[02:18:38] <Deejay> moin
[02:22:56] <TurBoss> morning
[02:23:18] <TurBoss> Deejay: can you helpme with a python component ? is very easy
[02:23:32] <TurBoss> I can't figure where is the fail
[02:23:39] <TurBoss> http://dpaste.com/0C772SF
[02:23:43] <TurBoss> http://dpaste.com/31ND4Y3
[02:24:02] <TurBoss> it turns on but no off
[02:24:05] <TurBoss> :)
[02:24:45] <Deejay> nope, sorry, no idea of python and that stuff :/
[02:24:56] <TurBoss> thx
[02:31:40] <archivist> use one pastebin, dont forget when testing to check a value of a pin, add comments to your code so people know what you think it does
[02:32:05] <archivist> that last bit helps you also fis your own code :)
[02:32:06] <TurBoss> okay
[02:32:59] <archivist> I too am a python free zone
[02:33:50] <archivist> and I hate to see infinite while loops in any code
[04:46:11] <XXCoder> TurBoss: should commet ALL code, even if its your eyes only
[04:46:50] <TurBoss> :)
[04:46:57] <TurBoss> i fount the issue i think
[04:49:38] <TurBoss> prev_value = copy.copy(actual_value=
[04:49:40] <TurBoss> )
[04:49:57] <TurBoss> it works
[04:50:04] <TurBoss> :) now time to comment
[04:50:49] <XXCoder> nice
[05:24:48] <jthornton> morning
[05:28:19] <XXCoder> yo
[05:41:52] <Deejay> hey
[06:26:42] <Tom_itx> morning..
[06:28:26] <jthornton> yo
[06:31:51] <jthornton> there must be a way other than static ip to make the nas be on all the time...
[06:33:44] <XXCoder> jthornton: mac address reservations
[06:33:46] <Sync> tell your dhcp server to give your nases mac always the same ip
[06:33:51] <jdh> you can usually tell your dhcp to give the same address
[06:34:12] <_methods> yeah what they sadi
[06:34:16] <_methods> s/sadi/said
[06:34:20] <jdh> heh... I'd just do static though
[06:34:49] <jthornton> the nas acts wonky if you give a static ip and won't back up the computers
[06:35:23] <jthornton> let me see if I can remember which one is the dhcp server...
[06:35:32] <_methods> your router usually
[06:35:53] <_methods> unless you set up a separate computer to be your dhcp server
[06:36:35] <jthornton> no, just a router and 2 switches
[06:37:23] <jthornton> need to go out to the shop and find the log in info
[06:37:24] <_methods> well then your router is mostly likely your dhcp server unless you've configured otherwise
[06:37:48] <_methods> time to head in to work
[06:37:50] <_methods> blech
[06:38:06] <XXCoder> hey
[06:38:09] <XXCoder> and later lol
[06:48:04] <Jymmm> jthornton: It's called "persistent dhcp", where the dhcp server (your router) will assign/reserve the same ip address to the same device (MAC address) each time.
[06:51:03] <Jymmm> What *I* do, is split the subnet in half; The lower half (1-127) I reserve for static IP's (printer, etc), the upper half (128-254) I set as my dhcp pool. This allows one to have the same full subnet across the whole lan, and still have the best of both worlds.
[06:52:17] <Jymmm> This is using a /24 ( or subnet mask.
[06:54:02] <XXCoder> I usually use sub 1-10 for network stuff, 11-99 for perment ips and above that for dhcp
[06:56:25] <Jymmm> 001-099 for network, 100-127 for testing/hosts, 128-254 for dhcp. That way I can always remember that 100+ is "available" to much around with, or even 050+ without conflict.
[07:11:17] <jthornton> well that seemed to work, the nas is now on
[07:11:29] <XXCoder> laters and nice
[07:12:05] <jthornton> it says DHCP IP Address Range 100 199
[07:12:23] <jthornton> DHCP Lease Time 10080 minutes
[10:04:35] <witnit> Im terrible at some things. I got this digitax st drive from control techniques, bought some insanely overpriced cable to communicate with it. It refuses to connect. I would assume I should just be able to apply 24vdc to the drive and communicate with it. It's not really plausable that I would have to apply 3 phase to the drive as well to communicate with it right? or no?
[10:08:09] <archivist> what does the FM say
[10:08:32] <witnit> fm?
[10:08:44] <archivist> firkin manual
[10:09:02] <witnit> it doesnt say shit
[10:09:07] <witnit> it has a picture
[10:12:53] <Deejay> mojn
[10:13:23] <witnit> moin!
[10:15:10] <Deejay> :)
[10:17:51] <CaptHindsight> http://www.sdrive.sk/_Data/ct/digitax/Digitax%20ST%20User%20Guide%20iss1.pdf
[10:18:06] <CaptHindsight> http://www.emersonindustrial.com/en-EN/documentcenter/ControlTechniques/PDF/H-DigitaxST.pdf
[10:19:42] <CaptHindsight> I'd reckon that it needs ALL the power before it communicates, but the manual doesn't mention it
[10:25:50] <MacGalempsy> good morning
[10:27:05] <MacGalempsy> jthornton: you around? I downloaded your turret sim and have a few questions
[10:38:30] <witnit> archivist, CaptHindsight: Thank you both for input :) apparently I had everything correct but the software was calling for a default node of "11" and I tried putting "01" and it connected. how the hell was I even supposed to figure that out from the manual
[10:39:00] <witnit> quickshart guide is poopy
[10:39:04] <CaptHindsight> mind reading skills
[10:39:39] <CaptHindsight> the dev at Emerson knows how to do it, damn you for also wanting to know
[10:40:53] <witnit> honestly though the quick start setup page was a single diagram no words, just a diagram.
[10:47:48] <witnit> Gooooooood morrrnin MacGalempsy
[11:00:11] <MacGalempsy> whats going on witnit?
[11:00:19] <MacGalempsy> making anything cool yet?
[11:02:08] <witnit> YES :)(
[11:04:43] <witnit> this guy just mailed me 20K worth of electronics for a prototype machine which needs to be ready for IMTS
[11:05:03] <witnit> im all sorts of excited
[11:06:02] <CaptHindsight> is there any cash in the box?
[11:06:36] <witnit> i never get to use new parts :P all my builds have always ever came from scrap heaps and ebay UNABLE TO TEST lots. :)
[11:08:30] <witnit> nah, the money will come after the success
[11:12:43] <witnit> I had to FCKGW-RHQQ2 the whistler to make ends meet. I been hooked on linux without any other OS in the house for quite a few years now. quite the flashback no BSOD yet tho!
[11:13:48] <CaptHindsight> do you get to keep the parts either way?
[11:14:06] <witnit> I keep the knowledge gained and contacts met!
[11:14:18] <CaptHindsight> so you are working fro free
[11:14:22] <CaptHindsight> fro/for
[11:14:42] <CaptHindsight> at least that is how they see it
[11:15:57] <MacGalempsy> all that electronics mumbo jumbo is chinese to me. what kind of machine are the electronics hooking up to?
[11:16:43] <witnit> I like to look at it like an investment but yeah definately working it for free right now
[11:16:45] <CaptHindsight> with no skin in the game a potential client will just walk away at a whim
[11:17:14] <CaptHindsight> so don't be surprised if they do
[11:17:20] <witnit> its for this servo drilling machine
[11:17:31] <archivist> I am fed up with free
[11:18:03] <archivist> I might retire early and get a pay rise
[11:18:14] <CaptHindsight> they will still treat you like they have paid you and if anything goes sour they just walk
[11:19:56] <witnit> oh yeah for sure, but the opportunity alone is incredibly valuable to me. The potential for financial freedom through this field of work is very attainable.
[11:20:20] <CaptHindsight> they should still be paying you something up front
[11:20:31] <witnit> He offered I told him no.
[11:20:37] <CaptHindsight> they take advantage of your willingness to do anything for free
[11:20:50] <MacGalempsy> Confucious say, never turn down free money!
[11:21:25] <CaptHindsight> sounds like a gambler
[11:21:53] <MacGalempsy> witnit: perhaps he can sell your services to potential clients, since you will already have the knowledge
[11:22:29] <CaptHindsight> what they hear is, "I work for free and I'm worth every penny"
[11:23:25] <CaptHindsight> the reason some large co's hire unpaid interns is because they can, they have a line of people that are dreamers that will work for free
[11:24:11] <MacGalempsy> well, in all honesty, interns dont know shit, I was one a few times.
[11:24:15] <witnit> yeah good luck finding a line of people who can use, linux, and industrial controls, with a background in machining
[11:24:35] <CaptHindsight> all the moreso you should be getting paid
[11:25:01] <CaptHindsight> I see people take advantage of open source devs all the time
[11:25:17] <MacGalempsy> true dat, I never interned for free >)
[11:25:51] <CaptHindsight> they just suck from open source and nothing gets contributed back
[11:26:46] <CaptHindsight> they feel that they are superior to you and that they deserve it
[11:29:26] <CaptHindsight> that is why reprap has so many scammers
[11:29:40] <gregcnc> This guy shipped 20k of gear and doesn't want to pay for time?
[11:30:09] <CaptHindsight> he offered to pay, but witnit refused
[11:30:25] <CaptHindsight> living dangerously
[11:30:30] <gregcnc> Oh, um everyone makes choices
[11:30:47] <gregcnc> hopefully some well written contracts invovled
[11:31:17] <CaptHindsight> I'm only providing another perspective
[11:32:24] <witnit> money doesnt motivate me much either, I suppose if I needed it badly I would have taken him up on the offer but it would be such a small amount comparatively it would make me very little difference. My intentions are to create job security and more customers in my line of production work. If I charged him 50K whats good is that? last me a year or two?
[11:32:31] <CaptHindsight> I've had people send me $10's of K's of equipment but not pay their bills
[11:33:09] <gregcnc> capthindsight exactly
[11:33:35] <witnit> the machines these controls are built for are 1.5mil bare
[11:34:12] <CaptHindsight> charge them $50k and if you don't need it fund some project that does
[11:34:30] <CaptHindsight> it's frozen otherwise
[11:34:31] <MacGalempsy> more of a linuxcnc question... the turret ATC I have has an encoder on the shaft. I do not see a direct method to match the encoder with classic ladder for tool # position. How would I go about setting up a routine to match encoder position to a signal name?
[11:35:22] <MacGalempsy> which linuxcnc file would it go to? a python script perhaps?
[11:35:42] <CaptHindsight> obsessive money collectors freeze their financial power, they don't use much of it
[11:36:12] <gregcnc> witnit you have some commission from these future sales then?
[11:36:16] <CaptHindsight> you might ague that by holding on to it they use it to borrow
[11:36:56] <Tom_itx> MacGalempsy have you looked at andy's carousel comp?
[11:37:12] <MacGalempsy> not aware of such a thing. link?
[11:37:22] <Tom_itx> linucnc docs
[11:37:27] <MacGalempsy> ok
[11:37:34] <Tom_itx> what ver are you running?
[11:37:37] <CaptHindsight> witnit: I could use some free help, interested? :)
[11:37:41] <Tom_itx> it was fairly recent
[11:37:47] <MacGalempsy> at the moment none. the computer wont be here until friday
[11:38:12] <MacGalempsy> I have it running on a virtual drive
[11:38:33] <MacGalempsy> i think is is 2.74
[11:42:07] <Tom_itx> http://linuxcnc.org/docs/2.7/html/man/man9/carousel.9.html
[11:42:53] <MacGalempsy> Tom_itx: you deserve a kiss
[11:42:58] <MacGalempsy> not from me though
[11:43:29] <Tom_itx> andy wrote it, kiss him :)
[11:46:36] <Tom_itx> he has a demo of it somewhere
[11:47:34] <MacGalempsy> just getting to the pins section
[11:49:18] <witnit> gregcnc: yeah, I told him I would only work for a % of sales on machines and whatever on site rates I would impose to customers who need older machines retrofit. (every machine is a bit different and needs old PLC tech to be in communication with the new controls voltages, hardware, connector types and drawings vary tremendously over the last 50 years and honestly I dont see very many people with that broad knowledge in this field)
[11:52:33] <CaptHindsight> they are around just in other lines of work now
[11:53:05] <CaptHindsight> Used machines and retrofits are really down right now
[11:53:15] <witnit> down?
[11:53:19] <CaptHindsight> at least in the US
[11:53:25] <CaptHindsight> sales
[11:53:32] <CaptHindsight> business
[11:53:45] <witnit> well, these arent lathes and mills
[11:53:58] <witnit> this work never goes away
[11:54:43] <Tom_itx> MacGalempsy, http://thevideos.us/watch/PfZwpjUs1xI
[11:57:09] <MacGalempsy> the rotation is right, but mine uses 3 pneumatic actuators :p
[11:57:33] <Tom_itx> visit with andy about it
[11:57:54] <Tom_itx> he might be eager to mod it or help...
[11:58:18] <MacGalempsy> he has helped out in the forum, so I'll hit him up in there
[12:01:01] <MacGalempsy> so pocket basically is a tool holder position number?
[12:02:28] <MacGalempsy> that makes more sense. I cannot imagine someone having more than one carousel on a machine
[12:03:33] <archivist> look on yooootoooob there are some :)
[12:05:03] <MacGalempsy> so the this component looks right up my ally. Thanks again Tom_itx
[12:05:28] <witnit> I anyone is still concerned about me making money feel free to run my auctions way up on these spiral taps i have ;) http://www.ebay.com/usr/justinkf
[12:05:57] <CaptHindsight> no, I just want your free help that others get :)
[12:06:02] <gregcnc> lol, there you go
[12:06:39] <MacGalempsy> just post an auction for that 20k in electronics :)
[12:06:46] <witnit> capt if its in my realm of capability and feel good when I do the work it usually is free
[12:06:57] <MacGalempsy> for $15 and send a link to the guy who sent them to you.
[12:06:59] <witnit> hahaha I could have gone on ebay and bought used for a 5th the price :)
[12:08:17] <witnit> I give all my machine junk to a buddy and let him ebay it for me, 50/50
[12:09:24] <Tom_itx> MacGalempsy, pocket and tool# could be different as is true on alot of machines
[12:09:31] <CaptHindsight> why even volunteer? I'd spend my days at the beach machining
[12:09:44] <Tom_itx> in shorts and sandals?
[12:10:08] <CaptHindsight> over my smartphone
[12:10:28] <CaptHindsight> making Yodas for the underprivileged
[12:17:22] <MacGalempsy> make sure your coolant levels are up
[12:35:33] <CaptHindsight> so a 6i25, 7i77 and LPC card + BOB to run this stupid SLA printer
[12:42:49] <CaptHindsight> 2 servos and 2 steppers
[12:44:51] <CaptHindsight> isn't the 7i33 a 4 channel servo?
[12:46:38] <CaptHindsight> are there any Mesa IO cards that combine analog servo with steppers?
[12:46:51] <CaptHindsight> pcw_home: ^^^
[12:47:42] <CaptHindsight> PCW_ ^^
[13:01:28] <pcw_home> for analog servos that that probably the easiest
[13:01:29] <pcw_home> there are no convenient step/dir/analog servo combos
[13:01:48] <pcw_home> s/that that/that's/
[13:01:52] <CaptHindsight> thanks
[13:02:21] <CaptHindsight> from the BOB data sheet "All the signals are opto-isolated which can protect your computer security."
[13:02:22] <pcw_home> a 7I85S + 7I83 is another possibility
[13:02:30] <SpeedEvil> lol
[14:34:42] <Computer_barf> sup folks
[15:17:36] <CaptHindsight> the newer tb6600 stepper drivers are surprisingly quiet
[15:19:30] <CaptHindsight> http://www.valuehobby.com/tb6600-controller.html $12
[15:20:33] <CaptHindsight> but I wouldn't use them for anything fast without a few component additions
[15:20:55] <CaptHindsight> it's missing mostly decoupling caps
[15:59:12] <Tom_itx> out of stock
[15:59:49] <CaptHindsight> what is a good way to run a stepper motor that is not controlling an axis but will run for say 200 steps every few operations? It should easily drop into G-code
[16:00:21] <CaptHindsight> Tom_itx: they should be back in stock soon
[16:00:28] <CaptHindsight> I got the last few they had
[16:00:47] <Tom_itx> make a user defined M code for it to run a few steps
[16:01:02] <Tom_itx> 200 steps is ~1 turn right?
[16:01:38] <CaptHindsight> yeah, but it might step 327 every time of 645, not sure exactly
[16:01:44] <CaptHindsight> of/or
[16:02:17] <CaptHindsight> but, yeah most steppers are 200 steps/rev
[16:02:23] <Tom_itx> is there a comp to count pulses?
[16:03:06] <CaptHindsight> I have an optical sensor on the motor to act as a home or limit
[16:03:07] <Tom_itx> just figure out what 'distance' is the pulses you need and issue that as a subroutine
[16:03:20] <Tom_itx> on whatever axis you assign it to
[16:03:51] <CaptHindsight> never tried with a stepper, usually it's analog or real time IO
[16:03:52] <Tom_itx> you should be able to calculate that
[16:04:40] <Tom_itx> then just call the sub when you need it
[16:04:44] <CaptHindsight> I have to see how a non XYZABC etc stepper drops into the configs
[16:04:59] <Tom_itx> yeah, i'm not sure
[16:05:50] <Tom_itx> what about joint mode instead of axis?
[16:05:55] <Tom_itx> dunno what you're doing...
[16:06:12] <CaptHindsight> they use a stepper motor with a cam on the shaft to tilt a platform
[16:07:57] <CaptHindsight> so the cam just needs to turn the same amount of degrees every time in one direction, or change direction every time it moves and use the exact number of steps
[16:08:31] <Tom_itx> sub could do that if you can just use one of the normal axis
[16:09:03] <Tom_itx> it doesn't know what it's driving really
[16:09:06] <CaptHindsight> I can make it axis A
[16:09:28] <Tom_itx> that would probably be the least 'technical' way
[16:09:51] <Tom_itx> and it could sync with another axis if needed
[16:09:57] <CaptHindsight> as long as setting up the AXIS gui doesn't show it as a rotating axis
[16:12:43] <CaptHindsight> and it should be easy to edit the g-code to add this
[16:19:24] <CaptHindsight> thinking about it now, what if I wanted it to be visible in AXIS
[16:20:45] <XXCoder> im sure thats possible
[16:20:46] <CaptHindsight> how can you have a cam on one side of your X-axis table and hinge on the other and have AXIS display it's motion?
[16:21:00] <CaptHindsight> it's/its
[16:21:06] <XXCoder> plus you can use it in case you wanna add A B or C axis
[16:21:28] <CaptHindsight> it's not a mill or cutting machine
[16:21:36] <CaptHindsight> it's a putting machine
[16:21:45] <CaptHindsight> it puts vs cuts
[16:22:44] <XXCoder> ah
[16:25:02] <Tom_itx> you'd have to customize the way axis shows it i bet
[16:25:55] <CaptHindsight> I have all the time in the world as long as 1 hour is all that time
[16:26:21] <CaptHindsight> ready by 5
[16:32:34] <CaptHindsight> looks like a job for HAL
[16:40:37] <Deejay> gn8
[16:45:38] <CaptHindsight> http://linuxcnc.org/docs/html/hal/rtcomps.html#sec:stepgen I see how to setup stepgens
[16:47:04] <Tom_itx> ahh i see... you want it free AND you want it now!
[16:47:36] <malcom2073> call J.G.CNC! 800 cash cow!
[16:49:03] <Tom_itx> if it's due by 5, he might actually be working..
[16:50:51] <CaptHindsight> free! Who's been funding all the new RTAI development the past 3 years?
[16:51:27] <CaptHindsight> that's one of the catches with open source, you have to blow your own horn
[16:56:22] <Tom_itx> the custom Mcode is probably the best way to go since it needs to be portable
[16:57:11] <CaptHindsight> Mcode to hal stepgen with whatever number of steps = 1 position unit
[16:57:24] <Tom_itx> i was watching..
[16:57:45] <Tom_itx> i've never done a custom mcode though
[16:58:14] <CaptHindsight> it just seems like I'm missing something here, like there is a better way to do it
[16:58:30] <CaptHindsight> but I can' think of any
[16:58:38] <CaptHindsight> can'/can't
[16:58:38] <Tom_itx> me either
[16:58:53] <Tom_itx> ladder would work but i've not used it yet either
[16:59:04] <JT-Shop> CaptHindsight: you just need to move a stepper some number of step?
[16:59:08] <Tom_itx> yep
[16:59:17] <CaptHindsight> and it's not for an axis
[16:59:27] <CaptHindsight> and it has to drop into g-code
[16:59:41] <JT-Shop> http://gnipsel.com/linuxcnc/examples/winder.zip
[16:59:58] <JT-Shop> oh a M1xx then
[17:00:44] <CaptHindsight> I use M62 and M63 all the time to sync printheads and valves to motion
[17:03:03] <JT-Shop> I use M68 to set my plasma component
[17:03:51] <JT-Shop> you could use a M67 with a custom component I suppose
[17:06:18] <CaptHindsight> hmm maybe I spoke to soon about those tb6600 drivers....
[17:06:34] <CaptHindsight> the motors are as hot as hell after parking for an hour
[17:07:06] <Tom_itx> no idle shutdown like the good ones
[17:08:02] <CaptHindsight> yeah, they are ~80C
[17:08:08] <CaptHindsight> crap
[17:08:33] <Tom_itx> better find one with idle shutdown if they're gonna be sitting quite a while
[17:08:42] <CaptHindsight> I was starting to smell fresh hot insulation
[17:08:54] <Tom_itx> be handy at lunchtime..
[17:12:39] <CaptHindsight> looks like different drives or bigger heat sinks on the motors
[17:19:36] <MacGalempsy> how about a water cooling heat sink?
[17:21:28] <CaptHindsight> with heat pump and exchanger?
[17:21:44] <CaptHindsight> plus battery back up Peltier
[17:22:38] <MacGalempsy> I have been wondering about some of the custom PC CPU kits from ebay for steppers in this cabinet printer I have been working on
[17:23:13] <MacGalempsy> from what I recall from the reprap forum 80 is about the top temp for steppers
[17:24:18] <CaptHindsight> I lowered the max current from 5A to 0.6A and they are now 20C cooler
[17:24:45] <CaptHindsight> MacGalempsy: you just need better stepper drivers
[17:25:23] <MacGalempsy> probably. but too hot and they start missing steps.
[17:26:00] <CaptHindsight> thats where proper motor sizing and better drives come in
[17:26:43] <MacGalempsy> the cabinet printer has a heated chamber, so that is the limiter here.
[17:27:46] <CaptHindsight> the SLS printers hold the powders in the build area at up to 210C..
[17:28:18] <MacGalempsy> you have an sls?
[17:28:23] <CaptHindsight> you have to isolate the build platforms and wipers from the motors that actuate them
[17:29:00] <MacGalempsy> http://www.ebay.com/itm/ARCTIC-Freezer-Xtreme-Rev-2-CPU-Cooler-Intel-AMD-Twin-Tower-Heatsink-New-/281705656306?hash=item4196f72ff2:g:bYQAAOSwl8NVZ8S4
[17:29:02] <MacGalempsy> lol
[17:29:10] <MacGalempsy> this would keep them cool
[17:29:12] <CaptHindsight> I build all sorts of additive machines, most are hybrids that have more than one tech
[17:29:33] <MacGalempsy> can your sls do metal?
[17:29:40] <CaptHindsight> SLA + inkjet, or SLS with FDM
[17:30:07] <CaptHindsight> metals or polymers
[17:30:55] <CaptHindsight> the build areas/ovens also have to be gas tight so you can flood them with nitrogen or argon
[17:31:37] <CaptHindsight> even SLA needs an oxygen free environment
[17:31:44] <MacGalempsy> cool. I read up a little recently. You got any pics of one of your units?
[17:33:06] <CaptHindsight> https://imagebin.ca/v/2TZ69LKPSZ6P 5-axis inkjet for photopolymer deposition
[17:34:19] <MacGalempsy> all steppers on that thing?
[17:34:46] <CaptHindsight> https://imagebin.ca/v/2aq0JWfJZfXK 3-axis inkjet and micro-nozzle for DNA deposition
[17:34:59] <CaptHindsight> the 5 axis is all linear motors
[17:35:25] <CaptHindsight> ~$70K worth, holds <5um repeatability
[17:35:52] <CaptHindsight> also has a laser and microscope for inspection and spot curing
[17:36:07] <CaptHindsight> all automated with machine vision
[17:36:51] <MacGalempsy> no idea what machine vision is
[17:37:26] <CaptHindsight> https://en.wikipedia.org/wiki/Digital_image_processing
[17:38:00] <CaptHindsight> the machine looks at the materials and spots defects and aligns itself without a human user/operator
[17:39:10] <MacGalempsy> muy interestante
[17:39:23] <CaptHindsight> https://www.youtube.com/watch?v=8RbD4X8y65A Image Processing tutorial part 1: Basic object tracking
[17:39:49] <MacGalempsy> so you program them, too? or just build the hardware?
[17:40:03] <CaptHindsight> I try to avoid any coding
[17:40:36] <CaptHindsight> I'd rather belt sand my nipples then write code
[17:40:54] <MacGalempsy> which grit?
[17:40:57] <CaptHindsight> not that there's anything wrong with either
[17:50:02] <CaptHindsight> https://www.youtube.com/watch?v=TTnho9-i6dI Introduction to Machine Vision
[17:51:09] <malcom2073> We do a lot of machine vision stuff at work, it's pretty amazing what computers can do nowadays
[17:51:15] <malcom2073> Do a lot of stereo vision stuff
[17:52:29] <CaptHindsight> mostly single lens
[17:52:56] <Tecan> was wondering if anyone here would know what tubing with the rubber seam for 2 way flow would be called
[17:53:20] <Tecan> 2 rubber hoses attached
[17:53:21] <Tom_itx> what type of tubing?
[17:53:26] <CaptHindsight> malcom2073: we used to have to do it with dedicated boards that plugged into ISA bus
[17:53:38] <Tom_itx> check welding supplies
[17:53:41] <CaptHindsight> 8mhz bus with 25mhz DSP
[17:54:01] <Tecan> was thinking something smaller for that fuel line stuff
[17:54:02] <CaptHindsight> or array processor
[17:54:06] <malcom2073> Hehe yeah, we had our guys designing their own ASIC's for processing back in the day
[17:54:26] <malcom2073> Giant server boards that have 1% of the power of even a mediocre graphics card now
[18:50:59] <MacGalempsy> anyone have experience running the carousel component with a mesa card?
[18:55:43] <MacGalempsy> specifically the 7i77. I am trying to determine how to make a signal between the encoder and carousel
[18:58:00] <ljn> starting first install of linuxcnc
[19:05:29] <MacGalempsy> welcome to the club
[19:07:23] <ljn> thanks - no questions yet planning to follow the instructions for ubuntu 12.04
[19:11:15] <JT-Shop> ljn: you might want to think about LinuxMint 17.3...
[19:11:59] <JT-Shop> Roguish: are you around?
[19:13:03] <ljn> OK I'll download Mint instead was just about to burn the ubuntu 12.04 DVD
[19:14:30] <JT-Shop> http://gnipsel.com/files/linuxmint/mint17.3.txt
[19:14:44] <JT-Shop> how I installed on linuxmint
[19:15:26] <ljn> thanks!
[19:15:36] <JT-Shop> np
[19:16:04] <MacGalempsy> not being a long time linuxuser, what is the reason someone would want to use linuxmint as opposed to what comes with the standard install of linuxcnc?
[19:17:09] <JT-Shop> well IMHO debian wheezy just makes life as hard as they can... jessie is better but LinuxMint is better again IMHO
[19:17:42] <JT-Shop> I just want it to work not have to play guessing games and not be able to copy files from my desktop to the machine etc
[19:18:18] <MacGalempsy> ah, I think i get it
[19:19:36] <CaptHindsight> stepper motors are now at 32C and 42C
[19:38:31] <CaptHindsight> can you define M-codes over M199? Is there some hard limit in Linuxcnc?
[19:45:04] <Frank_15> helloooo
[19:50:30] <andypugh> CaptHindsight: Remap lets you redefine any M-code that isn’t used, and many that are.
[19:53:38] <dioz> anyone here weld galv iron sheet metal before?
[19:53:56] <andypugh> Yes
[19:54:09] <malcom2073> dioz: Loetmichel does
[19:54:16] <dioz> heh
[19:54:23] <malcom2073> ;)
[19:54:42] <dioz> MacGalempsy: typically the choice of distro is personal preference.
[19:54:45] <Loetmichel> malcom2073: i do what?
[19:54:58] <dioz> i mean you could argue that fedora is better than debian is better than arch is better than LFS
[19:55:04] <dioz> but in the end it all comes down to package preference
[19:55:17] <andypugh> Makes a white sooty mess. Can make you ill, apparently, but hasn’t ever made me ill.
[19:55:33] <dioz> apt vs pacman vs synaptics vs etc
[19:55:53] <dioz> andypugh: can you use acid to clean the galv off before welding and will that fix it like with soldering?
[19:56:02] <dioz> "fix it" the spattering and burning
[19:56:16] <Loetmichel> ah, that zinced sheet steel again?
[19:57:00] <dioz> i'm personally a OBSD guy though
[19:57:03] <dioz> OpenBSD eve3.emopart.com 6.0 GENERIC#2107 amd64
[19:57:14] <malcom2073> Loetmichel: Go away, I was poking a bees nest, sorry :)
[19:57:25] <malcom2073> I like apt myself
[19:57:37] <dioz> yah if i wasn't in bsd i'd be using debian tbh
[19:58:06] <Loetmichel> malcom2073: hu?
[19:58:14] <malcom2073> Loetmichel: I'm trolling.
[19:58:17] <andypugh> dioz: You can grind it off. You probabably should grind it off the weld area itself, who knows what it will do to the steel compositon?
[19:58:18] <Loetmichel> ah!
[19:58:19] <malcom2073> Loetmichel: Ignore the conversion
[19:58:59] <Loetmichel> malcom2073: i only ready yours and andypughs suggestions ;)
[19:59:08] <Loetmichel> anyways
[19:59:24] <dioz> andypugh: when i went to trade school for sheet metal one of the segments was soldering
[19:59:39] <dioz> we'd use dilute muriatic acid to clean the galv before soldering or the solder wouldn't stick
[19:59:53] <dioz> the instructor never mentioned the possibilty of wrecking the iron
[20:00:01] <dioz> i could see the concern though
[20:00:08] <dioz> just cause it wasn't mentioned doesn't mean it might not happen
[20:00:29] <dioz> we were given like a day on the welders and plasma cutters
[20:00:33] <andypugh> I have often ignored it, welded through it, and got away with it. But that’s me being lazy and careless. If you choose to do the same then be aware that you are being lazy and careless. And if you do feel ill the next day then realise that you are susceptible and don’t do it again.
[20:00:35] <dioz> more-so tested on the theory of the items
[20:01:09] <dioz> i just wanna talk to someone with first hand experience
[20:01:30] <andypugh> Solder does not get hot enough to combine the zinc into the weld pool, and solder is far weaker than steel anyway.
[20:01:34] <dioz> my boss (sheet metal journeyman) has only gone mig and he says "it's really really hard to weld thin sheet metal"
[20:01:57] <dioz> he said "it isn't impossible it's just hard"
[20:02:16] <dioz> then we talked about HF vs scratch start and tig vs. mig
[20:02:18] <andypugh> How thin?
[20:02:29] <dioz> 14-26 gauge galv iron
[20:02:45] <dioz> i got a pile of 20 gauge in my garage
[20:02:59] <dioz> cause we were gonna throw it out but i wanna buy a rig and get good at it
[20:03:07] <dioz> so i thought i'd use it for practice
[20:03:13] <dioz> a huge fucking pile
[20:03:31] <MacGalempsy> then you should be able to get goooooood at it
[20:03:46] <dioz> i wanna be pro at it infact
[20:03:46] <andypugh> That is pretty thin. You will learn a lot.
[20:04:16] <dioz> i also broke 3 pairs of wiss snips in a month cutting 14 gauge angle iron this week
[20:04:25] <dioz> thank god wiss has warranty ;]
[20:04:35] <dioz> :s/week//
[20:04:53] <dioz> i was talking to my gf and typed "this week" as i said it to her
[20:05:11] <andypugh> How’s your eyesight? You will want a very small arc-length and a small tungsten. You are going to need to be up close and watching small things.
[20:05:29] <dioz> i'm 32 years old and don't need glasses if that means anything
[20:06:06] <andypugh> If you can focus at 12” that will help.
[20:06:36] <dioz> today i was on site and i parked my car on the road out front the hotel we're hanging duct in and it's so windy that the steel fence blew over and landed on my car
[20:06:51] <dioz> i have a nice orange stripe down the length of my car and across my bumper now
[20:07:04] <andypugh> (Seeing what I am doing is currently my limit, I am serioulsy considering welding glasses, even though I don’t need reading glasses)
[20:07:04] <MacGalempsy> this is what my goal is to accomplish through linux cnc https://www.youtube.com/watch?v=_qhZFGOKkEk
[20:07:27] <dioz> andypugh: i notice a lot of the welding helmets have the ability to attach magnifying glasses to them
[20:07:49] <andypugh> Indeed, I just ordered some :-)
[20:08:10] <dioz> i think we're gonna have a tornado here tbh
[20:08:17] <dioz> my house is making horrible noises
[20:08:19] <dioz> cause of the wind
[20:08:42] <andypugh> MacGalempsy: Do you know if that is LinuxCNC?
[20:09:03] <BeachBumPete> MacGalempsy how is yours coming along....or is that yours?
[20:09:19] <MacGalempsy> i do not know. it is a random youtube video of how my machine operates
[20:09:42] <andypugh> I see nothing there that LinuxCNC can’t do
[20:09:48] <MacGalempsy> BeachBumPete: well, at the moment it is waiting for a new pc. the 3rd one went out
[20:10:00] <BeachBumPete> wow really?
[20:10:04] <MacGalempsy> this time im getting a new rig
[20:10:08] <MacGalempsy> no more used stuff
[20:10:12] <BeachBumPete> ah
[20:10:35] <BeachBumPete> I always try to build a new PC into my builds it is not all that expensive anymore to do so...
[20:10:51] <andypugh> MacGalempsy: Look at the sim/axis/vismach/VMC-toolchange config.
[20:10:53] <MacGalempsy> but once its back and going, I have it homing and the vfd is working good
[20:11:07] <BeachBumPete> nice
[20:11:27] <MacGalempsy> i wrote up a detailed description and a plan of attack in the forum post
[20:11:29] <andypugh> That uses the “carousel” HAL component with a G-code subroutine to handle the axis and moe sequences.
[20:11:42] <MacGalempsy> but have been reading all day about the different components
[20:11:46] <andypugh> MacGalempsy: Yes, I just saw it
[20:11:57] <BeachBumPete> I can't wait to try that new component myself
[20:12:03] <dioz> are there any other channels on freenode about construction or metal fabrication or things of that sort? plumbing? (heh)
[20:12:23] <dioz> you know how a plumber gets their ticket 'eh?
[20:12:35] <dioz> in one hand you put a turd in the other you put a chocolate bar and if they don't eat the turd they get the ticket!
[20:13:26] <MacGalempsy> I think it will need a way to send variable speed to the dc carousel motor, so it can be PID tuned. The encoder is reading through the 7i77
[20:13:27] <andypugh> MacGalempsy: You may not need CL if you are not already familiar with it. The carousel comp and a remapped G-code sub might work for you, especially if you are more familiar with G-code than ladder
[20:13:50] <dioz> fuckin sparkie (electrician) came on site the other day and was running cat6 cable. i said "what's the difference between cat5e and cat6?" he said "cat6 has 1 more pair"
[20:14:02] <MacGalempsy> i did pass the gcode programming night class
[20:14:04] <dioz> i lol'd but said "oh yah" like i was accepting his answer
[20:14:40] <BeachBumPete> I need to find me a good CHEAP electrician ;)
[20:14:55] <MacGalempsy> how cheap?
[20:14:58] <andypugh> MacGalempsy: A lot of carousels just move at a constant speed until the index and stop. No PID
[20:15:06] <dioz> there's three things. cheap, fast, good... but you can only have two of them
[20:15:07] <BeachBumPete> good and cheap
[20:15:12] <dioz> if it's cheap and fast it's gonna be shitty
[20:15:18] <dioz> if it's good and fast it's expensive
[20:15:18] <MacGalempsy> the problem is there is no indexing
[20:15:29] <dioz> if it's good and cheap it's gonna take forever
[20:15:29] <andypugh> I am good and cheap but not an electrician :-)
[20:15:53] <MacGalempsy> can I fake an indexing signal using an encoder position?
[20:16:04] <BeachBumPete> my new house has a 200 amp service on it but the panel is an older one and there is no more room in there because of all the smaller 110 v breakers.... I may need to remove it and install a new longer panel with more capacity
[20:16:21] <dioz> sounds like a DIY
[20:16:23] <dioz> check youtube
[20:16:26] <andypugh> MacGalempsy: The carousel is purely encoder?
[20:16:26] <dioz> i'm sure you'll figure it out
[20:16:29] <dioz> if you don't die
[20:16:32] <dioz> ;]
[20:16:40] <Loetmichel> andypugh: electrics/electronics are simple
[20:16:42] <BeachBumPete> gee thanks man
[20:16:55] <MacGalempsy> yep.
[20:16:58] <Loetmichel> if you stay below a few 100MHz its all logic ;)
[20:17:11] <Loetmichel> above that it gets slightly voodoo
[20:17:28] <andypugh> Loetmichel: I know, I do lots of both. I just don’t let the authorities find out, as I am unqualified.
[20:17:32] <BeachBumPete> I am sure I could probably replace the panel myself but there are legalities involved or at least permits
[20:17:36] <Loetmichel> hrhr
[20:17:45] <dioz> hooooly fuck there's a tornado
[20:17:47] <dioz> brb
[20:17:57] <dioz> tv just turned red and made a horrible noise
[20:17:58] <BeachBumPete> oh hell
[20:18:16] <dioz> i gotta make sure i have enough beer
[20:18:18] <BeachBumPete> that is a sign of a tornado?
[20:18:47] <dioz> "Conditions are favourable for the development of severe thunderstorms that may be capable of producing strong wind gusts, large hail and heavy rain ..."
[20:18:48] <Loetmichel> BeachBumPete: in germany you not only have to be a certfied "elektromeister", you ALSO have to be acreedited to the utility that is suipplying the house in question
[20:18:55] <Wolf_> BeachBumPete: could look in to double breakers (2x 110 in one breaker slot)
[20:18:57] <andypugh> MacGalempsy: In that case you can (in theory) simply set up the carousel as an A-axis, add it to the homing sequence, and move to a calculated A-position in the G-code subroutine
[20:19:03] <Loetmichel> ... theoretically ;)
[20:19:18] <dioz> i like that
[20:19:22] <dioz> "elektromeister"
[20:19:34] <BeachBumPete> Wolf I have been told to either replace it or get an aux panel along side it...
[20:19:39] <dioz> someone ask Loetmichel what they call tin bangers in germany considering the punk has me on ignore
[20:20:05] <MacGalempsy> so would you recommend I change out the relay for a variable speed motor control?
[20:20:20] <Wolf_> sub panel works too
[20:20:25] <andypugh> Loetmichel: In the UK you just need to be qualified. (oddly, because of older laws, for gas the legal requirment is “Competent” not “qualified” )
[20:20:40] <MacGalempsy> +/-10V control so it can be PID tuned?
[20:20:46] <ljn> BeachBumPete: yes why not add a sub panel. I had a similar problem added 100A panel
[20:21:05] <dioz> to add a sub panel do you need more wires run from the service?
[20:21:15] <dioz> does your carrier need to get involved?
[20:21:17] <andypugh> MacGalempsy: If it currently works with just a relay then it can continue to do so.
[20:21:35] <dioz> i would imagine you do
[20:21:49] <ljn> no you can shut off the main breaker and install the panel
[20:21:50] <Loetmichel> andypugh: the german utilties cant legally forbid you do do work behind the meter... but they can theoretically refuse to supply the house until one of THEIR certified electicans has overlooked the whole installation.
[20:21:57] <BeachBumPete> ljn that would be great I am not sure how it is setup but it would be off the mains coming in I think 100 amp would work for me
[20:22:19] <Loetmichel> but on the other hand: if they dont know it....
[20:22:26] <dioz> just cut in before the meter
[20:22:27] <MacGalempsy> andypugh: the relay is my way of getting it to work, it is not necessarily the original way.
[20:22:28] <andypugh> Loetmichel: That’s a lot more flexible than the rules here. Which is unusual :-)
[20:23:09] <andypugh> MacGalempsy: It’s late here (very late) but I will try to get back to your forum post.
[20:23:46] <andypugh> I have a feeling that “carousel” won’t help, but need to think further
[20:24:37] <MacGalempsy> much appreciated as always
[20:24:43] <andypugh> You might get away with scaling the eoncoder right and using wcomp to operate the relay.
[20:24:59] <Loetmichel> andypugh: i once did the whole thing including the main panel with the meter space for my cousin. the meter guy came, looked into the panel: "that did no pro, am i right?"
[20:25:33] <Loetmichel> my cousin admited that i did that... "thougt so. WAY to clean for a pro. there was someone with dedication and time at work" ;)
[20:25:39] <zeeshan> lots of cnc talk in here :)
[20:25:40] <zeeshan> nice to see
[20:26:12] <BeachBumPete> I hate to take the old panel out but I would not mind seeing a new one in there with more space
[20:27:20] <Loetmichel> BeachBumPete: when i moved in here in that rented flat there were 3 fuses. "stove;washing machine;rest of the stuff"
[20:27:24] <BeachBumPete> My friend who lives here said he knew a guy who does side work that might do it for me but I gotta get with him to see what he might charge.
[20:27:34] <BeachBumPete> jeez
[20:27:54] <BeachBumPete> are they actually fuses or breakers?
[20:28:03] <Loetmichel> ... now there is a new panel and 1000ft of new wire in the walls: http://www.cyrom.org/palbum/main.php?g2_itemId=3209&g2_imageViewsIndex=1
[20:28:11] <zeeshan> pete got a new house?
[20:28:12] <zeeshan> :D
[20:28:17] <MacGalempsy> BeachBumPete: some of the older panels are impossible to find replacement breakers for. do you know how old it is?
[20:28:28] <Loetmichel> BeachBumPete: screw-in fuses
[20:28:48] <BeachBumPete> the house was built in the 80's
[20:28:56] <BeachBumPete> zeeshan yeah
[20:29:03] <zeeshan> congrads man :D
[20:29:06] <MacGalempsy> that should be new enough
[20:29:08] <zeeshan> you'll be back in the cnc action!!!!!!!!!
[20:29:08] <zeeshan> :D
[20:29:23] <BeachBumPete> thank you its great but it is gonna cost a good bit more so that is not so great LOL
[20:29:28] <zeeshan> youre handy
[20:29:31] <MacGalempsy> you can take a redneck out of Tenessee, but you cant take Tenessee out of a redneck
[20:29:35] <zeeshan> you can save money by diy
[20:29:36] <zeeshan> :D
[20:29:51] <BeachBumPete> MacGalempsy LOL I was NEVER a redneck
[20:30:02] <zeeshan> arent you from cali
[20:30:03] <zeeshan> lol
[20:30:07] <zeeshan> originally
[20:30:09] <BeachBumPete> we moved to TN because we liked it
[20:30:30] <MacGalempsy> lol. it got old aye?
[20:30:37] <BeachBumPete> I was born in Upstate New York and grew up in South Florida my wife is from Cali and I spent a lot of time there
[20:30:39] <Loetmichel> BeachBumPete: didnt look so pretty when i was at work tho: http://www.cyrom.org/palbum/main.php?g2_itemId=3200&g2_imageViewsIndex=1
[20:31:16] <BeachBumPete> MacGalempsy Honestly I lived there for like 16 years and kinda missed Florida. Most of my family is here now
[20:31:40] <BeachBumPete> Loetmichel WOW
[20:31:50] <MacGalempsy> looks like medusa's hair!
[20:32:04] <MacGalempsy> dont look at the panel, it will turn you to stone
[20:32:37] <zeeshan> wtf
[20:32:37] <zeeshan> lol
[20:32:46] <renesis> eh
[20:32:54] <renesis> there are a fuckton of rednecks in cali
[20:33:00] <renesis> maybe a million of them
[20:33:22] <BeachBumPete> I am sure I can take care of replacing the panel safely if I can turn off the power coming in but I think to do that you must remove the meter head and they will know about it then
[20:33:35] <renesis> desert rednecks, northern and southern california hillbillies, various white trash
[20:33:46] <MacGalempsy> just consider if there are any permit regulations
[20:33:59] <BeachBumPete> I am sure there probably are...
[20:34:11] <MacGalempsy> here in BFE arkansas, they aren't necessary in the county areas
[20:34:25] <BeachBumPete> this city LOVES permits and regulations... my best friend here is an AC guy and he is constantly bitching about the city and their BS
[20:34:31] <Loetmichel> BeachBumPete/ MacGalempsy: did the flat in sections. SO i had to temporarily supply the rooms with "flying wire"
[20:34:48] <Loetmichel> Eventually all of them were sorted, paralleled and put into the wall
[20:35:05] <Loetmichel> afterwards it looked like this: http://www.cyrom.org/palbum/main.php?g2_itemId=3203&g2_imageViewsIndex=1
[20:35:22] <Loetmichel> i may remind you that we usually have brick walls here
[20:35:29] <BeachBumPete> my thinking is that since the original panel is short=ish I should be able to add a new panel and just put the existing stuff at the top
[20:35:35] <MacGalempsy> The last house I had a new box installed. I think the box with fuses was like $300 and the labor was around $800
[20:35:54] <BeachBumPete> that is not exactly unreasonable I think
[20:35:55] <MacGalempsy> maybe total was 800
[20:36:17] <BeachBumPete> I was thinking like you said 3 for the box and fuses and another 5 for labor plus permits...
[20:36:46] <MacGalempsy> Yeah permits...
[20:37:03] <BeachBumPete> electrical permits here are like 125 or so
[20:37:15] <MacGalempsy> are you in a neighborhood?
[20:37:21] <BeachBumPete> sure
[20:37:36] <MacGalempsy> yeah, they dont want you burning down the neighborhood
[20:37:45] <MacGalempsy> brb
[20:37:48] <BeachBumPete> neither do I
[20:39:06] <Wolf_> biggest pain w/ new panel is most of the time you need to have the meter pulled to swap in the new one
[20:40:13] <BeachBumPete> Wolf_ that is what I think too. I would do it myself if that was not part of the game... I was thinking of adding a sub panel but not sure how to splice it into the older box
[20:40:46] <ljn> no splice but you need to find space for a large breaker
[20:41:02] <Wolf_> pull 2 breakers and the wires they feed, put in a 100A 220v to feed the sub
[20:41:14] <Wolf_> my main panel is feeding 2 sub panels here right now
[20:41:54] <BeachBumPete> Wolf is it that simple? what is your max amp on the main? Got any pics? DId you do it yourself?
[20:42:41] <MacGalempsy> I recall the breaker being an issue
[20:42:56] <MacGalempsy> but, there was like small reconnection fee
[20:43:02] <Wolf_> yeah, I diy all of it, pics wouldnt show much, just 100A breaker with #4 alum wire hooked to it
[20:43:09] <MacGalempsy> that may be one way they make sure you have the permits
[20:43:53] <Wolf_> here the electric co won’t pull the meter unless there is a permit and a licensed electrician doing the work
[20:44:22] <BeachBumPete> I am sure it is the same here
[20:44:46] <BeachBumPete> I would prefer to NOT drop a grand for it but if it has to be it has to be
[20:45:19] <Wolf_> main panel is 250A I think, its now empty except RV plug, service outlet under the panel and 2 sub panel hookups, but my main panel is on the back of my house outside right now also…
[20:46:54] <Tom_itx> BeachBumPete, you need a pretty good license to clip that little meter tag to remove the meter :D
[20:47:06] <BeachBumPete> one good thing is the box is right in the garage where the machines/welder will be
[20:47:16] <Tom_itx> and yes that needs done to replace the pannel
[20:47:32] <BeachBumPete> Tom_itx thanks I am aware
[20:47:35] <MacGalempsy> unless you can stage a power outage
[20:47:44] <Tom_itx> early 80
[20:47:47] <Tom_itx> s?
[20:47:54] <Wolf_> sometimes you can get the tags apart :D
[20:48:01] <Tom_itx> make sure there isn't any aluminum in it
[20:48:03] <Wolf_> not that I have ever done that…
[20:48:33] <BeachBumPete> we have the digital remote meters here
[20:48:37] <Wolf_> just make sure the main breaker is off before setting the meter back in place
[20:48:46] <ljn> ran into a make error during sudo apt-get install linux-headers ... I need to step out but maybe someone can help me later?
[20:49:04] <BeachBumPete> I don't see me being able to do that even if I wanted to there are houses all around me
[20:49:05] <ljn> What would be the best way to share an error message?
[20:49:42] <Tom_itx> they'd get pretty upset to see the tag clipped even if they found nothing else
[20:50:07] <BeachBumPete> to be clear I have no intentions of breaking the law let alone any tags
[20:50:17] <Tom_itx> i know
[20:50:33] <BeachBumPete> I might try to do my own sub panel inside but if I have to replace the whole panel I would just pay the man
[20:50:40] <Tom_itx> i had a new pannel put in years ago and the above prices seem inline with it
[20:51:00] <BeachBumPete> what about 800?
[20:51:01] <Tom_itx> do you just want more breaker room?
[20:51:11] <Tom_itx> 1k ish yes
[20:51:25] <Wolf_> my problem is I need the incoming service line moved from the back of my house to the front, they really won’t let you DIY that lmao
[20:51:35] <Tom_itx> i added a pannel to my garage but it's off a large breaker in the main pannel
[20:51:52] <BeachBumPete> well yeah basically I want to add enough to wire up basically the 60 amp for the VMC, a 50 amp for the lathe and another 30 or 50 for the Tig...
[20:52:13] <Tom_itx> you may need 400A service for that
[20:52:17] <Tom_itx> instead of 200
[20:52:28] <Wolf_> only if you are going to run it all at once lol
[20:52:37] <Tom_itx> codes come into play
[20:53:13] <Wolf_> well, yeah if you have the electrical put in all the outlets
[20:53:24] <Tom_itx> is the main service breaker 100 or 200A?
[20:53:28] <Wolf_> electrician even
[20:53:49] <BeachBumPete> the main is 200 but yeah not usually running more than two at once...
[20:54:09] <Tom_itx> you could just add a large breaker to a subpannel like i did
[20:54:18] <Tom_itx> just don't exceed it
[20:54:26] <BeachBumPete> did it daily in Tennessee with the same max amp panel with no issues
[20:54:36] <BeachBumPete> did you DIY that or pay the man?
[20:54:43] <Tom_itx> what do you think?
[20:54:57] <BeachBumPete> couldn't guess ;)
[20:55:02] <Wolf_> lol
[20:55:11] <Tom_itx> when i did my basement though, i had someone replace the main pannel for me
[20:55:19] <Tom_itx> i did all the rest
[20:55:22] <BeachBumPete> so you put say a 100 amp breaker in and then came off that?
[20:55:49] <Tom_itx> i went with either 50 or 60 to the garage but i don't run anything too big out there
[20:56:03] <Tom_itx> just make sure the wire you use is rated right
[20:56:29] <BeachBumPete> my plan is to tell them that I want to run my old tig welder which is like 50 amp max out there they don't need to know anymore than that
[20:56:45] <Wolf_> I did a 100A to my garage, 175 feet from the house, have had the air compressor, air drier, plasma and miller 210 all running at the same time
[20:56:50] <Tom_itx> put a 60 on the main and run it to the pannel
[20:56:57] <MacGalempsy> can you get 3 phase to the house?
[20:57:03] <Tom_itx> i doubt it
[20:57:16] <BeachBumPete> I have some really heavy gauge wire for the VMC I don't remember the gauge offhand
[20:57:19] <Tom_itx> not without a big hassle with the electric company
[20:57:24] <BeachBumPete> don't need or want 3 phase
[20:57:33] <Tom_itx> my bud did it once
[20:57:51] <Tom_itx> it took them a good couple months to get the transformer and pole planted
[20:58:16] <Wolf_> I think the rate/billing is totally different for 3 phase here
[20:58:17] <Tom_itx> he had to demonstrate he would use the service if it was provided
[20:58:53] <BeachBumPete> all my machines are either single phase or have been converted to run on it
[20:59:18] <Tom_itx> BeachBumPete figure the most you would need at any one time and figure that for your breaker
[20:59:30] <Tom_itx> if you put in a 100A breaker the wire would be fairly large
[20:59:35] <Wolf_> ^
[20:59:43] <Wolf_> no need to over kill it
[20:59:51] <Tom_itx> so i'd go with 60ish or so
[20:59:53] <BeachBumPete> I like overkill
[21:00:04] <Tom_itx> then pay the price
[21:00:05] <BeachBumPete> the VMC alone need 60
[21:01:18] <Wolf_> I’m planning on replacing my shop, I’ll probably have new service run out to it so I don’t need to deal with sub panel setup
[21:01:28] <BeachBumPete> if I can finaggle a spare 30 amp from the old panel for my compressor and other 220 small HP stuff I can run just the 100 amp for the CNC's and not run them at the same time. Have never done that before anyway LOL
[21:02:23] <Tom_itx> http://www.cerrowire.com/ampacity-charts
[21:02:34] <BeachBumPete> not really sure how much power the CNC lathe will need but the spindle will be 7.5hp
[21:02:57] <MacGalempsy> zeeshan: its been a while. how is the machine shop coming along?
[21:03:12] <Tom_itx> looks like you would need 3 ga min
[21:03:36] <Tom_itx> iirc i used 6 on mine but i'm not positive
[21:04:28] <BeachBumPete> it is doable but will probably cost me a small fortune unfortunately..
[21:05:29] <Tom_itx> i'm not sure of the wire labelling either, not sure what jacket etc you need
[21:06:14] <BeachBumPete> Well since I work early I am off ta bed. Thanks guys and have a good night.
[21:06:42] <Tom_itx> probably about a buck a foot per conductor
[21:08:15] <Wolf_> whats funny, underground house feeder for multiple houses is 2/0 alum lol
[21:10:24] <Tom_itx> that's because aluminum is cheaper
[21:10:33] <Tom_itx> requires a larger gage though
[21:10:52] <Wolf_> that chart says 150A max for 2/0
[21:11:18] <Wolf_> over head feeder to my house is #2 alum I think
[21:12:28] <Wolf_> I use to work for a utility service contractor finding underground faults and doing new service installs
[21:12:33] <Tom_itx> http://www.powerstream.com/Wire_Size.htm
[21:12:37] <Tom_itx> calc at the bottom
[21:13:01] <Tom_itx> i dunno what the acceptable v-drop is
[21:15:15] <Wolf_> 11v drop on the stuff in my garage according to the calc on there
[21:15:35] <Wolf_> thats at full 100A draw
[21:44:22] <MacGalempsy> good night everyone!
[22:05:13] <ljn> installed linux mint and rtai kernel. With the default kernel the resolution is normal 1680x1050 for my monitor. Selecting the rtai kernel the res drops to 640x480
[22:05:59] <ljn> There is a message after selecting the rtai kernel "Running in software rendering mode"
[22:54:38] <ljn> editing the grub option seems to fix the resolution problem (removed gfxmode $linux_gfx_mode)
