dont know, the eond of the video says plans available, but when you check the site no plans are available but he's making kits
and they aren't available yet

crikey i gotta make a life-sized version
fenn: whatcha talking about?
the air boat thingy
* alex_joni is tired
fenn : OKEY! You ride in it, I'll fly it from the RC =)
fenn : JUST HANG ON FOR DEAR LIFE
I won't kill ya, but you just might wish you were dead =)
or the best damn roller coaster ride you've ever had!
* alex_joni goes to bed
ya know, it's a real bitch grating frozen cheese! lol
Hey Jymmm, is Alex going to be back?
Is anybody using Quadrature instead of step/direction?
quad is great ! about 4x the speed of the step/dir driver because there are no problems with setup and hold times... you can move each time through the emcmot driver...
I am using quad drive with my shoptask and tmg driver system... let me know if you need example configs.
hey jymmm... just back back from a Canada Party.... some good scotch whiskey was enjoyed by all!
LawrenceG Ah... Happy Canada Day!
just in training for July 4th!
LOL there ya go!
you gonna be around for a while?
should be for a few hours.... may give up and go watch tv for a while...
Do you have skype installed?
trying to test yours out?
too bad... works well for shooting the breeze
I am using a usb headset... very easy... doesnt mess up the normal linux sound card stuff
Ya know, I'm not really a USB fan too much.
I had a good chat with les a few nights ago.
ah, very cool.
I know what you mean about USB... it took over 10 years for pc support to kind of work
it's all the polling involved... I still have to use pure UART rs232 serial port for things
the power over ethernet stuff would have worked better.... no new drivers to write
Even when I bought my laptop I made sure it hade a serial port
I remember hearing about that, never saw anything come of it.
My old laptop has both serialand parallel.... very useful... I even use it to run emc on my mill sometimes... just plugs in
I have serial, parallel, usb, and firewire. I think I'm good to go.
on my laptop that is
even has a built in fdd =)
about the pnly thing that I have seen with firewire is some of the video camera stuff
Thats what I use it for... I have a digital video camera. The only negative thing is the transfer is real time.
oh and the fact the tapes can hold like 40GB
man... I made a pot of curried tomatoes for dinner .... it is HOT..... I think I need to go find the suntan lotion
salt baby, salt.
I love currie, hate tomatoes.
too bad..... I think I must be half Italian... love tomatoes... mybe the other half is indian because the currie sure is good as well
kind of a quiet day on irc today
I think it's the acidity in them I don't care for, becasue I love spaghetti, pizza, ketchup, etc.
It's been kinda quiet all wekk
guys must be burned out after the cncfest.... sounds like they slaved in the heat...
and probably got back logged with stuff as well.
do you do 3d stuff by chance?
no... not on cnc.... used to do a lot or 3d scanning of logs and boards in the sawmill industry.... still trying to figure out how to move some of that to cnc applications
I tried doing my house plans in 3d acad..... never could get the roof on top of the walls
now why woudl you want the roof there silly?!
it looked good to me, but the building inspector would have made me build it according to the plan!
I want to drill holes at 45 degree angle by turning the head, but someone said I would need a 4th axis instead adn that I would need a CAM that supported that.
it's only 3 axis, I just need to simulate the 4th
if its just a few holes, you could probably do the hole cycle by hand in gcode....
a few hundred holes, in a grid pattern. Basically it's to make a thread spool holder.
does your whole z axis tilt... like a bridgeport head or do you have to move x,y,z all together?
LawrenceG I'm gonna make it tilt http://k2cnc.com/Picture/KS-2525gallery/pages/Pic%20cnc%20router%2025x25%20(7).htm
seems like you could layout your x,y grid of holes... then calculate an offset for the y value to compensate for the head angle.... z axis move would just have to be a little longer
When I ordered the machine, I had the gantry clearnace increased as well as the Z travel. Hopefully It;ll ship next week.
I am assuming you will be using an endmill for drilling not a standard twist drill
endmill, router bit, something along those lines.
looks like a nice clean design

They do use roller skate bearings (ABEC7) for some things, but I just couldn't build one myself in cost or labor (out of mdf no less) for what they were offering.
I had bought some of the exact same bearings they are using, and even when I toss on a 20lb bar, it rolled smoother that water on glass.
plus they have a 15 day money make guarntee
impressed.... what kind of $$
[04:29:15] <Jymmm> http://www.k2cnc.com/KS-2525_detail.asp
that's what I ordered + the mods
the design for the linear bearings looks interesting.... I have been trying to figure out a simple system along the same lines
are you familiar with the "c" channel used for mounting electrical equipment... its a heavy gauge steel form. I want to use it to enclose the drive rod (3/4 ready rod) and to run the bearing on
it is quite rigid and cheap
the channel that hanger are connected to?
yes... about 1/8" thick and about 2x2" with one face open
just watching vides of your machine...
yeah, the videos aren't all that great imo
oh, they got more videos up there
LawrenceG: That stuff is called 'Versa-Strut' around here.
Hi Jymmm :)
* Phydbleep has been busy fixing other peoples problems...
well I can hand you mine if a cargo container if you like
Does it need 3-phase power?
nope, mor elike 3 floors of lawyers, bankers, and one small diet soda
Send that container to to the bottom of the sea. :)
hey do you use 3d CAM ?
What do you call 2000 lawyers on a sunken ship?
sharks out of water?
Nope... Either "It's not enough" or "That's a good start". :)
What's the difference between a lawyer and a hooker?
one screwing feels good?
The hooker will stop screwing you when you're dead...
Shakespeare had the right idea, but he could never find a cannon big enough to get them all in...
I love 'Pimp My Ride'
*burns a debian iso*
how do I see how much space a given folder is taken up via the cli?
(if you do it in the folder)
du --max-depth=1 -h to see how much all the tings in a dir are using
whoever that made the debian (3.1) release must be stupid.
ncurses dev isnt included, and the kernel does not ship with a driver that works with my internal card..
what do you mean by "isnt included"?
and there are no kernel sources included on the first cd on the set..
so you cant see stuff as it tries to boot?
I cant grab the kernel off the net...
without a network card..
this is during install right?
and I dont feel like going through make config..
so it installed ok?
so just apt-get ncurses-dev then
where should I get the ncurses from?
just use the usual apt-get ??
oh, they are not included on the cd.
and I dont have any network card working yet
no network? coo . thats bad
but not a pronblem
not really a problem though
they probably are on the CD
no, they are no on the cd..
it's on another cd of the set that I dont have..
get a network card working
they included gnome instead of kernel sources for example..
d/l the ncurses-dev .deb and install it
I'm still unsure why yu want to re-compile the kernel though
to remove 99% of all modules.
and to get the network card working..
on a 2.6 kernel?
going to upgrade it to 2.6 in just a moment..
just run 2.6 and its all modular anyway
* anonimasu sighs
I should install slackware again.
not really, the only problem is that the graphics card drivers comes as rpm..
and the rpm2tgz does not work with the packages..
hm, they seem to work pretty good..
is there not a pseudo package for it?
not htat I've found..
I dont care what dist I run really
I could run fbsd for all I care..
have you asked on #debian?
so I can get a RTFM slapped in my face ;)
oh well ... thats what I'd do ... ask
it's not a problem..
I am just a bit pissed why they couldnt include the devel stuff on the first cd of the set..
gnome > all
id be suprised if they included ANY devel stuff on the first CD
ive never needed a set of cds anyway ...
always doen 'net installs
stick the 'net cd in
well, it's stupid.. being without devel stuff cripples the system..
come back a few hours later, all done
I'll just grab ncursess to the usb memory stick..
but well, annoying.
* anonimasu lost a coke bottle somwhere
I can mess with this another day
I am going to stockholm to see black sabbath
the reason I need the drivers is because I want hardware accelerated X so I can play games when at lan parties with friends :)
anyone have issues installing firefox on the bdi?
seems to give me GDK warnings, and I can only run firefox via sudo ./firefox
alpha is now known as alpha_emc
trying it now using the automatic method.
nope. no go.
* A-L-P-H-A slaps alpha_emc around a bit with a large trout
hm, I wonder where jmk is..
I would have loved to hav a talk about jog wheels.
* robin_sz istrying something difficult
I'm trying to buy someting called a 'lamp' ...
what's a lamp?
a glass thing, that takes electricity and turns it into light
seems to be difficult.
are you looking for a hard to find type?
48mm, 24V 20W halogen reflector
what did it come out of? is there a part number on it?
ahh found one!
right, lamp ordered
oh wth... AMD64 mobo STILL only support MAX 2GB ram *sigh*
tomorow, I get to play with the 2nd CNC laser .. see if I can get the motion systems up and running
big AC servos
might be an EMC candidate even
* anonimasu just had a nice discussion about self auditing systems..
the servo card will be the problem I suspect
yeah, the tp :/
I thought the to was fixed?
tp was fixed?
there's a candidate I think..
damn, I wish I had time to learn the math
to be honest, without a working tp, its not viable is it?
this machine is much slower than my 'big' laser .. so wont need any great tp
just line-to-arc and line-to-line blending
at slowish speeds
slow ... 10m/minute
* anonimasu slaps robin_sz
I mill at 2m/min
the tp will break at thoose speeds.
well, its not an EMC candidiate then :)
the tp wont support bridgeport speeds..
whatever that means.. but 10m/min is fast..
nah, thats slow ..
this is a 1977 machine
hobby speed wise..
well, sure .. but if I wanted hobby speeds, i;d use hobby software .. emc is 8supposed* to be pro software
* anonimasu nods
its currently running on a 6502 based controller ...
but its clunky
surely emc can outperform a 6502?
sigh .. oh well, you are sure it wont perform at 10m/minute?
you should have a talk with les..
he knows.. :)
I am not sure since I havent been running at thoose speeds..
yeah .. but i thought progress had been made?
my box cant crank out pulses that fast..
not that I know of..
this is real servos,
no pulses needed
I have real servos.
but no real drives.. & servocard..
saving up until the tp is fixed..
and galil servos
that leaves ..
you think this will run emc1/2? outpost.com search for 4199563
I'll be off for a few days..
LawrenceG: Are you arround ?
only if he sits on his butt all day
* robin_sz ponder what to do ...
the options for making big ac servos do what they are told are limited :(
LawrenceG "Imperator_ stood you up!"
sorry, have found the information i was searching
kind of a slow day here... watching some guys build motorcycles on tvtime
LawrenceG L I can only watch that for so long.
i searched for the RS422 driver used at the breakoutboards for the mesa card
"Orange County Choppers" ?
occ it is
Fun show, if you keep the sound off :)
you get your card ?
(the dialogue is pretty lame)
I did - no documentation, just a card in a static bag
Haven't had the chance to put it into a machine yet
Jymmm, you may want more RAM in that computer, but it looks OK to me otherwise
hm, we tryed to phone to mesa yeaturday, but nobody picked up the phone
there could be a problem with parallel port drive strength though - you should definitely get a breakout / buffer card
odd - they answered my call :)
they shipped the next business day as well
nope - a week ago
What time of day did you call them?
Jan tryed it
he is the other one working on our project
don't know which time he tryed it
This is a holiday weekend - they may have been off work early (or not in at all)
probably off work by noon.
is next monday is a normal day ?
no - that's the holiday - Independence Day, July 4
so we have to try on tuesday
I'm working at the moment on some breakout boards
1. 4x Counter inputs with RS422 drivers and 4x (2x Limit and 1x Ref Inputs with optocuppler)
2. 4x DAC out and 2x relays 2x Input for each DAC output (for enabeling the servo amp, and reading back amp errors and so on
3. digital IO card with relay outputs and optodecouppled inputs
SWPadnos you think that system is faster than Celeron 366? (I have no clue on AMD cpu's)
I don't think AMD has sold a CPU slower than a Celery 366 for the last 5 years
The Athlon 2200 will be roughly like a P4 2.2GHz - hence the 2200 rating
(Sempron2200 - maybe a little slower, since it has less cache)
SWPadnos Ah, ok. So if I bump it up the ram, do you think the onboard video will be an issue?
nm that one,
It's $150 on sale
I'm not familiar with those SIS chips - I think the video is a separate chip, but if it's in the chipset, I'd steer clear
(my machine has a C&T chip on the mainboard, so it's a slightly different story, though it does use main memory for the video chip)
gotta run - working with the wife in the garage :)
SWPadnos is now known as SWP_Away
Uh oh.... DONT LET HER THROW AWAY ANYTHING!!!
Holy Shit.... yahoo auctions are now completely free!
just fine :)
conducted an interesting experiment today
Has alex_joni been around today?
and swpadnos though
and Imperator ...
thats about it ...
oh, we always wanted to know ...
just how thick a piece of steel a .223 rifle bullet would go through :)
well ,, we still don't know ...
but .. its "more than 8mm" ;)
so much for kevlar:)
kevlar vests will save your from handgun rounds
but a rifle paks 5 times the energy
anyway .. it creamed through 8mm steel plate .. no problem.
Thats for sure. I shot a friends HP rifle at a sand pit a couple of years ago, couldn't hear for 3 hours after. It was kind of exilerating though.
Hey robin where in uk are you?
bpmw_ is now known as bpmw_[A]
* bpmw_[A] is now away - Reason : Putting roast on BBQ!
robin_sz: try putting two 4mm plates with a sheet of styrofoam between them
fenn: 'k ...
How do you make yourself as back?
i want a written report with photos by tomorrow morning
might be tricky
how thick styrofoam?
robin_sz: use the blue foam insulation like for houses, it's usually ~1cm
dunno if it will work.. but i wanna find out
did you see that report on the dead M1 tank?
no you said something about it though
thought it was a battlefield laser?
the hull is 10" thick ...
nah .. HEAT round ..
A rail gun will go through that! easy
amazing .. drilled a 7mm hole through 10" of armour
rail guns are not exactly portable
Neither are lasers powerful enough to do that!
well sure ...
but they exist ...
dunno if battlefield rail guns exist
the battlefield lasers are scary ...
gas dymanic lasers,
I'm sure there are alot of things out there that we may never know about!
consume around 0.5 tonne of fuel per shot
heh how many hours does it take to recharge the capacitors?
Robin just curious, do you read Jane's?
fenn: none. it doesnt have any. It basically a rocket motor with mirrors strapped across the cavity
bpmw_[A]: not recently
gas dynamic laser ...
point me to a tutorial on gas dynamic lasers please
bpmw_[A] is now known as bpmw_
[22:43:50] <robin_sz> http://repairfaq.ece.drexel.edu/sam/CORD/leot/course01_mod11/m1-11f18.jpg
So does the laser guidr the rocket of actually fire it?
in a gas dynamic laser?
you know how a laser works?
do they add thorium or something that glows to the gas stream?
two mirrors across a cavity
and the cavity has highly energized gas
bouncy bouncy go the electrons
zap goes the light
well, the hot gases in a rocket motor are active enough ...
so you just strap some mirrors across the cavity
fir it up
and zap your enemies
wow that simplifies all my evil plans significantly :)
insane power levels
like, severall megawatts
for say 2 seconds
Thats alot of energy
they haul 1 tonnes of fuel in a bowser
and chew it up in 20 shots
Whats a bowser?
[22:53:19] <robin_sz> http://www.detnews.com/pix/2002/11/09/laserwp.gif
notice the "exhaust" on the laser building
Hey that pretty cool!
cradek, you there?
Hey Robin do you have any experience with Quadrature?
cradek, I got some new drivers to test out but they wont work on step/dir only quadrature.
quadrature? for drives?
we gave up on that .. I did have it going on emc ...
ya inputs are CW and CCW!
but I got confused as to which drivers supported it and which didnt
* Routine to compute and output the phase drive bits needed by quadrature
* phase stepper drive systems like the TMG (The Motion Group) electronics
seems steppersegmotqueue doesnt ...
emc1 supports it with STEPPING_TYPE 2
cradek: in freqmod and steppermod?
I'm on emc2
at least freqmod
bpmw_: I don't know squat about emc2
read the docs ;)
I used it briefly on freqmod
It supports up to 8 pulse generators. Each generator can produce
several types of outputs in addition to step/dir, including
quadrature, half- and full-step unipolar and bipolar, three phase,
and five phase.
but couldnt get it to work with segmot
if the comment is to be believed, there may be support in emc2
What docs, only ones I can find are for emc1
the documentation is written in C
sorry, that's a smartass way of saying there is no documentation, you have to look at the code
jmk documented some HAL stuff nicely
OH. I guess I'll have to wait for jmk.
in core_stepper.hal, change the line loadrt stepgen cfg="0 0 0"
to loadrt stepgen cfg="1 1 1"
oops, maybe it is 2 2 2
alex_joni, gave me some instructions last night on how to change hal and pinout but something wrong. getting error trying to start emc
now you tell us
what's the error?
HAL: ERROR: pin "stepgen.0.Cw" not found
the two bits are probably named stepgen.0.PhaseA and stepgen.0.PhaseB
Thats what alex said to call them, but I went for Cw and Ccw. That could be the problem?
besides your names making no sense for quadrature encoding, you can't call them whatever you want since they are outputs from the stepgen module.
bin/halcmd show pin | grep stepgen
I thought since I did newsig XCw bit I could name them anything!
Ok, I will change name as was originally suggested and give it a try!
you will need to use halcmd if you want to muck around with hal
great, good luck
fenn, just make a copy in text editor and seems to work fine.
Ok, thanks for the info. Have to go and check on roast. Bye for now!
