[01:43:52] <rootB> hello
[02:32:02] <Valen> renesis: minimal physical dimensions are my ideal
[02:32:13] <Valen> a well made array of matched red emitters would be ideal
[02:34:56] <renesis> do you know how to do thermal maths for electronic parts?
[02:35:18] <renesis> you need to figure out your ambient temp and max operational part temp
[02:38:01] <renesis> that delta is what you use for the C/W calculation, you take the Rth for junction to case, add that to the Rth for the heatsink, and use that summed C/W for temp rise
[02:39:01] <renesis> for example, you have a 30W dissipation LED with a Rth juunction to case of 0.5 C/W, ambient of 25C, max operational temp of 85C
[02:39:46] <renesis> so you delta is 60C, divided by 30W is 2 C/W
[02:40:23] <renesis> subtract your LED's Rth of 0.5, and the remaining 1.5 C/W is the maximum Rth of your heatsink
[02:41:11] <renesis> put the Rth into the heatsink calculator, and itll have suggestions of extrusion profile dimensions and lengths
[02:41:27] <renesis> use those dimensions to figure out what you need to buy on ebay
[02:41:42] <renesis> or scavenge
[02:43:16] <renesis> if you have a chassis mount heatsink resistor with a low Rth, you can use that to test a heatsinks Rth
[02:43:17] <Valen> its going to be run connected to an Al heatsink for periods of about .1 second per few seconds
[02:43:32] <Valen> thermal considerations are not high on my list at the moment ;->
[02:43:59] <renesis> measure heatsink ambient temp, mount resistor, burn a watt in it, wait until heatsink temp stabilizes, and the temp rise is your C/W
[02:44:45] <renesis> you can usually use average power dissipation for heatsink calcs, thermal stuff is pretty slow
[02:45:14] <Valen> yeah, I'm not really concerned at all, its going to effectivley be liquid cooled
[02:45:26] <Valen> and I'm happy to modulate duty cycle to limit temperature
[02:46:32] <renesis> big hammer solutions are best for prototype stuff, heh
[02:47:01] <renesis> and yeah if youre not exceeding LED spec and youre doing temp feedback, you can get away with pretty tiny heatsink
[02:47:37] <Valen> but yeah finding the LED is the trick
[02:47:43] <renesis> also remember ambient temps do not mean room ambient temps, its the local ambient temp
[02:48:06] <renesis> like if you have two resistors right next to each other, the operation temp of one is pretty much the ambient temp of the other
[02:48:19] <Valen> I do get paid to design electronics yaknow ;->
[02:48:22] <Valen> http://www.ebay.com.au/itm/LOTS-10W-20W-30W-50W-100W-RGB-SMD-Bright-High-Power-LED-Chips-Flood-Light-Bulb-/191533898420?
[02:48:27] <renesis> yeah i dunno
[02:48:49] <Valen> I got one of those in red but I'm pretty sure its just a bunch of white LED's with red crap poured over it
[02:49:00] <renesis> heh
[02:49:49] <renesis> yeah they all got the same Vf ranges
[02:50:18] <Valen> I figured they added more led's to get the wattage up and use the same driver
[02:50:33] <Valen> I feel I overestimated them :-<
[02:51:51] <Valen> I could spend $100 on 20 odd of these, http://au.element14.com/osram/lrw5sn/led-smd-4-6w-red/dp/1244088
[02:52:08] <Valen> which is the cheapest E14 has for high output red LED's
[02:53:10] <renesis> yeah was kinda surprised the price hasnt dropped very much
[02:53:48] <Valen> I think all the demand is in white
[02:54:04] <Valen> E14 is also super expensive
[02:54:22] <Valen> on the plus side a string of 20 of those is drivable from my lab supply
[02:55:04] <renesis> id trust the osram part way more than superchina high power LED
[02:55:23] <renesis> the osram part has a datasheet, and a C/W spec
[02:56:41] <Valen> yeah, its also 10x the price though and I still need to make a PCB and driver ;->
[02:57:17] <renesis> ya =\
[03:00:21] <Deejay> moin
[03:05:30] <Valen> crap now this is a LED http://www.luminus.com/products/Luminus_CBT120_Datasheet.pdf
[03:05:36] <Valen> 18A, single chip
[03:05:44] <Valen> 30A pulsed
[04:22:13] <SpeedEvil> _dire_ efficiency though
[04:23:09] <SpeedEvil> 7.2W out for 70 in on blue, And half that on green and red
[04:23:39] <SpeedEvil> Ah - 2011
[04:48:24] <gonzo_> Morning peoples
[04:48:24] <gonzo_> I have a 7i90-sample configs issue that I would appreciate some guidence on
[04:49:38] <gonzo_> I have a 7i90-sample configs issue that I would appreciate some guidence on
[04:49:39] <gonzo_> have loaded the fpga up with what an EPP image that has enough steppers, trying with the simple stepper sample configs that comes with the install. Trying to run I get an error when the .hal file gets to adding the hm2_7i90.0.read thread
[04:49:59] <gonzo_> Can anyone point me in a sensible direction....
[05:07:57] <XXCoder> evil speed
[06:02:51] <alex_joni> gonzo_: can you paste the error?
[06:15:09] <gonzo_> alex_joni, will do later. Not at the machine at the mo
[07:14:26] <Jymmm> Any thoughts on sending text to a manual typewriter?
[07:15:15] <Tom_itx> tty
[07:16:00] <Jymmm> As in making a manual typewriter digital
[07:16:31] <Jymmm> cam action?
[07:17:19] <Jymmm> http://uniqcode.com/typewriter/
[07:18:13] <Jymmm> Tom_itx: CNC Fingers?
[07:18:39] <Tom_itx> build robotic hands and program them to recognize the quwerty kbd
[07:18:48] <Jymmm> solenoids?
[07:18:55] <Tom_itx> of course
[07:19:01] <Tom_itx> or hydraulic rams
[07:19:07] <Tom_itx> want a heavy touch??
[07:19:13] <archivist_herron> get an old golf ball typewriter
[07:19:16] <Jymmm> maybe =)
[07:19:44] <Tom_itx> yeah you'd be better off with a 'newer' older typewriter
[07:20:48] <archivist_herron> considering the golfball was available with a keyboard and also worked as a printer
[07:21:12] <Jymmm> archivist_herron: I never saw them used as a pritner before
[07:21:25] <Tom_itx> http://www.usbtypewriter.com/
[07:22:07] <Tom_itx> 'easy install kit'
[07:22:08] <Tom_itx> haha
[07:22:49] <Jymmm> SO close
[07:22:50] <archivist_herron> https://en.wikipedia.org/wiki/IBM_Selectric_typewriter
[07:23:19] <Jymmm> Ah... "Selectric-based machines with data storage" I never knew that
[07:23:39] <Tom_itx> yeah
[07:24:19] <Jymmm> Tom_itx: Now find the opposite kit, and we'll be good =)
[07:24:59] <Tom_itx> http://www.vintage-computer.com/vcforum/showthread.php?23266-Interfacing-IBM-Selectric-to-IO-Port
[07:26:12] <Tom_itx> https://groups.google.com/forum/#!topic/alt.folklore.computers/M7H9LZrK894
[07:26:50] <Jymmm> Not golfball, need the look of manual typewriter
[07:27:25] <Jymmm> offset characters, different levels of impression, etc
[07:27:29] <malcom2073_> Hmm, what do people use for dxf to gcode conversion?
[07:27:43] <Jymmm> dxf2gcode
[07:27:49] <Tom_itx> serial killer work?
[07:28:34] <malcom2073_> Jymmm: Thanks, trying it now
[07:28:54] <Jymmm> Tom_itx: crafter's thing; ppl are paying good money for "hand typed manual" notes and letters
[07:29:05] <malcom2073_> Wait, what? Why?
[07:29:11] <malcom2073_> Oh, crafters heh
[07:29:34] <Tom_itx> fake notes n letters...
[07:29:53] <malcom2073_> Distressed retro
[07:29:55] <Jymmm> a 50's thing
[07:31:13] <Tom_itx> get an old teletype machine and you'll have the interface
[07:31:21] <Jymmm> I'm just not sure which approach to automate this http://common.ziffdavisinternet.com/encyclopedia_images/_BLICK5.JPG
[07:34:23] <malcom2073_> Jymmm: dxf2gcode looks like it'll work great, thanks!
[07:38:13] <Tom_itx> http://numist.net/post/2010/project-typewriter.html
[07:41:56] <archivist_herron> get a mechanical turk to use the typewriter
[07:43:14] <Tom_itx> Jymmm: http://liliputing.com/2015/06/turning-a-classic-typewriter-into-a-printer.html
[07:52:38] <malcom2073_> http://i.imgur.com/eUTani9.png
[09:32:49] <MattyMatt> Tom_itx, you could buy those in the 1980s
[09:33:02] <MattyMatt> for IBM selectrics
[09:33:30] <MattyMatt> cheaper than a daisywheel
[09:34:39] <CaptHindsight> Tom_itx: is that a kickstarter?
[09:36:22] <MattyMatt> where would you get the typewriters?
[09:37:13] <MattyMatt> the last factory only closed a couple of years ago, so there's probably a warehouse somewhere
[09:37:53] <CaptHindsight> send one to China, wait a few months, order from Aliexpress
[09:38:36] <Jymmm> CaptHindsight: QWEMTY
[09:38:39] <ssi> "But mostly, it’s just kind of a useless, expensive, and awesome project."
[09:38:49] <ssi> that pretty much sums up the maker lifestyle
[09:39:01] <MattyMatt> http://www.aliexpress.com/item/Wholesale-16pcs-lot-2-colors-Vintage-ZAKKA-Style-Wooden-typewriter-Card-Holder-Messager-holder-Free-shipping/1090185649.html
[09:39:52] <MattyMatt> I just want a typewriter keyboard that crumbs and ash fall through
[09:40:34] <Jymmm> MattyMatt: That's called a pencil
[09:40:43] <archivist> I have biannual cap lifting and crumb removal on this kb
[09:41:02] <archivist> I wait till there is a meal
[09:41:05] <Jymmm> toss in dishwasher
[09:41:11] <CaptHindsight> Jymmm: just saw a QZERTY version on etsy
[09:41:21] <Jymmm> CaptHindsight: =)
[09:41:43] <MattyMatt> bio laundry powder gets the human detritus off
[09:42:35] <MattyMatt> model M is riveted together inside, so I don't soak the whole thing
[09:43:42] <CaptHindsight> looks like Rover typewriters are still in production
[09:44:04] <CaptHindsight> http://www.alibaba.com/product-detail/18-manual-typewriter_334933839.html
[09:44:08] <MattyMatt> they probably already have rs232/usb already
[09:44:24] <MattyMatt> aha a proper manual
[09:44:55] <MattyMatt> good luck getting consistent pressure with solenoids
[09:46:56] <CaptHindsight> you'd think that there would be some kind of photo-paper to make hard copy right from a computer screen
[09:47:09] <CaptHindsight> probably faster than typing
[09:47:19] <archivist> a camera
[09:47:46] <archivist> actually we used to make a screen grabber for that job
[09:47:59] <archivist> I have the guts of a couple here
[09:48:18] <MattyMatt> ZX printer wasn't far off
[09:48:30] <CaptHindsight> they used to be called film scanners here, yes sounds backwards
[09:48:47] <CaptHindsight> crt to film
[09:49:02] <MattyMatt> that's all done with lasers now
[09:49:16] <MattyMatt> direct output to 35mm
[09:49:48] <MattyMatt> even original Tron was 4k pixels across
[09:50:02] <archivist> CaptHindsight, ours grabbed the vga/whatever and printed to out colour inkjet
[09:50:14] <MattyMatt> or 2k. memory ages
[09:50:31] <archivist> the VCO in it was fun
[09:52:05] <Jymmm> MattyMatt: That's the whole thing, you dont want consistant pressure
[09:52:40] <MattyMatt> you need a good swing. a manual typewriter is a piano
[09:53:20] * MattyMatt replaces platen with xylophone
[09:53:48] <CaptHindsight> variable pressure for musical instruments
[09:55:17] <MattyMatt> an electric typewriter tho, you just need a few mm of displacement and the rest of the cycle just happens. on IBM you could feel the key being sucked under your finger
[09:56:17] <CaptHindsight> did anyone computer keyboards with the same action?
[09:56:29] <CaptHindsight> did IBM?
[09:56:46] <MattyMatt> nope. model M is the closest. clicky
[09:57:11] <MattyMatt> it's still you providing all the downward pressure tho
[09:59:59] <MattyMatt> a near vertical keyboard with angled keys might be nicer to type at than a completely flat vertical one
[10:00:19] <MattyMatt> no stubbing your fingertips
[10:01:45] <MattyMatt> now there's a good reason for 3d printers to exist
[10:02:00] <MattyMatt> on my desk just over there even
[10:02:19] <MattyMatt> yay, 2 more weeks in blender for no good reson
[10:02:50] * MattyMatt prototypes in cardboard
[10:09:32] <malcom2073_> lol
[10:09:47] <malcom2073_> I dunno
[10:11:14] <CaptHindsight> malcom2073_: what size light bulb did you decide to go with for the lathe?
[10:11:25] <malcom2073_> CaptHindsight: I didn't yet.
[10:11:42] <Jymmm> ONE MILLION WATT LIGHTBULB, and a small diet soda!
[10:11:53] <malcom2073_> Dem calories
[10:12:39] <Jymmm> I suggest a 1000W HPS bulb =)
[10:12:49] <CaptHindsight> Jymmm needs to find a use for IPA's since most are undrinkable
[10:13:16] <Jymmm> CaptHindsight: Dutch oven ribs
[10:13:43] <Jymmm> CaptHindsight: Beer chicken
[10:17:33] <FinboySlick> On the topic of good mechanical keyboards though. WASD keyboards give you a very nice choice of switches, some very similar to Model M.
[10:20:52] <FinboySlick> They're beefy too, mine is over a kilogram.
[10:29:04] <malcom2073_> Hmm, I wonder if drilling ventilation holes would help, the garage is a concrete box, so it's not like the air has anywhere to go
[10:30:25] <archivist> no ventilation, you die
[10:30:38] <malcom2073_> Well the doors are leaky enough that I don't die
[10:31:01] <archivist> but, damp is not good for machines
[10:31:32] <malcom2073_> Was looking at options for sealing the concrete ceiling, since it's a patio above, and some of it is likely coming from there
[10:31:45] <archivist> I spent some time this year making the garage less damp
[10:35:07] <malcom2073_> yeah?
[10:35:16] <SpeedEvil> malcom2073_: If you actually seal the garage 100%, then you can dehumidify it.
[10:35:32] <SpeedEvil> Otherwise, it's not going to do much
[10:35:40] <malcom2073_> "do much" is this a 1%, or a 50% thing?
[10:35:57] <SpeedEvil> I assume the walls and ceiling is not clear?
[10:36:05] <SpeedEvil> That is - you can't put insulation on it?
[10:36:17] <malcom2073_> I've insulated one of the walls, the other two I've not yet, not in the budget this year
[10:36:58] <malcom2073_> Tbh I'm gonna tear out one of the sections I did and check for mold growth in another year before I do the rest, I've gotten conflicting advice on how to properly do it, so I'm trying one method heh
[10:38:11] <archivist> I added seals around the doors
[10:39:07] <Jymmm> malcom2073_: cement ceiling??? In a garage or basement?
[10:39:13] <malcom2073_> Jymmm: Garage, it has a patio above it
[10:39:37] <Jymmm> ciderblock walls?
[10:39:40] <malcom2073_> Yeah
[10:39:46] <Jymmm> sealed?
[10:39:49] <malcom2073_> New
[10:39:50] <malcom2073_> newp
[10:39:58] <Jymmm> got Ho?
[10:40:04] <malcom2073_> Ho?
[10:40:08] <Jymmm> backho
[10:40:14] <malcom2073_> It's aboveground
[10:40:16] <malcom2073_> well, half of it is
[10:40:56] <malcom2073_> About half of one wall is underground, one is attached to the basement of the house, one is above ground, and one is garage doors
[10:41:31] <Jymmm> malcom2073_: https://www.youtube.com/watch?v=myOcoGEcMCE
[10:41:52] <malcom2073_> That stops wind driven rain, I'm not getting leaking
[10:42:06] <malcom2073_> And mostly from the floor/ceiling
[10:42:24] <malcom2073_> That's nifty though
[10:42:54] <Jymmm> Well, suck vid, but you need the masonary waterproof paint
[10:43:05] <Jymmm> the thick shit =)
[10:43:53] <malcom2073_> I'm finding conflicting information on if I can waterproof paint/epoxy the inside of a concrete slab
[10:44:19] <MattyMatt> of course you can
[10:44:33] <malcom2073_> MattyMatt: That's what some people say, indeed
[10:44:38] <MattyMatt> if you buy Our Product™
[10:44:42] <malcom2073_> heh
[10:45:11] <MattyMatt> floor leveling compound is epoxy
[10:45:19] <SpeedEvil> Epoxying or otherwise coating the inside of the structure is not an issue.
[10:45:45] <SpeedEvil> The issue is will interstitial condensation build up moisture behind the coating in such a manner to damage the structure,
[10:46:02] <SpeedEvil> And will condensation on the cold walls cause issue.
[10:46:10] <malcom2073_> SpeedEvil: It will, the ceiling is open on the other side
[10:46:19] <SpeedEvil> you almost certainly want insulation with a small air gap behind it.
[10:46:30] <malcom2073_> Yeah, I'm going to insulate the walls
[10:46:41] <SpeedEvil> All the way around - if you want to actually insulate - and ventilate the airgap
[10:47:04] <malcom2073_> There's an idea, put vents at the top of the wall all the way around
[10:47:13] <malcom2073_> Since there's no attic to facilitate airflow
[10:47:21] <malcom2073_> behind the wall
[10:48:00] <SpeedEvil> Or a small fan, and vented pipe to keep the rear dry
[10:48:17] <MattyMatt> a core of breeze blocks would provide the air gap in a wall
[10:49:01] <malcom2073_> MattyMatt: That's what the walls are made out of
[10:49:29] <ssi> https://pbs.twimg.com/media/CSfplcvUwAEgHrQ.jpg:large
[10:49:31] <ssi> yasssssss
[10:49:41] <malcom2073_> ssi: sexy
[10:49:45] <MattyMatt> so where's the slab? on the floor?
[10:50:01] <malcom2073_> MattyMatt: And ceiling
[10:50:42] <MattyMatt> ah right
[10:52:22] <CaptHindsight> whats better sockets or wrenches?
[10:52:49] <ssi> CaptHindsight: hammers
[10:52:57] <MattyMatt> 6 sided sockets
[10:53:13] <MattyMatt> if you have the choice
[10:53:29] <SpeedEvil> Wenches
[10:53:38] <MattyMatt> with wrenches.com
[10:53:41] <malcom2073_> Depends on the job
[10:54:49] <MattyMatt> if there's no other consideration. 6 sided socket is the kindest to the nut
[10:56:19] <ssi> in that drawer, I have 6-pt shallow, semi-deep, and deep, plus low profile 12pt, plus swivel shallow 12pt
[10:56:24] <ssi> all 1/4 drive snapon
[10:56:32] <MattyMatt> naturally
[10:56:50] <ssi> those swivel sockets have saved my ass
[10:57:00] <ssi> I actually had to borrow a set to get a job done a couple months ago, and I bought them after that
[10:57:29] <MattyMatt> maniple fields exist
[10:57:41] <ssi> maniple fields?
[10:57:42] <MattyMatt> like what the drones use in the culture
[10:58:23] <MattyMatt> http://www.bbc.co.uk/news/science-environment-34647921
[10:59:17] <ssi> o
[10:59:21] <MattyMatt> Snapon Sonic coming soon :)
[10:59:48] <MattyMatt> a single tool that does it all. they'll love that
[11:02:10] <MattyMatt> for the really stubborn nuts, GM japanese knotweed, while we're talking sci-fi
[11:08:43] <Jymmm> I have a 1/4" snapon set that looks like this... LOVE THOSE THINGS http://www.ebay.com/itm/Snap-On-1-4-Drive-6-Point-Deep-Socket-Set-110STMY-10-Piece-3-16-9-16-New-Logo/131623963579
[11:09:27] <ssi> Jymmm: yea that's the set I have, but it's in the red magnet tray which I love
[11:09:54] <Jymmm> I like the snap tray, as that set goes everywhere
[11:18:43] <bjm_> Any opinions on a Logan 200 Series for CNC conversion? http://flint.craigslist.org/tls/5273831846.html
[11:20:44] <cradek> nah
[11:23:23] <archivist> looks like a southbend copy
[11:23:58] <cradek> I don't think cnc would make that lathe much more useful than it is
[11:24:18] <archivist> I keep my southbend manual :)
[11:24:47] <cradek> how would you change tools or change spindle speed or drill or tap?
[11:25:15] <bjm_> Kind of my opinion also, but I saw that price in my daily craigslist search so i figured I'd ask.
[11:25:33] <archivist> get it for your manual machine
[11:28:22] <ssi> not really the best manual machine either
[11:29:20] <cradek> meant for doing basic one-off things at a home or farm shop
[11:29:21] <archivist> better than none at all
[11:29:27] <ssi> sure
[11:29:41] <archivist> cant beat manual for one off
[11:29:52] <cradek> hopefully that bucket is full of the other change gears
[11:30:22] <bjm_> I have a little 7x10 manual that really needs an upgrade, but I think I'd rather save up and get something nicer
[11:30:51] <pcw_home> At least they are metal gears, not plastic like my rubbery HF
[11:32:05] <cradek> can't tell if it has a threading dial
[11:32:14] <cradek> surely it does?
[11:33:01] <archivist> on the southbend it is an add on
[11:36:09] <archivist> http://www.lathe.com/models.htm
[12:17:29] <MattyMatt> I still don't regret getting a lathe without change gears, as I do mostly metric threads
[12:18:03] <MattyMatt> still with taps and dies, until I get cnc on my little lathe
[12:19:36] <MattyMatt> just one axis to start. stepper on the leadscrew and encoder on the spindle. I might run it on an arduino with a little LCD to set a simple feedrate
[12:22:45] <MattyMatt> cnc on the compound would be handy too, because these threads might be tapered or in ptfe where a relief channel becomes a stress riser
[12:28:12] <MattyMatt> plan B is still to scratchbuild a full cnc slantbed, but I'm holding off until I can make it in metal
[12:28:34] <MattyMatt> I could call the plywood version a prototype I guess :)
[12:30:03] <MattyMatt> this is a small lathe I'm talking about 5x12 approx
[12:30:55] <zeeshan|2> cute lathe.
[12:31:45] <MattyMatt> my current one is about that size too http://imgur.com/a/piCdr#4
[12:32:53] <zeeshan|2> i like your model of a chuck :)
[12:34:07] <MattyMatt> measurements taken from my real one
[12:34:45] <MattyMatt> I've got the whole lathe modelled just about
[12:35:30] <ssi> zeeeee
[12:35:58] <ssi> zeeshan|2: more tools came in, reorganizing the box
[12:36:09] <ssi> zeeshan|2: https://pbs.twimg.com/media/CSf7bWrXAAAyj0O.jpg:large https://pbs.twimg.com/media/CSf7hw3WoAAL6OL.jpg:large https://pbs.twimg.com/media/CSf7iiXWcAQMTtq.jpg:large
[12:36:14] <MattyMatt> I need to do the chuck as a parametric script, for any size, non-whitworth screws, 7 jaw option etc
[12:36:20] <ssi> all the sheet metal tools were in a long drawer, I consolidated them to a short drawer
[12:37:42] <MattyMatt> my spanner drawer was intended for cutlery. green felt lining tho
[12:37:56] <zeeshan|2> NICE
[12:38:00] <zeeshan|2> er caps
[12:38:07] <ssi> it's caps appropriate :D
[12:38:39] <zeeshan|2> how much did that drawer full of tools cost? 100000?
[12:38:40] <zeeshan|2> :)
[12:38:48] <ssi> ugh it wasn't cheap :)
[12:38:50] <ssi> wasn't quite 100k
[12:39:15] <ssi> oh god you're gonna make my ocd do something else horrible:
[12:39:24] <ssi> spreadsheet of everything in the toolbox, part numbers, and list prices
[12:39:28] <zeeshan|2> id like a wrench set from snapon
[12:39:30] <zeeshan|2> rofl
[12:39:34] <ssi> I have a second set coming
[12:39:37] <zeeshan|2> dude i started on one drawer
[12:39:40] <ssi> I found another good deal after I got the first one
[12:39:46] <MattyMatt> for 100k you could take a year off work, buy a forge, learn to forge, build a drop hammer, etc etc etc
[12:39:48] <zeeshan|2> and stopped half way for my machinist tools
[12:39:49] <ssi> and I may sell whichever set I'm less happy with
[12:40:03] <zeeshan|2> how much is the wrench set?
[12:40:05] <zeeshan|2> typically
[12:40:44] <MattyMatt> all the nice girls like a blacksmith
[12:40:46] <ssi> a lot :P
[12:40:49] <ssi> http://buy1.snapon.com/catalog/item.asp?P65=&tool=all&item_ID=633147&group_ID=674992&store=snapon-store&dir=catalog
[12:40:55] <ssi> 3/8-1 is $438
[12:41:07] <ssi> plus I added downward, 11/32 5/16 1/4
[12:41:16] <zeeshan|2> i mean used
[12:41:26] <zeeshan|2> those prices arent even what the snapon truck charges
[12:41:27] <zeeshan|2> :P
[12:41:31] <ssi> I got the first 3/8-1 set for about $220
[12:41:43] <ssi> and then like $15 apiece for the bottom three
[12:41:45] <ssi> so sub-300
[12:41:53] <ssi> the second set was 1/4-1 and I got it for $200
[12:41:56] <ssi> which is why I jumped on it :P
[12:42:18] <ssi> plus I bought a set of angle wrenches in standard and metric
[12:42:30] <anomynous> metric is standard
[12:42:32] <anomynous> duh
[12:42:34] <ssi> :)
[12:42:39] <ssi> http://www.ebay.com/itm/221920668806?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
[12:42:43] <ssi> those tend to sell for about 215
[12:42:49] <ssi> again, got them for 175, had to jump on it
[12:43:10] <ssi> every A&P I've ever known has lusted after angle wrenches, if they didn't already have some :P
[12:44:01] <anomynous> i maded a keyway into a few ballscrews and drilled holes and emptied trash cans and drove a forklift and drank coffee and what else.
[12:44:19] <ssi> yay productivity :)
[12:44:33] <anomynous> and ate cake
[12:44:35] <ssi> zeeshan|2: what's your opinion on tool finish? chrome, industrial black oxide, what do you like
[12:44:37] <anomynous> we had cake at work
[12:44:37] <zeeshan|2> those are brand new..
[12:44:43] <ssi> yes, exactly
[12:44:56] <zeeshan|2> they are cheap used
[12:45:06] <ssi> not much cheaper
[12:45:14] <ssi> I've been watching some used sets, they get high at the end
[12:45:18] <MattyMatt> I want colour coded sockets
[12:45:29] <ssi> I bought a used set of standard angle wrenches for BJ
[12:45:32] <ssi> I think it ended up at 155
[12:45:33] <zeeshan|2> i like the crinkled finish
[12:45:37] <zeeshan|2> it looks like microshot blasting
[12:45:43] <anomynous> colour coded sockets? what for?
[12:45:48] <ssi> what brand?
[12:45:54] <zeeshan|2> proto
[12:46:11] <MattyMatt> like resistor colour codes. size and metricity in 2 or 3 bands
[12:46:25] <ssi> I've never used proto stuff
[12:46:33] <ssi> MattyMatt: harbor freight sells color coded sockets :P
[12:46:48] <MattyMatt> yay. tell them to open a store in UK
[12:46:55] <ssi> http://www.harborfreight.com/10-piece-3-8-eighth-inch-metric-deep-wall-color-coded-socket-set-93265.html
[12:46:55] <MattyMatt> I'll be waiting
[12:47:01] <ssi> for that money you can have them shipped :)
[12:47:17] <CaptHindsight> MattyMatt: don't they already sell crap tools in the UK?
[12:47:21] <ssi> :D
[12:48:08] <MattyMatt> only in metric. if you want imperial you have to scrape the rust off a dead man's tools
[12:48:17] <ssi> I wonder how well this works
[12:48:17] <ssi> https://store.snapon.com/Magnetic-Wrench-Organizers-Holder-Wrench-Magnetic-1-4-to-1-Blue-P646409.aspx
[12:48:39] <anomynous> why dont you add paint to your sockets yourself?
[12:48:51] <MattyMatt> it'd wear off too quick
[12:48:51] <ssi> probably won't hold up very lonhg
[12:49:03] <anomynous> put them in lathe and make little grooves
[12:49:10] <ssi> that's not a bad idea :P
[12:49:14] <ssi> or just fill the engraving with differetn colors
[12:49:25] <MattyMatt> I'll get a carbide engraving bit and freshen up the stamped numbers
[12:49:37] <MattyMatt> then fill with paint
[12:49:51] <ssi> zeeshan|2: oh I forgot I got metric wrenches too: http://www.ebay.com/itm/131636197418?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
[12:49:59] <ssi> they haven't come yet
[12:50:52] <MattyMatt> if I didn't store my sockets loose, I'd be less worried about reading them easily I guess
[12:51:26] <ssi> yea I can't deal with loose sockets
[12:51:28] <ssi> drives me nuts
[12:51:36] <anomynous> why dont everyone just start using allen keys and forget everything else
[12:51:36] <MattyMatt> I got 2 sweet drill index today. old british ones in 1/64 up to 1/2
[12:52:06] <ssi> anomynous: you'd like that wouldn't you.... Mr ALLEN
[12:52:11] <ssi> yea I see through your anonymous disguise
[12:52:23] <anomynous> no. Fewer tools that way
[12:52:32] <anomynous> theres always too many tools lying around
[12:52:33] <anomynous> ;D
[12:52:40] <MattyMatt> now I need drills in 1/64 and a handy metric conversion table, because at those sizes I think in mm
[12:52:44] <archivist> some jobs hex is useless
[12:52:56] <ssi> tool organization and tool control is definitely a challenging problem
[12:53:03] <anomynous> yes, it is
[12:53:23] <zeeshan|2> lol @ allen on a car application
[12:53:31] <zeeshan|2> there would be a lot more bolt ownage
[12:53:38] <zeeshan|2> w/ all the crud inside the head
[12:53:41] <anomynous> when you are under a car and you want a wrench you always notice you didnt take THAT size with you
[12:53:43] <zeeshan|2> rotting the bolt head from inside out
[12:53:48] <archivist> lost tool, get a new one, instantly old one returns to top of pile
[12:53:50] <anomynous> then you come out
[12:53:54] <anomynous> and repeat
[12:54:05] <zeeshan|2> there is a reason why cars used external hex
[12:54:52] <ssi> archivist: part of the reason I'm spending all this money upgrading my crap to snapon is because i have a direct correlation of tool price to tool retention
[12:55:03] <ssi> the more I pay for something the harder I work to keep it organized and not lost :P
[12:55:25] <archivist> hehe
[12:55:38] <anomynous> i want to sell something for you. I can make it cheap and it never breaks if I ask enough money for it.
[12:55:43] <archivist> I know that does not always work
[12:56:09] <MattyMatt> it's my bench space I covet, when I'm spurred to organise
[12:56:21] <ssi> bench space is also a hard problem
[12:56:25] <MattyMatt> old tools look rather good on the wall in neat rows too
[12:56:32] <ssi> I have hundreds of square feet of bench, none of it usable :)
[12:56:37] <archivist> often you put expensive away safely.....but where was that "away"
[12:56:53] <ssi> I made a little bit of bench space to do electronics work this week
[12:56:54] <ssi> https://pbs.twimg.com/media/CSXAHomXAAA4UQK.jpg:large
[12:56:57] <archivist> took nearly a month to find one file
[12:57:13] <ssi> archivist: files are in this drawer! https://pbs.twimg.com/media/CSf7iiXWcAQMTtq.jpg:large
[12:57:24] <ssi> there's more files in the machinists toolbox by the lathe
[12:57:26] <ssi> but you get the idea :)
[12:57:37] <ssi> both my vixen files are in that drawer though
[12:57:38] <malcom2073_> I need to get a big rolling toolbox one of these days
[12:57:45] <anomynous> what are those things above pliers on left
[12:57:49] <ssi> malcom2073_: I'm really happy with htis one, and it's actually harbor freight
[12:57:49] <MattyMatt> RFID is probably the only answer, combined with cameras in every room to watch where you take everything
[12:57:55] <ssi> anomynous: cleco clamps
[12:58:04] <archivist> I have draws and boxes full of files, but I would never put the pivot file in those boxes
[12:58:22] <ssi> archivist: get a plastic tube like a reamer comes in for your pivot file :)
[12:58:32] <ssi> malcom2073_: http://www.harborfreight.com/56-in-11-drawer-glossy-red-industrial-roller-cabinet-67681.html
[12:58:41] <ssi> malcom2073_: they make a 72" that has a left set of short drawers as well
[12:58:42] <ssi> but I got the 56
[12:58:59] <archivist> the file came in a tub, soon got lost as that file usually remains on the clockmaking lathe
[12:59:09] <MattyMatt> last time I looked. HF doesn't ship to UK. not their $29 chuck at least
[12:59:29] <ssi> I'm not yet crazy enough to pay for a snapon toolbox :P
[12:59:49] <ssi> one day I'll find someone panic selling a box with tools in it on craigslist or something and I'll snap it up
[13:00:41] <archivist> I cannot imaging an electronics bench that empty :)
[13:00:55] <archivist> imagine even
[13:00:55] <andypugh> Was this deliberate? ssi: yea I can't deal with loose sockets
[13:00:55] <andypugh> [5:27pm] ssi: drives me nuts
[13:01:00] <ssi> archivist: that's just the half next to the computer here that I cleaned off to set up the scope :)
[13:01:07] <MattyMatt> I think every car mechanic wants snapon boxes in his garage, more than good tool
[13:01:07] <ssi> andypugh: NO BUT I WISH IT WAS :D
[13:01:25] <ssi> andypugh: http://www.funniestmemes.com/wp-content/uploads/Funniest_Memes_this-shit-drives-me-up-the-fucking-wall_19963.jpeg
[13:02:04] <archivist> ssi about as tidy as I get http://www.collection.archivist.info/searchv13.php?searchstr=lounge+electronics
[13:02:17] <ssi> archivist: :D
[13:03:22] <ssi> here's the other half at the moment
[13:03:22] <ssi> https://pbs.twimg.com/media/CSgIW-lUYAERqx0.jpg:large
[13:03:25] <CaptHindsight> there still a few inches of room on the edge for working on a device
[13:03:46] <ssi> there's a clean spot under the microscope! :D
[13:03:57] <CaptHindsight> it's all you need unless it's something big
[13:05:59] <ssi> rene-dev_: wb :)
[13:06:25] <ssi> http://atlanta.craigslist.org/atl/tls/5288941947.html
[13:06:30] <ssi> see like that might be a deal worth snagging
[13:07:01] <malcom2073_> ssi: Yeah I was eyeing up HF's toolboxes when I was there the other day
[13:07:02] <malcom2073_> heh
[13:07:11] <ssi> malcom2073_: I'm actually really impressed with that line of boxes
[13:07:22] <ssi> a mechanic friend of mine here at the airport has had one for awhile, and I always assumed it was a snapon box
[13:07:33] <ssi> when I started talking to him about it, and found out it was HF, I went and bought mine that day
[13:07:45] <malcom2073_> Yeah they have some decent boxes
[13:07:46] <ssi> the only thing I don't like about it, it has plastic locks for the drawers
[13:07:52] <ssi> and they break off within a few uses
[13:07:57] <malcom2073_> Eh, I don't need locks
[13:08:02] <CaptHindsight> I want a set of wrenches with the ~10ft extension handles like in the video jymmm posted https://youtu.be/VfwpF68Di8k?t=3m
[13:08:26] <ssi> not the keylock stuff, there's like a little handle that you pull while you're opening the drawer
[13:08:32] <ssi> keeps the drawrs from opening when you roll it around
[13:08:38] <ssi> the slides still have teh usual detents, but they have the locks as well
[13:08:43] <ssi> they're just junk locks sadly
[13:08:57] <malcom2073_> ah heh
[13:09:41] <ssi> CaptHindsight: what in the world would you do with those?
[13:10:21] <zeeshan|2> can anyone here speak japanese
[13:10:27] <malcom2073_> CaptHindsight: That's awesome
[13:10:30] <malcom2073_> And amazingly scary
[13:11:14] <CaptHindsight> ssi: exhibition wrenching, disassemble an engine from 10 ft away
[13:11:26] <ssi> "exhibition wrenching"
[13:11:39] <ssi> sounds like a spectator sport that not many people would pay to attend :)
[13:11:48] <CaptHindsight> they do it with shooting so why not
[13:11:58] <ssi> fair enough :D
[13:12:11] <Jymmm> ssi: It's got 120KV, of course they'll pay!
[13:12:33] <ssi> as long as there are occasional accidental deaths, people will pay
[13:12:50] <CaptHindsight> 500kv wheel of fortune
[13:12:52] <ssi> holy crap he's running a torque wrench with it
[13:13:01] <Jymmm> lol
[13:14:10] <Jymmm> I like the whole rotating wrenching action
[13:14:15] <ssi> yea
[13:14:55] <malcom2073_> "Now with rotating wrenching action!!!"
[13:15:13] <Jymmm> Funny thing, I never saw a lockout on the control panel
[13:19:38] <Sync> it is not mandatory here
[13:19:38] <andypugh> Jymmm: Why would they need a lockout on the control panel? They were working upstream of it.
[13:19:55] <Sync> well, the grounding bar could come off
[13:19:56] <Jymmm> andypugh: the grounding strip
[13:20:00] <Sync> but that's all in the end
[13:20:10] <Sync> it is grounded on the other side as well
[13:20:11] <Sync> so eh
[13:21:44] <archivist> the bit to carry the lockout is the bit they were going to service
[13:22:43] <Sync> well, not really, at least you are supposed to put a "men working" sign on the grounding bar switch, at least in germany
[13:22:48] <Sync> if there is no secondary safety
[13:22:49] <Jymmm> archivist: The one witht he 120KV 12" arc you mean?
[13:22:59] <Sync> like a switch on the motor line to the grounding bar
[13:23:05] <Sync> so they know nobody fucks with it
[13:23:34] <archivist> yes those wires go to the breaker itself
[13:38:32] <andypugh> The fact that there was an arc seems to suggest that the load was still in place, so presumably it was a transformer and the breaker was on the secondary side.
[13:40:22] <archivist> one gets a lovely arc just with a few pf of capacitance
[13:42:55] <archivist> a thing all TV engineers did in the valve days from the top cap of the eht or efficiency diode to a screw driver hand held, was a simple test to see what state the high voltage supplies were in
[13:52:40] <Sync> andypugh: capacitive coupling
[13:52:48] <Sync> if the load was still there, they'd be dead
[13:53:21] <andypugh> AC. I forgot that part.
[13:55:36] <archivist> works with DC too, you get single cracks as your line/screwdriver charges
[14:52:39] <zeeshan|2> ZAP
[14:54:03] <ssi> zap yoself sucka
[14:55:44] <zeeshan|2> man i need a japanese manual for the rx7
[14:55:51] <zeeshan|2> google aint coming with anything
[14:55:59] <zeeshan|2> its cause im not searching in japanese :{
[14:55:59] <ssi> why a japanese manual
[14:56:10] <zeeshan|2> wiring is completely diff
[14:56:13] <ssi> ug
[14:56:16] <zeeshan|2> well majorly diff
[14:56:31] <zeeshan|2> i dont wanna spend hours trying to figure out each wire =/
[14:57:56] <ssi> don't blame you
[14:58:13] <PetefromTn_> hey folks
[15:00:07] <FinboySlick> Yo Pete.
[15:00:19] <PetefromTn_> Hey slick hows it goin?
[15:07:45] <gonzo_> eve peeps. Mind if I run some silly hal/ini issues passed you all?
[15:08:41] <gonzo_> using the example 7i90 files, I am getting :
[15:09:20] <gonzo_> HAL: ERROR: function 'hm2_7i90.0.read' not found
[15:09:46] <gonzo_> though I know the interface works, as I managed to use mesaflash to load/verify the firmware
[15:09:52] <gonzo_> any clues?
[15:16:54] <PCW> is that the first error? sounds either like the driver didn't load or there's a name issue
[15:20:36] <gonzo_> eve again peter
[15:20:50] <gonzo_> Yep, in the Dubug File Information, that is the first
[15:21:36] <Erant> PCW: Do you guys do first day on USPS? I called yesterday and the lady said my order was being filled. Just curious if I'll be able to make chips this weekend, or if I have to wait 'til next.
[15:23:55] <PCW> we are really behind on shipments so nothing is going to be shipped very soon after an order
[15:24:31] <PCW> gonzo_ what is your parallel port address?
[15:25:03] <PCW> I think the default is 0x378 if unspecified
[15:25:14] <gonzo_> 0x378 I believe (that's what I used for mesaflash)
[15:25:28] <TekniQue> 378 is the address of the first parallel port
[15:25:37] <TekniQue> 3BC is the second IIRC
[15:25:48] <TekniQue> and then the third was 278 wasn't it
[15:26:12] <gonzo_> yep, just checked the mesaflash --verify at that address. All fine
[15:26:57] <gonzo_> I did add ioaddr=0x378 to the .hal file. But made no difference
[15:27:33] <gonzo_> I saw soe reference to adding loadrt epp, but it complained that it could not be found
[15:28:32] <PCW> so if thats the case I would try:
[15:28:33] <PCW> halrun
[15:28:35] <PCW> halcmd: loadrt hostmot2
[15:28:36] <PCW> halcmd: loadrt hm2_7i90
[15:28:38] <PCW> halcmd: show function
[15:28:39] <PCW> to see warts goan awn
[15:30:38] <gonzo_> on the show, it lists nothing, other than the column headings
[15:31:13] <PCW> thats a bit... weird
[15:31:33] <PCW> no complaints from the loadrt hm2_7i90?
[15:32:50] <bz> i 3d printed my plate instead of milling it from sheet metal
[15:32:53] <bz> gg
[15:32:54] <gonzo_> nope, no errors from halrun
[15:33:12] <gonzo_> could it be a bad bitfile?
[15:33:35] <gonzo_> (Using 7i90_epp_svst4_8_ado)
[15:35:25] <Erant> PCW: I ordered three weeks ago, what's my chances?
[15:42:27] <Tom_itx> gonzo_, did you make the bitfile?
[15:43:14] <PCW> gonzo_ just tried with linuxcnc 2.7.1, works as expected
[15:43:16] <PCW> 7i90.ini file is only different from 7i43.ini in 3 ways:
[15:43:17] <PCW> card=7i90
[15:43:19] <PCW> driver=hm2_7i90
[15:43:21] <PCW> config line has firmware token removed
[15:44:00] <PCW> loads and runs
[15:44:01] <PCW> a bitfile problem would most likely spew a bunch of errors
[15:44:23] <PCW> Erant: what order number?
[15:44:29] <Tom_itx> well i compiled one with the wrong size chip once
[15:44:57] <Tom_itx> that's why i asked if he generated the bitfile
[15:46:28] <gonzo_> PCW, that looks like what I have in the ini file.
[15:46:41] <gonzo_> the bit file is one that came with the 2.7.1 install
[15:46:48] <PCW> what linuxcnc version do you have?
[15:48:16] <PCW> OK 2,7.1 just worked for me, not sure if the 7i90 config was part of 2.7.1 or not but it launched OK
[15:49:06] <gonzo_> what bitfile do you suggest I try?
[15:49:08] <PCW> (its the hm2_servo demo)
[15:49:53] <PCW> I dont suggest you mess with bitfiles at all, if you dont have the read function thats unrelated
[15:53:09] <gonzo_> ok, tried the hm2_servo demo/example config
[15:53:57] <PCW> heres the beginning of the 7i90.ini file for hm2_servo:
[15:53:58] <PCW> [HOSTMOT2]
[15:54:00] <PCW> DRIVER=hm2_7i90
[15:54:02] <PCW> BOARD=7i90
[15:54:02] <PCW> CONFIG="num_encoders=3 num_pwmgens=3 num_stepgens=0"
[15:54:32] <gonzo_> I get mh2-servo.hal:45: parameter or pin 'hm2_7i90.pwmgen.pwm_frequency' not found 6663
[15:54:33] <PCW> that's all the 7I90 specific changes
[15:55:33] <gonzo_> ah, let me add thiose
[15:57:18] <gonzo_> ah, I think I was missing the CONFIG
[15:57:41] <gonzo_> though that was only needed for the boards where you upload the firmware
[15:57:47] <gonzo_> at load time
[15:59:47] <gonzo_> PCW, thanks a lot for the help
[17:01:55] <andypugh> It semi-painful to admit it, but having found that Fusion 360 CAM is free for non-profits (like me) and runs native on my Mac, I am rather liking it.
[17:07:12] <Deejay> gn8
[17:10:14] <andypugh> I am a little iffy on the Cloudiness of it.
[17:10:41] <malcom2073_> I'm hoping eventually onshape will do CAM
[17:11:32] <malcom2073_> Woohoo, my dad is bringing me a v-carve cutter tomorow morning, should be able to start engraving stuff.... *really really* slowly tomorrow
[17:11:51] <malcom2073_> Couldn't convince him to loan me his speeod heh, so I'm limited to 3krpm
[17:12:18] <andypugh> I am hoping that FreeCAD will get there, but at the moment, with parts to make now, and with full 3D adaptive HSM toolpaths, 360 is hard to beat. I might even have paid their $25 a moth,
[17:13:07] <andypugh> 3k rpm? Luxury! I have 1200 rpm (and that’s by over-driving the motor through the VFD)
[17:14:05] <malcom2073_> I have a varidrive or whatever it's called
[17:14:15] <malcom2073_> so I get a decent amount of speed out of it, I could probably overdrive the motor too since I'm not loading it hard
[17:14:16] <andypugh> I should just get a cheap chinese spindle to bolt on the face of the overarm. It wouldn’t even be difficult.
[17:14:22] <malcom2073_> unsure how the spindle bearings would handle it
[17:14:37] <malcom2073_> My dad wanted to bolt a router to his quill at one point
[17:14:40] <malcom2073_> till he found a cheap speedo
[17:14:58] <andypugh> They made my spindle in a 2500 rpm version, it is just that my particular machine got both slow ratios
[17:15:33] <andypugh> I am thinking of making a speeder, I have a design in mind, but actually a high speed spindle would be easier and cheapr
[17:15:54] <malcom2073_> Yeah, unless you come across one at an auction cheap, china spindles are pretty easy
[17:24:59] <Sync> andypugh: yeah freecad breaks my workflow completely
[17:26:15] <andypugh> I also have a legitimate Autodesk Inventor license, and used to use Inventor as a full-time job, so I can design without thinking much about the tools now.
[17:27:19] <bz> i use scad
[17:41:32] <wolfmanjm> I use scad but it doesn't generate real circles or arcs and things like cambam require that to work properly
[17:43:03] <JT-Shop> 2d or 3d?
[17:43:57] <JT-Shop> http://gnipsel.com/images/shop/Siding04.jpg
[17:44:05] <JT-Shop> http://gnipsel.com/images/shop/Siding05.jpg
[17:44:13] <JT-Shop> much less siding on the garage floor
[17:50:29] <andypugh> That’s not “siding” that’s “ending”
[17:51:37] <andypugh> If you built you sheds by piling rocks on top of each other like civilised folk do you wouldn’t need to do this sort of thing more than once a century or so.
[17:52:12] <JT-Shop> at my age I won't care when it falls down lol
[17:52:45] <JT-Shop> crap I can't upload, I'm in data restriction
[18:10:05] <Tom_itx> The image ".....siding04.jpg" cannot be displayed because it contains errors.
[18:10:34] <Tom_itx> 404 on the other one
[18:10:51] <JT-Shop> yea, <JT-Shop> crap I can't upload, I'm in data restriction
[18:11:06] <Tom_itx> mmm
[18:11:23] <JT-Shop> I need uSend to go with uGet
[18:11:24] <JT-Shop> lol
[18:13:35] <Erant> PCW: Sorry, had to run. 1607
[18:14:23] <Tom_itx> Lunch S,S
[18:14:23] <Tom_itx> Nothing cause Im not hungry
[18:14:27] <Tom_itx> wtf
[18:16:02] <JT-Shop> check your BP
[18:17:10] <Tom_itx> it's not too bad right now
[18:17:30] <Tom_itx> i checked when i first went to the doc for my neck and it was 140/110
[18:18:21] <Tom_itx> been pretty much sticking to that dash diet
[18:20:16] <JT-Shop> I've been sticking to JT's dietary plan
[18:21:08] <JT-Shop> so far I've lost 44 lbs
[18:47:39] <JT-Shop> dammit I'm down to one error
[19:01:41] <andypugh> This is jolly clever. https://www.youtube.com/watch?v=1AduH8lmucA (ffwd to 2.00min to get to the nub of it)
[19:13:03] <PetefromTn_> jeez if only I could afford itLOL
[19:13:58] <andypugh> You probably could afford it. Just not it and food :-)
[19:15:05] <PetefromTn_> heh probably
[19:15:09] <PetefromTn_> I do have good news tho
[19:15:38] <PetefromTn_> I think I just finalized the deal with DMM for my CNC lathe Servos and drives
[19:15:53] <andypugh> Which drives?
[19:16:05] <PetefromTn_> I got the DYN4
[19:16:14] <PetefromTn_> 750watt AC servos
[19:16:35] <andypugh> Good, the DYN2 has a nasty feature, full speed if the analogue input is disconnected.
[19:16:54] <PetefromTn_> any information on the DYN4's
[19:17:38] <andypugh> Not really. At one point DMM asked if i could “LinuxCNC certify” them, but I had to admit we had no such process.
[19:17:39] <PetefromTn_> I have heard good things on them on the zone
[19:18:00] <PetefromTn_> they made me what I consider a great deal
[19:18:21] <PetefromTn_> I am just afraid of the customs fees they will impose when I receive them
[19:19:02] <PetefromTn_> I got the complete package with drives, motors, cables for power and encoders, tuning cable, software etc.
[19:19:27] <andypugh> Is it worth hopping over the border to collect them?
[19:20:06] <PetefromTn_> hehe no I doubt it
[19:20:19] <PetefromTn_> its SUPPOSED to be less than 10percent
[19:20:41] <PetefromTn_> so that should be less than a hundred bucks but they said they cannot detemine exactly
[19:21:32] <andypugh> You might be able to guess by pretending to buy something from eBay from CA
[19:21:42] <andypugh> Sorry, I meant .ca
[19:22:08] <PetefromTn_> as long as it does not go over a hundred I willl be fine with it.
[19:22:42] <PetefromTn_> either way it is WAY less than I would have been paying for anything reasonably this nice that I have found so far.
[19:34:18] <PetefromTn_> well its paid for and we will see how long it takes to get here and how much the customs fees turn out to be
[19:38:13] <Tom_itx> do a couple quick jobs while you're waiting and you'll surely have it covered
[19:43:36] <PetefromTn_> Tom_itx actually I have a BUNCH of work for the shop to do coming up here next week that will be probably enough to pay for the whole retrofit hopefully
[19:44:19] <PetefromTn_> now I gotta decide on the best VFD to get
[19:48:03] <SpeedEvil> :)
[19:52:52] <Tom_itx> next thing you can invest in some good cad cam
[19:53:33] <PetefromTn_> yeah I know right.
[19:53:50] <PetefromTn_> I can't see anything more than fusion 360 tho
[19:55:09] <Tom_itx> i've never used it but it might be adequate for your needs
[19:55:35] <PetefromTn_> honestly what I have is ADEQUATE for my needs I seldom do anything really complex or 3D so far
[19:55:51] <Tom_itx> that's where the money's at
[19:56:06] <PetefromTn_> thats what they tell me but so far that has not happened
[19:56:18] <Tom_itx> my bud started out like you
[19:56:32] <Tom_itx> doing odd jobs for 3rd party or small companies
[19:57:04] <Tom_itx> worked up to doing experimental parts for aircraft and finally into the production side
[19:57:26] <Tom_itx> getting bids on more complex parts each step of the way
[19:57:37] <Tom_itx> and learning how to bid them
[19:58:29] <Tom_itx> he started with a manual mill, bridgeport and a bridgeport tracer
[19:58:51] <Tom_itx> err manual lathe..
[19:59:08] <Tom_itx> still owns all but the tracer
[20:01:21] <PetefromTn_> yeah I don't honestly see me ever getting terribly big or moving into a huge shop or anything like that
[20:01:53] <PetefromTn_> I just want to have the CNC lathe and the CNC mill completed and working to the point that I can make parts/money with them and be able to repair them if they go down
[20:02:29] <PetefromTn_> if the business continues or improves from where it is now I will be pretty pleased with this. anything more than that would be a blessing to be sure
[20:02:48] <Tom_itx> it will
[20:02:50] <PetefromTn_> I really LOVE working for myself and working mostly from my home with my kids/family around me here
[20:03:35] <PetefromTn_> when I get a nice paying job and stuff some cash into savings it gives me a big huge smile and makes me feel that all this work and learning was worth the trip.
[20:04:19] <PetefromTn_> I wish I could fit/afford a nice CNC slantbed like Zeeshan got but honestly just having a nice CNC lathe with some sort of toolchanger will go a LONG way to allowing me to do some cool stuff.
[20:04:52] <PetefromTn_> Eventually if I outgrow it I will probably move it aside in the shop and get something bigger
[20:05:25] <PetefromTn_> It is looking that the Hitachi WJ200 is going to be the choice for the VFD drive as there are no other reasonably priced options out there.
[20:05:42] <PetefromTn_> I have had relatively good success from the one in the cincinatti so far
[20:06:09] <PetefromTn_> I may use my paycheck from work tomorrow to buy it and get it also on its way here
[20:06:37] <PetefromTn_> Trying to stuff some cash away for Christmas and the holidays too so gotta choose wisely ;)
[20:07:46] <PetefromTn_> https://knoxville.craigslist.org/tls/5289168617.html looks like a great deal
[20:10:51] <robinsz> evening ...
[20:11:20] <PetefromTn_> evening
[20:11:37] <robinsz> for your amusement https://www.dropbox.com/s/713t5fpgxvuvbdf/IR_0104.jpg?dl=0
[20:12:00] <robinsz> https://www.dropbox.com/s/tp4r3614nvj0vus/IR_0106.jpg?dl=0
[20:12:17] <robinsz> after 3.5 hours at 18k rpm
[20:13:00] <PetefromTn_> gettin warm there man
[20:13:55] <robinsz> 70c inside spindle housing is OK i think
[20:14:30] <andypugh> 75C inside the spindle? That seems rather warm. Mine gets pretty hot at 1000 rpm, though. I probably should check the preload.
[20:15:07] <andypugh> I doubt it is hot enough to damage anything except your fingers.
[20:15:09] <robinsz> at 4k it stays cool to the touch
[20:15:53] <robinsz> its probably using regular moly grease instead of high speed stuff that does it
[20:16:56] <robinsz> im very impressed with the perfrormance of the cutter though
[20:17:06] <robinsz> Onsrud single flute
[20:17:25] <andypugh> Woodwind solo?
[20:17:37] <robinsz> each sheet takes about 3.5 hours at 18k rpm
[20:17:49] <robinsz> haha
[20:18:03] <robinsz> 3 sheets on this cutter now, still going well
[20:18:09] <PetefromTn_> whatcha makin?
[20:18:24] <robinsz> 19in rack mount panels
[20:18:34] <robinsz> 60 to a sheet
[20:19:41] <PetefromTn_> no idea what that is
[20:20:13] <robinsz> 19 inch rack units?
[20:20:30] <robinsz> standard electronics industry size for equipment

[20:22:18] <robinsz> the trajectory planner in 2.7.x is *perfect*
[20:22:45] <robinsz> im running helical ramps into the small pockets and it is smooooooooooooooooooooth
[20:27:01] <robinsz> not quite managed to get my xhc-hbo4 pendant to work right though :(
[20:27:39] <PetefromTn_> Oh cool you got one of those
[20:27:45] <PetefromTn_> I like the looks of the wired one
[20:27:53] <robinsz> i went wireless
[20:28:04] <robinsz> its fine on the sim
[20:28:20] <robinsz> just not managed to get the righ tmagic to make it work on my real one
[20:28:21] <PetefromTn_> I am sure it is probably fine but I am a wired kinda guy
[20:29:13] <robinsz> yeah, no batteries to go flat
[20:31:06] <robinsz> the new Vectric cut 2d pro is VERY good as well
[20:31:23] <robinsz> for routing, I recommend highly
[20:32:15] <robinsz> I need a good cam package for some hobby parts though, 3d milling
[20:33:05] <andypugh> http://www.picpaste.com/pics/Screen_Shot_2015-10-29_at_22.20.44-RtdPS7Sb.1446167329.png
[20:34:10] <PetefromTn_> damn thats pretty pro looking
[20:34:40] <andypugh> Well, it’s identical (just about) to HSM Pro bit £7500 less :-)
[20:35:34] <andypugh> robinsz: If you can stand Windows / Mac and being Cloud based, Fusion 360 is free if your company makes less than 100k a year. (or for hobby use)
[20:35:37] <Tom_itx> andypugh, what formats will fusion 360 import?
[20:35:56] <Tom_itx> and it comes with cam?
[20:36:10] <Tom_itx> not a bad deal for a small outfit really..
[20:36:47] <robinsz> andypugh, that looks decent
[20:37:00] <andypugh> It’s wierd, you have to upload the model to the cloud to convert some things (including Inventor .ipt). Local import is Iges, SAT, STEP And f3d
[20:37:22] <Tom_itx> sat and iges are pretty common
[20:38:44] <Tom_itx> how do you specify the material size when putting tools to the model?
[20:38:48] <andypugh> This is the upload-convert list: http://www.picpaste.com/Screen_Shot_2015-10-30_at_01.13.57-qw9DWTfO.png
[20:38:57] <robinsz> iges is fine
[20:39:12] <Tom_itx> yeah i can do just about anything i need with iges
[20:39:22] <robinsz> I tried Mecsoft FreeMill
[20:39:34] <robinsz> that was a waste of electrons ... totally useless
[20:40:11] <robinsz> it will do 1 pass, full depth. no part depth passes
[20:40:25] <robinsz> and either raster X or raster Y
[20:40:26] <andypugh> Tom_itx: ANy way you want, by default it makes a cuboid that you can adjust the size of, but you can choose a cylinder or a tube, and if you need to you can also model a solid and use that.
[20:40:31] <robinsz> no profile passes ...
[20:41:32] <andypugh> As far as I can see Fusion 360 has every feature of the Inventor HSM Pro package, which seems crazy :-)
[20:42:16] <robinsz> Im assuming this is their attemot to get back into the Solidowrks community
[20:42:18] <PetefromTn_> I need to try it
[20:42:51] <Tom_itx> andypugh, that's handy
[20:43:08] <robinsz> props to Da Pugh for the info, looks neat
[20:43:11] <Tom_itx> you might inspire me to look at it
[20:43:49] <andypugh> it also does “rest machining” ie, it wil carry on where the previous op left off. And it is rather good at staying down and steering round unmachined bits, which saves a lot of time.
[20:44:37] <robinsz> right
[20:45:21] <andypugh> Interesting example of adaptive clearing: https://picasaweb.google.com/lh/photo/Lp4Jt1r6QCY7dqxID6Tq4dMTjNZETYmyPJy0liipFm0?feat=directlink
[20:45:36] <robinsz> once upon a time ... I had a dodgy copy of Visual Mill that did a lot of that nice stuff, but I think it disappeared in some random computer death event about 10 years ago
[20:46:16] <andypugh> That was a square lump. It machined it at 10mm step-down, then backs up in 1mm steps to correct the profile, all as part of the same strategy.
[20:47:03] <andypugh> A bull-nose cutter would have been ideal, but I don’t have any.
[20:47:27] <Tom_itx> you can grind some :)
[20:47:59] <robinsz> nice
[20:48:09] <robinsz> pattern for a casting I take it?
[20:48:21] <Tom_itx> how did it handle the pocket cutouts?
[20:48:37] <Tom_itx> did it remember where it had cut on the cone?
[20:49:29] <andypugh> robinsz: Yes, it’s a replacement for the compound slide on the lathe. No point having a floppy compound on a CNC
[20:49:49] <robinsz> and the other huge patterny things?
[20:49:54] <robinsz> same project?
[20:50:21] <andypugh> Tom_itx: Yes. It basically does exactly what you would expect to do if you were making it by hand and had miraculous hand-eye coordination.
[20:50:53] <Tom_itx> what did you have to do to the post to get it right for lcnc?
[20:51:06] <andypugh> robinsz: Yes, the big white thing is the thread cutting gearbox replacement (1kw servo mount + ballscrew bearings) and the other other one is the cover for the X axis drive.
[20:51:22] <andypugh> There is a built-in Linuxcnc post (called emc)
[20:51:33] <Tom_itx> cool
[20:51:49] <Tom_itx> will it do lathe as well?
[20:51:59] <andypugh> I have told them to change it to LinuxCNC a few times, but they don’t seem to listen)
[20:52:10] <Tom_itx> not really sure you need a lathe cad cam honestly
[20:52:27] <andypugh> Tom_itx: Yes, you can see it in the ribbon on the first screenshot. (click the picpaste page for full size)
[20:52:28] <robinsz> nice
[20:53:06] <robinsz> I played an a mates manual-cnc Harrison
[20:53:30] <robinsz> you could basically teach it on the handwheels, stick another bit of metal in, press replay, done.
[20:53:50] <andypugh> That’s cool.
[20:54:01] <robinsz> very
[20:54:12] <andypugh> I don’t know it it is actualy useful, but it is cool :-)
[20:54:44] <andypugh> Anyhow, I ought to be in bed.
[20:54:54] <robinsz> yes
[20:55:00] <andypugh> I think that the same might be true of ye?
[20:55:05] <Tom_itx> later andy
[20:55:11] <andypugh> Goodnight.
[20:55:24] <robinsz> nah, im in vampire mode :)
[21:03:47] <jdh> my HD died on my mill. Hope I saved the config somewhere
[21:04:39] <Tom_itx> you better have
[21:08:18] <PetefromTn_> Cool
[21:08:45] <PetefromTn_> just received a sweet picture from an international customer of my Feinwerkbau P800 rail on his rifle
[21:09:04] <PetefromTn_> http://imgur.com/MfnkmnE
[21:09:37] <jdh> I have one from 2012
[21:10:01] <jdh> pete: looks pretty sexy. Have you anodized any of them?
[21:10:05] <Tom_itx> one thing good about a webserver.. i keep a copy up there
[21:11:00] <PetefromTn_> yeah I have anodized quite a few but that one was not obviously he just wanted it silver
[21:11:32] <jdh> I have plenty of places I could have saved copies, I just seem to have not done so in several years.
[21:12:00] <Tom_itx> well if you haven't changed it in years you're good
[21:12:20] <Tom_itx> once it works.. no reason to
[21:13:01] <jdh> I could take the opportunity to upgrade and swap my 7i43 for something less p-porty.
[21:13:20] <Tom_itx> i fried mine and went with the 7i90
[21:13:22] <Tom_itx> i like it
[21:14:24] <Tom_itx> unless you wanna go pci pcie
[21:14:33] <jdh> works with 7i47/etc?
[21:14:42] <ssi> anything 50pin
[21:14:43] <Tom_itx> i'm using a 7i47 on mine yes
[21:14:51] <jdh> I have a 7i47 and 7i39ta in there
[21:14:57] <Tom_itx> should be fine
[21:15:07] <Tom_itx> 39 is a breakout isn't it?
[21:15:11] <jdh> yeah
[21:15:16] <Tom_itx> np then
[21:15:30] <Tom_itx> cheaper and you get an extra port
[21:15:32] <jdh> anything better about it than 7i43? different?
[21:15:35] <Tom_itx> 72 io
[21:15:43] <Tom_itx> cheaper and more io :D
[21:15:59] <ssi> newer design, uses cheaper better fpgas
[21:15:59] <PetefromTn_> I'm likin my 5i25/7i77 ;)
[21:16:09] <Tom_itx> and you load the bitfile to the card
[21:16:21] <Tom_itx> so you don't need to specify it in the ini
[21:16:30] <Tom_itx> you do still need the CONFIG line
[21:17:43] <Tom_itx> i'd suspect the 7i43 to be phased out but i'm just guessing
[21:18:22] <jdh> anyone have a pointer to a decent sized cheap ssd ?
[21:18:39] <ssi> http://amazon.com
[21:18:47] <jdh> are they all teh same?
[21:18:56] <ssi> what's your goal
[21:19:03] <Tom_itx> i've got a tiny 32g for testing
[21:19:12] <ssi> for sticking in a linuxcnc machine, cheaper the better
[21:19:16] <Tom_itx> no they're not all the same
[21:19:16] <jdh> yeah
[21:19:22] <ssi> for your primary workstation, no they're not all the same
[21:20:08] <Tom_itx> some apparently die prematurely
[21:20:12] <jdh> just linuxcnc on an oldish atom
[21:20:27] <ssi> my recommendation:
[21:20:35] <ssi> cheap SSDs, even 16 or 32g is plenty
[21:20:42] <ssi> check your configs into a git repository
[21:20:48] <ssi> consider the machine disposable
[21:21:05] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/intel_atom/SSD2.jpg
[21:21:16] <Tom_itx> i got that long time ago just for testing stuff

[21:22:22] <jdh> wow... that is ugly.
[21:22:25] <ssi> :D
