[00:00:06] <andypugh> How about the 7i34?
[00:00:08] <PCW> (or PWM/DIR+encoder)
[00:00:50] <PCW> yeah but no terminal blocks (7I47 is another option)
[00:01:38] <andypugh> Or DB25 FPGA card and 7i85S?
[00:01:45] <PCW> Yes
[00:01:51] <Frank___2> got lost
[00:01:52] <Frank___2> hahaha
[00:02:00] <andypugh> (Do you think we have confused him enough yet?)
[00:02:12] <Frank___2> i am needing lots of i/o
[00:02:22] <Frank___2> each driver is gonna need 14 i/o
[00:02:28] <Frank___2> (4of them)
[00:02:32] <Frank___2> + limits etc
[00:02:40] <andypugh> Didn’t we decide that they were 7 differential pairs?
[00:03:08] <Frank___2> mmm i think thats for the step dir ones
[00:03:19] <Frank___2> and encoders
[00:03:32] <bpuk> out of curiousity - which drives are you using?
[00:04:21] <Frank___2> panasonic liqi 1kw IGBT PWM method sine wave drive
[00:04:22] <Frank___2> Differential input; (of input pulse train
[00:04:59] <Frank___2> i was going to go with 5i25+7i85s+ an expansion for field i/o
[00:06:41] <PCW> afk
[00:06:49] <Frank___2> its cool guys, first build and its hard to explain myself, i am going to keep re reading and figure it out :-)
[00:06:56] <andypugh> So: what paint that I can buy on a Sunday, in the UK, is suitable for painting the inside of an oil tank / gearbox?
[00:09:43] <bpuk> it's that 'sunday after new year' that's the killer - I'd go with Glyptal for the paint. But where to find it on a sunday...
[00:10:05] <Frank___2> doesnt oil do the trick?

[00:11:56] teepee_ is now known as teepee
[00:12:02] <andypugh> They always paint the inside of gearboxes.
[00:12:02] <bpuk> andypugh: don't suppose you've done any epoxy granite? epoxy resin is likely to do the job
[00:12:29] <bpuk> failing that, do you know anyone who is more fanatical than you about restoring bikes?
[00:13:33] <bpuk> Rustoleum primer may also be ok - but I'm... less confident on that one.

[00:17:39] <Frank___2> you should borrow one from a closed store, if you know what i mean.. hahaha
[00:18:44] <bpuk> problem is, the only store I can think of that might stock it is frost's - and there... a bit of a distance from andy :P
[00:20:21] <andypugh> B&Q do Rustoleum, but not, it seems, anything “serious”: If I search for exterior metal paint and Rustoeoum I find: http://www.diy.com/departments/rust-oleum-american-accents-gold-effect-metallic-effect-leafing-pen-93ml-pen/128297_BQ.prd
[00:21:29] <bpuk> http://www.diy.com/departments/rust-oleum-white-matt-primer-400ml-aerosol/81430_BQ.prd
[00:22:34] <andypugh> I want something I can brush on, really.
[00:22:49] <bpuk> http://www.diy.com/departments/rust-oleum-dark-grey-matt-magnetic-primer-500ml/81440_BQ.prd
[00:23:06] <bpuk> just checking the oil compatibility on the second one now
[00:23:28] <andypugh> I am not sure I want to use Magnetic paint on a lathe….
[00:23:35] <bpuk> heh
[00:23:41] <bpuk> would take any shavings out :P
[00:25:39] <andypugh> I might try this: http://www.diy.com/departments/fortress-grey-matt-anti-rust-primer-250ml/80942_BQ.prd?icamp=recs
[00:26:53] <bpuk> solvent based primer... do they do it in red oxide?
[00:27:58] <andypugh> The original gearbox was painted in a pink paint internally. Probably actual red lead.
[00:31:34] <bpuk> probably - I've always tended to use red oxides for oil exposed surfaces - the grey one looks good though
[00:31:51] <bpuk> guess there is only one way to find out though :D
[00:32:04] -!- rob_h has quit [Ping timeout: 250 seconds]
[00:32:54] <andypugh> My worry is that if is peels off it will block the oil pump that feeds the lathe headstock. Which is probably bad.
[00:33:46] <bpuk> hence the Glyptal suggestion - but I have no idea where you'd get it on a sunday
[00:34:03] <Roguish> andypugh: do you really need to paint it?
[00:34:37] <bpuk> it's a raw, unblasted casting - unless he has a filter on the oil pump, then yes
[00:34:52] -!- asdfasd has quit [Ping timeout: 272 seconds]
[00:35:00] <andypugh> My dad once told be you should. And he used to work for a gearbox manufacturer. And he always painted the insides of gearboxes he made.
[00:36:20] <andypugh> And something has to need painting pretty badly for my dad to bother :-)
[00:38:15] gentoognuhurd is now known as justanotheruser
[00:41:13] <bpuk> there are 2 usual reasons to paint castings - the first is to stop oil weeping through the pores in the casting. the second is to to encapsulate any stray casting sand - I've also been told that it 'helps the oil return better' - but I take that with a pound of salt
[00:42:23] <andypugh> It will also prevent rust.
[00:43:35] <bpuk> depends how often you're letting the machine stand - in a frequently running machine rust inside the gearbox isn't really a concern - the moving oil mostly stops any air getting to the iron
[00:43:47] <bpuk> but yeah, that's a bonus
[00:48:58] <bpuk> I think my googlefu is failing me - I've got a Granite Devices Argon coming soon. I'm trying to figure out if anyone has worked on getting thier 'simplemotion' interface working under linuxcnc
[00:49:24] <bpuk> electrically it's RS485 - which shouldn't be an issue

[03:18:50] <os1r1s> 123dapp sucks

[03:20:48] <zeeshan> only 21 k.
[03:20:49] <zeeshan> :{
[03:21:15] <zeeshan> i wonder how hard it'd be to build that
[03:21:23] <zeeshan> its basically a 6 axis encoder
[03:21:25] <zeeshan> :)
[03:21:51] <os1r1s> Looks nice
[03:21:53] <os1r1s> But pricey
[03:22:01] <zeeshan> i used that at a job
[03:22:05] <zeeshan> for reverse engineering molds
[03:22:22] <os1r1s> IM molds?
[03:22:29] <zeeshan> plastic injection molds
[03:22:39] <os1r1s> zeeshan Did you design IM molds?
[03:22:52] <zeeshan> whats IM
[03:23:06] <os1r1s> injection molding
[03:23:10] <zeeshan> oh
[03:23:11] -!- Duc has quit [Ping timeout: 276 seconds]
[03:23:12] <zeeshan> yes
[03:23:19] <os1r1s> In solidworks?
[03:23:23] <zeeshan> yes
[03:23:29] <zeeshan> we were making preforms
[03:23:30] <os1r1s> And mill them/
[03:23:45] <zeeshan> the things that you blow mold into a bottle
[03:23:55] <zeeshan> i just did the solidworks
[03:23:59] <zeeshan> the guys on the floor did the machining
[03:24:08] <enleth> zeeshan: any experience with metal casting molds?
[03:24:16] <os1r1s> zeeshan I have two small IM machines
[03:24:16] <Tom_itx> zeeshan's Back!!
[03:24:30] <os1r1s> And have had limited success injecting. So advice/input is always nice
[03:24:36] <os1r1s> These weren't blow molds though
[03:24:37] <zeeshan> os1r1s: what type of injection molding
[03:24:40] <zeeshan> like a screw extruder
[03:24:44] <zeeshan> between a press?
[03:24:47] <os1r1s> Yes
[03:24:48] <zeeshan> nice!
[03:25:01] <os1r1s> One is a medium machinery one. The other is a techkits lns-150a
[03:25:05] <zeeshan> enleth: my first metal mold just happened a couple weeks ago :)

[03:26:20] <rue_shop3> ah you
[03:26:22] <zeeshan> are you a master catia
[03:26:30] <rue_shop3> looking for a list of grbl commands
[03:26:32] <Tom_itx> beginner
[03:26:46] <rue_shop3> heh
[03:27:00] <rue_shop3> hey I wrote my own stuff from scratch and I can do it again
[03:27:05] <rue_shop3> just dont want to :)
[03:27:24] <enleth> zeeshan: nice. looks like the same kind of process I'm aiming for, but it's in the backburner now
[03:27:48] <enleth> just gathered all the stuff needed to make a furnace but no time to build it
[03:28:01] <zeeshan> if youre planning to do aluminum only
[03:28:05] <zeeshan> a kiln is cheaper :P
[03:28:16] <enleth> not necessarily
[03:28:18] -!- floppydiskph [floppydiskph!~floppydis@172.56.38.163] has joined #linuxcnc
[03:28:35] <enleth> also, I do not trust gas-fired stuff
[03:28:46] <zeeshan> electric kiln
[03:29:00] <zeeshan> i got mine for $100
[03:29:16] <zeeshan> works good for heat treating also
[03:29:34] <zeeshan> cant melt brass or copper or steel :(
[03:29:40] <Tom_itx> rue_shop3, maybe: http://www.aquickcnc.com/wiki/Grbl
[03:30:37] <Tom_itx> zeeshan just add oxy
[03:30:38] <rue_shop3> Grbl is a no-compromise, high performance....
[03:30:44] <rue_shop3> I'm laughing now...
[03:30:50] <os1r1s> zeeshan I hooked my electric kiln up to a PID cntroller
[03:30:55] <os1r1s> zeeshan So I can do heat profiles
[03:30:57] <zeeshan> os1r1s: same
[03:31:04] <zeeshan> theyre pretty useless without one
[03:31:07] <Tom_itx> rue_shop3 so use linuxcnc
[03:31:07] <zeeshan> for heat treatment
[03:31:31] <zeeshan> os1r1s: ive heard that some can handle 1400C
[03:31:33] <rue_shop3> Tom_itx, that dosn't matter much, but I dont have your $$$ of hardware to run the motors
[03:31:41] <Tom_itx> parport
[03:31:45] <zeeshan> that would be sweet
[03:32:06] <enleth> zeeshan: I'm aiming for pure brick and ceramics interior to try melting whatever ends up melting ad 1500C or so
[03:32:10] <Tom_itx> you could even run dual parport
[03:32:12] <os1r1s> zeeshan Mine can do 1300C
[03:32:14] <rue_shop3> what I want is a set of Gcodes that are understood so I can think about writing some cadcam to work with it
[03:32:20] <zeeshan> so you can melt brass easily then
[03:32:22] <os1r1s> I don't *think* it can do 1400C
[03:32:30] <rue_shop3> cause no way in hell I'm forking out for a windows system just to run cadcam
[03:32:31] <Tom_itx> did you see teh list of supported gcode in that link?
[03:32:37] <rue_shop3> no..
[03:32:49] <Tom_itx> you didn't scroll then

[03:33:38] <zeeshan> os1r1s: have you tried melting brass?
[03:33:44] <zeeshan> or copper
[03:33:54] <rue_shop3> I have a small electric kiln that will do brass
[03:34:54] <Tom_itx> zeeshan what's the sw model for?
[03:35:07] <zeeshan> its part of a sculpture
[03:35:18] <Tom_itx> making more polished turds?
[03:35:30] <zeeshan> http://i.imgur.com/yValqti.jpg
[03:35:31] <zeeshan> this thing
[03:35:52] <Tom_itx> what is it?
[03:35:58] <enleth> zeeshan: the heating elements I bought from a retired jewellery kiln serviceman can handle up to 1800C, I've got refactory that will survive continuous 1600C, the only interesting part is how to connect heating elements
[03:36:04] <zeeshan> some sculpture
[03:36:08] <zeeshan> im trying to cad it up
[03:36:12] <Tom_itx> oh
[03:36:15] <zeeshan> so i can make some of those wood pieces from metal
[03:36:19] <zeeshan> http://i.imgur.com/W8anhCh.png
[03:36:20] <zeeshan> :D
[03:36:47] <Tom_itx> gettin paid for it?
[03:36:47] <zeeshan> enleth nice
[03:36:50] <zeeshan> ofcourse!
[03:37:33] <zeeshan> im making more of those turds 3rd week of jan
[03:37:37] <zeeshan> he sold all of them lol
[03:37:45] <Tom_itx> really!?
[03:37:47] <zeeshan> yes!
[03:37:50] <zeeshan> 100 of them
[03:37:55] <zeeshan> all gone
[03:38:00] <Tom_itx> better charge more for the next batch
[03:38:05] <zeeshan> i am
[03:38:07] <zeeshan> hes okay with it
[03:38:14] <zeeshan> he's being fair cause he knows it takes time
[03:38:28] <Tom_itx> how much finish time did he put in to them?
[03:38:41] <zeeshan> i think each one takes him an hour
[03:38:48] <zeeshan> wiring it, and finishing it
[03:38:50] <enleth> the usual way to connect those heating elements for up to 1400C is with folded steel strips, looped onto themselves and bolted around the ends of elements
[03:39:28] <enleth> for higher temps - conductive ceramics
[03:40:03] <zeeshan> id like to melt steel
[03:40:05] <zeeshan> would be awesome
[03:40:21] <Tom_itx> and more dangerous
[03:40:26] <zeeshan> hehe
[03:40:53] <zeeshan> my gf was helping me pour some aluminum
[03:41:11] <zeeshan> she accidently spilled molten aluminum on the driveway
[03:41:17] <zeeshan> it popped :)
[03:41:37] <zeeshan> which caused her to panic and spill the entire thing on the driveway
[03:41:37] <zeeshan> haha
[03:42:02] <Tom_itx> you gotta be prepared for such things and not panic
[03:42:10] <zeeshan> yea
[03:42:14] <Tom_itx> nerves of steel
[03:42:35] <enleth> zeeshan: have you seen Grant Thompson's micro arc furnace?
[03:43:27] <enleth> The youtube "king of random", the guy usually makes silly projects, but with some of them he actually shows quite a bit of technical capacity
[03:43:38] <zeeshan> nope
[03:43:46] <t12> i blew up a cap last night
[03:43:50] <t12> it was very loud
[03:43:51] <enleth> zeeshan: https://www.youtube.com/watch?v=JIlZsuRc9jQ
[03:44:25] <enleth> surprisingly effective for small payloads
[03:45:34] <zeeshan> wow this guy
[03:45:36] <zeeshan> dumbass
[03:45:36] <zeeshan> hahaha
[03:45:41] <zeeshan> i thought i was dumb
[03:45:45] <Tom_itx> hahaha
[03:45:51] <zeeshan> he grabs his mold with his fucking bare hands
[03:45:56] <zeeshan> with molten aluminum
[03:46:10] <zeeshan> this arc furnace thing is cool
[03:46:21] <zeeshan> ive seen the local place melt massive scrap like that
[03:47:50] <Tom_itx> those are crappy molds
[03:47:56] <zeeshan> man
[03:47:59] <zeeshan> now i want to melt copper so bad!
[03:48:01] <zeeshan> that is bad ass
[03:48:05] <zeeshan> yea tom lol
[03:48:14] <enleth> but the concept is great
[03:48:31] <Tom_itx> how long do the carbon rods last?
[03:48:35] <enleth> he made some shit molds out of a porous material just to show how to do it *fast*
[03:49:13] <enleth> and the idea of a disposable crucible/kiln combo made out of a dirt cheap material is really nice
[03:51:52] <enleth> you can make a bunch of those in advance and possibly use more than one at at time for different materials to avoid contamination
[03:52:10] <os1r1s> zeeshan You see this? https://www.dropbox.com/s/el2qylfnnq97kha/anogrowth.jpg
[03:52:46] <enleth> os1r1s: what am I even looking at?
[03:52:51] <zeeshan> yes
[03:52:58] <Tom_itx> what is it?
[03:53:00] <os1r1s> enleth The growth in my ano tank from not using it in a year

[03:53:02] <zeeshan> :P
[03:53:15] <os1r1s> Tom_itx That is the anode or cathode (can't remember which)
[03:53:27] <os1r1s> And most of the water evaporated. That was some nasty stuff
[03:53:34] <enleth> ah, well, I'm getting that in the PCB etching tank
[03:54:00] <enleth> the difference is that it also eats away anything metallic some dumbass may have left inside
[03:54:01] <Tom_itx> my etchant crystalized it sat so long
[03:54:38] <os1r1s> haha
[03:55:56] <enleth> the tank sits upright on wooden supports and spills/splashes have etched away the wood so much that it looks like those 500 years old ship parts that turn up sometimes
[03:57:37] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/etching/newtank2.jpg
[03:57:40] <Tom_itx> i put a cover over mine
[03:57:53] <Tom_itx> set it in a tub when in use
[03:58:06] <Tom_itx> that was just a water test
[03:58:26] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/etching/etch3.jpg
[03:59:53] <enleth> Tom_itx: your photo reminds me that I have to buy a sheet metal shear for use with PCB
[03:59:58] <zeeshan> that looks cool tom
[04:00:27] <enleth> to get people to stop using power tools for cutting that crap

[04:00:57] <Tom_itx> i had probably 2 pickups full at one time
[04:01:23] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/etching/Copper3.jpg
[04:01:30] <Tom_itx> part of a full sheet i cut in half to store
[04:01:32] <enleth> one of the most difficult things in a shared workshop is explaining that a fibreglass composite is NOT something we want machined because the dust is abrasive and damages machines
[04:01:45] <Tom_itx> and lungs
[04:01:55] -!- bensbenz has quit [Remote host closed the connection]
[04:02:12] <enleth> screw their lungs, they will die anyway, while the machine could theoretically exist and operate forever
[04:02:36] <enleth> also, you can don a dust mask, but you can't put it on a mill
[04:02:48] <Tom_itx> the shop i got that from used a large shear to cut it
[04:03:08] <enleth> and that's the correct way to do it
[04:03:28] <Tom_itx> i used a tabletop paper cutter which worked ok
[04:03:34] <enleth> unless you need fancy shapes, then a milling plotter that is specifically protected against the PCB dust
[04:03:41] <enleth> and well vacuumed when cutting
[04:03:54] <Tom_itx> too hard on cutters
[04:04:37] <enleth> well shit, it's not like there's any other way
[04:04:44] <Tom_itx> yeah i know
[04:04:54] <enleth> you just buy cardbide cutters and live with the fact that they will wear out fast
[04:05:19] <enleth> well, you could die-stamp small PCBs
[04:05:25] <enleth> but that's obviously for big batches
[04:05:49] <Tom_itx> you don't get a nice edge though
[04:06:08] <enleth> otherwise just keep a separate box of endmills condemned to die a horrible death milling PCBs
[04:07:09] <enleth> the problem is, we don't have a separate milling plotter for PCBs and people keep trying to use the one that doesn't even have any screw covers
[04:07:26] <Tom_itx> i don't do many anymore
[04:07:37] <Tom_itx> if i had one i really wanted i'd let china make it for me
[04:08:02] <enleth> yeah, the prices for one-offs dropped a lot lately
[04:08:26] <enleth> 2-3 years ago it was a bit expensive to make a 1-5 piece run
[04:08:30] <Tom_itx> and you get a mask and the whole bit
[04:08:33] <enleth> now it's fine
[04:09:10] <Tom_itx> do you do your own smt soldering?
[04:13:30] <enleth> yes
[04:13:48] <Tom_itx> i made a toaster oven for doing batches
[04:14:05] <Tom_itx> did quite a few by hand before that
[04:14:08] <enleth> same thing, plus a couple of hot air stations
[04:14:22] <Tom_itx> i wish i had a hot air station
[04:14:57] <enleth> but a lot of guys actually use the soldering iron for smt work
[04:15:09] <Tom_itx> i did for quite a while
[04:15:19] <enleth> it's just as fast for low pin count parts
[04:15:28] <Tom_itx> 0603 was ok, 0402 i could do but not efficiently
[04:15:42] <Tom_itx> yeah chips are easy
[04:16:52] <enleth> as for hot air, for a long time all we had was an el cheapo chinese hotair I bought in high school
[04:16:55] <enleth> and it was fine
[04:17:19] <Tom_itx> i'd probably just use that for desoldering
[04:17:35] <enleth> it works, but a proper desoldering gun is better

[06:59:37] <Jymmm> renesis: Hey, duct tape or two part epoxy =)
[06:59:57] <renesis> omfg omg FUCK glued down parts
[07:00:06] <Jymmm> hahahahaha
[07:00:18] <renesis> how do we turn some simple rework into mad drama? glued parts
[07:00:43] <Jymmm> I get dumbass college students to do it for me =)
[07:01:02] <renesis> well big parts its fine
[07:01:23] <Jymmm> renesis: quit yer bitchn college boy ;)
[07:01:37] <renesis> SMD inductors are the worst, can get enough heat into them to break glue without basically melting half the board
[07:02:01] <Jymmm> Huh? What are you using?
[07:02:04] <renesis> man ive heard scary things about the grad student lab TAs
[07:02:32] <renesis> i only glue down big things for vibration issues and usually RTV or similar
[07:02:48] <renesis> i dont glue down small shit, china factories do
[07:02:50] <Jymmm> RTV?! you're kidding right? Hot glue gun
[07:02:52] <renesis> not always sure why
[07:03:26] <renesis> i use glue gun for a lot of stuff but pretty sure the typical white stuff everyone uses for vibration damping is an RTV
[07:03:59] <renesis> most hot glue is too rigid, would just break away and bang against the hot glue, need something rubber that sticks
[07:04:29] <renesis> i use masking tape to make little box molds to pot quick perfboard deadbug protos in hot glue, heh
[07:04:36] <Jymmm> That really depends on the type of hot glue, most common is soft, though I do have a few varieties
[07:05:13] <Jymmm> I even have GITD hot glue =)
[07:05:14] <renesis> its not the same, white stuff is a giggly RTV
[07:05:20] <renesis> yellow stuff is a hot glue
[07:05:47] <renesis> yellow stuff is more for strain relief, white stuff is like, damping on big parts and airtight sealing
[07:05:49] <Jymmm> That's the type used to seal pack boxes, wrong stuff
[07:06:02] <renesis> see it poured on the backs of connects, pretty nasty, do not approve
[07:06:20] <ReadError> glue as in wave soldering?
[07:06:25] <renesis> whats pack boxes
[07:06:54] <Jymmm> renesis: Used to seal corrigated cardboard boxes, like bottles of wine
[07:06:59] <renesis> readerror: i guess, i think its for double sided smd and heavy magnetic bits and sometimes they just carried away
[07:07:10] <renesis> when like 0805s are glued down im pretty wtf
[07:07:23] <renesis> jymmm: oh, yeah that stuff would work okay
[07:07:29] <ReadError> i thought in wave soldering everything is glued
[07:07:40] <Jymmm> renesis: that stuff is yelllow
[07:07:49] <renesis> for a lot of application, unvulcanized butyl rubber is used
[07:07:56] <renesis> bear shit, gorilla snot
[07:08:08] <renesis> bugenjaow
[07:08:14] <Jymmm> no not gorilla snot, that's gasket sealer
[07:08:28] <renesis> shrug, supposedly this is chinese that loosely translates to unvulcanized rubber
[07:08:43] <renesis> youre saying no, im telling you its industry standard
[07:09:00] <renesis> probably used in like every other subwoofer ever, heh
[07:09:15] <Jymmm> THIS is gorilla snot, damn fine gasket sealer http://contentinfo.autozone.com/znetcs/product-info/en/US/mmm/08581/image/3/
[07:09:33] <renesis> that probably sets and sticks
[07:09:44] <renesis> gorilla snot doesnt
[07:10:03] <Jymmm> doesn't set that fast, thus snot =)
[07:10:10] <renesis> its kind of like that blue poster stuff
[07:10:20] <Jymmm> poster putty?
[07:10:25] <renesis> unvulcanized rubber doesnt set ever
[07:10:28] <renesis> yeah
[07:10:38] <renesis> its like something between that and silly putty
[07:10:50] <Jymmm> Yeah, the 3m is gorilla snot, looks consistancy, but works great!
[07:10:55] <Jymmm> for what it is
[07:11:26] <Jymmm> great gasket sealer
[07:11:28] <renesis> well if you bring that to someone who asked for gorilla snot in the audio industry, theyre probably going to be sad
[07:11:48] <renesis> its used as acoustic damping a lot, too
[07:12:30] <renesis> its not a glue, it doesnt run, you wouldnt be able to squeeze it out of a tube
[07:12:50] <renesis> its basically black silly putty
[07:13:31] <renesis> like, comes in sheets and rolls
[07:13:42] <Jymmm> That would be for lows though
[07:14:11] <renesis> shrug, its just for sealing and damping vibration, so ya lows
[07:14:52] <renesis> HF vibrations that hurt things probably arent going to be consistent
[07:15:05] <Jymmm> define "HF" ?
[07:15:12] <renesis> typically shit goes nuts between 40 and like 200
[07:15:17] <Jymmm> < 50MHz ?
[07:15:29] <renesis> upper decade, so like above 2khz
[07:15:59] <Jymmm> THIS is what I use for lows http://www.lowes.com/pd_320879-73825-060-9507-46___?productId=3117463&pl=1&Ntt=recyceled+rubber+mat
[07:16:16] <renesis> if some shit is buzzing at 50mhz, i dont care no one will hear it, and deflection so tiny prob nothing dies
[07:16:40] <Jymmm> I thought you were talking RF
[07:16:46] <renesis> jymmm: prob similar density, its rubber
[07:17:16] <Jymmm> That isn't solid, it's ground pieces "adherde" together
[07:17:24] <renesis> but yeah how is that going to help me seal a speaker or stick a grill on without buzzes
[07:18:21] <Jymmm> what kind of speakers are you working on?

[07:22:27] <renesis> jymmm: ive done home/studio/live subwoofers at other places, half the job at least is troubleshooting rub and buzz issues
[07:22:56] <Jymmm> ah
[07:23:27] <renesis> have tested a lot of competitive product, pretty much everything buzzes somewhere, but its almost always between like 50 and 200

[07:24:00] <renesis> by 1khz, even if there is a buzz, the amplitudes are so small its not an issue
[07:24:16] <renesis> archivist: you can probably get recone kits
[07:24:48] <archivist> I got a silly quote from tannoy to re cone them
[07:24:50] <renesis> then its about careful shimming and steady glue hand
[07:24:56] <renesis> yeah they dont want to do that
[07:25:05] <renesis> like $500 each or something?
[07:25:17] <archivist> £300+ each
[07:25:40] <archivist> so yes about that price, was a long time ago I asked
[07:25:49] <renesis> yeah so like $450+
[07:26:04] <renesis> its reasonable in the sense that they probably have limited spares

[10:45:07] <rhaven> hi there, i just received a small desktop cnc machine, (my first :D). however, the old laptop i was going to use which has a parallel port has broken down. Instead of investing time/money to repair it, it seems a better choice to look into something more stable. Can anyone please share their experience with small motherboard pcs (mini itx?)
[10:45:49] <XXCoder> almost any pc 10 years or newer can do it
[10:45:57] <XXCoder> my 9 year old pc can do it
[10:46:22] <XXCoder> laptop, however, can't cut it for some reason. they all has bad lag
[10:46:35] <XXCoder> so it didn't matter that your laptop died, it would be unusable
[10:46:36] <archivist> older can be better, the new uefi can be a non starter
[10:46:48] <rhaven> XXCoder, better to buy an old pc?
[10:46:55] <XXCoder> arch knows more
[10:47:00] <trentster> Hey all, I was wondering would it be better to physically anchor a cnc router to a solid table vs leaving it resting on feet?
[10:47:12] <rhaven> the controller board is an SMC 800
[10:47:14] <XXCoder> trentster: actually I did wonder about that
[10:47:25] <XXCoder> heh i dont even have a solid table :P
[10:47:57] <trentster> heh - I bought a welded steel table, its pretty solid
[10:48:07] <XXCoder> nice
[10:48:11] <archivist> rhaven, if you trawl the logs PCW mentions an itx board which is ok
[10:48:41] <trentster> Yeah, it makes a big difference especially for rapid with acceleration
[10:49:33] <trentster> at the moment I dont have feet or have it anchored its supported by front and back alu flat bar so it rests on the machine itself

[15:33:25] <Magnifikus> anyone thought about car injection valves to inject coolant into an air stream for minimal coolant regulation? :D
[15:35:35] <malcom2073> Be significantly more complicated than a mister, for the same effect yeah? heh
[15:36:19] <Magnifikus> yeah ^^
[15:38:34] <archivist> a hard way of doing something simple
[15:39:56] <jdh> not that there is anything wrong with that.
[15:40:00] <SpeedEvil> injection valves are desinged for very low flow and high pressures
[15:40:10] <SpeedEvil> and uncontaminated non-corrosive (mostly) fuel
[15:40:53] <archivist> and the killer for carbide is intermittent cooling

[17:30:40] <PetefromTn_> there was a guy there with a .50 BMG
[17:30:57] <PetefromTn_> he was letting people try it out for like ten bucks a shot or something like that

[17:55:20] <zeeshan> i was thinking of outsourcing it

[18:04:23] <zeeshan> ive done thin stuff
[18:04:26] <zeeshan> like 16 gauge
[18:04:34] <PetefromTn_> depends on the airgun
[18:04:39] <zeeshan> im sure there is a company out there that can make me a 34" 1/4" ring
[18:04:48] <PetefromTn_> that steyr for instance the basic gun is like $3k or slightly less
[18:05:14] <PetefromTn_> the big bore airguns are not so expensive
[18:05:50] <PetefromTn_> if you have a decent lathe you can build them yourself they are not all that complex. Just a poppet valve, hammer and valve spring, a trigger and some O-rings LOL
[18:06:10] <PetefromTn_> Once my CNC lathe is running I plan to make some nice ones ;)
[18:08:10] <PetefromTn_> zeeshan how wide does the ring have to be?

[18:08:25] <zeeshan> oh
[18:08:29] <zeeshan> you mean in height
[18:08:30] <zeeshan> 7"
[18:08:34] <PetefromTn_> ah okay
[18:08:37] <zeeshan> pretty small
[18:08:55] <PetefromTn_> I was gonna suggest that you could use a tubing roller if it was like two or three inches wide

[18:09:27] <zeeshan> but i dont think itll handle 1/4"
[18:09:34] <zeeshan> and itll be a pain in the ass to make it round
[18:09:37] <zeeshan> cause its so wide

[20:08:15] <Jymmm> One fitting I had fit PERFECTLY fully seated with about 10 turns, the other two turns if that and stopped. So I guess one is tapered, and the other isn't

[20:29:56] <PetefromTn_> its pretty heavy duty too
[20:30:16] <PetefromTn_> I was planning to use it on the Cincinatti but it just did not make sense anywhere
[20:30:30] <enleth> PetefromTn_: even better, if you're creative, you can fit a keyboard under the monitor too
[20:30:41] <PetefromTn_> I will probably just tig weld up something nice for the machine

[20:40:11] <Duc> putting the end off

[20:48:52] <PetefromTn_> Soon tho :D
[20:49:50] <Duc> lol
[20:50:14] <Duc> so your going to issues step and dir to them?
[20:50:36] <Erant> I have a metalurgy question. Sort of. I'm replacing my Z screw with a ballscrew. The way it currently works is there's dovetails on the front and an arm that goes around to the back of the column and there's a screw there.
[20:50:53] <Erant> In order to do the ballscrew I have to replace that arm.
[20:50:54] <PetefromTn_> why hell no
[20:51:13] <zeeshan> pete why is step dir bad?
[20:51:16] <zeeshan> and why hell no
[20:51:16] <zeeshan> :P
[20:51:17] <PetefromTn_> this will be an analog controlled machine
[20:51:30] <PetefromTn_> I never said it was BAD ;)
[20:51:30] <Erant> Any tips on what I should make the arm out of? 6061 ok? Or should I go for steel?
[20:52:09] <zeeshan> Erant: pics = 1000 words
[20:52:10] <zeeshan> :)
[20:52:16] <Duc> PetefromTn_: Thought those drives took step and dir or can they be used in analog system also
[20:52:33] <zeeshan> ive been asking here why step dir is bad
[20:52:34] <PetefromTn_> I am pretty sure there are a couple different ways to control them
[20:52:42] <zeeshan> but no concrete answer
[20:52:48] <zeeshan> i think step dir the more i read about it is better
[20:52:51] <zeeshan> cause less noise issues w/ it
[20:53:13] <zeeshan> if your drives have the ability to control the velocity loop w/ amicrocontroller on the drive
[20:53:13] <PetefromTn_> great so use it on your new CNC lathe!
[20:53:15] <zeeshan> why not :P
[20:53:19] <zeeshan> im planning to
[20:53:32] <zeeshan> if the drives support it
[20:53:32] <Duc> with Step and dir there is no sure way to verify they actually made the steps
[20:53:41] <zeeshan> duc what?
[20:53:41] <Duc> my old stepper motors would lose steps
[20:53:46] <zeeshan> im talking about servos
[20:53:50] <zeeshan> w/ a feedback going into the drive directly
[20:53:56] <Duc> ah
[20:54:12] <Duc> Maybe less control over the adjustments
[20:54:14] <zeeshan> i really want to play with ethercat for the lathe
[20:54:22] <ReadError> zeeshan, still no answer on it?
[20:54:24] <zeeshan> thats true to some degree
[20:54:40] <zeeshan> but usually drive manufacturers have software to let you configure all your pid stuff
[20:54:46] <zeeshan> ReadError: nope :P
[20:54:50] <Duc> zeeshan: you could always find the ethercat module for the yaskawa drives for me
[20:55:04] <zeeshan> ReadError: i think people think of step/dir as steppers cause its mostly used for that
[20:55:10] <zeeshan> but a lot of fieldbus drives use step dir as well
[20:55:12] <zeeshan> for servo
[20:55:34] <ReadError> i enabled analog in the software and the settings looked hard so i scratched that

[21:33:33] <Tom_itx> zeeshan did you make a NY res to finish your lathe this year?
[21:33:52] <zeeshan> Tom_itx: it was on the list before the NY:P
[21:37:26] <bpuk> zeeshan: I've used both step/dir (well, CW/CCW) and analog on servos - neither one is 'better'. I tend to use step/dir where the drive is closing the position loop, and analog where the drive is closing the velocity or torque loop (but not position).
[21:38:14] <zeeshan> bpuk: wouldn't a digital signal be less susceptible to noise? making it better? :p
[21:39:02] <zeeshan> you can't close the position loop using step/dir?
[21:39:24] <zeeshan> (if the drive isn't closing the position loop)
[21:39:40] <bpuk> zeeshan: a serial signal with good ECC - sure, I've tuned, but not built, systems using that setup. step/dir I've not found to have noticably better noise resistance than analog
[21:40:48] <bpuk> you can close the position loop using step dir if your encoders are feeding back to the controller - but in that case, you're essentially feeding the drive a pwm signal - which often, gets smoothed out with an RC filter inside the drive, leaving a 0-10v analog signal anyway
[21:41:20] <bpuk> (that's if the drive is a velocity mode drive, being fed step-dir)
[21:41:22] <Erant> bpuk: I'm using STEP/DIR with my servos over CAT-5 with differential signalling. Seems to work fine.
[21:41:30] <Erant> Position control on the drive
[21:42:06] <bpuk> but would you use step/dir if you needed to control torque?
[21:42:52] <zeeshan> bpuk: see even though it becomes an analog signal back inside the drive
[21:43:11] <zeeshan> i like the fact that with a differential step/dir signal, you have some sort of error checking
[21:43:22] <zeeshan> to make sure the signal got communicated right
[21:43:27] <zeeshan> but w/ analog you don't have that ability
[21:43:56] <zeeshan> maybe this is why all the new machines come with some sort of fieldbus realtime driven drives
[21:44:22] <bpuk> can send a 0-10v differentially - balanced audio is the classic example
[21:44:31] <zeeshan> thats what im doign right now
[21:44:34] <zeeshan> i havent had noise issues
[21:44:57] <zeeshan> i guess the signal got transmitted wrong, the position loop at the controller would error out
[21:45:00] <zeeshan> cause it lost position
[21:45:00] <bpuk> fieldbus has other advantages - being able to configure the drive over the serial comms is really useful
[21:45:19] <zeeshan> bpuk: but you can remote into a computer and do the same? :)
[21:45:44] <zeeshan> im using modbus for my vfd to configure and read parameterrs

[21:46:28] <zeeshan> i do not want to give up position control to be left to the drive.

[21:50:41] <bpuk> ReadError: You're thinking machine tools - consider an extruder - torque control is often used to maintain a constant plastic pressure between the screw and the gear pump
[21:51:28] <zeeshan> torque control always handled within the drive right?
[21:51:43] <zeeshan> it has to be :P
[21:52:06] <bpuk> pretty much - you could handle torque control using say... DC servo's - where the drive is as dumb as can be
[21:53:33] <bpuk> So you're looking at the torque and velocity loops being closed by the drive, and linuxcnc closing the position loop? Serial, PWM, analog are the three 'logical' options - but there is little difference between step/dir and pwm as velocity controls go. you potentially gain differential signalling, but it'll probably be converted into analog inside the drive
[21:56:19] <bpuk> ReadError: Another example would be a lathe spindle, but that'd probably be velocity mode - unless you've got an indexing spindle, why send position information at all - read the position for threading, but otherwise run purely in velocity mode

[21:59:11] <bpuk> zeeshan: To be honest, if you are using modern drives with fieldbus (or similar) control and you can interface that to linuxcnc - why the heck not.
[21:59:31] <zeeshan> id like to do it for the experience
[21:59:38] <zeeshan> never played with modern drives
[22:00:12] <bpuk> they've gotta beat tacho's on the motors :P
[22:00:24] <zeeshan> haha
[22:00:49] <bpuk> that was a _horrible_ machine to fix - tacho's for speed feedback, LVDT's for position feedback *shudder*
[22:01:04] <zeeshan> my mill uses tachos :D
[22:01:13] <bpuk> aieeee!
[22:01:34] <bpuk> I'll stick with resolvers whenever I can :P

[22:03:27] <zeeshan> white thing is the arm?
[22:03:33] <Erant> Right.
[22:03:33] <zeeshan> L bracke t
[22:03:38] <Erant> It's bolted onto the head
[22:03:51] <Erant> Head's about 30lbs, probably.
[22:03:53] <Erant> Not that heavy
[22:04:20] <zeeshan> any reason you dont want to use steel?
[22:05:08] <Erant> My machine's a little limited, never done steel before. I'll probably use steel, but I was curious if I _had_ to.
[22:05:33] <zeeshan> just make i t double thickness :P
[22:06:05] <Erant> I almost have to anyway, to accomodate the ballnut...
[22:06:36] -!- motioncontrol has quit [Remote host closed the connection]
[22:06:46] <Duc> just take light cuts with your machine
[22:08:43] <Erant> Right, I was going to aim for ~6IPM.
[22:10:12] <Duc> how much material do you need to remove
[22:11:29] <Erant> Euhm, let's see. Couple of mounting holes, so that's just drilling.
[22:11:53] <Erant> Small counterbores, nothing major. The big hole is the one for the ballnut. Which is 3/4" in diameter, all the way through.
[22:12:58] <Duc> nothing sounds bad
[22:13:14] <Duc> just slowly increase drill bit sizes till you get to 3/4
[22:13:18] <jdh> or buy a bolt-on ballnut mount
[22:13:40] <bpuk> or use a boring head (if you have one)
[22:14:16] <Erant> I was going to just bore with a 3/8" end mill.
[22:14:29] <Erant> Or at least, after I run out of drill sizes.
[22:15:35] -!- chillly has quit [Quit: Ex-Chat]
[22:16:20] <Erant> Hmm... Is the ballnut going to reverse drive the screw (2mm lead) when the servo's off?
[22:18:05] <bpuk> Probably not. If it does, stick an adjustable gas spring under the head - release pressure until it holds still. That's assuming your servo isn't breaked
[22:20:21] <Erant> Sounds like a plan.
[22:21:05] <bpuk> if you were using linear guides - I'd guess it probably would - but on dovetails I wouldn't worry too much at this point

[23:12:00] <PetefromTn_> hehe
[23:12:13] <PetefromTn_> I was just out there working on the CNC lathe build
[23:12:31] <PetefromTn_> and I have been kind dreading a problem with the homes and limit switches
[23:12:58] <PetefromTn_> when I bought the machine all the electronics in the electronics cabinet was removed save for a few items
[23:13:32] <PetefromTn_> and the jackhole who gutted it just took a bolt cutter or something and cut all the wires where they enter into the electronics cabinet in these environmental connectors
[23:14:15] <PetefromTn_> I figured that I would be looking at cutting and splicing a BUNCH of wires together to be able to lengthen them to reach where they will be needing to go into the electronics cabinet
[23:14:46] <PetefromTn_> this would of course include the homes and limits which are those commercial sealed switches and heavy shielded wires
[23:14:55] <Duc> shit that sucks
[23:15:19] <PetefromTn_> Today I was crawling around under the machine trying to loosen up the wire chase end to remove and clean the wires and look into lengthening them
[23:15:36] <PetefromTn_> I found this access panel with like ten button head screws on it
[23:15:41] <PetefromTn_> I removed the panel
[23:15:48] <PetefromTn_> attached to the panel was a buss block
[23:16:22] <PetefromTn_> all of the wires that went to the carriage ended at this bus block and then pass thru continuing into the electronics enclosure
[23:16:54] -!- Loetmichel [Loetmichel!~cylly@p54B1054A.dip0.t-ipconnect.de] has joined #linuxcnc
[23:17:00] <PetefromTn_> So I was very pleased to know that all I will have to do is replace the wires FROM the buss block to the electronics cabinet which is probably something like six feet or so
[23:17:01] <CaptHindsight> and probably <6" from the spot he snipped them :)
[23:17:23] <PetefromTn_> yeah the guy just gutted and cut his way thru everything
[23:17:31] <PetefromTn_> I knew this when I bought it tho
[23:17:41] <Duc> can you fit a sealed tubing connector between the two panels
[23:17:53] -!- Loetmichel2 has quit [Ping timeout: 276 seconds]
[23:17:57] <PetefromTn_> the only real issue is there are several things coming the electronics cabinet from the headstock
[23:17:58] <CaptHindsight> there was a factory recycler near me that would buy up entire few year old factory floors....
[23:18:28] <PetefromTn_> there does not need to be any sealing here duc this is all INSIDE the base of the machine
[23:18:50] <Duc> ok
[23:19:01] <PetefromTn_> anyway there is a lubrication pump on the headstock back end that the guy cut the wires to
[23:19:03] <Duc> why did the guy cut the cables like that
[23:19:06] <CaptHindsight> filled with robots and CNC. The monkeys they hired to remove equipment would cut through anything and everything including control wiring to remove things
[23:19:07] <Duc> ssending to scrap
[23:19:10] <PetefromTn_> because he is an azzhole
[23:19:51] <PetefromTn_> so this lubrication pump goes into the headstock oil bath and there is a wire coming from it into the electronics cabinet
[23:20:01] <PetefromTn_> he cut it off just inside the cabinet
[23:20:12] <Jymmm> Yeah, cause he knows his shit and gonna spent 4 extra hours disconnecting and labeling each damn wire then sell it to you for les than he paid for it
[23:20:12] <CaptHindsight> until they realized that the monkeys were cutting through >$500 factory cables nd made testing and resell more difficult
[23:20:16] <PetefromTn_> so I will have to patch that one at the pump somehow and lengethen it
[23:20:51] <PetefromTn_> there is also the built in spindle encoder wires which were cut the same way just inside the electronics cabinet
[23:20:53] <Duc> I can only see the need to cut power cables to remove a machine
[23:21:04] <Jymmm> CaptHindsight: Testing "It powers up".
[23:21:16] <CaptHindsight> Duc: monkeys don't know that
[23:21:20] <PetefromTn_> that one won't be too bad tho because it has a barrel style connector on the sensor
[23:21:29] <PetefromTn_> I can just repin that and make it with a longer wire
[23:21:52] <PetefromTn_> there is another wire coming from the headstock that goes to the electronics cabinet. again it was cut
[23:21:56] <CaptHindsight> they treat robots like plants in the jungle, you just chop away until its free
[23:21:57] <PetefromTn_> not really sure what it is for
[23:22:07] <PetefromTn_> it just goes into the headstock casing
[23:22:21] <PetefromTn_> I have not pulled the headstock casing cover off yet to see what it is
[23:22:31] <PetefromTn_> probably a thermal sensor or something I suppose
[23:22:31] <Jymmm> PetefromTn_: IF they did it right, you couldn't afford the machine =)
[23:22:41] <PetefromTn_> probably not
[23:22:55] <PetefromTn_> None of this is a huge problem really
[23:23:10] <PetefromTn_> and most of the stuff is getting replaced with brand new cables and wires anyway
[23:23:14] <Jymmm> PetefromTn_: So next time you're doen there, just toss em a bunch of bananas and be happy about it =)
[23:23:56] <PetefromTn_> There is also a small harness that goes down to the tailstock end of the base where there is a coolant trough and this must have been for the coolant pump
[23:23:58] <CaptHindsight> http://www.thefirestore.com/store/product.aspx/productId/13089/Partner-K-12FD-Fire-Rescue-Saw-Saw-w-12-Blade/ this is all you need to remove CNC machines or robots
[23:24:30] <CaptHindsight> and a sledge hammer
[23:24:36] <PetefromTn_> That harness was also cut but luckily there was a lot of this cable kinda sitting inside the access panel and I think it is more than long enough to reach once I rearrange the routing a bit
[23:25:09] <PetefromTn_> I removed the slightly damaged cable chain protector from the machine today for the first time
[23:25:11] <Jymmm> CaptHindsight: 8lb maul is all you need
[23:25:18] <PetefromTn_> it has a bad spot near the end
[23:25:44] <PetefromTn_> I THINK I can cut that bad spot out and shorten it and still have full travel but I have to check it out
[23:25:50] <CaptHindsight> I'm surprised that they just didn't pull in with a backhoe and just started ripping
[23:26:01] <PetefromTn_> Right now I need to clean the gunk and shit off of it
[23:26:03] <Duc> is it a metal cable chain or plastic
[23:26:09] <PetefromTn_> and get it looking all pretty
[23:26:20] <Jymmm> CaptHindsight: It slices, it dices, it chops, it smashes... http://www.homedepot.com/catalog/productImages/400/6c/6c1e80aa-8a7b-4783-aa28-e78c8a830e52_400.jpg
[23:26:21] <PetefromTn_> it is actually a metal chain rectangular
[23:26:37] <PetefromTn_> it was probably quite nice at one point
[23:27:48] <PetefromTn_> I don't know what hit it but it is now not coolant proof in that area so I need to either shorten it if I can reach all the way with the shortened setup or replace it with something else
[23:28:39] <Duc> Should be a easy ebay item to find
[23:29:06] <PetefromTn_> maybe I have not tried yet dunno what you would search for
