#emc | Logs for 2010-06-09

[00:01:03] <JPM_Mill> Thanks anyways jim
[00:01:31] <jlmjvm> no prob,wish i could have helped
[00:01:41] <JPM_Mill> lol me too
[00:02:05] <JPM_Mill> any idea on my servo run away issue?
[00:02:49] <jlmjvm> unfortunately im a stepper dude
[00:03:29] <JPM_Mill> no prob thanks
[00:03:48] <jlmjvm> hopefully will have servo motors one day
[00:04:55] <jlmjvm> start it in terminal,go to calibration and see if you get an error,then post that
[00:05:14] <JPM_Mill> how do i do that?
[00:06:05] <jlmjvm> open terminal,type emc,select your config
[00:06:08] <JPM_Mill> nevermind
[00:06:44] <JPM_Mill> http://pastebin.ca/1879391
[00:12:16] <JT-Hardinge> JPM_Mill: when you move in a positive x does the dro change?
[00:14:27] <JPM_Mill> JT: Yes the axis works fine in jog and mpg i only see this behaviour when in mdi
[00:19:00] <JT-Hardinge> all other axes work fine?
[00:20:42] <JPM_Mill> just working on my x axis for now. Waiting on other servos to show up
[00:21:55] <JPM_Mill> drive is AB ultra 100 motor is reliance ac servo 5000 rpm 2000 line encoder
[00:21:57] <Valen> JPM_Mill: you use the sample config or roll your own?
[00:22:17] <JPM_Mill> i modified the sample config
[00:22:44] <Valen> are you sure its a runaway not just a going quickly or something? how are you interfacing with the servo drive
[00:23:01] <JPM_Mill> i also have a heidenhain dro to double check scaling and such
[00:23:52] <JPM_Mill> its a run away i asked it to move 2" and it fell short by .5" and emc gave me a position error
[00:24:03] <Valen> thats not runaway
[00:24:08] <Valen> that sounds like tuning
[00:24:18] <JT-Hardinge> or you have an offset in effect
[00:24:22] <Valen> runaway is you tell it to move .1 and it rockets for the end of the table
[00:24:31] <JT-Hardinge> or out the door
[00:24:34] <Valen> is it a following error?
[00:25:02] <JT-Hardinge> reading back that sounds like your not tuned up yet
[00:25:14] <Valen> that would be my guess
[00:25:16] <JPM_Mill> ok why is it only in one direction
[00:25:20] <JT-Hardinge> increase the f-error try again
[00:25:37] <JT-Hardinge> imbalance somewhere in your drive maybe
[00:25:41] <JPM_Mill> and why not in jog or mpg
[00:25:41] <Valen> you might have some bias or something
[00:25:47] <Valen> they are normally slower
[00:25:53] <Valen> a G0 is as fast as it can go
[00:25:55] <JPM_Mill> i have .2 ferror allready
[00:26:01] <JPM_Mill> g01
[00:26:05] <JPM_Mill> not g0
[00:26:11] <Valen> have you tuned the servo peramiters?
[00:27:45] <JPM_Mill> if the table is at x0 the g01 x-2 works fine but g01 x2 i get a following error
[00:28:42] <JPM_Mill> and f=20
[00:28:44] <JT-Hardinge> have you used HalScope to know that it "works fine"
[00:28:54] <Valen> sorry killed mah client
[00:28:58] <Valen> what did i miss?
[00:29:18] <JT-Hardinge> Sweedish nude skydiving team just landed Valen
[00:29:25] <JT-Hardinge> sorry you missed it
[00:29:30] <Valen> aww shoot
[00:29:36] <JT-Hardinge> :)
[00:29:45] <Valen> the all girls under 18's team too i presume
[00:29:53] <JPM_Mill> JT i will try to plot it
[00:30:15] <JT-Hardinge> JPM_Mill: either your drive is off or you have a mechanical issue in the X positive
[00:30:25] <Valen> the tuning parameters for all our axis are wildy different
[00:30:32] <JT-Hardinge> Valen: they just made 18 I think
[00:30:52] <Valen> P id 4.5 on X, and .8 on z for us
[00:31:11] <Valen> JT-Hardinge: oh well, no great loss then ;-P
[00:31:31] <andypugh> Well, if it makes you feel any better, my modified motor alignment sequence is utterly useless, so my machine only runs one direction too.
[00:31:32] <JT-Hardinge> JPM_Mill: I set a velocity trigger then jogged and watched the trace for error
[00:31:38] <andypugh> Time to sleep.
[00:31:44] <JT-Hardinge> good night andy
[00:33:28] <JPM_Mill> http://imagebin.ca/view/rAjhMVs.html
[00:33:55] <Valen> wow textbook
[00:34:29] <JPM_Mill> now i will do it for the other direction
[00:36:09] <JPM_Mill> http://imagebin.ca/view/PThElc.html
[00:38:16] <JT-Hardinge> I don't see anything wrong with that... and I'm way far from a guesspert on tuning.
[00:38:22] <JT-Hardinge> was that at F20?
[00:38:34] <JPM_Mill> yes both were
[00:39:55] <JPM_Mill> http://pastebin.ca/1879449 here is my ini file
[00:40:01] <JT-Hardinge> did you run over the troubled spot at X1.5?
[00:40:59] <JT-Hardinge> PGAIN=1500 IGAIN=8000 WOW!
[00:41:02] <JPM_Mill> yeah it does not matter where i do it on the table its more direction based than anything
[00:41:44] <JPM_Mill> oh dont look at pgain igain or dgain leftovers from an older config
[00:41:57] <JPM_Mill> look at p, i and d
[00:42:24] <JT-Hardinge> here is my hardinge ini http://www.pastebin.ca/1879450
[00:44:30] <JPM_Mill> Thanks much of my setup is based off of yours you gave it to me a while ago
[00:44:48] <JT-Hardinge> I started with all at 0 except P at 1 then increased it till I got some shaking then increase the I a bit to stop it
[00:45:10] <JT-Hardinge> but do a trace each time to see how each change affects the outcome
[00:45:22] <JT-Hardinge> I forget so easy :/
[00:46:05] <JT-Hardinge> all the while increasing the speed as I tweeked the rest
[00:46:16] <JPM_Mill> I will i just dont get why its good one way almost too good and the other it's f'ed
[00:46:44] <JT-Hardinge> that sounds like mechanical or the drive to me
[00:47:08] <JT-Hardinge> dinner time here! got to go in or I lose out :)
[00:47:33] <JPM_Mill> Thanks for your help. later
[00:47:41] <JT-Hardinge> ok
[00:48:16] <JPM_Mill> Valen any thoughts
[00:49:47] <Valen> how are you interfacing between EMC and the servo drive?
[00:50:24] <Valen> increase minferror some and see if you can keep it running for a while
[00:51:01] <Valen> your P is a factor of 10 higher than ours
[00:51:05] <Valen> dunno if that matters
[00:51:33] <Valen> take FF1 down to 0 for the time being
[00:52:55] <JPM_Mill> what about backlash could that cause some of this?
[00:56:18] <JPM_Mill> http://imagebin.ca/view/QRNTSg9.html
[00:56:33] <JPM_Mill> here is a better plot of the issue
[00:57:53] <Valen> yeah could do
[00:58:03] <JPM_Mill> http://imagebin.ca/view/Irp1SmTv.html
[00:58:10] <JPM_Mill> better plot
[00:58:24] <Valen> actually test it thusly, move it in one direction, move it again in the same direction, then move it in the oposite direction
[00:59:09] <Valen> increase the minferror so you dont get following errors while playing with it
[00:59:50] <Valen> what you might see is the motor accelerating while moving through the backlash, then when it hits the load it gets slowed down
[01:02:16] <JPM_Mill> ah ha its a torque issue
[01:02:29] <JPM_Mill> damm leadscrews
[01:03:28] <Valen> eww
[01:03:44] <Valen> that linearmotionbearings2008 has ballscrew hardware really cheap
[01:03:57] <JPM_Mill> when i increased the feed error the drive triped out on overcurrent and dam near shot the table out the door
[01:04:08] <JPM_Mill> i have ball screws on order
[01:04:23] <JPM_Mill> thanks for the help
[01:04:46] <JPM_Mill> still cant get the calibration screen to pop up though
[01:08:26] <fenn> http://designfiles.org/~bryan/images/toolstache.jpg
[01:08:39] <fenn> dave rauchwerk in austin
[01:11:09] <cradek> fenn: what is it?
[01:19:36] <JPM_Mill> Cradek: could you help me with my calibration issue?
[01:54:43] <pfred1> cradek hey i got image-to-gcode to run on my emc machine
[02:18:36] <Valen> JPM_Mill: sure its not poping up behind axis or something?
[02:20:27] <skunkworks> question... Is the only way to set the internal estop button is through the halui - 2022halui.estop.activate
[02:23:19] <skunkworks> * I would like it so when the external 'physical' estop button is pressed - the internal emc one stays pushed even when the external estop is let out.
[02:26:04] <skunkworks> * skunkworks is off to look at some of the sample configs.
[02:31:43] <morfic> i don't think i started a thread on the ML before, did my G71 one make it?
[03:07:55] <cradek> yes but it probably should have been on the devel list
[03:10:11] <cradek> on users, you may get a lot of useless "it ought to work like ___ [other machine]" without any real understanding of the issues
[03:10:42] <pfred1> is it safe to run DRI on emc?
[03:11:41] <cradek> for one thing it's tempting to think of implementing it with O words demarcating the motion (like maybe an O-sub)
[03:12:02] <cradek> none of the rest of emc's gcode uses N words in the way the haas example does
[03:18:11] <morfic> haas/fanuc
[03:18:49] <morfic> i have no problem with that either
[03:19:35] <cradek> I wonder what's easier (possible) to implement
[03:20:08] <morfic> any problem if i repost this to the devel list? i did want some user input, since i don't know all controls, maybe there is something cool someone brings up, aside from the "industry standard G71 does such and such" i see no standard, i see a "what we are used to in our shop"
[03:21:21] <morfic> cradek: getting geometry from a o word sub sounds good actually, but would need more gcode conversion on our part :) aside from the post processor adjustment and worse, the VeriCut adjustment
[03:21:30] <morfic> but i deal with that when i have a working G71
[03:21:43] <Valen> pfred1: DRI meaning?
[03:22:02] <pfred1> Valen Direct Rendering Interface its hardware video acceleration
[03:22:20] <Valen> just wanted to be sure, we did that with our xeon system
[03:22:24] <Valen> nvidia binary drivers
[03:22:30] <Valen> it was SMP though
[03:22:37] <morfic> line/line segments i see no problem with right now, still a little wobly on arc/line intersections, hoping to find a library to peruse, since it's a common thing i would think
[03:22:44] <cradek> nvidia binary drivers just screw stuff up IMO
[03:22:58] <pfred1> Valen nvidia does it differently
[03:23:03] <cradek> and good luck getting rid of them once you try them, sadly
[03:23:26] <Valen> cradek, worked fine for us
[03:23:37] <pfred1> I should just get a nvidia card for that machine
[03:23:52] <Valen> you can remove them with the uninstall thing in the installer, that seems to work
[03:23:56] <pfred1> it'd be easier than setting up the antique ati card i have in it now
[03:24:04] <cradek> I have never seen the nvidia driver not badly screw up latency
[03:24:10] <morfic> binary blobs often do not behave, so my plan is on a radeon card where i can use linux kernel DRM/DRI only
[03:24:12] <cradek> as my momma said - don't come crying to me
[03:24:20] <Valen> cradek on that xeon system we had 2000 latency
[03:24:36] <pfred1> cradek software GL is faster than hardware acceleration?
[03:24:44] <morfic> binary drivers keep you behind if they can't be compiled against a newer kernel until they catch up
[03:24:47] <cradek> software gl doesn't screw up latency
[03:25:14] <morfic> cradek: so repost to emc-devel == a'ok?
[03:25:24] <pfred1> just seems sort of backwards to me that having hardware and not using it is better than using hardware you have
[03:25:47] <Valen> the problem is the binary driver may not play nice with latency
[03:25:55] <cradek> morfic: I guess I have no opinion about whether you should repost it right away. I think you've got my input already from our previous conversations...
[03:26:28] <cradek> I think it's safe to assume that all -devel readers also read -users
[03:26:47] <cradek> so the only reason to post to -devel instead of -users is to avoid unwanted noise
[03:27:17] <cradek> (fortunately it's finally calmed down a bit lately)
[03:28:27] <pfred1> my emc machine locked up yesterday running the regular ati driver
[03:31:02] <cradek> I think I usually end up running the vesa driver on whatever old video card
[03:33:42] <pfred1> I may have to upgrade
[03:53:03] <pcw_home> pfred1: How goes your step driver project?
[03:53:24] <pfred1> pcw_home done
[03:53:40] <pfred1> I'm working on the machine now
[03:54:05] <pcw_home> Have you tried dual motors yet?
[03:54:36] <pfred1> no not yet
[03:54:50] <pfred1> well wait I did a while back ran two drivers
[03:55:53] <pfred1> but not in a machine just on my workbench
[03:56:00] <pcw_home> I'm curious to see how it behaves
[03:56:24] <pfred1> they'll be on different lead screws
[03:57:49] <pcw_home> Ah. I thought you had some idea a driving a single leadscrew at both ends...
[03:58:13] <pfred1> well I thought about it but I'm not doing that with this machine
[03:58:49] <pcw_home> Would be a pain wiring wise
[03:58:53] <pfred1> I need to turn down the end of my leads so I can connect them to my motors
[03:58:58] <pfred1> how you figure?
[04:00:02] <pcw_home> well if one axis has to move then you have 2 cables at both ends to guide/protect
[04:00:37] <pfred1> I htink I'm going to go with the draped wire effect
[04:01:02] <pcw_home> I mean a cable at each end
[04:01:04] <pcw_home> Yep seen a lot of the draped wire system...
[04:01:16] <pfred1> seems simplest
[04:01:52] <pfred1> I'll have to drape Y and Z X will be stationary
[04:03:55] <pfred1> I have to see tomorrow if my rig up will work to turn down my lead screws
[04:04:57] <pfred1> I'm going to run hose motor couplers
[04:09:05] <pcw_home> What kind of leadscrews?
[04:09:20] <pfred1> 1/2-10 acme
[04:10:12] <pfred1> but my stepper motor shafts are 1/4" so I need to turn an end down some so I can get a hose to fit on both
[04:10:43] <pfred1> I figure i can grind an end while it spins
[04:10:58] <pfred1> I'll see tomorrow how well that works
[04:11:27] <pcw_home> This is a retrofit?
[04:11:47] <pfred1> no I'm scratch building a router gantry
[04:12:27] <pcw_home> So what kind of nuts you us use on the leadscrew?
[04:12:59] <pfred1> I'll make fiber or HDPE haven't decided yet I'll make each see whic hI prefer
[04:47:51] <morfic> cradek: then i just sit tight and next time i find myself with spare time start diving into the interpreter with some more schmackes ;)
[04:51:27] <Endeavour> Hello pfred1
[04:51:43] <pfred1> Endeavour hi
[04:52:00] <Endeavour> I ended up getting a Fireball CNC
[04:52:10] <cradek> morfic: that way lies madness, you know...
[04:52:11] <pfred1> nice
[04:52:12] <Endeavour> Don't know if I mentioned it to you.
[04:52:20] <Endeavour> I'm also in the process of acquiring a Gecko.
[04:52:27] <Endeavour> It'll be a while yet; funds are scarce.
[04:53:03] <pfred1> someone elsein here has a fireball they say their table warps
[04:53:53] <pfred1> well dips or bows in the middle
[08:32:33] <mk0> is it possible to set NiCr string temperature while cutting in emc2? i mean to set what voltage should be applied on string.
[08:32:37] <mk0> to string
[08:39:27] <alex_joni> mk0: not without doing some work
[08:39:41] <mk0> what work?
[08:39:55] <alex_joni> I imagine you could set spindle speed from the g-code, and do some HAL scaling on that to control your current, which results in the needed temperature
[08:40:46] <mk0> oh, no, not so "right", without feedback, just with keyboard.
[08:44:15] <alex_joni> mk0: it depends how you plan to control the voltage
[08:50:12] <KimK> cradek: I tried installing EMC2 on 10.04 as you told me. It seemed to install, and the /etc/security/limits.conf file even had a commented out line similar to your wiki line. But I haven't been able to get it to start using either line. Toolchange window comes up, then crash. Using your wiki line "* - memlock 20480" gives me these errors http://www.pastebin.ca/1879572 . And using the included line "* hard memlock 20480 #EMC2" gives me these errors http
[08:50:12] <KimK> ://www.pastebin.ca/1879575 . Any advice? Thanks in advance.
[08:51:35] <KimK> cradek: Oops, flooding again, that last link should be http://www.pastebin.ca/1879575 . Thanks again.
[08:52:20] <alex_joni> KimK: the first attempt is good ;)
[08:52:28] <alex_joni> "* - memlock 20480"
[08:52:47] <alex_joni> the error you're getting (albeit also memory related) is because of an old emc.nml
[08:53:24] <alex_joni> e.g. using a 2.3.x config on 2.4.x
[08:53:42] <KimK> Oh, OK, I didn't think of that, I thought that was handled in the new packages. I'll go try again. BRB.
[08:53:58] <alex_joni> KimK: so put the initial line in, reboot
[08:54:08] <alex_joni> then try emc2 with a copy of a sample config, it should work
[08:54:19] <alex_joni> then you can take over your config, and comment out the NML_FILE line
[08:55:54] <KimK> This was a sample config (AXIS_9-axis), but I never went in an blocked the nml line, I never thought of that, I'll go try all this. Thanks!
[08:59:45] <alex_joni> KimK: Machine configuration directory is '/home/kkirwan/emc2/configs/sim'
[08:59:56] <alex_joni> maybe it's a config that's left over from 2.3.x
[09:00:26] <alex_joni> btw, you should install emc2-2.4.1 not 2.4.0
[09:00:48] <alex_joni> but I see it's not compiled for 10.04 yet, so disregard that :)
[09:03:44] <KimK> Yes, I was going to ask about Synaptic and EMC2 repositories for 10.04, etc., but I thought better of it. All in due time, I guess. I'll be right back.
[09:42:37] <alex_joni> KimK: better?
[09:44:54] <KimK> alex_joni: Thanks, that (those?) fixed it. I'll look forward to the creation of 10.04 repositories, etc. If it seemed to take quite a while, it was because I decided (while rebooting anyway) to boot my 8.04 partition, which hasn't seen much use lately, and check for updates. Yes, about 150 Megs worth. Thanks again for your help.
[09:52:08] <KimK> alex_joni: Well, OK, almost working. Latency test does not seem to start, at least not from the main menu. Stepconf wizard does start.
[09:54:17] <KimK> Ha, my fault, I left EMC/AXIS running and forgot about it. Latency works fine.
[09:55:04] <KimK> Thanks again, back later.
[09:55:28] <Valen> there any noticable differences between 10.04 and 8.04 EMC wise?
[10:08:30] <alex_joni> Valen: no
[10:08:38] <alex_joni> only that 10.04 isn't quite as tested
[10:08:50] <Valen> 10 second boot vs 40 might be nice ;->
[10:08:58] <alex_joni> and that there isn't a repository for emc2 yet
[10:08:59] <alex_joni> etc
[10:09:04] <alex_joni> it'll get there, patience :D
[10:09:08] <Valen> no latency changes or anything?
[10:09:20] <alex_joni> well, the 10.04 kernel is SMP by default now
[10:09:31] <Valen> thats handy
[10:09:33] <alex_joni> and it seems that on SMP systems that improves latency a bit
[10:09:44] <alex_joni> but I haven't booted it myself yet :)
[10:09:45] <Valen> halved or better on my 2
[10:09:51] <alex_joni> so.. it's only hearsay your honour
[10:10:11] <Valen> on my xeon it went from ~10k to 2k, and the atom from ~8k to 4k
[10:19:10] <Valen> the xeon is using the binary nvidia driver to boot, lots of powah graphics wise there
[10:33:25] <Endeavour> Hello.
[11:20:53] <morficmobile> hey Endeavour
[11:47:05] <alex_joni> EDM anyone? https://www.surplex.com/de/maschinen/ansicht,7,gf-system-3r-junior-grosser-posten-erodierzubehoer-91947.html?auction_id=123&lotnr=20
[13:13:14] <pcw_home> Is that just the tools (bits? )
[13:40:18] <alex_joni> pcw_home: yeah
[13:42:29] <pcw_home> Lots of 'em
[13:55:15] <i_tarzan> punch dies?
[13:56:58] <morficmobile> electrodes if for edm i guess
[14:01:03] <Valen> sure is alot of whosits
[14:05:28] <morficmobile> i saw a few whatnots
[14:17:06] <JT-Work> a few spapoops in there too I think... kinda hard to see the detail
[14:34:39] <JT-Work> well this is interesting... when I enable the amps on my mill the X and Y move at a speed much faster than rapid about 1" then I get a following error...
[14:35:23] <frallzor> * frallzor wishes he had a usb-dvdrom now
[14:38:09] <JT-Work> hmm, the dro part works on all three axis
[14:41:17] <frallzor> hmm why this odd boot error
[14:45:06] <frallzor> anyone with a nice guide on how to make the live-cd boot from usb? :P
[14:45:29] <cradek> no, but the internet knows how
[14:45:43] <cradek> there's nothing special about our cd - you can use the ubuntu instructions
[14:45:47] <cradek> check the ubuntu forums
[14:45:59] <frallzor> then I might have a crappy memory or something
[14:46:01] <frallzor> ill try another
[15:14:28] <frallzor> halfway there, but the bloody creator just made a plain live-cd with no install option :P
[15:15:54] <frallzor> but there is a nice install icon on the desktop, so hey might work
[15:21:11] <frallzor> well this seems to turn out fine =D
[15:48:56] <morficmobile> frallzor: sounds like 10.4
[15:56:13] <frallzor> nope 8.04
[15:56:54] <frallzor> now its just to config emc and the touchscreen
[15:59:40] <elmo40> anyone try these guys? http://www.tools4cheap.net/
[16:05:54] <frallzor> which buttons = = on us layout?
[16:06:18] <elmo40> next to 'backspace'
[16:06:23] <elmo40> the +
[16:06:50] <frallzor> ahh ty
[16:06:59] <elmo40> top row: `1234567890-=
[16:07:30] <frallzor> ah bloody computer works like a charm
[16:07:51] <elmo40> horrible feeling isn't it ;)
[16:07:55] <frallzor> yup
[16:08:05] <frallzor> now I just need to setup the screen
[16:42:45] <frallzor> 13500ns is the best latency I can get atm, glxgears, moving windows around, opening FF etc etc
[16:43:05] <frallzor> decent
[16:48:07] <bricofoy> I got near the same on my P4 box
[16:49:14] <archivist> frallzor, I found a new way to upset latency on a box, edit a file and use the scroll wheel on the mouse to scroll the file
[16:50:34] <frallzor> anyon into linux and want to help a poor little man getting his touchscreen working? :)
[17:01:57] <archivist> frallzor, after I get mine going I will
[17:02:57] <elmo40> frallzor: specs?
[17:03:24] <frallzor> bloody LG monitor
[17:03:36] <frallzor> takes more than my knowledge to get it going =)
[17:03:38] <elmo40> may be old... http://www.linuxjunkies.org/html/XFree86-Touch-Screen-HOWTO.html
[17:03:46] <frallzor> but it will be working
[17:04:02] <frallzor> it works but need evtouch or some driver like that
[17:04:09] <frallzor> x and y flipped and boxy movement
[17:04:30] <elmo40> LG doesn't make the touch part... someone else does.
[17:04:35] <elmo40> http://www.conan.de/touchscreen/evtouch.html
[17:04:55] <frallzor> ive been through this before, I cant fix it =)
[17:07:42] <frallzor> but it seems simple enough for someone into ubuntu
[17:09:54] <frallzor> but the link you posted last should be the solution
[17:10:03] <frallzor> not to just get the evtouch driver
[17:15:15] <Jymmm> If you had one of these, would you pay $152 to get an extra 3yr onsite warranty http://www-307.ibm.com/pc/support/site.wss/quickPath.do?quickPathEntry=87445BU If it doesn't take you straight to the correct page, click on the lenovo link, then paste the url again (I think it needs a cookie)
[17:15:47] <frallzor> if its as good as the one ive experienced with my dell. yes
[17:16:11] <Jymmm> Did you look at the machine?
[17:16:11] <frallzor> help the day after the call
[17:16:32] <Jymmm> specs.
[17:16:43] <frallzor> cant see a machine at all there
[17:16:56] <frallzor> but Id take the warranty if the machine is important to you
[17:17:02] <Jymmm> follow the instructions I gave =)
[17:17:26] <frallzor> ah
[17:17:32] <frallzor> a thinkpad
[17:17:59] <Jymmm> Then click on PRODUCT INFORMATION, then on OVERVIEW
[17:18:44] <Jymmm> T7200(2GHz), 1GB RAM, 120GB 5400rpm HD, 15.4in 1680x1050 LCD, 128MB ATI Radeon X1400, CDRW/DVDRW, 802.11n wireless, Bluetooth/Modem, 1Gb Ethernet, UltraNav, Secure chip, Fingerprint reader, 6c Li-Ion batt, WinXP Pro
[17:19:09] <frallzor> well if its important and if it breaks you need it fast, sure the warranty is nice to have
[17:19:17] <Jymmm> It now has 4GB ram and 350GB hdd,
[17:19:45] <Jymmm> That's not the point, it's a matter of where to invest the money. In a warranty, or towards a new machine.
[17:20:01] <Jymmm> That's why I gave the spec link.
[17:20:15] <frallzor> ah
[17:20:26] <frallzor> you you wanted to ask if it was worth warranty
[17:20:30] <Jymmm> $152 in a P3 wouldn't be a good investment no matter what, as example.
[17:20:33] <frallzor> for a new one
[17:20:42] <frallzor> get a new one then =)
[17:22:58] <JT-Work> at least the Anilam has encoder feedback and the drives look like they might take a velocity input...
[17:23:54] <frallzor> to know the distance / rew for a pinion, is it pi * the number of teeth?
[17:29:22] <morficmobile> haven't used my 10.4 VM in a while, 153 packages to update already, weee
[17:34:30] <morficmobile> hey andypugh
[17:34:39] <andypugh> Hi chaps
[17:46:40] <isssy> net.com
[17:49:38] <JT-Work> hmm, my Anilam has a dead battery on the multi function board... I think I'll change it
[18:01:46] <JT-Work> instead of converting it to EMC
[18:08:11] <Jymmm> BRAND NEW BP http://sfbay.craigslist.org/sby/tls/1783075733.html
[18:09:26] <JT-Work> new battery for my BP $6 delivered to my door
[18:10:17] <Jymmm> Battery? BP? Blood Pressure ?
[18:11:07] <JT-Work> BP series 1 with Anilam CNC control on it .... PAY ATTENTION JYMMMMMMMM!
[18:11:17] <JT-Work> :P
[18:12:29] <Jymmm> Battery?
[18:13:27] <cradek> JT-Work: the GE550 control I took off the hnc had a bank of D cell nicads and what looked like a car battery charger to charge them
[18:13:49] <Jymmm> cradek: that's bizzare imo
[18:13:57] <frallzor> what is the short command for entering terminal? just in case I mess up when trying to get touch working? =)
[18:14:13] <cradek> JT-Work: also, it had a whiteboard-type area on the front panel to write the numbers with a pen, so you can put them back in when it forgets
[18:14:23] <Jymmm> LOL
[18:14:29] <cradek> ... using the thumbwheels
[18:14:31] <Jymmm> Well, wasn't that nice of them
[18:14:36] <cradek> yeah, very pragmatic
[18:15:50] <Jymmm> Hmmmm, I don't NEED one, but... http://sfbay.craigslist.org/sby/tls/1782693652.html
[18:16:02] <Jymmm> Is that one of those china specials?
[18:18:34] <cradek> you can get a new china special for that $40
[18:21:12] <WalterN> there are very few things that I've actually used one of those with
[18:22:42] <cradek> I use mine occasionally. I wish it were a little bigger. 12x18 is a common size because they're around 80lb and therefore easy to carry around and easy to ship.
[18:25:04] <WalterN> cradek, what do you use it for?
[18:25:38] <cradek> mostly, marking and measuring with a height gauge
[18:25:56] <WalterN> marking?
[18:26:10] <WalterN> oh
[18:26:12] <WalterN> like
[18:26:40] <WalterN> taking a flat suface, and seeing where the high points are?
[18:27:12] <cradek> yes sometimes that - but more often, just marking layout lines
[18:27:40] <cradek> I don't do it too much because I have cnc though.
[18:27:47] <WalterN> what? how would one of those be useful for layout lines?
[18:28:37] <cradek> http://www.ehow.com/how_5207111_use-height-gauge.html
[18:29:44] <cradek> http://www.mini-lathe.com/Mini_mill/Accessories/Layout/height_gage.jpg
[18:30:05] <cradek> http://www.finelinehair.com/home/height_gage_scribe.jpg
[18:30:35] <WalterN> I just use my dial calapers and get close for layouts... to doube check against the DRO.. make sure I'm not off by .1" or more or something stupid like that
[18:32:32] <cradek> yes that can get you close, but a flat base is important if you need to measure or mark an actual height perpendicular to it
[18:34:24] <WalterN> hmm, most of the stuff I've made can start with a nice square piece
[18:34:30] <JT-Work> cradek: the Anilam support guy asked me if I had the disk from the machine builder... I said no, he said ok, when you get the battery installed call me back and we will play 20 questions
[18:34:56] <WalterN> never really did anything with castings type things... which I presure would be more useful for
[18:35:46] <JT-Work> I have an army issue cast iron surface plate about 12x18
[18:36:39] <JT-Work> * JT-Work wanders over to do some manual milling on the cnc mill :/
[18:51:21] <i_tarzan> i never use those gages
[18:51:31] <i_tarzan> too expensive for marking
[19:10:00] <ries_> ries_ is now known as ries
[21:38:27] <frallzor> bah I hate ubuntu 8.04 =(
[21:38:39] <frallzor> it just wont stop using the default driver for the touch
[21:39:06] <frallzor> any tips?
[21:54:26] <andypugh> Considering that I thought that Dean Smith and Grace looked to be about to close for good when I visited 10 years ago, they do appear to be still going. And their latest machine is a monster: http://www.deansmithandgrace.co.uk/icms_assets/files/Travelling_Gantry_Machine.pdf
[22:36:25] <morfic> <cradek> mostly, marking and measuring with a height gauge <WalterN> what? how would one of those be useful for layout lines? <--- interesting when you realize how natural some stuff comes, that's still a special occasion for others
[22:36:58] <frallzor> how hard and time consuming is it to install emc2 from scratch?
[22:40:37] <celeron55> building it?
[22:40:59] <celeron55> and building an rtai-enabled kernel?
[22:41:03] <frallzor> yup
[22:43:10] <celeron55> i guess not really time consuming if you don't run into strange problems - i think the general procedure is documented somewhere
[22:50:48] <WalterN> morfic: special occasion for who?
[22:52:43] <morfic> frallzor: a couple minutes from source once you have all deps
[22:53:21] <morfic> WalterN: those who wonder how you would use a surface plate in the process of marking and measuring parts
[22:54:13] <WalterN> oh, measuring parts I do it all the time
[22:54:30] <WalterN> or rater, a nice solid hard flat surface
[22:54:52] <WalterN> just... never for making layout lines
[22:55:10] <andypugh> Most height gauges I have seen have had a carbide tip specifically for marking-out work.
[22:55:57] <WalterN> anyway, gotta run back to the shop, TTFN
[22:56:17] <andypugh> Set the gauge, plonk the work on the table, slide the height gauge past it, and there you have a line
[22:56:41] <eric_unterhausen> eric_unterhausen is now known as EricKeller
[22:56:57] <andypugh> frallzor: About 8 hours, including all the downloads and kernel-building.
[22:58:11] <EricKeller> OT: I know someone who is participating in RAAM, bike race from Cali to Maryland
[22:59:16] <EricKeller> the leading woman has been averaging over 15mph for 26 hours
[22:59:45] <frallzor> andypugh ouch
[23:00:06] <frallzor> guess ill wait and see if my monitor will work first =)
[23:00:24] <andypugh> Might be quicker if you a) know what you are doing and b) have a fast computer.
[23:00:41] <frallzor> I have no idea what im doing =)
[23:00:52] <frallzor> cant even get my touchscreen working on my own :)
[23:01:48] <EricKeller> kernel building can take a while. I had some slow computers that required a custom kernel for any kind of performance -- easily took 8 hours just for the build
[23:02:21] <andypugh> I struggled for weeks, until somebody here made this set of instructions, that just worked. http://neo-technical.wikispaces.com/emc2-ubuntu
[23:03:00] <Valen> if your going to roll a kernel on a slow computer, look at distcc
[23:03:12] <Valen> lets you get multiple computers in on the compiling action
[23:03:37] <EricKeller> that sounds interesting, but they were on robots so the networking was a pain
[23:05:16] <frallzor> anyone tried these? http://www.linuxcnc.org/mozmck/
[23:06:00] <frallzor> seems pretty nice if it works without hickups for a stable system
[23:07:56] <andypugh> Is it SMP?
[23:08:22] <frallzor> SMP?
[23:08:49] <andypugh> http://en.wikipedia.org/wiki/Symmetric_multiprocessing
[23:08:53] <frallzor> they are packages at least
[23:10:22] <frallzor> too confused, bed, NN
[23:11:44] <Valen> the 10.04 stuff is
[23:11:52] <Valen> dont know about that one though
[23:41:50] <Jymmm> This looks like a great deal http://sfbay.craigslist.org/sby/tls/1783942625.html
[23:42:04] <Jymmm> $2100 obo for a BP + tooling
[23:43:48] <Jymmm> wish I had a place for it and 220V@60A circuit =(
[23:45:20] <morfic> andypugh: 8 hours? o_O
[23:45:48] <andypugh> Custom kernel from scratch, including downloading the dependencies, about that, yes.
[23:59:03] <Valen> 60A 200v is a lot of A
[23:59:52] <Jymmm> I think clothes dryer is 40A
