! TeX capacity exceeded, sorry [input stack size=1500].
If you really absolutely need more capacity,
you can ask a wizard to enlarge me.
that's the snide output from this latex2html converter
or maybe from TeX itself, I dunno
/usr/share/texmf/web2c/tex.pool:35you can ask a wizard to enlarge me.
does that mean there is some unintended recursion?
it sure seems to doubt I need that much stack

03cradek 07v2_0_branch * 10emc2/src/hal/utils/meter.c: partial fix for feature request 1020124 (halmeter scientific notation).
wonder if jmk will like that fix
cradek: the halmeter fix is fine
someday I want to make it nicer, but perfect has been the enemy of good enough for too long, thanks for doing that
I figured that was the problem, you're welcome
I know how it is
its been well over a year since I spent part of a morning talking to ray about that
I wanted to do something like real meters, with ranging to position the decimal point, autoranging, and manual range up/down buttons
plus a bargraph underneath the numeric display
I recently had to explain to someone that spindle-pos should go from 0.0000000e+00 to 9.9999999e-01
so you were motivated to fix it ;-)
I know you want real-world parallels (to meters)
to be honest, what you did is probably good enough that I will never do any more
but I don't see why you want to emulate the crazy decimal point placement stuff that makes meters hard to use
it reminds me of how you said maybe some menus would have been ok for halscope
for pure numerical display what you did is probably _better_ than what I had in mind
but the bargraph thing needs ranges
that's true I guess
but on the other hand, who needs bargraphs?
well I've never had a bargraph meter, but I sure do keep an analog one around
you can always scope it
* cradek shrugs
with real instruments, there is a big jump in (in)convenience between putting a DMM on it and hauling out the scope... not so big a jump here
I guess it's done :-)
feel free to close that FR if you like
I'm tempted to close out the feature request
I know I'll never do the bargraph
I won't either, unless somebody besides me really wants it
I'm gonna close it (I hate the really old ones)
welcome, no problem
eww, its worse than I thought
almost 2 years
that's 4 lines of code per year
I seem to have a block sometimes, I make things more complex than they need to be
I'm (in?)famous for telling a senior programmer at work "ok let's move on" when he was doing that
heh, you should talk to me more often then
how do you feel about a readout for unsigned like 16 (0x10) instead of the current 16 (10)
fine by me
to me that makes it self-documenting
I forgot it even had hex, there are very few unsigned signals in a typical EMC setup
I noticed that as I was looking for one to test it with
03cradek 07HEAD * 10emc2/src/hal/utils/meter.c: make hex values self-documenting
those were my only two complaints, both solved now, yay
the board with the leds on it is gonna add noise and hurt airflow tho
would have been better if they could have embedded it in the blade
wonder how they get power to the rotating circuit?
coil on the rotating part, stationary magnet?
I once started building a clock based on something like this
I drilled down the motor shaft, out the side past the bearing, then wired into a coil or two (brushed motor)
that wouldnt work with a fan
never finished it
no, must be a totally different scheme
hmm, he says that there is a bearing in the grille
so its not the usual inside out construction
I bet the center part of that grille (where the logo is) hides a couple permanent magnets
I'm a bit surprised at the low price tag
I'm not really
if it were programmable (include a usb cable and some crappy windows software) I bet it could sell for $49
most fans cost about $1 to make
that would drive the cost up a lot tho
I'm not talking about its worth, I'm saying I think people might pay more for it
usb chip, non-volatile storage, etc
at90s2313 can do usb and has a bit of non-vol for a $ or two
you can buy widgets that use the same technology to display arbitrary messages
I bet they're paying $0.50 for the chip they're using, maybe less
I remember being at a rock concert a couple years ago, some guy was selling these things that you could swing around your head
handle maybe a foot or two long, 2-3 foot swing arm
so you get a 5-6 foot diameter x 4" high scrolling message
wonder how it syncs
I don't think it did
that's one way to handle it...
actually, I wonder
I know the message wasn't locked in place
but if they didn't do _some_ sync, it would be all over the place on every swing
this was more like a scrolling message, so it was within a least a few inches on each rev
yeah, must do something then
or it operator skill
if its moving one way, spin faster, the other way, spin slower
the LEDs pointed out, but I'm sure they were vislble from the users POV
as it got dark (outdoor show) the message was _very_ visible from 50 feet away
sounds neat and annoying both
a good thing to sell
the target market definitely wasn't people who want to keep a low profile
actually, I'm not sure if the guy was selling the widgets themselves, or using the widget to advertise some other more normal wares
the more I think about it, the more I suspect the latter
heh, put a smaller one (maybe 12" diameter) on top of a hat
with a little motor to spin it
new take on propellor beanie
have you seen this guy's stuff? this is a really neat one.
a really neat something anyway
it's a flat painting
the entire scene in the jpg is a painting?
no maybe I'm on drugs, I have him confused with someone else
ok it's not so impressive then
or more impressive
it must have taken a while to build that thing

ok bedtime for me I think, goodnight
I hate ads, but thats cool

oops, maybe $5000
I meant "I bet that wasn't even that high" ;-)
* jmkasunich sleeps
greetings civilian :)
how goes it?
any new crap?
no, i'm afraid not
i have been thinking of rewriting some of the crap to use cairo instead
oho, question of the day
but there doesn't seem to be any accepted canvas library yet
Lerneaen_Hydra: shoot... not me I hope
is TP still "borked" IRT many G1's representing a curve or other shape
no, shouldn't be
but now (and a couple of weeks forward) i don't have time for coding crap :(
it was a few months ago
it was borked after the 2.0.0 release
I didn't know that
try running a file with lots of short g1
prefferably that follow a curve/elipse/similar
<1mm in length
I have a sample file if you want
Lerneaen_Hydra: that would be great
if you could mail them to me..
people are alive!
what are you all up to?
anyone want to see a nice form I create dynamically? http://126.96.36.199/invoice
dynamic pdf generation
only one graphic in there, the logo, everything else is vectors + text (two embedded fonts)
alex_joni: which mail?
alex.joni at robcon. ro
affraid of bots in here?
alex_joni: got mail?
you got mail.
alex_joni: there is some other stuff in the ngc but the interesting behavior is in the beginning
the rest behaves as it should
Lerneaen_Hydra: I think now.. was away a bit
could you test to see if you get erratic accel/decel?
only at home later
it should be quite prominent
what do you mean by erratic?
does it go outside allowed boundaries?
or does it slow down once in a while?
if the latter then I expect it to do that.. because of the missing lookahead
more like, hmm
I think I have a video
oh.. that's even better
I'll jsut compress it
xvid/mp3 in avi ok?
running a part of that file I sent
compare the behavior in the first 75% of the file with the last 25%
the first is short G1's, the second a g2/3
not quite connecting
as adress instead
not quite sure what you mean
I was able to watch it though
you can see that the step between a g1 and the next isn't very smooth
what time exactly?
did you scope the vels and accels using halscope?
try that first
I only looked at the raw output
and see if it exceeds the max_accel
that system is in peices now though
not very easy to test
I don't quite see what you mean
there is a bit of something around 00:29, but the signal is too much zoomed out to see
huh? that's just slow speed?
hmm, I don't know
not sure what else to see there
I was thinking of the sound during the majority of the move
do you hear the sound?
sounds pretty ok..
I see some jitter at the beginning, but that's normal
you can also see it, but to a lesser extent. when going from one speed to another (the difference not being very large) there is an intermedite speed far outside of the speeds between the two moves
that wasn't very understandable >.<
Lerneaen_Hydra: yes, that's how it works because of the pulse generating
you can only generate pulses at certain multiples of BASE_PERIOD
so sometimes it will be between two of those
it's not that that I mean
* alex_joni is lost
how do I illustrate this
you have flash player?
* Lerneaen_Hydra gets to work
check ftp again
now things may be more understandable
right.. sure seems more understandable
but I would like to see the velocity / accel graphs from emc2 first
do you understand what I felt was wrong?
first meaning before expressing myself about this :D
I can see
is it supposed to go like that? I can't imagine it should
mind if I grab it too?
by all means
take the AVI too
Lerneaen_Hydra: check the configs/sim/tripodsim.hal for ddt.* stuff
Lerneaen_Hydra: that sets up the speed & accel derivatives
looking at it now
the PID stuff?
shoot1 is... interesting ;)
it does look like jitter or something
that and pot can
in pot can the sticks are set up 1m from each other
and the file is 60fps
so you can get the speed of it :D
what's it used for?
fooling around with ;)
[10:46:55] <alex_joni> http://dsplabs.utt.ro/~juve/blog/index.cgi/photography/01155034250
you have to be very careful though

seeing that wouldn't be bad
something like that instead of a rock and an overcast sky

* Lerneaen_Hydra poke poke poke
oh btw, does anyone from borkland know of places to sell/buy CNC parts?
I have an unused compact 5 logic board (from my retrofit) that I have lying around
do you know if you can choose all counties instead of just one?
found another site
seems to collate from many site
similar to pricerunner
[11:20:47] <Lerneaen_Hydra> http://www.blocket.se/vi/8823952.htm?ca=11_s
<--- this is the type of mill I'm looking for
though cheaper ;)
that one was supposedly new though
what's a reasonable price for a working logic board for a CNC?
primitive but working
where's everyone gone? :(
what's a logic board for a CNC?
the hardware eqivalent of EMC+PC+parport+keyboard
are there any ilogic boards?
oh, you mean a controller ?
uh, yeah :s
very primitive though
only 90 degree radii, no decimal point (all units in 1/100 mm) and so on
tape data storage, though you can use a PC to program it
probably hobby grade today
odd hobba though :D
the sourceforge lists seem nice and responsive again...
hmm.. I might have a borken circular rail (ball bearing slewing rim - if that makes any sense)
borken? talk to Lerneaen_Hydra in that case
that seems the best thing to do, with me living in the land of borkborkbork
it's broken.. the only thing is it's 1000mm in diameter :)
supposed for more than 50kN force
part of a 5ton turn/tilt table.. not the easiest thing to unmount
5 ton turn tilt?
unless you need to take it apart
that's not that nice
Lerneaen_Hydra: pricerunner is vendor bought
anonimasu: yes, that I know
so do you really think a separate graphics card could solve my magma problems ?
I'm now at work, I could borrow an ATI radeon 7000 series card
worth a shot
but it shouldn't have anything to do with the sound thing
?? you mean I need a separate soundcard also or ?
I'd just disable it, and maybe prevent linux from loading it anyway
there does not seem to be a disable swithc in the BIOS
there must be (under embedded peripherals)
I can't check now but I tried looking real hard yesterday...
maybe I need to update the bios also
there were settings for the amount of graphics memory
btw. HEAD or AXIS is broken in a funny way...
well depending on your definition of fun...
well don't keep us in suspense
first, when I press play the axis logo gets milled but in the wrong plane, i.e. I have the white preview lines in the xy plane and the milling is in the yz plane
then, when switching between manual and mdi the axes display switches between showing x: y: z: vel: in MDI and 0: 0.000 1:0.000 2:0.000 in manual mode
sounds like you have the wrong kins
maybe I need a new AXIS from cvs ?
how old is your AXIS?
it's from yesterday
what kins are you running?
are you using nontrivial kinematics?
with sed, how do I run multiple commands at the same time?
sed "s/^192\.168[^\n]*//" "s/\n\n/\n/" access.log > access2.log
trying to clean up my apache.log
$ echo "foo bar" | sed -e 's/foo/FOO/; s/bar/BAR/'
I'm running AXIS/sim
etla: stock config ?
yeah, following the instructions I copied the sim and m5i20 dirs to ~/emc2/configs
do I need the common files also ?
etla: from where?
and why did you do that?
can't you run the config from emc2.head/configs ?
because I want to customize them and not have my changes undone whn I do a cvs update
use emc2.head/configs/etla-sim and etla-m5i20
that will assure no changes
selecting the sim config from emc2.head/configs does not help either. still funni things going on
I get your point but I don't think that is the problem right now
where can I check with what kinematics HEAD was compiled ?
it's not a matter of compiled
there's a hal command to load the module (loadrt trivkins)
and you should be able to see it with lsmod
trivkins is loaded, used by motmod
btw, I only did 'make' after my last cvs update, do I need to always do make clean and then make to be sure ?
no, but configure --enable-run-in-place wouldn't hurt
* alex_joni needs to run home..
etla: keep posting stuff in here, I'll read later
ok, I'm trying first cofigure and then make now
nope, first configure --enable-run-in-place and then make did not help
now I'll try first make clean and then make
ok, that seems to have helped ! now my axis-sim looks alright again
so, with the latest HEAD checkout it was important for me to do first make clean and then make
damn. now halmeter does not show any pins for me
I see everything with halcmd show
but nothing in the halmeter list
you're probably not running the right halmeter
you cannot mix versions
right. thanks. that worked
what is the logic in motion-spindle-speed-out ?
first it's 0.0, then I press spindle forward and it goes to 1.0
then I can do +/- to set it where I want it, say 4.0
I think 1rpm is the default speed
then I press stop and it goes to 0.0
but then when I again press forward I would have assumed it goes back to 4.0
it doesn't. it goes to 1.0
how about m3 m4 ?
yes, the m-words rember the last spindle speed setting. the buttons in AXIS do not
that's an emc issue, not an axis issue (and it might have been on purpose, I don't know)
does not seem very logical.
would you expect the halui on/off pins to work similarly to the AXIS buttons ?
yes I think so, since it's also like a gui
I always use mdi to turn the spindle on, I can't imagine clicking + 1000 times to get 1000rpm
anyone know how alex's new spindle speed override is supposed to work
similar to FO AFAIK
I set the .counts and I see it changing with halmeter
but spindle-speed-out does not change
although you have a max and min deviation from nominal as a percentage of nominal
there must be an enable pin somewhere...
does halui send the nml message?
yes I think so
the feed-override seems to work in halui!
it works for me too
L_H: did you try spindle speed override ?
the .counts and .scale pins look exactly the same but spindle speed does not work for me
not spindle speed yet
I don't need that tilll CSS comes
ok, so this is for alex who no doubt will be reading the logs later ;)
is it just me or does the apache license not require you to distribute source with binaries?
I start up axis-sim with HALUI=halui in the ini file
I have the default halui.spindle-override.scale of 0.1
and I link a signal rpm to the halui.spindle-override.counts
then I do halcmd sets rpm 10
but nothing happens, i.e. the halui.spindle-override.value never gets changed
the feed-override pins are very similar, and when I do the same it works fine, i.e. the feed-override.value changes, and AXIS also notices the FO change
hmmm maybe the maxSpindleOverride=minSpindleOverride = 1.0 ?
I wonder how I set the limits ?
ok, now I got it from halui.ini: MIN_SPINDLE_OVERRIDE = 0.6
and MAX_SPINDLE_OVERRIDE = 1.2
OK! now it works !
just need to put those two lines in the ini
since this applies to all GUIs that want to use spindle speed override, perhaps those two lines should be added to the default configs ?
gotta go, bye.
etla: for now only halui regards those limits
but tkemc and AXIS? probably will too..
trying to sort out last nights power failure, with outlasted my UPS's by about 10 hours.
are power outages common where you are?
I tried to do a gracefull shutdown, but the magma kernels won't.
common enough that I've invested in ups's all around.
There was power down toward the center of town, so without touring, I'd have to assume some drunk took out a pole, it never tried to recycle after it went off.
So I built a new kernel for this box, 2.6.18-rc4, feels ok so far...
also, when I get that box restored to life, I'd like to ask, from there, some questions re using rsync to make backups, anybody here doing that on dapper from outside?
how do I get SED to search across multiple lines?
I'm not sure, but in your earlier example the use of \n seemed to be to delete empty lines. In that case, '/^$/d' may be what you want instead -- match lines where the end comes right after the beginning, and delete them
I need to learn the modifiers.
but I have a pattern, that spans multiple lines, which I want to replace.
I'm only guessing here from looking at the manpage ("man sed") but 'N' will 'append the next line of input into the pattern space'
thanks, I'll try it.
look at 6.1.1.: http://www.sm.luth.se/~alapaa/file_fetch/unixcdbookshelf/sedawk/ch06_01.htm
bah... stinking countersink =(
Alright, if I have a machien screw with a head diam of .340", and I'm using a 90 deg Vbit to countersink it, what would be the depth I would need?
(I'm assuming the taper of the screw head is 90 deg, but it's actually a lil less that that)
* Jymmm nudges jepler trig abilities =)
I'd rather know HOW to calculate this
this one is easy
draw a picture of the bit and label the bottom angle as 90 degrees
now divide it in two with a vertical line, so that you have 2 45 degree triangles
write .340 on the "top" of the triangles
so that makes the top leg of each of the triangles be .340/2 = .170
now, the depth is the other (vertical) leg shared by the two triangles
it's .170 * tan 45 degrees
or maybe .170 / tan 45 degrees, I forget which
it must be /
tangent is the opposite leg divided by the adjacent leg
so .170 inches for a 90 degree Vbit, .294 inches for a 60 degree bit
I must be entering this wrong... http://www1.chapman.edu/~jipsen/mathml/asciimathcalculator.html
in most computer languages, tan() takes an argument in radians, not degrees
so you'd enter tan(45 * pi / 180) because pi / 180 is the conversion from degrees to radians
.170/tan(45 * pi /180)
If I knew what radinas were it just might help! lol
One of these days I learn trig.
radians are just a different system for measuring angles
for a unit circle (radius = 1 inch), an angle of 1 radian is an arc 1 inch long
so Actually, if I was to use a 60 deg cutter, it be: (.340/2)/tan((60/2) * pi /180)
there are reasons mathematicians prefer radians, but they're more or less irrelevant to a machinist who wants to work with angles
Ye old in/mm thing
(in a sense)
Does anyone know when Chris will be back?
Or does anyone know of a routine that can take a 1 bit scanned image, and make truetype out of it, by actually generating the new gliphs if required?
hard disk tracks are really thin!
<random statement of the day>
I have a hang sign I used to keep in the back window of my old Nissan 4wd, that I'd like to scan and covert into brass for my new Jimmy.
make truetype out of it?
Gene: there are programs for turning bitmaps into vectors, but I don't know whether any of them directly output g-code (I doubt it)
yes so I can feed it to truetype-tracer
I think cradek made a rasterimage-to-gcode program
do you recall what je called it
here are two I know of offhand: http://autotrace.sourceforge.net/ http://potrace.sourceforge.net/
image to gcode
it won't be vectory nice though
Software that uses potrace:
* FontForge, by George Williams. An outline font editor that lets you create and edit postscript and truetype fonts, among others. This program can invoke autotrace or potrace for converting bitmaps to vector fonts. It used to be called "PfaEdit". (Added Aug 21, 2003).
maybe you should look into potrace, but I have no personal experience with it so I won't be able to answer any questions.
nice! they actually seem to map the curves very nicely
got it bookmarked, thanks. But it outputs .ps. So now I need a .ps to gcode translator
is there such a beastie?
you can use TTT with the modified fonts
jepler: thank you.
Jymmm: you're welcome. I hope I got the math right...
jepler: it looks about right in the calipers
Ok, and autotrace looks pretty good to. Later, I thik the missus has her shoes on :)
jepler: One of these days (when I find the time - ye right), Maybe I'll put together a lil page with stuff like this.
I know how it is
but for me, it's the idea I should learn more about being a machinist
jepler: Same here, it's just that I don't know trig. I was thinking of jsut trying to measure/guestimate the depth by eye, but I remembered someone said trig is all about angles, and figured out that if I knew the width and the angle, that the depth should be able to be calculated. Even if I dodn't know how to calcualte it.
and you were right
Ironically, I could of asked in #math, but when you mention something of a practical nature in there they go huh?!
and gawd help me trying to google for the right terms w/o know what exactly I'm looking for trig wise.
Heh, I got a title for that page I writeup: "Trig for machinest that were fscking off in school.
lol "Note : due to the nature of the way in which all our software takes control of windows, it is strongly recommended that you do not surf the internet while using your machine for CNC work,"
alex_joni where did you read that?
heh, I ran IRC and FTP actively while machining :D
Firefox too I think
some doze software I'd like not to name :D
as my base_period isn't that tight there's cpu left for that too
bah. I don't see how you can trust that much moving iron to windows
'specially not a RT thing
Lerneaen_Hydra: people do some crazy things..
I've seen 100k$+ machines running doze
ftp://bdi4emc.ourproject.org/pub/bdi4emc/ <-- is it just me or has paul released the source?
and beeing stopped for days because of viral infestation.. if you can believe it
did doze control the RT stuff?
Lerneaen_Hydra: those are cd's with source packages
Lerneaen_Hydra: I think so
heh, at my school we have a real nice CNC lathe (10kW motor, from 2000 or so, driven tools, toolchanger, the works). Running an unpatched windows 98 *connected to network without a firewall and minimal antivirus*!
fortunately though doze only sends the program to a hardware PLC that does RT stuff
Lerneaen_Hydra: That page doesn't load for me. I do know he put an incomplete set of patches on another server, but as usual he has not supplied the debian/ directory contents.
one side effect of that being programs can only be 10 000 rows long.
which basically negates the use of the C axis, driven tools, and cam
jepler: it doesn't?
it has two ISO's (600mb+200mb) that are supposedly with sourse

Lerneaen_Hydra: I have not looked inside those iso files. However, I looked in the file http://bdi4emc.ourproject.org/debian/pool/extras/e/emc2/emc2_2.0.1.diff.gz
which does not include the changes in the debian/ directory that he must have made in order to build the binary packages
and here I was hoping that the source would be released. but noooo....
who's running BDI ?
with EMC stable as easy to install as it is today not many I guess
hmm.. paul released 4.50 recently, and says it has emc2 latest release on it..
but I can't see 2.0.3 anywhere
Lerneaen_Hydra So, you're not running BDI, but you wanted the source to BDI ?
Jymmm: I was just curious as to whether there was still a GPL violation
Lerneaen_Hydra: Until I've been able to build the .deb packages myself, I'll still believe there is a GPL violation.
In all honesty, who really cares? Is someone going to bring litigation or soemthing?
Jymmm: It's true that there's nothing "important" in Paul C's changes to emc, so in that sense it's no loss.
Jymmm: but to me it's a matter of principle. Paul should comply with the GPL.
* Lerneaen_Hydra nods
I can understnad that; but is it really worth all the anxiety, frustration, etc in the long run? I doubt Paul would do anything out of malice. iirc he's palying with emc1, you folks are on emc2 - completely different paths if I understnad the fundamentals correctly.
in short... pick your battles.
Jymmm: I think it's more about the principle
again, pick your battles.
in fact it was paul who mandated for GPL.. emc1 was and is PD
and the version on the BDI is NOT emc1
Jymmm: I don't know if it's malice, but I really do believe Paul makes a deliberate choice to hold back things that the GPL requires him to release.
Jymmm: if he's building the packages in the "normal debian way", a ".diff.gz" file would have been created AUTOMATICALLY that would satisfy the GPL requirements
Jymmm: instead, he created a file in a different format with some of the information removed.
Well, I don't claim I know the difference and history of all the flavors. YOu folks have parted ways, cut the ambilical cord is all I'm saying =)
jepler Yeah, I've seen the threaded over months on the packaging methods used. I can't comment on that.
alex_joni: I hate gpl. I'd love it to be PD or BSD personally.
Jymmm: that's your choice..
The merit of GPL vs BSD is irrelevant. emc2 happens to be GPL.
and tomorrow it could be BSD
it's just a license, and multiple licesne can exist.
or be revolked.
No, it can't be BSD tomorrow. Not without the permission of all contributors.
a BSD to GPL fork is possible though, right?
* Jymmm blames Lerneaen_Hydra for everything =)
jepler: Ah, didn't think of that =)
Jymmm: but if you want a BSD licensed CNC program, you can use the public-domain emc1 as a basis for it.
* alex_joni agrees..
LH did it
Jymmm: all you need is a cadre of really sharp programmers
/topic It's blame Lerneaen_Hydra day in #emc
jepler: don't tempt me :D
alex_joni: tomorrow it can be blame alex_joni day
my day isn't till next thursday

looks like that was a non-issue
* Lerneaen_Hydra makes a mental note not to prod/poke an OP, particularly alex_joni and Jymmm
and here I was planning to have some fun ;)
too slow :D
I'll have to make an alias that does /ban <names>
IRC sure has strange commands
/wii for instance
seems to give some info about pople
similar to whois
nice.. it has the idle time in there
14:54:39 No help for wii
14:55:16 /WHOIS nick1 nick1 also queries the idle time of the user. This is aliased to /WII by default.
doesn't do anything
just dissapears when pressing enter
Lerneaen_Hydra: Many "commands" are also client specific too
ltr == left to right, iirc.
try rtl and see what happens
hmm, yes I noticed, css in chatzilla shows which skin
oh, well chatzilla is something totaly different, ymmv
almost like sdrawkcab elgoog
jsut run /ltr again to get it back to normal
theres a lot more than just bans on freenode btw
/taunt would be nice
Lerneaen_Hydra Speak boy, speak. WOOF!
* Lerneaen_Hydra cries
Lerneaen_Hydra hows that for a taunt ?
that was supposed be pressed before I got unsilenced
the best would be if LILO wrote something insulting about the person in question
Yeah, well as alex_joni said... YOU TOO SLOW =)
and it got posted to all channels in freenode
it's not like I had much forewarning ;)
nah, walops are icky
kinda one of those necessary evils
what more interesting is there?
Lerneaen_Hydra Are you SURE you want to know?
what have I got to loose?
Per your request...
/ban doesn't need demonstration
that wasn't a ban. If it was, you would n't have been able to come back in here
it wasn't a kick either
does kick give a 5-minute temp-ban?
click on "how to use the network"
hmm, how do I apply.. er.. stuff like that
Lerneaen_Hydra has changed the topic to: test

jepler: the part turned out nicely =)
oh, that you countersunk?
Jymmm: You're the proud owner of some trig knowledge now
Tiny glitch, but I blame that on zeroing Z than anything else.
Oh I was at Sears the other day....
I saw a drill press they had with a laser pointer. It was mounted on the quill and instead of cross hairs, one beam was horizontal and the other beam was 45 degrees off from that.
The way it the laser point was mounted, got me to thinking that I might be able to buy just it and mount to me router.
I'm not sure how lasers are used to measure distance, but I was thinking maybe I could use that to create some type of toolsetter. What ya think?
if you get the angles right.. it might work :D)
I used to have a laser on my router
very useful for zeroing the thing on the workpiece
Well, when I moved the quill up/down, the laser module moved with it.
you mean the lasers shone in a crosshair-esque manner on the billet?
if they have a spinning/oscilating mirror then it can work
robin_sz do you recall how the tool setting took l=place?
it'l have to be lined up nicely though
mine was just a spot straight down
oh, simplest of all
ok, so maybe if I used a third laser, and where they intersect with be tool zero
set to U head, machine knows the offsets, put spot on cortner of wooden thing you are about to route
set x0 y0
set back to V head
U head ?
oh the softoware I used had the optins of 3 heads
U V and W
but you cold do it other ways in EMC no problem
or just put the alser say at X-100, Y100
on the router head plate right, 100mm offset in X and Y
then just set the laser pointing at the corner
and G91 X-100 Y100
or is it G92.1?
and how does that set the tool to zero top of material?
oh THAT part ...
I just used it to do X and Y o
I used to lower the tool to the top of the workpiece and set that as Z0
ideal way of working for signmaking
Right now, I use a flashlight on a steep angle and watch the shadow move to the tooltip. pretty darn accurate actually.
I had a microswitch on the bed, that measured tool length
Right, but lowering the tool to .005, .007 -.002 etc gets annoying
so I could swap tools without upsetting things
once the block height was set, I coud take the tool out and put a new one in, ask it to re-measure and then carry on
EONS ago, I used a microscope connected to a (no shit) TI adding machine. It would measure the thickness of whatever was being focused on.
hmmm ... handy?
you focused on the substrate, zero it out. refocus on the thickess part, hit a button on the adding machien, and it would calculate the thickness in microns.
it was being used on thickfilm microelectronics
is that stuff stil lpopular?
Sure, DOD =)
ive doen bits of it .. but nothing in years
prototype it on ultra thin PTFE board, transfer ti to TF and watch it not work anymore
these were ceramic substrates
yes, i know
we had some kit that had ultra thin PTFE based board, that was suppsed to work the same a a TF ceramic
the dielectric coeff of ptfe is about 2.2
of the ceramics it can be less than that, the idea was you played around on the ptfe and the etching tank, before they did the silly expensive ceramic thing
ooh, ebay purchase turned up :)
nice 415V 3 phase breaker for the spot welder :)
50A / phase and sloooooow blow
robin_sz: wanna check some pics?
not really :D

hey... alex_joni, do most europeans have air conditioning?
so it's a north american thing? Air Conditioning, that is.
most european dosent really need it
depends the hotter places have..
and well at offices usually
anonimasu, what temps does it get to? in °C.
A-L-P-H-A: wrong person to ask
about +30c at most for a few days
do you guys get humidity?
anonimasu should be happy if it's + there
A-L-P-H-A, heres the basics on the israel thing. sometime aorund 200 years ago, the arabs and the jews decide they didnt like each other. since then its got worse
then it's -40 in the winter
robin_sz, just 200 years ago?
well if you stuff jews in the middle of 5 arab countries knowing they dont like them what do you expect?
anonimasu, what country again?
I predict peace will break out one one side has got rid of the other
sweden's cold... it's further north than Toronto.
Toronto is mild.
we get +35°C sometimes... but like maybe a week, and then it's like high 20's + humidity.
the humidity is the killer... :(
depending on where you are in sweden it's mild too
is German cold? [no right?]
I don't get more than -10 during the winter
England isn't that cold... I hear just wet.
average summer temps of 25 or so, sometimes 30-ish
Lerneaen_Hydra, we in Toronto get down to -20°C, to 35°C max... but feels like -40°C to like +40°C with windchill and humidex.
but those are extreme days.
right now, outside is 13°C
and supposed to DROP to fuck'n 4°C tonight???
Google must be lying.
Where's my summer?
where the hell is google getting those numbers?

okay, then don't.
Should Tkemc display four places past the decimal in metric mode?
well, that's what it does...
in AXIS we chose to switch to 2 decimal places in mm mode
I imagine a patch to make tkemc do the same would be accepted
My application does not require a change , just wanted to make sure the display was correct
it is "correct" ;)
it's designed with inches in mind
I just got back to the project today
danex: good :)
what project is it?
_if_ you can tell..
The beveling machine, seven axis
nice.. add a frappr.com/emc2 pin when you have a chance ;)
I plan to add photos when the project is complete
So far my set up is EMC2 (ubuntu) two Motenc Lite Cards with their breakout boards
photos would be appreciated :)
I am having some problems with the PID, maybe with the drives
sure sounds like a nice setup
I have seen your replys to abram on the list
Small motors less than two hp
you caught me :D
soo 1-1.5 kW roughly?
Have you looked at the KOYO Hand Pendant?
1 KW and .5
[22:23:48] <Jymmm> http://www.koyoencoder.com/products/phd_estop/phd_estop.asp
only one problem with that.. small problem ;) RS422 interface
Jymmm: I found this: http://www.directencoders.com/shopsite_sc/store/html/ph_phd.html
alex_joni that one is fewer position and no e-stop
I misread the RS422.. it's not serial, but rather support for a line driver
hi all... ; )
danex: any link for the one you're talking about?
danex: anyways, one like these is trivial to hook to emc2 (given you have enough inputs)
the one jymmm put up
danex: both should be just as easy to interface
dmessier: ca va?
alex_joni: Your Google King-Fu skills are no good!
Jymmm: yes it is.. got me the 100$ cheaper version
and it's cheaper for a reason
From what I have seen, inputs do not seem to be a problem with EMC
this is nice too: http://news.thomasnet.com/images/large/490/490751.jpg
danex: if you're a parport only user, then they are
How many can there be in that condition?
ca va...comme ci comme ca jai arriver chez nous pour voir ce ci http://toronto.ctv.ca/servlet/an/local/CTVNews/20060804/glider_accident_060804/20060804?hub=TorontoHome
danex: if you still want to controll a mill with it, then you'll have 4 or 5 inputs
Can more paraports be added?
danex: sure.. probably +4 is realistic
I ran with 3 once
but you should have plenty IO on the 2 motencs
Crapeau.... ; (
Yes, I have many extra
* alex_joni heads to bed..
good night all
Good Night Alex
Good Night All
CRadek what is the prefered reading for learning the ins and outs of EMC? I am going through the manual that I down loaded from LinuxCNC.
machineitright: that's a good start
another interesting document is the one about emc2 internals
Thanks for the advice I can use all I can get.
[22:46:31] <alex_joni> http://www.linuxcnc.org/EMC2_Code_Notes.pdf
Is emc2 internals the code pdf?
and the one about HAL http://www.linuxcnc.org/Hal_Documentation.pdf
You type faster than me.
and it doesn't hurt to read the User Manual
machineitright: I spend way too much time in here typing :D
I have downloaded al of these plus the developers and intergraters handbooks.
those might be a bit outdated, but they might still hold some references
I believe anders found out from one of you where they were.
machineitright: also, the code is sometimes better documented than the docs :D
on Sourceforge, under Files, emc1 release 1.0.0
So you download the code to see the docs?
alex: This like comments in the code?
machineitright: right, you can also browse the CVS online here: http://cvs.linuxcnc.org/
machineitright: actually I meant this (http://prdownloads.sourceforge.net/emc/emc-docs-1.0.0.pdf.tgz?download
) when I said Sourceforge->files->emc1 release 1.0.0
but I think you have those (User, integrator & Developer handbooks from 2004)
I have worked with post processors and when making changes we comment on what we do and then use the ## so the post skips this, same thing I suppose?
yes, C files use // and /* ... */ for comments
bash scripts and HAL files use # for comments
The handbooks are from Feb. 2004.
not quite the newest :D
alex: What do I need to download in order to view the code?
machineitright: you can view it online here http://cvs.linuxcnc.org
or download the latest release here : http://prdownloads.sourceforge.net/emc/emc2.0.3.tar.gz?download
alex: sent the e-mail with the lsmod from my machine.
machineitright: yes, got it.. I think madwifi will cure it
machineitright: I gota run to bed now.. (2am over here)
thanks and have a good night!
machineitright: if you still have questions, bet there are others that can help
