You know, MicroSD cards are pretty cool... most come with mini and micro adapters so you can use them in differetn things, plus they have these super tiny MicroSD to USB adapters that are as thin as a dime...
The problem is that the MicroSd cards are small than your pinky tnail and the USB adapter is so fricking thin you cna't finder either one when you haven't seen your desktop in a few years =)
it would be nice if physicak desks hada "minimize all" button
LOL, yeah no shit... and "desktop clean unused crap" feature too
if I could undelete real paper, I'd probably store everything in the trashcan
That's kinda why I got the 4GB MicroSD cards, to store stuff on adn can still use them in cellphone, camera, etc
I think I have a 2G, but I can't find it on my desk
Oh, I think I *MIGHT* know where ti's at... brb
nope that wasn't it!

I hear tonight is both full moon and the moon's perigee
it's clear here, and very bright
it's interesting here
there's a low thin cloud layer, so I can see the moon quite well, but it has a big halo
it's not quite full yet though

hmmmm! anyone gotten any mail off the list in the last nine hours?
how's your weather up there tonight?
we've had some rain and just a bit of wind here
not too bad so far
37 with a wind to take the effective temp below freezing
weatherman is promising -7 wind chill by sunday nite
looks like it's going to be 9 above here Monday morning
yep everyone is going to need good coats .. or just stay inside.
I just sent you a pic.
It is hard to generate perspective but you are looking at a side view of a .5 endmill roughing a curve in G18
oh ... you already got it.
I specified a 0.5 rougher with 0.015 clearance
from the pic it looks like it's standing up in the vise
did you use Synergy?
in a couple of days I'll real pics (I hope) 0f the finished product.
trigger guard for an 18th century trigger guard wiht a supporting backbone that gets embedded in the stock.
Not exactly traditional but effective
Yes I use synergy
you might ought to post some info about using it to the mailing list- so that folks can get a little taste of CAD for Linux actually being there.
I have some stuff that I've done in APT. I should do the same thing
rough with .5 end mill, the two passes with .5 ballend. one at +0.005 inf 5 passes and then passed at 0.03 ea at zero.
I played with APT but got stalled. The error codes didn't help much.
I'm still pretty slow at generating tool paths with it, but I'm getting the hang of the geometry
The definition in geometry makes sense ... but how to tell it the rest is where I fell down
I've been using all kinds of different programs/scripts to get work done for cadcam under linux
sometimes I use python, sometimes apt, sometimes windows stuff under wine
I keep things I'll get to blogging and lay out some of the stuff I've been doing and other stuff I've tried.
For the repetitative stuff I use C
when you get some more pics, send them to me. They are interesting
Tried some really wild stuff where I manually programmed a zero path the used C to make a tool table with offsets.
added backlash to Z axis and really cleaned up the appearance of the surface
really? wow. You ought to put that up somewhere so people can learn a bit about using C with toolpaths
think of laying the G18 curve on the side and doing half then flipping and doing the other half.
I've thought of tilting the part 35 degrees and doing the curvature in G18 where you get to use the effective radius of the ballmill
then you can get some sfm
Oh, ouch ... predicted low for Tues nite is -7 without windchill
finally got ssh and scp running between the desktop and the shop: really handy
that's very handy- I do it here too
There is a script in synergy which I need to modify to do the same thing easily
I'm still pretty much a novice at synergy.
Mostly work in 2.5 D
I think there must be a major fiber down between here and the East or someone would have said hello by now.
you might be right, they are having a major ice storm, from the look of it
1e6 p eople without power so far
no, I hate the ice
it does a hell of a lot of damage
I have a 2K gen set to make it so I can pump water and use propane furnace
snow can be tolerated
I have fire wood here
You tend to get more ice than we do. Ice and hills is a deadly combination.
I end up just staying home when I think it's going to get icy
Try Pullman where you can walk all the way around the block uphill
I can work from home too
work from home is good
I've been working on some bike parts here all day
doing some design in Ashlar Cobalt
but sometime you have to go in and make chips
I have the Bridgeport here , so I actually sometimes make stuff here
kinda hard to make rims on a BP
ding ... just got a list email
me too, in digest form
so something is working.
I have 2 more part to bang out then I start polishing. I have about 0.001 scallop on part so they clean up pretty easily.
Should have pics posted before mid week
great. I'm looking forward to them
Need to be at my sons birthday party in Auburn tomorrow. May not make it as they keep slamming the pass closed
going to bail and get some shuteye :-)

just booted the latest live CD on my athlon box - it works.
it's amd64 (or i guess it's called x86_64 now).
probably gong to do a bit of HW shopping tomorrow. want to get a decent, recent machine for a dev box.
how emc2 usis enable amp signals
is there eny situation where single amp should be shutdonw of set to operationalö
can i use one signal to set operational all servo amps
Im planing to use logic and to add all amp enable signals together and output willbe from one output pin from mesa
I don't think there's a case when emc2 disables just one amp enable
they all get enabled/disabled together
so you can just take the amp enable from axis 0, and use that to drive all your amps
alex_joni: it makes sense that you always want all axes coordinated onec you start moving :)
well, holding pos atleast..
anonimasu: theoretically they could get enabled/disabled at different times
but currently the emc2 task controller doesn't
(the motion controller supports it)
ofcourse, but it dosent make alot of sense to do so(atleast to me)
ok thanks this helps me alot
Ican use only one output for all 6 amps
Vortex2: what are you driving?
alex_joni: 5 axis
X axis has two 750W ac- servos
all other axis has 1 servo
has two servos
sounds good .. we want pictures :)
[12:38:24] <Vortex2> http://picasaweb.google.com/jsskangas
I see you use tkemc
_very_ nice servos
how do you drive them?
I mean these: http://picasaweb.google.com/JSSKangas/CNC#5272307629589414098
those are for my metalworking cnc mill
rexroth indramat, I use MESA5i20 board for bought

fragalot: thats my akita and my frend
Vortex2: :D my aunt has 2 akita's
motors has resolvers but drives changes feedback to A and B and I pulses
right.. so resolver/encoder converter
did you use the one from pico systems?
Vortex2: also, I'd like to know if you use hostmot2 on the 5i20

due to some problems with my ubuntu installation i had to format, so emc2 is now gone
i tried to find some documentation mentioning that emc2 must be run on realtime but no luck
ubuntu has to be the only linux distro that has to be formatted in order to fix it... :p
glx51mm: you can run it on platforms without realtime but only in simulation mdoe
you can't control actual hardware
something crashed when i tried to use opencam...
thx for the tip, however i want to put back my router in action so i guess i need rtai
btw, the live cd with emc has the rtai kernel ?
problem is that running realtime i had no network or sound but anyway i'll prolly get a fix on that
can anyone provide a link with instructions installing the rtai kernel, is been a long time since i did so i remember nothing at all
glx51mm: start with the livecd
either 6.06 or 8.04
the 8.04 is newer, might have support for you network and audio
or like on my (new) system, not run :p
the thing is that i had managed to install everything successfully last time, emc and rtai in ubuntu 8
is there a way to run EMC without X?
like the DOS machines.. the system i plan on using can't really handle much
there are GUIs that don't require X
keystick is one of them
or you can run the GUI remotely
ssh -X should help
it won't have network, so that last option won't work
I meant something simular to http://wiki.linuxcnc.org/uploads/tkemc.png
but in a framebuffer or something simular
framebuffer means X
with a crappy driver
so either you use keystick (non-X), or you use one of the X interfaces
alex_joni: I mean something like what make menuconfig does in console
fragalot: are you familiar with the emc2 manual?
and i can't find any examples of "keystick" :(
alex_joni: I like this frontend of the manual better ;)
[13:35:34] <alex_joni> http://www.linuxcnc.org/docview/devel/html//gui_keystick.html
cool, so that can run in the console

how much performance do you lose going AMD over intel these days?
eric_u1, dollar for dollar or with unlimited budget?
should be the other way around then
there isn't quite performance parity though, is there?
dollar wise, there seems to be
Intel has the fastest chips on the very high end, but those are $1000+
too bad MHz doesn't mean much any more
you can buy AMD quad cores for $150-ish (low power even)
oh wait, $120 now
I was trying to decide if I could tell the difference between a quad for 150 over a dual for $60
depends on what you do
you'd almost certainly notice if you do a lot of make -J
oh. is that multithreaded?
make is multithreaded?
if they split it into UI and "calculation", then you're probably better off with two cores at the highest clock speed you can get
make can run multiple compiler processes simultaneously
that's cool, so I have to split my source code up into more than one file now?
if you want to take advantage of parallel make, then yes
my quad core AMD box compiles all of EMC2 (for sim, so no hardware drivers) after a make clean (so it recalculates dependencies), in about 20 seconds
unfortunately, I never got around to checking the quad-core Intel box I had in the same way
I could do that I suppose
we just bought 10 quad core intel machines at work
dell gave us the 20 piece quantity discount
LawrenceG: those resistors are around $7
they also have .005ohm (with the kelvin connection)
eric_u1, what CPU?
skunkworks, wow.... I looked at using some of the caddock resistors (look like to220 package or similar), canbe bolted to heatsing if required for higher powers
:) what do they cost?
in the range of 2.50... I'll look for a link
[17:57:41] <skunkworks> http://www.ohmite.com/catalog/pdf/10_series.pdf
[18:02:18] <LawrenceG> http://dkc3.digikey.com/PDF/C083/P1846.pdf
I lied... seems like they got quite expensive
heh - isn't that how it always works out?
looking at the rds on resistance is looking more interesting
the mosfets I have are pretty high.
(they where cheap)
doesnt really matter as long as current limit is adjustable.... if volatge across fet is .5v at max current, then set current limit circuit to trip at .5v
fet is already heatsinked and one doest have extra power dissipated on board
not worried :)
jmk though schooled me on how much power the package can disapate.
it sucked :)

they do show up on ebay once and a while... sometimes for a good price
at 20a that would be 40w
thats why they have bolt holes!
same with the fets... why get 2 things hot?
heh - I would assume the 20w rating is bolted to a heatsink. (knowing how things are sold)
anyone having problems with network connections on real time kernel ??
what kind of network? wireless? wired?
i am on hardy, normal kernel no problems, rt kernel no network
is the nework card recognised?
yes, i run the hardware test and it sees the ethernet adapter just fine but of course no internet
I mean huh
on network managed it says no network connections detected
i've been searching on google for the last 5 hours with no luck... u r my last hope, even posted on the ubuntu forum but not a single reply
so - when you go into menu 'system' -> administration -> network - what is there?
just a point to point connection (not connected), no wired connection appears
then I assume the card was not recognised... I think there is a 'suplimental drivers' that you can install..
* skunkworks waits for someone to explain....
u might mean restricted drivers ?
sounds right - I am not a linux expert...
neither am i :P:P
does anyone here cut lenses
or lens laps
there is a guy on cnczone iamcarrot or something like that..
well i think it's not a driver problem since i checked again and the driver loaded on both normal and rt kernel is the same

anyone bought a recent mobo and installed linux?
did it have integrated graphics?
buy! whats that
my last install was to a board with integrated video
but its not a normal board as its a touch screen computer
that makes no difference. the video controller doesn't care about touchscreens
I've done one recently, as has skunkworks
well, that's my experience, with the integrated unit I have (LCD with touchscreen in a panel PC), and the external touchscreen I have (which connects to the video controller via DVI or HD-15)
this was the Goal3+ motherboard from - uh - MSI maybe
I was just kidding, I was curious about his strange mobo
the maker here makes their own mobo
ah - that makes it abnormal, not the touchscreen :)
oh - ECS

trying to decide if that would bother my son at all
he's currently on a 700 mhz pentium 3
I'd just get an add-in card for $30 or $40
it's a slot processor
you can get very fast cards for that proce, fanless and relatively low power even
I figured I'd get a dual core processor and mobo for ~120 or so
that may be a little low
do you have suggestions?
if you want it to be usable for a few years, you should probably get something with DVI and/or HDMI output
most of the really cheap boards have only VGA
nothing specific at the moment

cant' I get sucky graphics for less than that?
the lowestcost dual-core CPU is ~$60
that one is a bit better
and the 790 chipset is a significant step above the 780
that's what I hear
also, the SB750 south bridge fixes a bunch of issues that the SB600 had
or adds feaatures - sometimes I glaze over when reading those articles
incidentally, the sideport memory is actually onboard graphics memory, so it doesn't use main memory for graphics

except i got into an arguement with the owner, and now i don't really want to work on this project anymore
so i guess the question is do i want to be involved despite having a solution
depends on what the argument was about and wether you're getting paid for it

the arguement was because he got a bruised ego
that wasn't the answer i was looking for, but ok
i don't get paid to fix the problem?
i don't get any special bonus for fixing this.
the arguement was he was wrong, and i was right, and it took three other people telling him i was right to get him to realize it
and that it took so many people shouting at him bruised his ego, and then he pulled me aside and chewed me out for it.
