jepler: the rate ideally is set by the speed at which you turn the knob
(limited by the max vel for the axis)
in AXIS, anyway, the speed of an incremental jog is set by the slider, so you can do an incremental jog at whatever speed you like. I'm tempted to think that either both should have a selectable speed, or neither.
the UI needs selectable speed because the user can't change the keyboard repeat rate (at least, not while EMC is running)
axis has some special goo that is supposed to nullify keyboard repeat for jog keys
(I've always been a little surprised that "this is an automatic key repeat" is not available in the X event structure; it seems like this would allow each application to decide if repeat is appropriate for each key, rather than having it be a serverwide setting through XChangeKeyboardControl / XAutoRepeatOn / XAutoRepeatOff...
that does seem like an oversight
I even have that kind of flag in AVR applications :)
the speed of a wheel jog is supposed to be determined by how fast you turn the wheel

but that's for another day..
hmmm... looks like a frog rubber stamp....
a new release of pcbgcode?
how about cutting it in graphite and using it to edm a cast iron frypan... then frog burgers for everyone!
nice pattern, like finger prints, and if you zoom, like nw territory Indian motifs
jepler: Do you need vector grpahics like that?
jepler: I have about 1.4M
LawrenceG: You know, that's actually not a bad idea... Sell the pans to places like Black Angus, Chilis, TGI Fridays, Tony Romas, etc.
LawrenceG: I bet you could hit the docsk in LB and buy the pans by the container - CHEAP!
LawrenceG: There's only one company in the US that actually still makes cast iron pans.
yea.... family crests on each steak
fry pans by chevy?
LawrenceG: they even pre-season the pans at the factory
I love my cast iron pans... the smallest one I got/stole from my Great Aunt decades ago, and the other huge one I got at the flea market cheap
nice pans... big old dutch ovens are great when camping....
That's okey though, she stole my tupperware pitchers, so it's all good =)
I've wanted to try a dutch oven, oven was a show on PBS about cooking in them, just never have.
my first experience was in boy scouts in texas.... peach cobbler to die for
after chasing armadillos all day, I was a bit leary about the stew
Yeah, this guy said 1 coal ~= 35F, so if you need 350F == 10 coals
those southern folk sure know how to eat!

ah, here it is http://kwsu.publictelevision.org/stations/kwsu/dutchoven/recipes.asp
even has some video clips on the right side
mesa 7137 outputs are mosfets, trying to decide if I can hook the drain to 24v and use the source to drive an optoisolator that turns on at 12v
I'd use a big resistor
opto is engineered by JMK's company, will turn on between 12-24v
I generally trust them
oh, as long as it's 24V safe, then it's not problem
I thought it was a 12V opto
I thought mosfet turned on due to gate/source voltage
the 7i37 outputs are isolated, so you can use them as high or low side drive
SWPadnos: Per your request... http://www3.telus.net/public/dt0116/items/hugeresi.jpg
that could be enough ;)
I have some 200 watt ones at work
I have some 220 watt ones in my garage :)
and a few 90's
I have a couple of monster braking resistors in the basement, don't know their power rating, but they have cooling fins
yeah - the high power ones I have use a rippled conductor wound around a ceramic core (about 1" diameter)
we have some of those that are adjustable like pots, they masked the ceramic coating on the outside, and there is a slider that shorts the resistive element
HOLY COW BATMAN!!! http://www.cliftonlaboratories.com/images/High%20Power%20Loads.jpg
iirc there is only one good use for those.. now i forget what it was
is that a rheostat?
eric_u: no 50 ohm
eric_u: no, it has a different name
The military surplus load also uses an oil-cooled resistor, but the difference in construction technique (and expense) is quite different. Heath went with a standard 1 gallon paint can, whilst the military surplus load is custom designed with many fins for improved case-to-air heat transfer. To give a sense of size, I've laid a 12" rule on top of the surplus load.
hm, wikipedia disagrees with me so i'm probably wrong
my boss wants a high power < 1 ohm rheostat
eric_u: bunch in parallel
eric_u: tell him it's a binary rheostat =)
I worked on a digital pneumatic valve once
r2r not bd
turns out you can't really do that.
i could swear i just typed bcd
that military surplus resistor is just huge
it looks like it has a handle that folds out of the top
[03:57:55] <JymmmEMC> http://www.cliftonlaboratories.com/loads.htm
i dont understand - what's the paint can do?
it's a resistive load
fenn: the cna is a 50ohm dummy load, oil filled
fenn: for tuning up radios off-air
so you don't smoke the output amp
fenn: 1500W PEP of pure HF goodness
they need a load
Well, not to burn up, but yo tune off the air (no antenna)
so you're neighbors pace maker doens't go wacko =)
right, but the antenna normally represents the load
2000W continous use on the cantenna - damn
so, essentially the can does "nothing"
it doesnt even dissipate the heat!
fenn: it's a 50 ohm load to the transmitter
that's funny, I have a wifi cantenna that actually is an antenna
fenn: yes, it does
fenn: that's what the oil is for... disapating heat
seems to me that oil is a very poor heat conductor
fenn: If you are not familiar with the Cantenna, it contains a 50 ohm Carborundum resistor, perhaps 3/4" diameter and 4 inches long, mounted in a cylindrical shield, suspended in the middle of the can. The can is filled with a heat conduction oil (either mineral oil or transformer oil, as the purchaser could acquire). In free space with air cooling, the resistor might be rated at 50 or 100 watts, but suspended in
they should have used lead instead
nice big pot of lead :)
The Cantenna becomes uncomfortably hot after a minute or two at most.
that means it isnt rated for 1500 watts, silly
No, the military surplus one is
one more try on the mesa 7i37 mosfet outputs: the gate is driven by an opto-isolator? Anyone know?
eric_u, I believe so. there's a transformer that generates an isolated voltage to turn the FET on
however, note that it has a relatively slow turn-on time (check the manual, I think it's in there)
it's just to enable my drives, don't think that has to be very fast
eric_u: you could try emailing mesa too, or see if they have a KB/forum online somewhere
Isn't there a stand alone program using hal where I can just click on buttons and watch for smoke?
just drop some steel wool on it.
there is a 5i20 test panel I think
that's not a good experiment
dallur (?) made it
I know the result, and I'd have to find the steel wool, which could take longer than driving to the store and buying it
you can also use halcmd for that
eric_u: under the kitchen sink.... SOS pads
we use the plastic kind
where do I find the 5i20 program?
I think it's referenced on the wiki
[04:12:49] <JymmmEMC> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Screenshots
I'm not sure if it's just a generic 5i20 panel or if it's got some specific purpose

taig + 30deg conical cutters, yay
what does 'mathless' refer to?
its a current src for LEDs
so itll put like 10-12mA thru an led, from 3V to over 20V input
[07:13:53] <renesis> http://darkertechnologies.com/notes/2007/09/06/very-low-cost-mathless-led-driver/
heh, cost of parts is $.07
where do you get smt resistors for $0.01?
ebay from china, resistor kits
or was that an estimate? best i've seen is like $0.02
i got few thousand for like $15
heh, ill prob link to digikey part numbers so if $.02 is cheapest in reasonable quantity ill change it to that
still under a dime
guess i'm just not a fan of resistor kits
i had major gaps in my .25w resistor bins
so i bought a .25w kit and an 0805 kit
now i just have to fill in gaps when i use ones up
it looks like you do multiple passes over each trace, from the screenshot
its the pcb-gcode.ulp for eagle
is it because you set your cutter width as smaller than it really is?
you can set diameter for compensation, initial isolation, step, and max isolation
naw my cutter is a 30deg conical, so it almost has no width
i gotta make a fixture so i can do double sided boards
i should try it with gcam
you can feed it rs274x now
it works out pretty neat if it likes your gerber output syntax
pcb-gcode sucks at drills and outline milling
it does g82 on every line without all the parameters
and i dunno it just doesnt wanna generate my boards outline mill
ill just pretend i wanted to code this by hand
well this was hard to find but i found it
[07:34:43] <fenn> http://unpy.net/cgi-bin/viewcvs.cgi/eagle/ulp/
there's also an optimizer somewhere that rearranges the order traces are milled
who did that one?
cradek and jepler
have to try that
i've never used it, so i dont know if its better or worse
but apparently it works
it's what jepler uses to mill pcb's
it's a script for eagle
jymmmemc: yeah im using same kinda script for eagle
is that the gcode.ulp posted at cadsoft?
renesis: No idea, might try MD5'ing it and see if it's the same
god damn no wonder i can never read jepler's code: http://emergent.unpy.net/files/01172617016/fb.py
fenn: you mean that he doesn't use generator-expressions?
function composition in python isn't as nice as it could be :/
that code would look so much better in a functional language
* fenn snickers to himself
Vq^: before i head off to bed, here's one you might like better http://emergent.unpy.net/files/01172617016/fb2.py
not long ago i was asking about the precision of cnc...
[09:02:23] <robboplus> http://youtube.com/watch?v=oga_4uoCvnA
...got my answer lol
fenn ew my eyes just suffererd excess brackets
fenn: and that one would look better with parallel list comprehensions :)
it's not that advanced but neither very readable when written in python
Guest871 is now known as skunkworks_
Vq^: just showed up
fenn: you understand that none of those fb examples were supposed to be particularly comprehensible, right?
renesis: that gcode.ulp is a completely new version, different from the one on cadsoft. Probably it should have been given a different name, but that's life..
yet another thing I did not know units defined: $ units majorsecond
Definition: musicalfifth^2 / octave = 1.125
jepler: have you looked at languages where coroutines (generators) and functional composition is the default? (like Miranda/Clean/Haskell)
cradek: from this: http://www.childstoryhour.com/images/coloring/frog.gif
to this: http://emergent.unpy.net/index.cgi-files/sandbox/frog.svg
Vq^: no, I haven
jepler: wow, that's very interesting
that is one hell of a pocket program
what was that done with?
BOSS: gif->svg with potrace, then postprocessing with inkscape to repeatedly Inset the path
jepler: nice, when the svg is zoomed it takes on another character http://imagebin.org/10319
cnc tattoo ?
nah, that's what stippler is for
huh, today (different computer, maybe not following the exact same steps), I can't get inkscape inset/outset to work like I did last night
I have a sinking suspicion that inkscape inset/outset are based on some kind of bitmap operation. When I set the inset amount to 2.000px and above, it works. When I set it to 1.5px, it doesn't seem to work..
jepler: in tomp's zoom I think I can see that it's not precise
cradek: that's clear to me too, now that I'm looking more closely
so much for thinking I had stumbled upon a proper mathematically-grounded implementation of outset/inset
so get back to work on the one you were implementing from a paper!
* jepler slaps the table for emphasis
I'm busy with hardware lately
oh, not THAT emc
at least he read the channel description
there are a lot of EMCs

thanks, I'll get a dremel and get right on that
I think Jon Elson had an article womewhere about scraping long lathe bed ways or something
I believe he used an angle grinder for the big stuff
I haven't been able to find the article recently though
I can definitely understand starting with a grinder of some kind
cradek:are you scraping some ways?
BOSS: no, my machine need some repair but my plan so far is to pay someone who knows what he's doing
cradek: 122v http://www.cnczone.com/forums/showthread.php?p=340099#post340099
i have some friends that own a machine rebuild company that are experts on ways,they do awesome work
skunkworks_: cool, looks like that's not the problem then
BOSS: I think mine will be harder than usual because most of the wear is on the dovetail, I don't want to start with a job like that
is it your bridgeport
the guys at MTF in tullahoma.tn can do anything you can think of to it,total rebuild if you wanted,and a decent price
I'm hoping to find someone who travels through here - I have a couple leads but nothing firm yet
(here = NE)
btw,they do travel all over,and have a truck to move machines also
jepler: judging by your code, you should be really interested in Haskell :)
skunkworks_: I scoped the tach output and it looked good, I also pulled the motor brushes and they are fine (but a big pain to get back in)
I might look into what it would take to swap two of the motors - that would tell me whether it's on the motor for sure
the Z is easy to get on/off, but the other two probably aren't
hung up brushes might act goofy
one simple possibility - is there a quill lock?
also, if the quill is even remotely close to the manual machines, it may be "counterweighted" with a clockspring - that may need tightening
though I think you said that drive faults even when you're not asking for a Z move, so it may not be mechanical
no lock, no clockspring
well, then it's not those ;)
it's very free - I took the belt off the motor and turned it by hand
ok. I'm all for the funky limit switches theory then
you must not treat it very well - are you violant with it?
I don't think the amp knows about the limit switches at all
I thought the person on cnczone mentioned limits as something that could fault the drive
yeah, I'm no expert but I don't think that's right
but it sounds like the amp fault light stays on until some sort of drive enable gets set - could that be dropping out because of the limit or something?
skunkworks_: the lights don't start on like that, on mine
oh - ok
if there's a limit switch on when you enable the amps, they enable, but the control tells you that you have to jog
(before it lets you home)
the machine he's talking about must be a little different
"be sure to jog the right way" is what the manual says :-/
thud - oops
it should disable the "wrong" way but it doesn't know which way it is (only one limit switch)
well it should know - because in one direction the home switch is on too
huh, I might do that in hal :-)
so - when is the conversion starting ;)
5 people are already 'watching' my auction. and about 10 emails mostly asking about how I got the videos to work in ebay ;)

and I think he does it every time...
skunkworks:what u got on ebay?
cradek: sounds like reseating all cards and chips is a common way to fix all thats goofy with the bridgeport ;)
I kind of suspect the motor... yuck
the old boss controls would also get goofy when the lube was low
a bp service man told me years ago,always check the lube level before troubleshooting
it's fine :-)
cradek: do you mean - other have blocked his email and you get that status from sf? or am I reading too far into that?
yes that's exactly what happens
woohoo! my new power supply just arrived
spam software that does that is SO irritating
maybe he should call himself an "olde pharte"
heh - cradek: you should reply with that :)
explaining the problem (complain a little about the bad spam filters)
nah, he's done nothing wrong, I'm not going to bug him about it
heh the clock trade and spam filters dont mix

I hope I got gene's answer right in only two tries...

hoboken is fine but I just work there
I want to install ubuntu+emc with the live cd, but each time it stops at the same point when ubuntu live cd starts
I tried burning the cd 3 times and on different computer but I always have the sameproblem
at what point does it stop?
and what is the computer and how much memory is in it?
when it try to mount the drive I think, I don't remeber exaclty
just after the ubuntu logo
when the progress bar appears
what kind of computer and how much memory?
Yves_SIT, try doing a text mode boot: press esc to get the grub menu, press e to edit the current line, move down to the line that says which kernel is being booted, press e again, move to the end of the line and change the word "splash" to "nosplash", then press b to boot
unless this is booting from CD, in which case the process is different, and I don't remember it :)

Yves_SIT: I bet you don't have enough RAM
last question this works only on 6.06 not the last ubuntu 7
Guest879 is now known as YvesSIT
it works on 7.x, but there aren't any official packages for it, and you have to compile the RT kernel and EMC yourself
so 6.06 is recommended :)
oh :( how much do you think I need ?
512 for install, 256 after installation
if you can get 384 that is probably enough
we've had mixed reports about 256
true - I always think of RAM in powers of 2 :)
:) ok I see
I'll try to find some :P
I have had video cards not work at all - do you know what video card is in the computer?
also - if it is an onboard video card using shared memory - it will probably not play well with the realtime kernel
I don't know exactly but it's not onboard, it's an AGP Intel graphic card I think.
If all else fails - put in a different video card to try.
