01:34 AM Deejay: moin
02:46 AM Sabotend_ is now known as Sabotender
04:40 AM jthornton: morning
04:40 AM XXCoder: morning
05:25 AM XXCoder: jthornton: wow! west washington may get 4 to 8 inches
05:25 AM XXCoder: thats very rare
05:25 AM XXCoder: last time it happened I haven't moved to tacoma, which is over 6 years ago
05:26 AM XXCoder: and it was some number of years before I moved
05:26 AM jthornton: snow?
05:27 AM Tom_itx: morning
05:27 AM XXCoder: oops yeah snow
05:28 AM Tom_itx: 14�F, Hi 22, Lo 8
05:28 AM XXCoder: in spring and fall it rains so much i forget what color roads are when dry.
05:28 AM Tom_itx: icy here
05:29 AM XXCoder: not much ice here, roads is mostly dry due to all the sun during week.
05:29 AM XXCoder: but snow is still around so far.
05:29 AM Tom_itx: schools all closed
07:17 AM MacGalempsy: mornin
07:17 AM XXCoder: yo
07:17 AM MacGalempsy: what shakin big daddy?
07:18 AM XXCoder: not much. just bought scabblenauts for wiiu because I like puzzle games so far lol
07:18 AM XXCoder: captain toad is fanastuc
07:18 AM MacGalempsy: https://flic.kr/p/2dwFxAw
07:19 AM XXCoder: not loading
07:19 AM MacGalempsy: cool. sounds fun.a work
07:19 AM XXCoder: finally
07:19 AM MacGalempsy: at work...
07:19 AM XXCoder: looks reasonable print. whats you making tho
07:20 AM MacGalempsy: that is a fan duct.
07:20 AM MacGalempsy: the only thing this new printer requires was assembly and bed leveling
07:21 AM MacGalempsy: everything else was good to go, firmware, cura, etc... quite amazing actually
07:22 AM MacGalempsy: that thing is a petsfang from thingiverse
07:22 AM XXCoder: not bad
07:23 AM MacGalempsy: for $230, it cannot be beat
07:25 AM MacGalempsy: ehat have you been making lately?
07:25 AM XXCoder: not a lot unfortunately lol
07:25 AM MacGalempsy: sometimes that is good
07:32 AM jthornton: which printer did you get?
07:32 AM MacGalempsy: ender pro 3
07:33 AM MacGalempsy: the only upgrade I would like to so is the autoleveler
07:33 AM jthornton: this one? https://www.amazon.com/Comgrow-Creality-Printer-Upgrade-Certified/dp/B07GYRQVYV
07:35 AM jthornton: you run it from a pc?
07:40 AM MacGalempsy: sd card
07:40 AM MacGalempsy: I got it from the creality website
07:40 AM MacGalempsy: it can run from a pc, but haven't done it yet
07:41 AM XXCoder: pc just adds more chance of failure
07:47 AM XXCoder: offf to bed laters
07:57 AM avernos: what are the G54-59 workspaces for? different classes for parsing dimensions? why they store offsets ? help?
08:02 AM Tom_itx: they are for work offsets
08:02 AM JT-Shop: avernos: http://linuxcnc.org/docs/2.7/html/user/user-concepts.html
08:05 AM Tom_itx: for example if you wanted to run multiple positions for a part
08:07 AM avernos: thanks! multiple positions for a part? im thinking on 2D laser engrave.. i guess multiple positions in case you lift and turn the stock upside down or something like that?
08:17 AM Tom_itx: probably not used much on a laser
08:20 AM JT-Shop: pcw_home: do you have a 7i92 bit file for a cnc4pc cllg and c10?
08:52 AM MacGalempsy: ...was chatting and apparently nothing was posting...
08:53 AM JT-Shop: I lost internet lol
09:15 AM CNC_Brian: Am I safe using 2.8 to run my PM25 Mill? Want to have a play with QtPyVCP
09:18 AM gloops: my router has run on 2.8 for about a year with no issues, had no updates or anything though since i set it up
09:21 AM jthornton: yea I've been running master for some time now
09:22 AM jthornton: CNC_Brian: did you see the basic vcp tutorial?
09:25 AM CNC_Brian: Yes, Im trying to install using the instructions you posted me at yesterday
09:25 AM CNC_Brian: Just installing Debian 9
09:26 AM CNC_Brian: Then LinuxCNC 2.8
09:26 AM CNC_Brian: Installing to a spare disk so I can try it om my PM25
09:27 AM CNC_Brian: Just do basic 2.5 Milling
09:33 AM jthornton: are you using my install instructions?
09:33 AM CNC_Brian: Yes
09:33 AM CNC_Brian: https://forum.linuxcnc.org/9-installing-linuxcnc/34892-installing-linuxcnc-on-debian-9
09:33 AM jthornton: cool, let me know if anything is not easy
09:33 AM jthornton: http://gnipsel.com/linuxcnc/uspace/
09:34 AM jthornton: use the above link
09:34 AM CNC_Brian: Yep that's the next stage after getting Deb 9 up and running
09:37 AM pcw_home: JT-Shop: No but I should be able to copy-pasta one together
09:38 AM jthornton: ok thanks just let me know what header is for what so I can make the correct cables for him
09:38 AM jthornton: mmmm pasta
09:42 AM macgalempsy: JT are you still making the spyder accessories?
09:44 AM jthornton: aye
09:45 AM pcw_home: jthornton: the C10 is new to me, it looks like a generic buffer card, do you know what I/O is needed?
09:47 AM macgalempsy: the other day, I saw a guy making custom Roxor parts and thought about that
09:47 AM macgalempsy: they are mostly making large panels, and such
09:47 AM pcw_home: if its just for GPIO the C11GX2 would work, but if the customer wants more stepgens or maybe encoders I would have to know
09:48 AM JT-Shop: ok let me check
10:20 AM JT-Shop: pcw_home: ok he just needs I/O on the C10
11:07 AM CNC_Brian: Guy's, got a virtual machine running with 2.8 and QtPtVCP. Running probe basic UI, but I can't seem to do much with it
11:08 AM CNC_Brian: Is this a sim, I don't have a Parallel port card installed or anything
11:08 AM rmu: CNC_Brian: what do you want to do
11:08 AM CNC_Brian: I would like to use it to drive my PM25
11:09 AM rmu: virtual machine implies you cant run hardware
11:09 AM CNC_Brian: Im just having a dry run of the install
11:10 AM rmu: "I can't seem to do much with it" sounded like a problem. sorry.
11:16 AM CNC_Brian: I will add a virtual parallel port. I think that is the problem.
11:16 AM CNC_Brian: Was expecting to power on and home then run the example tool path
11:18 AM Loetmichel: Gnhihi. i Like my Opel Omega car... but if i want to keep it i should buy a new set of rubbers soon... just exited a roundabout at 60kph... all 4 wheels lost grip and i drifted out a lane in the corner. the driver in the car behind me nearly shat himself, judging by the abount he jerked on his steering wheel. ;)
11:22 AM JT-Shop: CNC_Brian: my basic vcp tutorial is a sim
11:23 AM JT-Shop: https://github.com/jethornton/vcp1
11:24 AM JT-Shop: https://github.com/kcjengr/vcp-template
11:24 AM JT-Shop: https://qtpyvcp.kcjengr.com/tutorials/basic_vcp.html
11:33 AM CNC_Brian: So I have used step config to setup a basic 3 axil mill and set qtpyvcp Probe Basic as the UI
11:39 AM JT-Shop: that should work
11:51 AM CNC_Brian: Think it is but 3dChips federate is something crazy like 450000mm/min
11:51 AM CNC_Brian: Think its just finishing quick
12:04 PM Jymmm: Man, I freeze my feet off wearing rubber boots in the snow
12:04 PM fragalot: should've worn uggs
12:05 PM Jymmm: https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQM2vPCiOrkLHWhet6794VgLSFjC0Rmn39NsQdQFUmuasEfiwtb
12:05 PM JT-Shop: should have worn mukluks
12:05 PM fragalot: molusks?
12:06 PM JT-Shop: no mukluk is a boot make from seal skin
12:06 PM fragalot: I see
12:06 PM Jymmm: do winter socks really work?
12:06 PM JT-Shop: they are very warm
12:07 PM JT-Shop: oversize boots and thick wool socks
12:07 PM rmu: CNC_Brian: in virtual machine, use a sim config
12:08 PM Jymmm: JT-Shop: I usually wear rubber boots, but wasn't sure of wool socks really help or not
12:08 PM JT-Shop: they wick the moisture out, my snow boots had felt liners
12:09 PM Jymmm: I just have those black and rust orange rubber boots
12:16 PM ziper: CaptHindsight, is it ok to use spray adhesive to stack up dry laminate in an infusion mold?
12:17 PM ziper: I found a couple products that say that are compatible with polyester etc, but no mention of epoxy
12:17 PM ziper: or is that because epoxy will bond with anything, so it doesn't matter what adhesive you use?
12:19 PM fragalot: epoxy does not bond with anything
12:21 PM FinboySlick: Jymmm: Since I discovered 'Darntough', I wear wool socks all year round. First time I've heard of a lifetime guarantee on socks.
12:23 PM CNC_Brian: Not sure what I did but its working.
12:26 PM ziper: anything*
12:29 PM fragalot: everything*
12:36 PM gloops: the expoxy is very sticky when its poured, doesnt mean other things stick to it when its dry
12:36 PM gloops: epoxy
12:42 PM ziper: right, but the spray adhesive is applied before the epoxy infusion
12:42 PM gloops: oh, so whats the spray sticking?
12:43 PM CaptHindsight: depends on the adhesive used
12:44 PM CaptHindsight: the epoxy will encapsulate everything but....
12:44 PM FinboySlick: If you drill and tap holes, the epoxy will 'adhere' to them ;)
12:45 PM CaptHindsight: how much adhesive and type will effect how well the epoxy bonds to it
12:45 PM CaptHindsight: if you want it to polymerize with the adhesive you can make that happen
12:47 PM CaptHindsight: adhesive bonds vs chemical bonds also needs to be clarified
12:47 PM fragalot: should be fun if your adhesive just happens to contain something that prevents the epoxy from curing :D
12:47 PM gloops: that reminds me i need to get some high temp pouring silicone
12:47 PM gloops: gonna try casting tin/pewter in silicone molds
12:47 PM ziper: just enough to get the carbon to adhere to the part being repaired
12:47 PM CaptHindsight: fragalot: yeah gooey mess
12:48 PM gloops: ziper so carbon matting
12:49 PM ziper: I did a repair and in a couple spots the carbon had shifted while putting down the peel ply, vacuum bag, etc
12:49 PM gloops: seems dodgy to me trying to pour the epoxy on dry matting, the mat needs wetting and rolling
12:49 PM Jymmm: FinboySlick: Thanks, I'll check them out. I've never worn wool anything before.
12:49 PM CaptHindsight: if you use a urethane adhesive with a catalyst and coat with epoxy the two systems will crosslink
12:50 PM CaptHindsight: but now you're dealing with isocyanates, not nice stuff
12:50 PM ziper: gloops, https://youtu.be/VodfQcrXpxc?t=707
12:51 PM gloops: ahh vaccum bagging
12:51 PM Jymmm: FinboySlick: WTH is a "tactical sock" ?! lol
12:51 PM CaptHindsight: if you sparingly use a spray acrylic adhesive the epoxy won't crosslink with it but will still coat everything
12:52 PM FinboySlick: Jymmm: They didn't have those when I last shopped there. But they're definitely good 'murica-made stuff.
12:53 PM ziper: oh, it looks like 3m 71 is exactly what I want
12:53 PM gloops: so youre making progress with the drone parts ziper?
12:53 PM CaptHindsight: ziper: yeah I have 77 here as well
12:53 PM ziper: no drone parts, only boat parts
12:53 PM ziper: maybe a fixed wing in the future
12:54 PM ziper: but rotary wing does not interest me
12:54 PM gloops: must have been someone else looing at drone bodies
12:54 PM ziper: we did talk about it before
12:56 PM ziper: CaptHindsight, how do you keep the edges from fraying when you are doing an aesthetically pleasing top layer?
12:58 PM CaptHindsight: gel coat mold
12:58 PM CaptHindsight: or sand and polish
12:59 PM gloops: id leave the thickness of the panel, say 4mm as part of the mold, if you see what what i mean, then the edge is molded, not cut/sanded
01:00 PM gloops: dont just cut the panel where the mold ends
01:01 PM CaptHindsight: if the fiber doesn't reach the surface of the epoxy then it won't fray
01:11 PM CaptHindsight: ziper: just FYI, you typically want to recoat epoxy within 24 hours, even less if it sets very quickly
01:20 PM * SpeedEvil wonders if you could improve bonding by heating old epoxy to the glass transision temperature. (if it has not already been) (probably a bad idea)
01:24 PM gloops: i wonder how long a life the molds have with this high temp pouring silicone
01:25 PM CaptHindsight: SpeedEvil: won't break the bonds
01:25 PM fragalot: gloops: maybe one
01:25 PM gloops: its only RV silicone with some powder filler to increase heat resistance so far as i can see
01:25 PM fragalot: gloops: maybe more
01:25 PM fragalot: gloops: maybe less
01:25 PM fragalot: :)
01:25 PM gloops: fragalot one cast is no good its £50 a kilo
01:26 PM gloops: i think it might be ok they use it for baking tins they last long enough
01:26 PM CaptHindsight: SpeedEvil: if you were printing on the epoxy it might help, plasma treating helps slightly
01:27 PM CaptHindsight: plasma, corona, flame treating to up the surface energy
01:28 PM gloops: what im going to do is carve out some gothic letters in wood, polish them up, then take some silicone molds and pour tin into the, try them as inlay on wooden signs etc
01:41 PM CaptHindsight: we need individually programmable CF spinning spiders that can weave in 3D
01:41 PM CaptHindsight: or silk
01:41 PM fragalot: both
01:41 PM fragalot: silk for flexibility, CF for the stiffer parts
01:42 PM Jymmm: CF???
01:42 PM fragalot: carbon fiber
01:42 PM Jymmm: eh
01:42 PM fragalot: it'd be idiotic to have compactFlash spiders
01:42 PM Jymmm: spider silk is 10x strong than stell
01:42 PM CaptHindsight: or cystic fibrosis
01:42 PM Jymmm: steel*
01:42 PM Jymmm: or cold fusion
01:43 PM gloops: in the box thinking
01:43 PM gloops: in the future material will be intelligent and programmable
01:43 PM Tom_itx: transformers
01:44 PM gloops: carbon nanobytes will arrange themselves in the required form at strengths harder than diamonds
01:44 PM CaptHindsight: yes yes with the inherent limitations
01:44 PM CaptHindsight: if they deposit nano poop then yes
01:45 PM CaptHindsight: the carbon composite nanobytes would have to shed them selves of the non carbon parts
01:45 PM fragalot: CaptHindsight: what if you inhale said nano poop?
01:45 PM gloops: biological organisms manage ok
01:46 PM CaptHindsight: depends www.depend.com
01:46 PM CaptHindsight: gloops you're mostly water
01:47 PM fragalot: CaptHindsight: I thought he was mostly hot air?
01:47 PM fragalot: :3
01:47 PM gloops: filled with water yes
01:48 PM CaptHindsight: too easy
01:48 PM gloops: car engines are filled with water, you need internal transport networks
01:49 PM fragalot: there was no wanted water in my trabants car engine
01:50 PM CaptHindsight: nano self assembly might be used to guide carbon atoms into position
01:50 PM CaptHindsight: but then they would get out of the way
01:52 PM CaptHindsight: https://phys.org/news/2018-06-breakthrough-dna-based-robots.html
01:53 PM FinboySlick: They invented thousands of years ago with slavery.
01:53 PM gloops: if a shoulder joint was dry metal it would wear out quickly
01:53 PM gloops: we can get the heat out, self lubricate etc, its a very good design model
01:54 PM fragalot: isn't molybdenum a metal?
01:54 PM gloops: its not dry though
01:54 PM fragalot: isn't it?
01:54 PM gloops: not in a shoulder joint
01:55 PM CaptHindsight: https://www.nature.com/articles/s41467-018-03601-5
01:55 PM CaptHindsight: Real-time magnetic actuation of DNA nanodevices via modular integration with stiff micro-levers
01:57 PM fragalot: CaptHindsight: loving those words
01:58 PM gloops: species 8472 had bio-ships
01:58 PM CaptHindsight: we could make a nano mill or lathe that cuts with tools
01:59 PM CaptHindsight: somebody fund me to make them please
02:00 PM fragalot: I've got a few atoms spare
02:00 PM CaptHindsight: nano funding
02:20 PM CaptHindsight: https://sci-hub.tw/10.1016/j.cirp.2006.10.002 Micro and Nano Machining by Electro-Physical and Chemical Processes
02:23 PM fragalot: micro USM is one I hadnt heard of
02:24 PM gloops: excellent, all we need now is a quantum computer
02:27 PM gloops: humans main problem is that theyre the smartest thing around, we need slaves smarter than us so we dont have to think
02:27 PM CaptHindsight: was van der Waals Dutch or did he drive a van?
02:27 PM fragalot: CaptHindsight: likely both
02:27 PM gloops: guessing he was the son of Waals
02:28 PM fragalot: but coming from wallonia
02:28 PM * fragalot spits
02:28 PM CaptHindsight: https://onrobot.com/products/gecko-gripper/
02:29 PM CaptHindsight: https://www.youtube.com/watch?v=MXO_PqSvtTU
02:34 PM fragalot: black magic
02:34 PM fragalot: CaptHindsight: I went to another expo yesterday on new innovations in industry
02:34 PM fragalot: obviously there is a lot of talk again about big data analysis, AI and so on
02:35 PM fragalot: so one example was saving compressed air on looms to shoot the thread across, how they used big data to really nail down on how little air usage they could get by with, without compromising reliability
02:35 PM fragalot: which was kinda neat, as the machine was already thought to be quite efficient
02:36 PM fragalot: the very next topic by the same speaker was "and this is how we developed pathing technology for aerial drones for warehousing"
02:36 PM fragalot: whoosh. byebye energy savings mentioned earlier :D
02:37 PM fragalot: (that said, it was pretty neat)
02:37 PM gregcnc: if you can afford to pay for it, you can use all the energy you want....
02:37 PM gregcnc: I used little this morning
02:37 PM gregcnc: there was no power until ~1pm
02:39 PM CaptHindsight: ice storm knock you out?
02:39 PM CaptHindsight: looked like an alien world
02:40 PM gregcnc: yeah. somethign woke me about 4am. then i heard a loud noise, maybe something falling
02:40 PM gregcnc: not long after the sky flashed blue and it was dark
02:40 PM fragalot: can't have overhead lines because they freeze & shit breaks
02:41 PM fragalot: can't have underground lines because they freeze & shit breaks
02:41 PM fragalot: sad days. :P
02:42 PM CaptHindsight: why wireless power is best
02:42 PM CaptHindsight: energy rays from towers direct to you!
02:42 PM gregcnc: then i got nervous about the basement and ran over to horrorfright and bought a generator. by the time I got home power was on, if I waited maybe 3 minutes...
02:43 PM gregcnc: nikola tesla
02:43 PM fragalot: gregcnc: ha :D
02:43 PM CaptHindsight: gregcnc: well you never know how long to wait
02:43 PM CaptHindsight: but now you are ready
02:44 PM fragalot: that is when you find out you forgot the engine oil
02:44 PM gregcnc: I'll read the reviews, if it doesn't suck, I'll keep it
02:44 PM gregcnc: i have oil
02:44 PM gregcnc: and canned gas
02:44 PM CaptHindsight: we have underground power, never goes out
02:46 PM gloops: we have expensive power
02:48 PM CaptHindsight: last building also had underground power but the boring company still managed to knock it out
02:48 PM CaptHindsight: same for internet, the boring cos always cut through our lines
03:35 PM Tom_itx: gregcnc you'll have it for the next round
03:35 PM gregcnc: was thinking about getting one last spring
03:36 PM Tom_itx: i wore one out and traded for a new one. since i haven't used it that much but i keep it full of fresh fuel and ready
03:39 PM Tom_itx: old one the carb started surging and a cleaning didn't fix it
03:40 PM * JT-Shop has a two cylinder deutz diesel 3 phase generator for some reason
03:40 PM Tom_itx: my bud pulled a 15kw from a grocery store
03:41 PM Tom_itx: wired it with a mains switch etc
03:42 PM JT-Shop: I finally got the mains sorted out so I can turn off a breaker and isolate the incoming power and the rest can be on the generator
03:42 PM Tom_itx: no main cutoff switch?
03:43 PM Tom_itx: err mains breaker
03:44 PM JT-Shop: when I built the house I ran power from the meter to the house panel which has a main breaker then I build the garage and added a breaker outside for that right off the meter so at that point no way to have them both on with the power isolated except to pull the meter
03:45 PM JT-Shop: now the incoming power goes to the new outside box through a main breaker and that box feeds the house, garage, machine shop and new shop
03:46 PM JT-Shop: oh and the chicken coop
03:46 PM CaptHindsight: JT-Shop: did you find this months bandwidth hog?
03:46 PM Tom_itx: you should put the coop on a separate meter so you can charge them keep
03:47 PM CaptHindsight: the power co requires SS# from each new account
03:47 PM JT-Shop: no, some web page I left up I guess, I'm only using 0.1GB a day now lol
03:48 PM JT-Shop: yea they are slacking a bit paying rent now with some molting and not laying
03:48 PM CaptHindsight: if the chicken incorporate then they can use a EIN
03:48 PM JT-Shop: lol
03:58 PM Papagno: Hi one question . The esternal offset fuction only with axis interface. i have test it with tk interface and non fuction. because
04:05 PM Deejay: gn8
04:26 PM jthornton: wow he didn't stay very long lol
04:34 PM Tom_itx: i know i'm gettin old and slow by my god...
04:35 PM Tom_itx: but*
04:47 PM jthornton: lost your train of thought?
04:48 PM Tom_itx: he wasn't real clear with his question either
04:49 PM Tom_itx: must be something new to 2.8
04:50 PM jthornton: I'm guessing he tried to use external offsets with the TkLinuxCNC GUI and it's amazing it is still here
04:50 PM jthornton: yea it's in master only
04:55 PM Tom_itx: what is their intended purpose?
05:01 PM jthornton: external offsets is so you can have something like torch height control that is not a kludge
05:01 PM jthornton: but I never could understand how it worked as it's so complicated
05:02 PM Tom_itx: i thought it might have something to do with plasma cutters
05:02 PM jthornton: you can use it with other stuff I guess
05:09 PM Tom_itx: i suppose but i can't see the need
05:42 PM Tom_itx: jthornton, you been running 2.8 on your mill?
05:43 PM jthornton: on the BP yes
05:44 PM jthornton: using QtPyVCP GUI I made
05:44 PM Tom_itx: is it difficult to tie the gui to the pins?
05:45 PM Tom_itx: QtPyVCP is something new to me
05:49 PM jthornton: what pins?
05:49 PM jthornton: is it difficult no
05:49 PM Tom_itx: i guess i'm not clear on how the GUI ties to lcnc
05:50 PM Tom_itx: same widgets we put on the right pannel in axis?
05:53 PM jthornton: no, the widgets are not the same as a pyVCP widget
05:54 PM jthornton: you just have to set the display to qtpyvcp and vcp to your vcpname in the ini
05:54 PM Tom_itx: i see that under 'stand alone' in the docs now...
05:56 PM jthornton: what's that?
05:57 PM Tom_itx: how to roll your own GUI
05:57 PM jthornton: https://qtpyvcp.kcjengr.com/tutorials/basic_vcp.html
05:57 PM jthornton: that's my tutorial
05:57 PM Tom_itx: saw that the other day
05:58 PM jthornton: which docs did you see stand alone in?
05:58 PM Tom_itx: master
05:59 PM jthornton: what section?
05:59 PM Tom_itx: well it's in 2.7 too but probably not the same
05:59 PM Tom_itx: http://linuxcnc.org/docs/devel/html/gui/pyvcp.html#_stand_alone
05:59 PM jthornton: oh that's for pyvcp not qtpyvcp
06:00 PM Tom_itx: ahh ok
06:00 PM jthornton: pyvcp and qtpyvcp and qtvcp are all different
06:01 PM Tom_itx: great
06:02 PM jthornton: qtpyvcp is designed to be more flexible than qtvcp
06:02 PM jthornton: QtPyVCP is a Qt and Python based framework for building virtual control panels for the LinuxCNC machine control.
06:03 PM hazzy-m: Tom_itx: we carefully chose the names to be as confusing as possible, lol
06:03 PM jthornton: lol
06:04 PM Tom_itx: thank you :D
09:44 PM tiwake: can SLS type rapid prototyping machines be used with aluminum?
09:47 PM Tom_itx: https://www.protolabs.com/services/3d-printing/direct-metal-laser-sintering/
09:47 PM Tom_itx: is that the same?
09:48 PM Tom_itx: if so then yes
09:48 PM tiwake: yeah, thats the process
09:48 PM Tom_itx: Our DMLS selection includes aluminum, cobalt chrome, Inconel, stainless steel, and titanium.
09:52 PM tiwake: hmm
09:52 PM tiwake: Tom_itx: how much does the titanium cost per lb?
09:52 PM tiwake: in powder form
09:52 PM Tom_itx: i'm not sure
09:52 PM Tom_itx: i know the process is expensive
09:52 PM tiwake: why?
09:52 PM tiwake: the machine is expensive I know
09:53 PM tiwake: but I can't imagine it being more expensive than anything else really
09:53 PM Tom_itx: the vo-tech has an array of i think 12 or 15 inert gas bottles hooked to theirs
09:53 PM Tom_itx: they go thru alot of gas
09:54 PM Tom_itx: i don't know the cost of material
09:54 PM tiwake: hmm
09:57 PM Tom_itx: https://www.americanelements.com/titanium-powder-7440-32-6
09:57 PM Tom_itx: ask for a quote :)
10:17 PM Tom_itx: tiwake, http://pencerw.com/feed/2014/1/6/dmls-pricing
10:18 PM Tom_itx: from $987 to $2377 for one bicycle seat holder
10:19 PM Tom_itx: http://pencerw.com/topper
10:19 PM Tom_itx: shown there
10:22 PM tiwake: hmm
10:23 PM tiwake: Tom_itx: I'd be building my own SLS type machine, was wondering what the cost is for raw materials
10:23 PM Tom_itx: yeah, i don't know about that
10:23 PM tiwake: isnt there a rapid prototyping machine convention?
10:24 PM Tom_itx: i know at least on the one at the vo-tech they have to fill the chamber no matter how big the part is
10:24 PM tiwake: yeah
10:24 PM Tom_itx: one missed layer or bump etc and the part is scrap
10:30 PM Tom_itx: http://tom-itx.no-ip.biz:81/~webpage/cnc/temp/prints/Ti_print1.jpg
10:30 PM Tom_itx: some of the stuff they did with Ti
10:31 PM Tom_itx: http://tom-itx.no-ip.biz:81/~webpage/cnc/temp/prints/Ti_print2.jpg
10:31 PM Tom_itx: all one print
10:35 PM tiwake: I'll have to talk to some people
10:38 PM Tom_itx: be interesting what you find
10:41 PM Tom_itx is now known as Tom_L
