[00:00:45] <roycroft> i use 12-24 screws in racks a lot more often than 10-32
[00:01:13] <furrywolf> I've never owned a rack. I have several pieces of rackmount equipment, but they just get stacked or used as benchtop equipment.
[00:01:51] <roycroft> i've been rack mounting equipment for decades
[00:02:09] <furrywolf> http://fw.bushytails.net/benchsupply01.jpg or used like that. instant rack! :)
[00:02:12] <roycroft> and we're in an earthquake 4 zone
[00:02:18] <roycroft> i can't stack things in my fiber huts
[00:02:23] <roycroft> they have to be installed very securely
[00:02:24] <zeeshan-mill> furrywolf, not even two racks
[00:02:25] <zeeshan-mill> ?
[00:02:44] <furrywolf> ?
[00:03:19] <zeeshan-mill> nm :P
[00:03:22] <zeeshan-mill> i noticed something
[00:03:27] <furrywolf> rack, as in, a place to install rackmount equipment.
[00:03:28] <zeeshan-mill> if i have the spindle speed at 500 rpm
[00:03:31] <zeeshan-mill> and i try to do g33.1
[00:03:43] <zeeshan-mill> it overshoots, and then reverse the spindle
[00:03:45] <zeeshan-mill> but it doesnt go back up
[00:03:48] <zeeshan-mill> interesting
[00:04:05] <zeeshan-mill> and after that, if i ever execute g33.1 , ill randomly got a joint 2 following error
[00:04:18] <zeeshan-mill> i have to restart linuxcnc, rehome the machine to get it to work
[00:04:18] <furrywolf> as in, it sits there spinning in one place breaking your tap if you weren't cutting air?
[00:04:25] <zeeshan-mill> furrywolf, exactly
[00:04:34] <zeeshan-mill> did i find a bu
[00:04:36] <zeeshan-mill> *bug
[00:04:37] <furrywolf> check that you're getting proper quadrature into hal
[00:04:40] <zeeshan-mill> i am
[00:04:51] <zeeshan-mill> i think :-)
[00:04:56] <zeeshan-mill> i mean the rpm display is correct
[00:05:02] <furrywolf> there's some hal variable that gives the spindle rotations... check that it starts going down.
[00:05:11] <furrywolf> right, but the rpm display doesn't need quadrature...
[00:05:28] <zeeshan-mill> im weirded out that it doesnt error out
[00:05:30] <zeeshan-mill> and stop the spindle
[00:06:32] <furrywolf> I've never actually set up a spindle encoder, so I'm just remembering what I've read, but if it had some problem with the quadrature setup (either hardware or hal), it might do something like that.
[00:07:05] <furrywolf> yeah, spindle turning the opposite way than it thinks it should be turning should be something that gives some kind of error...
[00:07:39] <zeeshan-mill> im sure someone has tried tapping at 500 rpm
[00:07:47] <zeeshan-mill> why you would want to i dont know :)
[00:07:59] <zeeshan-mill> even 260 rpm looks too fast
[00:08:10] <furrywolf> lots of cutting fluid.
[00:08:34] <zeeshan-mill> this is where an emulsion would be nice
[00:08:40] <zeeshan-mill> my next machine related purchase has to be a mister
[00:08:50] <furrywolf> 500rpm is still two seconds to tap each half inch deep hole.... :P
[00:10:10] <furrywolf> I do remember in one of the spindle encoder howtos that you're supposed to watch some variable and make sure it starts counting down when the spindle is reversed
[00:10:40] <zeeshan-mill> spindle-revs
[00:10:45] <zeeshan-mill> for me
[00:11:15] <zeeshan-mill> okay i think ive done enough testing today
[00:11:20] <zeeshan-mill> the yaxis is magically fixed
[00:11:25] <zeeshan-mill> musta been the connector
[00:11:33] <zeeshan-mill> gonna go upstairs :)
[00:17:24] <furrywolf> gah, that picture of the power supply makes me sad. I uploaded it in 2013. the assortment of stuff dangling off the workbench hasn't changed since then.
[00:17:33] <furrywolf> because I haven't done anything. :(
[00:18:09] <furrywolf> workbench is for useful projects, and instead all I do is work.
[00:18:10] <Just_pink> good night!
[00:19:19] <Just_pink> someone know about T slot sulotion?
[00:19:43] <furrywolf> T slot solution? Is that what you get when you dissolve t-slots in a suitable solvent?
[00:23:09] <zeeshan> thats a sexy power supply
[00:23:37] <zeeshan> i like your dangling resistor.
[00:23:37] <zeeshan> :)
[00:25:15] <Just_pink> furrywolf: almost..
[00:25:24] <furrywolf> heh. that resistor, and the multimeter, were for data logging some battery discharges. said meter, and batteries, are still sitting there...
[00:25:47] <Just_pink> I need to find the right T solt to dissolve
[00:27:10] <Just_pink> the 80 20 looks nice
[00:27:21] <Just_pink> but ineed just one T slot, not 4
[00:27:28] <Just_pink> I need *
[00:35:40] <furrywolf> I was testing some old NiFe cells.. had mixed luck. One set of 3, from the '40s, had two that tested at full capacity and one that sucked. Another set of 3 all tested at about 1/4 capacity. A set of 4 tested at about 1/10th capacity, but all I did was add water, even though they were bone dry...
[00:37:00] <furrywolf> they'd probably test a lot better if I added actual electrolyte, but they've been sitting on the workbench untouched for two years now apparantly. heh.
[00:40:08] <furrywolf> then I had several others, but they all leaked too badly to do any useful tests on.
[00:40:53] <furrywolf> I had another set of 4 with an internal connection issue, but needed to make a special tool to take them apart, which never got made.
[00:41:09] <renesis> i made salse verde for work party
[00:41:31] <furrywolf> was it nice and hot?
[00:41:32] <renesis> want to eat it all, cannot eat it
[00:41:40] <renesis> i did mild med and hot
[00:42:15] <renesis> mild had 80% of the peppers stripped of seeds, medium had 50% of the peppers with seeds stripped
[00:42:43] <furrywolf> what is your definition of hot? because hot when it comes to store-bought salsa is pretty much unnoticable...
[00:43:14] <renesis> one serrano pepper to one tamatillo is pretty hot
[00:43:23] <furrywolf> ah. so you made mild salsa.
[00:43:28] <renesis> as hot as anything youd get at a mex taco place
[00:43:38] <furrywolf> right. mild. :P
[00:43:47] <zeeshan> :p
[00:43:48] <renesis> right this is social salsa
[00:44:09] <furrywolf> a serrano is about, what, 10k shu? I have moruga scorpions at around 1m shu... :P
[00:44:26] <renesis> im not trying to kill everyone, 2 pepper to each tamatillo is nice but almost no one can deal with it
[00:44:45] <furrywolf> I wanted to get some carolina reapers this year, but the ebay seller took my money and ran.
[00:44:53] <furrywolf> because the planet is full of crooks.
[00:45:16] <renesis> i prefer it for tacos or eggs, but with chips to munch on for a couple hours, one to one is nice and most people still think its too spicy
[00:45:56] <furrywolf> I can't find hot salsa here. :(
[00:46:12] <renesis> it doesnt happen in markets
[00:46:26] <furrywolf> where I used to live, there were several local hot salsas... here none. there's one labeled "the hurt", which is hotter than the others available, but still not all that hot.
[00:46:49] <furrywolf> where I used to live, they had names like "hellfire" :)
[00:47:05] <furrywolf> which was a mixture of habaneros and carrots. quite good, actually.
[00:47:31] <furrywolf> one of the local burrito places has a "Death Paste", but it's just pureed habaneros, so only a medium.
[00:47:48] <renesis> i did a salsa naranja last summer with habaneros and these little orange cherry peppers
[00:47:57] <renesis> too sweet
[00:48:19] <furrywolf> I don't like the habanero taste... I usually prefer salsas made with other peppers. the carrot one I used to buy added a nice flavor to it.
[00:48:24] <renesis> er orange cherry tomatos
[00:48:50] <furrywolf> I don't even know what's alive in the greenhouse this year... I've been bedridden the last month and a lot of my starts died.
[00:48:52] <renesis> for red stuff i like cayenne
[00:49:24] <furrywolf> I still have scorpions, thai hot, ghost, aji crystal, serrano, manazano, and a couple others at least.
[00:49:33] <renesis> serrano and cayenne just have pepper taste, habanero and jalapeno are too sweet, they kind of dominate anything you put them into
[00:49:39] <renesis> jalapenos are kinda useless
[00:49:59] <furrywolf> jalapenos are good when you just want to add some flavor, not a lot of heat.
[00:50:08] <furrywolf> they're nice if you chop a few into an omlette or such.
[00:51:44] <furrywolf> I've had bad luck growing them... they take too long compared to most other peppers. I have a very short growing season here.
[00:52:06] <renesis> i guess once they get rip theyre bad quick, why they ship them green
[00:52:15] <furrywolf> Manzanos are the only peppers that really do well here, and then only in greenhouses. they'll sometimes live a couple years outdoors, but only if well-sheltered.
[00:53:35] <furrywolf> I highly suggest planting manzanos if you want pepper plants. They're not incredibly hot, but they grow really well.
[00:53:46] <furrywolf> they're pretty rare. I don't know why.
[00:54:17] <renesis> i dont have anyplace to grow stuff
[00:54:44] <renesis> i have a small patch of rocks near my front door
[00:55:43] <furrywolf> you're not one of those weird apartment dewllers are you
[00:55:44] <furrywolf> ?
[00:56:11] <furrywolf> my typing is degrading, must be past bedtime.
[00:56:13] <renesis> ya
[00:56:24] <Just_pink> someone know about stack light controller for this cute baby http://imgur.com/hxdGkgm
[00:56:33] <renesis> is cheap, close to school, dont have to deal with roommates
[00:57:46] <furrywolf> ... stack light controller? you mean like a couple transistors, or relays, or the high-current pins on a mesa board, or ssrs, or...?
[00:57:57] <Just_pink> It has red, yellow, green, buzzer and it use 24V
[00:58:03] <furrywolf> that it's a stack light is irrelevant. you're just turning some light bulbs on and off.
[00:58:24] <furrywolf> also, that looks waaay too much like it needs to have a high-power motor in the base and be covered in lube...
[00:58:57] <Just_pink> furrywolf: I mean to a cnontroller that alow you to make flashing and several beppeng options.
[00:59:08] <Just_pink> IP based
[00:59:09] <furrywolf> why not just do that from linuxcnc?
[00:59:44] <Just_pink> I want to do it right, not easy.
[00:59:58] <zeeshan> lol
[01:00:01] <Just_pink> or modbus based controller
[01:00:10] <zeeshan> furrywolf: why are you wasting your mind
[01:00:34] <furrywolf> ?
[01:00:52] <zeeshan> don't question mark me
[01:00:56] <renesis> not clear if because dildo reference or helping just_pink
[01:01:43] <renesis> i get in n out
[01:03:19] <furrywolf> Just_pink: so it sounds like you already know what you want, then.
[01:03:38] <furrywolf> I have no idea why you'd want to do that with a dedicated controller, rather than hal or classic ladder...
[01:04:13] <renesis> just_pink: microcontroller and electronics skills, probably arduino and some shields, a PLC, a PC with some sort of scripted realtime system (like linuxcnc)
[01:04:37] <renesis> you got options, k foods
[01:04:54] <Just_pink> I want to make virtual modbus addresses and each one will be one scenario, and the controller will send the right output to the stack light, like flashing the grenn light and make beeps
[01:05:53] <Just_pink> but arduino is not industrial stuff..
[01:06:07] <renesis> okay get PLCs
[01:06:30] <renesis> tell zeeshan to give you links for cheap ones
[01:07:08] <Just_pink> zeeshan: give me a link to cheap one
[01:07:13] <zeeshan> no
[01:07:22] <Just_pink> :(
[01:07:39] <Just_pink> but I'm cute and nice..
[01:07:55] <renesis> tits or gtfo
[01:08:17] * furrywolf is cute, nice, and FLUFFY!
[01:08:18] <Just_pink> and after I will buy it I will send a pic of it with pink nails...
[01:09:01] <Just_pink> zeeshan: so what do you say..
[01:09:23] <furrywolf> ... that has to be the stupidest conversation I've seen in a long time.
[01:10:06] <Just_pink> http://new.abb.com/plc
[01:10:08] <zeeshan> www.ebay.com plc
[01:10:09] <Just_pink> cuuuuute!!!!
[01:10:21] <renesis> guys my wireless trackbar was defeated by some sort of bagel garlic crumb
[01:10:27] <renesis> trackball
[01:11:03] <renesis> was stuck to the case by the antenna
[01:11:04] <Just_pink> renesis: try 21 century
[01:11:12] <zeeshan> renesis: haha
[01:11:15] <zeeshan> do you seriously use a trackball
[01:11:25] <renesis> thumb ball
[01:11:26] <furrywolf> I wish I had a trackball.
[01:11:35] <furrywolf> I had a laptop with one a long time ago, it was so much nicer than touchpads...
[01:11:41] <zeeshan> Just_pink: how much do you want to spend on a plc
[01:11:54] <renesis> the bigs ones are fun to play with, but theyre uncomfortable to use
[01:12:24] <Just_pink> zeeshan: I have now idea, I want something nice.. not junk
[01:12:25] <renesis> furrywolf: some keyboard clits are okay
[01:13:04] <Just_pink> just the wire duct + driving today cost me more than 200$
[01:13:53] <Just_pink> and the wiring going to cost me more than 700$
[01:14:17] <zeeshan> sounds like a waste of money
[01:14:26] <zeeshan> since you want to waste mooney
[01:14:31] <zeeshan> you could get the ac500 series by abb
[01:14:41] <zeeshan> or if you want to do the same thing for 1/5 the price
[01:14:46] <Just_pink> but I need 12AWG in 9 colors
[01:14:54] <Just_pink> 200 ft each.
[01:14:56] <zeeshan> you could use a micrologix 1000 series by rockwell
[01:14:58] <zeeshan> er
[01:15:02] <renesis> are you getting PVC or teflon?
[01:15:36] <Just_pink> PCV oil resistant
[01:15:44] <furrywolf> ... why would you need 12awg?
[01:15:47] <zeeshan> if you want top of the line PLC
[01:15:51] <zeeshan> you can get the mitusbishi q series
[01:16:02] <renesis> because its sexy why not!?
[01:16:09] <Just_pink> ans for the motor part some very flexi cable.
[01:16:29] <zeeshan> renesis: i didn't realize a g0704 needed a sexy plc
[01:16:31] <zeeshan> :)
[01:16:53] <Just_pink> renesis: I need also HMI
[01:17:09] <renesis> no the thick wire in 12 colors
[01:17:19] <renesis> but yeah the insulation, not so sexy
[01:18:05] <Just_pink> I start to do make some HMI with arduino.. but I think the machine deserve something better
[01:18:33] <zeeshan> renesis: insulation is ugly man
[01:18:39] <zeeshan> should just run bare copper wires
[01:18:40] <zeeshan> that's sexy
[01:18:59] <renesis> bus wire ftw
[01:19:30] <Just_pink> I can take a pic of the wire duct and the stuff
[01:19:31] <zeeshan> what is bus wire
[01:19:35] <renesis> except when you grab it thinking its solder and get confused because solder not working
[01:19:40] <renesis> its just wire
[01:19:55] <renesis> usually its tinned copper
[01:20:00] <zeeshan> http://www.hoodenergiasolar.com.br/wp-content/uploads/2014/09/solar_cell_bus_wire.jpg
[01:20:01] <zeeshan> wow
[01:20:03] <zeeshan> ive never seen tha tbefore
[01:20:22] <zeeshan> like ive seened the braided version of that
[01:20:26] <zeeshan> for ground strap
[01:20:27] <renesis> thats some ribbon stuff
[01:20:37] <zeeshan> but never llike ribbon
[01:21:04] <renesis> that looks thin, you can get tapes like that too
[01:21:58] <renesis> https://www.enasco.com/prod/images/products/77/AC098728l.jpg
[01:22:08] <renesis> awesome for power fixtures
[01:22:46] <Just_pink> Just wire ducts - http://i.imgur.com/920afmv.png
[01:22:57] <renesis> string a bunch of chassis mount power resistors together with it
[01:23:19] <renesis> guess that flat stuff is used for solar
[01:24:13] <Just_pink> I can almost buy 20X30 ebay cnc machine by the cost of just the wire duct..
[01:28:06] <Just_pink> ?
[01:28:31] <renesis> the bus wire images on google
[01:29:38] <Just_pink> renesis: what do you mean by "bus wire?"
[01:30:05] <renesis> zeeshan made a joke about insulation is stupid just use bare wire
[01:30:57] <renesis> i use bare wire at work for lots of prototype and fixture stuff, its usually silver tinned, called bus wire, comes in all the sizes
[01:31:38] <Just_pink> I have european standard bus bars that you cut to the length that you need and mount tham on special mount that go on the DIN rail
[01:32:18] <Just_pink> 5 meters of bus bars.... :)
[01:32:22] <renesis> yeah bars are neat for permanent stuff
[01:32:52] <furrywolf> bbl, wolfy bedtime
[01:33:01] <renesis> k nite
[01:33:13] <renesis> k burger fureal, bye
[01:33:30] <Just_pink> good night
[01:34:29] <Just_pink> how I'm programing the PLC?
[01:35:42] <Just_pink> renesis: zeeshan ?
[01:37:14] <Just_pink> what about this PLC?
[01:37:14] <Just_pink> http://www.ebay.com/itm/6ED1052-1FB00-0BA6-Siemens-LOGO-230RC-PLC-MODULE-115V-230V-RELAY-8-DI-4-DO/170986773754?_trksid=p2045573.c100034.m2102&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20131003150253%26meid%3Dff3afac8a8664dd19233d8058415c496%26pid%3D100034%26rk%3D1%26rkt%3D8%26mehot%3Dpp%26sd%3D221619422828
[01:38:07] <Just_pink> hi syyl
[01:38:19] <syyl> hoi
[01:39:31] <Just_pink> syyl: you know a bit about PLCs and MODBUS?
[01:39:37] <syyl> nope :)
[01:39:57] <Just_pink> syyl: so.. what bring you here?
[01:40:13] <syyl> just idling around ;)
[01:40:23] <Just_pink> mmm I see..
[01:40:36] <syyl> this is one of the few machinng related irc channels
[01:41:09] <Just_pink> I really need to finish with the control box (really big electrical panel)
[01:42:15] <Just_pink> Today I've also get a narrow wire duct for it.. and I'm also need a small T slot for the panel
[01:42:35] <Just_pink> syyl: Just wire ducts - http://i.imgur.com/920afmv.png
[01:43:51] <Just_pink> syyl: do you have a machine?
[01:44:08] <syyl> i had a cnc running on linuxcnc
[01:44:13] <syyl> *machine
[01:44:32] <syyl> http://gtwr.de/web/wp-content/uploads/2013/11/masch_deckel_g2nc.jpg
[01:44:33] <Just_pink> what kind?
[01:44:56] <Just_pink> WOW look really nice!
[01:45:00] <Just_pink> servo?
[01:45:07] <syyl> steppers and glas scales
[01:46:01] <Just_pink> I have just G0704
[01:46:16] <syyl> i sold the cnc :)
[01:46:23] <syyl> i replaced it with a manual machine
[01:46:35] <Just_pink> but I'm working on 4 by 3 foot electrical panel for it.
[01:46:43] <syyl> ah
[01:46:45] <Just_pink> syyl: why?!
[01:46:49] <syyl> the g0704 is supercommon here
[01:46:54] <syyl> its sold as "bf20"
[01:47:02] <syyl> i dont need cnc for my parts
[01:47:18] <syyl> and i already sit the whole day in front of a cnc machine at work
[01:47:28] <Just_pink> syyl: but I make the conversion really carzy..
[01:47:41] <syyl> https://dl.dropboxusercontent.com/u/24396704/IMG_8063.JPG
[01:47:59] <syyl> to get some cnc free time i bought on of those rf45 clones
[01:48:01] <Just_pink> HMI, MODBUS, a-looots of sensors, very big servos,,
[01:48:34] <Just_pink> the spindle motor look very big.
[01:48:49] <syyl> 3phase, 1.5kW
[01:49:42] <Just_pink> I live on the second floor
[01:50:09] <Just_pink> so.. I'm limited to 110V AC normal outlet,
[01:50:25] <syyl> your electric system is so messed up :D
[01:50:27] <syyl> 110V
[01:50:28] <Just_pink> and each of the servos is
[01:50:29] <syyl> man :D
[01:50:48] <syyl> here every house gets 3 phase/400V per default
[01:51:19] <Just_pink> the panel is build by the german standart.
[01:51:22] <Just_pink> 400V!
[01:51:24] <Just_pink> cool
[01:51:31] <syyl> between phases
[01:51:36] <syyl> 230 against ground
[01:52:03] <Just_pink> mm so it just 380..
[01:52:08] <Just_pink> you know AC..
[01:52:41] <Loetmichel> Just_pink: its 400V in europe now
[01:52:48] <syyl> 230*sqrt(3)
[01:53:07] <Just_pink> no 230 AC + 230 AC = 380V
[01:53:14] <syyl> no.
[01:53:17] <Loetmichel> they lowered the GB standard, and upped the .de and .fr standard to meet european harmonisation at 230/400V ;)
[01:53:22] <Just_pink> go to the panel with multimeter.
[01:54:07] <Loetmichel> no need to
[01:54:15] <Loetmichel> i measured that often enough
[01:54:32] <syyl> same here ;)
[01:54:36] <Just_pink> there is 120 offset between each phase.
[01:54:38] <Loetmichel> 230V single phase equals 400V between phases
[01:54:53] <Loetmichel> if three phase
[01:56:28] <Just_pink> I dont know why I remember 380..
[01:56:36] <Just_pink> maybe I'm wrong.
[01:58:36] <Just_pink> I know why
[01:59:20] <Just_pink> 380V Is the standart after 230V
[02:00:10] <Just_pink> and If you have 220V you wiil get 380V not 400
[02:01:39] <Just_pink> but I'm stuck with 110V :(
[02:03:11] <Just_pink> syyl: Loetmichel: what is the best option for HMI?
[02:04:29] <Just_pink> something that will be easy to program and show the temperature and send signals if the temperature go up in one of the sensors
[02:06:18] <Just_pink> all gone..
[02:11:34] <Just_pink> Akex_: hi
[02:12:01] <Akex_> Hi
[02:12:49] <Just_pink> you know about HMIs?
[02:14:06] <Akex_> Human machine interface ?
[02:14:34] <Just_pink> yes
[02:14:49] <Just_pink> I want something easy to program
[02:15:57] <Just_pink> to dispay the about 20-30 sensors output. and send error signal to the computer if something go wrong with the sensors.
[02:17:18] <Akex_> Yes ok and ? What do you want help ?
[02:20:01] <Just_pink> Do you know about a way to do it? or any recomended HMI?
[02:20:32] <Just_pink> Akex_: ?
[02:20:45] <Akex_> Yes i see
[02:21:02] <Akex_> I am not a pro, with linuxcnc
[02:21:38] <Akex_> Me i use a arduino for talk with linuxcnc, with serial usb
[02:21:57] <Just_pink> Akex_: there is no linuxcnc involved here pure hardware.
[02:22:03] <Akex_> I made a circuit prototype for tool change with arduino
[02:22:07] <Akex_> Haaa
[02:22:13] <Just_pink> Akex_: you use modbus?
[02:22:16] <Akex_> Ok sorry
[02:22:31] <Akex_> No mod bus just serial
[02:22:44] <Akex_> With ascii words
[02:23:07] <Just_pink> intresting.
[02:23:21] <Just_pink> What machine you have?
[02:24:08] <Just_pink> what type?
[02:24:41] <Akex_> A alexcnc
[02:24:46] <Akex_> XD
[02:25:15] <Akex_> 2 min i give you my you tube chanel , there are all my make
[02:25:37] <Just_pink> alexplace2001?
[02:25:50] <Akex_> Nop
[02:25:52] <Akex_> https://www.youtube.com/user/Schointss
[02:26:14] <Akex_> There are tool changer circuit and cnc and printer and allllll
[02:26:16] <Akex_> ;)
[02:26:32] <Just_pink> https://www.youtube.com/watch?v=anBsTg7qQ-Y
[02:26:36] <Just_pink> LOVE IT!
[02:26:55] <Just_pink> I need the same thing!!
[02:27:56] <Akex_> Is a hmi for octoprint printer
[02:28:12] <Akex_> Apache server php api
[02:28:36] <Just_pink> and how you make the 5" LCD?
[02:28:44] <Just_pink> what drive it?
[02:32:23] <Akex_> A for raspberry
[02:32:34] <Akex_> Is by gpio for this
[02:32:54] <Akex_> Is fbtft driver by notro
[02:33:13] <Just_pink> I have a RPI here
[02:33:18] <Just_pink> with rasbian
[02:33:34] <Just_pink> but I've vever work with the GPIO
[02:34:48] <Akex_> There a bigining of all Just_pink
[02:35:56] <Just_pink> I don't like the RPI It's not a reliable computer,
[02:36:08] <Akex_> Why ?
[02:36:13] <Akex_> You can
[02:36:17] <Akex_> With usb
[02:37:02] <Just_pink> show me one industrial machine that use usb to monitor critical sensors
[02:38:02] <Deejay> moin
[02:38:17] <Just_pink> morning
[02:39:00] <Just_pink> Deejay: what are you up to?
[02:41:02] <Deejay> ?
[02:42:39] <Just_pink> just try to make a starter for conversation with you...
[02:44:47] <Deejay> oh, sorry. how are you? going well?
[02:45:33] <Just_pink> yes.. slooow.. expensive.. but I have more cool parts at home..
[02:46:02] <Deejay> yeah
[02:46:13] <Just_pink> Today I've drive looog way to get narrow size wire duct as well.
[02:46:44] <Just_pink> and I get real satck light LED based, green yellow red + buzzer
[02:48:45] <Just_pink> now I need controler for the stack ligt, and find good place for wireing.
[02:49:55] <Just_pink> nobody want to speak with me :(
[02:50:27] <Akex_> Ro Just_pink
[02:50:46] <Just_pink> Ro?
[02:51:54] <Akex_> Ro don t worry be happy
[02:53:04] <Just_pink> I'm happy.. but I have parts for the machine all over the place,
[02:53:51] <Just_pink> this thing block the btroom door for example http://i.imgur.com/920afmv.png
[02:54:26] <Just_pink> bathroom *
[02:55:37] <Akex_> Loool
[02:55:52] <Akex_> And in your bedroom Just_pink ?
[02:56:26] <Just_pink> no.
[02:56:41] <Just_pink> I'm close to the machine..
[03:00:02] <Deejay> :)
[03:02:50] <Just_pink> BRB ice cream
[03:03:53] * Deejay also wants some ice cream
[03:09:58] <Just_pink> back
[03:10:09] <Just_pink> with some thing better
[03:12:04] <Just_pink> http://i.imgur.com/L0Wp2xQ.png
[03:12:44] <Just_pink> Deejay: ^
[03:13:10] <Just_pink> hi andypugh
[03:13:10] <Deejay> uuh
[03:13:36] <Just_pink> frozen Ice tea
[03:13:48] <Just_pink> I have 3 more..
[03:14:47] <Deejay> nice
[03:17:32] <Just_pink> I need to machine 2 more heat sinks..
[03:17:48] <Just_pink> but the controller is in parts...
[03:18:29] <Just_pink> and without the heat sinks I cant power it up :(
[03:36:18] <gonzo_> chicken and egg
[03:38:03] <Deejay> :)
[04:32:21] <Just_pink> everybody sleep...
[04:48:53] <vapula> Just_pink: depends where you are on the world, midday here
[04:55:05] <Just_pink> I'm in NY
[04:56:08] <XXCoder> new york
[04:56:14] <XXCoder> cool
[04:56:22] <XXCoder> 2:33 am here heh
[04:59:32] <Just_pink> XXCoder: where are you?
[04:59:50] <XXCoder> washington state
[04:59:52] <Deejay> 11:36 here
[04:59:56] <Deejay> am
[05:00:23] <vapula> ditto
[05:01:13] <Just_pink> here 5:38AM
[05:01:31] <XXCoder> cool
[05:01:32] <Just_pink> I need to go today to fastenal.
[05:01:35] <Deejay> Just_pink, why are you not asleep then?
[05:02:20] <Just_pink> I need to find a way to display 20-30 sensors
[05:02:43] <Just_pink> on reliable hardware
[05:02:45] <Deejay> ah, sleepless because of that problem? ;)
[05:04:39] <Just_pink> Deejay: you have to understand something. I have alllll over my home parts on parts for the CNC machine. now the problem is that I want everithing perfect, and this is why I'm stuck.
[05:05:23] <XXCoder> perfection is overrated
[05:05:38] <XXCoder> make a working cnc machine and you can make parts for it
[05:05:48] <Deejay> ah, i know these problems. i'm also perfectionist sometimes :)
[06:13:42] <CaptHindsight> Just_pink> I need to find a way to display 20-30 sensors
[06:14:01] <CaptHindsight> what types of sensors on what display?
[06:31:07] <CaptHindsight> http://www.comedi.org/index.html has drivers and some libs to get data from data acquisition boards and sensors, but there are no easy to use GUI maker tools
[06:39:03] <CaptHindsight> http://openscada.org/
[06:43:24] <CaptHindsight> http://www.opendax.org/ anyone ever use this?
[06:44:31] <CaptHindsight> http://www.enscada.com/a7khg9/IndigoSCADA.html
[07:38:42] <archivist_herron> someone did use openscada and linuxcnc at the same time iirc
[08:15:37] <CaptHindsight> I looked at it last year for laboratory automation
[08:17:11] <CaptHindsight> g-code is not ideal for controlling robots and synchronizing them with sensors and manipulators
[08:49:31] * SpeedEvil has 99 axes and cannot work out the end of the lyric.
[09:55:34] * jthornton is totally out of sync today, had to be at the customers at 7:30 for a meeting
[11:01:26] <zeeshan> quiet in here :P
[11:02:11] <CaptHindsight> _methods: https://www.indiegogo.com/projects/rocketbook-cloud-integrated-microwavable-notebook#/story microwave safe, in case you leave it or work in a microwave!
[11:05:06] <CaptHindsight> zeeshan: did you get your head straightened out? :)
[11:05:12] <zeeshan> haha
[11:05:13] <zeeshan> :D
[11:05:36] <zeeshan> ive isolated it to the gibs on the Y axis
[11:09:09] <CaptHindsight> https://www.indiegogo.com/projects/ergo-world-s-first-smart-standing-desk-that-talks#/story sounds like a sit-com, but it's not
[11:09:28] <_methods> wow so indie-gogo is like another kickstarter
[11:09:49] <CaptHindsight> a talking desk, I didn't know that i needed that
[11:10:02] <_methods> why do you need a microwaveable notebook?
[11:10:22] <CaptHindsight> after forcing myself to read through it...
[11:10:31] <malcom2073> _methods: Except the people running the projects get to keep the money, even if they don't make their goals
[11:10:38] <CaptHindsight> the ink disappears when heated
[11:10:51] <_methods> oooh magic buttons
[11:11:26] <_methods> oh the stretch goal is the ability to take pictures
[11:11:32] <_methods> i sure hope they can pull that off
[11:11:54] <_methods> pictures would be awesome
[11:12:04] <_methods> i'm so tired of painting things
[11:12:08] <CaptHindsight> sounds like a sketchy book to me
[11:12:13] <_methods> buwhahahaha
[11:12:18] <_methods> i see what you did there
[11:12:28] <malcom2073> _methods: Was it you that wanted info on the $90 touch probe?
[11:12:34] <_methods> no
[11:12:52] <malcom2073> Hmm, I'll read back through my logs then
[11:13:13] <_methods> i have paper
[11:13:20] <_methods> wtf i need a touch probe for
[11:13:27] <_methods> only n00bs need that crap
[11:13:49] <_methods> ermahgerd work offsets are sooooo complicated
[11:14:01] <_methods> i must need a probe to do it
[11:14:42] <_methods> edgefinder and paper
[11:14:55] <_methods> all i need
[11:15:10] <malcom2073> Yes... technology bad
[11:15:19] <_methods> technology is great
[11:15:19] <archivist> try that on 5 axes in space
[11:15:28] <zeeshan> touch probes are awesome
[11:15:54] <zeeshan> i guess methods never wants to trace a contour and store the point cloud
[11:15:59] <zeeshan> his loss :)
[11:16:10] <zeeshan> malcom2073: i'll take the link!
[11:16:11] <CaptHindsight> darn my slow fingers, I was trying to save you from being labeled a "probe hater"
[11:16:13] <_methods> it would be one thing if it was a real production machine all these probe people were working on
[11:16:16] <_methods> but they are not
[11:16:38] <archivist> why some kids need probes http://www.collection.archivist.info/searchv13.php?searchstr=bevel
[11:16:51] <_methods> i think some people just like to be probed
[11:16:56] <CaptHindsight> embrace the probe!
[11:17:12] <PetefromTn_> what'd I miss?
[11:17:28] <_methods> malcom2073 asked if i wanted some probe info
[11:17:30] <zeeshan> PetefromTn_: have you done g33.1 yet
[11:17:31] <_methods> and i said hell no
[11:17:37] <_methods> probes are bad mmmmk
[11:17:38] <archivist> my strain gauge arrived from china now I have to make my probe
[11:17:41] <PetefromTn_> rigid tap yeah why?
[11:17:45] <CaptHindsight> PetefromTn_: microwaveable sketchbook and probes
[11:17:47] <zeeshan> what what rpm
[11:17:53] <zeeshan> was fastest tapping youve done
[11:17:58] <zeeshan> *at
[11:18:02] <_methods> it's gettin friday cray cray up in here
[11:18:04] <PetefromTn_> I usually tap at like 3-400 RPM
[11:18:12] <Sync> what the hell
[11:18:20] <malcom2073> Ahh well can't find who wanted it
[11:18:26] <Sync> my rotary axis has the hirth coupling welded to the bellows coupler
[11:18:27] <malcom2073> zeeshan: http://www.wildhorse-innovations.com/index.php?_a=viewProd&productId=80
[11:18:33] <Sync> what a pain
[11:18:38] <_methods> maybe you'll have to do some more probing to get to the bottom of it
[11:18:39] <PetefromTn_> LOL MMmmmmk
[11:18:39] <_methods> lol
[11:18:57] <zeeshan> PetefromTn_: can you try doing M3 S600 ; G33.1 Z-xxxxxx K0.041666
[11:19:01] <zeeshan> when you get a chance
[11:19:04] <zeeshan> and see what your machine done?
[11:19:05] <zeeshan> *does
[11:19:08] <PetefromTn_> I hear those wild horse probes are okay but not terribly precise
[11:19:30] <PetefromTn_> why?
[11:19:35] <malcom2073> PetefromTn_: Thus far it's been as precise if not more so than the paper method
[11:19:45] <PetefromTn_> hehehe
[11:19:51] <zeeshan> mine reaches rotates to the target Z , reverses spindle
[11:19:52] <malcom2073> Which for $90, well worth the time saved :-D
[11:19:53] <zeeshan> and just sits there
[11:20:00] <zeeshan> with the spindle on lol
[11:20:06] <zeeshan> but upto 400 rpm im fine
[11:20:19] <zeeshan> just was worried why it's not faulting out
[11:20:24] <zeeshan> rather than just spinning there
[11:20:36] <zeeshan> i don't see anything weird in motion.spindle-revs
[11:20:37] <PetefromTn_> malcom2073 honestly I think for the price/accuracy it is a decnet probe
[11:20:49] <malcom2073> For sure it likely can't beat a $800 dealio heh
[11:20:53] <zeeshan> malcom2073: you own one?
[11:20:59] <malcom2073> zeeshan: My dad does
[11:21:04] <malcom2073> I'm gonna buy one once my mill gets up
[11:21:05] <PetefromTn_> well thats faster than I usually tap but I could try it I guess
[11:21:09] <zeeshan> have you done repeatability testing on it?
[11:21:15] <zeeshan> thats the only thing stopping me
[11:21:17] <Sync> just buy a crashed renishaw
[11:21:20] <zeeshan> apparently they're only good to 0.0005
[11:21:22] <Sync> they are mechanically robust
[11:21:23] <PetefromTn_> ^^
[11:21:32] <zeeshan> Sync: hard to find =/
[11:21:33] <malcom2073> Likely, but his machine is a knee mill, so no way to test it to that extreme
[11:21:46] <zeeshan> you can test it
[11:21:49] <zeeshan> by using an indicator
[11:21:53] <zeeshan> a tenths
[11:21:57] <zeeshan> attached to the axis
[11:22:18] <Sync> huh?
[11:22:22] <zeeshan> when the probe lights up, you should see zero on the indicator
[11:22:22] <Sync> they are everywhere
[11:22:28] <zeeshan> Sync: link
[11:22:29] <Sync> because they come out of crashed DMUs
[11:22:45] <Sync> look in your local machine scrap yard
[11:23:04] <malcom2073> Sync: not everyone lives within a couple hundred miles of one of those :-P
[11:23:22] <malcom2073> Or rather, one that allows picking
[11:23:24] <zeeshan> my machine scrap yard wants the same prices as new ones :)
[11:23:56] <PetefromTn_> I would love to get my hands on one for the VMC
[11:23:59] <Sync> got one of those for 30€ http://www.heidenhain.de/typo3temp/pics/TT140_K_l_de_web_dd55d0d3d9.jpg
[11:24:29] <Sync> but all the spindle probes were too large for my liking
[11:24:42] <zeeshan> cheapest one i see on ebay is 300$
[11:25:25] <PetefromTn_> I'll give you 35 LOL
[11:26:05] <PetefromTn_> thats the strain gauge type that will allow you to do diameter probing too it looks like SCORE!!
[11:26:17] <Sync> it is not a strain gauge
[11:26:24] <Sync> it is a classic 6 baller
[11:26:26] <PetefromTn_> oh no it looks like one
[11:26:34] <Sync> but it repeats within 2µm
[11:26:40] <PetefromTn_> SICK
[11:26:49] <Sync> they are doing some capacitive feedback to increase repeatability
[11:26:55] <PetefromTn_> if you happen across anymore lemme know ;)
[11:27:29] <zeeshan> me too!
[11:27:30] <zeeshan> :[
[11:27:38] <zeeshan> http://i.ebayimg.com/00/s/NjAwWDgwMA==/z/7FAAAOSwpDdVeFJD/$_27.JPG
[11:27:47] <zeeshan> what tool holders do you guys see here
[11:27:52] <Sync> at first I gotta figure out the lehmann
[11:27:54] <zeeshan> i see an integrated face milkl
[11:28:02] <zeeshan> a couple of end mill holders
[11:28:06] <zeeshan> im not sure what the top 2 are
[11:29:27] <PetefromTn_> one looks like a stub length endmill holder I think
[11:29:41] <PetefromTn_> the other may be a shrink fit or something
[11:29:51] <zeeshan> ah
[11:29:52] <Sync> the horizontzal one might be hydraulic
[11:30:14] <PetefromTn_> buy em and let me have the facemill I need one LOL
[11:30:26] <zeeshan> i mainly need the pull studs
[11:30:34] <zeeshan> this style pull stud are hard to find :(
[11:30:35] <PetefromTn_> even better
[11:31:00] <Sync> can't you just turn your own?
[11:31:05] <zeeshan> i can
[11:31:09] <zeeshan> but you gotta heat treat em
[11:31:12] <zeeshan> and do all this bs to em
[11:31:19] <Sync> you can just use them as they are
[11:31:22] <PetefromTn_> I would not bother turning them
[11:31:29] <zeeshan> i have them modelled
[11:31:33] <jdh> print them
[11:31:36] <Sync> use prehard toolsteel
[11:31:38] <PetefromTn_> ROFL
[11:31:41] <zeeshan> haha
[11:31:48] <Sync> 30HRC and they will last acceptably long
[11:31:53] <jdh> it's the future
[11:31:53] <zeeshan> maritool sells em
[11:31:57] <zeeshan> they are 50 HRc
[11:32:01] <zeeshan> but also 20bux each
[11:32:28] <Sync> for 20/each I'd just buy them
[11:32:35] <Sync> not worth my time dicking around
[11:32:37] <PetefromTn_> thats reasonable
[11:32:50] <zeeshan> well it gets really expensive when you need 20
[11:32:50] <zeeshan> :)
[11:32:53] <PetefromTn_> I lucked out
[11:32:54] <Sync> but if you are a cheapskate use toolsteel and turn them
[11:33:00] <PetefromTn_> my machine came with a box full of them
[11:33:03] <Sync> your time is also expensive
[11:33:08] <zeeshan> i bought some on ebay a while back
[11:33:19] <zeeshan> got like 20 for $40 + shipping
[11:33:19] <PetefromTn_> machine something for your buddies for sale and just buy em
[11:33:35] <zeeshan> i don't need them urgently though!
[11:33:38] <PetefromTn_> or offer to machine something for them IF they buy them for you....
[11:33:55] <PetefromTn_> done stuff like that before everybody wins...
[11:34:02] <zeeshan> barter :D
[11:34:19] <PetefromTn_> yeah man like the cavemen of old
[11:34:44] <PetefromTn_> I would not have half the stuff I do without bartering it seems LOL
[11:34:47] <Sync> or convert the machine to some easier to get pullstud
[11:34:54] <Sync> that thing seems to be awfully involved
[11:37:20] <PetefromTn_> well more rolling to do today on the CNC lathe LOL
[11:38:00] <PetefromTn_> what I did yesterday came out pretty good I was surprised but I will need more of those tiny rollers for the tight areas.
[11:42:19] <CaptHindsight> "your time is also expensive" I think many on IRC would disagree with this :)
[11:43:06] <t12> lol
[11:43:22] <PetefromTn_> I used to think meh I got time to do it myself. Nowadays I realize that I needed to spend that time drumming up work or making parts not screwing with machines...
[11:43:47] <t12> i have mixed feelings about time optimization
[11:43:59] <t12> at some point it just becomes a weird sort of greed
[11:44:05] <PetefromTn_> but honestly if I did not do it myself and retrofit these machines I have I would not have them
[11:44:05] <t12> but not enough and life disappears too quick
[11:44:24] <PetefromTn_> so it is a two edges sword
[11:45:22] <jdh> sleep less!
[11:45:59] <PetefromTn_> I do love to sleep ;)
[11:46:17] <CaptHindsight> t12: how goes the DNA fab sale?
[11:46:21] <PetefromTn_> I am a night person tho and often when most people are sleeping I am out in the shop working...
[11:46:29] <Sync> CaptHindsight: well, for me there is a tradeoff between saving money and wasting time not finisning a project
[11:47:00] <Sync> lets say if I can spend a k to get something done instantly instead of dicking around for weeks, I'll most likely do it
[11:47:22] <t12> eh
[11:47:30] <t12> not much luck at finding a whole buyer
[11:47:41] <t12> liquidation value came in suprisingly low, but they could just be estimating it badly
[11:48:08] <t12> still trying to figure out how to take control of the thing instead of burning it down
[11:50:58] <CaptHindsight> i was looking over way to do it faster and less expensively but it looks like another patent minefield
[11:51:48] <Sync> don't look at patents then
[11:53:42] <CaptHindsight> another tech where China will take over unless the Trans Pacific Partnership is being tailored to cripple things like that
[11:54:39] <CaptHindsight> low cost meds from Thailand and Philippines, China ignoring western patents etc
[11:55:09] <PetefromTn_> they basically ignore everything
[11:55:47] <CaptHindsight> good thing or Walmart wouldn't be in business
[11:56:23] <PetefromTn_> that's a good thing?
[11:57:00] <jdh> largest employer in .us
[11:57:34] <PetefromTn_> you wanna work there?
[11:58:03] <jdh> nope. the people that work there do
[11:58:43] <PetefromTn_> https://www.facebook.com/u2/videos/10154088474306686/ This is awesome...
[11:58:45] <CaptHindsight> where else are the elderly, disabled and newly out of college supposed to work?
[11:59:09] <PetefromTn_> probably in any of the mom and pop businesses that would still be here were it NOT for WalMart
[12:00:08] <CaptHindsight> oh, you thought I was serious
[12:01:01] <PetefromTn_> well reading back thru perhaps I was pretty dense for not seeing it as you were laying it on pretty thick ;)
[12:01:39] <Tom_itx> zeeshan, when you get a chance could you try M3 2000; G33.1 Z-xxxxxx K0.041666? mine doesn't seem to want to stop quick enough
[12:02:30] <PetefromTn_> LOL
[12:02:34] <Tom_itx> :D
[12:03:48] <Tom_itx> i think you can get away with alot more with those reversing tapping heads...
[12:08:21] <PetefromTn_> snap snap snappin' da taps!!
[12:14:28] <zeeshan> Tom_itx: wut
[12:14:40] <zeeshan> Tom_itx: well thats what i noticed
[12:14:42] <zeeshan> it overshoots
[12:14:54] <zeeshan> so youre saying its something to do w/ how long it takes the motor to decelerate?
[12:15:06] <zeeshan> is there a variable to adjust the deceleration time in linuxcnc
[12:15:12] <zeeshan> to give it an idea how long it takes the spindle to reverse
[12:15:50] <cradek> no, you have to use slower spindle speed or reduce the commanded tapping depth
[12:15:51] <Tom_itx> add a brake
[12:16:02] <furrywolf> argh. how can the health care system be so entirely fucking broken? I can't see a doctor.
[12:16:06] <Tom_itx> and use slower S words
[12:16:15] <furrywolf> everywhere I go says the waiting list for new patients is measured in months.
[12:16:17] <zeeshan> cradek see i dont care about tapping at high speeds
[12:16:19] <cradek> yes consider adding a braking resistor to your vfd and adjusting the vfd accordingly
[12:16:26] <zeeshan> for me im just worried why the machine didn't ferror out
[12:16:40] <zeeshan> it literally went down to the Z height in g33.1 , overshot
[12:16:42] <furrywolf> and half of them want payment up front, which means I can't bill it to the stupid bitch's car insurance.
[12:16:42] <zeeshan> reversed spindle
[12:16:45] <zeeshan> and it just stayed there..
[12:16:46] <furrywolf> apparantly there's also only one working MRI machine and one doctor who knows how to use it, and the wait for that is over a month too, after you wait the month+ to even be seen by a doctor to be referred for an MRI.
[12:16:48] <cradek> it's normal to go past the commanded point when tapping
[12:16:50] <zeeshan> while the spindle was running
[12:16:54] <cradek> wait
[12:17:02] <zeeshan> which means if i was actually tapping something, i woulda snapped the tap
[12:17:18] <zeeshan> at low speeds it works fine, but i want it to error out if this same situation occurs
[12:17:36] <furrywolf> cradek: his spindle sat there, running at full speed, without the synchronized motion that should have occoured. my first guess was his quadrature encoder has something off, and linuxcnc didn't know which way it was turning.
[12:17:38] <Tom_itx> tap at slower speeds
[12:17:52] <cradek> yeah it seems like something is misconfigured
[12:17:58] <zeeshan> Tom_itx: that doesn't fix the problem i experienced
[12:18:41] <zeeshan> i don't see anything odd in motion.spindle-revs either
[12:18:43] <cradek> I think if the spindle doesn't reverse in some huge number of turns (ten??) motion will stop
[12:19:04] <furrywolf> however, even if that is the case, the spindle turning the opposite way than commanded should generate an error.
[12:19:10] <cradek> if so, you need to get it to reverse sooner than that
[12:19:16] <zeeshan> yes but why doesnt it error out
[12:19:19] <zeeshan> and turn off everything
[12:19:21] <zeeshan> why does it continue spinning?
[12:19:31] <cradek> that might be a bug
[12:19:39] <cradek> either way it will break the tap off
[12:19:42] <zeeshan> haha
[12:19:53] <cradek> there's no way NOT to break the tap off, if the spindle doesn't reverse when you tell it to
[12:20:01] <furrywolf> have you checked your encoder output to make sure that your encoder is still generating proper signals while the spindle is reversed?
[12:20:09] <zeeshan> furrywolf: yes its fine
[12:20:15] <zeeshan> im pretty sure cradek is on the money
[12:20:20] <CaptHindsight> unless tapping butter or cheese
[12:20:22] <zeeshan> that it's to do with the the spindle not reversing fast enough
[12:20:25] <cradek> tc.target = line_xyz.tmag + 10. * tp->uu_per_rev;
[12:20:31] <cradek> // allow 10 turns of the spindle to stop - we don't want to just go on forever
[12:20:38] <cradek> yeah, it's 10 turns
[12:20:59] <furrywolf> then after ten turns it should generate an error and stop...
[12:21:28] <Tom_itx> does the index signal get reset during those 10 turns?
[12:21:37] <cradek> yes it'd be nice to say "your spindle didn't reverse within 10 turns; sorry about your tap"
[12:21:38] <Tom_itx> or does it error out
[12:21:53] <zeeshan> cradek: the tap wouldn't break though
[12:21:55] <zeeshan> if it was a blind hold yes
[12:21:58] <cradek> oh yes it would
[12:22:09] <zeeshan> but thru hole, it'd be slowing down
[12:22:13] <zeeshan> while Z is still feeding
[12:22:34] <furrywolf> Tom_itx: nothing should be reset, as the backing out needs to be on the same path or you break the tap or re-cut the threads.
[12:22:35] <cradek> and then you have a tap rigidly attached to a vmc's spindle and embedded deep in the part
[12:22:46] <cradek> it'll break soon if it hasn't already :-)
[12:23:16] <zeeshan> i really think it should kill the spindle
[12:23:18] <cradek> if the spindle doesn't reverse when commanded it also might not stop when commanded
[12:23:18] <zeeshan> asap that error detects
[12:23:19] <Tom_itx> furrywolf, the index pin is a bidirectional signal
[12:23:20] <zeeshan> even if the tap breaks
[12:23:40] <cradek> stopping the forward motion is the important part
[12:23:42] <Tom_itx> reset by hm2 every turn
[12:24:05] <furrywolf> agreed. any detection of a failure like that should result in everything stopping, not leaving the machine running...
[12:24:07] <cradek> I'd happily review a patch that generates a better error in this situation
[12:24:19] <zeeshan> im not complaining cradek
[12:24:20] <zeeshan> just worried :)
[12:24:45] <furrywolf> cradek: here's a spindle reversing question for you: can linuxcnc be made to pause and let me manually reverse the spindle in the middle of a tap operation?
[12:24:45] <cradek> to make it foolproof you should configure your spindle to not go so fast it can't reverse in 10 turns maybe?
[12:24:59] <zeeshan> cradek yes that is the goal for me now
[12:25:00] <cradek> furrywolf: nope
[12:25:11] <Tom_itx> 10 turns on a tap is quite a bit of error margin
[12:25:16] <cradek> Tom_itx: yeah
[12:25:18] <zeeshan> i was just worried it'd randomly happen at 200 rpm too
[12:25:21] <zeeshan> but you've explained it wont
[12:25:27] <cradek> add vfd braking!
[12:25:29] <zeeshan> since it's to do w/ spindle slow slowing
[12:25:37] <zeeshan> and one thing to notice is it'd slow down even faster when actually tapping
[12:25:39] <zeeshan> and not flying in the air
[12:25:42] <zeeshan> cause there is more resistance
[12:26:54] <furrywolf> I don't plan on doing enough tapping to want to replace my two perfectly good manual spindle reverse switches with electrical controls, but it'd need to turn off the spindle, pause, then I'd flip the switch and un-pause, then turn the spindle back on and back out of the hole, turn off spindle, pause, I'd flip it back to forwards, hit unpause, it'd turn the spindle back on...
[12:27:24] <PetefromTn_> kinda surprised your spindle takes that long to reverse isn't it a slower max speed and gear driven?
[12:27:47] <zeeshan> PetefromTn_: im in 1:1 gear
[12:27:48] <PetefromTn_> oh and I laughed out loud to some of Cradek's comments
[12:28:34] <zeeshan> http://c2.staticflickr.com/8/7480/16082519967_8e2e4ad967_h.jpg
[12:28:40] * zeeshan doesn't see room for a braking resistor :(
[12:29:00] <Tom_itx> alot of controls put them on top
[12:29:07] <Tom_itx> in a cage
[12:29:08] <zeeshan> outside the enclosure?
[12:29:10] <PetefromTn_> my braking resistor is OUTSIDE the electronics cabinet
[12:29:28] <PetefromTn_> you don't want it in there anyways generating tons of heat for you trons
[12:29:38] <Tom_itx> why would you want all that heat inside your enclosure?
[12:29:48] <zeeshan> to keep it cozy?
[12:29:49] <zeeshan> why else
[12:30:05] <zeeshan> https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcToRoLhXldN6aOhtr_KkmZa8sZ4OulAG4TpwSmCLNJccLeK69X1
[12:30:08] <Tom_itx> mount it to your chair to keep your butt warm in the winter
[12:30:12] <zeeshan> this is what the braking resistors almost look like
[12:30:15] <zeeshan> as an option for my vfd
[12:30:23] <PetefromTn_> I tucked mine between the column and the enclosure where there is like a four inch gap to keep people from reaching in there and grabbing hold of the hot damn thing.
[12:30:27] <zeeshan> so i guess they need an enclosure
[12:30:54] <Tom_itx> stove elements work too
[12:31:46] <PetefromTn_> yeah that is what I am using...
[12:32:40] <furrywolf> hrmm. can I brake a single-phase induction motor? I've never tried. lol
[12:32:59] <PetefromTn_> sure I have broken plenty ;)
[12:33:00] <pcw_home> apply DC
[12:33:49] <furrywolf> I really don't want to invest much effort into controls for my motors... single-phase capacitor-start motors are always going to suck.
[12:34:37] <PetefromTn_> get a 3 phase and VFD and be done with it... or get a bigass DC motor and controller like I did.
[12:35:04] <furrywolf> but it's a shoptask. it's not worth buying expensive parts for.
[12:35:09] <furrywolf> and I'd need two motors.
[12:35:15] <furrywolf> and it'll still suck! heh
[12:35:29] <PetefromTn_> that was ON my shoptask
[12:36:02] <PetefromTn_> I used the motor and controller board from a big treadmill
[12:36:58] <furrywolf> lol
[12:37:24] <PetefromTn_> laugh if you want but it worked really good...
[12:37:26] <furrywolf> I just don't feel the machine is worth putting that much money (or, in the case of trying to recycle treadmill parts, time) into.
[12:37:31] <PetefromTn_> plus infinitely variable speed
[12:37:57] <PetefromTn_> if it is not worth that then WTF are you doing talking about CNC retrofitting it?
[12:38:06] <zeeshan> relax
[12:38:07] <zeeshan> both of you
[12:38:12] <zeeshan> go to your corners
[12:38:14] <zeeshan> :-)
[12:38:28] <pcw_home> Fight! Fight! Fight!
[12:38:35] <PetefromTn_> BIG GRIN
[12:39:04] <furrywolf> hrmm, looking on ebay, there's no 120V 3-phase motors, so I'd need to boost it to 230 before driving the VFD, needing a big transformer too...
[12:39:40] <zeeshan> no
[12:39:47] <Tom_itx> treadmill controls don't have reverse do they
[12:39:51] <PetefromTn_> that is why a DC motor and controller would work
[12:39:59] <zeeshan> if its a 1hp motor or less
[12:40:00] <PetefromTn_> sure they do
[12:40:05] <zeeshan> there exists 110V input
[12:40:08] <zeeshan> and 230V 3 phase output drives.
[12:40:12] <zeeshan> for like $150
[12:40:39] <zeeshan> http://www.factorymation.com/Products/FM50_115V/FM50-101-C.html
[12:40:40] <zeeshan> nm
[12:40:41] <zeeshan> 130
[12:40:41] <furrywolf> in any case, the mill project is mostly cancelled... I just figured it was a good time to ask about the spindle reverse since people were already thinking about spindle reverse.
[12:40:53] <furrywolf> I spent the morning trying to find a doctor, and failed.
[12:40:53] <PetefromTn_> one nice thing about the treadmill motor is they spin really fast and with some pullies/gearing you can get some good power from them
[12:42:42] <furrywolf> right now I can't even move the mill out to work on it, much less work on it, or use it.
[12:43:33] <JT-Shop> potassium pickle time
[12:43:52] <PetefromTn_> ?
[12:45:48] <furrywolf> I'm not sure what to do... even if I see a doctor, I don't know if they'd be able to do anything... if it's a problem that doesn't need surgery, I'm stuck with it, and if it does need surgery, I can't afford it, and it would take a year to heal anyway... I can't work... playing with CNC is not happening any time soon it seems.
[12:46:59] <SpeedEvil> furrywolf: Come to the UK, marry me, free NHS. (not really)
[12:47:19] <SpeedEvil> Actually - I don't know the rules in that situation.
[12:47:25] <furrywolf> but, I couldn't find a doctor that would see me in the next month anyway. the supposedly open-door place said THREE MONTHS.
[12:47:26] <pcw_home> Dam gopher got our best a squash plant :-(
[12:47:28] * furrywolf doesn't like men...
[12:47:30] <SpeedEvil> I am damn glad I don't have to pay for it.
[12:47:38] <malcom2073> Wasn't that an adam sandler movie?
[12:48:07] <malcom2073> furrywolf: one of the joys of everyone suddenly being forced to have insurance: doctors offices are overwhelmed
[12:48:09] <SpeedEvil> furry - yes - hence the (not really) - otherwise I'd have been totally serious.
[12:48:37] <SpeedEvil> It would be nice if MRI machines were a little easier to make
[12:48:38] <furrywolf> malcom2073: and I don't have insurance. too expensive.
[12:48:43] <SpeedEvil> CT machines are damn easy
[12:48:48] <SpeedEvil> But - carcinogenic
[12:49:44] * SpeedEvil quacks.
[12:50:10] <JT-Shop> banana
[12:51:05] <CaptHindsight> SpeedEvil: there's no simple DIY MRI kit anywhere?
[12:51:05] <PetefromTn_> aah
[12:51:14] <SpeedEvil> CaptHindsight: Well - there is.
[12:51:24] <SpeedEvil> CaptHindsight: the problem is it's several pixel level.
[12:51:24] <PetefromTn_> we need a linuxCNC MRI machine build
[12:51:26] <PetefromTn_> !!
[12:51:49] <PetefromTn_> point cloud of your internal organs/
[12:51:49] <SpeedEvil> And to the point where you can if you put your hand in the MRI machine, you can tell if it's a left or a right hand in about an hour
[12:52:27] <SpeedEvil> To get clinically actually useful MRI, you do not quite absolutely have to have superconductors.
[12:52:28] <PetefromTn_> take it into solidworks and be able to create surfaces
[12:52:47] <PetefromTn_> :D
[12:52:50] <SpeedEvil> The problem is basically that MRI has no signal unless you have voxels made of one thing.
[12:53:01] <SpeedEvil> So a mixed flesh/bone voxel drops out
[12:53:28] <SpeedEvil> Which means you need quite high resolution to be able to pick up even centimeter sized bits of tissue
[12:53:59] <archivist> and lots of software
[12:54:18] <SpeedEvil> Software is tractable
[12:54:38] <SpeedEvil> Your signal basically pops out as n fourier transforms
[12:54:52] <SpeedEvil> which you make into one picture of a slice
[12:55:13] <SpeedEvil> (n='x' pixels. 'y' ones pop out in frequency/phase space)
[12:56:11] <SpeedEvil> It's mathetically beautiful
[12:56:37] <JT-Shop> crap, just broke the screw on my 1/4" round insert holder
[12:56:50] <SpeedEvil> :/
[12:57:23] <archivist> diamond burr, dremel and a microscope
[12:57:59] <furrywolf> bbl
[12:58:14] <archivist> or wander to the nearest owner of an edm to get it blasted out
[12:58:21] <JT-Shop> I have all but one of those items
[12:59:03] <archivist> I dont have the edm but there is a local shop :)
[12:59:21] <archivist> cost me a tenner last time
[13:00:10] <PetefromTn_> I got the diamond burr, High speed pencil grinder, AND a microscope...no EDM tho sadly
[13:04:05] <archivist> a cheeeeeep one http://mikesworkshop.weebly.com/a-spark-erosion-apparatus.html?sa=X&ved=0CDYQ9QEwEGoVChMI0Yvc4qf0xgIVRZ3bCh1cOQF3
[13:04:44] <archivist> better ones use a small micro and a stepper
[13:06:44] <PetefromTn_> surely there is some way to convert a Tig welder to do that...
[13:06:48] <JT-Shop> I might get lucky the screw hole goes all the way through
[13:07:37] <archivist> tig probably has far too much current for erosion work
[13:08:19] <PetefromTn_> I typically just machine them out with a carbide endmill going SLOW
[13:13:11] <JT-Shop> not having a 1/16" carbide end mill on hand that's not an option on this one
[13:15:51] <JT-Shop> and I had to cut it down to 1/2 sq from 3/4 sq shank
[13:19:11] <PetefromTn_> damn
[13:20:00] <PetefromTn_> there are a couple local shop with sinkers that could fix that here but I have never done it.
[13:21:21] <JT-Shop> it's such a tiny screw
[13:21:37] <PetefromTn_> oh I thought it was a broken tap?
[13:21:52] <JT-Shop> 1/4" round insert screw
[13:22:13] <PetefromTn_> in a toolholder?
[13:22:25] <JT-Shop> I might be able to take a 1/8" carbide EM and mill a bit from the back
[13:22:26] <JT-Shop> yea
[13:22:52] <PetefromTn_> those are hard little bastards...
[13:23:46] <JT-Shop> if I can just get it to start coming out I'm golden
[13:25:06] <archivist> punch, hammer inwards avoiding the holder at all costs, this would indent the hss bit a little and loosen the screw a little
[13:26:50] <archivist> I got a lot better with a hammer and punches during my period of living off scrap metal separation
[13:29:55] * FinboySlick pictured archivist actually 'charging' himself by placing himself between different pieces of scrap metal and consuming galvanic currents.
[13:31:35] <archivist> separating the steel from bronze, aluminium and whatever, hard on your hands though
[13:34:12] <FinboySlick> Well, yeah. But the steampunk android imagery was a bit more badass.
[13:38:58] <FinboySlick> I was reading about that DIY sinker spark erosion setup. Kerosene as a dielectric sounds dangerous to me.
[13:39:26] <Sync> why?
[13:39:35] <Sync> use diesel
[13:39:43] <Sync> it is not going to burn
[13:40:05] <FinboySlick> I know it's hard to ignite but it does burn.
[13:40:18] <archivist> the sparks are under the surface no possibility of flame
[13:41:19] <malcom2073> It's like welding a diesel tank: You have to fill it up and weld under liquid heh
[13:41:22] <archivist> unless you silly and run the vat/enclosure dry
[13:43:12] <PetefromTn_> yeah don't be silly ;)
[14:05:00] <JT-Shop> got it out!
[14:15:18] <PetefromTn_> SWEET!
[14:16:30] <archivist> with or without finger damage :)
[14:26:54] <jthornton> only one minor cut :)
[14:27:33] <archivist> I managed 5 tiny cuts today messing with glass
[14:29:22] <skunkworks> we went to the county fair. no cuts.
[14:41:02] <Tom_itx> JT-Shop, never doubted a bit
[15:09:43] <andypugh> archivist: What were you doing with glass?
[15:23:53] <CaptHindsight> andypugh: just wondering if you ever got around to working with the UDOO and your impression of it
[15:24:51] <andypugh> I never got an RTAI kernel running, and LinuxCNC abandoned Xenomai, so I rather lost interest.
[15:27:46] <CaptHindsight> we sorted out all the magic from the tool chains for ARM so I was going to look at imx6 again when I have time
[15:32:52] <CaptHindsight> any news from Tormach after the founded passed away?
[15:34:11] <CaptHindsight> https://www.tormach.com/blog/greg-jackson-1952-2015/comment-page-1/
[15:38:07] <cradek> CaptHindsight: a little. it sounds like they will be ok.
[15:47:54] <zeeshan-laptop> another late night in the lab
[16:01:25] <XXCoder> zeeshan-laptop: so, trying to take over world as usual eh heh
[16:01:30] <XXCoder> loved that show
[16:01:40] <zeeshan-laptop> mad scientist
[16:01:49] <XXCoder> no
[16:01:49] <zeeshan-laptop> unfortuantely im doing some really boring tests
[16:04:33] <zeeshan-laptop> i didnt get your reference :{
[16:05:47] <skunksleep> Pinkey and the brain..
[16:05:49] <PetefromTn_> same thing we do everyday Pinky.....TRY TO TAKE OVER THE WORLD!!
[16:07:43] <XXCoder> yeah pinky and brain
[16:23:40] <Deejay> gn8
[16:23:42] <Aero-Tec> anyone building a cnc plasma table?
[16:23:48] <Aero-Tec> need a good THC
[16:24:35] <Aero-Tec> non contact one would be great
[16:25:06] <zeeshan-laptop> whos pinky and brain
[16:25:19] <Aero-Tec> it a cartoon
[16:25:25] <zeeshan-laptop> i never watched cartoons growing up :{
[16:25:51] <zeeshan-laptop> i grew up watching CARS!!
[16:25:51] <XXCoder> too bad, why though. never too late though lol
[16:26:05] <zeeshan-laptop> i watched dumb crap as a kid
[16:26:07] <zeeshan-laptop> like wwf
[16:26:08] <zeeshan-laptop> haha
[16:26:16] <XXCoder> that is totally real lol
[16:26:19] <Aero-Tec> not sure how old you are but you would have to be young to have watched it growing up
[16:26:33] <zeeshan-laptop> 30
[16:27:08] <Aero-Tec> I would guess it was not running yet
[16:27:17] <Aero-Tec> not sure how old it is
[16:27:41] <Aero-Tec> anyway
[16:27:48] <Aero-Tec> THC for plasma
[16:28:07] <PetefromTn_> I watched it and I am 45
[16:28:12] <Aero-Tec> looking for a good but not to expensive one
[16:28:32] <Aero-Tec> you watched it when you were a kid?
[16:29:03] <PetefromTn_> I watched it when It came out...don't remember when
[16:29:04] <Aero-Tec> thought it was not that old
[16:29:18] <PetefromTn_> it was actually pretty funny
[16:29:28] <zeeshan-laptop> mesa thc
[16:29:30] <PetefromTn_> don't think it lasted very long tho
[16:29:38] <Aero-Tec> the few times I did see it it was ok
[16:33:08] <Aero-Tec> looked on the mesa site
[16:33:14] <Aero-Tec> could not find THC
[16:33:30] <Aero-Tec> they should have a search option
[16:34:36] <zeeshan-laptop> http://store.mesanet.com/index.php?route=product/product&product_id=128
[16:34:39] <Aero-Tec> phoning them
[16:39:26] <Aero-Tec> need to email them
[16:40:09] <Aero-Tec> nice gal but she did not know anything other then to email support
[16:40:31] <Aero-Tec> I clicked the link
[16:50:49] <zeeshan-laptop> speak to pcw :)
[18:00:46] <Loetmichel2> *huiiii* here is a bit of a "storm" going on... just saw our monoblock PVC garden char fly across the balcony.. and the lightning frequency is about 5 per minute ;)
[18:01:51] <zeeshan-laptop> high altitude lightning
[18:01:55] <zeeshan-laptop> or actually touching the ground
[18:02:02] <zeeshan-laptop> i love the high altitude lightning show
[18:02:04] <XXCoder> Loetmichel2: build a way to use those power
[18:02:56] <furrywolf> http://humboldt.craigslist.org/tls/5138692718.html if only I had money. :(
[18:03:53] <XXCoder> one of most comment sentences start with "if only..."
[18:17:17] <furrywolf> how much do you figure that turning center is worth?
[18:20:06] <PCW> ~500 scrap
[18:20:59] <furrywolf> aww. not worth trying to get, then?
[18:22:20] <malcom2073> sealed bid auctions are lame
[18:22:25] <PCW> Might be, wonder what vintage it is
[18:23:28] <Tom_itx> Mori are pretty rugged unless they drove it into the dirt
[18:24:21] <Tom_itx> being a College, it probably had light work but many crashes
[18:27:51] <andypugh> Bid a silly number that you don’t mind losing. You might be the only one. It looks pretty clean, so perhaps bid scrap + what you don’t mind losing :-)
[18:28:24] <Tom_itx> it would cost the scrap value to have it moved
[18:28:28] <Tom_itx> at least
[18:28:38] <andypugh> If someone bids more, there is some confort in the thought that is is going to someone who wants it
[18:28:53] <XXCoder> sometimes I use Mori machine at work but newer version definitely. its OS/2 os keeps crashing lately though.
[18:29:06] <andypugh> Depends where it is and what it weighs.
[18:29:48] <andypugh> Under 2 tons you can move things on a pallet truck, and those are cheap.
[18:30:05] <furrywolf> the owner of the local scrapyard shows up and bids at every auction. nothing ever sells for less than scrap. in a normal auction, she normally won't bid against me unless my bid is way under scrap, but in a sealed auction she'd have no way of knowing.
[18:30:09] <XXCoder> or do it yourself using jury rig system
[18:30:12] <andypugh> Much more than that and you start looking at paying professional movers.
[18:30:35] <andypugh> Anyway, sleep beckons.
[18:31:24] <furrywolf> it's only a couple gallons of gas from here, and I know someone with a car trailer... if they have heavy equipment to load it (which I believe they do), it's only unloading it that'll be annoying.
[18:31:34] <furrywolf> there's a guy up the road with a forklift who'd help me unload
[18:31:54] <furrywolf> the problem is a) paying for it, and b) putting it somewhere. it'd have to join the equipment under tarps in the driveway...
[18:32:23] <XXCoder> you has land? if so why not knock up a cheap shed
[18:32:46] <furrywolf> no has land. tiny lot.
[18:33:40] <furrywolf> XXCoder: if it can run os/2, it can probably run linuxcnc... :P
[18:33:53] <XXCoder> furrywolf: tell that to boss
[18:35:27] <furrywolf> right now I have my 15x6 planer, dust collector, an a/c unit, a stack of paint cans, a stack of battery cables, and 17 honda generators, under tarps in the yard...
[18:35:34] <furrywolf> oh, and the wood chipper
[18:35:47] <XXCoder> its pretty badly written, if it tries to load program using serial that dont exist, it will freeze for around 10 minutes then crash
[18:36:00] <XXCoder> be damn sure file exists on server lol
[18:36:39] <Tom_itx> so don't get it then. it'll just sit around and rust
[18:36:59] <XXCoder> unless like magic, nobody else bid and you win it for $10
[18:38:13] <furrywolf> yeah, my planer is looking pretty rusty...
[18:38:46] <furrywolf> it's just a grizzly, at least.
[18:39:49] <furrywolf> I don't remember the exact model number, but it's very similar to https://auctionimages.s3.amazonaws.com/63985/27043/18417918.jpg
[18:44:10] <furrywolf> I'll probably go there, make a small bid on everything, and head home and wait for the phone call that won't come. heh.
[18:44:24] <XXCoder> lol
[18:44:40] <XXCoder> make sure you can afford winning it too
[18:44:44] <XXCoder> haul cost and such lol
[18:44:52] <furrywolf> that's what credit cards are for! :P
[18:46:44] <XXCoder> :)
[18:46:56] <furrywolf> I don't much need an injection molding machine, but I have seen that machine (I got a quick tour of there once), and it is NEW. like, they've never actually injection molded anything.
[18:47:16] <furrywolf> I was giving a ride to someone who went there, and he showed me around.
[18:47:31] <SpeedEvil> Lies.
[18:47:40] <SpeedEvil> Everybody needs an injection molding machine
[18:47:47] <XXCoder> injection molding not bad. if you can create molds using cnc machine
[18:47:52] <furrywolf> too bad they're not auctioning off the new 5-axis machining center and the other really shiny bits. :P
[18:47:58] <XXCoder> great way to make lots cheap stuff I guess
[18:48:16] <XXCoder> new machines is all busy trying to pay for themselves
[18:48:16] <SpeedEvil> Pity GFRP is a bit tough to mold
[18:48:41] <furrywolf> the guy I picked up made some motorcycle triple-trees on the 5-axis machine...
[18:49:06] <Valen> SpeedEvil: tough to mould?
[18:49:29] <SpeedEvil> Valen: It wears the tooling with all the glass and is hard to pump IIRC
[18:49:51] <furrywolf> yeah, I can imagine that eating expensive bits pretty quickly.
[18:50:09] <Valen> I'm lacking context for the conversation, but my dad was in fibreglass for 30 years
[18:50:47] <Valen> moulding it when its wet is pretty easy
[18:50:57] <Valen> cutting it after its cured isn't that bad
[18:50:58] <SpeedEvil> Valen: not that sort
[18:50:58] <furrywolf> Valen: there's an injection molding machine coming up at a local auction
[18:51:10] <Valen> ahh, he made a few of those
[18:51:20] <SpeedEvil> Valen: you take tiny chopped strand fibreglass, and mix it into plastic, then injection mold that
[18:51:27] <SpeedEvil> rather than set it with a resin
[18:51:33] <XXCoder> Valen: we turn fiberglass blocks to parts at my work
[18:51:41] <XXCoder> man it makes HUGE mess
[18:51:44] <Valen> I believe that's dough moulding
[18:51:48] <XXCoder> and it dulls tools so fast
[18:52:08] <Valen> you need a different grind on the tools (at least for drills)
[18:52:18] <Valen> I have no idea what it is though lol
[18:53:30] <XXCoder> oh its not too bad, most tools use those replacable teeth
[18:53:47] <XXCoder> only big 1 inch em has to be replaced once a while
[18:54:02] <XXCoder> after say 25 parts or so
[18:54:12] <XXCoder> its fiberglass powder thats nasty
[18:54:21] <Valen> when they were trimming stuff they had diamond tools made
[18:54:24] <XXCoder> its like shoveling sand out of coolant bins
[18:54:24] <Valen> they lasted forever
[18:54:53] <XXCoder> very fine sand, that turns into nice and handy itchy powder on skin if splashed
[18:56:39] <furrywolf> I hate working with fiberglass.
[18:57:38] <Valen> if you are doing a lot of it I'd take a look at getting some diamond grinding tools
[18:57:53] <Valen> you can rip through it, it'll give you a good edge as a rule too
[18:57:57] <XXCoder> its actually uncommon
[18:58:11] <XXCoder> each few months we make 35 parts of 3 variants
[18:58:26] <XXCoder> coworker says it used to be say 3 times a year
[18:58:39] <XXCoder> 2 actually but nowdays seems 4 times
[18:59:07] <XXCoder> I worked there 5 months now and so far 2 times
[19:04:17] <XXCoder> anyway
[19:04:46] <XXCoder> I plan to bring my router to work and use work er8 see if it works
[19:04:48] <XXCoder> if it does woot
[19:05:00] <XXCoder> highly doubtful even though seller said it would
[19:09:56] <XXCoder> wow
[19:09:58] <XXCoder> http://a5.img.talkingpointsmemo.com/image/upload/w_652/dhtn4oywmy6hvbfmpjut.jpg
[19:10:02] <XXCoder> pluto halo
[19:10:12] <XXCoder> haze
[20:55:27] <sector_0> does anyone here mill stuff for a reasonable fee?
[21:00:06] <Tom_itx> i mill my stuff for free
[21:00:57] <Tom_itx> couple here might, depends where you are
[21:04:26] <CaptHindsight> you mean like for money?
[21:12:31] <sector_0> CaptHindsight, yeah
[21:12:53] <sector_0> I live in the Caribbean
[21:13:52] <skunkworks> maybe for a place to stay....
[21:13:57] <skunkworks> :)
[21:14:28] <sector_0> skunkworks, hehe
[21:15:12] <sector_0> well I have an extra room, and there's a view of the sea
[21:15:38] <sector_0> ...from the porch that is lol
[21:46:42] <Tecan> im a little envious even though the sea smells pretty rank sometimes
[21:53:59] <furrywolf> eh, I live near the sea. it's not that special. lol
[21:55:55] <sector_0> well i don't actually live near it, I live on a hill so i have a view of it, but it's still a good distance off
[21:56:50] <furrywolf> we have tsunami evacuation route signs. :P
[21:57:11] <sector_0> lol yeah I not that close
[21:57:58] <sector_0> but if a tsunami does hit I have a good vantage point though :p
[21:58:11] <furrywolf> well, I'm far enough inland that there's no signs here, but it is shown on the flood map.
[21:58:33] <furrywolf> I'm a bit up a hill.
[22:04:44] <renesis> 02:31 < furrywolf> eh, I live near the sea. it's not that special. lol
[22:04:49] <renesis> ocean is awesome
[22:05:11] <renesis> i miss it when im up north but is nice being home so shrug
[22:25:56] <zeeshan> a little confused on g28
[22:26:11] <zeeshan> when i do g28.1 it stores the current absolute position in 5161 ?
[22:26:18] <zeeshan> G28.1 - stores the current absolute position into parameters 5161-5166.
[22:26:20] <zeeshan> how do i know which one?
[22:26:40] <cradek> it saves xyzabcuvw in those nine variables
[22:26:44] <cradek> there's only one g28 position
[22:26:47] <zeeshan> yes, but which one?
[22:26:49] <furrywolf> so, reading the news about how new chrysler vehicles expose everything to a public ip with no authentication or security of any kind. one of the things people claim to have done is disable the brakes. how can you design a vehicle so incredibly poorly that braking is under software control?
[22:26:49] <zeeshan> hm
[22:26:57] <cradek> don't worry about the numbers
[22:27:01] <cradek> just use g28.1 and then later use g28
[22:27:19] <zeeshan> 5161 - 5166 -- is it basically updating the absolute position in all workpiece coordinates?
[22:27:25] <zeeshan> like g54 to g59.3
[22:27:32] <cradek> furrywolf: ABS is all about computer control of brakes
[22:27:34] <zeeshan> (just trying to understand it)
[22:27:47] <cradek> furrywolf: why it's hooked to the entertainment system is a better question
[22:27:59] <zeeshan> cradek are you using g28 as your tool change position?
[22:28:13] <cradek> g30 can be used for tool change position
[22:28:22] <cradek> yes I do that on my lathe with the tool turret
[22:28:29] <zeeshan> sweet :)
[22:28:35] <zeeshan> im about to try rigid tapping in a real chunk of metal
[22:28:38] <zeeshan> i hope it goes well
[22:28:55] <cradek> g28/g30 don't care about any offsets
[22:29:11] <zeeshan> yes, so its basically a safe thing to call
[22:29:14] <zeeshan> for tool changes
[22:29:20] <zeeshan> as long as the tool change position is somwhere safe
[22:29:32] <cradek> yeah it's good for that
[22:29:55] <cradek> put a long tool on the turret, you have to move it over more, so move it where you like it and do g30.1
[22:30:07] <furrywolf> cradek: every ABS system I've worked on still has a master cylinder that will supply pressure to the brakes even if the computers fail...
[22:30:23] <furrywolf> any design where a software issue, even an intentional one, can prevent the mechanical system from working, should never have been shipped.
[22:30:28] <cradek> furrywolf: sure but how about if the computers run an attacker's code
[22:30:58] <furrywolf> it should have mechanical or hardwired systems, and fail safe.
[22:30:59] <cradek> the whole point of abs is the computer can override your foot's pressure and let the wheels keep turning
[22:31:28] <cradek> it's not being a computer that's the problem
[22:31:54] <furrywolf> on every system I've worked on, the computer is self-contained, and generally built so it can't do stupid things.
[22:31:55] <cradek> it's hooking that computer to the cellphone and wifi and mp3 player and video games and whatever all else bs they put in cars now
[22:32:20] <furrywolf> the only thing I have with ABS is my van, and I've been tempted to yank the fuse from it several times... plain out bad idea.
[22:32:55] <cradek> my 13 yr old car has the radio and the abs and the airbag controller on the same bus (I know because I can read them all over the obd2)
[22:33:06] <renesis> ha wtf
[22:33:12] <cradek> and that's perfectly fine if you don't have cell phone or wifi bs going on
[22:33:15] <furrywolf> I had a BMW like that. I sold it. piece of shit.
[22:33:33] <renesis> ive gotten used to the abs kicking it
[22:33:37] <cradek> I bet every car in the last 10-15 years is set up like that
[22:33:41] <renesis> first few times i thought my brakes blew up
[22:33:45] <furrywolf> I've found ABS to greatly decrease control of the vehicle and increase stopping distance... it's a bad idea in general.
[22:34:06] <cradek> I wish it could be disabled when it's working against you (snow)
[22:34:10] <furrywolf> heh, on a ford truck I had, the abs unit got replaced by a pair of brass couplers. :)
[22:34:12] <renesis> happens to early, other cars i was used to braking until the edge of the tires letting go
[22:34:16] <renesis> and then backing off
[22:34:34] <renesis> stupid drivers stomping out the pedal when they get scared ruining it for everyone
[22:34:37] <cradek> the traction control stuff can usually be disabled in those situations, but not abs
[22:35:00] <furrywolf> I don't own anything with traction control. lol
[22:35:09] <furrywolf> unless you count the detroit locker for the truck. :)
[22:35:12] <renesis> pretty sure mine doesnt have traction control
[22:35:27] <renesis> i can spin wheels while turning like whatever
[22:35:33] <cradek> my 03 has it, and it has kept me on the road once in the 10 years I've driven it
[22:36:08] <cradek> it's been in the way dozens of times (snow), but it has a disable button
[22:36:15] <zeeshan> question about rigid tapping
[22:36:30] <renesis> the ABS maybe helped on some canyon uh-ohs, but for all i know i could have gotten a lot more deccel mannually modulating the wheel slip
[22:36:32] <zeeshan> if i specify G33.1 Z-.425 K.04167, when does linuxcnc command the reversal
[22:36:33] <zeeshan> at .425?
[22:36:42] <cradek> yep
[22:36:47] <zeeshan> so there will be some overshoot
[22:36:50] <cradek> yep
[22:36:51] <furrywolf> my bmw had traction control, but it never actually seemed to do anything. the piece-of-utter-shit transmission controller made sure you never got enough torque to the wheels to spin them whether the traction control was on or off.
[22:37:13] <cradek> zeeshan: http://linuxcnc.org/docs/html/gcode/gcode.html#sec:G33_1-Rigid-Tapping
[22:37:17] <zeeshan> im really curious to see how much overshoot changes when youre actually tapping
[22:37:18] <cradek> when in doubt... :-)
[22:37:32] <renesis> furrywolf: you had an auto bmw?
[22:37:41] <cradek> depends on how much load you're under I guess
[22:37:46] <Tom_itx> zeeshan, i often use G28 Z0; G28 Y0 to move the spindle up and bring the table out to change parts
[22:37:50] <cradek> my vmc doesn't notice at all when it's tapping
[22:37:54] <furrywolf> "We're making a 7 series. It's meant to be driven by senile people who drive 15mph under the speed limit with their blinker on all day. They don't like any sudden movements. I know! We'll make the transmission always start in 2nd gear, and simply disable 1st gear, so it's nice and smooth!"
[22:37:58] <cradek> (I rarely tap over 1/4)
[22:38:10] <zeeshan> hehe
[22:38:12] <zeeshan> what vmc do you have
[22:38:20] <cradek> a mori mv jr
[22:38:24] <furrywolf> "Let's build a car with a 280hp engine that can't break the tires free!"
[22:38:27] <Tom_itx> lucky dog
[22:38:37] <zeeshan> beast
[22:38:39] <zeeshan> Tom_itx: i see
[22:38:47] <renesis> furrywolf: its an auto transmission?
[22:38:49] <cradek> bad photo: http://timeguy.com/cradek-files/emc/jr.jpg
[22:39:02] <zeeshan> i guess you specify Z0 with the g28 because you want to ensure you're above the current work piece
[22:39:09] <zeeshan> before trying to go to the predefined position for even more safety
[22:39:15] <furrywolf> renesis: no, I'm talking about automatic transmission controllers, software control of gears, etc, for the manual transmission.
[22:39:17] <zeeshan> ooo
[22:39:19] <zeeshan> is that an ATC i see
[22:39:27] <jdh> cradek: is the framed in ceiling just for clearance?
[22:39:28] <cradek> of course
[22:39:32] <cradek> jdh: haha yes
[22:39:33] <Tom_itx> otherwise they'll move at the same time which could be bad
[22:39:39] <cradek> jdh: needed a few more inches...
[22:39:48] <renesis> furrywolf: so it was clutched?
[22:39:52] <zeeshan> this might be a retarded question
[22:40:00] <zeeshan> but why is one tool on the overarm
[22:40:10] <zeeshan> is that a probe or something
[22:40:19] <cradek> that's the probe. at the time, it had the wrong shank on it and couldn't go in the tool changer
[22:40:25] <zeeshan> ah
[22:40:32] <cradek> nowadays it's in the tool changer
[22:40:32] <furrywolf> renesis: no, you're just either blind or drunk, and if you can't pay enough attention to figure out that it's an automatic, I'm not going to talk to you.
[22:40:34] <zeeshan> nice machine
[22:40:53] <cradek> I cut down a weldon style tool holder for it
[22:40:55] <Tom_itx> too darn clean
[22:41:16] <cradek> this machine caused touchy to be written
[22:41:25] <cradek> also random toolchange
[22:41:35] <renesis> furrywolf: you ended the sentence with 'for a manual transmission' so was confusing, also its me so way more likely to be stoned than drunk
[22:41:38] <Tom_itx> looks like a nice rotary head on the floor too
[22:41:42] <Tom_itx> or indexer...
[22:41:48] * furrywolf gives up
[22:41:49] <cradek> yeah 12". it's cnc now too
[22:42:09] <furrywolf> renesis: you're now the official designated helper of Just_pink when they're here.
[22:42:31] <renesis> just pink is a they?
[22:42:51] <furrywolf> yes.
[22:42:55] <renesis> china factory irc client with designated photo model, noice
[22:42:59] <Tom_itx> he, she, he-she, it?
[22:43:06] <cradek> some people are theys
[22:43:08] <renesis> shrug
[22:43:09] * zeeshan is trying to figure out the atc on your machine
[22:43:14] <zeeshan> its 90 degrees to the spindle
[22:43:15] <cradek> nobody's an it, afaik
[22:43:21] <zeeshan> is there an arm or something that grabs it
[22:43:39] <cradek> zeeshan: the selected (bottom) pot turns downward, and the arm swings and swaps that tool with the spindle tool
[22:44:00] <Tom_itx> one of the Okumas we had used a swing arm
[22:44:01] <furrywolf> I think I'll stick to my driving of vehicles that do not have highly integrated computer systems nor cellular modems.
[22:44:33] <Tom_itx> 99tool belt with a swingarm and tool prefetch
[22:45:11] <renesis> i dont like drive by wire, feels shit, and syncing the filtered digital gas with the hydraulic clutch is a mess
[22:45:29] <cradek> zeehan: you can see a tool change here: https://www.youtube.com/watch?v=eWitrmtqZ7I
[22:46:00] <zeeshan> lol
[22:46:05] <zeeshan> im glad you posted that video, i was imagining it completely wrong.
[22:46:16] <zeeshan> didn't realize the tool came back in the same plane as the spindle
[22:46:23] <Tom_itx> yep
[22:46:29] <zeeshan> do you have a shot with the atc cover off?
[22:46:34] <zeeshan> to see how it indexs the tool like that
[22:46:44] <cradek> a big geneva wheel
[22:46:56] <cradek> run by a plain 3 phase ac motor
[22:47:59] <cradek> cool, it shows probing, I forgot about this video
[22:48:28] <zeeshan> the spindle is run by a 3 phase motor as well?
[22:48:35] <zeeshan> i notice the spindle indexs
[22:48:43] <cradek> yes
[22:48:49] <zeeshan> how do you manage that?
[22:48:49] <Tom_itx> it has to
[22:49:01] <cradek> the index is mechanical - there's a roller that rolls down a ramp and into a hole
[22:49:06] <zeeshan> ahh
[22:49:12] <cradek> a switch says when it's in the hole
[22:49:29] <zeeshan> okay i was thinking it was position controlled somehow through a motor controller
[22:49:41] <cradek> that never works as well as a pin
[22:49:50] <zeeshan> positive index is the best
[22:51:01] <cradek> the spindle vfd has a "jog" input that moves slowly with low torque
[22:51:16] <cradek> then when the pin pops in the hole it turns off and ladder continues
[22:51:26] * furrywolf needs a machine fancy enough to have things like that. :(
[22:51:42] <zeeshan> furrywolf: https://www.youtube.com/watch?v=Wx4mKtlJeIs
[22:51:43] <zeeshan> ROFL
[22:51:46] <zeeshan> i think you'll enjoy this one
[22:51:49] <cradek> machines that came as cnc have a lot of nice features
[22:52:04] <cradek> people who retrofit manual machines have a much harder time
[22:52:04] <zeeshan> cradek mine came cnc, but doesnt have that!! :{
[22:52:10] <furrywolf> machines that cost more than the $100 I spent on mind tend to be better, too. heh.
[22:52:23] <cradek> ha, yeah
[22:52:51] <zeeshan> this video is making me giggle
[22:52:55] <zeeshan> i dont know why its so funny
[22:53:01] <zeeshan> if the airbag came out
[22:53:09] <zeeshan> or the fact that it's hopping around like a bunny
[22:55:13] <furrywolf> why are they stopped?
[22:55:16] <furrywolf> that should not have damaged the vehicle.
[22:55:29] <zeeshan> dude the airbag went off
[22:55:30] <furrywolf> at least not in any way to make it unable to safely exit the road.
[22:55:30] <cradek> airbag popped. probably disables the car?
[22:55:33] <zeeshan> it prolly so a lot of g's
[22:55:47] <cradek> I wonder what the horn is
[22:56:05] <furrywolf> cradek: I've only seen a few vehicles with the airbags set off, but none disabled the car. that would be VERY unsafe. it prevents you from getting out of traffic to prevent follow-on collisions.
[22:56:12] <renesis> it bottomed the bumper, everything prob bump stopped, its allowed to be damaged
[22:56:39] <zeeshan> lesson: don't speed over railway tracks
[22:56:40] <cradek> furrywolf: a lot disable the fuel pump in an accident, so it doesn't keep pumping all the fuel out.
[22:56:58] <zeeshan> cradek: modern cars probably
[22:57:03] <cradek> furrywolf: fords at least have a reset button
[22:57:05] <zeeshan> at the track we need kill switches for that exact reason
[22:57:06] <cradek> last 20 years
[22:57:08] <furrywolf> cradek: only one I've seen that disables the fuel pump is old ford trucks with an impact-activated switch. everything else seems to tie it to engine rpms.
[22:57:11] <zeeshan> cause the fuel pump keeps pumping fuel even during a crash
[22:57:20] <zeeshan> which not only kills the person in the car, but the track crew also
[22:57:24] <zeeshan> when it goes kaboom
[22:57:36] <furrywolf> subaru, for example, requires pulses from the ignition system to keep the fuel pump on.
[22:57:52] <zeeshan> really?
[22:57:54] <zeeshan> we have a watchdog?
[22:58:15] <furrywolf> on '80s subarus, yes. new ones control the fuel pump from the ecu, which requires cam sensor pulses. :P
[22:58:19] <zeeshan> brb from mill, really wanna try this tapping
[22:58:37] <zeeshan> well thats how it works on the fd rx7
[22:58:41] <zeeshan> and even my old mitsu
[22:58:58] <zeeshan> the engine rpm has to be above 400 to keep pumping fuel
[22:59:36] <furrywolf> carb subarus, at least in the '80s, have a little module under the dash (far left side, six-pin plug) that only turns the fuel pump on if there's pulses from the distributor. no dist pulses, fuel pump turns off.
[23:00:43] <furrywolf> '70s subarus ran the fuel pump off the alternator voltage regulator. alternator not spinning, no fuel pump.
[23:01:02] <furrywolf> '90s subarus run it off the ecu, based on rpm.
[23:02:18] <furrywolf> older cars had mechanical fuel pumps, which were also dependent on engine rpm. :)
[23:02:30] <zeeshan-mill> engine rpm seems good enough
[23:02:34] <zeeshan-mill> > 200 rpm , enable pump
[23:02:58] <zeeshan-mill> not sure why they need ignition pulses
[23:03:15] <furrywolf> old ford trucks had a switch stuffed under the dashboard on the passenger side, with a reset button on top. I've NEVER seen one popped. Even ones that took out trees, telephone poles, etc.
[23:03:30] <cradek> huh
[23:03:41] <cradek> I thought the trunk...?
[23:04:06] <zeeshan-mill> what was going through subaru's engineers' minds
[23:04:11] <furrywolf> as I said, CARBED engines... how do you determine the rpm of a carbed engine without looking directly at the ignition system? :P
[23:04:21] <furrywolf> cradek: trucks don't have trunks. :)
[23:04:24] <zeeshan-mill> this bliz tap holder has 1/8" of play
[23:04:29] <zeeshan-mill> i hope thats enough to stop a tap from snapping
[23:04:43] <furrywolf> maybe they stuck it in the trunk on cars, but I haven't done much work on ford cars, generally considering them not worth fixing...
[23:05:29] <furrywolf> I've worked on a couple fox body mustangs and t-birds, but didn't have a reason to notice if they had a fuel switch.
[23:06:00] <furrywolf> ugly a very, very slow. :)
[23:06:10] <cradek> I had a mustang. it was crap. I was tickled when I traded it in.
[23:06:26] <furrywolf> let's choke a 5.0 V8 with so much smog crap it makes 120HP!
[23:06:55] <furrywolf> mustangs started really sucking in the late '70s.
[23:07:58] <zeeshan-mill> rustang
[23:08:40] <furrywolf> my 4-banger subaru has more horsepower than most mid-'70s to mid-'90s mustangs.
[23:09:05] <CaptHindsight> FORD, Fix Or Repair Daily :)
[23:09:26] <furrywolf> CaptHindsight: if you put firestone tires on, then they Flip On Rapid Deflation. :P
[23:10:18] <furrywolf> actually, despite all the bitching about fords, the '80s and '90s trucks are actually rather reliable. they usually have about a million small things wrong, but keep driving.
[23:10:19] <CaptHindsight> my last Mustang was a 72 Mach 1, what a boat
[23:10:50] <cradek> my ex's 96 bronco is still going strong
[23:11:03] <cradek> I still borrow it once in a while :-)
[23:11:05] <furrywolf> every power steering gearbox goes out. every tiltwheel goes out. every zf5 shifter breaks. every plastic door handle breaks off (swap in an earlier metal one!), etc... but they keep driving.
[23:11:29] <furrywolf> cradek: if you want fun with full-size broncos, the roofs fall off if you drive on enough dirt roads. :P
[23:11:35] <furrywolf> oh, and every radiator core support cracks
[23:11:45] <furrywolf> every eec iv wiring harness has flaking insulation
[23:11:56] <cradek> water pump rusts into place
[23:12:08] <cradek> a sawzall fixes that, haha
[23:12:17] <cradek> takes boldness to put a water pump in it
[23:12:20] <furrywolf> every 7.3 glowplug controller that hasn't been rebuilt and had the glowplugs replaced rapid cycles and doesn't start on cold days.
[23:12:37] <furrywolf> every 7.3 and 6.9 fuel system sucks air
[23:13:25] <furrywolf> they have a lot of issues, but generally go quite a few miles before major things break.
[23:13:25] <cradek> I drove a ford V10 moving truck recently. it got 2 miles to the dollar.
[23:13:31] <furrywolf> lol
[23:13:36] <furrywolf> my truck is like that.
[23:14:02] <cradek> I put gas in my car once a month whether it needs it or not
[23:14:15] <furrywolf> except I have a 230 6-cylinder. it's so underpowered you drive with your foot flat to the floor all the time (it's like cruise control, which it doesn't have), causing it to get utter shit milage.
[23:14:27] <furrywolf> let's put a 120hp engine in a 6500lb truck! :)
[23:15:01] <furrywolf> I burn a lot of gas. living in a rural area does that.
[23:15:10] <furrywolf> my subaru gets gassed up every week or so.
[23:15:19] <furrywolf> van (with its lovely 35gal tank) every two weeks.
[23:15:54] <furrywolf> truck.. every time I drive it. which isn't very often. it needs some work before it's roadworthy at the moment.
[23:16:26] <furrywolf> if you want good gas milage, get a ford 460. they can pass everything except a gas station. :)
[23:16:30] <furrywolf> a friend once measured 4mpg.
[23:16:51] <furrywolf> they came with the dual tanks stock, holding over 50 gallons... so you can go about 300 miles between fillups.
[23:17:45] <cradek> I'm secure enough in my masculinity to not need a car like that
[23:18:58] <furrywolf> they make good work trucks... you can put a literal ton of weight in the bed and they truck right up hills happily...
[23:20:32] <furrywolf> while my truck has a hard time going 55mph up a hill empty!
[23:20:36] <zeeshan-mill> tap.. please dont break :{
[23:21:15] <furrywolf> tap balsa first.
[23:21:19] <furrywolf> or air. :P
[23:21:57] <furrywolf> if I got another truck, it'd probably be an early-mid '90s f-350 with a 7.3 and zf5.
[23:21:59] <cradek> tap a nut with a bolt, heh
[23:22:02] <zeeshan-mill> rofl
[23:22:06] <zeeshan-mill> its only aluminum
[23:22:16] <furrywolf> aluminum WILL break taps.
[23:22:34] <furrywolf> you have to cut wood to save the tap if something screws up. heh.
[23:23:24] <furrywolf> of all the trucks I've worked on, the later 7.3s with manual transmissions seem to be the most reliable.
[23:23:31] <furrywolf> don't ever get a chevy or a dodge.
[23:23:49] <furrywolf> well, of all the full-size trucks. for toy trucks, get a toyota with a 22re. they'll run forever.
[23:24:28] <zeeshan-mill> hmm wtf am i doing wrong
[23:24:34] <zeeshan-mill> my red box is below my program
[23:24:36] <zeeshan-mill> Hmmmm!
[23:25:33] <furrywolf> other than regular replacements of head gaskets and main oil seals, the 22re is a quite reliable engine.
[23:25:51] <furrywolf> and sticky idle air valves.
[23:26:47] <zeeshan-mill> son of a bitch
[23:26:58] <zeeshan-mill> i did something wrong when doing all my tool touch offs
[23:27:04] <zeeshan-mill> i was touching the table and hitting Z = 0
[23:27:11] * furrywolf sends zeeshan a 20-pack of taps
[23:27:20] <zeeshan-mill> with tool touch off to fixture
[23:28:01] <zeeshan-mill> cradek can you guide me :{
[23:28:13] <zeeshan-mill> you are actually here late :P
[23:28:20] <cradek> I'm sooooo tired
[23:28:37] <furrywolf> I am too. I got about an hour of sleep last night. back was hurting too much.
[23:28:41] <zeeshan-mill> aww
[23:28:46] <zeeshan-mill> but it will take 10 min!!
[23:29:04] <zeeshan-mill> i followed jt's guide on his website
[23:29:07] <zeeshan-mill> which i think he learned from you
[23:29:30] <cradek> surely I'm not the source of all tool measuring wisdom in the world
[23:29:37] <furrywolf> are you sure?
[23:29:38] <zeeshan-mill> everyone refers to you
[23:29:38] <zeeshan-mill> haha
[23:29:42] <cradek> grrrngh
[23:29:52] <cradek> did you g43 after you loaded the tool?
[23:29:54] <zeeshan-mill> yes
[23:30:01] <zeeshan-mill> i removed all g92 offsets
[23:30:14] <zeeshan-mill> selected tool touch off to fixture (machine was homed)
[23:30:15] <cradek> do the tool lengths make sense?
[23:30:15] <furrywolf> zeeshan-lab: as I told you before, send me a machine with a tool changer, then I'll let you know how to set one up. :P
[23:30:31] <zeeshan-mill> did t1 m6 g43, touched a dowel and hit tool touch off and z=0.
[23:30:36] <zeeshan-mill> and i repeated this for all my tools
[23:30:40] <zeeshan-mill> the relative position of all the tools makes sense
[23:30:46] <cradek> ok then it's fine
[23:30:57] <cradek> so what's wrong?
[23:31:06] <zeeshan-mill> now i went it selected tool 6 , m6 g43 and selected "tool touch off to workpiece"
[23:31:08] <PetefromTn_> don't you need H1?
[23:31:20] <furrywolf> I'll probably get a tool height sensor to aid with manual tool changes.
[23:31:22] <cradek> no no
[23:31:24] <zeeshan-mill> and touched off the top of my work piece
[23:31:29] <cradek> don't nuke your tool length
[23:31:54] <cradek> set a work offset (g54) for your workpiece
[23:32:18] <zeeshan-mill> ah shit
[23:32:21] <zeeshan-mill> okay let me fix this tool
[23:32:24] <cradek> load any tool, g43, touch the work, touch off (NOT tool touch off) z=0
[23:33:43] <zeeshan-mill> okay tlo z is still the same
[23:33:47] <zeeshan-mill> so i didnt nuke the tool offset :)
[23:34:22] <furrywolf> bbl
[23:34:37] <cradek> g'night wolfie
[23:34:49] <furrywolf> cyas :)
[23:35:46] <zeeshan-mill> i did that
[23:35:52] <zeeshan-mill> and i have the same problem :(
[23:36:35] <cradek> which workpiece system did you touch off?
[23:36:55] <zeeshan-mill> g54
[23:37:13] <cradek> are you in g54?
[23:37:15] <zeeshan-mill> yes
[23:37:19] <zeeshan-mill> pic coming up
[23:37:23] <cradek> ok
[23:38:43] <zeeshan-mill> http://i.imgur.com/TQOUJgi.png
[23:38:55] <zeeshan-mill> my workspace is all below my program
[23:39:24] <zeeshan-mill> its calling a g28
[23:39:27] <cradek> I see a g49 on line 8
[23:40:37] <zeeshan-mill> i thought you were supposed to call g49 at the beginning of the program
[23:40:42] <cradek> I suspect your tool lenghts are crazy big
[23:40:44] <zeeshan-mill> to ensure no tool offsets were active
[23:40:52] <cradek> well if you have no TLO your program will be in a really wrong place
[23:41:02] <cradek> or is the tool change after this?
[23:41:09] <zeeshan-mill> tool change is after this
[23:41:20] <cradek> pastebin the gcode?
[23:41:34] <PetefromTn_> what exactly is the problem?
[23:42:06] <cradek> don't know yet
[23:42:11] <cradek> the program's not where he expects
[23:42:31] <zeeshan-mill> http://pastebin.com/NQgVJcV7
[23:42:44] <zeeshan-mill> PetefromTn_, you dont need to call h1 after
[23:42:52] <zeeshan-mill> when you do g43 it loads the associated tool offset by itself
[23:42:55] <zeeshan-mill> its better not to call hxxx
[23:43:09] <zeeshan-mill> cause i made the mistake of doing t3 m6 g43 h6 before
[23:43:13] <zeeshan-mill> and cradek caught that
[23:43:29] <zeeshan-mill> if the cam is outputting it, i let it write the register
[23:43:33] <zeeshan-mill> but i never do it manually anymore
[23:45:12] <cradek> this all looks pretty plausible
[23:45:31] <zeeshan-mill> what is funny is im jogging outside of the work area
[23:45:36] <zeeshan-mill> so im not sure what is going on there
[23:45:51] <zeeshan-mill> (as indicated by the yellow line
[23:45:56] <PetefromTn_> I always do and never had a problem
[23:48:22] <zeeshan-mill> http://i.imgur.com/eQdml78.png
[23:48:25] <zeeshan-mill> that is what the dro shows
[23:49:02] <cradek> if you stick a ruler between the work and tool tip is it 8.3 inches?
[23:49:22] <cradek> I don't like TLOs being that big, but whatever as long as they are consistent
[23:49:32] <cradek> big negative is better than big positive
[23:50:20] <Tecan> the big one
[23:51:12] <zeeshan-mill> yea ruler shows 8.33 "
[23:51:16] <zeeshan-mill> 8.3
[23:51:19] <zeeshan-mill> ~
[23:51:22] <cradek> then it's fine
[23:53:37] <zeeshan-mill> weird
[23:53:38] <zeeshan-mill> the program runs
[23:53:40] <zeeshan-mill> without erroring out
[23:54:11] <cradek> I bet the preview is weird because you have moves without TLO applied
[23:54:26] <cradek> see N130 is a motion
[23:54:51] <zeeshan-mill> so i should be calling g43
[23:54:52] <zeeshan-mill> right away
[23:55:00] <cradek> I sure would
[23:55:00] <zeeshan-mill> not doing the move first
[23:55:02] <zeeshan-mill> lemme fix that
[23:56:06] <zeeshan-mill> didnt fix
[23:56:34] <cradek> did you fix all 3?
[23:56:39] <Tecan> do you guys ever think this is a simulation ever ?
[23:56:53] <cradek> I'm off to bed
[23:56:58] <cradek> hope you get it zeeshan
[23:57:01] <zeeshan-mill> yes
[23:57:03] <zeeshan-mill> all 3
[23:57:07] <zeeshan-mill> cradek thanks for your help
[23:57:12] <cradek> welcome
[23:57:30] <Tecan> gnite cradek ;)
