[05:45:05] <archivist> anyone in scotland want some iron http://www.ebay.co.uk/itm/Mazak-CNC-Mill-/171423778653
[06:20:54] <SpeedEvil> In principle, I could, if I maxed out my credit cards, and spent all my savings for heating for the winter
[06:21:31] <SpeedEvil> I think - on balance - I _probably_ would be better served by something rather smaller.
[06:29:46] <archivist> wear more layers, then you dont need heating
[06:31:14] <Lathe_newbie> hi there
[06:31:35] <Lathe_newbie> anyone here experience with linear delta robots like rostock 3d printers
[06:31:36] <Lathe_newbie> ?
[06:32:00] <archivist> ask the real question
[06:33:14] <Lathe_newbie> how to implement the kinematics for something like this?
[06:33:19] <Lathe_newbie> are there any examples?
[06:34:22] <archivist> yes I do believe, have you searched the samples and sim directories
[06:46:02] <Lathe_newbie> im looking for code for something like this https://www.youtube.com/watch?v=FgnxBaFFDi8
[06:49:24] <archivist> he has a site somewhere I think
[06:49:51] <Lathe_newbie> i didnt found it
[06:59:22] <archivist> look at description on https://www.youtube.com/watch?v=5MOSnFSx8JQ&list=UUsyQLjKgnIRvhlW7nLwyAqQ
[07:03:25] <Lathe_newbie> for this type i have found the kinematics
[07:03:34] <Lathe_newbie> but i need for a linear tripod
[07:05:30] <archivist> that points to his site, have you then searched his site
[07:08:44] <archivist> and then I searched his nick and found http://blog.machinekit.io/2013/07/linear-delta-kinematics.html
[07:33:49] <Lathe_newbie> archivist: the source file is not available
[07:34:48] <archivist> and that page shows jeplers repo
[07:38:10] <Lathe_newbie> but this tree is empty
[07:42:13] <Loetmichel> harhar... $me had just found 2 orginal shrink wrapped packs of cigarettes in his desk. I switched to vaping last october... I wonder: should i bring the packs to the co-worker as a gift or are they already dried out?
[07:44:25] <Lathe_newbie> have found them
[08:34:40] <DaViruz> Loetmichel: smoke one and see :)
[08:50:42] <skunkworks> Lathe_newbie: how is the lathe working?
[09:00:15] <Jymmm> Plastic-Dip painted car https://www.youtube.com/watch?v=zROKTpH1U1Y
[10:08:28] <Lathe_newbie> skunkworks: it is up and running
[11:43:32] <CaptHindsight> Jymmm: https://www.youtube.com/watch?v=vvkq-qyY9aY its limitations
[11:46:47] <MrSunshine> i dont understand downcutting bits, the chip evacuation in my mind would be a nightmare ?
[11:47:42] <archivist> you dont cut in a blind hole
[11:48:09] <Tom_itx> some bits have thru bit coolant too
[11:48:14] <IchGuckLive> hi all B)
[11:48:27] <MrSunshine> this is woodworking bits =)
[11:48:54] <Tom_itx> well that's no good then
[11:49:03] <archivist> it forces the sheet downward
[11:49:34] <archivist> you dont want to lift a suction held sheet
[11:51:18] <XXCoder> hey
[11:51:57] <XXCoder> archivist: if its making a blind hole where does wood swarf go
[11:52:19] <archivist> it would not be in a blind hole
[11:53:16] <XXCoder> So it can't be used that way. intersting
[11:55:31] <archivist> in some situations it is better for swarf to go forward, like a machine tap, but there is a version of machine tap to bring the swarf out the rear, it is a choice
[11:57:35] <Jymmm> CaptHindsight: Thanks, it's nice seeing the variety there.
[12:00:21] <XXCoder> heh all my youtubeads is about cnc stuff nowdays
[12:00:48] <XXCoder> youtube ads
[12:00:56] <Tom_itx> watch more pron
[12:01:10] <XXCoder> lol
[12:08:56] <IchGuckLive> XXCoder: you are the upcomming master of desaster
[12:16:01] <IchGuckLive> Tom_itx: what is pron
[12:25:31] <IchGuckLive> hi recon_lap1
[12:25:31] <Jymmm> IchGuckLive: This is CNC pron... https://www.youtube.com/watch?v=A_qHR_H_2cg
[12:26:37] <recon_lap1> hello IchGuckLive.
[12:26:48] <IchGuckLive> yeah it is deckel Maho Gildemeister DMG alway got good show parts
[12:27:07] <IchGuckLive> recon_lap1: lab is always not a good choice
[12:27:42] <recon_lap1> IchGuckLive: lab?
[12:28:11] <IchGuckLive> nootbook
[12:28:37] <IchGuckLive> recon_lap1: where i the world are you im in germany
[12:30:07] <recon_lap1> IchGuckLive: In Ireland :)
[12:30:20] <IchGuckLive> ah in the europ time zone
[12:30:33] <IchGuckLive> so you already got a runnig cnc
[12:32:18] <recon_lap1> No, Just a 3d printer. Thinking of building a small CNC router. just lurking here to see what I can learn.
[12:32:43] <recon_lap1> and 1/2 way through building a small PCB mill
[12:32:48] <IchGuckLive> 3d printer ready made or home made
[12:33:18] <recon_lap1> I3, parts bough online , mostly off ebay
[12:33:23] <IchGuckLive> recon_lap1: pcb mill only to give you a idee http://foengarage.de/cnc4.jpg
[12:34:01] <IchGuckLive> http://foengarage.de/pcb.jpg milled fr4
[12:35:56] <recon_lap1> lot of expensive looking parts on those PCB mills
[12:36:19] <IchGuckLive> no less then 300EU
[12:36:34] <IchGuckLive> all stuff including proxxon
[12:36:47] <CaptHindsight> recon_lap1: prices depend on your ebay-foo and timing
[12:36:56] <tjtr33> foen = barber?
[12:37:03] <IchGuckLive> the steppers are out of epson laserprinters
[12:37:14] <IchGuckLive> 1 euro eatch
[12:37:33] <IchGuckLive> the board is a tb6560 from our user here at 15usd
[12:37:56] <IchGuckLive> the axis spindles are TR16x4
[12:38:15] <IchGuckLive> for better smoother drining there is a 1:1 timingbelt system
[12:38:33] <IchGuckLive> only LMUU12 in use 20pcs less then 50USD
[12:38:48] <IchGuckLive> from china
[12:39:15] <IchGuckLive> the master 24V 5V from meanwell and a C10 BOB
[12:39:54] <IchGuckLive> some hard pins C54 12mm 2m in toatal and 1m of 30sqare alu
[12:40:31] <IchGuckLive> tj yea
[12:40:57] <recon_lap1> IchGuckLive: basically a lot of stuff I don't have :) but nice that you got it done so cheap :)
[12:41:05] <tjtr33> haha i went to front page, looks like B-52's! nice
[12:41:55] <recon_lap1> IchGuckLive: but I'm going with the start small and working up to better, bit by bit.
[12:41:57] <tjtr33> http://www.youtube.com/watch?v=9SOryJvTAGs
[12:42:06] <IchGuckLive> tjtr33: hit salon on front page
[12:42:13] <tjtr33> bt very nice mill IchGuckLive
[12:43:06] <IchGuckLive> tjtr33: as you know the mill and the lathe hat to fit a standard universety education table
[12:43:15] <IchGuckLive> so no way on sizing
[12:44:07] <recon_lap1> I started on a Cyclone PCB mill reprap build, but think I'll try one of these next http://www.diyouware.com/front
[12:45:11] <IchGuckLive> this realy low level
[12:45:52] <IchGuckLive> home made electronic trivers
[12:46:24] <IchGuckLive> with a blueray laser diod
[12:46:33] <IchGuckLive> on a lm317 driver
[12:47:16] <Jymmm> voltage regualtor?
[12:47:38] <IchGuckLive> yes as a constand Amp source
[12:47:41] <Jymmm> am
[12:47:43] <Jymmm> ah
[12:48:07] <IchGuckLive> based on a 1.25V standard out
[12:48:23] <IchGuckLive> good for red DVD bad on Blue
[12:48:40] <Jymmm> Yeah, I've seen the datasheet with the CC example =)
[12:48:46] <IchGuckLive> it workes but not efficant as you see speed below 300mm/min
[12:49:02] <IchGuckLive> that makes like my DVD on wood in the vids i got on youtube
[12:49:10] <IchGuckLive> with 10USD costs
[12:49:18] <Jymmm> =)
[12:49:57] <IchGuckLive> im off BYE
[13:41:31] <skunkworks> wow - I don't see anything in that video that linuxcnc couldn'
[13:41:41] <skunkworks> t do
[13:47:41] <archivist> skunkworks, except the tool table size :(
[13:48:32] <archivist> can we switch kins on the fly ?
[13:49:05] <skunkworks> smop!
[13:49:06] <archivist> or were they cheating by doing it in the cam
[13:49:14] <skunkworks> that could be..
[13:50:26] <archivist> they change from lathe to milling to hobbing with ease
[13:51:16] <archivist> oh and eccentric turning
[13:53:01] <skunkworks> sure - all doable - maybe not as smooth..
[13:54:41] <archivist> DMG do throw chips about at shows
[14:21:31] <skunkworks> I have started to get this same thing using chrome on 14.04
[14:21:32] <skunkworks> http://www.bleepingcomputer.com/forums/t/544587/outdated-java-plugin-detected-with-linux-mint-and-chrome/\
[14:29:10] <tjtr33> and often you'd need some other java, like open ibm or oracle (java, write once, and ... try again )
[14:29:55] <tjtr33> some nice apps, heck theres a java front end for linuxcnc by matt shaffer
[14:30:06] <tjtr33> is/was
[14:34:15] <MrSunshine> http://www.pinterest.com/pin/492862752940915857/
[14:37:59] <CaptHindsight> that's handy, I often get confused between screws and washers :p
[14:38:53] <MrSunshine> :P
[14:41:19] <recon_lap1> skunkworks: it might be the site that is hacked and not your computer
[15:16:37] <anarchos> Can anyone tell me the terminology for my situation? Using HSMExpress w/ SolidWorks, it's generating GCode that "plunges" all the way into the work piece then cuts like 1" of material at a time
[15:16:52] <anarchos> i need it to do like 2mm at a time, in multiple passes
[15:17:15] <anarchos> that would be called cut depth, no?
[16:05:50] <Deejay> gn8
[16:21:17] <jdh> yes
[19:06:12] <android14141480> Hello i need a channel for plasma cutter who know it
[19:19:51] <android14141480> J
[19:20:38] <android14141480> I need a channel where talk about plasma cutter this channel is here ?
[19:23:59] <BellinganRoy> It depend's on the subject, if is the plasma cutting itself then *this is not the channel*
[19:26:05] <android14141480> But could you tell me how is called this channel
[19:34:38] <android14141480> Bellinganroy do you know name of the channel ?
[19:35:27] <BellinganRoy> Sorry I'm not aware of a plasma cutting related channel, but I think is safe to ask here the same!
[19:43:15] <android14141480> I have a new plasma cutter but i don't know why doesn't working. How psi i need for her?
[19:47:22] <BellinganRoy> android14141480: http://www.catb.org/esr/faqs/smart-questions.html
[19:48:53] <BellinganRoy> Not knowing even the cnc model, not anything...
[20:29:19] <PetefromTn_andro> Evening folks.
[20:32:54] <jdh> pete
[20:36:33] <Connor> I got stung in the face by a Yellow Jacket this afternoon... :(
[20:36:49] <PetefromTn_andro> Damn that bites Lol
[20:36:56] <Connor> No. It's stings.
[20:36:57] <Connor> :)
[20:37:12] <PetefromTn_andro> Jeez sorry to hear that dude.
[20:37:21] <Connor> $h!t Happens.
[20:38:49] <XXCoder> ow
[20:38:51] <PetefromTn_andro> Damn weekend flew by quickly
[20:39:06] <XXCoder> virtually no weekend for me, worked sat lol
[20:39:44] <PetefromTn_andro> I worked some both days but still flew by quicker than usual it seemed
[20:40:04] <XXCoder> 6 day workweek last 2 weeks
[20:49:39] <PetefromTn_andro> Damn I feel like I got a damn headache right now lol
[21:04:34] <PetefromTn_andro> Anyone making anything interesting with linuxcnc today?
[21:05:50] <XXCoder> yeah made trange thingy with angles 30 50 and 150
[21:10:13] <PetefromTn_andro> I finally learned how to figure cosine angels with my damn ti86 calculator today thanks to my pal art.
[21:10:38] <XXCoder> yeah prayer is tough to do ;)
[21:11:11] <PetefromTn_andro> I use it to figure the amount of droop in these custom scope rails I am machining here.
[21:11:36] <PetefromTn_andro> Harde har har
[21:12:25] <PetefromTn_andro> I had been doing everything in cad drawings to figure the MOA
[21:17:52] <PetefromTn_andro> I have bee n
[21:18:32] <PetefromTn_andro> Been doing a bunch of 3d cad drawing lately and I think I am finally getting the hang of it
[21:19:06] <PetefromTn_andro> I dunno where I would be without YouTube man seriously
[21:20:01] <Tom_itx> your tutor?
[21:20:17] <PetefromTn_andro> Damn right it is hehe
[21:20:59] <PetefromTn_andro> I swear you can learn just about anything on YouTube if you watch enough vids
[21:21:53] <PetefromTn_andro> I watch a lot of solidworks videos because it is similar to freecad and of course freecad vids are great too.
[21:22:04] <Tom_itx> just don't put it on your resume
[21:22:19] <PetefromTn_andro> Why not
[21:23:18] <PetefromTn_andro> It seems like there are quite a few pro online schools that post their videos on there or at least parts of their series
[21:24:13] <PetefromTn_andro> If you watch enough of them you will get a lot of tips and ideas and concepts about how things get done quicker and easier
[21:28:05] <PetefromTn_andro> I seriously doubt I would have been able to draw half the parts I have without it. So far I have built three different custom parts and sold the design to customers because of the 3d presentation. It's pretty cool!
[21:35:54] <XXCoder> yeah gonna figure freecad
[21:37:31] <PetefromTn_andro> Whaddyamean?
[21:37:43] <XXCoder> freecad is bit tough for me lol
[21:39:45] <PetefromTn_andro> Honestly 3d design has been tough for me in general even when I had access to solidworks it was confusing but like I said the YouTube tutorials helped a bunch
[21:40:12] <XXCoder> got link?
[21:40:57] <zeeshan> XXCoder: what is confusing
[21:41:05] <PetefromTn_andro> Man there are tons of em just search freecad or solidworks tutorials on YouTube.
[21:41:15] <XXCoder> lol ok
[21:41:23] <PetefromTn_andro> Seriously
[21:42:16] <PetefromTn_andro> Pick a tutorial that looks well done in your native language and just start watching and then pause and try it yourself in the program as you go along
[21:42:31] <XXCoder> nah impossible find in my own language
[21:42:36] <XXCoder> but yeah englisg is fine
[21:42:56] <PetefromTn_andro> You will learn the basics rather quicker
[21:43:01] <PetefromTn_andro> Quickly
[21:43:17] <zeeshan> XXCoder: what is hard
[21:43:33] <XXCoder> oh in general. I made few stuff in freecad
[21:46:36] <PetefromTn_andro> It's actually quite interesting to learn how the features work and seeing others draw there is always another way to accomplish the same thing perhaps quicker.
[21:47:40] <zeeshan> i think most things can be made using revolve, extruding
[21:49:23] <PetefromTn_andro> My biggest problem is I usually wind up screwing up the model somehow later on when I add features improperly which causes problems with previous stuff. And also I need to learn to add champfers and fillets at the end more than during.
[21:49:51] <zeeshan> PetefromTn_andro: do you constrain everything
[21:49:53] <XXCoder> one thing I hate is many ops is not reverseable
[21:50:07] <zeeshan> XXCoder: a lot is reversible
[21:50:11] <PetefromTn_andro> Yes generally
[21:50:16] <zeeshan> if you design it with flexibility in mind
[21:50:52] <PetefromTn_andro> Basically once you get the hang of how the flow works nothing should be irreversible
[21:51:13] <zeeshan> http://www.atpturbo.com/mm5/graphics/00000001/Catalog%20Images/Flanges/Steel/ATP-FLS-038_450.jpg
[21:51:18] <zeeshan> for example if youre making something like that
[21:51:28] <PetefromTn_andro> That's kind of the point of parametric modeling
[21:51:32] <zeeshan> and you know it might get bigger/smaller
[21:51:38] <zeeshan> or the bolt holes might change position
[21:51:54] <zeeshan> i take advantage of symmetry
[21:52:10] <zeeshan> so i'll start off with a rectangular piece with the origin at the center of it
[21:52:31] <PetefromTn_andro> I use symmetry and offset commands almost constantly
[21:52:49] <zeeshan> what do u mean by offset
[21:53:04] <Tom_itx> 3d would be a waste of time on that part
[21:53:13] <zeeshan> Tom_itx: you assume too much
[21:53:30] <PetefromTn_andro> I used the offset features to create my drawing entities and dictated dimensions
[21:53:54] <PetefromTn_andro> Why do you say that?
[21:54:03] <zeeshan> say what
[21:54:13] <PetefromTn_andro> It's a waste of time
[21:54:26] <zeeshan> cause he's assuming that i'd make that part
[21:54:28] <Tom_itx> because it's a very simple 2d part
[21:54:29] <zeeshan> for milling
[21:54:31] <zeeshan> or something
[21:54:38] <zeeshan> he doesnt realize it's a part needed for a larger assembly
[21:54:43] <PetefromTn_andro> It really depends on how it will be machined
[21:55:47] <PetefromTn_andro> Using the mastercam and solidworks they had at the shop making that part in 3d is about as quick as it would be 2d
[21:56:03] <zeeshan> fak autocad nonsense
[21:56:07] <zeeshan> and no parametric !
[21:56:17] <Tom_itx> i wouldn't use acad either
[21:56:28] <Tom_itx> it's not very good for cnc work
[21:56:57] <Tom_itx> i suppose it just depends how and what you are used to doing
[21:57:38] <Tom_itx> i've been sent a whole wing assembly just for a couple parts from it
[21:57:44] <PetefromTn_andro> Honestly up til this year basically everything I machined was made in an autocad clone
[21:59:04] <PetefromTn_andro> If the parts do not require 3d machining it is fine and rather quick and easy I think
[21:59:58] <Tom_itx> i would probably prefer working in solidworks but didn't start out with it
[22:00:46] <PetefromTn_andro> From the little time I was able to spend with it Solidworks is awesome wish I could afford it.
[22:01:47] <Tom_itx> it and the post you would need for it
[22:02:33] <PetefromTn_andro> I really wanted to spend some more Time with it and play with the draw 3d functions that us pretty cool.
[22:03:39] <PetefromTn_andro> Post?
[22:03:48] <Tom_itx> to generate gcode from it
[22:04:05] <Tom_itx> it doesn't natively have one that i'm aware of
[22:04:43] <PetefromTn_andro> I understand there are build in cam packages for it that are amazing and cheap or free but you gotta have a license for sw first
[22:05:07] <PetefromTn_andro> That's the spensive part Lol
[22:05:44] <Tom_itx> i've got an old version that has none that i'm aware of
[22:05:55] <zeeshan> what year
[22:06:01] <Tom_itx> but i haven't honestly looked that hard since i use smartcam
[22:06:04] <Tom_itx> i forget now
[22:06:06] <Tom_itx> it's pretty old
[22:06:10] <zeeshan> hsmxpress looks nice
[22:06:20] <zeeshan> mastercam for solidworks has been around for a while
[22:06:25] <PetefromTn_andro> Yup that's one of them
[22:06:37] <zeeshan> i need to relearn mastercam
[22:06:43] <zeeshan> ive spent too much time fucking around with nx
[22:06:53] <zeeshan> the tool paths are always something i dont want them to be
[22:06:56] <zeeshan> its irritating
[22:07:16] <zeeshan> has anyone here setup a cnc lathe with linuxcnc
[22:07:23] <zeeshan> and have all their tool offsets setup?
[22:07:41] <PetefromTn_andro> Mastercam seems pretty straightforward but there are so many options that are hard to understand to. Me
[22:07:50] <zeeshan> its not straight forward
[22:07:52] <zeeshan> for 3d stuff
[22:08:05] <PetefromTn_andro> I thought it was
[22:08:17] <zeeshan> since when did you start using it
[22:08:38] <PetefromTn_andro> When I worked in the shop that is all we used.
[22:08:46] <zeeshan> you programmed using mastercam?
[22:08:47] <zeeshan> personally?
[22:08:52] <PetefromTn_andro> Sure
[22:08:59] <zeeshan> lol
[22:08:59] <zeeshan> ok
[22:14:57] <PetefromTn_andro> Well it's getting late talk tomorrow guys . Night
