man i never realized how unlevel my mill was. no wonder the coolant would always pool up in the front right corner
maybe she'll leak less now
aa-danimal-shop makes it easier to clean though don't it?
I'm stoked my first soldered up motor driver works! http://img708.imageshack.us/img708/2581/motordriver.jpg
one down two to go
na, it leaks on the floor when it pools up like that
aa-danimal-shop your table doesn't have a drain?
nice work on the motor driver!
it does, but not where it pooled up
aa-danimal-shop it'd have been nicer with etched boards next ones
hey as long as they work
aa-danimal-shop well it is working on my bench I'll see on a machine
i had to watch my cousin on American Idol, she did good
I need an alerter service so I don't have to watch a moment longer than necessary
no need to make up excuses why you're watching it, we wont judge you
I can't stand it
can't say as I've ever watched American Idol
if they used it to torture me, i'd talk immediately
but it is impossible not to hear about the show's "winners"
it's impossible to ignore, no doubt about that
but it's interesting to have a relative in it
it wort of makes me feel as if hellen Keller might have been blessed ....
I had an aunt named Helen Keller
Eric_K was she deaf dumb and blind?
not that I noticed
I haven't had a TV in years, don't miss it at all.
clytle374 sometimes I put it on to fall asleep to
i just watch netflix
but usually just when i go to bed
i canceled my satelite
aa-danimal-shop I had satelite it was great whenever the weather was bad and I couldn't go outside i couldn't watch any TV either!
aa-danimal-shop: I finished a new frame today but I was in such a hurry I didn't get pics before it went to powder coat
My dad has direct TV so I can fast forward through commercials. Otherwise I won't watch it at all.
Hi all, a G code question. What if I want to make the current location zero, execute a subroutine that ends with the position zero, then restore the location back to the original?
Is there a way to read the current location and use it to apply the offset with G92 ?
g92, then later g92.1
but if I don't know the current location what will I use for G92?
[02:31:23] <cradek> http://www.linuxcnc.org/docview/html/gcode.html
to set the current location to zero, you'd use G92 X0 Y0 or similar
then to get back to normal, you'd use G92.1
I'm not sure I understand your question, but that sounds like how to do the task you described
yes I think that is what I want So I just wasn't sure if that was how G92 worked. Thanks. I will try it now.
[02:33:49] <cradek> http://www.linuxcnc.org/docview/html//gcode_main.html#sub:G92,-G92.1,-G92.2,
here's the explicit text about how G92 works
geo01005_home is now known as geo01005

wow, no jt-hardinge all day. He must be working hard on his lathe
hmm just figured out that the fan shaped nozzle for my lockline creates less splash when the coolant hits the endmill than the regular round nozzles
and it gets more coolant!
And less chip removal too.
Anyone know when the code for the 7i48 is going into git?
Or where to get the patch?

hi from germany
i do not have internet connection on the Pc that shoud control the CNC with emc2
there is xubuntu 8.04 on it
is there a packege to install the emc2 on this computer transportet via USB-stick ?
sealive: it's more than one package
maybe that works for you
i do have karmic running on the inet pc it seams that the installing page dont pack the packiges on the usbmedia
i'am neu to linux so that all little confuses me
coudt somewone help me pass this http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#without_an_internet_connection
sealive: it probably won't work on karmic
you need emc2 packages (easy to download), but also hardy dependencies
i got xubuntu hardy on the offline pc
can't you take it online just for the install?
i downloadet the tar.gr from 2.3.3
source is no good for you
hmm.. I only have a dapper machine in reach, but maybe someone else with hardy can generate that list
i tryd no 2 days 4pcmcia cards and 6 usb wlan sticks it seams not to work out with the onlineconnectin of the pc
don't you have ethernet?
ok i will wait the mashine is running propper on winXP
ethernet ports almost always work
no here is no ethernet available
the armada500 has also no ethernet conector
* alex_joni shrugs
so i need a other pc this one did the mashine for 4jears but sdimply the dataport bit 1 went off now i do not have a X axis
and milling without xaxis is no fun
what do i have to do with this?
do i have to find this packeges manuell and copy it to the pc thats offlineß
alex_joni: my kernel is 18.104.22.168
2.6.24-16 des this wor
wiork out for me
my X and Y axel motor mounts will be soo beautiful :P
hmm, moving around epoxy while it hardens ... bad idea? :)
doesnt have to be THAT much strenght in the parts tho but still want it to stick together good =)
MrSunshine_: in general yes
anonimasu: hello, didnt you have a TNC124?
why are you wondering?
I think the 124 is the same but without 3 axis interpolation
do we need to login with all the new stuff every netsplit?
tomp is now known as tom3p
hi from germany someone from the development team in the chat channel?
or someone that can help me with a totel offline istallation of the emc2
i downloadet all the 70 packages that youri has in its list and putet it on the offline PC that is connacktet to the cnc
ther is no way to put these pc online!
why not just use the live cd?
the live cd does nead more then 360MB ram! ther is only 128mb
get more ram
get a better pc
systrem is xbuntu 8.04 hardy
it wars good enove for 4years running the cnc with win98se and nc-frs
then you could keep using it that way
but i lost now my x-axis and want to try out emc2 so i can move the x-axis to data 6/7 on the lpt
oh you're the one who's doing this because you have a bad parallel port?
that sounds like a lot of work to save extremely little money
as you get further along, if you have specific questions, I will try to help you
if the .sh thakes the packiges out of the folder then it shoudent be a lot of work
maybe this can help you: http://batmat.net/apt-offline/index.html
or do i have to install all the 70th packages manuell
isent it a way to tell the iinstall.sh that all the packages needet are in a folder?
sealive: read that url
sealive: you are asking about a function of apt, not a function of install.sh
the link you providet says only to use with to mashines as i understand but ther is only one PC
since you got the packages from the internet, obviously you have a second machine connected to the internet
he has no network
yes but there is no connection to the pc thats on the cncn
remember we dont work that way as connecting is not that hard
archivist: apt-offline talks about how to get packages from a net-connected machine to a non-net-connected machine
I am 100% sure sealive has access to a net-connected machine
(you can guess how I know this...)
someone is expecting use of a spoon
i guess the other machine is not a linux box
i both a new pc last week for 50dollars 32Euros
but there is no way to put thease mashiine online i tyd 4days using 6pcmcia cads and 4 usb sticks
i am in the outback
our town has a super connection to a provider
the router is at the townhall
i got 4ip's
and a max of 1GB/week
tom3p sings (in his head) "good morning, good morning, the best to you this morning, good morning, good morning, to you" and wonders where its from
or was used on an advert as well
by till i got rid of this problem
hmm my machine has been freezing up lately.
hm, skf sells open frame motors...
the bearing company?
open frame ?
to build in your case
60krpm shuld be penty enough for most stuff? :)
i guess open frame = http://quality-deal.com/osCommerce/images/MOT-012.jpg
a bit bigger though...
hmm, wtf .. magnetic bearings? :)
can they hold cutting forces also ? :)
in this case open frame is just the windings without stator included
and a 50mm hole in center or
something lik ethat
anonimasu, but how are they against forces? :) the bearings
MrSunshine_: I didnt look I assumed they were $$$$$$$$$$
when you are spinning at that speed, inertia of the cutters mass is probably most of the force
hm.. you think so until you start loading the cutter :)
[19:02:01] <anonimasu> http://quality-deal.com/osCommerce/images/MOT-012.jpg
open frame work as steppers?
open frame motors are motors to build into spindles or other special applications
in the case of the skf ones brushless ac motors
what would cause the arrow buttons on my keyboard to have very poor response when jogging, and also the coordinate display on the preview screen in axis to update very slowly? The machine isnt loosing step, it's an EMC/PC issue
i'm running steppers and i have all mesa stuff, including a 5i20
wow, just got an email stating that fadal is out of business
they're liquidating everything
aa-danimal-shop: increase base_period methinks
anyone have some time to helkp me figure out thje homing setup?
jackc: i dont see base period anywhere, just SERVO_PERIOD in my ini
should i add a line for BASE_PERIOD?
i measure my work area size on my table, and still having an issue making my machine home in nthe right side
aa-danimal-shop: pastebin the output of halcmd show thread?
frysteev: does it go the wrong way always, or just when homing?
cradek: will do
when i manually jog it in emc is goes in the correct directions
but it homes to the baCK RIGHT INSTEAD OF FRONT LEFT
ok good, so you have a few things to check: are your homing velocities set right (correct sign) and is the sense of the home switch inputs correct
you can test the home switch inputs using halmeter
the inputs themselves work
i have limit switches on the end of both axis' that i also want to use as home
ok but are they true when on the switch and false when off the switch
ok, so you're sharing home/limit
i havent done any setup stuff oputside of the stepconf qwizard
ok, bring up emc, run halmeter, check axis.0.home-switch-in or however it's spelled
it should be FALSE until you poke the switch, when it should turn to TRUE
[23:00:39] <aa-danimal-shop> http://pastebin.com/Y9qWs3JD
is tkemc likely to go away anytime soon?
ds3: free software never goes away
the switches all work
ds3: tkemc currently doesn't have a maintainer, so it will not get new features, but otherwise it's here to stay
right now ity homes to the back right. then thinks that is the home location aS WELL, and wants to think as that as the front left, but its at the end of its movement
frysteev: just to be clear, you checked axis.0.home-switch-in, .1, .2, and they are TRUE only when you poke the switches?
cradek: so there is no active desire to get rid of it? it'll just sit and rot
ds3: exactly, unless a maintainer steps up, then it can be kept up
my x= 305mm y=460mm and z=120mm of movement
frysteev: so if you home X, you want it to move in the minus direction to find the switch, but it moves plus?
good enough... that'll at least buy me some time before I have to figure out what is really wrong with axis
i think so..
im very noob at this.
aa-danimal-shop: looks like you're spending 20-40% of the machine's time servicing the servo thread
aa-danimal-shop: how about halcmd show funct
frysteev: just to be clear, when you home X, you want to move negative, which means the table itself goes right, right?
my table is stationary, its a gantry router,..
ok, that's easier then
you want it to home X with the tool to the left?
so i want to home front left instead of back right
pull up http://www.linuxcnc.org/docs/html/config_ini_homing.html
in the HOME_SEARCH_VEL section it says that means you should have a negative HOME_SEARCH_VEL. do you?
cradek: it completely locked up now
can i config this in the wizard or do i need to open up something else?
lemme restart it quick
I think you have those same settings in the stepconf wizard, so you should be able to look there
aa-danimal-shop: hm, wonder if you have a hardware problem or something
its a positive number
ok do you see from that section in the docs how that means it should search in the positive direction? make it negative.
then, go on to check HOME_LATCH_VEL
ok lemmie try this
... to do what you want - there are several ways it can work.
cradek: this is a really long g code program, it's like a 2.5 hour cycle time at mostly 15-17ipm. i wonder if that has anything to do with it
aa-danimal-shop: a crazy big preview can make AXIS slow
aa-danimal-shop: you could put (AXIS,stop) in the program to make it not do the preview
oso far so good
(shouldn't lock up your computer, but it can make keyboard response worse)
cradek: my keyboard is acting up now lol
i cant even enter my full user name
it leaves out half the letters
lemme try to swap it
cradek: x and why are awesome now
i blew it out and it works, i think it had chips in it
z i need to home positive,
it does, it moves all the way up then homes, and calls its its start position instead of the end of its travel.
ok, keep reading the homing docs at that url :-)
probably HOME_OFFSET and HOME are what you need to set
cradek: i updated the pastebin
[23:16:32] <aa-danimal-shop> http://pastebin.com/Y9qWs3JD
aa-danimal-shop: can you add halcmd show funct?
oh I see it, http://pastebin.com/5zwE5BP8
weird, I thought show funct showed the timings for the individual functs
gotta run - dinner
show thread maybe?
i did show thread, it's in the pastebin
hmm so my machine puts out 58,666 steps per second, max
is there any other user interfaces to emc then axis? :)
MrSunshine_: a couple
xemc, yemc, tkemc, mini, keystick, halui, touchy, mocca
to name a few
probably left out a couple
mmm touchy http://linuxcnc.org/docs/2.4/html/gui_touchy.html
do you think 58,666 steps per second could be causing my issues?
i'm using a mesa 5i20
aa-danimal-shop: sorry, just came in..
what's the issue?
emc is really sluggish sometimes
well mostly when jogging with the keyboard
it'll be somewhat irratic
thenm i noticed the dro was updating pretty slow
and it completely locked up on me when i had a large program loaded
did you try another gui?
whenever i change a work offset or tool offset, it takes forever to reload
aa-danimal-shop, slow computer? :)
it's been sluggish with the jogging for a long time, but now that i'm trying to run this program, it's giving me alot more issues
MrSunshine_: it's an older compaq server, 1.4ghz P3. had about 13000 for latency
software rendering? :)
sub par, i'm sure
as axis shows everything in 3d ... a slow graphics card can be a pita :P
it's built into the raid controller, and has ethernet as well
got a slow graphics card in my cnc computer and it goes sluggish when offsetting etc
like if you have a cirius logic 4mb it wont do very well in graphics :P
i have no clue what it is
probably bare minimum since it was a server
try like they say with some other gui for it ?
and see if jogging etc still is slow
is there any way to just change the graphics acceleration or any of that stuff to make it better?
aa-danimal-shop, check with glxinfo if you have sw render or not
and check performance in glxgears =)
i have no clue what that is or how to check it
type "glxinfo" in a terminal
and paste the output to a paste bin :P
and if you run glxgears in a terminal you will see how many fps you have
aka graphics card performance test =)
[23:46:30] <aa-danimal-shop> http://pastebin.com/yXysANRd
glxgears started at 224 and went down to 137 eventually
basically at 137-138
is that bad?
getting ~2700 frames per 5 seconds here
aa-danimal-shop, you are on sw render atleast
no direct rendering
is the server supposed to be just for cnc ? :)
if it got agp or something get a cheap 3d accelerated graphics card =)
so cpu wont have to work so hard to render
well, there is 3d accelerated old cards for PCI also =)
strange with a P3 with only PCI imo =)
well there's isa too lol
my lathe runs about 870
aa-danimal-shop, get a used real computer for like $10 insted :P
aa-danimal-shop, or see if you can find a pci 3d accelerated graphics card =)
has to be some used working parts somewhere, i usaly go the recycle center and ask if i can take something when i need something for an old computer =)
yea i'll look around
maybe i'll just spend the $100 and get an atom
a good computer as cnc workstation is a good thing imo =)
do you usually have to reinstall ubuntu when you get a new pc, or can i just swap over the HDD?
It never hurts to do a fresh install, but you cold always try it.
Some have good luck, other's don't.
but I'd backup your data first.
