[00:01:11] <tjtr33> there's 16 bit timers inside the SoftDMC.zip timer.vhd
[00:04:54] <tjtr33> i'm looking for this "Several pre-made functions are provided"... "a 8 channel, 32 bit timer counter card capable of running at 100 MHz." mentioned in the 5i20 manual
[00:21:27] <MattyMatt> uw apologies, I thought I was in #reprap. gcode is generated differently there
[00:30:21] <tjtr33> COUNTERS.VHD the 32 bit counter vhdl is in HOSTMOT not HOSTMOT2 ( i'm not yelling, the filenames are from dos i suppose)
[01:02:47] <pcw_home> Yes the Hostmot2 encoder counter is just 16 bits (top 16 bits of register is timestamp for velocity estimation)
[03:09:22] <DJ9DJ> moin
[04:44:56] <sadara> Couple of question, what is the best way to connect a resolver based servo to emc?
[04:49:54] <sadara> and I'm looking for a servo drive for a AC servo, but I'm having trouble understanding the datasheet
[04:53:06] <sadara> For the first question, I was concidering the Mesa 7I49 resolver card, but have no idea what I'm doing
[04:54:15] <sadara> From what I understand of the datasheet, the servos can be driving by anything up to about 230Vrms
[04:56:13] <sadara> link to datasheet http://www.electromate.com/db_support/downloads/APIBT171SERIES.pdf however I only have one of that size, the others I have are larger, PN BT-0232ERA-R1LN
[05:07:58] <Loetmichel> mornin'
[05:11:01] <sadara> evening
[05:21:40] <sadara> I take it noone here uses ballscrews?
[05:21:46] <sadara> sorry, servo
[05:22:39] <archivist> plenty do use servo
[05:23:16] <archivist> best people to answer you though wont be on till later
[05:23:39] <sadara> about what time, (Just asking cause it's 6pm here atm)
[05:25:05] <archivist> US day time and UK evening all depends who is around on the day
[05:26:02] <sadara> cool, thanks
[05:47:10] <cncbasher_> sadra: what type of machine .. or what servo drives do you have old or new ?

[06:47:28] <skunkworks> 7 deg F here this morning..
[06:47:44] <skunkworks> chilly
[06:54:14] <jthornton> we are supposed to get snow/sleet/ice this afternoon and tomorrow
[06:55:29] <skunkworks> yeck
[06:57:34] <jthornton> I might have time to find the lost screw and put the BlueWing back together...
[07:05:38] <cncbasher_> arh forget the screw use blutack
[07:07:46] <ReadError> makin quad frames cncbasher?
[07:09:21] <jthornton> I'm pretty sure the screw is not in the bike... I removed everything from the gas tank back that could harbor a screw sized object
[07:10:57] <cncbasher_> jt: you'l have lost it miles back when the Mrs Pulled it out and said whats this !
[07:11:38] <cncbasher_> u didnt reply so she thrown it
[07:12:02] <cncbasher_> ReadError: yea iv'e made a few
[07:12:56] <ReadError> thats what i use mine for too ;)
[07:12:58] <ReadError> any pics?
[07:13:45] <cncbasher_> actualy now u ask , no i dont think i have
[07:14:08] <cncbasher_> more interested in flying than pics haha
[07:23:38] <ReadError> cncbasher: this is what ive been making: https://dl.dropbox.com/u/25091878/Photo%20Mar%2007%2C%209%2014%2046%20PM.jpg
[07:24:04] <cncbasher_> hey thats neat
[07:24:34] <cncbasher_> is it acrylic your using ?
[07:24:40] <ReadError> g10
[07:25:05] <cncbasher_> yea look good
[07:25:40] <jthornton> cool quad
[07:26:49] <ReadError> http://www.youtube.com/watch?v=UQ3Lisz1PMc
[07:26:51] <ReadError> new machine
[07:27:47] <cncbasher_> i'm tempted to see if the laser will cut G10
[07:28:23] <cncbasher_> i now know why i dont use a router ! ,, the noise is terrific haha
[07:28:46] <ReadError> i got headphones and music to avoid that ;)
[07:30:43] <cncbasher_> i'm just working out the electronics side at the moment , figuring out which way to jump
[07:30:55] <ReadError> of the quad?
[07:31:22] <ReadError> i like the naze32
[07:36:51] <cncbasher_> dont think iv'e seen that one
[07:37:12] <cncbasher_> it's a few years since i last made some
[07:37:55] <cncbasher_> at the moment i need a test bench for some electronics
[07:38:18] <cncbasher_> so looking at building a more up to date quad
[07:38:50] <cncbasher_> last one i did was a meter between props
[07:39:57] <cncbasher_> but at the time the nav system was a bit noisy and started interfering
[07:40:44] <cncbasher_> so i pushed it to one side for a while , and just now resurecting it
[07:42:06] <jthornton> wow I just created a kml file with php
[07:53:29] <zenek> nick /micges_work
[07:54:12] * micges_work needs more coffee
[07:54:24] * skunkworks is brewing some
[07:58:23] <R2E4> too tired to get up and get some
[08:00:00] <archivist> hmm coffee time
[08:02:07] <Valen> bed time you fools its midnight
[08:03:39] * skunkworks has no problem drininking coffee before bed..
[08:04:27] <R2E4> ReadError: What material is that?
[08:11:37] <ReadError> R2E4: G10/Garolite
[08:43:24] <FinboySlick> L84Supper, pcw_home: I got this in my daily spam today: http://www.portwell.com/automation/ I didn't know Portwell went for automation.
[08:47:29] <L84Supper> http://www.portwell.com/products/IO.asp#DIGITAL_PCIPCI
[08:47:38] <AR__> wow
[08:48:10] <AR__> so i ordered a B&S Bestest DTI like 2 days ago and it will be delivered today
[08:48:19] <AR__> all the way across the country
[08:49:36] <AR__> and got it for $30
[08:58:45] <L84Supper> FinboySlick: they have made some interesting boards over the years http://www.portwell.com/products/Contec_IO.asp#Motor_Control is where they hide the motion control cards
[09:00:28] <L84Supper> the motion control boards use a motor control IC in the PCL6100 series from Nippon Pulse Motor Co., Ltd.,
[09:00:57] <L84Supper> http://www.npmt.com.tw/chip-pcl6100.htm
[09:01:01] <FinboySlick> L84Supper: Are those good?
[09:01:30] <FinboySlick> And I was mostly just wondering if they design the mobos these plug into with motion control in mind.
[09:01:39] <L84Supper> http://www.npmt.com.tw/basic-specifications-pcl-pcd.htm
[09:01:55] <L84Supper> they are just PCI based, they will work in any PCI MB
[09:03:09] <FinboySlick> L84Supper: I meant the pre-built motion control computers that were in my initial link, not the motion control cards themselves.
[09:03:44] <FinboySlick> They mention windows so I assume they aren't really caring about realtime performance of the OS.
[09:04:22] <L84Supper> http://www.portwell.com/automation/ this link? These are just rack mount systems with a ATX MB and PCI cards
[09:05:11] <L84Supper> i haven't seen any linux support for the PCL6100 series
[09:05:31] <L84Supper> http://www.npmt.com.tw/basic-specifications-pcl-pcd.htm
[09:06:02] <L84Supper> http://www.npmt.com.tw/explanation-functions.htm
[09:07:18] <L84Supper> http://www.npmt.com.tw/motionnet.htm
[09:09:01] <L84Supper> http://www.npmt.com.tw/download/Motionnet/Introduction%20of%20Motionnet.pdf
[09:10:06] <L84Supper> they have their own shop floor bus, but only drivers for win2K, XP and DOS
[09:10:58] <L84Supper> hehe, yet their data sheet is titled "Substantial User Software"
[09:12:35] <jdh> if I have a 24mm OD bearing. How big should the bearing holder be?
[09:13:13] <L84Supper> jdh: what material for the holder?
[09:13:33] <jdh> 6061 for the prototype, tool steel for the final version
[09:13:33] <AR__> make it 23.5mm and press fit
[09:14:01] <cpresser_> it also depends on which kind of OD that 24mm is
[09:14:15] <cpresser_> i have books an tables for 'fits' (http://de.wikipedia.org/wiki/Passung)
[09:14:30] <L84Supper> 0.5mm interference fit!? does he have a large press?
[09:14:49] <jdh> I have a 12? ton press
[09:14:50] <AR__> yes
[09:14:51] <cradek> yeah I don't think that was meant as actual advice
[09:15:03] <jdh> but, that seems excessive for a bearing.
[09:15:57] <L84Supper> jdh: what type of load is the bearing going to experience?
[09:16:13] <cpresser_> most likeley the bearging is "24h7" which indicates its maximimum diameter is 24mm, its minimum is 24mm-0.021mm
[09:16:44] <cpresser_> the bore as 24H7 is 24mm+0.021mm
[09:17:03] <cpresser_> which gives you a transition-fit
[09:17:06] <L84Supper> any axial forces?
[09:17:23] <AR__> ok so then at most 23.9mm
[09:17:52] <archivist_herron> press fit is .001 " per inch of diameter as a rule of thumb
[09:17:59] <cradek> I'd guess more like 23.95 (.03-.05 interference)
[09:18:14] <L84Supper> that sounds about right
[09:18:32] <cpresser_> http://www.pfeffer.ch/toleranzen.htm (unfortunately i lack the language skills to find an english page)
[09:18:42] <cradek> in Al anyway. for steel you might want it bigger?
[09:18:43] <archivist_herron> but is the bearing designed for press fit or sliding fit
[09:18:57] <AR__> archivist_herron, so a 1" OD will press fit into a .999" ID?
[09:19:03] <cradek> it's true, the bearing manufacturer's opinion would be better than all of ours
[09:19:05] <archivist_herron> the clearance of the balls is different
[09:19:47] <L84Supper> will the axial forces want to push or pull the bearing from the holder?
[09:20:00] <AR__> yes
[09:20:23] <cpresser_> check "DIN ISO 286-1"
[09:20:24] <cradek> I've definitely had bearings get "tight feeling" when press-fit
[09:20:36] <cradek> I assume that means I did it wrong
[09:21:02] <AR__> pre-load
[09:21:21] <archivist_herron> SKF bearing book/catalogue has a lot of advice
[09:21:43] <cpresser_> http://files.engineering.com/download.aspx?folder=441ec3ff-d975-49be-8432-8d3051b8436a&file=ISO_286-1-2010.pdf
[09:22:33] <L84Supper> depends on how tight, ever work on auto wheel bearings? you often tighten and then measure preload
[09:23:16] <L84Supper> FinboySlick: http://www.npmt.com.tw/download/PCL%20SeriesPCD%20Series/PCL6000%20series/PCL6046%284-axis%29/PCL6046_User%27s_manual090807.pdf with register specs, not sure how complete though
[09:26:24] <FinboySlick> L84Supper: Most of this is a bit over my head. This was more about the potential for a good, relatively powerful mobo for LinuxCNC, assuming that Portwell would design the motherboard with system latency in mind.
[09:28:51] <L84Supper> FinboySlick: nah, just standard stuff with Phoenix or similar BIOS
[09:29:11] <L84Supper> I've talked about coreboot with them before
[09:32:01] <FinboySlick> L84Supper: Is coreboot affected by the spread of UEFI? I'm thinking that since they tend to be much larger, it would mean more room on the typical motherboard bios chip, but then there's secureboot too.
[09:33:14] <L84Supper> FinboySlick: we used to cram coreboot in 256KB of flash so 1-2MB is enough for coreboot + Linux kernel
[09:33:57] <FinboySlick> In many boards, it's 32Mbit/4MB now.
[09:47:28] <L84Supper> FinboySlick: the Mesa boards use FPGA's so the hardware may be customized, the Portwell boards use an ASIC that only lets you modify register settings
[09:48:37] <L84Supper> need some extra counters of some IO for something specific, it's not a problem with Mesa, with portwell you might have to add another board or add an FGPA card to do the same thing
[09:49:03] <FinboySlick> L84Supper: I'm definitely keener on mesa, though it's a bit moot with my mill. I can already drive it faster than its rigidity allows for accurate parts.
[09:51:30] <L84Supper> I need a transporter so I can move equipment around the world faster..... already working on the replicator.... anyone free?
[09:52:53] <cncinator> did you tried it wth a catapult?
[09:53:51] <FinboySlick> Actually, the CIA killed a canadian dude who could have helped with that when he tried to sell his design to Saddam ;)
[09:54:43] <FinboySlick> Because when you build a gun that can put satellites in orbit, it's best not to sell it to a despot.
[09:55:17] <cncinator> are there any formal requirments for shooting sattelites in the orbit?
[09:55:51] <FinboySlick> cncbasher: I think you have to be good at math ;)
[09:56:01] <L84Supper> in the US there is
[09:56:08] <cncinator> im not basher ^^
[09:56:10] <L84Supper> not sure about Canada
[09:57:28] <cncinator> lets say we start our rocket with a simple sattelite onboard at sea
[09:57:28] <skunkworks> cncinator, did you get a better video ;)
[09:58:03] <cncinator> skunkworks, i crashed yesterday - have to recalibrate evry fuckin tool befor i can go on :(
[09:58:16] <skunkworks> ouch
[09:58:25] <skunkworks> what was the malfunction?
[09:58:34] <cncinator> G0 ^
[09:58:36] <cncinator> ^^
[09:58:44] <FinboySlick> cncinator: Sorry about that, tab error.
[10:00:04] <skunkworks> I once inverted X and Z... Sheared a 3/4 inch aluminum shaft right off..
[10:00:31] <cncinator> turned OD with a ID tool, then i g0X instead of g0Z and my lathe turret moved about 5degree
[10:01:00] <cncinator> thats wasted time, sad
[10:01:06] <skunkworks> yep
[10:03:08] <cncinator> guess ill have to buy a keychain-cam and mount it to the turret for some videos, my android sucks hard on it :(
[10:09:50] <cncinator> http://www.ebay.de/itm/Mini-808-Car-Key-Chain-Hidden-Camera-Digital-Video-Recorder-Card-New-720-x-480-/300630138086?clk_rvr_id=460861934474
[10:10:37] <cncinator> i allready owned one of these, did great videos, usb mode, webcam etc
[10:44:28] <L84Supper> cncinator: do you use that in Germany?
[10:46:32] <cncinator> i live in austria, why?
[10:48:26] <L84Supper> cncinator: privacy laws, some are tougher there than in the US
[10:49:31] <cncinator> same in europe, but for taking videos in my toolshed i wont get locked away
[10:50:22] <skunkworks> Says you! ;)
[10:50:31] <cncinator> xD
[10:51:03] <Err> depends on who's in the toolshed with you :-)
[10:51:16] <cncinator> in europe, mainly mid europe you wont visit the jail that fast as in the us
[10:51:52] <cncinator> yes, ofc - just check if they hit 16 :>
[10:52:48] <Err> heh
[10:54:39] <FinboySlick> cncinator: I wouldn't put it past the EU to pass laws on toolshed privacy.
[10:55:15] <Err> heh, I'm totally down with privacy laws - we could all use a little more
[10:56:47] <L84Supper> it becomes more problematic to run a police state when you have privacy laws, at least on the surface
[10:56:56] <cncinator> noone will denounce you for owning a spy cam, they may denounce you for what youre doing with it
[10:57:28] <L84Supper> nothing painful I hope :)
[10:58:53] <cncinator> in europe, law needs to evince that youre guilty
[10:59:34] <cncinator> and as harddiskdrives of really bad/mad people are crypted, law cant do a **** on those people
[10:59:48] <R2E4> Is the logic for the flooding and coolant usually done with LinuxCNC and interfaced with relays?
[11:02:24] <pcw_home> M7,M8,M9 and Relays or SSRs
[11:13:58] <R2E4> thanks
[11:18:37] <IchGuckLive> hi all B)
[11:42:49] <IchGuckLive> by till 19:00 MEZ
[12:25:04] <Loetmichel> re @ home
[12:30:34] <FinboySlick> L84Supper: I was watching a few youtubes of people attempting to recylce HD heads into laser galvanometers last night.
[12:34:19] <Loetmichel> FinboySlick: hmmm
[12:34:26] <Loetmichel> WAY to much mass
[12:34:33] <Loetmichel> -> to slow ;-)
[12:34:55] <FinboySlick> Loetmichel: I agree, though for a ghetto laser show, it'd probably still work.
[12:35:10] <FinboySlick> IF you get rid of the actual head and just use the actuator, which is usually plastic.
[12:35:19] <Loetmichel> with lissajous figures: maybe
[12:35:38] <Loetmichel> with anything "drawn" with right angles: no ;-)
[12:36:54] <Loetmichel> FinboySlick: the acuator sits usually on a 1/4" or bigger shaft with two ball bearings
[12:37:12] <FinboySlick> Do they make piezo-actuated galvanometer? For a set scan rate, I'd assume those would be very fast.
[12:37:21] <Loetmichel> that alone has to much mass for anything abpve a few kHz ;-)
[12:37:45] <FinboySlick> They'd have to be very small to get any meaningful angle.
[12:38:09] <Loetmichel> not necessarily
[12:38:14] <Loetmichel> man piezo stack
[12:38:55] <FinboySlick> There'd be a mass advantage to make them small too though.
[12:39:47] <Loetmichel> thats right
[12:39:53] <FinboySlick> I imagine that this is how DLP works, piezo-actuated mirrors.
[12:40:07] <Loetmichel> but jou have to stay bigger than the laser dot ;-)
[12:40:30] <L84Supper> yeah, they make piezo galvo type mirrors
[12:41:42] <Loetmichel> right, dlp = masses of VERY tiny piezo mirrors on a SI-bed
[12:43:58] <L84Supper> http://www.physikinstrumente.com/en/products/prdetail.php?sortnr=300710 $8K heh
[12:55:11] <pcw_home> DLPs are electrostatic
[12:59:21] <L84Supper> http://www.ti.com/lit/an/dlpa008/dlpa008.pdf TI's DMD paper
[13:01:07] <pcw_home> I have a couple DLP chips around here, interesting under the microscope
[13:01:59] <L84Supper> TI was awarded a very broad patent on the tech, they are going to have a fit when they get bypassed by better tech
[13:03:28] <pcw_home> aren't laser projectors supplanting these anyway?
[13:04:21] <L84Supper> http://www.youtube.com/watch?v=gF4HG6v29UY Casio Laser projector burns some stuff
[13:04:59] <pcw_home> I looked a little at white led on/off times and may are quite fast so 1 Usec pulses are possible (With some yellow tailing)
[13:05:04] <IchGuckLive> the co2 lasers got belw 400USD so it will be part of time to be CNC stufff
[13:05:15] <pcw_home> s/may/many/
[13:05:58] <L84Supper> high power LED prices are dropping like rocks
[13:06:03] <pcw_home> so a 100W (about $22) white LED might be a pretty decent strobe down to 1 usec or so
[13:06:21] <pcw_home> blue is good to 10 nS or so
[13:06:59] <L84Supper> 2 months ago I paid $30 for a 1w 405nm, yesterday I paid $3
[13:07:01] <IchGuckLive> the 100W china Neodyn lasers are also afortable
[13:07:04] <pcw_home> (assumin you have a decent driver)
[13:08:54] <pcw_home> Dont know about the white ones, but you can overdrive about 5X current for short duty cycles and get maybe 3X flux
[13:09:06] <pcw_home> (on blue)
[13:09:54] <L84Supper> it's however you can cool them is pretty much the limiting factor
[13:10:04] <pcw_home> No need
[13:10:32] <pcw_home> were talking 1% or lower duty cycles
[13:10:54] <L84Supper> I was commenting on CW
[13:11:00] <pcw_home> (strobe usage)
[13:11:39] <IchGuckLive> diode from Pinoeer BDR-205BK (12x)
[13:11:44] <IchGuckLive> 580W
[13:11:47] <IchGuckLive> mW
[13:12:12] <IchGuckLive> that gives you a good start for burning down the house
[13:13:46] <L84Supper> http://www.microvision.com/technology/picop.html
[13:14:37] <L84Supper> http://stks.freshpatents.com/MVIS-sym.php
[13:16:19] <pcw_home> Jeez theres got to be prior art for lissajous scanners from the 30s
[13:16:46] <L84Supper> doesn't stop a patent anymore
[13:17:16] <L84Supper> they just file and many get approved with the attitude to let the courts sort it out
[13:18:19] <IchGuckLive> pcw_home: is a modern PC cooler enoph to cool a 100W LED
[13:20:17] <pcw_home> I think so , that seems to be what people use
[13:21:06] <IchGuckLive> 35V is pretty high at 3.5A
[13:23:29] <pcw_home> well that 100W in, not sure what the luminous efficiency is by most of that winds up as heat
[13:23:30] <IchGuckLive> tjb?
[13:24:51] <FinboySlick> http://www.lemoptix.com/technology/innovation/scanning-micromirror That's a pretty cool little chip.
[13:25:21] <IchGuckLive> we will see a change in techiks on lightning
[13:25:33] <IchGuckLive> as the tecnologia chenges
[13:26:11] <IchGuckLive> if the US get all there monster Fresers of it will be drop at 40% in power request
[13:26:44] <IchGuckLive> ice mashines and aircooler drops that 2 65%
[13:27:18] <IchGuckLive> so the south states wil get solar powerd up to 95%
[13:28:13] <pcw_home> FinboySlick: a couple of those and a blue laser would make a nice photo-polymer 3d setup
[13:28:25] <andypugh> FinboySlick: They don't show it, but I think that a gymbal-style arrangment ought to allow 2D scannning?
[13:30:12] <FinboySlick> pcw_home: That's exactly what I was thinking. I wonder if they make fpga big enough to store a decent frame buffer. Two chips, one fpga and a laser gets you a complete setup you can just push slices to.
[13:31:02] <pcw_home> My dentist gave me a bit of the tooth repair photopolymer to hold in my hand while he hardened it with the blue LED
[13:31:04] <pcw_home> Amazingly fast transition from putty to rock
[13:31:37] <pcw_home> Probably only need a line buffer
[13:31:45] <pcw_home> and thats easy
[13:33:49] <FinboySlick> pcw_home: Their picoprojector uses a x/y mirror too.
[13:40:54] <cncinator> can someone tell me why all my tools are 0,25mm off?
[13:41:16] <cncinator> no fixture loaded and 3 times referenced
[13:41:40] <IchGuckLive> G92 in place ?
[13:41:45] <cncinator> nope
[13:41:59] <IchGuckLive> did you check the parameters
[13:42:12] <IchGuckLive> in the parameter file
[13:42:24] <IchGuckLive> Backlash ?
[13:43:12] <cncinator> it worked fine, had a 15min programm running, then i switched the workpiece side to machine the other end and now all tools are exactly 0.25mm off..
[13:44:10] <IchGuckLive> did you use the same corner for touching
[13:44:19] <IchGuckLive> corner is straight
[13:44:26] <cncinator> lathe?
[13:44:58] <IchGuckLive> im out 1
[13:45:09] <IchGuckLive> no idee
[13:49:06] <cncinator> -.-
[13:53:02] <cncinator> jesus why
[13:53:14] <cncinator> the complete tooltable
[13:53:16] <cncinator> wasted
[13:54:44] <IchGuckLive> did you use G41/42 40
[13:54:53] <cncinator> no
[13:55:09] <cncinator> just g95, g43
[13:55:13] <IchGuckLive> did you reset all cycles
[13:55:45] <IchGuckLive> G49 resets g43
[13:57:25] <cncinator> yes, evrything reseted, restarted, referenced - 0,25 off
[13:57:49] <IchGuckLive> then your switch fails
[13:58:11] <cncinator> i didnt used it between the 2 programms
[13:58:18] <cpresser_> or you lost steps
[13:58:44] <cpresser_> mechanical failure is also possible
[13:58:48] <cncinator> even after referencing?
[14:00:17] <cpresser_> sure. just imaginge: 1. reference 2. machine stuff and lose steps 3. reference again 4. error
[14:00:32] <IchGuckLive> for checking use a dial on Z Max position
[14:00:47] <IchGuckLive> go fo No part
[14:00:51] <IchGuckLive> and max speed
[14:01:06] <IchGuckLive> go then G53 to the dial and see
[14:02:06] <IchGuckLive> cncinator: your Z ref is at max Z HOME is ?
[14:02:28] <cncinator> no its the x axis
[14:02:36] <cncinator> with seperate home and limit switch
[14:02:58] <IchGuckLive> Diameter or radius mode
[14:03:05] <cncinator> g7 diameter
[14:03:31] <IchGuckLive> the ref switch on X is max positive
[14:03:43] <IchGuckLive> or even close
[14:04:22] <cncinator> ref is at 35
[14:04:26] <cncinator> soft max 55
[14:04:34] <cncinator> switch min 0
[14:05:04] <IchGuckLive> the Ref switch position is at Home_offset what is this value in the ini for X
[14:05:45] <cncinator> the same a reference
[14:05:47] <IchGuckLive> do you got a dial
[14:05:50] <cncinator> yes
[14:05:55] <cncinator> allready testing movement
[14:06:36] <IchGuckLive> with the G53 value
[14:06:46] <cncinator> it references to 0 and gives no misspositioning with g0 in 0,5mm steps
[14:06:48] <IchGuckLive> no tool
[14:07:40] <andypugh> Chipped tool? Radius compensation?
[14:07:42] <IchGuckLive> i woudt go to far X plus end and set the dial on a G53 number there to Zero
[14:08:19] <IchGuckLive> lets say G53 X50
[14:08:41] <IchGuckLive> dial is zero there now run the programm 2 times no tool
[14:09:14] <IchGuckLive> and get MDI G53 G1 X50 Fxxx
[14:09:26] <IchGuckLive> and see if it is still there
[14:09:35] <IchGuckLive> then your mashine is ok
[14:11:09] <cncinator> it matches with reference position
[14:11:46] <IchGuckLive> reference both way or only one
[14:12:10] <IchGuckLive> i woudt not check on reference
[14:12:19] <IchGuckLive> toolpath
[14:12:26] <JT-Shop> crap I need to cut something on the plasma and the computer won't come on...
[14:12:36] <IchGuckLive> BAD
[14:12:46] <IchGuckLive> JT-Shop: go for manuell
[14:14:10] <IchGuckLive> JT-Shop: im to far away to give you a hand 7-8k/Km
[14:14:18] <IchGuckLive> B) O.O
[14:16:23] <JT-Shop> yea, the fan on the power supply works... so I'll work my way from there
[14:16:47] <IchGuckLive> no piep is bad
[14:17:01] <IchGuckLive> how many water it took last plasma cut
[14:17:03] <JT-Shop> no peep at all
[14:17:42] <IchGuckLive> RAM remove
[14:17:57] <IchGuckLive> and the Graphics if not onboard
[14:18:21] <IchGuckLive> cr2032 out
[14:18:36] <JT-Shop> 525 mother board
[14:18:47] <IchGuckLive> BAD
[14:19:54] <IchGuckLive> to hot after shutdown
[14:27:16] <JT-Shop> hmmm
[14:27:27] <IchGuckLive> seams only underpowering
[14:27:52] <IchGuckLive> there is noone having trouble with this board
[14:28:03] <IchGuckLive> on boot failue
[14:29:47] <JT-Shop> I have 5v and 12v on the peripheral connector
[14:30:10] <JT-Shop> I think I have another motherboard with a dead lan
[14:31:09] <IchGuckLive> im off
[14:31:27] <L84Supper> FinboySlick: the plan is to be able to cheaply print devices like that real soon using a 3D printer
[14:33:30] <L84Supper> http://www.picop.org/
[14:36:44] <fragalot> not sure which part of that you think you could print cheaply
[14:37:07] <fragalot> it barely has any structural plastic parts in it as far as I can tell
[14:37:23] <L84Supper> the mems mirror
[14:38:06] <L84Supper> I hope you don't think I'm talking about using a reprap
[14:38:25] <fragalot> lol no, I have one and it's good for printing quick rough things but that's about it
[14:38:40] <fragalot> never heard of anyone printing mirrors though
[14:39:07] <L84Supper> just starting to print devices
[14:39:17] <fragalot> Neat :)
[14:39:31] <L84Supper> multiple materials with submicron features
[14:43:43] <L84Supper> http://tinyurl.com/chevv7n looks like s good deal, the retrofit probably cost more than they are asking
[14:47:51] * fragalot snipes
[15:05:45] <JT-Shop> as soon as I get those parts cut out I'm ordering a couple of those motherboards that pcw_home found when I can find the number
[15:09:05] <FinboySlick> L84Supper: What an adorable big beast.
[15:09:15] <tjb1> I just got an email from Hardinge, they want me to tour the plant. All traveling expenses paid :)
[15:10:58] <R2E4_> Anyone see a problem if I provide a 20Amp 220Volt circuit for the electronics of a bridgeport and a seperate 10amp 220volt circuit for the spindle?
[15:11:09] <R2E4_> 12 guage both?
[15:13:02] <FinboySlick> tjb1: You think you can put a GX 250 on your expense report? ;)
[15:13:29] <tjb1> FinboySlick: Ha I don't think so
[15:13:52] <FinboySlick> tjb1: You should... You never know when a joke gets taken seriously.
[15:16:13] <JT-Shop> tjb1: nice!
[15:17:49] <tjb1> FinboySlick: I'm trying to get a job there!
[15:18:21] <tjb1> I might be able to work at Prototrak too but that would require going to California
[15:18:27] <FinboySlick> tjb1: Even better, make it part of your sign-up bonus.
[15:18:42] <tjb1> FinboySlick: They pay for the moving trucks and first month rent ;)
[15:19:14] <FinboySlick> tjb1: Well, they can put it on the truck!
[15:19:20] <FinboySlick> Think positive, dude.
[15:19:28] <tjb1> I don't like motorcycles
[15:19:31] <tjb1> Deadly things
[15:19:57] <tjb1> Well not the motorcycles, just all the idiots you have to drive around
[15:32:19] <L84Supper> R2E4_: no problem with that
[15:32:57] <L84Supper> 12ga is rated for 20A with 3 or less conductors in a conduit
[15:41:46] <R2E4_> thats what I thought. Thanks.
[15:44:08] <L84Supper> http://tinyurl.com/d7g4c4f here's a monster bargain
[15:44:47] <FinboySlick> L84Supper: Doesn't look rigid enough, you'd probably need to brace it ;)
[15:45:17] <L84Supper> nothing a trip to the hardware store and some 2x4's can't fix
[15:45:29] <FinboySlick> Hehe, what a beast.

[15:48:02] <FinboySlick> Probably needs a bit more TLC though.
[15:50:18] <tjtr33> recent user list emails about linuxcncrsh got me to install man2html & swish++,
[15:50:19] <tjtr33> now i have bookmarks for items like http://localhost/cgi-bin/man/man2html?query=linuxcncrsh
[15:50:34] <tjtr33> no more extra terminals
[15:51:48] <cradek> you've replaced the occasional invocation of nroff with a web server that runs all the time? is there an sql database for some reason too?
[15:51:58] <cradek> (sorry)
[15:52:46] <JT-Shop> I just had a file that had an error while in a G92 offset. The dro reads -1.23 for X but G0 X0 won't make it go to the G92 X0 point
[15:54:16] <tjb1> What is the dress code for a plant tour?
[15:58:48] <r00t4rd3d> toga
[16:01:09] <tjtr33> cradek, i had to look up the relationship of nroff to man to understanf that comment was for me :), i dont see a big diff in load or memory use.
[16:02:44] <tjtr33> cradek, i think it only runs while i open the port and have my browser running ( ffox 19.0)

[16:18:53] <cradek> bullets are trivially easy to cast
[16:19:08] <TekniQue> yeah
[16:19:16] <TekniQue> lead is the easiest metal in the world to cast
[16:19:29] <L84Supper> not technical problem, social problem
[16:19:31] <cradek> making new primers, not so easy
[16:20:02] <cradek> if crazy irrational fear of gun-taking-away causes advances in 3d printing, yay, I guess
[16:20:25] <cradek> we don't get much new technology (for the people) from our wars anymore
[16:22:21] <r00t4rd3d> http://chrome.com/maze/
[16:22:24] <r00t4rd3d> that is cool
[16:24:37] <cradek> it's spring!
[16:25:39] <JT-Shop> now I'm really confused the part came out big on X but spot on in Y
[16:28:51] <tjb1> Late to the party r00t4rd3d
[16:35:47] <JT-Shop> second try came out perfect
[16:38:31] <r00t4rd3d> tjb1, i should be able to cut aluminum decently now
[16:38:46] <tjb1> ok
[16:38:58] <r00t4rd3d> i redid my z axis with linear carriages
[16:40:29] <r00t4rd3d> i need to bumb my x axis screw up to 1/2 from 3/8 still though
[17:00:55] <tjb1> up from 1/2 to 3/8?
[17:01:08] <tjb1> oh nevermind
[17:01:12] <tjb1> to 1/2 from 3/8
[17:12:10] <tjb1> JT-Shop: Plasma problem?
[17:13:01] <JT-Shop> some kind of problem... I got an error then I fixed that and ran the part and the X was scaled up a tad somehow
[17:13:07] <JT-Shop> weird
[17:14:19] <tjb1> linux error or cutter?
[17:16:07] <JT-Shop> linux
[17:16:36] <JT-Shop> I flipped the sheet over and ran the same file again and perfect

[17:58:17] <gmag> hi
[17:58:38] <zenek_> hi
[17:58:49] <gmag> :)
[17:59:40] <gmag> I wonder how much a cork extrusion machine would cost... any idea? (certainly offtopic)
[18:01:27] <gmag> if I can't get an answer in this channel, I won't get it anywhere in freenode :) I had to try here
[18:01:44] <gmag> you guys rock in machinery
[18:04:09] <L84Supper> extruder made of cork or extrudes cork?
[18:05:30] <L84Supper> gmag: synthetic cork?
[18:10:17] <r00t4rd3d> #reprap might know
[18:13:32] <gmag> L84Supper, machine that extrudes cork. Natural cork
[18:14:59] <gmag> L84Supper, but if you know of any reference please share. I just want to get an idea of how much I would pay for one of those machines
[18:15:02] <Tom_itx> you sure it's extruded?
[18:15:09] <Tom_itx> kinda have my doubts
[18:15:15] <gmag> Tom_itx, what do you mean
[18:15:24] <gmag> the cork is extruded
[18:16:20] <gmag> to make stoppers are made by extrusion
[18:16:35] <cpresser_> i dont understand how it would work. cork itself has no cohesion
[18:17:07] <gmag> cpresser_, they mix other stuff
[18:17:27] <gmag> stoppers are not made of pure cork
[18:17:50] <gmag> there's silicon and paraffin
[18:18:36] <gmag> cork is baked, mixed with these other "ingredients" and then extruded
[18:18:40] <cpresser_> are you sure its free-form extruded? i would rather guess it gets molded
[18:22:58] <gmag> cpresser_, that stopper you're thinking about is a very expensive one
[18:23:07] <gmag> you dont see it often
[18:23:18] <gmag> a pure cork stopper is vary rare
[18:23:34] <cpresser_> pictures?
[18:23:44] <gmag> http://www.youtube.com/watch?v=ETsl-TiLowI
[18:24:04] <gmag> this video shows those expensive stoppers being made
[18:25:03] <cpresser_> i dont think so. they show cork for wine bottles
[18:25:45] <gmag> http://www.cork.pt/agglomerated-cork-stoppers.html
[18:25:56] <gmag> a reference is made to cork extrusion there
[18:27:41] <cpresser_> yes. LINEAR extrusion
[18:27:57] <cpresser_> for cylindrical shapes
[18:28:15] <gmag> exacly
[18:28:55] <gmag> any idea of the price of one of these machines? Probably the price would be the same of a plastic extruder (??)
[18:29:35] <cpresser_> i dont think you can buy them off the shelf
[18:29:54] <Tom_itx> JT-Shop could build you one
[18:30:03] <cpresser_> most likely they are custom made.
[18:30:34] <gmag> JT-Shop? :)
[18:30:37] <gmag> what's that?
[18:30:51] <gmag> jthornton shop?
[18:32:08] <gmag> cpresser_, you're probably right
[18:33:02] <gmag> cpresser_, I'd like to make one of these machines. But I dont have expertise to do it.
[18:33:46] <gmag> I was able to make a desktop CNC and I would say 90% of it I got from LinuxCNC :)
[18:33:49] <L84Supper> a plastic extruder for something 20mm dia would sell for >$125K that extrudes ~80Kg/hour
[18:33:59] <gmag> considering the software 90% of the cnc of course...
[18:34:23] <cpresser_> since it wont require heating (at least i guess so), you could use a kitchen extuder (for meat grinding or sausages)
[18:35:10] <JT-Shop> Tom_itx: what?
[18:35:16] <cpresser_> do you want to tinker with it, or go big?
[18:35:36] <Tom_itx> JT-Shop, i told him you'd volunteer to make him a cork extruder :D
[18:36:06] <L84Supper> where was that link to the big dc motor and gearbox?
[18:36:52] <L84Supper> http://racine.craigslist.org/bfs/3693598309.html that will save you ~$15K
[18:37:21] <gmag> L84Supper, registered, good to know that
[18:37:28] <JT-Shop> for a wine bottle?
[18:37:36] <Tom_itx> apparently
[18:38:16] <gmag> JT-Shop, yeah
[18:39:00] <gmag> I'm seriously thinknig in making one or ask someone to make one
[18:39:04] <L84Supper> http://www.ebay.com/itm/4-5-PLASTIC-EXTRUDER-by-STERLING-/300868830549?pt=LH_DefaultDomain_0&hash=item460d2e0555

[18:40:06] <L84Supper> RUNNING HDPE: 700 LBS/HR
[18:40:19] <L84Supper> how many corks do you need a hour?
[18:40:52] <L84Supper> a plastic extruder won't work with actual cork from a tree
[18:41:34] <L84Supper> but this gives you an idea of the size motor and screw you'll be looking at to move material
[18:42:40] <gmag> L84Supper, 2 meters per hour should be ok
[18:43:24] <L84Supper> somebody must make a barrel screw design for cork composite
[18:43:56] <L84Supper> in fact it might not even be a screw, more of a piston and cylinder
[18:45:35] <cpresser_> gmag: http://fehrmann.de/bilder/fleischereimaschinen/fleischereimaschinen-wurstmaschine.jpg
[18:45:59] <cpresser_> those are used for sausages; a few of them use a piston
[18:46:11] <cpresser_> i guess those are less then 10k$
[18:47:13] <gmag> cpresser_, quite interesting!!

[18:47:32] <L84Supper> US $1,200.00
[18:49:45] <cpresser_> but be carefull, some of them use a rotary-vane pump for transport
[18:49:54] <gmag> yeah, that's what I call thinking out of the box. My mind was focused on cork only... silly of me
[18:50:08] <cpresser_> i dont think that those designs can deliver enought pressure
[18:50:29] <Tom_itx> me either
[18:51:01] <L84Supper> the patent drawings on cork extruders just look more heavy duty
[18:51:21] <gmag> L84Supper, patent drwaings? Where
[18:51:36] <L84Supper> look up cork extruders
[18:51:42] <gmag> yup
[18:51:43] <gmag> found it
[18:54:54] <JT-Shop> PCW: are you around?
[18:55:08] <gmag> wow lot of information, thanks a lot. I have a lot to read before
[18:55:27] <gmag> before deciding what to do
[18:55:45] <JT-Shop> anyone remember the model number of that motherboard Peter tested lately
[18:57:57] <JT-Shop> I think it is this ASUS E45M1-M PRO
[18:58:46] <Tom_itx> <pcw_home> ASUS E45M1-M PRO is my current favorite (no fan but runs circles around Atom MBs)
[18:59:02] <JT-Shop> you are the search guru Tom
[18:59:06] <JT-Shop> thanks
[18:59:48] <PCW> Yes ASUS E45M1-M PRO
[19:00:00] <Tom_itx> and confirmed :D
[19:00:06] <JT-Shop> thanks
[19:00:51] <PCW> needs C6 state and cool&quiet turned off in BIOS

[19:38:03] <tjtr33> will the 6I25 work in the PCIe slot of the E45M1-M PRO?
[19:38:35] <tjtr33> that vw sidecar could be very confusing seen from a rearview mirror
[19:47:10] <PCW> tjtr33 sure
[19:47:28] <tjtr33> thx
[20:00:06] <PCW> but a 5I25 is actually a little faster
[20:07:21] <tjtr33> PCW thank you, i havent read enough yet to see the differences,
[20:07:24] <tjtr33> the short description makes them seem almost identical despite the simpler bus i/f
[20:12:07] <PCW> 5I25 is PCI 6i25 is PCIE
[20:12:57] <PCW> but the 6I25 is really just a 5I25 hiding behind a PCIE/PCI bridge electrically
[20:13:42] <gmag> going to sleep. Good night and thanks again
[20:15:20] <tjtr33> yes, looks like a very useful product "These is a small speed advantage and some additional 6I25 features available if the card is runs as a native 6I25."
[20:16:33] <tjtr33> no matter till i buy one and use it. seems a good pair, that mobo, the 6i25 and having a free full pci slot left over
[20:45:49] <andypugh> Ah, I was just going to suggest to gmag that for 2 metres an hour an indivdual piston-press device would probably be fine.
[21:40:28] <sadara> Does anyone online atm know anything about servos?
[21:41:08] <sadara> or MESA products
[21:43:32] <tjb1> pcw_home or PCW
[21:43:44] <sadara> ?
[21:43:56] <tjb1> he works at mesa
[21:44:20] <tjb1> Saying his name pings him so he might respond if he is here
[21:45:15] <r00t4rd3d> just asking your question might get it answered also
[21:46:03] <r00t4rd3d> or pointed in the right direction
[21:46:11] <sadara> I have bought some servos, and I just wanted to make sure they are compatable with the mesa servo drive
[21:46:45] <sadara> datasheet for servo: http://www.electromate.com/db_support/downloads/APIBT171SERIES.pdf
[21:47:12] <r00t4rd3d> link to datasheet for the mesa drive?
[21:47:25] <sadara> and I was concidering the 8I20 servo drive: http://www.mesanet.com/nodatasheet.html
[21:47:40] <sadara> lol, try this instead: http://www.mesanet.com/pdf/motion/8i20man.pdf
[21:50:58] <sadara> all up :1x 7I49 resolver card, 1x 5I22 Anything IO, 1x 7I44 Eight Channel RS-422, 6x 8I20 2200W 3 Phase Amplifier
[21:53:23] <sadara> this is my first foray into servo territory
[23:19:03] <LeelooMinai> Any opinion of Chinese hobby CNCs like that: http://www.aliexpress.com/item/Free-shipping-110V-mini-desktop-cnc-engraving-machine-4-axis-cnc-3040Z-DQ-with-Ball-Screw/701792421.html?tracelog=back_to_detail_a
[23:19:29] <LeelooMinai> Are they, I don't know... at least reasonable for this price? :)
[23:28:26] <toner> ooh
[23:28:28] <toner> interesting
