[00:00:38] <JT-Shop> I don't know one from the other
[00:00:50] <Tom_itx> for this it probably doesn't matter much
[00:01:47] -!- stsydow has quit [Remote host closed the connection]
[00:01:50] <tjb1> Anyone know how to tell if a meter socket supports a certain form size meter?
[00:02:22] <JT-Shop> Tom_itx: I gotta run
[00:03:39] <Tom_itx> np
[00:04:08] <Tom_itx> attiny13 may do ok
[00:04:15] <Tom_itx> looking..
[00:05:03] <Tom_itx> dip 8
[00:05:18] <Tom_itx> int0
[00:05:21] <Tom_itx> will work fine
[00:07:55] <JT-Shop> cool
[00:08:15] <Tom_itx> i'll make a studio 4 project for it
[00:08:22] <Tom_itx> and post it in that same directory later
[00:08:43] <Tom_itx> won't take long..
[00:08:55] <JT-Shop> Ok, thanks
[00:09:04] <JT-Shop> I have to go start cooking now
[00:09:11] <Tom_itx> i'll put it under tiny13 directory so you know
[00:09:33] <JT-Shop> ok thanks
[00:10:46] <JT-Shop> attint This product has been retired from our catalog and is no longer for sale.
[00:10:56] <Tom_itx> should only take 10-15 min...
[00:10:58] <JT-Shop> attiny13 seems to be retired
[00:11:05] <Tom_itx> look for attiny13a
[00:11:08] <Tom_itx> pico power
[00:11:16] <Tom_itx> i bet mouser has em
[00:11:56] <Tom_itx> you want it to trigger on the rising edge right?
[00:12:02] <JT-Shop> yes
[00:12:22] <Tom_itx> figure on an external pulldown on that pin to be safe
[00:12:25] <Tom_itx> 10k or so
[00:12:28] <Tom_itx> 100k
[00:12:30] <Tom_itx> whatever
[00:12:32] <JT-Shop> yea $0.95 each on digi key
[00:12:53] <JT-Shop> http://www.digikey.com/product-detail/en/ATTINY13A-PU/ATTINY13A-PU-ND/1914671
[00:12:59] <Tom_itx> k, i'll use the 13a as the target
[00:13:12] <JT-Shop> ok thanks
[00:13:24] <JT-Shop> I'll check back in a bit
[00:26:00] <Tom_itx> ok that will work in studio 4 or the programmers notepad
[00:26:06] <Tom_itx> i compiled it with both
[00:26:41] <Tom_itx> had to rename a couple registers but it's basically the same file as the tiny10
[00:28:53] -!- asdfasd has quit [Ping timeout: 256 seconds]
[00:31:34] <Tom_itx> factory default clock rate is 9.6Mhz internal osc on that part
[00:34:06] <Tom_itx> that would be #define M_CPU 9600000 right?
[00:34:20] <Tom_itx> err F_CPU
[00:35:59] <PCW> andypugh: what do you think of a gantry homing comp to avoid the gantrykins nastyness
[00:36:50] <andypugh> It's probably doable. I guess it would store an offset between the two sides.
[00:37:54] <PCW> Yes home to and of sw1 and sw2
[00:37:55] <PCW> save offsets when backing off switches
[00:37:57] <andypugh> Though the gantrykins nastiness probably ought to be fixed by fixing the non-trivkins nastiness in general, which may have been done in ja3
[00:38:18] <micges> it is
[00:38:33] <micges> it is fixed in ja3
[00:39:20] <PCW> a simple gantry config should not expose the 'gantrynessl to the user at all
[00:39:23] <andypugh> So, an auto-world after home is probably all that is needed to make Gantrykins as nice as pie.
[00:41:01] <micges> note that after any errors motion goes back into joint mode
[00:41:17] <micges> so mode must be checked not only after homing
[00:41:47] <PCW> Thats still fairly ugly for a simple gantry machine
[00:42:20] <PCW> where all thats really needed is de-racking when homing
[00:42:36] <micges> in ja3 there is gentrivkins that will hide gantryness
[00:43:10] <micges> it is trivkins with ability to map axes to joints
[00:43:39] <micges> with it it will never be in joint mode (no ability to move joint from gui)
[00:44:25] <PCW> how does that help gantry homing?
[00:44:33] <andypugh> But homing is a joint-thing not an axis thing?
[00:44:57] <PCW> Oh I see joints for homing only
[00:45:23] <micges> yes
[00:45:34] <micges> just home all button
[00:45:49] <PCW> does that work now?
[00:46:18] <micges> it was 1.5 year ago iirc
[00:47:35] <PCW> Theres a hack the software stepgen that people are using for gantry homing by gating the step output with the limit switches
[00:47:59] <PCW> which of course does not work with hardware stepgens
[00:48:22] <PCW> is there some reason JA3 is not merged?
[00:48:51] <PCW> seems like the cats meow
[00:48:53] <andypugh> I think because it breaks many configs.
[00:49:02] <micges> all configs
[00:49:10] <PCW> yow
[00:49:18] <andypugh> Easy fix?
[00:49:41] <andypugh> As in, the same mod to all configs, that could potentially be scripted?
[00:50:04] <micges> most configs need addition of few section of ini file and hal names changes also
[00:51:23] <andypugh> So, in theory the INI could grow a [VERSION] entry, and if out-of-date a script could add/alter as required?
[00:51:26] <micges> new [KINS] and [AXIS_X] [AXIS_Y] and [AXIS_0] and so on changes to [JOINT_0]
[00:51:44] <micges> yep
[00:52:13] <andypugh> How busy are you :-)
[00:52:23] <micges> but in hal axis.0... needs to be changed to joint.0..
[00:52:41] <micges> ha!
[00:54:03] <micges> good thing is that ja3 is working, got many machines on it
[00:54:23] <PCW> is it up-to date
[00:54:27] <PCW> ?
[00:54:36] <micges> noo
[00:54:59] <andypugh> It gets merged occasionally, doesn't it?

[01:02:28] <micges> (master in ja3, if that's helps)
[01:03:30] <Tom_itx> ok JT-Shop i think that should do. i don't have a target to test it on but it looks ok and compiles

[17:01:08] <andypugh> I just had a rather random thought. My Ikea lights are 5V / 0.75W. Well under the current capacity of the 7i64. So I can easily turn the lights on and off with GPIO. So far so sensible.
[17:01:52] <andypugh> But, if i can do that, I can turn the lights on-and-off synchronised to the spindle. So I could freeze the work to see what was happening :-)
[17:02:16] <jthornton> cool
[17:03:40] <pcw_home> JT-Shop: AVRs are flash and I think good for 10,000 reprograms
[17:06:47] <pcw_home> I ordered this to do some LED as strobe light testing:
[17:06:49] <pcw_home> http://dx.com/p/diy-60w-4000-5000lm-square-white-led-module-dc-33-35v-150675
[17:07:04] <syyl_ws> thats very safe to work, andypugh ;)
[17:07:10] <syyl_ws> "oh spindle is stoped"
[17:07:14] <syyl_ws> *touch*
[17:07:21] <syyl_ws> blood goes everwhere
[17:07:24] <syyl_ws> :(
[17:07:41] <pcw_home> with horror movie strobe light effects
[17:07:45] <andypugh> There would be that minor drawback, yes.
[17:08:09] <syyl_ws> that might be interesting, pcw_home ;)
[17:08:14] <andypugh> Perhaps I should use red LEDs to disguise the blood?
[17:08:21] <syyl_ws> great idea!
[17:08:46] <L84Supper> be sure to post a youtube with a creepy soundtrack
[17:09:43] <andypugh> Now, where can I buy key-steel on a bank holiday at 5pm?
[17:09:58] <pcw_home> I was going to use a stepgen phase locked to the motor to get minimum jitter and controllable pulse width
[17:10:31] <archivist> andypugh, you make!
[17:10:32] <andypugh> Or, for that matter, some coolant?
[17:11:31] <andypugh> Ah, archivist. Last time I was in Cromwell Tools they had Castrol Cooledge on a special offer at £60 for 20 litres. I don't think I need 20 l
[17:11:54] -!- mourner has quit [Quit: mourner]
[17:12:23] <archivist> some stuff is just plain overpriced
[17:13:03] <andypugh> That's a lot cheaper than normal..
[17:13:04] <archivist> I tend to use an oil can and whatever leftovers I have
[17:13:54] <andypugh> Hysol is £160 for 20l.
[17:14:25] <andypugh> Or you can buy it in 208L drums, for £1588!
[17:14:37] <archivist> the other week I was mixing axle/gear oil with hydraulic(automatic gearbox) and engine oil
[17:15:13] <L84Supper> I do the same in my waste oil tank
[17:16:02] <L84Supper> do you have to pay a recycler in the UK to deal with it?
[17:16:31] <archivist> supposed to yes
[17:17:30] <archivist> or get a recycler to collect for free or take to the council tip or be imaginative
[17:17:36] <JT-Shop> pcw_home: thanks
[17:17:39] <L84Supper> Walmart takes 5 gallons / day for free here
[17:18:07] <andypugh> I quite like the idea of running with neat oil for coolant. It ought to go mouldy more slowly.
[17:18:07] <archivist> do they heat their store with it
[17:18:33] <archivist> we used neat oils at the clockworks
[17:19:39] <archivist> just lose a bit, stays clean looking though
[17:23:05] <L84Supper> krap that funky EMCO CNC lathe on ebay sold
[17:23:06] <syyl_ws> running oil as a cooleant is a bit horror in my mind
[17:23:20] <syyl_ws> oil mist everywhere
[17:23:26] <syyl_ws> whole machine gets covered with oil
[17:23:52] <andypugh> Sounds good to me, less rust.
[17:23:56] <syyl_ws> saw a few index lathes that run with cutting oil
[17:23:58] <pcw_home> machine and operator well lubed
[17:24:04] <syyl_ws> looks like crap after a few years :D
[17:24:19] <syyl_ws> i want no oil mist in my lungs ;)
[17:24:32] <syyl_ws> i like the ability to breathe
[17:25:46] <pcw_home> must be an explosion hazard if too misty
[17:26:30] <syyl_ws> machines that run with cutting oil need a automatic fire extinguisher
[17:26:33] <L84Supper> http://www.ebay.com/itm/I-D-Grinder-Precision-Work-Head-w-Control-Box-/251215802710?pt=LH_DefaultDomain_0&hash=item3a7da0f156

[19:36:08] <JT-Shop> it
[19:36:13] <JT-Shop> 's all new to me
[19:36:17] <cradek> a few are a little less basic than that, but none are programmable

[19:37:01] <cradek> yeah they're almost exactly like our various hal components
[19:37:06] <archivist> hmm define programmable
[19:37:24] <cradek> well the simple ones anyway
[19:37:28] * cradek kicks archivist under the table

[19:56:00] <andypugh> Cavers have been known to use tipping buckets to convert a constant dribble into an occasional deluge, which can, over time, open up mud-chocked passageways.

[19:57:25] <andypugh> ie, placed on a surface plate it meaures half a degree.

[20:06:21] <archivist> check other angles first
[20:06:35] <archivist> may be a scaling error
[20:07:30] <andypugh> I doubt I will ever need more than 5 degrees. I wanted it for setting up for hobbing. Larger angles can use the table graduations, normally.

[20:28:21] <andypugh> cradek: I agree in principle. But It is also nice that with a uP when the customer realises what he really wanted, and changes his mind, it is just a software change.
[20:28:41] <cradek> yeah that's sure a lucky situation when it happens
[20:28:55] <andypugh> For example, this bucket-gauge probably wants to give the answer in inches.
[20:28:56] <cradek> same if I'm the customer myself
[20:29:09] <Tom_itx> and the cost of C's nowdays it's cheaper alot of the time

[20:30:49] <andypugh> I designed a trip-cock tester for London Underground. We dicided to go with simple electrics, DIN-rail timers, relays etc. In the end it cost a lot more than a PC and monitor woud have done, and then when they discovered that their Victorian test spec was _stupid_ it was impossible to reconfigure it.

[20:33:07] <andypugh> One part of the test-spec was to apply 100psi to the opened valve to ensure that it didn't get blown closed, This was a 1.25" valve. We had the stupid situation where my 20,000 cuft/hr piping (4" diameter) and vast regulator was hooked up in the same place as their old tester, to a 3/4" air main.

[20:34:50] <cradek> haha, wireless
[20:35:07] <andypugh> cradek: My machine could flow enough air for there to be 100psi pressure drop across the valve.
[20:35:12] <cradek> wow
[20:35:27] <andypugh> Which is clearly what the test was _meant_ to be about.

[20:36:32] <andypugh> They just had never realised that that meant a 2000hp compressor. And I was young, inexperiened, and just assumed that they must have the required air supply as they had been running the test for 100 years.

[20:59:49] <chopper79> Hello, Does anyone have any information about JA3 fir Linuxcnc? I need to give this a shot instead of using gantrykins.
[21:00:13] <cradek> hey
[21:00:27] <cradek> do you have a more specific question?
[21:00:38] <cradek> are you asking how to build it?
[21:02:22] <chopper79> Gantrykins handles a tandem axis very poorly and I need to be able to auto-square the tandem axis with ease. Also I have heard that the JA3 branch has fixed a lot of the known issues with gantrykins. I need some advice on how to go about using the JA3 fix for my machine.
[21:02:56] <cradek> so the precise thing you are trying to accomplish is auto squaring?
[21:03:34] <chopper79> Yes, in a nut shell
[21:04:49] <cradek> I am not a fan of gantrykins and I would attempt autosquaring by getting into the guts of the homing process at the hal level. are you squaring to switches or encoder index?
[21:05:10] <chopper79> Auto squaring when homing and the keeping joint mode hidden. All I should see is world mode when using the machine. I have gantrykins running now but it a painful process keeping or making it work reliably. I figured I would give JA3 a shot.
[21:05:13] <cradek> or hard stops?
[21:05:14] <chopper79> Switches
[21:05:25] <chopper79> Swithes hitting hard stops
[21:05:26] <cradek> do you have encoder feedback, or open loop?
[21:05:31] <chopper79> open
[21:06:13] <chopper79> I can do it using a parallel port and trivkins no problem. I am trying out a MESA board and would liek to use a kins module instead of gates as I do now.
[21:06:15] <cradek> I'd use basic old trivkins. use a very low velocity for your last homing move so you don't need acceleration control. then mask the step pulses to the switch that's not hit yet.
[21:06:53] <cradek> why do you want to change that?
[21:07:17] <cradek> mesa vs software stepgen is not important here, let's talk just about homing
[21:07:52] <PCW> That's the issue, it not practical to gate step pulses with the hardware stepgen
[21:07:54] <chopper79> I do not have eyes on the stepgen using the hostmot like I do parallel.
[21:08:22] <cradek> oh I see, you were using internal (hal) gates
[21:08:34] <chopper79> correct
[21:08:48] <chopper79> So I figured this JA3 fix would potentially do the trick
[21:09:07] <cradek> well you're adding a lot of complexity and unknowns
[21:09:21] <cradek> by all means try it, I guess
[21:09:24] <chopper79> True, but gantrykins kinda does the same
[21:09:35] <chopper79> the complexity and issues I mean
[21:09:39] <PCW> Michael G seems to think it fixes the issues and he's been using it for a long time
[21:10:13] <cradek> how does he autosquare?
[21:10:40] <cradek> I don't see how trivkins helps you autosquare but I may be missing something
[21:10:45] <cradek> err I meant gantrykins
[21:11:30] <cradek> do you just start the two joints homing at the same time and let them work separately?
[21:11:59] <PCW> [00:42:36] <micges> in ja3 there is gentrivkins that will hide gantryness
[21:12:01] <PCW> [00:43:10] <micges> it is trivkins with ability to map axes to joints
[21:12:03] <PCW> [00:43:39] <micges> with it it will never be in joint mode (no ability to move joint from gui)
[21:12:05] <PCW> [00:44:25] <PCW> how does that help gantry homing?
[21:12:06] <PCW> [00:44:33] <andypugh> But homing is a joint-thing not an axis thing?
[21:12:08] <PCW> [00:44:57] <PCW> Oh I see joints for homing only
[21:12:09] <PCW> [00:45:23] <micges> yes
[21:12:11] <PCW> [00:45:34] <micges> just home all button
[21:12:12] <PCW> [00:45:49] <PCW> does that work now?
[21:12:14] <PCW> [00:46:18] <micges> it was 1.5 year ago iirc
[21:12:20] <cradek> (if ja3 really works we oughta merge it)
[21:12:22] <chopper79> They have the same home seq. and then after homing/squaring is doen you have to switch to world mode and then gantrykins slaves the Y and A or the axis you slaved.
[21:12:25] <cradek> oh it's NOT gantrykins as we know it
[21:12:44] <cradek> that sounds interesting
[21:13:23] <cradek> chopper79: ok I understand (but you have a terminology error: it's never A)

[21:14:19] -!- jpk has quit [Ping timeout: 264 seconds]
[21:14:39] <PCW> I think a gantry homing comp could work but its not trivial
[21:14:57] <cradek> especially for index it would seem to get quite hairy
[21:15:15] <cradek> gantry support likely needs to be built into motion
[21:15:38] <PCW> Yes that would be best
[21:16:00] <andypugh> R2E4 If you have the room for the grinders, then there are some jobs that only they can do.
[21:16:09] <cradek> you really want more than independent approximately-simultaneous home sequences. you want each stage of homing to wait for both sides to sync up before the next stage starts
[21:16:11] <andypugh> Modifying bearings is one thing.
[21:16:20] -!- smithrobs has quit [Ping timeout: 252 seconds]
[21:16:29] <chopper79> Correct
[21:16:43] <cradek> so each stage improves the alignment, not just the last one
[21:17:08] <cradek> there is not currently an easy solution for this. I'm not sure there's a hard one except to go ahead and put it in the motion controller.
[21:17:10] <chopper79> I can do this with trivkins by gating the stepgen commands. It has always worked well and no issues.
[21:17:37] <cradek> you could pretty easily do the gateing in hardware
[21:17:52] <PCW> but that is so M^2L
[21:18:16] <cradek> pcw could (not so easily at all) add a step-pulse-gating input

[21:19:21] <cradek> but that's so far from the general solution we really want that it would be silly to do
[21:19:30] <PCW> violates accel/ violates steplength yuck
[21:19:35] <cradek> yep
[21:19:56] <cradek> everything is nasty about it except that it would probably work (like his current solution with software stepgen does)
[21:20:38] <cradek> you're simply not going to get aligned to one step pulse anyway. you need encoder index to get it perfectly square
[21:21:33] <chopper79> When I home my machine currently I will be within a .001 of an inch of square all the time everytime.
[21:22:11] <chopper79> Been that way for about 3 years now.
[21:22:13] <cradek> what is your overriding goal in changing away from this setup?
[21:22:33] <PCW> just need avoid accumulating errors
[21:22:44] <chopper79> Trying new stuff and I heard the MESA baords were the way to go for plasma
[21:23:43] <chopper79> Every config I have tried using a parallel port for plasma and THC, never works consistant.
[21:24:27] <chopper79> The Z axis is never compensated properly when making up/down moves to keep the voltage correct.
[21:25:25] <chopper79> So after a few minuts or less the tip of the torch is dragging on the material and the float switch will hit and trip and estop.
[21:25:31] <chopper79> Z axis walks I guess I shoudl say

[21:35:53] <andypugh> chopper79: The Mesa THC converts arc voltage to pulse frequency. You can actually count the pulses with a software encoder counter via the parport. But having an analogue signal to do "things' with is a big plus. For example you can cahnge the target voltage in software, on the fly.

[21:44:16] <andypugh> But section 2.2 is the relevant part.
[21:44:45] <chopper79> I have tried that before and failed
[21:44:56] <chopper79> I dont think my branch name was right
[21:46:55] <andypugh> 2.2 to 2.5 should leave you with a working LinuxCNC as a RIP (Run in Place) system. That means that your normal installation stays where it is, and that is what menu items and icons will open. But if you open a terminal, "cd linuxcnc-dev/ " then type ". ./scripts/rip-environment" and then "linuxcnc" you will run your freshly compiled version instead.
[21:49:09] <andypugh> The branch you want is probably called remotes/origin/joints_axes3
[21:49:34] <andypugh> But I would try building and running Master (the current dev version) first.
[21:50:17] <chopper79> The current master is version?
[21:50:32] <andypugh> 2.6 (sort of)
[21:50:35] <chopper79> At this moment I am running 2.5.0
[21:52:33] <chopper79> I need to type v2.6 and not v2.5 correct

[21:53:34] -!- FinboySlick has quit [Quit: Leaving.]
[21:56:03] <andypugh> No. Master is called master.
[21:56:54] <chopper79> git branch --track master_branch origin/master_branch
[21:57:05] <andypugh> The current branches that things get done in are called "master" and "v2.5_branch"
[21:57:37] <chopper79> so by leaving v2.5 I will get the master
[21:59:54] <andypugh> git is a big and complicated thing. There are more detailed instructions here: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Git
[22:00:03] <andypugh> But most of that is not likely to be relevant.
[22:01:10] <andypugh> If you install git, then clone the repository, you should be able to compile a version of linuxCNC that works. I suggest trying that first, and then worry about exactly which branch it is later :-)
[22:01:33] <chopper79> Just finihed the git and clone
[22:01:38] <chopper79> finished
[22:02:21] <andypugh> OK, if you cd to linuxcnc-dev and type "git branch" what does it say?
[22:02:52] <chopper79> master
[22:03:24] <DJ9DJ> gn8
[22:03:27] <andypugh> OK, try compiling that.
[22:03:33] <andypugh> cd src
[22:03:45] <andypugh> ./autogen.sh
[22:03:55] <andypugh> ./configure

[22:15:42] <chopper79> How do I launch this now to work in it?
[22:15:47] <chopper79> or am I not there yet
[22:16:06] <andypugh> You compiled master, and no errors?
[22:16:26] <chopper79> error... I need pythion
[22:16:31] <chopper79> python
[22:16:54] <chopper79> sorry
[22:17:16] <andypugh> I can never type python either. I always under-shoot and end up with pythin. Looks like you manage the mash both keys.

[22:17:35] <chopper79> wth...
[22:17:45] <chopper79> I did not type a icon
[22:18:03] <chopper79> :P
[22:18:06] <chopper79> that explains it
[22:18:13] <chopper79> : p
[22:18:37] <andypugh> sudo apt-get install libboost-python-dev
[22:19:36] <chopper79> done
[22:19:46] <andypugh> You have a fast PC!
[22:19:56] <andypugh> OK, run ./configure and make again
[22:20:27] <chopper79> done and no error

[22:27:02] <andypugh> skunkworks: So Spngledboy (a name I recognise from the forums) pops up to say how happy he is with LinuxCNC, and in a reply some dude says "well, I am going to go with the more expensive solution that no-one has ever tried"?
[22:30:26] <chopper79> Andy- Thank you and I will give this a go. I may need to call upon your expert advice later. Right now I need to go send some lead down range.
[22:30:47] <chopper79> I will get lost and tryt o dig myself out first.
[22:32:30] <chopper79> real quick anytie I want to make a change or run master I just needed to do it in terminal or can I launch it from the desktop ?
[22:35:03] <andypugh> It depends what you want to do. You can use ./configure --prefix /usr and that actually installs the compiled version over the top of your installed/released version. Or you can make an icon/shortcut to launch the run-in-place version.
[22:35:32] -!- stsydow has quit [Remote host closed the connection]
[22:35:57] <chopper79> ./scripts/rip-environment = no such directory
[22:36:27] <andypugh> I actually have the ./scripts/rip-environment in my .bashrc so I never need to type it. If I open a terminal, then I am automatically configured run-in-place. But that is just to suit me, and might not suit you.
[22:36:42] <andypugh> pwd ?
[22:36:54] <chopper79> no
[22:36:54] <andypugh> ie, where are you?
[22:37:03] <chopper79> src directory
[22:37:13] <chopper79> linuxcnc-dev/src
[22:37:17] <chopper79> $
[22:37:49] <andypugh> scripts is one level down. . ../scripts/rip-environenment from there
[22:38:10] <andypugh> that's dot space dot dot slash. It's like morse code.

[22:39:20] <chopper79> ok im lost now
[22:39:58] <chopper79> I typed ./scrpits/rip/rip-environment and no such directory
[22:40:10] <chopper79> do I cd to scrpits?
[22:40:33] <andypugh> the scripts directory is in linuxcnc-dev. two dots takes you down a level.
[22:40:33] <chopper79> or is it . ../
[22:40:44] <andypugh> cd to scripts is probably easier.
[22:41:04] <andypugh> then its just ./rip-environment
[22:41:36] -!- ravenlock has quit [Ping timeout: 264 seconds]
[22:41:52] <andypugh> the leading dot is some sort of safety thing. I think it makes it harder for hackers to inject commands.
[22:42:14] <chopper79> I can not chnage to that directory
[22:42:30] <chopper79> cd scripts
[22:42:34] <andypugh> where are you ? (pwd)
[22:43:01] <chopper79> I am under src still
[22:43:12] <andypugh> cd ..
[22:43:21] <andypugh> cd scripts
[22:43:44] <andypugh> . ./rip-enviroment (that's dot space dot slash)
[22:44:08] <andypugh> and it is spelt rip-environment
[22:44:26] <andypugh> but you can use tab to auto-complete after "rip"
[22:44:34] <Tom_itx> ok JT-Shop when you get this, i have a newer version of winavr you can install and it will compile for the attiny10 if you decide to use one of those
[22:44:45] <chopper79> ok that is done
[22:44:50] <Tom_itx> it's the version that comes packaged with studio 6
[22:45:01] <Tom_itx> atmel offers it as a standalone
[22:45:04] <chopper79> sorry Andy I am new to terminal and its commands
[22:45:28] <chopper79> little overwhelming
[22:46:07] <andypugh> yeah, it's all moderately novel to me too, so i do at least understand the issues.
[22:46:37] <andypugh> so, if you now type "linuxcnc" it ought to run, with a splash-screen that says 2.6
[22:46:51] <chopper79> well to me you are a pro
[22:47:29] <chopper79> it poped up config selector but no splash screen
[22:47:44] <andypugh> splash scrren is next, I think
[22:47:53] <andypugh> Choose a config
[22:47:57] <chopper79> yup... I had to pick a config
[22:48:01] <chopper79> 2.6 pre
[22:48:23] <andypugh> Congratultions, you just built LinuxCNC from source.
[22:48:30] <chopper79> Whoot
[22:48:47] <chopper79> Thanks I had a good couch
[22:48:55] <chopper79> lol
[22:49:21] <chopper79> coach
[22:49:46] <chopper79> so now when I make a config I can access all the extra?
[22:50:20] <andypugh> You now have the new stuff from Master, but that isn't the same new stuff as JA3
[22:50:47] <chopper79> oh
[22:50:53] <andypugh> JA3 is actually rather behind Master(2.6) but is different.
[22:51:25] <andypugh> Your configs won't work in JA3 without changes.
[22:51:36] <chopper79> I am all about changes
[22:51:49] <andypugh> i wanted to make sure you had a working setup first
[22:51:59] <chopper79> I do
[22:52:02] <chopper79> Thank you
[22:52:27] <andypugh> Firstly I would suggest making a copy of your complete working config (ie, the whole folder)

[22:53:23] <andypugh> Then rename the folder and the INI file something like "gantry_ja3" or similar. The INI file name is what you see in the config picker, in case you hadn't spotted that.
[22:53:26] <chopper79> At this moment I do need to go so I will read some more tonight and have a go at it this weekend. IS there a way for me to make actual changes to linuxcnc such as my own version complied with my own configs? Just a quaestion.... not going to as I could not even go back one directory
[22:54:00] <andypugh> Yes, now that you have the source, you can make absolutely any changes you want.
[22:54:14] <chopper79> wow
[22:54:24] <chopper79> just have to know whrre to go I guess
[22:54:26] <chopper79> where
[22:54:52] <andypugh> Exactly, that's the hard part. You can call every HAL pin "Tarquin" now if you want. It wouldn't help, but you could.
[22:55:27] <chopper79> all through terminal or is there a interface to work in?
[22:56:13] <andypugh> Hardcore coders use vi or a basic text-editor.
[22:56:13] -!- vladimirek [vladimirek!~vladimire@95.105.250.72] has joined #linuxcnc
[22:56:51] <andypugh> For what you want to do, you probably don't need to edit the code, just check-out the ja3 branch and compile it as it is.
[22:57:00] <chopper79> I would use gedit if I did
[22:57:17] <chopper79> so to get the JA3 branch I need to go throught the same thing as I just did
[22:57:56] <andypugh> if you do find you want to make more extensive changes then I quite like Anjuta when I tried it. Though I actually do my LinuxCNC coding on a Mac using XCode. (But I am the only one)

[22:59:39] <chopper79> ok... I have to go anyway
