[02:09:31] <Deejay> moin
[02:29:52] <ssi> weeee, home
[02:30:21] <ssi> holy balls I'm tired
[03:38:14] <MacGalempsy> Evening
[06:18:09] <MacGalempsy> Anyone up?
[06:19:18] <jthornton> nope
[06:19:28] <gonzo__> no, it went down hours ago
[06:20:00] <Jymmm> gonzo__: Viagra.com
[06:20:02] <MacGalempsy> :)
[06:20:41] <MacGalempsy> Any cool projects going on?
[06:20:47] <gonzo__> just think about 5axis millers
[06:21:28] <MacGalempsy> We just moved to nw arkansas
[06:21:58] <jthornton> some nice bike riding roads over there
[06:22:43] <MacGalempsy> Yes! Still dealing with selling the old house
[06:23:11] <MacGalempsy> Okc to Fayetteville is getting to be an old drive
[06:23:40] <jthornton> we like staying at the Hub near Jasper when we go down there
[06:24:11] <MacGalempsy> Do you float the buffalo?
[06:24:42] <jthornton> I don't float any more
[06:25:36] <MacGalempsy> The fall colors are great
[06:27:24] <MacGalempsy> What kind of bike do you ride?
[06:27:58] <jthornton> usually my GL1800 but often my Spyder RT
[06:28:53] <MacGalempsy> You coming down for bikes blues and bbq?
[06:29:56] <jthornton> no, we are going to Kentucky for a Spyder thing
[06:30:24] <jthornton> I don't like going to big events... just too crowded
[06:30:32] <MacGalempsy> I havent been in 7 years or so
[06:30:48] <MacGalempsy> They say its out of control
[06:34:24] <MacGalempsy> So its been about a year since I last worked on the cnc
[06:34:57] <MacGalempsy> Has the wizard been updated on the latest build?
[06:35:46] <jthornton> which one?
[06:36:31] <MacGalempsy> I think its a mesa 7877 if I remember right
[06:37:22] <MacGalempsy> The electrician cant be there for a few weeks
[06:38:44] <jthornton> that would be Pncconf and yes it gets regular updates
[06:39:39] <MacGalempsy> Very cool. I hope this attempt at getting it going is successful
[06:42:51] <MacGalempsy> Well its bed time here. Have a good day guys.
[07:29:42] <lair82> Good Morning Gentlemen, We have a big issue with main utility power in our area, frequent power outages, and was wondering what would be the best course of action to protect the pc's in my machines. Over the weekend we we had a decent storm come thru, and this morning all of the machines were off. When it came to the one turning center with linux on it, I couldn't get it to start, it won't boot up.
[07:30:33] <Tom_itx> good surge protectors along with a UPS
[07:30:52] <lair82> I cycled the power, and now it won't even attempt to start. I'm thinking the MB is torched. I see DIN rail mount surge protectors, is that the way to go?
[13:49:02] <Loetmichel> Jymmm: that only works if the machine has a flat bootom
[13:49:24] <Loetmichel> i personally like the roller "shoes" better.
[13:53:55] <SpeedEvil> I just use my hoverboard.
[13:56:41] <CaptHindsight> SpeedEvil: do you place the board under the machine or do you hover it over it and drop sky hooks?
[14:04:07] <Loetmichel> CaptHindsight: he lifts the machine with one hand and shoves the board unter with the other ;-)
[14:06:03] <archivist> I shift lumps with rollers and

[14:11:37] <CaptHindsight> http://www.tehpear.com/pictures/other/Machinery%20dollies%20in%20action%20003%20%28Medium%29.jpg looks like some DIY dollies used here
[14:12:10] <Jymmm> Loetmichel: Over than a given. What machine isn't going to have a flat bottom that sits/mounts to the ground?
[14:12:20] <Jymmm> s/over/other/
[14:13:26] <CaptHindsight> http://www.machineryskates.com/img/slider/slide3.jpg maybe some thing like this where the bottom isn
[14:13:37] <archivist> lots just have feet/legs of some sort
[14:13:47] <Jymmm> ah
[14:13:54] <archivist> I put planks between legs/feet to allow use of rollers
[14:14:59] <Jymmm> Yeah, that's what I would do.
[14:15:11] <Loetmichel> a lathe for example
[14:15:16] <Loetmichel> or one that has machine feet
[14:15:43] <Jymmm> couple of 2x6's would seem to do the job
[14:16:30] <archivist> I use builders planks, nice and wide
[14:17:16] <Jymmm> We're talking a one-off move. Unless I could borrow those fancy $200+ dollys/jacks, it's probably not gonna happen.
[14:19:23] <Jymmm> I guess one could use those car dolllys that sit under the tires
[14:20:40] <Jymmm> Something liek this:
http://www.jegs.com/images/photos/400/464/464-2-1016-35.jpg or this
http://i00.i.aliimg.com/photo/210191567/Wheel_dollies.jpg
[14:20:57] <Jymmm> (load distributed)
[14:23:11] <Loetmichel> Jymmm: whre is the problem to bend some 10mm steel plate and get a bunch of 6001 bearings and a bit of fitting round stock and make the dollys yourself?
[14:23:18] <Loetmichel> its no wizardry
[14:23:32] <Jymmm> I sorta like these dues to the tubular steel, you could connect them together by slipping a smaller tube inside and use a hitch pin or bolt.
http://www.northerntool.com/images/product/2000x2000/148/148803_2000x2000.jpg
[14:23:41] <Loetmichel> or use fitting u-steel snipplets
[14:23:49] <Jymmm> Loetmichel: I can't picture what you just descrbied.
[14:24:16] <Loetmichel> U steel, drill 4 28 mm holes in the sides
[14:24:25] <Loetmichel> flanges
[14:24:29] <Loetmichel> 2 left, 2 right
[14:24:52] <Loetmichel> on the late, take 30mm round steel, make 10mm shafts on the ends
[14:25:16] <Loetmichel> press one side bearing in, out the 20mm "wheel" in , press the other bearing in
[14:25:17] <Jymmm> Loetmichel: No lathe for one.
[14:25:34] <Tom_itx> what are you moving?
[14:25:42] <Jymmm> Tom_itx: Nothing
[14:25:51] <Tom_itx> unfortunately the interweb was unplugged here all morning
[14:26:32] <Loetmichel> so use some fitting pipe and a 10mm round stock
[14:26:39] <Loetmichel> to get the middle up to 30mm
[14:27:13] <Loetmichel> i.e some 30mm pipe, then some pipe that fits snug in there, down to 10mm inner diameter
[14:27:32] <Loetmichel> and put the 10mm round stock thru the bearings AND the tubes
[14:27:34] <Loetmichel> works also
[14:28:44] <Jymmm> Loetmichel: and attach the 30mm pipe how?
[14:28:54] <Loetmichel> by nothing
[14:29:09] <Loetmichel> just by the wideness of the u steel
[14:29:29] <Jymmm> Loetmichel: And how much does this all cost if none of it is on hand?
[14:29:38] <Loetmichel> a few quid
[14:29:48] <Loetmichel> the bearings are less than 2 eur each
[14:29:57] <Jymmm> Loetmichel: and what prevents the bearings from coming off?
[14:30:20] <Loetmichel> the pressure needed to press them into the u profile
[14:30:53] <Jymmm> Sounds too complex. I'll stick with plank and dowels.
[14:30:59] <Loetmichel> but you can use M10 *150 screws in there and a nut to prevent the "shaft" from coming out
[14:31:14] <Loetmichel> do as you whisch
[14:31:16] <Loetmichel> whish
[14:31:57] <Loetmichel> the andvantage of these machine rollers is that they can be steered
[14:32:08] <Loetmichel> which can not be done by the dowels
[14:32:39] <Jymmm> We've moved 1200lb safes using rods, just psoitioning then at varoius angles allows for a bit of steering.
[14:32:59] <Jymmm> Mind you all solid flat bottoms of course.
[14:33:54] <Jymmm> The bitch is when you need to move sideways 1/4" =)
[14:34:10] <cpresser_> crowbar ftw :)
[14:34:20] <Jymmm> cpresser_: BIG ASS crowbar =)
[14:34:35] <Jymmm> cpresser_: But sometimes this in person's home
[14:56:30] <Jymmm> cpresser_: Then it's "Put this 1200lb safe in this cubby hole that only has 1/4" clearance, but don't fuck up my hard wood floors"
[14:57:24] <cpresser_> Jymmm: my response would be 'go fuck yourself'. or 'pay me for the special tools i need'
[14:57:35] <Jymmm> cpresser_: You can mae more money in the installation than the sale of the safe =)
[14:58:05] <Jymmm> Safe $2200, Delivery and Instalation $4500 =)
[14:59:11] <Jymmm> and they'll pay it as their putting into it like $40K worth of junk =)
[15:00:22] <Jymmm> You could toss a couple of bodies in these safes =)
[15:01:11] <Jymmm> One of the other guys bet me he could break out of one with only a pocket screwdriver, so I locked his ass in the safe and spun the dial.
[15:01:36] <Jymmm> The bastard was out in 15 minutes =)
[15:02:30] <cpresser_> how did he do it?
[15:03:24] <Rab> Mechanism exposed inside?
[15:03:24] <Jymmm> cpresser_: With ne of these
http://www.pocketscrewdrivers.com//v/vspfiles/photos/2032RV-2T.jpg
[15:03:45] <Jymmm> cpresser_: Safes are not prisons. They are made to keep people from getting in, not out =)
[15:04:38] <Jymmm> cpresser_: That was the REAL lesson he was teaching me.
[15:05:11] <Jymmm> PLus he was a damn good lock/safe smith.
[15:06:13] <Jymmm> There wasn't a lock he couldn't pick. I even specially keyed up a lock and instead of his normal 30seconds, it took him 2 minutes.
[15:06:57] <cpresser_> lockpicking is fun. I have the tools, but lack the skills. it takes me 30min to open one default lock
[15:07:26] <Jymmm> 30s for him was slow. Most of the time 12s.
[16:13:01] <Deejay> gn8
[16:22:29] <Tom_itx> Jymmm roll them on air bags
[16:23:02] <Tom_itx> it's how they got alot of junk back in the water in New Orleans
[17:18:10] <anarchos2> hi
[17:18:55] <anarchos2> so i bought a touch plate, hooked it up and it works somewhat (i can see the pin working in halshow) but i'm at a loss at how to actually do it....
[17:20:19] <anarchos2> basically it has two wires, one hooked into a 5V source, one hooked into paraport pin 15. then on the plate side there's the plate which is connected to the wire that goes into pin 15, then the other wire is an alligator clip.
[17:21:06] <anarchos2> i'm assuming i'm suppost to hook the aligator clip into my spindle or wherever, so when the took touches it completes the circuit...but when i do that my limit switches get errors and my Z axis twitches...
[17:24:54] <CaptHindsight> anarchos2: is anything else connected to pin 15?
[17:25:43] <CaptHindsight> anarchos2: in your HAL file or in any other way? (used for a limit or home switch, etc etc)
[17:26:33] <CaptHindsight> anarchos2: it might be a good idea to pastebin your HAL and INI as well if you're not sure
[17:27:13] <anarchos2> negative, pin 15 is all on it's own
[17:28:03] <CaptHindsight> anarchos2: do you have access to a multimeter?
[17:28:14] <anarchos2> yup
[17:28:42] <anarchos2> i have on sitting beside me
[17:29:21] <CaptHindsight> whats the resistance across the two wires of the touch probe when the probe is in and not in contact?
[17:29:47] <CaptHindsight> so unhook it from power and the LPT pin 15
[17:29:58] <CaptHindsight> and then measure
[17:30:32] <CaptHindsight> lets find out if the probe has a series resistor
[17:30:47] <anarchos2> ok, just a sec
[17:32:53] <CaptHindsight> anarchos2: are you using a breakout board for the LPT port?
[17:33:28] * JT-Shop is pooped out
[17:34:13] <anarchos2> CaptHindsight, yup
[17:35:50] <anarchos2> so resistance between the plate and the black wire (which are directly connected is 0.65 ohm, resistance between the alligator clip and the white wire (directly connected) is 0.42ohm, so i think there is no resistor
[17:35:52] <CaptHindsight> anarchos2: we need to find out how to wire up the probe based on if it is just a normally open switch switch and how your BOB is designed
[17:36:06] <CaptHindsight> I agree
[17:36:19] <anarchos2> hmm
[17:37:30] <anarchos2> it's weird because my limit switches are mounted with double sided tape (and the bit that actually touches is plastic), so i don't think it's actually a grounding issue
[17:37:45] <anarchos2> must be the BOB leaking voltage to other pins somehow?
[17:37:51] <CaptHindsight> is pin 15 on your BOB a resistor in series with an opto?
[17:37:59] <CaptHindsight> which BOB is this?
[17:38:55] <CaptHindsight> some BOB's have pullup resistors on the opto inputs
[17:39:29] <anarchos2> http://cnc4pc.com/Tech_Docs/C35S_R1_USER%20MANUAL.pdf
[17:39:36] <anarchos2> CNC4PC.com C35S
[17:42:19] <anarchos2> it's weird because if i touch the alligator clip to the plate, everything works fine, no limit switch errors, etc...it's only when i'm grounding through the machine itself, which leads me to believe i've somehow not done something correctly
[17:42:24] <CaptHindsight> see page #8
[17:43:56] <anarchos2> yeah seems like that first diagram is saying i'm doing things correctly
[17:44:24] <CaptHindsight> anarchos2: when the probe is touching a surface does it close the connection between the white and black wire?
[17:46:02] <anarchos2> i'm not exactly sure what you mean...
[17:46:12] <CaptHindsight> have a pic of the probe?
[17:46:57] <CaptHindsight> what does the probe do? Is it a normally open switch with a black wire on one side and white on the other contact?
[17:48:08] <CaptHindsight> is the body of the probe conductive? Is there electrical continuity between any of the wires and the body of the probe that goes into the spindle?
[17:48:24] <anarchos2> ah sorry, it's actually a touch plate, not a probe
[17:48:43] <cpresser_> 23:59 < anarchos2> so i bought a touch plate, hooked it up and it works somewhat (i can see the pin working in halshow) but i'm at a loss at how to actually do it....
[17:48:50] <cpresser_> you neet to connect it motion.probe-in
[17:48:52] <cpresser_> (or similar)
[17:49:12] <CaptHindsight> so whats the theory of operation? what happens when the plate touches the surface?
[17:50:11] <anarchos2> so basically it's a conductive plate, no switch or anything.
http://imgur.com/CvmPX8i
[17:51:07] <anarchos2> in theory (how i'm assuming it works) is that i connect the alligator to my spindle somewhere, then when the tool touches the plate, the circuit is closed
[17:51:40] <anarchos2> basically grounding through the machine itself
[17:56:03] <CaptHindsight> see page #12
[17:56:56] <anarchos2> hmm
[17:57:43] <anarchos2> so i need a resistor in there
[17:58:03] <CaptHindsight> which is only going to work if the tool is insulated from ground
[17:58:32] <anarchos2> by the looks of it, it is not. :/
[17:58:47] <CaptHindsight> your tool is most likely not :)
[17:59:04] <CaptHindsight> i love these horrid docs
[17:59:07] <anarchos2> well, shoot.
[17:59:51] <anarchos2> i wonder if i can find a 2.2k resistor locally, just to try
[17:59:58] <CaptHindsight> in your situation the black wire connects to the conductive pad
[18:00:19] <anarchos2> yes
[18:01:05] <anarchos2> so blackwire should be going to grn on my BOB, white wire should be going to +5 and pin 15 with a 2.2k resistor, i think?
[18:01:06] <CaptHindsight> so you would wire the black to pin 15 with a 2.2K from pin 15 to 5V
[18:02:05] <CaptHindsight> so pin 15 is pulled High to 5V when the tool is not in contact with the plate
[18:02:32] <anarchos2> oh i see, because of my grounding issue?
[18:02:43] <CaptHindsight> when the tool comes in contact with the plate it will pull pin 15 low
[18:03:15] <CaptHindsight> but you need a good ground connection between the tool and the ground for the BOB
[18:03:42] <anarchos2> hmm
[18:07:29] <ssi> the mosquitoes the mosqitoes, the mosquitoes the mosquitoes
[18:07:38] <ssi> the mosquitoes ate my dead ass up
[18:07:40] <CaptHindsight> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Touch_Probe
[18:07:55] <CaptHindsight> was pretty bad here yesterday as well
[18:08:53] <CaptHindsight> anarchos2: net probe parport.0.pin-15-in-not => motion.probe-input since the signal is inverted (starts at 5V when probe is not in contact, goes to 0V when the probe makes contact)
[18:09:18] <anarchos2> yeah sweet, thanks
[18:09:18] <CaptHindsight> also called Active Low
[18:09:46] <anarchos2> i'm gonna have to see if i can scrounge up a resistor somewhere...living in a resort town has it's drawbacks :P
[18:09:56] <anarchos2> i wonder if the autoparts store might have some?
[18:10:08] <CaptHindsight> radio Shack
[18:10:44] <jdh> what resort town?
[18:10:49] <anarchos2> whistler
[18:10:50] <ssi> take something apart :)
[18:10:56] <anarchos2> no radio shack for 100km :P
[18:11:19] <CaptHindsight> yeah, creative scrounging
[18:12:14] <jdh> ssi: how many resistors within 20ft of you?
[18:12:28] <ssi> literally tens of thousands
[18:12:35] <anarchos2> lol :P
[18:12:47] <anarchos2> maybe i should buy a resistor kit
[18:13:01] <anarchos2> on hold with the autoparts store
[18:13:08] <jdh> not likely
[18:13:22] <jdh> repair shop or something maybe. teevee store
[18:13:51] <ssi> let me revise that upward
[18:13:54] <ssi> literally hundreds of thousands
[18:13:55] <ssi> :(
[18:13:59] <jdh> wow
[18:14:30] <ssi> this is within arm's reach of my computer chair
[18:14:31] <ssi> https://pbs.twimg.com/media/ByLBkcsIYAAfINC.jpg:large
[18:14:49] <jdh> wtf are you going to do with that?
[18:14:56] <ssi> let's put it this way
[18:15:02] <ssi> they're a dime apiece
[18:15:07] <ssi> or $7 for a reel of 5k
[18:15:29] <ssi> so I design with common values, and I buy reels
[18:15:43] <ssi> I have thirty or forty reels aronud the house
[18:16:18] <anarchos2> welp, autoparts store has informed me that there's a new electrical supply place in town!
[18:16:22] <jdh> where do you get $7 reels?
[18:17:53] <ssi> http://www.digikey.com/product-detail/en/RC0603JR-071KL/311-1.0KGRTR-ND/726677
[18:17:59] <CaptHindsight> as a child we would ride the trolley bus to the electronics parts store
[18:18:08] <ssi> $6.65 :)
[18:18:18] <jdh> wow
[18:18:36] <jdh> it would never occur to me to look for a 5k item price break
[18:18:44] <ssi> reel pricing :)
[18:19:00] <jdh> hard to imagine they can make them that cheap.
[18:19:07] <ssi> not much to them
[18:19:15] <jdh> no, but stilll
[18:19:17] <CaptHindsight> well it's surface mount
[18:20:36] <CaptHindsight> http://www.digikey.com/product-detail/en/CF14JT2K20/CF14JT2K20TR-ND/1741321 a bit more for through hole
[18:21:12] <jdh> what form do 5k through hole come in?
[18:21:19] <jdh> neatly arranged or bagged?
[18:21:40] <ssi> tape and reel
[18:22:09] <jdh> oh, it does say that
[18:23:40] <CaptHindsight> heh, Giant Box-O-Resistors
[18:24:00] <Tom_itx> usually cut tape
[18:24:04] <ssi> still, a half penny apiece for through-hole quarter watt resistors is pretty damn cheep
[18:24:10] <jdh> yeah
[18:24:13] <lorenl> hello
[18:24:15] <ssi> Tom_itx: the 5k break is almost certainly an uncut reel
[18:24:18] <jdh> but, I don't need 5k of anything
[18:24:27] <Tom_itx> get em off ebay for cheeeep
[18:24:29] <jdh> I don't need the ~5k of ones I already have
[18:24:45] <ssi> I don't either, but a reel of 0603 resistors is cheap enough and more convenient than keeping up with little bits of cut tape
[18:24:56] <lorenl> I'm working on an old CNC router that uses a DOS program for g-code interpretation
[18:24:59] <CaptHindsight> sell them for $10 per 1K on ebay
[18:25:14] <lorenl> I found the full documentation on it's native language and can control it from a terminal.
[18:25:17] <jdh> lorenl: and you want to switch to linuxncc?
[18:25:40] <lorenl> I think what I might need next is a g-code interpreter I can use to make a custom translator.
[18:26:14] <jdh> what is its native language?
[18:26:19] <lorenl> I'm looking at LinuxCNC to see what it could do for me.
[18:26:35] <jdh> most likely everything.
[18:27:35] <lorenl> It's documented in this PDF.
[18:27:39] <lorenl> http://bit.ly/1pb2SEi
[18:27:53] <lorenl> I'm successfully running the sample programs from it starting on page 21.
[18:28:42] <lorenl> I'd like to avoid replacing the motor controller board on it just to get native G-code support if possible.
[18:31:14] <jdh> it looks like you could probably get a $15 breakout board and drive it directly from a parallel port with linuxcnc
[18:38:35] <lorenl> This is using 4A bipolar steppers with limit switched and a relay box for the router.
[18:39:39] <jdh> use the existing drivers, just bypass the controller using the diagram on the last page.
[18:46:00] <lorenl> OK, I'll look at that as an option.
[18:46:33] <jdh> vs?
[18:46:47] <lorenl> Last question on that, is there any software g-code virtual machines I could look at as an alt?
[18:47:14] <jdh> that does what?
[19:02:08] <lorenl> I'm picturing something like how Ghostscript software is used a Postscript interpreter which then renders the output into another format for Printer drivers.
[19:02:33] <lorenl> Is there something that can interpret g-code and try and rerender it in another language.
[19:03:44] <jdh> not that I know of. Doesn't seem like it would solve a general problem. Usually you want to convert other things to gcode
[19:04:23] * SpeedEvil wants a G-code to Klingon poetry converter.
[19:04:31] <jdh> might try the reprab/grbl/wtf guys.
[19:04:39] <jdh> SpeedEvil: vogon poetry
[19:13:45] <Jymmm> Tom_itx: Need airbag hockey table thingy
[19:16:08] <Tom_itx> i'm sure you've seen those round air bags they use...
[19:25:22] <cpresser_> SpeedEvil: ask shakespeare. his native language is klingon
[19:32:13] <Jymmm> cpresser_: Hab SoSlI' Quch
[19:33:06] <PetefromTn_> here's a stupid question for you guys LOL
[19:33:26] <Jymmm> PetefromTn_: No, we won't touch you in your special place.
[19:33:41] <PetefromTn_> I have a custom part I machined that has some elaborate contours and curvatures on it.
[19:33:54] <PetefromTn_> I designed it in my CAD and made and sold quite a few of them now.
[19:34:20] <PetefromTn_> Today I got a call from a customer who basically wants me to shrink the design in vertical height but keep the shape.
[19:35:02] <PetefromTn_> I was wondering if there is some cad feature or otherwise feature that will allow me to MORPH the design to be shorter yet retain the same look without having to redraw everything....
[19:35:38] <PetefromTn_> just to save some time because this is not the first time I have had a request like this.
[19:35:50] <Jymmm> You can either scale in alll axis, or distort it
[19:36:05] <PetefromTn_> okay...how
[19:36:11] <Jymmm> This is without evr seeing the part.
[19:36:20] <Jymmm> Need to see it to say
[19:36:21] <PetefromTn_> lets assume it is a .dxf 2d file
[19:36:31] <Jymmm> just post a pic
[19:36:36] <PetefromTn_> why?
[19:36:54] <cpresser_> use the scale operation of autocad. done.
[19:36:59] <PetefromTn_> can you scale in a single axis or something like that.
[19:37:01] <Jymmm> To give you ideas other than the two I already said
[19:37:27] <PetefromTn_> scale in autocad from what I know of it works in both directions.
[19:37:35] <Jymmm> cpresser_: he wants to scale, but only in ONE axis.
[19:37:39] <PetefromTn_> is there some way to scale vertically?
[19:37:52] <XXCoder> Z scale?
[19:37:53] <cpresser_> google 'autocad scale single axis'
[19:37:59] <cpresser_> finds a lot of solutions.
[19:38:14] <cpresser_> i know how to do it in inkscape and vcarve, they both have options for that
[19:38:14] <Jymmm> cpresser_: but that's all distorted.
[19:38:27] <cpresser_> Jymmm: sure it is
[19:38:35] <Jymmm> it's going to E X P A N D
[19:38:47] <cpresser_> thats the idea behind scaling :)
[19:39:07] <cpresser_> perhaps, what you want is node editing. moving a bunch of nodes at a time.
[19:39:31] <PetefromTn_> googling..
[19:39:35] <Jymmm> cpresser_: yes, maintining ratio on both acis, but he doesn't want to scale X, just Y
[19:40:01] <cpresser_> http://imgur.com/4xFTI47
[19:40:33] <Jymmm> cpresser_: he says it has elaboart curves, but doens't want to shoe it. *shrug*
[19:40:37] <Jymmm> show*
[19:40:51] <cpresser_> http://imgur.com/JtCVZNs
[19:41:21] <PetefromTn_> what program is that?
[19:41:22] <cpresser_> thats how i scale in one direction. however, that does also distort the radius
[19:41:31] <zeeshan|2> i am quiet impressed by the girls at school that im teaching
[19:41:33] <Jymmm> cpresser_: Undo the scale, then hit CTRL+A and scale then fucker =)
[19:41:35] <cpresser_> vcarve-pro (non-free software)
[19:41:36] <PetefromTn_> I figured it would distort radii.
[19:41:39] <zeeshan|2> with little instruction
[19:41:44] <zeeshan|2> they know how to machine ap art on a mill
[19:41:50] <zeeshan|2> without ever using a mill before
[19:42:12] <zeeshan|2> some guys are ok
[19:42:20] <zeeshan|2> but most make major errors
[19:42:24] <zeeshan|2> and ruin their part
[19:42:25] <cpresser_> corel-draw or illustrator also has those option (unlink axes bevore scaling)
[19:42:46] <Jymmm> cpresser_: You only scaled one element, not the whole part =)
[19:42:48] <cpresser_> my guess would be that virtually any CAD programm can do it
[19:42:58] <cpresser_> Jymmm: in the fist picture, yes
[19:43:00] <roycroft> i found when i was first taking machining courses that the majority of the guys were arrogant, would not listen, and were reckless on the machines
[19:43:09] <Jymmm> cpresser_: I know =)
[19:43:14] <roycroft> and the women (there were only a couple) were thoughtful and attentive
[19:43:26] <roycroft> and they made better parts, faster, than most of the guys
[19:43:30] <zeeshan|2> roycroft: isn't that crazy?
[19:43:33] <zeeshan|2> how you notice that trend
[19:43:41] <Jymmm> cpresser_: What's the triple red nides mean?
[19:43:47] <Jymmm> nodes*
[19:43:52] <roycroft> i think part of it is a macho thing
[19:44:07] <roycroft> it would be interesting to see that same group of guys in a machining class without any women
[19:44:14] <roycroft> they would probably be a little more chill
[19:44:21] <zeeshan|2> next couple of groups are all guys
[19:44:37] <cpresser_> same part again, this time original and scaled version side by side:
http://imgur.com/LDUwbDQ
[19:44:42] <roycroft> but get a woman in the class and they all want to show off
[19:44:46] <zeeshan|2> aha
[19:44:50] <zeeshan|2> damn guys
[19:44:55] <zeeshan|2> flexing their manhoods all the time
[19:45:00] <cpresser_> Jymmm: those are the nodes i did select.
[19:45:00] <PetefromTn_> cpresser_ Thanks man. I think I found a solution.
[19:45:00] <Jymmm> cpresser_: TY )
[19:45:02] <roycroft> the funny thing is, the women were lesbians
[19:45:09] <roycroft> and the guys did not notice
[19:45:16] <zeeshan|2> rofl
[19:45:36] <roycroft> i found it entertaining to a degree
[19:45:38] <zeeshan|2> so basicaly the lab consists of teaching them and using a mill within 3 hours
[19:45:40] <roycroft> but also annoying
[19:45:45] <zeeshan|2> and holding 2 tolerances down to .02 mm
[19:45:52] <zeeshan|2> its quite a bit of challenge
[19:45:56] <zeeshan|2> when they dont remember anything about fits
[19:46:03] <roycroft> we started out on a sensitive drill press
[19:46:05] <zeeshan|2> and dont know the controls, or understand job planning or work holding
[19:46:15] <roycroft> and our first work on the mill was without power
[19:46:25] <roycroft> i still remember that project
[19:46:31] <roycroft> and i still have the drill gauge that i made
[19:46:37] <zeeshan|2> nice
[19:46:43] <zeeshan|2> these are mech engs
[19:46:48] <zeeshan|2> so i try to use mech eng knowledge wherever i can
[19:46:54] <zeeshan|2> ie tool stick out is like a cantilever beam
[19:47:06] <zeeshan|2> conventional milling vs climb imagine is using the velocity vectors
[19:47:12] <zeeshan|2> (directions)
[19:47:14] <zeeshan|2> they seem to follow that
[19:47:40] <roycroft> i do a fair amount of project management - civil work
[19:47:40] <zeeshan|2> remind them of right hand rule when they're trying to tighten or loosen something
[19:47:48] <roycroft> i get along with construction crews really well
[19:47:54] <roycroft> because i've worked in the trades
[19:47:58] <roycroft> and i spend time out in the field
[19:48:12] <roycroft> they're used to ivory tower engineers who've never gotten their hands dirty
[19:48:16] <zeeshan|2> its kinda like that at manufacuting facilities
[19:48:20] <roycroft> and don't know how things work in practice
[19:48:22] <zeeshan|2> just opening that door from the office to the floor
[19:48:26] <zeeshan|2> huge change of environment
[19:48:30] <roycroft> yup
[19:48:40] <zeeshan|2> i hate to admit it
[19:48:48] <roycroft> i think every engineer ought to spend a year in the trades before getting licensed
[19:48:51] <zeeshan|2> a lot of engineers i see dont liek to get down and dirty
[19:49:02] <zeeshan|2> yet they think they know it all
[19:49:04] <roycroft> yup
[19:49:11] <zeeshan|2> not much practical experience
[19:49:22] <zeeshan|2> i really got a big smile today
[19:49:30] <zeeshan|2> when one of the students was talking to his friend
[19:49:32] <zeeshan|2> and he's like
[19:49:35] <zeeshan|2> "damn that took so long to do"
[19:49:38] <zeeshan|2> "looked so simple to make"
[19:49:50] <roycroft> so this is a true story
[19:50:04] <roycroft> a couple summers ago i was managing a fiber optic install
[19:50:07] <roycroft> which is what i do
[19:50:25] <roycroft> i was out supervising, and the crew popped a sidewalk lid right next to a utility pole
[19:50:39] <roycroft> then they started digging, and hit a 4 pair phone line that was not located
[19:51:10] <roycroft> the city engineering folks (this was a municipal project) wanted to go design a way of splicing it back together
[19:51:24] <roycroft> i sent a guy to the store to get a ug repair kit
[19:51:33] <roycroft> and he was back in 20 minutes with it done
[19:51:37] <zeeshan|2> hah
[19:51:39] <roycroft> city engineering had plans drawn up the next day
[19:51:56] <zeeshan|2> well the thing about engineering is
[19:51:57] <roycroft> we had already refilled the hole and were forming up to pour the lid
[19:52:01] <zeeshan|2> we're taughing to really think about the problem
[19:52:06] <roycroft> sure
[19:52:07] <roycroft> but
[19:52:10] <zeeshan|2> so sometimes its very easy to overcomplicate/overthink things
[19:52:16] <LeelooMinai> Then you had to open it again:)
[19:52:17] <zeeshan|2> cause lack of practical experience
[19:52:17] <roycroft> someone thought about that problem 75 years ago
[19:52:22] <roycroft> and designed something to fix it
[19:52:30] <zeeshan|2> yes that just sounds like lack of practical exp
[19:52:35] <roycroft> which is available everywhere, because people cut through phone cables every day
[19:52:54] <zeeshan|2> i'd just use some electrical tape
[19:52:56] <zeeshan|2> and call it a day :-)
[19:52:58] <roycroft> we had a bit of a discussion
[19:53:15] <roycroft> in the city manager's office, unfortunately
[19:53:37] <roycroft> i told him that the contractors wanted a change order because of the delay
[19:53:41] <roycroft> which would have cost the city a lot of money
[19:53:58] <zeeshan|2> its _only_ tax payer money
[19:53:59] <zeeshan|2> waste it!
[19:54:00] <roycroft> except i had them fix it with a $40 off-the-shelf splice kit
[19:54:10] <roycroft> and it didn't delay them at all
[19:54:27] <roycroft> municipalities have no money to waste
[19:54:39] <roycroft> they have to scrimp and save every penny they can now
[19:55:07] <roycroft> when the economy crashed in 2008 municipal government got hit harder than almost every other sector
[19:55:17] <roycroft> it was a triple-play slam to them
[19:55:40] <zeeshan|2> doh
[19:55:44] <roycroft> lower tax rates meant less tax revenue
[19:56:01] <roycroft> our state income tax is pegged to the federal tax level, so there was even more of a reduction in tax revenue
[19:56:13] <roycroft> and since everyone was unemployed, demand for services went way up
[19:56:31] <roycroft> a quadrulpe whammy, i guess
[19:56:48] <zeeshan|2> what state
[19:56:55] <roycroft> since the economic collapse meant less business conducted, and an even further reduction in tax revenue
[19:56:55] <roycroft> oregon
[19:57:09] <zeeshan|2> yea an economic crises
[19:57:14] <zeeshan|2> is always a downward spiral for most people
[19:57:15] <roycroft> many states peg their income taxes to the federal tax lelve
[19:57:17] <roycroft> level
[19:57:35] <roycroft> of course, i'm never the hero when i do quick, cheap fixes
[19:57:44] <roycroft> i'm the bad guy who circumvents process
[19:58:16] <roycroft> we had another situation on that same job where some traffic signal control lines were not located accurately
[19:58:32] <roycroft> fortunately, they were not cut, but they were in the way of a vault i neeeded to place
[19:58:42] <roycroft> again, the contractor wanted a change order
[19:58:55] <roycroft> i told him to put a metal plate over the hole and i ordered a different vault that would fit
[19:59:03] <roycroft> and he set the vault later on
[19:59:13] <roycroft> city engineering did not like that either
[19:59:53] <roycroft> and the funny thing is, the reason i project managed that fiber plant was because city engineering not only knew absolutely nothing about fiber plants, they very vocally stated that they did not want to know anything about fiber
[20:00:06] <roycroft> they do water, sewers, and roads, and want to stick to those things
[20:00:40] <roycroft> anyway, the city decided they can't afford an outside project manager any more for these things
[20:00:50] <roycroft> so now engineering do the project management, and write change orders every week
[20:01:10] <roycroft> i just laugh at them
[20:01:19] <zeeshan|2> monopoly!
[20:01:36] <roycroft> well first of all they don't apply any creative energy towards a solution
[20:01:43] <roycroft> and secondly, they are rarely on site
[20:02:01] <roycroft> and the contrators know that, and so they bid low to get the job and know they can make crap up to get change orders left and right
[20:02:20] <roycroft> most of the change orders are completely unnecessary
[20:02:56] <roycroft> so i guess the moral is that you're going to pay up front, or pay even more in the end
[20:05:03] * roycroft is done with his rant about engineers with no practical experience in the real world now
[20:05:16] <roycroft> it's a recurring theme of mine, though
[20:08:12] <jdh> I do manufacturing.
[20:39:22] <Connor> jdh: You have access to any DIN components?
[20:41:21] <Connor> I have some WIELAND Terminal blocks.. and needs some jumpers /
[20:42:05] <ssi> I made a cushion

[20:43:31] <Connor> ssi: Um... Okay....
[20:44:04] <ssi> WHAT
[20:44:06] <ssi> DON'T JUDGE ME
[20:45:09] <Jymmm> /join ##hamradio
[20:45:22] <ssi> you can't make me
[20:52:54] <jdh> connor: screw in or comb things?
[20:53:06] <Connor> http://www.ebay.com/itm/WIELAND-WK-6-U-WK6-U-TERMINAL-BLOCK-/350302317241
[20:53:09] <Connor> I have that.
[20:53:20] <Connor> I need the bars that bridge multiples of those..
[20:54:33] <jdh> how many
[20:55:55] <Connor> Need one for 48v buss.. 4 ganged together... and 4 sets of doubles for AC
[20:57:58] <Connor> I have 2 120v plugs for my setup.. 1 for the spindle itself.. (since it can go up to 16amps) and one for the steppers.. and technically.. one for the PC. but that goes straight into the PC PSU.. So I don't need to do anything with it.
[20:59:35] <Connor> Looking for industrial grade switches now for the power switch for the spindle, steppers, and a rotary one for the coolant.
[20:59:57] <Connor> Was planning on switching the AC on all of those..
[21:00:23] <Connor> But.. I'm not so sure now.. not able to find much.. most of control switches are for 24v
[21:04:29] <jdh> they come in strips of 20
[21:05:37] <jdh> mine are weidmuller, but looks about the same.
[21:08:31] <jdh> https://drive.google.com/file/d/0Bz5kbenmrw4VdXFPUTVqQ0NFRm8/edit?usp=sharing
[21:09:41] <roycroft> you could get some contactors with 24vdc coils to do the switching
[21:09:57] <jdh> my 'share' to picasa seems to have disappeared from my phone
[21:12:58] <jdh> you want manual switches for the spindle/steppers?
[21:13:49] <jdh> you can get relatively cheap 10/20/40A AC SSRs
[21:14:54] <roycroft> those cheap ssrs are not terribly reliable, and they also leak current
[21:15:00] <roycroft> and when they fail they fail closed
[21:15:24] <roycroft> i'm using some on my new brew system control panel, because i have a couple pids that switch on and off almost constantly
[21:15:42] <roycroft> but i put some contactors that are switched separately between the mains and the ssrs
[21:16:11] <roycroft> i was almost paranoid about the control panel
[21:16:18] <roycroft> it has 250vac/50a running through it
[21:16:38] <roycroft> high current + wet sloppy process + drinking beer while brewing = disaster potential
[21:18:13] <jdh> the leaking current can be annoying.
[21:19:20] <jdh> I would not agree that they are reliable though. I have hundreds of them in systems at work and don't recal any failures of that nature.
[21:19:54] <roycroft> i personally haven't had any fail, but i've seen many reports of their failing
[21:20:38] <roycroft> it was a simple matter to put contactors in front of mine
[21:21:13] <jdh> takes a lot more current to close a contactor than an SSR
[21:22:50] <roycroft> yes
[21:23:03] <roycroft> that may be a factor in some applications
[21:23:05] <jdh> I can't think of any high current applications we use though so maybe they are just in friendly environments
[21:23:48] <roycroft> *sigh*
[21:23:59] <roycroft> and we're bombing the crap out of brown people on the other side of the world again
[21:24:05] <roycroft> huge bombing mission going on in syria right now
[21:25:07] <jdh> we are protecting hundreds of thousands of them from the evil doers
[21:25:24] <roycroft> yes, and i agree that it needs to be done
[21:25:34] <roycroft> i guess i'm just pretty tired of the united stats doing all the doing
[21:25:48] <roycroft> i don't mean to get into a political conversation
[21:26:08] <roycroft> i just heard about the bombing and reacted
[21:26:28] <roycroft> process control systems are a much better topic to discuss, i think
[21:27:58] <jdh> I do that all day though
[21:28:16] <jdh> and part of this evening.
[21:28:35] <jdh> I'm not sure if it is worse when they call me with problems, or when they don't and try to 'fix' them themselves.
[21:28:50] <roycroft> my experience is that i prefer neither
[21:29:01] <roycroft> but if i had to choose one i'd rather be called
[21:29:32] <jdh> we run 24x7, only other choice is it sits until I get there in the morning and we are still paying operators.
[21:29:41] <roycroft> i have a kind of nice situation in a way right now
[21:29:46] <roycroft> i carry a pager when i am not at wlrk
[21:29:57] <roycroft> and i get paid a small sum per hour just to carry it
[21:30:02] <jdh> nice.
[21:30:04] <roycroft> if it makes noise i get a lot of money
[21:30:21] <jdh> if carry a work cellphone. I get paid the same either way.
[21:30:22] <roycroft> all that is good, except there are times when i'd rather not have it
[21:30:44] <roycroft> i have a work cell phone but i don't get paid for answering it after hours
[21:30:56] <roycroft> so i don't answer it after hours
[21:31:06] <roycroft> my house has radiant ceiling heat
[21:31:11] <roycroft> so there are heater coils in all the ceilings
[21:31:19] <roycroft> effectively my house is a big faraday cage
[21:31:26] <roycroft> so my cell phone doesn't work in my house
[21:31:34] <roycroft> oddly, my pager does
[21:32:12] <roycroft> i'm sure that has nothing to do with the fact that i get paid to monitor one and don't get paid for the other
[21:32:43] <roycroft> the faraday cage must be tuned to the frequency of my cell phone
[22:46:14] <Connor> I was going for mechanical switch -- already have a 25 amp SSR on the spindle..
[22:56:53] <PetefromTn_> evening folks.
[23:09:30] <XXCoder> yo
[23:47:14] <ssi> hm
[23:47:25] <XXCoder> hey social. whats up
[23:59:00] <ssi> wat
