it's human greed and fear that's the problem
i know plenty of businessmen who have overcome that
real, tangible factors
if you're convinced you are right
put your money where your mouth is
and start a business
and find investors
i dont have any money, and investors are not going to invest in it because nobody's done it yet
and overcome the obsticles, just like our present incarnation of the IC engine did
oh you are such a bullshitter
you can't do it, okay fine
seriously, why would anyone invest in me making some engine?
oh my god.
the same reason people invest in any new, disruptive technology
they don't invest in new disruptive technologies
i know you really like to stick your thumbs in your ears and go "lalala
but they DO
and i've seen it
and i work for folks who have had such things done
and invested in due turn
and it's paying off nicely
fenn, just stick to your armchair and let people discuss a nice bit of machining
instead of attacking any random link you see
with fanatical bullshit
it's not any random link i see, it's a glorious example of wasted time
that's the arguement every fanatic makes
for any piece of technology they don't like
if it was really a waste of time, it wouldn't have gone anywhere
and it's your own, intrinsically personal fault
for not being able to cope with that
if it didn't work, it's an experimental result that will help design something better
if it's a proven design, well, what does it prove? nothing
you make me laugh, man
and i can see this won't go anywhere
maybe this guy is doing all kinds of crazy experimental stuff in his engine, but i can't read swedish
was the machining
look an engine! http://www.nvbackflow.com/engines/
isn't it beautiful?
yeah, that's a lot of hard work.
nice engine yes
his buddy has a gorgeous rolls royce v12 miniature, and his toolroom has a 'cortini' mill , tabletop cnc from the 1960's, very sturdy. cortini made machine for schools, even a little edm.

here's a video you guys may enjoy
the good part is the middle of the vid
[00:28:07] <toastyde1th> http://www.youtube.com/watch?v=xmS3LgfdT7E
why does it explode on the first hit like that?
they hit the dies with this real thick grease, looks like engine sludge
and on the first hit it explodes from the compression/heat
the execss explodes, that is
there's a thin film that stays around
looks exactly the same as the 1904 video
ever seen someone run a mill with an scale of 8 pulses per inch ?!
thats what I said
Ziegler: sounds painful
does he/she use a normal switch and a toothed wheel?
I was trying to walk the guy through axis config
he has an 8 tooth / inch belt
oh but that dosent mean 8 pulses per inch
you still have 2 deg per step.. right?
directly on a stepper... that does 200 steps per rev
ah.. .he never mentioned the size of the wheel
[00:59:09] <jmkasunich> http://www.youtube.com/watch?v=7fuHkxNPOLo
ok... 20 teeth on the wheel
so now thats... 160 pulses / inch
jmkasunich: i like how it sticks to the top die and how he gets it out
damn, it stuck - just whack on it a bit
i just left jernberg forging after fixing an edm there, hot forging big universal joints and harley brake hubs. not anywhere as clean as that video
[01:04:34] <jmkasunich> http://www.youtube.com/watch?v=XUg-6CN4gkQ&NR=1
heavy bar forging
(200 pulse / rev) X (1 rev / 20 teeth) X (8 teeth / inch) = 80 pulse / inch
is that right?
200 pulses = 1 rev of a 20 tooth gear, which is running on an 8 tooth per inch rack?
sounds right to me
pretty coarse, this isn't a machining application I assume?
Im helping a guy set up his mill
im scratching my head too
dunno how its going to be of any use
can emc even handle an axis scale of 80 ?
I don't see why not
is that 200 step/rev or 200 pulses?
emc outputs a floating point position to HAL, so it can change by .00001 at at time if it wants
whenever the commanded position has moved by 1/80 of an inch, stepgen will send one step pulse
200 steps / rev.. but he is whole stepping
I just want to see what the heck he is trying to do
woodworking maybe ;-)
log cabin parts
he's going to have some rapids...
tomp actually here?
do you know the part numbers for yaskawa servomotor connectors
the hi density 4 row thingy?
wait, gottas lok it up , its in the pdf from automation direct tho
and the mini centronics thing on the drive
I saw a dead BP with Textron stepper CNC and 30 NMTB spindle... I would have made an offer if I had space for the thing.
not sure on Series - but it hand the uber heavy knee and table with full steel way covers
the series II are a lot bigger
did it have box ways on the table?
must have been a II then - cause I used to run the lighter version
I think it was box - not dovetail
the series I only has a tiny travel
actually, the series I doesn't need steel way covers either
someone started to try and get it running again - but didn't get far, conduits for the limit switches were just hanging...
I haven't gotten far with mine either
I could tell it was stepper - had those old ,onster steppers with the huge cast fins...
It did have a fairly new Kurt Air powered drawbar unit on it.
the great majority of BP CNC that you see for sale are stepper
this one was just sitting in the corner of a diesel emissions testing facility.
that's where most of them are
sitting in a corner
eric_U: >not< in automation direct pdf, must (might) be in yaskawa pdf...
pretty sure they aren't in there, most companies will not tell you that
and I looked in yaskawa
I can find the one on the drive easy enough
[01:40:00] <tomp> http://www.yaskawa.com/site/dmservo.nsf/link2/MNEN-5CLKGN/$file/TSE-S800-15C.pdf
see section 3,8,8 it has 3M mfctr numbers availabe from mouser
ServoPack side 10236-52A2Jl from 3M
cable side 10136-300VE from 3M
cover 10336-52A0-008 by 3M
those were for 1cn , 2cn also is listed
I have some of the small ones
and you can hand build the expensive data cable , i made a firewire to db9 to usb adapter to save a couple dollars. the db9 to usb allowed my serial-port-less laptop to talk to it
what about the motor side connectors?
anyone knows how to use "comp" tool of HAL?
eric_U: also mouser, also same manual, i got right angle 'military' type. I think i had to fiddle the insides a bit for some reason... maybe i removed thiers and added mine for (again) cheap
you have military style? Mine are plastic
scrolling down to section 3.8.8
eric_U: yes, green hard die cast, split, keyed and ring screwed down, xtra heavy duty connectors.. thats what i replaced thiers with aka 'canon' gotta go, that forging house was filthy, and i'm gunking up the keyboard :(
thanks, think I found it
70 whole cents, beats $26 for the connectors on some of the other motors I have
I need some help finding the 'comp' tool for makeing HAL components in EMC2
SZTAKI: is it in ~/youremcinstall/bin/comp ?
and the howto is http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?HowToWriteNewHalComponent
and examples at http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?ContributedComponents
Ziegler: my gEDA comps need a bit o work still, but i did write a python script to generate hal files. its crude but can grow into a tool. i have to find a place for methods in the gEDA item, and some way for the user to spec which threads ( or rely on text editor hacking :(
hmm, jepler's comp is a python script with a parser... spiffy, like what i want for the netlist to hal xl8r
eric_U: maybe mine were different, i had the 3kW motors
and the AD connector was straight, so added maybe 6 to 8 inches with the cable bend... thus the change to right angle cnx
argh I'm confusing the AD motors with the tiny SG yasakwa's... never mind

hey... anyone have any ideas on how to tool path a point cloud of data. My initial thought was to convert the cloud to 3D and then load it into a CAM program. Is this the way to do it, or am I over thinking it.
are they in a grid?
yeah... every .002"
wait no they are not
but what if they were?
just G1 along the grid
thats simple enough
if they are very close together, be sure to use G64 Px
oh? I will have to look that up
it merges redundant points (like those in a straight line) into longer segments so it can go faster
oh thats convenient .. I assume the Px is to specify distance to ignore
[15:38:47] <Ziegler> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TrajectoryControl
nice graphics on that page too
can anybody give me some help?
where can I find the 'make'-file for my .comp files?
you compiled emc?
re ini files... what does [Display] Cycle_Time do?
Ziegler: if they are not on a grid, there are softwares out there which convert point cloud to mesh
mesh which you can then load in CAM..
if SZTAKI comes back, someone please direct him to http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?ContributedComponents#How_to_compile_and_install_a_component
which should answer his question.
jepler: tomp already directed him at that page
alex_joni: yeah but not with that anchor .. maybe he wasn't interested in reading the whole thing
a clear case of RTFM
a good day at HGR.... 8 pieces of THK SR20 linear bearings for $40
no rails, just the bearings
(they're captive ball ones, so no balls falling out)
seem to be in excellent condition, they were used somewhere clean
also got a SR45 bearing and 400mm long rail for $20
so I could build a machine!
4 SR20s for X, 4 for Y, and the SR45 for Z
heh, thought you had enough machines?
yeah, just what I need, another project to start and not finish
also, 3 carbide face mills for $30
2.25" 8 tooth, 3.25" 8 tooth, and 5" 15 tooth
hmm.. reading on RTnet.. not really excited
External event -> interrupt -> stack down -> wire -> stack up -> signal on
that takes 60 us.
well.. it includes 2 * latency in the PCs (that's about 30-40us)
otoh you don't need more than 10kHz servo updates (or seldom need more..)
that means 100us if my math is right
* anonimasu nods
[20:25:04] <anonimasu> http://www.aoc.nrao.edu/events/Real_Time/fieldbus/fieldbus.pdf
a 60 byte package takes about 6usec to travel
ah big packages too
that gets much better..
anonimasu: EtherCAT missing from that paper :D
* alex_joni has a thing for EtherCAT
well, I dont have any hardware that uses it ;)

Are any of you using xmms for audio playback in 6.06 ? If so does the EQ change the sound any? I can't tell any difference at any setting. I'm trying to find an eq that will work in 606 if anybody has a suggestion
skinnypuppy34: did you enable the eq?
pretty sure, eq window open and on highlited
hmm, sounds like you did it all.. worked for me though
ballance and volume work fine.. wonder if I am missing some alsa piece
learning blacksmithing looks interesting
but i question the practical applications
skinnypuppy34: I think it's done in software before alsoa
My neighbor does a good bit, power hammer is cool ... and forging billets together with anhydrous borax is pretty cool
is it profitable?
If you can find some one with excess money that wants the real thing
rather is it economical to do so nowdays..
ah.. art not practicality ;)
He did a decorative gate job recently for a few grand
Forge welding and brazing is about as practical as it has been for me personally
i could se getting a power hammer and using it for closed die forging
for small forms
Yes have thought about such ... we've got an airram hammer with about an 80lb ram with removeable dies ... it's not really my thing but I hang around when the metal is hot ;o)
toastydeath: this is for you: http://icanhascheezburger.files.wordpress.com/2007/11/funny-pictures-halo-dog-pew.jpg
in hal file how do I inert Y axis direction?
Ziegler: negative SCALE
haha i saw that
cant be done in hal?
Ziegler: sure.. but then it will jog on the screen in one direction, and the machine will go the other way
you can invert the dir pin
Can that be done throught the gui for mirroring by chance ?
setp parport.0.pin-04-out-invert 1
right I am looking to invert y direction
or soemthing like that, you'll have to look up the pin name
setp parport.0.pin-08-out-invert 1
net zdir => parport.0.pin-08-out
alright out to test the machine
how's it going ray?
Not bad. Got a poor hold on my dialup today but...
Trying some stuff on Ubuntu 7.04 I think.
How are you doing there. Is it winter yet?
yeah, feels like winter.. had a little bit of snow today (it melted shortly afterwards)
We've got a couple inches on the ground.
Lake is still open but should freeze over next week sometime.
then it's iceskating time :)
I get a sore butt just thinking about trying that. I'm not very coordinated on skates.
You guys have done a great job with the new release.
you tried it out?
Interesting stepper configurator. Still klunky but a good start.
Right been using with a Sherline mill and a couple Smithy mills.
cool.. let us know if you find anything
You bet I will.
Sherline is talking about upgrading to the latest.
yeah, they're a bit behind :)
btw, I'm planning to do a new version when 8.04 comes out
Way back but Joe says EMC has been good to him.
that'll be the new LTS
Lots of machines sold with it.
rayh: glad to hear that
new LTS -- 6.06?
On the CD you released the other day?
the CD I released the other day only has an updated emc2 on it
along with regular Ubuntu updates
but it's still 6.06 Dapper Drake LTS
the next Ubuntu version 8.04 Hardy Heron (release 2008 April) will be Ubuntu's next LTS
so I'm planning to get emc2 going on that, to replace the dapper platform eventually
but so far it's only plans.. gotta see how RT friendly it will be
Good because the ending date of 6.06 is beginning to make me nervous.
When Ubuntu kills off a repository like they did recently for 5.10 it really leaves an install hanging.
I've been building trunk on that until there was a new addition for the docs. That did it.
they didn't kill it for good I think
[23:21:59] <alex_joni> http://emergent.unpythonic.net/01186407274
I don't think there is anything at the old repository any more.
And I don't see a repository at that location either.
Just the iso
[23:26:01] <alex_joni> http://old-releases.ubuntu.com/ubuntu/
it's all still there..
(just need to put old-releases.ubuntu.com in your apt/sources.list
Okay I'll try it after a bit.
but it won't see any updates from now on afaik
