don't you just love the phrase "like Mack 3"
JT-Hardinge: dont forget to dose em up on coke and lollies before the trip back
especially the red ones.
Hey kids, want to try some Red Bull?
If i were a kid I wouldnt drink the stuff
tastes like crap
It's good with Vodka
OK, better to say it's _effective_ with Vodka.
say goodnight Gracie
The US Government has declared a bunch of high caffeine - high % alcohol drinks dangerous...
OK, I really should know better than to stay up documenting untested software on a work night.
jthornton: It is, but I don't need that much power/noise ans thought I might be able to reduce it by doing the lower voltage thing.
* Valen needs a spindle
~2.2-3Kw or so
not heaps of speed
would compiling a real time kernel for every day use be worth it?
if the alternative is an ubuntu binary real time kernel, probably not
unless you need something that is not in there
is there a down side to a real time kernel?
I hear multimedia distros run low-latency kernels. jackaudio.org uses one, I believe.
err... not what I meant ;)
there are actually a few realtime frameworks for the linux kernel i think
Jacklab was what I meant to type.
but it is no longer... :(
Seems working for me :D
Hello... Someone know how to easyest solve move like 'G0 X[x-5]'
.. without to goes in incremental mode
is there some variable storring curent x and y?
I sometimes set up a variable just for the purpose, but often far simpler to change mode move and change back
As I know that doesn't work with G92
I just seeking how to introduce offset for all when I turnon the camera and want to have correct coordinates.
seems that the only way is to store with G28.1 or G30.1
Saturday here and the kids and grandkids are on the way over to grandpa's house
yea, I need to go shut down the shop so we can play
Sounds like fun!
I can use any of these for an Axis encoder? http://www.industrialencoder.ca/products.php?id=26&PHPSESSID=da0b0c3c8ea1ddce8f7a876e2e96edfa
they are Absolute encoders
not at this time
your best bet would be to send one to SWPadnos and hope for the best. he seems interested in doing that lately.
cradek: the video you just posted - Did you just make that>
umm are you ok? :-)
heh - the max milling the inside thread
yes just the other day
sunday I think
it actually works pretty well...
only incremental encoders are supported, eh? I can work with that. They are usually less expensive anyways ;)
I don't know of existing drivers that work with any absolute encoders
people just use homing with switch and index pulse - you are right they're sure cheaper
ehats the imperial unit for 'lpm', gph?
whats the imperial unit for 'lpm', gph?
Hello... Need help! How to move machine for some value but to keep DRO coordinates same. I was playing with G92 but without success.
explain what you are trying to do
I had cam fixed in spindle with y+63 offset. When I turn cam I want to all coordinate reffer to camera crosshair instead tool.
use a tool offset of Y+63 ?
With cam I just want to set tool offset for new one.
So I think that G92 offset can be better
just didn't find solution.
I don't understand what you mean
Let's see like example to be clear. (my english isnt so good)
The example is nonsense but just to clear.
I do g0 x10 y10
then g1 z-10
now I have hole for example at x10 y10
Now I turn on the camera and wan't to move machine for (known camera offset) but want to read on DRO stil x10 y10
and to se hole just under the cam.
Is that understandable?
yes, load a tool offset
I think is easy if I get something like g92 x[x+63] to work. But that simply doesn't work
g43 h[camera tool number]
g0 x10 y10
hole is under camera
I try with g30.1 to save position but is in machine coordinate so doesn't work too.
cradek ok that's work. But what about some shortcut. the g0 x10 y10 is simple but in real the number is longer and don't want to make some typo.
you want to move the feature that's currently under the spindle to under the camera?
and back too
g91 g0 x63
g91 g0 x-63
that change DRO
g43 h[camera] g91 g0 x-63
g43 h[camera] g91 g0 x63
g49 g91 g0 x-63
i'm getting - command (EMC_AXIS_HOME) cannot be executed until the machine is out of E-stop and turned on
when trying to do homing on X axis
is the machine out of estop and turned on?
what is estop? emergency stop switch?
F2, I believe
:P press both, lol
there are two red button at the top left. one is power and the other is eStop.
same keys in tkEMC?

thanks will read
'a typical session' is not very detailed but it has the steps you need
cradek: have you used your 4th axis on the jr yet?
cradek: have you used your 5th axis on the jr yet?
cradek: your video showed 5 axis
Jymmm: jr is my big machine - the 5 axis is a desktop size play machine
cradek thanks seems taht works
error gone, it does not seek home yet
too slow moving..
is there going to be a emc-fest in 2011?
I am about to plan my holydays :)
Good Evening from Germany
temperature now Below Zero Here
hello I just installed ubuntu 10.04 followed with EMC2.4.5 and I have this error message: http://pastebin.com/QqMsUEEC
I checked limits.conf and it does contain the line * - memlock 20480
you installed the 10.04 from linuxcnc.org?
so you compiled your own RTAI kernel?
seems no RTAI at all.
i ran the sh script
didn't want to use the .iso from the website?
tried running it but it failed
in fact it seems the computer i am using hates ubuntu live cds
Defhammer: dont use the Livecd install from running livecd
install from the first picture not from running livecd distr
problem is that APOD NOLAPIC NOApic cand be issued to GRUB as they run already
i used the ubuntu alternatve install to get the system running through a different computer
to switched HD
then switched HD
you shoudt install it on the system it is soposed to work with
whats the problem low RAM ?
it's got 512MD
it would seem the BIOS is not liking the install process
so press F& at the start and switch on all OFFS it iss showung You Nolapic Noapic ...
I can try it, but the thing is the livecd will run on the computer it just fails during the install process
you dont need this fine power issues as you on a RTI
ok I will do the no apic option and see if that works
I will try to reinstall the OS using iso from linuxcnc.org
I will be back in a bit
by till tomorrow
If you have a 4" hose and need to filter the air, how much surface area do you need to not impend the airflow too significantly?
Well, the intake for the filter is 4", the medium is carbon pellets.
good evening all
didn't think carbon would do much with air
would also depend on how much air your pushing through it Jymmm
any advice on spindles?
we need around 16000RPM or so
and around 2-3Kw
but we would also like to be able to do lower speed stuff
I hear those chinese ones aren't much chop for actually cutting metal
Valen: I hear that usually it's the ball bearings that are cheap... there rest is just ok.. Electronics are sometimes flacky...
I'm worried if we got one we wouldn't be able to upgrade the bearings to something big enough for metalworking duty
Valen: for the money you can always try :) But indeed... might not be good for metal... at least not teh ocne I see for 400USD on ebay
thats what I was looking at
if they didnt say "please dont cut metal for long times" in the ads it'd be a good start lol
hehehe... I know people buy them for woodworking with reasonable good success
I don't do metal working, so I am not sure what the reviews are
* Valen wants to cut stainless
