[02:14:40] <DJ9DJ> moin
[03:12:12] <mrsun_> hmm backlash in the Z axis is a strange little beasty isnt it? :P
[03:12:20] <mrsun_> atleast if you try and compensate it :P
[03:14:42] <archivist> need to remove/fix stiction
[03:16:22] <mrsun_> archivist, ye but if i losen up the head so it will freefall its to lose for milling :P
[03:16:38] <DJ9DJ> re
[03:18:27] <mrsun_> i could just make a antibacklash nut but the bastards have made left handed thread on the Z axis screw :P
[03:19:37] <archivist> lh is nearly as easy on a lathe :)
[03:20:59] <mrsun_> archivist, i guess, but its like an M8 nut :P
[03:21:04] <mrsun_> i guess i could make a tap
[03:21:16] <mrsun_> and make a antibacklash nut out of delrin or something
[03:23:48] <mrsun_> annoying thing with stiction in the Z is that when moving down to a cut the backlash gets Z in the downstroke, then you start cutting and it falls down like 0.1mm more :P
[03:37:51] <Jymmm> Does anyone know anything about flywheels? In a nutshell, in a hand crank situation, would it be beneficial? Drawbacks?
[03:38:39] <Jymmm> Could I use a "container" and fill it up with water as needed for the mass?
[03:41:00] <archivist> hehe no
[03:41:14] <Jymmm> what if I "gel" the water
[03:41:35] <archivist> use a lump of a real solid
[03:41:58] <Jymmm> sand in a compartmental "mass"?
[03:42:11] <Jymmm> like a sliced pie.
[03:42:17] <archivist> no
[03:42:21] <archivist> use a solid
[03:42:47] <Jymmm> ok, solid. what about the benefits/drawbacks?
[03:43:01] <archivist> the forces in flywheels need some understanding
[03:43:33] <Jymmm> I'm thinking like the old foot powered sewing machines http://farm4.static.flickr.com/3607/3458383777_ac04f5fc68.jpg
[03:44:09] <Jymmm> It had a 12-14" wheel, I guess that was the mass.
[03:45:41] <Jymmm> Darn, no large images http://www.hipgallery.com/photopost2/data/500/15treadle.jpg
[03:46:39] <Jymmm> I used one of those a long time ago, it took very little effort, and your foot only traveled about 3" total.
[03:47:47] <archivist> a sewing machine needs little effort, it having a flywheel has no relation
[03:49:07] <R2E4> Hi guys. I am looking for some direction. I have a Bridgeport series 1 R2E4 boss 9 coming 2 march and I want to strip the elecs and put a new system in and use existing servo motors and encoders.
[03:49:42] <archivist> the flywheel is like a capacitor in a power supply, you provide intermittent power and the flywheel accepts the power and gives it out smoothing the action
[03:50:07] <Jymmm> stored mechanical energy
[03:50:14] <R2E4> I dont want to use step and dir, so am turning to LinuxCNC. I am trying to find one of the documented bords that would talk to the servo's.
[03:50:35] <archivist> R2E4, keep lurking I think others have done those too
[03:50:43] <Loetmichel> moin
[03:50:55] <Loetmichel> ups... mornin'
[03:51:33] <archivist> R2E4, most use mesa cards for servo systems
[03:52:26] <R2E4> OK, I'll start reading up on those.
[03:52:41] <archivist> R2E4, your existing servo amplifiers may be usable, so dont throw those too quickly
[03:53:11] <R2E4> I thought of that but what about reliability?
[03:53:40] <R2E4> I really don't want to have to worry about them blowing in a month or so after upgrade.
[03:53:49] <archivist> that I do not know, but some retro fits retain the amps
[03:54:15] <Jymmm> archivist: Basically what I want to do is use something like a drum peddle to crank a dc motor to generate electricity
[03:54:26] <R2E4> I'll keep that in mind..... thanks
[03:54:43] <Jymmm> archivist: Thus where the flywheel or just a large wheel (like the sewing machine) comes into play.
[03:55:23] <Jymmm> archivist: It's just a twist on the old hand crank generators.
[03:55:29] <archivist> Jymmm, just use a bicycle frame
[03:55:38] <Jymmm> archivist: Has to fit into a backpack.
[03:56:05] <R2E4> That would be a big backpack....
[03:56:11] <archivist> see the hand shake chargers
[03:56:38] <Jymmm> archivist: LOL, I have one of those flashlights.... phuk me, and it has a 1F cap in it =)
[03:56:44] <archivist> generating a reasonable amount needs effort
[03:57:27] <Jymmm> sure
[03:58:19] <archivist> flywheels are heavy
[03:58:23] <Jymmm> archivist: Got the idea from this 60s video http://www.youtube.com/watch?v=RgRT6WAStaE
[03:58:38] <Jymmm> archivist: Right, thus the water/sand/etc
[03:58:43] <cncbasher> R2E4:http://gnipsel.com/shop/bp1/bp1.xhtml
[04:01:23] <R2E4> cncbasher: thats badaass
[04:01:32] <R2E4> Is it done?
[04:01:59] <cncbasher> yea , it's JT's
[04:02:21] <R2E4> Servo's or steppers?
[04:02:22] <cncbasher> bridgeports are pretty easy
[04:02:30] <cncbasher> servo's
[04:02:48] <R2E4> ooooooohhh. Now this is getting interesting.
[04:03:07] <R2E4> mesa boards?
[04:03:13] <cncbasher> yea
[04:03:36] <R2E4> ok, I need the address of his hsop and the keys so I can take a look at it....hehe
[04:04:01] <Jymmm> ...and kevlar.
[04:04:20] <cncbasher> you'll need a few pry bars too
[04:04:27] <R2E4> is he happy with it the way it turned out?
[04:04:48] <cncbasher> he'll be showing up here shortly
[04:05:01] <Jymmm> about 2-3 hours
[04:05:41] <cncbasher> JT-SHOP: R2E4 would like info on convertion of bridgeport
[04:05:41] <R2E4> I am going to install linuxcnc today.
[04:06:11] <Jymmm> R2E4: Run the latency test from the LiveCd BEFORE you install
[04:06:37] <R2E4> I haven't used lnux since slackware 1.1 kernel so it might be interesting......
[04:07:13] <Jymmm> R2E4: Not all mobos can be used. and ost all laptops can NOT be used, though many try.
[04:07:23] <Jymmm> s/ost/most/
[04:07:49] <R2E4> I will get a box that will work. If I dont have one I will get one.
[04:08:41] <R2E4> Will the latency test give me a yah or nay or just a number?
[04:09:02] <Jymmm> a number, and run it for a minimum of 24 hours.
[04:09:36] <Jymmm> load up the machine, run everything, you want to kick the tires heavily
[04:10:09] <R2E4> Do I need to have the mesa cards in it or is this strickly to test the mobo etc...?
[04:10:18] <Jymmm> just the mobo
[04:10:39] <cncbasher> R2E4:http://wiki.linuxcnc.org/uploads/Title_Sheet.pdf
[04:13:19] <R2E4> COOL, thanks...
[04:13:49] <R2E4> I will have to read up on the mesa stuff tomake sure it willdrive my servo's and understand the encoders.
[04:14:05] <R2E4> But that is a great step inthe right direction cncbasher
[04:14:15] <R2E4> thanks
[04:16:40] <R2E4> so coming out of the 7i33TA's, is the servo amps and the encoders. So these boards handles the loop to close it or is that linuxcnc?
[04:16:44] <cncbasher> R2E4: the only point to clarify is if the servo motors are using encoders or resolvers
[04:17:01] <R2E4> they are encoders.
[04:17:27] <cncbasher> that will denote if a addon card is needed ,
[04:17:32] <R2E4> not very high resolutino I might add.
[04:17:46] <R2E4> resolution
[04:19:37] <cncbasher> linuxcnc handles the closed loop , the mesa cards is the interface between them
[04:19:51] <R2E4_> gotcha
[04:20:01] <Jymmm> R2E4: http://www.youtube.com/watch?v=2E3PMooch1k
[04:21:24] <Jymmm> R2E4: http://electronicsam.com/images/KandT/conversion/panel/electricalbox.jpg
[04:21:35] <R2E4_> Is that a 4th axis doing that tapping?
[04:21:48] <R2E4_> 1" that fast.... impressive
[04:22:47] <Jymmm> http://electronicsam.com/images/KandT/oldkandt.JPG
[04:23:03] <Jymmm> It's like 8ft tall
[04:24:59] <R2E4_> jesus.... That thing is lethal
[04:25:04] <Jymmm> http://www.youtube.com/watch?v=Kh4YD0d071c
[04:25:29] <Jymmm> http://www.youtube.com/user/samcoinc/videos
[04:26:06] <Jymmm> skunkworks: you need to take video zoomed out
[04:27:04] <Jymmm> http://www.youtube.com/watch?v=CYA5uEwLSTA
[04:30:36] <Jymmm> R2E4: latency test running in the TL corner http://www.electronicsam.com/images/KandT/testing/asus%20m2n68-am%20plus%20motherboard%20with%20amd%20phenom%20x4%209600b%20%28quad%20core%202.3ghz%29.jpg
[04:32:49] <R2E4_> how many tools do you need to be able to use? haha damn!
[04:33:56] <R2E4_> latency test not found
[04:34:25] <Jymmm> R2E4: CNC Pr0n (not linuxcnc), LOTS-O-TOOLS http://www.youtube.com/watch?v=A_qHR_H_2cg
[04:35:07] <Jymmm> like 85-150 tools iirc
[04:37:59] <R2E4_> wow. I want one of those.
[04:38:33] <cncbasher> R2E4:http://igor.chudov.com/projects/Bridgeport-Series-II-Interact-2-CNC-Mill/
[04:38:47] <Jymmm> R2E4: Talk to your electric company first.
[04:39:38] <cncbasher> anyone have plans for a diy power station
[04:39:53] <Jymmm> cncbasher: yes
[04:40:05] <R2E4_> I'd hate to be the guy that had to program that CTX gamma 2000.
[04:40:34] <Jymmm> cncbasher: or do you mean like blueprints?
[04:40:47] <Jymmm> CAD files, etc
[04:41:36] <cncbasher> yea the way things are going in the UK we wont have enough electric to run
[04:42:05] <cncbasher> anything , the way the cost is rising
[04:42:25] <Jymmm> is it imported?
[04:42:33] <R2E4_> same SEM motors on mine.
[04:43:41] <cncbasher> R2E4_: sem are common motors on a bridgeport
[04:44:02] <Jymmm> cncbasher: Heh, you need to harness the power of FOG!!!
[04:44:26] <archivist> cncbasher, I have a 6 cyl deseasal generator resting and waiting for use :) 60A 3 phase
[04:44:28] <cncbasher> keep the origional servo drives if they are working , makes for a simple conversion with mesa cards
[04:44:59] <cncbasher> archivist> i have a long extension lead
[04:46:07] <R2E4_> then just change the controller?
[04:46:39] <R2E4_> otherwise I would need servo amps...........
[04:46:44] <cncbasher> R2E4_ : yes thats all you need
[04:48:23] <R2E4_> that interact didn't look bad at all. Electronics I mean.
[04:48:24] <Jymmm> cncbasher: Make like a giant version of this, then use the weight of the rainfall to "squeeze it" =) https://www.youtube.com/watch?v=_N5QBoE1Zxs
[04:48:45] <cncbasher> R2E4:use mesa 5i25 pci card and the servo addon card and gpio pendant card perhaps and your done
[04:50:19] <Jymmm> cncbasher: OH, stack and cascasde them... water in the first, empties into the next, etc.
[04:50:43] <cncbasher> Jymmm: i''l just have the wife pedal the bike , whilst i'm milling
[04:51:06] <Jymmm> cncbasher: there ya go =)
[04:51:35] <Jymmm> cncbasher: what about a wind generator?
[04:51:35] <cncbasher> jymmm: might make her feel useful .. hehehe
[04:51:49] <JesusAlos> hi
[04:52:32] <Jymmm> cncbasher: If we had as much rainfall as you guys do, and had the land, I'd try the squeeze thing.
[04:53:06] <Jymmm> cncbasher: They does those for real using a water tank on a hill.
[05:27:36] <mrsun_> hmm need to make a longer screw for the tailstock i think
[05:27:53] <mrsun_> if i put a dead center in there i have to unthread it all, pull it out and push it out with a tool :P
[05:39:59] <mrsun_> hehe china machine screws are a joke :P
[05:40:13] <mrsun_> stripped the threads off one without any effort
[05:48:54] <jthornton> archivist, I got to use my 15kW generator Thursday during the ice storm
[05:49:30] <archivist> mine has been resting for many years
[05:49:56] <archivist> needs a battery
[05:50:12] <cncbasher> archivist:time to give it a clean and use it
[05:50:30] <archivist> the fuels costs enough!
[05:51:02] <jthornton> mine is a 2 cylinder Deutz air cooled diesel
[05:51:18] <archivist> we used to use it as a museum for site power for a number of years, the whip round for fuel money was fun
[05:51:58] <archivist> I have a Perkin6 6.354 on mine 100hp ish
[05:52:10] <archivist> Perkins
[05:52:28] <jthornton> that would be hard to hand crank
[05:53:00] <jthornton> a hydraulic starter would be better than a battery starter for a back up generator IMHO
[05:53:31] <archivist> fun was when it would run out while a person was in a boiler flue needle gunning the rust, poor bugger has to get out in the pitch black
[05:54:21] <jthornton> I used to hate when the needle gunners worked near me in the shipyard
[05:54:33] <roh> is the grid really that unreliable where you are that spare diesel generators are in order?
[05:54:55] <archivist> americans need backup power :)
[05:55:15] <Jymmm> jthornton: hydralic starter?
[05:55:45] <jthornton> yes, the grid is for the most part on overhead lines and I live in a forest...
[05:56:12] <Jymmm> jthornton: what is a hydraulic starter?
[05:56:14] <jthornton> Jymmm, yes a common thing for diesel engine
[05:56:46] <Jymmm> hand pumped hydraulics?
[05:56:47] <archivist> or a spinning flywheel on a no-break gen set
[05:56:56] <jthornton> a hand pump, a hydraulic motor an accumulator, and a lever
[05:57:02] <Jymmm> ah
[05:57:15] <Jymmm> Just never heard of such a thing.
[05:57:22] <jthornton> if the accumulator is pressured up you just kick the lever to start the motor
[05:57:35] <jthornton> if not you pump your ass off then kick the lever
[05:57:42] <Jymmm> heh
[05:57:54] <roh> hydraulic starters seem fancy
[05:57:58] <archivist> also a lot have air start
[05:58:01] <jthornton> I know Detroit Diesel had them
[05:58:14] <roh> just i guess its the same amount of work to maintain them like its for batteries
[05:58:18] <jthornton> the EMD
[05:58:19] <Jymmm> and hope it starts the first time?
[05:58:24] <jthornton> 's had air starters
[05:58:27] * Loetmichel hat compressed aur starters on the Diesel engine at the navy
[05:58:30] <jthornton> yep
[05:58:46] <Loetmichel> 3500 HP 16 cyl turbodiesels
[05:58:54] <Loetmichel> air
[05:59:22] <Loetmichel> 2 engines, 2 "cans" with 120 liters 60 bar compressed air each.
[05:59:26] <roh> i guess batteries are easier to maintain without proper training. every car mechanic knows such stuff. hydraulic starters only people know who work on big engines
[05:59:35] <Loetmichel> just enough for 3 start-trials
[05:59:47] <archivist> I used to play with a Brush opposed twin with air start and a 3 ton flywheel on it
[06:00:24] <Loetmichel> if these failed: go in the stern of the ship, handcrank the 2 cyl 10hp diesel air compressor to life, wait 2 hrs ;-)
[06:00:32] <Jymmm> roh: I'm hearing more and more ppl are installing lil solar panels on their rarely used gear to maintain the battery making it last 3+ years
[06:00:52] <jthornton> the hydraulic starters were on 12 cylinder engines, not so big about 4' tall or so and 8' long V12's
[06:00:55] <Jymmm> roh: tractors, snow mobiles, riding mowers,e tc
[06:02:16] <roh> Jymmm: thats an option if you got them standing outside all the time
[06:02:30] <Jymmm> long cable
[06:02:45] <roh> then you can also hook em up to the grid
[06:03:28] <Jymmm> nah, no fun in that
[06:04:11] <Jymmm> Heh, diesel MC http://www.dieselbike.net/privateproduction/dieselchopper.jpg
[06:04:27] <roh> dont get me wrong.. i like solar. but it think its a sign of wrong thinking if one only uses it to maintain batteries used to start gas guzzlink gear
[06:04:54] <Jymmm> as opposed to what?
[06:04:55] <roh> so i'd rather see solar powering a local grid which you can also hook up battery chargers to
[06:05:25] <Jymmm> I'd rather get OFF THE GRID =)
[06:05:36] <Jymmm> under the radar too =)
[06:37:31] <jthornton> pcw_home, do you have a link for a 7i77 sample ini file too?
[06:50:27] <jthornton> pcw_home, nevermind cncbasher found it on my web site
[07:56:33] <Loetmichel> hmmm, can anyone give me a tip how to display the CPU temp in LinuxCNC-ubuntu 10.04?
[07:56:56] <Loetmichel> the HDD i got, but the tool doesent show the CPU as sensors. somewhere i have mised something
[07:57:07] <cncbasher> see the wiki i'm sure theirs an example
[07:59:29] <Loetmichel> seen none. do you have a link to the specific wiki page? maybe i should search better ;-)
[07:59:51] <cncbasher> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?ContributedComponents#Motherboard_Sensors
[08:01:34] <Loetmichel> wrong end
[08:02:16] <Loetmichel> i dont want to see them in linuxCNC, just in the title bar of Gnome. but the acpi sensost doesent show, so the .py will not help
[08:03:07] <cncbasher> ok understand now
[08:03:34] <Loetmichel> the only sensor the sensor applet can see is the HDD
[08:04:11] <cncbasher> what cpu and motherboard are you using
[08:04:26] <Loetmichel> core2duo 2.53 ghz
[08:05:07] <Loetmichel> and a Kontron kt965/flex
[08:06:10] <cncbasher> have you try'd using lm-sensors ?
[08:06:33] <Loetmichel> it is installed iirc
[08:07:22] <cncbasher> no
[08:07:44] <cncbasher> sudo apt-get install lm-sensors sensors-applet
[08:08:19] <cncbasher> the other i am aware of is computertemp
[08:08:27] <Loetmichel> done that a while ago
[08:10:23] <cncbasher> http://www/lm-sensors.org
[08:11:09] <Loetmichel> hmmm... just run the sensors-detect-script ... CNC rebooting... lets see...
[08:11:29] <cncbasher> http://www.lm-sensors.org/
[08:12:06] <Loetmichel> its not like i NEED thos temps, but as the lid of the pizzabox is 2mm abvove the coufan i feel safer to see the temps ;-)
[08:12:24] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12265
[08:12:29] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12250
[08:12:35] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12247
[08:12:40] <cncbasher> yea it's close
[08:12:47] <Loetmichel> its a BIT crammed inside there ;-)
[08:13:23] <Loetmichel> ha, FINE.... sensords-detect did the trick
[08:14:23] <cncbasher> great
[08:15:50] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14061
[08:16:03] <Loetmichel> .... note to self: installing is sometimes not enough ;-)
[08:17:08] <cncbasher> glad u have it all working
[08:19:19] <Loetmichel> thanks
[08:19:49] <Loetmichel> now i just have do dismaltle the CNC bcause one of the couplers is slipping.. (y axis) :-(
[08:20:54] <Loetmichel> should make me some new ones from aluminium, the POM ones are not as sturdy as thought, had to repair the x coupler some time ago as well :-( -> http://www.cyrom.org/palbum/main.php?g2_itemId=12563
[08:21:00] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12566
[08:22:02] <cncbasher> yes cant beat aluminium ones
[08:24:59] <Loetmichel> i am a bit shy of aluminium for the couplers because of the bending that occurs, dont the alu weaken over time?
[08:25:39] <Loetmichel> or should i use this style: http://www.cyrom.org/palbum/main.php?g2_itemId=12846 ?
[08:26:04] <cncbasher> if your shafts are central and axialy in line you should not have any problem
[08:26:16] <cncbasher> iv'e never had one break
[08:26:39] <Loetmichel> ok...
[08:27:20] <cncbasher> if you have a slight difference in axial direction then the last one would be better
[08:27:52] <cncbasher> but i have some huge ones on 3 machines and never had a problem
[08:28:05] <Loetmichel> then i will tighten the y coupler and begin to make some youplers wit the slots in it from aluminimum rod... $me is searching for his mini saw blade and mount for the spindle ;-)
[08:28:10] <cncbasher> there 100mm long and 50mm dia
[08:28:29] <Loetmichel> mine are a lot smaller
[08:29:00] <Loetmichel> about 16mm dia and 40mm long
[08:29:14] <Loetmichel> its a small machine, also ;-)
[08:29:21] <cncbasher> dont worry they will be fine
[08:29:31] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14043
[08:29:46] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14040
[09:18:14] <jensor> I've found a solution to fixing the problem of one axis limiting the velocity on a single axis G0 call.
[09:19:00] <jensor> Just configure the fastest axis as [AXIS_0]
[09:19:32] <jensor> Because that axis limits the others
[09:27:40] <archivist> that looks like a bug
[09:29:44] <skunkworks> I have not run into that. I know that the K&T has its max velocity as sqr(x^2+y^2+z^2)
[09:32:18] <Jymmm> log(r2d2^c3p0)
[09:34:59] <Jymmm> skunkworks: How did you determine that?
[09:47:24] <skunkworks> because that is what I calculated - if all axis are moving at max velocity - its combined velocity is sqr(x^2+y^2+z^2)
[09:47:44] <rizo> i would like to control linear bldc motor using bldc.comp. I configured the hal so that i can home the motor. The problem is that when i set the bldc. value to some max value, the motor does not accelerate, but just stays still. If i print the bldc.output i can see the 90deg lag between the phase angle and rotor angle. Why is the motor not moving than?
[09:48:26] <Jymmm> skunkworks: So that's basically theoretical, not actually one axis being slower than the others?
[09:48:29] <rizo> The motor stays still with the current set to maxvalue.
[09:51:16] <skunkworks> well - linuxcnc when G0'ing - is showing correctly
[09:54:22] <Jymmm> skunkworks: k
[10:33:00] <cradek> I can't reproduce that problem and I replied on the forum saying exactly what I did to test it.
[10:33:49] <cradek> I did not try stepper because I do not have realtime here. but if it was a stepper maxvel setting problem, you'd get an ferror right away.
[10:34:47] <skunkworks> my thoughts exactly
[10:35:22] <skunkworks> his ini and hal file look ok - It seems as if the max velocity setting in the traj section isn't being read.
[10:36:18] <cradek> someone in the forum suggested maybe he isn't running the config he thinks he is. I've done that. it might be some silly problem like that...?
[10:37:21] <cradek> trying to reproduce it in sim, making minimal changes to one of the sim configs shipped with 2.5.1, would be a great idea
[10:45:43] <r00t4rd3d> cradek, will you code up a android app that streams linuxcnc's preview window with a estop button?
[10:45:44] <r00t4rd3d> :)
[10:47:06] <r00t4rd3d> probably do that with mini emc2 i guess
[10:48:12] <cradek> no, I won't. I only use my powers for good, never for evil.
[10:48:21] <cradek> (and only occasionally for silly)
[10:48:24] <JT-Shop> lol
[10:48:58] <Jymmm> cradek: He said andriod, not iPhone
[10:50:25] <r00t4rd3d> http://code.google.com/p/miniemc2/wiki/PageName
[10:51:00] <pcw_home> rizo: this probably means you have an error with commutation (commutation angle should lead/lag magnetic null by 90 degrees depending on sign of BLDC input)
[10:53:33] <Jymmm> pcw_home: Please rephrase your last statement in a geek format
[10:55:50] <Jymmm> Why would aluminum welds be painted?
[10:57:33] <r00t4rd3d> hide the cracks
[10:58:24] <Jymmm> I picked up a 6ft section of datacenter cable management railing (kinda looks like a ladder hanging horizontally from the ceiling) and where the "rungs" are welded to the channel it's painted, but nowhere else.
[10:58:54] <r00t4rd3d> black?
[10:58:59] <Jymmm> no, silver
[11:04:46] <r00t4rd3d> probably just anodized
[11:07:10] <r00t4rd3d> see if some will scrap off with a knife
[11:07:36] <R2E4> Hey guuys....
[11:07:40] <r00t4rd3d> if it dont, its anodized
[11:08:21] <R2E4> Will a 1.8ghz 2core 2 gig ram computer work ok with linuxcnc?
[11:08:37] <r00t4rd3d> need more info then that
[11:09:08] <r00t4rd3d> i got an android tablet with those specs
[11:09:32] <skunkworks> R2E4: yes - if it performs well with realtime
[11:10:03] <skunkworks> throw the livecd in it and test
[11:10:29] <r00t4rd3d> R2E4, are you looking at buying one or getting a old one going?
[11:10:41] <R2E4> yeah, I'm downloading now but I dont thinki it is the live cd....hehe
[11:11:32] <rizo> pcw_home, can i somehow offset the rotor angle? I am using software commutation.
[11:11:32] <R2E4> I just aquired a BP cnc series 1 R2E4
[11:11:43] <R2E4> eBOSS 9
[11:12:25] <R2E4> The iso from the site....IS that the live CD?
[11:12:29] <skunkworks> http://www.linuxcnc.org/index.php/english/download
[11:12:30] <r00t4rd3d> ya
[11:13:06] <skunkworks> R2E4: I don't know my BP's - is that servo or stepper?
[11:13:16] <R2E4> servo's
[11:13:24] <skunkworks> nice - what are your plans?
[11:13:52] <R2E4> well, sell the house, change girdfriends and build a lotus 7.
[11:14:08] <R2E4> hehe...
[11:14:31] <r00t4rd3d> whats a lotus 7?
[11:14:56] <R2E4> Going to strip the cab, use linuxcnc with the mesa cards I think. I need the error correcting feedback. HAve a 5,000 part job coming up I dont want to miss out on.
[11:15:05] <Jymmm> r00t4rd3d: a car
[11:15:08] <r00t4rd3d> oh
[11:15:40] <Jymmm> r00t4rd3d: For the seriously NOT well endowed
[11:15:42] <R2E4> http://super7cars.ca/
[11:16:17] <R2E4> Maybe keep the amps if they are working.
[11:16:19] <rizo> pcw_home, i am using bldc cfg=qi settings. I checked the bldc.comp and there is no such input.
[11:16:51] <rizo> ...to change the commutation angle.
[11:18:21] <R2E4> Will it use a standard post proc? I allready have my CAM and want to make sure I wil beable to use it.
[11:19:40] <skunkworks> R2E4: great - mesa is awesome
[11:22:34] <Tom_itx> mesa is so good it should be illegal
[11:24:09] <cpresser> mesa cured my cancer
[11:24:40] <Jymmm> mesa gave me cancer and 3 STD's
[11:25:40] <cpresser> you need to clean the contacts first bevor inserting the card, Jymmm
[11:26:09] <R2E4> Their slogan should be
[11:26:18] <R2E4> "don't MESA with me!!!"
[11:26:48] <Jymmm> cpresser: Hey now, didn't they teach not to have unprotected mesa insertion
[11:28:23] <r00t4rd3d> http://i.imgur.com/6sv7EO7.jpg
[11:28:26] <r00t4rd3d> thats cool
[11:29:47] <R2E4> MESA with me and I will MESA you up!!!
[11:30:56] <R2E4> Thats a cool table. Did you make it?
[11:31:21] <r00t4rd3d> no
[11:32:32] <r00t4rd3d> I could make one though
[11:32:59] <r00t4rd3d> if i had a shit ton of scrap steel and a powered bandsaw
[11:33:18] <r00t4rd3d> metal bandsaw
[11:38:30] <cncbasher> R2E4:gnipsel.com/linuxcnc/configs/index.html
[11:39:09] <cncbasher> R2E4:see 7i77 config
[11:40:57] <JesusAlos> hi
[11:44:24] <pcw_home> rizo bldc.N.drive-offset maybe
[11:44:26] <pcw_home> does the QI mode move the carriage at startup? (it should)
[11:45:16] <R2E4> ah cool.
[11:47:05] <rizo> pcw_home, there is no such input
[11:48:27] <rizo> maybe i should use angle and value and feed the crafe fith ofset?
[11:48:40] <rizo> maybe i should use angle and value and feed the crake with offset?
[11:49:42] <pcw_home> I copied that from the manual...
[11:51:24] <pcw_home> thatres also bldc.N.lead-angle (default 90 is probably correct for your drives)
[11:51:42] <pcw_home> s/thatres/theres/
[11:51:53] <rizo> i see... thank you
[11:52:05] <rizo> yes, i think 90 is ok
[11:53:35] <pcw_home> to get qi mode to work the motor needs to do a homing move at startup (initiated by rising edge of bldc.N.init)
[11:54:52] <rizo> i have this and it works fine
[11:54:56] <pcw_home> bldc.N.initvalue must be set to somthing reasonable for this to happen
[11:56:08] <pcw_home> then there mus be some offset to tell BLDC the index offset from rotor position (bldc.N.drive-offset i think)
[11:56:49] <pcw_home> well s/rotor/carriage/
[12:06:30] <IchGuckLive> hi all B)
[12:16:43] <pcw_home> Damn Daisey got the vacuum cleaner cord _again_
[12:23:08] <IchGuckLive> Daisey Duck does a clean up her self ?
[12:29:20] <pcw_home> Daisey rabbit destroys the vaccum cleaner cord if I get distracted (like with IRC) when vaccuming the excercise pen
[12:30:29] <IchGuckLive> LOL i found this morning rabbit footprints in the snow around the house maybe not enoph food in the forast as it is now 9weeks on snow
[12:33:09] <pcw_home> No wild rabbits around town (brush rabbits and jack rabbits (really hares) in the hills though)
[12:38:58] <IchGuckLive> pcw_home: what are ack rabbits
[12:39:10] <IchGuckLive> jack i cant find a translation
[12:40:30] <pcw_home> http://en.wikipedia.org/wiki/Black-tailed_jackrabbit is what we have around here
[12:41:14] <IchGuckLive> ah i see lng ears
[12:45:05] <IchGuckLive> B) O.O and the oscar goes 2 a big event to come !
[12:45:28] <IchGuckLive> no milling oscar the people that mantain the stuff are off !
[12:49:28] <R2E4> latency test: servo thread 260711 base thread 227554 are thes good enough?
[12:52:59] <JT-Shop> good enough for?
[12:53:03] <IchGuckLive> R2E4: shit
[12:53:12] <IchGuckLive> SMI
[12:53:27] <IchGuckLive> did you reset
[12:53:42] <IchGuckLive> and look for a jump every 15sec
[12:55:14] <IchGuckLive> R2E4: ?
[12:55:46] <ReadError> holy fail
[12:55:54] <IchGuckLive> this also sems to be on a livecd not a full instalation on this numbers
[12:56:28] <IchGuckLive> if never seen sutch high numbers on a realtime
[12:56:31] <R2E4> ah,, I se it is suppose to be under 100,000
[12:56:32] <R2E4> hehe
[12:56:38] <R2E4> not good.
[12:56:46] <IchGuckLive> what pc is it
[12:56:53] <IchGuckLive> mainboard
[12:57:10] <JT-Shop> under 10,000 is great
[12:57:22] <R2E4> IBM Lenova brick. 1.8 ghz 2 core 2 gig ram
[12:57:38] <R2E4> let me check mobo.
[12:57:41] <IchGuckLive> so did you get the SMI
[12:57:56] <R2E4> I haveanoither Ic an check.
[12:58:16] <IchGuckLive> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?FixingSMIIssues
[12:58:33] <IchGuckLive> ibm has always SMI as i use A50
[12:59:03] <IchGuckLive> R2E4: where are you from USA Europ
[13:00:04] <R2E4> Canada
[13:00:34] <IchGuckLive> i use ibm mashines on all my 120+ mashines
[13:01:31] <IchGuckLive> im in germany
[13:01:43] <IchGuckLive> its late here !
[13:01:54] <R2E4> So how do I turn of the SMI?
[13:02:03] <IchGuckLive> see the linnk
[13:02:18] <IchGuckLive> are you on lucid 10.04
[13:04:35] <IchGuckLive> type -> cat /etc/*release <- in a terminal please
[13:05:21] <IchGuckLive> but i guess you got the latest livecd and so you are on 2.5.0
[13:06:28] <IchGuckLive> JT-Shop: im off get him more help !
[13:06:47] <IchGuckLive> By folks :D
[13:06:56] <R2E4> yeah I got the latest
[13:18:08] <R2E4> Will an AMD64 work ok?
[13:20:02] <L84Supper> AMD64 is fine
[13:25:54] <R2E4> much easier to change copmputers than recompile the kernel.
[13:33:06] <R2E4> servo thread 31761 base thread 138673 thats much better huh?
[13:58:02] <pcw_home> better but still pretty poor for sofware s stepping (say about 4 KHz max)
[13:58:04] <pcw_home> so 120 RPM on a gecko (10 usteps) 600 RPM on a 1/2 step drive
[14:27:30] <Tom_itx> anybody know when andy is due back?
[14:27:59] <Tecan> http://openartisthq.org/ dam fine distro
[14:28:17] <Tecan> great for vm
[15:03:58] <R2E4> After its installed, should I do all the updates?
[15:04:32] <Tom_itx> of course
[15:05:01] <pcw_home> no kernel updates though...
[15:10:03] <R2E4> 166 packages
[15:28:39] <R2E4> IT asks to restart after updates? Whats that....I thought onlywindows did that....hehe
[15:54:45] <r00t4rd3d> anyone watch the nascar race? They crashed in the end and a whole engine went through the fence into the crowd
[16:02:20] <Tom_itx> yeah yeah
[16:03:28] <Tom_itx> had that been an indy car the guy would have no legs now
[16:18:03] <DJ9DJ> gn8
[16:54:21] <AR_> lol this material that i found laying around didnt mill as nicely as i wanted it to
[16:54:22] <AR_> http://i.imgur.com/DCRzqpE.jpg
[16:55:07] <ReadError> atleast you cutting!
[16:55:14] <AR_> yea
[16:55:15] <ReadError> i moved my Y axis today on my new machine
[16:55:29] <AR_> lol
[16:55:53] <ReadError> ive had to go in to work every day this week
[16:55:57] <AR_> well it was supposed to be a limit switch mount
[16:55:58] <AR_> http://i.imgur.com/eH5sbSl.jpg
[16:56:01] <ReadError> would have been much faster if i worked at home ;/
[16:56:19] <ReadError> what material is that?
[16:56:20] <AR_> you can see where there were supposed to be two 'posts' that fit into the holes
[16:56:21] <AR_> http://i.imgur.com/v7E5NIW.jpg
[16:56:26] <AR_> i dont know lol
[16:56:34] <AR_> it's like some composite crap
[16:56:49] <ReadError> you know what cuts really nice?
[16:56:51] <ReadError> HDPE
[16:57:09] <ReadError> delrin too
[16:57:13] <ReadError> but its expensive
[16:57:20] <AR_> yeah
[16:57:53] <AR_> the surfaces got nice and smooth
[16:57:57] <ReadError> you drew any pictures?
[16:57:58] <AR_> it just ripped off those posts
[16:58:12] <AR_> lol not yet
[16:58:16] <AR_> i was going to
[17:31:07] <r00t4rd3d> looks like your machine is all over the place
[17:31:29] <ReadError> did you test for backlash and all?
[17:31:34] <r00t4rd3d> lol
[17:31:47] <r00t4rd3d> whats your stepover?
[17:31:50] <ReadError> that would be some hella backlash ;)
[17:32:57] <r00t4rd3d> he must have some numbers off in his setup or something
[17:33:43] <r00t4rd3d> or a .5 step over
[17:34:13] <r00t4rd3d> garbageCAM
[17:35:45] <ReadError> what cam you using AR_ ?
[17:35:56] <r00t4rd3d> i think master
[17:35:56] <ReadError> you need to step up to some real cam software r00t4rd3d :)
[17:36:38] <r00t4rd3d> i just just add the link to the topic
[17:37:29] <r00t4rd3d> AR_, how computer literate are you?
[17:37:39] <ReadError> add link to topic ?
[17:37:49] <r00t4rd3d> lol
[17:40:32] <Tom_itx> ReadError, what do you use?
[17:45:03] <ReadError> visualmill or hsmxpress
[17:45:10] <ReadError> hsmxpress is really nice for being free
[17:46:06] <Tom_itx> i wish my lathe package displayed rapid moves better
[17:46:14] <Tom_itx> i'm not sure if i trust what it tells me
[17:46:26] <Tom_itx> the mill does
[18:04:25] <Jymmm> Tom_itx: "No, size doesn't matter", "I don't mind you going out with your friends on Valentines Day"
[18:08:19] <AR_> <ReadError> that would be some hella backlash ;)
[18:08:19] <AR_> <r00t4rd3d> he must have some numbers off in his setup or something
[18:08:21] <AR_> why do you say that
[18:08:28] <Jymmm> Tom_itx: "No, I'm not mad"
[18:09:03] <Jymmm> Tom_itx: and the most famous one of all "Nothings wrong"
[18:09:22] <Jymmm> "Nothing's wrong, I'm fine"
[18:10:40] <ReadError> "I dont care how much money you make"
[18:11:28] <AR_> and yes i am using mastercam
[18:12:20] <AR_> the reason there is not nice pocket edge is because i was using a facing toolpath that went past the part edge
[18:13:21] <ReadError> also the direction you cut makes a big difference on some materials
[18:13:47] <AR_> yeah
[18:14:07] <AR_> this was just a zigzag facing path and contour around the 'posts'
[18:14:47] <AR_> the flat face actually looks pretty good in person
[18:15:01] <AR_> but this is a very weird material
[18:15:15] <Jymmm> jello?
[18:15:17] <r00t4rd3d> http://i.imgur.com/Oa3Jznk.jpg
[18:19:45] <Jymmm> r00t4rd3d: context?
[18:19:58] <Jymmm> (other than nascar)
[18:45:50] <r00t4rd3d> just happen today
[18:46:35] <r00t4rd3d> 11 people in the stands got messed up
[18:46:58] <r00t4rd3d> 2 critically i guess
[18:47:36] <Jymmm> ah
[18:47:53] <t12> anyone every use a die grinder as a lathe toolpost grinder?

[19:23:49] <DaViruz> what's up with the cheap ballscrew selles on ebay only giving you the total length, not the travel length or even the means to calculate the travel length
[19:32:55] <pcw_home> because it looks bad?
[20:16:58] <andypugh> t12: sort-of. I used a dremel-a-like. I broke it.
[20:53:00] <ReadError> what does the trimpot on a g540 actually do
[20:56:40] <andypugh> ReadError: I think it sets the mid-band resonance filter

[22:11:52] <andypugh> R2E4: Not great. Are you software-stepping?
[22:12:34] <Tom_itx> hi andypugh
[22:15:01] <Tom_itx> andypugh, i've got a couple files you can look at when you get a chance
[22:16:28] <skunkworks> I think r2e4 is going with mesa - so those numbers if consistant will probably be ok...
[22:26:11] <andypugh> Tom_itx: Just got back from holiday and caught up with emails. Now its 4am. Tomorrow would be better.
[22:28:00] <Tom_itx> that's fine just gimme a holler
[22:28:32] <Tom_itx> i did get something i think you can work with
[22:29:15] <Tom_itx> just need you do do a dry run on them though to be certain
[22:59:59] <JesusAlos> Pncconf wizard, only modific the .ini and .hal file?
