[00:04:42] <theorb> theorb is now known as theorbtwo
[02:14:18] <cradek> home!!
[02:14:42] <Jymmm> cradek: You have Ruby Slippers????????????????????????????
[02:15:12] <Jymmm> cradek: Dude, You're not In Kansas anymore!
[02:15:31] <cradek> hahahahaha
[02:15:40] <Jymmm> btw Welcome Home!!!
[02:16:25] <cradek> thanks!
[02:16:33] <Jymmm> =)
[02:16:36] <cradek> now dinner!
[02:17:12] <Jymmm> bbq NY strip steak, baked potato, and corn with green beans
[02:35:44] <Jymmm> HOLY SHIT!! http://www.youtube.com/watch?v=oZZ84uJy48c
[05:41:37] <elmo40> you figure out the power, Jymmm?
[05:41:43] <elmo40> 220 split into 110
[06:33:23] <the_wench> asru: KimK said (sent via !later) There is one instance (already generated) of a cloud test in the example gcode files as tort.ngc . I can't find a copy of the generator itself right now.
[06:33:58] <asru> Much thanks. I'll take a look at it.
[06:36:37] <asru> can anyone comment on the TB6560 driver boards from China sold by, among others, Easysupply in Hong Kong?
[06:52:32] <KimK> Hi asru, I happened to be nearby. Sorry, can't help with the driver boards. What are you interested in finding out? On the tort.ngc, I went through it and added a scaling factor (just one) to all of the X,Y,Z and I,J,K values so we could enlarge the cloud to better fit the machine. You might choose to do the same. Unfortunately, I am separated from that file too.
[06:56:41] <asru> I found tort, and it is kind of neat as a test. I'll try it when I can run my machine without driving the downstairs neighbor nuts.
[06:57:22] <asru> As for the board, I am looking for an inexpensive setup for a university project I am supervising, and there are a couple of systems built around
[06:57:48] <asru> that board that are quite inexpensive. The problem is whether or not they'll work with EMC. It is claimed they work with Mach.
[07:09:34] <KimK> Parallel port connection?
[07:21:58] <elmo40> is it me or does Mach3 really miss steps? http://www.youtube.com/watch?v=HTlnAnPaQW8
[07:27:55] <asru> Kimk: Yes.
[07:42:32] <asru> One more shot before I sign off (it's late here in New York)--can anyone comment on driver boards built around the TB6560 chip?
[07:42:48] <asru> The claim is that they run with Mach3, but do they run with EMC?
[07:44:21] <elmo40> ok, this is just too cool. http://www.youtube.com/watch?v=iw0cKOEjnW8
[07:53:27] <KimK> asru: If they are parallel port connected, and they work with Mach3, I'm sure they would also work with EMC2.
[12:42:38] <X704> X704 is now known as WalterN
[14:28:19] <mhaberler_> mhaberler_ is now known as mhaberler
[14:46:09] <atmega> AMD Athoon 64 3000+ 2.0 GHz <-- OK for emc?
[14:46:24] <Jymmm> onboard video?
[14:47:10] <atmega> PCIe Video, VGA, DVI, and S-Video ports
[14:50:36] <atmega> my 8.4 emc box had onboard video, worked fine.
[14:51:46] <Jymmm> Then install 8.4
[14:52:05] <atmega> I did, but I'm ready to move on.
[14:52:18] <Jymmm> Well 8.4 != 10.x
[14:52:25] <atmega> mainly since the 10.04 upgrade completely hosed my 8.4 install
[14:52:48] <Jymmm> Never upgrade an OS, always install fresh.
[14:53:02] <Jymmm> hdd's are cheap.
[14:55:02] <atmega> should have, but I didn't. I think I'll blow $100 on a slightly faster box with non-integrated video.
[14:56:06] <atmega> heh... it even has 10.10 installed already. Are there emc packages for 10.10?
[15:00:27] <Jymmm> "it"?
[15:00:38] <atmega> the $100 box
[15:04:23] <SWPadnos> no
[15:07:55] <atmega> oh well, I'll just reinstall with the 10.04 livecd
[15:19:38] <skunkworks> 10.04 boots fast on the K&T. It is unreal. I think it boots as fast as the bios splash screen.
[15:35:22] <SWPadnos> skunkworks, see if you can get coreboot working, then the whole thing will be only a few seconds
[15:35:34] <SWPadnos> (this is left as an exercise for the reader)
[15:35:48] <skunkworks> heh
[16:13:09] <UncleG> SWPadnos can you point me to a solid mainboard for a mesa 5i20 servo system?
[16:19:37] <awallin> the Atom based itx boards seem to be quite good
[16:19:39] <mhaberler_> mhaberler_ is now known as mhaberler
[16:19:52] <awallin> if you don't need the pc for any number-crunching....
[16:27:06] <seb_kuzminsky> awallin: i agree
[16:27:27] <seb_kuzminsky> we used an intel d510mo motherboard on stuart stevenson's robot arm last weekend, it worked great
[16:27:50] <awallin> I tried compiling ocl on an Atom330 and it is _slow_ compared to both my laptop and my desktop...
[16:28:02] <seb_kuzminsky> i bet
[16:28:05] <SWPadnos> UncleG, I haven't done any testing of 10.04, but I can say that for 6.06, there's an expensive embedded system that works very well
[16:30:22] <Jymmm> 6.06?! Do you want today's lotto numbers too?
[16:30:23] <awallin> but those shiny new i7 systems don't seem to get any better real-time latencies than atom-boards...
[16:30:42] <elmo40> Jymmm: can ihave todays lotto numbers?
[16:31:01] <Jymmm> elmo40: you in the past?
[16:31:12] <SWPadnos> Jymmm, the system was designed/specced in 2007, and when there's a working design, you keep using it until you must change it
[16:31:22] <elmo40> SWPadnos: I like embedded systems... what make/model and where to purchase it?
[16:31:37] <elmo40> and what is 'expensive' ? $500?
[16:31:39] <SWPadnos> the one I used is the Acrosser AR-ES0892
[16:31:56] <SWPadnos> $800 with a core2 duo, 512M, and an 8G SSD
[16:32:00] <elmo40> core 2 duo :)
[16:32:12] <SWPadnos> yeah, T5600 - hard to find these days :)
[16:32:12] <elmo40> wow, $800.
[16:32:28] <SWPadnos> it would probably be less with more modern components, the CPU is $250 still
[16:32:29] <Jymmm> SWPadnos: Even if it's still working, there comes a time to just toss out tube equipment, mkay
[16:32:40] <SWPadnos> Jymmm, only if it stops working
[16:32:53] <Jymmm> SWPadnos: Nuh Uh
[16:32:58] <SWPadnos> the customer wanted identical systems
[16:33:19] <SWPadnos> trust me on this. you prove a design once, and then keep making it until you have to stop
[16:33:26] <elmo40> only if it is impeding your advancements.
[16:33:26] <Jymmm> SWPadnos: who cares wth the customer wanted, tell em what he needs
[16:33:46] <SWPadnos> Jymmm, I think I'll do it my way. that's why I'm still in business :)
[16:33:48] <elmo40> Jymmm: you must be american...
[16:34:09] <SWPadnos> elmo40, merkun, that is. I'm American :)
[16:34:40] <Jymmm> SWPadnos: That doens't make it right.
[16:34:53] <SWPadnos> in this case, I agree with the customer
[16:35:10] <archivist> long production of identical is good
[16:35:11] <SWPadnos> there is zero incentive to change something when the system works as designed
[16:35:25] <archivist> just works TM
[16:35:27] <Jymmm> For his needs, maybe. I'm not saying bleeding edge, but at least something within the last 3 years
[16:35:36] <SWPadnos> the only possible incentive might be cost, but in this case it's an $800 part in a million dollar machine
[16:36:05] <Jymmm> must be a very specific tasked machien
[16:36:09] <SWPadnos> and since I charge for my time, looking for a more modern replacement and then proving that it works as well as the old one would actually cost more
[16:36:11] <SWPadnos> it is
[16:36:35] <Jymmm> fair enough. but NO TUBES! (Unless RF)
[16:36:36] <SWPadnos> I'm talking about the embedded space, not general-purpose computing
[16:36:45] <SWPadnos> I think they don't use tubes, so it's OK
[16:37:08] <Jymmm> embedded, I guess I missed that.
[16:37:52] <Jymmm> SWPadnos: I hope at least you keep an eye out for replacement alternatives
[16:39:55] <SWPadnos> oh, I'm sure a more modern CPU and hard drive would be fine, but the kernel the system uses doesn't have SATA support, and they definitely want the same physical form factor, so it leads me to the same computer
[16:39:56] <UncleG> Thanks guys, when I get the servos tuned and finish some wiring I'll post pics and hardware.
[16:40:31] <SWPadnos> I could have put in a D510 or other Atom board and 10.04 (though I would have had to make changes to the software, since it uses a Mesa card and the firmware loading method has changed)
[16:40:53] <Jymmm> SWPadnos: What does the machien do (in a nustshell)?
[16:41:27] <UncleG> These air cyclinder works great, click, click, clack, click, click, I can't wait to see this machine move again..
[16:41:28] <SWPadnos> the PC and other stuff I did generates waveforms for a ~750KW power supply, which powers a specialized EDM machine
[16:42:20] <Jymmm> SWPadnos: Dude, you could have done that with a 555 or LC circuit
[16:42:41] <Jymmm> and pocket the rest =)
[16:43:47] <SWPadnos> yeah, but interfacing the 555 to the PLC would have been challenging :)
[16:43:53] <SWPadnos> (and I charge time and materials, dude)
[16:44:36] <Jymmm> SWPadnos: Let me see the contract! ;)
[16:44:49] <SWPadnos> I'd have to kill you first
[16:45:05] <Jymmm> Fine,
[16:49:29] <Jymmm> SWPadnos: http://animekmodels.com/Z_Scale_Billy.htm
[17:15:20] <Jymmm> If you were going to donate a CO2 Laser engraver to some non profit, who would have a NEED for such a thing?
[17:16:41] <seb_kuzminsky> Jymmm: the nonprofit hackspace i'm part of could use one!
[17:17:09] <Jymmm> seb_kuzminsky: where are yoou?
[17:17:42] <seb_kuzminsky> Boulder, Colorado
[17:17:51] <Jymmm> seb_kuzminsky: Are you 501c ?
[17:18:10] <seb_kuzminsky> the paperwork is still pending
[17:18:16] <Jymmm> ETA ?
[17:18:53] <Jymmm> seb_kuzminsky: website?
[17:18:57] <seb_kuzminsky> i'm not really sure, a paperwork guy is handling it. I think the preliminary papers are ready already, so we should be up and running
[17:19:13] <seb_kuzminsky> SolidStateDepot.com, but i just noticed it's down atm :-(
[17:19:53] <Jymmm> seb_kuzminsky: Well, if you can get it up and willing to pay shipping or pickup in SD, you *might* be able to get one.
[17:20:39] <seb_kuzminsky> what state is it in?
[17:20:44] <Jymmm> SD
[17:20:47] <seb_kuzminsky> i mean, how close to running is it?
[17:21:05] <Jymmm> It's running, just on Win98 with the included computer
[17:21:35] <Jymmm> and coreldraw 10 (current is 15)
[17:21:46] <seb_kuzminsky> wowsers
[17:21:59] <seb_kuzminsky> got any pics? how much does it weigh?
[17:22:08] <Jymmm> nfc
[17:22:25] <Jymmm> few hundred pounds I'd suspect
[17:22:36] <Jymmm> say 300
[17:22:41] <Jymmm> give or take
[17:22:45] <seb_kuzminsky> pretty little
[17:22:57] <seb_kuzminsky> might even fit in my gutless 1/2-ton truck
[17:23:16] <Jymmm> Oh it should, but get your website up so I can give them the link
[17:23:29] <seb_kuzminsky> i'm very interested - would be a fun retrofit project
[17:23:56] <Jymmm> seb_kuzminsky: and verify the 501c status
[17:25:35] <seb_kuzminsky> i just pinged our webmaster
[17:25:49] <Jymmm> seb_kuzminsky: Would you be willing to goto SD ?
[17:27:08] <atmega> aren't SD and CO practically the same place
[17:27:18] <SWPadnos> on one edge, maybe
[17:28:23] <seb_kuzminsky> yeah we share a border
[17:33:58] <seb_kuzminsky> oh wait, Co doesnt border SD
[17:34:06] <seb_kuzminsky> Nebraska is in the way
[17:34:21] <Jymmm> Well?
[17:34:57] <seb_kuzminsky> still might be doable, it'll depend on the machine, i'll talk to the guy and find out more
[17:35:57] <Jymmm> k
[17:40:20] <cradek> good morning!
[17:40:42] <Jymmm> Mornin Dorthy
[17:40:57] <seb_kuzminsky> hi cradek :-)
[17:41:48] <cradek> what a nice 14 hours of sleep that was (good grief)
[17:41:58] <SWPadnos> heh
[17:42:00] <seb_kuzminsky> are you back home and all rested?
[17:42:07] <SWPadnos> I wish I could sleep past 7:30 or so
[17:42:18] <Jymmm> cradek: "There's no place like home. There's no place like home."
[17:43:14] <skunkworks> cradek: welcome home!
[17:43:33] <Jymmm> If cradek is Dorthy, does that make Stuart "the Wizard"?
[17:44:07] <cradek> thanks :-)
[17:45:15] <Jymmm> SWPadnos: You would be one of the flying monkeys! Mister I have more frequent flyer miles than most pilots do!
[17:45:27] <SWPadnos> heh
[17:46:08] <SWPadnos> (I'm still under 1/2 million miles though)
[17:47:41] <Jymmm> Well, you can still get a round trip ticket the The Moon - it's only 238,857 miles one-way.
[17:47:56] <SWPadnos> yes, almost exactly 1/2 my miles
[17:48:05] <cradek> seb_kuzminsky: it would be terrible if you had to visit on your way to pick that up.
[17:49:42] <seb_kuzminsky> cradek: good idea! that would not suck :-)
[17:49:57] <SWPadnos> heh
[17:50:16] <SWPadnos> (or on the way back even, so cradek can take a look at it :) )
[17:50:25] <seb_kuzminsky> heh
[17:50:46] <SWPadnos> ack! even my laptop stinks
[17:50:48] <seb_kuzminsky> every time i hang out with cradek, i end up cutting about a zillion zip ties :-)
[17:50:59] <Jymmm> SWPadnos:
[17:51:07] <Jymmm> SWPadnos: Um....
[17:51:07] <seb_kuzminsky> Jymm's a man of few words
[17:51:20] <Jymmm> SWPadnos: Do I EVEN have to say it?
[17:51:31] <Jymmm> * Jymmm waits for it....
[17:51:32] <SWPadnos> Jymmm, there is at least one chain smoker at MPM, it's not my flatulence this time
[17:51:49] <SWPadnos> err. s/this time//
[17:51:51] <SWPadnos> :)
[17:52:21] <Jymmm> SWPadnos: See there ya go... you made me say it... CRAPTOP!!! lol
[17:52:32] <SWPadnos> smoketop this time
[17:52:38] <Jymmm> haha
[17:53:04] <Jymmm> SWPadnos: denatured alcohol
[17:53:20] <Jymmm> all batteries removed of course
[17:53:29] <Jymmm> includng cmos
[17:54:57] <SWPadnos> I wonder if that's possible on this laptop
[17:55:26] <Jymmm> I just assumed that since you replaced the LCD on it, that you knew where the cmos battery was and how to remove it.
[18:23:31] <IchGuckLive> hi all is there a progamm that recalculates an inch programm to a metric?
[18:24:16] <SWPLinux> no, but you could add G20 at the top
[18:26:21] <IchGuckLive> if the control does use the G20 G21 but otherwise i got to phyteon it myself
[18:26:34] <cradek> seb_kuzminsky: I cut the first zillion - I saved you some work this time
[18:27:31] <SWPLinux> IchGuckLive: yes. theoretically, you can scale any XYXUVW value to (value * 25.4)
[18:27:37] <cradek> seb_kuzminsky: I wish you could have seen that run. you did the hard work. after you left, I hooked up about six wires and cut six others, and it ran
[18:27:59] <SWPLinux> and that would do it (leave ABC, S, and anything else alone, of course)
[18:28:12] <cradek> IchGuckLive: then your arcs will all be broken of course, and your feed rates will be amazingly slow
[18:29:06] <IchGuckLive> the circelse will fail i guess
[18:29:49] <SWPLinux> oh right. F and IJK also need to be scaled (probably)
[18:29:51] <cradek> whether it's hard depends on what's in the gcode
[18:29:53] <seb_kuzminsky> cradek: i wish i could have seen it too!
[18:30:01] <seb_kuzminsky> the videos were cool
[18:30:19] <cradek> thought that might help :-)
[18:30:23] <SWPadnos> Jymmm, different laptop - I brought the small one with me
[18:30:31] <SWPadnos> (and the battery isn't near the LCD in that one either :) )
[18:30:39] <seb_kuzminsky> but again it was you who did the hard parts - figuring out what wires are supposed to go where - i'm just the screwdriver monkey :-)
[18:30:48] <IchGuckLive> ok we will sea what the costemer whants to do i send im a return massege he shoudt use G20 at the start of a inch programm on a Metric mashine
[18:31:06] <Jymmm> SWPadnos: oh
[18:31:24] <SWPadnos> IchGuckLive, I hope it's a very old control if it doesn't have G20/G21
[18:31:28] <cradek> most controls really can read either
[18:31:48] <cradek> my 1974 lathe had a toggle switch to tell it whether the paper tape was written in inch or mm
[18:31:59] <IchGuckLive> By#
[18:32:11] <SWPLinux> see you
[18:32:14] <SWPLinux> :)
[18:32:28] <SWPLinux> wow. what a lag
[18:32:34] <IchGuckLive> O.O
[18:32:57] <SWPLinux> I have two machines here, and when I type on one, it takes a second or more to appear on the other
[18:33:11] <skunkworks> The k&t didn't have metric. You bought the mahcine with a different control.
[18:33:25] <IchGuckLive> the recomendation came from a programmer of a HAAS Europ Depo so i dont now if he nows his own controls
[18:34:03] <IchGuckLive> maybe they are testing me
[18:37:01] <Jymmm> alex_joni: When you built your webradio, dod you specifically program the controls for it's targeted usage, or somewhat generically for use with the encoder?
[18:37:08] <Jymmm> s/dod/did/
[18:48:11] <Xavier_H> Hi all
[18:48:36] <Xavier_H> I would get hostmost2 source from git
[18:48:50] <Xavier_H> but I encountered some problems
[18:49:14] <Xavier_H> To get the initial sources
[18:49:56] <Xavier_H> I type : "git clone git://git.linuxcnc.org/git/hostmost2-firmware.git hm2-dev"
[18:50:24] <Xavier_H> And git respond : "Initialized empty Git repository in /home/xavier/Bureau/hm2-dev/.git/
[18:50:26] <Xavier_H> fatal: The remote end hung up unexpectedly"
[18:51:16] <Xavier_H> My hostmost2-firmare address seem to be good...
[18:51:26] <Xavier_H> someone has en idea?
[18:52:42] <Xavier_H> I can't believe that nobody use linuxcnc git here! ;-)
[18:52:44] <SadMan> it's hostmot
[18:52:46] <SadMan> not hostmost
[18:53:08] <Xavier_H> Arg!!!! Damn me!
[18:53:36] <Xavier_H> THANK YOU, I read and reread at least 10 times the address!
[18:53:42] <SadMan> np ;-)
[18:54:15] <Xavier_H> ok now I can start the work
[18:54:20] <Xavier_H> thank you again!
[18:55:06] <psha> KimK: ping
[18:55:33] <Xavier_H> psha : pong (ok I'm leaving ;-) )
[18:57:56] <KimK> psha: Hi! What news?
[18:58:01] <psha> yes, circles working
[18:58:33] <KimK> psha: Excellent! Screenshots?
[18:59:48] <psha> not yet :) but it's like crosshair
[18:59:56] <psha> only circle :)
[19:00:01] <psha> adjustable via hscale
[19:04:14] <jepler> by the way, this weekend I helped someone with xilinx ise webpack 12 build a hostmot2 firmware. It was necessary to remove the "-r" argument to the call to map in build.py
[19:04:14] <KimK> psha: Great, I'll look forward to seeing it. (And maybe using it someday?) I need to Google a list of video-input cards and cameras that are Linux-friendly. Video4Linux, was it? Or maybe Vid4Lin? Something like that.
[19:04:47] <jepler> "-r" was added to make some "extra full" 5i20 designs fit, so you may or have to remove those from firmwares.txt when you encounter them
[19:04:58] <jepler> KimK: always glad to have more developers
[19:05:05] <jepler> bbl, (late) lunchtime here
[19:05:17] <psha> KimK: something like nearly any webcam :)
[19:05:38] <KimK> jepler: Too bad I wasn't there too. I downloaded Xilinx, what 12.2 was it? And I'd like to install it and learn how to use it for the basic bitfile stuff, anyway.
[19:06:36] <psha> KimK: andy sent link yesterday http://cgi.ebay.co.uk/5-0-M-HD-USB-Mini-Webcam-Video-Camera-PC-Mac-Linux-/170536942784?pt=UK_Computing_ComputerComponents_Webcams&hash=item27b4cb3cc0#ht_5050wt_907
[19:06:47] <psha> KimK: seems to be easy mountable
[19:09:13] <KimK> psha: What video card are you using? And have you found a camera that is pretty good as far as macro(?) or "microscope"(?) or close-focus(?) abilities?
[19:09:36] <psha> i'll take a look onto usb microscopes in a week or two
[19:09:59] <psha> but problem with them is that they are not as popular as regular webcams
[19:10:07] <KimK> What width or field-of-view are you getting with what you're using?
[19:10:26] <KimK> I want it to be close, but not too close, lol
[19:10:52] <KimK> I want it to be "just right" haha
[19:11:25] <psha> i think i'll take a look on something like http://www.amazon.com/Dino-Lite-AM2011-Handheld-Digital-Microscope/dp/B003Q9OVFW
[19:12:00] <psha> but that camera may be unsupported
[19:13:29] <psha> good sign is that it's Mac OS compatible
[19:17:22] <psha> KimK: but if you don't need high magnification something like ordinar webcam will work nice :)
[19:47:25] <Xavier_H> Re, I am looking on Hostmot2 firmware sources but I don't know how to begin with them. "hostmot2_import.tcl" does'nt produce projet in ISE.
[19:48:57] <Xavier_H> Someone can tell me what is the most important files (top, configuration scripts,...)?
[19:49:21] <grommit> psha: images at http://bgp.nu/~tom/pub/tabs-nocntl.png and http://bgp.nu/~tom/pub/tabs-cntl.png
[19:51:51] <Xavier_H> My project is to implement a "PA035C" absolute encoder module (sanyo denki servo)
[19:52:06] <Xavier_H> in the hostmost firmware
[19:53:11] <Xavier_H> I have all the protocol documentation needed
[19:54:22] <grommit> This one would be nice for those times you have the camera in your spindle and turn it on by accident :-)http://www.thinkgeek.com/interests/dads/c6d1/
[19:54:36] <Xavier_H> nobody can help me to explain me (shortly) the source organisation?
[19:55:45] <Xavier_H> I have no problem using ISE nor understand VHDL
[19:57:13] <SWPadnos> Xavier_H, there is a resolver module in the hostmot2 firmware, but it needs driver support
[19:57:49] <Xavier_H> absolute resolver?
[19:58:15] <SWPadnos> there are build scripts for the Mesa firmware, I don't know the exact names of the files, but there is basically a top module that instantiates the sub-modules, as well as defining a pinout
[19:58:17] <Xavier_H> compatible with sanyo denki absolute "PA035C" encoder?
[19:58:22] <SWPadnos> oh, no, I don't think it's absolute
[19:58:58] <Xavier_H> I found the incremental resolver
[19:59:04] <SWPadnos> I believe Mesa has an absolute encoder module, but I don't know about resolvers (I know resolvers are absolute within an electrical cycle, I'm not sure if there's support for a "turns counter")
[20:00:07] <Xavier_H> Ok I will look at that
[20:00:53] <Xavier_H> I found the script to make all the firmware, this is explain in README file I think
[20:01:19] <Xavier_H> but what is the top vhdl file?
[20:01:46] <SWPadnos> I don't know if there is a standard absolute encoder module for hostmot2, I just remember PCW talking about absolute encoders for some project he was working on
[20:02:12] <SWPadnos> there is a file which is a list of top files to generate images from
[20:02:25] <SWPadnos> s/image/bitfile/
[20:09:35] <psha> grommit: thanks
[20:10:03] <psha> grommit: controls are HUGE :)
[20:10:31] <psha> may be it's better to move extra tabs to separate window (like color picking window for colors)?
[20:13:22] <Xavier_H> where is the "settings.sh" script?
[20:13:44] <SWPadnos> no idea :)
[20:14:03] <SWPadnos> that may be from the Xilins tools actually
[20:14:22] <SWPadnos> you have to run that to set up Xilinx paths and environment variables (imaybe)
[20:14:45] <Xavier_H> ok thank you
[20:15:09] <Xavier_H> I will search them in my ISE tree
[20:15:24] <SWPadnos> that was a wild guess actually, I don't know for sure
[20:16:02] <Xavier_H> I have 10.1 version of ISE (linux)
[20:16:32] <SWPadnos> ok. 9.2i works, and some version of 12 also works, so you may be lucky and have 10 work as well
[20:17:32] <Xavier_H> ok my version is quite old... The last time I use it was for the armadeus projet years ago
[20:17:44] <SWPadnos> don't throw it away, try it first :)
[20:18:18] <Xavier_H> no "settings.sh" in my ISE tree...
[20:19:40] <SWPadnos> ok, looking at the README, that is definitely "whatever it is you're supposed to run to set up the Xilinx build environment"
[20:20:07] <SWPadnos> it was called settings.sh in 9.2i, I don't know what it's called in 10 (maybe Xilinx.sh or something like that)
[20:20:24] <SWPadnos> find ~ -iname "xilinx*.sh"
[20:20:31] <SWPadnos> might gove you a long list of files :)
[20:20:33] <SWPadnos> give
[20:21:58] <Xavier_H> My english is quite bad and I am not sure to understand you
[20:22:15] <Xavier_H> I have already ISE installed on the computer
[20:22:34] <SWPadnos> ok
[20:22:36] <Xavier_H> I used it some years ago
[20:22:51] <SWPadnos> IS has a script that you run to set up environment variables and paths
[20:23:17] <SWPadnos> you would run this before starting the development environment, to set up tool paths
[20:23:24] <SWPadnos> (xilinx tools, that is)
[20:24:10] <psha> grommit: i've replaced image on wiki
[20:27:29] <Xavier_H> I am sorry but I don't understand what are you meaning by set development environment variables, which one? Xilinx path one or hostmot_firmawe particular one?
[20:28:44] <Xavier_H> ok I found settings32.sh
[20:29:50] <SWPadnos> it should be in your ~/Xilinx directory
[20:29:56] <SWPadnos> Xilinx(whatever version it is)
[20:30:03] <Xavier_H> ISE directory
[20:30:11] <Xavier_H> for me
[20:30:36] <Xavier_H> Xilinx/ISE/settings32.sh
[20:31:16] <SWPadnos> ok
[20:31:27] <Xavier_H> I will try to continue building the source
[20:31:47] <Xavier_H> I don't distirb you anymore (until the next time)
[20:31:56] <SWPadnos> ok. good luck with it
[20:32:00] <Xavier_H> *I won't
[20:32:39] <Xavier_H> Thank you I neek to study them
[20:32:51] <Xavier_H> Thank you again for the halp
[20:32:54] <Xavier_H> help
[20:33:03] <SWPadnos> you're welcome
[20:51:07] <PCW> HostMot2 should build with 9.x, 10.x,11.x and 12.x
[20:51:09] <PCW> (12.X is buggy however, necessary for Spartan6 but needs help
[20:51:10] <PCW> to compile spartan6 stuff correctly (retain hierarchy))
[20:52:05] <PCW> They also managed to break the rectangular selection copy& paste in the 12.X editor
[21:43:35] <KimK> PCW: Hi, Peter. I thought I had already downloaded Xilinx 12.2 or 12.3, but apparently not on any of the drives I have with me. Would you recommend that I download and install 12.3, or try to find some earlier version? And if so, which one? Thanks.
[21:44:28] <KimK> PCW: And how are things coming along on your resolver/servo card (was it the 7i49)?
[21:46:52] <PCW> 12.3 should be fine (only trouble I had was with Spartan6 and the editor (in 12.1))
[21:46:53] <PCW> production 7I49 cards are being built now
[21:55:55] <KimK> OK, thanks, I'll go get the 12.3. And let me know if I can help (along with advice from Seb) with your 7i49 driver.
[21:57:27] <PCW> I think theres a proto 7I49 I can send you is you want to try it plus theres a bit of a manual now
[21:57:37] <PCW> (if you want)
[22:47:30] <KimK> PCW: Sorry, I was on the other PC. Sure, I presume the prototype matches the final configuration, even if it has kludges, etc.? How long until you have production versions? (I hate to take your only one.)
[22:48:29] <andypugh> Simalar query re 7i64 :-)
[22:49:01] <KimK> Oooh, what's the 7i64?
[22:49:37] <andypugh> 12 in 12 out 24V 2.5A IO card
[22:50:07] <andypugh> Sorry, 48V
[22:50:16] <andypugh> And 24 in / 24 out
[22:52:01] <KimK> Ah, multiple improvements compared to the 7i37? Excellent. Does it multiplex in some way so as to still use only one cable/port?
[22:52:20] <andypugh> I am amused by the idea of the maximal-config, which is 4 x 8 of them, for 1536 IO pins
[22:53:18] <andypugh> It uses serial comms
[22:54:09] <andypugh> Same as the 8i20, which is why I am asking as there are dangling hooks in the 8i20 driver code for it.
[22:54:44] <KimK> Well, 1536 is not unreasonable compared to maximal-config of "middling" PLCs, but yes, that is still a lot of I/O. Serial, interesting, what's the max delay?
[22:55:47] <KimK> * KimK would be more worried about CL with that much I/O
[23:04:29] <andypugh> Good question on max delay. I was planning to update in the servo thread. I wonder if it should be in the base thread?
[23:04:58] <andypugh> Ah, no, wait. Hostmot2 only works in the servo thread. Ignore that.
[23:05:10] <andypugh> So max delay is 1mS
[23:05:24] <andypugh> (Or whatever servo thread period you run)
[23:43:03] <KimK> OK, 1ms. You know, there's a note somewhere in CL saying that it only updates at 1ms *even if it is put in a faster thread*. I wonder what's up with that? It usually varies around 100-300us (per ladder viewer) when I get it loaded up to "typical" size.
[23:44:00] <KimK> So you probably wouldn't gain a lot by a faster thread anyway, but it's still curious that it has some built-in limit.
[23:46:16] <KimK> Dinner, back in a bit
[23:51:15] <JT-Hardinge> I'm thinking I should be able to calculate surface finish with feed per tooth and insert radius???
[23:53:55] <andypugh> Yes
[23:54:35] <andypugh> Though it assumes that the training edge is not tangent to the surface
[23:56:40] <andypugh> http://www.1728.com/circpart.htm AB is feed, surface roughness is DE
[23:57:09] <JT-Hardinge> say I'm facing off a 50mm wide stock with a 75mm diameter face mill then the center has the smoothest part and the edges have more ripple?
[23:57:49] <andypugh> Other way round, I think
[23:58:19] <andypugh> Consider a 75mm part.
[23:58:26] <JT-Hardinge> ok
[23:58:41] <andypugh> Though it is late here
[23:58:46] <JT-Hardinge> very
[23:58:56] <JT-Hardinge> midnight I suppose
[23:59:05] <andypugh> Just about
[23:59:18] <JT-Hardinge> ok the edges have the smallest scallop
[23:59:27] <JT-Hardinge> and the center has the most
[23:59:42] <andypugh> That's how my visualisation comes out
