it's too damn early
anyone ever make a light tube?
how powerful is a 230 in.oz Shinano Kenshi nema 34 stepper motor?
about 230 oz-in
think it will lift the knee on a small mill?
with a big enough lever and a fulcrum you can move the world
torque*speed = power right? so wtf is up with units
units 230oz*in*1000rpm watt
17.343467 kg m radian / s
1 kg m^2 / s^3
[09:20:54] <sed> http://puga.mauibuilt.com/shop/DSCF0091.JPG
thats the mill
X to 1 pulley??
try and see?
lots of unknowns
what are the black plastic blobs on the red cart?
in the picture
in the back on the wall is a toe clamp kit and the cart on the side has a batery charger
and load tester
your motor is prolly about 170W
I could get some major Z travel on this litle mill if I could move the knee
based on 230*oz-in and 1000rpm
Im just picking through kits on ebay from other people who have done this
did you add the extender between the head and the column?
someday when I replace the screw in the table I can get 3 more inches travel on the dove tail on the knee
would be a good time to add a motor
lerman_ is now known as lerman
does everyone prety much gear down their stepper motors with pulley's?
well if you use a belt you dont need a coupler
and it's usually more compact
i've seen both ways
I kinda have to on the knee screw.. or figure a way to mount a motor on the moving end of the screw...
its kinda cool the knee handle has a release..
it would also be nice to couple to the Y axis with a motor that has a arbor on either side so I could mount the crank on it
hmm.. steppers and cranks
yea sounds like a bad idea
Is it really true that chlorine free bleach can be used to etch copper?
chlorine free implies what added?
I think its sodium persulfate.
fenn: You're at least missing a 'force' in the left-hand side of that units commandline.
fenn: units '230 oz in force 1000 / minute' watt -> 27.069...
I'm not sure what to do about rpm
maybe you want '230 oz in force 1000 2 pi / minute' watt
* giacus is pretty near to finish clean is room :(
dman it, trash everywhere
computers,electronics,robotics can't stay togheter all in one room !
need to invent a tardis
can't move a step in this room :/
1000 floppy disk, 200000 cdrom from 1994 to today
im putting all in a trash !
the only cdrom I'm using is debian netinstall
around 100 mb
best wishes to all womans :)
today is the national fest of the weoman here
there too ?
my fingers are going to become too bigger :P
I have to get smallest fingers

Has anyone here used chlorine free bleach to etch copper?
good morning :)
haven't had a chance to try the new iso yet
did you get some sleep?
got some mails, seems to work really good.. some issues with usbdrives... but nothing serious

hi, i'm trying to follow hal_intro, halcmd show all, doesnt show anything
have you started the HAL or realtime system?
nothing at all?
just headings and halcmd under components, no pins, signals, parameter or functions eventhough siggen and freqgen are insmodded
I have run realtime start and halcmd start
ok, so realtime is running, or halcmd would be giving an error
neither of those commands will load the modules
try running halcmd loadrt siggen
then halcmd show all
mike: how did you insmod siggen and freqgen?
do they show under lsmod?
previously i just insmodded them and they do show under lsmod
now i just rmmodded all modules, then did realtime restart and halcmd loadrt siggen
try removing them, and the use 'halcmd loadrt siggen'
does dmesg say something?
what params did you use to the loadrt?
halcmd loadrt siggen cfg=0,0,0
or something like that
halcmd loadrt siggen gives HAL:0: ERROR module not loaded but lsmod shows siggen
i gave no parameters to loadrt siggen
yes, the module gets loaded, but without any parameters it doesn't do anything
g0 is much faster the 120% reachable when doing manual controll. what was the tweak to make it a broader range... i know i asked a few months ago, i forgot
cncuser: you can define the feed_override in the ini, look for 1.2
ok, so 2.0 is 200
is there any reason not to increase that in the ini file? I use 2.0 or 3.0.
jepler: some might be concearned about accidental increasing from the GUI
mike: you should follow the examples in the hal_introduction
* jepler waves his hand
you didn't meet aunt tillie yet ;)
or didn't run your machine close to the edge, where moving the slider updates a few minutes later
speaking of tillie, halconfig can show what modules are loaded, what functions exist for each, and whether they are threaded.
it should show the siggen in the comp section
but there would be no pins / params / functs if there was n oconfig line, I think
... no config ...
it shouldn't even turn up under lsmod.. I think
alex_joni: a aunt silly mode could be deaktivateable, i think this pic should be on the button: http://www.pookey.co.uk/gallery2/d/1025-2/aunt_bessies.jpg
cncuser: yup, I think we can use that
id keep the size too :)
a bit larger might work too
true. the font is nearly unreadable
cncuser: oh shush
back to the basics, rebooted, realtime start, insmod siggen.ko, halcmd show comp
shows halcmd but not siggen
is this correct
is the siggen module actually loaded? (check dmesg and lsmod)
yes lsmod shows siggen
no errors in log
mike: why don't you try using some values?
loading the component by itself is not really usefull
by values you mean fp_period?
i used fp_period=1000000
sorry.. that's not for siggen
siggen has num_chan which is 1 by default
now I'm interested.. what OS are you running?
kernel / realtime patch / etc
if i add cfg=0 i get unknown symbol in module
yeah, sorry, that was my mistake
siggen should create one signal generator by default
mike: your build?
yes my build
ok, did you run rtai testsuite?
yes, but i'll recheck that
mostly the SHMEM stuff
[17:18:22] <cncuser> http://puppysit.hinternet.at/axisaunt.png
i like thegimp
cncuser: I appreciate the humor, but do you think there are things in axis that are too dumbed down for the sake of "aunts [a-z]illie"?
jepler: i havent used it much :)
SWPadnos: oops, yeah
just for the feedoverride ;)
what about the feed override?
the 120 ;)
oh -- but that's not axis' fault, that's the .ini files
but inis arent that muhc fun with gimp
cncuser: shall I mirror? or should I wait for it to get past beta stage?

do you remember latest discussion about plasma of cutter my cousin with robin_sz ?
I sayd can cut 4 cm ..
[17:51:16] <giacus> http://www.cemont.it/amministrazione/scheda_prodotto_en.php_idp=347&idcc=24&from=lista
it is :D
robin sayd no possible to cut 4 cm ..
I need a plane to build a cnc for him with that plasma cutter
Input power (max) KW 19,5
he use a bis power generator to run it
where is a good place to buy timing belts and pulley's?
McMaster Carr or Motion Industries are two that I use.
giacus is now known as giacus_afk
SWPadnos: my rtai testsuite runs okay
mike, I think SWP stepped out for a bit.
could you describe for me what you are trying to run?
mike, have you tried loading anything other than siggen?
try something like halcmd ladrt blocks ddt=1
oops - loadrt
Is it true that chlorine free bleach can be used to etch copper?
never heard that one before.
Does any one etch his own pcb:s?
Hi Guys! its been a while.
Most folks (I think) engrave/carve their own PCB's in here.
Hi Jymmm hows things?
Chaos, as usual =)
are any of thease places that sell CNC conversion kits a good start for use with EMC?
Jymm I feel for ya, things are pretty nuts here to.
Hmmm... I wonder if this could be converted to gcode...
x = (R+r)*cos(t) - (r+O)*cos(((R+r)/r)*t)
y = (R+r)*sin(t) - (r+O)*sin(((R+r)/r)*t)
It's the basis of a Spirograph (remember that from old-skool?)
It's beyond my math capabilities :)
Java --> http://www.wordsmith.org/~anu/java/spirograph.html
me too, but still...
Jymmm: it's simple parametrics - just write a loop over t
I would guess R and r are the radii of the two "wheels"
java source is available.
Jymmm: you could write it in terms of "O" words, but I'd rather write it in any other language instead
I don't care, I just thought you might not understand parametric equations
cradek: I don't =)
It looks pretty cool, it probably would be easy with a CadCam package.
jepler 'O' words?
Jymmm: it just means as you increment t, you can calculate the new x and y at each step.
Jymmm: so in this case, you'd increment t a little at a time, plug it into the equations that give you x and y, and draw lines between the points you get
Jymmm: it's a relatively new feature of the emc2 interpreter. There's a page about it on the wiki.
* bill2or3 wakes up.
remember on the spirograph it wasn't always clear when to stop drawing? Your program will have that problem too.
cradek: Well as a round shape on it's own not very useful, but as a border surrounding a rectangle it look like a certificate.
you need round certificates then (and a spirograph and pen)
There are ***MANY*** things mathamatical in regards to graphics I'd love to know.
Jymmm: what are some good values for R, r, and O?
you could store the start position and check to see if the current calc matches the stored position. that would be a start.
jepler 38 32 31 and revolutions 112
skunkworks: you'll probably miss with virtually any t increment you choose
jepler hit the RANDOM button to play easily
Jymmm: no java
thinking abou that :) that could be an issue but a starting point
Fixed Circle Radius 22, Moving circle radius 37, Movign Circle offset 48, Revolustions in radians: 259
cradek: couldn't hitting the start point mean 'stop' ?
[19:54:01] <jepler> http://emergent.unpy.net/index.cgi-files/sandbox/spiro.py http://emergent.unpy.net/index.cgi-files/sandbox/spiro.ngc.gz
Jymmm: yes, but since it's not continuous, you'll probably overstep your starting point.
Gawd you two are such geeks! lol
cradek: ah, ok.
I love it!
jepler: Silly question... If you have a 4"x6" rectangle, could it be made to follow that?
I assume you mean that as a compliment
Jymmm: it's a computer. of course it could.
cradek of course =)
cradek: I said 'geek' not 'nerd' =)
the number of times to go around is related to the ratio (R+r)/r
when t === 0 mod 2pi and (R+r)/r t === 0 mod 2pi, you're done
what's S ?
One of my goals in life is to know what every button on my calculator does =)
now how about a 3d spirograph....
Jymmm: well I got something interesting...
[20:05:46] <jepler> http://emergent.unpy.net/index.cgi-files/sandbox/spiro.py http://emergent.unpy.net/index.cgi-files/sandbox/spiro.ngc.gz
(different than earlier)
z could be a function of radius from center and it would make nice "flowers"
since the sin/cos are second order values, you can tell if you've reached the beginning by remembering what the position and its first 3 derivatives are. if they all match, then you're repeating
jepler: that's cool
that could be good for clock faces
SWPadnos: I was thinking sign borders if it could be to follow a rectangle outline.
the math is almost the same for that, I think
Jymmm: that new spiro.py does follow a rectangle
the equations there are for gearing to a round perimeter, but you can "roll" the inner gear along a rectangular path just as well
[20:12:06] <alex_joni> http://solaris.cs.utt.ro/emcstuff/spiral.png
cradek: that's not a bad testcase :)
I see many randomly generated picture frames in our future
looks like torture to me
no straight lines (or no curves) though
jepler why's that?
Jymmm: the acceleration graph is all spily
alex_joni: is one of those velocity? the bottom one?
but path is brilliant
that's not a bad acceleration graph
it's within limits
it's within constraints!
kinda rapid transitions though
er, a bad velocity graph
SWPadnos: the file is a lot of short segments
SWPadnos: there is no jerk limiting
SWPadnos: infinite jerk
now be nice
I think cradek is going to add sinusoidal profile this weekend
SWPadnos: no offence :)
the velocity graph changes (sort of) smoothly as the radius changes, that's good
giacus_afk is now known as giacus
I didn't take it personally ;)
only a few places where it jumps a bit
See ya guys later, have to do some work. Take care!
SWPadnos: knew you wouldn't
I'm running this file on emc1+sim and it seems like the cone is stopping all the time
veronica? how about k4ts?
alex_joni: veronic AND Anna ?
I know how to poly the veronica
I'm a raguler one man banned
Jymmm: now we can extort him :)
veronica is veronica
er, forget what I just said
one man banned?
veronica as quit :/
jepler: Ok, dumb me... what vars is it to set the rectangle?
Jymmm: It's hidden in the functions f() and y()
Jymmm: er, x() and y()
Jymmm: it's hardcoded for 4x6 (as the "center" of the path)
Jymmm: Look at the function x(). 't' goes from 0 to 1, so while t*20 goes from 0 to 6, so does x(). Then it stays at 6 until t*20 gets to 10 (y has gone from 0 to 4 in this time). Then x goes back to 0 and then y goes back to 0
It's t*20 because the perimeter of a 4x6 rectangle is 20 inches
Oh, so your considering it a circle (with staight edges)
you can write the functions x() and y() in any way you like
they're essentially another term added to the equations you originally showed
jepler: I dont know pythong, I could try it in php, I guess.
Jymmm: Any language you're comfortable with should be able to do this stuff
jepler: Yeah but I'm clueless on the math, it takes me a while to digest it all.
* Jymmm was too busy getting stoned in HS
Jymmm: I just took those equations as a given .. didn't have to understand them
jepler: I don't know trig, that's the problem.
anyone heard of Xylotex?
Jymmm: I bet you could change my program to do different sized rectangles without having to know trig
jepler: bet the end condition on the first spiral you posted can be improved
jepler: Yep, that's what I was thinking of doing, now that' you've written the foundation (which I apprecite very much)
Jymmm: use it in good health
sed: any other questions? =)
[20:26:35] <skunkworks> http://www.electronicsam.com/images/KandT/Screenshot-2.png
Hey, a JS variant might be nice.
somone on ebay is selling a Xylotex XS35V with 3 motors for $350, I was wondering if that would be a good starting point to work with EMC
rayh: A new cp1 MOP!
Jeff at xylotex changed filtering several times on these. It would pay to ask him if you can get the date the board was made.
LawrenceG, Really. You are trying to get that into emc2. Want to send it over?
sed: Jeff at Xylotex sells board, motors (new) and PS for about $400
all brand new
sed $350 all new http://www.xylotex.com/3AxSysKit.htm
Good thought Jymmm. Some of the old boards had real noise problems.
sed: the xylotex 3-axis kit is only $345 from http://www.xylotex.com/3AxSysKit.htm
rayh: I was looking at the spirograph picture frame border thatjepler did above as a new MOP
LawrenceG MOP ?
no shipping if you pay with paypal
Oh. That would be awesome.
MOP = machine operation? what say Ray?
sed: I like the motors (I have them), I wish I had Geckos though.
Damn he would ask. MOP is a machine operation. They are xml parameters that get expanded into gcode.
I am wanting to convert a small knee mill to CNC, I want to move the knee for the Z axis
for that matter, what's cp1
jepler: conversional programming
look for cpGui.tcl in emc1
It was a student project at NIST several years ago. Lawrence, Matt, and I wrote a bunch of them, some based on JonE c gcode generation routines.
oh some terrible^W gui for making g-code? That's not my cup of tea. I'd rather spit out Python code, as you can see.
Jym why Geckos? where do you get them from?
jepler: I would have to agree... that was my only tcl programming and it hurt a LOT
Gecko drives are overkill for the motors like this. Great product though.
I'll take full responsibility for the look and feel, but it was done during a very happy thanksgiving weekend.
I've never looked at the program so I shouldn't lead off by calling it terrible.
especially since I don't think I'm "the audience" for the program
jepler: CP1 == Conversational Polish 1
[20:37:34] <skunkworks> http://www.electronicsam.com/images/KandT/Screenshot-3.png
and no there is not stop when the thing closes up - yet ;)
it should have that spirograph feature where the wheel slips and you make an occasional nice tangent line
that brings back memories lol
or the ink dries up right in the middle!
then you have to get a new pen and figure out where you left off
and it should emulate thumb-tack holes in the paper
have not been able to break the lerman interp yet ;)
skunkworks: so your just brekaing out of it after so long?
[20:43:01] <Jymmm> http://mathworld.wolfram.com/Spirograph.html
I have t from .2 to 1000 in .2 steps
hey wait a sec... a pentagon? 1,5 ?
can you use "function pointers" in g-code? "o#1 call" to call the subroutine named by #1?
hey les_w :)
actully have not played with subs yet.
hi jacky and jymmm
I mean sam
seems like being able to write O#1 should naturally work but I'm not that familiar with the interpreter structure.
les_w: all right ?
yeah getting ready for chicago trip. Will be there a couple weeks
les_w: 0-15 days yet, and ill buy the motors
I have been watching chris' efforts on the tp with interest
I'll want to try it
but will need a new box
les_w: any progress with the toolchanger ?
I have been very busy with the latest invention.
Looks like this one is a go.
ehi rayh hi
les_w: inventionI what?
I was talking to dave about using HAL for factory automation
k4ts, Lawyers won't let me talk about it much. It burns fingers though.
I call it the finger burner as a working project name
les - will it fit in a breadbox? ;)
K4ts: we have stallman in 27 mar
K4ts: want invite les to the stallamn conference in catania ?
The trip is about that
i will go ..
in taormina :)
I was thinking if les_w ...
where is that
and what is stallman
yeah 27 marzo catania sicily island
les_w: its a great thing :P
les_w: to came ian italie
150 km from here
I will be in chicago I think!
les_w: stallman is kind a stalin, but without the massmurdering
If things go well....FACTORY!!!
les_w: factory is open
not closed :P
well bigger factory haha
not just turkey calls
K4ts: if you can came here for 27
I will go in catania to sse stallman conference
you came ?
gpl facism :)
BTW - the spirograph in the last picture was 38 inches in size
les_w: any experience about plasma cutter ?
I was wondering why 200ipm seemed to be cutting slow. ;)
my cousin is ready to buil a cnc machine
no, robin is the plasma expert
I know ..
I would like to have one...
Im waiting him ..
so, what abou the invention ?
Emc in factory use ??
well, it makes electricity from compressed air air
which is no big deal...
it has no moving parts and cost $2.
where do you get the electricity to compress the air ?
And yes I would like to use emc for factory use
and whats the use ? :)
um...no perpetual motion here haha
...hear some stuff like that here latley ;)
K4ts: .. are they talking about Leonardo ? :P
In general to run tronics....it only uses a tiny bit of air
da vinci ?
and you reload with a bottle full of compressed air.. like a firelighter with butane ?
les_w: today is the woman day!
hmm heh could I guess
when I was married every day was the woman day.
les_w: and its more efficient then lith/or pb akkus ?
in italy 8 march day women
I see k4ts
K4ts: it seem not so popoular there :/
well batteries have their use...
I'm jumping up and down excited about it but they won't let me say much
les_w: icic, wlel, have to waiut to buyit. 2 dollars seems worth alook :)
patents are applied in some countries where public disclosure invalidates the application
at leat K4ts was waiting a wish
we don't have a woman day
we have a mother's day
a nd for woman who dont have any son ?
les came on in italy
actually a woman day would be very popular here I suspect
mothersday is a christian churchthingy, we got that too here
i not understand
kats: just a addon to what les_w said
K4ts: its simple
they do not have any woman day
we are the first !
in the world :D
they have a motherday
mamma day ok ?
did you understand ?
in italy day mother is 9 maggio
kats: ok, took a fast look. the brits came up with it. back in 1300 wikipedia says.
because she's waiting for wishes..
to thank mother church :)
aspetto le mimopse
haha, everycountry has another date :)
lte me trsnslate 'mimose' ..
les_w you around?
cncuser: cradek and I were just trying out your new cd .. unfortunately, we had a joint following error, then axis misbehaved, and after ctrl-c'ing it a few times, emc wouldn't start again.
27. Mai Bolivia , 12. August Thailand , 10. Mai southamerica...
cncuser: cradek's rebooting and we'll see if it happens again.
jepler: could i help with anything ?
cncuser: this was with the "vertical mill" config .. oh and btw the descriptive text shown in pickconfig should probably be changed
K4ts: wee, mimosa mean mimosa :)
jepler: yes, i got a new one, i remaster it after i incoperate changes to the init
I have mimosa onthe land here
jepler: dont use those configs
anyway have to go out for a little while
I wish anna happy woman day!
les_w grab me when you get back
les_w: every year at this day we use to give a mimosa to every woman
les_w: mimposa for me
jepler: the cooltool configs. i dont know how much erroras are in there :)
cncuser: so you're not surprised I got a "joint following error" using them?
mimosa == OJ and Champagne?
jepler: no, for i havent had a chance to test this on a machine
K4ts have 10 on me =)
jepler: its tested today and tomorrow.
Jymmm: this evening a lot of womans are leaving anything to go out for funny
giacus have video camera ready?
they use to go in a group of female :)
jepler: theseare the old configs i modified in a rush a day ago at the end of my marathonsession
jymm i mo group bleachhhhhhhhhhhhh
Jymmm: oops got kernel panic if I coonect usb windows camera :(
no I dont have any
giacus: laptop ?
K4ts: yes, you're at home
but say how the things are going really .. :)
isnt tru what I sayd ?
ive had severall issues with older notebooks and usbdevices sucking them out so the system gets unstable and resets or hangs
cncuser: kidding ..
on my web site the trees to the left of the barn are mimosa
I use gnomemeeting with anna
[21:17:58] <les_w> http://www.lmwatts.com/
work fine ;P
didnt get it
I had on with the trunk one foot in diameter
les_w: Do you have any pointers on making a light tube?
well just insure total internal reflection
by choosing angles and refractive index
les_w: I want to edge-light a sheet of acrylic. I was thinking of using a .25" sq rod of acrylic as the light source.
with typical plastics in the 1.3-1.4 range critical angle is about 41 degrees
les_w: came here http://catania.linux.it/
les_w you totally lost me. Should I draw up what I'm talking about?
cncuser: click the "start emc" icon. select "vertical mill". Press F1 F3 F5 g0 x3 y5 ENTER. This sequence gave me a joint following error both times I tried it
tiger-rome -rome-naples- naples-catania :D
so, you can see taormina, naples, pompei, in few days :P
would love that
les_w: can you tell me accel/speed settings on your machine?
I want to make some plots
les_w: could be nice
les_w: Ok, gimme a few...
alex, I can only run at 3 ips and 30 ips^2 with the current (old) tp
what could you run with an ideal TP ?
a little more since the #ifdef
but the machine is capable of 10 ips and .5g ( 200 ips^2) on x
I mean what could the iron do?
about 3 g on y and z
that's 1200 ips^2 ?
I can actually do about 1g on x but I derate to protect the ballscrew
it's a quick machine
y has a peak thrust of 10,000n
alex_joni: hi, rtai testsuite runs okay, what should i try next
but y+z mass is only 150 kG
I derate to 3 again to protect ballscrew
mike: loading a few components
and looking at dmesg
motor inertia is the main limitation on y and z accel
10 ips is F600 .. right ?
motor inertia is about 500 kg equivalent so total mass is 650
that is some crazy speed ;)
but it would hurt the ballscrew
very little friction loss
alex_joni: i load siggen messages says created thread /proc/rtapi/status says running
tasks has 1 periodic
I have 5 TPI screws fitted because it is a compromise wood/ metal cutting machine
jepler: thank, i check
mike: ok, so what's still missing/not working?
If I cut only wood I would use 2.5 tpi and get 20 ips
halcmd show comp shows only halcmd not siggen, is this where i should be starting
mike: I think I've seen that before
try that a few times?
see if that changes somehow
there was a SHM bug in rtai at one point, and it behaved the same way
mike: how much memory do you have?
it does change each time i call show comp the number after the halcmd entry increments
les_w: this is the program I'm running / plotting http://solaris.cs.utt.ro/emcstuff/spiro1-f600.png
Hey! someone else using mcedit besides me =)
Jymmm: it's the best
alex_joni: is this still xacc != yacc?
alex_joni: I enjoy it alot
les_w: at F600
cradek: yes, Xacc=200, Yacc=1200
alex_joni: I notice you have much longer blends in X
* ValarQ mostly uses an unholy mix of emacs and vi
plot at http://solaris.cs.utt.ro/emcstuff/xvel,xacc200,yvel,yacc1200.png
that looks excellent
cradek: indeed it does
I am worried about Yacc, that seems limited to 1000, not 1200 though.. probably bad scaling
alex_joni: that's normal, it will hit 1200 only on exact reversals
ahh.. right ;)
mike: why I am asking about your memory, we've seen the exact bahaviour you are mentioning on systems with memory > 1G. we concluded it was RTAI's fault for accessing that memory directly, and the linux kernel can't do that. it needs to map it into it's address space first (which is 1G), so bad things happen
alex_joni: you know I fixed that in my kernel, right?
with the 1G limit I think
mike: you can try booting with mem=990MB as a kernel param, see if that makes a difference
okay i have 2GB right now. thanks
les_w: did you see alex's plot of a high velocity/acceleration setup?
I think we lost les
so I am not the only one with emc2 running on a >1gb machine ;) I don't feel so bad now
I'll be back in a few hours
alex - did you see this? http://www.electronicsam.com/images/KandT/Screenshot-3.png
done with lermans do-while.
I see you where doing spirographs also. ;)
would be cool to make a spirograph follow an arbitrary g-code path
skunkworks: does that produce lines?
fenn: jepler made a script to do it on a rectangle
yah i noticed
fenn: oh you meant "follow a line"?
fenn: that's easy..
just use the stuff skunkworks has, and make the initial position what you want
It would need some polishing - I just have it run through x amount of times. No the exact amount needed to make a complete spirograph. It overlaps a bit ;)
i went to a presentation by the CEO of redhat yesterday
my question was.. "given that there are other, non-profit organizations out there that perform the same functions as redhat, such as debian (performing the integration function) and OSI and EFF (branding-linux and legal battles)... how does redhat cooperate, er... what is redhat's position wrt these organizations?"
his answer: "well, i personally feel that if it weren't for redhat, there wouldn't be any open source movement today"
he cites having given "over $2 billion in IP back to the community"
so i say wtf are you talking about giving ip back to the community?
turns out they buy the license to code they need for their enterprise o/s and then GPL it
or something like that
he said "put into public domain"
that's not GPL then..
but how can they buy a license and then release the software under GPL or PD?
they need to buy the copyright for that
i think they buy the copyright
they must be buying the codebase w/copyright
and on what software did they do that?
a "clustered file server"
which i guess is rh global file system?
skunkworks: If you started with jymmm's equations, I think you may want to stop at 2 * pi * lcm(R+r, r) or something like that
[22:12:58] <Jymmm> http://mathworld.wolfram.com/Spirograph.html
oh man the CEO of redhat should know the difference between PD and GPL or other licenses.
yes - I was going over your conversation - I think I can figure it out.
i hope he was just trying to simplify for the business people
surely $2 _billion_ could have been better spent than on code
[22:16:10] <giacus> http://www.beppegrillo.it/english.php
take the blue pillol
wake up :D
giacus: the funny part, that he doesn't mention, is that terminator seeds were invented in response to fears the GM plants would spread in the wild and become an invasive species
unfortunately it doesn't work, as the GM genes can cross-pollinate and escape into the wild
you can dream or wake up..
business has is limit
jepler: what is lcm?
least common multible?
leaf creation method
good luck coding lcm in O-codes
Landesk Configuration Manager, Leaf Creation Method, Life-Cycle Management
La Cumbre airport
Least Common Multiple .. finally ;)
jepler: don't make me do it for spite ;)
is there an int in gcode?
skunkworks: you can read the documentation as well as me
skunkworks: I think there are bizarrely named floor() and ceil()
I will have to look
I mean, rs274ngc's names for them are bizarre
floor() and ceil() are the names I'm used to
rint and rup or something
ok, time to party
cu later aligater
they have round, fup and fix
alex_joni: hi, appending mem=990M appears to have fixed the issue, thanks.
Is there an actual name for this --> �
AFTER the arrow
that's a space.
[22:57:09] <bill2or3> http://en.wikipedia.org/wiki/3%98
err, its in wikipedia, if you search
hmm it doesnt display anything here
did you just type in ~ ?
there are a couple different encodings that are common, there is no irc standard
� <-- Slashed Zero
so for us to communicate in non-ascii, we would all need to agree.
I pasted the � into the search box
I think Jymmm is typing in latin-1, and some of us may be using UTF-8, a newer encoding
I wonder how well chinese would come out
i think i may be using iso-2022-JP
no chinese in latin-1 of course
right - wondering about unicode or some such
unicode aka UTF-8 would work fine if your font is good enough
I've been surprised by hebrew and arabic characters in some places
xchat doesn't even have latin-1
irc is typically 8-bit clean, so you can use whatever encoding you want.
fenn: latin-15? iso8859-1 or -15?
yeah it has -15
that's close enough to latin-1
jymmm try it again
[23:01:11] <Jymmm> http://www.google.com/search?q=+%C3%98
look in the search box
didn't the charcter come thru ?
in your browser that is
yeah i see it in the browser
mike: glad it does, it's a RTAI bug..
heh, and it searches for "OE"
SWPadnos lets not go there =)
I see the correct character, but I thought the search results were funny
Well, if you seperate the chars with a space, you get http://www.google.com/search?q=+%C3%20%98
oh there's two characters?
official site of the apple computer
fenn: Well, i guess some ppl type two chars to get a single one. like a umlaut
Jymmm: you advertising?
yeah - first MS, now Apple ...
alex_joni I'm just trying to get the name of a slashed zero �
if it even has one
SWPadnos: you are correct
it reads as 'a'
you can read all about it here: http://en.wikipedia.org/wiki/3%98
more like 'ah'
[23:08:36] <bill2or3> http://en.wikipedia.org/wiki/<percent>C3<percent>98
like mr. Stroustrup
replace <percent> with a %
danish and norwegian
it's also "standard symbol for diameter"
which is probablly the context you saw it in.
bill2or3: it most certainly is not. That's U+2300
As one Norwegian tour guide put it, "It's not an 'O' with a slash, it's an '.'!"
haha that prolly didnt work on your end
No, no, the old skool way or writing zero so it's distinuished from the letter Oh
bill2or3: Using LATIN SMALL or CAPITAL LETTER O WITH STROKE for that purpose is akin to using l when you mean 1.
Jymmm: that's just a font thing
fenn no , a paper and pencil thing
doesn't that mean "the null set" anyway?
see ya, Alex
fenn: no, that's U+2205
Ah, ok.. I guess I was right, just wanted confirmation --> Though not its native name, among English-speaking typographers the symbol may be called a "slashed o".
much thinner outline
bill20r3 thanks for the url
(00:49:25) -lu-: okj grz
(00:49:34) Jack: ;)
robin_sz: still there ?
are we well?
do you remeber latest discussion we had about plasma cutter ?
was it the one where i said "no, dont do that"?
we where atlking about plasma cutter
oh, this was the discussion where you cousin said he had a 3 amp one that cut through 2metre thick steel
I sayd palsama cutter my cosuin have ca cut 4 cm steel
and I said it would be 125 amp, 160V
this is plasma cutter we have: http://www.cemont.it/amministrazione/scheda_prodotto_en.php_idp=347&idcc=24&from=lista
we need to build a cnc machine for that
I need your help !
ok, thats 150A, 130V .. I was close
I have one of those ..
or I had
sold it to my neighbour
any plan around ?
you have a few problems with that machine for CNC
