command position with -inf, speed will -inf, likewise accell, etc
er, why not just stop?
because it's not exciting enough?
everyone can stop..
* alex_joni_ can't :D
heh.. software engineering: http://software.silicon.com/os/0,39024651,39152715,00.htm
woo, fixed the nan stuff
cradek: you're too quick..
if you keep the pace it'll be finished this year
there's no accel or stop yet - it just plows along at the requested velocity no matter what
I opened up my following limits pretty wide
huh.. no accel? :D
oh I'm sure there's lots of it
you mean infinite accell
in theory at least
actually stepgen might be limiting it, I'm not sure
should work ti the limits of mechanical structure... cool... then turn it bac 1 notch
dmess: sometimes it's too late to do that
gotta make smoke to find the limits folks ... HAPPY NEW YEAR...
dmess: Happy new year
hows the weather lookin for the turning of the new year in your locales
dmess: the year already turned here
the leap second is in place
and weather is cold, which makes the snow stay in place .)
what time there??
we just got some new snow last nite
hrmm.. can't update time from time.nist.gov
so it looks white at least
it says peer not synchronized
darn, I missed the leap second
you'll get a fresh one in summer
my sons all perplexed by a leap second concept
but he figures there should be more than 2 per yr to make up a day after 4 yrs
hes his MOTHERS child... the smart one... ; )
LOL, I updated my clock from time.windows.com, as time.nist.gov barfed
and it is 1 second behind :D
how can you tell?
I compared it to a linux pc which could ntpdate
oh wait, it's the other way around
your loking for the second.... im looking for the inch...
or the millimeter
some people add a "leap-kilo" every six months
or even faster
this new job made me add odds and evens KILO in the last 6 mo.
i was only this heavy when i was wrestling at age 19
dmess: so you can say you're just like you were when you were 19
kinda i guess... not working in a mine now though...
my knees were still good then too
dmess: we're all getting older
that's better than the alternative
and that's not enough.. others are adding extra seconds to our age :D
i dont like to believe in time.... only in tomorrow...
cradek: which is.. ?
today maay be it.. live you life guys... do what you want to do... and enjoy the smiles along the way..
dmess: and never look back ;)
or regret anything
remember the smilin' times... for they are what you do it for
regret is a bad decision ..leading to a lost option
i resolve to be perfect, forever
if you TRY.. its a start...
it's all a matter of picking your goals
once you perform a while.. YOU EXPECT it
the alternative ISNT an option
DO YOUR BEST.... the old cub scout moto
& BE PREPARED ... the old scout moto
hope for the best and expect the worste... anything in between we can deal with
have low expectations, then you'll be happy all the time :D
because you'll always have exceeded your expectations .)
alex_joni: that's what I was saying, but dmess didnt get it
actually life is a fragile balancing act
i did... i just shoot for the stars... once i got the moon... that was cool
but your right if you never try you never fail
Greetings from 2006 ;)
cradek: still around chris?
5 hours to midnight
skunkworks: and counting :D
whats it like in the future?
except for my laptop screen it's all dark
that doesn't sound good ;)
so the future is bright only in here :D
happy new year alex
same to you les
well the new year means getting back to work on the research projects
I took off a couple weeks because everyone else did
ha #newyears is crazy
it's ok, only kiddies today :(
Note the left column "Popular Searches" http://people.howstuffworks.com/becoming-a-doctor.htm
Jymmm: bounty hunting?
doctor, bounty hunter, same diff
and witchcraft :P
it was all the dark stuff that got my attention.
halloween, tarot, witchcraft, creationism.... people "searching" for somethign to believe in.
and dont forget modern medicine
thats not in the list
finished my camera webpage :D

The real reward, he says, is the adrenaline rush that comes from making an arrest. Burton refers to it as "adrenadollars" -- "For every buck we make arresting someone, we make $1,000 in adrenadollars."

this guy has the biggest mullet i've ever seen
what's a mullet?
alex_joni hair style from the 80's
i knew you'd ask that
alex_joni long in the back, short everywhere else.
favorite hair style of rednecks
also a fish I like to catch
fenn: not my fault I'm not native to those awkward expressions :D
lol @ les_w
alex_joni watch MTV
Jymmm: I would.. but they took it away :(((
now it's MTV romania, and it SUX big time
my christmas present to myself http://www.photoflex.com/photoflex/index.html
what did you get?
a lighting backdrop?
damn frames... http://www.photoflex.com/photoflex/index.html?products/default.asp?product=shoemount&1
there are some other kits at the bottom :)
Jymmm: you could have made that
if you say so..
blah. No new year parties. Why? No people here.
if you like it.. enjoy it
les_w: we said we'd come over
but you didn't say anything..
dmess: say again?
or was that all to it?
sorry that was the brainiac son... we're off to some friends to ring in the new year... bbl
* alex_joni_ will probably be asleep
so Happy New YEARS
merci ... )
a plus tard
and too all. the best to you and yours... may all your dreams and asperatins ...not choke you..
hey chris.. almost midnight over there
2 more hours right?
no, only 20:20 here
I can't believe you're not asleep by now...
ahh.. ok, bad math this late ;)
only 4:20 here :D
night all, have a great 2006
did anyone observe the leap second?
I missed it...
but my clocks are off ntp by a second
presumably they will slew in ...
anyone using the 4.38 bdi? I am using the 4.3 - whats new?
I saw release notes somewhere...
I remember there's a new AXIS build
but you already have that of course
I might - (did a install on a new computer last week) - your site is on my favorites ;)
03cradek 07simple_tp * 10emc2/src/emc/kinematics/ (tc.c tc.h tp.c):
simple_tp is alive: run, abort, feed override, step, etc all working.
no accel yet. don't try this on a machine.
great work - shouldn't you be out celebrating?
nah, it's just another day
drinking wine with the wife and watching suzi orman
sho is suzi orman?
financial show. wife likes it - I almost can
can't stand her
suzi, or the wife?
that'll be fixed in English 2.0
right, I was kidding
we still have eggnog - maybe we'll have some at midnight
I think when I add accel this can be used in real life
good. I am not known for my spelling or punctuation
not sure it has any practical use
cool. alex seemed excited about what you are doing
I guess it will give correct results when the old tp gave bogus blending
axes with very different accels for instance
try it sometime :-P
I probably will.
I mean the old tp with very different accels
it's very bogus
well - my accelerations must not be too differnt for it to matter
5 vs 12
your fix really helped though - now I can run them different accels.
I tried 20 and .2 I think
you get a totally bogus trajectory
I know you said on multible axis moves the accelleration would be less than it should
I have not noticed it yet though.
that's right, it is
it would probably be hard to notice
you would have to set your [TRAJ] accel above 12 to get it anyway (if it worked)
[TRAJ] accel is the tool tip's accel, which can obviously be higher than any axis's accel
by sqrt(3) for 3 axes I think (0,0,0 to 1,1,1)
it seems like a good time to get into emc2 - lots of things happening.
yeah, lots of old bugs are getting weeded out, which is nice
right. - I really like axis also. I will say it again - nice job.
thanks, I really appreciate that
I've wanted to write that gui ever since I started using cnc
I'm glad Jeff and I were smart enough, together, to do it
;) - how did you meet jeff? wife like your cats ;) (I think they are yours)
one of my two is pictured on timeguy.com
if you're on unpy.net, those are probably jeff's cats
I've known jeff since ... junior high, I think
we're almost the same age and were in school together for a while
thats cool - I barley remember the people I knew in high school. It was a me generation. everyone did there own thing.
we actually went to different high schools
I read once that if you look at photos of parties you have had over the years, and they show the same people but getting older and older, you're doing something right
he's one of that kind of friend
that is great.
I can't say that. Other than my wife - my family is really the only "friends" I have. Other than online I don't know anyone that has the interests I do.
that's a shame - it's true very few people are interested in the kinds of things we are.
many, many people spend all their time watching TV or buying trinkets at walmart...
I hear you.
as I sit here watching tv ;)
it's interesting that free software can sometimes pull the do-ers together
some TV is ok - only TV is not.
I am not as good a programmer as I wish. lately it has been access for work aplication. db
I hear access is pretty bad...
yah - it gets the job done for cheap though
fwiw I don't think of myself as a programmer either, but I can program when I put my mind to it
you're probably the same I bet
if I put my mind to it I can fumble through a lot. (writen some pretty wicked stuff when I needed to)
I actually looked at some of the interp stuff - but I would need a few weeks to get used to it.
that's because it was written by rabid monkeys or something
I've never seen stranger C
it has been a while since I have had to worry about lib
what do you mean libs?
compiling/linking and all that comes with it is something you have to learn on top of C
but for making small changes you usually don't have to mess with that much
if you have questions ask!
well - I think the wine is getting to me. I will end this now before I start mumbling. (if I haven't already)

RifRaf_ is now known as RifRaf
I have a question: why Linux?
RifRaf_ is now known as RifRaf
t4: because we can
oh poop he left
Happy New Year !
Got one of those dumb questions...
happy new year
In windows a .bat file just works...
In Linux how does one get a script file to execute >??????????????????
Happy New Year !
damn - for a second I thought it was going to be a microsoft question.
If you type in the script file name it just says command not found...
Well...windows is so straightforward to use...I hardly ever get stuck for an hour on something like this...
;) glad I am not the only one. I am not used to linux yet.
In Linux, well, I have spent tens of hours on such simple stuff....I think they call it "tribal knowledge" that unless you have worked in a Unix/Linux organisation you just do not get...
And I live in Naperville, IL, with one of the highest number of UNIX programmers in the USA !!!
But have never worked there...or anywhere where Unix is used...
Trying to mess around with Dean Hedlins NCUTILS ...
we have a bunch of macs at work and that would be the closest. I only am involved when they are stumped.
I just did some looking on the debian web pages for "how to run a script" and there was all this stuff that came back on using scripts to do something...
But I could not find anything on how to actually get one of these things to actually execute...
I guess when it comes to just getting things done, its hard to beat Lab-View....it autocompiles as you write it....
;) emc2 is run by script - that is run sudo. sudo scripts/emc.run
but when I goofed around making it a "shortcut" (microsoft terms) I could not get it to work
I tried sudo demo (name of the scripts is demo.sh) ...
(didn't try too hard though)
tried demo ,,,,, run demo run demo.sh demo.sh others I m sure...
Tried runing the command form a K window....
Running the file, that is...
wb9mjn: did you make it executable?
ls -l demo.sh
make sure the x permission bit is on
otherwise, chmod +x demo.sh
then run it: ./demo.sh
Figured it out....had to type bash demo.sh
Then found two errors in the script itself...
One error was there were two -i <filnames> in a command, when there shuold have been a -i and a -o for input and output...
Then the other I m pretty sure was a type, a -z in place of a -s ....
The make install does not work in that stuff ( /usr/local/emc/src/ncutils ) either, but it was easy enough to copy the bin files to /usr/local/bin and /usr/local/emc/src/ncutils/bins2go ...
Had previously tried sh demo , and logged back in as root ....
As I could not copy the files where they needed to go as a user even with sudo ...
you do not have to type bash demo.sh - that may work if the file is not set executable properly
Which I needed to do to as the demo.sh script reads the files from those locations...
my advice above is correct
Welp, the bash demo.sh worked...Did not see your advice while I was in the other room...
Wish there was a way to permanently set the file browser so it lists things by text...as the iconic representations in KDE are too incomplete in the information they convey...
don't know anything about file browsers, sorry
djb_rh_ is now known as djb_rh
The file was set to be an executable already....They could put a little X up in the corner of the icon to indicate executable is set...although the gears and shell icons are supposed to be
./ is the kinda tribal knowledge that gets me in trouble all the time with Linux....
If the executable bit is set, why not just execute when the file name is typed in ?
wb9mjn: Because "." is not listed in $PATH by default.
imagine that you are in /home/eviluser, and he's created an executable in that directory called "sl", which removes all the files in your home directory. When you type "sl" instead of "ls", it executes.
Also messing around with TTT, that s next...hi...
What is FT_New_Face ?
FT_New_Face is one of the APIs of the freetype library. It's the one that opens a ttf file and lets the program do subsequent operations like finding out the shape of a particular letter
if you get this error, it probably means you need to specify a ttf file on the commandline: Fatal error in FT_New_Face: cannot open resource (1)
When I run TTT it says it cannot be found...yep..that s the fatal error I see..
heating up the room here with a c:/search....
there are plenty of free but terrible ttf fonts on the net. http://www.webpagepublicity.com/free-fonts.html
Freefont 2 was apparently included in the rc_46 distribution of EMC...there are allot of fonts in /usr/share/fonts/truetype/freefont/
And its listed by the package manager...
So I have to pick one ahead of opening the program ?
you name the font on the commandline
$ ./ttt -?
./ttt [-?] [-f /some/file.ttf] 'The Text'
Does 'The Text' have to be enclosed in quotes on the command line ?
Double or single quotes ?
well, if it includes whitespace
these are all equivalent: 'The Text' The\ Text "The Text"
Ok....got a big g code listing in test out...
it's the shell that interprets the quoting, not ttt.
use shell redirection to store the gcode to a file
./ttt ... 'The Text' > thetext.ngc
Or cut and paste...
But then one gets snagged by directory permissions again....
03rayhenry * 10emc2/scripts/emc.in: sudo emcsh to prevent error messages on shutdown.
Happy New Year Ray...
Thank you. To you also.
Messing around with the ttt program and the ncutils....and being generally grumpy....
I should really get a whole night's sleep....
to much fun?
Its cradek and jeplers True Type Text program...
Seems to work....
We are getting sun now, for the first time in about a week....
BTW, this is right from the machine console...
oh it's mostly cradek's program
[17:12:48] <jepler> http://timeguy.com/cradek/truetype
I only contributed one or two tiny things
Its not as pretty as the other one I ve tried, but it puts the variables right up front in the G code, so one can tune in the result faster...
That is, it does not have a GUI...
it's way too simple a program to need a gui
The comments that describe the variables should be more descriptive.....(SM - Retract Height) ( CUT Depth in units) (FEED in units/min) ...
Just commenting that other people have done GUI's, but it doesn t matter here, mostly because the scale stuff is in there....
Oh and (SCALE of X and Y ) ...
FEED could be in mm/second
it'd be nice if there was a note giving the bounding box
Yes, but one can figure that out pretty quick, as it goes left to right...just scroll down to the bottom of the text and multiply the last X by the scale...
or load it into a recent cvs version of axis and read it off the screen
Have not got AXIS installed here yet...I guess there is an issue with the old kernels ( I am using RC_46) ...
we don't currently run or test on rc46
I ll upgrade eventually...
Still have some mechanical and electrical to get right here yet...
Hot Z servo motor !
Going to 3:1 drive, some sort of lifting spring, fans on the motor......
counterbalance spring, that is...
wb9mjn: You might ddt the command on that axis and tune to minimize the rate of change
This is emc2?
No...it s fine when its moving...it overheats when its holding....
No, emc1 ...
Oh. Then I'd say put your ear to it and reduce P and D until it quiets down.
ddt is an emc2 thing.
Another part of the problem is the original designer set the belt stretch at .030 inchs, which is allot of bearing side load...
Its a heavy milling head, and until it drops a little, it wont support its own wieght...it backdrives the ball screw...
So, when its in operation, it lifts the milling head ...even when the head is commanded stationary...
about 1 amp quiesent...
After a few hours of that, the motor is very hot...
Even with retuned PID , it would still lift the milling head....
By going to the 3:1 drive, it ll drop the static torque requirmenets of the motor by 2/3 s...
And still be able to do the 240 inches / minute....I hope...
The 2:1 drive peaks out at a 270 in per min at 36 volts...but it cannot go that fast in reality...current is too much...
So, going to 3:1 with 48 volts, the motor will spin up faster to be able to do the 240, still, but with less current, moving and static..
The smithy 1240 has a heavy head also.
And, I will also correct the belt tension issue, and relocate the encoder...which were other goals...
How big is the motor ?
about 240 lb so I used a gas spring to balance.
I want to get the good encoder directly on the Z shaft anyway...Its a matter of just picking the new pulley ratios for the spacing and
This head is about 50 lbs, and the motor has 360 in/oz peak, 42 stall continuous...Its a brushed DC , if it was brushless, it could probably
do this job no problem....
The motor is 2.3 inches by 5 inches....
Les says its probably fine when moving, as there is air circulation in the motor then....
I ran chips-3D the other week, took about 1/2 hour...motor was just barely warm to the touch...
Holding Z static for 2 hours, and its up above boiling water....
There is some torque ripple in the ball screw.....
And the belt overstretch issue too....its all adding up....
Mechanical things tend to do that.
Yea...electrical too....I get nominal 50 Return Loss connector designs on paper...by the time the tolerances are all in there, lucky to make 30...
Have confirmed the paper design work against precision models and they are a dead match...
But when you need to make things small...its more challenging...
Some of these MXL pulleys vary by a few thou in the OD....That s why I had to add the idler to the Y drive...
The original pulleys did not skip...but the custom pulley/encoder shaft , the stock was a little smaller....
I bored some of those pulleys out and had a bitch of a time.
Just enough to do the skip....

what's to laugh about?
Well, this is unique enough, and from what I remember not bad tasting, so seems like a good thing to have on the shelf.
laughing as your found what you wanted, and I'm still looking after 5 years
well.. it was the same country
that makes it a bit easier
and I had a telephone number on the label which I called
yet they didn't deliver anymore to my area, so I traveled about 600 km to get some :D
and the funny thing was: it wasn't even as good at the first I liked :)
probably gonna be the case here too.

it was about 2$ parts :)
I am still searching for a diving compressor
seem hard to find high pressure compressors
well, at a sane price.
how much is high pressure?
get a coating pump
but works with fluid..
air motor, fluid for pressure
goes up to 520 bar
gear pump I guess?
dont htink that will work for air ..
no, but you can pump liquid in a tank, and have air pressurized
but it really depends on your idea of cheap :D
[23:41:39] <alex_joni_> http://www.robcon.ro/ro/prod/81/Tiger_72-300.html
