can I make a three phase motor from a single phase motor? http://www.cnczone.com/forums/showthread.php?t=23378
if you read that thread, some credible people chime in to say that the answer is "sometimes"
but usually not
I suppose you could cheap with the definition and drive it from a single phase
3 phase motors are so cheap though...
true, people are giving them away
skunkworksemc, I got the same part number as you did (the GOAL3+)
we must have bought them at around the same time.
and this case/power supply: http://www.newegg.com/Product/Product.aspx?Item=N82E16811147099
yes, we did
there are cases where the 1PH motor is really a 3PH motor with a cap to give you the shift for the 3rd leg
my case.. :)
skunkworks Hey! where can I get a case like that with built in soldering iton
the camera did a nice job of stopping the fans.
wow - really these motherboards are nice
the %50 ones?

look at the task bar
Guess it's not THAT good afterall! lol
sorry - closed the wrong window
bummer. no DWIM interface
Do What I Mean
* skunkworksemc just had too much stuff open and pictures of stuff open.. ;)
youtube the latency test?
I meant play a video or four basically

heh - that makes more sense
I had a fan on the router, but my wife thought it was too cold to be running a fan, so she turned it off and the router overheated
did you explain that the act of running the fan was actually heating up the area?
good point, I'll have to remember that one
there are a couple of unhappy bobcad users over at cnczone
just a couple?
must be a slow day :)
it's sad they can't just sell the software
people would probably be ok with it
yep. most people complain about the pushy salespeople
one of their fanbois has jumped ship
[02:53:58] <skunkworksemc> http://imagebin.ca/img/ltRCwxW4.png
skunkworksemc: I hate you now
for <$75, you could join him
my wife would kill me
actually, this computer is pretty close to that one
tell her the fan caused damage you need this to repair
you have an all sis chipset?
yeah, the 961 or something
so this is a different, nforce3
I should run the livecd on it once I set up the new computer

I am using a pci-e ati video card (as you can see from the picture earlier)
I didn't see nofink earlier
[02:59:52] <skunkworks> http://imagebin.ca/img/CcIOjt9.jpg
your graphics card is half the size of your mobo
hopefully ati starts coming out with decent linux drivers
I'd expect that nvidia would open up then too
the recent code and documentation drop should insure that soon
of course, ATI had nothing to lose
skunkworks, do you have newegg link on that m/b.... certainly one of the best latency tests I have seen
you can't get it any more
other than the GTX280, ATI is top of the heap performance-wise. they're definitely best price/performance at the moment
eric_u, they're available again
are we sure that's the same board?
[03:02:32] <SWPadnos> http://www.newegg.com/Product/Product.aspx?Item=N82E16813135227
I'm pretty sure it's the same board, though as jmkasunich noticed, it may no longer have a CPU fan
actually, since newegg takes paypal, I can buy it and my wife wouldn't notice :)
* skunkworksemc is running a 15us base period and everything seems snappy..
it woundn't to 10us.. ;)
[03:12:28] <skunkworksemc> http://imagebin.ca/img/JW3vGd.png
I think the cold temps have reduced download speeds to a crawl
if you're optimizing for the fastest base period, you could remove parport.0.read. move it to servo. nothing acts on that information any faster than the servo thread anyway.
well I suppose it needs to be in the base period if you have a jogwheel or something like that
but for steppers, limit/home switches, estop, nope
Georgia Tech needs to take up basket weaving
football is apparently not something they are interested in
I could read my 2540 line ecoders up to about 400 rpm.. ;)
or 1000 line ecoders up to 1000rpm/
assuming perfect everything... ;)
skunkworksemc: with a parport?
I think I might have to let emc run all night and see if it throws out a rt error.
put a $500 piece of aluminum in the machine to keep it interesting
that's pretty good for a parport
I am saying that would be best case.. I think I should be able to read into the 50khz range though...
you contemplating using emc for the control on your amp?
of cource. (but with pluto and then mesa.)
haven't gotten flash working on this comp yet
heh - well this is pwm out of the printer port..
[03:29:41] <skunkworks> http://www.youtube.com/watch?v=eUmFKOVepYY&feature=channel
eric_unterhausen: what are you running?
eric_unterhausen: that prevents you from getting flash to work
running new computer
it's installed now
the second link you provided is the new board, correct?
I may have converted my son to linux by showing him the desktop effects :)
what desktop effects?

hello, is there documentation on how to setup a python enviornment to do something like the Axis helpers?
those aren't AXIS helpers afaik
regardless, just want to be able to something along those lines
python is an interpreted language - you don't really need an "environment", you just need the python interpreter
like this? http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Simple_EMC_G-Code_Generators
yes g-code generators
how was the windows setup in Qt?
axis doesn't use qt
I'm not sure what those g-code generators use
all I want to do is setup an enviornment to be able to do something similar
do you have axis and those g-code generators working on your computer?
(they should be, if you have EMC installed)
ok, then everything is set up already
just copy one of the generators and start editing
I think those things should all be renamed after the "arc buddy", in particular, the "bezel buddy"
but I don't know whre to find the widget documentation
just google the various widget names
jmkasunich:wow - there are a lot more gcode generators on that page now.
yeah, put that together behind a big dialog box and call it a wizard
jmkasunich: that wasn't necessarily directed to you.. ;)
what I was going to say is that I love this motherboard.
haven't looked at those much
Heh, I like the licensing
Guest820 is starting to take on a personality
Who's John Thorton?
He learned python and went to town
are you serious?!
:) and has been updating the docs tons.
JymmmEMC: yes, he's been doing tons of work on the docs
Damn fine work

LawrenceG: AH, lol
The design is kinda cool... http://www.freelancelogodesigner.com/
nice to be off the "please sue me" list
LawrenceG: P.eng being python?
LawrenceG: So you downgraded to hobby engineer?
LawrenceG: are you a civil engineer?
maybe need to start a new society... unprofessional engineers... sounds kind of "dirty"
computer engineering, but was trained as a metallurgist
after 30 years, I guess I'm still an "engineer in training", cause I never took the PE exam
eric_u: 30 years? how old are you? I for some reason thought you where in your 20s
but I guess I seem younger because of my childlike sense of wonder, or childish sense of humor
eric_u: are you buying?
not right now, I am wondering what gives that mobo such low latency
What are those USB things that can hold files called?
thumb drives. keychain drives,
spam, spam, spam, spam
Ok, it was a loaded question.... I wanted to see what ppl are calling them as they go by so many names... thumbstick is another.
any others that you guys can think of?
This will be my new pcb mill. http://imagebin.ca/img/huFdB7t1.jpg
have you seen the mod where someone put a flash drive into a broken usb cable? I have a flash drive with a broken case I'm thinking about doint that with
what is it?
what was it?
eric_u: I think thinkgeek has that
it was a xyz table for despencing liquid.
but it needs some work - it is like .007 per step as setup. way to low
is it upside-down?
yes - sort of. that is how it was setup - bit could be setup anyway
the plate between the electronics and the axis is not installed
here is it running with the dispensing software.. http://www.youtube.com/watch?v=zKZYj51Exn0&feature=channel
I'm gathering that the y position is determined by the differential motion between those two fixed steppers?
no - it is cable run. The way it is setup (which is cool) is the cables are routed so they are totally independent of one another
x stepper runs x axis/cables and y stepper runs y axis and cables
I think I can get this thing to zip around pretty fast.
I have a couple of small plotters that were run by cables, it was neat
only problem is no z
newegg still has an athlon socket A motherboard, problem is it takes DDR
it needs a reduction - or replace the cables with screws. the thing is very solid as is though..
newegg raised the price
what was it, a cake decorating machine?
probably adhesive or something
we used it for applying a clear domed liquid to the top of decals
it was uv cured so it really sucked for durability. we now use a 2 part epoxy like liquid
others use it for potting and such.
the way it is setup now with cables - there would be virtually no backlash.
I would just need a 7 to 1 reduction or so ;)
what are the ribbon cables for?
this had it's own motion board in it.
jog buttons and such
put servos in there :)
are those nema 17?
I don't know my sizes.. the flange is about 2.25X2.25
what do I search for to figure out how to install emc as a simulator on my desktop?
skunkworksemc: I think that's nema 23
[18:54:58] <skunkworksemc> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#Building_emc2_simulator
I think you would need some pretty hefty servos to run direct..
you don't have much space
putting those cable drives back together is not a happy task though
I know.. :)
have you done it successfully?
yes - a long time ago - this machine got a decal stuck in one of the idler pullys. (I have no clue how it happend) and poped it off. everything came undone ;)
skunkworks Heh, take pic so you can remember how it goes back together and toss under the cover =)
you could use the steppers for their bearings and rig up another set of motors to drive them
still 7 to 1 is quite a reduction..
I have gearboxes in my junk collection
.... and keep backlash low..
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2009-01-01.txt
I don't know how bad those gearboxes they mount on servomotors are
OT: I'm making a list of all the various distros, their variations (32bit, 64bit, live, etc, versions, etc. Anyone have an idea on catagorizing them so most would know where to look to find what they're after?
I have one harmonic drive that fits on a nema 23
JymmmEMC: is that a trick question?
hmm - I should work on cleaning the basement.
wow - I really should start using firefox.. It has spell check when you are replying to messages on forums.. (I need that)
eric_u: Actually, no it's not.
eric_u: Consider: Ubuntu 32bit v8.04 desktop livecd as example
dgarr: thanks for the link
np, distrowatch.com may be helpful too
It's a lil difficult to have a hierarchy with so many options
compgeeks has a bicycle helmet cam, I need 2 for the accident investigation after I get run over
Considere using labels like google does, but no structure
use a tag cloud
yes, but call your keywords "tags" to keep everyone a little confused
but no struture there for general display
compgeeks has some intel socket 775 mobos for $13
$distro / $distroSub (UbuntuME|UbuntuCE) / 32|64bit / Desktop|Server|Alternate / LiveCD|Installer / CD|DVD / etc
eric_u: I like the idea of a tag cloud, but not sure how to dispaly in a struture for those just browing )so to speka)
I didn't really follow what you were after, so I can't help
I have to admit, those tag clouds just make MEGO
eric_u: If you KNOW what you are looking for, the tag cloud works great. But if you just wanted to browser to see whats available and try something out, how to display it in a nice structure.
Example: Linux/Ubuntu/32bit/Desktop/version 8.04 LTS (simple enough)
When you toss in all the variants, it gets a tad confusing
eric_u: Heh, I have one that'll REALLY confuse you =)
not too hard
eric_u: Pretend you have a dating website, now how do you list the orientation of the person?
horizontal or vertical
that they can choose from
eric_u: sexual orientation

I bought a set of 4 l297/8 boards from Phil in Mo, and the price of l297s has kept me from building them. I'd rather put the $60 towards something better
not that there is anything wrong with the boards, I'm just not a big fan of the chips
where can i find a list of known-good motherboards for emc. Starting to troubleshoot why my latency has gone from 14k to 128k+
after some upgrading
there's a list of test results on the wiki, but I doubt anyone will ever say that a particular motherboard is "known good"
topls64: what did you "upgrade"?
