[00:01:19] <skunkworks> http://imagebin.ca/img/tfMY4KeF.jpg
[00:15:23] <eric_unterhause1> I need one of those with 3 more walls, siding and a roof
[00:16:14] <archivist> skunkworks, moooore shed space?
[00:16:42] <skunkworks> shop away from the shop
[00:17:26] <skunkworks> 2.7 more wall
[00:17:30] <skunkworks> walls
[00:45:12] <eric_unterhause1> skunkworks: do you know how much that is going to cost?
[00:51:23] <skunkworks> eric_unterhause1: I don't know off the top of my head sans concrete - pretty close to 10k
[00:51:42] <eric_unterhause1> how much was the concrete?
[00:51:48] <crice> eric_unterhause1: I had them build something like that when I was having my house built in texas.
[00:52:03] <skunkworks> I would have to look
[00:52:18] <skunkworks> (that was 1.5 years ago
[00:52:22] <eric_unterhause1> so little you don't remember? I'm going for that deal
[00:52:59] <crice> It is 3 cars wide and 2 deep. About 1200 sq ft. It cost 20K including the rough in for a bathroom.
[00:53:18] <skunkworks> I am doing this myself
[00:54:13] <eric_unterhause1> did you pour the concrete yourself? you got skills
[00:54:22] <skunkworks> this is 26' X 48'
[00:54:41] <skunkworks> actually - I had the concrete done. I am so done with concrete work.
[00:54:53] <skunkworks> it needed footing and frost wall.
[00:55:10] <crice> I am doing the inside, insulation, sheetrock, ac, etc. myself. but had to let them do the outside. HOA Requirement.
[00:56:17] <skunkworks> where?
[00:56:43] <eric_unterhause1> HOAs are as close to an un-American organization as you can legally get in the U.S.
[00:56:47] <crice> Near Houston, Tx
[00:57:01] <cradek> skunkworks: is the little house that's 75% of the shop size your house?
[00:57:04] <skunkworks> yeck. Here all you need is a building permit.
[00:57:30] <eric_unterhause1> there are some areas here where even the building permit must not be required
[00:57:31] <skunkworks> cradek: yes - direcly behind the garage. (river on both sides)
[00:57:32] <cradek> here, building permit plus full plans stamped by an engineer
[00:57:37] <crice> HOAs are everywhere here. It is hard to find a place without them unless you buy a ranch.
[00:57:47] <skunkworks> yeck
[00:58:18] <cradek> (and we're not even in the city)
[00:59:17] <skunkworks> electrical is a 'don't ask don't tell'
[00:59:30] <cradek> heh, that gets inspected here.
[00:59:55] <skunkworks> In a house it does.. but I don't really know about a garage.
[01:00:14] <cradek> so have an electrician put in one light bulb and a switch that turns it on...
[01:00:41] <jmkasunich> with a 20 breaker panel "just in case"
[01:00:43] <cradek> maybe after the inspection is done, you'll even be lucky and find wiring behind the drywall.
[01:01:29] <skunkworks> The house will have a smaller box than the garage. I am thinking about backfeeding the house from the garage.
[01:01:29] <eric_unterhause1> breakers just seem to show up in my breaker box, dunno how that happens
[01:02:25] <skunkworks> the power pole is right at the corner of the garage. I could have them hook the feed into the garage instead.
[01:02:53] <eric_unterhause1> joggers do not mess with this on the bike path: http://fixedgeargallery.com/2008/sept/2/moabiker11_aim.htm
[01:04:01] <crice> That is the way mine is set up. Everything enters the detached garage panels, then on to the house.
[01:05:31] <skunkworks> cradek: http://www.electronicsam.com/images/house/newhehhouse.JPG
[01:33:32] <roh> hm.. are all houses built there this way?
[01:33:45] <cradek> skunkworks: is there heating in the floor of the shop?
[01:35:13] <skunkworks> yes - that is the plan
[01:35:23] <cradek> neat.
[01:35:38] <skunkworks> this is a old old house. It was moved a block and put on a new poured basement.
[01:37:15] <skunkworks> How do you like your new shop?
[01:39:42] <ds3> is there 240 3PH?
[01:41:27] <skunkworks> heh - no. not at this location. I don't know how close 3 phase is.
[01:41:52] <skunkworks> We are 2 blocks up from mainstreet. so I would think it is close.
[01:43:09] <skunkworks> (small town)
[01:43:21] <ds3> hmm
[01:45:23] <ds3> more importantly, are all the machines operational?
[01:46:10] <skunkworks> garage isn't done yet... So no.
[02:44:14] <roh> whohoo
[02:45:01] <roh> * roh has the mill doing things the way he wants, slowly.. toolchain now: qcad -> camExpert (qcad-payware) -> .nc into emc2
[07:13:40] <voxadam> I just noticed that EMC2 supports screw comp. I'm impressed.
[08:43:35] <tomp> tomp is now known as tomp3
[09:42:47] <tomp3> http://pastebin.ca/1402699
[09:43:00] <tomp3> an idea of how to visualize a hal file (maybe)
[09:43:16] <tomp3> also a demo
[09:44:12] <tomp3> for years i looked at ways to do 'netlists' of hal files
[10:06:30] <tomp3> hmm, i think i went thru dot before.. no bidirectional connections when directional exist
[13:14:28] <EatPotato> I want to submit two minor mistakes
[13:15:34] <EatPotato> (1) /usr/share/doc/emc2/ directory do not contains the gcode_main.html file with full description of the G-code used in the EMC2 program
[13:16:54] <EatPotato> (2) File `emc2_2.3.0_i386.deb' was too lage to download. It's too big. Be it 10-12 mb in size with additional emc2-doc_2.3.0_i386.deb, everything would be OK
[13:18:08] <EatPotato> Also, libpango 1.1 must be updated to libpango 1.20 if you don't want to update whole Ubuntu 8.04
[13:18:26] <EatPotato> Question:
[13:18:48] <EatPotato> Will same packets run on 64-bit platform?
[13:18:58] <eric_unterhause1> no
[13:19:03] <EatPotato> why?
[13:19:23] <EatPotato> will the script download other packages?
[13:19:33] <eric_unterhause1> there is no 64 bit emc
[13:19:41] <eric_unterhause1> you might be able to build it
[13:19:46] <EatPotato> :(
[13:19:51] <EatPotato> OK
[13:19:54] <eric_unterhause1> dual boot
[13:20:11] <EatPotato> So, I need a 32-bit desktop with PCI slot to use EMC2?
[13:20:37] <eric_unterhause1> no, it runs fine on 64 bit
[13:20:52] <eric_unterhause1> but 64 bit processors will run a 32bit operating system
[13:21:24] <eric_unterhause1> if you have more than 4 gig of memory, you will not be able to use it
[13:21:31] <EatPotato> How can I install 32-bit Ubuntu 8.04 onto 64-bit desktop PC?
[13:21:39] <eric_unterhause1> it will install
[13:21:43] <EatPotato> OK
[13:22:05] <eric_unterhause1> this computer is 64 bit, it runs the 32bit ubuntu just fine
[13:22:18] <EatPotato> Oh, OK
[13:22:22] <eric_unterhause1> also runs 32bit windows
[13:22:54] <EatPotato> And minimum RAM? I thought standard Ubuntu 8.04 need 512-768 Mb of RAM
[13:22:54] <eric_unterhause1> so I have 3 boot options, emc, 64bit ubuntu, 32bit windows xp
[13:23:09] <eric_unterhause1> don't know about that
[13:23:24] <eric_unterhause1> to boot a live cd, that may be the case
[13:23:30] <EatPotato> I can organize partitions to use several different OSs
[13:24:03] <micges> for livecd 8.04 need 512 or more
[13:24:09] <EatPotato> eric_unterhause1: no, it's relatively easy to buy a used PC for another 100 USD just for EMC2
[13:24:18] <eric_unterhause1> that too
[13:24:28] <archivist> * archivist uses free cast offs
[13:24:32] <eric_unterhause1> memory might be expensive
[13:24:35] <EatPotato> It's OK, RAM is easy de- and attachable
[13:30:46] <EatPotato> ´╗┐Is it a common practice, that you are given a DXF file and you see you need about an hour or so to arrange diameter compensation and layers and so on? Is it an operator's task?
[13:45:15] <cnc_engineer> Hi everyone!
[13:45:21] <EatPotato> Hi
[13:48:09] <cnc_engineer> we are experiencing very low feedrate on arc type machining, can anayone guids me why... I am generating g-codes using cad program(dell cam)
[13:48:53] <EatPotato> how about those "machine generators"?
[13:49:17] <EatPotato> they have settings for different machines. You're probably using inappropriate ones.
[13:51:54] <micges> cnc_engineer: can you pastebin gcode file somewhere ?
[13:52:38] <EatPotato> For example, it guesses the arc as many straight lines, therefore the process is slow.
[13:55:46] <cnc_engineer> the same g-code program runs fast on other controller e.g fanuc etc.
[13:57:23] <micges> let us see that gcode, so we can tell what's the problem
[13:59:05] <micges> cnc_engineer: you are operating in mm or in ?
[14:00:48] <cnc_engineer> in mm
[14:03:34] <micges> at top of your gcode file insert line: G64 P0.01
[14:04:20] <micges> then your machine will set in continous mode with maximal deviation of path 0.01 mm (you can't see difference)
[14:04:40] <micges> machine motion will be much smoother
[14:04:44] <micges> and faster
[14:07:18] <archivist> the explanation behind that http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Trapezoidal_Velocity_Profile_Trajectory_Planner
[14:08:56] <micges> archivist: thanks for the link, I didn't know about that page
[15:27:57] <cradek> better fix is to fix the cam so it uses g2/g3 for arcs
[17:50:41] <EatPotato> latency test "10'000/12'000" Is it OK?
[17:51:29] <EatPotato> Can I get a network adapter for my machine and connect it to the network/laptop?
[17:53:50] <EatPotato> jepler: ´╗┐latency test "10'000/12'000" Is it OK? Can I get a network adapter for my machine and connect it to the network/laptop?
[18:16:11] <pjm__> EatPotato 10000-12000 is fine for latency test, how long did u leave it running for?
[18:36:38] <dmess> hi all
[18:42:32] <EatPotato> pjm__: few minutes, tar.bz2+glxgears
[18:42:43] <EatPotato> it's ASUS's laptop
[18:43:36] <EatPotato> I thought about the connection through the network where available. But we might not have a network card for our machine.
[18:49:46] <pjm__> i'd leave it running over night just in case the laptop does something odd every 10 mins or whatever
[18:49:48] <pjm__> just to get an idea
[18:50:37] <EatPotato> pjm__: I have been told it switches off the acpi, so Im scared to leave it with real-time kernel so long for a while.
[18:51:55] <pjm__> why? will it melt? plus if u are running a long cnc job with EMC2 u will have to leave it a while anyway
[18:54:36] <EatPotato> pjm__: yeah, I will do that. But I'm pretty sure in that test's results
[19:03:15] <MrSunshine> how high rpm can a stepper run at?
[19:03:27] <MrSunshine> noticed the rpm depends alot on the voltage :)
[19:06:03] <EatPotato> MrSunshine: it's probably depends on a machine's parameters
[19:12:40] <jmkasunich> * jmkasunich is dragged kicking and screaming into the 21st century
[19:20:40] <jmkasunich> anybody in here use PayPal as a seller?
[19:20:50] <eric_unterhausen> I have
[19:21:26] <eric_unterhausen> I've also heard that it isn't much fun
[19:21:36] <jmkasunich> do you take any precautions to keep them from fscking with you (for example, a checking account _just_ for paypal, so they can't get their claws on your main account)>
[19:21:52] <eric_unterhausen> yes, separate accounts
[19:22:13] <eric_unterhausen> not just them, but the scammers too
[19:22:20] <jmkasunich> the fscking bastards at ebay (may they rot in hell), no longer permit you to accept checks or money orders
[19:22:39] <jmkasunich> I am this close to never selling anything on ebay ever again
[19:22:44] <BigJohnT> craigslist
[19:22:49] <eric_unterhausen> that doesn't really bother me much
[19:22:56] <jmkasunich> nowhere near the coverage compared to ebay
[19:23:07] <BigJohnT> nope
[19:23:10] <jmkasunich> I want to sell a height gage
[19:23:34] <dmess> digital??
[19:23:34] <eric_unterhausen> something like that, I would have no problem on ebay w/paypal
[19:23:43] <eric_unterhausen> it's the big dollar items that scare me
[19:23:48] <jmkasunich> if I hadn't spent the last 1/2 hour or more making up a nice photo of the gage, and then started creating the auction, I'd just say screw it
[19:23:58] <jmkasunich> not digital, vernier
[19:24:01] <jmkasunich> brown and sharpe
[19:24:17] <eric_unterhausen> I've sold a couple thousand dollars on ebay, not a big seller, but no probs
[19:24:20] <dmess> naw got 1 of those already... ;(
[19:25:03] <jmkasunich> my concern isn't the actual transaction, I've accepted personal checks for bigger sums and shipped without waiting to clear (if I got good vibes from the buyer)
[19:25:10] <dmess> im waiting for the clowns at work to 5s a microheight
[19:25:29] <jmkasunich> I'm just reluctant to open a paypal account and give them a bank account number
[19:25:51] <jmkasunich> I
[19:25:53] <eric_unterhausen> we had a savings account that isn't linked to the checking
[19:26:10] <eric_unterhausen> so used that one
[19:26:29] <jmkasunich> I'd much rather deal with a guy who wants to steal my $40 or so height gage than a corporation against which you have virtually no recourse when they screw something up
[19:26:43] <dmess> so far my account thats hooked to paypal has been safe as has the c/card even though i have put in for investigations for a few reported things that never showed up on the card
[19:27:16] <jmkasunich> paypal needs a credit card number and a bank account number, right?
[19:27:18] <eric_unterhausen> it seems worth it to me, but I have lots of things I'd like to sell
[19:27:37] <BigJohnT> * BigJohnT wanders out to the garage to run some legtricity to the compressor
[19:27:38] <eric_unterhausen> yes, and they make a deposit to your bank account to make sure it works
[19:27:41] <dmess> yes and you have to get confirmed residence
[19:27:47] <dmess> yes
[19:28:34] <eric_unterhausen> I was going to open a small account at the credit union for paypal
[19:28:42] <eric_unterhausen> maybe I still should
[19:28:45] <jmkasunich> I should do something like that
[19:28:50] <cradek> jmkasunich: unless an item is extremely special and I don't think I'll find another chance, I just skip auctions that don't accept paypal because it's such a huge pain otherwise.
[19:28:52] <jmkasunich> problem is, I can't do it today
[19:29:13] <jmkasunich> cradek: yeah, I know my odds of selling are better if I accept paypal
[19:29:37] <jmkasunich> I just want to minimize my risk of being one of the people who get screwed by paypal
[19:29:49] <cradek> I understand completely
[19:29:52] <eric_unterhausen> especially skip non-paypal now because western union doesn't sell on-line money orders
[19:30:08] <eric_unterhausen> jmkasunich, don't think that's how it works
[19:30:21] <eric_unterhausen> actually more likely to get screwed as a buyer
[19:30:43] <eric_unterhausen> you can always change your bank account on monday
[19:30:45] <jmkasunich> the buyer can never get screwed for any amount in excess of the transaction value
[19:31:26] <eric_unterhausen> I think the people that get screwed for big $ also had big paypal accounts
[19:31:42] <eric_unterhausen> I have heard of various scams for buyers
[19:32:06] <jmkasunich> I don't care if I get stiffed for the value of some auction - I just want to be double damned sure that some idiot at paypal can't do something stupid and get 10x that amount out of my account
[19:32:11] <eric_unterhausen> and, the ever popular password stealing spyware
[19:32:27] <eric_unterhausen> I have never heard of that happening
[19:32:34] <eric_unterhausen> in the way that you imply
[19:32:43] <jmkasunich> I may be paranoid
[19:32:59] <eric_unterhausen> I understand
[19:33:01] <dmess> hey but they are out to get me..
[19:33:12] <jmkasunich> but they way I see it, if paypal has the number for an account that contains $1K, nothing stops them from taking $1K from it except their own skills and honesty
[19:33:17] <eric_unterhausen> I took our checking off of it because I thought the danger was a little too big
[19:33:54] <eric_unterhausen> that, and the desire to stay in business
[19:34:05] <dmess> i've had nothing but good results and service so far
[19:34:23] <eric_unterhausen> you can find horror stories, no doubt
[19:34:34] <eric_unterhausen> but they generally are more than a little garbled
[19:34:46] <eric_unterhausen> and they involve some big dollars
[19:35:09] <dmess> i had a bout of alcohol and e-bay 1 nite and ended up with 8 martin backpacker guitars ;)
[19:35:25] <eric_unterhausen> people run substantial businesses using paypal, there are going to be some problems now and then
[19:35:50] <eric_unterhausen> I always wanted _one_ of those
[19:36:08] <dmess> i got a black 1 left
[19:36:12] <eric_unterhausen> my wife ended up with two playstations
[19:36:32] <eric_unterhausen> I told her she couldn't bid on ebay any more
[19:37:11] <dmess> i wanted 2 1 for me and 1 for my son... his is now an electrified original martin and mine is accoustic
[19:37:45] <dmess> had a heck of a x-mas i gave away guitars ;)
[20:10:59] <jmkasunich> dmess: you know you want it: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=180350579336
[20:11:58] <jmkasunich> I just traded up - bought this one: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=170320442566
[20:14:09] <dmess> mine is a Starrett also... you selling a nice "light" granite slab??
[20:14:41] <jmkasunich> nopr
[20:14:41] <dmess> my son's will love see'ing that show up at the house im sure LOL
[20:15:06] <dmess> we hauled the hardinge into the basement last summer
[20:16:34] <dmess> there's 1 coming available @work but its 8' x 6' x 3' so not even managable til i get a proper shop
[20:17:11] <jmkasunich> granite slab?
[20:18:09] <dmess> surface plate.
[20:18:50] <dmess> this is a decommisioned CMM with drives and touch probe
[20:19:19] <dmess> its just too sweet to pass up.. but i have NO where to put in
[20:38:18] <gene_> hey guys, great if warm day here, but have a gcode problem
[20:39:05] <gene_> what is the syntax to receive a list of vars from a call?
[20:46:21] <alex_joni> gene_: there are some global vars
[20:46:24] <alex_joni> which you could use
[20:50:00] <gene_> I've setup a list at the top of the file, using #30 and up, passing them in the call, but the sub isn't getting anything
[20:51:23] <gene_> Humm, I'll bet the call oword is the same as the sub/endsub, but how then do I chain them for repeat calls in the main code?
[20:51:55] <gene_> can I repeat the o100 call [list of vars] in the main code?
[20:52:33] <gene_> I'll see what upchucks
[20:59:12] <gene_> Ok, got it, my math sucks. :-) Now all I have to do is make it do it for 5 rows
[21:00:28] <gene_> humm, it should be doing 5 rows of 10 holes, but isn't, my math again I spose.
[21:05:24] <alex_joni> good night all
[21:26:01] <SWPLinux> gene_: when you pass vas into a subroutine, they have numbers #1-#10
[21:26:07] <SWPLinux> s/vas/vars/
[21:27:07] <SWPLinux> so if you do something like o100 call [#20] [#30] [#117+2*#118] ...
[21:27:21] <SWPLinux> then #1 in the sub will start out at the value of #20
[21:27:29] <SWPLinux> etc.
[21:30:55] <alSMT_> jepler: is stepconfig "dirhold and setup" 50000/50000 the right timing for Gecko 210 or does it not mater?
[21:32:51] <SWPLinux> damn! woohoo!
[21:33:03] <SWPLinux> our flight tomorrow is cancelled
[21:33:45] <SWPLinux> the good news is that we're stuck in Miami, and the newly booked flight leaves at 1:15 PM instead of 6:00 AM
