I wonder how fast he's going?

wasn't paying attention
that didn't happen in 10 seconds
reminds me of work. the machine shop bought a nice old drill press - the table was perfect.
then the owner of the company came down to use it for a second - drilled right into the table.
well at least he can't chew anybody out about it
why do you tell us sad stories =(
Penn State was selling a very old bridgeport a few years back that had a table that looked like the surface of the moon
I have no idea how a lot of the damage could have happened
I guess after the first few hundred drill strikes, there is no incentive not to use the mill table as an anvil
that's very sad
old machines don't die, they just get neglected and abused
that machine was at least usable as a mill with a little work
we had an old horizontal mill that had been converted into a really stupid bearing test stand
the 14' planer would straiten it back out ;)
and I've seen at least one vertical mill that was modified into something that couldn't cut any more
I'm sure there have been quite a few more, Universities are good at creative destruction
that's definitely true
high schools too
I really should be unpacking boxes.
or go to bed
bed it is - night ;)
anybody know what "VFS: busy inodes on changed media" means?

thou shouldst not eject thy CD-ROM with out unmounting it
(did so yesterday - its been putting several messages into the kernel log every second for over 24 hours)
heh - 106070 lines of that message in /var/log/messages.... 26 lines that _aren't_ that message
doesn't linux syslog say "last line repeated 10000 times"?
I recall seeing that in the past (other distros)
don't recall seeing it lately
it's funny how some software gets better and some breaks over time
there were 46688 instances of that message in the messages.0 too...
I'm glad I happened to look at the log (checking something completely unrelated)
it was going at something like 16 megabytes per day
is it on the root filesystem?
not sure if var is on its own partition
from "man sysklogd", regarding how to deal with users who are flooding the logs:
5. Use step 4 and if the problem persists and is not secondary to a
rogue program/daemon get a 3.5 ft (approx. 1 meter) length of
sucker rod* and have a chat with the user in question.

A question about the 'setsmi' command - is there a recommended way to have it run when EMC starts, or should I just put line into rc.local?

would it be worthwhile fitting one of those micro keyboard vaccuums on a spindle for particle collection (i.e. PCB milling) and air cooling?
have enough suction?
no idea, just see them cheap (~$5)
cheap shopvac might be better
at the expense of being loud as hell
but a cheap shop vaccum means i have to run an unweildy hose
have a link?
I vote against all cheap tools
these flash windows server ads are obnoxious

'so and so wins big with rock solid reliability ..."
I disable flash all together
"we weren't getting it from our legacy infrastructure"
most likely the old infrastructure was ms based too?
the ad should read, " We bought the new version from the same company because the older one was shitty. This has nothing to do with being better than Linux"
maybe I'm just pissed because they run two win 2003 boxes at work
on another note, hard to beat trying it out fro only $1.74
going to attach it directly to the side of the spindle?
this is on a tiny desktop mill
the USB power is a plus, one less power cube
yes; a Taig
I was engraving plastic a few weeks ago and it took hours to clean up the spray of plastic "chips"
invest in a regular vacuum cleaner first then ;)
who was the one milling on their bed?
it is the hose routing problem
I've seen a picture of a mill on his bed
but I don't think he was cutting there

alex_joni: I know :(
first paragraph isn't that bad.
stopped after that.
humm, you people who know a thing or two :) .. Bipolar stepper motors they have to have a negative voltage also or is it just to reverse the poles? :)
MrSun: L298 is a chip that can drive bipolar steppers with positive supply only. It still requires two supply voltages, well-regulated 5V for logic and 12..46V for motor power.
MrSun: most bipolar stepper drivers work in a similar fashion to the L298, using the structure called an "H-bridge" which can connect each side of a motor winding to either Vdrive or GND
usually used in combination with L297, which takes step+direction input
to weak :P
found engines very very cheap if i can get my father to buy them as they only sell to people with a company ... 12.5Nm holding but sucks in 4.5A :)
hmm - I would look at gecko then..
there are many different H-bridge stepper drivers out there
the bipolar drive ri have for my small engines i found on another page and it said it could take 5A :P
L298 is just one example
the humm .. what is they named .. the big ones of transistors? :P
are rated for like 12A and 48A or something like that :)
gah all h-bridges i find is to small :)
besides adequate current rating, other important properties for a stepper driver include: half-stepping or microstepping, current limiting or "chopper" circuit, and input voltage several times the steppers' rated voltage.

jepler, yeah figured when i noticed one of the ones i found had micro stepping :)
many people report that http://geckodrive.com/
are great, except that you can't change the 10x microstepping
(often 10x microstepping means too many steps per second for software step generation)
while it does have a bias towards gecko drives, this is a very good article on what it takes to drive a stepper well: http://geckodrive.com/photos/Step_motor_basics.pdf
(everything in there rings true to me, except that I haven't ever experienced 'mid-band resonance')

do you have access to google?
if you no want help-me very tanks
I'm trying to help you learn how to find information for yourself
google is a good place to start
if you ask people lots of simple things that are easy to answer by yourself, they will not want to help you when you have a hard question
yelling (typing your question in all caps looks like yelling) makes it much worse

I saw lots of cnc machines today
big ones :)
haha, not too hard to fill in the blanks there
and a laser..
8 of them
I think they had 18 machines where I visited
all in use?
or a surplus sales place?
all in use
though they were to big to see the actual machining
what does this factory/shop make?
I was looking at the entry moves on that g-code you sent me .. they are a little strange
heh.. it's a CAM option
and I think it's quite usefull..
(I agree they could be smarter)

<-- ehm .. what is that "nut chip" .. looks like something interesting :P
or is it just an ordenary microprocessor? :)0
NUT chip must be some small microcontroller
it looks like some kind of CPLD
"Nutchips are different because they use truth tables instead of a programming language."
that design seems to lack current feedback, which is necessary for decent performance in stepper motor drivers
ye .. just looked at it if it could be usefull :)
its a tad to much theory behind driving these damn things effiently :P
is there any electornic program like electronic workbench for linux? :)
I'm not familiar with that program. There are some circuit simulation programs for linux but I do not have more than one hour of experience with any of them, and I have forgotten the names.
yeah .. circuit simulation .. thats what its called :)
you are looking for spice & co

bytecolor: I am sure there is some way
bytecolor: from the man page for 'menu', you can bind something to the <<MenuSelect>> event, and that binding is called when the active item changes.
bytecolor: you could put code in that binding to display the cascade menu if the item is a cascade
jepler, I see. yeah I dont think it's common knowledge, though. Every Tkinter app I've tried, you have to click the menu, instead of having it auto-raise when hovered over
just a small annoyance :)
It's not so bad for main menus, but for right click popups...
Danial Falk pointed me to some popup menu code you posted once
good night all
Mr. SUn: there are Tcl/Tk circuit simulators like a very basic Electronic Workbench ( drop ic on grid, wire, make, led go blinky ) http://linux.softpedia.com/progScreenshots/KTechlab-Screenshot-1945.html http://ksimus.berlios.de/screenshot.html http://www.tetzl.de/java_logic_simulator.html#download
just a few of 'em
that first isnt Tk, is it?
bytecolor: right. here's tcl/tk stuff tkgate & gmac ( the macro assembler for new gates to use with tkgate ) http://packages.ubuntulinux.org/hoary/source/tkgate
my aplogies for that another guy from Brazil

its ok, he's pretty frustrated
I think this can be useful with hal_input
nice, a usb with breadboard?
tomp: yes i think so
i just find that link
[21:20:15] <danielbr> http://www.lvr.com/hidpage.htm
someone can tell me how is possible mesure latencies for hal_input signals
i'm thinking use one signal and two optos output.opto1 hook in a parport pin output2 hook hook in a hal_input pin and comparethe delay in halscope
danielbr: sounds like the right beginning, someone here might be able to advise how to do this.. automate and log the signals, so the latency can be observed while you 'aggravate' the system.
tomp: what you think about use some analog input from a device like these picusb for EDM feedback?
Got a passwd problem
a question for #ubuntu maybe
sudo wouldn't work, su would, so I su myself, blew away the root entry in nthe passwd file & that didn't fix sudo
So now I'm hosed
gene_: boot in "recovery" mode, and put a valid sudoers file in place. my sudoers file is shown here: http://pastebin.ca/417465
you would only need to add the lines which are not blank or comment
# This file MUST be edited with the 'visudo' command as root.
after you get this fixed up, you will avoid certain kinds of foot-shooting events if you follow that advice.
i tested a joypad with hal_input, it seems very responsive
gene_: if you toasted some entries in /etc/passwd or /etc/shadow you will have to put them back as well. my entries shown here: http://pastebin.ca/417477

jepler: after that change what latency is normal? (average)
can you bet some number?
danielbr: no bets
it is probably not a big difference
whatever you do, it's not realtime so the worst-case delays are unbobunded
what is the cardinal sin of a machine control app?
killing the operator
oops - gotta run. bbl
the cardinal sin of a machine control ap
is reminding the operator they're using a machine controller.
is it plunging hte tool through the machine base?
machine toos suck anyway
robot operated tools. much better
