, GFCI vs AFCI
[12:48:13] <Tom_itx> use the gas pipe
[12:48:23] <_methods> lol
[12:48:26] <_methods> bewm
[12:48:28] <Jymmm> Tom_itx: the plastic or metal ?
[12:48:31] <archivist> the cold water and gas were bonded and available as your ground but then plastic pipes made that silly too
[12:48:32] <CaptHindsight> heh, plastic
[12:48:35] <Tom_itx> either one is fine by me
[12:48:47] <Tom_itx> i'm far enough away...
[12:48:54] <_methods> hehe
[12:48:55] <Jymmm> Tom_itx++
[12:49:32] <Tom_itx> if you're gonna have a ground rod make sure it's deep enough to do some good
[12:49:53] <Tom_itx> mine is at least 8-10 ft down
[12:50:01] <Jymmm> only one?
[12:50:03] <CaptHindsight> Jymmm: http://www.doityourself.com/forum/attachments/electrical-ac-dc/48333d1427052484-grounding-system-single-grounding-wire-meter-doubling-back-rods-ground.jpg required in case you water service gets disconnected
[12:50:07] <Tom_itx> the main one
[12:51:08] <Jymmm> CaptHindsight: lol, grounding PVC pipe =)
[12:51:25] <Tom_itx> they took the neighbor's gas meter the other day...
[12:51:45] <CaptHindsight> that'll teach em
[12:52:06] <Tom_itx> it's a rental and i expect her to get evicted soon
[12:52:18] <PCW> https://www.youtube.com/watch?v=GjxEINFTUug
[12:52:22] <Jymmm> Who's "they" ?
[12:52:35] <Tom_itx> the gas co
[12:52:40] <Jymmm> ah
[12:52:42] <CaptHindsight> gas meter thieves
[12:52:48] <Tom_itx> yeah
[12:52:53] <CaptHindsight> really dumb
[12:53:14] <Tom_itx> if i wanted gas, i'd patch a pipe between em and never say a word
[12:53:21] <Jymmm> PCW: WHAT THE FUCK is that??????
[12:53:29] <_methods> 1ft deep isn't much of a ground
[12:53:52] <Tom_itx> cable & phone use some silly 3' rods
[12:54:41] <CaptHindsight> Chicago is 1/2 dia x 8 ft copper
[12:54:59] <Tom_itx> clad
[12:55:02] <_methods> so that's why you don't do parallel ground rods lol
[12:55:17] <Jymmm> HAHAHA "They test just before fishing as it gets the worms out of the ground" GOTTA LOVE IT!!!
[12:55:18] <archivist> stuffed if you are on bedrock :)
[12:56:07] <CaptHindsight> archivist: an option is a copper grid with salted earth
[12:56:42] <Jymmm> Method A) https://www.youtube.com/watch?v=vvCZvNj8H30
[12:56:56] <Tom_itx> that's about what it looked like around the base of the tree here that got hit recently
[12:57:10] <Jymmm> Method B) https://www.youtube.com/watch?v=htprIppsx70
[12:57:22] <Tom_itx> looked like they roto tilled the ground
[12:58:31] <Tom_itx> water's alot easier
[12:58:39] <Tom_itx> i just used the rod itself and a cup of water
[12:58:57] <JT-Shop> ssi, is there a way to build a go program online and save the executable to a github account?
[12:59:18] <malcom2073> JT-Shop: You mean automated like?
[12:59:39] <malcom2073> You could set up a build server, build it and auto-upload to github as a "release"
[13:01:01] <Jymmm> Tom_itx: I'm thinking 12ga ram set ground rod installation =)
[13:01:05] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/temp/pipe/pipe1.jpg
[13:01:07] <Tom_itx> haha
[13:01:22] <CaptHindsight> https://www.youtube.com/watch?v=V4vzBiDmzIA how not to install a ground rod
[13:02:11] <JT-Shop> upload is what I'm not wanting to do... very limited bandwidth
[13:02:33] <_methods> use a vps
[13:02:37] <Tom_itx> CaptHindsight, they're retired RR workers
[13:02:37] <_methods> do all your building on that
[13:02:49] <_methods> then you won't be using your bandwidht
[13:02:53] <malcom2073> JT-Shop: Spend $5 for a server elsewhere?
[13:03:13] <JT-Shop> two options what I got and huges net and that's worse
[13:03:15] <_methods> digital ocean
[13:03:19] <JT-Shop> hughes
[13:03:23] <Tom_itx> i could set up a space on mine if you want some obscure web address like mine is :D
[13:03:39] <Tom_itx> it's free
[13:04:03] <JT-Shop> I have unlimited space on my web host...
[13:04:05] <ssi> JT-Shop: yeah you want a continuous integration service
[13:04:08] <ssi> JT-Shop: like codeship maybe
[13:04:12] <SpeedEvil> http://imgur.com/gallery/dI8xnCj the future of domestic appliances
[13:04:27] <Tom_itx> JT-Shop, does it go against your bandwidth?
[13:04:33] <Tom_itx> locally
[13:04:42] <ssi> JT-Shop: https://codeship.com
[13:04:46] <JT-Shop> no, only uploads and downloads are on sat
[13:04:49] <ssi> they probably have go builders
[13:05:15] <archivist> do everything at home, 0 bandwidth used
[13:05:33] <JT-Shop> then I can't share
[13:06:03] <archivist> the amount you need to share is a very small upload
[13:06:54] <JT-Shop> I'm already sharing the code but the executable is 2mb
[13:07:31] <Tom_itx> that's quite a bit of overhead for an exe
[13:07:38] <Tom_itx> for what it does
[13:07:44] <Sync> zeeshan-lab: need halp
[13:07:53] <Tom_itx> does it need to pull in all the libs etc that it's pulling in?
[13:08:00] <ssi> Tom_itx: golang binaries are statically linked
[13:17:26] <CaptHindsight> SpeedEvil: and you'll like it as well
[13:18:43] <JT-Shop> Tom_itx, probably not but I've not explored how to just import fmt.Println yet

[13:44:14] <_methods> unpowered exoskeleton
[13:57:10] * JT-Shop now knows what a $50 1/4-20 tap looks like... wish I had the special drill for it
[14:18:20] <CaptHindsight> _methods: how many millions did they spend on paper and how many patents cover that now?
[14:20:49] <_methods> hah who knows
[14:21:05] <_methods> it's all taxpayer money so who cares
[14:21:43] <CaptHindsight> http://www.google.com/patents/US20080009771
[14:42:57] <CaptHindsight> http://www.ebay.com/itm/matsuura-ra2f/151870846045 $1k but no mention of a reserve price
[14:46:19] <XXCoder> not sure if that was goverment research
[14:50:29] <_methods> i just watched a 2001 fadal 4020 vmc go for $3k lol
[14:50:39] <PetefromTn_> jeez
[14:50:42] <_methods> yeah
[14:50:50] <_methods> made me want to cry
[14:51:05] <PetefromTn_> thats a great machine in my view
[14:51:10] <_methods> it was untouched too
[14:51:12] <XXCoder> fadal isnt too bad
[14:51:34] <_methods> fadal sux
[14:51:39] <_methods> that's why they went out of business
[14:51:42] <_methods> but for $3k
[14:51:44] <_methods> i can forgive lol
[14:51:49] <XXCoder> _methods: theyre back
[14:52:02] <_methods> so they can go under again lol
[14:52:02] <XXCoder> also, its old one that isnt too bad, newer one suck
[14:52:08] <Jymmm> _methods: For you, $30,000 =)
[14:52:11] <XXCoder> and new one is absed on old one
[14:52:19] <XXCoder> much more modern software but yeah
[14:53:31] <_methods> the funny part is the harding hlv-h at the auction went for $16k
[14:53:43] <_methods> 5x as much as a 4020 cnc lol
[14:53:57] <_methods> for a manual lathe
[14:54:23] <ssi> jesus hlv-h is a nice lathe but it's certainly not a 16k lathe
[14:54:28] <_methods> hell no
[14:54:35] <_methods> it was in immaculate shape though
[14:54:42] <_methods> but not $16k shape
[14:54:48] <ssi> a couple years ago I did a linuxcnc retrofit for a customer
[14:54:50] <_methods> one weird auction
[14:54:57] <ssi> on an atrump knee mill that had a dead centroid control
[14:55:00] <_methods> i got burnt on the haas tm-1's
[14:55:06] <_methods> guy got choice on both
[14:55:09] <ssi> they quit using that machine, and I kept trying to buy it from them
[14:55:11] <_methods> $8750
[14:55:15] <ssi> but they wouldn't sell it to me
[14:55:16] <_methods> he stole both of them
[14:55:32] <ssi> I got a phone call today, some guy took it from them as payment on a bill they were never gonna pay
[14:55:37] <_methods> oh man
[14:55:38] <ssi> he wants 3500-4k for it
[14:55:39] <_methods> that sux
[14:55:40] <ssi> I told him 2500
[14:55:53] <ssi> might end up trying to get it from him, maybe I can get him to meet me at 3
[14:56:18] <ssi> it's not the greatest machine in the world, but it's a relatively well done 50" bridgeport style knee mill with decently powerful servos
[14:56:25] <ssi> and it's already got a good linuxcnc conversion
[14:56:30] <XXCoder> nice
[14:57:05] <ssi> plus all that pneumatic material handling crap I added for them
[15:12:25] <Tom_itx> JT-Shop, what's special about a 1/4 20 tap that makes it cost that much? double lead, lefthand, both?
[15:13:20] <JT-Shop> forming
[15:13:30] <_methods> thru spindle coolant
[15:13:42] <JT-Shop> no
[15:13:46] <_methods> will crank up price
[15:13:54] <_methods> http://www.mscdirect.com/product/details/79330585?src=pla&cid=PLA-Google-PLA+-+Test&CS_003=7867724&CS_010=79330585
[15:14:04] <_methods> $63
[15:34:31] <JT-Shop> http://www.mscdirect.com/product/details/70647532?rItem=70647532
[15:34:45] <JT-Shop> that's the one OSG said to use on my part
[15:35:32] <_methods> big money
[15:35:48] <_methods> you should get a lot of holes out of a thread former though
[15:36:17] <_methods> you doing a shallow blind tap?
[15:36:35] <JT-Shop> .5" deep blind hole
[15:36:50] <JT-Shop> I hope the drill bit shows up before I finish the job
[15:36:56] <_methods> lol
[15:37:10] <JT-Shop> 5.78mm drill bit
[15:37:24] <JT-Shop> only 1 in stock of the two choices they gave me
[15:38:07] <_methods> thread form taps aren't that picky about drill
[15:38:12] <_methods> 5.8 would work fine
[15:38:52] <_methods> 5.7/5.8
[15:39:25] <JT-Shop> too late now lol
[15:39:51] <_methods> hehe sorry
[15:40:10] <JT-Shop> so a #1 would work it is 5.79
[15:40:14] <_methods> yeah
[15:40:36] <_methods> definitely
[15:41:10] <_methods> it's not for food grade/medical part is it?
[15:41:13] <DaViruz> i doubt you can expect a drill bit to make a hole within 0.01mm regardless
[15:42:07] <DaViruz> if it was that important you'd have to ream it..
[15:42:08] <XXCoder> if it needs to be that precise then drill/reamer is best bet
[15:42:16] <_methods> thread form taps are pretty forgiving
[15:42:22] <_methods> i love em
[15:42:38] <DaViruz> i've never used one, not a real one at least
[15:42:40] <_methods> but unfortunately if you're doing medical/food you can't use them
[15:43:05] <_methods> you get great tap life out of them
[15:43:24] <JT-Shop> no it is a part for a compression relief tab grinder that I designed
[15:43:27] <DaViruz> _methods: how come?
[15:43:43] <DaViruz> creates surfaces for stuff to grow in?
[15:44:02] <_methods> it's because they form the thread instead off cutting them and the create cracks and crevices in the thread forms
[15:44:05] <_methods> for bacteria
[15:46:27] <_methods> http://extra.dormer.sandvik.com/PDF/formtaps/formtaps_en.pdf
[15:48:04] <_methods> on pg3 they have a cross section of threads
[15:48:52] <DaViruz> oh, i didn
[15:49:00] <DaViruz> 't realize they looked that rough
[15:49:15] <_methods> yeah
[15:52:24] <XXCoder> what method do hopsital equipment makers use?
[15:52:30] <_methods> normal taps
[15:52:30] <JT-Shop> wow the spec sheet says to tap at 1070 RPM... takes 1 second to tap the hole
[15:52:36] <XXCoder> ah
[15:53:20] <_methods> yeah thread formers tap fast
[15:53:42] <XXCoder> plenty jokes there
[15:53:44] <_methods> also takes more hp since you're forming the threads vs cutting them
[16:11:24] <Tom_itx> _methods, the spindle inertia would carry it thru as fast as it's going
[16:11:54] <bsilverman> Anyone know if the OpenStack Kilo VMAX driver supports FCoE?
[16:13:52] <Jymmmm> LOL, HE musta followed an old "EMC" link =)
[16:14:06] <Jymmmm> http://docs.openstack.org/kilo/config-reference/content/emc-vmax-driver.html
[16:14:51] <Jymmmm> Unless there's a new gcode over fiberchannel feature =)
[16:15:03] <Jymmmm> CloudCNC'ing
[16:15:14] <Jymmmm> VirtualCNC?
[16:15:21] <Jymmmm> CNC2GO
[16:24:32] <andypugh> Don’t talk to me about CloudCNC. That’s the real painful part of Fusion360. I have to save Inventor .ipt files to the “Cloud” then import them into a “Project”
[16:25:25] <JT-Shop> ouch
[16:26:50] <Jymmm> andypugh: WTH?! And if you happen to be "offline"?
[16:28:06] <Jymmm> andypugh: Is that a work thing (Ford), or personal?
[16:28:15] <andypugh> Tough, I guess. The f3d fle that is made from the .ipt is stored locally.
[16:28:44] <andypugh> Personal. But the Inventor license is a perk of the day job.
[16:29:09] <Jymmm> andypugh: There's no place like
[16:30:21] <Jymmm> andypugh: Dont have access to this do ya? https://www.youtube.com/watch?v=Wl5_wUVxRvw
[16:31:37] <MrSunshine> oh happy day ... ball nut was so gunked up it started to jam
[16:31:51] <MrSunshine> and noticed 1 ball was missing in the nut when i reassembled it :P
[16:32:17] <MrSunshine> how the heck to protect the nuts from dust ... bellows .. sure but i cant find any that are over 1m long
[16:32:20] * Jymmm hides the 2nd missing ball from MrSunshine
[16:32:21] * JT-Shop wonders what to do with all the pretty mirrors from the optical comparator
[16:32:44] <Jymmm> JT-Shop: are they on mounts? how many?
[16:33:18] <Jymmm> JT-Shop: what are you going to do with the XY table?
[16:33:33] <MrSunshine> btw, is there any special greace that should be used with ballnuts ?
[16:33:35] <andypugh> MrSunshine: http://www.hema-group.com/en/products/protection-systems/duraspring/
[16:34:01] <MrSunshine> andypugh: hmm, looks damn expensive =)
[16:34:08] <andypugh> Not too bad
[16:34:18] <MrSunshine> and i wonder how far they compress, i do not have to much space
[16:34:32] <andypugh> I just bought a pair of 650mm ones for 25mm screws and they were ÂŁ43 each
[16:35:00] <andypugh> MrSunshine: Download the PDF, that has all the dimensions.
[16:35:11] <MrSunshine> ah there
[16:35:22] <Jymmm> 3D Metal printer... https://www.youtube.com/watch?v=i6Px6RSL9Ac
[16:35:28] <andypugh> My 650mm ones compress to 50mm. But you can trade more diamter for shorter and vicky-vercky
[16:35:36] <JT-Shop> _methods, I can hold that forming tap in my ER collet ok?
[16:36:40] <andypugh> Jymmm: That metal forming thing is interesting, but I can’t help wondering if a CNC panel-beater might be quicker.
[16:37:25] <andypugh> Jymmm: Is that one of the versions of metal printiing where they need to infuse with braze?
[16:37:53] <Jymmm> andypugh: Not sure yet, still watching it.
[16:37:55] <MrSunshine> andypugh: looks like they get to fat :/
[16:37:59] <MrSunshine> 80mm outside diameter
[16:38:21] <MrSunshine> for one that is 1300 long
[16:38:51] <andypugh> You can use two back-to-back, but then it is longer when compressed
[16:38:57] <Jymmm> andypugh: infused with bronze powder then in the 2000F oven
[16:39:36] <MrSunshine> andypugh: yeah i guess thats true but that would be like 180ÂŁ per axis thaen :/
[16:39:56] <andypugh> Check Aliexpress, they are cheaper there
[16:41:23] <Praesmeodymium> they 3d print the dragonx rocket engine in inconel
[16:41:40] <Sync> better than your ballscrews being work MrSunshine
[16:44:19] <MrSunshine> hmm these nylong things in the ends of these chinese ballnuts, are they suposed to be some kind of a wiper ?
[16:45:00] <andypugh> Yes.
[16:45:46] <MrSunshine> there are two set screws to hold them in place, are they suposed to put some kind of preload on these wipers also ?
[16:45:51] <andypugh> They seem to work, too. The ballscrew on the Z of my lathe only has the nylon wipers and seems fine. (I didn’t design-in the space for spring covers or bellows when I converted)
[16:46:13] <MrSunshine> on the offending screw i noticed one set screw had backed of so the wiper was quite lose
[16:46:56] <andypugh> That won’t help, but I am not 100% sure that the screw is to push the wiper into the groove, though it can’t hurt.
[16:48:15] <_methods> JT-Shop: sure i'd put it in a tap collet though
[16:48:23] <_methods> but i've run them without tap collets before
[16:48:30] <JT-Shop> hmm I only have regular collets
[16:48:32] <_methods> if i only had 1 taps i'd use a tap collet for sure though
[16:48:40] <_methods> just to play it safe
[16:48:55] <JT-Shop> would you chamfer the hole first?
[16:48:59] <_methods> yes
[16:49:16] <_methods> i always spot tapped holes
[16:49:20] <JT-Shop> .250 diameter for a 1-4-20
[16:49:53] <_methods> sure i never really check unless the print calls out some specific chamfer
[16:49:55] <JT-Shop> does a tap collet have a square hole in the back?
[16:49:59] <_methods> yep
[16:50:21] <_methods> keeps your tap from spinning in tapping cycle
[16:50:27] <_methods> theoretically
[16:50:28] <_methods> lol
[16:50:58] <andypugh> Makes the tap more likely to break if it sticks :-)
[16:51:10] <_methods> if it spins its going to break
[16:51:21] <_methods> so pick your poison lol
[16:51:37] <andypugh> Not if it spins all the way out of the collet… Not sure that is better than breaking though
[16:51:53] <_methods> on the way out that would be the case
[16:52:06] <_methods> but on the way in spinning = crushed broken tap
[16:52:16] <JT-Shop> wow $100 for a tap collet
[16:52:27] <_methods> wow
[16:52:28] <_methods> no way
[16:52:32] <_methods> thats ridiculous
[16:52:43] <_methods> you should be able to buy a whole tap collet set for that much
[16:52:46] <JT-Shop> it's getting better
[16:54:25] <_methods> you just using er-32 collets?
[16:55:55] <JT-Shop> I have 11, 16, 20, 25, and 32
[16:56:41] <JT-Shop> not finding any sets...
[16:57:37] <_methods> yeah guess they're more expensive than i remember
[17:00:22] <_methods> do you have a tool sales guy you deal with?
[17:00:43] <_methods> he might be able to get you a better deal because i don't remember payin more than $200 for sets of tap collets
[17:01:31] <JT-Shop> a comment from Frank Mari of MariTool "Save your money. Tap collets are over rated, too expensive, and most often used in applications where it isn't needed. "
[17:01:49] <PetefromTn_> what material are you tapping?
[17:02:33] <JT-Shop> 7075 .5" deep blind hole .625" deep
[17:03:03] <JT-Shop> broke 2 spiral flute OSG electrolube taps when I started
[17:03:37] <PetefromTn_> are you peck tapping or going all in one pass?
[17:04:01] <JT-Shop> all the way
[17:05:20] <JT-Shop> I keep my 1/4-20 tap in an ER20 with a 17/64" collet so it is a close fit and it has no trouble snapping a spiral flute tap
[17:05:30] <PetefromTn_> I have used ER32's to form tap 1/4-20 without issue before. I assume you meant .5 deep in a .625 blind hole LOL
[17:05:42] <JT-Shop> aye
[17:06:42] <JT-Shop> did you jam it in a 1/4" collet or use a 9/32" collet?
[17:07:05] <_methods> like i said i've tapped plenty of holes without a tap collet but if you're having problems its best to eliminate variable
[17:07:13] <PetefromTn_> honestly don't remember but I recall using the tap in an ER32 collet
[17:07:17] <_methods> and tap spinning in a collet is definitely a variable
[17:07:50] <_methods> if i start breaking taps the first thing i do is make sure i'm using a tap collet
[17:09:38] <PetefromTn_> maybe I am just a hamfist with tightening ER32's LOL
[17:10:14] <_methods> hehe
[17:10:19] <_methods> gorilla pete
[17:10:40] <PetefromTn_> I hang every ounce of my 235 lbs off that wrench man hehehe
[17:11:15] <JT-Shop> I have plenty of cheater pipes lol
[17:11:16] <PetefromTn_> but my question is if you DO break a tap how did you determine it slipped?
[17:11:45] <PetefromTn_> and by then its too late ;)
[17:12:16] <JT-Shop> yea as soon as it slips it's usually over
[17:12:40] <JT-Shop> I've never broken a tap before using rigid tapping
[17:12:46] <_methods> well im usually watching very closely during setup and ill see them slip
[17:12:50] <JT-Shop> but I look at them under the scope first
[17:12:59] <PetefromTn_> ???? NEVER????
[17:13:27] <_methods> i mark my taps so i can see if they move in the collet
[17:13:28] <PetefromTn_> you've gotta be kidding me right?
[17:13:36] <JT-Shop> not till the other day when I broke two in a row
[17:13:40] <_methods> hahah
[17:13:42] <PetefromTn_> aah okay
[17:13:43] <JT-Shop> nope
[17:14:17] <JT-Shop> mark with a black marker?
[17:14:36] <_methods> gotta go eat
[17:14:36] <_methods> bbiab
[17:14:42] <JT-Shop> ok
[17:16:47] <JT-Shop> the last few times I made these parts it was 6061, I guess the 7075 is that much tougher that you can only use 65% thread depth on a spiral flute tap
[17:17:08] <JT-Shop> that's what finally worked for me but I was gun shy to go the full depth lol
[17:18:59] <PetefromTn_> you're my hero man
[17:19:19] <PetefromTn_> I have broken quite a few taps off in parts over the years maybe its me...LOL
[17:19:37] <Deejay> gn8
[17:19:40] <PetefromTn_> nope every other guy in the shops I worked in broke taps off in parts too LOL
[17:19:48] <JT-Shop> I only use OSG electralube taps and look at each one under the scope before use
[17:19:49] <PetefromTn_> GN8 DEEJAY!!
[17:20:01] <JT-Shop> if any wear is seen I don't use it
[17:20:08] <JT-Shop> goodnight
[17:20:50] <JT-Shop> when I found the electralube the torque needed to tap was much less (hand tapping back then so I could tell)
[17:26:57] <andypugh> JT-Shop: There are a fair few Rego-Fix tapping collets in eBay.
[17:27:29] <MrSunshine> anyone worked with vacuum pumps ? got a small one for making bent laminations and noticed the shop was all fogged out ... well ... has to be the oil mist from the damn pump .. :/
[17:27:41] <MrSunshine> what to do about that? place it outside and remote control it? =)
[17:27:48] <SpeedEvil> Oil agglomerator filter
[17:28:00] <JT-Shop> andypugh, thanks I'll have a look see
[17:28:03] <andypugh> Piston pump? Diffusion pump? Turbomolecular pump?
[17:28:08] <SpeedEvil> A compressor oil filter will work.
[17:28:17] <SpeedEvil> Somewhat at least
[17:28:26] <SpeedEvil> venting is not a bad idea
[17:29:31] <R2E4> Hi all....
[17:29:50] <R2E4> What are the options for Gantry router?
[17:29:51] <MrSunshine> https://carbix.nordicshops.com/PICTURE/485-4-vakuumpump_oil.jpg one of these ... dont know how it works internaly =)
[17:29:52] <JT-Shop> dang $30 with free shipping is much better
[17:31:26] <MrSunshine> SpeedEvil: hmm i wonder what that is named in swedish :/
[17:32:53] <andypugh> R2E4: Hardware options or software options?
[17:33:12] <MrSunshine> is one of those filters just a huge mass of something that cools down the mist and gets it alot of surface area to adhere to ? =)
[17:34:06] <R2E4> software, have a machine up and turning motors, 7i77, just trying to figure out bvest way for the double motors on Y
[17:34:23] <SpeedEvil> http://www.ebay.co.uk/itm/AFC-Air-Pressure-Regulator-oil-Water-Separator-Trap-Filter-Airbrush-Compressor-R-/131557280568?hash=item1ea16ccb38:g:AvgAAOSwu4BVpi5~ - this sort of thing
[17:34:25] <SpeedEvil> MrSunshine: Or DIY
[17:34:37] <andypugh> The best way is _probably_ gentrivkins and Joints-Axes
[17:34:51] <SpeedEvil> MrSunshine: make something that clamps a toilet roll (with the core removed) and vents through that.
[17:35:10] <andypugh> R2E4: Servos and homing to index on both sides?
[17:35:24] <MrSunshine> SpeedEvil: ah to get the paper to soak up the oil ? =)
[17:36:00] <SpeedEvil> MrSunshine: basically - it also slows it down and absorbs it
[17:36:08] <SpeedEvil> and catches any tiny droplets
[17:36:42] <MrSunshine> gonna try that tomorrow .. kinda urgent stuff to get laminated and dont want to ruine the whole shop :/
[17:37:40] <MrSunshine> i guess whole of those pneumatic oil separators could work also .. i even think ive got one of those laying around =)
[17:37:42] <R2E4> yes, need to home the Y
[17:38:06] <R2E4> I guess gantrykins is the way to go but is there a work around for the jogging in manual?
[17:38:28] <R2E4> Home both the Y motors
[17:40:32] <andypugh> R2E4: You can jog in World mode, both motors will move together.
[17:40:46] <zeeshan> anyone here hear of axyz routers?
[17:40:51] <zeeshan> axyz international
[17:41:34] <andypugh> R2E4: Gentrivkins works better, I believe, but you need to run the Joints-Axes experimental branch
[17:47:50] <Sync> MrSunshine: it is a rotary vane
[17:48:17] <R2E4> A beta for Joints-Axes?
[17:48:51] <Sync> zeeshan: they must be medium class, open screws and rails
[17:49:01] <zeeshan> sync i applied there
[17:49:04] <zeeshan> i got a phone interview on sat
[17:49:11] <Sync> ah
[17:49:16] <R2E4> hey Zee!!!!
[17:49:21] <zeeshan> hi
[17:49:31] <R2E4> Your plasma running LCNC
[17:49:43] <zeeshan> no plasma yet
[17:49:43] <zeeshan> :D
[17:49:56] <zeeshan> we built a table so far
[17:50:01] <zeeshan> still need to do thc
[17:50:18] <R2E4> OH, I thought you said you were using the THC from CandCNC on it last night
[17:50:22] <zeeshan> no
[17:50:27] <zeeshan> sounds like something jt would say
[17:50:33] <PetefromTn_> jeez man the guys at work were telling me about this restaurant called Deadbeat Pete's having some freaking fantastic burgers and now I can't get it outta my HEAD!!!
[17:50:43] <zeeshan> lol
[17:50:44] <zeeshan> get some!
[17:50:50] <PetefromTn_> R2E4 that was duv
[17:50:51] <PetefromTn_> duc
[17:51:08] <PetefromTn_> I might need to have some Hamburguesas
[17:51:44] <PetefromTn_> zeeshan good luck with the new job man
[17:51:56] <zeeshan> pete thanks man
[17:52:05] <zeeshan> im looking for some place wher ei can work for at least 5 y ears
[17:52:11] <Sync> already looking for another place? :D
[17:52:18] <zeeshan> Sync: my contract is up december
[17:52:34] <PetefromTn_> I never think that far ahead :(
[17:52:41] <Sync> ah
[17:53:04] <PetefromTn_> I ordered all my PC stuff last night
[17:53:09] <Sync> haha the toolchanger is quite
[17:53:11] <Sync> cute
[17:53:17] <PetefromTn_> except that damn picopsu thing
[17:53:18] <R2E4> AH
[17:53:29] <PetefromTn_> can't decide on which one I need
[17:53:50] <R2E4> ok, going to implement gantrykins for now and see how it goes.
[17:53:52] <PetefromTn_> I need to get the picopsu and the DIN mount 24v supplies ordered
[17:54:13] <Sync> get a puls one
[17:54:25] <PetefromTn_> puls?
[17:56:23] <Sync> it is a manufacturer of powersupplies
[17:56:36] <DaViruz> https://www.youtube.com/watch?v=kU63UiZEQZ8
[17:56:37] <DaViruz> seems pretty nice
[17:56:37] * zeeshan wonders if its so much to ask for a job that requires you to do calculation-based design and produce the design
[17:56:59] <zeeshan> that is nice
[17:57:01] <zeeshan> is that 24v
[17:58:54] <zeeshan> http://ca.indeed.com/cmp/Flamboro-Technical-Services/jobs/Mechanical-Designer-Detailer-34116ca2d7260e93?q=mechanical+engineer
[17:59:01] <zeeshan> i hope they get back tome!!!!!!1
[17:59:09] <zeeshan> i'd love to do this for a career
[17:59:27] <zeeshan> okay enough job whining
[17:59:48] <PetefromTn_> I will check out those puls models
[17:59:57] <PetefromTn_> Deadbeat Pete's it is!!
[18:00:01] <PetefromTn_> BBL
[18:00:20] <JT-Shop> goodnight
[18:05:07] <R2E4> What editor you guys using?
[18:05:31] <Tom_itx> gedit

[18:05:45] <Sync> vim
[18:05:55] <Tom_itx> copy con
[18:06:09] <Tom_itx> i bet few even get that

[18:06:35] <jthornton> copy console lol
[18:06:50] <R2E4> copy con, that was dos
[18:06:54] <zeeshan> nano
[18:06:55] <Tom_itx> i've done that quite a few times
[18:06:59] <R2E4> and I hate vi
[18:07:07] <R2E4> I use pico on terminal

[18:07:20] <jthornton> I still have a set of dos 6.something disks
[18:09:45] <Tom_itx> i still use 6.22
[18:10:01] <R2E4> pncconf wont do 2 Y axis
[18:10:01] <Tom_itx> last ver before windows
[18:10:06] <R2E4> ark....
[18:10:23] <Tom_itx> pico is ok
[18:10:29] <Tom_itx> gedit is easier
[18:10:43] <R2E4> mousepad
[18:12:54] <Tom_itx> i use programmer's notepad in windows
[18:13:35] <Tom_itx> wordstar
[18:14:37] <ssi> wordstar hiphop?
[18:14:59] <jthornton> what was the word processor that opened up to a blank prompt?
[18:15:18] <Tom_itx> iirc qedit did
[18:15:43] <Tom_itx> https://en.wikipedia.org/wiki/WordStar
[18:15:47] <Tom_itx> for you young pups
[18:16:19] <ssi> cool it grandpa
[18:16:58] <Tom_itx> not quite
[18:17:44] <jthornton> I think it was wordperfect for dos
[18:17:59] <Tom_itx> lotus was another tricky one to use
[18:18:10] <Jymmm> Tom_itx: Biotch, I got WordStar, original box/binder with VERTICAL FUNCTION KEYS overlays =)
[18:18:14] <Tom_itx> spreadsheet
[18:18:25] <Tom_itx> you're an ole fu** ehh?
[18:18:39] <Tom_itx> i had overlays too
[18:18:48] <Jymmm> VERTICAL?
[18:18:57] <Tom_itx> you actually got documentation with software back then
[18:19:23] <Tom_itx> i don't remember... on app i had was vertical
[18:19:48] <Tom_itx> that kbd still works too btw
[18:20:00] <Tom_itx> just don't drop it on your foot
[18:20:16] <ssi> why are we talking about antique word processors?
[18:20:17] <Jymmm> Tom_itx: http://oi44.tinypic.com/161dbf4.jpg
[18:20:29] <Tom_itx> ssi, to make you feel left out?
[18:20:46] <CaptHindsight> does that tooth at 195 deg look chipped or is it an illusion? http://ibin.co/2LYjutZrGWJh
[18:20:47] <Jymmm> Tom_itx: http://oi40.tinypic.com/34ngkr6.jpg
[18:21:06] <jthornton> been doing so much golang I forgot the python for syntax lol
[18:21:07] <ssi> I don't feel left out
[18:21:13] <ssi> I'm a vi power user
[18:21:19] <ssi> I don't use newfangled crap like wordstar
[18:21:45] <ssi> jthornton: I'm glad you like golang... I think it's great
[18:21:50] <Tom_itx> CaptHindsight, it kinda does
[18:21:51] <fenn> the tooth is chipped
[18:21:55] <Jymmm> Tom_itx: Talk about old fuck --> ssi
[18:21:57] <andypugh> CaptHindsight: Might just be that that one isn’t covered in grease. It isn’t a part of the tooth that touches the worm.
[18:22:02] <Sync> besides their coc ssi
[18:22:16] <Tom_itx> yeah the tip is, may not affect it much
[18:22:34] <Tom_itx> ahh i bet andy's right
[18:23:33] <zeeshan> https://youtu.be/_Dbn5IuoxkI
[18:23:37] <zeeshan> i see haas back there
[18:23:37] <zeeshan> !
[18:23:42] <zeeshan> https://youtu.be/_Dbn5IuoxkI?t=129
[18:23:44] <zeeshan> whoops
[18:24:06] <zeeshan> 30 sec before that
[18:24:07] <jthornton> yea once I got over the inital hump it is pretty easy
[18:24:17] <jthornton> initial
[18:24:26] <ssi> yeah it's very easy
[18:24:30] <ssi> it's quick to write powerful stuff
[18:24:36] <Tom_itx> CaptHindsight, wipe off the grease and take another pic for us :)
[18:24:51] <ssi> I'm back in the realm of embedded C, which is the opposite of that :)
[18:25:04] <ssi> I've been sweating over multiple indirection pointers and bit packing all day
[18:25:05] <Tom_itx> for what chips?
[18:25:13] <ssi> stm32f4
[18:25:17] <Tom_itx> arm
[18:25:19] <ssi> yes
[18:25:24] <zeeshan> youre an arm
[18:25:27] <CaptHindsight> ^^ one of those used super precision rotary tables for 1/12th the cost of new
[18:25:39] <ssi> zeeshan: thank you?
[18:25:41] <Tom_itx> better grab it
[18:27:04] <CaptHindsight> https://www.youtube.com/watch?v=pfzCyTwUtXA video of it running
[18:27:14] <zeeshan> gimme!!!!!!1
[18:28:03] <Sync> zeeshan: hm, not super impressed with the machines
[18:28:13] <zeeshan> i just saw a video of it eating aluminum
[18:28:22] <zeeshan> another machine had a er32 collet system on it
[18:28:23] <zeeshan> lol
[18:34:10] <Sync> with the supported rails and everything open
[18:36:09] <ssi> Sync: so rene wrecked my world with the input/output thing earlier
[18:36:16] <Sync> 0o
[18:36:19] <ssi> now I have to re-read all the smartserial docs and try to figure out where it all went wrong :(
[18:38:03] <Sync> ):
[18:38:19] <ssi> it's really confusing keeping tx/rx and input/output straight when working on the remote end
[18:38:38] <ssi> and I thought I had it all sorted out, everything is by convention named from the host end
[18:38:44] <zeeshan> what are you doing
[18:38:45] <ssi> so inputs are inputs FROM the remote TO the host
[18:38:49] <ssi> but apparently that's not right
[18:38:58] <ssi> furthermore, it seems like it might be inconsistent in the docs
[18:39:03] <ssi> zeeshan: same thing I've been doing
[18:39:19] <zeeshan> cnc mill?:
[18:39:20] <zeeshan> d
[18:39:24] <ssi> yes
[18:39:53] <ssi> hm no, the manual definitely agrees with what I expected
[18:40:01] <ssi> The DATA_DIRECTION field is a single byte field that specifies the data direction. Valid Data direction bytes are as follows:
[18:40:18] <ssi> 0x00 INPUT (Read from remote)
[18:40:26] <ssi> 0x80 OUTPUT (Written to remote)
[18:41:01] <ssi> but he's basing that on the fact that show hal configuration shows IN/OUT backwards from what we expected
[18:41:29] <ssi> and now that I'm looking at it, that's correct
[18:41:46] <ssi> cmd_vel shows up as IN, because you would wire a source to it
[18:41:51] <ssi> it's a hal pin that receives a value
[18:42:08] <ssi> but from the perpective of the sserial driver, it's an output to the remote
[18:42:45] <R2E4> Anyone doing Gantrykins here?
[18:43:12] <ssi> R2E4: I am
[18:43:55] <ssi> Sync: I feel SO MUCH BETTER now :D
[18:45:48] <R2E4> Do I need two Axis Y section in HAL?
[18:45:59] <ssi> R2E4: are you running joints_axes branch?
[18:46:23] <R2E4> I set it up to what I think it should be and joint 2 is acting like joint 1 is suppoe to be.
[18:46:30] <R2E4> no
[18:46:44] <ssi> I have only done gantrykins successfully with ja
[18:47:23] <Tom_itx> ssi, easy mistake to make on the IO
[18:47:46] <ssi> yeah
[18:47:50] <ssi> he was certain I had it all wrong
[18:47:53] <Tom_itx> i had to doublecheck the wiring the first time
[18:47:56] <ssi> I was gonna pull my hair out if that was the case
[18:48:07] <ssi> because the input and output bytes in discoveryrpc are definitely named wrt the host
[18:48:22] <ssi> it would be sheer madness if the input/output flags in the descriptors were backwards wrt that convention
[18:48:23] <Tom_itx> i got a 7i84 i need to check one of these days
[18:48:43] <Sync> ah, confusing for sure ssi
[18:48:50] <Sync> zeeshan: halp!
[18:49:09] <R2E4> ssi: did you try gantrykins with stable branch?
[18:49:22] <ssi> no
[18:49:49] <R2E4> I cant load a beta version on customer system.
[18:50:01] <ssi> ja isn't exactly beta
[18:50:20] <ssi> I wasn't satisfied with the options for doing a gantry machine without ja
[18:50:25] <Tom_itx> you implementing it on an arm?
[18:50:27] <ssi> there's ways to do it, but none of them pleased me
[18:50:28] <Tom_itx> sserial
[18:50:31] <R2E4> are you running gantrykins or gentrivkins?
[18:50:35] <ssi> Tom_itx: yes
[18:50:38] <ssi> R2E4: ah sorry gentrivkins
[18:50:49] <Tom_itx> would make a nice frontend for a number of things
[18:51:09] <R2E4> Does Gantrykins work?
[18:51:11] <ssi> Tom_itx: yeah once I have it fully understood it could be ported to other projects
[18:51:19] <Tom_itx> exactly
[18:51:24] <ssi> R2E4: it didn't work properly when I set those machines up
[18:51:48] <Tom_itx> i've got a 32F4 board here if you want one
[18:51:56] <Tom_itx> stm32F4
[18:52:04] <Tom_itx> i'll never find time to use it
[18:52:32] <ssi> I dunno that I really need it, I have an stm32f1 discovery board here, and I have all the boards that we built
[18:53:35] <R2E4> I really dont wont to put mach3 on his system....
[18:53:39] <R2E4> lol
[18:54:44] <CaptHindsight> ssi: whatcha workinon with the stm32f?
[18:55:02] <Tom_itx> sserial remote it sounds like
[18:55:15] <ssi> CaptHindsight: servo drive
[19:17:34] <R2E4> Gantrykins require 2 Y sections in HAL?
[19:26:09] <R2E4> cant have two Y sections....lol
[19:26:42] <ssi> well crap, I seem to have crashed the arm, and I can't reconnect with term anymore :(
[19:27:17] <Tom_itx> woops
[19:28:20] <ssi> yeah that's not good :(
[19:28:31] <Tom_itx> R2E4, http://linuxcnc.org/docs/html/man/man9/gantrykins.9.html
[19:28:33] <Tom_itx> The coordinates= parameter specifies the initial gantry joint mapping. Each axis letter is mapped to a joint, starting from 0. So coordinates=XYYZ maps the X axis to joint 0, the Y axis to joint 1 and 2, and the Z axis to joint 3.
[19:31:26] <Sync> I had that happen a few times ssi
[19:31:31] <Sync> try replugging it
[19:31:34] <ssi> I have
[19:31:37] <ssi> I can't make it come back for anything
[19:31:42] <ssi> I've reverted back to rene's HEAD
[19:31:44] <ssi> which I know works
[19:31:56] <ssi> can't get term to connect, not for anything
[19:32:03] <Sync> is the device there?
[19:32:15] <Sync> I sometimes have sticky devices for some reason
[19:32:27] <ssi> doesn't look like it
[19:32:47] <ssi> oddly, it looks like the device is responding over smartserial
[19:33:05] <Sync> for me the usb stuff was flaky as well
[19:33:27] <Sync> the nextgen™®© hardware will have the option of rs422/485 for the term
[19:33:31] <R2E4> Tom, I read that,
[19:33:56] <ssi> this is frustrating... I kinda need the term
[19:34:16] <Sync> I feel you
[19:34:39] <Sync> hm, can you still flash it through the dfu?
[19:34:46] <ssi> yes I can flash it
[19:34:51] <ssi> I've been using the stlink for all my flashing
[19:34:51] <Sync> hmm
[19:34:54] <R2E4> Why does it only show 3 joints in axis when I clearly have 4 programmed.
[19:34:58] <Sync> ah
[19:35:04] <ssi> and it seems to be running happily despite having no term
[19:35:07] <Sync> because you can use the dfu to flash it over usb
[19:35:12] <ssi> oh I haven't tried that
[19:35:39] <Tom_itx> does it have a bootloader?
[19:35:43] <Sync> of course
[19:35:49] <Tom_itx> yeah dfu should work then
[19:35:56] <Tom_itx> i'm not familiar with arm
[19:36:25] <Sync> most if not all of them come with a serial bootloader, the ones featuring usb usually have dfu too
[19:36:30] <zeeshan> dfu?
[19:36:36] <Sync> device firmware update
[19:36:39] <zeeshan> ah
[19:36:44] <Sync> or something like that
[19:36:47] <ssi> it's teh "device is fucked up" mode
[19:37:19] <zeeshan> i dunno where ive seen that term before
[19:37:37] <ssi> ever use a smartphone? :P
[19:38:05] <zeeshan> yes
[19:38:11] <zeeshan> i think it was when jail breaking iphone
[19:38:14] <ssi> there you go
[19:38:18] <ssi> http://www.target.com/p/nuka-cola-quantum-for-fallout-4/-/A-50148691#prodSlot=medium_1_10&term=fallout
[19:38:29] <ssi> http://i.imgur.com/1F8gw3T.jpg
[19:38:36] <zeeshan> the other night i was thinking
[19:38:39] <zeeshan> why do people call it torque control
[19:38:41] <zeeshan> and speed control
[19:38:51] <zeeshan> could you not also call it current control and voltage control? :D
[19:38:58] <ssi> current control, yes
[19:39:06] <ssi> and torque/current are used somewhat interchangeably
[19:39:07] <Sync> voltage, not so much
[19:39:12] <ssi> I don't tihnk voltage control is accurate
[19:39:14] <zeeshan> but isn't that speed control?
[19:39:17] <ssi> no
[19:39:20] <zeeshan> you vary the pulse of voltage
[19:39:22] <zeeshan> and amplitude
[19:39:32] <zeeshan> duration and amplitude i mean
[19:39:45] <Sync> just because you apply a voltage does not mean the motor spins at n rpm
[19:39:56] <ssi> yeah, the kv constant is specified unloaded
[19:40:09] <Sync> it just gives you the maximum no load rpm
[19:40:17] <ssi> and since the motor is a relatively constant impedance, the current is going to vary in proportion to the voltage
[19:40:28] <ssi> so there's not really any such thing as current control vs voltage control, they're two sides of the same coin
[19:40:57] <Sync> well, that also depends
[19:41:03] <ssi> it does
[19:41:06] <Sync> on how your control algo works
[19:41:10] <Sync> some output a voltage
[19:41:11] <ssi> but for the purposes of zee's point it's accurate enough :)
[19:41:17] <Sync> and some actually control the current
[19:41:26] <zeeshan> no i mean like
[19:41:33] <zeeshan> in one you're controlling current and voltage can be whatever
[19:41:38] <Sync> negative
[19:41:47] <ssi> zeeshan: go apply a voltage to a resistor
[19:41:49] <Sync> the voltage will be the same
[19:41:53] <ssi> then go apply a current to the same resistor
[19:42:00] <ssi> and tell me that you can control them independently
[19:42:04] <zeeshan> youre thinking of it steady state
[19:42:13] <zeeshan> if you give pulses of current
[19:42:22] <Sync> which average to a given current
[19:42:26] <zeeshan> you can control thje torque
[19:42:35] <Sync> your cutoff frequency is way lower than your pwm frequency
[19:42:43] <ssi> at the lowest level, all you're ever doing is controlling the current
[19:42:47] <Sync> so you can look at it as if it was steady state
[19:42:54] <ssi> which loop you close depends on the type of feedback you have and what you use as your process variable
[19:43:50] <zeeshan> http://www-personal.umich.edu/~ykoren/uploads/Torque_and_speed_control_of_DC-servomotors_for_Robots.pdf
[19:43:53] <zeeshan> maybe i intrepreted this paper wrong
[19:44:29] <jdh> http://tinyurl.com/og9yofx
[19:44:54] <Sync> for equal loads, the currents/voltages are equal zeeshan
[19:45:00] <zeeshan> i know that
[19:45:02] <zeeshan> silly :P
[19:45:03] <zeeshan> read the paper
[19:45:10] <zeeshan> its not long!
[19:45:33] <Sync> I don't need to
[19:45:36] <zeeshan> Torque control, based on manipulation of DC motor current, utilizes usually a current + am lifier in the motor's drive unit. A current amplima device w ich supplies a current proportional to its input voltage, and has a high output resistance.
[19:45:47] <zeeshan> cause what you guys are saying doesnt agree w/ what this dude is sayin
[19:46:10] <zeeshan> The alternative approach is to control the speed of the robot arm by manipulation of the DC motor voltage, utilizing a voltage am lifier in the motor's drive unit. Similar approach is +. usua y used in hydraulic driven robots. A voltage amplifier provides an output voltage proportional to its input voltage, and is capable to supply the current required by the motor.
[19:46:17] <zeeshan> there i pasted relevant text
[19:46:22] <zeeshan> mr i don't need to read
[19:47:34] <Sync> that is what we already said
[19:47:38] <zeeshan> no
[19:47:46] <zeeshan> you said i wasn't correct
[19:47:59] <Sync> you are misinterpreting it
[19:48:05] <zeeshan> by saying torque control is like controlling current
[19:48:19] <Sync> that is still true
[19:48:30] <zeeshan> what was the point you were making
[19:48:32] <zeeshan> cause i didnt get it
[19:48:35] <zeeshan> =/
[19:48:58] <Sync> controlling velocity is not voltage control
[19:49:34] <Sync> the point he makes is, you can use a voltage amplifier to control velocity
[19:50:02] <ssi> which is what a velocity mode servo amplifier is
[19:50:11] <ssi> you need velocity feedback to do it
[19:50:33] <ssi> whereas a current mode drive can get its feedback directly from the motor power lines
[19:50:40] <ssi> via current sensing and back emf
[19:50:46] <zeeshan> oh no that is not what i meant
[19:50:57] <zeeshan> both these control need feedback from a real encoder
[19:51:04] <Sync> no
[19:51:07] <ssi> current mode doesn't
[19:51:12] <ssi> and velocity mode only needs a tacho
[19:51:15] <ssi> or encoder or any other vel fb
[19:51:20] <Sync> a torque controller only needs a current value
[19:51:51] <ssi> the difference is that torque is proportional to current, whereas velocity is not proportional to voltage
[19:52:14] <zeeshan> what is it proportional to
[19:52:17] <zeeshan> (voltage)
[19:52:22] <zeeshan> i always thought it was voltage!
[19:52:25] <zeeshan> times some constant
[19:52:32] <ssi> yes, the kv constant
[19:52:34] <ssi> that's true unloaded
[19:52:36] <ssi> it's not true dynamically
[19:53:31] <ssi> I guess I'mma rebooit this machine and hope usb will come back up on term
[20:00:59] <zeeshan> going from theoretical control
[20:01:05] <zeeshan> to practical control is a big transition :p
[20:02:22] <Sync> it is pretty pracical
[20:05:28] <ssi> Sync: reboot brought it back
[20:06:21] <ssi> I crashed the thread straightaway though :D
[20:08:34] <Sync> nice
[20:08:48] <Sync> but yeah I had that happen a few times too
[20:09:05] <Sync> but the other guys never had it running apples
[20:09:29] <PetefromTn_> well deadbeat pete's was not all it was cracked up to be LOL
[20:09:42] <ssi> apples?
[20:10:10] <PetefromTn_> Burgers
[20:12:57] <Sync> ssi: apple devices
[20:13:39] <ssi> oh I get you now
[20:13:45] <PetefromTn_> heh
[20:13:46] <ssi> I'm on osx, this is the first usb glitch I've had
[20:14:44] <R2E4> ssi:n is getting ja a difficult task?
[20:14:59] <ssi> not particularly, just have to build from source
[20:15:06] <R2E4> hahaha
[20:17:27] <ssi> ugh I hate when I get these things that just interrupt my whole workflow
[20:17:30] <ssi> and I can't find the rhythm again
[20:17:57] <jdh> I had a 1.5 day project starting Tuesday. Hoping to finish it tomorrow
[20:18:36] <ssi> three half days is 1.5 days :)
[20:18:46] <Sync> I know that feeling
[20:18:53] <jdh> had to fix/redo/etc tons of unrelated things to get my changes tested
[20:20:00] <jdh> should save <$200k/year in helium and tons of hours of downtime
[20:22:43] <_methods> oh so you were involved in that blimp that got away lol
[20:27:12] <ssi> oh weird, it bitpacks differently than I expected
[20:27:44] <ssi> for a four bit pd followed by a 12 bit pd
[20:27:55] <ssi> where pd1 is set to 0xf and pd2 is set to 0xabc
[20:28:06] <ssi> it looks like the packed bytes are 0xcf 0xab
[20:37:12] <PetefromTn_> GAAH why can't I find a picopsu power supply what is variable DC input and 24pin anywhere LOL
[20:37:22] <zeeshan> i thought we saw it on that website
[20:37:23] <ssi> not sure they make one
[20:37:46] <PetefromTn_> I wonder if that is true why not?
[20:38:09] <zeeshan> http://www.mini-box.com/PicoPSU-120-WI-25-12-25V-DC-DC-ATX-power-supply
[20:38:11] <zeeshan> isnt this it?
[20:38:26] <ssi> that's 20 pin
[20:38:32] <SpeedEvil> I've contemplated DIY for the lulz.
[20:38:35] <SpeedEvil> It's not _that_ hard.
[20:38:39] <ssi> no, it's not
[20:38:50] <SpeedEvil> (to make a 20-36V in)
[20:38:56] <PetefromTn_> yeah thats 20 pin
[20:39:01] <SpeedEvil> >95%
[20:44:35] <ssi> SpeedEvil: get on it
[20:44:48] <ssi> start a design, I'll have some boards made and build a few
[20:50:34] <Tom_itx> http://www.mini-box.com/PicoPSU-80-WI-32V
[20:50:35] <Tom_itx> 32v
[20:51:10] <PetefromTn_> 20 pin
[20:51:20] <Tom_itx> you need what?
[20:51:31] <PetefromTn_> 24 I guess
[20:51:34] <Tom_itx> i didn't bother to count the pins on mine
[20:51:40] <Tom_itx> i think 20 will work though
[20:51:55] <Tom_itx> don't quote me on that
[20:52:17] <Tom_itx> i'd call em
[20:52:55] <PetefromTn_> what do you want me to call em? ;)
[20:53:58] <Tom_itx> i guess it's my itx one that is 20, the atx is 24
[20:54:10] <Tom_itx> so sue me
[20:54:12] <Tom_itx> :)
[20:54:26] <PetefromTn_> ok lol
[20:54:57] <Tom_itx> i had an older one i couldn't use too because it doesn't have sata plugs
[20:55:03] <Tom_itx> well i could have but..
[20:57:57] <PetefromTn_> http://www.ebay.com/itm/200W-high-power-24pin-mini-ITX-DC-ATX-power-supply-w-16V-24VDC-wide-range-input-/400569517436 !!??
[20:58:35] <Tom_itx> give it a try
[20:58:40] <Tom_itx> keep in mind it's china
[20:58:45] <Tom_itx> it's probably fine
[20:58:56] <PetefromTn_> it says pico box?
[20:59:12] <Tom_itx> so do arduino clones say arduino
[20:59:33] <PetefromTn_> shit it says it wont get here until thanksgiving damnit
[20:59:48] <Tom_itx> it's worth at shot
[21:00:06] <Tom_itx> even if it fails... have you ever wasted $26 before??
[21:01:05] <PetefromTn_> NEVA!!!
[21:01:58] <PetefromTn_> yeah but I don't feel like wiating for it
[21:05:44] <ssi> hm
[21:12:21] <PetefromTn_> well the only thing that comes to mind is to get one of those DC regulator cards andy posted yesterday and using a 12v 24 pin module instead of a 24v one which I can only get on the slow boat
[21:18:45] <ssi> or just get a cheap 12v switcher
[21:19:58] <PetefromTn_> if I gotta get a seperate power supply it kind of defeats the purpose of using the dc input over the typical 120v PC supply I was going to use I think
[21:20:24] <ssi> same if you have to get a separate regulator
[21:20:29] <ssi> just get a pc supply then
[21:27:43] <PetefromTn_> http://www.amazon.com/FrozenCPU-20-pin-24-pin-Supply-Adapter/dp/B0030CQ9FA I guess this would work too
[21:29:32] <R2E4> ssi: can I run the JA branch on top of the 2.6? or do I need 2.7?
[21:32:59] <PetefromTn_> http://www.ebay.com/itm/DC-DC-Step-down-Buck-Converter-Adjustable-Power-4V-38V-to-1-25V-36V-5A-Voltmeter-/171445007919?hash=item27eaeb362f:g:qBwAAOxyNThTcwQm
[21:33:03] <PetefromTn_> those are 5amp
[21:33:42] <PetefromTn_> comments on my PC board seem to think that it runs about 40 or so watts max so that should work actually
[21:37:30] <ssi> R2E4: you can use 2.6
[21:40:11] <R2E4> IS there a specific location somewhere in some closet that the docs are located?
[21:40:27] <ssi> yeah somewhere
[21:40:45] <R2E4> lol
[21:40:46] <ssi> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?JointAxesBranch
[21:41:17] <ssi> I'm not sure if there's a page specifically for building ja
[21:41:28] <ssi> but basically the procedure is the same as building master, you just need to switch branches in git first
[21:45:22] <Tom_itx> PetefromTn_, those are probably not a full 5A
[21:45:42] <Tom_itx> it depends on the choke used
[21:46:20] <Tom_itx> i got a bunch of similar ones, some with and some without the leds
[21:46:58] <R2E4> yeah, I'm not using git. I installed from live CD
[21:48:34] <ssi> I guess you have a bit of reading to do then :)
[21:48:50] <Tom_itx> PetefromTn_, this is probably the chip being used: http://tom-itx.no-ip.biz:81/~webpage/pdf/LM2596_switcher.pdf
[21:49:02] <ssi> sorry I'm not more help, but it's been a few years since I did it, and I'd have to dive back in and read up to do it again
[21:49:15] <Tom_itx> i made a 3A 5v fixed version of it myself
[21:49:17] <ssi> and right now I'm elbows deep in sserial code so I don't really have time to go learn it so I can teach it
[21:49:43] <R2E4> no problem, I'm not asking you to teach it to me.
[21:49:53] <Tom_itx> git branch
[21:49:58] <Tom_itx> git checkout xxx
[21:52:20] <Tom_itx> PetefromTn_, somewhere in that pdf it shows performance curves for various chokes
[21:53:21] <Tom_itx> choke/cap combinations
[21:53:46] <PetefromTn_> Tom_itx so I suppose its not a great idea then
[21:54:08] <Tom_itx> P16 shows some for fixed voltage designs
[21:54:20] <Tom_itx> i got a couple different chokes when i was doing mine
[21:54:23] <PetefromTn_> what would you do go with the 24v 20 pin and use that harness to make it fit or something else
[21:54:39] <Tom_itx> i'd ask em if you can do that
[21:55:00] <Tom_itx> if they say yes, i'd get the pico psu one at 36v probably
[21:55:13] <PetefromTn_> I was looking again at the meanwell power supplies that 350 amp one would be nice even tho its not Din rail mount
[21:55:14] <Tom_itx> or put a wart on it like i did and run 12v
[21:55:48] <Tom_itx> the 8A wart has a fan in it
[21:55:54] <Tom_itx> i don't think mine ever came on
[21:56:02] <Tom_itx> the 5A one doesn't
[21:56:21] <PetefromTn_> yeah I don't really want to do that If I am going to use DC to power the PC I want it to be something like that picopsu setup
[21:56:54] <Tom_itx> then tap into your supply to get a suitable v source
[21:57:19] <Tom_itx> are you running a switcher supply?
[21:57:22] <Tom_itx> or linear?
[21:57:32] <PetefromTn_> I have not bought the supply yet
[21:57:55] <Tom_itx> i used linear on mine because the stuff was surplus, available and cheap
[21:58:29] <PetefromTn_> honestly the meanwells look nice and I could get a 24v and a 12v for under a hundred probably and then use one of those boards to step down to 5v for the mesa card
[21:58:54] <Tom_itx> i will tell you the chinese ones don't have thermal or over v shutdown
[21:59:02] <Tom_itx> don't ask how i know :D
[21:59:20] <PetefromTn_> I thought they did? the meanwells are chinese no?
[21:59:32] <Tom_itx> they're supposed to
[21:59:43] <Tom_itx> i'm talking about that buck think you posted
[21:59:50] <Tom_itx> thing*
[22:00:00] <PetefromTn_> yeah it would only be for 5v logic in this instance
[22:00:01] <Tom_itx> http://www.ebay.com/itm/DC-DC-Step-down-Buck-Converter-Adjustable-Power-4V-38V-to-1-25V-36V-5A-Voltmeter-/171445007919?hash=item27eaeb362f:g:qBwAAOxyNThTcwQm
[22:00:13] <Tom_itx> should work fine for the 5v stuff
[22:00:18] <Tom_itx> that's what i'm using
[22:00:21] <PetefromTn_> I would hope so
[22:00:45] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/5v_switcher.jpg
[22:00:47] <Tom_itx> same chip
[22:00:52] <PetefromTn_> the question is then if I get TWO DC supplies one 12 and one 24 they both do not need to be too big really
[22:00:53] <Tom_itx> fixed 5v out
[22:01:19] <Tom_itx> i tapped off my 24v to get my 10v needed for my spindle dac
[22:01:45] <Tom_itx> my xfrmrs had a centertap
[22:02:46] <Tom_itx> i just used a quarterwave to a cap to get it
[22:03:13] <PetefromTn_> http://www.ebay.com/itm/MW-12V-12-45A-AC-DC-PSU-Switching-Power-Supply-Mean-Well-NES-150-12-150W-UL-/231726867484?hash=item35f3ff641c:g:tFMAAOSwZjJVAKBX

[22:03:31] <PetefromTn_> those two
[22:03:49] <PetefromTn_> and that board for 5v and a 12v 24pin picopsu
[22:03:58] <Tom_itx> this is to control what?
[22:04:06] <Tom_itx> err supply rather
[22:04:06] <PetefromTn_> basically everything
[22:04:17] <PetefromTn_> PC and 24v field
[22:04:31] <PetefromTn_> possibly the monitor too if I can figure out how
[22:04:38] <Tom_itx> you don't need alot for either one of those
[22:04:49] <Tom_itx> unless you have alot of power hungry relays
[22:04:52] <PetefromTn_> Oh and my contactor/relays
[22:06:23] <PetefromTn_> that's only like $125 for all three items pretty cheap really and should be MORE than enough to run that stuff and anything else I ever decide to plug in most likely
[22:07:11] <Tom_itx> so all you need is 12 & 24v?
[22:07:12] <PetefromTn_> the other option is smaller of the same ones in Din rail mounts but they are a bit more money for less watts
[22:07:17] <Tom_itx> and a buck for the 5v
[22:07:24] <PetefromTn_> 12,24,5
[22:07:26] <Tom_itx> besides your drives
[22:07:37] <PetefromTn_> drives are all AC
[22:07:43] <Tom_itx> what's on 12v?
[22:08:03] <PetefromTn_> well the PC would be because they do not make that damn connector in 24v 24 pin
[22:08:33] <Tom_itx> why get that big arse supply when a wart would work for that?
[22:08:42] <Tom_itx> then all you need is the 24v one
[22:08:48] <Tom_itx> and wire the buck to that for the 5v
[22:08:59] <PetefromTn_> I don't like putting warts inside a commercial machine
[22:09:49] <PetefromTn_> I am sure they would probably work fine
[22:10:09] <Tom_itx> too bad you can't find one that has 24 & 12 out together
[22:10:16] <Tom_itx> i'm sure they make em
[22:10:45] <PetefromTn_> simplest would be JUST that big 24v supply and the picopsu in 24v 20 pin to that connector cable
[22:11:10] <Tom_itx> if you can get by with 20 pins

[22:19:13] <Tom_itx> only 600ma 12v
[22:19:50] <PetefromTn_> http://www.automationdirect.com/adc/Shopping/Catalog/Power_Products_(Electrical)/DC_Power_Supplies/24VDC,_DIN_Rail_Mount/PSB24-120
[22:20:29] <PetefromTn_> both of those are just over a hundred bucks
[22:20:42] <PetefromTn_> plus the 12v picopsu 12v is like another 40
[22:20:53] <PetefromTn_> plus the little board for the 5v
[22:21:05] <PetefromTn_> around $150.00 total
[22:21:11] <Tom_itx> those are dirt cheap
[22:21:13] <PetefromTn_> and nice din rail mount
[22:21:24] <Tom_itx> you can get them for like $3 with the display iirc
[22:21:27] <Tom_itx> maybe 5 or so
[22:21:56] <Tom_itx> i got ~ half dozen last time i got some
[22:21:57] <PetefromTn_> how much power does the typical lcd pc flatscreen use?
[22:22:14] <Tom_itx> no idea
[22:22:22] <Tom_itx> the backlight would take the mose
[22:22:24] <Tom_itx> most
[22:23:03] <Tom_itx> and the older most likely the more power
[22:23:41] <Tom_itx> i'd wire that right into your supply input thoug
[22:23:43] <Tom_itx> h
[22:23:44] <PetefromTn_> http://www.newegg.com/Product/Product.aspx?Item=N82E16824160064
[22:23:49] <PetefromTn_> that one says 8 watts max
[22:23:59] <Tom_itx> that shouldn't be an issue
[22:24:09] <PetefromTn_> what do you mean?
[22:24:15] <PetefromTn_> AC?
[22:24:18] <Tom_itx> it's got it's own supply cord
[22:24:29] <Tom_itx> just wire it into the input
[22:24:36] <PetefromTn_> zeeshan said he used dc to power his monitor
[22:24:47] <PetefromTn_> that would be nice
[22:25:01] <Tom_itx> shouldn't really make any difference
[22:25:02] <PetefromTn_> everthing PC runs of the DC power supply
[22:25:27] <PetefromTn_> hang on let me look at my monitor I have here...
[22:27:03] <Tom_itx> and if it's run off AC you don't have to worry about replacement if it gets broken
[22:27:18] <Tom_itx> where with DC you'd have to find a similar one with similar current ratings
[22:27:33] <PetefromTn_> yeah the one I was planning to use is AC direct input
[22:27:48] <PetefromTn_> the one in the Cincinatti is a wall wart 12v 1.5amp
[22:27:50] <Tom_itx> then power isn't an issue on the monitor
[22:28:01] <PetefromTn_> no I suppose not
[22:28:04] <Tom_itx> ahem...
[22:28:13] <Tom_itx> no warts ? :D
[22:28:42] <PetefromTn_> hey this was done before I found out you could do this with DC power supplies ;)
[22:28:52] <Tom_itx> yeah
[22:29:09] <PetefromTn_> I ran a 120v cable up from the back of the machine to the front pendant
[22:29:11] <Tom_itx> i used what i had available to me
[22:29:18] <PetefromTn_> which is what I am trying to avoid here
[22:29:29] <Tom_itx> if cost wasn't an object i'd have done things differently
[22:29:32] <PetefromTn_> yeah I understand that man..
[22:29:42] <Tom_itx> it's a toy.
[22:29:50] <PetefromTn_> Cost Is ALWAYS an object for me but I want to do things correctly as much as possible
[22:30:14] <Tom_itx> if i were going into production, i'd be thinking differently too
[22:30:24] <PetefromTn_> how would YOU build this PC stuff power scheme?
[22:30:43] <Tom_itx> i'd go for simplicity
[22:31:05] <PetefromTn_> I agree
[22:31:06] <Tom_itx> get some of those power rails pcw has for the 5v stuff
[22:31:11] <Tom_itx> din mount
[22:31:14] <Tom_itx> if you want
[22:31:27] <PetefromTn_> what power rails?
[22:33:25] <Tom_itx> looking.
[22:36:39] <Tom_itx> http://store.mesanet.com/index.php?route=product/product&filter_name=common+block&product_id=230
[22:37:02] <PetefromTn_> do you see anything wrong with getting those din rail mount power supplies, DC24v 120watt and 12v60watt and the picopsu 12v 24pin?
[22:37:02] <Tom_itx> with a couple din mounts for them
[22:37:17] <Tom_itx> i don't see why they wouldn't work
[22:37:58] <PetefromTn_> if the monitor is indeed AC then 60watt should be more than enough for the pC I would think?
[22:38:19] <Tom_itx> http://store.mesanet.com/index.php?route=product/product&filter_name=din+rail&product_id=229
[22:38:29] <Tom_itx> you can get extra din rail mounts there too
[22:38:36] <Tom_itx> for those common blocks
[22:39:00] <PetefromTn_> yeah I THINK I have them here for the 7i77 card
[22:39:09] <PetefromTn_> I used them in the Cincinatti too very nice
[22:39:10] <Tom_itx> i drew one up and had it printed for something else i was doing
[22:39:35] <Tom_itx> i put all my stuff on rails now
[22:39:51] <Tom_itx> even found some fuseblocks din mount
[22:40:37] <Tom_itx> got some of that stuff locally though
[22:40:41] <PetefromTn_> yeah I have a BUNCH of fuse blocks and circuit breakers in din mount here as well as the relays and contactors etc.
[22:41:03] <PetefromTn_> would like to use Din mount power supplies as well
[22:41:20] <PetefromTn_> I think that is a reasonable setup tho
[22:41:37] <PetefromTn_> they sell a 100watt 12v one too for another 20 bucks or so
[22:41:49] <Tom_itx> you should have ample room for it all in the enclosure
[22:41:59] <PetefromTn_> http://www.automationdirect.com/adc/Shopping/Catalog/Power_Products_(Electrical)/DC_Power_Supplies/5VDC,_12VDC,_48VDC,_DIN_Rail_Mount/PSB12-100
[22:42:02] <Tom_itx> make sure you isolate things for noise
[22:42:17] <PetefromTn_> oh yeah man there is TONS of room in there for everything
[22:43:07] <Tom_itx> they give you cad drawings for those too
[22:43:11] <PetefromTn_> I plan to put the VFD down near the bottom of the cabinet, the drives in the middle, and the rest of the stuff at the top
[22:43:53] <PetefromTn_> makes sense because the main spindle motor is down near the bottom of the base of the machine and the power leads go thru from underneath the electronics enclosure
[22:44:46] <Tom_itx> early day tomorrow.. later
[22:44:55] <PetefromTn_> thanks man good night
[23:22:15] <MacGalempsy> evening everyone
[23:28:08] <R2E4> evening
[23:29:43] <MacGalempsy> anything exciting going on?
[23:29:59] <ssi> sserial code
[23:32:04] <MacGalempsy> that doesnt sound exciting
[23:32:09] <ssi> you'd be surprised :)
[23:34:04] <MacGalempsy> exciting as keeping you thinking?
[23:34:14] <ssi> wat
[23:34:23] <ssi> it's actually exciting
[23:34:36] <ssi> I just wrapped up a new scheme for building the tocs and memory space of the remote, and I'm pleased with myself
[23:35:07] <MacGalempsy> i working on some 3d printer estimates. I got a phone interview with a school district about getting printers in the classrooms
[23:35:20] <ssi> what sort of printers are you getting for them
[23:35:48] <MacGalempsy> well, it is more of a seminar where we end up building one in class.
[23:36:07] <ssi> so one of the prusa variants then I guess? or what
[23:36:25] <MacGalempsy> trying to get three price ranges. prusa i3, somehting similar with extruded aluminum and maybe a kossel
[23:36:46] <ssi> kossel aka "rip off ssi"
[23:36:59] <MacGalempsy> figure good price points will be $799, $999, and $1399
[23:37:14] <MacGalempsy> that is the class, a printer and 2 rolls of filament
[23:37:33] <ssi> that's pretty cool
[23:37:35] <MacGalempsy> didnt know that kossel was a ripoff ssi
[23:37:51] <ssi> heheh I did the first rostock-style delta built with extrusion
[23:37:54] <MacGalempsy> the main point is getting them lined up with zero prior experience
[23:37:58] <ssi> but I didn't really pursue it
[23:38:07] <MacGalempsy> nice
[23:38:48] <MacGalempsy> the hopes is to target 3 markets here: university students, school districts, and walmart corporates
[23:38:59] <MacGalempsy> workers, not the company
[23:39:30] <MacGalempsy> just trying to get the wholesale costs down in the next few days, then build three models to demo
[23:40:06] <MacGalempsy> with the prusa i3, it would be nice to do a single build plate in 1.8" aluminum
[23:40:10] <MacGalempsy> 1/8"
[23:40:11] <MacGalempsy> heh
[23:41:10] <MacGalempsy> but the cheapest frame I can find at the moment is like $75 for the frame and platform. if anyone here wants to give me an estimate for 12 framesets, lets talk!
[23:43:08] <ssi> lol
[23:44:07] <MacGalempsy> the rest of the stuff I can source pretty easily.
