are you ?
* Phydbleep is busy fighting with the aftermath of a power failure..
how are the cats ?
i've 2 cats now :P
Fleeing in terror... I had to cuss when the power went down..
* robin_z thanks his UPS for being there when needed
anything exciting happening?
you were asking about running stuff on system boot, and grub?
yeah, I found out I need to muck with init insted of the bootloader.
is this something like say, apache or some other app, or is it a system service?
if its a system service, then yeah, init is the place
no, running only keystick as default w/o login upon bootup.
if its an app, like apache, mail system ...
init is possibly not the place as the system will try to start it again if its goes off, which *might* not be what you intend
you know when you design and build something , then find you cannot get it through the door
AchiestDragon Nope, that's what sawzall are for.
Jymmm: maybe just from /etc/rc.d then sitch runlevel to get it there ..
AchiestDragon: oh i *nearly* did worse than that .. built a new shed, sectional, as we came to erect it .. someone asked, "where is the door?" ;)
:) well glad i checked before i started to build it , grrr 40mm too big , to get thrugh the door
and thats if i took the steppers of the end :(
Jymmm: and if you do run from init .. do NOT edit rc.sysinit, edit rc.local instead ... but sometingn in rc.d would probably be better
Well, I'll clueless there... so it'll probably be skipped for now.
I always fancied running the EMC service as root from rc.d, then allowing uses to connect a GUI from their non-root account
ie youd start and connect the machine cotnroller as the box booted, then users would log-in to control it
I want to run a remote gui, X take too many resources for this lil mahcien.
fuck this place is a mess!
what box you gonna run the X server on?
TkEMC on XP
smb and ssh
secure shell, putty
and do ssh -X to the emc machine?
no X at all.
runnng Tk for doze or whatever
TkEMC running on XP can connect to the emcsvr on the emc box
just need samba to transfer files other to the nix filesystem and putty for, well whatever.
TkEMC on XP still ref the nix filesystem.
on a file open I mean
pity it cant do that locally, then upload the file over the link
this has been discussed before
it probably could, but this is a simple enough solution.
did you get me any dat from the tests?
well, just pushing onthe gantry by hand, how much play do you estimate?
on one side ...
1mm? 2mm? more?
whys that? no hands? no machine?
sent t back?
gantry fallen off?
Gnight guys :)

going to have to shoot this G200X soon ...
dosent it work?
havubg trouble getting the encoder inputs goig
no problem in the diagnistics code
but some random problem in my application code ..
so annoying .. the registers on the FPGA just read back as zero .. even though I have set up the counters in the correct way .. sigh.
fpga code broken?
* anonimasu is going to do some machining today
making the next part of "The Plan" harder than it need be ... which was to have an encoder on the front panel and a keypad so I could press a key, and spin the encoder to tunr up/down cutting speed, arc voltage, current, pierce delay etc
no, it runs fine in the diagnostics code ... so the FPGA is doing its thig
did you see that hack on a bank encryption system with an FPGA?
basically, they shpwed how to persuade an IBM encryption module to cough up an encrypted version of the master key
then used a FPGA to crack the cipher ... running 16K trial keys at once
recovered the key in less than 48 hrs
IBM failed to take them seriously / patch it after 18 months ... so they put the code and circuitry on the web :)
I've seen it..
fpga's makes for interesting apps ;)
robin_sz: if there was a compiler that would allow you to code c-ish stuff and compile the algorithm into FPGA components ;)
well, vhdl is sorta C like
sometimes, hardware is better than software ... realtime step generation being an obvious example, jon elsons bord for example
hey, didn't you buy one of those?
I have not heard from that guy I am trying to buy the spindle from
I think I know why
He is in New Orleans
I fear that city is about to get erased from the face of the earth

* anonimasu did some turning on the lathe
now my right hand are all taped up :)
BDI-4.23 is now available...
[15:26:45] <paul_c> http://www.wildrice.com/emc/
in depth details of changes @ www.linuxcnc.org/bdi/
and that's the cvs sources tagged...
ooh, neat -- I've never tried out screen's "multi-attach" mode.
paul_c: "screen" lets you run multiple tty-mode sessions inside one terminal window, and also disconnect from them and later reconnect from a different machine
so it's great to let me type to the same IRC session from home or from work, for example
with "multi-attach" I can apparently leave the same thing displayed in two (real) xterms at the same time
* paul_c googles....
* anonimasu hates screen
I love it
it gives your pinky finger pain ctrl + a...
* anonimasu ends up with too many open terms
you can re-map that .. I actually use ctrl-x, but only because I never use emacs
(I use ctrl-a as 'go to beginning of line' far more often..)
yeah, I should map it to ctrl + b
or just change the way i push it..
it maybe ctrl + x.. it sounds nice
paul_c: Do you know how to remove the bootsplash?
Late night last night ?
hi all, I finally ran into the 1250760 bug last night
Do you want the quick'n'easy way, or the long and involved method ?
([ emc-Bugs-1250760 ] feeds slow after program abort)
paul_c: Q&D would be nice.
I had a program that would start running but then abort when the interpreter would get to a future line that exceeds limits
/boot/grub/menu.lst - Comment out the initrd line(s)
after that, MDI/G0 or the initial G0 moves in the program, when restarted, would go very slowly
paul_c: will that still allow fbconsole to remain?
fbconsole is compiled in
paul_c: Ok, that seems to have done it, thanks. Do you have any idea why the font looks 'choppy' ?
change the vga mode (or remove t) in grub menu.lst
paul_c what does the 't' do?
s/ t/ it/
ok, I see blah... vga=788 should it be something else?
[Global Notice] Hi all. You might have noticed that we're experiencing a large influx of "annoyance bots" sending blank lines of advertisement for porn spam. We are working on the problem as best we can. To avoid getting messages you might want to set yourself +E. Thank you for using freenode and have a great day!
I added that information to the bug report
oh hell.... ok, now how do I remove the bootsplash during shutdown/reboot ?
update-rc.d -f bootsplash remove
what man page is that in?
ok, and what about the vga=788, where could I find other settings?
paul_c: I wanted to set the fbconsole simular to knoppix startup
les no tractor pulls this morning?
ha did yesterday.
you got your tractor stuck in the mud?
I may not get that spindle I wanted...it's in new orleans.
shipping too high?
no...katrina is up to 175 sustained....new orleans is about to be "eliminated"
Jymmm: See kernel source Documentation/svga.txt and...
les OH! ouch
03paul_c * 10emc2/src/emc/ (Makefile log/Makefile motion/Makefile): emcmotlog is redundant code - Removing it from kernel code avoids a compilation failure with 2.6 builds.
$37 for five 45A SSR
paul_c: I couldn't find vga= settings in those docs you gave me (I googles for them), but I was able to find vga=791 from knoppix cd and it works beautifully.
les: how's the router doing, with the fixes to the tp?
it looks good...I am now trying to get a bigger spindle since I can now go faster
Before I didn't bother...the pt bug would have torn the machine apart at high speeds
tp i mean
so no more burns to sand out now?
right....I even have to remove the "anti gouge" I had to program in
That will give the employees more time to chase the girls
It still has issues with improper velocity adapting if segments are very short
but all in all it's much better
that's good to hear
It does velocity adapt to honor velocity and accel settings
I just bought a B'port with a Centroid M40 on it. Eventually, I will be able to do a side by side comparison of it and EMC
but if block rate is beyond maximum the whole thing breaks down
It really needs to adapt such that a certain block rate is never exceeded
Centroid M40 huh?
les did you ever find your tool changer stuff?
early to mid 90's
w/ 4th axis
I still need a second mill but have just about decided to go with a VMC
you could probably find a VMC as cheap as anything and you have the space for one
I just have a 2 car garage
I didn't find much functional ATC stuff in emc jymmm
there is some stuff there...but no comms
thanks for the info les. I need to go pay for the new mill. Time to make some parts.
bah... I have such ahard time mounting a cdrom =(
even under KDE
* paul_c clicks on the cd-rom icon..... mounting cdrom.
* paul_c right clicks and selects "eject"..... cd pops out.
Jymmm: Works for me no probs.
* Jymmm click on the cdrom icon.... mount: wrong fs type, bad option, bad superblock on /dev/hdc, or too many mounted file systems Please check that the disk is entered correctly
Error - kio_devices_mounthelper
Are you in these groups: audio,cdrom,dialout,dip,disk,floppy,games,users,sudo
is your fstab line correct for the CD drive ?
paul_c where would I look?
Is the CD-ROM icon linked to the correct device ?
"id" to find the groups you're a member of
and "ls -l /dev/cdrom"
"groups" will tell you what groups you belong to...
jim disk dialout cdrom floppy sudo audio dip games users
$ ls -l /dev/cdrom
ls: /dev/cdrom: No such file or directory
/dev/hdc /cdrom iso9660 ro,users,noauto,unhide 0 0
should I change that from 'noauto' to 'auto' ?
now "ls /cdrom"
leave noauto alone - This tells linux not to mount the drive at boot time.
ls /cdrom returns nothing
Insert a CD in to the drive, and type "mount /cdrom"
~$ mount /cdrom
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
or too many mounted file systems
sounds like your drive is in the last stages of death.
I just replaced it.
IDE cable the right way round ?
laptop... and the system was just installed using it.
dunno then - The cdrom driver is compiled in to the kernel.... Your fstab line is correct.
Did you change the bios settings ?
weird.... mounted cd1 - no luck. Then mounted the install cd and it worked, then mounted cd1 again and it now works.
sound like flakey hardware...
I just spent 5 hours replacing this cdrom drive yesterday
it worked fien installing bdi
is there a way to 'detect' the fs on the cdrom?
iso, udf, etc
dd of=/tmp/test if=/dev/cdrom; file /tmp/test
/tmp/test: ISO 9660 CD-ROM filesystem data 'BDI-Lite ' (bootable)
jepler does that tell me the actualy fs, or just determine if it's iso9660 ?
Jymmm: it will try to detect the filesystem type.
Jymmm: for instance, "file" says this when I give it the first few hundred K of /dev/hda1:
/tmp/test: x86 boot sector, code offset 0x52, OEM-ID "NTFS ", ...
i don't really have any ideas
jepler: excuse the ignorance, but I dont have a /tmp/test file.
Jymmm: right, you create one with the 'dd' command, like I showed above
dd of=/tmp/test if=/dev/cdrom count=100
$ dd of=/tmp/test if=/dev/cdrom count=100
dd: opening `/dev/cdrom': No such file or directory
Jymmm: instead of /dev/hdrom use /dev/hdc or whatever your cdrom device actually is
hmmmm.... this one disc shows as binary.
is it possible that the disc is bad, not correctly burned, or something?
paul_c: Where can I see what version I've booted up to (4.23)?
dpkg -l | grep emc
jepler: sometime I use fs other than iso9660; juliet, UDF, etc
paul_c: no, no, from the bootable cd
the release notes or .cdinfo
can I get to that from the boot menu?
"file" may not know about all filesystem types.
paul_c can I get to that from the boot menu?
ok, booting into rescue mode
If you boot the CD up in graphical install mode, the "Release Notes" button will bring up the release info & change log.
oh NOW he tells me =)
you didn't wait....
oh shit.... you asked with onboard video, didn't you?
the other way is too look at the front of the CD where someone has used a sharpie to note the ISO details on the label.
paul_c there was no sharpie included with the iso file.
"Free sharpie with every ISO"
paul_c Now, did you need with internal video only?
Just need to know it will boot to the GUI.
but onboard video ?
or that doens't matter
btw, so far it didn't find any hdd's either.
and went into that funky text mode
OK. so it still doesn't detect i810 video
* Jymmm never knows what to call that install mode.
well, i think I'm on the ext video card. but it's saying it cant find hdd's
let me look......
ok, I yanked the ext video card and the 2nd nic. using only onboard stuff and booting now....
Probing for video card: Intel 810
fatal IO error 104
you many now safely reboot your system
jepler ok, thanks =)
Jymmm: Thanks for testing...
J.E. will just have to stop peddling dodgy old Dell machines on the cheap.
paul_c: I was able to get to the text install, but not the gui
who's j.e. ?
paul_c anythnign else?
a beer ?
yes, you do owe me 3 beers now
paul_c ok, if nothign else, I'll put the machien back together now.
once again, thanks for testing.
time for food.
has anyone every noticed that when paul leaves, shortly after Steve does too?
maybe he wants to listen to Paul ??
lil bit, ppl were on earlier
ahhh .... bisto
* robin_sz is having VPN fun ...
paul_c, if you are going to kick me off the channel from time to time, could you at elast have the decency to /msg me to explain why. Thanks
interesting, I bet alex_joni could use these ...
[22:48:52] <robin_sz> http://search.ebay.co.uk/binzel_W0QQfromZR40
some one recomend me a cheap servo controler!!!
cheap and good :)
or do you mean a card for the PC?
i have been banned from using gecko to drive my servo's
master yoda has spoken
oh, then .. you will have to use someting else
yes... that's what i thought... just got no ideas
I have used Baldor products, they are nice
web addy? www.baldor.com
got ... (checks) ... 6 motors and drive of theirs running at the moment
budget around �1000/axis ($1750)
did u c when i said cheap?
specify what you need ... step and direction input?
or -10-0-+10v amps
i actualy havent a idea... just need to read some stuff and c what's out there
i'm new to this
with seperate drive card
Gecko is the best of the cheap bunch .. step/dir input
and u control that off the paralell port
off a source of step and dir, yes ..eg the paralell port
its not a "real" servo in that respect
but if you want real servos ..
budget �500 for the PCI card in the machine
and then add amplifiers and motors
gosh... battle for breath
Jon elson has some amps for not too much
need it to drive this kinda servo "30A peak 90v 3000"
thats within a Geckos range I think ...
well, 20A, 80V
dont know if that will be enough
got a big machine in mind
you could always use Geckos to start with, buy REAL drives once you have it up and running .. geckos eBay for around 10% less than retial it seems
how much $$ geckodriver ?
for 3 motor or 120 for 1 motor ?
i think no half way.. its better
servos or nothing
good or nothing
Hspeed or nothing
do it 1 time only
that what i will do whe i can ..
servos are not always the right choice
for BIG machines yes
Yuga need to work on wood
i'm sure are a good choice for woodworking
at about 300~400W its choice between servos and steppers
below 300W usually steppers
wood require very high speed
i know something now.. :(
define high speed
500 IPM or more..
my router does 600 ipm
not the router..
600 ipm ??
600 ipm on each axis
never losted steps ?
at this speed ? O_o
when its hit someting, sure
or.. you have additional encoder ?
but it runs out wooden parts every day
in reallity, it cold use servo or stepper, its a mid sized machine
who ? Yuga ?
he was talking about 3 mt machine !
3 mt ... yeah, thats up in servo terriotry I guess
mine is a small 3hp machine
Jacky^... no point in doing anything small :)
but .. hes going o have to spend big $$$ on a 3mt machine .. thats going to be running what? 10hp +
Yuga: yeah ..
my small experience agree ..
better to spend one time only, maybe
Jacky^... problem with that is that if u mess up u mess up big
hence the reason i dont intend on messing up
i spent about E. 300 with toys part
just to learn :(
the geckos are nto "real" servos, but come close, and the eBay price seems to be about retial -20% or so
so not a big deal to start that way
aparently there where nice servo drivers on ebay... but they are gone now :<
Yuga: i think it's hard
we need to search every day on ebay for it..
the bad thing, after build a 'customized' machine
it's very hard to sell it without lost 50% :(
problem i have with buying from ebay is if it breaks... where i get a new one?
anyone want to build customized machine
with his hand..
and his needs
Yuga: i think it's not a big prob
you can also buy different parts, motors, drivers..
probably, better way is just to start build a machine
and going on, buy the parts as you need
starting with slides :)
im building one already
during the build you can understand better what you really need
of course, if you find a good price motors or drivers..
thows latest plans for a mdf design in the bin
buy it immediatly !
need something a bit stronger
and easyer to make
instead, if you want to calculate everything before.. any screw.. you could make a mistake..
losting money :(

but at almost 3kg per meter its going to be heavy
may have somthing capable of milling brass then :)
