come on Jymmm
if it is good music I'll listen to it
jt-plasma: Hey, we all know you're a polka kinda guy!
now polka your talking about the Big Jim Polka show
or what ever it was called
*I* wouldn't know
I'm a veteran cosmic rocker if you want to know
jt-plasma: I never hear the words "Pink floyd" come out of your mouth
I had a I (heart picture) Pink Floyd bumper sticker on my 81 Chevy Pickup
My now wife thought I was a cowboy till she saw that one day
so it came with the truck when you bought it, doens't mean jack!
BS, I put it there
Moody Blues and Pink Floyd are my heros
jt-plasma: Onlty because you couldn't find a "I [heart] Lawernce Welk" sticker - and for good reason too!
throw in some Kate Bush and Leon Redbone and we have a party
or Jim Stafford
BACK THE SHIT UP.....
You can't Put Kate Bush and Pink Floys in the same conversation
oh and don't forget Dr. Demento
Learn to speak typo!
jt-plasma: Floyd can't get anywhere near as high as Kate Bush voice
and don't let Kraftwerk escape your listening pleasure
I agree Mr. Pink doesn
t have the range of Kate
jt-plasma: Oh gawd.... Kraftwerk, haven't heard that name in decades
but don't leave Mr. Loaf
jt-plasma: You do? Who kicked you in the nuts over and over again?
Now it is the Shangri-Las playing
Leader of the Pack
jt-plasma: Don't make me open a can of whop ass and slap some Glenn Miller on the table
ok Dr. Hook
I like the coors, taylor swift, avril, gwen stefani,
Cover of the Rolling Stone
oh yeah and little birdy, rouge traders
Valen: I've not had the pleasure of listening to them
jt-plasma, a fringe benifit is they are all hawt chicks
I'm still searching for "From the Indies to the Andes in my Undies" but can't find it
oh boy some Jelly Roll Morton is playing now
nice the Pickup Truck Song by Jerry Jeff Walker
[00:16:09] <jt-plasma> http://www.youtube.com/watch?v=RWK8GgWD4uA
* jt-plasma wonders why you tube won't play over the speakers on 8.04
From Kraftwerk to Country.... You had (have?) a mullet at one time, didn't you john?
no, but I use to cast net them
liar, you had one!
home made cast nets
I had an afro once
or a perm what ever you call it
eh, that's ok.
it was worth it :)
did you marry her?
You actually have Krafwerk on cd/mp3?!
They have usb turntables and cassette desk now (just fyi)
my turntable still works :)
I meant to convert to mp3 - you sick puppy!
along with my Polk audio Model 10 speakers
Heh, I saw a pair of Bose 901's at the goodwill the other day
Damm, that is sad for sure
Yeah, I have no amp's or it might have been worth checking them out.
oh now it is Lynyrd Skynyrd playing Tuesdays Gone
or Bob Dylan playing the Hurricane
* jt-plasma goes in to check out dinner
jt-plasma: Hasta! =)
hmmm my isp is rolling out native ipv6
only problem is the unmetered content I ususally use would no longer be unmetered
which is somewhat sucky
Valen what do they meter?
I rip MP3s off my turntable
but they host ubuntu repos etc that are unmetered
Valen what is it wireless like on a phone?
no its adsl
Valen isn't dsl like bandwidth limited anyways?
I remember mine was
you get a quantity of gb included and if you go over that you get rate limited to dialup or so
Valen yeah but its pretty high right?
I mean lets be reasonable
10gb on my plan
but mine is an expensive service
its $80 a month incl phone line rental
for $50 you can get 50Gb ex phone on a residential plan
yeah 10 gb is a lot
download 2 dvd iso's of linux and you have used it all
one thing debian had was the nice network install
download 2 floppy images then net install the rest
heck I'd irc while it was doing it
lots of image crap you never use
not so good if your installing lots of times
Valen I suppose not but this system as an example I installed in oh 2003
SuSE Linux 8.2 (i586)
-rw-r--r-- 1 root root 36 Mar 27 2003 SuSE-release
maybe I should upgrade one of these days ...
jt-plasma, - John, you need to sudo apt-get install libflashsupport to get flash sound back.. a recent update broke the flash plugin for mozilla
LawrenceG: thats good to know
Jymmm, yea... I finally went googling and fixed my box thismorning
LawrenceG: I think I'm going to me one of these... http://www.arrowantennas.com/j-pole.html
I think there were some bad flaws in the flash plugin.....
there alwasy is.
those are nice solid antennas.... you can build one if you have some spare Al. I think I have dimensions around here... let me look
LawrenceG: Not for the price he's selling them for.
[03:28:50] <LawrenceG> http://imagebin.ca/view/IoxenR.html
can anyone tell me what CAD software people are using in conjunction with EMC2? I use Rhino3D and I am interested in the Sherline range of CNC milling machines, with the the 4th Axis. I am planning to machine wax for "Lost wax casting" of jewelry.
funkydruid: Are you looking for something cheap or ???
i started using heekscad/cnc, great software tho a bit unstable :/
funkydruid: It's probably not without it's own issues, so be sure to fully test drive it before buying, but it's CAD AND CAM all in one... http://www.artcamjewelsmith.com/
ahh 4 axis i dunno if it can do :)
yeah - im looking for something cheap
artCAM looks like a pretty nice tool kit
funkydruid, look it up on google
currently I use kerkythea to render my drawings. and I have access to a Roland MDX 20 mill, but I'd like my own within a budget :)
funkydruid: Heh, ArtCAM is about $10,000 USD
you can also check out Alibre CAD/CAM
they have some freeish version, full parametric CAD + 3 axis CAM is < 2k$
not even 4 axis?
for the cam I mean
they have up to 5 axis CAM
[08:02:04] <alex_joni> http://www.alibre.com/store/c-10-alibre-cam-software.aspx
th axis = $2K usd
alex_joni: how is it compared to SW?
I like it better
and it's way cheaper
can you call out dimensions like 12+3.5 ?
haven't used SW a lot though.. but when I did, I found some things easier/faster in alibre
Jymmm: model in alibre
alex_joni: you use alibre?
alex_joni: how do you like it?
ds3: enough to buy it :P
until a comparable OSS comes along

I'm tempted to put my Z in the pillars
it seems a good compromise of stiffness when low, and highness when high
"highness when high" :)
is there anyone here I can ask a stepper motor driver speed question?
I'm wondering what is a good target clock speed I should be able to run my motors at
depends on motor and steps per rev and max speed of your particular motors
and if using micro steps
and mass being moved
so far the faster I run my motors the less torque they deliver
yes what I want to know is what is a fair happy balance speed
like I can run my motor with a 35.5 uS clock
but at that speed you breathe on it and it'll stall
each setup needs testing, and base your maximum to allow for load variations
but if I run it at say .6 ms clock it is very powerful
you need spare torque for cutting load etc
well I don't think the motor will put out any more torque than at the .6 ms clock
around there is where I get very reliable reversing starting etc
if that's fast enough, try setting it at that then and see if it'll work for you
celeron55 yeah before I build three motor drivers i guess I was hoping for some reassurance?
celeron55 I'd hate to be out all the time and money you know?
clock speed is adjustable, we in here will be assuming you are using EMC to get that
archivist nope right now just a 555 timer
archivist adjustable with a potentimeter
are you ramping up?
in the final build?
* pfred1 is confused
explain ramping up
steppers need to accelerate to max speed
archivist yes I've noticed
if you're going to use emc, you don't need to worry about reversing and starting, because it will accelerate them smoothly
you can't start out at 2,000 RPM
this is all controlled by software
celeron55 hmm so I've been beating my head with these motor drivers for nothing?
2-3k rpm is about max for a stepper
the output stage you still need
archivist yeah it sounds like it is about to fly apart there
what driver chip are you using
SLA7026 with half stepping logic sequencer
clock and dir can be driven from emc
archivist I'm trying to put something together that emc can drive
remove the 555 and you have it
just was wondering if I was there yet or not
seems you are
well I've built a few different motor drivers
each one a bit better than the last
seems there are a lot of differentdesigns
* pfred1 is having commitment issues ...
probably all of them are good enough
for basic use
bipolar is generally better than unipolar
yeah these are just unipolar
should be ok
stuff is strong though I should duck tape it to my mill and see if it'll drive it
initially I didn't think the motors i have coulddo it but I'm not so sure anymore
you can then use stepconf to test at various speeds
they only 124 oz/in but
I'm wondering if people using much stronger motors just have crappy drivers
or crappy power supplies
124oz/in isn't that bad
celeron55 I'm finding that out
they can be
if you screw something up with the build
people generally recommend about 1Nm and 124oz/in is 0.86Nm
but this last motor driver i made is like a freight train
[21:35:32] <skunkworks_> http://www.youtube.com/watch?v=fl3om2mG5gA
* pfred1 has no Flash :(
why not install it
celeron55 they don't support my version of glibc
celeron55 or i could say I did but it doesn't do anything
so what OS are you using? :P
which is kind of nice for all the ads
celeron55 old version of linux
why not get a more recent one
celeron55 7 years of data
thats a lotta work
someday I'll just get a whole new machine
that is an awesome video
you can always make a backup and save the data otherwise?... well, on the other hand, "if it works, don't fix it" :P
celeron55 yeah if somehow I could backup 500 gb
tough to fit that on a floppy
yeah so emc will ramp the motor for me?
thats great! I'll make hard copies of these boards pronto and move on with all of this
I guess down the road i can always get new motors and make new drivers for them
I got one motor an old astrosyn thats a goliath
something like 4 amps a phase
haven't made a driver for it yet
you don't actually need flash for watching youtube videos if you use for example http://bitbucket.org/rg3/youtube-dl/wiki/Home
celeron55 yeah? because i have like mplayer
skunkworks, that blender addon looks good
but i'm off to bed now ->
archivist I think they named that software for how my head feels when I try to use it!
once i got it to render a sphere
that was about it :(
and the scene was so dark you had to know it was there
archivist_emc: doesn't it? I am impressed.
trying to find out more is hard though!
wth... it generates the gCode on the fly?
looks the sexy
I think it is someone on here... I thought I remember someone mentioning it.
can you make any of that stuff with those tools dimensionally accurate?
I don't know blender - so I could not tell you.
Hmmm, seems to be only outlining the wireframe and not the 3D it represents.
skunkworks_ you ain't the only one!
hmm no mention on the mailing lists
whoot this stuff works!
It's tracing. Not really doing 3D
skunkworks, ah you found it
skunkworks, google fails to find some emc wiki pages
archivist: Ok, so am I mistaken or is it only tracing atm?
I was trying to watch AXIS, and it looks like it plunges into the material
its a drop cutter algorithm just close up the lines for a better finish
the video I'm watching looks like a robotic fat chick
very much like awallin was doing
I dont know what that means. I saw it drop the tool directly into a valley without considering a block of material to clear away.
Jymmm I ran a mill like that once :)
later in the vid he clears by layer
Jymmm you had to walk into it
it's not much of a tutorial, it needs narration.
I have no sound here
It looks to me (as it stands now) it be breaking tools. Very cool start of course.
archivist don't worry you not missing anything
might work fine in foam :)
gweepprefect: Try it and let us know =)
haha.. no thanks. you first, i insist!
its up to the user to set sensible increments to suit tooling
real machines go through steel like foam
not when you slam it into a valley
Google just seems so brain dead lately
It'll be cool to see Verions 1.0
Jymmm lots of stuff never makes it there

next cutter cutting :)
are Youtube filenames some kind of a code?
archivist just random?
archivist: sure, the drop-cutter paths should not be that hard... weekend maybe
probably not random
man I'm stoked to get going here and move onto something else
making stepper motor drivers sort of sucks
steppers suck. use servos.
I was lazy and bought mine
I was extra lazy and bought good ones :)
archivist the thought crossed my mind more than once
jt-plasma the ones I've prototyped seem pretty good to me so far
jt-plasma I've made others not so good
do they morph from micro steps to full steps as the speed increases?
so I do have something to compare them to
jt-plasma nope just do full steps
1-2 phase excitation
thats pretty cool too
jt-plasma I tried some other stepping schemes and half seems like a good compromise
though there are some novel drivers out there
* jt-plasma wanders back into the thc comp to find my error :)
these are different http://www.piclist.com/tecHREF/io/stepper/linistep/index.htm
Linear? How 1970s
andypugh not how they use it
andypugh linear current amps
Maybe not, but I have rather shied away from unipolar solutions too. If there are coils in the motor I want to use all of them, all the time.
which I've listened to stepper motors enough to come to the audio conclusion with them too
andypugh you do realize that some motors are just unipolar right?
andypugh and I think the not use half the windings is when you drive a unipolar motor bipolar
I haven't done it but I have read about it
I suppose 5-wire always will be. But it seems to me you get more performance out of a given package size running bipolar
andypugh the drives are a nightmare one of these days I'll make one
andypugh really preferring bipolar is so 80s now ;)
andypugh there has been a lot of work with microstepping and sine drive
andypugh modern designs are getting fair performance out of unipolar motors these days
I guess you can run further from the thermal limits using half your coils as a heat-sink half the time, but you can only fit so much copper in a given frame size, so you might as well use it to the full.

[23:10:47] <frallzor> http://camcraftsa.com/cnc-routing-textures.htm
anyone have an idea on how to make these textures?
Im thinking bumpmapping and something that can do something with it like ArtCAM
frallzor they look like Gimp textures
I'm wonderint about implement that kinde off 3d routing http://www.youtube.com/watch?v=ByUfrz_8_NE&feature=channel
there is tutorials on how to make continiuus pattern images for gimp
MrSunshine could always hire some Pakistanis too I suppose
well patterns is one thing but to make it work like that is another =)
make the extures!
frallzor, wrap a paper around a cylinder, and start painting ... then cut it down the side and voila .. a vertical continius texture =)
huh ? :)
allmost a good idea :P
paint, scan, make vectors :P
it would work ...
frallzor, but still, there is tutorials on how to make stuff like that for gimp
oddly I thought the Romans made it first and famous
