#emc | Logs for 2010-01-30

[00:05:25] <MarkusBec> MarkusBec is now known as MarkusBec_away
[00:37:59] <andypugh> bevins: <bevins> Hi all
[00:37:59] <andypugh> [00:34] bevins: <bevins> Installed emc2 from live cd and I am trying to find a way to slave my Y and A axis. Setting the pins to Y axis for both axis in stepconf wizard doesn't work. Still only the real Y axis motor turns racking my Gantry
[00:38:00] <andypugh> [00:34] bevins: <bevins> any ideas?
[00:39:37] <andypugh> To answer the question, a bit: A is a rotary axis, if you want an axis parallel to Y then it should be U
[00:40:38] <andypugh> The axes are X,Y,Z,A,B,C,U,V,W where A is rotary around X, and U is linear parallel to X
[00:41:15] <WalterN> is U used for a second turret for example?
[00:41:21] <andypugh> And X is always axis.0, Y is axis.1 and V is axis.7
[00:41:24] <bevins> I have a cnc gantry router with XYZ axis.
[00:41:56] <bevins> Y axis has two motors attached to it. I need both motors to get the same pulses when Y is moving.
[00:42:14] <andypugh> There has been recent discussion on dual motor gantries on the mailing list
[00:42:36] <bevins> I am trying to find that now. searching the archives
[00:42:57] <andypugh> I assume that simply wiring the same output pin to both stepper drivers is no solution?
[00:43:14] <bevins> I just installed emc2 over my Mach3 OS because I got some bizarre activities trying to run Mach3/Winblows
[00:43:58] <bevins> I tried that, in the stepconf wizard and it didn't work despite what some people have said in the forums, it didn't work.
[00:44:58] <Valen> I am unsure but I thought you (somehow) just told it that both axies were "x"?
[00:45:33] <bevins> I stumbled across some docs with the kinectics module or somethng and found myself staring at C code. I quickly departed that setting.
[00:45:50] <andypugh> Aye, gantrykins is part of the puzzle.
[00:46:01] <WalterN> aww... C is fun though :(
[00:46:17] <bevins> I don't understand. Is this not a normal everyday scenario?
[00:46:21] <andypugh> Personally I can't see a reason not to use a nice rigid physical cross-shaft.
[00:46:46] <Valen> bevins, the guy you really want to talk to is SWPadnos,
[00:47:10] <bevins> hehe, what does that stand for?
[00:47:15] <Valen> nfu
[00:47:17] <Valen> nfi
[00:47:18] <bevins> hehe
[00:47:27] <Valen> I think its something to do with his name
[00:47:48] <Valen> I am interested as I'm planning on doing the same with a servo system
[00:48:25] <WalterN> use a ball screw
[00:48:35] <WalterN> if you dont already
[00:48:39] <Valen> I was going to use 2
[00:48:48] <mozmck> I think you can just set both motors as "X" in stepconf like Valen said.
[00:48:50] <bevins> I built this machine and it works great. I am getting 700IPM, and everything works in Mach3 except some windows process screws it all up.
[00:49:12] <Valen> I heard its something like that mozmck
[00:49:17] <mozmck> but you will also have to do something for homing, and I'm not quite sure what.
[00:49:22] <bevins> http://www.youtube.com/watch?v=FadI53SivOg
[00:49:33] <mozmck> I don't think you need gantrykins either.
[00:49:42] <WalterN> Valen: seems like many people use just a regular chunk of all-thread, IMO for something simi nice go with ball screws :)
[00:49:46] <Valen> it'll probably trip home for the axis on either weitch
[00:49:52] <Valen> switch
[00:49:53] <bevins> I tried it and it doesn't work
[00:50:19] <andypugh> Yeah, reading the docs there is some debate about how best to home that arrangement if both sides have their own limit switches, but it should be easy enough to wire it all up in hal simply manually adding some "net" lines
[00:50:26] <bevins> Set pins for A and Y t Y set and direction
[00:50:35] <mozmck> I think you want a switch on each side and you want them to both trip.
[00:50:47] <Valen> mozmck that would be best
[00:51:01] <Valen> http://www.mail-archive.com/emc-users@lists.sourceforge.net/msg18574.html
[00:51:09] <Valen> nice machine
[00:51:13] <andypugh> Steppers can afford to stall on a hard stop, after all.
[00:51:30] <bevins> thanks
[00:51:35] <WalterN> you would lose your place though
[00:51:37] <Valen> My problem is I want to do it with servos
[00:52:30] <bevins> I don't care about homing right now, I just want to get them synced.
[00:52:33] <mozmck> that is a common configuration for gantry router tables. Mine just has one motor so I haven't had to figure out how to set emc up with two yet.
[00:53:11] <andypugh> It's only a style thing, but A shouldn't really be a linear axis. In practical terms it probably doesn't matter.
[00:53:19] <bevins> this one is too big for just one motor to pull the gantry.
[00:54:25] <andypugh> I think that you need to only have one X axis, but direct the position-cmd to two stepgens, and then have those stepgens enabled by the limit switch.
[00:54:34] <bevins> http://www.youtube.com/watch?v=ra4amnO6L8g
[00:54:41] <Valen> pastebin your ini and hal files perhaps?
[00:54:55] <bevins> Its cutting the back of the musicman guitar, the front went haywire....
[00:54:56] <andypugh> Though this is me thinking aloud
[00:55:06] <WalterN> so with the steppers, you would have to take one of them and turn it the other direction
[00:55:19] <WalterN> in that configuration, right?
[00:55:39] <bevins> No, why would you have to do that?
[00:56:01] <WalterN> if you have two motors on either end of the axes
[00:56:01] <bevins> That would send one side of the gantry one way and the other side the other way
[00:56:12] <WalterN> and both are used to move the axes one direction
[00:56:37] <bevins> I have two lead screws on the Y axis
[00:56:47] <WalterN> ah
[00:56:50] <mozmck> if the motors both point in then one has to turn the opposite direction from the other, in relation to the motor itself
[00:56:54] <WalterN> nvm then
[00:56:56] <andypugh> If you paste your hal file to www.pastebin.ca we can have a look. In a matter of minutes you will have several non-functioning and completely different alternatives back :-)
[00:57:12] <bevins> haha,
[00:57:34] <bevins> I have to go find them. and no irc client on that machine but I can fanagle....hang on
[00:57:48] <Valen> sudo apt-get install xchat
[00:57:50] <Valen> ;->
[00:58:07] <bevins> I don't want to insall anything uneccesary on it
[00:58:25] <Valen> its linux, if you dont run it it wont get in the way
[00:58:38] <andypugh> IRC is not unnecessary, and I think that there is a client on the liveCD, actually.
[00:58:39] <Valen> archivist seriously abuses the crap out of his machine while running it
[00:58:54] <bevins> haha
[00:59:07] <Valen> like kernel compiles and mysql compiles and testing, firefox, and irc all running while cutting stuff
[00:59:21] <bevins> STOP!!
[00:59:25] <bevins> no way
[00:59:32] <Valen> yeah
[00:59:39] <Valen> he doesent even have SMP kernel
[00:59:45] <andypugh> Hi Jymmm. Sorry about earlier. On reflection, two nations divided by a common language. We use "getting" diferently,
[00:59:47] <Valen> (ie using multiple CPU's)
[01:00:01] <bevins> are you serious?
[01:00:07] <Valen> yes
[01:00:32] <Valen> the only thing that affects mine is starting openGL windows
[01:00:41] <Valen> and that doesn't actually cause a problem
[01:00:46] <andypugh> EMC isn't intensive, and RTAI takes precedence, so as long as there is enough CPU there to go round, the realtime stuff still happens.
[01:00:54] <bevins> I'll have to try that, but I won't have a piece of cherry mahogany blank on it while doing it, thats for sure.
[01:01:12] <Valen> you should do all that stuff while running latency test
[01:01:43] <Valen> see if theres anything in your hardware thats not going to play nice
[01:02:00] <bevins> let me go get those files....
[01:04:15] <andypugh> <thinking aloud> If you wire the stepgen-enable signals for each motor through an XOR block on the home switches, and the home signal through an AND, does that achieve what is needed?
[01:05:02] <WalterN> bevins: what if you preamp the signal before getting to the controller with a little transistor?
[01:05:37] <andypugh> I am not sure that fan-out is the issue.
[01:05:49] <WalterN> *shrug*
[01:05:55] <bevins_EMC> ok I'm on da machine
[01:06:15] <bevins_EMC> xchat is cool, I remember using it a while back
[01:06:41] <andypugh> Paste your HAL file to pastebin.ca, lets have a look (whilst there are other pastebins, that one I can remember the URL of)
[01:07:23] <bevins_EMC> I didn't do anything with HAL btw, I just ran stepconf
[01:07:48] <andypugh> Yes, but stepconf isn't terribly good with complex configs.
[01:08:23] <bevins_EMC> Then I need to figure out what HAL is...:-)
[01:08:35] <andypugh> I have seen (but not been part of) discussion of renaming it to "BasicConf"
[01:09:06] <andypugh> Look in your /emc2/configs/ folder and you will find where all your machine config data is
[01:10:03] <andypugh> The .ini file describes the parameters such as speeds and leadscrew pitches, and then the hal file connects together all the logic
[01:10:28] <bevins_EMC> in the meanwhil;e http://www.rbevins.com/4X4_Garage is a live cam on my machine, you can pan and tilt it also and watch how the gantry racdks when I try to move Y...:-)
[01:11:20] <andypugh> Whoo! give me VNC access and I can break hardware on a different continent
[01:12:00] <WalterN> heh
[01:12:33] <andypugh> I think that cam has too many drivers :-)
[01:13:03] <andypugh> Was that a power drawbar?
[01:14:06] <andypugh> Can't read the URL from here :-)
[01:14:21] <bevins_EMC> http://pastebin.ca/1771489
[01:14:23] <bevins_EMC> haha
[01:16:54] <bevins_EMC> http://pastebin.ca/1771493 this is the ini
[01:21:17] <andypugh> Ah, I forgot to ask, does the second motor have its own driver?
[01:21:28] <bevins> yes
[01:21:46] <andypugh> Currently on the A pins?
[01:22:19] <bevins> It is set for pins 8 and 9 for A but I configured it to y step and direction in stepconf
[01:22:43] <bevins> So no its not on A it is on Y
[01:25:10] <andypugh> Do you actually have limit switches?
[01:27:29] <Valen> bevins pretty cool on the camera what is it?
[01:29:10] <andypugh> OK, I have been trying to do something too clever with the Hal and doing home switches.
[01:29:53] <andypugh> Which isn't a bad thing.
[01:30:50] <bevins_EMC> yes I do, I have them wired into one input at the moment
[01:31:46] <bevins_EMC> Valen, it is a spectra P&T camera going into a cheap tc card running on a P75/500M Ram
[01:32:09] <bevins_EMC> A small http server spitting serial messages out the com port when you press the move buttons
[01:32:32] <bevins_EMC> Going into a matrix that is actually sending the commands down the coax to the camera
[01:34:09] <andypugh> Very simple mod, changing some signal names, and linking both to the same stepgen output
[01:34:11] <andypugh> http://pastebin.ca/1771508
[01:34:52] <andypugh> I have another version almost ready for when you add limit switches, using XOR and AND logic and seperate stepgens for each motor.
[01:36:38] <andypugh> But can't get much further without limit switch pins to wire to
[01:37:10] <bevins_EMC> Which file do I save it to? The HAL?
[01:37:33] <andypugh> I advocate other people checking my work, that is without reference to a working emc installation
[01:37:43] <bevins_EMC> I only have 4 inputs on my controller I think
[01:37:51] <bevins_EMC> I am using the G540 from Gecko
[01:38:15] <andypugh> Yes, save your old hal somewhere safe, and then put that one in its place
[01:38:25] <bevins_EMC> One pin I am using for e-stop
[01:38:31] <andypugh> Then start emc, and let me know what error message you get
[01:38:45] <bevins_EMC> haha
[01:38:59] <bevins_EMC> Is my Y goping to travel to New York?
[01:39:10] <bevins_EMC> at 300IPM, it might take awhile
[01:40:43] <andypugh> One might argue that a software e-stop is a wasted pin.
[01:41:22] <andypugh> the "Esc" key works at least as well, and the physical buttons probably want to actually cut power.
[01:42:18] <bevins_EMC> got a kernal dump message
[01:42:40] <andypugh> (i have both, the emc e-stop, the watchdog on the interface board and the physical e-stop buttons all kill the +12 and +24 power)
[01:43:00] <andypugh> Wow! That's bettter than I hoped
[01:43:06] <bevins_EMC> I could hardwire it to do that.
[01:43:12] <bevins_EMC> Except its 48vdc
[01:43:37] <andypugh> Yes, I have an effette CNC, I know
[01:44:13] <andypugh> Is the dump an emc error dump? If so, what does it say near the end?
[01:44:30] <Valen> last 4 lines or so usually actually have stuff in it
[01:44:52] <andypugh> I can nearly see it on the cam
[01:45:01] <bevins_EMC> http://pastebin.ca/1771519
[01:46:01] <andypugh> Ah, it is unhappy with a stepgen output going to two physical pins. I did wonder about that.
[01:46:18] <andypugh> (Line 210)
[01:46:27] <bevins_EMC> step pin allready linked?
[01:46:39] <Valen> I think you need 2 stepgens, but have them linked to the same axis
[01:47:03] <andypugh> Surely 1 signal can go to 2 places?
[01:47:28] <andypugh> In fact, that's an output, so of course it can.
[01:48:57] <andypugh> The problem is (and this is where my rather rudimentary HAL knowledge shows) is that one pin can't go to two signals.
[01:49:38] <andypugh> I am going to hard-code the stepgen to the p-port pin, I am sure there is a more elegant solution, but this ought to work.
[01:53:37] <andypugh> http://pastebin.ca/1771525
[01:54:21] <andypugh> Please don't take my files as-read, I am only a few months further up the learning curve than you.
[01:54:55] <andypugh> ie try to follow what I have done, and hopefully think of better ways
[01:56:18] <andypugh> The problem with that HAL file is that I have moved some of the parport-pin definitions to another part of the file, and that is not elegant.
[01:57:03] <bevins_EMC> Its not one pin going to two signal, its one signal going to two pins
[01:57:42] <bevins_EMC> Should I try it?
[01:57:49] <andypugh> Yes, I was using the terms "signal" and "pin" in the sense they are used inside HAL, and as they are viewed in HAL config
[01:57:53] <Valen> nothing to loose
[01:57:56] <andypugh> Yes, go for it
[01:58:10] <andypugh> The HAL net command syntax is:
[01:58:49] <Valen> andypugh think your HAL skillz are up to making another stepgen linked to the axis?
[01:58:55] <andypugh> net <signal name> <source pin> <sink pin> [<sink pin> ...]
[01:59:22] <bevins_EMC> it started
[01:59:38] <andypugh> Yes, I have a dual-stepgen version half finished in another window
[02:00:12] <Valen> well thats 90% of it
[02:00:17] <andypugh> where <signal name> is free-choice string, but the other pins are parts of HAL components
[02:00:18] <Valen> try it
[02:00:36] <bevins_EMC> My Zis backwards
[02:00:46] <Valen> gees picky bastard ;-P
[02:00:48] <bevins_EMC> My Z is backwards
[02:01:26] <bevins_EMC> hehe
[02:01:44] <bevins_EMC> the A is moving now. Both were moving for a short minute
[02:02:36] <andypugh> Was the Z always backwards?
[02:02:48] <bevins_EMC> In Mach I had to invert it
[02:02:59] <andypugh> Dual-stepgen variant, also totally untested:
[02:03:00] <andypugh> http://pastebin.ca/1771535
[02:04:14] <Valen> I think he will need that one to get both to home
[02:04:27] <Valen> but aside from that the last one will be simpler
[02:04:27] <andypugh> Simplest solution, edit the HAL so that there is a line saying
[02:05:02] <andypugh> setp parport.0.pin-07-invert 1
[02:05:25] <bevins_EMC> last file it dump[ed again
[02:05:30] <andypugh> (or something like that)
[02:05:43] <bevins_EMC> bad position 0
[02:05:55] <bevins_EMC> CNC-Router.hal.15 addf failed
[02:05:56] <Valen> that other one is a big change
[02:06:15] <Valen> get this one working first with your Z right way aroung
[02:06:17] <Valen> around
[02:06:25] <bevins_EMC> ok,
[02:06:26] <Valen> andypugh, he'll need that on both
[02:06:41] <andypugh> The Z is a single axis?
[02:07:18] <andypugh> Alternatively, you can add a minus sign to input_scale and _output_ scale in the ,ini file for the Z axis
[02:08:07] <andypugh> In fact, I think you can invert an axis in at least 4 different places, from the motor wiring back to the ini file
[02:10:37] <bevins_EMC> that didn't work it dumped saying parameter or pin "your statement" not found
[02:10:49] <bevins_EMC> But I thinkI can work with this. thanks for your help
[02:10:59] <andypugh> Which didn't work?
[02:10:59] <bevins_EMC> Hope I don't have to go back to Mach3
[02:11:12] <bevins_EMC> inverting z
[02:11:21] <andypugh> Let me actually check the docs.
[02:11:51] <andypugh> I am doing all this from memory, my EMC machine is powered down in the shed.
[02:12:03] <Valen> I would turn ours on to check
[02:12:04] <bevins_EMC> Whats it doing in there?
[02:12:06] <Valen> but the UPS is off
[02:12:21] <andypugh> It's 2am here.
[02:12:31] <andypugh> Even I don't CNC at 2am
[02:12:33] <bevins_EMC> Where are you? across the o0nd?
[02:12:36] <bevins_EMC> pond
[02:12:47] <andypugh> Aye, in the UK
[02:13:42] <andypugh> Very, very, useful link: http://www.linuxcnc.org/docview/html/
[02:15:22] <andypugh> setp parport.0.pin-07-out-invert 1 was what you wanted
[02:15:35] <andypugh> I forgot the -out- bit
[02:15:58] <andypugh> Put that in the bit of the HAL file that sets the parport pins up
[02:16:22] <andypugh> That will invert the sense of your Z-pin
[02:17:45] <andypugh> (With the camera, I can see he isn't even there)
[02:18:02] <andypugh> He's back!
[02:18:17] <bevins_EMC> hehe
[02:19:15] <bevins_EMC> that worked.
[02:19:30] <terrylm> Earlier I could not speak, but had noticed some discussion about how to make a homemade quadrature encoder. If the interested parties are still here: http://sourceforge.net/projects/quadwheel/
[02:20:10] <bevins_EMC> that worked.
[02:20:37] <bevins_EMC> anyway, the Y is still not slaved. the A is moving only now. I guess its on to reading
[02:20:43] <andypugh> Does that print on paper, or actually machine?
[02:22:41] <andypugh> I am disappointed that it isn't working, both sets of driver pins should be linked to the same place.
[02:23:14] <andypugh> I might have forgotten the amp-enable pins though
[02:23:25] <bevins_EMC> it worked for a few times.
[02:23:44] <terrylm> Question: stepper motors with encoders, what to hook the ecoder reader output to in hal?
[02:24:51] <andypugh> That's very odd.
[02:25:20] <andypugh> terrylm: An encoder module
[02:25:59] <andypugh> http://www.linuxcnc.org/docview/html//man/man9/encoder.9.html
[02:26:55] <andypugh> bevins_EMC: You might want to invert all the step pins too, some drivers work a lot better that way
[02:27:07] <bevins_EMC> 7 doesn't get reset or is that only for direction?
[02:27:23] <andypugh> Ah!
[02:27:25] <andypugh> That's it
[02:28:16] <andypugh> You want a reset on all step pins
[02:29:22] <danimal_garage> hi
[02:29:37] <andypugh> So pin-8 needs a reset line too.
[02:30:02] <terrylm> Yes, I have the hardware encoder hooked to the hal ecoder modules. What I don't know is what to do with the output from the hal encoder modules, there seems to be no obvious input pins anywhere?
[02:30:20] <terrylm> ecoder = encoder
[02:31:09] <andypugh> Reset means that the pin goes high (or low) at the beginning of the base thread, anf low (or high) at the end. That means that you don't have to use 2 base thread cycles per pulse.
[02:31:40] <andypugh> axis.n-position-feedback?
[02:32:13] <danimal_garage> terry: you need to add the encoders to the top of your ini
[02:32:38] <terrylm> Oh, thought I checked axis.*, I'll look again, thanks.
[02:32:40] <andypugh> terrylm: Sorry, axis.n.motor-pos-fb
[02:33:25] <danimal_garage> there's a line that says CONFIG= and has your firmware info, for mesa products anyways
[02:33:49] <andypugh> Normally it is linked (by stepgen) to the stepgen -position-fb pin, but if you have a real encoder, you can use that instead
[02:34:13] <danimal_garage> are my posts still not showing?
[02:34:20] <andypugh> good point danimal
[02:34:26] <danimal_garage> oh ok good
[02:34:33] <danimal_garage> thought i was still unregistered
[02:34:41] <andypugh> No, your post show, we are just ignoring you
[02:34:46] <danimal_garage> ahh ok
[02:34:49] <danimal_garage> good
[02:35:17] <andypugh> terrylm: Paralel port or Mesa (or Pico, or whatever) setup?
[02:35:50] <bevins_EMC> net zdir => parport.0.pin-07-out
[02:35:50] <bevins_EMC> setp parport.0.pin-08-out-reset 1
[02:35:55] <terrylm> OK, either stepgen -position-fb pin or axis.n.motor-pos-fb. Not using a mesa card, just parports so far.
[02:36:19] <bevins_EMC> Shouldn't that be 8-out? then followed by 8 reset?
[02:36:29] <bevins_EMC> 7 is a dir pin
[02:38:26] <andypugh> I think I said 8?
[02:39:08] <bevins_EMC> Thats whats in the file, 4 is like that also
[02:39:17] <andypugh> 7 is your & direction, I think, so that needs an invert.
[02:39:27] <andypugh> 8 should be a perfect copy of 4
[02:39:34] <bevins_EMC> I have 7 in as invert and it works
[02:39:53] <andypugh> & - Z (I have no idea how I got it _that_ wrong)
[02:40:43] <andypugh> Anyway, I need sleep.
[02:41:00] <bevins_EMC> Where are you ying the signal foir Y axis. sending it to the A motor (step-8, Dir-9)?
[02:41:08] <bevins_EMC> ok, thanks for the help
[02:41:09] <andypugh> Indeed
[02:41:44] <andypugh> The Y-axis stepgen output is being sent to both the 4/5 pair and the 8/9 pair
[02:42:32] <bevins_EMC> I see it
[02:43:29] <andypugh> Just one warning, if you run Stepconf again, it will overwrite all the changes.
[02:43:57] <bevins_EMC> ok,
[02:44:09] <bevins_EMC> I allready saved this file elswhere
[02:46:34] <andypugh> Good luck. And you will not need to go back to Mach, the tenacity of folk here when faced with a problem is a joy to behold. Somebody last night found a bug in a new kernel version (not the supported kernel even), and there was a workaround for him inside a couple of hours and a patch for the main software the next morning.
[02:47:40] <andypugh> Night all
[02:53:20] <terrylm> OK, stepgen.n.position-fg is an output pin currently tied to axis.n.motor-pos-fb which is an input.
[02:54:06] <terrylm> So I should break that and direct the encoder output to axis.n.motor-pos-fb instead?
[02:55:08] <terrylm> What becomes of stepgen.n.position-fb, just ignore it?
[02:57:41] <danimal_garage> cant you have them all together?
[02:57:50] <danimal_garage> wait nm
[02:58:06] <danimal_garage> hmmm
[02:58:48] <terrylm> I don't know, but think not.
[03:06:45] <WalterN> danimal_garage: did you get that plastic machined alright?
[03:07:31] <steves_logging> steves_logging is now known as steve_stallings
[03:10:27] <danimal_garage> terry, look at page 82 in the integrator's manual. I think you'd have your encoder output pin go to your stepgen.<chan>.position-fb or count-fb
[03:10:47] <danimal_garage> WalterN: i'll be working on it over the weekend.
[03:10:59] <danimal_garage> i did take a test cut, it definitely needs to stay cool.
[03:11:04] <danimal_garage> any tips?
[03:11:15] <WalterN> danimal_garage: did you read what I said earlier about cutting plastic?
[03:11:25] <WalterN> (guess not)
[03:11:28] <WalterN> (oh well)
[03:11:31] <danimal_garage> no, this is the first time i've been on all day
[03:11:39] <WalterN> lettseehere
[03:11:43] <danimal_garage> lemme see if it's still on the screen
[03:12:02] <WalterN> nope, I cant get back that far
[03:12:47] <WalterN> and I dont have logging enabled :(
[03:13:25] <danimal_garage> i saw it
[03:13:33] <danimal_garage> thanks, wish i saw it earlier lol
[03:13:50] <WalterN> really the key is a sharp tool
[03:13:53] <WalterN> thats all
[03:13:55] <danimal_garage> yea
[03:14:12] <danimal_garage> i just ordered a brand new endmill foor the majority of the pocketing
[03:14:12] <WalterN> I mean... hair splitting sharp
[03:14:21] <WalterN> is it a two flute?
[03:14:24] <danimal_garage> yes
[03:14:31] <WalterN> ok, should be good then
[03:14:40] <WalterN> what kind of plastic?
[03:14:44] <danimal_garage> pvc
[03:14:49] <WalterN> ok
[03:14:59] <WalterN> that stuff is uber smelly if it gets warm
[03:15:06] <danimal_garage> yea i noticed lol
[03:15:21] <danimal_garage> i had some stringy chips that rubbed
[03:15:27] <WalterN> compared to other common plastic used in a machine shop (delrin, UHMW...)
[03:16:01] <WalterN> what size cutter are you using/getting?
[03:16:08] <danimal_garage> i got 40 feet of 4" diameter solid pvc
[03:16:12] <danimal_garage> to machine
[03:16:30] <danimal_garage> the endmill is a 3/4" carbide, .125 corner radius
[03:16:37] <WalterN> hmm, ok
[03:16:47] <WalterN> low RPM
[03:16:49] <danimal_garage> i need the corner radius unfortunately
[03:16:58] <WalterN> 400 RPM I would guess
[03:17:08] <danimal_garage> ok, good to know
[03:17:12] <bevins> What are you machining?
[03:17:13] <WalterN> cause you dont want to smell more than is necessary
[03:17:16] <WalterN> heh
[03:17:26] <WalterN> are you using coolant at all?
[03:17:31] <bevins> in pvc pipe?
[03:17:49] <WalterN> bevins: solid PVC
[03:17:55] <danimal_garage> i can use coolant on the mill, but the lathe has cutting oil
[03:18:13] <bevins> ah! block of pvc.... Where would one find that?
[03:18:24] <danimal_garage> plastic suppliers
[03:18:26] <bevins> I could use some...
[03:18:44] <danimal_garage> my customer ordered it. scared to know what it costs
[03:18:46] <WalterN> where I used to work in Oregon we got it from Port Plastics in Portland, shipped to the coast
[03:18:54] <bevins> first gots to get this thing working.
[03:19:05] <danimal_garage> this came from port pladtics here in san diego
[03:19:11] <danimal_garage> plastics
[03:19:15] <WalterN> danimal_garage: I'll give you a hint... EvPeNsIvE
[03:19:19] <bevins> I used to live in San Diego
[03:19:24] <WalterN> *ex
[03:19:28] <danimal_garage> i live in escondido
[03:19:40] <bevins> I used to live in OB for 10 years
[03:19:54] <danimal_garage> WalterN: ouch, not looking forward to any potential scrap
[03:19:56] <WalterN> 4" diameter? PVC? yeah. Expensive
[03:20:24] <danimal_garage> i got 40 feet of that stuff
[03:20:37] <WalterN> a stick of the uber cheap stuff, UHMW, I would guess to be about $50
[03:20:53] <WalterN> 8' long
[03:21:05] <danimal_garage> not bad
[03:21:09] <WalterN> no
[03:21:15] <WalterN> but thats the cheapest stuff
[03:21:17] <WalterN> heh
[03:21:27] <danimal_garage> these are 5 footers
[03:21:32] <WalterN> PVC would be tripple that?
[03:21:39] <WalterN> 4x?
[03:21:51] <WalterN> 2x-3x more than UHMW
[03:21:54] <WalterN> I think
[03:21:57] <danimal_garage> wow
[03:22:03] <WalterN> didnt ever work with PVC much
[03:22:13] <danimal_garage> yea, i only work with metal
[03:22:17] <WalterN> when I did it was something rather small
[03:22:28] <WalterN> and I never saw the price of it
[03:22:45] <WalterN> I just know its expensive :)
[03:22:51] <danimal_garage> had to help out a buddy who got a big gov contract, and needed the stuff done by monday
[03:22:59] <WalterN> what does onlinemetals say?
[03:23:20] <WalterN> what are you making anyway?
[03:23:53] <danimal_garage> some filter dodad that's going to haiti
[03:24:17] <WalterN> actually I think Nylon and PVC are about the same cost wise
[03:25:11] <danimal_garage> $438 for 5 feet of nylon
[03:25:18] <danimal_garage> i didnt see pvc on there
[03:25:52] <WalterN> same
[03:26:11] <bevins> Why is everything referncing /etc/emc2/sample-configs? On my machine I just loaded, the is no sample-configs in there. did they change the structure?
[03:26:23] <WalterN> they would be about %20 more than what you could get it for locally I think
[03:27:17] <danimal_garage> interesting
[03:27:27] <danimal_garage> glad i stick to metal
[03:27:49] <WalterN> UHMW is the pits to machine sometimes
[03:27:59] <WalterN> too... soft
[03:28:16] <danimal_garage> i machined some foam pvc once
[03:28:24] <danimal_garage> that sucked
[03:28:30] <WalterN> foam?
[03:28:35] <danimal_garage> yea
[03:28:43] <danimal_garage> it's pretty high density though
[03:28:45] <WalterN> like air injected or something?
[03:28:51] <danimal_garage> they sell it in mcmaster carr
[03:29:03] <danimal_garage> they call it pvc foam
[03:29:15] <danimal_garage> not sure, it's just really pourous
[03:29:26] <WalterN> oh
[03:29:28] <WalterN> gotcha
[03:29:36] <WalterN> 90% of the plastic I worked with was UHMW and acetal
[03:29:43] <danimal_garage> usually just stuck to delrin
[03:29:46] <tomp> 40 bucks a foot http://www.usplastic.com/catalog/item.aspx?itemid=32417&catid=733
[03:29:46] <WalterN> delrin.. w/e
[03:30:07] <danimal_garage> aerospace stuff was always delrin
[03:30:22] <bevins> My couplings are made of delrin
[03:30:24] <bevins> hehe
[03:30:35] <WalterN> tomp: woah... I need a chunk now...
[03:30:45] <WalterN> :P
[03:30:55] <WalterN> lets see...
[03:31:00] <danimal_garage> well i guess i better start cutting this stuff up
[03:31:05] <danimal_garage> thanks for the tips
[03:31:12] <WalterN> yeah
[03:31:19] <WalterN> 3x more than UHMW
[03:31:22] <WalterN> or so
[03:32:02] <danimal_garage> WalterN: about 80 SFM?
[03:32:07] <WalterN> I looked at a few of the cheaper plastics for a fuel grain for my hybrid rocket engine
[03:33:37] <WalterN> danimal_garage: just dont spin it too fast, for the endmill I would say about 400-600RPM and maybe 200 for the lathe
[03:33:54] <WalterN> you can really hog the stuff off
[03:34:14] <danimal_garage> it's got thin walls too
[03:34:21] <danimal_garage> the part, that is
[03:34:34] <WalterN> how thin?
[03:34:41] <danimal_garage> i wonder how much it'll spring when i take it out of a constrained state
[03:34:43] <WalterN> oh, for the endmill part?
[03:34:48] <WalterN> after the lathe
[03:35:16] <WalterN> do you have a drawing of the part handy?
[03:35:23] <danimal_garage> i'm roughing out the pockets on the mill, then i'm spinning it
[03:35:32] <danimal_garage> turning it*
[03:35:46] <danimal_garage> i cant show ya unfortunately, it's confidential
[03:35:53] <WalterN> sure
[03:35:58] <danimal_garage> non disclosure agreenment and all
[03:35:58] <WalterN> :P
[03:36:14] <WalterN> * WalterN made oxidizer injectors for hybrid rocket before :P
[03:36:34] <danimal_garage> cool
[03:36:35] <WalterN> for a department of defense contract
[03:36:53] <WalterN> yeah it was :)
[03:37:02] <WalterN> then I got to see the test firing
[03:37:05] <WalterN> ha
[03:37:14] <danimal_garage> thats gotta be neat
[03:37:19] <WalterN> awesomeness, now I have to make my own
[03:37:40] <WalterN> anyways, how thin are the walls going to be?
[03:38:39] <WalterN> because plastic really likes to shrink/grow with just heat and a little pressure
[03:39:00] <WalterN> nevermind grabbing onto it with a three jaw
[03:39:14] <danimal_garage> depends.... between .125" and .200"
[03:39:29] <danimal_garage> i was planning on making a fixture
[03:39:44] <WalterN> k, how thick is the part you will be grabbing onto?
[03:40:01] <WalterN> same?
[03:40:17] <danimal_garage> yea
[03:40:20] <danimal_garage> about there
[03:40:29] <WalterN> problems
[03:40:31] <WalterN> hmm
[03:40:33] <danimal_garage> the whole thing is pprox that thick
[03:40:44] <WalterN> can you turn it before milling?
[03:40:49] <danimal_garage> except for 2 o ring grooves, which will be quite a bit thinner
[03:40:54] <WalterN> the inside part anyway
[03:41:19] <danimal_garage> i need to mill it first so i can get the boring bar in there, there's a tube in the center so i cant drill
[03:41:33] <danimal_garage> i dont have a trepan tool long enough to hog it out
[03:42:34] <danimal_garage> i was thinking of milling it out, then finish turing the id, then i might make a plug to fit the id and mount it on that to turn the od
[03:42:44] <WalterN> can you leave a little extra material on the end to grab onto in the lathe?
[03:43:21] <WalterN> oh, so you have to turn from both ends?
[03:43:36] <danimal_garage> i got pie jaws that are approx .2" deep i thought about using
[03:44:02] <danimal_garage> picture a cup, approx 4" in diameter, and 3 inches deep
[03:44:14] <danimal_garage> with a tube in the center, approx 1" in diameter
[03:44:58] <WalterN> hmm
[03:45:07] <WalterN> OAL?
[03:45:07] <danimal_garage> it's a somewhat complicated part
[03:45:14] <danimal_garage> 3.15"
[03:45:27] <WalterN> oh no sweat, ok
[03:45:37] <WalterN> I was thinking 2x-3x longer
[03:45:38] <WalterN> lol
[03:45:47] <danimal_garage> no, fortunately
[03:46:13] <tomp> should've been molded but no time
[03:46:27] <danimal_garage> yea, i'll be making the mold for them too
[03:46:32] <WalterN> dies are expensive :(
[03:46:40] <danimal_garage> but i gotta do 124 of them for now
[03:46:46] <tomp> you a lucky guy, good work to have
[03:47:09] <WalterN> yeah
[03:47:19] <WalterN> though 120 of them seems annoying
[03:47:21] <danimal_garage> i guess that depends on what you're setting aside to do it
[03:47:21] <WalterN> heh
[03:47:43] <danimal_garage> i usually dont do outside work, but this is for a friend
[03:48:12] <danimal_garage> and he had no other options really
[03:48:49] <danimal_garage> guess i shouldnt bitch, some people dont have any work
[03:48:56] <WalterN> yeah... I would probably machine an aluminum donut to fit inside so you can grab on to it, and maybe machine some soft jaws to go along with it so pressure is spread across a larger area
[03:49:32] <tomp> additive? weld 'em up and trim. http://www.youtube.com/watch?v=hIdtX4JoRpM
[03:49:34] <danimal_garage> WalterN: i'm gunna make a bung for it, and i can run a bolt through the center of the tube with a cap to hold it on
[03:49:56] <danimal_garage> to turn the outside
[03:50:03] <WalterN> ah
[03:50:15] <danimal_garage> i only got .07" to turn off the outside, and put 2 o-ring grooves in it
[03:50:18] <WalterN> how about using the center on the bolt too?
[03:50:39] <danimal_garage> no center on my cnc lathe, but i cant see needing it
[03:50:55] <danimal_garage> i'll indicate the fixture in
[03:51:23] <WalterN> guess you know know better, considering you have the drawing
[03:51:42] <WalterN> cant help any more without a sketch or something
[03:51:45] <WalterN> :P
[03:52:26] <danimal_garage> well the bung will be about 3.5" in diameter, 3 inches long. fairly beefy
[03:52:46] <danimal_garage> yea, i wish i could give ya one, but i'd get in trouble
[03:52:50] <WalterN> still, .2" of plastic wall will be a problem
[03:52:50] <tomp> bung = arbor?
[03:52:59] <danimal_garage> tomp: yes
[03:53:35] <WalterN> unless its thick in the middle
[03:53:38] <WalterN> I guess
[03:53:39] <danimal_garage> WalterN: there will be nowhere for the plastic to go, the arbor will be the exact size of the id of the part
[03:54:01] <danimal_garage> basically making it solid
[03:54:01] <WalterN> yeah, but plastic really likes to move around
[03:54:16] <WalterN> not PVC so much though
[03:54:17] <WalterN> hmm
[03:54:26] <WalterN> guess you will have to try it first
[03:54:35] <danimal_garage> i got .01" tollerance on the od, and i'm only taking .035" off the wall
[03:55:41] <tomp> isnt it tapered? hell of a mold with no draft over 3" (or lotsa slides )
[03:55:43] <danimal_garage> +-.01"
[03:55:59] <danimal_garage> yes, there's a draft on the id
[03:57:12] <WalterN> PVC maintainability is a lot like delrin/acetal
[03:57:47] <WalterN> and structural nature, as far as I could tell
[03:58:27] <danimal_garage> well hopefully i dont wing a part out when i'm turning it lol
[03:58:41] <WalterN> another reason to turn slow :)
[03:58:57] <danimal_garage> true
[03:59:08] <danimal_garage> well thanks for the tips, i'll give it a shot
[03:59:42] <WalterN> have fun, let me know how it goes
[03:59:59] <WalterN> * WalterN never got to make anything that large with PVC
[04:00:01] <danimal_garage> will do!
[04:00:26] <danimal_garage> this will be my first job on my cnc lathe
[04:00:36] <WalterN> nice
[04:00:55] <danimal_garage> hope it works lol
[04:00:55] <WalterN> * WalterN wants a CNC lathe :(
[04:01:09] <danimal_garage> get a hardinge HNC and join the family
[04:01:18] <WalterN> linky?
[04:02:06] <danimal_garage> http://smg.photobucket.com/albums/v20/danielwilcox/hardinge/
[04:02:53] <WalterN> oh... hmm
[04:03:47] <WalterN> I think I would rather have one of these... http://www.haascnc.com/details.asp?ID=TL-1&webid=LATHE_TL
[04:03:56] <WalterN> have one of them at work
[04:04:38] <danimal_garage> bit of a price difference
[04:04:51] <WalterN> probably
[04:04:55] <WalterN> :P
[04:04:57] <WalterN> oh well
[04:05:03] <danimal_garage> uhhh definitely lol
[04:05:26] <danimal_garage> 23k minimum for that
[04:05:33] <WalterN> http://spathengineering.com/ is the guy who I made a bunch of parts for
[04:05:33] <danimal_garage> 1k for a hnc lol
[04:06:10] <WalterN> 7,000lbs of thrust :D
[04:07:58] <danimal_garage> nice
[04:08:21] <danimal_garage> little more than my mustang lol
[04:08:32] <WalterN> haha
[04:09:00] <WalterN> it'd pick my little car up like it wasent there
[04:09:12] <WalterN> 2,000lbs for my car
[04:09:14] <WalterN> heh
[04:10:44] <danimal_garage> you must have a tiny car
[04:10:49] <tomp> 100pcs to do?
[04:11:00] <danimal_garage> 124 pieces
[04:11:13] <danimal_garage> 12 due monday
[04:11:24] <danimal_garage> the rest in a couple weeks
[04:11:30] <tomp> i estimate the stock is 24pcs short
[04:11:41] <danimal_garage> there's more coming
[04:11:56] <danimal_garage> this is what he gave me for the original order of 54
[04:11:57] <tomp> anyway the mandrel sounds good
[04:12:12] <danimal_garage> then he got another order
[04:12:14] <tomp> arbor bung thingy
[04:12:45] <danimal_garage> hopefully it'll work, i'll just use the same mastercam drawing, and change the toolpaths
[04:12:57] <danimal_garage> so it should be a perfect fit
[04:13:10] <tomp> but consider welding the bot & tube in , with a jig
[04:13:18] <danimal_garage> i cant
[04:13:21] <WalterN> tomp: it just feels like a center would help a lot... but I guess he dosent have one so...
[04:13:57] <danimal_garage> walter, this fixture wont be bumped off center when only cutting .035" of plastic
[04:14:31] <WalterN> *shrug*
[04:14:42] <WalterN> it would take less time to line up
[04:14:53] <danimal_garage> i'll turn it in the machine
[04:14:58] <WalterN> but it really dosent matter
[04:15:09] <WalterN> cause what you dont have is what you dont have
[04:16:26] <danimal_garage> i dont think you're picturing what i am
[04:16:57] <danimal_garage> hard to picture it without a print to look at i guess
[04:17:09] <WalterN> yeah
[07:25:29] <christel> [Global Notice] Good morning all! As you are aware we're about to start the migration over to ircd-seven shortly, I am about to take a snapshot of the services database and copy across topics and channelmodes (bans, invexes etc). This means that any changes you make to channel modes or services after this point (on hyperion) will be lost. We'll be a bit noisy as the migration goes on and will global to keep you updated. Thanks for your patien
[07:26:14] <Jymmm> * Jymmm straps in for the ride.... THIS IS GONNA BE BUMPY!!!!!
[07:26:32] <Danimal-office> * Danimal-office slaps Jymmm around a bit with a large trout
[07:26:48] <Jymmm> They are about to migrate ALL the servers
[07:57:00] <christel> [Server Notice] Hi, for users on calvino we would encourage you to make sure that your client is set to reconnect to main rotation (chat.freenode.net) as this server will not be immediately available after migration. Thank you!
[08:00:53] <christel> [Global Notice] Hi all, services and channel states have now been migrated over to the new production network. We're migrating utility bots/pseudoservers as we speak and we're nearly ready for users. Users connected to calvino, crichton, kubrick, leguin and verne may wish to make sure they are re-connecting to chat.freenode.net as these servers will not be immediately linked on newnet as they are pending upgrades first. Thank you!
[08:29:48] <christel> [Global Notice] Hi all, The migration is complete! newnet is up and running and you may now manually connect to irc.freenode.net, ports stay the same, however SSL listens on ports 7000 and 7070 if you wish to connect via SSL. We'll be taking down hyperion servers momentarily and we shall see you on the other side! Thank you!
[08:35:10] <ChanServ> [#emc] "This is the #emc channel - talk related to the Enhanced Machine Controller and general machining. Website: http://www.linuxcnc.org/, wiki at http://wiki.linuxcnc.org/"
[08:48:03] <christel> [Global Notice] The migration is complete and went smoothly, thank you for your patience while we transferred state from hyperion to seven, thank you to seven and charybdis developers for making ircd-seven happen and than you to freenodes infrastructure team for all getting dug in! Website FAQ is updated, as is our blog. You may wish to familiarise yourself with changes. Thanks!
[08:48:26] <Jymmm> EbiDK|AWAY: Please fix your client. Exit the channel, change your nick, then rejoin #emc.
[08:53:02] <Jymmm> cradek: Freenode servers are on new software now. that *should* help with the attacks, but if you see any issues, toss the channel back on +R please.
[08:53:09] <Jymmm> Oh crap
[09:25:45] <Jymmm> WTH?!
[09:32:03] <micges> hi yoyoek1
[09:32:21] <micges> Jymmm: channel is +r?
[09:32:51] <Jymmm> not at the moment, but pretend it is
[09:33:18] <micges> heh
[09:46:14] <Jymmm> But, if you ever want to check for yourself: /mode
[09:50:58] <lilalinux_away> lilalinux_away is now known as lilalinux
[09:53:53] <Jymmm> alex_joni: hey
[09:54:20] <Jymmm> alex_joni: I've been looking for you
[09:56:32] <Valen> sounds ominous
[09:59:52] <Jymmm> alex_joni: Alright, you have till I finish wiring the detonator to your car to speak up, then I'm going to bed.
[10:04:25] <Jymmm> Valen: "I have NO IDEA where you would get that from"
[10:08:02] <Jymmm> alex_joni: Alright, I'm outta here. Remember the disarm sequence is: llrrllrlllrrrlllrluudduuduudlrrllrlddduuuuuddudlld and that has to be entered within 1.5 seconds.
[10:08:57] <Jymmm> alex_joni: OH and the self-destruct is easy: just miss any one or more sequences.
[10:15:46] <EbiDK> EbiDK is now known as EbiDK|AWAY
[10:37:52] <frallzor> ahoy hoy
[10:38:45] <Valen> think http://cgi.ebay.com.au/CNC-XY-XYZ-Table-20mm-Linear-44-Rail-Guideway-System_W0QQitemZ140240954995QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item20a7032673#ht_1908wt_940 would be much chop on a gantry style mill
[10:38:48] <Valen> for steel
[10:38:55] <Valen> not too heavy duty but still
[10:39:47] <Valen> how tight are the ball bearing race type slides?
[10:51:25] <frallzor> its interesting to see how UPS is trying to get my package from china to sweden
[10:51:48] <frallzor> china>korea>alaska>Kentucky>? atm =)
[10:54:07] <frallzor> but at least its located at a world wide hub now so who knows, maybe theyll aim correct this time
[10:56:17] <Valen> its following a great circle route?
[10:56:28] <frallzor> ?? =)
[10:57:24] <frallzor> they havent heard about sustainable development, thats for sure :P
[12:06:00] <lilalinux> lilalinux is now known as lilalinux_away

[15:53:48] <archivist> andypugh, you had gone to bed by the time I saw PM
[15:54:20] <andypugh> I can't even remember what I said.
[15:55:00] <archivist> you were having trouble speaking in irc http://blog.freenode.net/
[15:55:17] <andypugh> Ah, yes. I got it figured out eventually.
[15:55:50] <andypugh> It's probably a good idea to say "hi" to folk as they log on there and warn them that we can't necessarily see what they are writing.
[15:56:46] <archivist> it is/was +R due to spam but that should not be needed after the irc software update
[16:00:48] <andypugh> I am no sure how typical my client is, but the message about needing to register a nickname was rather cryptic.
[16:04:31] <andypugh> pyvcp lets you add buttons to the Axis Gui. Is there a way to remove standard controls so that others with different behaviour can replace them? (This question is rather prompted by a query on the mailing list)
[16:11:34] <tomp> tomp is now known as tom3p
[16:12:14] <tom3p> :) "It's probably a good idea to say "hi" to folk as they log on there and warn them that we can't necessarily see what they are writing." hmm catch 22 here
[16:12:41] <tom3p> or do you see the login?
[16:13:19] <christel> [Global Notice] We'll be restarting services quickly in a moment to make ChanServ leave your channels now that the usercount is up and channels are once again populated by 'real users'. Apologies for the inconvenience, and thank you for your patience throughout the migration!
[16:15:54] <andypugh> You see the "joined the chat room"
[16:16:42] <andypugh> And then can sort-of guess from the silence that they might be talking to themselves.
[16:16:53] <tom3p> ah! clever. in mine i do see eg: e3m [~e3m@public-gprs81679.centertel.pl] entered the room. never noticed before
[16:17:12] <tom3p> hello e3m
[16:19:35] <tom3p> e3m please register today 'you are the winner!' :0 blink blink blink
[16:23:06] <andypugh> the command is "/msg nickserv <password you want to use> <email address to send confirmation to>"
[16:25:18] <tom3p> he's on, he sent me private anyway
[16:25:40] <tom3p> so, the technique is missing 'might be trolling'
[16:36:59] <lilalinux> lilalinux is now known as lilalinux_away
[16:37:54] <lilalinux_away> lilalinux_away is now known as lilalinux
[16:40:16] <numen> tom3p now, my hal file works
[16:40:36] <numen> with the set to zero, the spindle, the cooling and so on
[16:45:56] <Danimal-office> hi
[16:47:39] <Danimal-office> i think this registration crap has single handedly killed this channel
[16:47:52] <Danimal-office> lol
[16:48:19] <archivist> or made it peaceful :)
[16:48:32] <Danimal-office> na, i'm still here
[16:50:02] <Danimal-office> what's that grey line for?
[16:50:52] <archivist> I see a red line
[16:51:15] <Danimal-office> it's grey on all my computers
[16:55:16] <jthornton> I don't see any lines
[16:56:15] <archivist> only the enlightened see :)
[16:56:22] <jthornton> lol
[16:56:37] <Danimal-office> lathe done yet??
[17:04:36] <jthornton> LOL, closer than it has ever been... been plowing and shoveling snow all morning
[17:07:31] <danimal_garage> nice, got the phase converter in?
[17:13:49] <L84Supper> anyone have any news on the support for the Beagleboard? The last I heard the port was being handed off to the RTAI developers
[18:36:42] <Danimal-office> it'd be cool if it had digital audio
[18:53:27] <danielfalck> test
[18:53:43] <danimal_garage> fail
[18:53:47] <danielfalck> ok, guess I am identified and logged in- sorry
[18:55:28] <danielfalck> for anyone out there trying to remember how they set things up on IRC in the first place: http://freenode.net/faq.shtml#nicksetup
[19:03:11] <jthornton> danimal_garage: I have some parts of the phase converter done, then I took the motor out to finish up all the connections that use to go to the interface board
[19:09:31] <andypugh> Now to see if the little servos can move the lathe better or worse than the steppers do. They only have a 22mm dia rotor, it pulls out through the bearing housing...
[19:13:53] <danimal_garage> whats up with this thing
[19:33:57] <alex_joni> Jymmm: hi
[19:53:11] <micges> hi bassogigas
[19:53:23] <micges> how is your machine going?
[19:53:26] <bassogigas> hi
[19:53:47] <bassogigas> oh, i've updated to last version of emc
[19:54:00] <bassogigas> and it started to work much better
[19:54:20] <bassogigas> i dunno why i didn't do it earlier
[19:55:35] <bassogigas> the most interesting thing that the motion became better. i should read what's new carefully because i don't understand why )
[19:56:31] <micges> from what version to what you've upgraded?
[19:56:40] <bassogigas> erhhhh
[19:56:50] <bassogigas> 2.2.1 afair
[19:56:57] <danimal_garage> wowsers
[19:57:10] <micges> and what type of drivers you have? servo or steppers?
[19:57:19] <bassogigas> steppers
[19:57:31] <micges> parport?
[19:58:05] <bassogigas> i'm not that advanced user but i think yes
[19:58:24] <micges> sorry
[19:58:37] <micges> you're using parrallel port?
[19:58:56] <bassogigas> i understood what means parport )
[19:59:06] <bassogigas> i use old LPT
[19:59:31] <bassogigas> yep
[19:59:35] <bassogigas> parport
[19:59:42] <micges> and configuration made by stepconf ?
[20:00:03] <bassogigas> i chose stepper_mm
[20:00:20] <bassogigas> i didn't use stepconf.
[20:00:22] <micges> ok I see
[20:00:44] <bassogigas> if you mean a new to 2.2.1 tool from emc menu
[20:00:59] <bassogigas> for automatic configuration
[20:01:05] <bassogigas> is it it?
[20:01:09] <micges> yes
[20:03:05] <bassogigas> no, i saw this feature, raised eyebrоw with applause and forgot until better times )
[20:04:31] <micges> hmm
[20:05:02] <micges> there was no significant change to parportdriver or stepgen module
[20:05:41] <bassogigas> so i supposed namely this and a little bit amused
[20:05:46] <micges> maybe overall improve caused your better motion
[20:06:04] <bassogigas> yep i think this in this case too )
[20:07:53] <bassogigas> but many features i was thinking about while using 2.2.1 with pleasure i found in 2.3.4
[20:08:30] <micges> cool
[20:08:33] <bassogigas> the update was very useful.
[20:08:38] <bassogigas> but.
[20:08:44] <bassogigas> i
[20:09:12] <bassogigas> i )) almost hate ubuntu 8.04 for it's stupid X control
[20:09:49] <bassogigas> i cannot use 1024x768 от 15'' on crt display
[20:10:00] <bassogigas> monitor
[20:10:21] <micges> it's driver issue iirc
[20:10:26] <bassogigas> xorg.conf significantly changed
[20:10:48] <bassogigas> why did they do it.
[20:10:57] <micges> no idea
[20:11:13] <bassogigas> so now i have to F*** my brain with modes
[20:11:15] <micges> it was working on 6.06 ?
[20:11:23] <bassogigas> yep 6.06
[20:11:34] <bassogigas> it was working, yes
[20:11:37] <danimal_garage> anyone familiar with mcx?
[20:12:11] <micges> try restarting in safe mode and regenerate x configuration(form menu)
[20:12:23] <micges> it ofet helps
[20:12:29] <micges> often*
[20:12:59] <danimal_garage> i'm trying to set up my machine control definitions for my lathe, and it keeps telling me i dont have a valid axis combo defined
[20:13:38] <micges> danimal_garage: who is telling you?
[20:14:10] <danimal_garage> the software
[20:14:21] <micges> can you pastebin error?
[20:15:29] <danimal_garage> it says "this machine does not have any valid axis combinations defined and cannot be used in a toolpath group"
[20:15:57] <micges> in stepconf?
[20:16:18] <danimal_garage> oh i'm asking about mastercam, sorry. guess you didnt see my first post
[20:16:43] <micges> guess not
[20:16:56] <micges> its ok
[20:17:21] <danimal_garage> wrong place with it i guess, but i know there's people on here using mcam
[20:17:27] <danimal_garage> for it*
[20:17:44] <micges> they're sleeping now :P
[20:28:38] <andypugh> Well, the result of my experiment is that my cute little servo motors are not up to the job of running my lathe.
[20:28:54] <archivist> aw
[20:29:50] <andypugh> I think that they would be good for a mini-mill, and as they are NEMA23 would be a bolt-in upgrade for somebody. So I can't decide whether to sell them on (with the matched drivers) or to hang on to them for a future project.
[20:30:39] <archivist> if its just a torque issue you could try some gearing
[20:32:07] <andypugh> I already have 2:1 gearing on the X but there is no real option on the Y (space limits mean that 14 tooth pulleys is the maximum, which is also the effective minimum.
[20:32:53] <andypugh> I could probably get a significant performance increase by swapping the 20mm X ballscrew for a 12mm.
[20:34:12] <archivist> in the move from work to home I cant find my lathe pc hard disk (with the setup on it)
[20:39:17] <anonimasu> andypugh: sell them and buy better ones off ebay
[20:40:11] <andypugh> I have 2 motors and 3 drivers. I wonder if it is worth picking up another motor and selling them all as a kit?
[20:51:34] <kloeri> [Global Notice] Hi all. As part of the migration to ircd-seven channel mode +R was replaced by channel mode +q $~a. Channel operators can use /mode ##channel -q $~a to let unidentified people talk again. Feel free to jump into #freenode if you should have any questions about this. Thank you for using freenode.
[21:06:36] <acemi> what are the differences between halui.program.stop and halui.abort
[21:07:40] <frallzor> heh, my package from china has gone china>korea>Alaska>USA>? destination: swe odd route ey =)
[21:09:49] <micges> acemi: there is no significant difference
[21:10:27] <micges> I think that they even are the same
[21:10:58] <acemi> ok, then I'll only put an abort button for my panel
[21:20:22] <L84Supper> was there any crossover in the past between EMC and any Orocos development?
[21:20:58] <andypugh> Hmm, I get a lot of:
[21:21:29] <andypugh> (Messages too long to post) then an Error1
[21:21:45] <andypugh> "/System/Library/Frameworks/ApplicationServices.framework/Frameworks/HIServices.framework/Headers/Icons.h:864: error: ‘IconGetterUPP’ has not been declared"
[21:21:57] <andypugh> (Not length, it was the leading / was the problem)
[21:22:45] <andypugh> Then : make: *** [stdafx.h.gch] Error 1
[21:22:58] <andypugh> And it stops. Of course it might have stopped because it finished..
[21:23:58] <andypugh> Ooops! Sorry chaps, wrong IRC channel. I will go away and beat myself with sticks.
[21:29:50] <danimal_garage> can i help?
[21:30:10] <andypugh> Do you have your own sticks?
[21:30:37] <danimal_garage> yes
[21:30:47] <danimal_garage> they're metal sticks though
[21:30:52] <archivist> I have nails
[21:31:07] <danimal_garage> i have a rusty spoon
[21:31:21] <archivist> this is gonna hurt :)
[21:31:37] <danimal_garage> wont hurt me!
[21:31:43] <archivist> nor me
[21:32:03] <danimal_garage> then whats the problem?
[21:32:20] <archivist> the blood on the floor
[21:32:30] <danimal_garage> we'll drain it first
[21:32:44] <danimal_garage> meat hook, bath tub
[21:33:21] <danimal_garage> i have alot of acid kicking around for my anodizing
[21:33:33] <danimal_garage> it'll disolve flesh pretty well
[21:33:55] <danimal_garage> man, this took a turn for the ugly, huh
[21:34:05] <danimal_garage> i'll go back to my rusty spook
[21:34:28] <danimal_garage> but i am gunna dull it some more
[21:34:32] <danimal_garage> spoon*
[21:35:40] <andypugh> Acid is no good for dissolving flesh. You want a lime pit, or lots of caustic soda.
[21:35:48] <andypugh> Hang on, what am I saying?
[21:38:22] <anonimasu> mhm.. try floruic acid..
[21:38:40] <anonimasu> will dissolve the ceramic drain ^_^
[21:38:56] <andypugh> That just makes bones go all rubbery, though that might make me easier to pack
[21:40:54] <danimal_garage> muriatic acid?
[21:41:12] <danimal_garage> i think you're thinking of lye, not limes
[21:41:24] <danimal_garage> sodium hydroxide
[21:41:48] <danimal_garage> that does work quite well
[21:42:20] <danimal_garage> i've burned off my finger tips cleaning stuff with some soap that contained sodium hydroxide
[21:42:30] <andypugh> LIme == CaO, Caustic Soda == Sodium Hydroxide.
[21:42:55] <andypugh> I burned y arm dropping red-hot metal parts into molten sodium hydroxide...
[21:43:00] <danimal_garage> limes are what you put in caronas
[21:43:24] <danimal_garage> coronas*
[21:44:54] <andypugh> (Molten sodium hydroxide is a very good heat-treatment bath for certain applications)
[21:45:12] <alex_joni> http://en.wikipedia.org/wiki/Lye
[21:45:17] <alex_joni> vs.

[21:46:18] <andypugh> http://en.wikipedia.org/wiki/Calcium_oxide
[21:50:17] <andypugh> A pit of quicklime is the traditional way to dispose of bodies. Not that I ever have.
[21:50:25] <andypugh> That's just a rumour.
[21:58:20] <danimal_garage> woooo this cutting oil smoked my garage up good
[22:02:48] <danimal_garage> does opencam work decent?
[22:28:28] <archivist> fancy seeing you next door alex_joni
[22:28:47] <alex_joni> next door?
[22:28:52] <archivist> freenode
[22:28:56] <alex_joni> ah
[22:29:01] <alex_joni> just left ;)
[22:29:32] <archivist> I need to grab a tame staffer to rescue a chan
[22:29:41] <alex_joni> stats p
[22:30:04] <alex_joni> not much to chose from :)
[22:32:44] <archivist> I know a couple that are away at the moment, shall just have to wait
[22:55:08] <christel> [Global Notice] Hi all, Some of you (irssi users in particular) have had some problems regarding our SSL certificate. There's some instructions/information over at http://freenode.net/irc_servers.shtml Thanks to Bazerka and tomaw for investigating the issue and figuring it out!
[23:06:36] <andypugh> I get the impression that some ner-do-well is trying to spoil our fun.
[23:07:54] <archivist> its hell in #freenode at the moment
[23:08:00] <alex_joni> saw that
[23:09:58] <numen> what is with freenode? allways netsplit or disconnects...
[23:10:18] <alex_joni> they are under some attack
[23:10:32] <numen> ok...
[23:10:42] <archivist> I saw server reboot as the reason a few secs ago
[23:13:16] <danimal_garage> terrorists
[23:14:11] <alex_joni> danimal_garage: not quite ;)
[23:14:13] <alex_joni> but close
[23:14:35] <alex_joni> alien terrorists
[23:22:46] <alex_joni> terrylm: is it enabled?
[23:23:26] <alex_joni> how did you determine there's no step?
[23:24:49] <alex_joni> I doubt you can see it with hal meter
[23:25:04] <alex_joni> with halscope you need to make sure you have the halscope function in the base thread
[23:25:31] <alex_joni> can you pastebin your hal file?
[23:26:09] <alex_joni> open the hal file in your favourite editor
[23:26:15] <alex_joni> select all text, copy (ctrl-c)
[23:26:27] <alex_joni> open a webbrowser, go to http://pastebin.ca/
[23:26:51] <alex_joni> paste the text (ctrl-v), then hit submit
[23:27:19] <alex_joni> danimal_garage: now you should
[23:27:34] <alex_joni> I set channel to +z (means ops can see what unregistered people are saying)
[23:34:59] <Martinp23> Hi folks! A few moments ago that we suffered a rather large split. This was because a minor core code update to fix default channel mode settings did not go smoothly on a subset of servers, causing them to restart. We've made procedure changes so as not to let it happen again and we deeply apologise and thank you for using freenode! If you have any problems, as ever, #freenode is open to help.
[23:43:38] <alex_joni> terrylm: can't spot anything wrong with it
[23:43:47] <alex_joni> if emc2 doesn't fault, then it's working
[23:44:07] <alex_joni> because it's set up to use stepgen position as the feedback
[23:44:28] <alex_joni> so if the stepgen wouldn't work, emc2 would error with "following error.." message
[23:47:36] <alex_joni> numen: zmc?
[23:47:49] <alex_joni> ah, you mean the channel mode?
[23:50:57] <numen> yes
[23:51:11] <alex_joni> http://freenode.net/using_the_network.shtml
[23:51:13] <Eric_K> was the channel that bad?
[23:51:31] <alex_joni> it's not moderated :)
[23:52:05] <Eric_K> now
[23:53:13] <alex_joni> well.. I only set +z, not sure how the +m happened
[23:55:59] <danimal_garage> shenanigans
[23:56:14] <danimal_garage> hmm lunch time
[23:56:25] <Eric_K> well, at least it led me to change my subscription to the email list to an account that I actually read
[23:56:39] <alex_joni> * alex_joni is off to bed
