[00:03:55] <jdhNC> that looks good
[00:04:05] <jdhNC> the probe move is way too fast though
[00:04:46] <Tom_itx> well slow it down
[00:05:00] <Tom_itx> jog down to 'close' then slow it down
[00:05:30] <jdhNC> need to wire up the probe, such as it is first
[00:06:09] <Tom_itx> i was gonna use a piece of pcb for my tools i think
[00:06:32] <Tom_itx> haven't completely decided yet
[00:07:00] <jdhNC> do you know if the probe should be normally open or closed?
[00:07:17] <Tom_itx> i know how i wired it
[00:07:38] <Tom_itx> the touch probe is NC
[00:07:51] <Tom_itx> your tool would be NO
[00:08:06] <Tom_itx> unless you short it

[00:09:21] <atom1> net touch-probe hm2_[HOSTMOT2](BOARD).0.gpio.038.in => motion.probe-input
[00:09:38] <jdhNC> I was thinking an alligator clip on the tool going to +5, the board wired to the probe input with a 2.2k to ground?
[00:10:05] <Tom_itx> unless your machine is grounded
[00:10:14] <Tom_itx> which it should be
[00:11:11] <Tom_itx> your steppers or servos should be grounded which would ground the machine to the electronics
[00:11:14] <Tom_itx> probably
[00:11:36] <Tom_itx> i would still run a wire to the tool
[00:15:01] -!- atom1 has quit [Quit: Leaving]
[00:16:30] <jdhNC> the endmill doesn't appear to be grounded
[00:16:44] <jdhNC> this router has lots of plastic parts
[00:16:47] <Tom_itx> not sure i'd rely on that
[00:16:55] <Tom_itx> but give it a go if you want
[00:17:46] <jdhNC> heh, gotta look for a spare input first.
[00:18:37] <jdhNC> I haven't looked at the config in 6 months and forgot what everything does

[01:17:23] <jdhNC> that looks like what I really want to do though.
[01:18:19] <Tom_itx> you looked at the gcode stuff in eagle?
[01:19:36] <jdhNC> not really
[01:21:48] <Tom_itx> i modded one for my sherline for drilling
[01:21:52] <Tom_itx> but i don't use it much
[01:22:05] <Tom_itx> there's a couple there

[01:36:30] <jdhNC> I have two boards I want to make, but I did them in autocad then cut2d
[01:36:58] <Tom_itx> seems like alot of work for a board
[01:37:18] <Tom_itx> i didn't have much luck milling boards
[01:37:22] <Tom_itx> my spindle is too slow
[01:37:28] <jdhNC> I might not either
[01:37:38] <Tom_itx> and i found it cheaper just to etch or have them made
[01:37:42] <jdhNC> but, they aren't very complicated.
[01:38:03] <Tom_itx> you were asking about pcb weren't you?
[01:38:08] <Tom_itx> did you find some?
[01:38:21] <jdhNC> yeah, I got some 2oz single sided
[01:38:38] <jdhNC> is there a relatively easy way to display the probed height?
[01:38:54] <Tom_itx> no idea, i haven't gotten that far along yet

[02:00:04] <Emma> Hi - can anyone help me with a newbie problem? I have a Probotix "Comet" with EMC which was working fine a couple days ago - then we updated ubuntu, and now it seems like my joystick isn't bound right
[02:00:43] <Emma> I get this message in the emc debug screen "custom_postgui.hal:23: Pin 'input.0.btn-trigger' does not exist"
[02:01:44] <Emma> the logitech joystick is plugged into the USB port - and found under devices
[02:01:46] <Emma> thx,

[02:07:26] <Tom_itx> guess not
[02:07:38] <jdhNC> heh
[02:07:43] <jdhNC> short attention span
[02:09:44] <jdhNC> I can make it display a message, but it says #5063 instead of the value of #5063
[02:10:03] <Tom_itx> i haven't gotten into that stuff yet
[02:10:12] <Tom_itx> i'm sure you can
[02:12:09] <jdhNC> (debug, Probe found #5063)
[02:15:34] <jdhNC> any guess how thick 2 oz copper is?
[02:18:18] <Tom_itx> .062"
[02:18:34] <A2Sheds> just the copper?
[02:18:39] <Tom_itx> no
[02:18:41] <jdhNC> I meant just copper
[02:18:46] <Tom_itx> not sure
[02:18:53] <A2Sheds> http://www.standardpc.com/laminates.htm
[02:19:22] <Tom_itx> peel a corner back and measure it
[02:20:44] <jdhNC> A2: nice ref, thanks.
[02:22:04] <A2Sheds> if you're working with controller impedance or controlled dielectrics then you really have to check with the board house and their supplier of core and prepreg

[07:55:46] <Quack_> although we do have dry weather
[07:55:57] <mrsun> Quack_, im thinking more in the ways that your mother doesnt have a choice anymore :P
[07:56:01] <Quack_> i guess i could create a shed for it
[07:56:07] <Quack_> hahaha
[07:56:38] <Quack_> i don't recall talking to you before
[07:56:43] <Quack_> but perhaps you had seen my conversations
[07:56:57] <mrsun> yeah, at 05:49 :P
[07:57:44] <Quack_> oh ok lol
[07:57:53] <Quack_> where you at Mr Sun?
[07:59:05] <Quack_> where are you located?
[07:59:32] <mrsun> sweden
[08:00:55] <Quack_> ahh ok
[08:01:11] <Quack_> in sweden things rust faster
[08:01:56] <mrsun> yeah, they do =)
[08:02:12] <mrsun> atleast this time of year its horrible
[08:02:19] <mrsun> nothing dries ... ever :P
[08:05:48] <Quack_> that's why they made volvos with a lot of metal
[08:05:56] <Quack_> proud volvo owner here
[08:06:24] <Quack_> anyways i wish i lived in europe....probably access to more used machine equipment
[08:07:13] <psha[work]> mrsun: you still have autumn? or winter already?
[08:08:48] <Quack_> i wanna live in sweden so bad so i can go to all the shout out louds concerts i can
[08:09:37] <mrsun> psha[work], meterological autumn or whatever still
[08:09:46] <mrsun> last year this time we had like half a meter of snow :P
[08:10:00] <mrsun> this year im still pouring concrete every day and it manages to harden =)
[08:10:15] <psha[work]> we've got ~20 degrees diff in two days :]
[08:10:19] <psha[work]> from +5 to -15 :]
[08:10:22] <psha[work]> and no snow
[08:10:44] <mrsun> psha[work], in the end of this month they say that snow is comming, but then im done with the concrete and it has harden for a week or two so i will be on the green =)
[08:11:18] <mrsun> (restoring a barn and want the foundation done before winter so ic an do over dirt work in the winter) =)
[08:12:14] <Quack_> haha cool
[08:17:11] <mrsun> i think the gods are smiling at me this year cause ive hand dug like 8 cubic meters of dirt inside of it, so they are just thinking "hell, well let him get it done before we crank the airconditioner on"
[08:20:40] <Quack_> i think i would love sweden
[08:20:42] <Quack_> tons of snow
[08:31:10] <mrsun> snow is beautifull yes, but its to much of it :P
[08:31:18] <mrsun> and so freakin dark in the winter
[08:31:32] <mrsun> ok not that dark thatnks to all the snow but :P
[08:35:06] <Quack_> hot girls in sweden tho?
[08:41:28] <mrsun> i guess :P
[08:41:35] <mrsun> you know, people get home blind :P
[08:41:40] <mrsun> i think girls are prettier in other places :P

[10:32:16] <cncbasher> yes you should be able to , but some of the real cheap drill presses do not use angle type bearings , so you end up modifying or changing the bearings
[10:32:35] <cncbasher> sometimes it's just not worth it
[10:33:41] <Valen> where would one find cheap "servo" motors
[10:35:41] <cncbasher> cheap and servo motors do not go together in the same sentence -- ebay perhaps ?
[10:36:07] <cncbasher> what are you lookiing for ?
[10:37:52] <cncbasher> i use servo-uk.co.uk for mine , but i would not say they are cheap
[10:38:39] <awallin> keling? (fit your own encoder..)
[10:39:03] <awallin> http://www.kelinginc.net/ServoMotors.html
[10:39:08] <mrsun> cncbasher, hmm that sucks =)
[10:40:48] <Valen> i'm looking for cheap ;->
[10:41:05] <awallin> surpluscenter / ebay / ..
[10:41:07] <Valen> i cant work out why they are so expensive in comparison to a generic dc motor
[10:41:46] <cncbasher> mrsun> yea i have ended up boring castings before today to fit larger bearings , but it's not always possible
[10:45:38] <mrsun> ough, cold weather is comming according to the forecasts, and the concrete needs 2 or 3 days to be safe from freezing ...
[10:45:49] <mrsun> damn this is going to be right on the edge of that :P
[10:45:55] <mrsun> and id ont want to redo it in the spring :P
[10:45:57] <awallin> normal dc motors might have 'cogging' i.e. the shaft jumps from one position to another when you rotate it. proper servos should have a twisted rotor to minimize cogging.
[10:45:59] * anonimasu orders inserts
[10:47:31] <anonimasu> seems like it's economical to buy better insert grade for turning then CP500, like TP2500 if you dont intend to turn aluminium

[11:19:27] <elmo40> our shop mainly turns castings and hardened steels. in my experience every grade fails too quickly :-p
[11:20:49] <elmo40> the intermittent cuts cause premature wear. did i mention we also turn flame cut parts? and large dia sleeves that are welded?
[11:21:01] <elmo40> i go through inserts like no tomorrow. doesnt matter the grade
[11:21:39] <elmo40> hitting a weld that is .400" larger then the part really pushes on that tool.
[11:23:26] <elmo40> in a good setup i can cut 0.450" rough cuts! 2" holder and 5/8" inserts. The chips coming off of it are damn hot, they affect the tolerance in the carriage by heating it up. Even coolant doesnt control it.
[11:24:03] <syyl> sounds like fun ;)
[11:25:20] <elmo40> it is :)

[17:15:16] <Rogge> Hello all -
[17:16:26] <Rogge> QUick lathe/spindle encoder question for you
[17:16:26] <Rogge> I've got an encoder mounted off the toothed drive belt to the spindle
[17:16:26] <Rogge> Encoder counts per spindle revolution is 235.3475
[17:16:26] <Rogge> All is well, save mulitpass threading
[17:16:42] <Rogge> The index pulse that EMC wants apparently must be once per spindle rev.
[17:17:14] -!- SWPadnos_ [SWPadnos_!~Me@74-92-8-208-NewEngland.hfc.comcastbusiness.net] has joined #emc
[17:17:14] <Rogge> I've seen a hal component that will handle this (http://www.franksworkshop.com.au/EMC/comp/enc_idx_div.comp)
[17:17:24] <Rogge> But I'm thinking there must be an easier way?
[17:18:42] -!- mhaberler [mhaberler!~mhaberler@178-191-62-1.adsl.highway.telekom.at] has joined #emc

[17:20:22] SWPadnos_ is now known as SWPadnos
[17:21:03] <cradek> I don't have a direct answer but would like to see what you've got. do you have a photo of the setup?
[17:21:03] -!- mhaberler has quit [Client Quit]
[17:23:21] <Rogge> Here's the photo: http://static.inky.ws/image/797/image.jpg
[17:23:59] <archivist> I imagine a real hardware index pulse would be better as you dont have an integer no of pulses per rev
[17:24:13] <Rogge> Actually, looking at that hal comp that I linked to earlier, it wouldn't work for my case.
[17:24:49] <Rogge> I would imagine that on larger bore lathes it gets harder and harder to couple an encoder in a 1:1 ratio?
[17:25:18] <cradek> what is the other outer pulley for?
[17:25:36] <cradek> looks like you could turn the encoder around and match that tooth count
[17:25:40] <Rogge> The blunt force way around this is to throw out the Z signal from the encoder and mount a prox sensor and flag on the spindle.
[17:26:15] -!- mhaberler [mhaberler!~mhaberler@178-191-62-1.adsl.highway.telekom.at] has joined #emc
[17:26:25] <Rogge> Matching the tooth count would be hard on that dinkly little encoder shaft.
[17:26:52] <Rogge> cradek: not sure what the other pulley is for.. came on the lathe!
[17:27:26] <Rogge> Has this issue not come up for others? I know there have been some really large lathe refits on EMC, no?
[17:27:47] <pcw_home> Any of the pulleys Steel? maybe counting teeth would be easier
[17:28:23] <archivist> capacitive to the ally maybe
[17:28:33] <cradek> my lathe is 5c and getting 1:1 was easy
[17:28:38] <Rogge> pcw_home: interesting thought - but they're Al.
[17:29:06] <Rogge> cradek: how did you do it? Pulley on encoder mathed the spindle pulley?
[17:29:16] <cradek> yes exactly
[17:29:24] <Rogge> Do you have a photo?
[17:29:35] <cradek> no, sorry
[17:29:39] <archivist> mine has a disk on the spindle
[17:29:42] <Rogge> no problem!
[17:29:48] <cradek> it's just what you say though. easy to envision.
[17:30:13] <Rogge> I have thought about a disk... how to you do the index? Separate sensor? Or different slot width?
[17:30:16] <cradek> looks like you could replace your back pulley with something MUCH smaller
[17:30:31] <archivist> add a slotted disk to the main pulley
[17:30:45] <Rogge> cradek: agreed... just thought I could fix it in the software
[17:31:17] <archivist> a hole somewhere on the disk dont change widths of the slots
[17:31:37] hackrat is now known as packrat
[17:31:41] <Rogge> archivist: so there are two sensors - one for the index, one for the A phase?
[17:31:46] <JT-Shop> seems like the encoder on my 16c CHNC is not 1:1 iirc
[17:31:48] <archivist> yup
[17:32:13] <Rogge> JT-SHop: any recollection on how you got multipass threading to work if the ration is not 1:1?
[17:34:28] <Rogge> Before I give up hope of a HAL component -
[17:34:43] <cradek> http://www.wallacecompany.com/cnc_lathe/HNC/00011-1a.jpg
[17:34:53] <cradek> this is someone else's solution for the same lathe I have
[17:35:01] <Rogge> It's obviously posibly if there's an integer ratio between the encoder and the spindle pulley teeth (e.g. 3:1)
[17:35:02] <cradek> you can barely see the belt
[17:35:23] <cradek> the housing and general setup is original
[17:35:45] <Rogge> Does it seem at all possible with the wacky cound that I have? I'm thinking not.
[17:36:07] <A2Sheds> anyone have a favorite optical limit or home switch for 5-12V operation?
[17:36:43] <Rogge> cradek: Yep - it looks like the belt is going to a pully of the same diameter.
[17:36:59] <Rogge> OK - I think that I'll need to fix this in the hardware, not the software.
[17:37:11] <Rogge> Thanks for the advice, all!
[17:37:25] <cradek> Rogge: you could probably do it in floating point land since you're feeding it to the motion controller (servo thread), but I would sure rather have integers
[17:37:31] <cradek> welcome, hope you find a solution
[17:38:35] <tom3p> maybe the unused outer pulley is a better candidate for integer match
[17:39:40] <Rogge> tom3p: I'll be checking!
[17:40:37] <JT-Shop> Rogge: I'm not sure but the encoder pulley looks too small for 1:1, but I guess the smart thing to do is to look in the parts manual instead of taking it apart
[17:41:07] <JT-Shop> and I may be totally full of s#!t
[17:42:01] <cradek> JT-Shop: my HNC originally had an encoder (with one channel missing) AND a resolver geared 1:1 on the spindle. I have no idea why.
[17:42:27] <cradek> so who knows what you will find on yours!

[18:39:01] <MDesade> i had to ask
[18:39:21] <MDesade> i got 8.04 loaded, and its been running its latency test all night..
[18:39:35] <MDesade> still haven'f figured why 10.04 didn't work...
[18:40:01] <MDesade> i may try to reload it on a different drive, so i don't have to repeat this again, if it doesn't work again
[18:40:19] <MDesade> usually, newer versions of linux have BETTER not worse hardware support

[18:46:48] <MDesade> and i was going to use Tiny7 or TinyXP anyway, which is optimized for the VIA m10000 board

[18:52:39] <MDesade> yep
[18:52:59] <MDesade> should be plenty of horsepower for this
[18:53:14] <JT-Shop> EMC doesn't need horsepower :)
[18:53:14] <MDesade> a gig of RAM and that should be good enough
[18:53:36] <MDesade> shit, i might even use a solid state drive just to be fancy
[18:53:47] <A2Sheds> 386 version of Ubuntu required

[18:54:41] <A2Sheds> heh I just got rid of my last VIA C7 boards
[18:54:50] <MDesade> is that the issue? is the 10.04 64 bit?

[18:57:14] <MDesade> pleae clarify
[18:57:30] <A2Sheds> MDesade: the EMC Live-CD is i386, is that the one you tried to load?
[18:57:32] <MDesade> i DO know Linux really well...
[18:57:39] <A2Sheds> MDesade: for 10.04?
[18:57:48] <MDesade> A2Sheds yes
[18:57:52] <cncbasher> touch screen works fine on the server , but client touch screen wont ltsp = pxe boot
[18:58:02] <MDesade> ah...
[18:58:28] <MDesade> for pxe boot, you need to make sure it is loading the driver and modules correctly
[18:58:38] <MDesade> not a generica kernel
[18:58:39] <cncbasher> built multitouch driver into client fine , just wont run
[18:59:05] <A2Sheds> MDesade: it;s been a few years since I had a C3 board, maybe Ubuntu has something in the kernel or RTAI that doesn't play well with the C3
[18:59:20] <MDesade> since mine is running the disk locally, i had no problems. also, i use the 3M touchscreen, and they are well supported

[19:00:26] <cncbasher> touch screen works fine in emc , just not over booting as a client
[19:00:38] <MDesade> its a gnome issue, i "assume" it is trying to load some 3d accelerated graphics card, which isnt there
[19:00:43] <cncbasher> ok thanks
[19:00:43] <A2Sheds> MDesade: ahh, ubuntu problems
[19:00:56] <MDesade> right
[19:01:03] <MDesade> 8.04 works, and installed fine
[19:01:26] <MDesade> i just need to add some ram, and she is good to go
[19:01:54] <A2Sheds> MDesade: there are $70 Atom boards that work really great with EMC :p .... save you some VIA headaches
[19:01:55] <MDesade> and, if i want to be fancy? a 32 gig SSD
[19:02:10] <tom3p> try adding vga=0x117, or drop to the grub text shell at boot and see what 'vbeinfo' says is available
[19:03:11] <MDesade> A2Sheds - id be fine with an ATOM board, as long as it's micro ATX, then i can the whole box (display, power supply, and everything in one case, and on a swing arm
[19:03:26] <A2Sheds> they are mini-itx
[19:03:42] <MDesade> yep
[19:03:58] <MDesade> and im pretty sure they support more RAM
[19:04:16] <MDesade> ok, ill look into it, and hit up frys later
[19:04:30] <A2Sheds> let me find the link
[19:05:07] <MDesade> obviously i need a parallel port
[19:05:34] <MDesade> and these are the stepper kit ill be using on the smithy cb1220xl here http://www.kelinginc.net/CNCNEMA34Package.html
[19:08:51] <A2Sheds> http://wiki.linuxcnc.org/emcinfo.pl?Latency-Test
[19:09:34] <A2Sheds> the Atom 945 boards worked great, there are some ewer Atom boards that also have great latency
[19:10:28] <MDesade> A2Sheds - excellent
[19:10:38] <MDesade> ill hit up frys...
[19:10:51] <A2Sheds> the 525 Atom boards
[19:10:54] <MDesade> i love micro-atx boards, and for this project, i think its the perfect fir
[19:10:56] <MDesade> fit
[19:11:51] <MDesade> i can build the 12.1 inch LCD, touchscreen, power supply and drive plus the motherboard into a 3inch thick case, and mount it on a swing-arm, and bam we are off to the races
[19:11:53] <A2Sheds> I'm using up my last core 2 duo 945 micro-atx board on an EMC project
[19:12:20] <MDesade> dude? a core2 is VASTLY overpowered for the EMC project
[19:12:34] <MDesade> waste of CPU cycles
[19:12:39] <A2Sheds> sure, but it's already paid for
[19:12:49] <A2Sheds> and latency is ~4K
[19:12:53] <MDesade> right, i understand that loud and clear
[19:12:57] <A2Sheds> and I'm using servos
[19:13:30] <jdhNC> and mesa?
[19:13:35] <MDesade> kinda why i was hoping this VIA would be the right fit, but? im ok with spending 70 bucks
[19:13:56] <MDesade> i can find some other embedded project for this mobo

[19:20:50] <A2Sheds> I was just looking over issues with the C3 and ubuntu, seems there were problems with x, it might have had more to do with the unichrome GPU
[19:21:14] <MDesade> A2Sheds - disco
[19:21:27] <A2Sheds> or that cpu freq scaling
[19:22:04] <MDesade> that explains alot. gnome would come up, login in, and then about 10 seconds it acts like i have a desktop loading, then it flashes black, and then regens the screen back to the login screen
[19:23:13] <A2Sheds> and fixing X in unbuntu was always a pain since "bulletproof X"
[19:23:24] <A2Sheds> mystery configs
[19:23:30] <MDesade> right
[19:23:54] <MDesade> ok, the ATOM for 70 bucks is a better solution, than hours of fixing an obscure driver issue
[19:24:04] <MDesade> ya know, what is my time worth?
[19:24:29] <A2Sheds> we had coreboot working well with the C7's and the cn700 chipset, but X was always flaky with ubuntu
[19:24:31] <MDesade> this is meant for rapid prototyping, not "screwing around for weeks" to save 70 bucks

[19:53:54] <andypugh> Does anyone have an opinion on nipple fatigue?
[19:54:15] <A2Sheds> are you nursing?
[19:54:18] <tom3p> John at Keling is pretty good to deal with. I picked my stuff up from Elgin and saved 40$ shpg.
[19:55:29] <tom3p> andypugh, grease nipples? zirc fitings?
[19:55:30] <A2Sheds> tom3p: do they have a showroom or is it just a warehouse?
[19:55:39] <tom3p> warehouse
[19:55:56] <andypugh> The Fire Engine blew it's engine up again. It was a fatigue failure of the main oil pipe nipple. (the engine has external oil pipes, so this means that the oil pump empties all the oil out on the road). I am wondering abut re-making the pipe nipples in steel, possibly stainless, rather than brass, but I am not sure which ahs the best fatigue properties.
[19:55:58] <tom3p> but he'll show you around, some nice routers
[19:58:01] <tom3p> andypugh, oh pipe nipple. short pipe, well SS is used in hi pressure, but what caused fatigue? vibration?
[19:59:10] <andypugh> Yes, vibration due to being mounted on a 9-litre 4-cylinder engine, which is rigidly bolted to a chassis suspended on stiff springs and solid rubber tyres.
[19:59:40] <andypugh> (I meant to mention the unbalanced crank there, and the >1lb difference in piston weights)
[20:00:31] <MDesade> i'm back
[20:00:40] <skunkworks> andypugh: do you have a picture of your nipples?
[20:00:43] <MDesade> A2Sheds so you are familiar with keling??
[20:00:44] <skunkworks> heh
[20:00:45] -!- capricorn_one has quit [Remote host closed the connection]
[20:00:54] <andypugh> The pipe is about 1/2" thin-wall steel, brazed into brass nipples at each end, and mounted to the oil pump at the back, and a fitting at the front.
[20:01:08] <A2Sheds> cMDesade: that supplier is near me, but I've only seen the link
[20:01:26] <andypugh> skunkworks: It looks just like any other brass solder-nipple.
[20:01:47] <MDesade> ah... ok, they we're going to supply my a smaller stepper for the Z-axis, so it will cost less than the 800 they have listed
[20:01:56] <MDesade> more like 700
[20:03:26] <A2Sheds> 9 liter 4 cyl, oh man
[20:05:10] <A2Sheds> andypugh: happen to know the bore and stroke?
[20:05:21] <Quack> 9 liter 4 cyl?
[20:05:26] <Quack> wow i hope that's a diesel
[20:05:38] <Quack> cuz otherwise it's gonna guzzle gas like no other
[20:05:51] <andypugh> skunkworks: http://www.completeautomobilist.com/m/products/2/0/3402/0unionselbow.jpg
[20:06:34] <andypugh> No, it's a petrol (Gasoline) engine. And sometimes, on a good run, if it's fairly flat and there is a follwoing wind, we can get close to 8mpg.
[20:06:38] <Quack> is machining brass less harsh on a carbide or other bit than machining aluminum?
[20:07:28] <andypugh> Quack: I am not sure. Swarf clearance is less of an issue.
[20:07:50] <Quack> swarf? what's that
[20:08:26] <Quack> can't find an exact definition on the web
[20:08:29] <andypugh> All the metal that doesn't end up in the finished part?
[20:08:29] <syyl> in my opinion, tool life in both materials is about the same
[20:08:40] <Quack> ahh ok
[20:08:44] <syyl> swarf is the metal that hides the finished product ;)
[20:08:45] <Quack> they are both soft i would imagine
[20:08:52] <Quack> brass is almost as soft as copper
[20:08:55] <syyl> brass is hard and brittle
[20:09:10] <Quack> oh it is an alloy
[20:09:38] <syyl> almost every metal you use in a shop is an alloy
[20:10:02] <Quack> ahh ok duh =p
[20:10:03] <andypugh> Indeed. It's also surprisingly strong. It needs very sharp tools (traditionally brand-new files and saw blades are used for brass, then go on to cut steel when they lose their keen edge)
[20:10:26] <Quack> so brass is harder than steel? wtf
[20:10:37] <syyl> a endmill that has seen steel wont work in brass very well
[20:10:48] <Quack> it needs to be sharp ok....
[20:11:05] <syyl> sharp as hell
[20:11:27] <andypugh> I have seen info (from the Brass Development Board, or some other body with a vested interest) saying that very often the prodictivity gains from using brass rather than Ali or steel more than made up for the increased material cost.
[20:11:59] <ds3> has anyone tried CNC'ed EDM milling?
[20:13:46] <Quack> maybe i should really just start off targeting aluminum
[20:13:53] <Quack> because steel and brass have their issues
[20:14:23] <skunkworks> aluminum has issues too... like gulling
[20:14:41] <syyl> i would go for the right material for the right job ;)
[20:14:56] <skunkworks> (sticks to the tooling... depending on the type and coolant)
[20:15:19] <andypugh> Brass is probably the easiest of them all to dry-cut
[20:15:34] <andypugh> And you always get a good finish.
[20:16:12] <A2Sheds> MDesade: Kelinginc carried lots of the same spindles and motors I see on ebay from China
[20:16:45] <Jymmm> JT-Shop: jthornton yo man
[20:17:30] <tom3p> andypugh, could you use a high pressure flex connection, those wire braid covered hoses? get rid of the transmitted vibration
[20:17:54] <A2Sheds> http://www.kelinginc.net/CNCSpindleandController.html vs http://www.ebay.com/itm/2-2KW-WATER-COOLE-SPINDLE-MOTOR-ER20-INVERTER-DRIVE-e-/250792695325?pt=LH_DefaultDomain_0&hash=item3a6468d61d
[20:18:38] <andypugh> tom3p: If the aim was to find a better engineering solution, then yes. However this is a 95 year old historic vehicle, so originality is importnat.
[20:19:01] <Quack> but then again brass is more expensive right
[20:19:06] <Quack> brass is ridiculous
[20:19:29] <tom3p> andypugh, then make 4 of 'em :)
[20:20:08] <andypugh> tom3p: The problem is that if they do break, you lose all the oil and havd a £1000 bill to re-metal all the bearings..
[20:20:25] <tom3p> check valve wouldnt be visible
[20:20:41] <tom3p> oh, doesnt help bearing, only the spill
[20:22:58] <andypugh> Yes, the pipe in question take the oil from the pump to the No1 Main, where it enters a groove machined in the bottom half-shell. There is a cross-drilled hole in the crank journal, and 4 holes in the top half-shell, to drillings and a union block and 4 more sets of external oil pipes to the other mains. That means that every engine rev every other main gets a squirt of oil. This was a White and Poppe patent.
[20:24:06] <Danimal_garage> hi
[20:24:49] <Quack> sup danimal
[20:26:42] <Danimal_garage> not much, you?
[20:28:08] <andypugh> It's a dry-sump engine, so when that pipe breaks you lose all lubrication.
[20:29:46] <A2Sheds> if you make the nipples tougher won't the vibration just cause the next weakest link to break due to fatigue, maybe the external oil lines next?
[20:30:15] <andypugh> Yes, but pushing it from 10 years to 20 years would be a win..
[20:30:19] <tom3p> andypugh, does it have to BE original or LOOK original ?
[20:30:41] <andypugh> Well, I am not going to re-use the broken one :-)
[20:32:21] <andypugh> There is some evidence that they used pipes with swaged-in ends. But I have no idea where you would find the tool to do that. It must have been a t-stage process, expanding the pipe first to make the shoulder, then squeezing back in to make the cone.
[20:32:37] <andypugh> (two-stage)

[20:33:29] <A2Sheds> can you balance the crank and pistons any better? Is that the main cause of the vibration or is it just due to being a lopey 4 cyl cam/valve timing?
[20:34:45] <andypugh> We already have balanced the pistons better. It used to be the case that one piston was 4lbs heavy.
[20:35:16] <cncbasher> andypugh> probably the same way as loco boiler tubes
[20:37:41] <cncbasher> andypugh>if you need a design of a tool i can probably find one , or raid the workshop
[20:37:47] <andypugh> Those are expanded, but not then re-crimped. I know the tools you are thinking of: http://www.youtube.com/watch?v=MzD1Otxj6nE
[20:39:12] <andypugh> I guess you could do something very similar with conical rollers, but the pipes in question are all rather small.

[21:23:21] <tom3p> yesterday i ran lucid 10.04 on new DM150 with M5i20 and G540. ran great.
[21:23:28] <tom3p> previously on old box, it was stumbly, uneven.
[21:23:33] <tom3p> i figure the sound indicated rt problems.
[21:23:34] <tom3p> was the hal_speaker comp meant to do same audible de-bugging?
[21:23:36] <JT-Shop> Sweet!
[21:24:00] <tom3p> JT-Shop, used your suggested 200 200 2000 2000
[21:24:06] <JT-Shop> IDHAC but my guess is for simulating the noise of steppers so you can play a tune
[21:24:43] <tom3p> wel, i bet it shows up real time disturbances too ( daisy daisy give me HICCUP )

[21:28:57] <JT-Shop> I don't see a hal_speaker comp
[21:34:21] <Tom_itx> how to display numbers in axis?
[21:34:35] <Tom_itx> ie spindle speed, tool touch numbers etc
[21:34:46] <JT-Shop> in a pyvcp panel?
[21:35:04] <robin_sz> you almost certainly want to use a computer for that
[21:36:00] <Tom_itx> JT-Shop, near the bottom http://linuxcnc.org/docs/html/hal_pyvcp.html#r1_6
[21:36:34] <Tom_itx> but without the close tabs
[21:36:54] <Tom_itx> #xxxx numbers
[21:39:19] <Tom_itx> or maybe i should ask how to store #xxxx numbers to nets? or what?
[21:40:11] <JT-Shop> number displays http://linuxcnc.org/docs/html/hal_pyvcp.html#r1_6_4
[21:40:20] <JT-Shop> do you have a pyvcp panel now?
[21:40:26] <Tom_itx> do i?
[21:40:31] <Tom_itx> wtf is it?
[21:40:41] <Tom_itx> i'm using stock live cd install
[21:40:42] <Tom_itx> axis
[21:41:00] <JT-Shop> from the step conif wizard?
[21:41:05] <JT-Shop> or a sample config
[21:41:10] <Tom_itx> no i modded my own
[21:41:17] <Tom_itx> from a sample yes
[21:41:18] <JT-Shop> from a sample?
[21:41:20] <JT-Shop> ok
[21:41:57] <JT-Shop> create a file in your config directory myname.xml and name what you like
[21:42:58] -!- skunkworks has quit []
[21:43:01] <JT-Shop> and do you have a postgui.hal file?
[21:43:08] <Tom_itx> i doubt it
[21:43:18] <JT-Shop> you need one of them too
[21:43:19] <Tom_itx> just 2, the standard one and one for my pendant
[21:43:33] <JT-Shop> add a postgui.hal empty file
[21:43:40] <JT-Shop> and the .xml file
[21:44:59] <Tom_itx> all i have is the ini, the hm2-stepper.hal and my_jog.hal
[21:46:31] <Tom_itx> ok, added those 2 files
[21:47:24] <JT-Shop> in your ini file in the [DISPLAY] section add PYVCP = whateveryounamedit.xml
[21:47:55] <JT-Shop> in the [HAL] section add POSTGUI_HALFILE = postgui.hal
[21:48:01] <JT-Shop> if you named it that
[21:48:39] <Tom_itx> done
[21:49:22] <JT-Shop> ok, you need two tags in the xml that wrap all the widgets <pyvcp> and </pyvcp>
[21:49:51] <Tom_itx> done
[21:53:04] <JT-Shop> put this between the two pyvcp tags <led halpin="my-led"/> and run your config
[21:55:41] <Tom_itx> don't see anything different

[22:01:12] <Tom_itx> i added their led example code as well and tried that

[22:02:28] <Tom_itx> not the recent changes

[22:05:49] <Tom_itx> the others are there too
[22:07:23] <JT-Shop> you misspelled PYVCP and you have the postgui in the wrong section
[22:08:02] <Tom_itx> where does postgui go?
[22:08:10] <JT-Shop> POSTGUI_HALFILE = postgui.hal goes after HALFILE = my_jog.hal
[22:09:39] <JT-Shop> the xml looks ok
[22:09:50] <Tom_itx> looks ok but i got errors on it
[22:10:14] <JT-Shop> what error?
[22:10:23] <Tom_itx> remove the =

[22:10:56] <Tom_itx> what goes in the postgui file?
[22:10:59] <JT-Shop> now you have a pyvcp panel?

[22:11:05] <Tom_itx> yes
[22:11:13] <Tom_itx> with a dot
[22:11:27] <JT-Shop> all the net commands that link pyvcp dodads with hal
[22:11:57] <JT-Shop> so if you add a number display to your xml file you have to make the net connection in the postgui.hal file
[22:11:58] <Tom_itx> how do you hook a #xxxx number to hal?
[22:12:05] <Tom_itx> variable
[22:12:08] <JT-Shop> which number?
[22:12:08] <Tom_itx> content
[22:12:19] <Tom_itx> i dunno, i'd have to look
[22:12:27] <Tom_itx> tool touch
[22:12:31] <Tom_itx> would be one
[22:12:48] <Tom_itx> spindle speed would be another but it's in the hal stuff i think already
[22:13:13] <JT-Shop> first create a number display in the xml file
[22:14:12] <Tom_itx> for example, the values collected in the tool-length-probe.ngc example file
[22:14:30] <Tom_itx> #5063
[22:15:03] <JT-Shop> I don't know if that value is in hal but halui has tool offsets for all axis
[22:15:17] <Tom_itx> i'll fiddle with it later
[22:15:22] <JT-Shop> halui.tool.length-offset.x
[22:15:24] <Tom_itx> i smell chicken fryin
[22:15:34] <JT-Shop> yum, be right over
[22:16:38] <Tom_itx> i'd want length-offset.z wouldn't I?
[22:16:59] <Tom_itx> you're spending too much time on the lathe
[22:17:41] <JT-Shop> what ever you want I just grabbed one to show you
[22:17:47] <Tom_itx> i know
[22:19:20] <Tom_itx> can you display the widgets where you want them or how do you move them around?
[22:20:42] <JT-Shop> yea, it is a bit of a pain but using the hbox and vbox you can do most things
[22:21:09] <JT-Shop> they are displayed in the order you have them in the xml file
[22:22:02] <Tom_itx> i figured that

[22:31:27] <Tom_itx> JT-Shop, what type of things get displayed on the left side? is that user configurable as well?
[22:31:33] <Tom_itx> or pre-defined
[22:31:55] <Tom_itx> coolant and spindle are there
[22:35:09] <JT-Shop> that is part of Axis and depending on your config as to what is displayed
[22:40:06] <jdhNC> I ended up just using (debug,) but sometimes, they wouldn't go away, even if you clicked the [x] to close them
[22:40:26] <jdhNC> so I had the last 10 or so values covering up the axis display
[22:40:53] <JT-Shop> :?
[22:41:03] <jdhNC> heh
[22:41:20] <jdhNC> I was trying to display the #5063 from the probe last night

[22:42:51] <JT-Shop> ah
[22:42:54] <jdhNC> I added a line, (debug, Probe saw #5063) that displayed on the bottom right of the axis display
[22:43:22] <jdhNC> with a little red X to get rid of it. The X would click, but the message wouldn't go away and they started stacking up
[22:43:37] <JT-Shop> I think classicladder can see them but not sure

[22:56:53] <Danimal_garage> what happened to it?
[22:57:05] <JT-Shop> too much tannerite
[22:57:19] <Danimal_garage> no clue what that is
[22:57:22] <JT-Shop> blew the side out of a 3/8 wall 8" pipe
[22:57:32] <Danimal_garage> wow!
[22:57:37] <Danimal_garage> impressive
[22:57:39] <JT-Shop> you shoot it with a rifle and it explodes
[22:58:05] <JT-Shop> so we were launching objects into the air Sunday and we found a design flaw

[22:58:15] <Danimal_garage> lol
[22:58:40] <Danimal_garage> so im thinking of grabbing this laser at the surplus yard
[22:58:41] <JT-Shop> first shot put the projectile up about 250-300'
[22:58:52] <Danimal_garage> nice
[22:59:00] <JT-Shop> put on your engraving table?
[22:59:39] <Danimal_garage> ha, well, it's a bit big for that. the unit is like 6 feet long, 55" tall, and 32" deep
[22:59:46] <Danimal_garage> it has a small table inside of it
[23:00:16] <JT-Shop> oh it is a complete cnc laser?
[23:00:37] <Danimal_garage> it's kinda weird, there's a camera, i think you put a drawing in there and it engraves a duplicate on a part
[23:00:45] <Danimal_garage> not exactly cnc
[23:00:51] <Danimal_garage> but yea, complete
[23:01:00] <JT-Shop> oh a duplicator thingy
[23:01:03] <Danimal_garage> almost like a tracer
[23:01:05] <Danimal_garage> yea
[23:01:17] * JT-Shop gets a glass of red and looks for material for rocket fins
[23:01:28] <Danimal_garage> looks like it has a couple steppers on it for xy
[23:01:39] <Danimal_garage> i firgure maybe run it on emc?
[23:01:56] <Danimal_garage> he said the machine doesnt work, but the laser part should be good
[23:02:32] <Danimal_garage> it's so big and heavy though....
[23:03:00] <Danimal_garage> it would have to live outside
[23:03:04] <Danimal_garage> under my patio
[23:04:20] <JT-Shop> I think it is a bit of a challenge to get the laser to fire like you want but doable iirc
[23:04:33] <Danimal_garage> it has a bunch of adjustments and whatnot
[23:04:55] <skunkKandT> there is a raster program on the wiki
[23:05:08] <skunkKandT> just doing vector would be easy
[23:05:14] <Danimal_garage> yea
[23:05:36] <Danimal_garage> there's gain controls, dark and light switches, etc
[23:05:49] <Danimal_garage> all analog it looks like
[23:07:03] <Danimal_garage> i'm wondering if i can just turn it on and off when its supposed to engrave and when the line ends or whatever.
[23:07:24] <JT-Shop> I guess you could use M3/5 for that
[23:07:31] <Danimal_garage> control the steppers with emc, m3/m5 when the line starts and stops

[23:13:38] <Danimal_garage> im looking for a small vmc

[23:27:20] <JT-Shop> dunno
[23:27:54] <JT-Shop> same as plasma I assume for a vector type file
[23:27:59] <andypugh> Previously the problem has been with motion stutter when changing intensity. That _shouldn't_ happen with M67
[23:28:03] <JT-Shop> turn on move turn off
[23:28:40] <JT-Shop> yea, that is with a raster type file right where someone is trying to draw a picture?
