les hey there
was just checking out paltalk
man i got all my woodworking tools in Delaware and need to get some stuff ready for a show
I need some low cost video conferenceing
glad i don't do too many shows anymore :)
don't most digital cameras do sound and video today?
pfred I am involved a bit in power tool design now
hmm there aren't enough power tools already?
or just they're not sexy enough to entice more buyers?
I'm gonna make some more I guess
101V cordless amaze your friends!
just don't use this product in the rain ...
anyway I am having some problems with sound caerd
stick with creative labs
they seem most compatible
I want a good video conference system
cause I don't want to get on planes
I had sound card problems spent god knows how much time on it finally I said the heck with this $32 later I was in business
at some time time has to have some value
I am getting a high pitched sqeal when I record or use things like paltalk
oh that's feedback
move the mic away from the speakers
no not feedback...
are you sure?
it is interference with cdrw I think
pull up a mixer app fiddle with it
I am sure
I can get wicked feedback when I am capturing the mic here
it is a software thing
I pretty much can't monitor at all
I am using a very expensive pro audio mic and mixer system here
it's the sound card
hmm is it onboard or a seperate card?
can try changing slots if it's a card
remember my first job out of school was an audio r&d engineer
yeah don't mean you remember much of it tho :)
on board cmedia
on an asus mb
whelp there goes trying to move it
can disable it and try another card again Irecommend creative labs
not the best but well they're very common
I think I need to do that
I googled the problem
so they must be working for someone
common with on board cmedia audio
really not many really use mics
yeah onboard sound probably leaves much to be desired
then agian I wouldn't get no top of the pops just came out yesterday every bell and whistle on it sound card
that may lead to problems too
I just want to eveluate paltalk audio and dvd quality video
les this is like the best place in the world to buy hardware http://www.newegg.com/
because I don't want to go to china
man new egg is on the money!
I know of them
maybe they're not always the cheapest on listed price but they're reasonable when all is said and done
peace of mind has to be worth something
people want me to fly places...it's expensive and not fun
heck can even be dangerious
run into a high building enroute
videoconferencing is better
it's been known to have happened!
oh I like flying...
I am a pilot
yeah as long as people without big beards are on the plane
hey you with the boxcutter sit down!
I haven't tried to fly since then all I hear is long security lines
not that the security personal are actually going to find anything
so if I can talk to customers on a near dvd quality audio/video link....
that seems a good thing
yeah and you could setup presentations in a controlled environment hopefully too
well I wanted to show you such and such but it's in Tazmania right now or last i heard ...
I just don't want to fly commercial
what do you mean you don't like the huge coffe stain on my shirt?
I have flown hundreds of thousands of miles
but it's getting nuts
well you should start being concerned with the law of averages catching up to you then!
I always have electronic gizmos with me
have a beard so get profiled
end up in the little room
sick of it
hey you with the funky electronics and the beard ...
sit in this room over here
least you're not east indian are you?
man you'd still be in that room!
also...I have a problem with security being nasty
I don't like it
and I get pissed
hey how'd you like to go through life with a below average intelligence?
and that makes it worse
and have to deal with people everyday going places when you're not
so anyway videoconference
I bet them people don't evne go anyplace when they're on vacation
and even if they did it'd be just like being at work!
oh no we're at an airport!
yeah it sounds reasonable to me
don't they make phones today that just do it?
I thought i saw a commercial on TV
well I just need to see and talk eye to eye
show and tell never goes out of style does it?
like we are typing now but 2 way dvd quality video
well you'll need a good camera for that
cheaper than plane tickets
good camera probably have a godo mic
good video capture card
I have good mics...I was an engineer for shure
good vid cap card have audio in too
yeah forget them
camera will have one
you need to make friends with one of them porno website producers
that do the streaming live video
they'd know exactly what you need!
I don't have a problem spending some money for this
of course not it's a business expense like you said probably cheaper than roud trip tickets
still it is always good to get what one wants
since I need to go to china otherwise
as opposed to figuring things out by the process of elimination
whelp that didn't work
hey if you're in Tianimin square wath out for tanks
well I will try to figure out my sound hardware problem
and get this set up
maybe you need to attack it from the software side?
then the software will tell yo uwhat hardware you need?
it's a cmedia sound thing on an asus mb
yeah but what software do you plan on using?
netmeeting or something?
very high quality
new things are well enjoy the bleeding edge
be the first lemming over the cliff so to speak
well I'm sure you know what you're getting yourself into
I just want to set up a streaming video dvd quality chat room
but nothing ventured nothing gained
to talk to customers
heck there may be more money in setting up videoconferncing systems than designing tools!
people will be like wow set this up for us
so I don't have toget on tin cans for 17 hr flights
yeah that's harsh one way?
you know, I have flown to europe for a one hour meeting
they'd better have lots of godo inflight movies for that trip!
heck it just rained here for 2 days
it was nasty here too
so I know the cabin fever a little but not a plane for better than a half a day
yeah i cna't imagine how it smells
I guess I am not a good traveller
17 hours couped up with a plane load of people
it's gotta get funky!
I'd be like open a window!
if they had beds it would be ok
or just knocked everyone out as they got on the plane
fill the cabin with nitrous
I have often thought of that
it sounds inhumane
knock me out and revive me when we get there
and the only way airlines make a profit is to keep shrinking seat size
yeah I'm just not that personable for that length of time
I'd get edgy
heck what am i talking about I couldn't go 4 hours
need meds to make it heh
hey who's that guy clinging to the ceiling?
that'd be me
I have flown on those things enough
flying makes me a little nervous so I usually get really loaded
and that's before i even get on the plane!
Oh flying doesn't bother me
being a pilot myself
hey on the way down that ain't gonna help you out one little bit
I only flown like from here to Florida
where are you?
I take off out of Newark
so it's like an hour and a half
heck it's halfway over before i realize we've even left the ground
I always get a seat over the wing so I can't see anything
I did the chicago to orlando flight a lot
kids and folks there
once coming into west palm beach man the guy must have been a nam vet that was flying
we came in through this thunderstorm that was not to be believed!
and he just powered right through it like he was landing in a hot LZ
I swear the plane got hit by lightning
he didn't care!
ATC tells them where they have to go
I have been in some nasty turbulence
he dropped onto that runway like we were taking on flak
bet it was better than my first landings in flight school
we touched down a little hard
but it beat the beating we were taking in the air!
you know what them florida thunderheads can be like
I have flown in stuff that pulls negative g
the wings were flapping on that plane like it was a bird I swear!
but them things are like tanks i guess it took it no sweat
was like a 727 or something
negative g=stuff sticks to the ceiling
nah we didn't have any of that
but as i can remember he banked pretty hard at one point
they can takr 4.4g positive
and well everyone was pretty pale
I have done 6
nah no gees
just batman and robin angles for a little while
I guess it's a good thing we idnd't hit any windshear
come to think of it now it was a little bumpy for a bit
I fly parabolic trajectories some
zero g for 10 or 20 seconds
I keep both feet on the ground as much as possible myself
heck I'm not even too wild about boating
I do to
flying is $$$$
it's just what I'm used ot is all
I never flown that much or boated that much so I'm a fish out of water with both of them
really I donno which one gets to me more
well I grew up on the water in florida and am an aerospace engineer....so I can do them some
I know this one guy Dave we call him Old Salty
because he's like Mr Boat
and well he can kinda freak me out
because he'll go off the coast of Block Island out like 22 miles in a 12 foot boat and think nothng of it
and I'm like hey Dave ah ...
I can get seasick
I haven't seen land now for a while
never on a plane though
it's worse below deck too
need to see the horizon
he's got a sailboat too
he's a nut
he bought that boat it'd been on fire i think
so it took him like 3 years to fix it all up
I got sick flying only once
but not motion sickness
just had like a cold?
I came down with a sudden flu
were i na weakened state
I have had passengers that got motion sick though
It's not fun
hey at least you had gravity
them poor astronauts
you read anything about the MIR?
man that place was disgusting!
well I know about zero g since we do it with the parabolic flights
it feels weird
I've been on rollercoasters
dirt floats up from the floor
bout as close as I've come to it I guess
that's what i say!
yeah I always knew i never wanted to be an astronaut
you know the "vomit comet" flights NASA does
* pfred1 likes gravity!
yeah the plane that dives
that is what I have done
well whatever it does
nah gravity is my friend
I count on it
we tried to eat m&ms floating around
then most folks puke
I remember I was in Florida once for a long time then i came back here and my friends took me out the nite i came back
so m&ms float around some more
and i just about got seasick on the roads here
it's so flat most places!
yeah fl is flat
where iam it ids not flat
yeah one nite my buddies there they took me on this drive like 40 minutes
then we went ove this little whoop in the road
they were all excited about it
I was like are you kidding?
I've seen roads with worse crowns than that man!
yeah i guess they were flatlanders
I live in a place called Summit so you can imagine
well I grew up in fl
it's basically all hills here
20 years in chicago..alsoflat
I mean we got roads here you can launch a car
but here 200 to 6600 ft
actually get the whole thing airborne
we have 9% grades here
there's places i know where there's scars in the road from frames scraping
yeah when yo usee frame scars you know it's bad
but that nite I got seasick driving around here
well getting driven around
the next day i was OK tho
but it was weird
if you are the driver you don't get sick
probably that's what i was just thinking
but still if people from other places come here to drive
it's got to be something else for most people
our roads heck most of them were laid out before the revolutionary war
I have gotten sick driving on the windey roads here
which is funny
rapid transit was the last thing on their minds
spins in an aircraft do not bother me
that's what i'm saying driving here can be like flying
up and down up and down around and up and down
bicycling is fun here
regular stuff makes you sick
cept for the people driving
there's one road here I swear I can hit over 60
it's such a steep and long hill
well on a regular 10 speed not the bike i have now
your wheels would gyro
reminds me...need new tires on the bike
they cheap for bike tires
I just bought some for my garden cart there
I needed cables for my bike
so I go to this bike store get one bare cable for like $4.50
then I'm in Walmart I get a whole kit sleeves cables everythign for $3.00
and it was a name brand
I will have to check that out
you cannot beat Walmart!
and they do stock bike parts
yeah i got the bike i have now at the town dumps
some oke chucked it out because the chain rusted on it
it's a Trek liek a $400 bike
I was like I'll take this!
well...better hit the sack eh?
have to do some work in the morning
yeah godo chatting good luck with vid conferencing
call the company
back on in the morning
they tell you what you need
that's what I'd do
sounds like a plan
* anonimasu stretches
getting ready to hit the bed =)
also trying to decide what size to mak ethis router
I'm thinkin 18" x 24" x 6"
what ya think?
hm it sounds "tiny" but you were limited in space right?
I could make it bigger, but this is the size I'm thinking about selling initially. I'll probably make my personal machine 24" x 36"
ah that's better
I find my mill table a bit small.. for some stuff..
specially when facemilling
well, what you think abotu 24" x 26" for selling?
but I think you will have a hard time selling it :)
once you start making chips it's addictive ;)
nah, just use it to make another
ah yeah then it's easeir
Yep, then get a few sold and design something in aluminum (maybe)
what are you going to cut with it?
ok, non ferrous stuff :)
I am very tempted to try building a router
with a vital card and some servos..
never heard of vital
I am amazed at www.datrondynamics.com
it's a card like stg for running servos
250mm/s in alu is cool ;)
check the video on their page..
I think that's slower but it's still damn fast
Will check it out tomorrow.. calling ti a night!
I've got a way to convert a BMP/PNG/GIf/JPG to gcode? I've got a drawing I want to mill out. it's a pattern for a coin.
a 2" coin...
alpha: doing nasty stuff? :D
anyways.. there's some image to gcode converters out there
I remember someone from here doing that (with a laser), can't seem to recall who it was thou
no. simple stuff
let me upload it to my gallery
[09:17:44] <alex_joni> http://www.imagetogcode.com/
alex_joni, thank... stupid ftp isn't working
there are a few out there
google it up
[09:20:58] <A-L-P-H-A> http://lloydleung.com/gallery/coin_design/#
there we go
wouldn't it be easier to do that in cad?
[09:21:50] <A-L-P-H-A> http://lloydleung.com/gallery/coin_design/Coin_Design.png
that's what I want to mill... with the circle being the actual coin dimension is 2".
alex_joni, it was drawn in cad. but with TTF fonts.
acad-> dxf -> ace
acad ttf -> dxf -> nothing
let me try
it doesn't work with ttf fonts.
convert them to curves first
how do I convert the ttf to vectors within acad?
I can explode it.
I can explode the word dealer, but not the other text.
* anonimasu yawns
* alex_joni agrees
gnu cnc utilities has a program like that
I think they were named like that
'ight... I'll check that out.
if you cant find them tell me and I'll look for the url
Was thinking about running some tests on a 60m^3 virtual machine.
the one that's doing 50m/min ?
yup - Want to get the accel up to 1G or higher.
I imagine riding that =))
I'd be scared of the chips.
or rather, not chips.. pices that comes flying
I gotta run
I'm almost going to give up on this endeaver.
do it manually now! argh
type the text on a straight line, draw an arc, divide that arc by # of characters... place and rotate
I fucking hate autocad.
it just lost 30 minutes of work.
I hate it too
I have R12 for DOS and think it's great - have they made it suck since then?
I've used r10, r11, r12, r14. 2000, 2002, 2004. Been using for years... just that it crashed for no appearant reason. and I didn't save for a little bit.
ctrl-s is my friend.
do you have autosave disabled?
or don't they have it anymore?
they have it... but when working with large files, it lags the system too much.
so after any major changes, I usually save.
but I was a little engrossed... and forgot
I guess on windows you can't autosave in the obvious, non-laggy way: fork() the program, then in the child save and exit.
and if you fork, fine... what happens if you're in the middle of an edit? or change? you'll have mangled files.
so don't do it then
you'd fork when you dropped back into the main event loop and the drawing was in a consistent state
you'll also have to do something clever if the user hits "save" in the parent while the child is running.
jepler_, I'm not developing autocad... autodesk is. :) Tell them. heh.
well... my code works.
just need to see if I have an smallish ballend mill.
horray! :) found a bunch of 1/16 endmills.
hmm... if I had some 1mm end mills.
SWPadnos_ is now known as SWPadnos
* alex_joni is back
* paul_c finishes a test run with loads of short Z moves.
how's the 50m3 machine?
This run was with a 300mm^3 machine
300mm on X, Y, & Z
I was thinking of starting with CL & NML
are there any issues I should be aware of before I start?
beat you to it...
can I help?
Some of the issues... CL uses Gtk Ver. 1.2
and it should work on 2.0 ?
* paul_c has it compiling with 2.0
I was wondering.. what messages did you use from (but especially to) emc
I was going to get the RT code to compile on a BDI-4 box next.... But,
CL doesn't compile on 2.6 .. right?
there is no reason why it won't compile on a 2.6 kernel - Once the makefile has been hacked.
The more I think about PLC functions....
I see a need for the PLC subsystem to be able to command motion on one or more axis.
even if it's another axis
but the emc-axeses too
I wonder: what if you'd have an axis controlled by emc, but not by the interp ?
that would work with hal, not so sure on emc1
The interp piles motion commands on to a stack
yeah.. but imagine it like this
the machine is XYZ (for example)
but it also has another axis (say T for toolchanger)
the PLC motion commands either need to be inserted at random points on to this stack, or a separate stack is required.
axis T would need commands from the PLC, not from the interp
To claim that HAL will solve this problem is flawed
didn't say that HAL would solve this problem
I said I imagine it "might" be doable with HAL (but you'll need to send commands directly to HAL)
that wouldn't be a very clean way
HAL = Hardware Abstraction Layer... HAL != Do anything glue
HAL is NOT a communication or control library.
I agree on that
but it's a hook from where motion can be commanded (I'm not saying that it would be ok to do it like that, only that it's possible)
* alex_joni will be right back (15 mins.)

woohoo - party!
very little at the moment
I should probably get to work :)
yeah - that's what I say
(or I would, if I were in England)
how do you say that in the US?
(or more forcefully ... )
42250mm/Sec would appear to be the limit...
42250mm/min would appear to be the limit...
allo alex eh all..
nice big linear motors would take 40000mm/min
paul_c: 42m/sec would be smthg
Smoking, I'd say
but 42m/min is pretty awesome too
try and STOP it
Carbon Fiber - easy to stop :)
Dmess: ESTOP should halt it instantly
It does - And it makes a nasty BANG !
I've got some big gantrys on my robots (doing up to 1-1,5m/sec in rapids)
youve never seen a 50 ft boring mill with a runaway axis your trying to troubleshoot..
they really stop at ESTOP
yes the STOP... hurt tech's too...puckerfactor goes up
SWPadnos_ is now known as SWPadnos
some of the early linear motors were normally open and @ power failure the just went dead...
lathes were dropping turrets int tailstockes for a month or two at DMG
on our robots the brakes are on when no power is applied
but those arent linear motors...
with a brake on the back??
on the front
on the back there's a resolver
ive seen back have brake then resolver or encoder
Hermle put the brake on the top of the leadscrew on one little universal cnc i worked on
paul_c: can you explain a bit about realtimeio.o?
I was looking at ways of passing data to/from the h/w driver
that didn't rely on the realtime interface.
* rayh brb phone
paul_c: may I file a bugreport?
on what ?
I was just wondering.. the makefile says: Do NOT file a bug report. :)
* paul_c points to the "*** Warning. Unresolved symbols" message from make
Ignore any \" *** Warning:\" messages and continue to the next stage.
You can't file a bug report until you have a bug fix...
ok.. so first I'll commit a bug
and if you have a bug fix, you have write access to CVS...
then a bug fix
then a bug report
paul_c: may I slap alex_joni?
just to keep myself busy
Once a bug fix has been committed
No need to file a bug report !
paul_c: to krank the bug-fixes statistics up
* paul_c passes SWPadnos a large wet kipper
* alex_joni needs a break
hmmm sounds like athe american juducial system... at work..
* alex_joni is rolling on the floor
no - too quick and fair
right.. going back to work
* alex_joni is translating some yucky text
paints & such
polyurethan waterbased primers
on the text, or in the text? :)
that's what the text is about :D
ah - much easier that way
don't most chemical names remain more or less the same?
yeah .. kinda
but the definition of a primer definately doesn't
and I only got about 90 pages to go :(
Dmess hates translatin... did some layerese at one pt
legal contracts... whereto ..ih therfore art worthwith... crap..
paul_c: I see that realtimeio.o is built in BDI, how does one go about doing testing of it?
cat /dev/emc :D
At the moment, the tests are hard coded in the source code.
didn't find that dev. Is it only built for emc2 not bdi
don't think so
It is "work in progress" and not fully functional.
but it's got nothing to do with emc2
for now at least
More "Proof of Concept" rather than anything really usable at the moment.
does /proc/emc work?
jee.. epoxyester :)
sounds like a mad easter bunny :D
Yep cat /proc/emc/status shows changes to heartbeat and estop
/proc/emc was added more as a quick'n'easy debugging aid.
paul_c: can I try the CL stuff you did?
are you planning on expandin /proc/emc/status, or dropping it (or something in between)?
plan on expanding /proc/emc to cover a load of other things.
ok. note that there's a 4k (single page) limit on the simple /proc interface
SWP: but surely you can register more?
like /proc/emc/status /proc/emc/estop /proc/emc/io etc.
yep - you can create larger buffers on your own
right - that too :)
4K is still quite a bit of data.
the only limitation is no floating point numbers
but in "human readable" terms, it can run out pretty quickly
there's a pretty small range of floats though, right?
(like +- 10000.000 or so)
It is not the range that is the problem...
no, but a small range can be easily converted in to a 32-bit fixed point int
which can then be printed using the kernel print routines
(or a slightly customized print routine)
'cept it is unwise to use any floating point math (including conversions) in kernel space.
The proc handler is outside the realtime code
right - the emc code would have to duplicate float values into separate "printable" vars
which would suck, but would work
No matter what debug level I set in an ini, the cat shows the same 0x0.
the debug level in the ini is not used in the RT code.
Ah. And this proc looks at the rt.
rayh: how do you like the splash I did for emc2?
I've not run emc2 in a while.
it's not in CVS yet

well.. I hate to stay so long at work
so I'll go home now
The page I'm after *really* sucks...it has included in it a selection menu for probably every country and city on Earth.
Home is the nice warm place where your brain lives, I say
home is where your heart lives...
Where that is, varies from person to person ;)
my address hasnt been my home for a long time..
Finish this saying: A man's home is his...
They used to say castle, but I think garage is more truthful.
next move i told the wife...i wanted a workshop.. with a house of somekind attatched..
I'd need a library attached to my workshop
Gasp! and Surprise!
Now where in the world do I come up with a 'digital signature'?
...and I don't even have a Wacom tablet!
Hm...I don't think that's it. They only have a short entry box, and gpg outputs a couple lines for a sign
AND it seems unlikely, considering where it is
or maybe I'm wrong.
asdfqwega: is this for sourceforge? You want to use ssh-keygen, then paste the contents of the "whatever.pub" public key file
No, this is for submitting a resume to a company

been waiting 4 wks for an MSI Mobo on warrenty.. the board is discontiued.. so i cant even find a replacement
* paul_c downloads a few more CNC programming manuals....
paul... i have some i can post FOR YOU
To England ?
cd's dont cost a mint to ship... or i can post to homepage.. i think... from this box..??
did you get the siemens link last week??
Yes thanks... Downloaded the whole site.
and also Boosch
the 840D is a beast of a box... i wish EMC2 took a look at some of their features..
the 5 -axis stuff gets SOOOO easy.. even programming AT the control..

hm, siemens and easy is something totaly different
Heidenhain controllers are much more user friendly
Imp... i agree.. but if your a programmer to start with Siemens gives you total control... Heidie... says sure ... do it MY way or the highway...

hey, on a computer, there's those little power cables... yellow, black, black, and red
as is my understanding, yellow is 12V blacks are ground, and red is 5V
now when i put the multimeter up to each contact, i get nothing... and the computer is on...
i have it set to V DC
'cause i wanna pull power for my buffer from the computer... such a nice convenient source of 5 V
i can't seem to get it on the multimeter
to register as such..
are the meter probes plugged into the correct sockets?
(often V and A are different connections)
hmm.. it's got 4 ports
one says 300ma
another says 10A
use the other one
and one says V :ohm: and an arrow into a line >
that's the one
that's what I have the thign pulgged into
there's also a COM port
are you measuring a cable that comes directly from the PS, or is it a fan connector (ie, is it plugged in)?
well it's an extra line coming from the power supply
not plugged into anything at the moment...
OK, but direct from the supply.
Can you measure the voltage of a battery or something to test the meter?
good thought.. lemmie find something
hmm... lemmie try the other probe cable...
you can also put the meter into ohms or continuity mode, and make sure you read 0
no, still nothing..
it might be the voltmeter
and if it's been a while since the meter was used, replace the battery in teh meter.
ok.. i get nothing from the computer, but if i touch the probe to the 300mA port, i read about 7.3 ohms
touch the two probes together, and you should get something around 1 ohm or so
on the 10A line, i get about 21
no - from COM to the V/ohm connection
to the com
OK - that's with the two probe leads plugged in?
(ie, connect the meter as though you were going to measure the computer voltages, but then switch the meter to ohms, and connect the two probes together)
it fluctuates between 1.4 and 1.5
now just switch it to VDC, and connect the ground lead to the case somewhere and the + lead to one of the two power lines
i just got it
it came up 5.1 ish volts
that's close enough
and the other one, 11.8
that's my five and twelve
pemmet: You're not doing electronics are you ?
gonna let the smoke out...
Dmess: is trying to compose a letter to get RIM to PAY to attend a Tradeshow he's orginizing... and it don't look so good batman
les : just read your post about frying gecko drives; you ever come up with a conclusion by chance?
* anonimasu is writing code to get coolant working
or even extDioWrite(CoolantBit, 1);
paul_c: plc > relay
Click (as I push the button) :)
(though I guess that's not really code)
Eh... spindel spinning == coolant_flow!
hm, that's not my issue.. I cant run flood coolant
but I have a homebuilt ejector pump that I'll run..
and just pulse the coolant in intervals..
so when I dont have the fluid on I get air..
cant run that... since I have not vent..
so it's a bad idea..
you need ventilation for mist coolant?
oh, my eyes speak for themselves
isn't that what guards/shields are for ? =)
I dont have that either..
I ran it a bit with less coolant so it caused mist instead..
the fog in the shop talked for itself
anonimasun plexiglass is cheap =)
Jymmm: yeah, but I do not have time to build a enclosure..
anonimasu trash bag is even cheaper =)
acutally cost is irrelevant..
trash bag + duct tape =)
time is worse :)
I wish I could run flood coolant that'd solve loads of problem
I was just watching the video here http://www.datrondynamics.com/
it seems the mist coolant only engages when the cutter is in contact with the stock, then stops when raised
what did you think of the speed?
anonimasu too slow
anonimasu: My $500 one will cut twice as fst!
Jymmm: well the vital card you will need kills your budget.
anonimasu I'm kidding!
I crave for that speed..
three times as fast!!!!
i dont care for ferrous materials..
at thoose feedrates milling alu is efficicent
anonimasu oh you want an aluminum frame on a car or roolcage?!
aluminium frame wouldnt be too bad..
not if you have a motorcycle engine ;)
Jymmm: the racing car I am working on at work has aluminium wheel hubs..
and kevlar * to keep the weight down..
wheel hubs?! eh, no thanks
it's a division1 racing car..
awd + 550hp
I think the guys designing/building it knows what they are doing
as long as I'm not driving it!
actually it'd be fun to test drive it..
they use black primer because it weighs less then other colors..
I'd still prefer a steel rollcage
heh the rollcage is chrome moly
same as they use in WRC
doesn't chromemolly have "brittle" properties to it? Somewhat slightly like cast iron?
well it's classed the same..
that cage is probably more expensive then my car..
Hey they can make the parts on my $500 cnc router!
How far have you gotten?
Alot still in my head. Going to start CADing it up today. I'm still asorta in a delima on size,
I'm sorta thinking 24" x 18" x 6"
I'm sorta thinking 36" x 18" x 6"
that sounds like a ok size
like I said, I'm undecided. could be 18x24 or 24x26
I want the 6" only incase someone wants to do boxes
engraving I mean
It's ALWAYS bugged me when I see Z's be so small
hm, you will need a VERY VERY rigid machine..
howdy Mr Les
Jymmm: the trouble with long Z travel is that the machine has to be extremely rigid or it'll flex..
anonimasu I'll give it viagra then =)
hmm got some pretty good quotes on spindles
except for ones with auto drawbars
you should go for one like that it'll save you in the long run
Just that feature cost about $5000 more
les what else you gonna do with your money?!
how much time do you have to spend changing tools to make it worthwile
les buy another pick em up truck?! =)
Ohmygod... Not content with tagging criminals, they want to get evryone before they're born... http://www.theregister.co.uk/2005/04/01/embryo_tagging/
well changing 20 or 30 a day sure gets old
count the time it takes to change a tool manually
about a minute if I hurry
two if I am not
so as much as an hour a day is changing tools
paul_c Sounds X-Files to me =)
well - a high-school kid only costs around $8/hour
Auto tool changer is a no brainer on that basis...but must consider cash flow too
so, you can have them changing tools for roughly 600 hours for the $5k spindle
think about yourself also...
if you go insane who will machine the calls?
there's a pretty nice little drawbar system that uses an air wrench as the actuator
anonimasu whos says he isn't already?
Jymmm: relative to how he is now..
Jymmm: obviously he is, otherwise why would he be making turkey calls? :)
you mean crazier...
anonimasu that swhat I'm talking about
Think about it... he's in the middle of nowhere on 12+ acres with nobody around... RedRum RedRum RedRum RedRum
the cat and chicken are around
I finally got EMC Live to stick to this system..
les: make something like this, and save yourself $4795: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5571249931
I think air powered drawbars at 24000 rpm are a different animal
must be a reason they cost so much more
even a Kurt retrofit will run you $1000 or so from MSC
the bearing for these thing are the better part of $1000
the drawbar loosener shouldn't be engaged when the spindle is running
so spring loaded closed?
probably air solenoid, but yes
I saw some vertex ones..
they were pretty nice but wouldnt go over 3400 rpm since they were following the spindle.. around
bellville washer type springs n real machines
yeah, but retrofitting a machine like that isnt easy if you dont have enough taper..
basic steps: engage solenoid, slow spin wrench (to set onto the hex drawbar head), rapid spin off, second pull with solenoid (to release tool)
best street price I have here for a 10 hp is $6080
without...(er collet) $2000
hmm the whole tool change thing sounds pretty easy then
used working 10hp perke manual....
I don't think it's rocket science, but I'm sure there are non-obvious details :)
Yeah I think I will search a little on it
tool dolly is easy to program...
sound like it
simple plc stuff
or just macro/variable programming
man - I've gotta study this PLC crap - I have I/O boards that could pretty easily be turned into little PLCs.
All I'd need (famous last words) would be a program to allow someone to program them
SWPadnos: you could write a ladder parser
If only I knew what it had to do :)
that's why I say aI should study a bit
I have a new board with 8 inputs and 16 outputs, a few LEDs and jumpers, and an AVR chip - sounds like it could be a nice little PLC.
(if I had put a serial port on that one - hmmm :) )
so, wie gehts?
* anonimasu yawns
hi les ..
some question about emc
some question about emc
i am coming from Germany. so my english is not so good
no problem some speak german here I think
but go ahead with your questions
on my Isel mill. i have a microstep steppercontoller on one ISA-board inside the pc cal�led MPK3. the software for this Card is very bad.
how difficult is the driver development with emc ?
can the steppercontroller accept logic level step and direction signals?
no, this is the problem.
what do they accept?
it's an internal ISA card - that's probably the problem...
the current for each coil of the motor (2 coils - bipolar ) has to be set with one 8-Bit Port per coil.
that should be an easy modification to emcmot.c
ah thank god you are here heh
bagi: so there is a pattern of bits you have to send to some IO port for each motor?
what is the better base - emc or emc2?
bagi: emc is the stable program, emc2 is the development work in progress
bagi: so that's a hard question to answer
bagi: are you a C programmer?
at the moment i have no schematik of the card . i had to rengineer if all 8 Bits are used for Microstepping.
I have written some c programms for embedded devices
do you know the pattern of bytes that is written to the IO port to make the motor turn?
yes i have some pattern for 1/16 Stepping
look at emc/src/emcmot/emcmot.c
around line 4540
you will want to make a function like lpg_phase_drive() that uses your larger table
then modify the calls to extDioByteWrite to write them to the right ports.
(if you want to use emc1)
if you want to use emc2 you will have to get help from one of the guys who do the HAL (hardware abstraction layer)
it is not easier to mod the tnb_fourphase_drive for more states?
they are almost the same
with both of these functions, there are multiple motors on one IO port
if your cards have a separate IO port for each motor, your code will be much simpler
thanks cradek, i will look tomorow deeper in the code and try to get some more infos of the card.
if you need help, come back here, or ask on the mailing list
the mailing list at sourceforge ?
but probably asking here is better
I am usually here 1500-2100 UTC
I'm leaving now, goodbye all
is paul_c watching?
after the frustration sunday, I've about decided I should just go spend a couple hundred bucks and buy something halfway modern to use as my main (BDI-4.xx/Debian) compuyter
Got a problem with the motion queue being emptied faster than it can be filled.
lots of short moves?
don't do that
need more buffer
I was hoping to pick paul's mind (and others as well) as far as computer recomendations
like AMD vs Intel, etc
and what works good with linux, specifically BDI-4.x
jmkasunich : memory, lots and lots of memory!
loadsa memory, fast CPU, avoid i8xx chipsets
jmkasunich 2 or 3 GB
NFW... I'm not gonna spend that much
1Gig of memory is way plenty
somuch for linux being minimalistic eh..
remember, I'm upgrading from 600MHz P3 w/384M, mostly using dumpster grade boxes
1gig is unless youre going todo design work on the same machien
if you guys are serious, then you've just talked me out of BDI4, Deb, and anything newer than 2001
that's fscking ridiculous
* paul_c is running BDI-4 on a 433MHz celeron with 256meg of memory
512MB is $40 after rebate
that's more like it paul
and that's PC3200 too
Sherline ship 2.4GHz boxes with 256Meg memory.
I was thinking 512M
EVERY machine I've ever owned has always maxed the memory limit and was better off for doing so too
and about 2.5-3GHz, or the AMD eqiuvalent
Jymmm - memory can be added later as well
but that is a good argument for 1x512M dimm instead of 2x256
leaves more open slots
start with a gig, then make it 2gig later on
I would say fix your budget and shop to it.
I intend to buy parts and build... mobo, ram, cpu, and video to start
hoping to use one of my existing industrial rackmount cases with the nice filtered fans and such
jmkasunich look at buying a cheapy complete system then just upgrading it
Take a look at a bare bones box - I found it as cheap & it came ready tested.
the really cheap ones ($399) use shared ram for video
already knew that mich
jmkasunich SO? just install a different video card later on
anyway, I kinda like the rackmount cases - barebones gives you a traditional tower usually
a barebones system for $180 isn't too shabby
$200 for a rack case..
just the case?
or a barebones in the case?
there is no such thing as a barebones rack mount
didn't think so
jmkasunich outpost.com search for 4199563
Jymmm: You are using the wrong suppliers
paul_c I have fry's ad in front of me
so if I use my existing rackmount case, I save $200, which can buy an inexpensive mobo and AMD Sempron 2500+ cpu
jmkasunich this ad is for a sempron XP2200+
128 DDR, 40gb, 52x 10/100 56K
skip the modem
Jymmm: I want more RAM, don't need drives (have several) don't need modem, don't need NIC (have several)
don't need cdrom or r/w (have several)
* Jymmm gives up
sorry, I'm more looking for recommendations about linux compatibility
the other day Paul said something about nvidia being among the most compatible video cards, for example
[22:28:43] <jmkasunich> http://www.microcenter.com/single_product_results.phtml?product_id=170146
$35 after rebate
* paul_c doesn't recall saying much about nvidia
oops... maybe it was somebody else then
to be honest, I thought I read a doc that said nvidia was _not_ so good about enabling open source drivers, but I think that doc was quite old
are there any URLs that evaluate stuff for Linux compatibility?
I don't have any problems using ATI cards, and most people seem to be happy with nvidia
thanks, that's the kind of info I'm looking for
in the past, I think you said you use Athlon instead of intel?
cradek's emc machine is an athlon. it runs great.
Most of my boxes are AMD, yes.
I'm using an athlon right now for that matter
from what I've seen, seems loke more bang for the buck than intel
from what I've seen, most go with AMD for overclocking in games.
my plan is to get mobo, cpu, ram, and video card, use CD-ROM and R/W drives, HDDs, and NIC that I already have
mobo and video card linux compatibility are the key question
A mobo/cpu alone is gonna cost you $200+ not to mention case/memory
I have the case already
unfortunately I know next to nothing about modern mobos
does your cse have a 350watt ps ?
What style of MoBo are you currently using ?
I can get this mobo http://www.microcenter.com/single_product_results.phtml?product_id=0181643
and a sempron 2400+ cpu for $99, but I don't know how good they are
depends on which box ;-)
I believe at least some of my boxes take ATX
* jmkasunich measures
the case I have in mind takes several sizes... what's in there now is 12" x 7.75" (ATX is supposed to be 12" x 9.6")
but there are mounting holes that appear to take full size ATX
take the case with you to the shop.
also need to check the power supply... the existing one is only 180W, hopefully the physical size is standarized and a replacement will fit
unless you have one of those mini PSUs
shame I can't put a modern mobo into the case I was working with on sunday
passive backplane ?
2U server, HP proprietary MB with riser for PCI slots, 2 slot SCSI hot-plug bays
I do have another system here with a pseudo-passive backplane
P2-550MHz on a daughterboard, something like 8 ISA slots on one side and 7 or 8 PCI on the other side
got lots of cards? ;-)
You can also get active backplanes..
You might be able to fit a standard PSU in the case, but I'd check that first
that ones 6U high though, too bulky
the one I'm looking to use is 4U
PS is about 6" x 5.5" x 3.5"
any reasonably modern mobo will have 10/100 (and possibly 1000) ethernet onboard
there are two main places I use for parts: Mwave and Newegg
so the half-dozen or so free 3-com NICs I have are just wasting storage space? ;-)
though they could offload a little network work from the CPU, if they're high end 3Coms
I was looking for the good ones
maybe 3C590 or something (can't remember though)
these former HP servers have a high end Intel NIC in them
you'll find that a new case costs less than a separate power supply
(case with PS)
afraid of that
but then, you get to pick the brand if you buy separates
it really comes down to how much I want the rackmount/horizontal form factor
put the tower on its side
the problem with picking brands is that I haven't been following the industry, I don't know what is good
it also varies by the week.
the cases I have are industrial quality, with filters, etc.. not just a tower on it's side ;-)
my problem (one of many) is that I'm a fscking cheapskate
that is a problem
jmkasunich DUH! =)
from where I sit I can see 9 boxes that I didn't pay anything at all for
jmkasunich I was trying to tell you an easy/cheap way of going about it
$378 for a barebones with MB, CPU, 1G, CDROM, floppy
it's hard for somebody like me to spend money on another computer
Kingston RAM, Abit MB, Antec case, Lite-On CDRW, etc.
gotta run - see ya
SWPadnos is now known as SWP_Away
Jymmm: I understand what you are saying...
jmkasunich I have a shit load of system here, and I PAID for them... so feel lucky you only have to buy one and have been able to get away with it this long =)
I even have a box full of 30pin simms!
all of it useless
I got rid of my 30 pin SIMMs... still have lots of 72 pins ones tho ;-)
use what you have to automated the lighting aroudn the house of soemthing =)
make them usefull for dedicated stuff.... maybe a mp3 jukebox or something
what I have ranges from P1-200 to P3-600... I _want_ something nice, but have a hard time justifying it in my cheapskate mind with all the rest sitting around
machine controller ;-)
jmkasunich: Here... instead of thinking of those as computers... mkae thme dedicated to doing things... they'll still serve a purpose.
maybe I should start putting some stuff _back_ in the dumpster at work
well it's comforting to know that some folks are frugal and get what they need without laying out a bunch of cash
I'm not one of those ...one of MY many faults
les I got rid of two PALLETS worht a few years ago
my parents grew up in the Depression... and they passed their traits on to me
les these were all personal stuff, not dumpster dived
same here jmk
use it up, wear it out, make do, or do without
but the traits did not pass
jmkasunich I'm understnad what your saying. That's why I suggested reusing them for other things instead.
jmkasunich do yo know how easy it is to make a jukebox out of those?
yes... one is the EMC compile farm (I hope to bring it back up before fest)
jmkasunich just get a 2ware card off ebay and load in 8 hdd's
my wife has an Ipod, I'm not much of a music listener myself...
I'd like to have one as a firewall/router
jmkasunich probably becaseu it's not convientant for you
12 hdd's --> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=39968&item=5181468842&rd=1
jmkasunich with that you can use all those old hdd's
just need a case and PS to run them all
actually, I have more SCSI disks than IDE, and I have a DAC960 RAID card
well, there ya go! I'm just trying to give you suggestions is all.
I have 6 or 7 fast (5.4mS IIRC) 18G SCSI drives
of course, one modern IDE drive gives more space, nearly the same speed, and far less power consumption and noise
the more I sit here and talk to you guys, the more I realise I bring home far too much junk
jmkasunich : I wish I had access to junk
it's a two edged sword gezr ;-)
See, I've over here right now playing with 3d CAD and my video card is just too old/slow for it that it keeps redrawing the screen whenever I try to do anything. Now, I COULD go buy the best damn video card I could find but this P3 800 is just too old to truely handle the new card. Such a vicious circle.
I tend to pretend I bid and won something on ebay, and then when i close the browser i pretend its 10 years in the future, and Im finally tossing out it
jmkasunich come on ya cheaper bastard... I'm the one over here trying to build a $500 CNC router... alright?!
want a free computer to run it?
jmkasunich does it includ *FREE* S&H ?!?!?!?!?!?!?! =)
I mean seriously, I dont have money to really buy gunk, but if I did, I would have a junk yard, and a business
depends, where are you?
that sounds westish
40 minutes south of Golden Gate Brdidge
San Jsoe Californai
no free S&H for you
see, I can be a cheap bastard too
which reminds me, I should be upstairs and outside enjoying the 65 degrees, instead of in here talking about computers
snow's almost all melted
on a serious note, maybe I should bring some of my choicer "junk" to fest and see if I can palm it off on people
I need a small worm and gear
that passive backplane system would be handy if somebody wanted to test cards... lots of slots
with exactly 40 50 60 72 90 or 100 teeth
gezr: you have a mill?
yeah yeah, the 50 and 100 arnt quiet degreific, but they are magicaly devidable
I've made worm gears before
jmkasunich : yeah, yeah, ive got the yeah, and yeah, and yeah
yeah I could make them :)
but have better things to do with your spare hours?
jmkasunich : my stuff is pretty limited, the big issue i have is gashing the hobb
using a dremell mounted in a milling atatchment on a lathe to position and grind the flutes is just embarassing
[23:22:30] <jmkasunich> http://www.metalworking.com/DropBox/_2001_retired_files/Worm06.jpg
gashing cutter and hob
[23:23:06] <jmkasunich> http://www.metalworking.com/DropBox/_2001_retired_files/Worm08.jpg
yeah, those look good
setup for gashing
[23:23:38] <jmkasunich> http://www.metalworking.com/DropBox/_2001_retired_files/Worm10.jpg
jmkasunich : I have to ask. Is that a deviding head below?
[23:24:04] <jmkasunich> http://www.metalworking.com/DropBox/_2001_retired_files/Worm07.jpg
overall view of gashing setup
I need the worm and gear for my dividing head :)
that can be a problem ;-)
dividing heads show up on ebay all the time, and are often reasonably priced
they are too big for my mill
you need a leetle tiny one, sherline sized?
you have the gear tilted at the helix of the worm?
yeah, that size, but a bit better
the dividing head is an ellis, bought it at a plant closing auction for $150 or so
im still looking at the tilting
yeah, its a beautiful dividing head
that pic doesn't show the tilting part so well
so the gear is cut at the tilt, and then it rests straight with the worm?
for the hobbing step, the gear is 90 deg to the hob
the gashing cutter has no helix to it, the hob does
thats a gashing photo then?
there's a whole series of photos and a text writeup
[23:27:38] <jmkasunich> http://www.metalworking.com/DropBox/_2001_retired_files/
down near the bottom of the page, worm.txt and worm01.jpg thru worm11.jpg
I tried a blank run of one, without gashing, freewheel mode, and I was unable to get the proper tool track, eventually I was able to form a sweet gear, but it was way below where I started
yeah, the gashing step is the key to having the hob drive the gear
I have an idea in my head that Im going to do some day, where I drive the gearblank
then you can skip the gashing step - that's the pro way to do it
have you made say a spur gear?
its basically the same process as a worm gear but the gear is advanced across the cutter I think, and it pretty much is a must to have the blank driven
that worm gear is part of a piece of lab equipment I built for a customer
I've done about 7 of them over the last 4 years or so
other than that I haven't done anything with gearmaking
its the only thing left in metalworking that just makes me act like a 10 year old
I can pick someones brains for hours reguarding gear making
I have some really good docs on it too
and photos and instructions for mechanisms
jmkasunich : do your table have a feed drive for it?
yes, X only
is is an electronic thing?
like a powerfeed, or is it tied in to the spindle in some way?
separate 1/4HP ac motor and 12 speed gearbox
(mill is circa 1941, no electronics ;-)
I did put a tiny VFD on the feed motor so I can dial in the feed I want
my little atlas, has a gearbox on the back that drives a shaft that turns the gear that moves the screw, I plan on using that drive rod to drive a single worm, that drives varous pitched gears to obtain the ratio
gotta deal with different center distances them
aren't spur gears easier (like lathe change gears)?
yeah, the worm's bearings will be on an adjustable slide so that it can contact the various diameters
yeah, spur gears would be ideal for sure, but I have to turn the corner
and then make the spur gears
to make the spur gears that im going to be making anyway
Im goign to be making a new set of spur gears for a southbend 9"
who knows, this is year #6 of that project
I was messin with the gear train on my boxford vsl...hobby stuff on the weekend
hahaha, oh well, someday, I have to go now, you guys take it easy
wanted to cut some 4tpi thereads
did you find a way?
yeah it's qiuck change of course...but subbinf a 40 tooth gear for 20 lets you do 4tpi
that is the lowest
have to go real slow
had no problems
but it was hobby stuff
I dont like manually threading a coarse pitch, without a decent thread lenght to work with
on the weekend I go in the shop and just think...ok this is not work I can just goof around
were you able to pull out at about the same location?
I just went real slow
does your boxford have the half nut lever on the left side or right?
It is basically the same as a south bend heavy 10 but with tapered roller bearings in the spindle
it is a nice small lathe
I bet its solid
We bought 5 from Chicago city colleges
fixed em up
sold the rest
going out for a while
jmkasunich is now known as jmk_away
I have to go as well
see you later gezr
Les : things going okay this week ?
