[00:33:12] <Tecan> how much is too much latency for a hardware driver ?
[00:33:52] <Tecan> rather communication between machine and emc
[00:35:12] <Tecan> cnc to emc
[00:52:28] <Tecan> tjb1... when you asked if there was a problem jymmm the other day how did you make that fon t ?
[00:56:27] <Tecan> telnet 192.168.1.1
[00:59:21] <mrsun> omg i got the ip for your rooter! now im gonna hack yo!
[00:59:24] <mrsun> ;)
[01:07:40] <Tecan> gcc main.cpp -z execstack
[01:08:25] <Tecan> ./a.out 99999999 dbus.xhcat.mrsun
[01:09:28] <Tecan> actually thats my wr703n thingi
[01:09:37] <Tecan> trying to setup a repeater
[01:09:43] <Tecan> adhoc
[01:09:57] <archivist> tjb1, "impose a line" ?
[01:09:58] <Tecan> wanna test some milliseconds out
[01:11:02] <archivist> tjb1, you can use features as references in later sketches and mates
[01:17:53] <Tecan> http://staff.aist.go.jp/y.oiwa/FailSafeC/index-en.html lol this is what i need
[01:22:24] <Jymmm> Tecan: ?
[01:22:34] <Jymmm> font?

[01:26:37] <Tecan> its got like a ton of shit in there for extra chars
[01:26:54] <Tecan> i didnt even know it was possible to have font stack vertically
[01:27:40] <Tecan> http://tinyurl.com/b7vypmz
[01:27:45] <Tecan> for better looking
[01:28:18] <Tecan> rather neat
[02:14:33] <DJ9DJ> moin
[04:31:06] <Tecan> http://stackoverflow.com/questions/161053/c-which-is-faster-stack-allocation-or-heap-allocation
[04:58:02] <TekniQue> Tecan: yep, and good answers as usual on stack overflow
[04:58:44] <Tecan> yep neat stuff
[05:03:17] <Tecan> using heap is good for lots of small shortlived things like particles or very large things
[05:03:51] <TekniQue> nah heap is better for long lived large things
[05:03:51] <Tecan> otherwise use stack its faster and less prone to fragmenting
[05:04:19] <TekniQue> because it has lots of space available but comes with an allocation time penalty
[05:04:27] <TekniQue> allocation and deallocation take time
[05:04:46] <TekniQue> stack has limited space so it's bad for large objects
[05:04:56] <TekniQue> but it's very fast to allocate
[05:05:30] <TekniQue> but has no way of dynamically deallocating because it is a stack
[05:05:57] <TekniQue> deallocation has to be done in reverse order of allocation
[05:06:14] <Tecan> ty for the input
[05:06:21] <Tecan> love irc
[05:06:39] <TekniQue> stack is what's used in a program when you declare a variable inside a function
[05:06:46] <TekniQue> as part of the function
[05:06:56] <TekniQue> int c; goes on the stack
[05:07:10] <TekniQue> and it's all deallocated once the function returns
[05:07:15] <Tecan> yeah to make it go into the heap you'd have to write a memory manager and overload the new function
[05:07:32] <Tecan> or just new something
[05:07:43] <TekniQue> every function call incurs a stack allocation
[05:08:02] <Tecan> hmmmm
[05:08:20] <TekniQue> with the parameters passed to the function and a pointer saying where to return
[05:08:50] <Tecan> so the whole main program is not allocated on the heap just main ?
[05:09:04] <Tecan> i gotta read more
[05:09:11] <Tecan> ;)
[05:09:16] <Tecan> bbiab
[05:11:04] <TekniQue> like I said, every function allocates from the stack
[05:12:30] <TekniQue> but the stack is just a regular block of memory
[05:36:10] <Tecan> cpufreq-info neat little tool to see how much users push their systems
[05:49:16] <Tecan> you guys tried out AutoKey for linux ?
[05:49:49] <Tecan> its dam handy but i cought it eating its whole thread resources the otherday looking for keypresses... something musta went amuck
[05:52:05] <p0g0> Tecan: is that a keyboard macro processor?
[05:52:29] <Tecan> yes
[05:52:47] <p0g0> for GUI and CLI?
[05:52:52] <Tecan> gui
[05:53:05] <Tecan> duno about the latter
[05:53:14] <p0g0> anyone remember Borland's Superkey?
[05:53:23] <p0g0> 1985-ish
[05:53:28] <p0g0> very handy
[05:55:08] <Tecan> "Controlling a laser with Linux is crazy, but everyone in this room is crazy in his own way. So if you want to use Linux to control an industrial welding laser, I have no problem with your using PREEMPT_RT." -- Linus Torvalds
[05:56:58] <nevyn> I'm trying to test linuxcnc with the -rt kernel patches (as I was already running them) but latency-test doesn't seem to change the priority of the spawned test threads to realtime
[05:57:31] <nevyn> so the current numbers I'm getting are... underwhelming.
[05:57:46] <Tecan> nevyn why not just use the iso ?
[05:58:01] <Tecan> its ready to rip
[05:58:07] <Tecan> or cut be it
[05:59:03] <nevyn> Tecan: because my laptop is already configured for realtime and tested with the -rt patches (I use it with jack)
[05:59:40] <archivist> nevyn, some interrupt or some dma may already have stolen the bus
[06:00:23] <psha[work]> nevyn: lack of permissions?
[06:00:23] <nevyn> archivist: so the problem I'm having is configuring linuxcnc and latency-test to use -rt
[06:00:55] <nevyn> in that it needs to configure the rt threads as sched_FIFO with some priority.
[06:01:13] <archivist> and are you using the recent linuxcnc version or what
[06:01:18] <nevyn> git.
[06:02:12] <nevyn> tho I was somewhat unclear as to whether the branch for rt had been merged or not.
[06:02:33] <Tecan> fopen("/sys/kernel/realtime","r"))
[06:03:36] <archivist> not sure the main git repo covers rt I think you should be using mhaberlers repo
[06:04:03] <nevyn> yep looks that way
[06:04:15] <nevyn> as git grep kernel/realtime returns nothing
[06:04:33] <mhaberler> what are you looking for ?
[06:04:34] <Tecan> same here
[06:05:00] <mhaberler> nevyn - any build questions?
[06:05:03] <Tecan> my linuxcnc box is not up atm tho im using lowlatency ubu
[06:06:06] <mhaberler> re merge: both rtos-integration-preview3 and rtos-integration-preview3-merged-into-master have support for Xenomai, RT PREEMPT and posix (sim)
[06:06:47] <mhaberler> the git.linuxcnc.org repo has none of that, pending build infrastructure support
[06:07:30] <Tecan> that sounds like alot of hardwork on your part
[06:07:43] <Tecan> you must be part machine to be able to do that
[06:07:48] <nevyn> mhaberler: :(
[06:08:00] <mhaberler> doable by humans (note plural)
[06:08:07] <mhaberler> several folks involved
[06:08:11] <Tecan> ;)
[06:08:16] <archivist> testing needed
[06:08:21] <mhaberler> so what was the issue again?
[06:08:41] <mhaberler> read back but cant tell
[06:08:47] <nevyn> mhaberler: so the big question is answered
[06:08:52] <nevyn> I've built the wrong branch ;)
[06:08:59] <Tecan> hehe
[06:09:01] <nevyn> mhaberler: the other questions I have are...
[06:09:31] <nevyn> It's not clear from the wiki if Xenomai is required to use PREEMPT_RT
[06:09:38] <mhaberler> no, it is not
[06:09:38] <nevyn> or if they're alternatives
[06:09:50] <psha[work]> alternatives
[06:09:56] <mhaberler> alternatives; in a few weeks they be runtime alternatives
[06:10:32] <mhaberler> same build for xenomai, rt-preempt, posix/sim - with autodetection; thats in the works but wont affect functionality or performance
[06:10:42] <nevyn> mhaberler: so of rtos-integration-preview3 and rtos-integration-preview3-merged-into-master what would be the reccomendation
[06:10:50] <mhaberler> yes
[06:10:59] <nevyn> mhaberler: "merged into master" is misleading ;)
[06:11:07] <mhaberler> depending if you prefer v2.5_branch or master
[06:11:12] <mhaberler> propose a name?
[06:11:37] <Tecan> unicnc
[06:11:56] <nevyn> mhaberler: "to be mainlined" "for master"
[06:11:57] <mhaberler> I'll tag it 'washer+dryer'
[06:12:03] <Tecan> :)
[06:12:14] <nevyn> in that "merged into master" suggest it's been done.
[06:12:30] <nevyn> and that the contents of this topic branch is now in mainline.
[06:12:57] <mhaberler> a short look at the commit history will fix that perception ;)
[06:14:36] <nevyn> so the difference between preview3 and preview3-merged-into-master is one is tracking 2.5 release and one is tracking master?
[06:14:41] <mhaberler> yes
[06:15:03] <mhaberler> I havent rebased in a while though
[06:16:03] <nevyn> so we ... (melbourne hackerspace) are building a trivial 2d plotter using linuxcnc and a arduino offload board ...
[06:16:04] <mhaberler> hm, actually Dec 20 for v2.5_branch, not so bad
[06:16:22] <mhaberler> it is a good idea to offload an arduino ;)
[06:16:25] <nevyn> it's this years project for the arduino miniconf.
[06:17:01] <nevyn> https://github.com/CCHS-Melbourne/HackCNC/tree/master/Docs
[06:17:05] <mhaberler> what exactly does the arduino buy in this setup?
[06:17:06] <nevyn> has the overview
[06:17:07] <mhaberler> ah
[06:17:35] <nevyn> mhaberler: it's an interface for the stepper drivers
[06:18:16] <mhaberler> so its a commanded position interface?
[06:18:57] <mhaberler> I'd think the USB link will introduce lots of position noise
[06:20:00] <mhaberler> I get the idea, and that's where I want to go with this ARM board stuff, but your interface is at the wrong layer - too low, too time critical
[06:20:37] <Tecan> mhaberler i cant find your repo
[06:21:00] <mhaberler> git.mah.priv.at
[06:21:15] <Tecan> heh it worked
[06:21:27] <mhaberler> git://git.mah.priv.at/emc2-dev.git
[06:21:47] <nevyn> mhaberler: it's not that smart.
[06:22:03] <mhaberler> try this: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?NewRTInstall
[06:22:48] <mhaberler> it will work in principle, but the timing will be lousy
[06:22:50] <nevyn> ok so I found AND in that first sentance confusing...
[06:24:17] <mhaberler> My goal is to cut between UI/task/interp and hal/motion and introduce a messaging layer; the second part would be perfect for these arm boards; the first part - soso; arduinos dont cut it for motion/HAL - too limited
[06:25:27] <nevyn> so you offload accel curves and everything to the arm?
[06:25:43] <nevyn> and send "go here"
[06:25:45] <mhaberler> it is already there
[06:26:06] <mhaberler> yes, that would be the idea, it's the motion/task interface; it just has no public API atm
[06:26:34] <mhaberler> 'go here' is time insensitive as long as you dont underrun the queue
[06:26:47] <nevyn> hrm.
[06:26:54] <nevyn> curves?
[06:27:08] <mhaberler> thats all in place, see the task/motion interface
[06:27:18] <nevyn> ok.
[06:27:28] <mhaberler> (it is one of the worst pieces of code in all of linuxcnc)
[06:27:35] <nevyn> eeek
[06:28:16] <mhaberler> that was very polite
[06:28:18] <mhaberler> http://git.mah.priv.at/gitweb/emc2-dev.git/blob/4a5c53ed6d8d8b7f9ee83d5cd2c0b67a4f855352:/src/emc/motion/usrmotintf.h, http://git.mah.priv.at/gitweb/emc2-dev.git/blob/4a5c53ed6d8d8b7f9ee83d5cd2c0b67a4f855352:/src/emc/motion/usrmotintf.cc
[06:28:38] <nevyn> is there a make dist ?
[06:28:47] <mhaberler> a what?
[06:28:59] <mhaberler> you mean a package build?
[06:29:05] <nevyn> no.
[06:29:21] <nevyn> a make mrproper (return source to "pristine")
[06:29:55] <mhaberler> at make level: make clean; at git level: git clean -xdf (and there go all the files you didnt add)
[06:30:13] <mhaberler> not sure, see src/Makefile
[06:30:14] <nevyn> oh the git clean I didn't know about thanks!
[06:30:32] <mhaberler> watch out, this cleans up _very_ thoroughly
[06:31:01] <mhaberler> it essentially restores the status of HEAD and nothing else
[06:31:03] <nevyn> so build a tree and run git status.
[06:31:11] <nevyn> and you have all the cat's and manpages and stuff
[06:31:31] <nevyn> and they're not in .gitignore (maybe they should be) maybe not...
[06:31:36] <mhaberler> was that a question?
[06:31:48] <nevyn> more an observation.
[06:32:29] <mhaberler> well, the linuxcnc build system needs a whole army of competent engineers, and we're happy to sign you up on the task ;)
[06:32:47] <nevyn> :)
[06:40:59] <nevyn> mhaberler: is --with-realtime=linux required as per http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Debian_Wheezy_Linux-Rt_Compile_LinuxCNC ?
[06:41:07] <mhaberler> no
[06:41:47] <mhaberler> just './configure' and it will default to the running kernel
[06:41:53] <nevyn> excellent!
[06:43:08] <mhaberler> I see, that wiki entry is a tad outdated - sorry
[06:43:29] <nevyn> no appologies required. just glad to be able to clarify things. ;)
[06:52:07] <r00t4rd3d> holy freezing balls
[06:52:10] <jthornton> I didn't even know we had tabs http://imagebin.org/243919
[06:52:31] <r00t4rd3d> -12F
[06:52:31] <r00t4rd3d> Sunny
[06:54:35] <Loetmichel> r00t4rd3d: thats a BIT cold...
[06:57:03] <Loetmichel> over here it is only -4°C... but the idea to walk the 20 min from doc to Pharmacy to get the drugs for the inflamed middle ear wothout an ear muff wasnt the greatest... still hurting... :-(
[06:57:29] <Loetmichel> ... and i was at the doc some 4 hrs ago
[06:57:59] <nevyn> hrm so I've built the right branch this time and run sudo make setuid
[06:58:10] <nevyn> but rtapp is still running SCHED_OTHER
[07:00:56] <nevyn> when running latency-test
[07:10:33] <mhaberler> I have no idea about SCHED_OTHER; post on the list please
[07:10:39] <mhaberler> what does the latency-test say?
[07:11:53] <nevyn> mhaberler: nothing good..
[07:12:24] <mhaberler> please look at config.log - it should say for which thread style it build - does it say 'looks like a RT_PREEMPT configuration' ?
[07:12:26] <nevyn> mhaberler: 1751473 768686
[07:12:42] <mhaberler> that aint RT PREEMPT
[07:12:56] <nevyn> yep
[07:13:07] <mhaberler> --> config.log - have a close look. what does the top line of 'git log' say?
[07:13:44] <mhaberler> please pastebin config.log
[07:14:06] <nevyn> sure
[07:14:43] <nevyn> http://paste.debian.net/227834/
[07:17:37] <mhaberler> first line of 'git log' please
[07:18:17] <nevyn> nevyn@cetacea:~/repos/linuxcnc/src$ git log|head -1
[07:18:17] <nevyn> commit 4b8dcbc9d0ed560bd9ca739efb01276462b260ff
[07:18:52] <mhaberler> which branch is this?
[07:19:14] <mhaberler> oh I see
[07:19:21] <mhaberler> -merged-into.. etc
[07:19:41] <mhaberler> and what type of machine, a laptop?
[07:19:47] <nevyn> yes....
[07:20:08] <mhaberler> sorry, we dont subsume laptops under 'realtime capable' over here, this is a waste of time
[07:20:24] <mhaberler> find some other PC - this wont get you anywhere
[07:20:54] <mhaberler> really - you're just in for endless pain with ths
[07:21:24] <archivist> nevyn, there is hardware power saving that gets in the way
[07:21:26] <nevyn> so the kernel rt bit isn't new.
[07:21:27] <mhaberler> built test - fine; timing figures tend to be outlandish
[07:21:49] <Tecan> the linuxcnc axiom
[07:22:14] <nevyn> the problem for me.. is that I can't see a thread that's marked anything other than SCHED_OTHER (not realtime)
[07:22:50] <nevyn> and AIUI rtapi_app SHOULD be SCHED_FIFI with some sane PRIO
[07:23:03] <mhaberler> please: summarize findings, and post on emc-developers - the folks which know about this dont hang out here
[07:23:48] <nevyn> archivist: so I've done the dance of tweaking that stuff for doing audio already.
[07:24:16] <mhaberler> audio is for whimps ;)
[07:24:28] <nevyn> :-P
[07:24:37] <mhaberler> measly buffering tricks
[07:24:39] <archivist> audio and holding a bit in the buffer is not hardware control
[07:24:52] <nevyn> yes we're talking 10's of ms rather than 1 I do see.
[07:26:18] <Loetmichel> *HRRRMP* I shgould have bought a 2.5mm Drill bit for the mill... the milldrilling with a 2mm 2-fute takes its time... 3/5 sheets done... -> http://youtu.be/BXNhsid6PD0
[07:35:41] <nevyn> hrm...
[07:38:44] <Tecan> http://upload.wikimedia.org/wikipedia/commons/0/09/Operation_Crossroads_Baker_Edit.jpg
[07:39:21] <mhaberler> hm, looks like a botched build
[07:40:07] <ReadError> anyone ever cut magnesium sheet?
[07:40:41] <mhaberler> this is very similar: trying to buy a Vienna subway ticket.. rings a bell? http://mah.priv.at/gallery2/main.php?g2_itemId=35682
[07:43:04] <Tecan> kernel panic :)
[07:43:56] <mhaberler> no, intrusion-secure OS by MS
[07:44:11] <Tecan> http://www.best-coupons-reviews.com/images/Bsod.jpg
[07:44:42] <Tecan> i remember seeing that screen before
[07:45:53] <Tecan> Goethe, Faust looks like a good read
[07:46:27] <mhaberler> and here we have a sample gdb session: http://mah.priv.at/gallery2/main.php?g2_itemId=35479
[07:46:46] <Tecan> hehe
[07:46:52] <r00t4rd3d> google makes $929 per second

[08:17:13] <TekniQue> r00t4rd3d: it's interesting to see that Y! is still #5
[08:19:19] <TekniQue> quite a few sites there I have never heard of
[08:45:28] <mrsun> hmm try to figure out whats wrong with the mill today .. will be fun or something :/
[08:54:28] <r00t4rd3d> id rather hunt down some blonde swedish girls
[10:02:44] <IchGuckLive> hi all
[10:04:40] <Tecan> the bikini swimsuit was named after the island in 1946. The two-piece swimsuit was introduced within days of the first nuclear test on the atoll, when the name of the island was in the news.
[10:06:42] <TekniQue> interesting coincidence
[10:17:54] <IchGuckLive> Tecan: is this a CNC theme O.O
[10:18:09] <Tecan> i might laser some of the pics
[10:18:19] <Tecan> interesting stuff
[10:19:43] <IchGuckLive> Tecan: the BW printings in laser is fabouless also on wood and then polished
[10:20:09] <Tecan> polished with a buffer ?
[10:20:20] <Tecan> or maybe stained then buffed ?
[10:21:18] <IchGuckLive> standard wood polish floos stuff
[10:21:19] <Tecan> http://en.wikipedia.org/wiki/File:Crossroads_baker_explosion.jpg
[10:22:00] <Tecan> that one musta been underwater
[10:28:19] <Tecan> 1954 film Godzilla, in which the 1954 U.S. nuclear test awakens and mutates the monster, who then attacks Japan before finally being vanquished by Japanese ingenuity.
[10:28:33] <Tecan> thats where that movie came from :)
[10:42:24] <tjb1> archivist: I mean pull geometry off a feature made in another sketch to use it in the current sketch
[10:43:39] <archivist> tjb1, when you draw a new line hover over the feature it will lock to it
[10:44:33] <archivist> you can also right click and associate (or mate or something not used for a month or three)
[10:45:30] <archivist> you can also create new parts while in an assembly and thus use features in other parts as references
[10:45:52] <archivist> it is a wonderful toy
[10:52:18] <tjb1_> Ill have to play some more
[10:52:28] <tjb1_> r00t4rd3d: that torque app sucks, always frozen or something
[10:52:54] <r00t4rd3d> buy the full version captn.hook
[10:53:56] <r00t4rd3d> fix that garbage bnc you are using too
[10:55:26] <archivist> cardboard wifi I bet
[10:55:51] <tjb1> bnc
[10:56:02] <tjb1> I switched to tethering so I could use tpb
[10:56:10] <tjb1> Im not buying it if it sucks
[10:58:32] <r00t4rd3d> the play store pro version I am sure works fine
[10:58:43] <r00t4rd3d> I havent tried the one i sent you
[10:58:53] <r00t4rd3d> did you get the adapter?
[11:06:43] <uw> anybody hear of white wolf machining?
[11:06:55] <uw> they make taig/sherline endmill adapters
[11:18:00] <IchGuckLive> uwthe adapters are the same as on all BOB SubD25
[11:18:34] <uw> BOB subD25?
[11:18:49] <uw> is that that the threading?
[11:19:21] <IchGuckLive> bo its the optoelektronik adafter for sharline
[11:19:51] <uw> i am confused
[11:20:35] <uw> it says "3/4" x 16 spindle endmill holders"
[11:21:56] <IchGuckLive> ah you looking for the spindel adapter
[11:21:59] <uw> it is pretty much this part but by another person http://www.ebay.com/itm/A2Z-CNC-Steel-End-Mill-Holders-Taig-Mill-w-Hex-Flats-/320994268377?pt=BI_Tool_Work_Holding&hash=item4abcbfd4d9
[11:22:07] <uw> yes
[11:22:44] <uw> however this white wolf guy is dead or quit the biz or just decided to start scamming everybody
[12:04:05] <IchGuckLive> hi all B)
[12:08:41] <mrsun> hmm if spindle is very lose can conventional milling drag the cutter into the material making stuff undersized ?
[12:08:48] <mrsun> cant find any error in movement of tables
[12:09:13] <mrsun> and if i did the results wouldnt be as good as i get in finnish etc as it would not correct itself with lost steps
[12:09:15] <archivist> loose spindle can be bad
[12:09:22] <mrsun> the dovetails i mean of it
[12:09:40] <mrsun> getting about 0.5mm undersized when i mill
[12:09:47] <archivist> is there a lot of chatter
[12:09:49] <mrsun> checked the end mill and its 7.98
[12:09:52] <mrsun> archivist, not realy
[12:10:01] <mrsun> some i guess but not very much
[12:10:19] <mrsun> made a hexagon and in two directions its realy big undersized
[12:11:05] <IchGuckLive> energy chain kable for the encoders what do you use for this
[12:11:21] <archivist> take too much and column twist/bend will cause a few errors
[12:12:03] <archivist> dti between table and head/spindle to check how rigid the machine is
[12:12:04] <mrsun> archivist, ye but feels like that error should be away from the material
[12:12:11] <mrsun> tho conventional milling pulls the cutter into the material
[12:12:19] <mrsun> gonna make a test with the same program but climb cutting
[12:12:26] <mrsun> and see if it gets oversized :P
[12:12:34] <IchGuckLive> im running on 400inch per min the hole day so it hat to be a very flex cable
[12:13:07] <IchGuckLive> mrsun: garbige clamp
[12:13:16] <IchGuckLive> get a holex mount
[12:13:26] <archivist> ?
[12:15:55] <archivist> mrsun, if your slides are now much tighter and friction is higher, lost steps and backlash problems will show up more
[12:16:38] <archivist> I have had unbalanced weight on the table cause friction problems too
[12:19:49] <mrsun> archivist, ye but lost steps would start to add up
[12:20:11] <mrsun> and as it doesnt "step" anywhere on the piece ven tho i make 10 passes downwards it deosnt feel like that
[12:20:11] <archivist> should add up but....
[12:20:40] <mrsun> but checked the tables now, the X table was a bit tight and the dovetails not straight :/
[12:20:45] <mrsun> so had to losen it up some
[12:21:17] <archivist> couplers coming loose is another thing that bites sometimes
[12:22:10] <archivist> cut a square and a circle and measure too
[12:22:11] <mrsun> still with a cut straight down in 10 increments it should show one one of the sides if im losing position
[12:24:52] <mrsun> but ye i will do tests =)
[12:25:49] <mrsun> but shouldnt a hexagon be a quite god test? :)
[12:25:56] <mrsun> as you got both straight moves and diagonal moves
[12:27:01] <archivist> a circle shows a transition when there is a backlash problem
[12:27:13] <mrsun> mm
[12:27:24] <mrsun> checked backlashes and have compensation in for it also
[12:27:30] <tjb1> r00t4rd3d: It works on my n7 but not the sg3
[12:27:31] <mrsun> but might have to measure more =)
[12:27:43] <mrsun> maybe take the 0.001mm indicator to get it realy down to the money :P
[12:27:48] <archivist> yes you might :)
[12:28:12] <mrsun> but with the indicator i used it was right on the money ... atleast down to 0.005
[12:29:38] <mrsun> well atleast the parts i did cut isnt totaly destroyed ... just two pieces for a 15mm "key?"
[12:29:49] <mrsun> so even tho their 0.5mm off its not so huge a deal :P
[12:33:28] <archivist> are your backlash fiddles from before the recent gib fixes?
[12:38:05] <mrsun> yes, but the cutting was before that also :P
[12:38:09] <mrsun> so gonna recheck it
[12:38:26] <mrsun> hooked up a digital caliper and looks like on X i got some backlash left
[12:38:43] <mrsun> on Y its righ ton the money no matter how far i move
[12:39:08] <mrsun> that was checked after gib fixes :P
[12:40:16] <archivist> I dont trust backlash comp too much as there is wear too, I rotate on the rotary so I am coming from one direction on x or y usually
[12:41:04] <tjb1> archivist: Is there a video that shows how to do that?
[12:41:13] <tjb1> The tranpose geometry thing
[12:41:35] <tjb1> I know in inventor you could click a button and grab the edge or lines in a solid and bring it to the current sketch
[12:41:41] <mrsun> archivist, nop but kinda the only option i have right now
[12:41:56] <mrsun> do not manage to get it any better with the nut adjustments on the mill
[12:42:37] <archivist> tjb1, you draw a line above a feature it will snap to it
[12:42:55] <tjb1> This wasnt a straight line though, it was an arc that had no areas to snap to
[12:42:57] <mrsun> need to redo the screws also .. my last attempt ended up with off center motor axle to screw :P
[12:42:59] <mrsun> hehe
[12:43:32] <archivist> tjb1, use the right arc type to get a sensible snap
[12:44:06] <tjb1> I wish I had some formal training in solidworks
[12:44:16] <tjb1> seems like everything I do requires 10 extra steps and seems half-asses :P
[12:44:19] <tjb1> assed
[12:44:36] <archivist> tjb1, I have had one day demo, read the help and play
[12:45:33] <archivist> it can be sensible to add axes for construction
[12:45:54] <tjb1> I have to figure out where the add axis button is
[12:46:00] <archivist> usually its trivial to snap to arc centers though
[12:46:05] <tjb1> I can only real do simple drawings and assemblies though
[12:46:58] <archivist> I have modelled a clock and all its gearing, the gear mates are really powerful
[12:56:43] <skunkworks> hmm - are other people having site outages?
[12:56:57] <skunkworks> http://www.hostdime.com/
[12:57:12] <skunkworks> http://www.linuxforum.com/
[12:58:01] <archivist> is today the aaronsw blank your site day
[13:47:46] <tjb1> Anyone know a command to convert drawings from mm to in?
[13:48:28] <IchGuckLive> Scale
[13:48:37] <skunkworks> scale it .03937?
[13:48:39] <IchGuckLive> 25.4 B) O.O
[13:49:05] <skunkworks> traceroute stops in atlanta....
[13:49:59] <tjb1> I scaled it but didnt know if there was an autocad command
[13:50:05] <IchGuckLive> tjb1: just save the file to inch in qcad
[13:55:16] <archivist> tjb1, some packages can use both and its just a display option
[13:55:44] <tjb1> Im cheap and use draftsight
[13:56:00] <archivist> no idea on that
[13:56:20] <archivist> read the fm each cad will be different
[14:10:09] <andypugh> In Inventor you can just type mm or in if you want a dimension to be other than the default for the document.
[14:10:49] <tjb1> I changed the units but it didnt change the drawing…oh well
[14:10:56] <archivist> you can insert either in solidworks
[14:12:03] <andypugh> You probbaly need to edit the dimension style.
[14:14:17] <tjb1> I need to buy a cad program
[14:14:22] <tjb1> I wont have solidworks after school
[14:14:40] <tjb1> So many to choose from though, I hear alibre is good but I missed the $100 sale
[14:27:48] <andypugh> There will be another
[14:28:09] <andypugh> Have a fiddle with Inventor Fusion (it's free)
[14:29:26] <tjb1> I did try it a bit
[14:31:45] <ReadError> solidworks is the only thing that clicked for me
[14:32:35] <archivist> I had a day on solid edge too was easy to play with
[14:36:13] <skunkworks> hmm - this seems like it could be a problem... http://www.internettrafficreport.com/history/295.htm
[14:36:43] <skunkworks> and http://www.internettrafficreport.com/history/120.htm
[14:48:06] <mrsun> yeah! getting closer
[14:48:14] <mrsun> the dovetails for the Z axis was lose ...
[14:48:46] <mrsun> tightened up the screw adjustments etc and readjusted backlash, but must have missed something on X
[14:50:31] <mrsun> now the parts dimensions are 14.96mm, (what it should be) 14.86mm 14.92mm
[14:50:37] <mrsun> should be 15 all the way around
[14:51:13] <mrsun> but atleast better then 14.5mm on one edge :P
[14:51:51] <mrsun> with some fiddling with it i should be able to get it a bit better, question is .. how high precision can you realy get with a micromill hogging steel ? :)
[14:56:11] <mrsun> tho its even worse when i think about it, the slot i milled for test with the 8mm endmill was 7.98mm .. so thats another 0.01mm on each side its hogging to much, part should have been oversized if anything!
[14:58:11] <tjb1> skunkworks_: what does that mean?
[14:59:33] <mrsun> 2.58mm WOC and 0.5mm DOC hmm
[15:48:39] <DJ9DJ> gn8
[16:02:24] <r00t4rd3d> tjb1, seems like no data is going through the network
[16:02:33] <tjb1> Hmm?
[16:03:17] <r00t4rd3d> tjb1> skunkworks_: what does that mean?
[16:03:36] <tjb1> Oh, I couldnt get the obd2 to work on the sg3
[16:03:46] <tjb1> gonna test is with new settings once I feel like freezing to death
[16:03:51] <r00t4rd3d> doesnt surprise me
[16:03:58] <r00t4rd3d> samsung suck
[16:04:58] <r00t4rd3d> they let the carriers fuck with the software too much.
[16:07:39] <r00t4rd3d> bluetooth has known issues in 4.2.1 also
[16:09:50] <r00t4rd3d> did you get any engine sound apps?

[16:29:29] <Valen> hilarious ESD testing
[16:58:50] <andypugh> Back to the discussion about temperatures yesterday. My multimeter thermocouple says that my body temp is 39C. I wonder if I shoiuld be concerned?
[16:59:35] <cradek> about your temperature or your thermocouple?
[16:59:57] <andypugh> That's the question, certainly.
[17:00:23] <andypugh> I wonder how accurate the thermocouple is?
[17:07:53] <mrsun> probably not calibrated for body temperature measurment ? :P
[17:08:10] <andypugh> It's a K-type, so I would think not.
[17:08:11] <mrsun> from what i understand thermometers for body is calibrated to measure it
[17:08:30] <mrsun> whacked it into your leg or something? :P
[17:08:34] <mrsun> thinking meat thermometer :P
[17:08:39] <andypugh> Of course, you only measure body temp when feeling ill, and I do.
[17:09:11] <mrsun> chills ? ... clothes moving over body feels like "pain" or something ?
[17:11:09] <andypugh> I just have a bit of a cold. But it is dragging on. I suspect that a week of effortful skiing at -20 was not a great recuperation strategy.
[17:11:54] <mrsun> haha
[17:12:08] <mrsun> not realy :P
[17:53:47] <Valen> andypugh: theres a long lasting virus going around at the moment
[17:54:03] <Valen> like a low grade flu but it seems to affect the sinuses
[17:54:30] <Valen> measuring your body temp without a virus is a good plan too, people run at different temperatures
[17:54:45] <Valen> my missus is about 1C warmer than i am normally
[18:03:00] <tjtr33> this morning nevyn ( from oz) showed his hackerspace's work, linuxcnc & arduino (jogging).
[18:03:06] <tjtr33> His overall diagram was done in DIA, but looked UML. I didnt know DIA handled UML, but does, and the idea maybe of use for some documentation.

[18:51:56] <r00t4rd3d> no
[18:52:16] <tjb1> I did :P
[18:54:27] <r00t4rd3d> did you get a engine sound app?
[18:54:48] <tjb1> no
[18:54:55] <tjb1> I dont have a loudspeaker
[18:55:13] <r00t4rd3d> it goes through your stereo
[18:55:36] <JT-Shop> how about a quietspeaker?
[18:55:56] <tjb1> I know r00t4rd3d, who is gonna hear it?

[19:07:08] <Jymmm> It be strange driving a stick with left hand I think
[19:08:09] <Valen> pshaw, its how its sposed to be
[19:09:20] <Jymmm> We drive on the RIGHT side, you drive on the WRONG side.
[19:10:30] <Jymmm> But, depending on where you area in the Bay Area, many drive on the wrong side =)
[19:11:00] <Valen> we drive on the correct side, you lot just decided to change to be narky
[19:11:40] <ReadError> hey
[19:11:46] <ReadError> who first mass produced the car?
[19:11:48] <ReadError> 'murica
[19:13:23] <Valen> the change happened well before the car
[19:13:49] <Valen> around the era of your "war of independence"
[19:14:59] <r00t4rd3d> probably Benz
[19:15:52] <r00t4rd3d> and was in Germany
[19:16:27] <r00t4rd3d> Ford was not the first to mass produce cars.
[19:17:06] <andypugh> Selden invented the car.
[19:17:59] <tjb1> Would turning a faucet on stop the pipe from freezing?
[19:18:07] <andypugh> Oh, no, wait. Selden _patented_ the car. Seems to be considered the same thing in the US.
[19:18:25] <Jymmm> tjb1: Yes, just barly let it drip
[19:19:04] <Jymmm> tjb1: still should instulate it where it's exposed outdoors if you can. even wrapping a towr around it
[19:19:11] <ReadError> ford made the production line
[19:19:13] <Jymmm> towel
[19:19:26] <ReadError> so he was the first mass producer
[19:19:37] <tjb1> Its under the house, older plumbing…the new ones under the house have heated wrap and insulation
[19:20:08] <Jymmm> tjb1: Ok, just let it drip a bit.
[19:21:25] <Valen> you need to understand how it stops it
[19:21:31] <ReadError> cutting some "XX Garolite"
[19:21:37] <ReadError> seems to cut pretty decent
[19:21:47] <ReadError> next im going to try this "Machinable Garolite"
[19:21:56] <Jymmm> tjb1: If you got a bucket, at least try to recover as much water as you can, plants, washing whatever.
[19:22:10] <tjb1> I'm not at home, telling my mom to do it
[19:22:33] <Jymmm> same thing
[19:22:35] <ReadError> they mail your printer tjb1 ?
[19:22:41] <tjb1> It will be here friday
[19:24:45] <Jymmm> Hmmm, disconnect the fuel filter, and feed the N2 tank into the fuel line WITHOUT a regulator =)
[19:25:06] <andypugh> ReadError: Ah, phenolic composites. The big brand here is Tufnol, and they have different types designated "Whale Brand", "Carp Brand", "Vole brand" http://www.tufnol.com/tufnol/default.asp?id=21
[19:26:26] <ReadError> andypugh, yea, ive mostly done G10
[19:26:28] <Jymmm> OH! I know... pressurize the fuel tank from a nitrogen one =)
[19:26:35] <ReadError> it cuts nice, but this is some 1/4" thick stuff
[19:26:47] <ReadError> i could see several endmills getting toasted in the process
[19:27:13] <Jymmm> paper phonelic... that shit is a butch to cut!!!
[19:27:20] <Jymmm> bitch
[19:27:37] <ReadError> well i can get it to cut decent
[19:27:39] <Jymmm> I took a torch to it for 5m, just chared slightly.
[19:27:47] <ReadError> i just destroy endmills ;)
[19:27:55] <Jymmm> yeah, need carbon
[19:27:58] <ReadError> so ive been using $3 ones from ebay so i dont feel bad about tossing them
[19:28:29] <ReadError> they actually work fairly well
[19:28:32] <Jymmm> I just use the piece I have as a non conductive heat barrier
[19:28:39] <Jymmm> too expensive =)
[19:29:48] <ReadError> cranking along at 20IPM on this
[19:29:55] <ReadError> i could probably go higher maybe
[19:30:23] <ReadError> low DOC though, its my aluminum toolpath
[19:30:27] <Jymmm> man this sucks... I can get a in-tank fuel pump for $25 off ebay, but if it dies in 30d, I have to drop the tank AGAIN.
[19:30:55] <Jymmm> And I cant seem to find external one, and dont' know if it'll fail emissions visual inspection.
[19:31:29] <Valen> there is a special way of sharpening stuff to cut fiberglass
[19:31:44] <Valen> i don't know what it is but my dad used to work in fiberglass for 30 years
[19:32:10] <Valen> if he "sharpened" a drill it'd do a buttload of holes, a new one from the box would do 50-100
[19:32:42] <Jymmm> My glass drillbits are blunt edges
[19:32:54] <Jymmm> glass/concrete/ceramic
[19:32:58] <ReadError> someone told me, rotozip bits
[19:33:03] <Valen> something like that as i vuagley recall
[19:33:06] <ReadError> with the little bump style teeth
[19:33:21] <Valen> (garolite is just fiberglass basically)
[19:33:25] <Jymmm> ReadError: those are abrasive cutters, kinda icky
[19:34:04] <Valen> most of the cutting of finished parts they did was with a die grinder with a diamond blade in it
[19:34:11] <Jymmm> I just use LOTS of water and take my time and I get a perfect holes.
[19:34:33] <Jymmm> Do use a backer so it doesn't chipout the back though.
[19:34:43] <Valen> masking tape ftw!
[19:35:03] <Jymmm> Not for ceramic though, needs to be solid and flush
[19:35:20] <Valen> I have milled glass on our mill ;->
[19:35:37] <Valen> used a diamond burr and did it in a water bath
[19:35:50] <Jymmm> this isn't diamond
[19:36:07] <Jymmm> it's a spade bit

[20:20:40] <Tom_itx> do more research
[20:20:45] <ReadError> yea thats what i figured Tom_itx
[20:20:48] <Jymmm> I need to sell mine.
[20:20:51] <ReadError> i dont want to rush into this
[20:20:53] <ReadError> and be unhappy
[20:21:37] <Tom_itx> decide what you want to do with it first
[20:21:47] <ReadError> well i have that decided
[20:21:55] <ReadError> light aluminum, g10 and CF
[20:22:05] <Tom_itx> if you buy a router and really wanted a mill you will be dissapointed
[20:22:12] <ReadError> well i got a small mill
[20:22:20] <ReadError> its basically for 2.5d stuff
[20:22:29] <ReadError> very light on the Z axis
[20:22:40] <ReadError> all the cutting itself is done on 2d
[20:24:01] <ReadError> basically i want to lay down around 2 24x24" sheets
[20:24:05] <ReadError> and let it run the toolpath
[20:24:48] <Jymmm> 24" x 24" x 6" travel, 2.25HP 18-25K RPM spindle, 80/20 frame, energy chain, 230 steppers, xylotex controller PLUS Parker OEM650 controllers, DIN rail, 48V PS, dust enclosure, etc.
[20:25:08] <Tom_itx> for free?
[20:25:23] <r00t4rd3d> ill trade you ReadError little sister forit
[20:25:53] <ReadError> where are you at Jymmm ?
[20:25:57] <Valen> theres sisters being traded here?
[20:25:59] <Jymmm> Safety relay, 24V LED industrial controls, aluminum chassis enclosures, PANDUIT!, cabling, etc
[20:26:05] <Jymmm> ReadError: SFO
[20:26:21] <ReadError> san fran ?
[20:26:28] <Jymmm> yep
[20:26:32] <ReadError> yikes
[20:27:51] <Jymmm> Thomson ball screws on XY, Acme on Z. 20 or 22mm Abba linear rails, zirk fittings on the trucks, grease gun,
[20:28:09] <Jymmm> the list goes on and on and on
[20:28:13] <Tom_itx> free delivery?
[20:29:01] <ReadError> price ?
[20:29:03] <Jymmm> Extra risers for the Z to go from 0-6" to 3"-9", good for engraving the top of jewlery boxes, etc
[20:30:02] <r00t4rd3d> why you getting rid of it, too complicated?
[20:30:05] <Jymmm> the Parker based contrller isn't built, but I had been collecting all the parts for it.
[20:30:23] <Jymmm> r00t4rd3d: I have a laser now. It's what I always wanted in the first place.
[20:30:28] <r00t4rd3d> oh
[20:30:47] <ReadError> http://25.media.tumblr.com/tumblr_mad2p0Sy101rg9f11o1_500.jpg
[20:30:52] <ReadError> that would totally be me with that
[20:31:26] <Jymmm> Also, on the xylotex it would stall on high speed travel. But that's only 24VDC and the motors are good for at least 50VDC and the Parkers do that just fine.
[20:31:37] <r00t4rd3d> http://www.ebay.com/itm/Prusa-i3-Frame-Laser-cut-kit-RepRap-Mendel-3D-printer-Kit-NEW-/150967057341?pt=LH_DefaultDomain_0&hash=item2326567bbd
[20:31:45] <r00t4rd3d> I could make that
[20:32:02] <Jymmm> Also have 17,000uf 400V caps, mounting clamps
[20:32:27] <ReadError> seemecnc has you beat r00t4rd3d
[20:32:30] <jdh> xylotex fries at 35V
[20:32:31] <ReadError> he laser cuts em
[20:33:15] <jdh> I run my at 30V.. the tweaker on the 24V PS will go up to 33 or so
[20:33:25] <Jymmm> DIN rail safety relay, din rail fuse holders, din rail PS, din rail terminal, din rail db25 breakout,
[20:33:44] <Tom_itx> why are you parting with it?
[20:34:18] <Jymmm> jdh: Yeah, I know. just underpowered for the motors/ machine
[20:34:19] <ReadError> any pics of it Jymmm ?
[20:35:25] <Jymmm> http://i52.tinypic.com/nrndu.jpg

[20:37:11] <Jymmm> The dust enclosure just bolts together and to the gorilla rack it sits on. The walls are skinned with viynl ans metal screen with static groundig straps
[20:37:43] <Jymmm> Can connect 2.5" or 4" exhaust duct to the rear, fresh intake from the top.
[20:38:06] <ReadError> whats in that PCV tube?
[20:38:26] <jdh> for-sale flyers
[20:39:01] <Jymmm> the extra cord from the router motor so you can pull it out and use manually if you like without having to "unwire" everything.
[20:39:37] <Jymmm> 1/4, 3/8 and 1/2" collets
[20:41:31] <Jymmm> It's really a Bosch router OEM'ed as Craftsman Professional with the fixed and plunge bases too... http://i46.tinypic.com/bhav0m.jpg
[20:42:45] <Jymmm> Sears doesn't carry the 3/8" collect, I got that directly from the Bosch service center =)
[20:43:15] <r00t4rd3d> http://www.thingiverse.com/thing:40465
[20:44:44] <ReadError> thingiverse aka selloutplanet
[20:45:22] <Jymmm> It is a K2cnc frame, but they dont make this design anymore http://www.k2cnc.com/product_kg2525.aspx
[20:45:48] <Jymmm> antibacklash nuts on the z acme, thumpson ballnuts on xy
[20:46:12] <r00t4rd3d> so what you want for it?
[20:47:10] <Jymmm> I'm really not sure, $4200 or so
[20:47:28] <r00t4rd3d> wow
[20:47:36] <Jymmm> What?
[20:47:48] <Jymmm> it's not a MDF router
[20:48:12] <r00t4rd3d> either is mine, anymore.
[20:48:31] <Jymmm> the parts I've cllected for the new controller are $1000 alone.
[20:49:03] <Jymmm> there are a coule of computers included as well.
[20:49:04] <r00t4rd3d> for the size just seems crazy expensive
[20:49:32] <Jymmm> r00t4rd3d: Not really http://www.k2cnc.com/product_kg2525.aspx
[20:49:47] <Jymmm> they START at $7500
[20:50:17] <Jymmm> And we've tossed in on a granite slab... it's damn square
[20:51:04] <r00t4rd3d> lol, 2x2 for 8k
[20:51:27] <r00t4rd3d> you would have to be a serious fucking dumbass to pay that.
[20:53:39] <Jymmm> This is 4" http://i39.tinypic.com/iefmgy.jpg
[20:54:07] <Jymmm> Same artwork, just inversed http://i42.tinypic.com/15hft77.jpg
[20:54:20] <Jymmm> Both are MDF
[20:58:11] <Jymmm> The router carved this as well into mdf, about 8" wide http://i52.tinypic.com/r1lwra.jpg then hand painted.
[20:59:00] <r00t4rd3d> this is the smallest ive done http://i.imgur.com/Mz2k9kp.jpg
[20:59:15] <r00t4rd3d> oval was 4" and text was 2" wide
[20:59:25] <r00t4rd3d> in oak
[20:59:49] <r00t4rd3d> on my redneck 800 w/computer monitor setup.
[21:00:00] <Jymmm> me messing around... 4"x4" maze http://i55.tinypic.com/28lf0b6.jpg and 2" sq 3/4" tall http://i54.tinypic.com/28ilw0w.jpg
[21:04:07] <r00t4rd3d> ReadError, how big of a cutting area you looking for?
[21:04:15] <ReadError> 24x48
[21:04:35] <r00t4rd3d> so diy is pretty much your choice
[21:04:49] <ReadError> ya or the rack and pinion setup from cncrouter parts
[21:04:55] <ReadError> but im hesistent about that
[21:05:06] <ReadError> hesitant
[21:07:14] <r00t4rd3d> look at post #1682
[21:07:15] <r00t4rd3d> http://www.cnczone.com/forums/diy-cnc_router_table_machines/109390-my_newest_desktop_machine-141.html
[21:07:48] <r00t4rd3d> can you do that on your mill?
[21:08:12] <r00t4rd3d> http://www.microcarve.com/ebayz35ext2/
[21:09:50] <ReadError> yea i could do that
[21:10:05] <ReadError> self made z axis ?
[21:15:56] <r00t4rd3d> I would mill as much stuff as i could
[21:16:15] <r00t4rd3d> motor mounts, couplers, etc
[21:37:58] <AR__> parts for my DIY z axis are on the way
[21:38:01] <AR__> it will be similar to that
[21:38:35] <AR__> except using 4 thomspon super pillow blocks with precision steel bearings
[21:40:18] <AR__> http://i.imgur.com/swEaBhU.jpg
[21:40:47] <AR__> the bearings and ballscrew sitting on top will be part of the Z
[21:42:16] <AR__> http://i.imgur.com/rDDlt7K.jpg
[21:43:35] <AR__> btw i am not using that little 1/4" plate for a saddle
[21:44:22] <AR__> i have two 1/2 plates on the way that i will bolt to the bearings and ballnuts on X and Y separately, then bolt them together
[21:44:34] <AR__> should allow for some adjustment/shimming if needed
[21:49:24] <r00t4rd3d> dude
[21:49:42] <jdh> sweet!
[21:50:41] <r00t4rd3d> crash waiting to happen.
[21:50:52] <AR__> it doesnt
[21:51:15] <AR__> i promise
[21:51:33] <r00t4rd3d> still I dont like that design one bit.
[21:52:07] <AR__> just the motor?
[21:52:25] <r00t4rd3d> that, how its stacking up
[21:52:34] <AR__> http://i.imgur.com/uzbocLZ.jpg
[21:52:57] <AR__> there's enough room
[21:54:05] <AR__> if i get a bigger motor i would probably flip the motor around though
[21:54:49] <AR__> i was testing the axis and i already crashed, technically :P
[21:55:21] <AR__> see that one long bolt i put in at the end of the rail to keep the bearings from sliding off when i didnt have the ballscrew on?
[21:55:53] <AR__> i was testing and jogged into it and was wondering why my ballscrew was pulling out of the end bearing blocks......
[21:57:43] <r00t4rd3d> where you getting these build plans from?
[21:59:02] <tjb1> r00t4rd3d: you are a party pooper
[22:00:28] <r00t4rd3d> Am i the only one who thinks he is going to have issues with that setup ?
[22:01:23] <tjb1> Its too late for me to tell what I am looking at
[22:01:37] <AR__> r00t4rd3d, my mind
[22:04:53] <archivist> r00t4rd3d, it has the better rail support than most round rail types, what are you thinking
[22:13:07] <AR__> i think it will be an excellent design for the price
[22:13:41] <AR__> i could have saved money if i knew what i needed and ordered things at the same time
[22:18:02] <r00t4rd3d> archivist, I dont like where the x motor is, dont like how the y axis is designed with pillow blocks acting as inverted rail supports, ummmmmm
[22:18:24] <tjb1> r00t4rd3d: did you fix your messy wiring yet?
[22:18:48] <r00t4rd3d> i took my machine all apart yesterday cause of the cold and brought it inside.
[22:20:13] <r00t4rd3d> dammit I have to leave the house
[22:20:18] <r00t4rd3d> -3F
[22:20:20] <archivist> motor location is not a problem
[22:20:28] <r00t4rd3d> till you crash into it
[22:20:53] <archivist> he wont crash if he has limit switches
[22:21:04] <archivist> it is incomplete
[22:21:32] <r00t4rd3d> i just dont see why you would put it there when you could put it on the back side and not worry about it
[22:22:43] <r00t4rd3d> his x would fall off the rails before it hit anything
[22:23:02] <archivist> worse
[22:23:39] <archivist> if the software and homing is set up correctly one cannot crash either
[22:24:05] <r00t4rd3d> well that is normally a learning curve for diy.
[22:24:10] <r00t4rd3d> hope he learns quickly
[22:24:40] <Tecan> http://resources.yesican-science.ca/trek/scisat/final/images/trans_spectrometer1.jpg wonder what ide use for a detector
[22:24:43] <archivist> its a lot better than some diy I have seen
[22:24:50] <r00t4rd3d> sure
[22:24:54] <r00t4rd3d> he has some nice parts too
[22:25:25] <archivist> Tecan, a slit and any wide band detector
[22:25:42] <Tecan> awesome
[22:26:21] <archivist> Tecan, I have a motorised version of that setup
[22:26:43] <Tecan> what did you use for a laser ?
[22:27:09] <archivist> its a spectrometer, no laser involved
[22:27:45] <Tecan> its for analyzing substances correct ?
[22:28:02] <Tecan> guess you could use any light source
[22:29:20] <archivist> well for substances the light matters, also depends on technique, flourescent, reflection, transmissive
[22:29:52] <Tecan> what do you use it for ?
[22:30:16] <archivist> it was cheap on fleabay, just to play with
[22:30:59] <archivist> I also have a transmissive one from scrap, ex forensic lab probably
[22:32:38] <archivist> I used to work fixing TVs and later manufacuring colour printers so have some interest in colour/lighting
[22:35:32] <Tecan> very cool!
[22:35:37] <Tecan> ham too ?
[22:36:48] <archivist> I let the licence lapse
[22:37:30] <tjb1> Would alibre be worth it for $100?
[22:49:05] <r00t4rd3d> Ill sell you a copy for 50.
[22:49:07] <r00t4rd3d> :D
[22:49:46] <tjb1> I dont want a pirate bay special
[22:50:25] <r00t4rd3d> i was joking. tpb only has 2011 anyway.
[22:50:45] <tjb1> I miss demonoid
[22:50:58] <archivist> form an educational institution and get a solidworks education license
[22:51:14] <tjb1> I "have" solidworks
[22:51:48] <archivist> you have the best already then
[22:51:58] <tjb1> The educational copy wouldnt install so I have one from r00t4rd3d favorite website
[22:52:20] <r00t4rd3d> fecalfetish.com ?
[22:53:24] <r00t4rd3d> eww thats forsale.
[22:54:11] <r00t4rd3d> that would be a good parody site.
