[00:56:07] <CaptHindsight> I bet this cost way over $1k https://www.youtube.com/watch?v=c3r7lpO8qZI
[01:57:40] <DJ9DJ> moin
[03:16:52] <RyanS> What's a brand of measuring equipment somewhere between Mityutoyo, Starret and cheap ass ebay? ie not absurdly expensive for hobby use but not junk
[06:45:34] <jthornton> RyanS, I think it is all a crap shoot with all the Chinese stuff on the market
[06:46:35] <R2E4> Hi jthornton: IS the LinuxCNC/mesa combination more than a hobby solution? Is it viable for production type VMC's?
[06:46:50] <jthornton> yep
[06:46:53] <cpresser> R2E4: yes
[06:47:37] <R2E4> I have 5i25 and 7i77 boards in hand ready tos tart on my hitachi seiki vm40. but reluctant.
[06:49:34] <jthornton> looks like the biggest hurdle you face is getting over your fear of doing the conversion
[06:50:58] <R2E4> OH, I am doing it. no choice, either that or pay 5,000.00 for hardware/software commercial version. or pay to get existing controller fixed which may or may not work for very long. Its not hard to see what my best choice is.
[06:53:41] <R2E4> I am a little skeprical with programming the plc. There is 8 motors on this thing not including the 3 axis servo and the spindle.
[06:54:05] <archivist_herron> dont worry!
[06:54:13] <jthornton> by plc do you mean classicladder?
[06:54:28] <R2E4> The ladder programming in LinuxCNC
[06:54:59] <R2E4> I am just getting up to speed on the software. I printed the three manuals yesterday and read the getting started cover to cover last nioght.
[06:56:06] <cpresser> R2E4: are all those 8 motors linked? i guess most likely they are for different functions. so just do one at a time :)
[06:56:11] <jthornton> ladder logic is a bit different than programming but not hard to do once you understand the rules
[06:56:22] <jthornton> yep what cpresser said
[06:57:11] <jthornton> the key to ladder is http://linuxcnc.org/docs/html/ladder/classic_ladder.html#_ladder_concepts
[06:57:44] <R2E4> Yeah they are for different functions. Re: coolant, Mist, conveyor, hydraulic pump for hydraulic tool changer etc...
[06:58:20] <jthornton> coolant and mist don't need any ladder they are just outputs
[06:58:38] * cpresser wouldnt use the word 'easy', but does not look to complicated
[06:58:40] <jthornton> when does the conveyor run?
[06:58:44] <R2E4> If I leave it up to manual energizing of these aux motors and pumps, I wont need the logic, I can just manually start them.
[06:59:13] <R2E4> So the ladder is used for logic? Make things happen when and/or when other things happen?
[06:59:50] <jthornton> iocontrol.0.coolant-flood is connected to your output for flood similar for mist
[06:59:57] <R2E4> ITs a chip conveyor at the bottm of the bed, when chips are flying they drop to bottom in the screw area that ships the chips out.
[07:00:05] <cpresser> R2E4: yes. assume you have a pressure-sensor. "if pressure < threshold then start hydraulics pump."
[07:00:31] <jthornton> yes the ladder is logic, timers, counters etc.
[07:00:33] <R2E4> I would suppose I would need the ladder when it comes to the tool changer.
[07:01:05] <cpresser> either ladder, or a hal-component. depends on what you like more :)
[07:01:32] <cpresser> logic can also be done with a python-userspace-hal-component (toolchangers are not that fast)
[07:02:15] <R2E4> ITs a ways to go before I reach that point.
[07:02:33] <jthornton> I use ladder for my tool changer and my way lube pump
[07:03:55] <R2E4> I use automationdirect d06 and d05's plc's at work, so ladder logic I understand.
[07:04:28] <R2E4> for creating lab door interlocks and such.
[07:06:24] <R2E4> Do most vmc's have seperate switches for homing and limit?
[07:07:01] <jthornton> mine does
[07:07:21] <R2E4> I know my bridgeport does, but not sure about this machine.
[07:07:40] <jthornton> if your familiar with ladder then classicladder should be a cinch
[07:08:23] <jthornton> for homing with servos you normally use a switch and the index from the encoder
[08:32:09] <R2E4> Any other boards like the beagle board but with RS485 uarts ?
[08:35:01] <jdh> there are rs485 capes for BBB
[08:36:06] <jdh> or maybe they are just planned. You could always add a converter
[09:34:33] <R2E4> Well it is more on the permanent side. I need two or three and the only cape has one.
[09:40:48] <jdh> design your own multiport one.
[09:42:02] <jdh> or use one of these: http://www.moxa.com/product/NPort_5430.htm
[09:48:45] <ssi> multiport 485 cape for BBB wouldn't be terribly hard
[09:57:34] <R2E4> The whole point of the rs485 was to daisey chain boards, the device server is networked and therefore why daisey chain if network is available.
[09:58:30] <jdh> I have quite a few rs485 devices here. None are multi-
[09:59:09] <R2E4> multi-?
[09:59:23] <R2E4> port?
[09:59:31] <jdh> multidrop
[09:59:50] <CaptHindsight> NPort 5430 Series 4-port RS-422/485 serial device servers, Jikes! it's $406!
[10:00:09] <jdh> I think that is the price for the 232 version
[10:00:15] <jdh> 485 is more
[10:00:47] <CaptHindsight> 4-port RS-422/485 device server $565.00
[10:00:58] <jdh> there ya go!
[10:01:12] <jdh> I have a few of their single port rs232 ones.
[10:01:17] <R2E4> The beagle is not really expensive, so I need to hang 16 rs485 devices of each one then that would work.
[10:01:19] <CaptHindsight> 12 x the BBB, seems about right
[10:01:23] <jdh> and some ethernet-IO ones
[10:02:04] <R2E4> So I could go with one rs485 on each then.
[10:03:55] <CaptHindsight> you could get old $50 PC's and rs485 adapters for less
[10:08:26] <CaptHindsight> R2E4: 16 rs485 in a daisy chain or?
[10:09:19] <R2E4> daisy chain with each there own address.
[10:10:15] <CaptHindsight> ethernet to 2x 422/485 servers are ~$60ea
[10:11:53] <R2E4> Thats a bulky way to do it no? I have devicess allready built that 16 devices connects to and it upstreams data on rs485.
[10:13:32] <R2E4> it goes: Device (addr 1-16) < wireless > -> panel <=> BeagleBoard
[10:14:27] <R2E4> This is allready done..... used OEM devices. I need to now design and manufacture my own devices.
[10:14:31] <CaptHindsight> BBB has 4 serial ports at either 3V or 5V
[10:15:33] <R2E4> rs232only?
[10:15:47] <CaptHindsight> looks like 3.3V, not rs232
[10:16:00] <R2E4> ah...
[10:16:09] <CaptHindsight> http://circuitco.com/support/index.php?title=BeagleBoneBlack#BeagleBone_Black_Features
[10:16:30] <R2E4> I seen that..... no good.
[10:17:10] <jdh> what do you want to speak to?
[10:17:23] <CaptHindsight> can't use a 3.3V serial to rs485 converter?
[10:17:29] <R2E4> there are however rs485 transceivers tat 3.3v
[10:18:30] <R2E4> I want to limit the conversion processes. 16 devices on the line can get quite busy
[10:19:41] <CaptHindsight> did I miss something? you have 1 BBB and a 16 device rs-485 network or?
[10:20:19] <R2E4> 1 BBB and I want to connect 16 rs485 devices to it.
[10:22:05] <CaptHindsight> a converter won't slow anything down
[10:22:19] <R2E4> The devices are allready developed, I basically want to create a web driven frontend to it, and expand it by having several BBB that talk to the master database BBB
[10:22:43] <jdh> a BBB opc server
[10:22:54] <CaptHindsight> heh, probably best if you have a drawing up somewhere to look at
[10:25:03] <R2E4> I got several hanging around. I'll locate one after I eat. I'm famished!
[10:30:28] <ssi> I think the bbb has six uarts?
[10:35:11] <CaptHindsight> http://circuitco.com/support/index.php?title=BeagleBoneBlack#BeagleBone_Black_Features
[10:35:38] <CaptHindsight> ssi: your guess is as good as mine when this is how they post the specs
[10:36:35] <CaptHindsight> written like they were bothered to write this
[10:37:24] <CaptHindsight> or "what you want from us for only $45?"
[10:45:59] <R2E4> http://www.irmtl.com/BBB/BBB-1.pdf
[10:52:05] <Aero-Tec> is there a way to fill a variable value with the location of a axis?
[10:52:16] <Aero-Tec> in Gcode
[10:53:37] <Aero-Tec> I have Gcode that runs through a sub several times, and is using G91 moves for the the A axises
[10:54:00] <Aero-Tec> I would like to read the value of it if possible
[10:54:08] <jdh> sure
[10:54:29] <archivist> I tend to decide myself what my variables hold I therefore decide what holds what rather than read current values
[10:54:45] <jdh> http://www.linuxcnc.org/docs/html/gcode/overview.html#_numbered_parameters_a_id_sub_numbered_parameters_a
[10:54:48] <Aero-Tec> true
[10:57:09] <CaptHindsight> R2E4: BBB serial 3.3V --> RS485, cheap, simple, fast
[10:57:40] <Aero-Tec> very cool
[10:57:42] <Aero-Tec> thanks
[10:58:18] <CaptHindsight> R2E4: http://circuitco.com/support/index.php?title=BeagleBone_RS485
[10:59:06] <R2E4> ah cool. Thanks
[11:06:03] <CaptHindsight> https://www.inventables.com/technologies/desktop-laser-cutter
[11:17:41] <cbjamo> pcw_home: You arround?
[11:25:18] <cbjamo> Or, Does anyone have a working 7i39 .hal file i can use for reference? I feel like I'm missing stuff, but don't know enought about hal to be sure.
[11:26:01] <Aero-Tec> (AXIS,show) did not stop the need for the esc button press on load
[11:26:53] <Aero-Tec> guess the planner runs through the code and checks it
[11:27:09] <Aero-Tec> if the code never ends then it gets stuck
[11:27:36] <Aero-Tec> not a big deal
[11:28:54] * Loetmichel had to make his tools thns morning to work (43mm holder for the hand drill to grind off paint from Computer parts) -> http://www.cyrom.org/palbum/main.php?g2_itemId=14298&g2_imageViewsIndex=1
[11:29:17] <Loetmichel> ... sometimes its very convenient to have a small CNC mill handy ;-)
[11:31:28] <JT-Shop> cbjamo: are you using pncconf to generate your configuration file?
[11:32:39] <cbjamo> JT-Shop: I started with that, but I've had to modify it pretty exstensivly, I'm using ja3, as I have 2 motors per axis, and I have one 7i39 per channel.
[11:33:08] <JT-Shop> I doubt you will find a config to match that, what are you missing?
[11:34:08] <cbjamo> JT-Shop: thats the thing, I don't know enough to know what I'm missing. I'm just looking for a single 7i39 that is fully configured, so that I can compare to something.
[11:34:28] <JT-Shop> just generate one using pncconf
[11:35:20] <pcw_home> Theres someone on the mailing list using a 7I39 (propcoder) maybe he can help
[11:35:56] <cbjamo> pcw_home: Which mailing list, user or dev?
[11:43:21] <pcw_home> users
[11:44:15] <pcw_home> and of course Andy when he's available but he's probably having fun at the LinuxCNC shindig
[11:57:16] <Jymmm> pcw_home Heh, you should of grabbed cases of cards and went yourself =)
[12:02:30] <pcw_home> I am going
[12:03:08] <Jymmm> pcw_home: Bringing cases of cards?
[12:06:03] <pcw_home> I am bringing a few cards
[12:06:59] <Jymmm> pcw_home: Brings cables too =)
[12:07:45] <Jymmm> pcw_home: Nothing worse than buying a new toy and can't use it becasue of a 50¢ damn cable
[12:08:58] <cradek> pcw_home: stuart says sure you can ship stuff here. do you need the address?
[12:19:36] <IchGuckLive> hi all B)
[12:25:24] <pcw_home> I can probably google it a a known correct address would be better
[12:25:40] <pcw_home> s/a a/but a/
[12:31:20] <cradek> pcw_home: would you bring me a 7i30 please? ideally the connectors too if you can...
[12:33:01] <Jymmm> pcw_home: ...and a cheeseburger.
[12:33:38] <pcw_home> OK
[12:33:43] <cradek> thanks!
[12:34:04] <R2E4> Where is thi LinuxCNC shindig....?
[12:34:12] <cradek> Wichita KS USA
[12:34:18] <Jymmm> R2E4: BFE
[12:34:46] <R2E4> BFE?
[12:34:48] <IchGuckLive> Jymmm: no chunk food
[12:35:13] <IchGuckLive> ej its upper hot africa like temoeratures here in germany
[12:35:31] <IchGuckLive> and obama is on the way to berlin
[12:35:32] <chesepuff>
[12:39:39] <PetefromTn> Afternoon Folks...
[12:39:54] <IchGuckLive> evening PetefromTn
[12:40:18] <PetefromTn> LOL hey ICh..
[12:40:43] <IchGuckLive> linuxcnc has 34/7
[12:40:46] <IchGuckLive> 24
[12:40:54] <IchGuckLive> B)
[12:41:00] <PetefromTn> yup sure does
[12:41:43] <IchGuckLive> i did 12 frech install today as some did fail on first education lesen yesterday
[12:42:53] <PetefromTn> Sitting here drawing in Freecad a project for a customer and doing it on my NEW cherry desk with a nice hutch that has my favorite KRK rockit studio monitor speakers on it. They are enough to blur my vision sitting here rockin out to REO speedwagon LOL.. Life is good!
[12:43:35] <IchGuckLive> generate some money
[12:43:41] <archivist> music worth wearing ear defenders
[12:44:11] <PetefromTn> yup!! exactly...
[12:44:57] <PetefromTn> I cannot believe how nice this setup is here. My kids are playing on their WII and I can relax and concentrate on the drawings..
[12:45:31] <PetefromTn> Bob Marley sounded especially good..
[12:45:53] <PetefromTn> ;P
[12:46:26] <archivist> you got nothing decent?
[12:46:37] <PetefromTn> You got no taste?
[12:46:53] <PetefromTn> What do you suggest I got TONS of music here
[12:47:25] <jdh> rachmaninoff piano concerto no.2
[12:47:37] <archivist> Pink Floyd saucer full of secrets
[12:47:55] <jdh> or that
[12:48:07] <Tom_itx> pcw_home, also the address is in this thread: http://thread.gmane.org/gmane.linux.distributions.emc.user/42692/focus=42699
[12:48:11] <PetefromTn> I like the Division bell and delicate sound of thunder got both..
[12:48:15] <archivist> see if the speakers can handle the organ section
[12:48:39] <Tom_itx> in stuart's 2nd post
[12:48:46] <PetefromTn> These KRK's simply ROCK<<<<
[12:49:05] <archivist> I believe my uncle is in the choir on that bit
[12:49:31] <PetefromTn> No kiddin' ... Awesome.... My favorite PF tune is the Great GIG in the sky...
[12:49:43] <IchGuckLive> Stevie Nicks nothing more needed only power vioce
[12:50:00] <PetefromTn> Stevie is AWESOME...and kinda sexy too..
[12:50:04] <archivist> and one pink floyd connection collects adjustable spanners
[12:50:46] <IchGuckLive> she can bee mot of us mother
[12:50:57] <PetefromTn> Listenin to Papa Roach...forever right now. KICK ASS SOng..
[12:52:11] <IchGuckLive> he has been last week around here in germany
[12:52:28] <PetefromTn> Really Starting to get the hang of freecad. It is very usable.. Really hope they get it to be a stable program and get the Cam packages going soon.
[12:52:33] <IchGuckLive> http://www.youtube.com/watch?v=qViSviEs5_I
[12:52:34] <Tecan> (qViSviEs5_I) "Papa Roach Live At Rock Am Ring 2013 HD 720p" by "Ne3rino" is "Music" - Length: 0:43:36
[12:52:37] <PetefromTn> Oh yeah...Cool.
[12:53:21] <IchGuckLive> PetefromTn: ask awallin he dioes the stuff
[12:54:26] <PetefromTn> does what stuff?
[12:54:53] <IchGuckLive> cam implementing to freecad
[12:55:03] <IchGuckLive> based on opencamlib
[12:56:22] <PetefromTn> Sweet. It is so far the easiest to use 3d cad package I have tried but it is not without bugs as it is still in beta.
[12:57:50] <IchGuckLive> agree but got drawing stuff
[12:58:07] <IchGuckLive> as heekscad doesent
[12:58:25] <IchGuckLive> qcad and heekscad is nice to work also
[12:58:45] <PetefromTn> never got heeks downloaded right never tried qcad either.
[12:59:09] <PetefromTn> If this can get UNbuggy it will be everything you need really.
[12:59:12] <IchGuckLive> qcad is autocad12
[13:00:16] <PetefromTn> I been using Draftsight for autocad clone...works great.
[13:00:45] <IchGuckLive> i use this in one lesen to show straight forwad construction (@22.5<45
[13:01:41] <IchGuckLive> and sheetcam demo for the CAM to it
[13:02:07] <PetefromTn> I like sheetcam got it paid too...
[13:03:08] <IchGuckLive> its worth every cent
[13:03:41] <willburrrr2003> Hi all, i am getting ready to try to get spindle rpm feedback going. I am planning on an index pulse and an encoder pulse. Can i get thr speed feedback with just the indez pulse? i dont have the second sensor mount finished, but want to make progress if i can...
[13:04:07] <PetefromTn> yup....going to play with CamBam here too...
[13:06:58] <IchGuckLive> willburrrr2003: parport ?
[13:08:00] <willburrrr2003> yes I am using a parallel port interface
[13:08:06] <IchGuckLive> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Closed_Loop_Spindle_Speed_Control
[13:08:29] <lwizardl> hello
[13:08:35] <IchGuckLive> B)
[13:09:22] <IchGuckLive> lwizardl: how is the weather ?
[13:09:59] <willburrrr2003> Ichgucklive, thanks opening link now...
[13:10:11] <IchGuckLive> NP
[13:10:12] <lwizardl> if I was looking for an application to do both electronics and designing the housing for the electronics. what linux app would be able to do both ?
[13:10:33] <lwizardl> IchGuckLive: not too hot out yet
[13:10:50] <IchGuckLive> eagle got a case cam
[13:11:15] <IchGuckLive> but its only boxing the pcb
[13:11:16] <archivist> eagle has limits
[13:11:50] <archivist> kicad does not have limits and also has a 3d view
[13:11:55] <lwizardl> yeah i was looking at eagle and geda so far
[13:13:14] <lwizardl> what i am wanting to do for example say I want to design a wireless controller for a game system, I want to be able to build the casing around the electronics
[13:13:20] <PetefromTn> That Rachmaninoff concerto is sweet...
[13:13:43] <IchGuckLive> im off by
[13:13:50] <PetefromTn> cya ich..
[13:20:55] <Willburrrr2003> Ichgucklive, thanks for that. It was a great read for info. I had not considered a PID loop, but it makes sense as it has to maintain commanded speed under varying cutting load conditions
[13:25:37] <Willburrrr2003> From reading, when i get the sensor installed for the encoder pulses, do i need 100 pulses per rev, I made my encoder disc last year befor I really understood the requirements....my disc has one index pulse and 39 encoder pulses...is it scrap, or can i still use it?
[13:27:42] <pcw_home> 39 slots should be fine for a spindle encoder
[13:27:52] <willburrrr2003> webclient through smartphone....not to stable lol
[13:28:30] <willburrrr2003> good enough for threading operations?
[13:28:37] <pcw_home> Yes
[13:30:24] <willburrrr2003> thats great news, good to know the time making it was not wasted , though either way it was a good learning experince generating my first gcode made part
[13:30:40] <jdh> what material is the disc?
[13:30:40] <pcw_home> you need quadrature (A,B) for rigid tapping though
[13:31:07] <Tom_itx> pcw_home, any luck compiling that pin file?
[13:31:35] <willburrrr2003> yes, i understand that....but with my minilathe not sure i can switch directions with the spindle running...
[13:31:50] <pcw_home> No its a genuine bug, I need to track it down sine the error message is not too illuminating
[13:32:11] <Tom_itx> so should i hold off on that card and get the other one?
[13:33:19] <Tom_itx> i don't _need_ either one but wanted to move the io off the bare port
[13:33:22] <pcw_home> I woudl wrry about getting it to compile its possible it must just be some corner condition (There are more than 100 PIN files and Ive never seen that error before)
[13:33:33] <pcw_home> wouldn't worry
[13:33:52] <pcw_home> I will track it down
[13:34:02] <Tom_itx> i'm in no hurry
[13:34:09] <Tom_itx> and will probably show friday
[13:34:15] <Tom_itx> AM
[13:34:45] <pcw_home> I will end up there late Friday night (well late for us old folks)
[13:34:55] <Tom_itx> oh
[13:35:04] <Tom_itx> well i may be on the way to KC late friday
[13:35:48] <pcw_home> I am really there just for the weekend
[13:38:29] <Tom_itx> if you need room for other stuff then let mine go as we may not cross paths there then
[13:47:00] <PetefromTn> This is the first thing I have ever seen printed with a 3d Printer that was actually really cool and looked smooth and clean... Impressive. http://www.youtube.com/watch?feature=player_embedded&v=VrJadl6zqz4
[13:47:01] <Tecan> (VrJadl6zqz4) "ODD 3D printed guitar first sound test" by "oddguitars" is "Music" - Length: 0:08:10
[14:17:32] <CaptHindsight> PetefromTn: SLA and SLS prints can be very smooth with few micron features, it's the glue gun types that look like lumps of pasta
[14:21:33] <skunkworks> CaptHindsight: tell us what you really think ;)
[14:21:58] <JT-Shop> lol
[14:28:50] <pcw_home> Mmm pasta. Good for food printing though, not sure I wold like photopolymerization initiators in my food
[14:29:32] <CaptHindsight> pasta is an actual good fit for 3d printing with extruders
[14:30:06] <CaptHindsight> polymers, not so much
[14:30:10] <Tom_itx> pcw_home, unless i could make arrangements to leave payment and have you leave the card and pick it up the following week
[14:30:26] <Tom_itx> unless you'd rather not do that
[14:30:51] <pcw_home> I can do that
[14:33:07] <PetefromTn> CaptHindsight: Interesting, and I am sure those models are the PRICEY ones of course LOL.
[14:34:08] <pcw_home> They are mechanically simple and should be inexpensive
[14:34:29] <CaptHindsight> PetefromTn: the raw material cost is lower, but they have been selling them for more
[14:35:22] <CaptHindsight> "It's the patents, stupid." ™
[14:35:43] <PetefromTn> I hope someone builds a cool extrude head setup I can bolt to my VMC so I can play too... Otherwise I cannot see building one unless it is just for fun.
[14:38:32] <CaptHindsight> PetefromTn: you can buy just the heater, extruder and nozzles
[14:38:53] <pcw_home> Seems like all the basic patents would have run out
[14:38:55] <pcw_home> photopolymer tech is pretty ancient
[14:38:56] <CaptHindsight> complete assemblies, but most are pretty crude
[14:39:04] <PetefromTn> To do work like that guitar?
[14:39:51] <CaptHindsight> is there an up close pic of the guitar?
[14:40:30] <CaptHindsight> pcw_home: 3d systems filed an infringement suit against form1 a few months ago
[14:40:42] <PetefromTn> Anyone know why Windows media player cannot be just like other apps that allow you to reach the start menu bar without minimizing, its annoying when I want to go from draftsight or freecad to WMP and back...
[14:40:57] <PetefromTn> I only have that video..
[14:42:37] <jdh> try alt-tab
[14:43:48] <pcw_home> Heck images in photopolymers go back to Niepce
[14:44:03] <pcw_home> (1820s)
[14:44:40] <CaptHindsight> tell that to the patent office
[14:45:18] <CaptHindsight> there are patents on how you separate the cures layer from the vats as well as how you project and with what device
[14:45:26] <CaptHindsight> cures/cured
[14:46:36] <PetefromTn> jdh: Thanks but is there no way to make it the same as the rest of the apps that you can just move to the edge with the cursor and bring up the hidden start menu bar?
[14:47:09] <CaptHindsight> it's a mess designed to keep those with the largest legal warchest happy
[14:47:22] <CaptHindsight> it breeds laziness
[14:47:26] <pcw_home> Theres even a separate patent for printing Chocolate
[14:47:47] <PetefromTn> mmmm Chocolate....
[14:47:51] <Connor> I'm sick of the Patent laws..
[14:48:07] <Connor> Glade they ruled that a company can't own a "Gene"
[14:48:10] <pcw_home> I a lot of cases really nothing more than a protection racket
[14:48:14] <CaptHindsight> the system has been abused
[14:48:20] <gene78> Guys, got a problem with G33.1, or at least a question. Does it issue the spindle reverse command without an intervening stop?
[14:48:40] <gene78> And as you can gues, nobody owns this "Gene"
[14:48:51] <PetefromTn> Hell I do...LOL
[14:49:04] <PetefromTn> Papers are in the mail..
[14:50:40] <CaptHindsight> that was a nice surprise from SCOTUS on blocking patents for discovering genes
[14:51:44] <PetefromTn> Anyone here mess with linkedin? I keep getting invites and dunno if it is BS or not....Yeah I know OT.
[14:52:10] <CaptHindsight> PetefromTn: it's like a Facebook for business connections
[14:52:11] <gene78> It does help, considerably. LinkedIn? I run like hell...
[14:52:20] <JT-Shop> gene78: the spindle has to stop to reverse... the Z will stay in sync with the spindle
[14:52:31] <Connor> It's Facebook for businesses
[14:53:09] <PetefromTn> Yeah I know maybe I'll give it a shot..
[14:53:11] <JT-Shop> I think linkedin is spam as it invites you without the person knowing
[14:53:26] <PetefromTn> That's what I was thinking exactly
[14:54:17] <CaptHindsight> if you're trying to find a contact it can be of some help
[14:54:33] <gene78> But does it actually issue the stop? My driver has a return to zero lockout, which is disabling the driver till a reset, near zero volts, has been output by the controller
[14:54:42] <CaptHindsight> but it's full of noise and marketing types that use it as a blog
[14:54:57] <Connor> PetefromTn: Might not hurt to join it.. Get your name out there so people know that you can do custom machine work etc..
[14:55:07] <gene78> so the driver locks out, and I am truning the synchronized spindle by hand ;-)
[14:55:36] <PetefromTn> Connor: Yeah man I am thinking about it..LOL
[14:55:47] <CaptHindsight> lots of people just post job listings or their new services or products
[14:56:09] <Connor> gene78: I don't know.. I just know that it g33.1 works. :)

[14:56:23] <Connor> I wouldn't think it would issue a stop command through.
[14:56:45] <JT-Shop> stop what?
[14:57:30] <Connor> g33.1
[14:57:30] <Connor> If it issues a stop command before the reverse.
[14:57:30] <JT-Shop> stop command for what?
[14:57:30] <gene78> I ran it from the mdi and it seemed to work a couple of times, but put it in a loop and boom, lcnc froze.
[14:57:30] <JT-Shop> spindle?
[14:57:30] <Connor> JT-Shop: yes.
[14:57:45] <JT-Shop> please read this http://www.linuxcnc.org/docs/html/gcode/gcode.html#sec:G33_1-Rigid-Tapping
[14:57:45] <gene78> A stop command to the spindle, this one is not a servo
[14:58:20] <JT-Shop> no it does not stop the spindle
[14:58:47] <Connor> Mine isn't either.. I'm using a SCR speed controller with a reversing module. uses a relay.. not exactly the fastest at changing direction.. but, it works.
[14:59:00] <PetefromTn> JT-Shop: What the hell is that the dumbest song in the world?
[14:59:47] <JT-Shop> uh, no but it does have modivational value if you listen to the words LOL
[15:00:04] <PetefromTn> LOL crackup..
[15:00:26] <gene78> Got it in front of me. So I guess my .hal file will have to grow a stop on reverse command. Damn. My reversing is an m5 stop, m4, but the m4 is locked out by hal logic until the spindle has actually stopped as indicated by a timeouton the encoder pulses.
[15:01:04] <JT-Shop> Ya can't roller skate in a buffalo herd
[15:01:04] <JT-Shop> But you can be happy if you've a mind to
[15:01:18] <gene78> At 100 rpm, in mdi it works, at 100 rpm in an .ncg script, boom.
[15:01:22] <JT-Shop> All ya gotta do is put your mind to it
[15:01:22] <JT-Shop> Knuckle down, buckle down do it, do it, do it
[15:01:25] <Connor> gene78: Why do you have it locked out ?
[15:02:15] <gene78> Safety freature of the driver, so it will not start up at some abitrary speed after a power failure,
[15:02:50] <skunkworks> gene78: I don't think it matters.. As long as the spindle reverses - rigid tapping doesn't care.
[15:03:30] <gene78> And its a very strong controller, 25 amps, to a 9 amp 1HP motor. A direct reversal could clear the 9 amp breaker
[15:03:33] <JT-Shop> gene78: will M4 reverse the spindle when running in M3?
[15:03:46] <gene78> lemme trry
[15:04:54] <gene78> works but only 2-3 times before something triggers the lockup.
[15:05:36] <JT-Shop> ouch
[15:06:05] <gene78> And it works directly, so it wouldn't be at all safe for more than 100 rpm, its a quite noticable jerk
[15:06:33] <Connor> gene78: You have a breaking resistor ? and is this a VFD ?
[15:06:34] <gene78> Looks like I go back to carving a new hal file. Grrr.
[15:07:32] <gene78> Braking R yes, C41 controller driving a Century Electronics pwm driver. Dead silent

[15:47:35] <Guest73270> Hi guys, has anyone got experience running linuxCNC with a laser?
[15:48:37] <PetefromTn> Like Buck Rodgers? JK...
[15:50:15] <CaptHindsight> Guest73270: working on one now, using servos and galvos
[15:51:13] <Guest73270> I'm currently dithering images, using DotG to generate the Gcode but as you can imagine the motion is jittery. Is there a way to get smooth motion left and right?
[15:52:05] <CaptHindsight> Guest73270: how are you driving your mirrors?
[15:52:10] <Guest73270> Sorry, I'm using M64/65 to fire the laser
[15:52:31] <Guest73270> The mirrors are fixed
[15:55:10] <JT-Shop> I think there was some discussion on the forum or mailing list about firing lasers
[15:55:10] <CaptHindsight> Guest73270: how do you generate motion?
[15:55:11] <Guest73270> Sorry, with steppers connected through parallel breakout
[15:55:11] <skunkworks> Guest73270: have you read http://www.buildlog.net/forum/viewtopic.php?f=16&t=557&sid=8567d51d4ee04319e13e21b7b4108f83
[15:55:12] <sharpen047> anyone cut vinyl with a cnc mill? not a deticated vinyl cutter? i cant find any info on overlapping cuts in linux cnc or mastercam
[15:55:12] <Guest73270> I have, and there was a discussion about using an addon for engraving. But I'm new to linux and the machine is strictly offline so I'm not sure how to get the files to the machine
[16:08:20] <Guest73270> https://github.com/jv4779/2x_laser/blob/master/README.md <-- this is the raster addon, How would I install this from USB?
[16:12:24] <Tom_itx> download the files as a zip and run as a local install?
[16:12:28] <Tom_itx> not sure...
[16:15:40] <CaptHindsight> Guest73270: what do the steppers move since the mirrors are fixed?
[16:16:38] <Guest73270> Sorry, I meant the mirrors sit on a gantry, 1 mirror is fixed.
[16:16:38] <DJ9DJ> gn8
[16:16:47] <CaptHindsight> ah ok
[16:20:59] <skunkworks> Guest73270: no way you can hook to the internet?
[16:21:36] <Guest73270> Nope :( Workshop is too far away and its embedded(never thought it through) in the machine
[16:22:07] <skunkworks> you need to be able to sudo apt-get install linuxcnc-dev build-essential
[16:22:28] <skunkworks> I don't know how you do this without internet.. I am sure you can - but I don't know how
[16:23:10] <Guest73270> Damn, even after doing this I need to figure out how to use it :P
[16:32:20] <archivist> these days help is a a click away on the web and a connections is so useful
[16:38:30] <JT-Shop> I just picked up the reversing tapping head from the other shop. Can I tap at 600 RPM in steel with it? I've always used 250 or so when rigid tapping on the VMC...
[16:38:47] <PetefromTn> I just picked up one of those small USB wireless jobs for the VMC for such an instance...
[16:39:03] <JT-Shop> I have to start drilling and tapping on the BP CNC knee mill
[16:39:18] <JT-Shop> tired of the 308 drive tripping out
[16:39:18] <cradek> are you asking about surface speed or the capabilities of the tapping head's reversing mechanism?
[16:39:30] <JT-Shop> surface speed
[16:39:54] <cradek> what's the speed at your diameter?
[16:40:09] <JT-Shop> the tapping head lists up to 2000 RPM
[16:40:16] <cradek> woo
[16:40:23] <cradek> better have a depth stop
[16:40:43] <JT-Shop> 3/8-16 is 600 RPm
[16:41:07] <JT-Shop> the BP is CNC but no feedback on the spindle yet
[16:42:18] <Tom_itx> JT-Shop, as long as you can set your depth at that speed :)
[16:42:45] <JT-Shop> what do you mean set my depth?
[16:42:51] <Tom_itx> we ran similar to those on manual machines pretty quick
[16:43:01] <Tom_itx> how deep you let the tap go into the hole
[16:43:12] <JT-Shop> it will be in the G code
[16:43:21] <Tom_itx> ours were spring loaded
[16:43:47] <Tom_itx> so the'd snap a bit if they retracted too quick
[16:44:11] <Tom_itx> test run it in wood :)
[16:44:56] <JT-Shop> this one has about 1/2" of extension, not sure how far I'll have to go to get it into reverse
[16:45:31] <tjb1> Hello JT-Shop and Tom_itx
[16:46:17] <JT-Shop> hi tjb1
[16:46:21] <Tom_itx> i think ours were a bit different though since they were on a lathe
[16:46:33] <Tom_itx> they would speed up to enter the hole
[16:46:42] <JT-Shop> Tom_itx: it has some hints about tapping with CNC
[16:46:57] <JT-Shop> this one is the same speed in and out
[16:47:09] * Tom_itx smells dinner
[16:47:16] <Guest73270> Just found my wifi adapter, but it never worked last time(too far) so I'm going to put it on a usb extension.
[16:47:22] <Tom_itx> right
[16:47:26] <tjb1> JT-Shop: You would not believe how many collets go through hardinge in a day

[17:14:22] <Tom_itx> JT-Shop what triggers the reverse mechanism on it?
[17:15:05] <JT-Shop> when you pull up on it the shaft extends a bit then shifts to reverse
[17:15:55] <Tom_itx> so you push it down to depth then start to retract and it should reverse?
[17:16:43] <JT-Shop> yes it does reverse as soon as you start to pull up
[17:16:53] <Tom_itx> what's the reverse ratio?
[17:17:17] <JT-Shop> this one is 1:1
[17:17:20] <Tom_itx> you don't wanna retract too quick or too slow
[17:17:23] <JT-Shop> some are 1:2
[17:17:34] <Tom_itx> ours were spring loaded so we had some leeway
[17:17:49] <JT-Shop> this one is spring loaded as well
[17:18:05] <Tom_itx> we just tried not to let them pop too hard
[17:18:11] <Tom_itx> on exit
[17:18:25] <JT-Shop> yea, I know what your talking about
[17:18:34] <Tom_itx> sometimes on the manual machines we were somewhat limited on the cams we could use
[17:18:40] <JT-Shop> we used this on the manual Enco for a few years
[17:19:08] <Tom_itx> and had 5 other stations being driven at the same time so had to balance out everything
[17:19:38] <JT-Shop> sounds too much like fun
[17:21:58] <JT-Shop> I have a 1.300" hole in the spindle shaft at the top, any ideas on how to mount a shaft in that to take an encoder?
[17:22:09] <JT-Shop> tight fit and locktite?
[17:23:44] <cradek> JT-Shop: you could make two pieces that lock inside the hole like a bicycle stem
[17:24:19] <cradek> get a close fit, cut in two at an angle, drill the top one through oversized, tap the bottom one
[17:24:28] <Tom_itx> or run a setscrew thru the shaft to hold it in place
[17:24:32] <JT-Shop> ok that makes sense
[17:24:35] <Tom_itx> thru the tube
[17:24:47] <JT-Shop> no side access to the tube
[17:24:50] <Tom_itx> k
[17:25:17] <cradek> or use a cone that pulls into a slotted and matching taper - that will stay centered better
[17:25:27] <Tom_itx> that was my next suggestion
[17:25:42] <Tom_itx> like a draw bar holds a collet in place
[17:25:50] <cradek> yeah
[17:26:18] <JT-Shop> yea, that would make it simple to mount an encoder to the BP spindle
[17:26:32] <JT-Shop> and I happen to have one laying about somewhere
[17:26:35] <cradek> or just turn your plug with a slight taper, drop it in there from a foot up and call it good
[17:26:52] <JT-Shop> lol
[17:26:55] <cradek> turning an encoder wheel doesn't take much...
[17:27:00] <JT-Shop> you know I can't do that LOL
[17:27:43] <Tom_itx> the drawbar might be your best bet in case you need to remove it
[17:27:57] <Tom_itx> then you can knock the slug out of the way and it will release
[17:29:00] <JT-Shop> this is the spindle drive http://imagebin.org/261828
[17:29:21] <cradek> do you need a drawbar coming through this?
[17:29:37] <JT-Shop> no it is a Kwik Swith spindle
[17:29:43] <JT-Shop> Switch
[17:29:57] <Tom_itx> what are you gonna mount the sensor to?
[17:30:02] <JT-Shop> with indexable holders like Cat etc
[17:30:05] <Tom_itx> and.. hall or ir?
[17:30:07] <cradek> yeah
[17:30:30] <JT-Shop> well there are three jacking holes that are not doing much most of the time in the black part
[17:30:52] <JT-Shop> Tom_itx: I have a 2500 line encoder
[17:31:05] <Tom_itx> i see an overengineered project in thw works
[17:31:17] <JT-Shop> LOL, you know me too well
[17:31:59] <Tom_itx> if there's room, i'd put a small shoulder on the top half to rest on the bronze looking tube
[17:32:30] <Tom_itx> then hold it with it's inside taper pulled tight with the slug
[17:32:31] <JT-Shop> no room the id of the black part is about the same as the bare steel tube
[17:33:04] <Tom_itx> well make your sensor height adjustable then
[17:33:42] <JT-Shop> what if I put some O-Ring grooves in the shaft, the friction from the O-Rings should turn the encoder
[17:33:54] <JT-Shop> but I need some kind of down stop for that
[17:34:09] <Tom_itx> it's not just a wheel you want to mount but a shaft encoder?
[17:34:14] <JT-Shop> I could bore out the black part a bit
[17:34:26] <JT-Shop> aye, a shaft encoder
[17:34:42] <Tom_itx> heck, just use a rubber stopper then with a hole in the middle
[17:34:44] <JT-Shop> I have the encoder and coupling
[17:36:26] <JT-Shop> I think I can have spindle feedback by lunch... YEA!
[17:43:39] <Tom_itx> i thought you were mounting a wheel to the top for a homebrew encoder at first...
[17:46:16] <JT-Shop> found it http://imagebin.org/261830
[17:46:50] <Tom_itx> i've got a few like that but probably smaller
[17:46:52] <Tom_itx> 500 count
[17:46:55] <Tom_itx> x 4
[17:47:21] <Tom_itx> was looking for an image but can't locate it
[17:49:46] <R2e4_1> .4 millisecond is a decent latency result?
[17:50:56] <JT-Shop> 10,000 ns is great but it just depends on everything
[17:51:48] <R2e4_1> its servos so hopefully it will be ok.
[17:52:27] <PCW> .4 milliseconds is really not good enouigh
[17:52:31] <JT-Shop> are you sure it is .4 ms
[17:53:23] <JT-Shop> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Latency-Test
[17:53:34] <R2e4_1> yeah, settings in bios could fix it? or get it closer?
[17:54:11] <JT-Shop> R2E4: what was the max jitter from the latency test in ns
[17:54:51] <R2e4_1> the maual says .4 ms is ok. 1ms forget it .1 is really good
[17:55:27] <R2e4_1> that was in the store i did it with the guy. i will try it at home.
[17:56:08] <uw> hmm
[17:56:23] <R2e4_1> does it make a diff if i have the 5i25 in or not?
[17:57:10] <R2e4_1> the guy wanted to shoot me, i tried 6 diff boxes......
[17:57:14] <JT-Shop> are you sure it was .4 millisecond not .4 microsecond?
[17:59:42] <R2e4_1> no not 100% sure, but yeah.
[18:00:20] <JT-Shop> 1000 times different lol
[18:01:11] <R2e4_1> im 40%sure....hehe
[18:01:58] <JT-Shop> best to use the units that the latency tests reports in
[18:03:23] <JT-Shop> PCW: what's a good latency when using pci cards?
[18:03:42] <R2e4_1> yeah sorry, .4milliseconds
[18:05:39] <PCW> anything better than 50 usec is probably OK
[18:07:09] <PCW> .4 ms (400 usec) would only allow a < 500 hz servo thread
[18:07:33] <PCW> (without getting real time errors)
[18:08:30] <R2e4_1> thats depressing
[18:09:12] <JT-Shop> you don't need a powerhouse gaming computer for CNC
[18:09:55] <R2e4_1> its not new, it was used 4 core 4 gigs ram
[18:10:16] <R2e4_1> i will try my box and see what i get
[18:10:39] <Guest73270> I use an old celeron laptop :P
[18:10:42] <JT-Shop> for multi core you many times need to isolate one core for real time
[18:11:22] <R2e4_1> in bios?

[18:15:07] <PCW> Tom_itx: looks like an obscure Xilinx bug
[18:17:53] <PCW> workaround is to set synthesis 'Optimization goal' to speed instead of area
[18:22:37] <PCW> really really dig them buggy tools
[18:22:39] <PCW> AFAICT 2 deep async read dprams are not synthesized correctly in optimize area mode
[18:22:40] <PCW> so if sserial channels are <3 you need to optimize for speed (which is OK)
[18:44:41] <sharpen047> can someone help me with cutter compensation? i just added a swivel vinyl blade onto my cnc mill
[18:45:13] <JT-Shop> we just ask the question around here not if someone can help
[18:45:26] <JT-Shop> if someone comes by that can answer they will
[18:46:12] <sharpen047> well im not exactly sure what to ask. it doesnt adjust for a swivel blade.
[18:46:30] <sharpen047> i have fengrave, mastercam and other free software
[18:46:39] <JT-Shop> I thought the swivel blade just follows?
[18:47:09] <JT-Shop> or do you have to turn the A axis to keep it perpendicular to the cut path?
[18:47:43] <sharpen047> right but if it stops heading in the west position then i start cutting down from the north the straight line now has a swivel in it. it also doesnt cut at the center so it doesnt cut the whole letter out
[18:47:57] <sharpen047> its a 3 axis
[18:48:39] <skunkworks> I really don't think cutter comp will adjust for a draging blade...
[18:49:39] <skunkworks> cutter comp is for offseting for a tool diameter.
[18:52:38] <sharpen047> vinyl cutting software adjusts for it but there isnt a 'driver' for my cnc
[18:54:39] <skunkworks> you are going to have to explain your proccess
[18:55:44] <jdh> you need a tangential knife
[18:58:21] <Tom_itx> PCW, i'll try it again
[18:58:39] <Tom_itx> i'm pretty good at breaking stuff
[18:59:53] <Tom_itx> so can i still get by with 1 channel or do i need 2?
[19:00:12] <skunkworks> https://www.youtube.com/watch?v=GqRy9XU4uWs
[19:00:43] <sharpen047> jdh: where would i find a tangential cutter?
[19:01:32] <jdh> afaik, they are fairly pricey. You coudl make one
[19:02:05] <Tom_itx> cnc drag knife
[19:02:52] <jdh> sounds like he has a drag knife setup
[19:03:16] <jdh> http://www.axyz.com/us/cnc-knife-systems/
[19:04:13] <jdh> a servo spindle would probably do the same thing?
[19:05:25] <jdh> http://www.rockcliffmachine.com/forum/attachment.php?attachmentid=485&d=1297734681
[19:05:40] <jdh> stepper with a shaft mounted knife holder
[19:06:09] <atom1> PCW, where do i change those settings?
[19:06:12] <PCW> 2 sserial channels minimum
[19:06:14] <PCW> its a lot of work to support just 1 channel because of all the degenerate cases:
[19:06:15] <PCW> RAM inference and decoders go bad for example
[19:06:34] <atom1> i'll leave it as is then
[19:08:03] <PCW> if you right click on synthesize and select properties, it the top menu item
[19:08:42] <atom1> found it
[19:09:35] <atom1> runnign
[19:09:49] <uw> does anybody use CNC equip to remanufacture bullets?
[19:09:55] <uw> I'm thinking about doing it
[19:10:06] <uw> but looking for ideas
[19:10:23] <uw> (aka shamelessly stealing ideas)
[19:10:44] <uw> for my own personal use though, i wont be selling bullets or anything
[19:10:49] <atom1> idk but i found some old ww2 tooling in the tool crib where i worked once
[19:10:53] <atom1> 50cal
[19:10:59] <atom1> casing tools
[19:11:02] <PCW> good artists borrow, great artists steal
[19:11:15] <atom1> and never get caught
[19:11:20] <Jymmm> uw: reloads or ???
[19:11:39] <uw> thats cool atom did they have shell dies or anything?
[19:12:02] <atom1> no these were for turning the casings
[19:12:02] <uw> Jymmm, yes reloads. primarrly 223 and 308 as i have about 10k cases from each
[19:12:22] <Jymmm> uw: so you have the spent brass aleady?
[19:12:29] <jdh> uw: you could send me a few hundred 223
[19:13:14] <uw> yes and i have reloading equip, however I'm looking to automate the process becuase it takes me alot of time because i have to do each one by hand
[19:13:21] <Jymmm> uw: you want to smelt the lead too?
[19:13:37] <uw> Jymmm, i would be ok with just using federal premade bullets
[19:14:04] <uw> jdh, lol maybeee are you willing to contribute to the CNC reloader?
[19:14:05] <Jymmm> uw: Manually, how's the primer "reloaded"?
[19:14:18] <jdh> get a dillon and an air cylinder
[19:14:32] <Jymmm> uw: press fit?
[19:15:13] <uw> Jymmm, I have a lee press and the die kit i have has a punch out tool to remove the old. then the primer seat has to be cleaned (i use this debur type tool) and press another primer in
[19:15:24] <uw> that would be something i would like to automate too
[19:16:01] <Jymmm> uw: I think I'd want an extra shield when inerting the new primer =)
[19:16:09] <Jymmm> uw like 2" thick =)
[19:16:13] <atom1> PCW, how did you come across that error / bug?
[19:16:24] <PCW> google
[19:16:31] <jdh> dillon 650 is almost automatic as is.
[19:16:36] <Jymmm> uw: http://www.youtube.com/watch?v=WLU6NRonDLY
[19:16:37] <Tecan> (WLU6NRonDLY) "Simple .223 primer crimp removal" by "roknrandy" is "Howto" - Length: 0:03:26
[19:17:32] <uw> Jymmm, most of the cases i have arent crimped in
[19:17:38] <Jymmm> ah
[19:17:51] <uw> but still, the seats need to be "touched up"
[19:17:59] <Tom_itx> PCW, how do i find out what pins the encoder etc functions are mapped to on the 7i84?
[19:18:17] <PCW> I think i had set the mode to area at some point (trying to cram in a config that barely fit) and forgot it
[19:18:30] <uw> which is cleaned out using hand tools and that's a pain. It would be cool if i could have a machine do this work
[19:18:54] <Tom_itx> i'm gonna start a hal file for it
[19:18:58] <PCW> which 7I84 pins? thats in the 7I84 manual
[19:19:06] <Tom_itx> ok
[19:19:16] <Tom_itx> getting ready to print that
[19:19:21] <Jymmm> uw: I think it be straight forward using a carousel of sorts
[19:19:45] <Tom_itx> PCW, is the syntax in there as well?
[19:19:54] <jdh> you would need to separate case prep from loading
[19:19:55] <Tom_itx> i'll look over the logs... i think it was mentioned once
[19:20:04] <Jymmm> uw: Larger hopper to align, drop int he carousels, and go from there
[19:20:05] <uw> Jymmm, agreed.
[19:20:42] <uw> i think i could have this done by now if i had some industrial arms to play with
[19:20:59] <PCW> I forgot what the encoder count is named
[19:21:02] <Jymmm> uw: intergrate a gram scale to weight each load, etc
[19:21:24] <jdh> grain scale
[19:21:54] * Jymmm smacks jdh with a WHATEVER! =)
[19:22:29] <uw> lol
[19:23:04] * Jymmm replaces jdh's helium tank with CO tank.
[19:40:59] <atom1> PCW, i get a 212490 byte TopEPPHostMot2.bit file
[19:41:41] <atom1> does it generate an xml or is that even needed?
[19:47:30] <PCW> No xml (pncconf is the only thing that uses the xml file)
[19:49:36] <atom1> looks like there's a bit involved in setting up the sserial
[19:53:53] <PCW> not really, it should just work
[19:54:35] <PCW> only thing needed is to set the remote mode (if you use the encoder inputs)
[19:54:56] <Tom_itx> i don't need to worry about the software mode?
[19:55:09] <Tom_itx> reading about the mpg's
[19:55:16] <Tom_itx> software mode 3
[19:55:30] <PCW> yes you need to set one that has encoders if you want them
[19:55:50] <Tom_itx> i need one for the mpg since i'll be moving that over to this card eventually
[19:55:58] <Tom_itx> the rest is gpio
[19:56:06] <PCW> thats a token in tje config string in the ini file
[19:56:42] <Tom_itx> is hostmot2 in the integrators manual?
[19:57:04] <PCW> man hostmot2
[19:57:10] <Tom_itx> i did that
[19:57:39] <Tom_itx> i was gonna print the sserial part in winders
[19:58:11] <PCW> sserial_port_0=3x
[19:58:27] <Tom_itx> most of it is directed toward the 5i25 :)
[19:58:32] <Jymmm> PCW: Hey, need a 36" plotter?
[19:58:52] <Jymmm> PCW: FREE http://sfbay.craigslist.org/sby/zip/3879710375.html
[19:59:08] <Jymmm> PCW: 650C, not 6500
[19:59:48] <PCW> Nice but I dont need one
[19:59:58] <Tom_itx> boat anchor?
[20:00:20] <Jymmm> Posters, schematics, diagrams, maps, etc
[20:00:31] <Jymmm> inkjet, not pen based.
[20:00:41] <PCW> I have a more serious boat anchor plotter (Versatec 3600)
[20:01:12] <PCW> probably weighs 900 lbs
[20:03:05] <Jymmm> PCW: That's it?
[20:03:32] <PCW> sserial_port_0=3x
[20:03:33] <PCW> note the x to disable the second port so its not probled
[20:04:10] <atom1> if it were used would it be sserial_port_0=33?
[20:04:47] <PCW> if you wanted the mode on the second port to be 3
[20:04:54] <atom1> right
[20:06:01] <PCW> normally if not used you want it disabled or the TXpin will rattle around at startup which might be a bad thing
[20:06:13] <atom1> yeah
[20:07:21] <PCW> if x-ed its usable as GPIO
[20:07:30] <Tom_itx> oh
[20:07:50] <PCW> (like all other FPGA pins)
[20:07:51] <Tom_itx> i was gonna ask if it was just along for the ride since it was part of the sserial 00
[20:08:33] <PCW> no, all hostmot2 configs allow any pin to be GPIO
[20:11:07] <PCW> the driver is not quite so flexible since modules are enabled by selecting the number of modules you want enabled
[20:17:54] <atom1> is that andy's handiwork?
[20:20:22] <Tom_itx> is there a pdf somewhere for the hostmot2 man?
[20:55:15] <CaptHindsight> http://www.mhzelectronics.com/ebay/andrea/mab.jpg anyone know a good source for an air bearing like this only with 300mm of z travel?
[20:56:39] <toastydeath> Ouch
[20:56:44] <toastydeath> that's going to be expensive
[20:57:04] <CaptHindsight> yeah
[20:57:19] <toastydeath> does it have to be a box way?
[20:57:59] <CaptHindsight> I want to mount a pan and tilt on top without the z-axis getting in the way
[20:58:22] <toastydeath> if you get some centerless ground stock you can make your own
[20:58:37] <CaptHindsight> might have to
[20:59:18] <toastydeath> if you're trying to do pan and tilt that takes care of panning
[20:59:19] <CaptHindsight> looking at a 5-axis setup with pan and tilt on top
[20:59:23] <toastydeath> Oh, nvm
[20:59:30] <toastydeath> thought this was for something else
[21:00:00] <CaptHindsight> the tool is mounted stationary over the stage
[21:00:52] <CaptHindsight> I can raise the whole stage as a platform as well
[21:01:07] <CaptHindsight> using two linear motors
[21:03:32] <CaptHindsight> http://www.hsintekoptics.com/pdt/parts/5axis_stage.jpg the pan and tilt can't be mounted on this type of z-axis
[21:21:01] <Jymmm> OH GAWD this is nice... I can burn an iso from the nas box directly now =)
[21:21:05] <Jymmm> NAS --> LAN --> iMac --> USB_DVD_DRIVE
[21:23:23] <atom1> PCW, does this look right for sserial on pin 4, 6, 20 & 21?
[21:23:40] <atom1> of course the board isn't present...
[21:29:23] <CaptHindsight> nice 5-axis tilt table @ 0:49 https://www.youtube.com/watch?v=PWJAeEzqdc4
[21:31:00] <atom1> woops, forgot the link: http://tom-itx.dyndns.org:81/~webpage/cnc/configs/sherline/bitfiles/dmesg.txt
[22:59:46] <eric_unterhausen> CaptHindsight: we have one of those centroid tilt tables at work. I have never really been impressed, it has the minimum structure possible to still do the job.
[23:00:27] <eric_unterhausen> I like the idea of putting a lathe on the bed of a mill. Too bad the little Chinese lathes are such pieces of junk
[23:20:41] <CaptHindsight> eric_unterhausen: our application is no contact and the parts are under 4lbs
[23:20:55] <CaptHindsight> non contact
[23:22:09] <CaptHindsight> it's funny, lots of US and Euro machine tools are actually made in China, but they have to set high QC standards for their suppliers or they end up with junk
[23:24:21] <CaptHindsight> and for all the glue gun fans http://www.3ders.org/articles/20130618-build-your-home-with-a-makerbot-it-would-take-220-years-to-3d-print.html
[23:33:52] <RyanS> Is a live centre only necessary if you machining really heavy parts?
[23:36:31] <cradek> a live center is convenient but I don't know if it's ever really necessary
[23:37:02] <cradek> you have to keep a dead center oiled and keep an eye on it, but that's no big deal
[23:38:39] <roycroft> yeah, a live center is only needed if you're lazy :P
[23:39:56] <roycroft> and a crappy live center can have some runout
[23:41:13] <cradek> yes for the most careful work a dead center will win
[23:41:28] <roycroft> a carbide tip dead center
[23:48:27] <RyanS> I have a spindle dead centre but I don't think, that has a carbide tip (althougonly if turning between centres)
[23:50:14] <cradek> the spindle side one turns with the spindle so it makes no sense to have a bearing in it
[23:50:47] <cradek> and I suppose you don't need any of carbide's benefits either
