[00:02:12] <rlockwood2> http://www.mesanet.com/
[00:09:08] <Tecan> oh i see its a gcode interpreter
[00:18:20] <Tecan> http://smoothieware.org/
[00:20:26] <Tecan> looks like quite a bit of delay http://www.youtube.com/watch?v=3CYaGMgO-XQ
[00:34:01] <tjb1> I found my parport address
[00:34:11] <tjb1> Thats the good news…bad news is my hal and ini are a mess
[00:35:06] <tjb1> More bad news, charge pump doesnt work on PCI par port but does on mobo parport
[00:35:48] <Tecan> how is it set even ?
[00:35:59] <Tecan> the charge pump that is
[00:36:20] <Tecan> oh i see for going longer distances ?
[00:36:27] <tjb1> No
[00:36:38] <tjb1> Its a signal from the computer that lets the driver know its responding
[00:37:01] <tjb1> Maybe not the best explanation but without charge pump signal, driver shuts off
[00:38:00] <JesusAlos> Some body know why in linuxcnc pncconf wizard don't are 5i25 card
[00:38:02] <JesusAlos> ??
[00:38:17] <JesusAlos> only 5i20
[00:38:18] <Tecan> http://i.imgur.com/fOqUUt2.jpg << funny
[00:53:34] <Tecan> http://en.wikipedia.org/wiki/Charge_pump this is not telling me much... is a charge pump required for PLL ?
[00:54:47] <tjb1> PLL?
[01:00:02] <tjtr33> that wikipedia explanation is not the kind of charge pump used here. Here, its a 'keep-alive' signal if you dont hear the heartbeat of the chargepump, the system should stop
[01:01:03] <tjtr33> and no PLL involved
[01:03:36] <tjtr33> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?About_Charge_Pumps
[01:03:39] <tjb1> Its not required on my driver, I just like to use it
[01:06:22] <tjtr33> did you find the pport addr?
[01:09:15] <tjb1> Yes, it was 1008
[01:09:22] <tjb1> I have other problems now though
[01:09:34] <Tecan> http://www.youtube.com/watch?v=xIl45f6i1PU << bubble soccer
[01:10:51] <tjb1> I have to clean up/re-do my HAL file
[01:25:47] <Tecan> tjb1 i would assume that the board used to send the charge pump is capable of detecting one without special hardware too ?
[01:25:58] <Tecan> parport
[01:26:18] <tjb1> You mean the computer detecting the charge pump signal?
[01:26:45] <Tecan> no if another card sent it one
[01:26:58] <Tecan> yes
[01:28:13] <tjb1> That would just be a frequency so I don't see why not
[01:28:42] <tjb1> I believe you have to set EPP mode for the charge pump to work correctly and I cant do that with my PCI card but I can with the mobo port
[01:29:12] <Tecan> ah ic thanks for clarifying :)
[01:30:58] <tjb1> I think its a 50KHz signal
[01:31:27] <Tecan> wow
[01:31:47] <Tecan> i should make myself a oscilliscope
[01:32:25] <tjb1> Sorry its a 10kHZ
[01:32:28] <tjb1> kHz...
[01:32:46] <tjb1> Well the G540 requires 10kHz
[01:33:00] <tjb1> I got a Rigol DS1052E
[01:33:04] <tjb1> Thats hacked to the 100
[01:33:18] <tjb1> 100 MHz hack
[01:47:17] <Tecan> http://yp.shoutcast.com/sbin/tunein-station.pls?id=9490734 haha i listen to this to brush up on my russian
[01:56:58] <tjb1> I go play with my cnc to brush up on my french
[02:04:31] <r00t4rd3d> i go play with my cnc to fill up my pockets with money
[02:08:05] <Tecan> http://code.google.com/p/rsteppercontroller/
[02:08:45] <Tecan> r00t4rd3d are you a pro ?
[02:08:59] <Tecan> the artist of artists or what ?
[02:20:29] <Tecan> 7I80DB Ethernet Anything I/O card from mesa looks good
[02:21:27] <tjb1> Goodnight everyone
[02:21:36] <tjb1> Yeah, you could call r00t4rd3d a "pro"
[02:21:37] <tjb1> ;)

[07:00:52] <Loetmichel> mornin'
[07:01:39] <ReadError> hey Loetmichel
[07:01:48] <ReadError> you seen my new quad cnc creations?
[07:01:57] <Loetmichel> no

[07:03:11] <Loetmichel> soo, Mill ist "snowing" again... nor i will grant myself a coffee and then i will put on something more decent than a morning gown ;-)
[07:04:04] <Loetmichel> ReadError: hmm, fat aluminium. isnt that a bit heavy?
[07:04:35] <ReadError> on the little one
[07:04:38] <ReadError> only 6g
[07:04:44] <ReadError> with motor mount built in
[07:09:41] <Loetmichel> nice
[07:10:04] <Loetmichel> have you tried to use alu-dibond instead of massive aluminium sheet?
[07:10:21] <Loetmichel> should be lighter at roughly the same rigidity
[07:11:14] <IchGuckLive> ReadError: is this massive alu
[07:11:29] <ReadError> well i was thinking about using XX (G10ish material)
[07:11:41] <ReadError> density wise its about half of aluminum
[07:12:18] <IchGuckLive> just go to the next dragen store and take carbon fiver
[07:12:27] <IchGuckLive> its 2eur a pice
[07:13:03] <ReadError> 'take' ?

[07:16:29] <IchGuckLive> hi alan
[07:16:35] <Guest28963> hi
[07:16:41] <IchGuckLive> B)
[07:17:52] <alan-1234> does anyone know how to control the width of a pyvcp spinbox element? They make my panels too wide with a big open space on one side.
[07:19:13] <IchGuckLive> vbox
[07:20:35] <IchGuckLive> alan-1234: look at page 108 in the integreater manual
[07:23:31] <IchGuckLive> im off by til 19:00 Berlin time
[07:35:26] <Tecan> http://en.wikipedia.org/wiki/File:25_Pin_D-sub_pinout.svg
[07:35:31] <Tecan> whats strobe ?
[07:37:35] <archivist> a signal that latches all the other signals in a set
[07:39:45] <Tecan> Wang had a surplus stock of 20,000 Amphenol 36-pin micro ribbon connectors that were originally used for one of their early calculators, which they used to create the Centronics interface on their computers.
[07:40:09] <Tecan> hehe funny history
[08:14:27] <JesusAlos> http://www.linuxcnc.org/index.php/english/forum/39-pncconf/21670-5i25-firmware-xml-files-for-pncconf
[08:14:51] <JesusAlos> I don't know where put the file 5i25_desc.zip
[08:15:02] <JesusAlos> Moderator don't say
[08:15:17] <JesusAlos> eny body know?
[08:19:37] <r00t4rd3d> /usr/share/doc
[08:19:44] <r00t4rd3d> i would guess
[08:27:35] <JesusAlos> 're you sure?
[08:28:31] <JesusAlos> yes
[08:28:38] <JesusAlos> is the same name directory
[08:28:54] <JesusAlos> thank r00t4d3d
[09:12:34] <r00t4rd3d> im not sure, just guessing
[09:12:40] <r00t4rd3d> cause thats where the other one goes
[09:17:20] <Tom_itx> no
[09:18:05] <atom1> it goes in\lib\firmware\hm2\
[09:18:10] <atom1> in it's subdirectory
[09:18:25] <atom1> pretty sure
[09:53:45] <Jymmm> andypugh: http://oldfuelinjection.com/?p=95
[09:56:56] <archivist> that is not old injection this is http://www.collection.archivist.info/archive/Lucas/PS/PB7A/ps2233.jpg
[09:57:02] <DaViruz_> that "under construction" picture sure takes you back to the 90's
[09:57:57] <Jymmm> andypugh: Specifically... "High-pressure fuel pumps are not that good at pulling fuel out of gas tanks. That�s why new vehicles sold today have fuel pumps inside the tank."
[09:58:39] <archivist> today! been going on since a long time
[09:59:04] <Jymmm> ?
[09:59:46] <archivist> Jymmm, why are you trying to teach andypugh to suck eggs, you do remember his day job?
[10:30:18] <JesusAlos> f
[10:32:52] <Tecan> http://www.ebay.ca/itm/Altera-Cyclone-II-FPGA-EP2C5T144-Mini-Development-Learn-Core-Board-E081-/261095727391?pt=LH_DefaultDomain_0&hash=item3cca84a11f
[10:41:53] <awallin> Tecan: how does that one compare to the Spartan 3:s that are on the mesa cards?
[10:43:41] <Tecan> hmmm
[10:45:09] <awallin> you'd have to come up with your own pc-interface and driver for the altera...
[10:45:22] <awallin> do you know how the vhdl firmware tools for altera compare to xilinx ?
[10:45:38] <Tecan> http://www.ebay.ca/itm/XC3S250E-XILINX-Spartan-3E-FPGA-Evaluation-Development-Core-Board-XCF02S-FLASH-/261136054698?pt=LH_DefaultDomain_0&hash=item3cccebf9aa
[10:45:53] <Tecan> maybe i have to buy one of these now too
[10:46:00] * Tecan feels his pockets
[10:46:10] <awallin> umm, altera or mesa?
[10:46:25] <Tecan> spartain 3 fpga evaluation board
[10:46:54] <Tecan> there arnt any prices on the mesa website which makes me leary
[10:47:06] <awallin> for linuxcnc use a mesa card with a spartan 3 is a tried and tested solution
[10:47:15] <awallin> there is a pdf with prices on the mesa website
[10:47:43] <Tecan> whats one of those run in price ?
[10:48:14] <awallin> the 5i20 PCI card is under 200 I think
[10:48:38] <awallin> if you are in the US shipping is cheaper, elsewhere it's a bit more..
[10:49:05] <awallin> http://www.mesanet.com/prices.pdf
[10:49:39] <awallin> I'd like to develop some custom ADC and DAC cards + firmware for the mesa card, but so far I haven't had time..
[10:50:03] <pcw_home> That Altera chip is about the equivalent of a spatan3 XC3S200
[10:50:14] <pcw_home> spartan 3
[10:51:39] <awallin> pcw_home: do you have any comment on the altera toolset vs. xilinx? i.e. editors/compilers/debuggers etc
[10:52:44] <pcw_home> Not enough experience with Altera to say but I have heard that their tool chain (Quartus?) is less buggy
[10:54:56] <pcw_home> Though the latest Xilinx webpack (14.3?) seems pretty good
[10:55:46] <awallin> I've installed that webpack both on win and linux but haven't had time to play with it..
[10:55:57] <awallin> the ubuntu install did require some tweaking..
[10:58:57] <Tecan> git://git.linuxcnc.org/git/hostmot2-firmware.git
[10:59:50] <awallin> yeah, understanding the current firmware is probably the first step - before creating custom firmware
[11:00:12] <awallin> I'm not sure how many mesa users have compiled their own firmware with xilinx webpack - not many I guess
[11:00:30] <Tecan> hehe
[11:02:28] <Tecan> funny ive just been using my standart printer port for my machine and its awesome no jitter. probably dont need one of these cards just yet till i get into the 5 axis metal work lathe's
[11:02:31] <awallin> Tecan: if you do that, do write down some notes to help others in the wiki!
[11:02:41] <Tecan> will do
[11:03:02] <Tecan> not sure what im doing yet, just mapping out the land
[11:03:15] <Tecan> it'll be something cool im sure when its done
[11:03:20] <Tecan> whatever that is
[11:04:55] <awallin> ok. I'd like to build a telescope-mount, and perhaps a software-defined-radio. those could be based on mesa/fpga cards ? when/if I have time..
[11:06:39] <pcw_home> There will be some porting involved to use the HostMot2 source on a Cyclone (at the minimum the clock multipliers and SRL16s would need to be re-done in Altera compatible hardware)
[11:29:06] <Tecan> anyone here using modbus ?
[11:29:17] <JT-Shop> kinda
[11:29:32] <Tecan> for the interface controls ?
[11:29:43] <JT-Shop> for my VFD
[11:29:52] <Tecan> ah the spindle ?
[11:29:57] <JT-Shop> but it is a component so it is automagic
[11:32:48] <IchGuckLive> Hi B) ice 4cm on the road and 1cm on all trees covered
[11:33:49] <JT-Shop> yuck I dislike ice
[11:33:52] <pcw_home> nice dry winter Sunday here, going for a little hike with dog....
[11:35:42] <JT-Shop> not bad here, I have the shop door open so Woody can wander outside and tease the dog
[11:36:04] <IchGuckLive> O.O
[11:36:25] <IchGuckLive> woody woodpecker
[11:37:04] <JT-Shop> Woodrow aka Woody the cat that used to live in the wood pile and now guards the shop and garage from vermin
[11:37:12] <r00t4rd3d> http://www.yubico.com/products/yubikey-hardware/yubikey-nano/
[11:37:13] <Tecan> iirc modbus uses a networking card
[11:37:21] <r00t4rd3d> how google wants to replace using passwords
[11:37:27] <Tecan> and an adapter to db9
[11:37:42] <Tecan> or db9 to db9
[11:37:45] <pcw_home> dog knows somethings up so need to leave before he goes crazy in the house bbl
[11:39:08] <IchGuckLive> pcw_home: if you are able to do a video on how to get this plug and play 5i25+7i7x in good shape on the 2.6 with pnccond it woudt help so many asking here
[11:41:11] <Tecan> Modbus TCP/IP
[12:15:10] <IchGuckLive> B)
[12:51:19] <IchGuckLive> O.O
[13:14:02] <JesusAlos> can I change the default view of linuxcnc when start
[13:14:09] <JesusAlos> it ever prespective
[13:16:41] <Tecan> you can send Modbus/RTU encapsulated in TCP/IP or UDP/IP at 1Gbps or even 1 gazillion-billion bps.
[13:17:37] <Tecan> networking is done via card side rather than cpu right ?
[13:18:50] <archivist> cpu has to give it to the network card somehow (could be dma)
[13:19:12] <Tecan> hmmmm
[13:24:41] <archivist> and to see what the cpu cannot do while dma is occurring http://en.wikipedia.org/wiki/Direct_memory_access
[13:28:40] <pcw_home> AFAIK almost all network hardware access from modern PCs is via bus mastering PCI/PCIE devices
[13:30:02] <pcw_home> the MAC usually manages ring buffers in system memory
[13:30:39] <Tecan> interesting
[13:34:02] <archivist> all usually so fast it matters little till you see that a bus master device has stopped something else from happening and you start getting latency problems
[13:35:07] <Tecan> even at 1Gbps ?
[13:35:29] <pcw_home> Yes usually some hardware access will be blocked when the bus master has the bus
[13:35:57] <archivist> think how large a block is sent then see the real period
[13:37:06] <pcw_home> a 1500 byte packet on one lane PCIE is 6 usec minimum and about 12 on PCI
[13:38:49] <pcw_home> other hardware access may or may not be blocked during this time depending on specific system architechure
[13:45:23] <pcw_home> newer PCIE systems should be better as they will have per endpoint buffering and a higher root-CPU bandwidth
[13:50:42] <Loetmichel> hmmm, btw, pcw_home: do you know of any PCIe-LPTport-cards that act like isa cards? i.e with a 0x378 adress and so on?
[13:57:10] <JesusAlos> Please. I need change the gain of jog sped bar in linuxcnc
[13:57:26] <JesusAlos> my bar go from 0% to 900%
[13:57:34] <JesusAlos> I need 0% to 100%
[13:58:08] <JesusAlos> eny track?
[13:58:43] <jthornton> in Axis?
[13:59:06] <JesusAlos> yes
[13:59:12] <Tom_itx> under display isn't it?
[14:00:06] <jthornton> yea http://linuxcnc.org/docs/html/config/ini_config.html#_display_section_a_id_sub_display_section_a
[14:00:48] <JesusAlos> thank a lott
[14:19:11] <pcw_home> Loetmichel: I dont think so. (PCI/PCIe below 0x1000 is not allowed AFAIK)
[14:19:13] <pcw_home> PCI/PCIE Parallel cards usually work exactly like ISA cards except the base address
[14:20:22] <pcw_home> I should say PCI/PCIE I/O addresses below 0x1000 are not allowed
[14:20:52] <Loetmichel> pcw_home: i've seen PCI cards that utilize a PCI-ISA bridge and then an isa multi IO Chip
[14:21:07] <Loetmichel> i thought maybe they are aviable for PCIe, too?
[14:21:18] <Loetmichel> for old programs with fixed adresses
[14:22:29] <pcw_home> The problem is that most motherboards/chipsets will have a bridge for the local legacy I/O that will not allow PCI access below 0x1000 or so
[14:22:43] <pcw_home> (PCIE is the same)
[14:23:07] <Loetmichel> strange
[14:23:44] <Loetmichel> but if you say so... i could have sweared i've seen mainboards with multiple PCI-> isa bridges.
[14:23:54] <pcw_home> also with PCI/PCIE the BIOS sets the I/O address not the card
[14:24:00] <Loetmichel> never used the cards in legacy mainboards though
[14:24:35] <pcw_home> Its possible but less and less likely with newer MBs
[14:59:02] <mrsun> http://imagebin.org/index.php?mode=image&id=243519 45 degree holder for a grinder =)
[15:02:34] <mrsun> not the most beautiful piece of machinery but :P
[15:02:38] <mrsun> hopefully it will do its job =)
[16:27:36] <Tom_itx> what angle do i need to single point threads? is it 55 or 60?
[16:27:36] <Tom_itx> american fine thread
[16:28:27] <Jymmm> What does it take motor wise to make an electric car?
[16:28:51] <TekniQue> Tom_itx: afaik, american threads are 55 degrees
[16:29:25] <Tom_itx> Jymmm, a lego motor would do
[16:29:28] <TekniQue> Jymmm: 100 kilowatts is a good start
[16:29:31] <Tom_itx> geared properly
[16:29:41] <Tom_itx> you may not go very fast
[16:29:42] <Jymmm> seriously
[16:29:46] <Tom_itx> dead
[16:29:46] <TekniQue> I'd want at least 400 kilowatts
[16:29:55] <TekniQue> maybe four 100 kilowatt motors
[16:30:14] <Jymmm> I'm not talking tacing ot anything, just up to maybe 75MPH ?
[16:30:20] <Jymmm> *racing
[16:30:46] <Tom_itx> what did OCC put in their bike?
[16:30:55] <TekniQue> then you probably need about 50 kilowatts
[16:31:12] <Tom_itx> 25-50hp maybe
[16:31:25] <Jymmm> Ok, lets say 50KW, how much ?
[16:32:26] <Tom_itx> http://www.diyelectriccar.com/forums/showthread.php/looking-lightweight-motor-50kw-peak-60009.html
[16:32:41] <Tom_itx> According to Wikipedia, the Teslas motor weights only 32kg at a power of about 200kw
[16:33:35] <Jymmm> But how much? junkyard special?
[16:34:17] <Tom_itx> rental car special.. pull it out and call and tell them it quit on you
[16:34:55] <Jymmm> Tom_itx: huh?
[16:35:05] <Jymmm> ah
[16:36:00] <TekniQue> haha
[16:37:23] <Jymmm> I'm looking at getting a beater to get arund town, but might want to convert/play around after I get my SUV fixed
[16:37:45] <Jymmm> If I get a pre-1975, then it's smog exempt.
[16:38:56] <tjb1> r00t4rd3d: Did that guy ship your obd2 out yet?
[16:39:05] <Jymmm> I'm NOT lookng to put $20K into a project, but if I can play around and get junkyard specials on parts, I'd consider it
[16:40:15] <Tom_itx> so what old equipment used big electric motors you could salvage one from?
[16:40:31] <Jymmm> nfc, that's why I'm asking.
[16:40:37] <Tom_itx> trains
[16:41:08] * Tom_itx thinks a bit smaller...
[16:44:34] <DJ9DJ> gn8
[16:46:11] <r00t4rd3d> not yet, ordered it late friday so probably not till tomorrow
[16:46:51] <tjb1> Guy should have done some work and shipped them monday
[16:47:05] <tjb1> saturday…not monday

[17:01:25] <Jymmm> A panty dropper... http://sfbay.craigslist.org/sby/cto/3555994902.html
[17:01:58] <tjb1> 30-40 mile range…lol
[17:02:27] <tjb1> 0-20mph in 5 seconds
[17:03:02] <Jymmm> Yeah 1mph = 5s, +5s for +1mph
[17:03:30] <Jymmm> But electric does have serious torque
[17:03:53] <Jymmm> And enough room in the back for a 20gal tank and generator =)
[17:05:10] <tjb1> Kinda defeats the purpose of electric vehicle if you are going to use gas to charge it while dirver?
[17:05:11] <tjb1> driving
[17:05:39] <Jymmm> The "purpose" is to bypass smog requirements =)
[17:05:51] <tjb1> We dont have that here :)
[17:06:18] <tjb1> As long as everything appears to be there, you are fine
[17:06:19] <Jymmm> Commifornia even has emmissions on 5gal gas cans - seriously

[17:07:59] <tjb1> You know what I hate? the spillproof crap on the cans
[17:08:09] <Jymmm> That's the emissions shit
[17:08:48] <Jymmm> tjb1: BUT... the diesel/water ones do NOT have that
[17:09:04] <tjb1> they do around here
[17:09:11] <Jymmm> diesel/water/kerosene
[17:09:16] <tjb1> I dont know about water but the diesel ones do
[17:09:30] <Jymmm> Yellow/LtBlue/DkBlue/etc
[17:09:51] <Jymmm> ah
[17:10:12] <tjb1> Just causes more spills because you get pissed off and try to pour it without the spout
[17:10:15] <Jymmm> tjb1: Hit flea markets and yard sales
[17:10:42] <Jymmm> That's where I get/find mine whenever I can.
[17:10:51] <Jymmm> the Water lt blue doens't
[17:11:09] <tjb1> We have just been putting a screw through the can that you take out to use as a breather
[17:26:16] <Jymmm> these are two step latches.... slide, push, then dispense.
[17:27:43] <pcw_home> Jymmm why not a Via SUV its only ~$79,000
[17:28:38] <gene__> encoder.position = 0.0000 at power up with index pusle true, roll chuck to next index pulse, position says 1.282051 WTF????
[17:31:44] <gene__> put meter on counts, 1 turn=50, wheel supposedly hsas 39 slots
[17:33:39] <gene__> rol back to zero both track, must be time to dbl-check slot count of code that carved that wheel, or just set it for 50 in the .hal file, thats quicker
[17:35:40] <pcw_home> someone can't counr...
[17:35:46] <pcw_home> count
[17:37:37] <Jymmm> pcw_home: Sur,e if you can find a $80K for $1000, I'll take a look
[17:42:01] <gene__> I must have run out of toes too
[17:42:58] <gene__> if I had fresh metal in the chuck, I suspect the threads will be correct now too
[17:43:26] <gene__> But its time to go find me & Dee a nose bag, back later
[17:47:52] <s1dev> I can do CNC router stuff with LinuxCNC right?
[17:49:31] <L84Supper2> sldev: sure, lots of people do already
[17:50:38] <L84Supper2> s1dev: ^^
[17:51:59] <s1dev> I'm thinking about building a CNC router, any tips?
[17:53:11] <Jymmm> s1dev: Have a crap load of money
[17:53:35] <Jymmm> s1dev: And going cheap won't always be cheap in the long run
[17:53:40] <L84Supper2> oh oh Yahoo search results for linuxcnc returns LinuxCNC - Buy Adderall Online. No Prescription Needed.'
[17:53:47] <s1dev> lol
[17:54:09] <Jymmm> s1dev: (I'm not kidding btw)
[17:54:17] <AR_> he isnt wrong
[17:54:25] <L84Supper2> did the site get attacked again?
[17:54:33] <AR_> i started out with the intent to build a cnc mill under $200
[17:54:35] <AR_> LOOOOOOOOOOOL
[17:54:35] <Jymmm> L84Supper2: probably cached
[17:54:49] <AR_> i didn't even buy the frame yet and i'm over $500
[17:54:52] <s1dev> AR_ Jymmm the lol was at the adderall advert
[17:55:00] <Jymmm> ah
[17:55:22] <AR_> i need to spend about
[17:55:34] <AR_> well, at least $200 more
[17:55:48] <Jymmm> ...this week
[17:55:51] <AR_> to get the frame together, z axis assembly, and spindle control
[17:56:04] <AR_> shit no it will be over $200
[17:56:06] <s1dev> I should be able to make the frame out of steel right?
[17:56:25] <s1dev> I might be cutting some aluminum but that's all for metal
[17:56:39] <AR_> about $60 i need in aluminum plate for the z axis assembly and a couple other spots
[17:57:04] <L84Supper2> http://blog.ponoko.com/2011/07/15/pricing-guide-to-diy-cnc-mill-and-router-kits/
[17:57:05] <AR_> then the frame... if i win this ebay auction it will only cost about $100 total
[17:57:26] <L84Supper2> ^^ it's an older list but it gives you an idea
[17:57:31] <Tom_itx> how do you change the scale of an exploded view in a solidworks drawing?
[17:58:06] <AR_> yeah look at those pieces of junk that can only cut wood and plastics
[17:58:07] <mrsun> Tom_itx, http://www.goliath.com.au/tech%20thread%20forms.jpg
[17:58:11] <AR_> and they cost like $600
[17:58:20] <Jymmm> s1dev: The BEST advice you will ever get.... Plan EVERYTHING out before you spend ANY money. Draw up plans/diagrams, parts list, even down to the last washer before you buy anything. THEN, figure out what you REALLY want to do with it and if it's worth it.
[17:58:35] <s1dev> Jymmm thanks
[17:58:40] <AR_> micRo m3-kit $999
[17:58:40] <AR_> LOL
[17:58:43] <AR_> is that a joke?
[17:58:52] <AR_> i could make that for like $200
[17:59:29] <Jymmm> s1dev: Don't underestimate the nickle-and-dime-you-to-death for even hookup wire, unless you have a 4000sf+ "junk box"
[18:00:20] <AR_> they claim some of those machines can cut 'virtually anything'
[18:00:24] <AR_> wtf
[18:00:38] <AR_> then i should be able to cut ceramic on mine right?
[18:00:49] <AR_> at like 200ipm
[18:01:18] <AR_> you guys are getting me excited
[18:01:30] <AR_> gunna go press more 'buy it now' buttons
[18:01:32] <AR_> bbl
[18:02:04] <L84Supper2> depending on the ceramic, thickness, the tool, the spindle etc etc
[18:04:36] <AR_> Debits: -$556.34
[18:04:38] <AR_> fffffffffff
[18:05:21] <AR_> that is on the page of my checking account that is pretty much ONLY things i have purchased for my mill since christmas
[18:05:44] <AR_> when i'm finished and post pics, you will have to tell me how well i've done
[18:10:22] <AR_> http://i.imgur.com/6Saunms.jpg
[18:10:44] <toner> lol
[18:11:11] <Jymmm> AR_: You BOUGHT that ?
[18:11:30] <AR_> no rofl
[18:35:01] <L84Supper2> OT: wow, NFL football with the play by play in Mandarin... this very bizarre
[18:40:25] <s1dev> lol
[18:42:21] <s1dev> any thoughts on welding vs bolting together a frame?
[18:43:51] <Jymmm> OK, WTF.... What is the likelyhood of two differnt car mfg using the SAME PN for a "fuel pump" hyundai and ford.
[18:44:19] <Jymmm> same year veh too
[18:49:50] <L84Supper2> s1dev: bolting won't require the use of a welder
[18:50:46] <s1dev> and that's about it?
[18:51:06] <L84Supper2> bolt are usually easier to remove
[18:51:31] <L84Supper2> are you going to set it up and never move it?
[18:51:50] <L84Supper2> how good are your welds?
[18:52:22] <s1dev> good point
[18:55:26] <L84Supper2> s1dev: what size are you shooting for?
[19:00:09] <s1dev> L84Supper2: probably 3'x6'
[19:00:21] <s1dev> not sure about Z
[19:01:42] <L84Supper2> whats the going price of steel shapes per lb?
[19:03:02] <L84Supper2> we used to use non-spec steel pipe for budget projects like this
[19:03:58] <s1dev> I have no clue about steel prices right now
[19:04:27] <L84Supper2> we used to get it for just over the price of scrap
[19:05:01] <L84Supper2> it wasn't pressure tested or it didn't pass, but it was sched 40 or 80
[19:05:28] <L84Supper2> fine for frames or antenna masts etc etc
[19:17:24] <s1dev> L84Supper2 looking online I'm seeing a lot of designs that use aluminum extrusions, are they able to support the weight of a spindle well?
[19:18:22] <L84Supper2> s1dev: depends on the size,shape alloy of the extrusion and the mass and velocity of the spindle :)
[19:18:42] <L84Supper2> is a rock heavy?
[20:23:20] <r00t4rd3d> not the ones you be slingin
[20:46:09] <ReadError> r00t4rd3d, hows the wooden glock biz with the new NY gunlaws ?
[20:48:13] <r00t4rd3d> i was playing with a M4 model yesterday
[20:59:40] <s1dev> according to wikipedia dovetail slides are not ideal for high precision applications, why is that?
[21:02:40] <Tom_itx> wear
[21:03:02] <Tom_itx> air bearings are probably the best for precision
[21:03:25] <Tom_itx> the cmm we had used air bearings on the axis
[21:06:57] <s1dev> so is there a reason why dovetail bearings would be better than a railed shaft?
[21:08:33] <s1dev> *dovetail slides
[21:11:27] <s1dev> something like this seems perfect for the X axis of a CNC router http://www.mcmaster.com/#ball-bearing-carriages/=l4ihig
[21:11:39] <jdh> rigidity?
[21:12:20] <s1dev> wait, nevermind forgot to look at the price :P
[21:12:40] <Tom_itx> haha

[21:23:47] <r00t4rd3d> thats a good deal too
[21:33:07] <r00t4rd3d> supported rails are the easiest setup to go with
[21:38:32] <s1dev> would there be any concerns about a 3ft leadscrew?
[21:41:58] <Tom_itx> whipping around
[21:42:33] <Tom_itx> there are lots of them longer than that but probably 2 or 3" diameter
[21:42:37] <Tom_itx> or more
[21:47:15] <s1dev> what about a rack and pinion?
[21:51:43] <ReadError> i want a rack and pinion ;(
[21:52:32] <ReadError> everyone told me too much backlash

[21:56:21] <ReadError> s1dev, i want to build a router
[21:56:28] <ReadError> and rack & pinion sounds nice
[21:58:35] <s1dev> Tom_itx is it an aluminum extrusion or does it just mount to one?
[21:59:14] <Tom_itx> click on the 'products' tab
[21:59:40] <Tom_itx> and follow the SBL light duty link
[22:00:37] <Tom_itx> products -> linear positioning -> servobelt linear

[22:04:18] <r00t4rd3d> s1dev, I use a 3ft lead screw, only 3/8 too
[22:05:22] <s1dev> Tom_itx where do you buy it?
[22:05:49] <Tom_itx> i dunno
[22:05:56] <Tom_itx> look for a distributor list
[22:06:08] <Tom_itx> it looks pretty interesting to me
[22:07:36] <Tom_itx> http://www.bell-everman.com/sales-representatives
[22:07:37] <r00t4rd3d> u goto configure at the bottom
[22:07:49] <r00t4rd3d> and set your options then it will generate a quote
[22:08:44] <r00t4rd3d> which will probably be astronomical.
[22:11:04] <s1dev> yeah, that sort of thing looks like something they're charging $200+ per axis
[22:11:29] <r00t4rd3d> they want to stick it in your axis
[22:14:31] <Tom_itx> ff doesn't like their calculator
[22:19:41] <r00t4rd3d> I would hope companies who sell encoders would know how to code.
[22:23:38] <s1dev> would the backlash be significant on a rack and pinion systsem?
[22:31:30] <Tecan> what are hocky playoffs ? im an oilers fan
