[00:02:02] <andypugh> Room for this? http://cgi.ebay.co.uk/Ravensburg-P20-III-CNC-Modular-Floor-Lathe-/270607284211
[00:02:10] <andypugh> (Though it is quite expensive)
[00:03:16] <JT-Shop> perhaps, but I don't think it will fit through the door even though it is quite large

[00:04:32] <andypugh> Any lathe that size is going to have the work on it 3-shifts for days isn't it?
[00:05:11] <JT-Shop> it appears the tool slide can move quite a bit in the X
[00:05:30] <JT-Shop> building ships perhaps
[00:06:08] <andypugh> Yes, but if you put something faceplate-diamter on, it would foul the bed.
[00:06:41] <andypugh> In fact, I have a feeling you can move the whole bed backwards too. (hence "Modular")
[00:07:44] -!- skunkworks_ has quit [Ping timeout: 246 seconds]
[00:08:29] <JT-Shop> and the long cables support that...
[00:08:54] <JT-Shop> at least I have no desire to purchase it from flea bay

[00:18:56] <JT-Shop> that is too much
[00:19:32] <atom1> http://tom-itx.dyndns.org:81/~webpage/intel_atom/sherline4.jpg
[00:19:36] <atom1> my humble setup
[00:19:47] <atom1> oh with new steppers
[00:20:09] <Connor> You build the enclosure?
[00:20:25] <atom1> yeah
[00:21:06] <atom1> hopefully one of these days this pc will be out there with emc on it
[00:21:26] <Connor> My enclosure started out as a Dot Matrix printer cabinet. I ended up using the Plexi from it, and the general angle, but, built it about 6" taller out of MDF
[00:21:40] <Connor> http://www.ivdc.com/cnc
[00:21:48] <JT-Shop> atom1: nice enclosure around your mill
[00:22:17] <Connor> I'm wishing I had mounted my CNC on it's own base, instead of using the base of the cabnet
[00:22:30] <atom1> i made it so i could play with the sherline in the basement
[00:22:36] <Connor> but, it's all integrated, so, I guess it doesn't make much diff.
[00:22:38] <atom1> but it got crouded so it's out there now
[00:23:21] <atom1> it's certainly not a Mori Seki
[00:23:35] <Connor> a what?
[00:23:50] <atom1> google
[00:24:00] <atom1> it's the cadillac of cnc
[00:24:08] <atom1> well one of em anyway
[00:24:11] <pcw_home> andypugh: I think addressing on BSPI/DBSPI limits the firmware to 4 BSPI/DBSPI modules per card
[00:25:01] <andypugh> OK, I will change that then, I had assumed 16 :-)
[00:25:49] <andypugh> Dean Smith and Grace would be the JCB of CNC I think :-)

[03:17:26] <geo01005> Hey Guys, is there a problem with emc and Ubuntu version 10.04.2 ? ever since I upgraded rtai won't work.
[03:24:51] <L84Supper> rtai has to be compiled for the kernel, if you change kernels you have to change RTAI
[03:26:00] <geo01005> So I thought that the kernel would not change from 10.04 to 10.04.2, am I wrong?
[03:26:55] <L84Supper> I don't keep track of Ubuntu anymore. Did the upgrade change the kernel?
[03:27:39] <geo01005> I'm not sure how to check.
[03:27:55] <L84Supper> it probably did
[03:28:08] <geo01005> I just reinstalled and the upgrade was automatically done.
[03:29:22] <L84Supper> another good reason to turn off auto updates in Ubuntu
[03:29:51] <geo01005> Yeah, that has killed my machine twice now.
[03:30:25] <L84Supper> reinstall, leave the network cable unplugged, turn off auto updates
[03:31:14] <L84Supper> I haven't installed Ubuntu in a while, does it automatically update or does it ask you first?
[03:32:06] <L84Supper> how long does the install take? 20 minutes?
[03:32:28] <geo01005> On this old machine about 2 hours.
[03:32:41] <geo01005> It askes, but I didn't look to see what every update was.
[03:32:59] <geo01005> I suppose I'll try to remove the network cable after installing.
[03:33:01] <L84Supper> argh! yeah, I recall on old hardware or VIA Epias
[03:33:22] <geo01005> P II 400 with 256mb ram...
[03:33:28] <L84Supper> you should be able to catch the updates and turn them off
[03:33:58] <L84Supper> wow, how slow does the system even run with Ubuntu?
[03:34:04] <geo01005> I do want to do the emc updates though, so I'll have to select those manually.
[03:34:08] -!- adb has quit [Remote host closed the connection]
[03:34:31] <geo01005> It is pretty slow, but never hiccups on motion.
[03:34:34] -!- tris has quit [Ping timeout: 246 seconds]
[03:35:23] <L84Supper> I'm surprised it installs, I've had issues with installs on hardware that old
[03:36:30] <geo01005> Well I installed 10.04 a few months ago, and didn't have any problems. I let it do some updates that I didn't see a problem with, but it screw up EMC.
[03:37:10] <SWPadnos> if you had to reboot after updating, then it probably installed a new kernel which was booted by default
[03:37:16] <geo01005> So I though now worries, I'll just backup my config files and reinstall. I'm not a guru with linux, so that sounded easier than trying to fix the conflicts.
[03:37:49] <SWPadnos> you can change the default kernel back to the RTAI one, or manually select it every time you boot (hold shift while GRUB2 is loading, and you'll get a menu, then select the top one that says RTAI)
[03:37:59] <L84Supper> does Ubuntu keep the old kernel in Grub or does it auto erase the older one?
[03:38:06] <SWPadnos> it keeps old kernels
[03:38:38] <SWPadnos> geo01005, did you originally install stock Ubuntu on this machine and then install EMC2 with an install script?
[03:39:02] <geo01005> SWPadnos,Nope, I used the same EMC live CD I used last time.
[03:39:07] <SWPadnos> strange then
[03:39:41] <SWPadnos> so what makes you ask about 10.04.2? did you put a 10.04.2 CD in the drive and upgrade to it?
[03:39:48] <L84Supper> try catching grub and choose the older kernel as he mentioned
[03:41:20] <geo01005> SWPadnos, no when I reinstalled using the old cd and auto updates finished I had to restart and rtai doesn't work. So I looked up what version I had and it had changed to 10.04.2
[03:41:39] <SWPadnos> odd
[03:42:01] <geo01005> The grub screen says that the current system has the 2.6.32-122-rtai kernel
[03:42:18] <geo01005> So I suppose that it didn't do a kernel update.
[03:42:36] <SWPadnos> ?
[03:42:48] <L84Supper> so what doesn't work?
[03:43:16] <SWPadnos> if the computer is booted up, then open a terminal and run "uname -a"
[03:43:20] <geo01005> let me try and start up EMC and I'll post the error message it shows.
[03:43:28] <SWPadnos> that will tell you what kernel has booted
[03:43:43] <SWPadnos> grub will list all the installed kernels, which will include the RTAI kernel from the CD
[03:44:47] <geo01005> Something else that is odd is that the menu at the top of the screen isn't showing up.
[03:45:01] <geo01005> I wonder if my memory has gone bad.
[03:45:14] <SWPadnos> do you remember your name?
[03:45:41] <geo01005> Ha ha.
[03:45:50] <L84Supper> heh, name year and who's president
[03:45:55] <geo01005> it says it booted with the rtai kernel
[03:46:04] -!- tris [tris!~tristan@173-164-188-122-SFBA.hfc.comcastbusiness.net] has joined #emc
[03:46:12] <SWPadnos> president of what?
[03:46:46] <SWPadnos> if the top panel isn't there (and you haven't turned it off or moved it), then there are definitely problems
[03:47:16] <SWPadnos> I'm going to get to bed. here's a page about grub2 configuration: http://ubuntuforums.org/showthread.php?t=1195275
[03:47:34] <SWPadnos> which you probably don't need, since the correct kernel has booted
[03:47:38] <geo01005> the computer has been on non stop for about two years now, So I wouldn't be surprised to hear something has failed.
[03:47:50] <geo01005> Thanks for your help.
[03:47:57] <SWPadnos> you might need to explicitly tell Xorg to use the VESA driver or something
[03:48:11] <L84Supper> yeah, might be time to spend $100 for a new board + RAM
[03:48:43] <geo01005> I have been thinking of getting an atom 330 for about a year now.
[03:48:58] <SWPadnos> also, there may be some issue with DBUS - I have had times when a machine would fail to start DBus or Gnome-Settings or something, and all sorts of things would be screwed up. Log out and back in or reboot (depending on ???) and it would be fine
[03:49:41] <L84Supper> PII board must be 10+ years old
[03:49:59] <SWPadnos> I have a dual PPro-overdrive, if anyone is interested
[03:50:09] <geo01005> http://pastebin.com/XH4ZM24m
[03:50:14] <SWPadnos> (the hopping fast 333 MHz ones too :) )
[03:50:17] <L84Supper> geo01005: slot or socket cpu?
[03:50:47] <L84Supper> I still have a socket to slot adapter brand new in box
[03:50:51] <geo01005> Don't laugh, it is actually a laptop motherboard in a all-in-one computer.
[03:51:03] <SWPadnos> ok, there's a fix for this problem
[03:52:14] <geo01005> Sorry I should have started with that post.
[03:52:43] <L84Supper> I have 4 or 5 AMD K6/3d 366mhz + SiS chipset boards I'll be happy to send to you
[03:52:48] <SWPadnos> http://www.linuxcnc.org/component/option,com_kunena/Itemid,20/func,view/catid,16/id,3971/limit,6/limitstart,12/lang,english/#4020
[03:53:08] <SWPadnos> the quoted text tells you what to do to fix it (so you will need to mess with grub settings)
[03:53:22] <SWPadnos> I think you need to run update-grub as root, but I'm not positive
[03:53:31] <SWPadnos> (it doesn't explicitly say so)
[03:53:36] <geo01005> I'll give it a try.
[03:56:04] <geo01005> rebooting.
[03:56:40] <geo01005> hmm, caplock and numlock lights flashing on the keyboard.
[03:59:42] <SWPadnos> bad
[04:00:06] <geo01005> Still no menu bar, but EMC started up, oh well it got farther...
[04:00:21] <SWPadnos> did you have 10.04 on this machine before?
[04:00:35] -!- JustinXJS3 has quit [Quit: Leaving]
[04:01:03] <geo01005> Yeah, It worked fine for several months.
[04:01:05] <SWPadnos> the lapic thing lets RTAI load, it doesn't do anything for (or against) the desktop problem
[04:01:07] <SWPadnos> ok
[04:01:22] <SWPadnos> anyway - have fun with the desktop. night
[04:01:34] <geo01005> Thanks for your help. Good night.

[04:02:15] <geo01005> The errors I get now really sound like bad memory, can't write to specific memory addresses.
[04:02:29] <L84Supper> geo01005: the caps on that board are pretty worn out
[04:03:16] <L84Supper> might be RAM, the VRM by now is way out of spec
[04:03:46] <geo01005> Yes, I'll bet they are. I'm going to run memtest over the night and see what I get by tommorow night.
[04:04:15] <geo01005> I think the computer is toast.
[04:05:01] <L84Supper> if you have some low-esr caps around you could try replacing some, might breath some life back into it
[04:05:22] <L84Supper> BX chipset by chance?
[04:06:15] <geo01005> I'm not sure.
[04:06:56] <L84Supper> just wondering
[04:07:15] <geo01005> I have a 2.4ghz machine that I was going to used to replace it, but it turns out that it has terrible latency values.
[04:07:32] <L84Supper> what cpu + chipset?
[04:08:21] <L84Supper> did you try all the BIOS settings?
[04:08:28] <geo01005> I don't recall right off, it is an Asus MB with a P4 2.4 celron
[04:09:12] <geo01005> I didn't spend a couple of days on it a few months ago, but I didn't really know what I was doing.
[04:10:37] <L84Supper> I've had boards go from really bad to really good with BIOS changes

[14:12:17] <cradek> In the end software cannot
[14:12:17] <cradek> fix a condition where the motor has trouble keeping up beyond a certain
[14:12:17] <cradek> percentage. Yes, I know, EMC , for example, can do this.. but the methodology
[14:12:18] <cradek> involved is drastically different.
[14:12:54] <skunkworks> :)
[14:14:04] <cradek> some day maybe we'll even hear that Steve B got a good thread
[14:14:06] <cradek> hahaha
[14:14:16] <skunkworks> heh
[14:17:24] <pcw_home> Wow when you have a peculiar hammer, I guess everything looks like a peculiar nail...
[14:21:10] <pcw_home> Theres a brave soul working on a Mach plug-in for our FPGA cards, It was surprising that all the driver gets is a indication of whether you are to step or not each invocation
[14:21:59] <Jymmm> http://www.gearotic.com/
[14:22:13] <skunkworks> I see murphy(sp) has mentioned he is working on it.. But it has been a few years now.
[14:22:15] <cradek> pcw_home: in the event he/she gets it working, who would have to support the resulting mess? I hope not you.

[14:24:35] <skunkworks> some people like reality tv shows....
[14:26:14] <Jymmm> I was considering making a dedicated (PC - less) pocketing/slotting machine, would a PLC be the way to go? Can you input parameters ?
[14:29:08] <Jymmm> Feed it an 8ft 2x4 and get a bunch of 6, 9, or 12" pieces out the other end
[14:29:19] <alex_joni> interesting approach to software QA
[14:29:49] <alex_joni> run it, try to see what the results are, if they are ok-ish, we call the software done
[14:35:35] -!- kb8wmc [kb8wmc!~chatzilla@] has joined #emc
[14:35:45] <pcw_home> Yeah we can only support it the the extent the we will make the firmware do what the docs say
[14:37:30] <cradek> if it's step per invocation, do you still have resolution/top speed tradeoffs based on how fast you can invoke?
[14:38:48] <pcw_home> I'm not sure, It was so ugly that I didn't inquire further
[14:39:16] <anonimasu> pcw_home: question so im sure im not ordering the wrong thing, can my mesa servo board the 400w one handle a 5000 line/rev encoder at 3000rpm?
[14:39:52] <cradek> 5000 wow
[14:40:16] <pcw_home> so 20000 counts per rev? thats 1 MHz at 3000 RPM, easy to do
[14:40:30] <anonimasu> with the ttl inputs?
[14:40:55] <pcw_home> Make sure your encoder can do that (many top out at a few hundred KHz)
[14:40:57] <anonimasu> I expect do to 0.01mm with a 5mm/rev screw within screw precision limits on the lathe so more is better as long as it dosnet limit my speed
[14:42:44] <pcw_home> That will work with TTL encoders (but TTL encoders often suffer from noise problems)
[14:44:03] <anonimasu> the encoder im looking at is a heidenhain encoder
[14:47:43] <pcw_home> Do they have a maximum RPM/Frequency output spec (250 KHz on A or B is the absolute minimum with no allowance for distortion)
[14:47:44] <pcw_home> to get to 3000 RPM with a 5000 line encoder
[14:50:53] <anonimasu> on the phone now
[14:51:17] <anonimasu> 320khz.. way too low
[14:52:50] <pcw_home> is that the A or B max frequency or the max count rate?

[15:01:13] <anonimasu> pcw_home: they said the sensor should deliver 250khz when spinning at 3000rpm
[15:04:32] <pcw_home> right each A and B are 250 KHz square waves in quadrature (90 degrees phase shift) so count rate is 1 MHz wit each edge counted

[15:05:02] <pcw_home> s/wit/with
[15:05:04] <anonimasu> so, the board I ordered from you will do that without a problem?
[15:05:19] <anonimasu> (realistically i will be running at 2000rpm since that's the max for my motors
[15:05:25] <anonimasu> (load speed)
[15:06:07] <pcw_home> No problem (other than possible noise problems with TTL signals)
[15:07:44] <anonimasu> they sell them with 1m cable, so I guess with that cable lengths it should be no problme
[15:07:55] <anonimasu> as long as shielding is proper
[15:08:37] <pcw_home> shielding will definitely help

[17:01:05] <atom1> does linux have a swap space like win?
[17:01:14] <atom1> that may wanna be put there too

[17:03:34] <Jymmm> Swap is used when you have little to no ram, it swaps out memory to the hard drive.
[17:03:41] <atom1> i know
[17:03:48] <atom1> but win is greedy
[17:04:00] <Jymmm> Ok, then why would you suggest it, no matter what OS ?
[17:04:28] <Jymmm> swap will always slow things down.
[17:05:14] <JT-Work> but SolidWorks won't run on linux...
[17:05:25] <atom1> i wasn't really suggesting it, rather wondering the need of it

[18:57:43] <anonimasu> pcw_home: getting worried that I faxed into the wrong place since I didnt get a confirmation yet
[18:58:01] <atom1> anonimasu, did you ever figure out those cutter paths?
[18:58:33] <anonimasu> didnt have time I just threw it into mastercam and cut it

[20:29:36] <mrsunshine_> but damn alot of chips is generated when cutting stuff
[20:29:49] <mrsunshine_> tho i think the wax would be super with liquid cooling as it floats :P

[21:14:52] <KimK> mrsunshine_: What's your latest wax formula? Do you plan any changes to it? How's it working out for you? Got a webpage/blog/wiki on it?
[21:15:09] <mrsunshine_> KimK, as many plastic bags as i can get into the parafin :P
[21:15:46] <mrsunshine_> just pure parafin (from small candle thingies that comes in a alu cup whatever its called) and plastic bags
[21:15:49] <mrsunshine_> and alot of free time :PO
[21:16:00] <mrsunshine_> maybe i will add more free time to it and it will get even better :P
[21:16:41] <KimK> How much paraffin? How many plastic bags? (Grocery-type bags, right? "Paper or plastic?")
[21:17:07] <mrsunshine_> plastic bags, marked LDPE
[21:17:29] <mrsunshine_> KimK, from what i read its 4 to 1 ratio of parafin to LDPE they use
[21:17:37] <mrsunshine_> so 4 parts parafin, 1 part LDPE
[21:17:39] <mrsunshine_> by weight
[21:18:02] -!- psha has quit [Quit: Lost terminal]
[21:19:54] <KimK> OK, thanks. Home canners used to be able to buy paraffin in a big paper-wrapped block about the size of a phone book, I wonder if they offer that anymore? Can you melt pure plastic bags into a big block (100% bags) for storage and measuring convenience, or is that too difficult?
[21:23:08] <KimK> Maybe pour the bags into something tapered for easy removal and re-dispensing, an old muffin tin perhaps? Four paraffin "muffins" and one LDPE muffin go into a pot for making the machinable wax?
[21:23:12] <mrsunshine_> KimK, dont know
[21:23:16] <mrsunshine_> =)

[21:23:43] <mrsunshine_> this is the first times ive experimented with this stuff just to be able to make blocks for carving out stuff to check dimensions and everything without damaging tools =)
[21:24:14] <mrsunshine_> should make a temperature controled auto stired bath for it tho
[21:24:33] <mrsunshine_> so i can set that i want say 140 degrees C, and it just heats it and automaticly stirs it for me =)

[21:26:24] <mrsunshine_> was hoping it would be possible to do lost wax castings with it but i dont know if that will work =)
[21:26:47] <mrsunshine_> tho as its supposed to be self releasing to most resins etc maybe i can cast resin parts using it =)
[21:27:57] <KimK> The old canners used to use a double-boiler to avoid going over 212, as I recall, was that so? A very interesting project, mrsunshine_ , please keep us posted, will you? I think it's worth posting or blogging if you can. Or let me know.
[21:28:25] <mrsunshine_> heh =)
[21:28:58] <mrsunshine_> actualy starting to think about starting my own blog about my machining stuff and experimentation ... as i have a very high need to talk about stuff and my friends etc is getting quite tired of me :P
[21:29:39] <KimK> You should. Lots of ways to do it. I'll help if you need it.

[21:36:49] <atom1> time
[21:36:50] <mrsunshine_> as long as my wax cuts clean and holds its own i will be quite happy with it tho =)
[21:37:00] <mrsunshine_> i need to get a job

[22:45:17] <KimK> mrsunshine_: still around?
[22:47:23] <cpresser_> just a few thougts about the 'pause' button in axis: is it possible to have some commands executed after pause is pressed (goto z-max, stop spindle) and ofc do the same in inverse order as soon as pause is unchecked?
[22:49:07] <JT-Shop> that might not be a desirable thing all the time
[22:49:12] <KimK> cpresser_: What if you were running a slitting saw as a tool?
[22:49:25] <JT-Shop> KimK: :)
[22:49:43] <JT-Shop> or a dovetail tool
[22:49:59] <KimK> JT-Shop: Ja!
[22:50:03] <cpresser_> right, it is not usefull or might even crash a machine, if it isnt a gantry
[22:50:32] <KimK> How would being a gantry save you?
[22:50:59] <JT-Shop> cpresser_: you can make some pyvcp buttons to do each of the things you want after in your brain you determine it is safe to do so
[22:51:31] <cpresser_> but it isnt possible to run mdi-commands in auto mode?!
[22:51:44] <JT-Shop> nope
[22:51:52] <KimK> Or just use the jog incremental, up one inch, up one inch, up one inch,...
[22:52:27] <cpresser_> i already got the pyvcp-buttons; but honestely, i never tryed to use them in auto-mode.
[22:52:51] <cpresser_> somehow i was thinking it is impossible for the interpreter
[22:53:56] <cpresser_> thinking one step ahead, i could create a pyvcp-button which uses halui to pause the interpreter, then run some mdi-commands
[22:54:13] <andypugh> This is nice http://www.carbtune.co.uk/bevel.html No reason for posting it other than it's a nice tool. I reckon I could make one, too, if I wanted to :-)
