[00:01:04] <JT-Shop> was it used as a defensive position sometime in the past?
[00:01:51] <micges> yes
[00:02:14] <micges> and also by monks
[00:02:30] <JT-Shop> we have some caves on a local river that was used as a hospital during the civil war

[00:06:43] <micges> I was thinking that your area is rather flat
[00:06:52] <Tom_itx> hilly
[00:06:59] <Tom_itx> my area is flat
[00:07:00] <Tom_itx> :)
[00:07:22] <jdhNC> I like caves, and diving, and diving in caves.

[00:09:18] <JT-Shop> micges: I'm located on the foothills of the Ozarks
[00:09:34] <JT-Shop> not too far away it is flat as a pancake

[00:11:31] <JT-Shop> zoom out and you can see where the flat ground starts to the south east of me
[00:11:46] <jdhNC> JT: any where near Lake Wappappello?
[00:12:28] <JT-Shop> yea it is 5 miles north, 5 miles east, 5 miles south, 5 miles east, 5 miles north from me
[00:12:37] <jdhNC> heh
[00:12:52] <Tom_itx> fun driving country
[00:12:53] <jdhNC> there is a diveable cave there, close to 300ft deep though
[00:13:02] <JT-Shop> ain't no straight way to get there sept by plane and then you can't land
[00:13:12] <JT-Shop> really what part?
[00:13:35] <jdhNC> it's called cannonball cave, but really Davidson Spring

[01:16:10] <JT-Shop> say goodnight Gracie
[01:20:09] <pfred1> goodnight Gracie
[01:28:11] <andypugh> So, there I was, not reading, and you start talking about caves. Typical.
[01:28:36] <andypugh> (Caving has been a hobby of mine for decades, I used to cave about 3x a week)
[01:29:08] <jdhNC> that't a lot of caving
[01:29:14] <andypugh> (student training trip, fun trip and digging trip every week)
[01:29:22] <jdhNC> in your case, cold and wet I would presume.
[01:29:33] <andypugh> Not counting weekend trips :-)
[01:29:50] <andypugh> Indeed. All my hobbies involve cold and wet.
[01:30:00] <jdhNC> I make 5-8 'caving' trips a year
[01:30:13] <andypugh> caving / sailing / enduro riding / skiing.
[01:33:02] <andypugh> I really need to take up "sleeping"
[01:33:27] <jdhNC> plenty of time for that later.
[01:33:27] <pfred1> andypugh drill a hole in your roof and pray for rain
[01:34:15] <jdhNC> how much oversize do you bore a hole to fit a 3/8" shaft
[01:36:36] <andypugh> Press fit? Sliding fit? Running fit?
[01:36:58] <jdhNC> timing belt pulley on a motor shaft.
[01:37:04] <jdhNC> sliding?
[01:37:20] <andypugh> How is it clamped?
[01:37:40] <jdhNC> two set scews, 90degrees on the pulley, but just one flat on the shaft
[01:37:58] <andypugh> Eeew!
[01:38:45] <andypugh> I would say only use one screw, onto the flat.
[01:39:04] <andypugh> And bore half a thou oversize?
[01:39:15] <jdhNC> heh, I'm not that good.
[01:39:23] <jdhNC> I'll go for nominal and hope :)
[01:40:02] <jdhNC> one should read part dimensions before buying them.
[01:40:17] <andypugh> Just keep boring with no extra cut till it slides on. if it is in a lathe you can try the motor on without taking the pulley out of the chuck.
[01:40:48] <andypugh> For bonus credit bore the hole D-shaped to suit the shaft.
[01:41:14] <jdhNC> how does one do that? broach?
[01:41:19] <andypugh> CNC?
[01:41:42] <jdhNC> if I could cut metal, I wouldn't need to cut metal.
[01:42:16] <andypugh> Not a serious suggestion, sorry. But it is plausible: http://youtu.be/T4q8gCpeY1A
[01:43:46] <jdhNC> nifty.
[01:44:12] <andypugh> A way of getting a lot of torque from a D-shaped shaft (though sadly with high backlash) is to drill a second hole offset from the first and drop a fairly large diameter dowel in.
[01:44:58] <andypugh> I used that to drive some pinion shafts from windscreen wiper motors in my Robotwars robot.
[01:45:51] <andypugh> Partly because there was no access to the pinions for setscrews, and partly because I hate and distrust setscrews anyway)
[01:46:57] <andypugh> Right, sleep time.

[01:51:33] <Tom_itx> what is considered a good press fit on a 1/4" shaft?
[01:51:51] <Tom_itx> and how much expansion can i expect by heating the aluminum that will fit over the shaft?
[01:52:08] <Tom_itx> (and cooling the shaft)
[01:55:49] -!- capricorn_one [capricorn_one!~raffi@zima.linwin.com] has joined #linuxcnc
[01:55:51] <pcw_home> aluminum is 12 uI/inch/deg F so boiling temp would get you 0.3 mills
[01:57:24] toast2 is now known as toastydeath
[01:58:33] <pcw_home> (~130F over ambient) ~350 oven would get you ~double that
[01:58:45] <toastydeath> yeah, our alum oven was 400 f
[01:59:01] <toastydeath> for press fits
[01:59:54] <toastydeath> you'd have to look at the strain information for alum to get the friction, I don't know any of that offhand
[02:00:48] <pcw_home> got to do it fast or you heat up the shaft
[02:01:54] <pfred1> I use some aluminum flashing to keep my tablesaw fence from sliding
[02:02:07] <pfred1> makes all the difference over steel on steel let me tell you
[02:02:25] <jdhNC> I have some liquid He at work... would do wonders for cooling the shaft
[02:03:08] <pfred1> compared to steel aluminum slides like crap
[02:04:52] <Tom_itx> i've done it before with larger shafts
[02:05:48] <Tom_itx> ie timing gears on engines
[02:06:32] <pcw_home> Yeah a 1/4 shaft is going to heat up pretty fast (though aluminum has almost twice the coefficient of expansion of steel)
[02:06:45] <Tom_itx> i may set the hub on the hotplate and have the shaft cool and ready to go
[02:07:04] <Tom_itx> i'll have the depth i want it to slide pre set
[02:07:15] <Tom_itx> i know you only get one shot at it
[02:07:51] <pcw_home> You do want to get it right the first time...
[02:08:03] <Tom_itx> yeah or make a spare :)
[02:08:53] <Tom_itx> will 400F anneal the aluminum?
[02:08:58] <Tom_itx> it's T6 material
[02:09:20] <pcw_home> thats a Q for google
[02:09:27] <Tom_itx> heat treat isn't my strong suite
[02:09:45] <Tom_itx> i have a book i could check
[02:10:31] <jdhNC> http://www.steelforge.com/alloys/?alloy=6061
[02:11:02] <gene__> Hi guys; I should report the the loss of a stack for mdi command I reported for my lathe setup, also is the same for the mill. No idea if that makes it easier or not, but since theres more mill than lathes, I expect it should make it easier to test.
[02:11:34] <Thetawaves> jdhNC, liquid he would be good if you could avoid condensate forming
[02:12:32] <jdhNC> it freezes
[02:13:03] <Connor> jdhNC: Sorry, was out playing with the machine.. I'm by passing the external display.. and have input into EMC...
[02:13:14] <Connor> Trying to understand the values it's returning.
[02:13:30] <Connor> this is just a basic counter.. no index.. 16 per reveolution.
[02:13:37] <Connor> what do I need to look at to get the RPM ?
[02:14:00] <Connor> I'm seeing the velocity like 7.28 etc etc.. way to low to be the RPM.
[02:14:20] <jdhNC> could be pulses per sec.
[02:14:27] <jdhNC> nah, too low
[02:14:40] <Connor> Well.. that was with it set for around 500.. so, that's close.
[02:15:03] <Connor> let me go throw a python component on to see.. brb
[02:15:34] <djdelorie> might be revolutions per *second*
[02:15:39] -!- demacus [demacus!~demacus@erft-d932e6f3.pool.mediaWays.net] has joined #linuxcnc
[02:16:18] <gene__> Also, the wiki page, for the devel version, needs to specify those measurements that effect the thread depth, need to be entered in radius diffs, not diameters. Don't ask me how I know, but it just took me 2 hours to cut a great thread once I had a sharp tool because the diameter reduction was 2x intended, and it was only qadvanceing the bit about .0002 per pass. Duh.
[02:16:22] <jdhNC> could be anything, who knows what he set it for
[02:16:41] <djdelorie> MTBF in years ?
[02:16:55] <jdhNC> revs per micro-fortnights
[02:17:07] <gene__> Conner, I suspect that is RPS, it is here anyway. Multiply by 60 for rpms.
[02:17:08] -!- demacus_ has quit [Ping timeout: 245 seconds]
[02:17:22] <jdhNC> gene: what is that in metric
[02:17:39] <djdelorie> milliseconds per pulse works out about right; 500 rpm would be 7.5 mS if there's 16 pulses per rotation
[02:18:19] <gene__> revs & time aren't diff because its metric
[02:18:46] <jdhNC> 60 doesn't sound very metric. I think you shoudl use 100 seconds, or 1000 anyway.
[02:18:54] <pcw_home> 100 centiminutes
[02:19:06] <jdhNC> yeah, that's it.
[02:19:12] <djdelorie> 10 hours per day, 10 days per month, 10 months per year... I can retire a lot sooner that way!
[02:19:14] <gene__> RPS=revolutions per second.
[02:19:22] <toastydeath> sucks that timekeeping came from the babylonians
[02:19:31] <toastydeath> and they used a base 60 system for most of their mathematics
[02:19:42] <gene__> chuckle, must be getting late.
[02:20:10] <pcw_home> actually 60/12 is kind of nice we just have 2 few fingers
[02:20:21] <djdelorie> well, they had five fingers per hand, and twelve hands per committee...
[02:20:28] <jdhNC> I could use a few more fingers.
[02:20:34] <pfred1> at least the metric weenies haven't gotten to our clocks yet

[02:20:52] <Connor_CNC> okay. on my mill :)
[02:21:00] <jdhNC> rocking
[02:21:11] <djdelorie> we have milliseconds, microseconds, picoseconds... but not kiloseconds or megaseconds. Whew.
[02:21:46] <gene__> and don't forget nanoseconds :)
[02:22:12] <pfred1> that is the time Mork runs on
[02:22:21] <djdelorie> "Hurry up! We haven't got all second, you know!"
[02:22:34] <pfred1> nano nanu
[02:22:37] <Connor_CNC> okay, so how do I link a hal pin to a bar, * 60 ?
[02:23:00] <gene__> Gotta run, my back signed off 2 hours ago. Cheers, guys
[02:23:18] <pcw_home> man scale
[02:23:54] <pcw_home> nite gene__
[02:27:16] <jdhNC> pcw: the .invert_output on my pwm pin fixed the high-after-exiting problem. Thanks!
[02:28:31] <pcw_home> Yeah theres usually a way...
[02:28:57] <pcw_home> also correct for watchdog bite
[02:29:12] <jdhNC> the relays on the board still spaz when speed is set to 1, but that's a board issue I suppose.

[02:30:04] <Connor_CNC> something not right.
[02:31:20] <jdhNC> is spindle-velocity right?

[02:36:35] <Connor_CNC> Pin 'current-spindle-speed' does not exist

[02:39:16] <jdhNC> cool, mpegs?
[02:39:37] <Connor_CNC> later.. I'll upload to youtube soon.
[02:40:22] <jdhNC> make me some ballnut mounts :)
[02:45:33] <Connor_CNC> okay.. how do I get the abs for this.. I.E. loose the decimal place ?
[02:47:58] <djdelorie> Connor_CNC: if it's mSec/rot you need to divide, not multiply. Does the number go *up* if you slow down the spindle?
[02:48:24] <djdelorie> or does it show the right RPM yet?
[02:48:26] <Connor_CNC> djdelorie: I've got the right values now.. I just want to loose the decimal palce.
[02:48:53] <jdhNC> format the value in the pyvcp side?
[02:48:56] <Connor_CNC> wait.. not even that.. I want to smooth it out.. it's bouncing all ove rthe palce.

[02:54:51] <Connor_CNC> It's not too bad using the meter widget
[03:03:08] <Connor_CNC> looks like it's within 8-9 % of commanded speed.
[03:03:13] <Connor_CNC> which is a bit too far out..
[03:04:04] <Connor_CNC> is their a way to use the command speed vs the RPM and have it adjust the PWM output ?

[13:22:40] <jdhNC> anyone used Ethernet/IP with linux?
[13:25:02] <Valen> hrm?
[13:27:17] <jdhNC> should I speak slower? :)
[13:27:50] <archivist> vvveeerrryyy sssllloooowwwwlllyyyy
[13:28:29] <Valen> ok then
[13:28:32] <Valen> yes
[13:29:26] <archivist> in irc it is recommended to ask the real question, not questions about have we done x, should all 102 reply no if not
[13:33:24] <Valen> i've got a bonding, bridging vlan setup right here
[13:34:09] <Valen> and I think i'll stick some kind of vswitch in there too
[13:34:15] <Valen> but later
[13:34:38] <jdhNC> The real question is: Has anyone communicated with an Ethernet/IP device from LINUX.
[13:35:06] <Valen> uhhh, anybody who has used xchat or firefox on their EMC machine i guess?
[13:35:25] <Valen> most of the internet is ethernet/ip
[13:35:27] <archivist> er me Im browsing on a linux box
[13:35:39] <jdhNC> ahhh.
[13:35:41] <Valen> well at least at some point along its trip
[13:35:48] <archivist> and have real wire TM out the rear of the box
[13:36:05] <jdhNC> http://en.wikipedia.org/wiki/EtherNet/IP
[13:36:41] <Valen> to be fair, thats a really dumb name
[13:37:06] <archivist> naming a subset the same as the outer is the dumbest of dumb
[13:38:31] <jdhNC> it seems to be dumb all around
[13:39:02] <jdhNC> it makes it really hard to search for it.
[13:39:41] <Valen> thats one of the main reasons we are calling it dumb
[13:40:03] <jdhNC> but, it's not the same, IP is Industrial Protocol! That makes it all better!

[15:01:00] <JT-Shop> cutting cast iron with a 6" carbide insert fly cutter at 400 RPM what kind of feed per tooth is usual?

[15:02:15] <JT-Shop> steam engine base
[15:02:35] <JT-Shop> I take my brakes to a brake expert when that is needed
[15:02:53] <jdhNC> easier to just get a new vehicle when it needs brakes.

[15:06:26] <jdhNC> I don't see the connection?
[15:06:37] <jdhNC> oh, because they spend money wastefully?
[15:06:51] <jdhNC> I got 130k out of my last set of brakes/vehicle
[15:08:33] <Jymmmm> http://news.cnet.com/8301-17938_105-20005010-1.html
[15:12:55] <Jymmmm> I wish they had those in my area
[15:15:02] <jdhNC> build one!
[15:15:21] <Jymmmm> That aint the problem =)
[15:17:48] <archivist> JT-Shop, getting under the skin quickly is important to save tool life
[15:18:21] <archivist> hope its a good casting with no chills :)
[15:19:28] <JT-Shop> so a depth of cut of 0.015" sound right?
[15:20:04] <archivist> I think so
[15:20:04] -!- nots [nots!~totu@625.radionet.ee] has joined #linuxcnc
[15:20:32] <archivist> depending on casting size etc
[15:20:56] <JT-Shop> I'm taking 0.005" per tooth (only one) for FPT
[15:21:09] <archivist> and will the vibration due to it being a fly be more than x
[15:21:46] <JT-Shop> this is a balanced fly cutter
[15:21:59] <archivist> but cast sounds luverly when its right :)

[20:35:47] <Aero-Tec> hello
[20:36:05] <Aero-Tec> I am trying to get emc to run on my lathe
[20:36:44] <Aero-Tec> running mach now but hate it with a passion but have not got onto how to set up emc
[20:37:02] <Aero-Tec> any help?
[20:37:10] <andypugh> Is it a stepper machine? (I assume so, if youa re using Mach)
[20:37:24] <andypugh> How far have you got?
[20:37:26] <Aero-Tec> I have servero with gecko drivers
[20:37:41] <andypugh> OK, so effectively a stepper machine then
[20:37:41] <Aero-Tec> so it looks like a stepper unit to the computer
[20:37:47] <Aero-Tec> step and dir
[20:37:56] <andypugh> Do you have LinuxCNC installed?
[20:38:12] <Aero-Tec> yes, but it would be a older one
[20:38:28] <Aero-Tec> need to update to the new one it looks like
[20:38:31] <andypugh> That's OK, you can upgrade later, if you want to.
[20:39:09] <Aero-Tec> PP for output
[20:39:15] <andypugh> You probably need to start with Stepconf. Do you have a "CNC" entry in the leftmost-menu items?
[20:39:20] <Aero-Tec> no fancy cards yet
[20:39:43] <andypugh> P-port is probably enough for a 2-axis lathe.
[20:39:56] <Aero-Tec> I can start EMC
[20:40:06] <djdelorie> getting linuxcnc working "at all" with steppers is easy. Then you spend all your time tweaking it, buying better cards, learning new tricks, etc...
[20:40:23] <andypugh> Are you starting it from the command line, or the menu?
[20:40:27] <Aero-Tec> cool
[20:40:33] -!- maximilian_h has quit [Ping timeout: 246 seconds]
[20:40:33] <Aero-Tec> I just need it to run
[20:41:03] <djdelorie> set the stepper speed low, hook up the parallel port to your gecko, and just try stuff with the lathe spindle off. "Turning air"
[20:41:06] <Aero-Tec> I tried the sim lathe from the startup screen
[20:41:13] <Aero-Tec> but that is not working
[20:41:48] <Aero-Tec> I need to program the pins and port address first, right?
[20:41:52] -!- nots has quit [Remote host closed the connection]
[20:42:16] <Aero-Tec> manu
[20:42:16] <djdelorie> When I did mine, I ran through stepconf and wrote down what I picked for each pin, so I could wire it up correctly. The gecko might have a pre-determined pin-function mapping though
[20:42:21] <Aero-Tec> menu
[20:43:02] <djdelorie> so if your gecko has a DB25 on it, the gecko manual should tell you what each PP pin is for. GIve that info to stepconf
[20:43:10] <Aero-Tec> andypugh: menu
[20:43:13] <andypugh> Aero-Tec: There is a utility called Stepconf that will do all the configuration
[20:43:27] <andypugh> You should see it in the same menu as EMC2
[20:43:40] <Aero-Tec> ok
[20:43:56] <Aero-Tec> as for the port I wired it myself
[20:43:57] <andypugh> (But, if you have a very old version of EMC2 then you might have to type "stepfconf" at the terminal prompt instead
[20:44:13] <Aero-Tec> I need to write down the pins

[20:44:26] <andypugh> That starts a wizard that walks you through the process, including setting up the pins.
[20:44:40] <andypugh> Yeah, not down stepper scales and pin assignments from Mach
[20:44:53] <skunkworks__> gene__: I think that must have been a change between 2.5 and master.. I don't think it was a bug.. you might want to post it on the list...
[20:45:11] <Aero-Tec> thanks
[20:45:29] -!- fliebel has quit [Remote host closed the connection]
[20:45:35] <skunkworks__> I just tried 2.5 and it allows you to keep entering mdi while executing. in master - you cannot (the mdi line grays)

[20:47:36] <andypugh> Any questions, feel free to ask.
[20:48:30] <Connor> okay, I need a freaking DPDT relay that can handle 90VDC on the contacts.. 5v coil preferable.
[20:48:58] <djdelorie> reversing the motor?
[20:49:04] <Connor> Yup
[20:49:12] <djdelorie> have you tried searching for an H-bridge with those specs?
[20:49:30] <Connor> Nope. :)
[20:49:43] <djdelorie> might have more luck
[20:50:29] -!- jackc has quit [Ping timeout: 252 seconds]
[20:50:31] <djdelorie> or replace the driver with a reversible one :-)
[20:51:01] <andypugh> Incidentally, a bridge rectifier can be a useful way to protect a motor reversal relay from the motor.
[20:51:24] <Connor> andypugh: Explain ?
[20:51:47] <andypugh> Wire the motor to the AC teminals, and the DC terminals to the correct poer supply leads, and the back-EMF is taken back to the battery, not through relay contact arcs.
[20:52:31] <Connor> Hmm.
[20:52:38] <andypugh> (well, PSU, not battery. My use for it was a Robotwars robot)
[20:52:57] <Connor> I'm thinking about a breaking relay too..
[20:53:00] <Loetmichel> andypugh: a contactor for reverse in a robot?
[20:53:12] <Loetmichel> wouldnt that be a little slow?
[20:53:25] <andypugh> It was actually a 2-pole relay to turn on and off a big whirling disc.
[20:53:30] <Loetmichel> i would use a full h-bridge
[20:53:47] <Loetmichel> ah, not the drive motors
[20:54:01] <andypugh> No, they were through commercial H-bridges.
[20:54:02] <Loetmichel> ok, but still
[20:54:24] <Jymmmm> andypugh: o the bemf is what causes the arcing in the contacts?
[20:54:30] <Jymmmm> so,
[20:54:33] <Loetmichel> at this currents there contacts of EVERY kind have a short life
[20:54:50] <andypugh> The H-bridges we used were £150 each. The peak current draw of the robot was around 250A
[20:55:53] <andypugh> (In fact, the motor drives had DPDT relays on the board anyway, for reversal). This was back when Robotwars was on the TV, probably 15 years ago.
[20:56:05] <Jymmmm> andypugh: So, the bemf is what causes the arcing in the contacts?
[20:57:09] <andypugh> Jymmmm: Yes. That is what creates the high voltage to create the arc.
[20:57:15] <Jymmmm> andypugh: and where does the relay sit in the bridge motor thingy?

[23:18:42] <Aero-Tec> I seen something on TV, big letters WTF, some outfit or company was using that combo of letters for there trade name
[23:18:56] <Jymmmm> LOL ™
[23:19:20] <Jymmmm> (I knew it was somewhere n the dman keyboard =)
[23:19:28] <Aero-Tec> I laughed
[23:19:49] <Jymmmm> Just my 2¢ is all
[23:20:08] <skunkworks__> and for single index threading - you want to use interpolated postion from the encoder.
[23:20:22] <Aero-Tec> andypugh: yes I got the URL

[23:22:00] <Aero-Tec> ok, so how do I reset or find my linux password?
[23:22:09] <pfred1> for root?
[23:22:25] <andypugh> Hmm, is it asking for a password on a LiveCD install?
[23:22:33] <Aero-Tec> I have been hammering on the keyboard forever trying out things I may have used
[23:22:38] <Aero-Tec> yes root
[23:23:10] <Jymmmm> pfred1: £ ≠ $, so no π for you!
[23:23:21] <Aero-Tec> when you do admin things in linux it will askk for the admin or root password
[23:23:28] <pfred1> OK you're going to have to mount your disk with another boot media then edit /mountpoint/etc/passwd and scrub out the password entry
[23:23:33] <andypugh> it might be "ubuntu" and blank password
[23:23:33] <Jymmmm> Aero-Tec: Um, there is no user ROOT unless you made changes.
[23:23:49] <andypugh> Ah, you mean for sudo?
[23:24:00] <pfred1> then your root password will be null so just hit enter and then run passwd
[23:24:18] <Aero-Tec> you lost me
[23:24:18] <r00t4rd3d> ok with a video card installed I get 5000,7000 and with one glxgears session going I get 12,000 and 14,000
[23:24:32] <Jymmmm> Aero-Tec: Are you logged in as yourself?
[23:24:34] <Aero-Tec> I set the password when I did the install over 300 days ago
[23:24:45] <Aero-Tec> not saure what I used
[23:24:48] <Aero-Tec> sure
[23:24:51] <pfred1> Aero-Tec you can crack a local system by booting it up off some other media then mounting the hard drive and editing files on it
[23:24:55] <r00t4rd3d> sudo <command>
[23:24:59] <r00t4rd3d> in a terminal
[23:25:08] <r00t4rd3d> enter your user padd
[23:25:10] <r00t4rd3d> pass*
[23:25:20] <Jymmmm> r00t4rd3d: eay there big guy
[23:25:22] <Jymmmm> easy
[23:25:34] <pfred1> dependong on how yo uhave it setup sudo might ask you for a password
[23:25:45] <Jymmmm> Aero-Tec: What is your username on the system?
[23:25:56] -!- maximilian_h [maximilian_h!~bonsai@93.182.139.193] has joined #linuxcnc
[23:26:00] <Aero-Tec> I did try a empty password
[23:26:10] <r00t4rd3d> is it connected to the internet? Want me to tell you the root pass?
[23:26:11] <Aero-Tec> my name
[23:26:13] <Aero-Tec> stan
[23:26:21] <Aero-Tec> I think
[23:26:24] <pfred1> Aero-Tec you can make it an empty password if you edit the passwd file
[23:26:28] <Aero-Tec> will have to look to make sure
[23:26:33] <Jymmmm> Aero-Tec: are you logged in as 'stan' right now?
[23:26:47] <Aero-Tec> will have to look
[23:27:05] <r00t4rd3d> so how horrible is 12,000 and 14,000 for Max Jitter numbers when glxgears is running?
[23:27:16] <pfred1> r00t4rd3d its OK
[23:27:22] <Jymmmm> r00t4rd3d: under 20KnS is ok
[23:27:25] <pfred1> r00t4rd3d that with your PCI card?
[23:27:31] <r00t4rd3d> yeah
[23:27:37] <pfred1> r00t4rd3d then you're in
[23:27:45] <andypugh> r00t4rd3d: As they say, that's perfectly OK latency.
[23:27:49] <Jymmmm> r00t4rd3d: less than 20,000nS is ok, above that is questionable
[23:27:57] <pfred1> anything under 20K is OK
[23:28:24] <pfred1> but at 20Kyou're not going to run crazy microstepping modes
[23:28:49] <andypugh> You can drive a stepper faster than a stepper can go with that latency.
[23:28:50] <r00t4rd3d> If i run glxgears and firefox my numbers goto 25k,27k
[23:29:07] <pfred1> I think ¼ or 1/8th is about the limit
[23:29:11] <Jymmmm> r00t4rd3d: not good
[23:29:11] <andypugh> Still bearable. I have a 40k machine and that's OK
[23:29:24] <Jymmmm> andypugh: Ha! =)
[23:29:26] <pfred1> yeah run in half step mode
[23:29:30] <andypugh> (though only 1/4 step)
[23:29:40] <Jymmmm> andypugh: ah, ok
[23:30:12] <pfred1> anything other than full seems to avoid resonance to me
[23:30:14] <Jymmmm> andypugh: I take back by Ha!, and replace it with a ho!
[23:30:17] <andypugh> Running the text-based latency test in the RTAI folder I get 1300 for this machine. I am unconvinced.
[23:30:36] <r00t4rd3d> I have 1 - 1/2 - 1/8 - 1/16 MicroStep Settings
[23:30:49] <Jymmmm> andypugh: really? Wow, that's super low
[23:30:55] <pfred1> andypugh ther are a couple text based RTAI latency tests
[23:31:02] <andypugh> As I said, I am not convinced
[23:31:09] <Jymmmm> andypugh: no doubt
[23:31:50] <Jymmmm> r00t4rd3d: you might get better results if you enter your BIOS and disable the things you won't be using. FDD, serial ports, etc.
[23:32:01] <r00t4rd3d> when emc2 starts it gives me a list of setups to choose from, anyone know what I pick for a 3 axis TB6560
[23:32:17] <pfred1> poke your eyes out and smash your video card
[23:32:28] <r00t4rd3d> ok Jymmmm I will do that
[23:33:01] <andypugh> r00t4rd3d: Instead of using a sample config, run stepconf to configure for your owb machine.
[23:33:04] <Jymmmm> r00t4rd3d: even secondary drive controllers if you aren't using them.
[23:33:38] <pfred1> andypugh I ran stepconf and made my machine the default config
[23:34:38] <r00t4rd3d> sucks i have to use 8.04
[23:34:42] <pfred1> r00t4rd3d I use TB6560AHQ motor drivers
[23:35:10] <pfred1> what really sucks is most of the Lenny repos are gone today
[23:35:54] <Jymmmm> pfred1: ISO's?
[23:36:19] <pfred1> Jymmmm doesn't help much for aptitude safe-upgrade or adding new software
[23:36:36] <pfred1> there are still a couple out there though
[23:36:50] <pfred1> no official ones they all got taken down
[23:36:58] <andypugh> r00t4rd3d: 8.04 is OK, and you can still run the latest LinuxCNC version
[23:37:21] <pfred1> what is the latest kernel RTAI can be patched against?
[23:38:11] <Aero-Tec> Jymmmm: yes I am logged in as stan right now
[23:38:37] <Aero-Tec> I think I set up stan with admin priv

[23:39:12] <Jymmmm> Aero-Tec: type: sudo passwd root<ENTER>
[23:39:17] <djdelorie> Aero-Tec: in a terminal window, type "sudo date" and see if it works
[23:39:39] <djdelorie> (or passwd ;)
[23:39:43] <pfred1> I've erased my root password on boxes I forgot the password on
[23:39:44] <Aero-Tec> can I just down load the new version and install over this old version?
[23:40:14] <pfred1> you have to boot it off other media then mount the HDD then go in and edit the passwd file
[23:40:25] <pfred1> remove the password field for root
[23:40:28] <r00t4rd3d> what do I want my parallel port option set at? I have like 3 listing in bios, ECP , EPP etc
[23:40:30] <Aero-Tec> so type in passwd, not the password I set up
[23:40:31] <andypugh> Aero-Tec: Might be easiest. In fact make a copy of the EMC/configs/lathe folder, then download the LiveCD and do a nuke-from-orbit install?
[23:40:41] <Jymmmm> Aero-Tec: correct
[23:40:44] <pfred1> passwd is the command to change your password
[23:40:51] <Jymmmm> Aero-Tec: it will ask you for a NEW password
[23:40:57] <pfred1> but you can't use it if yo udon't know yoru password
[23:41:10] <Jymmmm> pfred1: Yes, he can.
[23:41:23] <pfred1> passwd asks you for your old one
[23:41:34] <pfred1> either that or you have ot be the user
[23:41:49] <Aero-Tec> will try
[23:42:03] <Jymmmm> Aero-Tec: ignore pfred1 for a moment and try what I suggested
[23:42:24] <Aero-Tec> I like the nuke from orbit idea
[23:42:29] * pfred1 doesn't change his passwords all that often well never
[23:42:29] <Aero-Tec> ok
[23:42:31] <Aero-Tec> will do
[23:43:26] <pfred1> Aero-Tec I can explain in enough detail what you need to do in order to alter your filesystem to remove your password
[23:43:28] <Jymmmm> pfred1: the use of 'sudo passwd blah' is just like being root changing a user's password, the old one isn't needed.
[23:43:47] <pfred1> how can you sudo if you don't know the password?
[23:43:48] <r00t4rd3d> glxdmesg
[23:44:00] <r00t4rd3d> whooops
[23:44:12] <pfred1> I always set root as my user's password
[23:44:14] <r00t4rd3d> i hate having 2 keyboards in front of my
[23:44:22] <Jymmmm> pfred1: initial user on ubntu have sudobility by default
[23:44:53] <pfred1> then do sudo -s
[23:45:23] * Jymmmm kicks pfred1 in the ass and hands him a cookie!
[23:46:11] <pfred1> which is mostly all I ever do for root anyways
[23:47:03] <pfred1> you can edit visudoers and make your main user root anyways
[23:47:44] <Aero-Tec> Jymmmm: it asks me for stans password
[23:47:52] <Aero-Tec> witch I do not know
[23:48:14] <pfred1> Aero-Tec how are you logged in as stan? autologin?
[23:48:22] <Aero-Tec> stan
[23:48:46] <Aero-Tec> but it does not ask for password on startup
[23:48:56] <pfred1> you autologin
[23:48:59] <Aero-Tec> thank god
[23:49:22] <Aero-Tec> says stan in the top right corner
[23:49:39] <pfred1> then run passwd as stan
[23:50:00] <Aero-Tec> tell me what to type in
[23:50:10] <Aero-Tec> please
[23:50:36] <pfred1> yeah passwd asks you for your password
[23:50:41] <Aero-Tec> sudo passwd stan?
[23:50:42] * pfred1 just ran it
[23:50:53] <pfred1> it won't help unless you know your current password
[23:51:30] <Aero-Tec> I have windows on this box as well
[23:51:42] <pfred1> Aero-Tec this may sound crazy but it worke better than I'd think it would you can overlay install Linux
[23:51:57] <pfred1> it doesn't seem to hurt it too much
[23:52:10] <pfred1> run install again but don't let it format your partitions
[23:52:46] <pfred1> but when it comes time to tell it a password pay some attention
[23:53:07] <Aero-Tec> how about just downloading the new live disk and installing that
[23:53:20] <pfred1> you could do that too but save your configs
[23:53:31] <Aero-Tec> it would be the new 2.5 and fix the pass code problem
[23:53:43] <pfred1> yes it would
