Back
[00:09:18] <tjb1> I added an XML and it goes through the splash screen and the little temporary message from axis and then it all disappears without an error message
[00:09:20] <tjb1> any ideas?
[00:45:41] <Tecan> holy crow its full in here
[00:46:49] <tjb1> no one talks though lol
[01:02:46] <tjtr33> L84Supper, didja ever come across the table extrusion these mini mills all seem to use?
[01:02:48] <tjtr33> like http://www.joyfay.com/us/desktop-cnc-router-engraver-drilling-milling-engraving-machine.html ?
[01:06:08] <tjtr33> nm http://www.technocomponents.com/LMC/Extrusions/
[01:47:25] <Jymmm> L84Supper: Did you say you can mix polymers?
[02:13:38] <DJ9DJ> moin
[02:44:26] <Loetmichel> mornin'
[04:45:25] <r00t4rd3d> nite
[07:01:49] <L84Supper> Jymmm: yes, blend, make, mix etc
[08:12:39] <Jymmm> L84Supper: Got anything that withstand high heat and is food safe?
[08:13:42] <L84Supper> Jymmm: a polymer or photopolymer?
[08:13:47] <Jymmm> L84Supper: silicone? phenolic? something else?
[08:14:22] <Jymmm> L84Supper: I have a water bottle and want to replace the threaded cap with somethign heat resistant
[08:15:35] <L84Supper> Jymmm: do you want to machine it, cast it, print it?
[08:16:16] <Jymmm> L84Supper: Well, I only need two of them and dont have a mill
[08:17:28] <mk0> fluoroplastic; ftoroplast?
[08:17:41] <mk0> dunno how right in english
[08:17:48] <Jymmm> food safe
[08:18:01] <mk0> isn't it?
[08:18:02] <Jymmm> mk0: you mean teflon?
[08:18:46] <Jymmm> "fluoro" usually isn't at high heat
[08:18:49] <L84Supper> how high a temp range?
[08:18:54] <mk0> maybe. in vocabulary it's a synonym. polytetrafluorethylene
[08:19:02] <Jymmm> Literaly thrown in a fire
[08:19:11] <mk0> об no then
[08:19:26] <mk0> 400 deg C
[08:19:54] <L84Supper> sand cast aluminum within your range of ability or desire?
[08:20:15] <Jymmm> I want to be able to booil water in the SS bottle and route the steam off
[08:20:34] <Jymmm> basically making a stile
[08:21:19] <L84Supper> make a mold of the cap, max wax mold, sand cast or ask somebody here to machine two for you :)
[08:21:28] <L84Supper> max/make
[08:21:47] <Jymmm> maybe I can just use silicone
[08:22:09] <Jymmm> I just wanted something a lil more denser
[08:23:18] <L84Supper> http://www.jbweld.com/product/j-b-highheat/ is good to 400 F
[08:23:44] <Jymmm> actaully 550F, but not food safe
[08:24:21] <L84Supper> cast or machine something
[08:24:51] <L84Supper> even ceramics
[08:25:02] <Jymmm> I think casting will be simplest, just need to figure out what to cast it in
[08:25:17] <L84Supper> make a latex or silicone mold
[08:25:21] <Jymmm> Needs to be more durable
[08:25:32] <L84Supper> you have the original cap as a mold
[08:25:41] <Jymmm> yep
[08:25:43] <L84Supper> to cast two?
[08:25:53] <Jymmm> to withstand abuse
[08:26:42] <Jymmm> I want to go backpacking and be able to desalinate water
[08:27:42] <L84Supper> I'm pretty sure they sell aluminum bottles with aluminum caps
[08:28:04] <Jymmm> al always taste nasry
[08:28:16] <Jymmm> nasty. That's why i use SS
[08:28:22] <L84Supper> anodize it
[08:28:35] <Jymmm> SS works for me
[08:28:47] <Jymmm> doens't melt when toss in the fire either =)
[08:29:01] <L84Supper> I like you Jymmm
[08:29:09] <L84Supper> you answer your own questions
[08:29:33] <Jymmm> Not yet,
[08:31:06] <Jymmm> Silicone is food safe and will withstand high temp, but it's not durable to things like nicks and abrasion. What I needed from you L84Supper is some polymer or addistive for solicone to make it more durable to abuse
[08:31:39] <L84Supper> are you willing to order a 200kg drum of the stuff?
[08:32:05] <Jymmm> not really =)
[08:32:52] <Jymmm> L84Supper: But... I could order samples =)
[08:32:59] <L84Supper> that's the fun of working with these components, the suppliers only like to sell in drums
[08:33:30] <L84Supper> 4-5 or more components in a blend
[08:34:02] <L84Supper> 250 gallons to make the 8oz somebody would like :)
[08:34:04] <Jymmm> an assoerment evaluation sampler =)
[08:34:20] <Jymmm> just like chocolates =)
[08:35:18] <L84Supper> high temp polymer sampler assortment ...... now in 1800, 8oz bottles
[08:35:47] <Jymmm> 1 please
[08:36:29] <Jymmm> L84Supper: But, what would I be getting?
[08:40:45] <L84Supper> http://tinyurl.com/c3lk7k8 Stainless steel sanitary bottle; 1 liter, 3" flange $920.00 USD
[08:41:06] <Jymmm> your funny
[08:41:18] <L84Supper> http://www.coleparmer.com/Category/Stainless_Steel_Sanitary_Bottles/5534 different sizes
[08:41:54] <Jymmm> I have 1200mL SS bottles already, I need the high heat cap =)
[08:42:13] <Jymmm> I think I found something.... Silicone stoppers
[08:42:40] <Jymmm> http://www.coleparmer.com/buy/product/4306-high-purity-silicone-stopper-size-6d.html
[08:42:41] <L84Supper> I'm still not really sure what you are looking for
[08:45:35] <Jymmm> The caps I have are made from abs/pvc, at the very least they will leech plasticizers into the water when heated on a fire
[08:51:27] <Jymmm> L84Supper: Fuck it, I'll make from duct tape =)
[08:52:19] <skunkworks> cork?
[08:52:21] <skunkworks> :)
[08:52:36] <Jymmm> skunkworks: burns in fire =)
[08:53:01] <skunkworks> fosslized cork?
[08:53:10] <Jymmm> lol, there we go =)
[08:53:37] <Jymmm> Could use bakelite too (phenolic)
[08:54:58] <skunkworks> Mmmm the smell of bakelite... (used to have bakelite circuit board stock when I was a kid..)
[08:55:06] <Jymmm> BEER TO THE RESCUE!!!!!!! http://www.williamsbrewing.com/10-VENTED-SILICONE-STOPPER-P2667.aspx
[08:56:56] <L84Supper> oh, so you're just looking for a 400 C food safe silicone gasket
[08:57:05] <L84Supper> why didn't you just say so?
[08:57:24] <Jymmm> Not gasket, screw cap
[08:57:41] <Jymmm> and I DID SAY! You just didn't listen =)
[08:58:42] <L84Supper> a SS cap will hold up better
[09:01:18] <Jymmm> http://i.ebayimg.com/t/Rare-41-Oz-1200mL-SUBZERO-Water-Bottle-Stainless-Steel-Carabiner-Blue-/00/s/MTYwMFg5MDA=/$T2eC16hHJF8E9nnC9bTIBQB%28OWHdY!~~60_35.JPG
[09:01:20] <L84Supper> if i was counting on using saltwater and desalinization to stay alive, I'd rather have a SS cap
[09:02:34] <L84Supper> http://www.youtube.com/watch?feature=player_embedded&v=kmxaqvLvS0E P2i hydro-phobic nano-coating technology, makes all electronics water-resistant
[09:02:54] <Jymmm> so does wd40
[09:06:31] <L84Supper> Parylene and this new one last far longer, longer than the typical life of a cell phone
[09:06:45] <Jymmm> ah
[09:07:35] <skunkworks> he has a cnc and rotory axis - why is he offsetting the crank to make the journals? :)
[09:07:39] <L84Supper> so if you drop your phone in the water, you can just shake it off
[09:07:47] <skunkworks> could all be done with one setup
[09:08:32] <Jymmm> Damn back seat irc drivers
[09:10:31] <r00t4rd3d> I cut a 296 word poem last night, while I was cutting the border, the last thing to be cut, my machine crashed into one of my clamps and stalled my machine.
[09:10:44] <r00t4rd3d> ruined
[09:11:50] <L84Supper> any video?
[09:12:01] <r00t4rd3d> no.
[09:12:14] <L84Supper> yesterday was cnc crash videos day :)
[09:12:30] <Jymmm> Yeah! Just like nascar, we wanna see the crash n burn videos!
[09:12:43] <r00t4rd3d> i might take a pic of the fucked up piece
[09:12:52] <r00t4rd3d> i dont even want to look at it atm
[09:13:06] <r00t4rd3d> 3.5 hours of cutting
[09:13:11] <r00t4rd3d> 30F
[09:13:33] <r00t4rd3d> and i got to do it again today :(
[09:13:50] <Jymmm> Lather, Rinse, Repeat

[10:37:44] <tjb1> JT-Shop:
[10:38:01] <JT-Shop> aye
[10:38:27] <tjb1> I had to edit comp file a bit
[10:38:28] <tjb1> http://pastebin.com/CEnTHmfD
[10:38:46] <tjb1> Also got the XML to work
[10:45:37] <JT-Shop> \cool
[10:51:07] <tjb1_> Just confused a bit about how to pass the Z back and forth
[10:53:32] <JT-Shop> what do you mean by pass the Z back and forth?
[10:54:32] <tjb1_> I remember before there were a few z lines added to hal
[10:54:59] <JT-Shop> all the connections are in the description
[10:56:14] <tjb1_> Id have to look at my old HAL
[10:57:19] <tjb1_> http://pastebin.com/KWz7FDBJ
[10:57:22] <tjb1_> Those specifically
[10:58:04] <JT-Shop> what's the question?
[10:58:51] <tjb1_> I can just change those to thc instead of thcud ?
[10:59:00] <JT-Shop> yea
[10:59:20] <tjb1_> Awesome, might be done then!
[11:21:34] <IchGuckLive> hi B)
[11:26:22] <IchGuckLive> today i got 15 new OLD pc for the education room and they got a gigantic 8k latency as the old ones im driving at 50k
[11:26:42] <IchGuckLive> i looked on ebay they are sold at 60 euros
[11:34:44] <IchGuckLive> folks is it more performance when i disable hypertread ?
[11:42:40] <skunkworks> https://www.youtube.com/watch?v=qtiR2-SHlus
[11:42:56] <skunkworks> IchGuckLive, usually
[11:45:08] <IchGuckLive> Thanks nice mashine
[11:45:34] <IchGuckLive> thinks you never imagine are doone by linuxcnc
[11:46:23] <IchGuckLive> skunkworks: sounds like bruce from brasil
[11:46:29] <IchGuckLive> in the vid
[11:48:29] <AR__> i need meth
[11:49:20] <IchGuckLive> skunkworks: isent HT in bios
[11:50:00] <skunkworks> yes
[11:50:03] <skunkworks> if it is an option.
[11:51:54] <IchGuckLive> the cat prog/cpuinfo sees a flag HT so i think its hypertread but i cand find it in bios
[12:01:17] <IchGuckLive> in our wikipedia latency page are there test presets for the numbers or only the run itself
[12:14:36] <R2E4> Is there a list of compatible mpgs?
[12:18:46] <IchGuckLive> R2E4: there is a list of hardware in the ewikipedia
[12:28:03] <L84Supper> who has the best prices on NSF / FDA approved HDPE and PP sheet?
[12:36:39] <r00t4rd3d> walmart
[12:36:44] <r00t4rd3d> cutting boards :D
[12:37:01] <IchGuckLive> homedepo has always good pp
[12:37:32] <L84Supper> yeah, for small sheets it's the way to go up to ~3/8"
[12:41:55] <L84Supper> need to make a 3-axis stage with 1.5" travel out of HDPE
[12:42:32] <andypugh> hexapod! (with flexure joints)
[12:43:28] <IchGuckLive> L84Supper: you are in canada wright
[12:43:46] <L84Supper> US and China, depending on my mood :)
[12:44:14] <IchGuckLive> ah china is on holiday kt is aeays drunk O.O
[12:44:36] <L84Supper> spring festival is over
[12:45:37] <IchGuckLive> till 3.3
[12:45:56] <IchGuckLive> so one week to go to normal workflow
[12:46:02] <L84Supper> maybe in a different China
[12:46:09] <IchGuckLive> Hk
[12:46:38] <Loetmichel> chinese new year is done almost two weeks
[12:46:50] <Loetmichel> that must be a HELL of a hangover ;-)
[12:47:12] <IchGuckLive> we ask him why if he joins in ktchk
[12:47:13] <L84Supper> it is actually one of the times that most people have a drink
[12:47:26] <mrsun_> hmm anyone here have a south bend lathe? :)
[12:47:32] <mrsun_> might have asked that before ..
[12:51:56] <archivist> and you should remember
[12:52:20] <WalterN> L84Supper: oh, how is new material laser sintered BTW?
[12:52:24] <WalterN> I mean
[12:53:04] <WalterN> with laser sintering, a laser sweeps the surface, then an arm or something goes across the surface depositing material across the top?
[12:53:56] <mrsun_> archivist, but i dont .. i forget everything all the time :P
[12:55:54] <archivist> you forgot I took my tailstock apart for pictures!
[12:56:38] <mrsun_> ahh yes! =)
[12:56:54] <mrsun_> i remembered someone did it but not who :P
[12:56:57] <mrsun_> thanks alot for that =)
[12:57:18] <mrsun_> archivist, does it have "standard" south bend compound rest hole etc? :)
[12:57:33] <xxoxx> is Smithy's any good ?
[12:58:19] <archivist> probably standard on mine
[12:58:26] <mrsun_> http://www.desmoines-classifieds.com/Warren-County-/Farm-Supplies-/Road-building-/South-bend-9-10K-lathe-compound-rest-w-nut-gib-adimage.jpg that hole
[12:58:45] <mrsun_> and if you know what the pins are made of, are they hardened? brass etc? :)
[13:02:25] <archivist> mrsun_, yes I think mine is similar http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_06_15_Adcock_Shipley/IMG_1250.JPG
[13:03:30] <archivist> never had mine out
[13:04:43] <andypugh> xxoxx: They are pretty well integrated to LinuxCNC.
[13:05:08] <xxoxx> ok. I am thinking about getting one.
[13:06:58] <andypugh> I think their EZ-Trol is linuxCNC with a different GUI, but I could be wrong.
[13:07:29] <xxoxx> oh...
[13:07:38] <L84Supper> WalterN: http://www.youtube.com/watch?v=SVkUwqzjGJY&feature=youtu.be
[13:08:37] <WalterN> L84Supper: ah, yeah... herm
[13:09:07] <xxoxx> I only got a C0 baby lathe right now. Thinking about getting a full size one.
[13:09:08] <WalterN> is that sweeping roller thing hard to make correctly?
[13:09:19] <andypugh> xxoxx: I would certainly want to see one in action before spending the money.
[13:09:27] <xxoxx> ok
[13:10:03] <L84Supper> WalterN: not really, if you can make the router you were talking about
[13:10:15] <xxoxx> I see Smithy's adverts in magazines a lot
[13:10:20] <andypugh> I am actualkly more a fan of old machine tools, made when Iron was cheaper.
[13:10:41] <WalterN> L84Supper: how thick typically is the deposited powder thickness?
[13:11:06] <archivist> old iron is so much better :)
[13:11:26] <L84Supper> WalterN: http://www.youtube.com/watch?v=88BPmL8cGAo does it a little differently
[13:11:38] <andypugh> The problem is finding something that is nice enough to convert, but not too nice to dismantle :-)
[13:11:44] <xxoxx> I wonder if metal powder sintering is within reach of small shop / hobbyists ?
[13:12:05] <xxoxx> or die casting
[13:12:10] <andypugh> I am sure it is, have you seen the stuff that some hobbyosts do?
[13:12:31] <xxoxx> andypugh, true
[13:13:03] <L84Supper> WalterN: 0.1mm or less, pretty much down to the average particle dia. if you want
[13:13:40] <WalterN> L84Supper: is it typically variable?
[13:13:43] <andypugh> This is looking like a bargain: http://www.ebay.co.uk/itm/Bridgeport-Romi-EZ-Path-CNC-Lathe-/190803529045?pt=UK_Home_Garden_PowerTools_SM&hash=item2c6cc6cd55
[13:14:23] <L84Supper> WalterN: you usually set the z-axis res to the same thickness during a print
[13:14:48] <L84Supper> sice you have to slice the 3d model into layers, what you slice you need to match with on the printer
[13:15:53] <L84Supper> DIY plastic powder SLS http://www.youtube.com/watch?v=uu6Lemm_Dts
[13:16:05] <xxoxx> oh.. cool
[13:16:47] <L84Supper> nice lathe for ~$1k
[13:17:11] <WalterN> interesting
[13:17:22] <WalterN> they used a 200watt laser for metal SLS
[13:18:11] <IchGuckLive> 60w co2 is enoph at 400USD
[13:18:23] <IchGuckLive> for titanium powder
[13:18:47] <L84Supper> all depends on speed, particle size, etc etc
[13:19:34] <WalterN> I want 100 watts :P
[13:20:19] <WalterN> because why not
[13:20:41] <WalterN> I should call Matt and see if he wants to sell his unfinished 100 watt laser project
[13:32:43] <xxoxx> FDM for now. will try SLS later on
[13:33:44] <xxoxx> focusing on CNC permanent mold -> wax mold -> investment cast
[13:33:56] <WalterN> hmm
[13:34:24] <xxoxx> small batch (500 parts) precision aluminum jobs
[13:34:30] <WalterN> how much does a commercial plastic SLS type machine typically cost?
[13:35:00] <xxoxx> WalterN, I've only investigated DIY home-built type SLS rig
[13:35:16] <xxoxx> commercial grade might be quite expensive. unlike FDM
[13:35:36] <WalterN> xxoxx: how much does DIY cost then?
[13:35:38] <xxoxx> perhaps we need a SLS-Replicator
[13:35:51] <xxoxx> WalterN, within $2k
[13:35:58] <WalterN> what kind of laser?
[13:36:12] <xxoxx> carbon laser ?
[13:36:35] <xxoxx> CO2
[13:36:39] <WalterN> the one I'm thinking about using would cost about $1,000 just for the tube I think
[13:37:10] <WalterN> not sure about the power supply
[13:37:15] <xxoxx> I've only looked at jewlery-maker style/size machine
[13:37:46] <WalterN> oh yeah, I would want a couple feet of movement in both x and y
[13:38:00] <WalterN> maybe more
[13:38:24] <xxoxx> I see
[13:38:55] <xxoxx> I am only looking maybe 6 inch of movement, but high precision
[13:39:09] <WalterN> ballscrews++
[13:39:19] <xxoxx> Isn't Replicator coming out with SLS ?
[13:39:31] <xxoxx> I thought I heared from a while ago.
[13:40:09] <xxoxx> Replicator-SLS would be sweet.
[13:40:28] <WalterN> is replicator a company?
[13:41:05] <WalterN> ohhhh hermm
[13:41:15] <WalterN> I wonder if...
[13:41:18] * WalterN thinks
[13:41:46] <WalterN> rapid prototyping, laser printer style?
[13:42:11] <JesusAlos> hi
[13:43:45] <xxoxx> Replicator is a 3D printer
[13:44:41] <WalterN> xxoxx: a specific kind?
[13:44:51] <xxoxx> yes. it's very popular
[13:45:06] <xxoxx> open-source too
[13:45:20] <xxoxx> http://store.makerbot.com/replicator.html
[13:45:47] <xxoxx> I have a Replicator clone. Makes nice plastic parts
[13:46:46] <WalterN> 5 liters of volume? thats tiny
[13:46:54] <xxoxx> yeah
[13:47:02] <xxoxx> any bigger would take too long to print
[13:47:13] <xxoxx> 3D printers presently are quite slow
[13:47:44] <WalterN> hmm
[13:48:38] <xxoxx> snail's pace
[13:53:24] <mrsun_> hmm if i run into "carbides" in cast iron, will i ruine my hss tooling ?
[13:53:37] <WalterN> I'll have to think about SLS methodologies for a while to mentally build such a machine
[14:00:21] <L84Supper> it's doubtful that makerbot will make a SLS printer
[14:01:09] <L84Supper> they are targeting the low end consumer hype only makes parts with one material market
[14:01:24] <WalterN> time to go see about getting some parts for my car
[14:03:27] <xxoxx> http://www.cnczone.com/forums/casting_metals/51763-aluminium_manual_die_casting_technique.html
[14:03:36] <xxoxx> good article on DIY metal casting
[14:03:42] <xxoxx> good thread I mean
[14:15:59] <Tom_itx> andypugh, I saw the video
[14:16:40] <Tom_itx> does it look right?
[14:20:32] <R2E4> Would it be worth trying to convert an old colchester student lathe to cnc with linuxcnc?
[14:20:33] <L84Supper> one of the most popular applications for SLA is lost wax casting, the photopolymers burn out just like wax
[14:20:47] <L84Supper> all those parts shown at that link would be easy, features down to 50um are possib;e with DLP or laser
[14:23:33] <andypugh> Tom_itx: Yes, it looks good.
[14:23:46] <andypugh> I need to make a metal-spinning tool now, and then I will give it a try.
[14:23:51] <Tom_itx> did you run my updated file or one you modded?
[14:24:06] <andypugh> I slightly modded your second file.

[14:24:14] <L84Supper> http://www.makeyourownjewelrysite.com/blog/
[14:24:17] <andypugh> (there was a funny out-of-sequence cut)
[14:25:03] <Tom_itx> were the retracts ok at the profile ends?
[14:25:26] <andypugh> L84Supper: Is that a real site, or a penis enlargment thing?
[14:26:35] <Tom_itx> that out of sequence cut may have been when i grouped the tool and resequenced it
[14:26:38] <cradek> a weird combination
[14:26:40] <Tom_itx> i could have missed a path
[14:27:08] <andypugh> It was obvious enough on the Axis preview, so no problem.
[14:27:38] <Tom_itx> when i do a tool offset and repeat it always generates the paths in reverse order
[14:28:01] <Tom_itx> so i always have to reverse them and once in a while i miss one
[14:28:16] <andypugh> That sounds annoying.
[14:28:29] <Tom_itx> well it kinda is but i've grown used to it
[14:28:37] <andypugh> Isn't CAM meant to just work?
[14:28:44] <Tom_itx> it's not the cam
[14:28:48] <Tom_itx> it's the cad part
[14:28:57] <andypugh> Ah, OK.
[14:28:59] <Tom_itx> i got the cam working pretty good i think
[14:29:10] <Tom_itx> i didn't edit that at all
[14:29:13] <Tom_itx> the gcode
[14:29:28] <andypugh> Anyway, many thanks, and I need to get back to it, as the whole thing ideally wants to be done by saturday night...
[14:29:41] <Tom_itx> heh good luck spinning it
[14:30:06] <Tom_itx> take an old and new pic
[14:30:16] <L84Supper> http://www.youtube.com/watch?feature=player_embedded&v=Yyx7RXIy3ng nothing like using a torch inside a wooden box, what could go wrong?
[14:34:56] <Connor> Just got my powerCON plugs and sockets in.. They're pretty cool
[15:06:10] <Tom_itx> andypugh, i see what you mean on that out of sequence move. I'm not sure how that happened really
[15:06:21] <andypugh> Connor: Told you they were nice connectors
[15:06:35] <Tom_itx> about 7 or 8 cuts in from the finish
[15:06:46] <andypugh> Airtight too. Not sure why that would be improtant in CNC, but still.
[15:07:29] <Connor> Airtight ?
[15:07:31] <Connor> You sure ?
[15:07:39] <andypugh> Yes, thats the one. Line 2721 from memory?
[15:08:01] <andypugh> Connor: Sockets, I believe so. The contacts are moulded in.
[15:08:16] <andypugh> Right, spinning tool forging, step 2....
[15:08:21] <Tom_itx> dunno, i'm looking at the model
[15:08:41] <Tom_itx> it posted what it saw
[15:09:34] <Tom_itx> it's odd that got out of sequence there though since it was auto generated
[15:19:38] <mrsun> making a tapered gib, wouldnt that just be putting a piece of flat on an angle, mill it or whatever to that angle say 1 degree, then just side cut them like any ordenary gib? :)
[15:20:45] <mrsun> or am i trying to simplify it to much? :P
[15:32:43] <andypugh> mrsun: https://plus.google.com/photos/108164504656404380542/albums/5397760774091143489
[15:33:07] <andypugh> (step-by-step making tapered gibbs for my lathe_
[15:33:27] <mrsun> yes but those are not for dovetails :P
[15:33:43] <mrsun> but shouldnt the process be the same but i would have to mill the angles on the sides also ?
[15:34:05] <andypugh> Well, I cheated by making the two parts together so that they _had_ to fit.
[15:34:30] <andypugh> Do the existing dovetails have a taper?
[15:34:37] <mrsun> no
[15:34:39] <mrsun> =)
[15:34:53] <andypugh> Well, a tapered gibb won't fit then...
[15:35:08] <andypugh> "folding" gibs might work.
[15:35:16] <mrsun> andypugh, well im modifying :P
[15:35:22] <mrsun> so the dovetail will be tapered
[15:37:12] <andypugh> Good luck with that.
[15:37:25] <mrsun> why ? :)
[15:37:41] <mrsun> shouldnt it only be to put it in at an angle and remill the dovetails =)
[15:37:59] <mrsun> problem is that i know it got carbide in it ... so hss dovetail cutters might not cut it :P
[15:38:02] <mrsun> literaly
[15:38:20] <andypugh> Do you have a dovetail cutter?
[15:39:02] <mrsun> i have but not the right angle but i would order one if i start the project =)
[15:39:07] <mrsun> its 55 degrees on the milling machine
[15:39:11] <mrsun> got 45 and 60 :P
[15:39:17] <andypugh> I guess you could cut one dovetail at an angle, glue in the tapered gib, then machine both dovetails at the same setting to make sure they are exactly parallel. Then scrape a lot.
[15:39:33] <andypugh> Then release the glue with heat.
[15:41:04] * skunkworks waits for andypugh to reply to his dividing head thread
[15:45:08] <Tom_itx> andypugh, have you run the inner one yet?
[16:01:11] <Tom_itx> andypugh, i posted a new inner file. i added a couple extra cuts at the beginning. it looked like the tool could have gouged the corner of the material at the beginning
[16:01:44] <Tom_itx> depending on the stock size you started with
[16:04:09] <Tom_itx> 176.2 mm diameter is what i used on that one

[17:33:56] <Valen> inyrtrdyinh
[17:34:01] <Valen> bah
[17:34:04] <Valen> interesting
[17:34:18] <Valen> only 3.2nm though?
[17:34:19] <andypugh> $US 126 shipping too
[17:34:41] <Valen> dmm said they would under value the packing slip so it'll go through customs
[17:34:44] <andypugh> Lots more on there.
[17:35:18] <Valen> I always get worried buying stuff from china
[17:35:28] <skunkworks> logger[psha]:
[17:35:30] <logger[psha]> skunkworks: Log stored at http://psha.org.ru/irc/%23linuxcnc/2013-02-27.html
[17:36:22] <andypugh> Aye. I would be a lot more comfortable with DMM. They have at least been in business for several years.
[17:37:46] <Valen> I'll have to give the local allen bradley and baldour reps a call
[17:37:54] <Valen> I have a feeling i should be sitting down
[17:38:26] <cradek> stupid forum "subscribes" me by default and I always forget to uncheck it
[17:38:29] <andypugh> Maxon too. :-) (maybe lie down)
[17:38:42] <Valen> do maxon go up to that power level?
[17:38:51] <andypugh> Probably not.
[17:38:57] <Valen> 0.72nm i could probably get from them for the same price
[17:39:10] <Valen> they do make nice stuff though
[17:39:32] <andypugh> Maxon go up to 400W
[17:40:47] <andypugh> Servos have low torque relative to steppers. But they have that torque to high speeds, so it is more effective (especially as 5:1 gearing is probably fine)
[17:41:39] <Valen> last time i looked at maxon a 5W motor driver was $250
[17:43:22] <Valen> super helpfull guys there though
[17:43:57] <Valen> got me out of a pickle i was having with a cheap made in china motor
[17:44:03] <Valen> (it ate the brushes)
[17:44:12] <andypugh> They have online pricing. (which is pretty unique). 13mm 6W brushless is CHF162.70. (which is £114)
[17:44:31] <Valen> put the motor on the scope, had about 4v of noise (which was good with a 3v supply)
[17:44:41] <Valen> put the maxon in ~.05v of noise
[17:45:05] <Valen> 167131 EC 60 Ø60 mm, brushless, 400 Watt, CE approved, with Hall sensors 60 mm 400 W 48 V 3100 rpm 830 mNm CHF 1,008.70
[17:45:08] <andypugh> Yes, we used to use them a lot in a previous job. The technical help more than made up for the higher price in 1 to 6 offs like we made.
[17:51:54] <andypugh> I wonder what this is? I am tempted to buy it to find out: http://www.ebay.co.uk/itm/Shaft-To-Digital-Encoder-Librascope-713-18-8-Used-/330859627467?pt=UK_CPV_Aviation_SM&hash=item4d08c543cb
[17:55:33] <andypugh> skunkworks: re the cnczone thread, I don't see much to respond to. The last guy was largely correct, in a way that is irrelevant.
[17:56:14] <Valen> did you see that briefcase mill?
[17:56:29] <DaViruz> soo, an encoder that fits onto a 28mm hollow shaft, any chances of finding one?
[17:57:02] <andypugh> Maybe
[17:57:46] <andypugh> I have a 27mm dia resolver sat on my desk
[17:59:07] <DaViruz> i'm thinking a toothed wheel and a reading fork, but i really would prefer a more enclosed solution (that i don't have to build myself)
[18:00:07] <DaViruz> perhaps a toothed belt sprocket and an encoder mounted off to the side. but i suppose i need to take the stresses of the encoder for that
[18:00:53] <DaViruz> http://www.ebay.com/itm/Heidenhain-rotary-encoder-RON-786C-36000-ID-355884-22-/121072941380?pt=LH_DefaultDomain_0&hash=item1c30827944
[18:00:57] <DaViruz> oh deer..
[18:01:00] <andypugh> How about one of the magnetic ones?
[18:02:16] <DaViruz> want to elaborate?
[18:02:48] <andypugh> OK, bit first: http://www.cui.com/Product/Components/Encoders/Incremental_Encoders/Shaft/MES3_Series is 5mm dia
[18:03:56] <andypugh> Magnetic ones: http://www.ams.com/eng/Products/Magnetic-Position-Sensors/Magnetic-Rotary-Position-Sensors
[18:04:38] <DaViruz> oh.
[18:06:08] <DaViruz> interresting, but i don't think i want to fiddle around with it
[18:07:04] <andypugh> The tiny CUI one looks good then
[18:09:19] <andypugh> Or there is a 20mm OD hollow shaft one that might be easier to mount.
[18:10:00] <DaViruz> i'm not sure what to do with the tiny one
[18:11:15] <andypugh> They have many types, one ought to suit: http://www.cui.com/Catalog/Components/Encoders/Incremental_Encoders
[18:11:54] <L84Supper> r00t4rd3d: the RTAI main dev just announced it earlier today
[18:12:49] <DaViruz> sure, they have a bunch, i just don't see one that's going to fit over a 28mm shaft
[18:14:47] <DaViruz> maybe i wasn't entirely clear, the idea was to have an encoder with a hollow shaft that fits over my 28mm hollow shaft
[18:16:00] <andypugh> Ah! I thought you only had 28mm to play with!
[18:17:59] <DaViruz> it's for my lathe spindle
[18:18:19] <andypugh> So, cheap would be good too?
[18:18:49] <DaViruz> it would help
[18:19:08] <DaViruz> the heidenhein $3500 one is a little bit over the top
[18:19:17] <DaViruz> http://www.wallacecompany.com/cnc_lathe/HNC/00010-1a.jpg
[18:19:24] <DaViruz> i'm kind of liking that solution though
[18:21:11] <andypugh> I made my own.
[18:21:22] <andypugh> Is it for threading, or indexing?
[18:21:30] <DaViruz> threading
[18:21:37] <andypugh> (for threading in LinuxCNC you don't need all tha many slots
[18:22:09] <DaViruz> my lathe was built fron scratch by an old dentist, there realy isn't any good place to place an open windowed wheel
[18:23:06] <andypugh> Ah, so http://www.ebay.com/itm/Woodlathe-indexing-system-for-1-inch-spindles-/360288173252?pt=LH_DefaultDomain_0&hash=item53e2d93cc4 is not going to help?
[18:24:33] <andypugh> Belt-drive to a conventional encoder seems pretty common, that's what Hardinge do too.
[18:25:22] <DaViruz> i don't think i'm going to use linuxcnc for this though
[18:25:42] <DaViruz> i just want synchronized z feed
[18:25:54] <DaViruz> seems a bit overkill
[18:27:01] <skunkworks> DaViruz: but cheap and already done :)
[18:27:21] <skunkworks> I would use linuxcnc for everything if I could
[18:30:07] <r00t4rd3d> L84Supper, source?
[18:31:34] <DaViruz> yeah i know it works good, but i don't really want to tie the lathe up to a computer i have to boot just to use it, i still want to use it strictly manually
[18:32:17] <DaViruz> it can't be that complicated to have a microcontroller output pulses synced and scaled to incoming pulses
[18:39:45] <andypugh> DaViruz: No, I think there are widgets that do it. Integer maths might not be enough, beware of rounding errors.
[18:41:01] <andypugh> If you used servos then you could still use the lathe manually. (I have steppers on mine, and I can only turn the manual handles slowly)
[18:42:50] <DaViruz> oh? i ordered a stepper with dual shafts thinking i'd be in the clear
[18:43:38] <DaViruz> does it cause too much "drag" even unpowered?
[18:43:51] <andypugh> It might depend on the drives.
[18:44:03] <andypugh> Open-circuit they twirl freely.
[18:44:32] <DaViruz> oh.
[18:44:53] <DaViruz> i'll have to check and see how my other steppers on geckos handle
[18:45:02] <andypugh> It doesn't stop you turnign the handles, it just feels a bit odd.

[21:51:51] <L84Supper> 256mb ram and 10gb hd's
[21:52:06] <L84Supper> must be from 98 or so
[21:52:18] <pfredx1> this thing has a 400GB HDD in it it is from 2007
[21:52:53] <pfredx1> in 98 I had an 800MHz athlon thunderbird
[21:52:58] <L84Supper> 99-00 iirc
[21:53:27] <pfredx1> it was the chip that came out before the K6 I think
[21:53:35] <L84Supper> you were livin big
[21:53:59] <pfredx1> well I wanted the 1 Ghz but it was so much money I took the middle of the road one
[21:54:14] <pfredx1> I ran that PC for 10 years
[21:54:28] <pfredx1> then the PSU went on it and killed all of the caps on the motherboard
[21:54:47] <pfredx1> I went to it one morning and it was a brick
[21:54:53] <L84Supper> June 5, 2000 The second generation Athlon, the Thunderbird, debuted
[21:55:03] <pfredx1> yeah I had the first gen one
[21:55:19] <pfredx1> but I could swear it was called a thunderbird
[21:55:26] <L84Supper> Athlon processor launched on June 23, 1999
[21:55:32] <pfredx1> maybe it was the 2nd gen one?
[21:55:56] <pfredx1> let me see i have it right here
[21:56:16] <L84Supper> K6-2 was an x86 microprocessor introduced by AMD on May 28, 1998
[21:56:28] <L84Supper> http://en.wikipedia.org/wiki/AMD_K6-2
[21:56:50] <L84Supper> http://en.wikipedia.org/wiki/K7_(microarchitecture)
[21:57:03] <pfredx1> nope it must still be in that motherboard down in the lean to
[21:57:20] <pfredx1> I thought about recapping the board
[21:58:06] <pfredx1> but it would have cost me like $40
[21:58:35] <Valen> halfway to a new atom board there
[21:58:44] <pfredx1> not then
[21:59:33] <pfredx1> I ran a 2 GHz P4 I picked up at the dumps for a while
[21:59:58] <pfredx1> but it just got too slow so I bit the bullet and bought an i3
[22:00:09] <L84Supper> http://www.newegg.com/Product/Product.aspx?Item=N82E16813157324 $54.99
[22:00:25] <jdh> I ditched the dual athlon on my router for an atom
[22:00:27] <L84Supper> ASRock E35LM1 AMD E-240 APU AMD A50M Mini ITX Motherboard
[22:01:21] <pfredx1> to get that board to run you need RAM and a PSU
[22:01:44] <pfredx1> oh and some kind of storage too
[22:07:52] <pfredx1> this is strange this machine won't read one of my flash drives
[22:56:51] <pfred1> I guess i should download a new LinuxCNC image
[23:01:35] <r00t4rd3d> L84Supper, you get any of that to work?
[23:02:03] <L84Supper> r00t4rd3d: any of what?
[23:11:51] <L84Supper> does anyone make a complete 5 axis rotary table? 500mm x 300mm x 100mm min
[23:12:22] <pfred1> what is that in English?
[23:12:44] <L84Supper> let me know what part you need translated
[23:12:54] <pfred1> 500mm x 300mm x 100mm
[23:13:31] <L84Supper> that would be the travel of the 3 main axis
[23:13:58] <L84Supper> since 4 and 5 are rotary
[23:14:28] <pfred1> we don't use the metric system in America
[23:14:39] <L84Supper> really
[23:15:11] <pfred1> we tried it in the 70s and it just didn't go over so well
[23:15:28] <pfred1> no one wanted to buy gasoline by the liter
[23:16:19] <L84Supper> I've been here for 50 years and I use it all the time, are you from the hills by chance? :)
[23:16:38] <pfred1> here where?
[23:16:52] <L84Supper> uhmerica
[23:16:52] <Connor> pfred1 you would be surprised at how much our non-metric stuff has influenced stuff though..
[23:16:53] <pfred1> you show me where we post speed limits in anything other than miles per hour
[23:16:58] <L84Supper> uhmerika
[23:17:18] <pfred1> or sell gasoline in anything other ghan gallons
[23:17:21] <L84Supper> merika for short
[23:17:55] <pfred1> the only thing they use metric for in this coutnry is selling dope
[23:18:06] <pfred1> oh and soda
[23:18:11] <Connor> pfred1 I didn't say that.. Lots of metric stuff is really just inch converted because it's so wide spread..
[23:18:41] <L84Supper> pfred1: don't you have any contact with the rest of the world?
[23:19:02] <pfred1> I went to Canada once
[23:19:03] <Connor> pfred1 and several places have the Speed limit in both..
[23:19:09] <L84Supper> lol
[23:19:31] <pfred1> they had funny sped limit signs
[23:19:40] <Jymmm> pfredx1: you forgot tires
[23:19:52] <pfred1> but no the USA rocks so why would i want to go anywhere else i mean I'm alreayd here
[23:20:28] <pfred1> if i want to visit someplace exotic I'll go to a 7 11
[23:20:34] <L84Supper> plus they got commies out there
[23:20:36] <pfred1> no one in there speaks english
[23:22:04] <pfred1> the rest of the world really has no idea how little we care about them do they?
[23:22:23] <L84Supper> actually they do
[23:23:42] <pfred1> well we've always been isolationist
[23:23:45] <L84Supper> Alfred E. Neuman and the Penguin made them painfully aware
[23:24:04] <pfred1> foreign entanglements and all of that
