[00:05:54] <zee-Lathe> help!
[00:24:48] <zee-Lathe> nm
[00:24:55] <zee-Lathe> finally got this encoder responding
[00:41:08] <zeeshan> http://linuxcnc.org/docs/html/examples/spindle.html
[00:41:18] <zeeshan> the code for spindle syncronized motion is wrong
[00:41:22] <zeeshan> well its not wrong
[00:41:24] <zeeshan> it has a typo
[00:41:34] <zeeshan> loadrt encoder num_chan=1 should be loadrt encoder num_chan=4
[00:41:53] <zeeshan> cause setp encoder.3.position-scale etc should be 0 not 3 if its going to be 1
[02:01:22] <Deejay> moin
[04:48:24] <miss0r> right next to me is now standing a mint condition Roland CAMM-3 PNC-3100 mill yay ! got it for only ~1000USD
[04:56:04] <archivist> another happy bunny, tell us when you have it under linuxcnc :)
[04:56:45] <miss0r> From what I hear, that is going to be a challange, but I am hard at work already
[04:58:02] <miss0r> Time to go offline and do some serious work. cya
[05:40:37] * SpeedEvil wonders if that's '~1000' or '1300'.
[05:43:12] <jthornton> morning
[05:47:43] <SpeedEvil> Mnorngin
[10:29:09] <zeeshan> helllooo
[10:48:56] <miss0r> I am looking for someone with experience setting up a roland camm-3 mill. I have hit a dead end, everything is connected, the drivers installed & the software downloaded & installed. I have no idea where to go from here(I have some experience milling) I have no idea if the computer is even 'talking' to the mill. So can anyone please help me? (I have spend roughly 8 hours searching the web
[10:48:56] <miss0r> without any luck)
[11:01:04] <jdh> it uses LinuxCNC?
[11:02:24] <miss0r> jdh, right now I was hoping to get it running with its generic software, to see if it is even working properly. Then I will convert it to linuxCNC. I know it is a scretch asking in here for non linuxCNC software, but I have no idea where else to go- theres close to nothing available online
[11:03:50] <cradek> it's possible someone here can help, but you will have to give A LOT more information about what you have.
[11:04:24] <cradek> if nothing else, I suggest taking a bunch of photos and writing down everything you know, and making that all available online
[11:04:41] <cradek> ... if you don't know where to start
[11:04:59] <cradek> but if you do know where to start, maybe you have some more specific questions?
[11:05:25] <cradek> but of course it's true the software we (collectively) know the most about is linuxcnc
[11:05:40] <cradek> a lot of us do know a lot about the hardware you find in machine tools
[11:05:49] <miss0r> well. For a start I would just like to know how to determin if the computer has connection to the mill controller. I guess that is where I want to start
[11:06:07] <zeeshan> is it a parallel port
[11:06:15] <miss0r> yes
[11:06:31] <zeeshan> if you had linuxcnc
[11:06:41] <zeeshan> you could just energize each pin and measure the pin on the other side with a volt meter
[11:06:46] <cradek> describe what you have and what you know about it
[11:06:47] <zeeshan> you'd see it either go to 3.3 v or 5V
[11:08:38] <miss0r> +cradek: I have a Roland DG CAMM-3 PNC-3100 mill. I have it hooked up with the controller and the key panel. I have the controller connected to the PC with a parallel cable. On the computer I have installed the corresponding driver and Modela Player. I can move the machine with the key panel and do all it can do from there. But I have no tools and/or means of telling if the computer even
[11:08:38] <miss0r> knows how to talk to the mill.
[11:12:03] <jdh> https://groups.yahoo.com/neo/groups/CAMM-3/
[11:12:05] <jdh> tried there?
[11:12:47] <miss0r> jdh: I have. I am hoping someone will answer in time. I wrote in there 4 hours ago
[11:13:11] <Connor> I would check cnczone.com too
[12:13:39] <IchGuckLive> hi all B)
[12:14:52] <IchGuckLive> miss0r: still online on pnc-3100
[12:14:57] <tjtr33> miss0r, google modela and searc youtube for tutorials. lotsa hits. from what i see you need to get a model first, so get something very simple. not interactive, not informative, no scrolling lines of code seen! tool path simulation yes. pretty blind load & go.
[12:15:48] <tjtr33> the software controls many roland mini mills
[12:16:09] <IchGuckLive> its on the maufacturing date 2009 <>
[12:16:18] <kfoltman> hi IchGuckLive
[12:16:24] <IchGuckLive> they changed the communication
[12:16:28] <kfoltman> IchGuckLive: ib/e is on the way from Germany :)
[12:16:58] <IchGuckLive> its available in Dublin 2
[12:17:34] <kfoltman> ????????
[12:17:51] <IchGuckLive> you are in irelend
[12:17:54] <kfoltman> yes
[12:18:14] <kfoltman> I ordered some step clamps and end mills too, not just the proxxon :)
[12:18:17] <IchGuckLive> McQuillan tools got all proxxon items
[12:18:48] <kfoltman> but possibly at rip-off prices
[12:19:13] <kfoltman> but, good to know if I need something quick
[12:19:21] <IchGuckLive> dident bought anything there but Proxxon prices are fixed all over the world
[12:19:47] <IchGuckLive> as fixed as Mcdonalds +- some amont
[12:20:19] <kfoltman> I've tried some local online shops first, but they wanted about 100+vat for the ib/e
[12:20:47] <kfoltman> sorotec sells the newer model (ibs/e) for 79+shipping, which comes slightly below 100
[12:21:10] <IchGuckLive> up to you
[12:21:40] <kfoltman> I'm buying things from mcquillian tools from time to time though (the store in city centre, dublin 1, anyway)
[12:22:12] <IchGuckLive> oh i dont know witch there are more then 4 arpound dublin
[12:22:32] <IchGuckLive> maybe its a spechal plumbing as there is also a gardener store
[12:22:35] <kfoltman> I've only found one, and that's purely by accident :)
[12:24:13] <kfoltman> http://www.mcquillantools.ie/store-locator one in Dublin 1, one in Blanchardstown, one in Cork
[12:24:57] <IchGuckLive> you are local im only google
[12:25:12] <tjtr33> miss0r, did you read the manual? http://www.manualslib.com/download/604438/Roland-Pnc-3100.html
[12:25:13] <tjtr33> miss0r looks like spooled serial cnc appliance, not at all like linuxcnc ( or most cncs ) built for artists not machinists
[12:25:27] <kfoltman> IchGuckLive: anyway, just telling you what I've found :)
[12:25:36] <IchGuckLive> tjtr33: do you think he is still around
[12:26:12] <kfoltman> IchGuckLive: I'm waiting for the 20mm clamp (from France) and some belts/pulleys/bearings (from China) so I'm not in a hurry :)
[12:26:19] <miss0r> I've read all the manuals. The one thing I did not do was hit print. It seems to be working properly, thanks people
[12:26:26] * kfoltman is an ebay junkie
[12:26:37] <KimK_w> miss0r: Don't forget that LinuxCNC is downloadable as a run-live CD, you could try it on-the-fly without giving up your current installation (if you can boot from CD). See http://linuxcnc.org/index.php/english/download . You could also install as dual or multi boot, if that helps.
[12:27:13] <IchGuckLive> miss0r: you are the mam of the day
[12:27:21] <miss0r> right.... :)
[12:27:25] <IchGuckLive> man ;-)
[12:27:33] <tjtr33> IchGuckLive, listed & mis<tab> completes, so he didnt log off od away
[12:27:59] <IchGuckLive> O.o
[12:28:09] <tjtr33> haha start damnit! {Louder if if it doesnt work!}
[12:28:14] <kfoltman> BTW, I have a beaglebone that I might use for LinuxCNC (to replace grbl that I'm currently using), any idiot-friendly solutions out there?
[12:28:56] <IchGuckLive> did you look in the wii
[12:29:01] <IchGuckLive> wiki
[12:29:05] <tjtr33> miss0r, KimK it uses a proprietary ascii command set, not even hpgl some kinds RolandGL
[12:29:16] <kfoltman> IchGuckLive: not yet, I'll look if it's there :)
[12:30:12] <tjtr33> miss0r, you cant control the motors or spindle thru the cable, you _ask_ for it using a language
[12:30:14] <miss0r> tjtr33, so LinuxCNC is out?
[12:30:19] <miss0r> indeed
[12:30:40] <miss0r> In other words: I would have to remake the electroncis inorder for it to be able to run with LinuxCNC
[12:31:11] <tjtr33> no, you can go around the old control, you have to dig inside and see where you can get to the real parts, past their 'brainz'
[12:31:42] <tjtr33> more surgery and adding parts than re-inventing/engineering
[12:32:06] <IchGuckLive> its marked at the Hstages
[12:32:14] <IchGuckLive> XYZ
[12:32:34] <IchGuckLive> the spindle is a 6bit order i wrote a comp for it
[12:33:35] <tjtr33> IchGuckLive, mark those with 'miss0r' if they have to do with his Roland project. i cant tell where you're aiming ;)
[12:33:58] <IchGuckLive> ok
[12:34:30] <tjtr33> IchGuckLive, where did you find the hbridge connections?
[12:35:51] <IchGuckLive> in the V2.x version add pnc3100 its around the on of button corner marked on mashine base
[12:36:16] <IchGuckLive> if it is a modified v1.1x from 3000
[12:36:42] <IchGuckLive> its on buotton of the top plate
[13:08:52] <lair82_> Hello pcw_home
[13:09:25] <CaptHindsight> pcw_home: what are you calling the HM2 UDP ethernet again?
[13:09:58] <pcw_home> Hi
[13:10:00] <pcw_home> CaptHindsight: do you think that AMD MB/CPU is a good risk (less than say 50 usec jitter)
[13:10:12] <CaptHindsight> hm2_ether
[13:10:50] <CaptHindsight> pcw_home: the e350m1 are ~10uS with 3.4.55 RTAI
[13:11:00] <CaptHindsight> lower with a tweaked kernel
[13:11:01] <pcw_home> yeah the driver is hm2_ether (to match hm2_pci and eventually hm2_EPP and hm2_spi)
[13:11:07] <lair82_> Is that correct in saying that if I am out of CPU, I need a faster cpu??
[13:11:22] <CaptHindsight> great, trying to burn my skull flash with that term
[13:11:23] <pcw_home> i suspect the AMD will just work (with som BIOS twaeks)
[13:11:56] <pcw_home> but I have no direct experience
[13:12:06] <CaptHindsight> http://www.amazon.com/ASRock-E350M1-Dual-Core-Mini-ITX-Motherboard/dp/B004KABOZG but now $88 on Amamzon, newegg might be permanently out
[13:13:10] <pcw_home> lair82_ Yes faster CPU (using the bigger hammer theory anyway)
[13:14:12] <lair82_> We pretty much go by the old saying " Go big or Go Home " anyway, so I guess it fits
[13:14:28] <lair82_> I can try machinekit on the J1800/J1900 if there are doubts
[13:15:03] <lair82_> I guess it would be the J1900 for the PCI slot
[13:15:46] <pcw_home> Machine kit/Xenomai ought to work on the J1800/J1900s but I have no experience with it
[13:15:59] <lair82_> Or this one maybe? http://www.gigabyte.us/products/product-page.aspx?pid=4895#ov
[13:16:36] <pcw_home> Yes or the Asus equivalent : j1800i-a
[13:20:07] <CaptHindsight> lair82_: I can try your program on an E350m1 but i only have PCIe 6i25's for it
[13:20:22] <lair82_> Not holding anybody responsible, but which one would be a better bet
[13:20:56] <pcw_home> e 350 is out since it has to PCI slot as is no faster than what you have
[13:21:06] <CaptHindsight> lair82_: is this for one machine? are fans an issue? just need PCI?
[13:21:07] <pcw_home> has no PCI slot
[13:21:17] <lair82_> We are willing to buys some boards and give it a whirl, just looking for a little direction
[13:21:23] <CaptHindsight> yeah ,nevermind
[13:21:37] <CaptHindsight> I have tons of boards here
[13:21:51] <lair82_> I have three turning centers, all having the same issues. I
[13:24:56] <pcw_home> The J1800/I1900 boards are very nice in that they are fanless and fast but will probably need xenomai or preemt-rt + machinekit currently
[13:24:58] <pcw_home> because if the lack of graphics support (or live with slow graphics and 2.6 RTAI hernsl)
[13:25:13] <pcw_home> kernel
[13:28:49] <lair82_> not sure if I missed anything, my pc froze, last I said was fans arent an issue
[13:29:33] <CaptHindsight> http://www.gigabyte.com/products/product-page.aspx?pid=4343#sp is what we have been using for more complex machines
[13:29:37] <CaptHindsight> works with new kernels and has accel graphics
[13:29:58] <CaptHindsight> you didn't miss anything :)
[13:31:17] <pcw_home> for the minimum amount of changes its probably better to just use a faster standard MB
[13:31:19] <pcw_home> so if those have decent latency (less tha 50K) those are probably a good choice
[13:31:33] <CaptHindsight> https://www.asus.com/Motherboards/F2A85V_PRO/ is what memleak uses for all the initial RTAI development
[13:31:57] <CaptHindsight> all AMD in the past 5+ years are 10Us or less
[13:32:21] <CaptHindsight> I can't recall one higher even going back 10 years
[13:32:44] <pcw_home> OK so
[13:32:46] <pcw_home> http://www.newegg.com/Product/Product.aspx?Item=N82E16813157465
[13:32:47] <pcw_home> is probaby a good bet
[13:34:28] <CaptHindsight> + FM2 APU ~$50
[13:35:38] <CaptHindsight> coreboot supports most Trinity APU's
[13:36:04] <lair82_> http://www.newegg.com/Product/Product.aspx?Item=N82E16819113343
[13:36:16] <pcw_home> any of those will be at least twice as fast as the Atom
[13:36:20] <lair82_> Look like a winner?
[13:36:42] <CaptHindsight> http://www.newegg.com/Product/Product.aspx?Item=N82E16819113330 if you want coreboot
[13:36:42] <lair82_> I have a bunch of memory for that board anyway
[13:36:57] <pcw_home> I would say its a good bet
[13:37:22] <pcw_home> you may be able to just move your hard drive
[13:39:27] <lair82_> Not to sound like I don't know what I'm doing but what is Coreboot?
[13:40:53] <CaptHindsight> lair82_: open source firmware to replace BIOS/EFI, gets you 2 second boots from power-on to login
[13:42:48] <lair82_sim> My pc tied up again, move to my lncnc sim machine.
[13:44:45] <lair82_sim> pcw_home which processor did you mean by a good bet, and what did coreboot mean
[13:46:14] <CaptHindsight> lair82_sim: coreboot is an open source firmware to replace BIOS/EFI, gets you 2 second boots from power-on to login
[13:46:42] <lair82_sim> Ahhh I see
[13:46:49] <CaptHindsight> most of the Trinity APU's are supported, Richland is experimental, but it only matters if you want to try coreboot
[13:47:12] <CaptHindsight> the stock EFI works with any FX2 or FX2+ APU
[13:47:50] <lair82_sim> Not a deal breaker, but can you repost that, I just took a 12 guage to my regular desktop
[13:50:05] <pcw_home> but you probaby want a GPU so for cheap the A4-4000 or A4-6300
[14:04:19] <CaptHindsight> http://www.amd.com/en-us/products/pricing/a-series-apu
[14:08:01] <lair82_sim> i just ordered that board and processor, see what happens when it comes in.
[14:12:03] <Jymmm> AB Panel OUCH http://www.ebay.com/itm/Allen-Bradley-Panel-View-Plus-700-Cat-2711P-RDB7C-with-2711P-RP2-Logic-Module-/141303833103
[14:14:46] <pcw_home> A4-4000?
[14:20:52] <CaptHindsight> Jymmm: if I add up the price of the AB Panel View and the AB PLC's in some used machines, the machine is free with those pricey controls
[14:21:17] <Jymmm> CaptHindsight: lol =)
[14:45:20] <CaptHindsight> are there any easy (Win-users) to use control systems for the non-programmer? Something with a graphical menu for controlling stepper motors without coordinated motion. Set distance to move, speed, dwell time etc etc?
[14:46:08] <CaptHindsight> for simple applications like a model train set, small lab gantry, simple pick-n-place etc
[14:46:24] <cradek> sherline sells a pseudocnc rotary table meant for manual indexing
[14:46:37] <cradek> manual gearcutting etc
[14:49:56] <lair82_sim> pcw_home , Yes the A4-4000
[14:51:33] <CaptHindsight> http://www.techno-isel.com/tic/LinearMotionSoftware.htm smells like mach
[14:51:50] <lair82_sim> 3-4 days shipping, so hopefully next week I will have a better idea, on where I am at with things
[14:52:18] <lair82_sim> Talk to you guys tomorrow,
[14:52:27] <CaptHindsight> let us know
[15:06:58] <CaptHindsight> http://www.anaheimautomation.com/products/hmi/color-display-item.php?sID=347&serID=3&pt=i&tID=998&cID=414
[15:07:16] <CaptHindsight> these have a 500 page programming manual
[15:07:49] <CaptHindsight> and are >$1k for anything with a 10" or larger LCD
[15:24:22] <SpeedEvil> CaptHindsight: I've sort-of-been wondering about the same
[15:24:34] <SpeedEvil> (control system)
[15:38:57] <CaptHindsight> SpeedEvil: I don't see much out there. You either need to know G-code or learn some other language to at least setup the UI to make it dumbed down for the user.
[15:39:39] <SpeedEvil> Time for a kickstarter!
[15:39:48] <CaptHindsight> all the touch screen PLC UI's use some proprietary language
[15:40:01] <CaptHindsight> or their tools for setup
[15:40:20] <CaptHindsight> well there is the duino stuff :(
[15:42:11] <CaptHindsight> http://www.instructables.com/id/Guino-Dashboard-for-your-Arduino/
[15:54:23] <FrankZappa> niiiiice
[15:54:31] <FrankZappa> that is going to help me, thank you so much CaptHindsight
[15:54:58] <FrankZappa> you can generate gcode natively though
[15:57:57] <CaptHindsight> FrankZappa: the Gui duino ?
[15:58:10] <CaptHindsight> Guino
[16:00:11] <FrankZappa> yes!
[16:00:14] <FrankZappa> thx
[16:00:21] <FrankZappa> gtg suddenly
[16:35:18] <Deejay> gn8
[17:34:29] <s1dev> anyone have any suggestions for 1/2" shank indexable lathe tools?
[17:47:09] <zeeshan> s1dev: gotta be more specific!
[17:47:20] <zeeshan> are you looking for boring bars?
[17:47:40] <s1dev> good point, anything but boring bars as I already have a nice Dorian one
[17:48:39] <zeeshan> a set
[17:48:43] <zeeshan> is always nice for boring bars :p
[17:49:50] <zeeshan> http://i.imgur.com/EorBvLD.jpg
[17:49:54] <zeeshan> those are most of the tools i use
[17:50:01] <zeeshan> parting tool
[17:50:05] <zeeshan> right hand turning tool etc
[17:50:10] <zeeshan> wnmg holder
[17:50:46] <zeeshan> http://i.imgur.com/afwtMJ7.jpg
[17:50:48] <zeeshan> i cant find a better pic
[17:50:49] <zeeshan> =/
[17:51:28] <s1dev> nice holder
[17:51:45] <zeeshan> thanks
[17:51:49] <zeeshan> it keeps em tidy!
[17:52:13] <zeeshan> heres one you can buy
[17:52:13] <zeeshan> as a kit
[17:53:26] <zeeshan> http://www.ebay.ca/itm/NEW-7PC-CARBIDE-INDEXABLE-LATHE-TOOL-HOLDER-SET-16MM-/400717085135?pt=LH_DefaultDomain_0&hash=item5d4c9979cf
[17:53:42] <s1dev> thanks
[17:54:04] <zeeshan> hm thats .625"
[17:54:41] <Valen> I'm going to give that picture to all my lathe friends
[17:54:59] <zeeshan> which one
[17:55:05] <Valen> http://i.imgur.com/afwtMJ7.jpg
[17:55:22] <zeeshan> its just an angle piec eof aluminum :P
[17:55:35] <zeeshan> you know whats funny
[17:55:38] <zeeshan> i built that first
[17:55:39] <zeeshan> and then i did this
[17:56:08] <Valen> i know its just a bit of angle, but that doesn't mean its not a good idea
[17:56:29] <zeeshan> bah cant find the pic
[17:56:36] <zeeshan> oh here it is
[17:56:37] <zeeshan> http://i.imgur.com/jApkUWQ.jpg
[17:56:42] <zeeshan> i stuck a pole on it
[17:56:49] <zeeshan> so i can mount my monitor
[17:57:04] <zeeshan> it seems to hold it fine so far
[17:57:32] <Valen> nice lathe btw
[17:57:51] <zeeshan> thank you
[17:58:01] <zeeshan> you have a lathe?
[17:59:45] <Valen> yeah, still manual though
[18:56:56] <KimK> pcw_home: I didn't quite follow all of your earlier discussion about motherboards, what didn't you like about the E350's? I have two of them, so I was wondering if there's some problem. They have seemed OK so far, but I've only used them a little, I haven't started using them heavily yet.
[18:57:51] <KimK> So far one running Xenomai, 2nd one for RTAI maybe. If I make more progress, maybe I'll bring them to the Houston fest.
[19:01:01] <KimK> Doing repairs and getting dinner, I'll scroll back later for your comments if any. Thanks!
[19:15:02] <PCW> KimK: nothing wrong with the E350s but the OP was running out of CPU with a Atom and the E350 is not any faster
[19:26:39] <KimK> PCW: OK, I see. Good to know, thanks.
[19:40:38] <MrHindsight> KimK: the E350M's also lack an LPT and PCI slot, they do have #1 PCIe slot and they suddenly are on short supply
[19:42:30] <MrHindsight> we have the E350M1 running 12.04 with 3.4.55 RTAI and hardware accel GPU with 10uS latency with EFI
[20:48:31] <Connor> XXCoder1: The Z would be kinda sucky...
[20:48:33] <Connor> quill only..
[20:48:54] <XXCoder1> yeah thats what I tought. no conversion websites anywhere
[20:49:03] <XXCoder1> and kits is overkill expensive
[20:53:55] <XXCoder1> quill only, tool that cuts? (lathe tool)
[21:06:12] <accuartisans> whois PCW
[21:06:48] <accuartisans> sorry, @PCW you around?
[21:12:08] <pcw_home> yeah
[21:13:30] <XXCoder1> hey pcw
[21:14:44] <pcw_home> Hi XXCoder1
[21:15:58] <accuartisans> hey pcw, I don't know if you remember, I got a Gigabyte board like you have and I finially got it up and running under linux kernel 3.14.4 and Xenomai 2.6.3
[21:17:07] <pcw_home> Thats neat, I have been pretty impressed with the J1800 (for ~10W)
[21:17:23] <accuartisans> I have really good latency results as well. Question what branch are you using to run again your mesa ethernet board?
[21:18:06] <pcw_home> ubc-7i80
[21:18:42] <accuartisans> I did not get the same results you had with rt_preemt, but now that i ahve my bios settings I think I may go back and re-try rt_preemt
[21:19:07] <accuartisans> does that branch support Xenomai?
[21:19:31] <accuartisans> Yes, I amvery impressed with this board
[21:19:49] <pcw_home> Preemt RT-latency is much worse but for hardware stepgens or servos its not terribly important
[21:20:32] <accuartisans> I have Servo Thread(1.0ms) 3630 and Base thread(25.0us) 8125
[21:20:43] <accuartisans> currently:)
[21:21:03] <accuartisans> i had an issue with SMI but that is resolved now
[21:21:26] <pcw_home> I got about 8 usec/8 usec on RTAI without any fussing
[21:21:49] <XXCoder1> damn
[21:21:52] <accuartisans> is usec smaller than ms?
[21:21:53] <XXCoder1> took me while to find https://www.youtube.com/watch?v=_59Kaa92iIk
[21:22:11] <pcw_home> (thats 8000,8000 ns)
[21:22:33] <accuartisans> wow!
[21:22:37] <XXCoder1> accuartisans: https://www.google.com/search?q=1+us+to+ns&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a&channel=fflb
[21:22:53] <accuartisans> dang then I don't know what I did wrong
[21:23:49] <accuartisans> xxcoder1: thanks!
[21:23:56] <pcw_home> Thats RTAI (I think Preemt-RT was maybe 50 usec or so)
[21:24:22] <accuartisans> care to share your image and header.debs?
[21:25:06] <pcw_home> I can get them tommorow (or try to guess the IP address of the test machine...)
[21:26:06] <accuartisans> just looking at RTAI now, what kernel version did you use?
[21:26:29] <pcw_home> I just built the preemt-rt kernel from source (3.12 and 3.14)
[21:27:01] <pcw_home> The RTAI kernel on the live CD works
[21:27:23] <pcw_home> (2.6.32?)
[21:27:46] <pcw_home> No graphics accel of course
[21:28:32] <accuartisans> I think maybe I should send you my bios settings then, cause I bet I have some a miss
[21:28:41] <pcw_home> The 3.4.55 RTAI kernel bolluxes up the video
[21:29:10] <pcw_home> (hoping a 3.12 RTA kernel is not too long in coming)
[21:29:18] <pcw_home> RTAI
[21:29:32] <accuartisans> that's what I was thinking as I found that 3.14 kernel supports the video way better
[21:30:08] <XXCoder1> when will there be new linuxcnc package?
[21:30:11] <accuartisans> also recognizes the processor a little different if my memory recalls
[21:31:01] <pcw_home> Yeah NP watching FS video with linuxcnc running on Ethernet (I think 3.14.5 preemt RT)
[21:31:04] <Valen> pcw_home: any suggestions for how to take internal pcie slots to external?
[21:31:28] <Valen> the latency over ethernet isn't an issue with that? or is that running steppers?
[21:31:47] <pcw_home> for cabled PCIE: 6I71
[21:31:51] <accuartisans> so, i'm looking at www.atai.org... RTAI 4.0 is available but not sure it supports anything latter than 3.8.13
[21:32:11] <pcw_home> NP with steppers over Ethernet
[21:32:24] <pcw_home> or servos
[21:33:18] <pcw_home> only limitation is that theres a fair amout of latency with Preemt RT so that limus the servo thread to about 2 KHz max
[21:33:26] <pcw_home> limits
[21:34:28] <pcw_home> Under Xenomai/RT-Net I suspect 4 KHz or so is possible but you need a RT-net compatible MAC
[21:35:15] <Valen> whats the utility of doing it though?
[21:35:16] <accuartisans> i believe this board is compatible?
[21:35:31] <Valen> of using it over ethernet for RT stuff
[21:35:51] <pcw_home> For velocity mode drives (and hardware stepgens which are effectivel velocity mode drives) 1 KHz is usually fine
[21:38:16] <pcw_home> Valen ?
[21:38:59] <Valen> i mean, why does one want to run RT over ethernet?
[21:39:07] <Valen> realtime stuff over ethernet
[21:39:15] <Valen> just put a computer out there ;->
[21:41:24] <pcw_home> Yeah but thats another computer (and if you have a lot of RT stuff in HAL its got to be a fast computer also)
[21:42:24] <Valen> computers are cheap ;->
[21:45:18] <pcw_home> The other reson for using Ethernet is that its nearly universal and capable of RT
[21:45:48] <pcw_home> and electrically isolated
[21:46:03] <XXCoder1> I plan to use cat5 for limit buttons too
[21:46:26] <Valen> I can see the use for running ethernet, just running realtime over it seems less usefull
[21:46:49] <Valen> i mean if you ran the firmware where your nice fpga's did all the work sure
[21:47:48] <pcw_home> Why less useful? Its a efficient RT connection to external devices
[21:48:26] <pcw_home> beats USB
[21:48:46] <pcw_home> and its almost always available
[21:51:53] <XXCoder1> pcw know anything about Smithy Granite 1340 ?
[21:52:01] <XXCoder1> my uncle has one and wonder if he could make it a cnc
[21:52:21] <pcw_home> Not much other than I have heard of them
[21:53:11] <XXCoder1> its a mill/lathe thing
[21:53:18] <XXCoder1> made me wonder if linuxcnc could do it
[21:54:11] <Valen> linuxcnc can do anything you want it to
[21:54:26] <Valen> its a question of if you can get the machine good enough to be worth it
[21:54:28] <XXCoder1> including build me a cnc so it can run on it? ;)
[21:54:50] <Valen> on a manual lathe/mill the operator can do a lot of fudging to make up for any inadquacies in the machine
[21:55:03] <Valen> when its CnC most of that goes away
[22:00:04] <Valen> so the machine needs to be as good as you can get it
[22:00:19] <XXCoder1> ok
[22:06:11] <jp_mill> XXCoder1: you might want to check out the smithy site the use LCNC for thier machines if i do remember correctly. There is even a config for them in the live CD. not sure if they cnced the granite
[22:06:28] <XXCoder1> yeah saw the kit
[22:06:32] <XXCoder1> riciously expensive
[22:15:35] <CaptHindsight> pcw_home: newer RTAI is waiting for the scheduler to be fixed/updated
[22:16:47] <CaptHindsight> accuartisans: RTAI 4.0 is still a work in progress, not stable
[22:24:18] <accuartisans> capthindsight: newer RTAI? what kernel/patch will that be for I wonder?
[22:27:11] <CaptHindsight> accuartisans: the new development does on at the shabbyx git, then it goes to rtai.org, then that gets tested and starts back over at shabbyx
[22:30:43] <accuartisans> thanks, i was wondering why I saw no repository on rtai.org. So, do you know if a patch is being worked on for linux 3.14?
[22:31:54] <CaptHindsight> the scheduler needs to be fixed to get passed 3.4
[22:34:00] <CaptHindsight> https://github.com/ShabbyX/RTAI/tree/linuxcnc-old was the latest that works with Linuxcnc
[22:34:48] <CaptHindsight> https://www.rtai.org/userfiles/downloads/RTAI/ is the RTAI repo
[22:36:22] <CaptHindsight> accuartisans: once the scheduler gets fixed then 3.10 or 3.14 is possible
[22:36:34] <vit-14> hello i need to buy this sensor how is called
[22:36:49] <vit-14> https://www.youtube.com/watch?v=HZlV4dUuvMI
[22:41:57] <vit-14> capthindsight how is called
[22:42:05] <vit-14> dont see on ebay
[22:42:34] <CaptHindsight> vit-14: that is a touch probe with the plasma torch attached
[22:42:51] <vit-14> how i can do that
[22:44:35] <CaptHindsight> vit-14: this shows how a touch probe works http://fadedbits.com/2011/02/touchprobe/
[22:50:03] <CaptHindsight> vit-14: I don't know what you already have to answer that
[22:50:56] <vit-14> i need a touch probe? or the machine plasma t had
[22:50:58] <CaptHindsight> vit-14: you can also do it by insulating the probe from the machine and using it as the switch
[22:51:51] <CaptHindsight> http://www.youtube.com/watch?v=W1cLGUjUu8I an example
[22:54:06] <vit-14> but with a plasma cutting how can i do im new in that
[22:56:56] <vit-14> capthindsight do you know a sswith thta i can buy on ebay?
[22:58:41] <CaptHindsight> vit-14: most are like this: http://www.ebay.com/itm/Touch-probe-cmm-digitizing-renishaw-haas-fadal-cnc-mill-lathe-router-engraver-/150931049789
[22:59:08] <CaptHindsight> but that's not what you want, the one in the video looks custom made
[22:59:09] <vit-14> im confused
[22:59:58] <vit-14> because how i can have this sensor and the plasma cutting
[22:59:59] <CaptHindsight> I don't know who makes a touch probe like the one in that video
[23:00:05] <vit-14> understand me?
[23:00:18] <CaptHindsight> I'd probably make it myself
[23:00:48] <vit-14> i understand
[23:01:17] <CaptHindsight> http://www.cnc4pc.com/Store/osc/product_info.php?products_id=339?osCsid=9cb438690de2f645e1a951bef1ba4df8
[23:01:28] <CaptHindsight> this is closer to what you want
[23:01:34] <vit-14> when the machine going to cutt needs to use this probe?
[23:02:00] <CaptHindsight> http://www.cnc4pc.com/Store/osc/images/cap04_2%2012.jpg?osCsid=fc5d700f2d6222748bd160c5e4361f0c
[23:02:49] <CaptHindsight> you just need those rings on the probes to be far enough away from the torch tip to not be harmed
[23:03:42] <CaptHindsight> vit-14: the probe just tells you where the surface of the material is, you have to decide when you want to cut
[23:04:00] <CaptHindsight> where and when and what shape
[23:04:18] <CaptHindsight> vit-14: do you have a cnc machine with a torch on it?
[23:04:34] <zeeshan> CaptHindsight:
[23:04:36] <vit-14> im building but omg very difficult
[23:04:40] <zeeshan> can you get those digitizing probes (3d)
[23:04:41] <zeeshan> for cheap?
[23:04:48] <zeeshan> 200$ is the street price that i see ;p
[23:05:57] <Valen> digitizing probe?
[23:06:48] <mozmck> afaik the only really reliable way to sense torch height is to measure the voltage across the gap when cutting.
[23:06:56] <vit-14> no i sure how it work or calibrate the machine when going cutting
[23:07:56] <CaptHindsight> Valen: have you ever seen an stepper controller with an easy to use GUI for non-programmers? Example applications might be small lab gantries, simple pick-n-place etc
[23:08:04] <vit-14> but how in this video is automatic
[23:08:13] <vit-14> https://www.youtube.com/watch?v=HZlV4dUuvMI
[23:08:23] <Valen> nothing springs to mind
[23:08:38] <CaptHindsight> I can't find one either
[23:09:50] <vit-14> but i need to have one? or i can cutting without him?
[23:10:09] <zeeshan> valen its a probe you can throw in a spindle
[23:10:17] <zeeshan> and use to measure coordinates for a part
[23:10:19] <zeeshan> and reverse engineer ;p
[23:10:58] <CaptHindsight> vit-14: if your material is flat then you can just jog the Z axis torch into position and start cutting at the Z position
[23:11:38] <mozmck> vit-14: for initial height sensing you can use a floating head with a mechanical switch. This is probably the most common.
[23:11:46] <CaptHindsight> vit-14: they just wanted to automate that on their cutter
[23:12:36] <mozmck> Ohmic sensor is common and works well, I haven't used the capacitive, but that large ring could get in the way depending on what you are cutting.
[23:12:41] <CaptHindsight> they lower the Z until the switch closes then they know the height of the surface
[23:13:25] <CaptHindsight> yeah the rings aren't ideal
[23:13:40] <mozmck> yes, if you are cutting much of anything you really need the initial height sensing.
[23:13:58] <CaptHindsight> but lower cost than a laser micrometer
[23:14:50] <mozmck> :) higher than a floating head setup though.
[23:15:28] <CaptHindsight> vit-14: is trying to buy something he can just bolt on
[23:15:29] <mozmck> You will find also that if you are cutting anything thin at all a full THC is essential.
[23:15:47] <vit-14> the material is flat
[23:16:09] <mozmck> If it is thin, it won't be flat once you have cut a little bit.
[23:16:24] <mozmck> the heat causes the metal to warp...
[23:16:32] <XXCoder1> unless vacuum held?
[23:16:49] <mozmck> heh, you can try that if you want :)
[23:16:54] <CaptHindsight> XXCoder1: welded to the table below :)
[23:17:11] <XXCoder1> make sure to bolt table to floor too :P
[23:17:44] <CaptHindsight> cast into the concrete so it doesn't move
[23:17:45] <mozmck> I've seen 1/16" plate bow up an inch or so.
[23:17:46] <vit-14> hehe well let me finish that proyect so i need help all
[23:18:56] <CaptHindsight> http://www.razordance.co.uk/THC.htm
[23:19:07] <mozmck> http://www.candcnc.com sells electronics for plasma cutting. ***disclosure: I work for them***
[23:19:17] <CaptHindsight> http://www.ebay.com/sch/sis.html?_nkw=Proffessional%20Compact%20CNC%20Plasma%20THC%20Controller%20Torch%20Height%20Control&_itemId=170940770185
[23:19:39] <vit-14> im crazy, I know nothing about computers, none of these machines and I happened to buy the engines and make one for my work, I hope everything works out.
[23:20:09] <CaptHindsight> that's how you learn
[23:21:36] <vit-14> well its late here talk soon thanks all
[23:21:50] <CaptHindsight> http://www.ebay.com/itm/THC3T-02-Plasma-Torch-Height-Controller-/251542335189
[23:22:40] <CaptHindsight> I don't see the actual probe though
[23:23:13] <CaptHindsight> this must sense the arc
[23:23:58] <CaptHindsight> http://i.ebayimg.com/00/s/MzUzWDY0OA==/z/hXIAAMXQydtTM~MN/$_57.JPG
[23:24:16] <mozmck> It does.
[23:24:32] <vit-14> its good ?
[23:24:44] <mozmck> They copied our screen-set it looks like and changed a few things. :)
[23:25:22] <mozmck> I don't know, but getting support from Vietnam might be interesting :)
[23:26:08] <Aero-Tec> hello
[23:26:19] <Aero-Tec> I have a whack of mach Gcode
[23:26:28] <mozmck> how much is a whack?
[23:26:38] <Aero-Tec> would like to convert it to linuxcnc
[23:27:14] <Aero-Tec> is there a quick and simple program or any info on doing that?
[23:27:45] <Aero-Tec> whack for me, might not be for you guys
[23:28:14] <Valen> gcode in theory shouldn't need conversion
[23:28:15] <Valen> lol
[23:28:32] <Aero-Tec> some where around 50 or so programs, most hand coded
[23:28:39] <Aero-Tec> lol
[23:28:49] <Valen> what do you need to change?
[23:28:56] <Aero-Tec> true, in theory
[23:29:26] <Aero-Tec> I need to get it working on a LinuxCNC unit
[23:29:29] <CaptHindsight> it gets harder when you have 47 custom M codes
[23:29:41] <Valen> what i mean is what changes do you need to make
[23:29:45] <Aero-Tec> so every thing needed to get it running on linuxcnc
[23:30:37] <Valen> gcode isn't "mach" or "linux cnc" it really should "just work"
[23:30:44] <CaptHindsight> Aero-Tec: what happens when you load the programs into the Linuxcnc sim?
[23:31:00] <CaptHindsight> do you get errors?
[23:31:09] <Aero-Tec> it will not load, and linuxcnc has different Gcodes they use and interpret them differently
[23:31:15] <Aero-Tec> like threading
[23:31:30] <Aero-Tec> yes, lots of errors
[23:31:41] <Aero-Tec> then the code will not work right
[23:32:30] <Aero-Tec> I have gone through and fixed errors only to have it do some weird stuff
[23:33:17] <Aero-Tec> was just hoping I could use a converter program and it would work
[23:33:31] <Aero-Tec> wishful thinking
[23:34:48] <Aero-Tec> seeing as I write code and know some things about what is different I might have to write one myself
[23:35:20] <Valen> I'm presuming that sed would do pretty much everything
[23:35:21] <Aero-Tec> thing is it is all old mach code
[23:35:37] <Aero-Tec> not sure if the new version uses the same code
[23:36:20] <Aero-Tec> they are making a new mach program
[23:37:37] <Aero-Tec> I was really hoping not to have to write one, and do all the research into what is different and why
[23:38:57] <Valen> have a look at the errors, most of them are probably going to be setup
[23:39:18] <Aero-Tec> I wish
[23:39:28] <Aero-Tec> way more then that
[23:39:51] <Valen> I would guess that the ones further on follow on from the setup
[23:40:27] <Aero-Tec> I have lathe code and mill code
[23:40:46] <KimK> MrHindsight: Thanks for the info. I must have a different version of E350 than the one you guys were discussing, as mine do have a parallel port, and one standard PCI port. I'm not sure if it also has a PCIe port, let me check. No, just one standard PCI: http://www.gigabyte.com/products/product-page.aspx?pid=4379#ov
[23:40:47] <Aero-Tec> threading is a whole different thing
[23:41:09] <NickParker|2> Hey everybody, I have a 2HP DC spindle, and a spindle controller that's looking less and less likely to ever work. Can anybody point me to a controller linuxcnc can control?
[23:41:37] <NickParker|2> I've only found ones with manual inputs so far (knobs and switches)
[23:41:54] <Aero-Tec> thought linuxcnc can control them all
[23:42:09] <KimK> Hi NickParker|2 , what's the voltage and current of your motor?
[23:42:18] <Aero-Tec> no remote input port?
[23:42:57] <NickParker|2> 12 A currrent, 1500W power, so we can infer ~125V
[23:42:57] <KimK> NickParker|2: I presume you mean your spindle controller is beyond repair?
[23:43:28] <Aero-Tec> they would normally have a port and a way to stop using the local pot and have a 1 to 10 volt, or 1 to 5 volt input
[23:43:34] <NickParker|2> KimK: Well we'll see. It *might* be as simple as a dead SCR. But the whole mill is turning 35 this year.
[23:44:43] <Aero-Tec> thanks for the help
[23:44:49] <Aero-Tec> going to bed
[23:45:40] <NickParker|2> http://www.coleparmer.com/Product/Basic_Variable_Speed_DC_Motor_Controller_for_1_4_to_2_hp_motors/EW-70100-10 This looks like it would work if it had remote input port
[23:46:56] <KimK> NickParker|2: If your controller only has a local pot input, look and see if the controller provides the pot a built in source of +5 or +10 or so across the pot. If so, you might be able to use one of many analog input isolators available (or make your own). Don't skip this step, as many (most) small DC controllers use a hot-chassis design, and don't take well to external 0-10V DC without isolation.
[23:47:51] <KimK> Looking now...
[23:55:58] <KimK> OK, page 23 of the manual ( http://www.coleparmer.com/Assets/manual_pdfs/70100-10.pdf ) says that you can connect an isolated voltage source as from the Minarik PCM4 (or similar) of 0-1.4 (125V) or 0-2.8V (250V) so unusual voltages, but scalable to 0-5 or 0-10 or something.
[23:56:50] <NickParker|2> I'm already using an op amp as a low pass filter to make my 0-10, changing the gain for their voltage range is trivial.
[23:56:54] <KimK> BTW since this is a Minarik drive, you can almost certainly find a cheaper dealer than Cole-Parmer. (I'm just sayin')
[23:57:06] <NickParker|2> please, point me to a cheaper option.
[23:57:12] <NickParker|2> They were just the first google result.
[23:58:28] <KimK> Well, I haven't looked, I just know Cole-Parmer is high. Although probably very convenient one-stop shopping for those with unlimited budgets.
