[02:48:26] <t4nk988> help
[02:49:09] <tiwake> https://www.youtube.com/watch?v=zLvYUkagKPg
[02:51:48] <t4nk988> impressive
[07:12:42] <Jymmm> PCW: pcw_home https://www.youtube.com/watch?v=KC6WDxPSrZ8
[07:15:45] <redlegion> Have you guys heard that there's a shortage of CMM programmers?
[07:16:11] <redlegion> I've had multiple people tell me that and I can't imagine why there would be a shortage.
[07:31:28] <Tecan> nice trimslice
[07:31:59] <Tecan> how are they going to get 4k display without cooling though
[07:52:28] <_methods> because programming cmm's is boring
[07:52:43] <_methods> and everyone hates the quality guy?
[08:03:47] <Loetmichel> everyone always hates the QM guy ;-)
[08:15:38] <_methods> i know hehe
[08:32:08] <redlegion> This is true.
[08:32:32] <redlegion> "How can the true position be 8mm out!? Measure it again!"
[10:27:08] <DaPeace> hey guys, short question. i want to connect 2 buttons and want to use the signal halui.programm-is-running to check for the state.. linuxcnc complains that the signal is already in use.. any hint how to solve that?
[10:34:20] <r2e4> Mornin all
[10:36:05] <r2e4> i can see encoders counting in hal, does that mean they are connected properly?
[10:36:43] <SpeedEvil> Are they all counting the right way, on the right axes, at the right rates?
[10:56:03] <CaptHindsight> I have a question but I'll be logging out of the channel 2 minutes after I post it...
[10:57:19] <CaptHindsight> do some ISP's charge by the minute to connect to IRC or something?
[10:58:02] <SpeedEvil> Some iphone apps do that
[11:39:20] <ssi> CaptHindsight: did you get an unexpected bill?
[11:40:40] <CaptHindsight> ssi: just wondering why someone would ask a question here and log out 2 minutes later
[11:41:34] <CaptHindsight> besides ADD, too much amphetamine, under the age of 12, etc etc
[11:42:20] <ssi> lul
[11:42:38] <ssi> I guess not everyone leaves irc running in a screen session on a private server
[11:43:12] <ssi> speaking of which
[11:43:18] * ssi wanders off to find more amphetamine
[12:16:02] <Tom_itx> DaPeace, find the net name it's attached to
[12:27:18] <CaptHindsight> DaPeace: post your HAL config so people can see what you are trying to do
[12:39:59] <JT-Shop> DaPeace, use the signal not the pin
[12:41:41] <Deejay> Luke, use the force!
[12:56:31] <CaptHindsight> anyone have a small plastic injection molding machine they want to get rid of?
[12:56:48] <_methods> do they make small injection molders lol
[12:57:09] <CaptHindsight> heh, yeah for protos
[12:57:11] <_methods> i remember seein some guy was doing one diy
[12:57:14] <CaptHindsight> desktop
[12:57:21] <Jymmm> CaptHindsight: Yes I do (looks at glue gun)
[12:57:33] <ssi> _methods: there's a guy that made a cool little desktop injection molder that takes it to maker faire
[12:58:03] <CaptHindsight> hmm hot melt + artisnal wooden molds...... smells like a poopstarter
[12:58:19] <_methods> ssi: yeah i think that's the one i'm thinkin of
[12:58:24] <_methods> this one is kinda cool though
[12:58:27] <_methods> http://www.scorchworks.com/Injection_molding/injection_molding.html

[12:58:33] <_methods> arbor press injection molder
[12:59:05] <archivist> CaptHindsight, I see them sometimes on fleabay
[12:59:19] <CaptHindsight> more like http://www.morganindustriesinc.com/
[13:00:18] <CaptHindsight> I think the Morgan new costs more than a nice medium size used machine
[13:01:29] <CaptHindsight> someone offered me a 500 ton for a few $K
[13:01:58] <archivist> http://www.ebay.co.uk/itm/Injection-Moulding-machines-Austin-Allen-x2-230-240-v-/281847431614
[13:02:29] <_methods> https://www.youtube.com/watch?v=2P7MaZUrSQQ
[13:02:31] <_methods> that one
[13:03:03] <CaptHindsight> I know where to find em. I'm just checking if any of you guys have one
[13:03:12] <CaptHindsight> or gals
[13:03:25] <_methods> nope
[13:05:18] <archivist> faster to machine some plastic :)
[13:06:44] <CaptHindsight> http://www.ebay.com/itm/VAN-DORN-275-TON-INJECTION-MOLDING-MACHINE-/151873866592 $3200 if thats the reserve price for a 275 ton
[13:08:21] <CaptHindsight> this is for another project where they have money but no time
[13:09:29] <_methods> that's way better than the projects i usually get where they have no money AND no time lol
[13:09:36] <CaptHindsight> lol
[13:10:04] <Tom_itx> CaptHindsight, make one: http://www.users.qwest.net/~kmaxon/page/side/mold_mach_137.htm
[13:10:30] <CaptHindsight> by next week?
[13:10:50] <Tom_itx> hire a large workforce for a week
[13:11:09] <CaptHindsight> I'd have to rent port-a-potties
[13:11:19] <Tom_itx> oh, well forget it then..
[13:12:02] <_methods> wow that site...........
[13:12:20] <Tom_itx> yeah he's got / done alot of stuff
[13:12:31] <_methods> except clean up his website lol
[13:12:42] <Tom_itx> true
[13:12:57] <CaptHindsight> my eyes hurt but it's a nice change, sort of retro
[13:13:05] <_methods> sort of lol
[13:13:18] <_methods> straight out of the 90's
[13:13:44] <Tom_itx> could be when it was last updated :)
[13:14:37] <CaptHindsight> http://www.ebay.com/itm/Sumitomo-SH-75-Injection-Molding-Machine-C-250-Great-Price-/151828040646 $1950 or best
[13:20:16] <CaptHindsight> what is this? http://www.rakuten.com/prod/dragonfly-style-injection-molding-rotary-shader-tattoo-machine-red/285094145.html?listingId=436360656&sclid=pla_google_DealsDirect2U&adid=29963&rmatt=tsid:1012713|cid:223285369|agid:13828121329|tid:kwd-86359400689|crid:60879536569|nw:g|rnd:11570748586245319555|dvc:c|adp:1o5&gclid=CJPKivC498gCFYkXHwodEOIHtA
[13:24:55] <archivist> something suitable for use on your enemies
[13:26:16] <SpeedEvil> CaptHindsight: the sticky out bars I think run a motor to an eccentric crank
[13:38:06] <_methods> lol
[13:38:13] <_methods> frequently sold with soldering iron
[13:39:53] <CaptHindsight> that's a crazy site
[13:40:08] <_methods> yeah what did they used to be called?
[13:40:11] <CaptHindsight> "Shopping is Entertainment!"
[13:40:22] <_methods> i seem to remember it being something else before rakuten
[13:40:49] <_methods> ah buy.com lol
[13:41:09] <_methods> http://www.inc.com/geoffrey-james/worlds-dumbest-rebrand.html
[13:42:05] <CaptHindsight> This rebrand is so crazy that I have to assume that somebody inside the company has gone insane.
[13:42:42] <ssi> shit can I buy buy.com from them? :P
[13:44:03] <_methods> hehe
[13:44:07] <Jymmm> Can a clamp on amp meter be used on an extension cord?
[13:44:21] <CaptHindsight> if you split the cord
[13:44:30] <Jymmm> without splitting it
[13:44:37] <archivist> only of you can clamp only one conductor
[13:44:37] <ssi> yeah it'll work
[13:44:39] <_methods> Jymmm: i hope we're talking about an actual extension cord
[13:44:42] <ssi> it'll show you the sum of the currents in the cord
[13:44:48] <ssi> which will be zero unless there's crazyness involved
[13:44:50] <_methods> that Jymmm is always clampin stuff
[13:44:53] <Jymmm> ssi: sums?
[13:45:07] <ssi> yeah, positive current in the line, negative current in the neutral
[13:45:17] <archivist> +10 amps + -10 amps
[13:45:19] <ssi> should sum to zero
[13:45:33] <Jymmm> so it would cancel itself out?
[13:45:34] <ssi> if you can get the clamp on one conductor you'll get a valid current
[13:45:47] <ssi> hence the splitting
[13:46:26] <Jymmm> Well, it's jsut not always practical to be ablee to do that is why I was asking.
[13:46:29] <ssi> make a 6" pigtail extension cord with some thhn and screw-on plugs, use that for your clampmeter measurement
[13:48:32] <Jymmm> ssi: I mostly wanted to see the loads on rolmex circuits
[13:48:34] <CaptHindsight> you can also guestimate, did the cord melt in under a minute? No then most likely <50A
[13:48:52] <Jymmm> CaptHindsight: But but the cord was 4/0
[13:49:23] <ssi> Jymmm: understand, but physics isn't gonna let you do it that way :)
[13:49:50] <CaptHindsight> 4 number 0 or 0000?
[13:50:05] <Jymmm> CaptHindsight: big ass service lines =)
[13:50:08] <ssi> 4/0 is zero 4awg conductors :D
[13:50:11] <Wolf_> 4/0 is 0.46”
[13:51:45] <Jymmm> http://www.andybaird.com/travels/skylarking/2008/photos/4-0-cable.jpg
[13:51:58] <Jymmm> quantity = 1
[13:52:49] <ssi> ugh
[13:52:58] <Wolf_> only good for about 3.2kA
[13:52:59] <ssi> my miserably pedantic EE friend has pointed out
[13:53:09] <Jymmm> I'm trying to find a way to measure service on a hourly (or better) basis.
[13:53:15] <ssi> that what you will see won't be the sums of the currents, but twice the common mode current into the device
[13:53:36] <ssi> which will be non-zero due to a non-zero coupling capacitance of the device to the earth
[13:53:39] <ssi> (thanks eric)
[13:54:09] <CaptHindsight> is it possible to completely thermally isolate the entire structure that the cables go into? :)
[13:54:13] <Jymmm> I can't find cheap hall effects that will fit 4/0 cable, else I guess I can try hacking the smart meter
[13:57:19] <Jymmm> I need the 200A version of this http://www.ebay.com/itm/SCT-013-030-0-30A-Non-invasive-AC-current-sensor-Split-Core-Current-Transformer/140970837771
[13:58:50] <Jymmm> YAY 000Amps http://www.ebay.com/itm/Non-invasive-AC-current-sensor-SCT-019-200A-max-e-/251718202235
[14:01:06] <CaptHindsight> Jymmm: that's probably the lowest cost way to build it
[14:03:46] <Jymmm> CaptHindsight: Yeah, I' just tring to figure out the various model #'s and if I can get both voltage and current draw at the same time (see chart http://www.ebay.com/itm/Non-invasive-AC-current-sensor-SCT-019-200A-max-e-/251718202235)
[14:04:33] <Jymmm> CaptHindsight: I saw something like this using two sensor that did a parasitic tab to power itself too, but I dont know the details of it
[14:05:02] <Jymmm> CaptHindsight: I already have the RF modules to play with
[14:06:13] <Jymmm> 19mm opening, I'll have to measure the 4/0 and it's insulator, but I don't think that's big enough =(
[14:19:00] <Jymmm> ssi: I have a couple of kill-a-watt meters, but they are 110VAC only and limited to 15A
[14:20:30] <Jymmm> I'm trying to determine the HVAC -vs- Wood Stove costs and when best to use one over the other.
[14:21:19] <Jymmm> It's getting down in the 30'sF, so I can hear the heat pump going into defrost mode
[14:23:53] <SpeedEvil> http://www.ebay.co.uk/itm/Envi-Home-Cost-Energy-Saving-Electric-Smart-Meter-Monitor-Adapter-Transmiter-/281649252870?hash=item41939a8a06:g:1eYAAOSwrklVG8rT - for example
[14:24:07] <SpeedEvil> (does not measure volts)
[14:25:47] <Jymmm> SpeedEvil: Other than the 100A limit, yeah something like that, but where I can collect the data over time and compare it to in/outdoor temps, etc
[14:26:14] <SpeedEvil> I have mine hooked to USB
[14:26:29] <Jymmm> oh, it has a usb port?
[14:27:16] <SpeedEvil> My closely related one does

[14:47:49] <Jymmm> "Joule Thief"
[14:50:43] <Praesmeodymium> theres a joule thief in every shitty disposable camer
[14:51:01] <Jymmm> Praesmeodymium: ?
[14:51:29] <Praesmeodymium> something I ran across ages ago.. dun remember what for but the flash circuit has a joule thief on it
[14:51:44] <Jymmm> ah
[14:51:58] <Praesmeodymium> mighta been one of those days when I got trapped in youtube idiocy
[14:52:04] <Jymmm> hahaha
[14:52:10] <Praesmeodymium> look a stun gun from a camera or some such
[14:52:22] <Jymmm> I just saw one AU power meter that was self-powered (thief)
[14:57:19] <ssi> joule thief if I remember correctly is just a little dc/dc converter that's designed to turn batteries into more of a constant power supply
[14:59:57] <Jymmm> Yeah, so says wikipedia too https://en.wikipedia.org/wiki/Joule_thief
[15:00:48] <PCW> marketing name for a boost converter
[15:14:49] <Jymmm> Prebuilt and pricy http://www.brultech.com
[15:15:02] <XXCoder> ssi: it also extracts more power from batteries
[15:15:18] <XXCoder> so you can power stuff off supposely dead battery as long as power requirement is low
[15:16:01] <XXCoder> for little while anyway
[15:17:11] <SpeedEvil> In general, you can extract a percent or so more energy.
[15:17:19] <SpeedEvil> Going from 0.8V-0
[15:18:06] <ssi> XXCoder: only for really naive battery powered devices
[15:21:06] <XXCoder> I suppose
[15:21:14] <XXCoder> it can be useful though
[15:21:50] <XXCoder> Praesmeodymium: I dont think there is any shitty one use camera anymore
[15:22:52] <Praesmeodymium> XXCoder: they sell em in 10 packs
[15:22:58] <XXCoder> lol ok
[15:23:08] <SpeedEvil> http://hackaday.com/2015/06/06/crowdfunding-follies-debunking-the-batteriser/ - related
[15:27:08] <XXCoder> oh look a sock account
[15:30:50] <SpeedEvil> i diddn't read down the comments
[15:31:35] <XXCoder> sometimes great comments and sometimes lol
[15:37:09] <andypugh> Batteriser looks like a reasonable idea over-sold
[15:37:24] <XXCoder> and badly designed
[15:38:05] <andypugh> I haven’t seen one, but a layer of mylar could solve that problem
[15:38:37] <XXCoder> just need wider gap, it only has tiny gap between + and -
[15:38:46] <XXCoder> so it can easily bridge gap
[15:38:49] <XXCoder> and its fire time
[15:39:02] <andypugh> It needs to be tight to fit in standard holders
[15:46:10] <XXCoder> sure but why use metal strip?
[15:46:14] <XXCoder> use plastic or something
[15:46:37] <andypugh> It needs to conduct and be springy and thin.
[15:46:46] <XXCoder> but middle dont need to
[15:47:06] <andypugh> No, and they show it in an Apple keyboard which is made of metal.
[15:48:42] <andypugh> (Actually, I just checked and it is lined with plastic)
[15:48:49] <XXCoder> yeah
[15:52:44] <ssi> PCW: stupid question, in my process data RPC, for bidirectional pins, should it send back the value of the pin before the rpc runs, but leave the pin with the value that was provided over the wire?
[15:52:49] <ssi> seems like the right answer
[15:53:40] <andypugh> Most devices have a read cycle and a write cycle
[15:54:00] <andypugh> So you would send the current value in the read function and set the a
[15:54:05] <JT-Shop> one more hole left on the belt... time for a new one
[15:54:09] <andypugh> value in the write function
[15:54:28] <ssi> andypugh: from my (albeit limited) understanding of smartserial so far, read and write happens concurrently in the pd rpc
[15:54:39] <ssi> pdrpc sends the output bytes over the wire, and the remote returns the input bytes
[15:54:44] <andypugh> JT-Shop: Can’t you probe the hole positions and CNC mill some extra ones at the same spacing?
[15:55:35] <andypugh> ssi: Ah. maybe, I only know anything at all about the link between FPGA and PC.
[15:55:48] <PCW> I depends on how you implement the RPC on the remote
[15:56:11] <JT-Shop> well I've been wearing it for 20-30 years so it is a good excuse for a new one
[15:56:37] <ssi> PCW: I think what I have written is probably a sane way to do it
[15:56:46] <ssi> time will tell :)
[15:57:00] <ssi> I don't know if we even will need bidirectional pins at all
[15:57:05] <ssi> but I'm implementing the framework for them
[15:57:13] <PCW> I think that's easier (hmm wonder what the 7I90 does)
[16:00:34] <PCW> Looks like it dioe's the read first:

[16:06:45] <MacGalempsy> JT-Shop: too big or too small?
[16:25:30] <WZL> hello all,
[16:25:30] <WZL> Can you help me to diagnose something? I got a servo runaway like condition using axis on lcnc 7.1 with a working config
[16:26:53] <WZL> I wrote a loop with a condition : while 1=1 so never ends. Loading the file I noted that axis seem halted, I pres ESC and eventually axis unstuck
[16:27:58] <WZL> I run the program and works as expected in a zig zag fashion . Then I pressed ESC and the program stops but the servo keep going for second and past the expected position for about a meter !!!! It seems that the servo was in control because it decelerated with the expected speed.
[16:29:05] <Deejay> gn8
[16:34:16] <TroyO> Hello, room. Just poking my head in, never knew this was here, LOL.
[16:46:01] <andypugh> WZL: Travelling a meter too far on my machines would be expensive
[16:46:36] <andypugh> WZL: Axis preview hates infinite loops. You can use a comment (AXIS, STOP) to stop the preview.
[16:46:53] <andypugh> WZL: But I see that isn’t your important problem.
[16:47:49] <andypugh> Did the machine follow the programmed path for longer than expected, or wan’t it on the programmed path?
[16:52:33] <WZL> no, the servo simply keep turning as in a continuos jog fashion.
[16:54:06] <WZL> I think that is something related to the TP (in a infinite loop) and the axis jog command
[16:54:08] <Tom_itx> encoder working?
[16:54:24] <Tom_itx> must be if it followed a path
[16:54:54] <WZL> yes, the encoder shows the correct distance
[16:55:23] <andypugh> A broken encoder caused this on a machine last week.
[16:55:40] <andypugh> No following-error trip?
[16:55:52] <andypugh> What is your following-error limit?
[16:56:22] <andypugh> Actually, rewind a bit, was the “correct distance” the commanded distance or the actual distance?
[16:56:57] <WZL> I´m sure that this is a software problem. I can manage to fail it several times
[16:57:28] <WZL> I will try to explain better, sorry about my english
[16:57:33] <andypugh> Well, yes, but, lots of other people use the exact same software, and this isn’t happening to everyone.
[16:59:07] <WZL> ok, the first issue: the infinite loop halt axis on load. it this a right behaviour?
[17:01:32] <WZL> I just noted a new bugfix : ¨LinuxCNC 2.7.2 is out, with an important bugfix in canned cycle preliminary motion¨. this is something related?
[17:01:47] <andypugh> It is not uncommon. Basically Axis makes a trial run through the code to create the preview. You can break the infinite loop in the preview only by use of the “magic comment” that I posted earlier.
[17:02:22] <andypugh> No, that bug-fix only affected the initial move in canned cylcles if your starting point was lower than the R-retract plane.
[17:02:45] <WZL> ok then, second question. how the axis continuos jog works?
[17:04:11] <andypugh> A continuous jog starts as a programmed move to the axis limit. Then when you release the key it is aborted and becomes a controlled stop within machine accel limits. So, if you keep the key pressed the machine stops at the soft limit.
[17:04:26] <andypugh> And, also, if your key-release event is not seen by the system.
[17:04:31] <WZL> I not sure but ir seems related to a continuos jog in a ¨axis stuck ¨ moment
[17:04:38] <andypugh> But you said you were runnign G-code, and that’s very different
[17:04:54] <WZL> yes but is was after the ESC key
[17:05:03] <WZL> the g code works as expected
[17:05:30] <andypugh> Yes, it is possible that Axis might block the GUI so that GUI-commands were not seen. It is rather better to jog with realtime-linked inputs if possible, as they are always serviced.
[17:05:52] <WZL> and I set the axis limit about a km length for testing
[17:06:14] <andypugh> That’s probably not ideal…
[17:06:20] <WZL> ok, I understand
[17:06:45] <WZL> I just testing the electronics but I freak out about this
[17:07:22] <andypugh> If you can connect a jog-wheel to the motion.jog-XXXXX pins then nothing will interfere with them. http://www.linuxcnc.org/docs/html/man/man9/motion.9.html
[17:07:30] <WZL> so if I limit the jog to discrete steps it will safe right?
[17:08:23] <WZL> I thought it worked out that way
[17:08:52] <andypugh> Keyboard jogging and halui jogging is user-space and there is no guarantee that the system will see the key release. (though, normally, this really isn’t a problem, we are typically talking about a few mS delay, not long enough to even notice)
[17:09:44] <WZL> exept when axis is trying to draw a endless loop :)
[17:09:51] <andypugh> After you pressed “ESC” Axis should not have been re-calculating the preview, so I don’t think this is your infinite loop.
[17:10:30] <WZL> so this is not the explanation?
[17:10:31] <andypugh> But, try the (AXIS, STOP) comment at the beginning of the loop.
[17:11:03] <WZL> ok, I will try it tonight
[17:11:39] <andypugh> A keypoard sends a key-press event and a key-release event. Sometimes a bad connection or other issue can mean that the key release event is not seen. I assume you are using a USB keyboard?
[17:12:54] <WZL> yes I do
[17:12:55] <andypugh> See section 11.7 to fix the AXIS preview loop: http://www.linuxcnc.org/docs/html/gui/axis.html#axis:preview-control
[17:14:25] <andypugh> If possible, run a disk space check and memory check on your system. This is the sort of problem that in a different application that wasn’t running a machine would lead to a single key-press typing a whole line of a letter.
[17:15:05] <andypugh> (You would be annoyed, but not in any physical danger, if it was Gedit not LinuxCNC)
[17:16:55] <WZL> if I understad right this problem is because a userspace program commanding a ¨to the axis limit¨ command in a loaded system. right?
[17:18:55] <WZL> in this machine is configured the isolcpus option so I understand that there is only one core available for axis and all the system
[17:19:35] <PCW> IMHO KB jogging is not really safe for big machines (especially wireless or USB KBs)
[17:19:46] <andypugh> No, isolcpus should put LinuxCNC onto the reserved core and everything else on the unreserved one.
[17:20:14] <andypugh> (The isolated CPU core is hidden from the system and does not show up under top)
[17:20:57] <WZL> ok, but I have two cores in total so axis and netflix (just joking) will share the only core left
[17:21:14] <PCW> and unless you really need it, dont use isolcpus as it will slow everything down
[17:21:36] <WZL> KB joggin in discrete steps is safe?
[17:21:47] <PCW> safer for sure
[17:22:43] <WZL> this a test pc only, and isolcpus was confugured as a curiosity
[17:22:56] <andypugh> WZL: Yes. If you want super-reliable jogging then you probably want jogwheels linked to motion.
[17:23:30] <rene-dev_> Im running a big machine without hardware controls, and I find it very challanging to find the axis window while a job is runnign and Im browsing the web :D
[17:23:51] <rene-dev_> altough I do have an esotp of course
[17:24:16] <andypugh> rene-dev_: I have _never_ had that problem, honest :-)
[17:24:34] <WZL> Yes I will limit to use harware jog because the machine is capable of 30 m/min in rapids
[17:24:49] <rene-dev_> PCW: you mean it slows down everything except realtime stuff?
[17:25:26] <andypugh> rene-dev_: Are you using the parport or some more fancy hardware?
[17:26:01] <andypugh> Finding enough parport pins for a jogwheel is probably difficult.
[17:26:03] <rene-dev_> no, 5i25 and 1kw dc servos, but that will be changed to ac servos with my driver soon
[17:26:21] <rene-dev_> actually parport as well, that runs the hydraulics
[17:26:28] <andypugh> Which daugher-boards on the 5i25?
[17:26:48] <rene-dev_> homemade
[17:27:27] <andypugh> Ah, OK. Some of the Mesa daughter-boards support MPG counters on GPIO pins.
[17:27:49] <rene-dev_> i have a usb mpg, but it is shit
[17:28:04] <rene-dev_> and the usb connectiobn dies when the spindle starts
[17:28:30] <ssi> rene-dev_: even with those fancy usb cables that crinq liques?
[17:28:33] <andypugh> And USB has all the problems that we have been discussing
[17:28:34] <ssi> er, likes lol
[17:28:51] <rene-dev_> I know, but someone gave it to me...
[17:29:00] <rene-dev_> now I know why
[17:29:29] <rene-dev_> ssi: it does not have microusb
[17:29:33] <andypugh> If the USB dies when the spindle starts, other things may well have problems too.
[17:29:34] <ssi> ah
[17:29:45] <WZL> a related question , all the ethernet developments run in userspace? are safe?
[17:29:56] <andypugh> If the spindle in on a VFD then you might want a mains input filter for it.
[17:30:34] <andypugh> The uspace ethernet drivers still run in realtime, but they are user-space realtime not kernel module realtime.
[17:30:44] <WZL> ok
[17:31:07] <rene-dev_> I have 3 spindles... 2 of them on a vfd
[17:31:25] <andypugh> (I am actually being a bit ambigious when talking abouit realtime and userpsace as the two parts of the system, it is really realtime and non-realtime)
[17:31:55] <rene-dev_> I had to disable the filter, it kills the rcd, which is unfortunateley out of my control
[17:32:25] <andypugh> rene-dev_: You can get 3mA filters. Most are 30mA leakage and will trip an RCD.
[17:32:45] <R2E4_> evening all
[17:32:55] <rene-dev_> I have one in the cabinet which does not kill it, but the one in the vfd trips it
[17:33:10] <rene-dev_> but the vfd is too large for the cabinet
[17:33:24] <rene-dev_> I have l larger one, but no time yet to change all teh wires
[17:35:05] <andypugh> This one, for example, says that it is 7mA http://www.ebay.co.uk/itm/Rasmi-single-Phase-RFI-Filter-/331680015566?hash=item4d39ab64ce:g:mWcAAOSw9N1VoqKk
[17:35:49] <rene-dev_> I think I have the exact same one, but 3 phase and 20A installed
[17:35:56] <andypugh> If you have a 30mA ot 10mA RCD then that one might be OK.
[17:36:18] <andypugh> RCD and 3-phase is a bit of an unusual combination isn’t it?
[17:36:19] <Tom_itx> aren't those just chokes with some caps on em?
[17:36:29] <rene-dev_> no?
[17:36:43] <andypugh> Tom_itx: Well, yes, but packaged to do a job.
[17:37:05] <Tom_itx> i suppose prepackaged is good
[17:37:57] <andypugh> They have handy terminals and are set up with the right layout and component values to do the job. And they are pretty cheap.
[17:38:50] <WZL> rene-dev_: you can´t simply isolate the filter from ground to retain the in-line choke filter and avoid to disable the whole filter?
[17:39:23] <andypugh> The ones I have use GND as part of the filter network
[17:39:33] <andypugh> (Which is why they leak and trip RCDs)
[17:40:35] <rene-dev_> I dont know, what happens, there is a parameter in the vfd to disable the filter, and that helps
[17:45:47] <andypugh> First pattern just about ready for the foundry: https://picasaweb.google.com/lh/photo/mhMpBdyDtruxnFY9zyu149MTjNZETYmyPJy0liipFm0?feat=directlink
[17:46:51] <JT-Shop> looking good andypugh
[17:47:05] <andypugh> Still need to finish the core boxes. And make 3 more core-boxes and 2 more patterns. And I am starting to get bored of it.
[17:47:06] <CaptHindsight> that's a good size hunk of metal
[17:47:18] <Tom_itx> yeah, what's it supposed to be?
[17:47:30] <andypugh> It’s a lathe feeds gearbox
[17:47:58] <CaptHindsight> cast iron vs polymer granite
[17:47:59] <JT-Shop> is that special paint?
[17:48:01] <Tom_itx> i bet your local foundry loves you
[17:48:37] <andypugh> The foundry quoted £80 for that part. But he hasn’t seen it yet :-)
[17:48:39] <WZL> this is the feeds? it´s a BIG lathe
[17:48:45] <Tom_itx> hah
[17:49:12] <CaptHindsight> maybe add a 0
[17:49:30] <andypugh> WZL: Not super-big. The casting is the motor mount in this part-finished model: https://picasaweb.google.com/lh/photo/t30w7IzwpLdSNfPFP6orwNMTjNZETYmyPJy0liipFm0?feat=directlink
[17:50:09] <CaptHindsight> for casting they are pretty reasonable around here, it's the patterns they like to stick it to you
[17:50:17] <andypugh> CaptHindsight: Nah. I am expecting that it might be £120 bit no more.
[17:50:40] <andypugh> I can see why, there is a lot more work in the patterns than the casting.
[17:51:20] <CaptHindsight> plus that is hollow
[17:51:55] <andypugh> Yes, 10mm wall thickness, so only about 20kg of metal.
[17:52:30] <WZL> this is the inner core?
[17:54:02] <andypugh> WZL: This is tge same pattern, unpainted, and the core-boxes: https://picasaweb.google.com/lh/photo/T6Ks0gmDHhdQE3IiTMoFAdMTjNZETYmyPJy0liipFm0?feat=directlink
[17:55:02] <andypugh> So, the core boxes ar clamped together to make a sand core, then that becomes the air-space in the final casting.
[17:55:09] <WZL> nice
[17:56:29] <andypugh> But as my mill has a 1000rpm spindle each core box half was a full day of machining, and another day to make the blank, then the painting, sanding, painting some more. Thoroughly bored now.
[17:57:14] <Tom_itx> did you do both halves in fusion?
[17:57:20] <andypugh> Yes
[17:57:26] <WZL> this is a job for a router. I only think about the dust
[17:57:27] <Tom_itx> as a single unit the split them?
[17:57:35] <Tom_itx> then*
[17:57:49] <andypugh> Well, I actually did it in Inventor, but the idea is the same
[17:58:04] <Tom_itx> yeah, just curious how you went about it
[17:58:19] <Tom_itx> draw the part as a solid then use the outside instead of the part as the part?
[17:58:29] <andypugh> Make the pattern from the model as a derived part with a 1.01 scale for shrinkage
[17:58:47] <Tom_itx> is that a standard shrinkage value?
[17:59:01] <andypugh> Yes
[18:00:24] <andypugh> Then create another new part for the core box, and derive the pattern into that as a solid. Then subtract the main pattern from another extrusion with a boolean subtract to get the core shape as single lump
[18:00:28] <Tom_itx> https://plus.google.com/photos/108164504656404380542/albums/6154759290444673793/6209656347812210930?pid=6209656347812210930&oid=108164504656404380542
[18:00:35] <Tom_itx> so that is foam? looks like wood
[18:00:53] <CaptHindsight> anyone have personal experience with an Everlast TIG?
[18:01:01] <CaptHindsight> http://www.everlastgenerators.com/product/tig-stick/powertig-250ex
[18:01:04] <Jymmm> home depot tig?
[18:01:08] <andypugh> It is wood. Well, a stack of MDF glued together
[18:01:36] <Jymmm> cant see it
[18:01:44] <CaptHindsight> Jymmm: no, a real TIG, just not a red or blue
[18:01:47] <andypugh> Foam would be better, it needs a lot less sanding and painting, but a lump that size would be >£100
[18:02:33] <Tom_itx> did you machine relief in the walls for mold release?
[18:02:38] <Tom_itx> draft angle
[18:02:45] <Tom_itx> looks like it
[18:02:49] <andypugh> Yes. Inventor has tools to add draft to faces.
[18:04:16] <andypugh> These patterns are model-board (PU foam) https://picasaweb.google.com/lh/photo/SPQQ70I_GFJ98Zec9LHmhtMTjNZETYmyPJy0liipFm0?feat=directlink
[18:04:53] <WZL> good night guys, I will go home. Thanks for your help.
[18:04:56] <andypugh> Much cleaner and nicer to work with, but the lumps I found in the skip at work were not big enough for the big patterns. :-)
[18:10:10] <Sync> CaptHindsight: it is overpriced, but in general, I have nothing bad to say about them
[18:12:34] <Tom_itx> andypugh are you running 2.7 on your mill?
[18:12:51] <andypugh> I don’t think I am
[18:16:21] <PetefromTn_> Hey folks
[18:16:36] <PetefromTn_> hows it going today in linuxCNC land
[18:17:07] <Tom_itx> fair to partly cloudy
[18:17:10] <PetefromTn_> I have been looking over the manuals for the DMM servo drives
[18:17:22] <PetefromTn_> it was beautiful here today actually
[18:17:34] <PetefromTn_> anyway
[18:17:40] <PetefromTn_> there is a lot of good news
[18:17:59] <Tom_itx> you decided to send em to me?
[18:18:02] <PetefromTn_> first the motors seem to be a bolt in replacement for my old motors IE to the mounts etc.
[18:18:08] <PetefromTn_> no heh
[18:18:15] <Tom_itx> well damn
[18:18:51] <PetefromTn_> unforunately the drive pullies are the wrong size but they are the type of pulley that you can replace the middle insert in so I will just have to order the inserts in the correct size
[18:19:06] <PetefromTn_> or just order the correct size pullies
[18:19:37] <PetefromTn_> the other great news is that the drives manual seems to say that the main IO connector that will be wired into the 7i77 card
[18:19:45] <PetefromTn_> uses a Dsub 25 pin connector
[18:19:52] <PetefromTn_> so unlike the TECO's
[18:20:14] <PetefromTn_> which used some unusual sized japan spec connector that I had to individually solder
[18:20:29] <PetefromTn_> each wire to and build that connector cable
[18:20:51] <PetefromTn_> I SHOULD just be able to grab any old DB25 cable and cut one end off
[18:21:00] <PetefromTn_> and wire appropriately
[18:21:12] <PetefromTn_> which will save me a boatload of work
[18:21:39] <PetefromTn_> The motors look very nice as do the DYN4 drives
[18:21:58] <PetefromTn_> the premade cables look just like the ones I got with the TECO's
[18:22:18] <PetefromTn_> with the exception that the TECO motors being much larger and higher power used barrel connector plugs
[18:22:43] <Sync> hmm the dyn4 look like old yaskawas
[18:22:49] <PetefromTn_> whereas these motors are only 750 watt Nema 34s and don't have those types of connectors
[18:22:49] <jthornton> not all DB25 cables are made the same... some leave wires out
[18:23:00] <PetefromTn_> jthornton yup
[18:23:14] <PetefromTn_> I will make sure I use the right one ;)
[18:23:42] <PetefromTn_> my friend Art and I were looking over the system and discussing options
[18:23:50] * jthornton is making Korean Shrimp Pancakes tonight yum
[18:24:35] <PetefromTn_> the idea of using the din rail mounted 24v and 5v power supplies like R2E4 as well as using the picopc 24v DC PC power supply should make hooking everything up a piece of cake
[18:24:44] <PetefromTn_> more good news
[18:25:00] <PetefromTn_> is the machine came with some nice components I need back there already
[18:25:08] <PetefromTn_> such as a bank of relays
[18:25:26] <PetefromTn_> and a large telemechanique contactor that appears to be perfect for the application
[18:25:39] <jthornton> sweet
[18:25:57] <PetefromTn_> also the machine electronics enclosure has to large pancake fans in there
[18:26:36] <PetefromTn_> the spindle encoder is built in as well and other than having to extend the wires where some jackhole got happy with a wire cutter in the enclosure should just hook right up to the 7i77
[18:26:53] <PetefromTn_> so at this point I am making a list of items I need
[18:27:12] <PetefromTn_> I am going to probably go with that Asroc main board we were talking about last night
[18:27:31] <PetefromTn_> whichever SDD is reasonable and of good review
[18:27:49] <PetefromTn_> probably going to get the two 8G DMM ram modules
[18:28:32] <PetefromTn_> I need to figure out which picopc 24v power supply will work best apparenlty the main board typically uses at most 40 watts
[18:28:42] <jthornton> I just ordered another gigabyte motherboard I was so impressed with the latency of the first one
[18:28:46] <PetefromTn_> but most of them are 20 pin not 24 pin
[18:28:59] <PetefromTn_> so it sounded like connor had a cable solution for that
[18:29:15] <PetefromTn_> which gigabyte board did you get?
[18:29:29] <jthornton> getting links
[18:29:39] <andypugh> 16GB RAM seems excessive for a LinuxCNC machine
[18:29:41] <jthornton> http://linuxcnc.org/index.php/english/forum/18-computer/29147-intel-cpu-on-board-motherboard-suggestion?start=20
[18:29:49] <jthornton> http://www.newegg.com/Product/Product.aspx?Item=N82E16813128860&Tpk=13-128-860
[18:29:53] <PetefromTn_> andypugh well I agree
[18:29:56] <jthornton> http://www.newegg.com/Product/Product.aspx?Item=N82E16819117545&Tpk=19-117-545
[18:30:03] <jthornton> http://www.newegg.com/Product/Product.aspx?Item=N82E16820231718&Tpk=20-231-718
[18:30:07] <PetefromTn_> but apparently you need to populate the board with two ram modules
[18:30:16] <PetefromTn_> and the 8 gig are only like 40 bucks
[18:30:27] <PetefromTn_> and I cannot imagine a 4 gig would be much less
[18:30:30] <jthornton> I don't recommend the case I bought the power supply only had one sata plug
[18:30:39] <andypugh> I like to use motherboards that take 12V input.
[18:32:03] <PetefromTn_> jthornton so you have this board and have experienced excellent performance and latency
[18:32:24] <PetefromTn_> andypugh I plan to use the picopc power supply with 24v input
[18:32:47] <PetefromTn_> going to probably use a 120w 24v dc DIN rail mounted power supply
[18:33:02] <PetefromTn_> this is all tentative
[18:33:12] <PetefromTn_> if you guys see anything wrong with any of this speak now
[18:33:16] <andypugh> I have used PicoPSU, but some boards take 12V (or 24V) directly
[18:33:25] <PetefromTn_> yes
[18:33:40] <PetefromTn_> but I won't have a 12vdc power supply to run them
[18:35:16] <PetefromTn_> so you have like $140 into that board/cpu
[18:35:43] <andypugh> In recent machines I have uesed one big 24V supply and a bunch of these for 5V and 12V: http://www.ebay.co.uk/itm/DC-DC-LM2596-Voltage-Regulator-Step-Down-Converter-Buck-Led-Voltmeter-Module-/261760407823?hash=item3cf222d90f:g:w44AAOSwv0tU-Ce4
[18:36:10] <andypugh> (Pretty led displays mean you can look in the back and be sure that the voltages are all there)
[18:36:16] <PetefromTn_> how big was the power supply
[18:36:51] <PetefromTn_> that's pretty cool BTW
[18:37:11] <andypugh> Well, I got a bargain so the one in the Mill is a crazy 500W one.
[18:37:12] <PetefromTn_> wonder if they make that in a DIN rail mount
[18:37:30] <PetefromTn_> that is crazy unless your drives are DV
[18:37:32] <PetefromTn_> DC
[18:37:43] <PetefromTn_> motors rather
[18:37:45] <andypugh> It does run the A-axis servo, too.
[18:38:13] <PetefromTn_> honestly if I got two of those converters you linked to
[18:38:16] <jthornton> PetefromTn_, yes I have one and one on the way
[18:38:20] <PetefromTn_> it would actually save me some cash
[18:38:35] <PetefromTn_> because the 5v power supply I was going to get is like $45
[18:38:39] <PetefromTn_> DIN rail mount
[18:39:01] <PetefromTn_> if I got the LARGER 240 watt power supply
[18:39:09] <PetefromTn_> it is like 115 bucks
[18:39:23] <PetefromTn_> plus whatever those are in US bucks LOL
[18:39:33] <andypugh> I just put the boards on DIN-adapters: http://www.ebay.co.uk/itm/10-Sets-DIN-Rail-Mounting-Adapters-Feet-for-35mm-32mm-or-15mm-DIN-rail-/371475699457?hash=item567dad5701:m:mo4RMVkdj9XGcw1dtASuDAA
[18:40:09] <PetefromTn_> ooh those are cool
[18:41:00] <PetefromTn_> that ram is cool and a good bit cheaper
[18:41:28] <PetefromTn_> well actually it is the same price ;)
[18:41:42] <PetefromTn_> but I could buy two of those for 8G total
[18:41:52] <PetefromTn_> and be at the price of one 8g single stick
[18:42:05] <PetefromTn_> so that works and is as said more than adequate
[18:42:34] <PetefromTn_> Tom seemed to get good latency from this asroc board apparently
[18:43:17] <PetefromTn_> I can't tell you how happy I am that I might not have to solder those high density connectors LOL
[18:43:42] <PetefromTn_> andypugh what do you use for your AC distribution
[18:44:39] <andypugh> Incidentally, that eBay proce for the brackets isn’t super-competitive compared to even Digikey: http://www.digikey.com/product-search/en?keywords=1201578
[18:44:51] <PetefromTn_> I figured as much
[18:45:19] <PetefromTn_> wonder if those would work for the mesa cards
[18:45:26] <andypugh> I don’t tend to have much AC distribution.
[18:45:47] <PetefromTn_> I don't remember if I got the din mount kit or not I gotta look
[18:45:52] <PetefromTn_> really?
[18:46:06] <PetefromTn_> that was a bit of a challenge on the Cincinatti
[18:46:12] <andypugh> http://store.mesanet.com/index.php?route=product/product&filter_name=DIN&product_id=227
[18:46:30] <andypugh> Mesa adaptors are not super-expensive either.
[18:46:40] <PetefromTn_> yeah that is what I used in the cincinatti
[18:46:43] <PetefromTn_> worked great
[18:46:57] <PetefromTn_> I would love to use as much din rail stuff as possible
[18:47:14] <PetefromTn_> there is a good bit of rail inside the electronics enclosure
[18:47:26] <andypugh> To take AC power into my drive PSU I used Neutrik PowerCON.
[18:47:55] <PetefromTn_> drive psu?
[18:47:58] <andypugh> (Those are my connector of choice for AC and motor-3-phase)
[18:48:25] <andypugh> Yeah, box of caps and regulator to make the 300V DC for the servo drives.
[18:48:45] <PetefromTn_> aah ok
[18:48:59] <PetefromTn_> these drives all take direct AC input
[18:49:04] <PetefromTn_> just like on the Cincinatti
[18:49:27] <PetefromTn_> but there will be much less stuff in this machine
[18:49:44] <PetefromTn_> I had to power the 3 phase vfd for the coolant pump in the Cinci
[18:49:55] <PetefromTn_> this machine came without a coolant pump for the built in sump
[18:50:21] <PetefromTn_> so I will just buy whatever 120v AC pump I can get that is suitable for a reasonable price and hit it with a relay
[18:50:55] <PetefromTn_> there is even an AC relay in there already which might work for that
[18:51:03] <andypugh> You probably don’t need them in that case, but these are PowerCON: http://www.ebay.com/sch/i.html?_from=R40&_trksid=p2050601.m570.l1313.TR12.TRC2.A0.H0.XpowerCON.TRS0&_nkw=powerCON&_sacat=0
[18:51:36] <PetefromTn_> Oh no I know those that is not what I was talking about
[18:51:38] <andypugh> They do a 4-pole for speakers that works nicely for steppers or 3-phase motors. 250V 40A rating…
[18:51:52] <PetefromTn_> I am talking about DIN mounted power distribution blocks
[18:52:12] <andypugh> Ah, right, I just use normal blocks.
[18:52:15] <PetefromTn_> like bring in big AC cables in top and break out into smaller ones to the contactors etc.
[18:52:36] <andypugh> It helps when you realise that they can be bussed together, that is what the screw in the top is for.
[18:52:50] <PetefromTn_> yeah that is nice
[18:53:08] <PetefromTn_> all of these things make this stuff super easy
[18:53:39] <andypugh> Though actually getting the bus-strips for the blocks can be difficult
[18:54:08] <PetefromTn_> I got mine from Galco
[18:54:16] <PetefromTn_> trying to login there so I can see what I got
[18:55:24] <andypugh> It isn’t super-easy to see, but the terminal blocks on the right hand panel here are bussed together for GND, 5V 12V and 24V: https://picasaweb.google.com/lh/photo/fU5J9IOTdl79f8fkCVs5NtMTjNZETYmyPJy0liipFm0?feat=directlink
[18:57:19] <PetefromTn_> nice..
[18:57:31] <PetefromTn_> bb in a bit gotta eat dinner thanks guys
[18:58:56] <Tom_itx> andypugh, i use those buck regs too and after i have it set, i put a dot of hotglue on the pot so vibration doesn't decide to change it
[18:59:14] <andypugh> Probably wise.
[18:59:31] <Tom_itx> it comes off easy if you need to adjust something too
[19:00:28] <Tom_itx> you can't build em for that price
[19:01:42] <Tom_itx> these are the preset ver of the same chip but cost ~$10 to make: http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/5v_switcher.jpg
[19:01:59] <andypugh> On reflection, for power distribution I reckon these make more sense than bussing together terminal blocks: http://uk.rs-online.com/web/p/commoning-blocks/3882833/
[19:02:46] <Tom_itx> i used some pcw has on the site for all my 5v stuff
[19:03:42] <Tom_itx> instead of daisychaining the supply wire i brought each one back to the header
[19:07:40] <andypugh> The Mesa commoning block looks pretty neat, actually. Though it might be easier to make one that wait for Mesa.
[19:08:01] <PCW> we have a little 8-45V to 5V 2A buck converter also (LBUCK) But I have not got around to putting it on the website
[19:08:15] <zeeshan> for encoder powering?
[19:08:35] <PCW> yeah +24 to local 5V kind of stuff
[19:08:44] <zeeshan> hm that would be nice
[19:08:46] <zeeshan> if its din rail mounted
[19:08:55] <zeeshan> i have a dedicated supply for 5v and 24v
[19:09:00] <zeeshan> it'd be nice to collapse it into 1
[19:09:08] <PCW> its tiny (1.5x1.5)
[19:09:19] <zeeshan> nice
[19:09:31] <Sync> zeeshan: just use on of those 1/8 or 1/16 bricks
[19:09:48] <PCW> terminal block in/out 3.3v/5V jumper
[19:10:04] <PCW> no electrolytics
[19:12:27] <Sync> http://www.digikey.de/product-detail/de/APXW003A0X3-SRZ/555-1245-1-ND/2640013 I use these in a product
[19:12:30] <Sync> they are awesome
[19:12:50] <zeeshan> no din rail mount
[19:13:19] <ssi> it's a component :P
[19:13:33] <zeeshan> shrug
[19:13:38] <zeeshan> at eaton everything is din rail mount
[19:13:39] <zeeshan> :P
[19:13:43] <zeeshan> even small dinky circuits
[19:13:52] <zeeshan> makes life easy
[19:14:16] <ssi> "at eaton, even when we buy surface mount resistors they're din mount. I really have no clue how they even manage to build anything"
[19:14:35] <malcom2073> Lol
[19:14:38] <zeeshan> they wouldn't design something that needed an external resistor
[19:14:41] <zeeshan> unless its a massive one
[19:14:41] <malcom2073> That's awesome
[19:14:41] <ssi> "last week we bought a bunch of copper bus bar to make 1600000A circuit panels, and for some reason the raw copper stock was din mount"
[19:15:14] <malcom2073> They don't design anything cool then, some of the coolest stuff needs external resistors
[19:15:37] <zeeshan> read above
[19:15:49] <ssi> "it was pretty cool really, we just went around all day picking shit up off the floor and snapping it onto din rail for no reason. My buddy found a potato chip that some ants were carrying off and it had a damn din mount on it, so we stuck it on the wall"
[19:15:53] <CaptHindsight> 1600000 W internal DIN mount resistor
[19:16:08] <zeeshan> dude
[19:16:11] <malcom2073> Lol
[19:16:13] <zeeshan> today i had designed something
[19:16:17] <zeeshan> and it wasn't to standard lol
[19:16:19] <malcom2073> Was it DIN rail mountable?
[19:16:25] <zeeshan> i got edumuacted
[19:16:31] <zeeshan> apparently 250mcm cable
[19:16:38] <zeeshan> needs support every 6"
[19:16:44] <malcom2073> din support?
[19:16:48] <zeeshan> no
[19:16:51] <zeeshan> we're using gp03
[19:16:53] <ssi> malcom2073: ^5
[19:17:05] <SpeedEvil> I am confused by the unit mcm
[19:17:13] <ssi> millicentimeter, duh
[19:17:21] <zeeshan> kcmil
[19:17:23] <zeeshan> same thing
[19:17:28] <malcom2073> mcm == din rail cm
[19:17:38] <malcom2073> because in german, din starts with a m
[19:17:43] <SpeedEvil> ah
[19:17:44] <ssi> god that's a bastardization unit if I've ever seen one
[19:17:57] <zeeshan> yea its a bit annoying
[19:18:00] <zeeshan> but it started with awg :P
[19:18:01] <ssi> cmil is a bastard unit to begin with
[19:18:23] * ssi likes millicentimeter better
[19:18:30] <zeeshan> its like any other conversion though
[19:18:34] <zeeshan> just remember A = d^2
[19:18:45] <zeeshan> very easy to convert to a real unit like cm or inch
[19:19:12] <ssi> yeah except d^2 is part of what makes it bastard unit to begin with
[19:19:23] <SpeedEvil> decibels annoys me more.
[19:19:23] <ssi> cmil is the area that the conductor would have if it were a square with side length equal to diameter
[19:19:27] <ssi> or some bullshit like that
[19:19:30] <zeeshan> its really not much diff than dealin with F
[19:19:32] <zeeshan> for example :P
[19:19:38] <SpeedEvil> the calculation varies if it's a 'power-like' or a 'scalar-like' value
[19:19:43] <malcom2073> ssi: That sounds like "We're too lazy to remember pi*r^2
[19:19:44] <malcom2073> "
[19:19:49] <ssi> malcom2073: that's exactly what it is
[19:19:53] <malcom2073> Bwaha
[19:19:59] <ssi> it's a relative unit, so the absolute number doesn't matter
[19:20:00] <CaptHindsight> cubic fortnights
[19:20:01] <malcom2073> That's fantastic
[19:20:03] <ssi> and d^2 is faster
[19:20:11] <zeeshan> SpeedEvil: its just log scale
[19:20:13] <ssi> it's almost a dimensionless unit, but not quite :P
[19:20:26] <SpeedEvil> zeeshan: But it's a _different_ log scale for power and scalar-like
[19:20:36] <ssi> SpeedEvil: that's just cause ohm's law
[19:20:52] <zeeshan> are you talking about noise
[19:20:53] <ssi> power is nonlinear
[19:20:54] <zeeshan> or electricity
[19:20:58] <SpeedEvil> ssi: no, it's not
[19:21:53] <SpeedEvil> 10dBV/0dBV is not the same as 10dBW/0dBW
[19:22:10] <SpeedEvil> you need to know what the unit means before you can compute the decibels
[19:22:11] <ssi> well for starters dBV and dBW are referenced to a different baseline
[19:22:22] <zeeshan> SpeedEvil: baseline
[19:22:23] <zeeshan> er
[19:22:42] <PetefromTn_> Man I can't wait to see this CNC lathe make some parts ;)
[19:22:50] <SpeedEvil> you can't just treat 'V' as an irrelevant part of the unit, like 'mV' - you know 'mV' will be 1/1000th of a V
[19:22:58] <ssi> no, you can't
[19:23:03] <ssi> they're different units
[19:23:04] <zeeshan> its a log scale!!!!1
[19:23:07] <zeeshan> its not linear
[19:23:18] <SpeedEvil> I'm not expecting it to be linear
[19:23:43] <zeeshan> im too dumb to understand your complaint then :P
[19:24:33] <zeeshan> http://c2.staticflickr.com/8/7480/16082519967_8e2e4ad967_h.jpg
[19:24:37] <ssi> zeeshan: power into a load is related to the square of voltage into a load because of ohms law
[19:24:42] <zeeshan> 5v supply is definitely a lloot bigger than 1.5"x1.5"
[19:24:49] <SpeedEvil> decibel is explicitly a power ratio.
[19:24:50] <zeeshan> i could fit it on the din rail above
[19:24:56] <PetefromTn_> andypugh that electronics cabinet you linked to what machine is that for?
[19:24:56] <ssi> zeeshan: so when you work with power ratios it's 10log, and when you work with amplitudes it's 20log
[19:25:17] <zeeshan> that makes sense
[19:25:58] <PetefromTn_> what do you guys think of the idea of that 24v to 12 and 5v converter board? Looks interesting no?
[19:26:02] <ssi> so 20 dBV == 10 dBW
[19:26:04] <SpeedEvil> This means that a 10dB increase means different things depending on if the unit (dBV, dBW) is power-like or not.
[19:28:15] <zeeshan> PetefromTn_: honestly man
[19:28:20] <zeeshan> i like the converter idea
[19:28:28] <zeeshan> but having a dedicated supply is more robust obviously
[19:28:35] <zeeshan> thats why i think ill stick to a 5v and 24v supply
[19:28:56] <zeeshan> like its $20-30 a supply
[19:28:58] <zeeshan> its worth it
[19:29:35] <zeeshan> im going to have trouble fitting the drives and stuff for this machine
[19:29:49] <zeeshan> i need a large ass vfd for the spindle, one large ass one for the hydraulic unit
[19:30:45] <zeeshan> i thinking of using a 48x48" cabinet for all the power distribution, relays, vfds, drives, etc
[19:31:09] <zeeshan> and since the machine has a box where the old fanuc 3t control went, throw all the computer related stuff there, including mesa
[19:31:45] <zeeshan> i wonder if my work will let me order a custom box
[19:33:11] <PetefromTn_> zeeshan actually man the electronics cabinet on this machine is rather massive considering what will be going inside it.
[19:33:20] <zeeshan> what size is it?
[19:33:25] <PetefromTn_> I could probably build everything into a box a quarter of the size
[19:33:30] <PetefromTn_> maybe less
[19:33:40] <PetefromTn_> I dunno I have not measured it
[19:34:22] <PetefromTn_> but I would guess it is probably five by six foot and maybe 18" deep
[19:34:35] <zeeshan> jeez
[19:34:37] <zeeshan> you should snap some pics
[19:34:42] <zeeshan> is there nothing in it right now?
[19:34:47] <PetefromTn_> Oh I will probably do that
[19:35:00] <PetefromTn_> no it has all the din rails and some cable guide stuff
[19:35:10] <PetefromTn_> it has a couple relays
[19:35:17] <PetefromTn_> a large transformer
[19:35:28] <PetefromTn_> a bank of circuit breakers din rail
[19:35:40] <PetefromTn_> a main contactor/switch
[19:35:50] <PetefromTn_> a pair of good sized pancake fans
[19:36:04] <PetefromTn_> and some other odds and ends din rail stiff
[19:36:05] <PetefromTn_> stuff
[19:36:32] <PetefromTn_> It is pretty dusty in there tho I will have to probably clean the crap out of it before I start installing stuff
[19:36:44] <PetefromTn_> I was trying to decide what to do about mounting the PC stuff
[19:37:12] <PetefromTn_> I am planning to build a large rectangular pendant for the front of the machine to house the monitor and keyboard/switches etc.
[19:37:24] <PetefromTn_> it did not come with one unfortunately
[19:37:39] <PetefromTn_> but honestly after seeing pictures of what It would have come with
[19:37:53] <PetefromTn_> it looked like a bigass metal TRS80 computer on a stick
[19:38:09] <PetefromTn_> I think I would be happier making something for it anyways
[19:39:23] <PetefromTn_> I have some heavy gauge hot roll sheet here that would be perfect for building the box.
[19:39:35] <PetefromTn_> My only question right now is where I will put the PC
[19:39:52] <PetefromTn_> in the Cincinatti I built the PC into the pendant at the front of the machine
[19:40:10] <PetefromTn_> and I ran 120vac up there to a terminal box to power the Pc and the monitor
[19:40:27] <PetefromTn_> but this PC will be run on the 24vdc from the power supply
[19:40:39] <PetefromTn_> so it MIGHT be better to leave it out back
[19:40:56] <PetefromTn_> but then you deal with longish cables for the monitor and keyboard etc..
[19:41:08] <PetefromTn_> so I am undecided on where to put it
[19:42:42] <zeeshan> i think isolating it in the pendant is a good idea
[19:42:56] <zeeshan> but i havent had much problems with mine being in the power distribution area
[19:43:07] <zeeshan> 60hz doesnt really do anything for noise
[19:43:11] <PetefromTn_> I know a lot of people put it back there without issue
[19:43:22] <zeeshan> im glad i kept my vfds in a seperate box
[19:43:28] <zeeshan> those are noisy bastards
[19:43:48] <PetefromTn_> I wouldn't think putting it up front would be a problem for the DC power setup it is not very far after all
[19:44:03] <zeeshan> why dont you wanna use a dedicated power supply for your pc
[19:44:05] <zeeshan> like the standard ones
[19:44:32] <zeeshan> the main thing wrong with my setup
[19:44:36] <PetefromTn_> I honestly don't mind that
[19:44:44] <zeeshan> is ran a 25ft cable for vga
[19:44:48] <zeeshan> and i get lines on my screen
[19:44:52] <zeeshan> i need to do something about that..
[19:44:52] <PetefromTn_> but Tom said he liked the picopc stuff
[19:45:01] <zeeshan> ive heard you can use dvi
[19:45:05] <zeeshan> or a vga booster
[19:45:15] <PetefromTn_> and it would negate the need for a custom mounting for a typical power supply
[19:45:35] <PetefromTn_> because it basically plugs into the board
[19:45:43] <zeeshan> oh i see it now
[19:45:45] <zeeshan> that is nice
[19:46:00] <zeeshan> for some reason im annoyed with having walwarts inside the enclosure
[19:46:11] <zeeshan> can you give that dc jack 24v
[19:46:12] <zeeshan> direct?
[19:46:30] <PetefromTn_> yeah it is capable of like 12-36v
[19:46:37] <zeeshan> ncie!
[19:46:40] <PetefromTn_> or something like that
[19:46:54] <zeeshan> its about the same price as a regular psu
[19:46:55] <PetefromTn_> I figure this PC will take around 40 watts or so
[19:47:03] <PetefromTn_> yeah it looks nice man I think
[19:47:11] <PetefromTn_> and would simplify the build a good bit
[19:47:59] <zeeshan> they're patented
[19:48:02] <zeeshan> so you know they gotta be good
[19:48:03] <PetefromTn_> I figure I will put the Hitachi WJ200 way down low in the enclosure because the power to the main motor is down there and close
[19:48:07] <zeeshan> someone spent thousands trying to patent it
[19:48:09] <zeeshan> so they care
[19:48:16] <PetefromTn_> yeah thats good
[19:48:32] <PetefromTn_> I will put the servo drives somewhere in the middle
[19:48:35] <zeeshan> dude this is going to make things really nice
[19:48:43] <PetefromTn_> close to wherever the leads need to go
[19:48:47] <zeeshan> ill keep a 24v din-terminal block in the pendant area
[19:48:55] <zeeshan> and distribute power to this thing and my buttns and things like that
[19:49:14] <PetefromTn_> yeah 24v scheme is the way to go for a lot of reasons
[19:49:26] <zeeshan> its completely prone to noise
[19:49:28] <zeeshan> from my exp
[19:49:28] <PetefromTn_> I just was not aware you could even use it to power the PC
[19:49:34] <PetefromTn_> yup
[19:49:43] <Jymmm> zeeshan: Just remember to twist the black white green and red wires together!
[19:49:51] <PetefromTn_> too bad you can't run the monitor that way hmm
[19:49:56] <zeeshan> you can!
[19:49:57] <Jymmm> zeeshan: BUT NOT THE BLUE ONE
[19:50:00] <zeeshan> i run my monitor from 12vdc
[19:50:01] <zeeshan> haha
[19:50:07] <duc> Any preference of torque or speed reference for controlling servo
[19:50:09] <PetefromTn_> oh yeah?
[19:50:19] <Jymmm> duc: RAMMING SPEED!!!!
[19:50:21] <zeeshan> i take one of the regular psu connectors and power it directly with 12vdc
[19:50:26] <zeeshan> so basically whwnever you turn on your comp
[19:50:28] <zeeshan> the monitor turns on by itself
[19:50:41] <PetefromTn_> duc I run mine on speed but PCW said torque is more precise somehow
[19:51:03] <PetefromTn_> as far as controlling the torque curves but that is beyond me
[19:51:27] <PetefromTn_> how many watts you figure for the monitor?
[19:51:47] <duc> Until the 3 yaskawa 750w motors and sgdv drives, I would start making notes about wiring
[19:51:51] <PCW> Velocity mode is easier to tune and more suited to normal LinuxCNC update rates
[19:51:53] <PCW> Torque mode is good for things like Z axis where you can balance gravity loads
[19:52:09] <PetefromTn_> ^^
[19:52:36] <PCW> but torque mode typically requires faster servo thread rates (say 2- 8 KHz)
[19:52:44] <zeeshan> wouildnt torque mode
[19:52:49] <zeeshan> get rid of stick and sliip issues
[19:53:09] <PCW> (since in this case LinuxCNC needs to run the velocity loop)
[19:53:26] <duc> Controller with be a 5i25/7i77 card setup
[19:53:38] <PetefromTn_> good choice ;)
[19:53:59] <PCW> you can try both, velocity mode is typically easier to tune
[19:54:15] <duc> Baby steps it is
[19:54:34] <duc> Is there a trade in credit for a 7i76 card. Lol
[19:54:37] <PetefromTn_> is it possible to run BOTH on one machine?
[19:55:12] <Sync> velocity and torque?
[19:55:20] <PetefromTn_> yeah
[19:55:43] <PetefromTn_> IE one drive Vel the other torque
[19:56:18] <Sync> I don't see why not
[19:58:30] <Tom_itx> damn i hate when suttle programming errors show up 6mo after you write the code and forgot what you had in mind...
[19:59:02] <PetefromTn_> jeez man I wish I could use that sumitomo drive on my lathe zeeshan it would save me a bunch of cash... but its just not big enough
[19:59:15] <zeeshan> 10hp not big enuf? :p
[19:59:33] <zeeshan> lol tom
[19:59:36] <PetefromTn_> not to run a 7.5hp motor single phase
[19:59:46] <zeeshan> oh ya
[19:59:49] <zeeshan> only 6.5hp output
[19:59:50] <zeeshan> or something
[19:59:56] <zeeshan> so close!
[20:00:02] <PetefromTn_> yeah it sucks
[20:00:13] <zeeshan> do you really need that extra 1hp?
[20:00:16] <PetefromTn_> I wish they had a similarly inexpensive one that is 15hp
[20:00:29] <PetefromTn_> well I paid for it I might as well get it LOL
[20:00:32] <zeeshan> hahah
[20:00:35] <Tom_itx> zeeshan some old datafile code i use
[20:00:46] <PetefromTn_> honestly the lathe ALSO came with a 5hp motor from the factory
[20:00:54] <PetefromTn_> the 7.5 was an option
[20:01:01] <Sync> you can probably overload it for long enough
[20:01:26] <PetefromTn_> ?
[20:01:31] <zeeshan> i agree with sync
[20:01:38] <zeeshan> usually vfds are designed to handle 120% overload
[20:01:45] <zeeshan> so 10hp can actually handle 12hp for short periods of time
[20:01:59] <PetefromTn_> hm
[20:02:03] <zeeshan> you're not going to really be sitting at 7.5hp constantly
[20:02:09] <PetefromTn_> well if it was a mill maybe but a lathe?
[20:02:23] <PetefromTn_> yeah doubt it
[20:02:32] <Sync> even on a lathe you only cut for so long
[20:02:33] <PetefromTn_> probably half that most of the time or less
[20:02:38] <SpeedEvil> What would a CNC thing that can handle non-rotating tools be? Say that can push a standard lathe type insert through steel taking 1mm cuts.
[20:02:46] <SpeedEvil> (other than expensive)
[20:02:55] <zeeshan> i think 7.5hp would mean like 3/8" cut at 0.015ipr
[20:02:57] <zeeshan> in mild steel
[20:03:19] <zeeshan> whats the difference between cost
[20:03:24] <PetefromTn_> well keep in mind this is not a gear head lathe
[20:03:26] <zeeshan> of the 2 drives
[20:03:34] <zeeshan> its direct drive?
[20:03:38] <PetefromTn_> unfortunately almost half
[20:03:49] <PetefromTn_> yeah direct multi vee belt drive
[20:04:21] <PetefromTn_> the hitachi is like 778 shipped
[20:04:30] <PetefromTn_> and yours was like 398 or something?
[20:04:39] <Sync> 778 is not that bad
[20:04:42] <PetefromTn_> that would buy a bunch of cheesecake
[20:04:52] <PetefromTn_> Sync no actually it is not really
[20:05:03] <PetefromTn_> but 398 is MUCH better ;)
[20:05:18] <Sync> sure
[20:07:43] <PetefromTn_> http://www.ebay.com/itm/15-hp-ac-drive-inverter-variable-frequency-phase-converter-speed-control-230v-/271987174231?hash=item3f53b2eb57:g:PNkAAOSw9r1V-B3g
[20:07:46] <PetefromTn_> new one there.
[20:07:57] <zeeshan> my numbers were completely off
[20:07:57] <zeeshan> btw
[20:08:26] <ssi> PCW: i found a bug in the 7i77 manual, sserial section
[20:08:31] <zeeshan> .375 doc in mild steel (1018 cd) , at 0.015ipr, 500sfm
[20:08:40] <zeeshan> requires 24hp!!
[20:08:59] <ssi> PCW: under SPECIAL RPCS, DiscoveryRPC and UnitNumberRPC are correctly numbered as 0xBB and 0xBC respectively
[20:09:22] <PetefromTn_> heh maybe on your monster lathe
[20:09:29] <zeeshan> pete here
[20:09:42] <zeeshan> like with carbide you wanna run it at .008 ipr usually
[20:09:42] <ssi> under SSERIAL REMOTE RPCS, the next section, they're swapped, Discovery is listed as 0xBC and UnitNumber is listed as 0xBB
[20:10:23] <PetefromTn_> no man I just meant I will not be ABLE to make that cut on this lathe with only 7.5hp
[20:10:24] <zeeshan> lets go w/ .010ipr, .125doc , 1018 cd
[20:10:30] <zeeshan> requires 6hp
[20:10:32] <ssi> .015 is a hell of a chipload
[20:10:33] <zeeshan> so that'd be the limit..
[20:10:40] <PCW> Ahh of course thats in about every sserial daughtercard manual :-(
[20:10:46] <ssi> PCW: yeah I figured as much :)
[20:10:48] <zeeshan> ssi pretty common w/ carbide tho!
[20:11:11] <Tom_itx> cutting a 3tpi thread might take a few hp in steel, other than that i doubt you'd press it to the full 7.5 hp
[20:11:16] <PetefromTn_> http://www.ebay.com/itm/WEG-CFW08-7-5HP-230V-NEMA4X-Variable-Frequency-Drive-/272036851141?hash=item3f56a8edc5:g:j8gAAOSwBahVHXVl is this 3 phase I am sure?
[20:11:22] <ssi> PCW: I thought I found my bug! was painstakingly transcribing from the scope (since my stupid cheap usb logic analyzer died), and I saw it respond to 0xBC with unit number, and the manual said it should be 0xBB
[20:11:28] <ssi> seemed like a smoking gun! but alas, no that's not the issue
[20:11:35] <PCW> Though you are the first one that have noticed it
[20:11:39] <Tom_itx> because on threads you're taking a full cut on the near final passs that will take some HP
[20:11:42] <ssi> sweet, do I get a prize? :D
[20:12:30] <zeeshan> you could do a .3 doc @ 0.010ipr , 500sfm
[20:12:33] <zeeshan> in 6061 though!
[20:12:34] <zeeshan> :D
[20:12:36] <Tom_itx> PetefromTn_, this took some HP from the spindle motor on the final couple passes: http://tom-itx.no-ip.biz:81/~webpage/temp/thread1.jpg
[20:12:58] <Tom_itx> you're not normally gonna take that big a cut at once at that feedrate
[20:13:07] <zeeshan> thats true :P
[20:13:12] <zeeshan> unless youre baws!
[20:13:44] <Tom_itx> well when i was making test specimens i pushed it pretty hard to get to final diameter
[20:13:58] <PetefromTn_> yeah I figure a CNC lathe can often be faster taking multiple cuts at higher feedrates than hogging in a single
[20:14:07] <zeeshan> buttttttttt
[20:14:10] <Tom_itx> put an ammeter on it
[20:14:12] <zeeshan> tool life rapidly decreases
[20:14:14] <zeeshan> if you do that
[20:14:14] <Tom_itx> to monitor it
[20:14:24] <duc> A production shop may take that if it's the one item they make. Time is money and more parts
[20:14:25] <Tom_itx> mark on the meter where 'marginal' is
[20:14:54] <Tom_itx> duc, a production shop is also aware not to grind their equipment into the dirt
[20:15:02] <PetefromTn_> I am used to a 12x36 chinko lathe with 2 chinko HP....I think this machine will be MORE than enough for me ;)
[20:15:03] <zeeshan> i had the infamous question on my final exam, keeping time constant, is it better to take 2 passes at double the feed rate
[20:15:07] <Tom_itx> and have massive downtime
[20:15:08] <zeeshan> or one single pass at half the feedrate
[20:15:10] <zeeshan> :D
[20:15:17] <ssi> and what's the answer
[20:15:22] <zeeshan> single pass
[20:15:25] <ssi> why
[20:15:32] <zeeshan> tool life isn't related to depth of cut
[20:15:43] <zeeshan> but a strong function of feed rate
[20:15:44] <SpeedEvil> You're not cutting while transiting?
[20:15:51] <ssi> ah
[20:15:58] <duc> We push our equipment to max removal. Only so much equipment can fit or produce so much stuff if your going easy
[20:16:18] <zeeshan> order of importance
[20:16:21] <zeeshan> sfm , feedrate
[20:16:25] <duc> Main reason to not buy a haas or bridgeport in a manufacturing shop
[20:16:27] <zeeshan> that class was really useful
[20:16:37] <zeeshan> whats wrong with haas
[20:16:40] <zeeshan> haas makes good machines
[20:16:40] <PetefromTn_> If I ever get into some serious production I will worry about it then or get another machine... for right now this should be MORE than enough
[20:16:46] <zeeshan> i think youre confusing haas w/ tormach
[20:16:52] <Tom_itx> zeeshan i doubt they're as heavy as a mori or okuma
[20:16:59] <Tom_itx> or tree for that matter
[20:17:06] <zeeshan> for the same price, no
[20:17:15] <duc> Haas is good for 5 years versus a mori, okoma and a few others
[20:17:19] <zeeshan> most people are used to seeing the pansy haas machines
[20:17:20] <PetefromTn_> more like half the price
[20:17:24] <duc> But yes most are fine with haas
[20:17:41] <zeeshan> what do you mean good for 5 years
[20:17:44] <Tom_itx> i'm sure they've improved over recent years
[20:17:54] <Tom_itx> zeeshan, tolerances start to fail
[20:18:02] <duc> We kill a haas in 5 years. Pull and replace
[20:18:08] <zeeshan> ah
[20:18:11] <duc> 15 years for better units
[20:18:15] <Tom_itx> if you grind them into the dirt like the duc production shop is
[20:18:46] <zeeshan> i dunno man, i've seen plenty of success stories for manufacturing plants
[20:18:48] <zeeshan> running haas 24hrs
[20:18:51] <zeeshan> im not a haas fan boi
[20:18:58] <zeeshan> trust me, i never used to like haas, till i looked into it myself
[20:19:01] <PetefromTn_> thats funny because there are a half dozen shops within a ten mile radius of my home that have nothing but HAAS machines running 24/7 making tool steel parts...
[20:19:06] <Tom_itx> i've seen a few as well
[20:19:08] <zeeshan> exactly pete
[20:19:16] <zeeshan> haas haters i think are based on their older machines
[20:19:23] <zeeshan> and its likely germans spreading the hate
[20:19:23] <zeeshan> :P
[20:19:25] <Tom_itx> i don't hate em
[20:19:33] <Tom_itx> i don't think they're as rugged as some
[20:19:43] <zeeshan> theyure definitely not
[20:19:52] <zeeshan> i haven't really ever seen a haas with a hsk taper
[20:19:54] <duc> Lol. Haas as its place but not as rugged and can't hold tolerance like okoma
[20:19:59] <PetefromTn_> the one shop I worked in had their ORIGINAL HAAS a VF3 that is almost 20 years old now... it is still making parts
[20:19:59] <zeeshan> you know you're serious business when you got hsk
[20:20:04] <PCW> ssi:
[20:20:05] <PCW> http://freeby.mesanet.com/LBP.PAS
[20:20:07] <PCW> http://freeby.mesanet.com/SSLBPLOW.PAS
[20:20:20] <zeeshan> duc: i blame operator :-)
[20:20:31] <Tom_itx> i don't agree
[20:20:35] <Tom_itx> entirely
[20:20:40] <duc> I will say a bridgeport gx309 can take a fucking hit but suck overall for problems
[20:20:46] <duc> Gx300
[20:20:52] <duc> We have 50 of them
[20:20:52] <PetefromTn_> I am not arguing that a HAAS is as good as the others understand
[20:21:05] <Sync> zeeshan: depends
[20:21:06] <ssi> PCW: oh boy this looks terrifying :D
[20:21:16] <Sync> a lot of guys I know are changing back to regular tapers
[20:21:18] <PetefromTn_> but the argument that they only last 5 years is hard to swallow
[20:21:27] <jdh> wow, haven't seen any of that in years
[20:21:42] <zeeshan> wtf am i reading this code
[20:21:43] <PetefromTn_> at the end of the day they are less than half the price of most of the japan machines
[20:21:44] <zeeshan> is this assembly
[20:21:58] <Tom_itx> PetefromTn_ i've seen some pretty shabby operators around here... i could believe it
[20:22:03] <PCW> well the remote only needs to implement what SSLBP uses
[20:22:03] <PetefromTn_> and even if they only lasted half as long its a wash
[20:22:06] <Tom_itx> err monkeys..
[20:22:07] <duc> Yea massive row for producing one type of part. 3shifts a day
[20:22:10] <zeeshan> pcw where are the comments? :-)
[20:22:16] <ssi> there are comments
[20:22:52] <Tom_itx> i ran a row of 6 & 8 spindle lathes for several years, the week after i quit, they set an 8 spindle on fire
[20:22:52] <duc> We do have a few haas with a million+ tool changes for AL maching
[20:23:05] <zeeshan> duc: in a tier 1 supplier manufacturing plant
[20:23:07] <zeeshan> theres no such thing as haas
[20:23:19] <zeeshan> which is why i never really took haas seriously
[20:23:23] <Sync> you'd be amazed
[20:23:23] <ssi> zeeshan: what about paas?
[20:23:37] <ssi> without paas, how we goan dye our easter eggs?!
[20:23:39] <duc> We aren't auto but firearms
[20:23:49] <Sync> I know someone that does gearbox machining for a skidoo manuf
[20:23:51] <ssi> duc: oo which one
[20:23:58] <Sync> all haas + one okuma
[20:24:05] <zeeshan> Sync: they arent a tier 1 supplier
[20:24:06] <zeeshan> :p
[20:24:20] <Sync> for their market, they are
[20:24:36] <duc> Mystery. Lol
[20:24:39] <zeeshan> im not saying tier 1 as in like they're the go to for supply
[20:24:39] <ssi> figures :)
[20:24:54] <zeeshan> im saying tier1 as in if you ddon't produce 700parts with no more than 1 failed part
[20:24:58] <zeeshan> you lose your entire plant
[20:25:25] <zeeshan> those guys don't f around with haas
[20:25:38] <duc> Zeeshan is right
[20:25:49] <zeeshan> (im not saying haas is bad, but im just saying the big boys don't run them for a reason)
[20:25:51] <ssi> zeeshan is often right
[20:25:53] <ssi> but never in doubt
[20:25:55] <duc> Time is money and some industry have a small margin
[20:26:01] <PCW> ssi: the state params can be helpful when debugging (SSLBPs state will reflect when it got stuck)
[20:26:18] <ssi> PCW: I still don't have a clear idea of how to get at those
[20:26:29] <Sync> oh I actually have seen some haas and doosan in VW suppliers plants
[20:26:33] <zeeshan> i dont know why im reading the sslbp code
[20:26:34] <Sync> but not in the balls to the wall ones
[20:26:39] <zeeshan> it's so cleanly written
[20:26:40] <zeeshan> maybe thats why
[20:27:04] <PCW> they are accessible from the host (linuxcnc) side
[20:27:09] <ssi> PCW: yeah, but how? :D
[20:27:22] <zeeshan> Sync: prolly the tool room machine
[20:27:22] <zeeshan> :-)
[20:27:28] <Sync> nah
[20:27:37] <PCW> raw-read
[20:27:37] <duc> I would love a haas in my garage. But 416 ss heat treat to 38 rc is mean on machines if it's 24/7
[20:28:01] <Sync> but the one shop has gone to all dmc 105 linears
[20:28:06] <ssi> PCW: is that related to "Raw Mode" that I see in the hm2 man page?
[20:28:13] <zeeshan> Sync: how dare you support haas
[20:28:15] <zeeshan> you're german
[20:28:19] <zeeshan> it's against your blood nature
[20:28:27] <Sync> well, how can I support the dmg idiots? :D
[20:28:35] <zeeshan> haha dmg is top notch cude
[20:28:36] <PCW> I think theres a HAL pin but I dont think its valid if the remote doesn't start
[20:28:37] <zeeshan> *dude
[20:28:58] <PetefromTn_> vfdvfdvfdvfdvfdvfd.....grrr grrrrrr
[20:29:00] <ssi> If the "enable_raw" config keyword is specified, some extra debugging pins are made available in HAL. The raw mode HAL pin names begin with "hm2_<BoardType>.<BoardNum>.raw".
[20:29:03] <duc> Lol
[20:29:07] <zeeshan> PetefromTn_: if my opinion matters
[20:29:08] <Sync> the only ones I can support are hermle
[20:29:13] <PCW> raw mode just lets you read bare registers
[20:29:14] <zeeshan> i'd save up for the bigger drive
[20:29:16] <zeeshan> and not f around
[20:29:16] <PetefromTn_> oh it doesn't ;)
[20:29:22] <Sync> zeeshan: their support sucks
[20:29:30] <zeeshan> Sync: i attest to that
[20:29:31] <PetefromTn_> just kidding man
[20:29:34] <ssi> not taht then
[20:29:36] <zeeshan> their support sucks if you're a small time shop
[20:29:52] <zeeshan> but they'll sniff your you know what, if youre a tier1
[20:30:24] <ssi> oh I've actually got sserial errors in console
[20:30:28] <ssi> I didn't even notice that before
[20:30:35] <PetefromTn_> you would think if Hitachi can make and sell a drive for 775 there would be chinese ones tripping over themselves for half that much...
[20:30:37] <ssi> hm2/hm2_5i25.0: hm2_sserial_waitfor: Timeout (25mS) waiting for addr 5a00 &mask ffffffff val 1004
[20:30:43] <zeeshan> duc 416 doesn't seem hard to machine in paper..
[20:30:50] <zeeshan> 85% machinability index
[20:30:57] <zeeshan> thats in par with cd steel
[20:31:10] <Sync> that might be true, but it still keeps me from getting a machine from them
[20:31:22] <PetefromTn_> from who?
[20:31:30] <Sync> dmg
[20:31:39] <PetefromTn_> DMG are nice machines
[20:31:40] <zeeshan> i think their machines look alittle dorky
[20:31:42] <duc> Not to bad but we can make d.o.c and speed.
[20:31:45] <zeeshan> with their fancy enclosures lol
[20:31:51] <ssi> I imagine that's where it's trying to dive into the ptoc
[20:31:57] <ssi> looks like there's an address backwards
[20:32:02] <duc> Take max D.O.C. Dam phone
[20:32:07] <ssi> 0x005a sounds saner than 0x5a00 for my code
[20:32:23] <ssi> the remote is running, there's a 1khz stream of processrpc
[20:32:28] <PetefromTn_> really impressed with these DMM servos and drives so far
[20:32:30] <ssi> but I have no pds reported in dmesg
[20:32:35] <PetefromTn_> even the manual is nice
[20:32:40] <zeeshan> PetefromTn_: you have them in your cinci right?
[20:32:46] <ssi> cinci is tecos
[20:32:51] <PetefromTn_> no I used the TECO's in the cinci
[20:33:00] <ssi> not as tasty as tacos, and way more money
[20:33:06] <PetefromTn_> which are also nice but their manual is typical chinese
[20:33:22] <duc> I was going to get some DMM but couldn't find to much info about them
[20:33:42] <PetefromTn_> I just got them and have not installed or run them yet but they certainly look legit
[20:33:51] <PetefromTn_> and DMM got them here in a HURRY
[20:33:51] <duc> Plus missed the 500 dollar sets on ebay for 750 watt motor setup
[20:33:57] <zeeshan> h,mm pete
[20:33:59] <PetefromTn_> they also made me a great deal on them
[20:34:00] <zeeshan> now you got me thinking..
[20:34:07] <zeeshan> their 1.8kW model is not too expensive
[20:34:12] <duc> What are you installing them on?
[20:34:13] <PetefromTn_> duc if you want them call them direct
[20:34:34] <PetefromTn_> a Standard Modern CNC lathe 14x45
[20:34:37] <duc> Already got yaskawa setup off ebay for same price
[20:34:49] <PetefromTn_> really?
[20:34:55] <duc> Yea
[20:34:58] <PetefromTn_> yaskawa are really good drives
[20:34:59] <zeeshan> brand new?
[20:35:42] <zeeshan> PetefromTn_: im liking this:
[20:35:42] <duc> Motors are suppose to be low hours
[20:35:43] <PetefromTn_> this was a motor, driver, cables encoder/power and tuning with software shipped for under $500 an axis
[20:35:50] <zeeshan> The DYN4 servo drive accepts both single and three phase inputs for all drive models. This simplifies application and installation requirements. Input voltage is also universal 110~230VAC 50/60Hz. Compatible into any system with specific power, space or cost requirements.
[20:36:27] <PetefromTn_> zeeshan yeah?
[20:36:40] <duc> I did find the motor shaft odd on the DMM. Dmm is 14mm for 750w while yaskawa is 19mm
[20:37:23] <PetefromTn_> duc if you got a yaskawa motor driver and cables set even used for under $500 you did awesome
[20:37:44] <duc> Motor was 150, driver 169 and cable for 70
[20:37:54] <Sync> we just got one for 180€
[20:37:55] <zeeshan> new?!?!
[20:37:55] <PetefromTn_> fuck thats cheap
[20:37:57] <zeeshan> thats cheap
[20:38:02] <Sync> complete with axis, drive, motor and cable
[20:38:17] <duc> Had to buy separate but low balled people
[20:38:27] <PetefromTn_> how much is 180 whatever the hell that thingis?
[20:38:33] <zeeshan> lol
[20:38:50] <PetefromTn_> oh
[20:39:08] <PetefromTn_> I am sure you could piece together used component purchases on ebay and beat my deal
[20:39:19] <Sync> yuros
[20:39:23] * zeeshan still hasnt heard if it was new or not
[20:39:24] <zeeshan> if its used
[20:39:28] <PetefromTn_> :S
[20:39:29] <Sync> so 195usd
[20:39:29] <zeeshan> thats not a fair comparison :p
[20:39:59] <duc> Slightly used supposedly. I was really close to buying dmm just not enough info
[20:40:00] <PetefromTn_> I'm not saying I got the greatest deal in the world here LOL just that I am pretty happy with it all
[20:40:10] <PetefromTn_> not enough info?
[20:40:11] <zeeshan> LONG LIVE CANADA
[20:40:20] <PetefromTn_> :D
[20:40:25] <zeeshan> canada thanks you for your american currency
[20:40:32] <PetefromTn_> enjoy it mate!
[20:40:39] <PetefromTn_> thanks for the great deal!
[20:40:40] <duc> I even made pulley adapters for my bridgeport. What the hell will I use a 5mm keyway broach for and a 14mm reamer
[20:40:57] <zeeshan> i think the problem is you have a bridgeport
[20:41:02] <duc> Not much on forums about quality
[20:41:03] * zeeshan hides
[20:41:29] <PetefromTn_> actually DMM has been selling for a couple years now and there are lots of folks using them online
[20:41:32] <duc> Lol. Bridgeport boss 5 and leblond 15x30 was earned in a trade for a ar15
[20:41:44] <PetefromTn_> but at the end of the day its all chinese stuff anyway
[20:41:56] <PetefromTn_> for the price if something goes wrong it is cheap enough to replace
[20:42:02] <duc> BRB switching to computer
[20:42:39] <Duc> Much better dam phone is hard
[20:43:16] <Duc> Link to the motors
[20:43:17] <Duc> http://www.ebay.com/itm/171152820529?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
[20:43:37] <zeeshan> cute motor
[20:43:54] <Duc> And controller http://www.ebay.com/itm/161797026282?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
[20:43:55] <zeeshan> might rip that bridgeport apart
[20:43:56] <zeeshan> :D
[20:44:18] <Duc> Probably will but then I can convice the wife I need a VMC
[20:44:24] <ssi> do those motors have encoders?
[20:44:27] <zeeshan> im kidding
[20:44:31] * zeeshan is in troll mode
[20:44:41] <ssi> looks like it, but there's no data
[20:44:46] <ssi> also can you get those funky connectors on it?
[20:44:46] <PetefromTn_> those look almost identical to my motors hehe
[20:44:52] <Duc> absolute encoders on them
[20:44:59] <ssi> oh the proprietary ones
[20:45:13] <Duc> yep but drives output a quad signal
[20:45:18] <ssi> right
[20:45:20] <ssi> locks you into their drives
[20:45:24] <ssi> and you'll need a cableset too
[20:45:28] <ssi> which isn't gonna be cheap I bet!
[20:45:37] <Duc> going to buy cables tonight once I get off my ass $70 a set
[20:45:51] <ssi> http://www.ebay.com/itm/YASKAWA-SGDV-5R5A01A-SERVO-DRIVER-750W-SGMJV-08ADA21-MOTOR-TESTED-WORKING/181803694582?_trksid=p2047675.c100009.m1982&_trkparms=aid%3D777000%26algo%3DABA.MBE%26ao%3D1%26asc%3D20131227121020%26meid%3De112de074fc748b7bc339f0d55cb4ec1%26pid%3D100009%26rk%3D1%26rkt%3D1%26sd%3D161797026282
[20:47:03] <zeeshan> pcw i read a paper on torque control vs speed control
[20:47:13] <zeeshan> and i don't see why you're saying its better for Z axis
[20:47:14] <Sync> ssi: they use 4mbit hdlc
[20:47:36] <Duc> figure I spent $389 a axis including motor, drive and cable
[20:47:51] <ssi> Duc: not bad
[20:48:22] <Duc> Im cheap since I dont make anything off the mill for money. Plasma table has made some
[20:48:40] <PetefromTn_> thats a low price and definitely worth it. I am happy with the DMM's tho. a bit more money but all brand new ready to go
[20:49:03] <PCW> zeeshan: It depends on the drive: with a simple velocty mode drive you cannot do torque offset to balance gravity
[20:49:07] <Duc> I will have to follow your build to see if thats for the next project
[20:49:27] <PetefromTn_> I ALMOST went with DMM for the Cincinatti
[20:49:33] <ssi> torque offset to balance gravity
[20:49:35] <ssi> that sounds cool
[20:49:39] <ssi> Sync: think we can do that in stmbl?
[20:49:45] <zeeshan> PCW: but the problem is if you're in torque mode, and you crash into something
[20:49:45] <Duc> What stopped you
[20:49:51] <zeeshan> it'll try to accelerate even harder
[20:49:54] <PCW> (for un-counterbalnced Z Axis on a mill)
[20:50:00] <PetefromTn_> but at the time their price was higher than Teco by a few bucks an axis and they were in Canada so I was concerned right off the bat...
[20:50:15] <zeeshan> and how do you predict the moment of inertia of the system?
[20:50:24] <ssi> PetefromTn_: yeah I'd be concerned too man... I mean, it's canada
[20:50:27] <PetefromTn_> I mean lets face it nothing good comes from Canada ;)
[20:50:35] <PCW> nope torque is where that belongs (so the velocity loop sees a symmetrical system)
[20:50:37] <Duc> LOL Im almost canada since I lived in ND
[20:50:48] <Duc> for 17 years
[20:50:56] <PetefromTn_> jeez don't you freeze your frackin' ass off in winter?
[20:51:09] <Duc> Im now in AL
[20:51:19] <PetefromTn_> ah
[20:51:53] <ssi> Duc: now I know who you work for :D
[20:51:58] <Duc> LOL
[20:52:02] <PetefromTn_> the guys at DMM were very helpful on the phone both times I talked to them and they responded via email as quickly as could be expected considering the time difference
[20:52:28] <Sync> ssi: yes, most probably
[20:52:32] <Duc> I got excellent service for emails from them. Even weekend replies
[20:52:39] <PetefromTn_> ya know what else?
[20:52:51] <PetefromTn_> I was expecting to have to pay customs fees
[20:52:54] <ssi> Sync: sic crinq on it
[20:53:06] <PetefromTn_> DMM said the fees were typically somewhere between 2 and 8 percent
[20:53:10] <ssi> I blowed up my code again
[20:53:13] <ssi> and reverting it didn't fix it
[20:53:15] <ssi> that drives me nuts
[20:53:26] <PetefromTn_> but the driver from DHL delivered right to my door
[20:53:31] <PetefromTn_> I signed and he left
[20:53:40] <PetefromTn_> will I be billed for it later or something?
[20:53:41] <zeeshan> bill comes a couple days alater
[20:53:43] <zeeshan> yes
[20:53:45] <zeeshan> dhl is lame like that
[20:53:53] <Sync> ssi: that is why rene bought the yaskawa drive
[20:53:54] <PetefromTn_> shit
[20:54:01] <Duc> Interesting. I know CNC4PC had the 750 kit for $700 but I should have called to check on the $500 kit
[20:54:05] <zeeshan> honestly i think that's a massive scam
[20:54:12] <zeeshan> cause you could reject the package
[20:54:16] <zeeshan> but they take that choice away from you
[20:54:24] <ssi> Sync: ah cool
[20:54:26] <zeeshan> by not infomring you the customs charges at the time of delivery
[20:54:39] <Sync> you can always just request to deal with customs yourself
[20:54:41] <PetefromTn_> Duc honestly I TRIED to get them from CNC4PC
[20:54:42] <ssi> Sync: gonna RE the yaskawa absolute encoder format?
[20:54:47] <zeeshan> sync hav eyou tried that?
[20:54:50] <zeeshan> that's another major scam !
[20:54:51] <PetefromTn_> he refused to work with me
[20:54:54] <zeeshan> i tried!
[20:54:58] <Sync> we basically reverse engineered it already ssi
[20:55:00] <Sync> yes zeeshan
[20:55:03] <Sync> I do it all the time
[20:55:05] <ssi> cool
[20:55:06] <zeeshan> its hard up here
[20:55:47] <Sync> here I tell them, nothanks plz gtfo with your bill, I'll handle it
[20:55:49] <PetefromTn_> we went back and forth for several days after he initially said he would be able to make a similar deal to that ebay sale
[20:56:09] <zeeshan> are these chinese drives?
[20:56:22] <Duc> Still wondering why the difference in motor shaft sizes.
[20:56:37] <PetefromTn_> but at the end of the day he did not come down much off his original posted price
[20:56:51] <PetefromTn_> zeeshan I believe they are chinese but I honestly don't know
[20:57:00] <zeeshan> does it have a made in sticker
[20:57:11] <PetefromTn_> duc I dunno man but 14mm is plenty for a motor of this size
[20:57:28] <zeeshan> what rpm is your servo
[20:57:31] <zeeshan> peak
[20:57:41] <ssi> Sync: how come your compatriots dont stay up all night like you do?
[20:57:44] <Duc> no doubt.
[20:57:51] <PetefromTn_> dunno I was trying to take a picture for you guys but my damn cellphone croaked and I had to charge it ;)
[20:57:54] <ssi> my work schedule is interfering with my german hackfest schedule
[20:57:55] <ssi> :(
[20:58:07] <Duc> 3000 RPM but let me check max
[20:59:32] <PetefromTn_> mine are 3k RPM 2,4nm
[21:00:26] <Sync> ssi: crinq is awake, we're discussing the nextgen™®© hardware
[21:00:30] <Duc> max 6,000 RPM
[21:00:55] <Duc> @2.4 NM
[21:01:00] <PetefromTn_> Holy smokes both the drives and the motors say made in canada
[21:01:03] <ssi> Sync: I hope you're gonna keep the eagle files in git as you work on it, I want to weigh in :)
[21:01:27] <Sync> we're slowly migrating to kicad
[21:01:40] <mozmck> what are you making?
[21:01:45] <Duc> acutally 3k rpm @2.4 then drops off to 1 NM at 6k RPM
[21:02:28] <Sync> you can already look at the bob if you want ssi
[21:02:37] <ssi> Sync: yea I want
[21:02:41] <ssi> mozmck: SECRETS
[21:02:55] <mozmck> :)
[21:04:50] <zeeshan> 14mm = .551"; Torque using 3000rpm, 1hp: T = 5252*1/3000=1.751 ft-lb, shear stress = Tr / J . assume mild steel shaft, shear yield strength is .577*30000psi = 17310psi. , shear stress = ((1.751*12)*(.551/2))/(pi*.551^4/32) = 640 psi
[21:04:57] <zeeshan> hopefully i didnt make a calc error
[21:05:03] <zeeshan> but i think you're safe with a 14mm shaft :p
[21:05:25] <Duc> I was to dam lazy to break out the ME math
[21:05:44] <zeeshan> never assume
[21:05:46] <zeeshan> calculate
[21:05:47] <PetefromTn_> hehe
[21:06:35] <PetefromTn_> I aalways figured motor shafts were stainless
[21:06:41] <Duc> I would question that result cause otherwise the chinese would make it with a smaller shaft
[21:07:12] <PetefromTn_> apparently its not chinese :D
[21:08:26] <Duc> Hm what how long of a cable I need for the x-axis
[21:08:46] <PetefromTn_> I got 5 meter cable sets for my lathe
[21:09:17] <zeeshan> http://i.imgur.com/KMeT6oW.png
[21:09:19] <Sync> nah PetefromTn_
[21:09:22] <zeeshan> fak you fea
[21:09:24] <zeeshan> always slightly off
[21:09:27] <Sync> I got plenty of rusted servo shafts
[21:09:35] <zeeshan> 1133psi it says
[21:09:48] <PetefromTn_> Sync LOL
[21:09:53] <zeeshan> fatigue is prolly around 6x that number
[21:10:03] <zeeshan> so its still 3 times bigger than it needs t obe
[21:10:04] <zeeshan> :P
[21:10:11] <PetefromTn_> hehe for this small a motor I am sure its fine
[21:10:36] <zeeshan> i was reading an article a while back because i was curious why motor frames dictate shaft size
[21:10:40] <zeeshan> cause i didnt see the relatiosnhip
[21:10:46] <zeeshan> apparently it was a silly thing done back on the day
[21:10:46] <PetefromTn_> I had nema 34 1125 oz in motors on my RF45 DC servos and the shafts were even smaller than these
[21:10:54] <zeeshan> it has nothing to do with the shaft failing
[21:11:05] <Sync> yeah
[21:11:08] <Sync> it is just because
[21:11:12] <zeeshan> yea "just because"
[21:11:13] <zeeshan> lol
[21:11:22] <zeeshan> "looks about right"
[21:11:37] <PetefromTn_> I figured it had more to do with the size of the motors internals than anything else
[21:11:41] <Duc> or if they used a standard material size since custom sizes cost more
[21:11:57] <Sync> they are usually always ground
[21:12:04] <Sync> so standard sizes don't matter
[21:12:15] <Duc> Ground stock still comes in standard sizes
[21:12:35] <PetefromTn_> its probably ground at the manufacturer
[21:12:52] <PetefromTn_> of the motor
[21:12:52] <Sync> yeah but rotors don't come in standard sizes
[21:13:04] <Duc> Not if they can get away from it. Cost money and a person to operate a centerless grinder
[21:13:12] <PetefromTn_> this is so awesome I am FINALLY gonna have a CNC lathe here
[21:13:25] <zeeshan> im happy for you :D
[21:13:42] <PetefromTn_> I can't wait to make a CHESS SET!! ;)
[21:13:59] <zeeshan> ssi, so i heard you're buying a tormach?
[21:14:07] <ssi> did you?
[21:14:09] <ssi> nobody told me
[21:14:11] <zeeshan> :D
[21:14:13] <PetefromTn_> lol
[21:14:13] <Duc> Lucky, No more tools till I get a work shop only so much fits in a 2 car garage
[21:14:22] <PetefromTn_> heh
[21:14:27] <ssi> I can't own tormach, it's got mach right in the name
[21:14:31] <PetefromTn_> I have a VMC and a CNC lathe in a 2 car garage
[21:14:32] <zeeshan> you should buy one
[21:14:37] <zeeshan> and mill it into pieces w/ your machine
[21:14:40] <ssi> lol
[21:14:49] <ssi> sounds like a lot of money that I could use to build another laser :)
[21:14:54] <zeeshan> your table prolly has a 1500lb capacity?
[21:14:54] <zeeshan> :D
[21:14:58] <ssi> I dunno what it is
[21:14:59] <Duc> Surface grinder, 5x5 ft plasma table, 15x30 lathe, bridgeport cnc mill and a massive toolbox
[21:15:01] <ssi> I'm sure it's a lot
[21:15:01] <PetefromTn_> I think its funny how zeeshan hates tormach LOL
[21:15:08] <zeeshan> dude i'll make sure you get 100,000,000 views
[21:15:25] <zeeshan> PetefromTn_: i think it's cause of john nycnc
[21:15:34] <PetefromTn_> Oh I got more than that in here man LOL
[21:15:35] <zeeshan> i had the hardest laugh the other day
[21:15:41] <zeeshan> and i swear, i am not trying to be a dick or anything
[21:15:48] <zeeshan> when he announced he's offering cnc classes
[21:15:48] <zeeshan> ROFL
[21:15:49] <PetefromTn_> Oh perish the thought
[21:15:58] <zeeshan> he's starting a school or something
[21:16:05] <PetefromTn_> WOW
[21:16:07] <Duc> in time in time
[21:16:24] <zeeshan> that noob is going to be teaching others....... scary thought
[21:16:39] <PetefromTn_> duc this is not a hobby for me man I am trying to make money in here as crazy as that may sound
[21:17:10] <PetefromTn_> zeeshan I did something I have never done before at the shop today
[21:17:11] <zeeshan> PetefromTn_: trying?!
[21:17:12] <zeeshan> you already are :d
[21:17:17] <Duc> at least your making money. Mine is for fun on the weekend for an hour
[21:17:32] <PetefromTn_> yeah so far it is looking pretty good
[21:17:57] <Duc> I did build a 20mm rifle with the crap at least
[21:18:10] <zeeshan> what did you do
[21:18:27] <PetefromTn_> we are building that RX7 that has the LS-A motor in it
[21:18:33] <Duc> a 20 mike mike rifle. Makes a 50 BMG look like childs play
[21:18:40] <ssi> nice
[21:18:46] <zeeshan> wait
[21:18:50] <zeeshan> he's keeping the supercharger on it??
[21:18:53] <zeeshan> fd??
[21:18:57] <PetefromTn_> yeah it is blown
[21:18:59] <zeeshan> !!!!!!
[21:19:01] <zeeshan> dude snap some pics
[21:19:06] <zeeshan> thats a unique build
[21:19:09] <PetefromTn_> supposed to make like 575hp
[21:19:15] <PetefromTn_> I will
[21:19:17] <zeeshan> yea it makes that stock
[21:19:18] <Duc> Look up 20mm rifle build Pirate4x4
[21:19:23] <zeeshan> but you can easily push 650 out of them
[21:19:30] <zeeshan> with not much changes
[21:19:31] <PetefromTn_> thats what they were saying
[21:19:38] <PetefromTn_> anyways
[21:19:49] <Duc> That will be a fun car
[21:19:51] <PetefromTn_> they pulled the motor and tremec tranny out of it
[21:20:03] <PetefromTn_> and put on the new fender flares
[21:20:17] <PetefromTn_> and the new front clip and side skirts that Sync despises ;)
[21:20:25] <zeeshan> noooooooooo
[21:20:25] <PetefromTn_> and they were like
[21:20:28] <PetefromTn_> say pete
[21:20:41] <ssi> Duc: is it rifled?
[21:20:51] <PetefromTn_> do you think you can tig weld up all the excess holes in the front frame section and the bodywork in the engine bay>
[21:21:02] <PetefromTn_> I was like uuuhhh I guess so
[21:21:12] <Duc> yes its a vulcan 20mm barrel that is over 55inch long
[21:21:14] <PetefromTn_> so they were like....get crackin'
[21:21:17] <zeeshan> haha
[21:21:20] <zeeshan> thats a lot of welding
[21:21:22] <ssi> oh you used an existing barrel?
[21:21:32] <PetefromTn_> honestly I did it in like two and a half hours
[21:21:40] <Duc> yea designed the bolt system and barrel extension out of S7 tool steel
[21:21:44] <PetefromTn_> die grinder with sanding disks
[21:21:49] <PetefromTn_> knock off the paint
[21:21:54] <Duc> dam bolt is about the size of a soda can
[21:21:56] <zeeshan> PetefromTn_: now we both have some japanese paint inside our body
[21:22:01] <PetefromTn_> clean the area and hit it with thick rod
[21:22:03] <zeeshan> the lovely smell of old jap paint
[21:22:10] <PetefromTn_> yeah it stinks LOL
[21:22:17] <R2E4_> hiya Pete
[21:22:24] <R2E4_> PCW and all
[21:22:27] <PetefromTn_> did you smooth the engine bay in your FD?
[21:22:31] <PetefromTn_> Hey R2
[21:22:32] <zeeshan> no
[21:22:34] <ssi> that would be a scary first test fire
[21:22:41] <zeeshan> but i did remove a lot of extra holes when doing body work
[21:22:51] <Duc> Hopefully soon been working to dam much
[21:22:52] <zeeshan> like my trunk has no holes for spoiler or rear wiper
[21:22:56] <PetefromTn_> it was kind of funny
[21:22:59] <zeeshan> and i got rid of the antenna hole
[21:23:14] <PetefromTn_> they asked me to do this and then they had to leave to meet a customer or something
[21:23:28] <PetefromTn_> they came back an hour or two later and I was cleaning up
[21:23:36] <PetefromTn_> they were like HOLY SHIT you finished?
[21:23:37] <Duc> http://i1221.photobucket.com/albums/dd465/shefron/20MM%20Rifle/20140825_215245_zpsp25hmcge.jpg
[21:23:39] <zeeshan> hahaha
[21:23:44] <zeeshan> nice!
[21:23:47] <zeeshan> you shoulda slowedddddddd down
[21:24:00] <PetefromTn_> they only marked the holes they wanted sealed up with a sharpie
[21:24:11] <PetefromTn_> most were on the front frame and in front of the wheel wells
[21:24:16] <PetefromTn_> so he is like
[21:24:24] <Duc> machined my own lower from scratch also
[21:24:36] <PetefromTn_> jeez man if I had known you could do it that fast I would have had you do BEHIND the wheel wells too
[21:24:54] <PetefromTn_> so tomorrow morning they are marking the ones behind there for me to seal up
[21:24:55] <zeeshan> dude you have to make plugs
[21:25:15] <PetefromTn_> for larger holes yeah
[21:25:31] <PetefromTn_> but most of these were easily fillable with just rod
[21:25:42] <zeeshan> nice
[21:25:51] <R2E4_> you arc welding?
[21:26:05] <PetefromTn_> the square ones that are on the sides I made little square pieces for
[21:26:09] <PetefromTn_> no tig
[21:26:23] <R2E4_> ah.... was going to say, they still arc weld today? lol
[21:26:33] <zeeshan> technically tig is arc welding
[21:26:34] <zeeshan> gtaw :)
[21:26:35] <zeeshan> smaw!
[21:26:37] <PetefromTn_> lots of people arc weld
[21:26:44] <Duc> https://www.youtube.com/watch?v=zmfn38Y-RHE
[21:26:46] <R2E4_> mig would be easier to fill jholes no?
[21:26:52] <zeeshan> yes it is
[21:26:54] <PetefromTn_> and yeah technically TIg is an arc weld
[21:27:08] <zeeshan> Duc: that is apretty frigging big ass bullet
[21:27:15] <Duc> mig works well with a piece of copper behind the hole
[21:27:28] <zeeshan> good luck getting copper behind some of those holes
[21:27:29] <zeeshan> :D
[21:27:34] <zeeshan> it'll be part of the car!
[21:28:03] <zeeshan> i wish canada gun laws werent as tight as they are
[21:28:04] <zeeshan> :/
[21:28:06] <Duc> I want to turn the mill into a mill turn to make a copper hollow point for a hog kill
[21:28:10] <PetefromTn_> after I get them all welded up I will snap a pic for ya
[21:28:10] <zeeshan> we cant own cool guns up here
[21:28:23] <Duc> also have a tax stamp to make a suppressor for the 20mm LOL
[21:28:30] <PetefromTn_> I have shot a few .50 BMG rifles
[21:28:35] <PetefromTn_> they are impressive
[21:28:41] <zeeshan> i havent shot shit
[21:28:42] <zeeshan> =/
[21:28:46] <PetefromTn_> but I fail to see the usefulness unless you are a marine
[21:28:52] <zeeshan> my friend has like 30 guns
[21:28:56] <zeeshan> hes always showing them off to me
[21:29:02] <Duc> imagine working in the firearm industry and seeing how many guns you buy
[21:29:03] <R2E4_> I shot in the military.
[21:29:17] <R2E4_> sharp shooter 9mm and shotgun.
[21:29:19] <zeeshan> r2e4: canadian military doesnt count
[21:29:20] <zeeshan> :-)
[21:29:30] <PetefromTn_> I have several guns and a couple target airguns
[21:29:37] <R2E4_> I am an American, I was in the US NAvy on Nuclear submarines
[21:29:38] <PetefromTn_> I really enjoy shooting
[21:29:41] <zeeshan> no c7?
[21:29:41] <zeeshan> oh
[21:29:56] <zeeshan> whyd you move to canada? :D
[21:30:05] <PetefromTn_> yeah I shot in the military as well of course
[21:30:07] <R2E4_> Big Boobs and nice accent.
[21:30:10] <zeeshan> rofl
[21:30:48] <Duc> canadian woman were hot
[21:31:08] <PetefromTn_> I shot marksmen pistol and sharpshooter rifle...I am not that great with a pistol
[21:31:18] <zeeshan> guns are heavy
[21:31:24] <zeeshan> *rfiles
[21:31:34] <Duc> I suck at shooting but own 8 1911's for some reason
[21:31:42] <zeeshan> those can be light
[21:31:54] <zeeshan> i dont understand why rim fire bullets exist?
[21:32:01] <zeeshan> seems like a dumb design
[21:32:04] <zeeshan> asking for an accident
[21:32:07] <PetefromTn_> I can hit what I need to but in competition I did not do near as well with the pistol as I do with the rifle
[21:32:15] <R2E4_> They had 9mm back when I was in. dont know what they carry now.
[21:32:33] <PetefromTn_> we shot 9mm Beretta 92fs
[21:32:43] <Duc> Cheap and a blast to shoot. 3cents per round for rim fire but 35 cents for 9mm
[21:32:56] <zeeshan> PetefromTn_: isn't that why you would expect?
[21:33:01] <PetefromTn_> there have been bazillions of rimfire rounds shot without incident
[21:33:06] <zeeshan> the rifle has a longer barrel so it helps guide the bullet?
[21:33:10] * zeeshan doesn't know shit
[21:33:16] <zeeshan> why = what
[21:33:18] <R2E4_> Pete, I got the motors to turn last noight....\
[21:33:19] <PetefromTn_> well comparatively I mean
[21:33:29] <PetefromTn_> R2 great man
[21:33:40] <PetefromTn_> I have been playing with My DMM servos
[21:33:51] <PetefromTn_> hopefully I will be running here soon myself
[21:33:56] <zeeshan> In 2007 and 2008, Canada donated 2,500 surplus C7 rifles to the Afghan National Army.[18] In 2011, the ANA gave back the C7s since the Afghan security forces chose the American M16 instead. Canadian Forces officials said the Canadian rifles would be shipped to Canada for disposa
[21:33:58] <R2E4_> Didnt change the ferror, it was too small.
[21:34:01] <PetefromTn_> what motors and drives did you use again?
[21:34:03] <zeeshan> that's how bad our c7 rifles are
[21:34:07] <zeeshan> even the afghans dont want em
[21:34:13] <zeeshan> for free. haha
[21:34:14] <Duc> lol
[21:34:28] <R2E4_> Forgot to increase it, DRO's didnt move, encoder issues I have to figure out.
[21:34:49] <PetefromTn_> huh
[21:34:57] <R2E4_> Big ass mo fo's for a CNC router, Chineese 1500 watt
[21:35:04] <PetefromTn_> so you did change the ferror or you didn't?
[21:35:14] <PetefromTn_> HOLY CRAP?
[21:35:21] <PetefromTn_> 1500 watt for a router?
[21:35:38] <Duc> dam is the structure strong enough for the force
[21:35:41] <R2E4_> yeah brought it to 1, and the motors moved, no control cause the encoders were registering.
[21:36:11] <PetefromTn_> so they ran away/
[21:36:13] <R2E4_> Its a monster 5 X 12 table out of 4" tube and 3060 extrusion
[21:36:29] <Duc> ah
[21:36:36] <R2E4_> Did have the roller pinion nexgen connected so nothing moved.
[21:36:39] <PetefromTn_> you running duals on the long axis?
[21:36:44] <R2E4_> yes
[21:36:48] <PetefromTn_> jeez
[21:36:57] <PetefromTn_> that is massive overkill I would think
[21:36:57] <Duc> what size spindle
[21:37:09] <R2E4_> 3kw chineese for now.
[21:37:33] <Duc> uh a smaller motors could have been used then
[21:37:42] <Duc> direct drive or gear reduction?
[21:37:52] <R2E4_> The Gantry is 350 lbs\
[21:38:05] <PetefromTn_> you running rack and pinion?
[21:38:13] <R2E4_> Planetary gears 10:1 I think they are
[21:38:29] <R2E4_> Rack and roller pinion
[21:38:38] <PetefromTn_> man
[21:38:59] <Duc> shit
[21:39:01] <R2E4_> https://search.yahoo.com/yhs/search?p=nexgen+roller+pinion&ei=UTF-8&hspart=mozilla&hsimp=yhs-002
[21:39:06] <PetefromTn_> I have never built one but I would think that is way more motor than you need
[21:39:34] <PetefromTn_> hey thats a nice rack and pinion setup
[21:39:43] <R2E4_> Thats what the guy wanted. I built it with 925 oz/in steppers, I told him they wouldnt be strong enough.
[21:40:05] <Duc> I know my plasma table gantry weights 100lbs and uses 620 oz/in motors with 3:1 gearing
[21:40:10] <Duc> freaking zips
[21:40:12] <PetefromTn_> on a big table like that I would want servos just for the speed of it
[21:40:17] <R2E4_> So he researched and bought everything, I made the pieces for him on my VMC
[21:40:29] <R2E4_> HE has got servos now
[21:40:31] <PetefromTn_> nice
[21:40:39] <PetefromTn_> yeah I know
[21:41:31] <R2E4_> His spindle wont be strong enough. IT will be ok, but if he had a real spindle, damn that wpuld be nice. He is goping to upgrade and have me build a topol changer for him.
[21:42:24] <PetefromTn_> it should rip pretty good with that kind of power which will be really nice on a router. moving across 12 feet should be quick
[21:43:20] <R2E4_> Yeah, he wont have any problem.
[21:43:38] <R2E4_> drivers for them, going to make a plasma cutter.
[21:44:09] <R2E4_> All the brackets for the car I am building would be nice with a plasma cutter instead of a mill....lol
[21:45:24] <Duc> for plasma setup, you cant beat a CandCNC setup for the torch height control
[21:46:04] <PetefromTn_> I think mesanet makes something for that
[21:47:49] <Duc> maybe but for ease of setup I would do CandCNC again in a heatbeat. beats torchmate systems
[21:49:46] <PetefromTn_> I think I just bought a kennametal turning and facing tool with inserts for a great price.... WOOHOO FIRST LATHE TOOL FOR THE CNC!!
[21:49:49] <R2E4_> yeah, I dont know what I am going to do for THC yet
[21:50:23] <R2E4_> ooooh, Im jealous. I want a CNC Lathe
[21:51:09] <PetefromTn_> I can't wait to be able to use this thing
[21:51:17] <R2E4_> Does the CandCNC take control of the Z?
[21:51:18] <PetefromTn_> I am still ordering parts here tho hehe
[21:51:34] <R2E4_> you buy Teco servos and drives again?
[21:52:27] <PetefromTn_> no actually
[21:52:36] <PetefromTn_> I went with the DMM tech servos from canada
[21:52:59] <Duc> Full control of Z
[21:53:17] <R2E4_> Yeah, I just checked, its 1,100.00 for the 3000.
[21:53:44] <R2E4_> Pete, you put your hands in harms way with canadian Products? lol
[21:53:47] <Duc> Can program sheetcam to lockout Z movement on corners, adjust speed of Z, slow down a percentage in the corners but requires mach3.
[21:53:48] <PetefromTn_> whats a 3000?
[21:54:17] <R2E4_> Torch height control
[21:54:18] <PetefromTn_> LOL at Canada comment
[21:54:46] <R2E4_> Mach who>?
[21:55:23] <R2E4_> I wouldnt trust Mach3 to run my conveyor.
[21:55:57] <PetefromTn_> hehe
[21:56:02] <Duc> Ive had no issues with the plasma table.
[21:56:22] <R2E4_> http://candcnc.com/index.php/plug-n-run/mp3000-dthc-series/mp3500-dthciv-ethercut-61-detail
[21:56:28] <R2E4_> The penguion is on the box
[21:56:32] <Duc> The plugin for mach3 works like a champ for CandCNC.
[21:56:49] <PetefromTn_> woohoo penguin FTW!!
[21:57:00] <Duc> dam thats new
[21:58:32] <R2E4_> I was thinking of this one.... https://www.fastcutcnc.com/cutting-tables/accessories/torch-height-control/
[22:00:01] <Duc> Just go with CandCNC believe me
[22:00:16] <PetefromTn_> http://store.mesanet.com/index.php?route=product/product&product_id=128
[22:00:52] <R2E4_> No way......
[22:01:05] <Duc> Shit what is the custom cost from South Korea?
[22:02:40] <PetefromTn_> https://www.facebook.com/photo.php?fbid=10204536202675426&set=pcb.957895884280548&type=3&theater
[22:02:54] <R2E4_> I would imagine The DAC into analog input on 7i77 would work with that mesa THC
[22:03:26] <PetefromTn_> I would think so but I would ask PCW about it. I am sure if it says mesanet on it it is probably kick ass...
[22:03:47] <R2E4_> pete, that link doesnt work.
[22:04:03] <R2E4_> PCW around?
[22:04:33] <R2E4_> Gots to be something else needed with that THC
[22:05:32] <PetefromTn_> yeah like I said I don't know how it works. I have not built my plasma cutter....YET
[22:08:25] <Duc> What cutter will you be going with
[22:08:25] <PetefromTn_> http://www.ebay.com/itm/NEW-KENNAMETAL-MDJNL-123B-3-4-SHANK-INDEXABLE-TURNING-TOOL-HOLDER-/381455688774?hash=item58d087e446:g:LGAAAOSw-vlVnqzp
[22:08:29] <PetefromTn_> just got one like that
[22:09:32] <R2E4_> It says I quit....
[22:10:10] <PetefromTn_> huh?
[22:10:20] <R2E4_> Your gonna put that in your CNC Lathe?
[22:10:31] <PetefromTn_> yeah why?
[22:10:34] <Duc> I would recommend a Hypertherm plasma cutter
[22:10:48] <R2E4_> I already have one
[22:10:54] <Duc> What size
[22:11:13] <R2E4_> I have one like that Pete. I use it on my conventional
[22:12:19] <R2E4_> Pro-cut 85
[22:12:37] <R2E4_> Just checked, lincoln pro-cut 85
[22:13:56] <Duc> ah havent dealt with lincoln cutters but I wont touch a Cutmaster again. I do enjoy the Powermax65
[22:14:46] <R2E4_> Pete: I was thinking on putting two axis on my Colchester student conventional lathe.
[22:15:32] <PetefromTn_> honestly if the lathe is large enough and precise enough for your needs I say why not?
[22:16:03] <PetefromTn_> my lathe was born a CNC lathe but I ALMOST CNC'd my asian 12x36 before I got this Standard Modern CNC lathe
[22:16:15] <Duc> Time to call it a night
[22:16:19] <Duc> work starts early
[22:17:06] <R2E4_> http://www.ebay.com/itm/MAZAK-SLANT-TURN-40N-X1500-CNC-LATHE-NR/191678920981?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20131003132420%26meid%3D0802c55a1c5c449da1be852dacf660c8%26pid%3D100005%26rk%3D1%26rkt%3D6%26sd%3D201457973177
[22:17:13] <R2E4_> Thats what I want
[22:17:56] <PetefromTn_> yeah that's what I want too but I doubt I could power it here
[22:19:34] <zeeshan> FUCK! finally!!!!!!!!!!
[22:19:36] <zeeshan> results make sense
[22:19:38] <PetefromTn_> https://uwaterloo.ca/engineering-machine-shop/sites/ca.engineering-machine-shop/files/styles/field-slideshow-slide/public/uploads/images/0109.jpg?itok=MCsRTpjg This is what my machine looks like
[22:19:41] * zeeshan apologizes for the excitement
[22:19:50] <zeeshan> you dont have that box?
[22:19:56] <zeeshan> that'd be sweeeeeeeeeeeet for a computer
[22:20:07] <PetefromTn_> nope
[22:20:13] <zeeshan> do you have that sliding cover
[22:20:15] <PetefromTn_> I think its kinda ugly tho
[22:20:25] <PetefromTn_> yeah I have the sliding cover and most of the enclosure
[22:20:28] <zeeshan> it would be ugly with a lcd screen1 :D
[22:20:31] <zeeshan> nice dude
[22:20:35] <zeeshan> i can't wait to see this
[22:20:44] <zeeshan> do you have a chuck on it?
[22:20:48] <zeeshan> (collet chuck)
[22:21:03] <PetefromTn_> no there is no chuck at all unfortunately
[22:21:07] <R2E4_> Thats cool Pete. What did you pay foir it if you dont mind me asking
[22:21:14] <zeeshan> what kind of mounting?
[22:21:14] <PetefromTn_> $500
[22:21:18] <zeeshan> jesus
[22:21:19] <zeeshan> haha
[22:21:22] <R2E4_> JEEZ!!!!!
[22:21:25] <PetefromTn_> I THINK it is a D1-5
[22:21:36] <zeeshan> okay so something you can get a backing plate for easily
[22:21:38] <R2E4_> They have anymore? lol
[22:21:38] <PetefromTn_> not bad huh
[22:21:54] <PetefromTn_> heh doubt it but the guy had a shitload of machines there
[22:21:55] <zeeshan> i dont blame you for selling your 12x36
[22:22:10] <PetefromTn_> honestly I wish I hadn't
[22:22:20] <zeeshan> you wont wish that when your cnc lathe is running
[22:22:20] <PetefromTn_> it would be nice to have both machines
[22:22:22] <zeeshan> =D
[22:22:46] <R2E4_> I dont think I'd sell mine. Nothing like throwing something on it and ripping a part out in 5 minutes....
[22:22:46] <zeeshan> dontcha think cnc is better than manual?
[22:22:49] <PetefromTn_> I wish I could see what kinda damn toolpost is in the picture tho ;)
[22:22:55] <zeeshan> i use the keyboard
[22:22:57] <zeeshan> to cut pasrts all the time
[22:23:04] <zeeshan> the only thing is you lose feedback from the handles
[22:23:09] <PetefromTn_> yeah on this machine I think it will be the best of both worlds
[22:23:28] <zeeshan> i was considering keeping the 12x36 in the basement and making it manual
[22:23:28] <PetefromTn_> kind of a good sized CNC /manual
[22:23:32] <zeeshan> but i didnt really see a reason to
[22:24:13] <R2E4_> I like the copntrols on the cover slide
[22:24:35] <PetefromTn_> really I kinda hate that LOL
[22:24:42] <PetefromTn_> I mean the EStop is cool
[22:24:50] <R2E4_> Thats going tobe sweet.
[22:25:03] <PetefromTn_> but I think it would be kind of difficult to control things on a cover that slides
[22:25:09] <PetefromTn_> I am hoping so
[22:25:19] <PetefromTn_> I mean the basic machine is pretty nice
[22:25:35] <PetefromTn_> and it is a helluva lot more rigid and powerful than my 12x36
[22:25:38] <zeeshan> pete
[22:25:39] <zeeshan> i found a pic
[22:25:40] <zeeshan> http://www.alliedmachinery.com/picture/standard%20modern%20cnc%20lathe%20(1).jpg
[22:25:42] <R2E4_> Nice to be able to stick your nose in there and not have to come all the way out to jog or whatever. Just reach back and go\
[22:25:45] <zeeshan> same machine., longer bed
[22:25:48] <PetefromTn_> plus the full enclosure will be nice too..
[22:25:50] <zeeshan> can you see what is on the tool post :-)))))0
[22:26:10] <PetefromTn_> yeah that is the FUTURE for me I hope
[22:26:20] <zeeshan> looks like a bolt on tool changer
[22:26:23] <zeeshan> rotary style
[22:26:27] <PetefromTn_> I have been trying to find an auto toolchanger that is reasonable priced
[22:26:54] <PetefromTn_> the only one I can find that is reasonable new is the one from microkinetics in Ga.
[22:27:01] <zeeshan> http://www.alliedmachinery.com/picture/standard%20modern%20cnc%20lathe%20(5).html
[22:27:04] <zeeshan> found a beter pic!
[22:27:28] <PetefromTn_> http://www.microkinetics.com/index.php?page=lathe1236/lathe about halfway down the page
[22:27:43] <PetefromTn_> wow
[22:27:50] <PetefromTn_> that LOOKS just like my crossslide
[22:28:11] <zeeshan> thats a beefy cross slide
[22:28:18] <PetefromTn_> GOD that would be so kickass to have on there
[22:28:38] <zeeshan> https://www.youtube.com/watch?v=GGtXVBRTZIA
[22:28:42] <zeeshan> heres a video of that machine in action
[22:28:50] <zeeshan> it shows the operation of that tool changer
[22:29:17] <zeeshan> sounds pneumatic
[22:29:31] <PetefromTn_> I have a strange machinist's hard on right now ;)
[22:30:03] <zeeshan> its painful watching that guy type commands
[22:30:06] <zeeshan> on that keyboard haha
[22:30:19] <PetefromTn_> that is so wierd that looks identical to my machine just longer
[22:30:35] <zeeshan> http://www.alliedmachinery.com/equipment/100393.html
[22:30:38] <zeeshan> its 17" swing
[22:30:44] <zeeshan> 100" c-c
[22:30:49] <PetefromTn_> yeah mine is only 14.5
[22:30:50] <zeeshan> but i bet same machine overall
[22:30:55] <zeeshan> 2.06 spindle bore
[22:31:05] <zeeshan> mt4 tailstock
[22:31:12] <zeeshan> http://www.alliedmachinery.com/equipment/100393.html
[22:31:14] <zeeshan> di-6
[22:31:22] <zeeshan> if the bore is the same, i bet yours is a di-6 also
[22:31:32] <PetefromTn_> hang on lemme measure it
[22:31:37] <PetefromTn_> I think it is smaller tho
[22:31:47] <R2E4_> Can you put a pot on a 7i77 analog input and control the spindle speed? I would think you could.
[22:31:57] <zeeshan> r2e4: yes
[22:32:07] <PetefromTn_> vfd will control speed
[22:32:08] <zeeshan> but why do you wanna do that??
[22:32:24] <R2E4_> I just saw that on that video you posted.
[22:32:36] <R2E4_> same reason that guy did.....lol
[22:32:37] <zeeshan> use the pot as an mpg input
[22:32:43] <zeeshan> and let the computer do the conversion
[22:33:04] <zeeshan> i forget if the mesa has an analog in
[22:33:11] <R2E4_> yes it does
[22:33:20] <R2E4_> its opnly 12 bit I think
[22:33:26] <zeeshan> mpg input right?
[22:33:34] <R2E4_> no
[22:33:34] <zeeshan> i think pins 16 17 18
[22:33:35] <zeeshan> oir something
[22:33:45] <R2E4_> 16,17,18,19
[22:33:55] <R2E4_> I have my mpg on 16 and 17
[22:34:12] <R2E4_> Any input canbe analog
[22:34:26] <PetefromTn_> my spindle bore is like 1.6"
[22:34:32] <zeeshan> darn
[22:34:36] <PetefromTn_> I am pretty sure it is D1-5
[22:34:38] <zeeshan> likely a different mount then
[22:34:38] <zeeshan> =/
[22:34:51] <PetefromTn_> hey thats bigger than my 12x36 ;)
[22:34:59] <zeeshan> hehe
[22:35:08] <PetefromTn_> and more than big enough for barrel work and what I want to do with it
[22:35:19] <zeeshan> being able to put a 1.5" round bar is going to be useful
[22:35:23] <PetefromTn_> man watching that video was cool
[22:35:49] <R2E4_> IS your spindle belt driven Pete?
[22:36:03] <PetefromTn_> its funny the machine looks identical to mine but it is bigger
[22:36:13] <PetefromTn_> yeah it is direct drive multi vee belt
[22:36:19] <zeeshan> http://www.machinio.com/listings/3734833-used-1995-18-x-40-standard-modern-cnc-lathe-in-chicago-il
[22:36:20] <zeeshan> hmm
[22:36:22] <zeeshan> this is another one
[22:36:24] <PetefromTn_> 7.5hp
[22:36:25] <zeeshan> w/ a 2.06 spindle bore
[22:36:40] <zeeshan> ah 18x40
[22:37:10] <PetefromTn_> wow I did not know they made that many versions of the same machine
[22:37:21] <zeeshan> from the internet
[22:37:26] <zeeshan> it seems like milltronics tood standard modern lathes
[22:37:32] <zeeshan> *took. and converted them to cnc
[22:37:33] <PetefromTn_> I'm kinda liking that pendant setup if it pivots
[22:38:29] <zeeshan> im going to miss having 36" c-c
[22:38:30] <zeeshan> =/
[22:38:35] <PetefromTn_> that is what I am considering a rectangular box with flatscreen like on my Cinci but I was going to install it on an overarm from the back electronics enclosure
[22:38:55] <PetefromTn_> yeah I know right mine is like 43 or so when I measured it
[22:39:08] <PetefromTn_> should come in handy
[22:39:11] <zeeshan> mine is 24" now =/
[22:39:12] <zeeshan> still decent
[22:39:21] <PetefromTn_> yeah it is especially for a slant bed
[22:39:29] <zeeshan> i could prolly put the driveshafts through the spindle bore
[22:39:33] <zeeshan> and work on it side by side
[22:39:40] <PetefromTn_> jeez
[22:39:45] <PetefromTn_> what is the spindle bore?
[22:39:52] <zeeshan> thats the only thring i really want the long c-c
[22:39:56] <zeeshan> 3"
[22:40:00] <PetefromTn_> not bad
[22:40:11] <zeeshan> the driveshaft on the rx7 is 3" od
[22:40:14] <PetefromTn_> I actually did a good bit of driveshaft work on my 12x35
[22:40:34] <PetefromTn_> I lengthened my shafts on my lifts for my suzuki samurais
[22:40:48] <zeeshan> nice
[22:40:48] <PetefromTn_> even welded them in place on the machine like a rotary fixture
[22:41:12] <PetefromTn_> the only thing that sucks is this machine did not come with a steady rest
[22:41:18] <PetefromTn_> so I will have to make one
[22:41:33] <zeeshan> might be able to buy one?
[22:41:36] <zeeshan> and retrofit
[22:41:37] <PetefromTn_> but I like ball bearing steadies anyway and would probably had to make one anyway
[22:41:57] <PetefromTn_> meh they're dead simple
[22:42:07] <PetefromTn_> and the Cinci will make short work of it
[22:42:32] <ssi> I need a big manual lathe
[22:42:39] <ssi> I love the sb10 for most stuff, but sometimes it's a bit small
[22:42:50] <ssi> I'd like to have an sb16 to complement it :)
[22:42:54] <R2E4_> Why are all the pold Mori Seiki lathes so expensive?
[22:42:56] <zeeshan> sb -- the company that turns in microns
[22:43:04] <zeeshan> r2e4: i k r
[22:43:11] <zeeshan> i inquired about one and i was shocked by the price
[22:43:18] <zeeshan> 28k
[22:43:18] <zeeshan> haha
[22:43:21] <PetefromTn_> Mori makes good shit but parts are stupid expensive I hear
[22:43:22] <zeeshan> 1980 machine
[22:45:32] <PetefromTn_> I was thinking of getting a nice wedge type aloris and a bunch of holders until I can get an auto changer on the lathe but can you guys tell what kind of toolpost that lathe has in zeeshans first link?
[22:47:08] <R2E4_> DAMN...
[22:47:09] <R2E4_> http://www.kijiji.ca/v-business-industrial/laval-rive-nord/tos-lathe-model-su-63-under-power/1031060078?enableSearchNavigationFlag=true
[22:47:45] <R2E4_> 132" 28"swing, 3000.00
[22:48:20] <PetefromTn_> that auto changer on that standard modern lathe kicks ass....I am surprised at how fast it indexes
[22:48:22] <R2E4_> Thats a monster
[22:49:20] <zeeshan> http://www.kijiji.ca/v-commercial-industriel/laval-rive-nord/iso40-cat40-arbor-lot-de-60/1073429474?enableSearchNavigationFlag=true
[22:49:23] <zeeshan> wow thats a lotta hjolders
[22:49:24] <PetefromTn_> microkinets wants 2k for their auto changer
[22:49:26] <zeeshan> too bad theyre mostly useless
[22:49:26] <zeeshan> lol
[22:49:53] <zeeshan> this guy musta had an obsession with slitting saws
[22:50:17] <ssi> PetefromTn_: microkinetics is right down the street from my h ouse
[22:50:30] <PetefromTn_> yeah I know got any pull ;)
[22:50:57] <zeeshan> have you guys heard of a company called axyz?
[22:50:59] <zeeshan> they make large routers
[22:51:05] <PetefromTn_> you should check out that toolchanger for me if you get a chance lOL
[22:51:26] <PetefromTn_> everybody and thier brothers mother make CNC routers nowadays
[22:51:40] <zeeshan> these guys have been around for a while
[22:51:42] <zeeshan> but ive never heard of em
[22:51:47] <zeeshan> i was looking up their industry profile
[22:51:52] <zeeshan> 60 million in sales a year
[22:51:55] <zeeshan> i applied for a job there
[22:52:15] <zeeshan> was a bit weary to apply there because of the reason you stated
[22:52:29] <ssi> PetefromTn_: nah sry :)
[22:52:49] <PetefromTn_> gee thanks
[22:52:55] <PetefromTn_> :D
[22:53:04] <ssi> can't help that I have no pull
[22:53:06] <ssi> I'm just not likeable
[22:53:14] <PetefromTn_> I know right!
[22:54:05] <ssi> I got more snapon crap in the mail today :P
[22:55:00] <PetefromTn_> man watching that video is like a porno for me hehe
[22:56:10] <PetefromTn_> what did you get now?
[22:57:40] <PetefromTn_> whats a good name in inexpensive SSD?
[22:57:58] <R2E4_> could get this for 2000 I am sure.
[22:58:15] <PetefromTn_> that is a big bitch man...
[22:58:50] <R2E4_> I have 600 3 phase 200 amp in my shop, and I have room....lol
[22:58:59] <ssi> PetefromTn_: more angle wrenches :P
[22:59:02] <PetefromTn_> JEALOUS
[22:59:08] <PetefromTn_> nice man
[22:59:15] <PetefromTn_> whats a good hard drive SDD
[22:59:24] <ssi> I have spare set of standard combination wrenches and standard angle wrenches, they're for sale :)
[22:59:31] <ssi> honestly anything you can get your hands on
[22:59:33] <ssi> amazon up something cheap
[22:59:53] <PetefromTn_> I am buying most of the PC stuff from newegg just need a name
[23:00:01] <ssi> any name brand
[23:00:11] <ssi> kingston, crucial, samsung, intel, ocz
[23:00:49] <ssi> someone please tell me how to convince cmake that I really actually do have wxwidgets installed thank you very much!
[23:00:52] <ssi> :(
[23:01:05] <R2E4_> http://www.kijiji.ca/v-business-industrial/ottawa/hitachi-seiki-hitec-turn-40-s-cnc-lathe/1054571645?enableSearchNavigationFlag=true
[23:01:12] <R2E4_> What kind of chuck is that?
[23:02:11] <PetefromTn_> looks like some sort of custom jaws
[23:02:16] <PetefromTn_> on a hydro chuck
[23:02:25] <ssi> yea machinable step jaws
[23:03:38] <PetefromTn_> http://www.newegg.com/Product/Product.aspx?Item=N82E16820721107&cm_re=sdd_hard_drive-_-20-721-107-_-Product any good?
[23:05:42] <PetefromTn_> http://www.newegg.com/Product/Product.aspx?Item=N82E16820156064&cm_re=sdd_hard_drive-_-20-156-064-_-Product
[23:08:38] <PetefromTn_> which of those two would you get?
[23:09:20] <ssi> the crucial is a much better value
[23:09:30] <ssi> but honestly for a linuxcnc machine both are horrible overkill
[23:09:45] <PetefromTn_> really? what would you recommend?
[23:10:15] <PetefromTn_> I'm trying to order the PC stuff tonight before i head to bed ;)
[23:10:30] <PetefromTn_> still don't know which picopc power supply to get
[23:10:42] <Valen> it depends on if you are going to use it for other stuff
[23:10:51] <PetefromTn_> such as
[23:10:54] <ssi> get the crucial
[23:11:01] <ssi> apparently newegg doesn't sell anything small/cheap
[23:11:14] <PetefromTn_> I thought that WAS small and cheap :D
[23:11:18] <Valen> surfing the net, reading gigaquads of email
[23:11:20] <ssi> 240G is effing massive
[23:11:25] <ssi> I use 32G ssds for my machines
[23:11:27] <Valen> yeah its hughe
[23:11:34] <ssi> 240G is as big as every ssd I have in my primary development workstations
[23:11:37] <PetefromTn_> is that bad?
[23:11:41] <ssi> no, it's not bad
[23:11:43] <ssi> it's just overkill
[23:11:44] <Valen> no, just more than you need
[23:11:51] <Jymmm> ssi: Send be your handmedown SSD's =)
[23:11:54] <Valen> like having a 300 liter fuel tank in your car
[23:11:58] <PetefromTn_> Ok most of the ones they sell are at least 120
[23:12:04] <ssi> Jymmm: my handmedowns go in cnc machines
[23:12:07] <Valen> without it taking up any extra room
[23:12:07] <PetefromTn_> and they are not much cheaper
[23:12:15] <ssi> PetefromTn_: I paid $500 for my first 120g ssd
[23:12:26] <PetefromTn_> i know amazing how cheap they are now
[23:12:36] <Jymmm> 4Gb SSD would be fine
[23:12:38] <Valen> I'd get the 240 for the extra $15, it'll be more useful when you put it in something else later ;->
[23:12:38] <PetefromTn_> but the crucial is a good name
[23:12:43] <ssi> yes
[23:12:46] <Valen> kingston are ok too
[23:12:54] <ssi> the crucial is a better deal
[23:13:00] <Valen> NO!
[23:13:02] <Valen> its 2nd hand
[23:13:07] <PetefromTn_> just because its bigger or for other reasons
[23:13:07] <ssi> is it?
[23:13:10] <Valen> I thought it was too good to be true
[23:13:13] <Valen> "refurbished"
[23:13:14] <ssi> yeah seriously
[23:13:17] <Valen> just spotted that
[23:13:35] <PetefromTn_> oh yeah it is..
[23:13:39] <Valen> probably shagged out from being in somebodies big server environment
[23:13:45] <ssi> most of the time refurb doesn't scare me
[23:13:45] <Valen> get the kingston then ;->
[23:13:48] <ssi> but on SSDs it does :)
[23:14:06] <Valen> yeah, anything other than ssd/hdd refurb is probably fine
[23:14:44] <Valen> $50 is going to be cheaper than spinning rust isn't it anyway?
[23:15:16] <ssi> probably
[23:15:24] <ssi> and I'm not a fan of platter drives in cnc machines
[23:15:32] <ssi> cnc machines are embedded environments as far as I'm concerned
[23:16:57] <PetefromTn_> the kingston is new i think
[23:17:02] <Valen> yeah it is
[23:17:04] <ssi> yes that's fine get it
[23:17:11] <ssi> push order and go to bed :)
[23:17:14] <Valen> I have one of those sitting in my car at the moment waiting to go into a computer
[23:17:30] <Valen> like that exact model
[23:17:34] <Valen> and one in my tv
[23:17:41] <Valen> and one in my dads tv computer
[23:17:45] <PetefromTn_> sweet
[23:18:03] <PetefromTn_> does newegg sell those picopc supplies?
[23:18:34] <ssi> if only they had some kind of box where you could type in the name of a thing you wanted and it would tell you whether they had it
[23:18:40] <PetefromTn_> maybe I am spelling it wrong
[23:18:44] <ssi> picopsu
[23:18:50] <PetefromTn_> ah
[23:19:08] <PetefromTn_> such a smartass ;)
[23:19:54] <ssi> do I need to tuck you in tonight too? :D
[23:20:20] <PetefromTn_> kiss it.... apparenlty they only sell the 12v models not the variables
[23:20:52] <ssi> tuck you in AND kiss it?
[23:20:57] <ssi> I draw the line at reading you a story
[23:21:24] <PetefromTn_> if you were not so helpful you would be quite an annoyance ;)
[23:21:54] <Valen> I wouldn't bother tbh unless you have super small space requirements
[23:22:18] <PetefromTn_> I want this because I want to run the PC from my machines 24v power supply
[23:22:21] <ssi> Valen: it's less the space requirements and more the hassle of mounting a pc psu in an enclosure, and the wiring and crap
[23:22:43] <Valen> I'd really want to keep the PC and machine supply seperate
[23:23:03] <Valen> machine supply has phat motors hanging off it and the like
[23:23:16] <ssi> no motors on the 24v bus
[23:23:24] <ssi> just field io, relays, etc
[23:23:25] <Valen> "all the wiring and crap" lol mains in and ATX out ;->
[23:23:51] <Valen> relays are not nice ;->
[23:24:00] <ssi> I mean this wiring and crap
[23:24:00] <ssi> http://powersupply33.com/wp-content/uploads/2011/07/atx-power-supply-connectors.jpg
[23:24:17] <ssi> it's cluttery and annoying
[23:24:26] <Valen> I do like the idea of being able to just turn the PC on and use it without turning the machine on
[23:24:52] <PetefromTn_> I do that all the tmie
[23:24:53] <PetefromTn_> time
[23:24:59] <Valen> same
[23:25:09] <PetefromTn_> but I don't think this would prohibit that
[23:25:23] <PetefromTn_> servos etc would be disabled until called for
[23:26:13] <ssi> dammit I really wish I had logging turned on in irssi :(
[23:26:21] <ssi> Sync: you still alive?
[23:26:31] <ssi> probably not, it's freakin 6am over there
[23:27:07] <PetefromTn_> well I can't get the pico thing from newegg unfortunately
[23:27:21] <PetefromTn_> they do not seem to even carry the variable input voltage models
[23:28:03] <PetefromTn_> so I got the main board/cpu combo, DMM ram and SSD
[23:31:33] <PetefromTn_> shit I guess because newegg has a port in memphis I gottta pay tax
[23:37:17] <PetefromTn_> Sweet PC stuff is on the way
[23:37:30] <PetefromTn_> now its bed time ;) Gn8 guys
[23:53:57] <ssi> PCW: hm2/hm2_5i25.0: hm2_sserial_waitfor: Timeout (25mS) waiting for addr 5a00 &mask ffffffff val 1004
[23:54:07] <ssi> PCW: what's the significance of 5a00 or 1004 there?
[23:54:16] <ssi> are either of those addresses in the remote memory space it's trying to read?
[23:54:32] <ssi> next line: hm2/hm2_5i25.0: DATA addr 5b00 after timeout: 0
