i'd rather a true DOS system than ANY WINBlows boot screen...
bcz when the h/w pukes and you discover it a strange celeron processor that was only made for 3 weeks... you wait 3 1 month for a CPU and 2 more to load the s/w and check out the machine.... TOSHIBA... in 6 hrs ive scabed a board from the show room and your up and running with the last brain i scabbed from ya
our new FIDIA is a winblows front end with a pci micro-processor doing the real time stuff on its own

i have stpid Q and need help: i am trying to +grade to 2.2.5 on ubuntu6, but when i run the shell script, i can only get version 2.0.5, which was on the original live-CD i used. any help out there?
emc2.2.5 needed i meant.
hmm--now this is one i had not seen. i read several other similar wiki docs, i will try this. thanks!
welcome, hope you get it.
Hello - Im trying to setup a DRO with pyVCP to read an acu-rite linear scale, this one: http://www.acu-rite.com/act_Download.cfm?FileID=220&/AR5scale.pdf
sorry - my laptop stalled - did anyone here my opening question about a DRO
I didn't see a question
can the lpt port source enough current to run a linear scale - the manual says max 200mA
I didn't think so - I will setup a separate power supply then - thanks
can someone tell me how to do a simple thing like rename a directory in cvs?
officially, you can't
unofficially, you have to muck with the repo
thanks- so I'll have to email sourceforge?
to get them to change it I suppose?
why do you want to rename it?
you need to keep history or?
well, it's one of those things that happened early on, and the original name made no sense- so I changed it- little did I know...
mucking with the cvs repository directly is a bad idea. cvs doesn't support renaming, and it's best not to try these "tricks" to rename.
cvs rm the file in the old location and cvs add the new location
that looses history for the contents
use the -P (prune empty directories) flag to co and up so you don't get empty directories
ds2: yes, but the alternative is bad too -- it creates a false history
joys of cvs :)
use git ;)
if you check out old revisions or dates, you don't get the same thing that was actually checked in at that revision or date, because the locations of files are different
maybe I'll just forget the whole thing, and call it a lesson learned.
yeah, almost every revision control system newer than cvs has tackled this issue one way or another
[04:07:49] <jepler> http://www.eyrie.org/~eagle/notes/cvs/renaming-files.html
another fun thing - CVS doesn't "understand" directories
if you have realised early enough in your project's history that cvs is no good, then hurry and import the repository into a newer system -- I think that svn, git, and bzr can all import cvs pretty OK. then never look back.,
"early enough" depends on how many developers you piss off because they have to learn new tools
well, that's not too much of a problem here I guess, I'd just piss off myself mostly:)
trouble is, it doesn't encourage experimenting- not on something so important.
does svn offer the concept of a change list?

too much beer at the fest last night!
Jepler is up :)
jepler: good morning.
my last day of work today.. :) (just giving you guys a heads up)
so you're driving down tomorrow?
probably won't be down there until late.. (like 8:00 or so)
just in time for dinner
heh - you guys eat late.
heh - is your sleep schedule new? or where you always 'early to bed...'
do you have a video camera or a digital camera that is any good for videos? by the end of the week we'll want to record a video of max5 milling but I don't think we have a good camera on hand yet
compared to cradek, swpadnos, and jmkasunich I'm an early riser
compared to ray, I'm not
I have my acceptable (fixed focus but seems to work for youtube) camera
oh in that case we're covered
[13:38:22] <jepler> http://www.youtube.com/watch?v=_tA-W7nTNSc
what have you fellas been focused on at the fest so far? hard to get a grip on the IRC
als: all sorts of stuff is going on
ray henry is teaching a series of classes on linux and emc2
we're doing some demos of lathe and mill with emc, including the new 5-axis milling stuff
talking to people about the software
getting the emc2 mazak ready to mill a motor mount later in the week
cool keep us updated if you would
jepler: we might have a minidv camera. we will look.
skunkworks_: ok but it sounds like cradek has something that will work too
ok - cool
hm interesting -- I am running 4 instances of pov on my dual-core laptop. sometimes each one gets about 50% CPU, but other times one gets 100% CPU and the other three each get 33% CPU.
That video is pretty cool :)
I'm glad you enjoyed it
How long did that take to render?
most of the day
actually I let it run overnight
hmm just watched, I like
* archivist hopes/waits for same in axis window
people prefer their axis backplot to update more than once every 3 minutes
go on you know you can do it
I think there are possibilities, Im certainly not looking for ray traced perfection
jepler had started something a while back..
[14:27:17] <skunkworks_> http://axis.unpythonic.net/01169689661
hmm I should start playing wit the axis code more
for me when rotating the A axis the tool should not rotate, but the blank should
and the paths....
leaving cuts in the gear
cradek: good morning :)
seems people are interested in your max :) usually groups of people standing around it
it's definitely unusual
btw - how has the temperature been?
it's nice and cool
high 75 maybe
Great. It has been beautiful here also.
64 here in dayton, ohio
sposed to be in the 50's tonight
50's and night and 70's during the day
my garden really likes the 70-80 degree weather...
1" hall here yesterday my garden didn't like that
what ya growing alSMT?
nice... i got all that going -broc, squash, onions
big mamma lima beans from burpee... sposed to be like ten feet tall
jepler: is this the shuttle express that doesn't seem to work with the linux kernel? http://www.cnczone.com/forums/showthread.php?t=59800
hey would the transformer from the power supply of an old(newish) JVC tuner work for part of the pwoer supply for my HobbyCNC 4 axis board?
i was thinking it would work..* just haven't got around to building something..
for logic maybe, stepper driving unlikely
i was slavaging some caps out of the thing and i saw the transformer and got inspired to finish the hobby cnc board... it's been sitting here half soldered on my bench for like a year.. :|
i think i am at the point where i set the voltage and test... then solder the driver chips in
* chr0n1c really really wants to get an A axis going
jymm, you still op in ##php
well, now that the head on my Bridgeport is trammed I can get back to work
my bridgeport hasn't fell from the sky and landed in my garage yet... still waiting
don't wait in the garage
* BigJohnT though archivist would catch that
and run away with it
you would think with three stop buttons counting the e-stop that I would be faster than 200IPM rapid with 4 inches of travel!
needed an op earlier add cythrawl
or someone sensible
cam awesomeness = win98 in vmware on a x86_64 1.6ghz/1gbram
skunkworks_: probably, yes
what's up at fest today?
awallin: rigid tapping on the mazak is much better after tweaking inifile settings (task, traj periods)
ok, did you run the 5-axis program that was shown as an avi yesterday?
awallin: there's a lag between spindle and Z, and the sign of the difference is different in each direction
awallin: but changing it from traj 10ms / servo 1ms to traj .5ms / servo .5ms improved it by a factor of 20
awallin: yes we have milled it, but I don't think any photos are online.
awallin: the video finshed and made it onto youtube: http://www.youtube.com/watch?v=_tA-W7nTNSc
what was the diffence in actuall position between forware and reverse? like .005" (if that question made sense)
is the g-code CAM generated or generated by hand or through some ball-specific code?
is that Stuart in front of the Mazak?
DanielFalck: yeah, in thestriped shirt
I think the fest cam has crashed cradek has not moved in a hr or two!
jmk is out of irc.. I think the cam is hooked to his computer
yeah the camera driver crashes his computer once a day or so
much rather believe he is meditating ;)
are both Mazaks in the festcam being controlled with EMC2?
just the right one
what's controlling the one on the left?
we hear the left one works with the original control, but I think none of us have seen it
a couple years ago I saw it jog
afaik it has never run a part program since it arrived in this building
did you guys get the motor mounts done? or setup
alSMT: most of what you see going on around the mazak is related to the motor mount project
roland spent the last few days building a fixture in the other shop
its being mounted and assembled now
how is Roland doing?
pretty good I think
he's wearing the t-shirt with the heart on the back
its from the heart attack rehab place
working on preview and backplot for 5-axis http://emergent.unpy.net/index.cgi-files/sandbox/5axis-preview-backplot.png
that's an XYZBCUVW program
(the same one in the solids video I linked to earlier)
what was the vid link?
that is a sexy program
That is understandable.. What would it look like normally in the preview?
skunkworks_: mostly it looks like some vertical lines, because BCUVW are ignored
ah - ok
awesome, gcode from povray.. which does 3d dxf right?
whoa! did somebody make spherical interpolation?
[20:58:46] <chr0n1c> http://www.youtube.com/watch?v=mxxdq6y8z8M&NR=1
<- i just found this... wish i had sound
i know i had found one ray program that imports/exports 3d models in dxf now i can't find it anymore
tom1: I *think* that the move along the sphere is a long move in C but I'm not sure of the details -- I don't think it's applicable to non-5-axis machines
chr0n1c: jmkasunich wrote a special-purpose C program that ouputs pov code and gcode, I just changed it a little to make it an animation
chr0n1c: so it's not pov -> gcode, it's program -> gcode and program -> pov
who is the man with long black hair ?
that's steven tyler
oh, nevermind that
if you wanna see some emc in action, look at the emc2 tag on youtube... amazing...
I'm on the left. there's another guy with long black hair who is usually hidden from the camera -- that's SWPLinux
jepler: thx, did the spherical move go 'direct' to hal? ( no gcode, no ncg274 interpreter ?)
its really a cool animation :)
tom1: it's a gcode program
tom1: they are acutally cutting that on cradek's machine
jepler: with blue tshirt ?
micges: It's a grey shirt but the white balance of the camera is not very good..
the gcode is close to this: http://emergent.unpy.net/index.cgi-files/sandbox/trefoil.ngc
wah! i gotta work and the boss just gave me a 'be in detroit saturday morning'! crap!
tom1: enjoy your trip :-P
jepler: what is main subject on fest? how is the progress of topics that youre planned to do ?
ah! a bazillion short lines! np. the APT isnt popluar becuz people f\dont understand it , but, it can be told to cut the path into x size chunks, and will output such code for you.
micges: there are a lot of different subjects going on -- everyone has his own ideas.
thats how i did the xyz abc uvw hole driller with orbiting, lotsa short segments, and for me, just trivkins
micges: a lot of work today is going on preparing the mazak to mill a part for another CNC machine (a motor mount)
micges: another hot topic is the 5-axis stuff, and that's what I've been coding for today
there's also a lot of socializing and talking about the software (not everyone here is an emc user -- non-Free Windows controls for hobbyists are represented, such as mach)
also some cam software vendors (again, for Windows)
if you get the chance thell them we want open source cam...
I think the way to get open source cam is to write it
jepler: why preview of rotating is limited to only A axis ?
in emc 2.2 of course
micges: no, it's not a bug. in emc 2.2.x, preview and backplot basically ignore the rotational axes, and that is known and not likely to change.
even mastercam is talked about here ;)
(backplot does rotate the cone based on "A", but that's basically useless)
I'm working on improving that in 2.3, but exactly what that will do is up in the air.
my main interest is XYZBC like max5 but I will try not to foreclose other machine configurations
ds2 - you at the fest?
what is difference between xyzab and xyzbc ?
(I'm only programmer of xyz for now ;)
there's no practical difference except convention.
xyzbc tends to be a vertical mill or turn/mill, and xyzab tends to be a horizontal
note the tends, it's really however you want to set it up in the control.
what age is the youngest emc fest member ?
hey chr0n1c, how goes it?
good, alex_joni, thanks for asking...
... everything ok there/
chr0n1c: yeah, loads busy
(and it's close to 1am.. so I'm beat for today)

good night all

well that was weird, the ps2 mouse kept selecting the session and dragging its tab ( pigeon on ubuntu/emc2 8.04) , even 'tearing' it off to a separate window. changing to a usb mouse seems to have fixed it.
how did Ray's classes go?
DanielFalck: well, he says
today they did a tiny bit of hal from scratch (load parport, make some LEDs turn on and look at some switch states), among other things
I'll pass along the greeting
Hi DanielFalck Thanks for the thoughts.
hi rayh- wish I was there
That would be really great.
are there lots of people interested in EMC?
IMO the whole EMC2 bunch is doing great stuff.
are you training (indoctrinating) lots of newbies?
There is an amazing level of camaraderie among all of us.
any machine tool reps been around?? asking questions??
We have penguins at each entrance. Once inside they are infected.
boris probably would scare them off
I've got a dozen or so in the classes. I think things are going really well.
beautiful.... i love it when a plan comes together....
are the mach3 guys being friendly to the emc group?
as in friendly competition
even if its someone else's ... means it CAN happen.. again
a razor, right?
I think Brian from mach2/mach3 fame is there
i feel a need... a need for speed..... looks like in PEI bound this weekend...... pricey but i think i'll treat myself..... gotta look into it in the AM
