[00:00:07] <Valen> (doesn't bother the current mill, it uses glass scales)
[00:01:41] <Theta9> dang allelectronics is finally out of those big ass 24v scooter motors
[00:02:06] <Theta9> Valen, why not drill/tap a hole in the shaft?
[00:02:15] <Valen> to what end?
[00:02:25] <Theta9> attach the encoder?
[00:02:43] <Valen> the end of the shaft is inside the ballscrew
[00:02:53] <Valen> the shaft is like 8mm long
[00:04:19] <Valen> the shaft also doesn't come out the back end
[00:04:40] <Theta9> that's what i meant... attach to the bag with a hole in the shaft
[00:04:46] <Theta9> s/bag/back/
[00:05:01] <Valen> the shaft is buried inside the motor
[00:05:19] <Theta9> dang

[00:05:38] <Valen> is what we have
[00:06:40] <Theta9> that thing is huge!
[00:07:02] <Theta9> mine look very similar in style, minus the mounting bracket, and about 3/4 the size
[00:09:12] <Valen> it is pretty epic lol
[00:10:48] <Valen> andypugh: so what do you think, geckos or mesa with KL23-130-60 (NEMA23 from http://www.kelinginc.net/ServoMotors.html
[00:10:54] <Valen> or Theta9 for that matter
[00:10:59] <Valen> or anybody else
[00:12:22] -!- logger[mah] has quit [Remote host closed the connection]
[00:12:27] <andypugh> Does the Keling package come in cheaper for the Geckos?
[00:12:28] -!- logger[mah]_ [logger[mah]_!~loggermah@ns2.mah.priv.at] has joined #linuxcnc
[00:12:48] <Valen> $1200 for a ready to run setup
[00:13:15] <Valen> http://www.kelinginc.net/CNC23ServoMotorPackage.html
[00:13:20] <andypugh> I don't really like step/dir servos, But I am sure that is just an aesthetic thing
[00:13:21] <L84Supper> Valen: do you really order from the midwest US to Australia?
[00:13:21] <Valen> kit 2
[00:13:32] <Valen> everything comes from overseas
[00:13:39] <Valen> australia makes nothing
[00:13:39] <L84Supper> keling has changed names
[00:13:58] <Valen> we also don't like step dir servos
[00:14:16] <L84Supper> he changed to http://www.automationtechnologiesinc.com/
[00:14:22] <L84Supper> same building
[00:14:23] <andypugh> Yeah, Valen, have you see the (much better) new Keling website?
[00:14:36] <Valen> as of 6 seconds ago yes
[00:15:39] <andypugh> http://www.automationtechnologiesinc.com/products-page/ac-servo-motors/ac-brushless-servo-motor-and-driver makes the DMM look like a good price
[00:15:41] <L84Supper> China --> Chicago --> Melbourne.... I'm just trying to see if I can't find you a shortcut
[00:15:51] <Valen> sydney but close enough
[00:16:09] <L84Supper> ah ok, I thought you were down south
[00:16:12] <Valen> I do have one group who buys chinese motors close by, but mobile stuff (drill motors)
[00:16:32] <Valen> don't get me wrong that dmm is a good price
[00:16:52] <Valen> for the second mill (steel milling 4/5 axis machine) i think I'll be going that way
[00:17:04] <andypugh> I want someone to guinea-pig them. And someone too far away to hit me seems ideal.
[00:17:10] <Valen> rofl
[00:17:27] <Valen> It wouldn't bother me too much to split the encoder feeds back to EMC as well as the servo drive
[00:18:12] <Valen> run the servo as a velocity controller
[00:20:04] <L84Supper> http://www.motionking.com/index.htm is where I think they come from
[00:20:41] <L84Supper> I'm going to visit them in a few weeks
[00:23:19] <L84Supper> the smaller steppers anyway
[00:23:58] <Valen> friggin awesome btw http://www.youtube.com/watch?feature=player_embedded&v=ffEYqGGYXRk
[00:24:16] <Valen> 2 guys in a helicopter rescue a RC plane from a tree
[00:24:28] <Valen> note a fair bit of language
[00:25:12] <Valen> L84Supper: i don't see any brushed servo motors there
[00:26:24] <L84Supper> http://www.stepper-dc-motor.com/products.html
[00:27:14] <L84Supper> Valen: DC brushed servo?
[00:27:35] <Valen> cheaper I was thinking

[00:33:17] <L84Supper> scooter and wheelchair motors just keep coming up all the time
[00:34:00] <Valen> they are all generally single shaft though
[00:35:04] <L84Supper> http://www.automationtechnologiesinc.com/products-page/kl-stepper-drivers I haven't tried these yet. Low priced
[00:37:16] <andypugh> Valen, did you see: http://www.automationtechnologiesinc.com/products-page/servo-nema34-kits/4-axis-nema34-850-oz-in-72v20a-psu-g320x-gecko-driver
[00:37:44] <Valen> yeah i looked at that one
[00:38:00] <Valen> but the motors are heavier, and the 20A gecko cant hit the peak torque anyway
[00:38:04] <L84Supper> the guy has nearly no overhead
[00:38:24] <andypugh> Nema 42 steppers!??
[00:39:08] <L84Supper> just ~5k sq ft of warehouse, no showroom
[00:41:06] <L84Supper> http://www.automationtechnologiesinc.com/career-opportunities he's hiring

[00:56:58] <teb_> good evening
[00:58:04] -!- Tom_garage [Tom_garage!~Tl@unaffiliated/toml/x-013812] has joined #linuxcnc
[00:58:21] <teb_> being linuxcnc free and open, is there any "kind of library" with parts designs to make with using linuxcnc?
[00:58:51] <jdh> gcode is somewhat machine specific
[00:59:46] <teb_> that's the problem I'm having, this cnc machine I use at work uses very old files and I'd like to implement some new designs and make different parts
[01:00:19] <teb_> but this old files implement some words that are "propietary" to the controller software
[01:00:34] -!- ve7it has quit [Remote host closed the connection]
[01:00:46] <jdh> reject proprietary opression and embrace the freedom that is LinuxCNC
[01:01:18] <jdh> (did that sound convincing)
[01:01:40] <L84Supper> doesn't heeks generate g-code?
[01:02:05] <teb_> I would like to use linuxCNC at home to design parts and make the G-code and tests, but I can't figure a way of getting it to work with the cnc machine using it's propietary controller software
[01:02:08] -!- rob_h has quit [Ping timeout: 252 seconds]
[01:02:19] <jdh> what control does it use?
[01:02:31] <teb_> it's a brazilian one
[01:02:37] <teb_> i've got the manual right here lemme check
[01:02:45] <L84Supper> custom g-code?
[01:03:18] <teb_> I'd actually like to get free diesigns (maybe CAD files) and get them to linuxcnc, drive tests and then machine them
[01:03:31] <teb_> Numeric Controller MCS SX570
[01:03:38] <L84Supper> teb_, there are plenty of files around for free
[01:04:32] <L84Supper> teb_, you can design your own simple parts without too much work
[01:05:34] <teb_> I'm a total newb to everything related to CNC, a friend of mine has a factory and thanks to visiting him I got to learn some stuff.. Then I applied for a CNC Lathe Operation Job and I just got the job lol
[01:05:37] <teb_> Now I'm im trouble
[01:05:49] <teb_> haha AND very interested in learning
[01:06:06] <L84Supper> https://sites.google.com/site/heekscad/Details
[01:09:17] <teb_> thanks L8
[01:11:13] <teb_> L84Supper, do you know of a linux alternative for heekscad?
[01:12:19] <L84Supper> teb_, another open linux CAD application?
[01:12:35] <teb_> I just found a .exe link for the latest version of heekscad
[01:12:51] <L84Supper> there are linux packages
[01:12:57] <teb_> oh, thanks
[01:12:58] <L84Supper> what are you running?
[01:13:02] <teb_> Debian Squeeze
[01:14:12] <L84Supper> there's an Ubuntu package
[01:14:37] <L84Supper> can you compile from source? or do you need a package?
[01:14:53] <teb_> No problem with source compiling

[01:17:24] <teb_> So what would be the best approach for starters design & cnc-testing of solid parts in the lathe machine?
[01:18:48] <mutilator> anyone etch glass? trying to find a good bit, all these diamond coated things are crap
[01:18:59] <mutilator> https://dl.dropbox.com/u/24715738/IMG_20121031_211029.jpg
[01:21:22] sliptonic is now known as sliptonic_away
[01:22:05] <teb_> L84Supper, do you know what steps should I follow to turn my cad design into a lathe-machined ZX toolpath? Is my resulting G-code going to be supported by the SX570 controller?
[01:23:46] <L84Supper> heh it's all in Portuguese!
[01:24:01] sliptonic_away is now known as sliptonic
[01:24:39] <teb_> Yes, and I speak spanish
[01:25:10] <teb_> I will have to become a garoto very soon
[01:25:21] <L84Supper> i don't know anything about that controller
[01:25:35] <teb_> Maybe I should try find an emulator
[01:26:46] <L84Supper> you can design parts and create g-code with heeks and then run it in simulation in Linuxcnc
[01:27:22] <teb_> Ah, that will be enough for starting :) thank ou L8
[01:27:55] <L84Supper> or even create some g-code manually and run it through simulation
[01:41:19] <Valen> L84Supper: where are you anyway?

[15:34:16] <Mike24> Hello ! I'm struggling to configure a servo-based spindle with Mesa's 5i25 and 7i77 boards. Motor maximum velocity is greyed out in pncconf (100rpm) and I can't find how to modify it. The encoder output is good. Should I add "loadrt scale etc" (found in the manual) as with a vfd ? Thank you !

[15:49:28] <JesusAlos> i need to make a bar similar to axis speed control.
[15:50:15] <JesusAlos> but this bar must control a pause time between each change of direction in a two-axis machine
[15:51:28] <JesusAlos> this pause should not be within gcode
[15:55:44] <jdh> where should it be?
[15:57:18] <JesusAlos> i don't Know
[15:57:57] <JesusAlos> i want to say that ths pause is must be out gcode, because the user need change online it
[15:58:55] <skunkworks> hmm- it would be a lot easier in gcode.. You could pre-proccess the file into axs.. Otherwise - maybe exact stop mode - if 'in position' is activated at each end point - you could maybe use adaptive feed rate and set it to 0... (lots of ifs...)
[15:59:25] <skunkworks> (set it to 0 for an amount of time)
[16:01:08] <jdh> pretty much every time I have used a delay in any type of code, I have always been eventually disappointed.
[16:01:39] <JesusAlos> why?
[16:02:11] <roh> JesusAlos: what is the pause for?
[16:02:18] <jdh> things that need delays don't seem to need the same delay each time.
[16:03:59] <jdh> can you do an m66 for any hal pin?
[16:04:54] <JesusAlos> EPS foam when cutting to a high linear velocity, the hot wire is late and i must to wait for it recover before the change of direction
[16:05:26] <jdh> doesn't that depend on the speed of the move, the density of the foam, the cleanliness of the wire, the current through the wire, etc?
[16:05:47] <roh> hm.. m66 looks nice.. i was using m0 now and was thinking of adding some 'continue' button on the machine
[16:06:16] <Jymmm> JesusAlos: how long is the hotwire?
[16:06:33] -!- cncbasher__ [cncbasher__!~quassel@cpc15-hart9-2-0-cust101.11-3.cable.virginmedia.com] has joined #linuxcnc
[16:07:06] <jdh> you could pump a pwm through a pin with the duty cycle being the variable delay time, then preprocess the code to m66 low then high
[16:07:10] <JesusAlos> about 1500mm
[16:07:20] <JesusAlos> http://imagebin.org/234201
[16:07:43] <JesusAlos> is a software to a manufacturer machines
[16:08:26] <Jymmm> JesusAlos: How much of a delay are you needing?
[16:08:34] <Jymmm> to catch up
[16:08:45] <Jymmm> on avg
[16:08:49] <JesusAlos> about 4 seconds
[16:09:29] <roh> wouldnt it be nicer to wait for the wire to be straigtened again?
[16:09:34] <roh> instead of using time
[16:09:42] <JesusAlos> m66 and m0 involves alteration of gcode
[16:09:46] <Jymmm> JesusAlos: OUCH... I think you need to look at increasing your temp controller. Unless you are doing complex cuts, that's huge
[16:09:52] <roh> does the machine measure the tension of the wire?
[16:10:14] <skunkworks> roh's idea seems like a better solution...
[16:10:39] <Jymmm> hot wires are usually spring loaded
[16:11:02] <roh> i mean.. the sw knows the length of the wire if straight.. could one measure the lenght change under load?
[16:11:12] <JesusAlos> the wire have about 180N of tension
[16:11:19] <roh> i guess the head makes them longer as well?
[16:11:20] <JesusAlos> with springs
[16:11:28] <roh> irgh. s/head/heat/g
[16:11:31] <Jymmm> at 60" the hotwire thermally expands on it's own from 4 to 6 "
[16:12:04] <roh> whow. thats a lot
[16:12:07] <Jymmm> Nice idea, just not practical imo.
[16:12:33] <Jymmm> roh: Well, the working temp of NiChrome is 1800F =)
[16:12:52] <JesusAlos> about 90ºC
[16:13:24] -!- cncbasher_ has quit [Quit: time to make some more scrap]
[16:13:40] <Jymmm> JesusAlos: seriously?! for EPS you need to increase that by at 1.5x
[16:14:01] <JesusAlos> the problem is that you raise the temperature of the wire
[16:14:44] <Jymmm> JesusAlos: Yes, but increase the temp AND constant controlled cnc movement will make for clean cuts
[16:15:09] <Jymmm> JesusAlos: If this was being cut by hand, I understand the lower temps
[16:15:12] <JesusAlos> burn more in the outer faces of the block that in the interior due to
[16:15:38] <Jymmm> JesusAlos: what gauge?
[16:15:48] <JesusAlos> the difference in indoor-outdoor humidity
[16:16:06] <Jymmm> JesusAlos: Well, heat the warehouse =)
[16:17:14] <JesusAlos> note that cut block industrially
[16:17:32] <JesusAlos> about 1500x1500mm of section
[16:17:49] <JesusAlos> and 2500mm of long
[16:18:13] <JesusAlos> speak of pantographs
[16:18:22] <Jymmm> But look at what that 4s delay is doing.... It's holding the wire still at the outside edges, while he middle is still catching up.
[16:18:53] <JesusAlos> for all this, we need pause stop
[16:19:57] <Jymmm> I think you need to look at 1) the hotwire gauge/type and 2) your voltage/amperage, 3) humidity compensation
[16:20:15] <JesusAlos> believe me. It is the best way to work with these sizes
[16:20:33] <Jymmm> what gauge hotwire?
[16:21:03] <JesusAlos> about 0,5mm i think
[16:22:06] <Jymmm> JesusAlos: 30ga at 60"
[16:22:14] <JesusAlos> Jymmm: have much experience in cutting EPS. The best solution is the pause time
[16:22:30] <JesusAlos> What?
[16:22:42] <JesusAlos> 30ga?
[16:22:46] <Jymmm> JesusAlos: Is your controller fixed output voltage?
[16:23:07] <JesusAlos> no
[16:23:11] <JesusAlos> is variable
[16:25:14] <JesusAlos> i need is change in emc2. Not change the way companies operate
[16:25:19] <Jymmm> I'd try a larger gauge hotwire and playing with controller settings
[16:25:51] <Jymmm> intentionally adding a pause/delay is never a good thing in cnc
[16:26:22] <JesusAlos> but, believe me, is necesary in this case
[16:26:43] <Jymmm> JesusAlos: why the precision for such a small hotwire?
[16:27:57] <JesusAlos> is pfor material utilization
[16:28:41] <JesusAlos> is possible the tread may be thicker
[16:28:42] -!- ve7it has quit [Remote host closed the connection]
[16:29:32] <Jymmm> JesusAlos: tread?
[16:29:57] <JesusAlos> sorry. Wire
[16:30:23] <JesusAlos> is there no way to implement the pause?
[16:31:04] <Jymmm> JesusAlos: Ok, yeah please do try a thicker wire. I think you'll get better results long run, but you'll have to play around with the temp controller to find the sweet spot.
[16:32:19] <Jymmm> JesusAlos: and as you say compensate for humidity and room temperature.
[16:32:53] <JesusAlos> Jymmm: it's no easy for the operator machine
[16:33:18] <JesusAlos> so. the manufacturers machine put stop pause in her software control
[16:33:49] <JesusAlos> and for the moment i no have solution for my machines
[16:34:22] <Jymmm> JesusAlos: I've made hotwires for EPS that are perfect for hand carving sculptures, yet crap for other foams. and even different grades of EPS.
[16:34:54] <Jymmm> JesusAlos: I kind of customize the cutter to the material
[16:36:14] <JesusAlos> Please. I need some reference to do this function in emc2
[16:36:38] <Jymmm> JesusAlos: All I'm trying to say is inducing a delay isn't the right solution long term, it's just a hack imo.
[16:36:55] <hdokes|werkin> Hey Gents, I have a bridgeport series 1 manually operating mill that I would like to retrofit for cnc... is there a source for information on how to size the servo motors for such?
[16:36:55] hdokes|werkin is now known as hdokes
[16:37:38] <Jymmm> JesusAlos: Teach the operator, or get a fancier heat controller to compensate.
[16:37:58] <JesusAlos> Jimmm: I understand your position. But my clients want it
[16:38:03] <Jymmm> JesusAlos: What are you usign for temp control?
[16:38:57] <Jymmm> JesusAlos: a variac?
[16:39:04] <JesusAlos> yes
[16:39:10] <JesusAlos> variac
[16:39:34] <Jymmm> so it's AC on the hotwire?
[16:39:45] <JesusAlos> yes
[16:39:49] <JesusAlos> AC voltage
[16:40:14] <Jymmm> 50Hz AC on a 60" wire == it hums (vibrates)

[16:43:29] <JesusAlos> what you mean?
[16:45:09] <Jymmm> JesusAlos: Will your client be willing to spend the money to try a digitally controlled, environment compensating temperature controller?
[16:45:37] <JesusAlos> is possible
[16:45:43] <Jymmm> $300 - $1000 USD
[16:45:45] <JesusAlos> if i say
[16:45:51] <JesusAlos> is possible
[16:46:15] <JesusAlos> yes i think
[16:47:19] <Jymmm> ok, you might take a look at that for long term solution. Also, I don't think a variac provides isolation to the hotwire like a normal transformer does.
[16:48:26] <Jymmm> You might play with DC instead of AC controller, and see what results you get.

[19:16:28] <jthornton> alex_joni, want to try out my latest time sink?
[19:16:47] <mutilator> i just was looking to anyone with experience for their thoughts
[19:17:44] <jdh> mutilated: I nominated you to buy multiple bits and arrange a study to determine best tool usage.
[19:18:06] <jdh> how about a spring loaded diamond bit?

[19:19:17] <mutilator> if i wanted to do that i wouldnt have asked and just went ahead
[19:19:21] <mutilator> thats what i was trying to avoid

[19:19:48] <mutilator> if it were new frontier i would be
[19:20:14] <L84Supper> mutilator, we used to use diamond bits that worked really well
[19:20:17] <mutilator> once we discover kryptonite i'll be the first to determine how to mill it
[19:20:20] <mutilator> just for you jdh

[19:20:49] <L84Supper> mutilator, are you trying to avoid chemical etching?
[19:21:17] <mutilator> yea
[19:21:44] hdokes|werkin is now known as hdokes
[19:21:48] <mutilator> not going to be full production line stuff i just want to be able to do it once in a while
[19:22:08] <andypugh> mutilator: Etching glass normally requires HF. You don't want to.
[19:22:30] <jdh> chemical etching is messy. pcb or glass. cnc rotary etching is such a wonderful idea.
[19:22:36] <mutilator> yea
[19:22:44] <mutilator> well i have plenty of spills from pcb etching
[19:22:51] <mutilator> FeCl doesnt come out of anything
[19:22:57] <jdh> heh
[19:23:06] <andypugh> At least FeCl3 doesn't soak into your skin and dissolve your bones.
[19:23:15] <mutilator> this is true, which is why i chose it
[19:23:42] <andypugh> Rubber mask and grit-blast is one way
[19:24:19] <jdh> we have HF as a byproduct here... we do 'sense and flee' training.
[19:24:33] <L84Supper> mutilator: photopolymer and a DLP to create the mask
[19:25:05] <andypugh> Reprap then grit-blast?
[19:25:52] <L84Supper> or photopolymer applied with a silkscreen
[19:26:01] <L84Supper> then grit blast
[19:27:49] <andypugh> Photopolymer _and_ silkscreen seems a bit excessive
[19:28:23] <L84Supper> cnc cut a steel mask and then blast
[19:28:59] <L84Supper> it depends on if you want a lot of the same pattern or all unique

[21:24:09] <JesusAlos> andypugh: i try it. it run ok
[21:25:01] <andypugh> JesusAlos: I don't know about HeeksCNC. Possibly. dxf-to-gcode is an option, or gcodetools in Inkscape
[21:30:14] <JesusAlos> dxf2gcode is a 3 axis
[21:30:27] <JesusAlos> don't run in a 2 axis machine
[21:31:02] <andypugh> That seems odd, as DXF is 2D.
[21:32:01] <JesusAlos> yes but there are a Z parameters

[22:51:23] -!- rob_h has quit [Quit: Leaving]
[22:51:52] <andypugh> Or, you can indeed have a separate INI in the same folder. Of you look inside sim->axis sample configs you will find that there are 4 or 5 machines all sharing config files.
[22:53:04] <Aero-Tec> cool
[22:53:06] <Aero-Tec> thanks
[22:54:42] <andypugh> Basically the INI defines a "machine" and appears as a choice in the config picker. Any INI can reference as many HAL files as it wants to.
[22:55:45] <JT-Shop> and HAL files can call other HAL files
[22:56:53] <andypugh> can they?

[23:19:59] <Aero-Tec> could the problem be I am running to new a version?
[23:20:24] <JT-Shop> if your having a problem with Ubuntu yes that could be it
[23:20:31] <Aero-Tec> I think I am running the 10 version on the lathe and that is the one with 250,000 jitter
[23:20:44] <Aero-Tec> no problems that I know of
[23:20:49] <Aero-Tec> other then the jitter
[23:21:00] <Aero-Tec> every thing else is 100%
[23:21:02] <JT-Shop> the key is "that I know of"
[23:21:15] <Aero-Tec> the mill is running 8
[23:21:30] <Aero-Tec> it has 11420 for jitter
[23:21:57] <Aero-Tec> I would like to change the network name of the mill and can no
[23:22:02] <andypugh> Ah, yes, that is almost certainly the difference.
[23:22:20] <Aero-Tec> the lathe was no problem as the gui made it easy
[23:22:33] <andypugh> You may have different drivers with the different systems, for a start.
[23:23:31] <Aero-Tec> so what is the best way to install 8 on the 10 unit?

[23:25:49] <Aero-Tec> I have a working 10
[23:25:58] <Aero-Tec> would like to make it 8
[23:26:11] <Aero-Tec> ok
[23:26:16] <Aero-Tec> was there
[23:26:48] <Aero-Tec> have tried some of it, not all
[23:27:14] <Aero-Tec> I know 8 works so would like to do 8 if possible
[23:27:34] <andypugh> But 10 can work fine too.
[23:27:53] <andypugh> Is it possible you did the SMI fix on the 804 version and forgot on the 10?
[23:28:04] <Aero-Tec> I like 10 better
[23:28:17] <Aero-Tec> could be
[23:28:19] <Aero-Tec> will look

[23:28:31] <andypugh> Is the 8,04 running now?
[23:28:51] <andypugh> lsmod will probably show if rtai_smi is loaded

[23:31:51] <andypugh> JT-Shop: Trying to run your Calculator on my Mac I get "RuntimeError: Bad magic number in .pyc file". I don't know if that is to be expected.
[23:32:32] <Aero-Tec> Ismod?
[23:32:39] <Aero-Tec> I am very green
[23:32:57] <Aero-Tec> do I type that into the terminal?
[23:32:58] <cradek> it's incorrect to distribute a pyc. those are not portable.
[23:33:13] <cradek> just delete them
[23:33:17] <Tom_itx> JT-Shop the calc looks better with the scrolling list
[23:33:20] <cradek> they're autogenerated from the py
[23:34:26] <andypugh> There is no .py...

[23:48:42] <Aero-Tec> mill has smi mod
[23:48:54] <andypugh> aha!
[23:49:10] <Aero-Tec> is there any differances from 8 to 10 in installing the smi mod?
[23:49:29] <Aero-Tec> can I just copy the file over?
[23:49:51] <andypugh> the rtapi.conf? I htink so.
[23:49:59] <Aero-Tec> yes
[23:50:10] <Aero-Tec> any way to know for sure?
[23:50:43] <Aero-Tec> would like to kep
[23:50:59] <Aero-Tec> would like to keep 10 if possible
[23:53:50] <Aero-Tec> The above works for installed emc2 - for 'run in place' it is a bit different.
[23:53:55] <Aero-Tec> what is run it place?
[23:54:05] <Aero-Tec> is that running off the CD?
[23:54:11] <Aero-Tec> live disk
[23:54:17] <andypugh> no
[23:54:27] <andypugh> Compiled in it's own directory.
[23:54:39] <Aero-Tec> do I need to worry about run in place?
[23:54:47] <Aero-Tec> ok
[23:55:01] <Aero-Tec> so seeing as I did a live cd install then I should be OK
[23:55:03] <Aero-Tec> right?
[23:55:14] <andypugh> aye
[23:55:39] <Aero-Tec> off to see if the smi mod works
[23:55:57] <Aero-Tec> the jitter jumps real quick
